High Frequency Hammer Dual Motor Crushing Device

Abstract

The invention discloses a double-motor crushing device of a high frequency crushing hammer. The double-motor crushing device comprises a vibration generator, a four connecting rod mechanism and a shaking knife row, wherein the vibration generator comprises a shell, a first driving shaft arranged in the shell, a first driven shaft which is mutually meshed with the first driving shaft through gears, a second driving shaft, a second driven shaft which is mutually meshed with the second driving shaft through gears as well as a bridge crossing shaft arranged between the first driving shaft and the second driving shaft; the bridge crossing shaft is mutually meshed with the first driving shaft and the second driving shaft gears, the first driving shaft, the first driven shaft, the second driving shaft and the second driven shaft are all provided with eccentric wheels and gears. The double-motor crushing device disclosed by the invention has the advantages that as two groups of actuating shafts are adopted and matched with two actuating motors, the crushing force of the crushing hammer actuated by the two actuating motors is large relative to that of the crushing hammer actuated by the single motor, the crushing accuracy is high, the noises are small, and the crushing capacity is strong, thus the operation time of the crushing hammer is prolonged, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to a high-frequency breaker, in particular to a double-motor breaker for the high-frequency breaker. Background technique [0002] Breaking hammer is a physical crushing equipment that integrates mechanical hydraulics, digital signals, and digital monitoring. The teeth of the breaking hammer can generate impact force on objects under the action of a vibration exciter, and then achieve crushing. A general breaking hammer is driven by a hydraulic motor to rotate the eccentric wheel, thereby generating a centrifugal force F, whose vertical component Fsinwt is a periodically changing disturbance force, which causes the shaft to generate radially forced vibration pressure, which is called the excitation force, and then by the excitation force The box of the vibrator transmits the vibration to the cutter teeth for crushing. [0003] The existing vibrator only has a single motor for driving. When encountering some difficult-to-break obj...

AI Technical Summary

Problems solved by technology

[0003] The existing exciter is only driven by a single motor. When it encounters some difficult-to-break objects, it will make it difficult for the breaker to break and cause fatigue or even damage. It will also reduce the vibration energy in the break direction, greatly reducing the breakage effectiveness
