Abstract
Description
Technical Field
[0001] This utility model relates to the field of forestry machinery technology, specifically to a timber tractor capable of clearing obstacles. Background Technology
[0002] Timber tractors are vehicles specifically designed for transporting timber. They typically consist of a tractor unit and a trailer and can adapt to complex road conditions such as mountainous and forested areas. However, existing timber tractors lack sufficient obstacle removal capabilities. They cannot clear obstacles such as stones and broken logs from the road surface while traveling, causing the timber tractors to be obstructed and requiring manual intervention or detours, thus reducing work efficiency. In addition, due to the lack of protective structures, the frame, tires, and other components of timber tractors are directly exposed to the outside. Timber slippage is inevitable during timber production operations, making them prone to damage from impacts, leading to increased equipment failure rates and maintenance costs. Utility Model Content

Tires are provided on both sides of the frame. The pusher mechanism includes a pusher and a first hydraulic cylinder connected between the pusher and the frame. The pusher is used to clear obstacles when the timber tractor is in motion. The protective mechanism includes a protective plate arranged vertically on the tires and the rear of the frame. The protective plate is used to prevent the tires and the frame from being impacted by timber during timber production operations.
