Description

Technical Field

[0001] This utility model relates to an integrated machine for weeding and film removal in mountainous areas, belonging to the field of weeding and film removal tools. Background Technology

[0002] Traditional film-removing machines are primarily designed for large-scale farmland in plains areas, and generally suffer from problems such as large size, heavy structure, and poor maneuverability. When operating in complex terrains such as hilly and mountainous areas, due to small plots, steep slopes, and varying soil conditions, existing film-removing machines often struggle to adapt, leading to operational difficulties and low efficiency. Furthermore, large film-removing machines are prone to sideslip or instability when operating on slopes, posing safety hazards and causing severe soil compaction, which may negatively impact crop growth. Due to the lack of lightweight and adaptable designs, residual film collection in hilly and mountainous areas has long relied on manual labor, resulting in high labor intensity, low collection rates, and hindering the development of agricultural mechanization.

[0003] Therefore, there is a need for a machine that integrates weeding and film removal in mountainous areas, which is simple in structure, lightweight, easy to operate, and capable of performing both film removal and weeding tasks. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a mountain weeding and film removal integrated machine with simple structure, lightweight and easy operation, capable of performing film removal and weeding work; it can overcome the shortcomings of the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0017] 3. The positioning device includes a guide hole at the free end of the guide groove, a screw connected to the slider installed in the guide hole, and positioning nuts on the screw on both sides of the guide hole. With this structure, when the transmission belt becomes loose, the slider is moved outward by pulling the screw outward, thereby tightening the transmission belt. After the transmission belt is tightened, it is pre-tightened and positioned by the positioning nuts.

[0018] 4. The positioning device includes a guide hole at the free end of the guide groove, a screw connected to the slider installed in the guide hole, and positioning nuts on the screw on both sides of the guide hole. With this structure, when the transmission belt becomes loose, the slider is moved outward by pulling the screw outward, thereby tightening the transmission belt. After the transmission belt is tightened, it is pre-tightened and positioned by the positioning nuts.

[0019] 5. The positioning screws facilitate the installation and removal of the film release baffle and the driven wheel, making it easy to clean the film after removing the film release baffle. The sleeve of the film release baffle at the outer end of the film peeling roller is located on the outside of the film release baffle. This makes it easy to pull out the film release baffle by hand by the sleeve when residual film covers the outer film release baffle during the film peeling process, thus facilitating subsequent film cleaning.

The film-removing roller 7 is equipped with a film-loosening device that can loosen tangled residual film for easy cleaning. This structure, through the extension arm extending forward by approximately 80cm, transforms forward pulling of the film into backward pulling, effectively reducing the risk of film breakage. The extended film pulling also solves the problem of film being pressed down by tires or weeding blades. The tension adjustment device can solve the problem of the transmission belt 6 becoming loose and slipping during film removal. The film-loosening device can remove residual film, which is beneficial for cleaning up residual film after removal. Moreover, the device has a simple structure, is lightweight, easy to operate, and can handle both film removal and weeding work.

[0030] Furthermore, the tension adjustment device includes a guide groove 8 at the front end of the extension arm 3, a slider 9 installed in the guide groove 8, a bearing that cooperates with the rotating shaft 4 on the slider 9, and a positioning device for the slider 9 on the guide groove 8.
