Multi-stage rock-soil crushing device with recovery function

Abstract

The invention relates to the technical field of rock-soil crushing, in particular to a multi-stage rock-soil crushing device with a recovery function, and aims to solve the technical problems that part of existing rock-soil crushing devices are low in crushing efficiency; part of existing crushing devices are difficult to recover rock soil which is not completely crushed; and in the using process of part of existing crushing devices, filter screens are prone to being blocked, and the filtering effect is poor. In order to solve the technical problems, the invention provides the multi-stage rock-soil crushing device with the recovery function, which comprises a machine shell. A motor is fixedly connected to the front end of the outer wall of the machine shell. The multi-stage rock-soil crushing device with the recovery function is composed of a crushing mechanism, a recovery mechanism and a filtering mechanism. Rock soil is thrown to the surface of an impact plate through cooperation of the centrifugal force generated in the rotating process of a rotating sleeve and compression springs, then the rock soil rebounds to the surface of a crushing plate and is crushed through cooperation of crushing rods, compression springs drive the crushing plate to pop out the rock soil after being pressed, and repeated crushing is conducted in the process, so that the overall crushing efficiency of the equipment is improved.

Description

technical field [0001] The invention relates to the field of rock and soil crushing, in particular to a multi-stage rock and soil crushing device with recovery function. Background technique [0002] Crusher is the most common equipment in quarrying sites. It can be divided into cone crusher, jaw crusher, centrifugal crusher and impact crusher by crushing methods, among which impact crusher is the most common. A crusher, which has a multi-stage crushing effect; [0003] The existing patent (notification number: CN111111848A) discloses an impact crusher, including a main body, a feeding mechanism, and a crushing mechanism. The upper side of one end of the main body is fixed with a feeding port, and the inner side of the main body is provided with an impact plate. . In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been resolved: 1. During use, the crushing device can only crush the rock and s...
