Breaker of swift change tup, screen bar

Technical Field

The utility model relates to the technical field of crushers, in particular to a crusher with hammerheads and screen bars capable of being replaced quickly.

Background

The crusher is a crushing machine which is used in the processing process of metal ores and nonmetallic ores and can crush the mined raw ores into small particles through extrusion, bending and other modes. A hammer crusher is a crushing machine that performs medium and fine crushing operations on materials by using the high-speed impact action of a hammer head. The hammer head is hinged on the rotor rotating at high speed, and the lower part of the machine body is provided with a screen bar to control the discharge granularity. The material fed into the crusher is first crushed by the impact of the hammer head moving at a high speed, and at the same time, kinetic energy is obtained, and the material flies to the crushing plate on the inner wall of the casing at a high speed to be crushed again. The material smaller than the gap of the screen bar is discharged outside the machine, and the material block larger than the gap of the screen bar is impacted and ground by the hammer head on the screen bar again until the material block smaller than the gap of the screen bar is discharged. The hammer crusher has the advantages of large crushing ratio, uniform discharge granularity, less excessive crushed materials, low energy consumption and the like. But the hammerhead and the screen bars are worn out quickly and need to be replaced frequently. When the hammer head and the screen bar of the existing crusher are replaced, the shell needs to be lifted by other equipment, and the existing crusher is limited by the space of the equipment in the use field, is inconvenient to maintain and is difficult to disassemble and assemble.

In the figure: lower box body assembly (1), blanking mouth box body assembly (2), upper cover box body assembly (3), rotor assembly (4), access door assembly (5), hole sealing backplate (6), bolt A (7), ear A (8), bolt B (9), ear B (10), round pin axle (11), connect buckle A (12), connect buckle B (13), tup (14), hammer axle (15), screen bar (16), otic placode (101), pivot board (102), go out pinhole (103).

Detailed Description

The utility model will be further described with reference to the accompanying drawings.

A breaker capable of quickly replacing hammerheads and screening bars comprises a lower box body component 1, a blanking port box body component 2, an upper cover box body component 3, a rotor assembly component 4, a bolt A7, a clamping lug A8, a bolt B9, a clamping lug B10 and a pin shaft 11; a hammer head 14 and a hammer shaft 15 are arranged in the rotor assembly component 4; the lower box body component 1 is internally provided with a screen bar 16; the method is characterized in that: the blanking mouth box body assembly 2 the place ahead be equipped with access door assembly 5, both sides are equipped with out pinhole 103 and hole sealing backplate 6.

The lower box body assembly 1 is provided with an ear plate 101, the access door assembly 5 is provided with a rotating shaft plate 102, the rotating shaft plate 102 is hinged with the ear plate 101 through a pin shaft 11, and the access door assembly 5 can flexibly rotate through the hinge.

The upper part of the access door assembly 5 is provided with a connecting buckle plate A12, the blanking port box body assembly 2 is provided with a connecting buckle plate B13, the connecting buckle plate A12 and the connecting buckle plate B13 are fixedly connected through bolts, and the access door assembly 5 is not easy to fall off through the fixed connection; the fixedly attached bolts are unscrewed before opening the access door assembly 5.
