[0002] In modern agricultural production, fertilization and sowing are crucial links that directly affect the growth and yield of crops. The traditional way of fertilization is usually to spread fertilizer directly on the soil surface. When it rains, the fertilizer is easily lost with rainwater, which not only causes fertilizer waste, but also may pollute the environment. Moreover, the fertilizer on the soil surface may come into contact with the seeds, affecting the normal germination and growth of the seeds.

In the present invention, the conical block and the fertilizer barrel are pushed downward by the second electric telescopic rod and the third electric telescopic rod at the same time, and the conical block and the fertilizer barrel are inserted downward into the soil. When the lower surface of the connecting plate contacts the soil, the third electric telescopic rod pushes the first connecting rod upward, and the first connecting rod pulls the conical block upward through the pull rod.

At the same time, since the insecticide is sprayed in the soil, not only the moisture of the soil is increased, but also the fine soil is wrapped around the surface of the seeds. At the same time, the insecticide sprayed on the soil can effectively prevent pests from gnawing the seeds, thereby increasing the germination rate of the seeds to a certain extent.

[0042] 3. In the present invention, the annular rotating plate and the stirring rod are driven to rotate by the connecting tube, and the stirring rod stirs the soil on the circular loosening plate, thereby achieving the purpose of breaking up the soil blocks. In the process of the movable frame driving the circular loosening plate to move forward, the circular loosening plate shovels the soil, causing part of the soil to slide down into the holes remaining after the fertilizer cylinder is pulled out, thereby burying the fertilizer in the soil. It can not only effectively avoid the loss of fertilizer, but also avoid direct contact between seeds and fertilizer, reducing the impact of fertilizer on seeds. BRIEF DESCRIPTION OF THE DRAWINGS

The limit plate 42 cooperates with the free end of the filter screen 10. When the connecting cylinder 8 rotates, the limit plate 42 presses the free end of the filter screen 10 downward, thereby making the free end of the filter screen 10 tilt downward, making it easier for larger soil blocks remaining on the filter screen 10 to slide down through the free end of the filter screen 10.

[0083] A first material guide plate 43 is provided on the lower side of the filter screen 10, and the first material guide plate 43 is fixedly connected to the inner wall of the movable frame 1 in an inclined manner. The lower end of the first material guide plate 43 is located at the lower side of the strip sowing port 12.

[0086] Working principle: Push the mobile frame 1 to the land where sowing is required, pour fertilizer, seeds and pesticide into the fertilizer loading box 3, the sowing box 11 and the containing box 46 respectively, and slowly push the mobile frame 1 forward, and the fertilizer in the fertilizer loading box 3 slides down into the fertilizer barrel 5 through the fertilizer output pipe 4, and at the same time, the second electric telescopic rod 20 and the third electric telescopic rod 23 are turned on, and the second electric telescopic rod 20 and the third electric telescopic rod 23 simultaneously push the conical block 6 and the fertilizer barrel 5 downward, and the conical block 6 and the fertilizer barrel 5 are inserted downward into the soil. When the lower surface of the connecting plate 19 contacts the soil, At this time, the third electric telescopic rod 23 pushes the first connecting rod 21 upward, and the first connecting rod 21 pulls the conical block 6 upward through the pull rod 22. When the tip of the conical block 6 is located inside the fertilizing cylinder 5, the lower port of the fertilizing cylinder 5 is in an open state, and the fertilizer in the fertilizing cylinder 5 slides downward through the lower port of the fertilizing cylinder 5 to the hole remaining after the conical block 6 is removed from the soil. At this time, the second electric telescopic rod 20 pulls the connecting plate 19 upward, so that the connecting plate 19 pulls the fertilizing cylinder 5 out of the soil upward. When the lower port of the fertilizing cylinder 5 contacts the conical block 6, the second electric telescopic rod 20 The fertilizer barrel 5 and the conical block 6 are pushed upwards at the same time as the third electric telescopic rod 23. When the upper surface of the first connecting rod 21 contacts the push plate 26, the first connecting rod 21 pushes the push plate 26 upwards, driving the L-shaped connecting rod 25 and the limiting block 24 to move upwards. When the lower end of the limiting block 24 moves away from the upper port of the fertilizer output pipe 4, the spring 27 is in a contracted state, and the positions of the fertilizer barrel 5 and the conical block 6 are restored, and the fertilizer in the fertilizer loading box 3 slides downwards through the fertilizer output pipe 4 again into the fertilizer barrel 5, thereby realizing fertilization of the soil and preventing the fertilizer from being on the soil surface. In rainy weather, fertilizer is lost and the contact between fertilizer and seeds can be avoided, which may affect the normal germination of seeds. When the third electric telescopic rod 23 pulls the first connecting rod 21 downward, the push plate 26 is separated from the upward thrust of the first connecting rod 21. At the same time, through the elastic force of the spring 27, the spring 27 pushes the push plate 26 downward and drives the L-shaped connecting rod 25 and the limiting block 24 to move downward. When the lower end of the limiting block 24 is inserted into the upper port of the fertilizer output pipe 4, the upper port of the fertilizer output pipe 4 is in a closed state, thereby preventing the fertilizer from continuing to slide downward through the fertilizer output pipe 4.

[0087] Start the fourth electric telescopic rod 32, which pushes the first sliding plate 28 downward, driving the second sliding plate 29, the connecting tube 8, and the circular loosening plate 7 to move downward. When the circular loosening plate 7 contacts the soil, the first drive motor 33 and the second drive motor 36 are turned on. The first drive motor 33 drives the connecting tube 8 to rotate through the cooperation of the first sprocket 34 and the first chain 35. The connecting tube 8 drives the circular loosening plate 7 to rotate. During the rotation of the circular loosening plate 7, the soil is shoveled, and the fourth electric telescopic rod 32 continues to push the connecting tube 8 and the circular loosening plate 7 downward through the first sliding plate 28, so that the circular loosening plate 7 is inserted into the soil during the process of shoveling the soil.

[0088] In the process of the connecting tube 8 driving the circular loosening plate 7 to rotate, the annular rotating plate 48 and the stirring rod 49 are also driven to rotate. The stirring rod 49 stirs the soil on the circular loosening plate 7, thereby achieving the purpose of breaking the soil blocks. In the process of the moving frame 1 driving the circular loosening plate 7 to move forward, the circular loosening plate 7 shovels the soil, causing part of the soil to slide down into the holes remaining after the fertilization tube 5 is pulled out, thereby burying the fertilizer in the soil. It can not only effectively avoid the loss of fertilizer, but also avoid direct contact between seeds and fertilizer, reducing the impact of fertilizer on seeds. Since the multiple stirring rods 49 are distributed in a ring shape from the inside to the outside, the stirring rods 49 block larger soil blocks on the outside, and the finer soil enters the connecting tube 8 through the arc-shaped feed port 39 during the forward movement of the moving frame 1 and the pushing of the stirring rod 49.

[0089] The second driving motor 36 drives the rotating shaft 40 to rotate through the cooperation of the second sprocket 37 and the second chain 38, and drives the spiral conveying plate 9 to rotate. The rotation direction of the spiral conveying plate 9 is opposite to the rotation direction of the connecting cylinder 8. During the rotation process, the spiral conveying plate 9 transports the soil entering the connecting cylinder 8 through the arc-shaped feed port 39 upward, and slides downward to the guide plate 31 through the gap between the connecting cylinder 8 and the first sliding plate 28, and slides down to the filter screen 10 through the inclined surface of the guide plate 31, and the fine soil slides downward to the first guide plate 43 through the holes on the filter screen 10, while the soil with larger particles stays on the filter screen 10, wherein the rotating end of the filter screen 10 is fixedly connected with a baffle, which can effectively prevent the soil from remaining on the filter screen 10 The rotating end of the filter screen 10 slides downward onto the first guide plate 43, and in the process of the connection tube 8 rotating, the limit plate 42 is driven to rotate. Since the limit plate 42 is spiral, when the limit plate 42 contacts the free end of the filter screen 10, that is, the upper end of the filter screen 10, the free end of the filter screen 10 is pushed downward by the inclined surface of the limit plate 42 during the rotation. When the free end of the filter screen 10 faces downward, the soil remaining on the filter screen 10 slides down through the inclined surface of the filter screen 10 and slides down through the rectangular through hole on the movable frame 1 onto the soil. When the fine soil that slides down onto the first guide plate 43 passes through the receiving box 46, the nozzle 47 is turned on at this time, and the nozzle 47 injects the receiving box 46 into the soil. The insecticide loaded inside is sprayed on the soil sliding down through the first guide plate 43, and the first electric telescopic rod 14 is turned on at the same time. The first electric telescopic rod 14 pushes the baffle plate 13 in the direction away from the strip sowing port 12, and drives the movement of the anti-blocking rod 15, wherein the anti-blocking rod 15 is located at the edge of the baffle plate 13. When the anti-blocking rod 15 contacts one of the side walls of the strip sowing port 12, the strip sowing port 12 is in an open state at this time, and the seeds in the sowing box 11 slide down through the strip sowing port 12 to the first guide plate 43 and mix with the soil sprayed with the insecticide on the first guide plate 43, and the soil mixed with the seeds slides down to the second guide plate 44, and slides down through the second guide plate 44 and the strip discharge port 45 to the soil on the lower side of the movable frame 1 In the process, the seeds are sown, and at the same time, since the pesticide is sprayed in the soil, it not only increases the moisture of the soil, but also facilitates the fine soil to wrap around the surface of the seeds. At the same time, the pesticide sprayed on the soil can effectively prevent pests from eating the seeds, thereby increasing the germination rate of the seeds to a certain extent. When the first electric telescopic rod 14 drives the baffle plate 13 to move back, the anti-blocking rod 15 moves back with the baffle plate 13. When the anti-blocking rod 15 contacts the other side wall of the strip sowing port 12, the strip sowing port 12 is in a closed state, so that the strip sowing port 12 is intermittently opened to avoid excessive outflow of seeds through the strip sowing port 12, which causes the seeds to accumulate on the soil. At the same time, the back and forth movement of the anti-blocking rod 15 can prevent the seeds from being blocked in the strip sowing port 12.
