Description

Technical Field

[0001] The utility model relates to the technical field of coal mining crushing devices, in particular to an auxiliary crushing device for coal mining and collection. Background Technique

[0002] Coal mining is to separate valuable coal from underground or the surface and transport it away from the site. Coal deposits occur in layers, with a wide distribution range, large reserves, brittle coal quality, and easy to cut and break. During mining, there are often threats of disasters such as water, fire, and gas. Compared with mining other minerals, coal mining technology has some different characteristics. The mining methods are divided into open-pit mining and underground mining, and usually, mechanical methods are adopted; a small number use hydraulic coal mining; underground gasification of coal is still in the experimental stage. When coal is mined and collected daily, a crushing device is needed to assist in the crushing operation of coal.

[0003] For example, the application number 202310249902.8 discloses an auxiliary crushing device for coal mining and collection, including a roadheader. A moving arm is installed on the roadheader, a machine head is installed on the moving arm, and a drill bit is installed on the machine head. A material receiving device is installed on the bottom side of the machine head, and the material receiving device is used to receive the coal collected by the drill bit. The material receiving device includes a feeding box, the feeding box is movably installed on the bottom side of the machine head, and a material receiving plate is installed on one side of the feeding box close to the drill bit. It should be noted that in the present invention, through the setting of the material receiving device and the feeding and crushing device, the material receiving plate is arranged below the drill bit, so that the coal drilled by the drill bit can be quickly and completely collected, and these coal blocks can be crushed, the coal can be completely collected, and the dust generated by the crushing of the blocky coal during transportation can be avoided. Therefore, the environmental pollution caused by coal scattering can be effectively reduced.

[0004] However, when this auxiliary crushing device for coal mining and collection is in use, although it can better collect and crush coal, it often directly crushes coal through a single crushing roller, and the pre-knocking and crushing effect on larger-volume coal is not high. After the larger coal falls into the crushing device, it will cause incomplete crushing due to the excessive size of the coal, and then it is easy to cause the situation of blockage at the feeding port, thus affecting the crushing efficiency of the crushing device for coal.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an auxiliary crushing device for coal mining and collection is proposed. Content of the Utility Model
