Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, and specifically relates to a film-laying machine for planting. Background Technology

[0002] In planting processes, such as vegetable cultivation, mulching technology is a key measure to increase crop yield, reduce weed growth, and retain soil moisture. Its core lies in using a mulching machine to smoothly and tightly cover the furrow surface, ensuring the edges of the mulch adhere fully to the soil. With the development of agricultural mechanization, various types of vegetable mulching machines have been widely used in field operations, but existing technologies still have the following shortcomings in practical applications: Existing mulch-laying machines typically employ independent manual control structures for adjusting the tilling depth and film pressing height: the height of the tilling plow needs to be adjusted manually by turning bolts or levers, while the pressure of the film pressing wheel requires a separate adjustment by turning a handle. These two adjustment steps are separate and lack a linkage mechanism. This "step-by-step adjustment" mode presents two major problems: firstly, low adjustment efficiency, requiring operators to repeatedly stop the machine and bend over; secondly, poor synchronization accuracy, with deviations easily occurring between the tilling depth and film pressing height. This results in the film edges not being precisely pressed into the furrows created by tilling, and after laying, the sides of the film are prone to warping or displacement due to wind, irrigation water erosion, or soil settlement. In severe cases, secondary manual re-pressing is required, increasing labor costs. Utility Model Content

[0003] This application provides a film-laying machine for planting, which realizes the linkage adjustment of soil turning depth and film pressing height through adjustment components, so as to solve the problems of unstable film laying, low adjustment efficiency and cumbersome operation caused by the separation of soil turning depth and film pressing height adjustment.

[0004] To achieve the above objectives, this application provides a film-laying machine for planting, including a frame. On both sides of the frame, there are soil-turning components provided by support rods, and a film-pressing mechanism provided by L-shaped support plates. A traveling wheel is rotatably provided on the side of the support rod away from the soil-turning components. The frame is also provided with an adjustment component and a film-laying roller. The adjustment component is connected to the film-pressing mechanism and the soil-turning components.

[0005] The adjustment assembly includes a mounting base fixedly mounted on the vehicle frame. A telescopic adjustment rod is rotatably mounted on the mounting base. The end of the telescopic adjustment rod away from the mounting base is connected to the film pressing mechanism. A swing arm is mounted on the connecting shaft between the telescopic adjustment rod and the mounting base. An electric push rod is rotatably mounted on the end of the swing arm away from the telescopic adjustment rod. The electric push rod is rotatably mounted on the vehicle frame. A slot is formed through the end of the telescopic adjustment rod near the mounting base. A linkage rod is rotatably mounted in the slot through a first bearing seat. The end of the linkage rod away from the mounting base is connected to the soil turning assembly.

[0006] In one embodiment, the soil-turning assembly includes a slide rail formed on the support rod, a connecting rod slidably disposed within the slide rail, a soil-turning plow disposed at the end of the connecting rod away from the support rod, and the connecting rod being rotatably connected to the linkage rod via a second bearing.

[0007] In one embodiment, the film pressing mechanism includes a vertical slide rail extending through the L-shaped support plate, a slider slidably disposed within the vertical slide rail, a film pressing wheel rotatably disposed on the slider, and the end of the film pressing wheel away from the slider being rotatably connected to the telescopic adjustment rod.

[0008] In one embodiment, the slide rail is a T-shaped rail, and the vertical slide is an I-shaped rail.

[0009] In one embodiment, the vehicle frame is provided with a soil covering assembly, the soil covering assembly including a limiting seat fixedly disposed at one end of the vehicle frame near the pressing mechanism, a sliding rod slidably disposed within the limiting seat, and a soil covering wheel rotatably disposed on the sliding rod.

[0010] In one embodiment, the limiting seat is bolted to the vehicle frame.

[0011] In one embodiment, a connecting frame is fixedly provided on the side of the vehicle frame away from the soil covering component, and a column is provided on the connecting frame by means of threads.

[0012] Compared with the prior art, the beneficial effects of this application are: The electrically driven linkage adjustment structure achieves synchronous height adjustment of the film pressing mechanism and the soil turning mechanism through adjustment components: the electric push rod extends and retracts, driving the swing arm to rotate around the mounting base, which in turn drives the telescopic adjustment rod to deflect, synchronously linking the working height of the film pressing wheel (sliding along the vertical slide rail via a slider) and the soil turning plow (sliding along the slide rail via a linkage rod driving the connecting rod). This synchronous adjustment mechanism can adjust the soil turning depth and film pressing force in real time according to the flatness of the land, soil hardness, and the depth requirements of vegetable planting furrows, ensuring that both sides of the mulch film are accurately pressed into the furrows formed by soil turning, solving the problems of mulch film edge lifting, wind or irrigation displacement caused by the mismatch between soil turning and film pressing depth in traditional equipment.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] See Figures 1 to 4 As shown, the film-laying machine for planting provided in this application includes a frame 1. On both sides of the frame 1, there are soil-turning components provided by support rods 9, and a film-pressing mechanism provided by L-shaped support plates 7. On the side of the support rods 9 away from the soil-turning components, there are rotatable wheels 3. The frame 1 is also provided with an adjustment component 6 and a film-laying roller 2. The adjustment component 6 is connected to the film-pressing mechanism and the soil-turning components.

[0018] Before using the mulching machine, the working height of the pressing mechanism and the turning mechanism can be adjusted synchronously by adjusting component 6 according to the flatness of the land and the planting needs. This ensures that the two sides of the mulch film are tightly attached to the furrows formed by the turning mechanism under the action of the pressing mechanism, thereby achieving the flatness and stability of the mulch film and reducing the displacement of the mulch film caused by wind or irrigation.

[0019] First, the plastic film roll is installed on the film-laying roller 2, and one end of the film is laid on the ground after passing around the film-pressing mechanism, and the film is pressed and fixed. Then, the film-laying machine is driven forward by the drive equipment. During the movement, the frame 1 moves forward with the assistance of the traveling wheels 3. The soil-turning component turns the soil along the direction of travel to form furrows. At the same time, the plastic film is gradually unfolded and covered on the surface of the furrows as the frame 1 moves. The plastic film covering the surface of the furrows is pressed into the furrows by the film-pressing mechanism, so that both sides of the plastic film are tightly attached to the furrows, ensuring that both sides of the plastic film are completely inside the furrows.

[0020] The adjustment component 6 includes a mounting base 61 fixedly mounted on the frame 1. A telescopic adjustment rod 64 is rotatably mounted on the mounting base 61. The end of the telescopic adjustment rod 64 away from the mounting base 61 is connected to the film pressing mechanism. A swing arm 62 is mounted on the connecting shaft between the telescopic adjustment rod 64 and the mounting base 61. An electric push rod 63 is rotatably mounted on the end of the swing arm 62 away from the telescopic adjustment rod 64. The electric push rod 63 is rotatably mounted on the frame 1. A slot 65 is formed through the telescopic adjustment rod 64 at the end near the mounting base 61. A linkage rod 67 is rotatably mounted in the slot 65 through a first bearing 66. The end of the linkage rod 67 away from the mounting base 61 is connected to the soil turning component.

[0021] When adjusting the film pressing mechanism and the soil turning assembly, the electric push rod 63 is first activated. The telescopic movement of the electric push rod 63 drives the swing arm 62 to rotate around the connecting shaft, which in turn causes the telescopic adjustment rod 64 to move up and down and telescopically. This causes the film pressing mechanism to adjust its height relative to the frame 1. At the same time, the up and down movement of the telescopic adjustment rod 64 is transmitted to the soil turning assembly through the linkage rod 67, allowing the soil turning assembly to complete its height adjustment synchronously. By controlling the telescopic movement of the electric push rod 63, the working depth of the film pressing mechanism and the soil turning assembly can be adjusted synchronously, ensuring that the film laying depth is consistent and adaptable to different terrain conditions, thus improving the efficiency and quality of the mulching operation.

[0022] Optionally, the soil turning assembly includes a slide rail 12 opened on the support rod 9, a connecting rod 11 slidably disposed in the slide rail 12, a soil turning plow 10 disposed at the end of the connecting rod 11 away from the support rod 9, and the connecting rod 11 is rotatably connected to the linkage rod 67 through a second bearing.

[0023] In this embodiment, during the specific adjustment process, when the electric push rod 63 is started and retracts, it drives the swing arm 62 to rotate relative to the end closest to the walking wheel 3. At this time, the telescopic adjustment rod 64 deflects upward, thereby driving the pressing mechanism to move upward. At the same time, the rise of the telescopic adjustment rod 64 drives the connecting rod 11 to slide upward along the slide rail 12 through the linkage rod 67, thereby driving the soil turning plow 10 to move upward and reduce the soil turning depth.

[0024] Conversely, when the electric push rod 63 extends, the swing arm 62 rotates away from the traveling wheel 3, the telescopic adjustment rod 64 deflects downward, driving the film pressing mechanism to move downward. At the same time, the linkage rod 67 pushes the connecting rod 11 to slide downward along the slide rail 12, causing the tilling plow 10 to move downward and increase the tilling depth. Through the above adjustment method, the film pressing depth and tilling depth are adjusted synchronously, improving the adaptability and stability of the film laying operation.

[0025] Optionally, the film pressing mechanism includes a vertical slide 8 that passes through the L-shaped support plate 7, a slider 13 that is slidably disposed in the vertical slide 8, a film pressing wheel 4 that is rotatably disposed on the slider 13, and the end of the film pressing wheel 4 away from the slider 13 that is rotatably connected to the telescopic adjustment rod 64.

[0026] In this embodiment, when it is necessary to adjust the working depth of the film pressing mechanism, the extension and retraction control of the electric push rod 63 causes the swing arm 62 to drive the telescopic adjustment rod 64 to deflect. The deflection of the telescopic adjustment rod 64 causes the slider 13 to slide within the vertical slide rail 8, thereby adjusting the height position of the film pressing wheel 4 and realizing the control and adjustment of the compaction depth of the mulch film.

[0027] Optionally, the slide rail 12 is a T-shaped rail, and the vertical slide rail 8 is an I-shaped rail. The T-shaped rail design enhances the stability of the connecting rod 11 during sliding, preventing deviation or wobbling, thereby ensuring the reliability of the tillage plow 10 during adjustment. The vertical slide rail 8 of the I-shaped rail provides good guidance and load-bearing capacity for the slider 13, making it smoother and more stable when sliding up and down, further improving the accuracy and operational stability of the pressure roller 4 during adjustment.

[0028] Optionally, the frame 1 is provided with a soil covering component 5. The soil covering component 5 includes a limiting seat 51 fixedly disposed on one end of the frame 1 near the pressing mechanism. A sliding rod 52 is slidably disposed in the limiting seat 51, and a soil covering wheel 53 is rotatably disposed on the sliding rod 52.

[0029] Optionally, the limiting seat 51 is bolted to the frame 1.

[0030] In this embodiment, the amount of soil covering can be controlled by adjusting the position of the soil covering component 5 according to the depth of the tilling furrows by the tilling component, so as to adapt to the laying requirements of different thicknesses of mulch film. Specifically, when the tilling depth increases, the sliding position of the slide rod 52 in the limiting seat 51 can be adjusted to make the soil covering wheel 53 move down accordingly, thereby increasing the amount of soil covering and ensuring that the mulch film is fully covered and fixed; conversely, when the tilling depth decreases, the soil covering wheel 53 moves up to reduce the amount of soil covering and prevent the mulch film from being overly buried.

[0031] During the specific adjustment process, the staff can adjust the fixed position of the limit seat 51 on the slide rod 52 by turning the bolts on the limit seat 51, so that the slide rod 52 can slide flexibly in the limit seat 51 and be locked in a suitable position.

[0032] Optionally, a connecting frame 14 is fixedly provided on the side of the vehicle frame 1 away from the soil covering component 5, and a column 15 is provided on the connecting frame 14 by means of threads.

[0033] In this embodiment, the frame 1 is connected to the drive device via the connecting frame 14, which then moves the entire device in the field. After the connecting frame 14 is disconnected from the drive device, the column 15 can be adjusted in height to support the entire device.

[0034] It should be noted that the drive equipment is mainly a tractor or similar power machinery, which can provide a stable power source and mobility for the device.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
