Detailed Description

The applicant describes embodiments of the present application with reference to the drawings.

The upper cover 2 mainly comprises a square hole B21, a rotating shaft B22, a rotating hole B23, a lifting hook 24 and a damping groove B25, the square hole B21 is used for installing the lining plate 8, the lifting hook 24 is used for lifting the crusher or the upper cover, and the lifting hook 24 is mainly used for installing or maintaining the crusher.

In general welt mounting hole, all be the circular port, quad slit first 12 and quad slit second 21 of this application are the quad slit, it is corresponding, screw hole 81 on the welt 8 is the quad slit, the screw rod is square screw, easy to assemble, thus, even welt 8 damages, quad slit first 12 and quad slit second 21 of fuselage 1 and upper cover 2 can not damage yet, thereby conveniently unscrew the nut, after the machine installation, spout one deck paint or add the butter on the screw rod, then utilize the adhesive tape to tie up the screw rod, during the maintenance, tear the adhesive tape, unscrew the nut, support the screw rod to in the breaker, because most breakers have the mounting bracket, thus, under the condition of not opening the breaker, welt 8 will fall out the breaker, convenient dismantlement.

The reinforcing ribs A5 are positioned below the grid bars, and the reinforcing ribs A5 can still support the grid bars 4 after the grid bars 4 are worn, so that the service life of the grid bars 4 is prolonged.

It should be noted that, the early part crusher is a shock pad manufactured by using waste automobile tires or thin copper sheets, but both of the two shock pads have poor effects, the shock pad manufactured by using waste tires can cause the situation that nuts are locked on the machine body 1 and the upper cover 2, so that the nuts are easy to loosen, once the nuts are loosened, a large amount of internal dust is sprayed to a bearing position, the bearing is damaged quickly, the thin copper sheets are too thin and difficult to effectively absorb shock, the thin copper sheets are easy to tear in a shock process, and the copper sheets are expensive, so the thin copper sheet shock pad is difficult to effectively popularize, and through tests, the aluminum shock pad with the thickness of more than 3mm has a good effect.

The main shaft 9 of the general crusher is provided with the dustproof ring, but the dustproof ring is generally an annular ring, the conical dustproof ring 91 is adopted in the crusher, and dust such as stone dust can fly towards the inner wall of the crusher along the conical dustproof ring without being blocked after reaching the conical dustproof ring, so that the dust is prevented from rebounding back after reaching the dustproof ring, and the dust in the crusher is serious.

The general crusher body is formed by welding or integral casting, the precision is very limited no matter welding or integral casting, in addition, the welded body is difficult to improve the precision through machining, the high manganese steel is also formed by casting, the fitting degree of a lining plate and the body is limited after assembly, and the performance of the lining plate is negatively influenced.
