Abstract

The utility model discloses an impact breaker which comprises a case body, a rotating shaft positioned inside the case body and a rotating body driven by the rotating shaft and provided with a plate hammer, wherein water chamber bearing supports are arranged on the two sides of the rotating shaft, spacer sleeves are mounted on the rotating shaft which has a key groove, rotary plates which are arranged among the spacer sleeves are connected through keys, the rotary plates are connected with the plate hammer through a protective plate, a distance-adjustable chute plate is arranged on the lower side of a feed port, a hanging rod which is arranged at the top of an upper case body is connected with an inner arc-shaped impact plate which is arranged inside the case body, and an inner straight impact plate which is arranged on one side of the case body is connected with a pull rod which is arranged at the lower part of the case body. The impact breaker adopts the design of clamping structure of the plate hammer, so as to reduce the rotating force applied by the plate hammer to the rotating body, reduce the force on the bearing and ensure good effect of dissipating the frictional heat of the bearing. The hammer tool has a scientific and reasonable design, is wear-resistant, does not need to be changed frequently, and is not blocked by large-sized particles during the crushing and the feeding processes to prevent shutdown of the rotating body. The crushing cavity of the case body is fully utilized to ensure the material-hammering effects of the hammer tool.

Description

Impact breaker

Technical field

The utility model relates to the field of cracking machine in mine, the building material machinery, particularly a kind of mine impact breaker.

Background technology

Existing impact breaker is owing to work long hours, and bearing friction heat radiation is bad, turns from great, and bearing is produced exertin, and the oil in the bearing block solidifies to make and produces big resistance when starting in the winter time, causes bearing fragile; The hammer project organization that drives of turning is unreasonable, and need easy to wear are often changed, and during broken charging, material particles is big slightly just to block hammer easily, and making turns stops suddenly, causes motor to damage.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the impact breaker that a kind of energy consumption is low relatively, wear-resistant, crushing efficiency is high is provided.

The utility model provides following technical scheme for achieving the above object: a kind of impact breaker, comprise casing, be positioned at the rotating shaft of casing and the rotary body that bar is housed that drives by rotating shaft, bearing is equipped with on the rotating shaft both sides, drive places the axle head of a side rotating shaft to be in transmission connection with it, it is characterized in that the rotating shaft both sides are equipped with the water cavity bearing block, have in the rotating shaft of keyway spacer is housed, the rotating disk between the spacer connects with key, and rotating disk is connected with bar by backplate; The roll adjustment sliding plate is installed below charging aperture, and the suspension rod at upper box top is connected with interior camber counterpunch board in the case, and the straight type counterpunch board that is positioned at casing one side is connected with the pull bar of lower box.

Described water cavity bearing block constitutes whole watt box by FE Tiler and a watt seat, and the bearing end in watt box is provided with the location and inserts lid, and communicating with oilhole on watt box has oil groove outside bearing, has oilhole on the FE Tiler and leads to the water injection hole of bearing block water cavity.

Described rotating disk is connected with connecting plate by bearing pin, links to each other with bar with jackscrew with the backplate that connecting plate joins.

Be with spring on the described pull bar, both ends of the spring is equipped with adjustable rear spring seat and front spring seat respectively, and rear spring seat is connected with side box plate behind the lower box.

The design of the utility model bar interface arrangment has weakened the rotary gravity of bar to rotary body, has also alleviated the power that is applied on the bearing simultaneously, bearing friction good heat dissipation effect; The hammer project organization is scientific and reasonable, wear-resistantly need not frequent replacing, during broken charging, has both made material particles greatly also can not block hammer and has made the parking of turning; The casing crusher chamber can make full use of, and has guaranteed the hammer effect of hammer to material, uses this crusher machine efficient height, few easy workout part, and operating maintenance is convenient.
