Middle door guide mechanism of garbage compressor

Abstract

The invention discloses a middle door guide mechanism of a garbage compressor. The middle door guide mechanism comprises guide wheel assemblies mounted on the two sides of a middle door, each guide wheel assembly comprises a guide wheel mounting frame and a guide wheel set mounted on the guide wheel mounting frame, and each guide wheel set is at least composed of two guide wheels located on the same horizontal plane. A synchronous assembly is further included, and comprises a synchronous rod horizontally mounted, a first synchronous gear, a second synchronous gear, a first synchronous rack mounted on a guide column on one side and a second synchronous rack mounted on a guide column on the other side, and the first synchronous gear and the second synchronous gear are mounted on the two endsof the synchronous rod. Through cooperation of the guide wheel assemblies and the synchronous assembly, lifting forces of different hydraulic cylinders on the left side and the right side can be balanced, precise control over the hydraulic cylinders on the two sides is not needed, a nylon guide groove does not need to be additionally designed, and the effect of equalization of the hydraulic lifting force of the left side and the right side of the middle door and the like can also achieved.

Description

technical field [0001] The invention relates to a central door guide structure of a garbage compressor, which belongs to the technical field of vehicle-mounted garbage compressors. [0002] technical background [0003] With the development of environmental sanitation, the demand for compressed garbage bins in cities has increased. The vertical compression garbage compressor is used to compress loose garbage for easy transfer. The garbage put into the rear box is firstly compressed in the rear box with the dropped middle door as a baffle. After the compression is completed, lift the middle door. The gate pushes the compressed litter block into the front box. In the existing compressed dustbin, steel guide grooves are installed on both sides of the box body and the steel guide rails on both sides of the pull-out middle door cooperate. The middle door is lifted by two sets of hydraulic cylinders. The grooves are matched with steel parts. In order to ensure the stable lifting ...

AI Technical Summary

Problems solved by technology

In the existing compressed dustbin, steel guide grooves are installed on both sides of the box body and the steel guide rails on both sides of the pull-out middle door cooperate. The middle door is lifted by two sets of hydraulic cylinders. The grooves are matched with steel parts. In order to ensure the stable lifting of the middle door, the hydraulic oil intake must be precisely controlled by the computer to ensure that the lifting force of the two groups of oil cylinders on the middle door is equal; if the hydraulic pressure on the left and right sides of the middle door If the lifting force is not equal, it will cause the middle door guide rail and guide groove to be deformed or even damaged

Due to the use of computer control, the complexity of technology and the cost of production and maintenance are increased

In the prior art, the middle door moving up and down in the garbage compressor is guided by a nylon guide groove structure, but this needs to form a groove on the side plate of the box body, and a nylon guide groove is set in the groove, and the groove structure reduces the The strength of the box is not easy to manufacture, install and maintain
