A crushing device

Abstract

The invention discloses a crushing device. A crushing ball is pulled up by utilizing the lever principle, and falls down from a high place after being released, due to the fact that the crushing ballis made from an elastic material, under the action of the gravitational potential energy, the crushing ball can be bounced up on a material placement tray to crush materials, due to the fact that thepotential energy is large at the very beginning, the compression force on the materials is large, the potential energy of the crushing ball is reduced as the materials are compressed into smaller ones, the compression action on the materials is reduced, the size of the compression force of the crushing ball can be changed along with the degree of crushing on the materials, in addition, the crushedmaterials are blown into a collecting device through a fan, the material collecting device is used for guiding air into an air inflation column through an air guide column, an impeller is blown through the introduced air flow to rotate, so that a pulling rope is pulled to enable the crushing ball to obtain potential energy, namely wind power is converted into gravitational potential energy for carrying out crushing, and a driving device does not need to be additionally arranged.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to a crushing device. Background technique [0002] The crushing device is a machine that crushes large-sized fixed raw materials to the required size. The crushing device is composed of coarse crushing, fine crushing, wind conveying and other devices. The external forces applied to the solid during the crushing process include shearing, impact, rolling, and grinding. There are four kinds; the impact is mainly used in the crushing operation; the rolling is mainly used in the high-fineness crushing operation; the crushing devices in the prior art are mostly matched with the screening device; the crushing devices are mostly rotating rollers or crushing balls, Use the driving device to drive the crushing ball to hit and crush the material; or use the driving device to drive the rotating rollers that rotate with each other to grind the material; It is always at the same strength, and ...
