Description

Technical Field

[0001] This utility model relates to the field of agricultural protection equipment technology, specifically to a uniformly winding frame for hail protection nets. Background Technology

[0002] Hail protection nets form an isolation barrier by covering a support frame, which can effectively resist natural disasters such as hail and rainstorms and protect crops.

[0003] Traditional winding methods rely on manual operation, which has significant drawbacks: manual operation can easily lead to localized accumulation and twisting of the net, making it difficult to unwind; the lack of guiding and tension adjustment mechanisms can cause the net to shift or loosen, resulting in loose winding; some equipment requires climbing to operate, which is inefficient and can easily lead to safety accidents.

[0004] While simple winding devices exist in existing technologies, they cannot simultaneously solve the problems of guiding, tension control, and flatness. Therefore, there is an urgent need for a winding device that can achieve uniform winding, safe operation, and a high degree of automation.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes a fixed frame, extrusion rollers, tension rollers, stationary rollers, and winding rollers, with two sets of elastic rubber rollers on the upper and lower sides to bidirectionally extrude the hail protection net, eliminating wrinkles and ensuring a flat and smooth winding surface.
