Chipping Device Blade Plate Sloped Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chipping and grinding machines often suffer from inefficiencies due to insufficient upliftment or spacing of the blade from the blade plate, leading to material sticking and jamming during operation.
Innovation Solution
The machine design includes a blade plate with angled, one-side-open slits and blade placements that are sloped to ensure the sharp edges face each other, with the blade length exceeding the plate radius, allowing for improved spacing and reducing material sticking, and features a cover for material entry and exit channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blade is installed close to the blade plate with insufficient upliftment, then the device structure is compact, but material sticks and jams during operation
Solution Approach 1:
The blade placement surface is designed with a slope rather than being flat, creating a dimensional change from 2D to 3D configuration. This sloped surface causes material to naturally slide off the blade sharp edge due to gravity, preventing accumulation and jamming while maintaining a compact overall device structure.
2Productivity
If the blade length is increased beyond the plate radius, then chipping efficiency is improved, but the device dimensions increase
Solution Approach 1:
The blade is designed to rotate dynamically with the drive shaft rather than being stationary. The rotation allows the blade to engage material effectively throughout its extended length beyond the plate radius, maximizing chipping efficiency while the compact housing contains the rotating assembly within a manageable footprint.
3Device complexity
If the blade sharp edge is positioned closer to the plate, then the device is more compact, but material accumulates and jams
Solution Approach 1:
The sloped blade placement surface is pre-configured to create a gravity-driven runoff path for material before it can accumulate and jam. This preliminary geometric configuration prevents material buildup proactively, ensuring continuous operational efficiency without requiring additional active mechanisms.

AI summary
A grinding or chipping device and a method of manufacturing the same is disclosed. A chipping or grinding device generally includes a base having a plurality of U-shaped, I-shaped, or C-shaped metal plates and/or beams, an engine on the base, the engine transmitting drive power to a blade plate at a back portion of the base, and a cover over the blade plate. The chipping or grinding machine advantageously provides improved operation by minimizing and/or eliminating chipped or ground pieces and/or material from becoming stuck or jammed in the device.
