Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a mulch film guide rod structure. Background Technology

[0002] Mulch film is a very thin plastic film that is directly applied to the soil surface of farmland in agricultural production. It serves to retain heat and moisture, resist drought, suppress weeds, improve soil structure, increase fertilizer efficiency, and prevent pests and diseases. It is commonly used in agriculture, horticulture, and forestry. The mulch film guide rod structure guides and extends the film, ensuring it is laid flat and tightly against the ground surface.

[0003] However, the width of the ridges in the fields varies, requiring different widths of mulch film. Existing guide rod structures are relatively fixed and cannot be adjusted according to the mulch film width, resulting in different models of mulch film guide rod structures being needed for ridges of different widths. Furthermore, in existing technologies, the mulch film is prone to tilting during the stretching process due to incomplete unfolding, leading to uneven laying or incomplete coverage of the ridges.

[0004] Therefore, this application provides a mulch film guide rod structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mulch film guide rod structure. This device can be adjusted according to the width of the mulch film and can also prevent the mulch film from tilting during the pulling process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A plastic film guide rod structure includes a main board and an outer slide rod. An outer slide frame is fixedly mounted on the lower end face of the main board. A first bracket is fixedly mounted on one side of the outer wall of the outer slide frame. An inner slide frame is slidably mounted inside the other side of the outer wall of the outer slide frame. A second bracket is fixedly mounted on the lower end face of the inner slide frame. A support leg is fixedly mounted at the middle of the front end of both the first and second brackets. A fixing frame is fixedly mounted on the upper end face of both support legs. Limit blocks are fixedly mounted on both sides of the upper end face of the main board. A slide rod is slidably mounted inside the two limit blocks. Limit plates are fixedly mounted on both sides of the outer wall of the slide rod. A fixing plate is fixedly mounted at the front end of the middle of the upper end face of the main board. An inner slide rod is slidably mounted inside one side of the outer wall of the outer slide rod. A fixed limiting sleeve is rotatably mounted on one side of the outer wall of the outer slide rod via a bearing. A threaded sleeve is rotatably mounted on the other side of the outer wall of the inner slide rod via a bearing. The threaded sleeve is threadedly fitted with the threaded limiting sleeve.

[0007] Furthermore, a first connecting block is slidably disposed on the lower end face of the second bracket, and a second connecting block is slidably disposed on the lower end face of the first connecting block.

[0008] Furthermore, fixing blocks are fixedly installed at the lower end face corners of the front and rear ends of the second bracket, at the upper and lower end face corners of the front and rear ends of the first connecting block, and at the upper end face corners of the front and rear ends of the second connecting block. The multiple fixing blocks are fixedly connected by bolts and nuts threadedly engaging. Limiting semicircular rings are fixedly installed on both sides of the inner top surface of the first connecting block and the inner bottom surface of the second connecting block.

[0009] Furthermore, the slide rod has multiple first threaded holes at the center of its front end, and the fixing plate is fixedly connected to the slide rod by bolts threaded into the adjacent first threaded holes.

[0010] Furthermore, rollers are rotatably mounted on the lower end faces of the outer walls of the two support legs via bearings, and two guide wheels are rotatably mounted on the lower end faces of the inner walls of the two fixing frames via bearings.

[0011] Furthermore, the lower end face of the inner slide is provided with a plurality of second threaded holes, and the lower end face of the outer slide is fixedly connected to the inner slide by bolts through threaded engagement with the adjacent second threaded holes on the other side.

[0012] Furthermore, the outer slide rod is rotatably mounted on the lower end of one side of the outer wall of the first bracket via a bearing, and a limit bearing is fixedly mounted on the other side of the outer wall of the inner slide rod. The limit bearing is rotatably mounted between the first connecting block and the second connecting block.

[0013] Furthermore, a tractor connector is fixedly installed at the center of the upper end face of the slide bar.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a mulch film guide rod structure. When using the device, it can be adjusted according to the width of the mulch film. The first and second connecting parts are removed, the mulch film is installed around the outer sliding rod, and one end of the mulch film is placed on the outer periphery of the fixing limiting sleeve near the other end, while the other end is placed on the outer periphery near the other end. Then, the threaded limiting sleeve and the threaded sleeve are threaded together. The position of the inner sliding frame inside the outer sliding frame is adjusted and fixed with bolts. Finally, the threaded limiting sleeve is tightened.

[0015] 2. The mulch film guide rod structure proposed in this utility model allows the mulch film to be unfolded and passed through the space between two adjacent guide wheels among the four guide wheels. During the pulling process of the mulch film, the guide wheels can prevent the mulch film from folding back towards the center. All guide wheels can rotate, which can prevent the mulch film from sticking to the guide wheels and tearing during pulling. Attached Figure Description

Tighten the threaded limiting sleeve 19 to the outer wall of the threaded sleeve 17 via threaded engagement. Then, place the limiting bearing 18 between the first connecting block 22 and the second connecting block 23, positioned between the four limiting semicircular rings 24. Fix the adjacent fixing blocks 25 using bolts and nuts, thus fixing the first connecting block 22 and the second connecting block 23 together. Then, fix the adjacent fixing blocks 25 using multiple nuts and bolts, thus fixing the first connecting block 22 and the second bracket 13 together. Adjust the position of the inner slide 20 inside the outer slide 2 according to the width of the mulch film. After adjustment, fix the outer slide 2 and inner slide 20 by threading the bolts into the second threaded hole 21. Then tighten the threaded limit sleeve 19 to prevent the mulch film from sliding left and right. Loosen the bolts at the front end of the fixing plate 9, slide the slide rod 10 to center the mulch film in the device, and then fix the fixing plate 9 and slide rod 10 by threading the bolts into the first threaded hole 11. Pull the mulch film out smoothly, and simultaneously pull it out from between two adjacent guide wheels 7 of the four guide wheels 7. Connect the tractor connector to the tractor, lay the mulch film on the ground, and cover it with soil to press it down. The two rollers 5 can support the device and reduce friction when it moves.

[0022] Specifically, the position of the inner sliding rod 14 within the outer sliding rod 16 can be adjusted according to the width of the mulch film to provide better support. The inner sliding frame 20 and outer sliding frame 2 can be fixed by bolts engaging with the second threaded hole 21, thus restricting the second support 13 from moving independently. The four limiting semicircular rings 24 inside the first connecting block 22 and the second connecting block 23 can clamp the limiting bearing 18 to prevent loosening, thus restricting the inner sliding rod 16 to rotate only and not slide left or right. The threaded limiting sleeve 19 and threaded sleeve 17 threadedly engage to fix the limiting sleeve 15, preventing the mulch film from sliding left or right, allowing only rotation. Fixing the limiting sleeve 15 and threaded sleeve 17 supports the mulch film, preventing imbalance on both sides. The mulch film can be replaced by unscrewing the bolts and nuts on the multiple fixing blocks 25 and removing the first connecting block 22 and the second connecting block 23.
