Tractor-Mounted Brush Clearing Assembly with Sliding Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clearing devices require users to dismount a tractor to remove brush from the ground, which is inefficient and inconvenient.
Innovation Solution
A clearing device comprising a mounting unit coupled to a tractor with a hooking unit that engages and slides along the bush trunk, allowing the tractor to draw and remove the bush without user dismounting, utilizing a hooking mechanism that biases to centrally position and grip the trunk for extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional clearing device is used, then brush can be removed from the ground, but the user must dismount the tractor which reduces efficiency and convenience
Solution Approach 1:
The patent combines the clearing function with the tractor operation by mounting the clearing device on the tractor. The mounting unit attaches the clearing mechanism to the tractor frame, allowing the tractor to serve dual purposes: transportation and brush clearing. This eliminates the need for the operator to dismount while maintaining effective brush removal capability.
Solution Approach 2:
The clearing device is designed to be self-operating once mounted on the tractor. The tractor's forward motion automatically drives the clearing mechanism through the brush, and the reel mechanism automatically winds and extracts the cleared brush without requiring manual intervention. The operator simply needs to steer the tractor while the system handles the clearing operation autonomously.
2Reliability
If the hooking unit engages and slides along the trunk, then the bush can be gripped and extracted, but the mechanism requires precise lateral movement control
Solution Approach 1:
The hooking unit is designed with movable hooks that can laterally slide along the trunk of the brush. This dynamic capability allows the hooks to adapt to varying trunk positions and diameters. The lateral movement is guided by the mounting unit structure, which provides tracks or guides that constrain the motion to a controlled path, ensuring reliable engagement without requiring complex control systems.
Solution Approach 2:
The mounting unit acts as an intermediary structure between the tractor and the hooking mechanism. It provides the lateral guidance and support for the hooking unit's movement, translating the tractor's forward motion into the appropriate lateral sliding action of the hooks. This intermediary structure simplifies the overall control requirements by providing mechanical guidance rather than requiring active control systems.

AI summary
A brush clearing assembly includes a mounting unit that may be coupled to a tractor. A hooking unit may be coupled to the tractor thereby facilitating the tractor to draw the hooking unit. The hooking unit is movably coupled to the mounting unit. The hooking unit may engage a trunk of a bush when the tractor backs toward the bush. The hooking unit slides laterally in the mounting unit when the hooking unit engages the trunk of the bush. Thus, the hooking unit slides along the trunk of the bush until the hooking unit passes beyond the trunk of the bush. The hooking unit removes the bush when the tractor drives forwardly from the bush.
