AI Technical Summary
The towing frames of existing sanitation bulldozers are prone to tangling when faced with flexible strips such as plastic film, plastic bags, nylon rope, and hemp rope, as well as rigid strips such as broken steel bars, wire mesh fragments, and scrap metal wire. This leads to increased track resistance, jamming, and increased equipment wear and maintenance costs.
Design a traction structure with anti-winding function, including a left anti-winding frame and a right anti-winding frame, which are set on both sides of the traction assembly, and first and second blocking members are installed at the bottom to prevent the strip-shaped object from contacting and getting tangled in the track. The "figure-eight" distribution of the left and right anti-winding frames forms an enclosed space to avoid tangling.
It effectively prevents strip materials from contacting and getting caught in the tracks and the whole machine, improving the continuity of operation, reducing wear on tracks and key components, reducing equipment maintenance costs, and enhancing operational safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulldozer technology, specifically to a traction structure with anti-winding function for a bulldozer and a bulldozer. Background Technology
[0002] In the field of sanitation operations, sanitation bulldozers are one of the core pieces of equipment. They are generally equipped with a tow hook at the rear to meet traction needs during operations, such as towing garbage trucks and assisting in the handling of heavy waste. This design is currently the mainstream configuration for this type of machine in the industry. However, the operating scenarios of sanitation bulldozers are significantly complex and unique, encompassing two key working conditions: first, garbage removal, which often involves a large amount of flexible strips such as plastic film, plastic bags, nylon rope, and hemp rope. These strips are lightweight and easily entangled, making them highly susceptible to being caught in the tracks during bulldozer operation; second, demolition of old buildings, which generates a large amount of construction waste, including rigid strips such as broken steel bars, wire mesh fragments, and scrap metal. These materials are hard and tough, and once they come into contact with the running tracks, they are even more likely to become stubbornly entangled.
[0003] Existing sanitation bulldozers' drawbars either focus solely on traction or anti-entanglement, failing to address the material entanglement issues in these two scenarios while still providing traction. They lack corresponding protective structures. When strips of plastic, rope, or wire become entangled in the tracks, they roll upwards with the track's rotation, gradually filling the upper track space, increasing track resistance, and even causing jamming. They may also become lodged in the gap between the track and the chassis, continuously wearing down key components such as track links, drive wheels, and guide wheels, exacerbating equipment wear and increasing maintenance costs and downtime.
