Description

Technical Field

[0001] The utility model belongs to the field of film laying machines, and in particular relates to a film laying machine with a film cutting mechanism. Background Art

[0002] A film laying machine is a device used to lay film or plastic film on a surface. It is commonly used in the agriculture, construction and packaging industries. These machines can automatically or semi-automatically lay film on the ground or other surfaces to protect or cover objects.

[0003] When laying ground film, the existing film laying machines often only have the function of laying film. After the ground film is laid, it is often necessary to cut the ground film manually. The film laying machines are usually moved by large mobile vehicles, which greatly affects the safety of the cutting workers. In addition, a soil-breaking structure is often installed at the front end of the machine, through which the soil is turned over to facilitate the laying of the ground film and create the soil surface. The existing soil-breaking structure is often welded and fixed, so it is generally difficult to adjust the position of the soil-breaking structure as needed, which greatly affects the laying effect of the ground film.

[0004] Therefore, in order to solve the problem that when the above-mentioned film laying machine is laying the ground film, since its ground-breaking structure is generally welded and fixed, it is often difficult to flexibly adjust its position as needed, and it is not convenient to cut the laid ground film, a film laying machine with a film cutting mechanism is developed. By adding an electric cutting structure, a lifting ground film adjustment structure, a threaded installation and adjustment soil turning structure, and an up and down adjustable height soil covering structure to the film laying machine, the laying effect and laying efficiency of the device when laying the ground film can be greatly improved, the laid ground film can be cut up and down, and the position of soil turning and covering can be flexibly adjusted.
