Description

Technical Field

[0001] This invention relates to the field of seed sowing technology, and specifically to a strip-shaped, reel-type integrated seed and fertilizer sowing device. Background Technology

[0002] Seed weaving technology involves wrapping crop seeds in biodegradable paper strips at specific intervals. During sowing, the seed-wrapped paper strips are laid on the soil; after watering, the paper strips dissolve, and the seeds sprout. This technology is particularly suitable for crops with expensive or small seeds, or for crops requiring controlled plant spacing. The weaving machine precisely controls the plant spacing during the seed-wrapping process, with a seed spacing error of no more than ±1 mm. It ensures accurate seed distribution and eliminates the need for manual thinning later, saving significant manpower and resources. This technology is applicable to the sowing and cultivation of various crop seeds, including root vegetables, leafy vegetables, fruit vegetables, flowers, and medicinal herbs.

[0003] In the existing technology, when a paper strip containing fertilizer and seeds is sown into a pre-dug trench, the paper strip and the fertilizer and seeds inside are relatively light. If strong winds occur during the sowing process, the paper strip can easily be blown out of the trench, causing the actual sowing position of the seeds to deviate from the preset strip layout. This interferes with the normal operation of the seeder and has an adverse effect on the efficiency and quality of seed sowing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a strip-wrapped reel-type integrated seed and fertilizer sowing device.

[0005] A strip-shaped, reel-type seed and fertilizer integrated sowing device includes a device body. A fixed frame is installed on the top of the device body. A rotating frame is rotatably installed inside the fixed frame. Four reels are installed inside the rotating frame through four sets of limiting mechanisms. The surface of each of the four reels is wound with a paper strip containing seed and fertilizer. A guide wheel is rotatably installed at the bottom of the fixed frame to guide the unfolded paper strip downwards. A guiding mechanism is also provided inside the fixed frame to drive the paper strip to be quickly discharged into the trench. Both outer walls of the fixed frame are provided with a soil-pushing mechanism to push some soil into the trench and limit the paper strip.

[0006] Optionally, the front end of the device body is provided with a connecting part, two movable wheels are installed at both ends of the bottom of the device body, a fixed plate is installed at the bottom of the tail end of the device body, a trencher is rotatably installed inside the fixed plate, and a first drive motor with its output end connected to the rotating part of the trencher is installed on one side of the outer wall of the fixed plate.

[0007] Optionally, a second drive motor is installed on one outer wall of the fixed frame, and the output end of the second drive motor is connected to the rotating part of one end of the rotating frame.

[0008] Optionally, the limiting mechanism includes two placement slots opened on the rotating frame, and the fixed shafts at both ends of the drum are respectively placed inside the two placement slots. A rotating rod is rotatably installed at the end of the rotating frame near the two placement slots. A screw is installed at the end of the rotating rod away from the rotating part. A notch adapted to the diameter of the screw is opened at the end of the rotating frame. A nut is threaded through the notch at the end of the screw away from the rotating rod.

[0009] Optionally, the guiding mechanism includes first slide grooves opened on the outer walls of both sides of the fixed frame, a first slider installed inside each of the two first slide grooves, an mounting block installed at the end of each of the two first sliders away from the first slide grooves, and a first rotating block rotatably installed at the end of each of the two mounting blocks away from the first sliders.

[0010] Optionally, a first electric telescopic rod is installed on one side of the outer wall of each of the two first rotating blocks, and a connecting rod is installed at the telescopic end of each of the two first electric telescopic rods. A rectangular plate is installed at the end of the two connecting rods that are close to each other, and a cavity is opened inside the rectangular plate.

[0011] Optionally, the inner wall of the rectangular plate is provided with four third sliding grooves that communicate with the cavity. Each of the four third sliding grooves is equipped with a third slider. The end of each of the four third sliders away from the third sliding groove is equipped with a moving block. The upper and lower ends of the moving block are equipped with second electric telescopic rods. The telescopic ends of the two second electric telescopic rods pass through the moving block and are connected to clamps.

[0012] Optionally, the bulldozing mechanism includes second sliding grooves opened on the outer walls of both sides of the fixed frame, with second sliders installed inside each of the two second sliding grooves, and rotating seats rotatably installed at the ends of the two second sliders away from the second sliding grooves, with second rotating blocks rotatably installed inside each of the two rotating seats.

[0013] Optionally, a third electric telescopic rod is installed at the end of each of the two second rotating blocks away from the rotating seat. A sleeve plate is installed at the telescopic end of each of the two third electric telescopic rods. A push plate is slidably installed inside the sleeve plate. Two fourth electric telescopic rods are installed on the outer walls of both sides of the sleeve plate. The telescopic ends of the two fourth electric telescopic rods are connected to the push plate.

[0014] Optionally, the push plate is hollow inside, with multiple drainage holes at the bottom end of the push plate, and a cover plate for sealing the multiple drainage holes is rotatably installed at the bottom end of the push plate. A connector is provided at the top end of the push plate, and a flexible hose is installed inside the connector. A water tank is pre-installed inside the device body, and the end of the flexible hose away from the connector extends into the water tank.

[0015] The beneficial effects of this invention are reflected in:

[0016] 1. In this invention, when the device body is seeding the paper strip, if there is wind, the set bulldozing mechanism can push some soil into the trench to pre-bury the paper strip placed in the trench and press and limit the paper strip, so as to avoid the problem of strong winds in the external environment blowing the paper strip out of the trench and improve the effect of the device body seeding the paper strip in windy weather.

[0017] 2. In this invention, if the field to be sown is relatively dry, after the paper tape enters the trench, the third drive device preset inside the two second rotating blocks is controlled to drive the two third electric telescopic rods to rotate and adjust, so that the two sleeve plates drive the bottom of the push plate to rotate in the same direction. After ensuring that the bottom of the two push plates faces the trench, the two cover plates are controlled to rotate outward and open, and the water supply mechanism inside the device body is activated to transport water from the water tank inside the device body to the inside of the two hoses, and discharge it outward into the trench through multiple drainage holes at the bottom of the two push plates. This pre-wets the paper tape placed inside the trench, ensuring that the paper tape can dissolve or degrade within a specified time, so that the seeds and fertilizer inside the paper tape can come into contact with the soil, facilitating the normal germination and growth of the seeds in the field.

[0018] 3. In this invention, if the paper strip breaks during the sowing process, in order to ensure that the spacing of subsequent seeds after germination is the same, the broken paper strip needs to be repaired and connected. After the workers use adhesive to glue the broken paper strip together, the repaired part can be placed between two clamps, and the extension ends of the two second electric telescopic rods can be extended to drive the two clamps to press the repaired part for a few minutes, so that the repaired part of the paper strip can be well glued and restored, thus improving the repair effect of the paper strip.

[0019] 4. In this invention, the guiding mechanism automatically rotates the paper strip to be sown downwards and guides it to the tail end of the device body, eliminating the need for manual traction of the paper strip and improving the efficiency of the device body in preparing the paper strip for sowing. Furthermore, by moving the moving block back and forth inside the rectangular plate, the moving block and the paper strip move back and forth synchronously and adaptively, avoiding friction and large deformation between the paper strip and the inner wall of the moving block during the process of passing through the moving block. This ensures that the paper strip has a good protective effect on the seeds and fertilizer wrapped inside, thereby indirectly improving the survival rate of the seeds after sowing in the field.

[0032] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0033] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0034] like Figures 1-10 As shown, a strip-shaped wrapping reel-type seed and fertilizer integrated sowing device includes a device body 1. A fixed frame 4 is installed on the top of the device body 1. A rotating frame 5 is rotatably installed inside the fixed frame 4. Four rollers 6 are installed inside the rotating frame 5 through four sets of limiting mechanisms. The surface of each of the four rollers 6 is wound with a paper strip containing seed and fertilizer. A guide wheel 8 is rotatably installed at the bottom of the fixed frame 4 to guide the unfolded paper strip downward. The fixed frame 4 also has a guiding mechanism inside to drive the paper strip to be quickly discharged into the trench. Both sides of the outer wall of the fixed frame 4 are provided with a soil-pushing mechanism to push some soil into the trench and limit the paper strip.

[0035] As a technical optimization of the present invention, a connecting part 2 is provided at the front end of the device body 1, and two movable wheels 3 are installed at both ends of the bottom of the device body 1. A fixing plate 10 is installed at the bottom of the tail end of the device body 1. A furrow opener 11 is rotatably installed inside the fixing plate 10. A first drive motor 12 with its output end connected to the rotating part of the furrow opener 11 is installed on one side of the outer wall of the fixing plate 10. When in use, the device body 1 can be connected to the connecting part 2 by means of a pull rope, and the other end of the pull rope can be connected to an agricultural tractor or other movable mechanical equipment to facilitate the movement of the device body 1 back and forth in the sowing area. During the movement of the device body 1 by means of multiple movable wheels 3, the first drive motor 12 is controlled to drive the furrow opener 11 to rotate at high speed, opening a furrow of a certain width in the soil of the sowing area so that the subsequent paper tape can be placed in the furrow.

[0036] As a technical optimization of the present invention, a second drive motor 13 is installed on one outer wall of the fixed frame 4, and the output end of the second drive motor 13 is connected to the rotating part of one end of the rotating frame 5. After the second drive motor 13 is started, it can drive the rotating frame 5 to rotate and adjust inside the fixed frame 4, and in turn drive the multiple drums 6 installed on the rotating frame 5 to rotate and adjust synchronously.

[0037] As a technical optimization of the present invention, the limiting mechanism includes two placement slots 17 opened on the rotating frame 5. The fixed shafts at both ends of the drum 6 are respectively placed inside the two placement slots 17. Rotating rods 18 are rotatably installed at the ends of the rotating frame 5 near the two placement slots 17. A screw 19 is installed at the end of the rotating rod 18 away from the rotating part. A notch 21 adapted to the diameter of the screw 19 is opened at the end of the rotating frame 5. A nut 20 is threaded through the notch 21 at the end of the screw 19 away from the rotating rod 18. When the roll 6 needs to be installed inside the rotating frame 5, first rotate the two corresponding rotating rods 18 outward to a position away from the placement slot 17. Then, place the fixed shafts at both ends of the roll 6 into the two placement slots 17 respectively. Then rotate the two rotating rods 18 back to their original positions so that the screws 19 at one end of the two rotating rods 18 enter the corresponding notches 21 respectively. Finally, thread the nut 20 onto the surface of the screw 19 to limit and fix the position of the rotating rod 18 at this time, thereby limiting and fixing the roll 6 installed inside the two placement slots 17. This makes it easier for the roll 6 to rotate inside the rotating frame 5, so that the paper strip on its surface can be unrolled and planted in the field.

[0038] As a technical optimization of the present invention, the guiding mechanism includes first slide grooves 15 opened on the outer walls of both sides of the fixed frame 4. First sliders 22 are installed inside each of the two first slide grooves 15. Mounting blocks 23 are installed at the ends of the two first sliders 22 away from the first slide grooves 15. First rotating blocks 24 are rotatably mounted at the ends of the two mounting blocks 23 away from the first sliders 22. First linear motors are pre-installed inside each of the two first slide grooves 15. The two first linear motors can drive the two first sliders 22 to move up and down inside the corresponding first slide grooves 15, thereby driving the two mounting blocks 23 and the first rotating blocks 24 to move up and down together on the outer walls of both sides of the fixed frame 4 for adjustment. First driving devices are pre-installed inside each of the two mounting blocks 23. The output ends of the two first driving devices are respectively connected to the rotating parts of the two first rotating blocks 24, thereby enabling the two first rotating blocks 24 to rotate for adjustment.

[0039] As a technical optimization of the present invention, a first electric telescopic rod 25 is installed on one outer wall of each of the two first rotating blocks 24. A connecting rod 26 is installed at the telescopic end of each of the two first electric telescopic rods 25. A rectangular plate 7 is installed at the adjacent end of the two connecting rods 26. A cavity 27 is opened inside the rectangular plate 7. During the telescopic process, the telescopic ends of the two first electric telescopic rods 25 can drive the two connecting rods 26 and the rectangular plate 7 to move and adjust together.

[0040] As a technical optimization of the present invention, the inner wall of the rectangular plate 7 is provided with four third sliding grooves 28 that communicate with the cavity 27. Each of the four third sliding grooves 28 has a third slider 30 installed inside. A moving block 29 is installed at one end of each of the four third sliders 30 away from the third sliding groove 28. A second electric telescopic rod 32 is installed at both the upper and lower ends of the moving block 29. The telescopic ends of the two second electric telescopic rods 32 pass through the moving block 29 and are connected to clamping plates 31. A third linear motor is pre-installed inside each of the four third sliding grooves 28. The four third linear motors can drive the four third sliders 30 to move back and forth within their respective third sliding grooves 28, thereby causing the moving block 29 to move back and forth within the cavity 27 for adjustment. During the telescopic process of the two second electric telescopic rods 32, the telescopic ends can drive the corresponding clamping plates 31 to adjust together within the moving block 29. After the two clamping plates 31 move towards each other, the paper tape passing through the moving block 29 can be clamped and fixed by the two clamping plates 31.

[0041] As a technical optimization of the present invention, the bulldozing mechanism includes second sliding grooves 16 opened on the outer walls of both sides of the fixed frame 4. A second slider 33 is installed inside each of the two second sliding grooves 16. A rotating seat 34 is rotatably installed at the end of each of the two second sliders 33 away from the second sliding groove 16. A second rotating block 35 is rotatably installed inside each of the two rotating seats 34. A second linear motor is pre-installed inside each of the two second sliding grooves 16. The two second linear motors can drive the two second sliders 33 to move up and down inside the corresponding second sliding grooves 16, thereby driving the two rotating seats 34 and the second rotating blocks 35 to move up and down synchronously on the outer walls of both sides of the fixed frame 4. A second driving device is pre-installed inside each of the two second sliders 33. The output ends of the two second driving devices are respectively connected to the rotating parts of the two rotating seats 34, thereby driving the two rotating seats 34 to rotate and adjust. A third driving device is pre-installed on one side of the outer wall of each of the two rotating seats 34. The output ends of the two third driving devices are respectively connected to the rotating parts of one end of the two second rotating blocks 35, thereby driving the two second rotating blocks 35 to rotate and adjust inside the corresponding rotating seats 34.

[0042] As a technical optimization of the present invention, a third electric telescopic rod 36 is installed at the end of each of the two second rotating blocks 35 away from the rotating seat 34. A sleeve plate 37 is installed at the telescopic end of each of the two third electric telescopic rods 36. A push plate 9 is slidably installed inside the sleeve plate 37. Two fourth electric telescopic rods 41 are installed on the outer walls of both sides of the sleeve plate 37, and the telescopic ends of the two fourth electric telescopic rods 41 are connected to the push plate 9. During the telescopic process of the two third electric telescopic rods 36, they can drive the two sleeve plates 37 and the push plate 9 to move and adjust together; during the telescopic process of the multiple fourth electric telescopic rods 41, they can drive the push plate 9 to move up and down inside the sleeve plate 37 for adjustment.

[0043] As a technical optimization of the present invention, the push plate 9 is hollow inside, and multiple drainage holes 38 are opened at the bottom end of the push plate 9. A cover plate 39 for sealing the multiple drainage holes 38 is rotatably installed at the bottom end of the push plate 9. A connector 40 is provided at the top end of the push plate 9, and a flexible hose 14 is installed inside the connector 40. A water tank is pre-installed inside the device body 1, and the end of the flexible hose 14 away from the connector 40 extends into the water tank. The water tank pre-installed inside the device body 1 can transport water to the interior of the two push plates 9 through the two flexible hoses 14 respectively, and discharge it outward through the multiple drainage holes 38. A driving device is pre-installed on one side of the outer wall of each of the two push plates 9. The output end of the two driving devices is connected to the rotating part of one end of each of the two cover plates 39, thereby driving the two cover plates 39 to rotate and adjust at the bottom of the corresponding push plate 9.

[0044] In this invention, before the user uses the device, the rotating frame 5 has not yet installed multiple rolls 6. At this time, two rotating rods 18 can be driven to rotate and open away from the placement slots 17. Then, the fixed shafts at both ends of one of the rolls 6 are placed inside the two placement slots 17 respectively. Then, the two rotating rods 18 are rotated back to their original positions, so that the screws 19 at one end of the two rotating rods 18 enter the corresponding notches 21 respectively. Finally, the nuts 20 are threaded onto the surface of the screws 19 to limit and fix the position of the rotating rods 18. This completes the installation of one roll 6. Subsequent rolls 6 can be adjusted by rotating the rotating frame 5 by 90 degrees through the second drive motor 13, so that the installation part of the next roll 6 on the rotating frame 5 rotates to the top. Repeating the above steps completes the installation and fixing of subsequent rolls 6, waiting for the subsequent sowing work to begin.

[0045] After multiple rolls 6 with paper tape wound on their surfaces are sequentially installed inside the rotating frame 5, the agricultural tractor can be connected and fixed to the connecting part 2 using a pull rope. Then, the paper tape end of one of the rolls 6 closest to the device body 1 is manually pulled and placed inside the moving block 29, positioned between the two clamping plates 31. The telescopic ends of the two second electric telescopic rods 32 are then extended together, causing the two clamping plates 31 to clamp and fix the paper tape end. After ensuring that the moving block 29 is centered inside the cavity 27, the two first sliders 22 are moved together in the corresponding first slide grooves 15 towards the device body 1. Then, the two first rotating rods are controlled to extend together. The moving block 24 drives the corresponding first electric telescopic rod 25 and the rectangular plate 7 to rotate downward together. At this time, the telescopic ends of the two first electric telescopic rods 25 can be controlled to extend and retract adaptively, and the two first sliders 22 can be controlled to move and adjust adaptively inside the corresponding first slide groove 15, so that the rectangular plate 7 rotates counterclockwise from the bottom of the fixed frame 4 to the bottom of the roll 6. As the rectangular plate 7 rotates and adjusts, it can drive the paper strip held and fixed by the two clamping plates 31 to unfold downward and pull it to the bottom of the roll 6. This allows the guiding mechanism to automatically rotate and guide the paper strip to be sown downward to the tail end of the device body 1 without manual pulling of the paper strip, thus improving the efficiency of the device body 1 in preparing for the sowing of the paper strip.

[0046] After the guiding mechanism unfolds the paper tape and moves it to the position below the roll 6, the telescopic ends of the two second electric telescopic rods 32 are retracted together, causing the two clamping plates 31 to release their clamping and fixing of the paper tape. The operator can then manually remove the end of the paper tape. After the limit is reached, the two first electric telescopic rods 25 and the first slider 22 are controlled to rotate and move back to their original positions, causing the rectangular plate 7 to return to its original position. At this time, the paper tape is still located between the two clamping plates 31, and the downward-unfolded section of the paper tape can be manually pulled, causing the paper tape to contact the guide wheel 8. The outer walls overlap, and the first drive motor 12 drives the furrow opener 11 to rotate. As the agricultural tractor moves forward in the field, the furrow opener 11 can open furrows at designated locations in the field. The workers can place the end of the paper strip inside the furrow and press the paper strip inside the furrow with relevant tools or stones. Then, the movement of the device body 1 causes the paper strip on the surface of the roll 6 to slowly unfold downwards and be placed inside the furrow opened by the furrow opener 11, thus achieving the effect of automatically sowing the paper strip filled with fertilizer and seeds.

[0047] Since the paper tape is uniformly wound on the surface of the roll 6, in order to ensure that the paper tape avoids large-area friction with the inner wall of the moving block 29 as it continuously unfolds downwards, which could cause wear on the paper tape surface and leakage of the seeds and fertilizer inside the paper tape, the extension ends of the two second electric telescopic rods 32 can be controlled to extend together as the paper tape continuously passes between the two clamps 31. This causes the two clamps 31 to abut against the upper and lower sides of the paper tape, but not to clamp it tightly. According to the position of the paper tape unfolding from the surface of the roll 6, the four third sliders 30 are controlled to move back and forth in the corresponding third slide grooves 28, causing the moving block 29 and the paper tape to move back and forth synchronously and adaptively. This avoids friction and large deformation between the paper tape and the inner wall of the moving block 29 as it passes through the moving block 29, ensuring that the paper tape has a good protective effect on the seeds and fertilizer inside, thereby indirectly improving the survival rate of the seeds after sowing in the field.

[0048] If there is wind during the use of the device body 1, in order to prevent the paper tape placed inside the groove from being blown out, Figure 1 As shown, the extension ends of multiple fourth electric telescopic rods 41 on the outer walls of the control frame 4 retract downwards, causing two push plates 9 to extend downwards inside the corresponding sleeves 37 until they contact the field. After the paper strip is placed inside the trench, the control of two second rotating blocks 35 to rotate in the direction closer to the control frame 4 inside the corresponding rotating seats 34 drives the two push plates 9 to push part of the soil dug out by the trench opener 11 into the trench, pre-burying the paper strip placed inside the trench and pressing and limiting the paper strip, avoiding the problem of strong winds in the external environment blowing the paper strip out of the trench, and improving the effect of the device body 1 on the paper strip sowing in windy weather.

[0049] If the field to be sown is relatively dry, the soluble material on the surface of the sowing tape may not dissolve quickly after sowing, preventing the seeds and fertilizer inside the tape from contacting the soil within the specified time. In this case, after the tape enters the furrow, if... Figure 1 As shown, the preset third drive device inside the two second rotating blocks 35 drives the two third electric telescopic rods 36 to rotate and adjust, so that the two sleeve plates 37 drive the bottom of the push plate 9 to rotate in the same direction. After ensuring that the bottom of the two push plates 9 faces the trench, the two cover plates 39 are controlled to rotate outward and open, and the water supply mechanism inside the device body 1 is activated to transport the water in the water tank inside the device body 1 to the inside of the two hoses 14, and discharge it outward into the trench through the multiple drainage holes 38 at the bottom of the two push plates 9. This pre-wets the paper tape placed inside the trench, ensuring that the paper tape can dissolve or degrade within a specified time, so that the seeds and fertilizer inside the paper tape can come into contact with the soil, which is convenient for the seeds to germinate and grow normally in the field.

[0050] If the paper strip breaks during the sowing process, in order to ensure that the spacing of subsequent seeds is the same after germination, the broken paper strip needs to be repaired and connected. After the staff uses adhesive to glue the broken paper strip together, the repaired part can be placed between two clamps 31, and the extension ends of the two second electric telescopic rods 32 are used to extend and drive the two clamps 31 to press the repaired part for a few minutes, so that the repaired part of the paper strip can be well glued and restored, thus improving the repair effect of the paper strip.

[0051] Meanwhile, in order to test the connection strength of the repaired paper tape, the telescopic ends of the two second electric telescopic rods 32 are controlled to retract together, causing the two clamping plates 31 to release the pressure and fixation on the repaired part. Then, the operator can manually drive the drum 6 to rotate, moving the repaired part of the paper tape between the drum 6 and the rectangular plate 7. Then, the telescopic ends of the two second electric telescopic rods 32 are controlled to extend together, causing the two clamping plates 31 to clamp and fix the paper tape. The drum 6 is manually limited to prevent it from rotating further. Then, the telescopic ends of the two first electric telescopic rods 25 are controlled to extend together, pushing the rectangular plate 7 towards the direction closer to the device body 1. This allows the two clamping plates 31 to pull the clamped paper tape, achieving the effect of automatically testing the connection strength of the repaired paper tape and avoiding the problem of secondary breakage due to the paper tape's failure to meet the strength standard after repair.

[0052] After the device body 1 sows the paper tape wound on the surface of one of the rolls 6, it can control the second drive motor 13 to drive the rotating frame 5 to rotate, so that the next roll 6 rotates to a position close to the rectangular plate 7, and repeat the above steps to guide the new paper tape downward and automatically sow it into the groove, so as to realize the effect of continuous paper tape sowing by the device body 1 and improve the efficiency of paper tape sowing.

[0053] After the device body 1 is used, if there is still water in the water tank, the telescopic ends of the two first electric telescopic rods 25 can be extended together to push the rectangular plate 7 to a position close to the device body 1. With the rotation of the two first rotating blocks 24, the rectangular plate 7 is driven to rotate downward to a position close to the trencher 11. Then, the two rotating seats 34 are controlled to drive the third electric telescopic rod 36 and the push plate 9 to rotate and adjust. The third drive device inside the two second rotating blocks 35 is controlled to drive the third electric telescopic rod 36 and the sleeve plate 37 to rotate and adjust. This causes the multiple drainage holes 38 of the two push plates 9 to spray water toward the trencher 11 and the rectangular plate 7, automatically washing away the mud on the surface of the trencher 11 and the fertilizer powder attached to the inner wall of the moving block 29, achieving a self-cleaning effect for these two components and reducing the difficulty of cleaning these two components in the future.
