[0002] To increase crop yield, in some water-scarce and arid areas, mulch film is often used to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth. This involves using transparent or PE film to cover and maintain the ground.

[0003] Existing plastic film traction and covering devices are connected by welding, which makes it inconvenient to adjust the traction according to the trench spacing and the width of the film, thus affecting the efficiency of assembly and use. How to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a traction and conveying device for agricultural film, which aims to solve the problem that existing traction covering devices are inconvenient to adjust for traction based on the spacing of the ditches and the width of the film.

[0008] Preferably, the bidirectional screw penetrates the inner wall of the first fixing frame and extends to the outer wall of the first fixing frame, and the outer wall of the bidirectional screw is rotatably connected to the inner wall of the first fixing frame through which it is penetrated.

[0009] By adopting the above technical solution, the bidirectional screw can rotate inside the fixed frame.

[0010] Preferably, one end of the bidirectional screw extending to the outside of the fixing frame is fixedly connected to the outer wall of the rotating plate.

[0011] By adopting the above technical solution, the bidirectional screw can be rotated by rotating the rotating plate.

[0012] Preferably, the bidirectional screw passes through the movable ring and extends to the outside of the movable ring, and the bidirectional screw is threadedly connected to the movable ring.

[0013] By adopting the above technical solution, when the bidirectional screw rotates, the moving ring will move under the action of the thread.

[0014] Preferably, the adjustment assembly includes an outer rod, a connector, and a housing. The outer rod is fixedly connected to the outer wall of the fixing frame, the connector is fixedly connected to the bottom of the moving ring, and the housing is fixedly connected to the outer wall of the connector.

[0018] By adopting the above technical solution, when the connector moves, the outer rod will slide inside the outer shell, causing the air pressure inside the connector to change.

[0019] The beneficial effects of this utility model are:

[0020] 1. By rotating the rotating plate, the rotating plate drives the bidirectional screw to rotate, so that the moving ring, under the action of the screw, pushes the film roll support to move through the moving plate, thereby adjusting the distance between the two film roll supports. This allows the film roll supports to support film rolls of different specifications, thus solving the problem that the existing traction covering device is inconvenient to adjust the traction according to the trench spacing and the film covering width.

[0021] 2. When the movable plate moves, the outer rod moves inside the outer shell, which causes a change in the air pressure inside the connector. At this time, the movable plate moves on the outer wall of the connector under the action of air pressure, which can adjust the height of the film roll bracket. Attached Figure Description

[0029] Reference Figures 1-4A traction and conveying device for agricultural film includes a first fixed frame 1, a second fixed frame 2, a third fixed frame 3, a furrow opener 4, a film pressing wheel 5, and a bulldozer 6. The second fixed frame 2 is fixedly connected to the outer wall of the first fixed frame 1, the third fixed frame 3 is fixedly connected to the outer wall of the first fixed frame 1, the furrow opener 4 is installed at the bottom of the second fixed frame 2, the film pressing wheel 5 is rotatably connected to the bottom of the first fixed frame 1, the bulldozer 6 is installed at the bottom of the third fixed frame 3, an adjustment component 7 is provided on the outside of the second fixed frame 2, and an adjustment component 8 is provided at the bottom of the first fixed frame 1.

[0030] Adjustment assembly 7 includes a bidirectional screw 701, a rotating plate 702, a moving ring 703, a moving plate 704, and a film roll support 705. The bidirectional screw 701 is disposed inside the fixing frame 1, penetrating the inner wall of the fixing frame 1 and extending to the outer wall of the fixing frame 1. The outer wall of the bidirectional screw 701 is rotatably connected to the penetrating inner wall of the fixing frame 1, allowing the bidirectional screw 701 to rotate inside the fixing frame 1. The rotating plate 702 is disposed outside the fixing frame 1, and one end of the bidirectional screw 701 extending outside the fixing frame 1 is connected to the rotating plate 705. The outer wall of 02 is fixedly connected, and the bidirectional screw 701 can be rotated by rotating the rotating plate 702. The moving ring 703 is slidably connected to the inside of the fixed frame 1. The bidirectional screw 701 passes through the moving ring 703 and extends to the outside of the moving ring 703. The bidirectional screw 701 and the moving ring 703 are threadedly connected. When the bidirectional screw 701 rotates, the moving ring 703 will move under the action of the thread. The moving plate 704 is set at the bottom of the moving ring 703. The film roll bracket 705 is fixedly connected to the outer wall of the moving plate 704.

[0031] By rotating the rotating plate 702, the rotating plate 702 drives the bidirectional screw 701 to rotate, so that the moving ring 703, under the action of the thread, pushes the film roll support 705 to move through the moving plate 704, thereby adjusting the distance between the two film roll supports 705. This allows the film roll supports 705 to support film rolls of different specifications, thus solving the problem that existing traction covering devices are inconvenient to adjust for traction based on trench spacing and film width.

[0032] The adjusting assembly 8 includes an outer rod 801, a connector 802, and a housing 803. The outer rod 801 is fixedly connected to the outer wall of the fixed frame 1. The connector 802 is fixedly connected to the bottom of the moving ring 703. The bottom end of the connector 802 extends into the interior of the moving plate 704 and is slidably connected to the inner wall of the moving plate 704. The moving plate 704 can move on the surface of the connector 802. When the moving ring 703 moves under the action of the thread, the position of the moving plate 704 can be adjusted by the connector 802. The housing 803 is fixedly connected to the outer wall of the connector 802. One end of the outer rod 801 extends into the interior of the housing 803 and is slidably connected to the inner wall of the housing 803. The interior of the connector 802 is connected to the interior of the housing 803. When the connector 802 moves, the outer rod 801 slides inside the housing 803, causing a change in the air pressure inside the connector 802.

[0033] When the movable plate 704 moves, the outer rod 801 moves inside the outer casing 803, which causes a change in the air pressure inside the connector 802. At this time, the movable plate 704 moves on the outer wall of the connector 802 under the action of air pressure, which can adjust the height of the film roll bracket 705.

[0034] The working principle of this agricultural film traction and conveying device is as follows: When it is necessary to adjust the film roll support 705, the rotating plate 702 is rotated, which drives the bidirectional screw 701 to rotate. At this time, the moving ring 703 will move through the connecting piece 802 to drive the moving plate 704 to move under the action of the thread, and the moving plate 704 will drive the film roll support 705 to move. At the same time, when the connecting piece 802 moves, the outer rod 801 will slide inside the outer shell 803, causing the internal air pressure of the connecting piece 802 to change. At this time, the moving plate 704 will move on the outer wall of the connecting piece 802 under the action of air pressure, thereby adjusting the height of the film roll support 705 until the film roll support 705 is adjusted to the designated position.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
