Mining machinery crushing device based on phase change principle

Abstract

The invention discloses a mining machinery crushing device based on a phase change principle. The mining machinery crushing device comprises a hardness self-adaptive crushing device, an angle dynamic compensation tremor screening mechanism, a crossed double-layer conveying device and a convenient combined moving assembly. The invention belongs to the technical field of mining machinery crushing devices, and particularly relates to a mining machinery crushing device based on a phase change principle. By applying the phase change principle (conversion of two states of the same object), the technical effect that the mining machinery crushing device adjusts the crushing strength in a self-adaptive manner is achieved through the hardness self-adaptive crushing device; the contradictory problem that in the prior art, the crushing force is large (strong crushing force is needed when the size is large) and small (crushing is not carried out when the size is too small) is solved, meanwhile, the lever principle and the gravity effect are reasonably utilized, and the crushing efficiency is greatly improved without intervention of any sensing element; dynamic adjustment of the screening angle is achieved only through the arranged angle dynamic compensation tremor screening mechanism.

Description

technical field [0001] The invention belongs to the technical field of mining mechanical crushing devices, and specifically refers to a mining mechanical crushing device based on the principle of phase change. Background technique [0002] Mining machinery crushing device is also known as mining crusher. At present, commonly used mining crushers include jaw crusher, impact crusher, wind separation crusher, hammer crusher, impact crusher, roller crusher, compound crusher, etc. However, the existing mining mechanical crushing devices mainly have the following problems: [0003] A: The sand and gravel produced by mines are often of different sizes. When the crushing force of the mining mechanical crushing device is too small, the large-grained sand and gravel cannot be fully broken. Lead to inconsistent particle size; [0004] B: Since the existing mining mechanical crushing device cannot adjust its own crushing force according to the size of the sand and gravel, it cannot im...

Problems solved by technology

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a mining machinery crushing device based on the principle of phase change, in view of the fact that the existing mining machinery crushing device cannot adjust its own crushing strength according to the size of the sand and gravel, resulting in sand and gravel discharge In order to solve the problem of unevenness, the invention uses the phase change effect of the non-Newtonian fluid itself to apply the change of the counterattack force of the object, and realizes the technology of self-adaptive adjustment of the counterattack crushing force of the mining mechanical crushing device through the set hardness adaptive crushing device The effect is to solve the problem that the existing technology is difficult to solve the problem that strong crushing force is required when the volume of sand is large, and the volume of sand is too small to no longer be crushed; at the same time, the integrated mining mechanical crushing device cannot adjust the screening angle when the terrain changes In order to realize the effective screening problem, the present invention rationally uses the principle of leverage and gravity, without the intervention of any sensing element and power device, only through the dynamic compensation of the tremor screening mechanism at the set angle, the adjustment of the screening angle is realized. The dynamic adjustment avoids the adverse effect of the geographical location of the integrated mining machinery crushing device on the effectiveness of the screening process. In addition, through the setting of the cross-deck conveying device, the classification and conveying of the crushed sand and gravel are realized, which improves the working efficiency. efficiency
