Description

Technical Field

[0001] The utility model relates to the technical field of ground film covering devices, in particular to a film laying device for color-matched ground films. Background Art

[0002] In agricultural production, mulching refers to a measure of covering the ground surface with agricultural plastic film to maintain soil temperature and reduce soil heat loss caused by the temperature difference between day and night. It can also reduce the evaporation of soil moisture, which is conducive to maintaining soil moisture and providing good water and heat conditions for crop growth. There are many types of agricultural mulch films, which are classified by color into black, white, silver-gray, black and white, etc. They can also be divided into degradable mulch films and ordinary PE mulch films. Among them, black mulch film covering can prevent sunlight from reaching the soil surface, thereby inhibiting the photosynthesis and growth of weeds and reducing the competition between weeds and crops. Therefore, the existing black and white multi-color mulch films will be covered according to demand. While the production cost and use cost remain unchanged, the white part is used for crop cultivation. There is no obvious difference between the ground temperature of the roots of the crops in the early stage and the ground temperature of the ordinary white mulch film, which can ensure the early demand for low temperature of the crops. The black mulch film has a better weed prevention effect and can effectively control 80% of the weeds.

[0003] The current ground film laying device generally has a structure as described in a ground film laying device disclosed in patent application number "CN202322475845.3", including a frame, a handrail is fixedly provided on one side of the frame, a walking wheel is installed on one side below the frame, a loosening rake is provided on one side of the walking wheel, a guide covering plate is provided on one side of the loosening rake, a film pressing roller is provided on one side of the guide covering plate, and a ground film roller is provided on the top of the frame. However, the laying function of this utility model is single, and when laying multi-color ground films, multiple laying operations are required, which reduces production efficiency, and is prone to problems such as misalignment, overlap, and gaps between ground films, thereby affecting the heat preservation, moisture retention and insect prevention effects of the ground films.

[0031] like Figure 1 and Figure 2 As shown, a film laying device for a color-matching ground film comprises a film laying assembly, which is detachably connected to the end of an agricultural vehicle 2 through a connecting block 1, and the film laying assembly comprises a ground film roller 3, which is rotatably connected to the connecting block 1, and a first drive motor 4 drives the ground film roller 3 to rotate. When laying the ground film, the agricultural vehicle 2 drives the ground film roller 3 to move forward, the end of the ground film roller 3 is fixed, and the first drive motor 4 drives the ground film roller 3 to rotate, thereby completing the laying of the ground film. Among them, a plurality of anti-skid grooves 14 are evenly provided on the ground film roller 3, thereby increasing the contact area between the ground film and the ground film roller 3, improving the friction between the ground film and the ground film roller 3, preventing the ground film from sliding or shifting on the ground film roller 3, and ensuring that the ground film can be stably transmitted and laid. A bearing 18 is arranged between the connecting shaft 16 and the connecting block 1. Thus, the friction between the ground film roller 3 and the connecting block 1 during the rotation process can be reduced, providing a smooth rotation for the ground film roller 3, and being able to bear the load of the ground film roller 3. The first driving motor 4 drives the ground film roller 3 to rotate through the connecting shaft 16, and the connecting shaft 16 is connected to the ground film roller 3 through the flange 17. Therefore, the ground film roller 3 can be disassembled and replaced at any time according to work requirements, which increases the convenience of work.

By rotating the second positioning rod 12, the second positioning rod 12 is fixedly or slidingly connected to the positioning groove 8, and then the agricultural vehicle 2 drives the ground film roller 3 to move forward, and the film pulling device 21 tightens the ground films of different colors, and then the ground films of different colors are plastic-sealed by the heat sealing device 13 to avoid gaps between the color-matching ground films, and only one laying is required, which increases the laying efficiency, and the color and size can be adjusted according to the requirements of the vegetation, ensuring the heat preservation, moisture retention and insect-proof effects of the ground film. A film pressing roller 20 is rotatably connected to the color-matching component. Then the film pressing roller 20 can press the ground film tightly, so that the ground film fits the ground better, ensures the position of the ground film, enhances the quality of the film laying, and thus ensures the increase of soil temperature and the maintenance of soil moisture.
