Rotary Garbage Packer Mechanism to Prevent Wear and Backflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garbage packing mechanisms suffer from abrasive wear on sliding surfaces due to linear movement, leading to high maintenance costs and potential garbage backflow during packing cycles.
Innovation Solution
A garbage packing mechanism utilizing only rotary movements of components, with bearings located outside the garbage zone to reduce abrasive wear, and incorporating a convex separation plate and a sliding beam to prevent garbage spillage, ensuring efficient packing without linear movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If linear movement is used in the garbage packing mechanism, then the packing function is achieved, but abrasive wear occurs on sliding surfaces
Solution Approach 1:
The patent replaces the linear sliding mechanical system with a rotary mechanical system. Instead of using sliding plates that move linearly through the garbage zone, the invention employs rotary levers and cylinders that rotate about fixed axes. This substitution eliminates direct contact between moving components and garbage, thereby preventing abrasive wear on sliding surfaces and reducing maintenance requirements.
Solution Approach 2:
The patent introduces curved movement trajectories through rotary motion instead of linear straight movement. The levers rotate along arcs and cylinders move in curved paths, creating a spheroidality in the motion pattern. This curved motion allows the mechanical components to operate outside the garbage zone while still achieving the packing function, thus avoiding wear from direct garbage contact.
2Productivity
If sliding surfaces are used in the garbage zone, then the packing mechanism functions, but the sliding surfaces experience abrasive wear
Solution Approach 1:
The patent extracts the wear-prone sliding surfaces from the garbage zone by replacing them with rotary components that operate externally. The levers and cylinders are positioned such that their moving surfaces do not enter the garbage container, thereby removing the source of abrasive wear from the system. This extraction allows the packing mechanism to maintain productivity without the need for frequent replacement of wear elements.
3Productivity
If a planar sliding plate is used during packing, then the packing cycle completes, but garbage may fall back out from the container
Solution Approach 1:
The patent employs dynamic rotary motion of levers and cylinders to control garbage containment throughout the packing cycle. The rotary movement allows the pressing surface to dynamically adjust its position and angle, maintaining contact with the garbage container walls while preventing garbage from falling back out. This dynamic control ensures both packing cycle completion and reliable garbage containment without the static limitations of planar sliding plates.

AI summary
The present invention relates to a garbage packing mechanism, more specifically a garbage packer with rotary moving components for a rear-loaded garbage truck. The garbage packer comprises the body of the garbage packer with two side walls, concave bottom and substantially open at the top and rear sides, a gripping, locking, lifting and emptying mechanism of a garbage bin, and a lever (1) attached in a manner that enables rotation to the inner side of each side wall of the rear part of the body of the garbage packer, whereby the levers (1) can be rotated around the attachment points with lever cylinders (3). A press plate (4) enabling rotational movement is attached between the levers. The garbage packer comprises a stationary separation plate (8) with convex profile. A beam (13, 14, 15) with a plate-shaped extension part (16) is attached between the levers (1), wherein the extension part has a front edge (17). The front edge (17) slides during the garbage packing movements along the convex surface of the separation plate (8), whereby the profile of the convex surface matches the movement path of the lever (1), ensuring that during the packing process the garbage contained in the container does not spill back onto the press plate (4).
