Squeezing-adjustable crushing device

Abstract

The invention provides a squeezing-adjustable crushing device and relates to the field of crushing devices. The squeezing-adjustable crushing device comprises a machine shell, crushing rollers and a squeezing mechanism, wherein the crushing rollers are rotatably mounted in the machine shell; the squeezing mechanism comprises squeezing rollers and a squeezing driving structure; the squeezing rollers are arranged on the feeding side of the crushing rollers in parallel at intervals; and the squeezing driving structure is in transmission connection with the squeezing rollers. The device also comprises a squeezing adjusting bracket movably installed on the machine shell, the squeezing rollers are rotationally installed on the squeezing adjusting bracket, and an adjustable squeezing roller gap is formed between the squeezing rollers. A material enters the machine shell and is extruded and righted through the squeezing roller gap of the squeezing rollers; after the material is subjected to preliminary extrusion, the material enters the subsequent crushing rollers to be crushed; and the extruded material is easier to enter a crushing roller gap between the crushing rollers, and the material biting effect of the crushing rollers is effectively improved. The squeezing rollers rotate opposite to each other to achieve extrusion in the squeezing process, the continuity of squeezing is ensured, and the crushing effect of a whole machine is better.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to crushing equipment with adjustable pressing material. Background technique [0002] In order to improve the crushing efficiency of materials, a pressing structure is usually installed on the upper part of the cutter roller of the crushing equipment, and the extrusion effect of the pressing structure on the material is used to make the cutter roller quickly bite the material to reduce the time of no-load operation. [0003] For example, the Chinese invention patent application with the application publication number CN109939777A and the application publication date of 2019.06.28 discloses a double-roller crushing device, and specifically discloses that the double-shaft crushing device includes a box body and a pair of rollers arranged in the box body. barrel, a pressing device arranged at the upper end of the roller and a number of crushing devices at the lower end; the u...
