Hammering type crusher

Abstract

The invention relates to the technical field of stone crushing, and discloses a hammering type crusher. When a telescopic machine performs retraction movement, an adjusting plate and a stroke plate move towards the two sides, a wedge block can be pulled away from the stroke plate, and therefore a contact inclined block moves in the direction of the outer side of a screening and filtering cavity under the action of a reset spring, the contact inclined block can drive sieve plates to synchronously move while moving, and at the moment, the distance between the sieve plates can be gradually increased; and if the telescopic machine performs stretching movement, the adjusting plate and the stroke plate can get close to the middle, at the moment, the wedge block can be inserted into the stroke plate, and therefore the wedge block pushes the contact inclined block to move in the axis direction of a stroke rod and towards the circle center of the screening and filtering cavity, and at the moment, the distance between the sieve plates can be gradually decreased. According to the structure and the adjusting mode, a screening and filtering device does not need to be disassembled, and meanwhile, shutdown is not needed; and compared with a traditional hammering type crusher which needs to disassemble and reinstall the sieve plates, the mode has the advantages that the operation difficulty is reduced, and the crushing efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of stone crushing, in particular to a hammer crusher. Background technique [0002] Hammer crusher is a common type of crusher in sand and gravel production. Its principle is to drive the driving pulley to rotate through the power system, so as to drive the rotor to rotate and drive the hammer head fixed on the rotor to rotate. The hammer head is driven by centrifugal force. Under the action of the crusher, the stones in the crushing chamber are crushed, and a certain number of screening rods are installed inside the crushing chamber. During the installation process, the screening rods will leave a certain gap between them, so that the screening rods can withstand the stone materials. While hitting and crushing it, it can also play a role of screening. This kind of hammer crusher is small in size, convenient in transportation, low in use cost, and has a good crushing effect on stone materials, so it can be u...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing hammer crushers proposed in the background technology, the present invention provides a hammer crusher, which has the advantage of adjusting the screening distance without stopping the machine, and solves the problem of traditional hammer crushers. The problem of cumbersome and complicated disassembly and assembly work is required when adjusting the sieve plate gap
