Overloading protection structure for garbage crushing device

Abstract

The invention discloses an overloading protection structure for a garbage crushing device, which comprises a machine body, a drive motor mounted on the top wall of the machine body, a garbage inlet arranged at the upper end of the side wall of the machine body, a garbage outlet arranged on the bottom wall of the machine body, and a crushing assembly positioned in the machine body. The overloading protection structure for the garbage crushing device is characterized in that the crushing assembly consists of a rotation shaft which is rotatably arranged between the bottom wall and the top wall of the machine body and connected with the drive motor, a crushing shaft rotatably installed on the rotation shaft, and crushing blades installed on the crushing shaft. When the garbage crushing device is overloaded, force resulting from the overload enables a transverse slider to contract inwards by overcoming the extruding force of the liquid, and after the transverse slider is separated from arc grooves inside the crushing shaft, a motor shaft rotates normally and the crushing shaft is incapable of rotating, thus preventing the motor from burnout due to overloading.

Description

[0001] This application is a divisional application of a Chinese invention patent application whose application date is October 18, 2016, and the application number is 201610904833X, and the invention name is a garbage crushing device. technical field [0002] The invention relates to the technical field of garbage disposal, in particular to an overload protection structure of a garbage crushing device. Background technique [0003] At present, domestic garbage and construction waste need to be recycled uniformly. The recycled garbage needs to be shredded before further processing of the garbage, such as making fertilizers, producing building materials, and landfill disposal. During the garbage shredding process, motors are often used The crushing knife crushes the garbage, but the garbage is often accompanied by objects that are difficult to break, which will greatly increase the crushing resistance, and the greater resistance will often cause the motor to burn due to overlo...
