Mechanical material crushing device

Abstract

The invention discloses a mechanical material crushing device. The mechanical material crushing device disclosed by the invention is reasonable and simple in structure, low in production cost, convenient to install, and capable of crushing materials with a large volume; the materials enter from a charge port; a drive motor drives a cam to rotate through a belt; the cam contacts with a contact plate; a movable rod realizes reciprocating motion under the action of a spring; a fixed crushing plate and a movable crushing plate crush large materials; the materials continue to be crushed through a crushing gear after being crushed; the materials enter into the crushing chamber; small materials fall into a grinding chamber through a sieve screen, and the large materials continue to be crushed bya crushing rod; the materials are grinded by a grinding roll in the grinding chamber; and in order to ensure the crushing effect, the materials are further poured into a second crushing chamber, and continue to be crushed through a long crushing rod and a short crushing rod. Through the abovementioned technical scheme, crushing for the materials with the large volume is realized.

Description

Technical field: [0001] The invention relates to the technical field of crushing, in particular to a mechanical material crushing device. Background technique: [0002] The crusher is suitable for crushing medium-hard materials in industrial sectors such as cement, chemical industry, electric power, metallurgy, building materials, refractory materials, such as limestone, slag, coke, coal and other materials. Roller crushers are generally divided into pair-roller and single-toothed-roller. It is mainly composed of toothed rollers, roller support bearings, pressing and adjusting devices, and driving devices. [0003] Existing crushers generally work with a toothed roller and a toothed plate, and the crushing cavity is small, so it is not suitable for crushing materials with excessive volume. Invention content: [0004] The object of the present invention is to provide a mechanical material crushing device in order to solve the above problems, which solves the problem that ...
