Description

Technical Field

[0001] The utility model relates to the technical field of film mulching machines, in particular to a film mulching machine for new energy agricultural planting. Background Technique

[0002] Film mulching machines for agriculture are widely used in the film mulching process of agricultural planting, realizing mechanized automatic film mulching. Most of the existing film mulching machines are only applicable to one width specification of plastic film; different crop plantings require different width specifications of plastic film, and common ones include 800mm, 1000mm, 120mm, 1500mm, 1800mm, 2000mm, etc. In order to be applicable to plastic films of different width specifications, the frame of the film mulching machine needs to be designed as an adjustable frame; for example, Chinese Patent (authorization publication number CN202503972 U, authorization publication date October 31, 2012) discloses an adjustable agricultural film mulching machine; its technical solution adopts an adjustable frame to realize the adjustment of the length and width of the film mulching machine and the adjustable film mulching operation width; although it expands the applicable range of the film mulching machine for the width of the plastic film; however, the film mulching machine itself does not have power and needs to be driven by a traction device to perform the film mulching operation. Obviously, its technical solution does not consider the problem that the walking wheels of the traction device will interfere with and crush the plastic film when walking in the field. Therefore, when the width of the plastic film is less than the distance between the left and right walking wheels of the traction device, it will inevitably face the problem that the walking wheels of the traction device will crush and interfere with the already laid plastic film, and its applicable range of film mulching width is limited. For example, Chinese Patent (authorization publication number CN 217608645 U, authorization publication date October 21, 2022) discloses a wide-width adjustable film mulching device for lettuce planting; when the device is used, it is also driven to walk by connecting a power device, and there is still the technical problem that the distance between the walking driving wheels of the power device will limit the applicable range of the film mulching width.

[0003] Therefore, how to provide a film mulching machine for new energy agricultural planting, which can realize adjustable film mulching width and the walking driving wheels will not interfere with the already laid plastic film, is an urgent problem to be solved by those skilled in the art.
