Solution Overview
Problem
Existing aggregate and gravel spreading machines are limited by small container volumes, increased transport load, and reduced performance when spreading fine gravels, lacking the capacity and speed for uniform and high-volume material distribution.
Innovation Solution
A caterpillar track machine implement with laterally arranged tracks, an arrowhead-shaped spreader structure, height-adjustable attachment points, and counterweights, allowing for easy assembly and disassembly, and enabling high-speed, uniform spreading of aggregates with enhanced structural stability and transport efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional gravel spreading machine with a container is used, then it can spread fine gravels, but the container volume is limited and transport load increases
Solution Approach 1:
The invention extracts the material storage function from the spreading machine itself by using a separate truck to transport and supply aggregates. The spreading machine only contains the spreading mechanism without a large container, thus eliminating the limitation of container volume and reducing transport load while maintaining the ability to spread large volumes of material.
Solution Approach 2:
The spreading machine is designed with universal applicability to work with various types of caterpillar track machines (excavators, backhoes, etc.) through standardized attachment means. This multi-functionality allows the same spreading mechanism to be used with different power sources and transport configurations, optimizing both volume capacity and transport efficiency.
2Manufacturing precision
If the spreader structure is made height adjustable, then spreading uniformity improves, but device complexity increases
Solution Approach 1:
The spreader structure incorporates height adjustment capability that allows it to adapt dynamically to different ground conditions and spreading requirements. The structure can be raised or lowered relative to the caterpillar tracks to maintain optimal spreading geometry across varying terrain, thereby improving spreading uniformity while the adjustment mechanism is designed to be integrated and manageable.
3Productivity
If the implement is designed for easy assembly and disassembly, then transport efficiency improves, but attachment reliability may decrease
Solution Approach 1:
The implement is divided into modular segments including the upper structure, spreader structure, and attachment means that can be independently assembled and disassembled. This segmentation allows rapid attachment and detachment from different caterpillar track machines while each connection point is designed with reliable mechanical features such as pins, brackets, and alignment elements that ensure secure attachment during operation.

AI summary
The present invention relates to an implement of a caterpillar track machine for spreading gravels, aggregates or the like. The implement comprises: two laterally arranged caterpillar tracks (6) and (7) having in their inner face protection and support means (6.1) and (7.1) for an upper structure (1) which provides support to an arrowhead-shaped spreader structure (9) arranged in the lower portion with respect to the upper structure; attachment means for attaching both the upper structure and the spreader structure with the machine on which the implement is to be assembled; adjustment means for adjusting the relative height of the spreader structure (9) with respect to the upper structure (1), and therefore the level or height at which the material to be spread is to be left, hydraulic actuating means. An implement which can be easily assembled and disassembled allowing transport in a conventional trailer or truck is obtained; a significant increase in the performance and speed of spreading gravels, aggregates and the like is also obtained.
