Rotor of reversible crusher

Abstract

The invention discloses a rotor of a reversible crusher. The rotor comprises a main shaft (11), a hammer disk (33) with pin holes (22), hammer handles (44), hammer heads (55) and connecting pins. The rotor is characterized in that the rotor also comprises a driven disk (66); and the driven disk (66) is in an idling sleeve connection relationship with the periphery of the hammer disk (33) and is connected to the hammer handles (44). The hammer handles (44) are connected into an integral body by the driven disk (66), and when one of the hammer handles (44) swings, the swinging hammer handle drives other hammer handles to swing at the same amplitude and thus in hammer head working, energy is not lost easily, hammer head motion rigidity is improved without increasing of hammer head quality and a hammer head speed, and fragmentation effects are improved.

Description

technical field [0001] The invention relates to a reversible crusher in the field of mining machinery, in particular to a rotor body of the reversible crusher. Background technique [0002] The rotor body of the existing reversible crusher includes a main shaft 1, a hammer plate 2, a hammer handle 3, a hammer head 4 and various connecting pins, wherein, there is a boss 8 in the middle of the hammer handle 3, and one end thereof is connected to the hammer head 4 through a hammer head pin 5 , the other end is connected to the hammer plate 2 through the hammer handle pin 6, and can swing around the hammer handle pin 6 to a certain extent under the limitation of the boss 8. The working principle is: driven by the motor, the rotor body rotates at a high speed, and the hammer handle and The hammer heads are radially arranged under the action of centrifugal force, and the material 7 is crushed at high speed. When a hammer head hits the material, the speed decreases due to energy lo...

AI Technical Summary

Problems solved by technology

[0004] (1) Since only part of the hammer head swings during work, it is very easy to cause the center of gravity of the rotor to shift, resulting in equipment vibration

[0005] (2) Since the crushing effect is directly related to the energy of the hammer head, the energy of a single hammer head is limited

According to the kinetic energy formula, there are two ways to increase the energy of the hammer head: one method is to increase the mass of the hammer head, and the other is to increase the speed of the hammer head, but increasing the mass of the hammer head will increase the total mass of the rotor body, making it difficult for the motor to start And increase the no-load load, resulting in increased energy consumption; increasing the speed of the hammer head will lead to increased vibration of the equipment and increased wear of the hammer head, shortening the service life of the hammer head
