Semi-mounted plough wheel cleaning unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-mounted plows with support wheels face issues with clogging during U-turn maneuvers and transport due to the fixed cleaning member interfering with movement and accumulating debris, leading to potential rotation blockages.
Innovation Solution
The cleaning member is positioned in the rear and lower quarter of the support wheel, linked to the frame via a connecting device, allowing it to maintain a consistent height relative to the ground and operate independently of the carriage, preventing interference during U-turns and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning member is rigidly fixed to the carriage, then it can clean the support wheel effectively during plowing, but it approaches the ground during U-turn maneuvers and accumulates debris that blocks wheel rotation
Solution Approach 1:
The cleaning member is separated from the carriage and repositioned to be linked directly to the frame, creating functional independence. This segmentation allows the cleaning member to maintain its cleaning function while eliminating interference with carriage movement during U-turn maneuvers.
Solution Approach 2:
A connecting device serves as an intermediary between the frame and the cleaning member, allowing the cleaning member to be positioned in the rear and lower quarter of the support wheel while maintaining its cleaning effectiveness without being rigidly attached to the carriage.
2Reliability
If the cleaning member is positioned in the rear and lower quarter of the support wheel and linked to the frame, then it maintains consistent height during maneuvers, but requires a complex connecting device
Solution Approach 1:
The connecting device serves multiple functions: it links the cleaning member to the frame, allows relative movement during U-turns, maintains consistent cleaning position, and absorbs carriage position changes. This multi-functionality reduces the need for additional separate mechanisms.
3Reliability
If the cleaning member operates close to the ground in the rear and lower quarter, then it prevents debris accumulation on the wheel, but debris is drawn upwards by wheel rotation and deposited on the frame
Solution Approach 1:
The cleaning member is specifically positioned in the rear and lower quarter of the support wheel, targeting the area most prone to debris accumulation. This localized cleaning approach effectively prevents wheel blockage while minimizing debris抛向 the frame.

AI summary
The plough (1) has a support wheel (8) connected to a frame (6) via a carriage (9), where the frame is provided with a ploughing body (7). The support wheel rolls on the soil by pivoting around a horizontal wheel axle (10). The support wheel comprises a cleaning unit (12) that extends in lower and quarterback of the support wheel, transverse to a forward direction (A). The cleaning unit is connected to the frame by a connection device (13) e.g. electric or hydraulic connection system. The cleaning unit is articulated with the wheel axle of the support wheel.
