Wear-proof hammer crusher

Abstract

The invention discloses a wear-proof hammer crusher, and relates to a crushing device. The wear-proof hammer crusher comprises a machine shell, a transmission shaft supported in the machine shell and a plurality of hammer bodies fixedly arranged on the transmission shaft. A feeding opening is formed in the top of the machine shell, a U-shaped sieving plate is arranged in the machine shell, sieving holes are formed in the bottom of the sieving plate, and the multiple hammer bodies are defined by the sieving plate; a first connecting rod is arranged on the inner wall of the machine shell, one end of the sieving plate is hinged to the first connecting rod, and a second connecting rod is hinged to the other end of the sieving plate and runs through the machine shell outwards; an installing frame is also arranged on the outer wall of the machine shell, a driving motor is installed on the installing frame, an eccentric wheel is fixedly arranged on an output shaft of the driving motor, and the other end of the second connecting rod is hinged to the eccentric wheel; the inner surface of the sieving plate is coated with a wear-proof layer. By means of the wear-proof hammer crusher, crushed materials can be rapidly sieved to be discharged through the sieving plate, and it is prevented that the materials are stacked on the sieving plate.

Description

technical field [0001] The invention relates to a crushing device, in particular to a wear-resistant hammer crusher. Background technique [0002] The wear-resistant hammer crusher mainly relies on impact energy to complete the operation of crushing materials. When the wear-resistant hammer crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly, and the high-speed rotating hammer impacts, shears and tears the material, causing the material to be broken. The material rushes from the high-speed rotating hammer head to the baffle plate and sieve bar in the frame, and the material larger than the sieve hole size is retained on the sieve plate and continues to be hit and ground by the hammer until it is crushed to the required discharge particle size and finally passes through the sieve plate Drain out of machine. However, the existing sieve plates have poor wear resistance. Under long-term use, coal mines not...

Problems solved by technology

However, the existing sieve plates have poor wear resistance. Under long-term use, coal mines not only easily wear the inner surface of the sieve plate, but also easily cause the sieve plate to break, which affects the working efficiency of the equipment.
