[0002] In agricultural planting, mulching machines are commonly used to lay thin films on the soil to protect the crop's growing environment. In spring and autumn, mulching can effectively prevent cold air from invading, increase the temperature, and provide a greenhouse environment, thus allowing plants to grow healthier. In summer, mulching can provide shade and moisture retention, creating a suitable growing environment. Therefore, mulching machines are widely used in agricultural planting.

[0003] Chinese utility model patent CN222108738U discloses a film-laying machine. This device, during use, uses a ridge width component and other devices to adjust the spacing between two sets of ridge boards, compaction components, and soil-covering components, thereby adjusting the ridge and mulch width according to different crops. However, in actual use, this device can only adjust the ridge and mulch width, but the height cannot be effectively adjusted. Different crops have different requirements for ridge height; for example, some crops need higher ridges to promote drainage, while others need lower ridges to maintain soil moisture. The lack of height adjustment function makes the device unable to adapt to the planting needs of various crops, reducing its versatility and practicality. Therefore, an adjustable film-laying machine is proposed to address the above problems. Utility Model Content

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1-3 An adjustable film laying machine includes a connecting frame 1, a width adjustment mechanism 3, a height adjustment mechanism 1 4 and a height adjustment mechanism 2 5 installed inside the connecting frame 1, a film rod 7 rotatably connected to the lower end of the connecting frame 1, and a compaction wheel 306, a soil covering plate 307 and a ridging plate 308 installed on the outside of the connecting frame 1.

[0028] The width adjustment mechanism 3 includes two sets of double-ended threaded rods 301 rotatably connected to the inner wall of the connecting frame 1. Two sets of slider one 302 and slider two 303 are respectively threadedly connected to the threaded sections of the two sets of double-ended threaded rods 301. A connecting plate 305 is installed on the outer wall of slider one 302, and the outer wall is L-shaped. The compaction wheel 306 and the soil covering plate 307 are both installed on the outer wall of the connecting plate 305. A connecting rod 403 is slidably connected to the outer wall of slider two 303. A ridging plate 308 is installed at the end of the connecting rod 403.

[0029] Furthermore, by means of the rotation of the two sets of double-headed threaded rods 301, the two sets of slider one 302 and slider two 303 can be driven to slide towards or relative to each other, thereby adjusting the width of the two sets of compaction rollers 306, soil covering plate 307 and ridging plate 308 outside the connecting frame 1.

[0030] The height adjustment mechanism 4 includes a rod 501 inserted into the outer wall of the slider 302. The outer wall of the connecting plate 305 has equally spaced insertion holes. The rod 501 is inserted into the corresponding insertion hole. A fixing block 502 is fixedly connected to the end of the rod 501. A spring 503 is sleeved on the outer wall of the rod 501. The two ends of the spring 503 are fixedly connected to the slider 302 and the fixing block 502, respectively.

[0031] Furthermore, by sliding the connecting plate 305 on the outer wall of the slider 302, the height of the soil covering plate 307 and the compaction wheel 306 can be adjusted, and the inserted rod 501 can fix the adjusted height. The elastic force of the spring 503 can ensure the stability of the inserted rod 501 after insertion.

[0032] The height adjustment mechanism 25 includes an electric telescopic rod 401 fixedly connected to the lower end face of the connecting frame 1. A sliding rod 402 is fixedly connected to the telescopic end of the electric telescopic rod 401, and both sets of connecting rods 403 slide on the outer wall of the sliding rod 402.

[0033] Furthermore, by extending and retracting the telescopic end of the electric telescopic rod 401, the slide rod 402 can be driven to slide up and down, simultaneously driving the two sets of ridging plates 308 to slide, thereby achieving the purpose of adjusting the height of the ridging plate 308. The connecting rod 403 is slidably connected to the slide rod 402, thereby avoiding the collision that occurs when the connecting rod 403 slides on the outer wall of the slide rod 402.

[0034] Two sets of sliders 302 are slidably connected to the outer wall of the connecting frame 1. The inner wall of the connecting frame 1 is provided with a slide groove 304. Two sets of sliders 303 slide in the slide groove 304. Two sets of servo motors 2 are fixedly connected to the side wall of the connecting frame 1. The output shaft ends of the two sets of servo motors 2 are respectively coaxially fixedly connected to two sets of double-headed threaded rods 301.

[0035] In practical use, the working principle of this utility model is as follows:

[0036] The operator first adjusts the width and height of the ridging board 308, compaction wheel 306 and soil covering board 307 according to the planting needs of the crops through the width adjustment mechanism 3, the height adjustment mechanism 1 4 and the height adjustment mechanism 2 5.

[0037] Width adjustment process: Two sets of servo motors 2 are started, driving two sets of double-headed threaded rods 301 to rotate synchronously, causing slider one 302 and slider two 303 to slide towards or relative to each other. Slider one 302 drives the compaction wheel 306 and the soil covering plate 307 to move through the connecting plate 305, while slider two 303 drives the ridging plate 308 to move through the connecting rod 403, thereby adjusting the distance between the two sets of compaction wheels 306, soil covering plate 307 and ridging plate 308 to meet the ridge width requirements of different crops.

[0038] Height adjustment process: The operator moves the sliding connecting plate 305 up and down on the outer wall of the slider 302 to adjust the height of the compaction wheel 306 and the soil covering plate 307. After adjustment, the insertion rod 501 is inserted into the corresponding hole on the connecting plate 305. The elastic force of the spring 503 ensures the stability of the insertion rod 501 after insertion, thereby fixing the height of the compaction wheel 306 and the soil covering plate 307.

[0039] Height adjustment of ridging board 308: Activate the electric telescopic rod 401, whose telescopic end drives the sliding rod 402 to slide up and down. Since the two sets of connecting rods 403 are slidably connected to the outer wall of the sliding rod 402, the up and down movement of the sliding rod 402 will synchronously drive the two sets of ridging boards 308 to adjust their height, achieving precise adjustment of the height of the ridging board 308. The sliding connection design between the connecting rod 403 and the sliding rod 402 avoids conflict during movement, ensuring a smooth and reliable adjustment process.

[0040] Film laying process: After adjusting the width and height, the operator installs the film on the film rod 7 and starts the equipment to lay the film. The compaction wheel 306 compacts the ridge surface, the ridging plate 308 forms furrows according to the adjusted height and width, and the soil covering plate 307 covers the soil on the edge of the film, completing the film laying operation. Through the coordinated work of the width and height adjustment mechanism 3, this device can adapt to the requirements of different crops for ridge width and height, improving the flexibility and applicability of the operation.

[0041] In summary, this device, through the coordinated design of width adjustment mechanism 3, height adjustment mechanism 1, and height adjustment mechanism 2, achieves precise adjustment of the width and height of ridging board 308, compaction wheel 306, and soil covering board 307. This solves the problem of the inability to adjust the height of the film laying machine in the background technology, significantly improves the versatility and practicality of the equipment, and provides an efficient and flexible film laying solution for agricultural planting.

[0042] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
