Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and in particular to a ground film laying device for agricultural planting. Background Art

[0002] Ground film is a ground covering film, which is usually transparent or black film, but also green and silver film. It is used to cover the ground to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. It promotes plant growth. For those newly unearthed seedlings, it protects the roots and promotes growth.

[0003] There are many existing technologies for film laying devices, such as:

[0004] Chinese patent publication number CN216218621U discloses a mulch film laying device for agricultural planting, including a first oil cylinder, a vehicle body, a frame and a connecting sleeve, a second connecting rod is welded to the right side of the vehicle body, a third connecting rod is movably provided on the top of the second connecting rod, a first oil cylinder is provided on the side of the right side of the vehicle body close to the second connecting rod, one end of the first oil cylinder and one end of the third connecting rod are connected to each other, one end of the third connecting rod is connected to the first connecting rod, and a frame is welded to the bottom of the first connecting rod. This patent realizes that the height of the machine can be adjusted according to actual conditions by providing the first connecting rod, the second connecting rod, the third connecting rod and the first oil cylinder. Therefore, when in use, by starting the first oil cylinder, the first oil cylinder will drive the third connecting rod to rotate, the third connecting rod will drive the second connecting rod to move, and the second connecting rod will drive the frame to move, thereby achieving the purpose of adjusting the height of the machine.

[0005] However, there are still some problems in actual use:

[0006] 1. The current traditional film laying equipment relies heavily on manual labor. During the film laying operation, multiple farmers are often required to coordinate and cooperate with each other to complete the film fixing and laying process. This not only consumes a lot of human resources, but also the degree of cooperation between farmers will affect the laying efficiency and quality.

[0007] 2. To ensure the stability of the mulch film, both sides must be covered with soil to secure it. This process requires farmers to bend over or squat, continuously performing repetitive movements such as shoveling and covering the soil, which greatly increases the intensity of the work. Prolonged work at this high intensity can easily cause fatigue, especially on the waist and back, which can cause a series of physical discomforts.

[0008] In view of this, we propose a mulch film laying device for agricultural planting. Summary of the Invention

[0009] The purpose of the present invention is to provide a ground film laying device for agricultural planting to solve the problems raised in the above background technology.

[0010] The top of the lifting mechanism is connected with the lifting of the lifting mechanism, and the bottom of the lifting mechanism is connected with the lifting of the lifting mechanism, and the lifting of the lifting mechanism is connected with the lifting of the lifting mechanism.

[0011] As a further improvement of the present technical solution, the fixing assembly includes a second cylinder arranged at the end of the convex plate. The piston rod at the end of the second cylinder passes through the convex plate and a pressure plate is provided at the end. When laying the film, the piston rod at the end of the second cylinder is controlled to drive the pressure plate to move to fit the ground.

[0012] As a further improvement of the present technical solution, the bottom of the pressure plate is provided with pressure teeth, which increase the friction of the ground film placed between the pressure plate and the ground. The top of the pressure plate is provided with through holes, which are arranged in an array, and fixing nails are inserted through the through holes to fix the ends of the ground film.

[0013] As a further improvement of the present technical solution, the edge pressing assembly includes a motor arranged under the convex plate, a half gear is provided at the output end of the motor, a first rack is provided on one side of the half gear, and when the half gear rotates, it drives the first rack to reciprocate in the vertical direction, and a edge pressing block is provided at the bottom of the first rack.

[0014] As a further improvement of the present technical solution, the edge pressing block is in the shape of an inverted triangle, and an arc-shaped chamfer is provided at the bottom of the edge pressing block.

[0015] As a further improvement of the technical solution, a column is provided above the first rack, a sliding rod is slidingly provided on the inner wall of the column, the sliding rod is fixed on the top of the first rack, and a telescopic spring is provided between the column and the sliding rod.

[0016] As a further improvement of this technical solution, the burying component includes a second rack arranged on the other side of the half gear, a movable frame is provided below the second rack, a rotating rod is provided inside the movable frame, and the rotating rod passes through the movable frame and rotates inside it.

[0017] As a further improvement of this technical solution, a shovel plate is provided on the surface of the rotating rod, and the shovel plate rotates coaxially with the rotating rod. A torsion spring is provided between the movable frame and the rotating rod, and the rotating rod is driven by the torsion spring to always keep the shovel plate perpendicular to the ground.

[0018] As a further improvement of the present technical solution, a hollow column is provided above the second rack, a long rod is slidingly provided on the inner wall of the hollow column, the long rod is fixed on the top of the second rack, and an elastic member is provided between the hollow column and the long rod.

[0019] As a further improvement of the present technical solution, fixed gears are provided on both sides of the surface of the rotating rod, and a movable rack is provided for sliding above the fixed gear. When the movable rack moves in the vertical direction, it fits with the end of the wedge block. The movable rack moves in the horizontal direction due to the squeezing force of the wedge block. When the movable rack moves, it drives the fixed gear to engage and rotate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the mulch film laying device for agricultural planting, a mobile trolley is moved to the top of the field where the mulch film needs to be laid, and by stretching one side of the mulch film to the side of the field, the piston rod at the end of the second cylinder is controlled to drive the pressure plate to move in the vertical direction, so that the pressure plate presses the ground to fix it on the surface of the field, and the fixing operation can be completed by a single person. By arranging pressure teeth at the bottom of the pressure plate, when the pressure plate moves close to the direction of the mulch film, the pressure teeth first contact the mulch film, and the end of the mulch film is inserted into the soil under the pressure of the pressure teeth, so that the mulch film remains flat during the pressing process. After the pressing is completed, fixing nails are inserted into the through holes in sequence to complete the rapid fixation of the end of the mulch film, thereby improving the working efficiency and ensuring the aesthetics of the mulch film laying.

[0022] 2. In the mulch film laying device for agricultural planting, the motor output shaft is controlled to drive the half gear to rotate, and when the half gear rotates, it drives the first rack to move in the vertical direction. When the first rack drives the edge pressure block to move downward in the vertical direction, the slide bar slides on the inner wall of the column under tension, and at the same time stretches the telescopic spring. At this time, the edge pressure block moves to the surface of the mulch film. When the edge pressure block continues to move downward, the edge pressure block squeezes both sides of the mulch film and presses both sides of the mulch film into the soil, thereby realizing automatic sealing operation on both sides of the mulch film and reducing the labor intensity of the operators.

[0023] 3. In the mulch film laying device for agricultural planting, when the half gear is driven to rotate by the motor output shaft, the half gear drives the second rack to move in the vertical direction. When the second rack moves downward in the vertical direction, the second rack pulls the long rod to slide on the inner wall of the hollow column. The long rod is used to stretch the elastic part during the sliding process. When the second rack moves, it drives the movable frame to move. The shovel plate provided under the movable frame is inserted into the soil in the field. When the movable rack moves to the wedge block, the movable rack is squeezed by the wedge block and moves to the top of the fixed gear. During the movement of the movable rack, it drives the fixed gear to rotate, so that the rotating rod drives the shovel plate to rotate to scatter the soil, so that the soil falls into the groove for automatic filling, and the sealing on both sides of the pressure block is reinforced and sealed, thereby improving the stability of the mulch film.

[0040] The purpose of this embodiment is to provide a device for laying mulch film for agricultural planting, see Figures 1-8As shown, it includes a mobile trolley 100, a placement frame 101 is provided on the top of the mobile trolley 100, an extension arm 102 is provided on one side of the placement frame 101, a convex plate 200 is provided at the bottom of the extension arm 102, a ground film roll 201 is provided on one side of the convex plate 200, connecting plates are provided on both sides of the bottom of the convex plate 200, a wedge block 202 is provided at the end of the connecting plate, and a sorting component is provided at the end of the ground film roll 201. The sorting component includes a first cylinder 203 provided on the top of the convex plate 200, a piston rod at the end of the first cylinder 203 passes through the convex plate 200 and is provided with a frame 204 at the end. A fixed roller 205 is provided inside the body 204, and a movable roller 206 is provided above the fixed roller 205. A compression spring 207 is provided between the movable roller 206 and the frame 204. The movable roller 206 is fitted with the top of the fixed roller 205 by the force of the compression spring 207. A fixing component 300 is provided at the end of the convex plate 200, and the fixing component 300 is used to press the end of the ground film roll 201. A pressing edge component 400 is provided at the center of the convex plate 200, and a soil burying component 500 is provided on one side of the pressing edge component 400. The pressing edge component 400 and the soil burying component 500 move relative to each other.

[0041] Taking into account that at least two workers are required to work together when laying the ground film, one worker fixes the end of the ground film and the other worker lays the ground film, which results in high labor intensity and low efficiency. Therefore, the fixing assembly 300 includes a second cylinder 301 provided at the end of the convex plate 200. The piston rod at the end of the second cylinder 301 passes through the convex plate 200 and a pressure plate 302 is provided at the end. When laying the film, the piston rod of the second cylinder 301 is controlled to drive the pressure plate 302 to move to fit the ground. In the process of laying the ground film, by stretching one side of the ground film to the side of the field, the piston rod at the end of the second cylinder 301 is controlled to drive the pressure plate 302 to move in a vertical direction, so that the pressure plate 302 presses the ground to fix it on the surface of the field. The fixing operation can be completed by one person, reducing collaborative work, thereby improving the efficiency of the ground film laying operation.

[0042] When the mulch is pressed, the mulch is pressed against the ground, and the mulch is not pressed tightly, which causes wrinkles to form during the laying process, thus affecting the aesthetics of the mulch. Therefore, a pressing tooth 303 is provided at the bottom of the pressing plate 302. The pressing tooth 303 increases the friction between the mulch and the ground, and a through hole 304 is provided at the top of the pressing plate 302. The through holes 304 are arranged in an array, and fixing nails are inserted through the through holes 304 to fix the end of the mulch. By providing the pressing teeth 303 at the bottom of the pressing plate 302, when the pressing plate 302 moves to the direction close to the mulch, the pressing teeth 303 first contact the mulch, and the end of the mulch is inserted into the soil under the pressure of the pressing teeth 303, so that the mulch remains flat during the pressing process. After the pressing is completed, the fixing nails are inserted into the through holes 304 in sequence, thereby completing the rapid fixation of the end of the mulch, improving the working efficiency and ensuring the aesthetics of the mulch.

[0043] During the process of laying the ground film, in order to ensure the sealing of the ground film and enable the ground film covering to increase the soil temperature, which helps to increase the ground temperature and thus prevent the crops from being frostbitten, the edge pressing component 400 includes a motor 401 arranged under the convex plate 200, and a half gear 402 is provided at the output end of the motor 401. A first rack 403 is provided on one side of the half gear 402. When the half gear 402 rotates, it drives the first rack 403 to reciprocate in the vertical direction. A edge pressing block 407 is provided at the bottom of the first rack 403. The edge pressing block 407 is provided at the bottom of the first rack 403. 07 is in the shape of an inverted triangle, and the bottom of the edge pressure block 407 is provided with an arc chamfer. A column 404 is provided above the first rack 403, and a slide bar 405 is provided on the inner wall of the column 404 for sliding. The slide bar 405 is fixed on the top of the first rack 403, and a telescopic spring 406 is provided between the column 404 and the slide bar 405. When the end of the ground film is fixed, the mobile trolley 100 is controlled to move in the horizontal direction. During the movement of the mobile trolley 100, the ground film roll 201 is subjected to tension to flatten the surface of the field. In order to avoid the ground film being flattened during the laying process, When the wind blows, it affects the efficiency of film laying. By controlling the output shaft of the motor 401 to drive the half gear 402 to rotate, the half gear 402 drives the first rack 403 to move in the vertical direction. When the first rack 403 drives the edge pressing block 407 to move downward in the vertical direction, the slide bar 405 is pulled and slides on the inner wall of the column 404, and at the same time stretches the telescopic spring 406. At this time, the edge pressing block 407 moves to the surface of the ground film. When the edge pressing block 407 continues to move downward, the edge pressing block 407 squeezes both sides of the ground film, The side pressing blocks 407 are pressed into the soil, thereby realizing automatic sealing operation on both sides of the ground film and reducing the labor intensity of the operators. When the external force on the first rack 403 disappears, the slide bar 405 is driven by the restoring force of the telescopic spring 406 to drive the first rack 403 to move upward in the vertical direction. Since the edge pressing block 407 is in the shape of an inverted triangle, the edge pressing block 407 can quickly move away from the surface of the ground film. When the edge pressing block 407 moves back and forth to press both sides of the ground film, it can ensure the sealing of the ground film during laying and improve the sealing effect.

[0044] When the ground film is pressed and sealed by the pressure block 407, it is necessary to fill the groove formed during the pressing process to improve the stability of the ground film. Therefore, the soil burying component 500 includes a second rack 501 arranged on the other side of the half gear 402, and a moving frame 505 is provided below the second rack 501. A rotating rod 506 is provided inside the moving frame 505. The rotating rod 506 passes through the moving frame 505 and rotates inside it. A hollow column 502 is provided above the second rack 501, and a long rod 503 is slidingly provided on the inner wall of the hollow column 502. The long rod 503 is fixed on the top of the second rack 501. An elastic member 504 is provided between the hollow column 502 and the long rod 503. A shovel plate 507 is provided on the surface of the rotating rod 506. The shovel plate 507 rotates coaxially with the rotating rod 506. A torsion spring 508 is provided between the moving frame 505 and the rotating rod 506. The movable rod 506 is driven by the force of the torsion spring 508 to drive the shovel plate 507 to always be perpendicular to the ground. When the output shaft of the motor 401 drives the half gear 402 to rotate, the half gear 402 drives the second rack 501 to move in the vertical direction. When the second rack 501 moves downward in the vertical direction, the second rack 501 pulls the long rod 503 to slide on the inner wall of the hollow column 502. The long rod 503 is used to stretch the elastic member 504 during the sliding process. When the second rack 501 moves, it drives the movable frame 505 to move. The shovel plate 507 provided under the movable frame 505 is inserted into the soil in the field. By rotating the rotating rod 506, the shovel plate 507 is driven to move, and the field soil on one side of the shovel plate 507 is scattered, so that the scattered field soil falls into the inside of the groove to fill it, thereby reinforcing the seal at both sides of the pressure edge block 407, thereby improving the stability of the ground film.

[0045] When the gear 510 is moved, the shovel 507 is rotated, so that the rotating rod 506 drives the shovel plate 507 to rotate and scatter the soil, so that the soil falls into the groove and is automatically filled, which reduces the labor intensity of the operators and improves the backfilling efficiency.

[0046] During specific use, the mobile trolley 100 is controlled to move to the top of the field where the ground film needs to be laid, and by stretching one side of the ground film to the side of the field, the piston rod at the end of the second cylinder 301 is controlled to drive the pressure plate 302 to move in the vertical direction, so that the pressure plate 302 presses the ground to fix it on the surface of the field, and the fixing operation can be completed by a single person. By providing a pressure tooth 303 at the bottom of the pressure plate 302, when the pressure plate 302 moves close to the ground film, the pressure tooth 303 first contacts the ground film, and the end of the ground film is inserted into the soil under the pressure of the pressure tooth 303, so that the ground film remains flat during the pressing process. After the pressing is completed, fixing nails are inserted into the through holes 304 in sequence, thereby completing the rapid fixation of the end of the ground film, thereby improving the working efficiency and ensuring the aesthetics of the ground film laying;

[0047] When the end of the ground film is fixed, the mobile trolley 100 is controlled to move in the horizontal direction to perform automatic film laying operations. During the movement of the mobile trolley 100, the ground film roll 201 is subjected to tension to flatten the surface of the field. The output shaft of the motor 401 is controlled to drive the half gear 402 to rotate. When the half gear 402 rotates, it drives the first rack 403 to move in the vertical direction. When the first rack 403 drives the edge pressure block 407 to move downward in the vertical direction, the slide bar 405 is subjected to tension to slide on the inner wall of the column 404, and at the same time, the telescopic spring 406 is stretched. At this time, the edge pressure block 407 moves to the surface of the ground film. When the edge pressure block When 407 continues to move downward, the edge pressing block 407 squeezes both sides of the ground film and presses both sides of the ground film into the field soil, thereby realizing automatic sealing operation on both sides of the ground film and reducing the labor intensity of the operators. When the external force on the first rack 403 disappears, the slide bar 405 is driven by the restoring force of the telescopic spring 406 to drive the first rack 403 to move upward in the vertical direction. Since the edge pressing block 407 is an inverted triangle shape, the edge pressing block 407 can quickly move away from the surface of the ground film. When the edge pressing block 407 reciprocates to press both sides of the ground film, it can ensure the sealing of the ground film during laying and improve the sealing effect.

[0048] When the output shaft of motor 401 drives half gear 402 to rotate, half gear 402 drives second rack 501 to move in the vertical direction. When second rack 501 moves downward in the vertical direction, second rack 501 pulls long rod 503 to slide on the inner wall of hollow column 502. Long rod 503 is used to stretch elastic member 504 during the sliding process. When second rack 501 moves, it drives moving frame 505 to move. Shovel plate 507 provided under moving frame 505 is inserted into the soil of the field. When moving rack 510 moves to the wedge block 202, moving rack 510 is squeezed by the wedge block 202 and moves to the top of fixed gear 509. During the movement of moving rack 510, it drives fixed gear 509 to rotate, so that rotating rod 506 drives shovel plate 507 to rotate and scatter soil, so that soil falls into the groove for automatic filling, and at the same time reinforces and seals the sealing parts on both sides of pressure edge block 407, thereby improving the stability of ground film.
