Description

A kind of pneumatic crusher

Technical field

The utility model relates to a kind of broken, abrasive dust or grinder, particularly relates to a kind of pneumatic broken Machine.

Background technology

At present, a kind of pneumatic crusher can with soft rock of mining within coal mines, exploit, breaking concrete, The occasion of mechanical shock such as open ice.Existing a kind of pneumatic crusher is mainly used on ground, its structure Complicated, volume greatly, the lightest, be not suitable for work high above the ground, underground work.

Utility model content

For the deficiencies in the prior art, the utility model be provide one can clean boot or stopping, Quickly carry out mechanical shock and light and flexible a kind of pneumatic crusher.

In order to solve the problems referred to above, the utility model is achieved through the following technical solutions:

A kind of pneumatic crusher of the present utility model is including the cylinder body with hollow cavity, sliding in described cylinder body Being sealed with hammer body, described hollow cavity is separated into upper plenum and lower cavity by described hammer body, described The lower end of cylinder body connects head, and described head is provided with broken pricker and described broken pricker by pricker card device Bit shank and the lower end pre-contact of hammer body, be provided with at the accent of described lower cavity and slide adaptive with described broken pricker Drill sleeve, the upper end of described cylinder body is sealedly connected with shank body, and described shank body includes being fixed on cylinder ends Handle seat and the elastic pressure handle being arranged on handle seat top, the sidepiece of described handle seat is provided with air inlet pipeline, described handle The bottom of seat is provided with the intake valve group being connected with described air inlet pipeline, and described elastic pressure handle and described air inlet It is disposed with push rod, ball valve and back-moving spring between valve group from top to bottom and realizes pressing or release elasticity Pressure handle to start or stop the operation of intake valve group, described intake valve group by the duct offered on handle seat with Described upper plenum UNICOM, described intake valve group is by the external pipeline of cylinder body and described lower cavity UNICOM and opens It is past to drive hammer body to do that air inlet pipeline is alternately carried out UNICOM with upper plenum and lower cavity by the intake valve group after Dong Multiple motion crushes pricker with continuous percussion.

Further, it is provided with stainless steel filter screen in described air inlet pipeline.

Further, the outside of described handle seat is provided with a pair handle, and described handle is set with glue handle.

Further, described pricker card device is cased with muffler outside the junction of described cylinder body.

Further, security triggers insurance it is provided with between described elastic pressure handle and described handle seat.

Compared with prior art, the beneficial effects of the utility model are: one, this employing pressing or release elasticity Pressure handle also triggers intake valve group by push rod, ball valve, it is achieved clean boot or stopping, compressed air is from entering Air pipe enters intake valve group and guides compressed air alternative expression to enter upper plenum, lower cavity, so that Hammer body moves reciprocatingly and constantly hits broken pricker, reaches the purpose of broken object；The one of utility model Pneumatic crusher is the light-weight handheld formula breaking tool in elongated rod shape, uses more flexible, not by space, The restriction of region, is particularly suitable for work high above the ground, underground work；Two, drill sleeve is arranged on cylinder body, rather than On head, such structure is more stable, durable, survivable, and the connection of cylinder body and head simultaneously is also Without carrying out the complicated programs such as sealing, it is only necessary to bolt is fixed so that dismounts, change accessory more For convenience, practical；Three, the utility model does not use cushioned hammer, by tapping broken pricker, impact between hammer body The strongest, breaking strength is big, it is adaptable to the dismounting of concrete debris and the repairing of building bridge pier.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of a kind of pneumatic crusher of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, make to retouch the most in detail to detailed description of the invention of the present utility model State.Following example are used for illustrating the utility model, but are not limited to scope of the present utility model.
