Double-wheel self-crushing wear-resistant device of hammer crusher

Abstract

The invention provides a double-wheel self-crushing wear-resistant device of a hammer crusher, and relates to the field of hammer crushers. The double-wheel self-crushing wear-resistant device comprises two supporting plates, wherein the two supporting plates are rigid plates with inclined upper surfaces, side plates are fixed in the middles of the inclined edges of the upper surfaces of the two supporting plates, a top plate is fixed at the upper ends of the two side plates, a front side plate is fixed at the front ends of the side plates and the top plate, a rear side plate is fixed at the rear ends of the side plates and the top plate, and feeding grooves are formed in the front side surface of the front side plate in a left-right symmetry mode. According to the double-wheel self-crushing wear-resistant device, materials are automatically driven upwards from the lower end to enter the position below the top plate through a belt which rotates upwards, so that feeding is facilitated; the materials are used for secondary crushing, so that impact and abrasion to a machine body are reduced, the service life is prolonged, and the crushing effect is good; a transverse rod is driven to rotate through the belt, so that the crushed materials are pushed to move, and blockage is prevented; and two push plates are close to or far away from each other by rotating on the supporting plates through threaded connection of threaded rods in first sliding holes, so that the particle size can be adjusted at will, and adjustment is facilitated.

Description

technical field [0001] The invention relates to the field of hammer crushers, in particular to a double-wheel self-breaking wear-resistant device of a hammer crusher. Background technique [0002] In cement, chemical industry, electric power, metallurgy and other industrial sectors, materials with medium hardness are crushed, such as limestone, slag, coke, coal and other materials that need to be crushed and finely crushed, and hammer crushers are often used for crushing. Conventional hammer crushers They are all fed from the top. Workers put large pieces of material into the crusher from the top. The labor intensity is high, the energy consumption is high, and the risk is high. In addition, the conventional hammer crusher has only one runner, and the hammer head on the runner The material is hit at high speed, the material flies in the casing at high speed, and hits the impact plate for secondary crushing. The impact plate needs to withstand the high-speed impact of the mat...

Problems solved by technology

[0002]In cement, chemical industry, electric power, metallurgy and other industrial sectors, it is used to crush materials with medium hardness, such as limestone, slag, coke, coal and other materials that need medium and fine crushing. Hammer crushers are often used for crushing. Conventional hammer crushers are fed from the upper end. Workers put large pieces of material from the upper end of the crusher, which is labor-intensive, consumes a lot of energy, and is dangerous. The hammer crusher has only one runner. The hammer on the runner hits the material at high speed. The material flies in the casing at high speed and hits the impact plate for secondary crushing. The impact plate needs to withstand the high-speed impact of the material and requires mechanical strength. It is relatively high, and it is easy to wear after a period of use, and the crushing cost is high. In a conventional hammer crusher, the material in the conventional hammer crusher is easy to block the screen when it is discharged after being crushed, and the screen needs to be replaced when it is crushed or finely crushed. Trouble, unable to automatically adjust the granularity
