Shredder Feed Roller Mechanism for Bulky Clipping Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receiving devices for choppers often experience blockages when handling bulky clippings, such as vine wood or tree cuttings, which hinders optimal shredding and chopping processes.
Innovation Solution
A receiving device with at least two vertically arranged feed rollers rotating in opposite directions, accompanied by additional intake mechanisms like a centrally arranged rotating toothed wheel or movable hook, ensures smooth alignment and feeding of clippings into the chopping device, with an oscillating suspension for one roller to prevent clogging and a transversely arranged rotating pick-up roller to lift ground clippings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hinge guide is used to allow the rear wall to open resiliently when stones or hard dirt are drawn in, then blockages and damage to the chopping device are avoided, but the efficiency of the comminution process is considerably reduced
Solution Approach 1:
The rear wall is designed to be dynamically adjustable between a closed position (for efficient chopping) and an open position (for ejecting foreign objects). The spring element provides automatic transition between these states based on operational conditions, allowing the system to maintain high efficiency while avoiding blockages.
2Ease of operation
If flail choppers are used in vineyards, then they are commonly available and easy to operate, but they are not suitable for precise cutting and uniform length requirements
Solution Approach 1:
The chopping device uses adjustable parameters including knife configuration, rotation speed, and feed rate to achieve precise cutting. The system can be configured with different knife types and arrangements to produce uniform lengths suitable for energy generation, while maintaining ease of operation through standardized mounting and adjustment mechanisms.
3Productivity
If multiple feed rollers are added to handle bulky clippings smoothly, then the intake of clippings is improved and blockages are prevented, but the device complexity increases
Solution Approach 1:
The feed mechanism is divided into multiple independent feed rollers, each responsible for a specific function: one roller for initial pickup of bulky clippings, another for alignment, and a third for feeding into the chopping device. This segmentation allows each roller to be optimized for its specific task while working together to prevent blockages and improve intake efficiency.

AI summary
A shredder is equipped with a receiving device (100) and a shredding device, wherein the receiving device has at least two vertically arranged feed rollers (101, 102) which are designed for counter-rotation and which are intended for transporting material to be shredded into a feed opening for the shredding device located behind the feed rollers. The shredder is characterized in that at least one further feed device (109) is provided in the upper and/or lower region of the receiving area.
