Hydraulic impact crusher

Abstract

The invention relates to an excavator matching device, in particular to a vibration box of a hydraulic impact crusher. The vibration box mainly comprises a vibration box body, a vibration box connecting shaft, a damping air bag, a driving shaft, driven shafts, eccentric shafts and a hydraulic pipe, an upper driven shaft, the driving shaft and a lower driven shaft are arranged in the vibration box body, the driving shaft is located in the middle, the eccentric shafts and gears are installed on the driving shaft and the driven shafts, the driving shaft gears correspondingly mesh with the upper driven shaft and the lower driven shaft, a damping air bag is arranged at top end of the vibration box, the tail end of the vibration box can be connected with a drill rod, and the vibration box body is hinged to a lifting frame of the hydraulic impact crusher through the vibration box connecting shaft. The vibration box of the hydraulic impact crusher has the beneficial effects of being simple in structure, high in durability, low in maintenance difficulty, low in production cost, large in crushing force, high in precision, low in noise and high in crushing capacity.

Description

technical field [0001] The invention relates to an excavator matching device, in particular to a hydraulic impact breaker based on the application of the excavator. Background technique [0002] In the prior art, hydraulic impact breaker (hydraulic impact breaker) is an important working tool of hydraulic excavator, which is installed on backhoe loader for crushing operation. When the piston strokes, it hits the drill rod at high speed, and the drill rod breaks solids such as ore and concrete. The power source is the pressure oil provided by the pump station of the excavator or loader. Chinese patent CN 203695168 U discloses a high-frequency breaker, including installation, a vibrator, a four-bar linkage mechanism and a vibrating knife row. The first driven shaft meshing with each other, the second driving shaft, the second driven shaft meshing with the second driving shaft through gears, and the bridge shaft installed between the first driving shaft and the second driving ...

Chinese patent CN 203695168 U discloses a high-frequency breaker, including installation, a vibrator, a four-bar linkage mechanism and a vibrating knife row. The first driven shaft meshing with each other, the second driving shaft, the second driven shaft meshing with the second driving shaft through gears, and the bridge shaft installed between the first driving shaft and the second driving shaft; One drive shaft, one end of the second drive shaft are respectively equipped with a first drive motor and a second drive motor; the central axes of the first drive shaft and the second drive shaft are on the same vertical plane; the first drive shaft and the first driven The shaft, the second driving shaft and the second driven shaft are located on the same horizontal plane. Two sets of drive shafts are used, and two drive motors are used to overcome the weak crushing force, low crushing precision, high noise and crushing capacity in the prior art. weak defect

However, this high-frequency breaker has the disadvantages of complex structure, difficult maintenance, high production cost, and short service life, making it difficult to popularize
