Screen strip rotation hammer type crusher

Abstract

The invention discloses a screen strip rotation hammer type crusher. The screen strip rotation hammer type crusher comprises a machine shell, a heavy hammer device, a screen strip device, a first drive device and a second drive device. The screen strip device comprises a screen strip assembly. The screen strip assembly is of an annular or U-shaped structure formed by multiple screen strips arranged in parallel. The screen strip assembly wraps the outer portion of the heavy hammer device. The first drive device and the screen strip assembly are connected to drive the screen strip assembly to rotate. In the screen strip rotation hammer type crusher, when sticky materials with the high water content are encountered and the materials are beaten to screen strips, some materials can be bonded to the surfaces of the screen strips, due to rotation of the screen strips, the materials bonded to the screen strips can disengage during screen strip moving or can be beaten away by materials when the angles of the screen strips change, finally the screen strips rotate to extrusion cavities and are extruded and ground through hammer heads to be cleaned thoroughly, and therefore material accumulation can be effectively avoided, and the blockage situation is eradicated.

Description

technical field [0001] The invention relates to the technical field of object crushing, in particular to a sieve bar rotary hammer crusher. Background technique [0002] During the crushing process of coal gangue, shale, tailings, clay and other materials, the materials are quickly hit to the impact plate after contact with the crushing hammer, and return to the secondary crushing with the materials and the crushing hammer after impact. The crushing hammer and the sieve plate are extruded until the qualified material is discharged through the sieve plate, and the crushing process is completed; however, when encountering viscous materials with high moisture content, the materials will hit the impact plate, and some will stick to it and accumulate thicker, resulting in crushing chamber, The sieve plate is blocked, the crushing effect is greatly reduced, the motor load is increased, and the crushing hammer head is seriously worn; when the machine is parked to clean up the mater...

Problems solved by technology

[0002] During the crushing process of coal gangue, shale, tailings, clay and other materials, the materials are quickly hit to the impact plate after contact with the crushing hammer, and return to the secondary crushing with the materials and the crushing hammer after impact. The crushing hammer and the sieve plate are extruded until the qualified material is discharged through the sieve plate, and the crushing process is completed; however, when encountering viscous materials with high moisture content, the materials will hit the impact plate, and some will stick to it and accumulate thicker, resulting in crushing chamber, The sieve plate is blocked, the crushing effect is greatly reduced, the motor load is increased, and the crushing hammer head is severely worn; when the car is parked to clean up the material, it is particularly firm and difficult to clean, which is time-consuming and laborious.
