Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting equipment technology, specifically relating to a mulch film laying device suitable for vegetable greenhouses. Background Technology

[0002] In greenhouse vegetable cultivation, mulching is an important agronomic measure that can effectively increase soil temperature, maintain soil moisture, reduce weed growth, and promote crop growth and development.

[0003] When laying mulch film in greenhouses, large machinery cannot be used due to the physical structure of the greenhouse, and manual operation is usually required. Because the mulch film is thin and light, it is easy to deform, wrinkle or loosen, which affects the covering effect of the mulch film. Utility Model Content

[0004] To overcome the limitations of the physical structure of greenhouses in the prior art, which prevent the use of large machinery for laying mulch film and often rely on manual operation, the present invention provides a mulch film laying device suitable for vegetable greenhouses. Through the transmission connection between the film-laying mechanism and the traveling wheels, the mulch film maintains uniform tension during laying, avoiding deformation, wrinkles, or loosening, thus ensuring effective coverage. The device has a simple structure, is compact, and easy to operate in vegetable greenhouses; simply pulling the pull frame completes the mulch film laying, making operation simple.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A film laying device suitable for vegetable greenhouses mainly includes a crossbar, a limiting frame, a hand-operated frame, traveling wheels, and a film laying mechanism. The crossbar is installed at the bottom of the hand-operated frame, and a limiting frame for fixing the roll is installed at the end of the crossbar. Traveling wheels are installed on the limiting frame, and the film laying mechanism is installed on the limiting frame and is connected to the traveling wheels for transmission. The film laying mechanism includes an internal gear ring, a gear, a rotating shaft, and a conical top block. The internal gear ring is installed on the traveling wheels and is coaxial with them. The rotating shaft is installed on the limiting frame through a bearing. One end is equipped with a gear that meshes with the internal gear ring, and the other end is equipped with a conical top block that connects with the roll.

[0006] The limiting frame includes a V-shaped support block and a telescopic rod. The crossbar is a hollow square tube structure. The end of the crossbar is fitted with a telescopic rod of the square tube structure that can adjust the spacing of the limiting frame. A knob for fastening the telescopic rod is threaded onto the crossbar. The end of the telescopic rod is perpendicularly connected to the V-shaped support block.

[0007] The hand-operated frame includes a pull rod and a handle. The bottom end of the pull rod is fixed to a crossbar, and the top end is equipped with a handle.

[0008] The beneficial effects of this utility model are:

[0009] This invention uses a film-laying mechanism connected to a traveling wheel to maintain uniform tension during the laying process, preventing deformation, wrinkles, or loosening of the film and ensuring its covering effect. The device has a simple structure, is compact, and is easy to operate in vegetable greenhouses. Simply pull the hand-operated frame to lay the film, making it easy to use.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] This utility model discloses a mulch film laying device suitable for vegetable greenhouses. The mulch film laying device mainly includes a crossbar 1, a limiting frame 2, a hand-operated frame 3, a traveling wheel 4, and a film laying mechanism 5. The crossbar 1 is installed at the bottom of the hand-operated frame 3, and the limiting frame 2 for fixing the roll is installed at the end of the crossbar 1. The traveling wheel 4 is installed on the limiting frame 2. The film laying mechanism 5 is installed on the limiting frame 2 and is connected to the traveling wheel 4 for transmission. The film laying mechanism 5 includes an internal gear ring 501, a gear 502, a rotating shaft 503, and a conical top block 504. The internal gear ring 501 is installed on the traveling wheel 4 and is coaxial with it. The rotating shaft 503 is installed on the limiting frame 2 through a bearing. One end is equipped with a gear 502 that meshes with the internal gear ring 501, and the other end is equipped with a conical top block 504 that connects with the roll.

[0016] In use, the operator first places the traveling wheels 4 of the device in the ditches on both sides of the soil ridge, so that the entire device is positioned above the soil ridge. Then, the roll 6 with the mulch film wound on it is installed on the limiting frame 2. Finally, the first end of the mulch film is pulled out and fixedly buried at the first end of the soil ridge. Then, the hand-pulling frame 3 is pulled to move the device along the ditches. During the movement, the rotation of the traveling wheels 3 will drive the internal gear ring 501 to rotate, which in turn drives the gear 502 to rotate. The gear 502 drives the conical top block 504 to rotate through the rotating shaft 503, thereby continuously pulling the mulch film out of the roll 6 and laying it on the soil ridge. Through the transmission connection between the film laying mechanism 5 and the traveling wheels 4, the mulch film can maintain uniform tension during the laying process, avoiding deformation, wrinkles or loosening of the mulch film. The device has a simple structure and small size, making it easy to operate in vegetable greenhouses. The laying of the mulch film can be completed simply by pulling the hand-pulling frame 3, making the operation simple.

[0017] The limiting frame 2 includes a V-shaped support block 201 and a telescopic rod 202. The crossbar 1 is a hollow square tube structure. The end of the crossbar 1 is inserted with a telescopic rod 202 of the square tube structure that can adjust the spacing between the limiting frames 2. The spacing between the limiting frames 2 can be adjusted according to actual needs to accommodate mulch film rolls of different widths, increasing the versatility of the device and enabling it to meet the laying requirements of mulch film of different specifications. A knob 101 for fastening the telescopic rod 202 is threaded onto the crossbar 1. The end of the telescopic rod 202 is perpendicularly connected to the V-shaped support block 201. The knob 101 can quickly fasten the telescopic rod 202 to ensure that the adjusted position is stable and reliable.

[0018] The hand-operated frame 3 includes a pull rod 301 and a handle 302. The bottom end of the pull rod 301 is fixed to the crossbar 1, and the top end is equipped with a handle 302; this makes it convenient for operators to pull the entire device to move and lay the mulch film.

[0019] Work process:

[0020] In use, the operator first places the traveling wheels 4 of the device in the ditches on both sides of the soil ridge, so that the entire device is positioned above the soil ridge. Then, the roll 6 with the mulch film wound on it is installed on the limiting frame 2. Finally, the first end of the mulch film is pulled out and fixedly buried at the first end of the soil ridge. Then, the hand-pulling frame 3 is pulled to move the device along the ditches. During the movement, the rotation of the traveling wheels 3 will drive the internal gear ring 501 to rotate, which in turn drives the gear 502 to rotate. The gear 502 drives the conical top block 504 to rotate through the rotating shaft 503, thereby continuously pulling the mulch film out of the roll 6 and laying it on the soil ridge. Through the transmission connection between the film laying mechanism 5 and the traveling wheels 4, the mulch film can maintain uniform tension during the laying process, avoiding deformation, wrinkles or loosening of the mulch film. The device has a simple structure and small size, making it easy to operate in vegetable greenhouses. The laying of the mulch film can be completed simply by pulling the hand-pulling frame 3, making the operation simple.
