Abstract
The utility model discloses a counter-attack board device for an impact crusher. The counter-attack board device comprises a rotor, a counter-attack board, a casing and a flow guiding plate. The rotor, the counter-attack board and the flow guiding plate are fixed on the casing. The counter-attack board device is characterized by comprising a first counter-attack board, a second counter-attack board and a third counter-attack board. The first counter-attack board, the second counter-attack board and the third counter-attack board are spliced to form a rectangle. The first counter-attack board and the second counter-attack board are in a shape of a right angular trapezoid, the third counter-attack board is in a shape of a parallelogram. Fixing holes are arranged on the first counter-attack board, the second counter-attack board and the third counter-attack board, and the first counter-attack board, the second counter-attack board and the third counter-attack board penetrate through the fixing holes on the first counter-attack board, the second counter-attack board and the third counter-attack board to be fixed on the casing through screws. Compared with the prior art, the counter-attack board device has the advantages that the structure is simple, the counter-attack plate is divided into three plates, if one plate is damaged, users only need to replace the damaged plate, and replacing cost is reduced.
Description
Technical field
The utility model relates to a kind of impact crusher counterpunch board device that is used for.
Background technology
Impact crusher is a kind of high energy low consumption impact cutting with international most advanced level, and its performance plays irreplaceable effect in the carefully broken equipment of various ores, be the most effective at present, practical and reliable rubble machine.The impact crusher that uses at present, material receives a series of pulverizations such as counterpunch board counterattack after getting into body, and qualified material is discharged.Disintegrating machine in use, counterpunch board is vulnerable to big impact and causes fracture, needs during replacing to change the monoblock counterpunch board, use cost is high.
The utility model content
The utility model technical problem to be solved is, overcomes the defective that prior art exists, and a kind of reasonable in design is provided, and can avoid changing the monoblock counterpunch board, practice thrift replacement cost in impact crusher counterpunch board device.
The utility model addresses the above problem the technical scheme that is adopted: this is used for impact crusher counterpunch board device; Comprise rotor, counterpunch board, housing, deflector; Rotor, counterpunch board and deflector all are fixed on the housing; It is characterized in that: said counterpunch board comprises first counterpunch board, second counterpunch board and the 3rd counterpunch board; Described first counterpunch board, second counterpunch board and the 3rd counterpunch board piece together rectangle, and wherein first counterpunch board and second counterpunch board are right-angled trapezium, and the 3rd counterpunch board is a parallelogram; All have fixing hole on first counterpunch board, second counterpunch board and the 3rd counterpunch board, first counterpunch board, second counterpunch board and the 3rd counterpunch board are fixed on the housing through the fixing hole that screw passes on first counterpunch board, second counterpunch board and the 3rd counterpunch board.
Acute angle in the said parallelogram of the utility model is 80 degree.
The size of said first counterpunch board of the utility model, second counterpunch board is all identical with shape.
The utility model compared with prior art has the following advantages: simple in structure, counterpunch board is split into 3, if any a damage, only needs to change to damage that piece, has reduced replacement cost.
