Abstract

The invention discloses a novel coal crushing device. The novel coal crushing device comprises a base. A first crushing box and a second crushing box are fixed at the upper end of the base. A first crushing cavity is formed in the first crushing box, and a second crushing cavity is formed in the second crushing box. A material conveying plate is arranged in the first crushing cavity. A first extending-and-contracting device is arranged at the lower end of the material conveying plate. The two ends of the first extending-and-contracting device are correspondingly and fixedly connected with thebottom end side wall in the first crushing cavity and the lower end side wall of the material conveying plate. A buffering device is arranged at the lower end of the material conveying plate. A feeding opening communicated with the first crushing cavity is formed in the upper end of the first crushing box. Two rotating shafts are arranged in the first crushing cavity. The two rotating shafts are correspondingly and fixedly sleeved with crushing rollers. One ends of the two rotating shafts are correspondingly and rotationally connected with fixing blocks. The novel coal crushing device performssecondary crushing on coal, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal crushing equipment, in particular to a novel coal crushing device. Background technique [0002] Coal is coal. It is a kind of black or brown-black solid combustible mineral substance transformed by plant residues undergoing different degrees of decomposition. It needs to be crushed in the process of coal production. [0003] However, the existing coal crushing device performs primary crushing, and the crushing efficiency is not high. Contents of the invention [0004] 1. Technical problems to be solved [0005] The purpose of the present invention is to solve the problem that the existing coal crushing device performs primary crushing and the crushing efficiency is not high, and proposes a new coal crushing device. [0006] 2. Technical solution [0007] In order to achieve the above object, the present invention adopts the following technical solutions: [0008] A new type of coal crushing d...
