Benefits of technology

[0019] 1. This invention incorporates a film-exit assembly, allowing the device to rub against the ground via a film-covering frame. When the device encounters hard soil, decelerates momentarily, or pauses briefly, a Hall sensor detects a decrease in the film-covering frame's rotation speed. This triggers an electric telescopic rod that moves the extrusion plate downwards, allowing hydraulic oil from the storage tank to enter the piston cylinder. This increases the friction between the friction frame and the roller shaft, further reducing the roller shaft's rotation speed. This results in a sudden increase in unwinding damping, making it difficult for the roller shaft to rotate and preventing excessive film pull-out. This also prevents the film from loosening or piling up due to machine pauses. Similarly, when the device passes over hard soil or accelerates again, the Hall sensor detects an increase in the film-covering frame's rotation speed. This triggers an electric telescopic rod that moves the extrusion plate upwards, reducing friction on the roller shaft. This allows the roller shaft to rotate more smoothly, enabling the film to be pulled out quickly and preventing tearing due to excessive tension.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an integrated machine for planting and mulching corn in dryland areas. Background Technology

[0002] In the process of dryland corn planting, mulching is a core process for conserving moisture, resisting drought, suppressing weeds, and increasing soil temperature. The integrated sowing and mulching machine has been widely used in large-scale dryland planting scenarios.

[0003] In actual field operations, existing dryland corn planting and mulching integrated machines are prone to high-frequency micro-movements, bumps, and speed fluctuations due to uneven soil flatness and significant differences in soil hardness. Furthermore, these machines often employ rigid transmission structures that cannot dynamically adapt to changes in soil resistance and the micro-movements of the machine. When the machine accelerates or local soil resistance increases suddenly, the unwinding speed of the mulch film lags behind the machine's speed, easily causing the mulch film to be stretched too tightly, resulting in localized tears and thin-edge breakage. Conversely, when the machine decelerates, experiences bumps and falls, or soil resistance decreases suddenly, the unwinding speed of the mulch film is too fast, and excess film cannot be laid out neatly in time, leading to looseness, wrinkles, and accumulation. This makes the mulch film susceptible to edge curling and soil leakage under field wind conditions, and in severe cases, entire sheets of film may be lifted or run away.

[0004] Combining the above issues, we find that existing dryland corn planting and mulching integrated machines are difficult to avoid all the problems mentioned above when in use. Even if they can be solved, they require the use of external tools, thus failing to achieve the desired results. Therefore, we propose a dryland corn planting and mulching integrated machine.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention incorporates a film-exit assembly, allowing the device to rub against the ground via a film-covering frame. When the device encounters hard soil, decelerates momentarily, or pauses briefly, a Hall sensor detects a decrease in the film-covering frame's rotation speed. This triggers an electric telescopic rod that moves the extrusion plate downwards, allowing hydraulic oil from the storage tank to enter the piston cylinder. This increases the friction between the friction frame and the roller shaft, further reducing the roller shaft's rotation speed. This results in a sudden increase in unwinding damping, making it difficult for the roller shaft to rotate and preventing excessive film pull-out. This also prevents the film from loosening or piling up due to machine pauses. Similarly, when the device passes over hard soil or accelerates again, the Hall sensor detects an increase in the film-covering frame's rotation speed. This triggers an electric telescopic rod that moves the extrusion plate upwards, reducing friction on the roller shaft. This allows the roller shaft to rotate more smoothly, enabling the film to be pulled out quickly and preventing tearing due to excessive tension.

[0020] 2. This invention incorporates a soil-covering assembly. The device's soil-covering wheel deflects as the extrusion plate moves up and down. When the device encounters hard soil clods, decelerates momentarily, or pauses briefly, the film extrusion speed decreases. This causes the extrusion plate, in conjunction with the connecting rod, to move the toothed plate, further reducing the deflection angle of the soil-covering wheel and the amount of soil covered. This reduces edge resistance and prevents tearing. Simultaneously, an electric cylinder, in conjunction with a sealing plate, reduces the amount of soil extruded from the pressing cylinder, further decreasing the amount of soil on the film and preventing damage from excessive soil. Similarly, when the device passes over hard soil clods or accelerates again, the extrusion plate, in conjunction with the connecting rod, moves the toothed plate upwards, increasing the deflection angle of the soil-covering wheel and increasing the amount of soil covered. This increases edge friction, maintaining tension. Simultaneously, an electric cylinder, in conjunction with a sealing plate, increases the amount of soil extruded from the pressing cylinder, preventing the film from being blown away by strong winds.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-5 This invention provides a technical solution: an integrated dryland corn planting and mulching machine, comprising a frame 1, with a processing mechanism 2 inside the frame 1, the processing mechanism 2 including a plow 201 fixedly installed inside the frame 1, a ridging device 202 and a mulching frame 203 fixedly installed on the inner wall of the frame 1, a seeder 204 fixedly installed on the outer surface of the frame 1, and a controller 205 fixedly installed on the outer surface of the frame 1. The operator presets the machine's operating parameters in advance through the controller 205, including corn planting spacing, mulching width, basic mulching speed and mulching base thickness. After the machine completes a power-on self-check, it is towed by a tractor into the dryland plot to be operated. The entire machine operation process is completed sequentially and in conjunction with plowing and land preparation, ridging and forming, mulching film laying, mulching edge soil compaction, and precision corn planting.

[0036] The machine frame 1 is equipped with a film dispensing assembly 3.

[0037] As a further definition of the film-ejection assembly 3 of the present invention, the film-ejection assembly 3 includes a mounting frame 301. The bottom surface of the mounting frame 301 is fixedly connected to the upper surface of the frame 1. Two electric push rods 302 are fixedly mounted on the inner wall of the mounting frame 301. The telescopic ends of the two electric push rods 302 are jointly fixedly mounted with a connecting plate 303. The outer surface of the connecting plate 303 and the interior of the mounting frame 301 are rotatably connected with fixed plates 304. The interiors of the two fixed plates 304 are jointly rotatably connected with a roller shaft 305. The distance between the two fixed plates 304 is adjusted by the power provided by the electric push rods 302, thereby facilitating the disassembly and installation of the roller shaft 305. A rotary motor 306 is fixedly mounted on the outer surface of the mounting frame 301. The output end of the rotary motor 306 is connected to one of the fixed plates 304. The outer surface of the fixed plate 304 is fixedly connected. A storage box 307 is fixedly installed on the upper surface of the mounting frame 301. A connecting frame 308 is fixedly installed on the upper surface of the storage box 307. An electric telescopic rod 309 is fixedly installed on the telescopic end of the connecting frame 308. An extrusion plate 310 is fixedly installed on the telescopic end of the electric telescopic rod 309. Two conveying pipes 311 are fixedly connected to the outer surface of the storage box 307. A rotary motor 312 is fixedly installed on the upper surface of the mounting frame 301. The output end of the rotary motor 312 passes through the mounting frame 301 and is fixedly installed with a connecting gear 313. Two moving plates 314 are slidably connected inside the mounting frame 301. A rack plate 315 is fixedly installed on the inner wall of each moving plate 314. The outer surface of each rack plate 315 is connected to the connecting plate 313. The outer surfaces of gears 313 mesh with each other. A piston cylinder 316 is fixedly mounted on the outer surface of each moving plate 314. One end of each conveying pipe 311 extends into the interior of the piston cylinder 316. A friction frame 317 is slidably connected inside each set of piston cylinders 316. The inner wall of each friction frame 317 contacts the outer surface of the roller 305. A Hall sensor 318 is fixedly mounted on the inner wall of the film covering frame 203. When the roller 305 carrying the mulch rotates, the friction frame 317 constantly provides a certain amount of friction, facilitating subsequent increases or decreases in friction. By providing the film outlet assembly 3, the device contacts and rubs against the ground through the film covering frame 203. When the device encounters hard soil, experiences instantaneous deceleration, or a brief pause, the Hall sensor 318 detects this. As the rotational speed of the film-covering frame 203 decreases, the electric telescopic rod 309 drives the extrusion plate 310 downwards, allowing hydraulic oil inside the storage tank 307 to enter the piston cylinder 316. This increases the friction between the friction frame 317 and the roller shaft 305, thereby reducing the rotational speed of the roller shaft 305. This results in a sudden increase in unwinding damping, making it difficult for the roller shaft 305 to rotate, thus preventing the film from being pulled out excessively and preventing the film from loosening or piling up due to machine stagnation. Similarly, when the device passes over hard soil or accelerates forward again, the Hall sensor 318 detects an increase in the rotational speed of the film-covering frame 203, causing the electric telescopic rod 309 to drive the extrusion plate 310 upwards, thereby reducing friction on the roller shaft 305. Therefore, the roller shaft 305 can rotate more smoothly.Allow the mulch film to be pulled out quickly, avoiding tearing due to excessive tension.

[0038] A mounting plate 5 is fixedly installed on the outer surface of the frame 1. Several fixing bolts 6 are provided inside the mounting plate 5. The installation of the mounting plate 5 and the fixing bolts 6 facilitates the connection of the device with mobile equipment such as tractors, thereby facilitating the movement of the device.

[0039] Two sliders 7 are fixedly installed on the upper surface of each movable plate 314. The inner wall of the mounting bracket 301 is provided with two sets of sliding grooves 8. Each slider 7 is slidably connected inside the sliding groove 8. The installation of the sliders 7 and the sliding grooves 8 plays a role in limiting the movement trajectory of the movable plate 314, thereby preventing the movable plate 314 from deviating from the movement trajectory when moving, and thus ensuring the stability of the movement of the movable plate 314.

[0040] Each rack plate 315 has a slide plate 9 fixedly installed on its upper surface. The inner wall of the mounting bracket 301 has two slide rails 10. Each slide plate 9 is slidably connected inside the slide rail 10. The installation of the slide plate 9 and the slide rail 10 restricts the movement trajectory of the rack plate 315, thereby ensuring the stability of the movement of the rack plate 315.

[0041] The specific implementation of this embodiment is as follows: During use, the tractor pulls the entire machine forward at a constant speed, the film-covering frame 203 rotates at a constant speed, the Hall sensor 318 provides feedback on a stable speed signal, the controller 205 determines that the implement is in a stable operating state, the electric telescopic rod 309 on the mounting frame 301 remains in the neutral position, the hydraulic oil in the storage box 307 is pressed into the piston cylinders 316 on both sides through the delivery pipe 311, the rotary motor 312 drives the connecting gear 313 to rotate at a constant speed, thereby driving the rack plate 315 meshing with it to move, thus causing the rack plate 315 to move. Plate 314 slides to one side closer to each other, causing piston cylinder 316 to move synchronously, thereby causing friction frame 317 to contact the outer wall of roller shaft 305, thus applying a certain frictional resistance. At the same time, rotating motor 306, in conjunction with fixed plate 304, drives roller shaft 305 to release mulch film at a preset speed. Mulch film is pulled flat by mulching frame 203 and laid on top of the ridge formed by ridging device 202. Plowing device 201 on the inner side of frame 1 pre-breaks hardened soil clods, providing a flat base for ridging and mulching. Seeder 204 follows the mulching process, accurately punching holes in the middle of mulch film to drop seeds, completing corn sowing.

[0042] When the machine experiences bumps, jamming, or a sudden decrease in speed while compacting hard soil clods, the rotational speed of the film covering frame 203 drops sharply due to ground resistance. The Hall sensor 318 collects the low-speed signal and feeds it back to the controller 205. The controller 205 then sends a command to extend the electric telescopic rod 309 at the lower end of the connecting frame 308 downwards, pushing the extrusion plate 310 down to press down the hydraulic oil inside the storage tank 307. The hydraulic oil then flows under high pressure into the left and right piston cylinders 316 through the two delivery pipes 311. At this time, the resistance on the roller 305 increases, thus slowing down the rotational speed and immediately reducing the amount of film pulled out. This prevents the film from being unrestrainedly unwound, accumulating, wrinkled, or collapsing due to machine stagnation or traction failure, thus addressing the problem from the source. To avoid the potential problems of film curling at the edges and being blown off by strong winds later on, the equipment resumes normal travel speed after overcoming protruding hard soil clods. The rotation speed of the film covering frame 203 returns to the rated value, and the Hall sensor 318 sends an acceleration signal to the controller 205. The controller 205 controls the electric telescopic rod 309 to retract, pulling the extrusion plate 310 upward. The internal pressure of the storage tank 307 decreases, and the hydraulic oil inside the piston cylinder 316 flows back to the storage tank 307, reducing frictional resistance. As a result, the roller 305 rotates rapidly under the drive of the rotating motor 306, accelerating the release speed of the film and matching the machine's travel speed. This prevents the film from being stretched too tight, overloaded, and tearing or breaking at the edges.

[0043] Example 2: Please refer to Figure 1 , Figure 6 , Figure 7 The present invention provides a technical solution: an integrated machine for planting and mulching corn in dryland. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The machine frame 1 is equipped with a soil covering component 4.

[0044] As a further definition of the soil covering component 4 of the present invention, the soil covering component 4 includes a connecting rod 401, the bottom end of which is fixedly connected to the upper surface of the extrusion plate 310, and a toothed plate 403 is fixedly installed on the other end of the connecting rod 401. Two rotating shafts 405 are rotatably connected inside the frame 1, and a soil covering wheel 406 is rotatably connected to the bottom end of each rotating shaft 405. A fixed gear 407 is fixedly installed at the top end of one of the rotating shafts 405. A rotating shaft 408 is fixedly installed on the upper surface of the frame 1, and a connecting wheel 406 is fixedly installed on the outer surface of the other rotating shaft 405 and the outer surface of the rotating shaft 408. 9. A belt 410 is fitted onto the outer surfaces of two connecting wheels 409. A transmission gear 411 is fixedly installed at the top of the rotating shaft 408. A first conical wheel 412 is fixedly installed at the top of another rotating shaft 405. A bearing bracket 413 is fixedly installed on the upper surface of the frame 1. A rotating column 414 is rotatably connected inside the bearing bracket 413. A second conical wheel 415 is fixedly installed at one end of the rotating column 414. The outer surface of the second conical wheel 415 meshes with the outer surface of the first conical wheel 412. A mounting gear 416 is fixedly installed at the other end of the rotating column 414. The outer surface of the mounting gear 416 meshes with the toothed plate. The outer surfaces of 403 mesh with each other, and the inner part of the frame 1 is rotatably connected to a pressing cylinder 417. An electric cylinder 402 is fixedly installed on the inner wall of the pressing cylinder 417. A sealing plate 404 is fixedly installed on the telescopic end of the electric cylinder 402. By setting up the soil covering component 4, the device moves up and down according to the pressing plate 310, thereby driving the soil covering wheel 406 to deflect. When the device encounters hard soil clods, decelerates momentarily, or pauses briefly, the film extrusion speed decreases, thereby causing the pressing plate 310 to move in conjunction with the connecting rod 401 to drive the toothed plate 403 to move, which in turn reduces the deflection angle of the soil covering wheel 406, thus reducing the soil covering speed. The amount of soil removed is reduced, which lowers the resistance at the edge of the membrane and prevents tearing. At the same time, the amount of soil removed by the pressing cylinder 417 is reduced by the electric cylinder 402 in conjunction with the sealing plate 404, thereby reducing the amount of soil covering the membrane and avoiding damage to the membrane due to excessive soil. Similarly, when the device passes over hard soil clods or accelerates forward again, the pressing plate 310 in conjunction with the connecting rod 401 drives the toothed plate 403 to move upward, thereby increasing the deflection angle of the covering wheel 406, increasing the amount of soil covering, and thus increasing the friction at the edge of the membrane to maintain tension. At the same time, the amount of soil removed by the pressing cylinder 417 is increased by the electric cylinder 402 in conjunction with the sealing plate 404, thereby preventing the mulch film from being blown away by strong winds.

[0045] A T-shaped plate 11 is fixedly installed on the outer surface of the toothed plate 403. A groove 12 is provided on the outer surface of the frame 1. The T-shaped plate 11 is slidably connected inside the groove 12. The installation of the T-shaped plate 11 and the groove 12 restricts the movement trajectory of the toothed plate 403.

[0046] A rubber sleeve 13 is fixedly installed on the inner wall of the pressing cylinder 417. The outer surface of the rubber sleeve 13 is fixedly connected to the outer surface of the sealing plate 404. The rubber sleeve 13 is made of rubber material and has good extensibility. The rubber sleeve 13 is used to separate the mud inside the pressing cylinder 417 from the electric cylinder 402, so as to avoid the mud from damaging the electric cylinder 402.

[0047] A storage battery 14 is fixedly installed on the outer surface of the frame 1. The storage battery 14 is electrically connected to the plow 201, the seeder 204, the controller 205, the electric push rod 302, the rotary motor 306, the electric telescopic rod 309, the rotary motor 312, the Hall sensor 318, and the electric cylinder 402 through wires and contact pads. The installation of the storage battery 14 can provide power to the electrical equipment of the device.

[0048] A protective box 15 is fixedly installed on the outer surface of the frame 1. A protective cover 16 is rotatably hinged to the outer surface of the protective box 15. The installation of the protective box 15 and the protective cover 16 serves to protect the electronic equipment inside the protective box 15.

[0049] The specific implementation of this embodiment is as follows: The upper end of the connecting rod 401 is fixed on the extrusion plate 310, and the lower end is connected to the toothed plate 403. The toothed plate 403 slides vertically within the groove 12 of the frame 1 by relying on the T-shaped plate 11 to ensure that the lifting action does not deviate. During the process of the machine jamming and decelerating, and the extrusion plate 310 moving downward, the connecting rod 401 pulls the toothed plate 403 downward, so that the toothed plate 403 meshes with the mounting gear 416 downward, so that the mounting gear 416 drives the rotating column 414 to rotate inside the bearing bracket 413, thereby causing the second conical wheel 415 at the end of the rotating column 414 to mesh with the first... The conical wheel 412 drives the rotating shaft 405 connected to the first conical wheel 412 to rotate slightly. This rotating shaft 405, through the connecting wheel 409 and the belt 410, drives the rotating shaft 408 and the transmission gear 411 to operate in conjunction. This causes the transmission gear 411 to mesh with the fixed gear 407, achieving a synchronous slight deflection of the other set of rotating shafts 405. The soil-covering wheels 406 at the bottom of the two rotating shafts 405 expand outward, the inclination angle decreases, the amount of soil inserted and removed decreases, and the thickness of the soil covering on both sides of the mulch film becomes thinner. This reduces the squeezing and pulling of the soil on the low-speed, taut mulch film, preventing the heavy pressure of the soil covering from tearing the edges of the mulch film. In this situation, the electric cylinder 402 built into the pressing cylinder 417 extends, pushing the sealing plate 404 to seal the soil outlet of the pressing cylinder 417 under the sealing protection of the rubber sleeve 13, greatly reducing the amount of soil falling into the middle of the mulch film on the ridge surface, and avoiding excessive soil pressure that could damage the film. The soil inside the pressing cylinder 417 is pushed into the pressing cylinder 417 by the soil covering wheel 406, thereby pressing the soil on the top of the mulch film. Similarly, when the equipment returns to normal and suddenly accelerates, the extrusion plate 310 rises upward, and the connecting rod 401 drives the toothed plate 403 to slide upward, driving the mounting gear 416 and the rotating gear in the opposite direction. The moving column 414 and others rotate in the opposite direction, and the two rotating shafts 405 drive the covering wheel 406 to retract inward, which increases the soil penetration depth. The covering wheel 406 takes more soil from the furrow, thickens the soil covering on both sides of the mulch film, and relies on the weight of the covering soil to compact the film edges, increase the adhesion between the mulch film and the soil, resist crosswinds in the field, and prevent the mulch film from running or lifting. At the same time, the controller 205 controls the electric cylinder 402 to retract, the sealing plate 404 moves away from the discharge port of the pressing cylinder 417, and the pressing cylinder 417 drops soil normally, covering a thin layer of loose soil above the mulch film planting point, which not only fixes the middle of the mulch film, but also helps to cover the corn seeds and retain moisture.

[0050] Specifically, when using this device:

[0051] First, the tractor pulls the entire machine forward at a constant speed, the film-covering frame 203 rotates at a constant speed, the Hall sensor 318 provides a stable speed signal, the controller 205 determines that the implement is in a stable operating state, the electric telescopic rod 309 on the mounting frame 301 remains in the neutral position, the hydraulic oil in the storage box 307 is pressed into the piston cylinders 316 on both sides through the delivery pipe 311, the rotary motor 312 drives the connecting gear 313 to rotate at a constant speed, thereby driving the rack plate 315 meshing with it to move, and then the rack plate 315 drives the moving plate 314 to move towards each other. The piston cylinder 316 moves synchronously to slide on the side closest to the piston, which in turn causes the friction frame 317 to contact the outer wall of the roller 305, thereby applying a certain frictional resistance. At the same time, the rotating motor 306, in conjunction with the fixed plate 304, drives the roller 305 to release the mulch film at a preset speed. The mulch film is pulled and laid flat on the ridge formed by the ridging device 202 by the mulching frame 203. The plowing device 201 on the inner side of the frame 1 pre-breaks the compacted soil clods to provide a flat base for ridging and mulching. The seeder 204 follows the mulching process and precisely punches holes in the middle of the mulch film to drop the seeds, completing the corn planting.

[0052] Then, when the machine experiences bumps, jams, and sudden deceleration while compacting hard soil clods, the rotational speed of the film covering frame 203 drops sharply due to ground resistance. The Hall sensor 318 collects the low-speed signal and feeds it back to the controller 205. The controller 205 then issues a command to drive the electric telescopic rod 309 at the lower end of the connecting frame 308 to extend downwards, pushing the extrusion plate 310 down to press down the hydraulic oil inside the storage box 307. The hydraulic oil then flows under high pressure into the left and right piston cylinders 316 through the two conveying pipes 311. At this time, the resistance on the roller 305 increases, thereby slowing down the rotational speed and immediately reducing the amount of film pulled out. This prevents the film from being unrestrainedly unwound, accumulating, wrinkled, or collapsing due to machine stagnation or traction failure. To prevent potential problems like film curling and wind-induced film removal, the machine resumes normal travel speed after overcoming protruding hard soil clods. The rotation speed of the film covering frame 203 returns to the rated value, and the Hall sensor 318 sends an acceleration signal to the controller 205. The controller 205 controls the electric telescopic rod 309 to retract, pulling the extrusion plate 310 upward. The internal pressure of the storage box 307 decreases, and the hydraulic oil inside the piston cylinder 316 flows back to the storage box 307, reducing frictional resistance. As a result, the roller 305 rotates rapidly under the drive of the rotating motor 306, accelerating the film release speed and matching the machine's travel speed. This prevents the film from being stretched too tight, overloaded, or torn, or broken at the edges.

[0053] Furthermore, the upper end of the connecting rod 401 is fixed to the extrusion plate 310, and the lower end is connected to the toothed plate 403. The toothed plate 403 slides vertically within the groove 12 of the frame 1 by means of the T-shaped plate 11, ensuring that the lifting and lowering movements do not deviate. During the machine jamming and deceleration, and the downward movement of the extrusion plate 310, the connecting rod 401 simultaneously pulls the toothed plate 403 downward, causing the toothed plate 403 to mesh downward with the mounting gear 416. This causes the mounting gear 416 to drive the rotating column 414 to rotate inside the bearing bracket 413, thereby causing the second conical wheel 415 at the end of the rotating column 414 to mesh with the first conical wheel 412. This causes the rotating shaft 405 connected to the first conical wheel 412 to rotate slightly, so that the rotating shaft 405 drives the rotating shaft 408 and the transmission gear 411 to operate in conjunction through the connecting wheel 409 and the belt 410. This causes the transmission gear 411 to mesh with the fixed gear 407, achieving a synchronous slight deflection of the other set of rotating shafts 405. The soil-covering wheels 406 at the bottom of the two rotating shafts 405 expand outward, the inclination angle decreases, the amount of soil inserted and removed decreases, and the thickness of the soil covering on both sides of the mulch film becomes thinner, reducing the squeezing and pulling of the soil on the low-speed taut mulch film, preventing the heavy pressure of the soil covering from tearing the edges of the mulch film. Under synchronous operation, pressing... The built-in electric cylinder 402 of cylinder 417 extends, pushing the sealing plate 404 to seal the soil outlet of the pressing cylinder 417 under the sealing protection of the rubber sleeve 13. This significantly reduces the amount of soil falling into the middle of the mulch film on the ridge surface, avoiding excessive soil pressure that could damage the film. The soil inside the pressing cylinder 417 is pushed into the pressing cylinder 417 by the covering wheel 406, thus pressing the soil on the top of the mulch film. Similarly, when the equipment returns to normal and suddenly accelerates, the pressing plate 310 rises, and the connecting rod 401 drives the toothed plate 403 to slide upward, driving the mounting gear 416 and the rotating column 4 in the opposite direction. 14. Reverse rotation causes the two rotating shafts 405 to drive the covering wheel 406 to retract inward, increasing the soil penetration depth. The covering wheel 406 takes more soil from the furrow, thickening the soil covering on both sides of the mulch film. The soil covers the edges of the film by their own weight, increasing the adhesion between the mulch film and the soil, resisting crosswinds in the field, and preventing the mulch film from running or lifting. At the same time, the controller 205 controls the electric cylinder 402 to retract, the sealing plate 404 moves away from the discharge port of the pressing cylinder 417, and the pressing cylinder 417 drops soil normally, covering a thin layer of loose soil above the planting point of the mulch film. This not only fixes the middle of the mulch film but also helps to cover the corn seeds and retain moisture.
