Background

The impact crusher is named according to the working principle, namely, the impact crusher crushes materials by utilizing the impact crushing principle, is crusher equipment which is thinner than a jaw crusher, is mainly used for medium-fine crushing operation in a stone production line, and enables a rotor part to rotate at a high speed through belt transmission when the impact crusher works. When the materials enter the plate hammer action area, the materials are collided and crushed with the plate hammer on the rotor, then the materials are thrown to the impact frame to be crushed again, the uncrushed materials rebound to the plate hammer action area from the impact frame to be crushed continuously, the process is repeated, the materials are repeatedly crushed through the first impact cavity, the second impact cavity and the third impact cavity from large to small until the materials are crushed to the required granularity, and the materials are discharged from the discharge hole. In the use process, vulnerable parts such as a counterattack frame and a plate hammer of the main machine are easily abraded, so that the discharge granularity is gradually increased, and the discharge granularity is required to be controlled by adjusting the gap of the discharge opening. The conventional mode is that a discharge hole gap is manually controlled and mechanically adjusted, and the size of the discharge hole is manually measured after adjustment, so that the problems of manpower waste and low efficiency exist; and the impact frame structure of the existing impact crusher does not have the overload protection function, and the impact frame structure directly controls tripping and shutdown through the current of the motor during overload, thereby influencing normal production.

The labels in the figure are: 1. the balance control device comprises a lower frame body, 2, a dial, 3, a counterattack frame, 4, a pointer, 5, a split pin, 6, a gasket, 7, a hydraulic cylinder, 8, a hydraulic cylinder support, 9, a cylinder body pin shaft, 10, a piston rod pin shaft, 11, a hydraulic station, 12 and a balance control device.

Detailed Description

Referring to the drawings, the specific embodiments are as follows:

a discharge port hydraulic control system of an impact crusher is used for controlling an impact frame 3 to rotate on a lower frame body 1 so as to adjust the size of a discharge port, a dial 2 is installed on the outer side face of one side of the lower frame body 1, a pointer 4 capable of synchronously rotating along with the impact frame 3 is installed on a main shaft of the impact frame 3, and the size of the discharge port is indicated through the matching of the pointer 4 and the dial 2. In this embodiment, because calibrated scale 2 is located the lateral surface of lower support body 1, consequently personnel can follow the outside direct observation of impact crusher and expect that the mouth size, and no longer need the manual work to observe the measurement in the crushing chamber.
