Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a potato planting device. Background Technology

[0002] Potatoes, also known as spuds, are the tubers of a perennial herbaceous plant belonging to the nightshade family (Solanaceae). They originated in the Andes Mountains of South America. Rich in starch, protein, vitamin C, B vitamins, and minerals such as potassium, phosphorus, and calcium, potatoes are one of the world's most important food crops. They can be eaten as a staple food or processed into various products such as starch, potato chips, and French fries, playing a vital role in agricultural production and people's daily diet.

[0003] Currently, there are two mulch film cultivation techniques in potato planting: planting before mulching and mulching before planting. Among them, mulching before planting has advantages over planting before mulching, such as increasing soil temperature, uniform seedling emergence, weed control and moisture retention, prevention of green potatoes, and better mulching effect, resulting in significant comprehensive benefits. However, during the planting process, farmers need to squat on the ridges and dig holes in the mulch film to place the potato planting blocks. This method is not only inefficient, but also prone to causing the mulch film on both sides of the ridge to lift when making holes in the middle of the ridge, thus affecting the mulch film's heat retention effect on the ridge. Therefore, this invention provides a potato planting device to meet the needs. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a potato planting device that, through the setting of a sowing component, can not only quickly complete the cutting of mulch film and dig holes that meet the planting depth requirements of potato planting blocks, but also automatically cover the potato planting blocks with soil after placement, effectively improving farmers' planting efficiency. Simultaneously, the device can adapt to the width and height of ridges in different fields, ensuring that the depth of the cutting and digging planting holes meets the appropriate standards for potato planting. Furthermore, the device can automatically clean the cutting tools on the sowing component, preventing soil adhering to the tools from damaging the mulch film during subsequent cuttings and affecting its heat preservation effect, thus solving problems such as low planting efficiency and reduced mulch film heat preservation for farmers.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above solution, by setting up a planting component, not only can the mulch film be cut quickly and holes dug to meet the planting depth requirements of potato planting blocks be dug, but the soil can also be automatically covered after the potato planting blocks are placed, effectively improving the planting efficiency of farmers. At the same time, the equipment can be adapted to the width and height of the ridges in different fields to ensure that the depth of the planting holes dug out meets the appropriate standards for potato planting. In addition, the equipment can also automatically clean the cutting tools on the planting component to prevent the soil adhering to the tools from damaging the mulch film during the next cutting of the mulch film and affecting its heat preservation effect.

[0015] By setting it inside the sowing assembly, not only can the distance between the square cylinder and the top of the ridge be maintained at a certain distance, creating favorable conditions for subsequent cutting of the mulch film on the top of the ridge, but the distance between the two sliding cylinders can also be adjusted according to the width of the ridge to adapt to the differences in the width of the ridges built in different fields.

[0016] By incorporating a feature within the planting assembly, the square cylinder can be slid by the drive mechanism on this device, eliminating the need for additional power support and reducing production costs. Furthermore, the sliding distance of the square cylinder can be adjusted according to the height of different ridges, maintaining a certain distance between the square cylinder and the top of the ridge. This ensures that the subsequent cutting depth of the ridge remains within the optimal planting depth range for potato planting blocks.

[0017] By setting it inside the planting assembly, not only can the mulch film be cut, but the soil in the second chamber can also be blocked by the third baffle. At the same time, potato planting blocks are placed into the holes cut by the cutting box, and then the potato planting blocks are covered with soil. This process improves the planting efficiency of farmers. In addition, the inner wall of the cutting box can be scraped to remove the soil adhering to it, so as not to affect the operation of the next hole.

[0018] By incorporating the planting assembly, the cutting box can be easily and quickly inserted into the ridges by pressing the end of the lever away from the first rotating handle; the cutting depth can also be adjusted according to the height of the ridges to meet the standards suitable for potato planting.

[0038] The potato planting equipment provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0039] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0040] like Figures 1 to 15As shown, an embodiment of the present invention provides a potato planting device, including a fixed frame 102. A traction rod 103 and a pallet 104 are respectively installed on both sides of the fixed frame 102. The traction rod 103 is used to tow the device to a tractor, while the pallet 104 is used to support the farmer, allowing him to follow and assist in operating the device. A seed box 101 and a conveying device 1 are respectively installed in the middle of the fixed frame 102. The seed box 101 is located in the middle of the fixed frame 102 near the pallet 104 and is used to hold potato planting blocks, forming a funnel shape. The conveying device 1 is located on the fixed frame. On the side of the body 102 near the traction rod 103, the conveying device 1 is used to convey potato planting blocks. A drive device 106 is installed near the bottom of the fixed frame 102. The linkage rod 105 on the drive device 106 is linked with the conveying device 1. The drive device 106 can drive the conveying device 1 to convey the potato planting blocks. The fixed frame 102, the conveying device 1, the seed box 101 and the drive device 106 are all existing technologies and will not be described in detail. The sowing component is used to automatically plant potatoes on the ridges. The sowing component is connected to the conveying device 1.

[0041] This application, by setting up a planting component, can not only quickly complete the cutting of mulch film and dig holes that meet the planting depth requirements of potato planting blocks, but also automatically cover the potato planting blocks with soil after placement, effectively improving farmers' planting efficiency. At the same time, the equipment can be adapted to the width and height of the ridges in different fields to ensure that the depth of the cutting and digging planting holes meets the appropriate standards for potato planting. In addition, the equipment can automatically clean the cutting tools on the planting component to prevent the soil adhering to the tools from damaging the mulch film during the next cutting of the mulch film and affecting its heat preservation effect.

[0042] In this embodiment, as Figures 2 to 4 and Figures 8 to 11As shown, the sowing assembly includes a connecting circular plate 2 fixedly connected to the bottom of the conveying device 1. The connecting circular plate 2 is a hollow metal circular plate. Several sliding columns 203 arranged in a circumferential array are fixedly connected to the bottom outer wall of the connecting circular plate 2. Each sliding column 203 consists of a metal cylinder and a metal sphere. The metal sphere is fixedly connected to the end of the metal cylinder away from the connecting circular plate 2. A first sliding plate 202 is slidably connected to the outer wall of the sliding column 203. The first sliding plate 202 is a square metal plate. Several second clearance holes arranged in a circumferential array are provided on the top outer wall of the first sliding plate 202. There are four second clearance holes in total. Each second clearance hole is a circular groove, and the inner wall contour of the second clearance hole is similar to the outer wall contour of the sliding column 203. The first sliding plate 202 can slide on the outer wall of the sliding column 203. A tension spring 201, made of metal, is fitted onto the outer wall of the sliding column 203. When the tension spring 201 is subjected to force, it deforms along its bending direction. The tension spring 201 is existing technology and will not be described in detail. One end of the tension spring 201 is fixedly connected to the bottom outer wall of the connecting circular plate 2, and the other end is fixedly connected to the top outer wall of the first sliding plate 202. When the first sliding plate 202 is subjected to force and slides away from the connecting circular plate 2 along the outer wall of the sliding column 203, the tension spring 201 will be subjected to force and deform along its bending direction. When the first sliding plate 202 is no longer subjected to force, the tension spring 201 will return to its elasticity. Under the action of the force, the first sliding plate 202 recovers its deformation and provides a certain pulling force when it slides along the outer wall of the sliding column 203 towards the connecting circular plate 2. The diameter of the metal ball on the sliding column 203 is larger than the diameter of the second clearance hole on the first sliding plate 202, which can prevent the first sliding plate 202 from sliding off the outer wall of the sliding column 203 when it slides on the sliding column 203. A square cylinder 204 is fixedly connected to the bottom outer wall of the first sliding plate 202. The square cylinder 204 is a hollow metal cuboid. A first clearance groove 206 is opened in the middle of the outer wall of the square cylinder 204 near the traction rod 103. The first clearance groove 206 is a rectangular groove with arcs at both ends. A U-shaped groove is fixedly connected to the outer wall of the square cylinder 204 near the bottom end of the first clearance groove 206. The U-shaped cylinder 205 is a U-shaped metal cylinder. A square cylinder 204 has symmetrically arranged first sliding grooves 207 on both sides. Each first sliding groove 207 is a rectangular groove. First support columns 209 are symmetrically fixed to the outer walls of the square cylinder 204 near the bottom of the first sliding grooves 207. Each first support column 209 is a square metal column. A sliding cylinder 4 is slidably connected to the outer wall of the first support column 209. The sliding cylinder 4 consists of a hollow metal cuboid at the bottom and a metal cylinder at the top. The inner contour of the sliding cylinder 4 matches the outer contour of the first support column 209, allowing the sliding cylinder 4 to slide on the outer wall of the first support column 209. A second threaded hole 404 is provided on the top outer wall of the sliding cylinder 4.The second threaded hole 404 is a circular groove with threads on its inner wall, and it is connected to the inner wall of the sliding cylinder 4. A second rotating handle 403 is screwed onto the inner wall of the second threaded hole 404. The second rotating handle 403 consists of two parts: a metal cylinder with an anti-slip groove on its outer wall at the top and a metal cylinder with a threaded groove at the bottom. This arrangement allows the two sliding cylinders 4 to slide separately according to the width of the ridge. The two sliding cylinders 4 slide along the outer walls of the two first support columns 209 until the distance between the two sliding cylinders 4 is just right for the ridge. To fix the width, rotate the second handle 403 clockwise, causing it to screw into the inner wall of the second threaded hole 404 towards the bottom inner wall of the sliding cylinder 4, until the bottom end of the second handle 403 touches the top outer wall of the first support column 209. The sliding cylinder 4 can then be fixed in place. A second support column 401, a square metal column, is fixedly connected to the bottom outer wall of the sliding cylinder 4. An elastic base plate 402, a "U"-shaped metal plate, is fixedly connected to the outer wall of the second support column 401 near its bottom end. When the elastic base plate 402 is subjected to force, it deforms along its bending direction. When the first sliding plate 202 is subjected to force and slides along the outer wall of the sliding column 203 away from the connecting circular plate 2, the square cylinder 204 will drive the first support column 209 to move along with the first sliding plate 202. The sliding cylinder 4 will also move along with the first support column 209, and drive the second support column 401 and the elastic base plate 402 to move. During the movement of the elastic base plate 402, the outer wall of the end away from the second support column 401 will abut against the drainage ditch between the ridges. As the second support column 401 moves, the elastic base plate 402 is subjected to force and deforms along the bending direction. The end of the elastic base plate 402 furthest from the second support column 401, under its own elasticity, continuously presses against both sides of the plastic film on the ridge. The plastic film is then straightened under the force. This structural design not only maintains a certain distance between the square cylinder 204 and the top of the ridge, creating favorable conditions for subsequent cutting of the plastic film at the top of the ridge, but also allows adjustment of the distance between the two sliding cylinders 4 according to the width of the ridge, adapting to the differences in the width of the ridges built in different fields.

[0043] In this embodiment, as Figures 1 to 7As shown, the sowing assembly also includes a rotating cylinder 301 fixedly connected to the bottom of the fixed frame 102. The rotating cylinder 301 is a metal cylinder. A first gear 302 is installed on the outer wall of the end of the rotating cylinder 301 away from the fixed frame 102. A second gear 3 meshes with the first gear 302. Both the first gear 302 and the second gear 3 are made of metal, and both the first gear 302 and the second gear 3 are existing technologies, so they will not be described in detail. The second gear 3 is installed on the connecting rod 105 on the drive device 106. As the drive device 106 rotates, it drives the second gear 3 to rotate. A rotating disk 303 is fixedly connected to the outer wall of the first gear 302 near the square cylinder 204. The rotating disk 303 is a metal disk. The outer wall of 303 has several fifth clearance holes 304 arranged in a linear array. Each fifth clearance hole 304 is a circular groove. A pull plate 305 is fixedly connected to the inner wall of the fifth clearance hole 304 by screws. The pull plate 305 is a rectangular metal plate with arc ends. Sixth clearance holes 307 and seventh clearance holes 306 are respectively opened on the outer wall of the pull plate 305 near both ends. The sixth clearance hole 307 is a circular groove, and the inner wall contour of the sixth clearance hole 307 is circular, just like the inner wall contour of the fifth clearance hole 304. As needed, the pull plate 305 can be installed at different positions of the sixth clearance holes 307 on the rotating disk 303 by screws. A fixed cylinder 208 is rotatably connected to the inner wall of the seventh clearance hole 306. The column 208 consists of two parts: a metal cylinder and a metal circular plate. The inner wall contour of the seventh clearance hole 306 matches the outer wall contour of the cylindrical part of the fixed column 208, so the pulling plate 305 can rotate on the fixed column 208. The end of the fixed column 208 away from the pulling plate 305 is fixedly connected to the outer wall of the square cylinder 204 near the top of the first sliding groove 207. When the device travels on the ridge, the drive device 106 rotates and drives the second gear 3 to rotate. The second gear 3 then drives the first gear 302 to rotate. The first gear 302 drives the rotating disk 303 to rotate. As the rotating disk 303 rotates, the pulling plate 305 rotates and moves accordingly, thereby pulling the fixed column 208 to move. 08 drives the square cylinder 204 to reciprocate along the outer wall of the sliding column 203. When the square cylinder 204 slides towards the bottom along the outer wall of the sliding column 203, the tension spring 201 is stressed and deforms along its bending direction. When the square cylinder 204 slides towards the top along the outer wall of the sliding column 203, the tension spring 201 is no longer stressed and returns to its bending direction. If the ridge is too high, to maintain a certain distance between the square cylinder 204 and the top of the ridge during the rotation of the rotating disk 303, the pulling plate 305 can be fixedly connected to the fifth clearance hole 304 closer to the center of the rotating disk 303 by screws. With the above structural configuration, the square cylinder 204 can be driven to slide by the drive device 106 on this device without the need for additional power support, thus reducing production costs.The sliding distance of the square cylinder 204 can be adjusted according to the height of different ridges, maintaining a certain distance between the square cylinder 204 and the top of the ridge. This ensures that the subsequent cutting depth of the ridge remains within the optimal planting depth range for potato tubers.

[0044] In this embodiment, as Figures 8 to 14As shown, a cutting box 5 is slidably connected to the inner wall of the square cylinder 204. The cutting box 5 is a hollow metal cylinder with an inclined surface on one side of its bottom end. The inclined surface of the cutting box 5 is located on the outer wall of the bottom end near the first clearance groove 206. A first pull cable 7 is fixedly connected to the outer wall of the cutting box 5 near the first clearance groove 206. The first pull cable 7 is made of metal and is a prior art technology, so it will not be described in detail. By pulling the first pull cable 7, the cutting box 5 can be slid along the inner wall of the square cylinder 204 towards its bottom. A second clearance groove 503 is provided on the outer wall of the cutting box 5 away from the first clearance groove 206. The second clearance groove 503 is a "convex" shaped groove. The cutting box 5 is respectively located near the two first sliding grooves. A second sliding plate 501 is symmetrically fixedly connected to the outer walls of both sides of the groove 207. The second sliding plate 501 is a metal plate with an arc at one end. The outer contour of the second sliding plate 501 matches the inner contour of the first sliding groove 207, so the second sliding plate 501 can slide on the inner wall of the first sliding groove 207. One end of a spring 502 is fixedly connected to the bottom outer wall of the second sliding plate 501. The other end of the spring 502 is fixedly connected to the top outer wall of the first support column 209. The spring 502 is a prior art and will not be described in detail. When the spring 502 is subjected to force, it will deform along its bending direction. A first baffle 504 and a second baffle 505 are fixedly connected to the inner wall of the cutting box 5. The first baffle 504 and the second baffle 505... Both baffles 505 are metal plates, and the first baffle 504 is inclined toward the inner wall of the cutting box 5 where the second clearance groove 503 is provided. One end of a C-shaped elastic plate 506 is fixedly connected to the bottom of the second baffle 505. The C-shaped elastic plate 506 is a C-shaped metal plate that deforms along its bending direction when subjected to force. The other end of the C-shaped elastic plate 506 is fixedly connected to a third baffle 507. The third baffle 507 is a metal plate with an inclined surface at its bottom. The inclination angle of the inclined surface at its bottom is consistent with the inclination angle of the inclined inner wall of the cutting box 5, facilitating the contact between the bottom of the third baffle 507 and the inclined inner wall of the cutting box 5. The first baffle 504, the second baffle 505, and the C-shaped elastic plate... With the cooperation of baffle 506 and third baffle 507, the inner wall of the cutting box 5 can be divided into two chambers: a first chamber and a second chamber. The second chamber is located near the second clearance groove 503. A weakening groove 509 is provided on the outer wall of the C-shaped elastic plate 506 near the second clearance groove 503. The weakening groove 509 is an arc-shaped groove. The weakening groove 509 facilitates the C-shaped elastic plate 506 to deform better along its bending direction after being subjected to force. A second cable 6 is fixedly connected to the outer wall of the third baffle 507 near the second clearance groove 503. The second cable 6 is made of metal and is disclosed in the prior art, so it will not be described in detail. Since the outer wall contour of the second cable 6 matches the inner wall contour of the second clearance groove 503 near the top,Therefore, the second clearance groove 503 can avoid the second cable 6 when the cutting box 5 slides along the inner wall of the square cylinder 204. An L-shaped fixing post 601 is fixedly connected to the inner wall of the square cylinder 204 away from the first clearance groove 206. The L-shaped fixing post 601 is an "L"-shaped metal cylinder. The outer contour of the L-shaped fixing post 601 matches the inner wall contour of the second clearance groove 503 near the bottom. Therefore, the L-shaped fixing post 601 can slide on the inner wall of the second clearance groove 503 near the bottom. A baffle plate 602 is fixedly connected to the end of the L-shaped fixing post 601 away from the inner wall of the square cylinder 204. The baffle plate 602 is a square metal plate, and the outer contour of the baffle plate 602 matches the inner wall contour of the second chamber. Therefore, the barrier plate 602 can slide on the inner wall of the second chamber. A third clearance hole 603 is provided on the outer wall of the L-shaped fixing post 601 near the inner wall of the square cylinder 204. The third clearance hole 603 is a circular groove, and its inner wall contour matches the outer wall contour of the second cable 6. Therefore, the second cable 6 can slide on the inner wall of the third clearance hole 603. A fourth clearance hole 604 is provided on the top outer wall of the barrier plate 602. The fourth clearance hole 604 is a circular groove, and its inner wall contour matches the outer wall contour of the second cable 6. Therefore, the second cable 6 can slide on the inner wall of the fourth clearance hole 604. The third clearance hole 603 and the fourth clearance hole 604 are on the same vertical plane. On the front, the other end of the second cable 6 passes through the fourth clearance hole 604, the third clearance hole 603, and the second clearance groove 503 in sequence, and is fixedly connected to the middle of the inner wall of the square cylinder 204 near the second clearance groove 503. A chamfer 508 is provided on the outer wall of the bottom end of the cutting box 5, so that the bottom end of the cutting box 5 forms a square annular blade, which facilitates the subsequent cutting of the mulch film. A shovel plate 210 is fixedly connected to the inner wall of the square cylinder 204 near the bottom. The shovel plate 210 is an arc-shaped metal plate with one open end. There are four shovel plates 210, which are fixedly connected to the four inner walls of the square cylinder 204 near the bottom, forming an overall rectangular outline. When the cutting box 5 moves along the inner wall of the square cylinder 204 towards the square cylinder 204... When the bottom slides, the outer wall of the shovel plate 210 is squeezed by the outer wall of the cutting box 5, and deforms along its bending direction. As the cutting box 5 slides, the second sliding plate 501 slides along the inner wall of the first sliding groove 207 towards the bottom of the square cylinder 204. At this time, the spring 502 is stressed and deforms along its bending direction, and the cutting box 5 cuts into the ridge. Then, the second cable 6 pulls the third baffle 507 to tilt, causing the C-shaped elastic plate 506 to be stressed. With the cooperation of the weakening groove 509 on the C-shaped elastic plate 506, the C-shaped elastic plate 506 deforms along its bending direction. At this time, the third baffle 507 blocks the soil in the second chamber.The potato planting blocks, falling into the first chamber via the conveyor 1, are guided along the inclined inner wall of the cutting box 5 into the pre-cut holes. As the cutting box 5 slides towards the top of the square cylinder 204, the second sliding plate 501 follows the cutting box 5, sliding along the inner wall of the first sliding groove 207 towards the top of the square cylinder 204. The spring 502, no longer under stress, returns to its original shape along its bending direction, providing a certain thrust for the sliding of the second sliding plate 501. The second cable 6 is no longer taut, thus no longer putting stress on the third baffle 507. At this point, the C-shaped elastic plate 506, under its own elasticity, returns to its original shape, driving the third baffle 507... 7. Resetting allows the soil previously blocked by the third baffle 507 to fall into the cut holes, covering the potato planting blocks with soil. Simultaneously, as the cutting box 5 slides towards the top of the square cylinder 204, the baffle plate 602 scrapes away the soil adhering to the inner wall of the second chamber of the cutting box 5. This structural design not only cuts the mulch film but also blocks the soil in the second chamber via the third baffle 507, allowing the potato planting blocks to be placed into the cut holes in the cutting box 5 and then covered with soil. This process improves the farmer's planting efficiency. Furthermore, it scrapes away soil adhering to the inner wall of the cutting box 5, preventing interference with the operation of the next planting hole.

[0045] In this embodiment, as Figures 1 to 4 and Figure 15As shown, the sowing assembly also includes a semi-circular movable buckle 702 fixedly connected to the top of the conveying device 1. The semi-circular movable buckle 702 is a metal cuboid with an arc at the top and a groove. A pressure rod 701 is fixedly connected to the semi-circular movable buckle 702 by screws. The pressure rod 701 is an "S"-shaped metal cylinder. A first threaded hole 704 is formed on the outer wall of one end of the pressure rod 701. The first threaded hole 704 is a circular groove with threads on its inner wall. A first rotating handle 703 is screwed onto the inner wall of the first threaded hole 704. The first rotating handle 703 consists of a metal cylinder with an anti-slip groove at one end and a metal cylinder with a threaded groove at the other end. The device consists of two parts. The first handle 703 is a metal cylinder with a threaded groove, the outer contour of which matches the inner contour of the threaded groove. The pressure rod 701 has a first clearance hole 705 on its outer wall near the first screw end. The first clearance hole 705 is a circular groove, and its inner contour matches the outer contour of the first cable 7 mentioned above. Therefore, the other end of the first cable 7 passes through the first clearance groove 206, then around the outer wall of the U-shaped cylinder 205, and finally inserts into the first clearance hole 705. Then, the first handle 703 is rotated clockwise. The metal cylinder with the threaded groove on the first handle 703... The cylindrical part rotates along the inner wall of the first threaded hole 704 and moves towards the first clearance hole 705. The end of the first handle 703 near the first clearance hole 705 clamps the first cable 7, fixing it in place. When the end of the pressure rod 701 away from the first handle 703 is pressed, the end of the pressure rod 701 near the first handle 703 will lift under the lever principle, pulling the first cable 7. Since the first cable 7 passes around the outer wall of the U-shaped cylinder 205, pulling the first cable 7 will cause the cutting box 5 to move along the inner wall of the square cylinder 204 towards the bottom of the square cylinder 204. The plastic film can be cut. If the field ridges are low, in order to ensure that the cutting depth of the cutting box 5 meets the standard for potato planting, the length of the first cable 7 inserted into the first clearance hole 705 can be increased, the first handle 703 can be tightened to fix the first cable 7, and then the end of the pressure rod 701 away from the first handle 703 can be pressed to make the cutting depth of the cutting box 5 suitable for potato planting. The above structure not only allows the cutting box 5 to cut into the field ridge by pressing the end of the pressure rod 701 away from the first handle 703, making the operation simple and quick; but also allows the cutting depth of the cutting box 5 to be adjusted according to the height of the field ridges to meet the standard for potato planting.

[0046] The working principle of the technical solution provided by this invention is as follows:

[0047] In use, this device travels on the field ridges. The drive device 106 rotates and drives the second gear 3 to rotate. The second gear 3 then drives the first gear 302 to rotate. The first gear 302 drives the rotating disk 303 to rotate. As the rotating disk 303 rotates, the pull plate 305 follows its rotation and is displaced, which in turn pulls the fixed cylinder 208 to move. The fixed cylinder 208 drives the square cylinder 204 to move back and forth along the outer wall of the sliding column 203. When the square cylinder 204 slides to the bottom along the outer wall of the sliding column 203, the tension spring 201 is stressed and deforms along its bending direction. When the square cylinder 204 slides to the top along the outer wall of the sliding column 203, the tension spring 201 is no longer stressed and returns to its bending direction. If the field ridge is piled up too high, in order to keep the square cylinder 204 at a certain distance from the top of the field ridge during the rotation of the rotating disk 303, the pull plate 305 can be fixedly connected to the fifth clearance hole 304 on the rotating disk 303, which is closer to the center, by screws.

[0048] As the square cylinder 204 slides along the sliding post 203 towards its bottom, the first sliding plate 202, under force, slides along the outer wall of the sliding post 203 away from the connecting circular plate 2. At this point, the tension spring 201 is stressed and deforms along its bending direction. As the first sliding plate 202 slides along the outer wall of the sliding post 203 away from the connecting circular plate 2, the square cylinder 204 causes the first support post 209 to move along with the first sliding plate 202. 4 will move along with the first support column 209, and drive the second support column 401 and the elastic base plate 402 to move. When the elastic base plate 402 moves, the outer wall of the end away from the second support column 401 will abut against the drainage ditch between the ridges. As the second support column 401 moves, the elastic base plate 402 will be stressed and deformed along the bending direction. The end of the elastic base plate 402 away from the second support column 401 will continuously press against both sides of the plastic film on the ridge under its own elasticity. The plastic film will be straightened after being stressed.

[0049] As the square tube 204 slides along the sliding column 203 toward the top of the sliding column 203, the first sliding plate 202 is no longer under force. The tension spring 201 will recover its deformation under its own elasticity and pull the first sliding plate 202 to slide along the outer wall of the sliding column 203 toward the connecting circular plate 2. The diameter of the metal ball on the sliding column 203 is larger than the diameter of the second clearance hole on the first sliding plate 202, which can prevent the first sliding plate 202 from sliding off the outer wall of the sliding column 203 when it slides on the sliding column 203.

[0050] When the square cylinder 204 slides to a certain distance from the top of the ridge, press the end of the pressure rod 701 away from the first rotating handle 703. Under the action of the lever principle, the end of the pressure rod 701 near the first rotating handle 703 will be lifted and pull the first cable 7. Since the first cable 7 passes around the outer wall of the U-shaped cylinder 205, when the first cable 7 is pulled, the cutting box 5 will move along the inner wall of the square cylinder 204 towards the bottom of the square cylinder 204, so that the mulch film can be cut. If the ridge is low, in order to make the cutting depth of the cutting box 5 reach the standard suitable for potato planting, the length of the first cable 7 inserted into the first clearance hole 705 can be increased, the first rotating handle 703 can be tightened to fix the first cable 7, and then the end of the pressure rod 701 away from the first rotating handle 703 can be pressed to make the cutting depth of the cutting box 5 into the ridge suitable for potato planting.

[0051] As the cutting box 5 slides along the inner wall of the square cylinder 204 towards the bottom of the square cylinder 204, the outer wall of the shovel plate 210 is squeezed by the outer wall of the cutting box 5, and deforms along its bending direction. As the cutting box 5 slides, the second sliding plate 501 follows the cutting box 5 and slides along the inner wall of the first sliding groove 207 towards the bottom of the square cylinder 204. At this time, the spring 502 is stressed and deforms along its bending direction, and the cutting box 5 cuts into the ridge. At this time, the second cable 6 pulls the third baffle 507 to tilt, so that the C-shaped elastic plate 506 is stressed. With the cooperation of the weakening groove 509 on the C-shaped elastic plate 506, the C-shaped elastic plate 506 deforms along its bending direction. At this time, the third baffle 507 blocks the soil in the second chamber, and the potato planting block that falls into the first chamber through the conveying device 1 will slide along the tilt of the cutting box 5 in the first chamber. The soil is guided into the pre-cut hole of the cutting box 5. As the cutting box 5 slides towards the top of the square cylinder 204, the second sliding plate 501 slides along the inner wall of the first sliding groove 207 towards the top of the square cylinder 204. The spring 502 is no longer under force and returns to its original deformation along its bending direction, providing a certain thrust for the sliding of the second sliding plate 501. The second cable 6 is no longer taut, so the third baffle 507 is no longer under force. At this time, the C-shaped elastic plate 506 returns to its original deformation under its own elasticity, which will drive the third baffle 507 to reset, allowing the soil that was originally blocked by the third baffle 507 to fall into the pre-cut hole, realizing automatic soil covering of the potato planting block. At the same time, the baffle plate 602 scrapes off the soil adhering to the inner wall of the second chamber of the cutting box 5 when the cutting box 5 slides towards the top of the square cylinder 204, so as not to affect the operation of the next hole.
