Abstract

The utility model discloses an impact crusher. The impact crusher comprises a frame, a feed hopper arranged on the frame and a rotor assembly arranged in the frame, wherein the rotor assembly comprises a plate hammer, a liner plate, a rotor, a rotor shaft, a flywheel and a belt wheel; and the plate hammer is fixedly arranged on the liner plate through bolts, the liner plate is fixedly connected with the rotor, the rotor is connected with the rotor shaft through a locating pin and a flat key, the flywheel and the belt wheel are respectively arranged on the two ends of the rotor shaft, and the joints of the flywheel and the rotor shaft as well as the belt wheel and the rotor shaft are both provided with bearing glands. The impact crusher disclosed by the utility model has the advantages that a plurality of rows of single hammer heads are combined into the plate hammer, so that the contact area of a material and the plate hammer is increased, the counterattack crushing capacity of the equipment is improved, and the loss of the quick-wear parts is reduced.

Description

A kind of impact crusher

Technical field

The utility model relates to the mining equipment technical field, more particularly, relates in particular to a kind of impact crusher.

Background technology

To be generally the tup that utilizes High Rotation Speed carry out high speed impact to the material of crusher chamber with impact crusher, make material generation impact grinding, and make material piece high-speed punching after impact to counterpunch board, material is on counterpunch board again after impact grinding, hit the district and repeat above-mentioned shattering process from the counterpunch board tup that rebounds again, simultaneously in material coming and going between tup and counterpunch board, also there is each other the effect of collision impact fragmentation.The impact crusher that uses now, it is the single tup of the some rows of assembling on rotor, because the differences such as broken material is big or small, composition, material, cause each tup degree of wear uneven, change very inconvenient, and also having larger gap between same row's tup, material easily brings damage to rotor and tup from the side.

The utility model content

The purpose of this utility model is to provide a kind of impact crusher for above-mentioned the deficiencies in the prior art, increases the contact area of material and bar, improves the impact crushing ability, reduces the loss to consumable accessory.

For achieving the above object, impact crusher provided by the utility model, comprise frame, be arranged on the feed hopper on frame and be arranged on the interior rotor assembly of frame, described rotor assembly comprises bar, liner plate, rotor, rotating shaft, flywheel and belt wheel, bar is mounted by means of bolts on liner plate, liner plate is fixedly connected with rotor, rotor is connected with rotating shaft with flat key by alignment pin, flywheel and belt wheel are arranged on respectively the two ends of rotating shaft, in the junction of flywheel and belt wheel and rotating shaft, bearing gland are installed all.

The utility model is merged into bar with the single tup of some rows, reasonably utilized the confined space of frame inside, increased the contact area of material and bar, given full play to the effect of whole bar, improved the impact crushing ability of equipment, reduced the loss to consumable accessory, and crushing efficiency has been reached maximum.
