Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically a device for laying frost-proof mulch film. Background Technology

[0002] In agricultural production, frost-proof mulch is widely used, especially in cold regions or during cold seasons. Frost-proof mulch can effectively increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth.

[0003] To prevent the edges of the mulch film from being blown away by the wind, it is usually necessary to press the soil onto the mulch film. However, traditional frost-proof mulch film laying devices can generally only cover the mulch film on the soil and cannot use the soil to press the mulch film tightly and fix it. Farmers still need to manually press the soil onto the mulch film, which is labor-intensive and affects the laying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a cold-proof mulch film laying device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold-proof mulch film laying device, including a frame, a first fixed frame and a second fixed frame are provided at the lower end of the frame, a movable frame is provided between the first fixed frame and the second fixed frame, a trenching plow is provided at the lower end of both the first fixed frame and the movable frame, a bulldozer plate is provided at the lower end of the first fixed frame and the movable frame, a roller is provided at the side end of the bulldozer plate, a threaded rod is rotatably connected between the first fixed frame and the second fixed frame, a drive motor is connected to the side end of the first fixed frame, and a threaded ring is connected inside the movable frame.

[0008] Preferably, the first fixed frame and the movable frame are respectively connected to support rods on both sides, the trenching plow is connected to the lower end of the front support rod, the bulldozer is connected to the lower end of the rear support rod, and the roller is connected to the rear support rod through a connecting rod.

[0009] Preferably, the drive motor drive end is connected to the threaded rod, the threaded ring is threaded to the outer end of the threaded rod, a guide rail is connected between the first fixed frame and the second fixed frame, and the movable frame is slidably connected to the outer end of the guide rail.

[0010] Preferably, the lower ends of the first fixing frame and the second fixing frame are connected to a connecting plate, a bearing is provided in the connecting plate, a rotating shaft is connected in the bearing, and a ground film roller is sleeved on the outer end of the rotating shaft.

[0011] Preferably, a fixed sleeve is slidably connected to the outer end of the rotating shaft, the side end of the fixed sleeve is connected to the mulch film roll, and a fixing bolt is threaded into the fixed sleeve. The fixing bolt can be connected to the rotating shaft. The lower ends of the first fixed frame and the second fixed frame are connected to a support plate, and a rotating roller is rotatably connected inside the support plate. The mulch film roll is located on the surface of the rotating roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes a trenching plow and a bulldozer. The trenching plow is inserted into the soil, and as the vehicle moves, the two trenching plows dig two trenches in the soil and push the soil to both sides, thus forming two small earthen slopes. The two edges of the mulch film are laid within the two trenches. Then, as the bulldozer passes over the small earthen slopes, it pushes the small earthen slopes back into the trenches, thus pressing the two earthen slopes against the two edges of the mulch film. Roller rollers then press the earthen slopes, thereby pressing the mulch film tightly against the soil on both sides, thus fixing the mulch film and reducing the possibility of the mulch film being blown away or shifted by the wind. Therefore, the device eliminates the need for manual pressing of the mulch film, reducing labor and improving laying efficiency.

[0014] 2. This application incorporates a threaded rod and a threaded ring. Activating the drive motor rotates the threaded rod, which, in conjunction with the threaded ring and constrained by the guide rail, allows the movable frame to move. This enables adjustment of the distance between the movable frame and the first fixed frame, making the device suitable for various widths of mulch film and adapting to different laying requirements. It eliminates the need for specialized laying devices for different mulch film widths, improving the device's versatility and flexibility. Furthermore, operators can quickly adjust the device according to actual needs, saving preparation time and increasing work efficiency.

[0015] 3. This application is equipped with a telescopic cylinder, which can drive the first fixed frame and the second fixed frame to move, thereby adjusting their height. When the device is not in use, the telescopic cylinder can lift the trenching plow, bulldozer blade and roller off the ground, thus facilitating the movement of the device on the road.
