of the defects of the seeder's fertilizing machinery through the mastery and analysis of existing technologies; Using TRIZ tools to solve problems refers to the use of TRIZ related principles such as analysis of technical contradictions and analysis of physical contradictions.Finally, the threedimensional drawing and prototyping are determined, and the relevant performance parameters of the prototype are tested and verify the correctness of TRIZ theory.
Fig. 2. Strainer system nine screen. Through the analysis of the above nine-screen diagram, it can be concluded that hand-held fertilizer applicators and single fertilizer applicators have a single structure and artificial regulation, affecting the overall fertilization effect and fertilization efficiency and fertilization, such as artificial fertilization, spreading fertilizer, etc., are uneven in fertility and have a large randomness, affecting the final operating efficiency and the level of crop growth. 2.2.2 Functional Analysis The working principle of the traditional seeder fertilizing machinery: The sprocket is connected between the ground wheel and the fertilizer device, and the locomotive runs to provide a power source to drive the ground wheel to rotate, the sprocket drive drives the fertilizer device to rotate, and the fertilizer enters the row fertilizer wheel through a preset row of fertilizer device openings(Cela S. et al. 2011). Fertilizer discharge through the row of fertilizer shaft rotation to achieve fertilization.(Gregoret M C. et al. 2011). According to the working principle of the rower system, establish a functional model of the system, as shown in Figure 3.

（1）The fertilizer tank is in direct contact with the fertilizer, and the fertilizer tank has a supporting effect on the fertilizer;
3.2 Solve the physical contradiction
（2）The fertilizer is filled with fertilizer tanks at the time of the row of fertilizers, and the fertilizer exerts pressure on the fertilizer and wear and corrosion.
Physical contradiction description: if the planter is working, it requires a larger tank size to accommodate the fertilizer and a smaller volume when not in use. According to the principle of time separation, the principle diagram is shown in Figure 4. The solutions that can be obtained are as follows:
（3）When the locomotive is moving forward, the soil will have a certain friction with the ground wheel, and at the same time, the ground wheel will be easily affected by the soil and produce slipping. 3. APPLYING TRIZ THEORY TO SOLVE SYSTEM PROBLEMS Through the analysis of the overall system, the cause of the system is finally determined, And summarize the final results of the defects present in the system. For the defects in the system, using the TRIZ theory to make innovative improvements to the problem(Schmidt J. et al. 2011).
Fig. 4. Time separation diagram. Option 1: The fertilizer part of the seeder is made into a plurality of detachable devices. The fertilizer box can be removed when it is placed, or the number of boxes can be added according to actual production.
3.1 Conflict Matrix According to the overall analysis of the system, the technical contradictions are expressed as: if the variable rate fertilizer device can increase, it can also consume less power; if the components are increased, the versatility of the system will be reduced.
Option 2: Changing the structure of the fat box into a collapsible fertilizer box，it can reduce the volume of the fertilizer box when the planter is not working.
Check the TRIZ contradiction matrix and determine its engineering parameters according to the principle of the invention: The improved parameter is the degree of automation of No. 38, and the deteriorated parameter is the energy consumption of No. 19 moving object. By querying the 39x39 contradiction matrix, It is known that the possible solution set is M38-19=[32,2]; No.32 Changes the colour, mimetic state; No.2 Extraction. Then, according to the above look-up table and analysis, we can choose the principle of the invention and get the following solution:
3.3 Field Analysis Solution Problem description: there are many uncontrollable external factors in the actual operation production of row fertilizer organizations, such as the complexity of the landform, the amount of rainwater, etc. It will cause greater system control error. According to the problems generated by the system, establish the object model, as shown in Figure 5.
Option 1:According to No.32. Change the colour and mimic principle , the interior of the tank is painted to improve corrosion resistance. Option 2: According to No.32. Change the colour and mimic principle , the row fertilizer wheel is selected as a material with high corrosion resistance, and at the same time, the opening of the row fertilizer is changed. Fig. 5. Field model.
Option 3: According to No.2 Extraction principle, separating nitrogen, phosphorus, and potassium fertilizers.
The general solution of the object model is: Replace the original field F1 with another field F2; add another field F2 to reinforce the useful effect; add the substance S3 and add another field F2 to reinforce the useful effect. Through analysis, we chose to add a substance S3 to solve the problem
Option 4: According to No.2 Extraction principle, separating the ground wheel and the sprocket, then extracting the sprocket section.

of insufficient effect in the object field model, and to arrive at a new object field model as follows:
Fig. 7. Electric row fertilizer. Fig. 6. New object model By analyzing the object field and applying the standard solution, the following solution can be obtained: Option 1:The introduction of substance S3 is the motor, changing the power source of the rower to the motor. Option 2: The introduction of substance S3 is the wireless transmission module, ensuring that the locomotive work speed is consistent with the amount of fertilizer.
According to the innovative design scheme of the planter's fertilizing mechanism, the prototype is processed and the field test is conducted.Measured by the NPK fertilizer actual fertilization amount, speed, wireless module transmission accuracy and other parameters, field tests shown in Figure 9.After testing, the overall fertilization mechanism can reach the expected standard and meet the national standard and agronomic requirements.At the same time, the validity and correctness of the innovative design scheme of the motor structure based on the TRIZ theory are also verified.
4. TECHNICAL PROGRAM ARRANGEMENT AND EVALUATION Through the use of TRIZ tools such as physical contradiction analysis and contradiction analysis of the physical field, designed electric type fertilizer device. Through the changes of the row fertilizer device and the structure of the fertilizer box, the effects of nitrogen, phosphorus and potassium fertilizers can be achieved, which lays the foundation for variable fertilizer application. The structural innovation design scheme is as follows: (1) Changed the power source of the row of fertilizers from the ground wheel to a motor and designed an electric-type fertilizer device that integrates the motor and the fertilizer. (2) The fertilizer box was changed into an integrated threebox structure, and nitrogen, phosphorous and potassium fertilizers were distributed to lay the foundation for variablerate fertilization. (3) Establish a wireless transmission module for the speed of the fertilizer feeder and the forward speed of the locomotive to ensure the consistency of the speed. At the same time, establish a speed control system for the fertilizer shaft and adjust the amount of fertilizer in real time. The design of the electric power plant is as follows:
Fig. 8. Field trials. 5. CONCLUSIONS (1) Using the TRIZ theory to innovate design and adopting TRIZ basic principles such as the principle of contradiction matrix solution, innovations and improvements have been made to the existing planter fertilizing device structure.The integrated structure of the feeder and the motor can reduce the volume; at the same time, it has a matching control system, which can realize variable-rate fertilization control of nitrogen, phosphorus and potassium fertilizers. (2) Field trials verify that the implement has a good performance of sowing, and all indicators are in line with national standards. (3) Theoretically, the structural design scheme that best meets the TRIZ innovation principle is obtained.The structural design of the optimal fertilization mechanism can meet the performance requirements of intelligent seed drills.It shows

of the defects of the seeder's fertilizing machinery through the mastery and analysis of existing technologies; Using TRIZ tools to solve problems refers to the use of TRIZ related principles such as analysis of technical contradictions and analysis of physical contradictions.Finally, the threedimensional drawing and prototyping are determined, and the relevant performance parameters of the prototype are tested and verify the correctness of TRIZ theory.
Fig. 2. Strainer system nine screen. Through the analysis of the above nine-screen diagram, it can be concluded that hand-held fertilizer applicators and single fertilizer applicators have a single structure and artificial regulation, affecting the overall fertilization effect and fertilization efficiency and fertilization, such as artificial fertilization, spreading fertilizer, etc., are uneven in fertility and have a large randomness, affecting the final operating efficiency and the level of crop growth. 2.2.2 Functional Analysis The working principle of the traditional seeder fertilizing machinery: The sprocket is connected between the ground wheel and the fertilizer device, and the locomotive runs to provide a power source to drive the ground wheel to rotate, the sprocket drive drives the fertilizer device to rotate, and the fertilizer enters the row fertilizer wheel through a preset row of fertilizer device openings(Cela S. et al. 2011). Fertilizer discharge through the row of fertilizer shaft rotation to achieve fertilization.(Gregoret M C. et al. 2011). According to the working principle of the rower system, establish a functional model of the system, as shown in Figure 3.

（1）The fertilizer tank is in direct contact with the fertilizer, and the fertilizer tank has a supporting effect on the fertilizer;
3.2 Solve the physical contradiction
（2）The fertilizer is filled with fertilizer tanks at the time of the row of fertilizers, and the fertilizer exerts pressure on the fertilizer and wear and corrosion.
Physical contradiction description: if the planter is working, it requires a larger tank size to accommodate the fertilizer and a smaller volume when not in use. According to the principle of time separation, the principle diagram is shown in Figure 4. The solutions that can be obtained are as follows:
（3）When the locomotive is moving forward, the soil will have a certain friction with the ground wheel, and at the same time, the ground wheel will be easily affected by the soil and produce slipping. 3. APPLYING TRIZ THEORY TO SOLVE SYSTEM PROBLEMS Through the analysis of the overall system, the cause of the system is finally determined, And summarize the final results of the defects present in the system. For the defects in the system, using the TRIZ theory to make innovative improvements to the problem(Schmidt J. et al. 2011).
Fig. 4. Time separation diagram. Option 1: The fertilizer part of the seeder is made into a plurality of detachable devices. The fertilizer box can be removed when it is placed, or the number of boxes can be added according to actual production.
3.1 Conflict Matrix According to the overall analysis of the system, the technical contradictions are expressed as: if the variable rate fertilizer device can increase, it can also consume less power; if the components are increased, the versatility of the system will be reduced.
Option 2: Changing the structure of the fat box into a collapsible fertilizer box，it can reduce the volume of the fertilizer box when the planter is not working.
Check the TRIZ contradiction matrix and determine its engineering parameters according to the principle of the invention: The improved parameter is the degree of automation of No. 38, and the deteriorated parameter is the energy consumption of No. 19 moving object. By querying the 39x39 contradiction matrix, It is known that the possible solution set is M38-19=[32,2]; No.32 Changes the colour, mimetic state; No.2 Extraction. Then, according to the above look-up table and analysis, we can choose the principle of the invention and get the following solution:
3.3 Field Analysis Solution Problem description: there are many uncontrollable external factors in the actual operation production of row fertilizer organizations, such as the complexity of the landform, the amount of rainwater, etc. It will cause greater system control error. According to the problems generated by the system, establish the object model, as shown in Figure 5.
Option 1:According to No.32. Change the colour and mimic principle , the interior of the tank is painted to improve corrosion resistance. Option 2: According to No.32. Change the colour and mimic principle , the row fertilizer wheel is selected as a material with high corrosion resistance, and at the same time, the opening of the row fertilizer is changed. Fig. 5. Field model.
Option 3: According to No.2 Extraction principle, separating nitrogen, phosphorus, and potassium fertilizers.
The general solution of the object model is: Replace the original field F1 with another field F2; add another field F2 to reinforce the useful effect; add the substance S3 and add another field F2 to reinforce the useful effect. Through analysis, we chose to add a substance S3 to solve the problem
Option 4: According to No.2 Extraction principle, separating the ground wheel and the sprocket, then extracting the sprocket section.

of insufficient effect in the object field model, and to arrive at a new object field model as follows:
Fig. 7. Electric row fertilizer. Fig. 6. New object model By analyzing the object field and applying the standard solution, the following solution can be obtained: Option 1:The introduction of substance S3 is the motor, changing the power source of the rower to the motor. Option 2: The introduction of substance S3 is the wireless transmission module, ensuring that the locomotive work speed is consistent with the amount of fertilizer.
According to the innovative design scheme of the planter's fertilizing mechanism, the prototype is processed and the field test is conducted.Measured by the NPK fertilizer actual fertilization amount, speed, wireless module transmission accuracy and other parameters, field tests shown in Figure 9.After testing, the overall fertilization mechanism can reach the expected standard and meet the national standard and agronomic requirements.At the same time, the validity and correctness of the innovative design scheme of the motor structure based on the TRIZ theory are also verified.
4. TECHNICAL PROGRAM ARRANGEMENT AND EVALUATION Through the use of TRIZ tools such as physical contradiction analysis and contradiction analysis of the physical field, designed electric type fertilizer device. Through the changes of the row fertilizer device and the structure of the fertilizer box, the effects of nitrogen, phosphorus and potassium fertilizers can be achieved, which lays the foundation for variable fertilizer application. The structural innovation design scheme is as follows: (1) Changed the power source of the row of fertilizers from the ground wheel to a motor and designed an electric-type fertilizer device that integrates the motor and the fertilizer. (2) The fertilizer box was changed into an integrated threebox structure, and nitrogen, phosphorous and potassium fertilizers were distributed to lay the foundation for variablerate fertilization. (3) Establish a wireless transmission module for the speed of the fertilizer feeder and the forward speed of the locomotive to ensure the consistency of the speed. At the same time, establish a speed control system for the fertilizer shaft and adjust the amount of fertilizer in real time. The design of the electric power plant is as follows:
Fig. 8. Field trials. 5. CONCLUSIONS (1) Using the TRIZ theory to innovate design and adopting TRIZ basic principles such as the principle of contradiction matrix solution, innovations and improvements have been made to the existing planter fertilizing device structure.The integrated structure of the feeder and the motor can reduce the volume; at the same time, it has a matching control system, which can realize variable-rate fertilization control of nitrogen, phosphorus and potassium fertilizers. (2) Field trials verify that the implement has a good performance of sowing, and all indicators are in line with national standards. (3) Theoretically, the structural design scheme that best meets the TRIZ innovation principle is obtained.The structural design of the optimal fertilization mechanism can meet the performance requirements of intelligent seed drills.It shows
