Description

Technical Field

[0001] This invention relates to the field of agricultural technology, specifically to a potato mulching and ridge planting device and method. Background Technology

[0002] A potato mulching and ridging device is an agricultural machine used for potato cultivation. It integrates multiple functions such as ridging, sowing, fertilization, and mulching, which can significantly improve potato planting efficiency and yield. The potato mulching and ridging device is usually composed of a frame, transmission system, ridging device, sowing device, fertilization device, and mulching device. These parts work together to complete the entire process from land preparation to sowing and mulching, which can significantly improve potato planting efficiency and yield.

[0003] In the prior art, Chinese invention patent publication number CN107155423B discloses an integrated ridging and mulching machine, including a frame. From front to back, the frame is sequentially equipped with a ridging and forming mechanism, a film release and spreading mechanism, and a soil covering and pressing mechanism. A film spreading adjustment device is provided between the film release and spreading mechanism and the frame; a soil covering and pressing mechanism is provided between the soil covering and pressing mechanism and the frame. This invention can quickly and conveniently achieve locking or unlocking between the cantilever and the support base. Its structure is ingenious and reasonable, and it is easy to operate, thus improving work efficiency and mulching quality.

[0004] While the aforementioned patents have enabled the ridging and mulching of land, they still suffer from the following problems: The device first uses a ridging device to raise the land into ridges, and then a mulching device covers the ridges with mulch. During the mulching process, one end of the mulch is fixed to the end of the ridge. Then, the movement of the mulching device drives the rotating roller to rotate, thereby covering the ridge with the mulch on the rotating roller. However, because the mulch on the rotating roller is flat when it rotates onto the ridge surface, while the end face of the ridge is trapezoidal, the mulch cannot adhere well to the ridge when covering, resulting in a decrease in the sealing performance of the mulch and a reduction in its heat preservation, wind resistance, and waterproofing evaporation effects. To address this problem, we designed a potato mulching ridge planting device and method. Summary of the Invention

[0005] The purpose of this invention is to provide a potato mulching ridge planting device and method to address the problem that when mulch film is applied to ridges, the shape of the mulch film and the ridges do not match, resulting in poor adhesion between the mulch film and the ridges and a reduced sealing performance of the mulch film, thus reducing its heat preservation, wind resistance, waterproofing, and evaporation-resistant effects.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a potato mulching and ridge planting device, comprising: a mulching and ridge planting machine, wherein a first fixed plate is fixedly connected to the inner side of the mulching and ridge planting machine, a rotating roller is rotatably connected to the inner side of the first fixed plate, and mulch film is wound onto the outer wall of the rotating roller; a tension adjustment mechanism, wherein the tension adjustment mechanism is disposed at one end of the first fixed plate for adjusting the tension of the mulch film, the tension adjustment mechanism comprising two rectangular strips disposed at one end of the first fixed plate, a second rectangular block being fixedly connected to one side of each of the two rectangular strips, a fifth rotating rod being rotatably connected to the inner side of the second rectangular block, and a first rotating rod being fixedly connected to the inner side of the fifth rotating rod through the second rectangular block; a moderate bending mechanism, wherein the moderate bending mechanism is disposed on one side of the rectangular strips for adaptively bending both sides of the mulch film; and an adaptive adjustment mechanism, wherein the adaptive adjustment mechanism is disposed on one side of the first fixed plate for adjusting the bending position of the mulch film.

[0008] As a further embodiment of the present invention: the adaptive adjustment mechanism includes a disc fixedly connected to one side of the first fixed plate, a third connecting strip fixedly connected to one end of the disc, a sliding block slidably connected to the inner side of the third connecting strip, a fourth connecting strip fixedly connected to the outer wall of the sliding block, a limit rod fixedly connected to one end of the fourth connecting strip, a second drive motor installed at the other end of the disc, the output end of the second drive motor passing through to a bidirectional threaded screw fixedly connected to one end of the disc, and the sliding block being threadedly connected to the outer wall of the bidirectional threaded screw.

[0009] As a further embodiment of the present invention: the outer wall of the bidirectional threaded screw is provided with a positive thread and a negative thread, and two sliding blocks are provided, which are respectively threaded to the outer wall of the positive thread and the negative thread.

[0010] As a further embodiment of the present invention: the adaptive adjustment mechanism further includes a fifth connecting strip fixedly connected to one side of the fourth connecting strip, a first rectangular block fixedly connected to one side of the fifth connecting strip, a second fixing plate fixedly connected to one side of the first rectangular block, a second limiting strip fixedly connected to the top of the second fixing plate, a connecting plate slidably connected to the outer wall of the second limiting strip, and a straight toothed rack fixedly connected to one side of the connecting plate.

[0011] As a further embodiment of the present invention: a first limiting strip is slidably connected to the inner side of the sliding seat, and the first limiting strip is fixedly connected to the straight rack.

[0012] As a further embodiment of the present invention: the moderate bending mechanism includes a connecting seat fixedly connected to one side of the first rectangular block, a second rotating rod rotatably connected to the inner side of the connecting seat, a second fixed seat fixedly connected to one end of the second rotating rod, a third rotating rod fixedly connected to one end of the second fixed seat, and a plurality of rotating wheels rotatably connected to the outer wall of the third rotating rod.

[0013] As a further embodiment of the present invention: the moderate bending mechanism further includes a first pulley fixedly connected to the outer wall of the second rotating rod, a fourth rotating rod rotatably connected to the inner side of the connecting seat, a second pulley fixedly connected to the outer wall of the fourth rotating rod, belts installed on the outer walls of the first pulley and the second pulley, and a spur gear fixedly connected to one end of the fourth rotating rod, and the spur gear meshing with the spur rack.

[0014] This invention also discloses a method for potato mulching and ridge planting, which uses the aforementioned potato mulching and ridge planting device and includes the following steps: S1. First, a servo motor for driving the rotating roller to rotate is installed on one side of the first fixed plate. When the mulching ridge planter performs mulching operation on the field, the servo motor drives the rotating roller to rotate. The end of the mulch film is placed at one end of the ridge and covered and fixed with soil. Then, the mulch film is covered on the ridge by the rotation of the rotating roller and the movement of the mulching ridge planter, thereby covering the ridge surface. This can prevent soil moisture loss and lock in soil heat, reduce heat loss, and provide a stable growing environment for potatoes, thereby improving the overall practicality of the device. S2. The two first rotating rods are respectively attached to the top and bottom of the mulch film. When the mulch film is fixed on the ridge, if the tension of the mulch film is too low, the worker can start the first drive motor. The output end of the first drive motor drives the threaded screw to rotate, thereby driving the sliding seat to move upward, thereby driving the rectangular strip and the second connecting strip to move upward, thereby driving the two rectangular strips to move upward, so that the two first rotating rods move upward. When the first rotating rods come into contact with the mulch film, they can lift the mulch film upward, thereby tightening the mulch film, thereby increasing the tension of the mulch film, ensuring that the mulch film always maintains appropriate tension during the covering process, without wrinkles or looseness. At the same time, it also ensures that the mulch film is evenly stressed during the laying process, avoiding excessive tension that could cause damage to the mulch film or excessive looseness that could lead to waste. When the first rotating rod tightens the mulch film, it can rotate along the fifth rotating rod as the mulch film moves. This prevents the first rotating rod from causing significant resistance to the mulch film during movement, thereby improving the overall practicality of the device. At the same time, reducing the friction between the first rotating rod and the mulch film effectively prevents the mulch film from being torn by the disc, thus providing a certain degree of protection for the mulch film. This makes the entire operation process smoother, thereby improving the overall working efficiency of the device. S3. Before mulching, if the width of the ridge is greater than the distance between the two limiting rods, the operator starts the second drive motor. The output of the second drive motor drives the bidirectional threaded screw to rotate, thereby driving the two sliding blocks to move towards one of the discs, which in turn drives the fourth connecting strip to move towards the disc, thus moving the two limiting rods. This allows the two limiting rods to move to a distance that is compatible with the ridge surface, enabling the device to be adaptively adjusted according to different ridge surfaces. This allows the mulch film to fit more closely to the top of the ridge, thereby improving the overall practicality of the device. S4. Simultaneously, when the fourth connecting strip moves, it can drive the fifth connecting strip to move, thereby driving the first rectangular block to move. This allows the second drive motor to drive the first rectangular block to move while driving the limiting rod to move, thereby driving the connecting seat to move. Under the action of the connecting seat, the third rotating rod moves, allowing the third rotating rod to be adjusted synchronously with the position adjustment of the limiting rod. This allows for adaptive adjustment according to different widths of the ridge surface, enabling the third rotating rod to better bend the mulch film into an adaptive angle, thereby further improving the fit of the mulch film on the ridge, thus improving the heat preservation and waterproofing effect on potatoes, and thus improving the overall practicality of the device. S5. When the sliding seat moves downward, it can drive the first limiting strip to move downward, thereby driving the rack to move downward. Under the action of the rack, the spur gear is driven to rotate, thereby driving the fourth rotating rod to rotate, thereby driving the belt to rotate. Under the action of the belt, the second rotating rod is driven to rotate, thereby driving the second fixed seat to rotate. This allows the third rotating rod to rotate while the sliding seat moves, thus pressing the two sides of the mulch film to an appropriate angle. This allows the mulch film to form a shape that matches the ridge surface, resulting in better fit when the mulch film is covering the top of the ridge. It also reduces wrinkles, wind damage, and breakage of the mulch film, improving the utilization rate and wind resistance of the mulch film, thereby improving the overall practicality of the device. When the first rectangular block moves the connecting seat, it can also move the second fixing plate towards the center of the mulching ridge planter. This causes the rack to move synchronously through the movement of the second limiting strip, so that the rack can always drive the spur gear to rotate when it moves downward. This improves the stability of the device, as well as its working efficiency and reliability, thereby enhancing the overall practicality of the device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the cooperation of parts such as threaded screws, the first rotating rod can lift the mulch film upward when it comes into contact with it, thereby tightening the mulch film and increasing its tension. This ensures that the mulch film maintains appropriate tension during the covering process, without wrinkles or loosening. It also ensures that the mulch film is evenly stressed during the laying process, avoiding damage caused by excessive tension or waste caused by excessive looseness.

[0016] 2. Through the cooperation of components such as limiting rods, the two sliding blocks move towards one of the discs, thereby driving the fourth connecting strip to move towards the disc, which in turn moves the two limiting rods. This allows the two limiting rods to move to a distance that is compatible with the ridge surface, enabling the device to be adaptively adjusted according to different ridge surfaces. This allows the mulch film to fit more closely to the top of the ridge, thereby improving the overall practicality of the device. 3. Through the cooperation of components such as the limiting rod, the third rotating rod can be adjusted synchronously with the position adjustment of the limiting rod, thereby making adaptive adjustments according to the ridge surface of different widths. This allows the third rotating rod to better bend the mulch film into an appropriate angle, further improving the fit of the mulch film on the ridge, thus improving the heat preservation and waterproofing effect on potatoes, and thus improving the overall practicality of the device. 4. Through the cooperation of parts such as the sliding seat, the third rotating rod can rotate as the sliding seat moves, thereby pressing the two sides of the mulch film to an appropriate angle. This allows the mulch film to form a shape that matches the ridge surface, resulting in better fit when the mulch film is covering the top of the ridge. It also reduces wrinkles, wind damage, and breakage of the mulch film, improving the utilization rate and wind resistance of the mulch film, thus enhancing the overall practicality of the device. 5. Through the cooperation of the first rectangular block and other parts, the rack can always drive the spur gear to rotate when it moves downward, thereby improving the stability of the device, as well as its working efficiency and reliability, thus improving the overall practicality of the device.

The following describes embodiments of the invention based on its overall structure.

[0021] Example 1: Please refer to Figures 1-12 This embodiment provides a potato mulching and ridge planting device, including: a mulching and ridge planting machine 1, a first fixed plate 2 fixedly connected to the inner side of the mulching and ridge planting machine 1, a rotating roller 5 rotatably connected to the inner side of the first fixed plate 2, and a mulch film 3 rolled up on the outer wall of the rotating roller 5; a tension adjustment mechanism, the tension adjustment mechanism is set at one end of the first fixed plate 2, used to adjust the tension of the mulch film 3, the tension adjustment mechanism includes two rectangular strips 13 set at one end of the first fixed plate 2, a second rectangular block 38 fixedly connected to one side of each of the two rectangular strips 13, a fifth rotating rod 39 rotatably connected to the inner side of the second rectangular block 38, and a first rotating rod 14 fixedly connected to the inner side of the fifth rotating rod 39 through the second rectangular block 38; First, a servo motor is installed on one side of the first fixed plate 2 to drive the rotating roller 5 to rotate. When the mulching ridge planter 1 performs mulching operation on the field, the servo motor drives the rotating roller 5 to rotate. The end of the mulch film 3 is placed at one end of the ridge and covered and fixed with soil. Then, the rotating roller 5 rotates and the mulching ridge planter 1 moves to cover the mulch film 3 on the ridge, thereby covering the ridge surface. This can prevent soil moisture loss and lock in soil heat, reducing heat loss and providing a stable growing environment for potatoes, thus improving the overall practicality of the device.

[0022] Example 2: The tension adjustment mechanism further includes a first connecting strip 6 fixedly connected to one side of the first fixed plate 2. One end of the first connecting strip 6 is fixedly connected to a fixed frame 23. A sliding seat 7 is slidably connected to the outer wall of the fixed frame 23, and the sliding seat 7 is fixedly connected to a rectangular strip 13. A second connecting strip 8 is fixedly connected to the bottom of the sliding seat 7. A fixed strip 37 is fixedly connected to the inner side of the second connecting strip 8, and the fixed strip 37 is fixedly connected to another rectangular strip 13. A first drive motor 9 is installed on the top of the fixed frame 23. The output end of the first drive motor 9 extends through to the inner side of the fixed frame 23 and is fixedly connected to a threaded screw 10. The sliding seat 7 is threadedly connected to the outer wall of the threaded screw 10. Two first rotating rods 14 are respectively attached to the top and bottom of the mulch film 3. When the mulch film 3 is fixed on the ridge, if the tension of the mulch film 3 is too small, the worker can start the first drive motor 9. The output end of the first drive motor 9 drives the threaded screw 10 to rotate, thereby driving the sliding seat 7 to move upward, thereby driving the rectangular strip 13 and the second connecting strip 8 to move upward, thereby driving the two rectangular strips 13 to move upward, so that the two first rotating rods 14 move upward. When the first rotating rods 14 come into contact with the mulch film 3, they can lift the mulch film 3 upward, thereby tightening the mulch film 3, thereby increasing the tension of the mulch film 3, ensuring that the mulch film always maintains appropriate tension during the covering process, without wrinkles or looseness, and also ensuring that the mulch film 3 is evenly stressed during the laying process, avoiding excessive tension that would cause damage to the mulch film or excessive looseness that would lead to waste. When the first rotating rod 14 tightens the mulch film 3, it can rotate along the fifth rotating rod 39 as the mulch film 3 moves. This prevents the first rotating rod 14 from causing significant resistance to the mulch film 3 during movement, thus improving the overall practicality of the device. At the same time, reducing the friction between the first rotating rod 14 and the mulch film 3 effectively prevents the mulch film 3 from being scratched by the disc 4, thus providing a certain degree of protection for the mulch film 3. This makes the entire operation process smoother and improves the working efficiency of the entire device.

[0023] Example 3: Adaptive adjustment mechanism. The adaptive adjustment mechanism is set on one side of the first fixed plate 2 and is used to adjust the bending position of the mulch film 3. The adaptive adjustment mechanism includes a disc 4 fixedly connected to one side of the first fixed plate 2. A third connecting strip 15 is fixedly connected to one end of the disc 4. A sliding block 16 is slidably connected to the inner side of the third connecting strip 15. A fourth connecting strip 17 is fixedly connected to the outer wall of the sliding block 16. A limit rod 20 is fixedly connected to one end of the fourth connecting strip 17. A second drive motor 18 is installed at the other end of the disc 4. The output end of the second drive motor 18 passes through to one end of the disc 4 and is fixedly connected to a bidirectional threaded screw 19. The sliding block 16 is threadedly connected to the outer wall of the bidirectional threaded screw 19. The outer wall of the bidirectional threaded screw 19 is provided with positive thread and negative thread. There are two sliding blocks 16. The two sliding blocks 16 are respectively threadedly connected to the outer wall of the positive thread and the negative thread. Before mulching, when the width of the ridge is greater than the distance between the two limiting rods 20, the operator starts the second drive motor 18. The output of the second drive motor 18 drives the bidirectional threaded screw 19 to rotate, thereby driving the two sliding blocks 16 to move towards a disc 4, which in turn drives the fourth connecting strip 17 to move towards the disc 4, thus moving the two limiting rods 20. This allows the two limiting rods 20 to move to a distance that is compatible with the ridge surface, enabling the device to be adaptively adjusted according to different ridge surfaces. This allows the mulch film 3 to fit more closely to the top of the ridge, thereby improving the overall practicality of the device.

[0024] Example 4: The adaptive adjustment mechanism further includes a fifth connecting strip 21 fixedly connected to one side of the fourth connecting strip 17. A first rectangular block 22 is fixedly connected to one side of the fifth connecting strip 21. A second fixing plate 33 is fixedly connected to one side of the first rectangular block 22. A second limiting strip 35 is fixedly connected to the top of the second fixing plate 33. A connecting plate 36 is slidably connected to the outer wall of the second limiting strip 35. A rack 12 is fixedly connected to one side of the connecting plate 36. A first limiting strip 11 is slidably connected to the inner side of the sliding seat 7, and the first limiting strip 11 is fixedly connected to the rack 12. The moderate bending mechanism includes a connecting seat 24 fixedly connected to one side of the first rectangular block 22. A second rotating rod 25 is rotatably connected to the inner side of the connecting seat 24. A second fixing seat 26 is fixedly connected to one end of the second rotating rod 25. A third rotating rod 27 is fixedly connected to one end of the second fixing seat 26. A plurality of rotating wheels 28 are rotatably connected to the outer wall of the third rotating rod 27. Simultaneously, when the fourth connecting bar 17 moves, it can drive the fifth connecting bar 21 to move, thereby driving the first rectangular block 22 to move. This allows the second drive motor 18 to drive the first rectangular block 22 to move while driving the limit rod 20 to move, thereby driving the connecting seat 24 to move. Under the action of the connecting seat 24, the third rotating rod 27 moves, so that the third rotating rod 27 can be adjusted synchronously with the position adjustment of the limit rod 20. This allows for adaptive adjustment according to different widths of the ridge surface, enabling the third rotating rod 27 to better bend the mulch film 3 into an adaptive angle, thereby further improving the fit of the mulch film 3 on the ridge, thus improving the heat preservation and waterproofing effect on potatoes, and thus improving the overall practicality of the device.

[0025] Example 5: The moderate bending mechanism also includes a first pulley 29 fixedly connected to the outer wall of the second rotating rod 25, a fourth rotating rod 31 rotatably connected to the inner side of the connecting seat 24, a second pulley 32 fixedly connected to the outer wall of the fourth rotating rod 31, a belt 30 installed on the outer walls of the first pulley 29 and the second pulley 32, and a spur gear 34 fixedly connected to one end of the fourth rotating rod 31, and the spur gear 34 meshes with the spur rack 12; When the sliding seat 7 moves downward, it can drive the first limiting strip 11 to move downward, thereby driving the rack 12 to move downward. Under the action of the rack 12, the spur gear 34 is driven to rotate, thereby driving the fourth rotating rod 31 to rotate, thereby driving the belt 30 to rotate. Under the action of the belt 30, the second rotating rod 25 is driven to rotate, thereby driving the second fixed seat 26 to rotate. This allows the third rotating rod 27 to rotate as the sliding seat 7 moves, thereby pressing the two sides of the mulch film 3 to an appropriate angle, so that the mulch film 3 can form a shape that matches the ridge surface. This allows the mulch film 3 to form a better fit when covering the top of the ridge, while also reducing wrinkles, wind damage and breakage of the mulch film 3, improving the utilization rate and wind resistance of the mulch film 3, thereby improving the overall practicality of the device. When the first rectangular block 22 moves the connecting seat 24, it can move the second fixed plate 33 towards the center of the mulching ridge planter 1. This causes the second limiting strip 35 to move synchronously, driving the rack 12 to move synchronously. As the rack 12 moves downward, it can always drive the spur gear 34 to rotate, thereby improving the stability of the device, as well as its working efficiency and reliability, thus improving the overall applicability of the device.

[0026] The following describes a method for potato mulching and ridge planting, based on the aforementioned potato mulching and ridge planting device, specifically including the following steps: S1. First, a servo motor for driving the rotating roller 5 to rotate is installed on one side of the first fixed plate 2. When the mulching ridge planter 1 performs mulching operation on the field, the rotating roller 5 is driven to rotate by the servo motor. The end of the mulch film 3 is placed at one end of the ridge and covered and fixed with soil. Then, the mulch film 3 is covered on the ridge by rotating the rotating roller 5 and moving the mulching ridge planter 1, thereby covering the ridge surface. This can prevent soil moisture loss and lock in soil heat, reduce heat loss, and provide a stable growth environment for potatoes, thereby improving the overall practicality of the device. S2. The two first rotating rods 14 are respectively attached to the top and bottom of the mulch film 3. When the mulch film 3 is fixed on the ridge, if the tension of the mulch film 3 is too small, the workers can start the first drive motor 9. The output end of the first drive motor 9 drives the threaded screw 10 to rotate, thereby driving the sliding seat 7 to move upward, thereby driving the rectangular strip 13 and the second connecting strip 8 to move upward, thereby driving the two rectangular strips 13 to move upward, so that the two first rotating rods 14 move upward. When the first rotating rods 14 come into contact with the mulch film 3, they can lift the mulch film 3 upward, thereby tightening the mulch film 3, thereby increasing the tension of the mulch film 3, ensuring that the mulch film always maintains appropriate tension during the covering process, without wrinkles or looseness, and also ensuring that the mulch film 3 is evenly stressed during the laying process, avoiding excessive tension that would cause damage to the mulch film or excessive looseness that would lead to waste. When the first rotating rod 14 tightens the mulch film 3, the first rotating rod 14 can rotate along the fifth rotating rod 39 when the mulch film 3 moves. This prevents the first rotating rod 14 from causing significant resistance to the mulch film 3 when it moves, thereby improving the overall practicality of the device. At the same time, reducing the friction between the first rotating rod 14 and the mulch film 3 can effectively prevent the mulch film 3 from being scratched by the disc 4, thus providing a certain degree of protection for the mulch film 3. This makes the entire operation process smoother, thereby improving the working efficiency of the entire device. S3. Before mulching, when the width of the ridge is greater than the distance between the two limiting rods 20, the operator starts the second drive motor 18. The output end of the second drive motor 18 drives the bidirectional threaded screw 19 to rotate, thereby driving the two sliding blocks 16 to move towards a disc 4, which in turn drives the fourth connecting strip 17 to move towards the disc 4, thus moving the two limiting rods 20. This allows the two limiting rods 20 to move to a distance that is compatible with the ridge surface, so that the device can be adaptively adjusted according to different ridge surfaces, so that the mulch film 3 can fit more closely to the top of the ridge, thereby improving the overall practicality of the device. S4. Simultaneously, when the fourth connecting bar 17 moves, it can drive the fifth connecting bar 21 to move, thereby driving the first rectangular block 22 to move. This allows the second drive motor 18 to drive the first rectangular block 22 to move while driving the limit rod 20 to move, thereby driving the connecting seat 24 to move. Under the action of the connecting seat 24, the third rotating rod 27 moves, so that the third rotating rod 27 can be adjusted synchronously with the position adjustment of the limit rod 20. This allows for adaptive adjustment according to different widths of the ridge surface, so that the third rotating rod 27 can better bend the mulch film 3 into an adaptive angle, thereby further improving the fit of the mulch film 3 on the ridge, thus improving the heat preservation and waterproofing effect on potatoes, and thus improving the overall practicality of the device. S5. When the sliding seat 7 moves downward, it can drive the first limiting strip 11 to move downward, thereby driving the rack 12 to move downward. Under the action of the rack 12, the spur gear 34 is driven to rotate, thereby driving the fourth rotating rod 31 to rotate, thereby driving the belt 30 to rotate. Under the action of the belt 30, the second rotating rod 25 is driven to rotate, thereby driving the second fixed seat 26 to rotate. This allows the third rotating rod 27 to rotate as the sliding seat 7 moves, thereby pressing the two sides of the mulch film 3 to an appropriate angle, so that the mulch film 3 can form a shape that matches the ridge surface. This allows the mulch film 3 to form a better fit when covering the top of the ridge, and also reduces the wrinkles, wind damage and breakage of the mulch film 3, improving the utilization rate and wind resistance of the mulch film 3, thereby improving the overall practicality of the device. When the first rectangular block 22 moves the connecting seat 24, it can move the second fixed plate 33 towards the center of the mulching ridge planter 1. This causes the second limiting strip 35 to move synchronously, driving the rack 12 to move synchronously. As the rack 12 moves downward, it can always drive the spur gear 34 to rotate, thereby improving the stability of the device, as well as its working efficiency and reliability, thus improving the overall practicality of the device.

9. A method for mulching and planting potatoes on raised beds, characterized in that, The potato mulching and ridge planting device according to claim 8 includes the following steps: S1. First, a servo motor for driving the rotating roller (5) to rotate is installed on one side of the first fixed plate (2). When the mulching ridge planter (1) performs mulching operation on the field, the rotating roller (5) is driven to rotate by the servo motor. The end of the mulch film (3) is placed at one end of the ridge and covered and fixed with soil. The mulch film (3) is covered on the ridge by the rotation of the rotating roller (5) and the movement of the mulching ridge planter (1), thereby achieving the covering of the ridge surface. This can prevent the loss of soil moisture and lock in soil heat, reduce heat loss, and provide a stable growth environment for potatoes, thereby improving the overall practicality of the device. S2. The two first rotating rods (14) are respectively attached to the top and bottom of the mulch film (3). When the mulch film (3) is fixed on the ridge, if the tension of the mulch film (3) is too small, the workers can start the first drive motor (9). The output end of the first drive motor (9) drives the threaded screw (10) to rotate, thereby driving the sliding seat (7) to move upward, thereby driving the rectangular strip (13) and the second connecting strip (8) to move upward, thereby driving the two rectangular strips (13) to move upward, thereby causing the two first rotating rods (14) to move upward, so that when the first rotating rod (14) contacts the mulch film (3), it can lift the mulch film (3) upward, thereby tightening the mulch film (3), thereby improving the tension of the mulch film (3), ensuring that the mulch film always maintains a moderate tension during the covering process, without wrinkles or looseness, and also ensuring that the mulch film (3) is evenly stressed during the laying process, avoiding excessive tension leading to mulch film damage or excessive looseness leading to waste; When the first rotating rod (14) tightens the mulch film (3), the first rotating rod (14) can rotate along the fifth rotating rod (39) when the mulch film (3) moves. This prevents the first rotating rod (14) from causing significant resistance to the mulch film (3) when it moves, thereby improving the overall practicality of the device. At the same time, reducing the friction between the first rotating rod (14) and the mulch film (3) can effectively prevent the mulch film (3) from being scratched by the disc (4), thus providing a certain degree of protection for the mulch film (3). This makes the entire operation process smoother and improves the working efficiency of the entire device. S3. Before the mulching is performed, when the width of the ridge is greater than the distance between the two limiting rods (20), the worker starts the second drive motor (18). The output end of the second drive motor (18) drives the bidirectional threaded screw (19) to rotate, thereby driving the two sliding blocks (16) to move towards a disk (4) respectively, thereby driving the fourth connecting strip (17) to move towards the disk (4), thereby causing the two limiting rods (20) to move, so that the two limiting rods (20) can move to a distance that is adapted to the ridge surface, so that the device can be adaptively adjusted according to different ridge surfaces, so that the mulch film (3) can fit more closely to the top of the ridge, thereby improving the overall practicality of the device. S4. Simultaneously, when the fourth connecting strip (17) moves, it can drive the fifth connecting strip (21) to move, thereby driving the first rectangular block (22) to move. This allows the second drive motor (18) to drive the first rectangular block (22) to move while driving the limiting rod (20) to move, thereby driving the connecting seat (24) to move. Under the action of the connecting seat (24), the third rotating rod (27) moves, so that the third rotating rod (27) can be synchronously adjusted during the position adjustment process of the limiting rod (20), thereby making adaptive adjustments according to different widths of the ridge surface. This allows the third rotating rod (27) to better bend the mulch film (3) into an adaptive angle, thereby further improving the fit of the mulch film (3) on the ridge, thereby improving the heat preservation and waterproofing effect on potatoes, and thus improving the overall practicality of the device. S5. When the sliding seat (7) moves downward, it can drive the first limiting strip (11) to move downward, thereby driving the rack (12) to move downward. Under the action of the rack (12), the spur gear (34) is driven to rotate, thereby driving the fourth rotating rod (31) to rotate, thereby driving the belt (30) to rotate, thereby driving the second rotating rod (25) to rotate, thereby driving the second fixed seat (26) to rotate. Thus, the third rotating rod (27) can rotate while the sliding seat (7) moves, thereby pressing the two sides of the mulch film (3) into an appropriate angle, so that the mulch film (3) can form a shape that matches the ridge surface, so that the mulch film (3) can form a better fit when covering the top of the ridge, and also reduce the wrinkles, wind damage and breakage of the mulch film (3), improve the utilization rate and wind resistance of the mulch film (3), thereby improving the overall practicality of the device. When the first rectangular block (22) moves the connecting seat (24), it can move the second fixing plate (33) towards the center of the mulching ridge planter (1). Thus, the second limiting strip (35) moves and drives the rack (12) to move synchronously. This allows the rack (12) to always drive the spur gear (34) to rotate when it moves downward, thereby improving the stability of the device, as well as its working efficiency and reliability, thus improving the overall practicality of the device.
