Adjustable Frame Shredder for Stable Road Transport

Solution Overview

Problem

Existing agricultural shredder devices attached to tractor vehicles face challenges with high mass and lifting power requirements due to large shredding boxes, leading to instability during road transport and the need for powerful towing vehicles.

Innovation Solution

The device features a frame with maneuvering means allowing vertical movement of the rear axle and front drawbar, enabling a low position for road transport stability and an intermediate position for shredding, with hydraulic cylinders and scissor-type mechanisms for precise height adjustment of shredding boxes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If large shredding boxes are used to increase processing width and productivity, then the device mass increases, but the towing vehicle requires substantial lifting power and ballasting

Engineering Contradiction:

Improveprocessing widthVSAvoiddevice mass

Core Design Contradiction:

ProductivityVSWeight of moving object

Solution Approach 1:

The patent applies dynamics by making the frame height adjustable relative to the ground. The frame can be positioned in a first height configuration during shredding operations to maximize processing width and productivity, then raised to a second, higher configuration during road transport to reduce the center of gravity and improve stability. This dynamic reconfiguration allows the same device to optimize for different operational modes without requiring separate equipment.

Inventive Principle:

Principle #15Dynamics

2Productivity

If large shredding boxes are used to increase processing width, then productivity improves, but road transport stability deteriorates

Engineering Contradiction:

Solution Approach 1:

The patent applies dynamics by making the frame height adjustable relative to the ground. The frame can be positioned in a first height configuration during shredding operations to maximize processing width and productivity, then raised to a second, higher configuration during road transport to reduce the center of gravity and improve stability. This dynamic reconfiguration allows the same device to optimize for different operational modes without requiring separate equipment.

AI summary

The device (1) has a central shell carried by a chassis (2) along an extension of the chassis, and a lateral shell (3) carried by the chassis. A rear axle (6) cooperates with the chassis through operating units, where the device is operated in an inactive state, in which the shells are raised at a distance from a ground, for traveling on a road, and is operated in an active state, in which the shells are conveyed into an active position and arranged close to the ground, for tearing/grinding of plants.
