Further, the width of the leading section of described tup is greater than the diameter of flange hole.

Further, an end face of described iron block is fixedly connected with blind plate by connection pipe, and connection pipe is connected with admission port, on another end face of iron block, is evenly provided with several pores.

Further, to be diameter of the housing 2/3rds identical as for diameter of the housing for the diameter of described iron block.

Further, described exhausr port is obliquely installed.

Further, described blind plate and flange are fixedly connected with housing by bolt.

Further, on described induction tract, be provided with electromagnetic valve.

The present invention, by existing bunker wall vibration pneumatic hammer is improved, has following beneficial effect: 1, simplified airflow pipeline, made apparatus structure simpler; 2, adopt cast tube as housing, thereby solved the sealing problem of housing surrounding; 3, by bolt, blind plate and flange are connected with housing, are convenient to dismounting and maintenance; 4, exhausr port is obliquely installed, and has reduced to greatest extent impurity and has entered housing, thereby reduced the wearing and tearing of piston, the service life of extension device; 5, on iron block end face, several pores are evenly set, make air-flow more even, the motion of piston is more stable; 6, the piston that is arranged so that of iron block and magnet can reset in time, realizes crank motion; 7, by the width of the leading section of tup being greater than to the diameter of flange hole, thereby have an accident while having avoided tup to depart from spring.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment 1;

Fig. 2 is the structural representation of the iron block of embodiment 2.

The specific embodiment

The present invention is by adopting cast tube as the housing of pneumatic hammer, on the leading section of housing, admission port is set, exhausr port is set in rear sidewall, enclosure interior arranges piston, and with spring, piston is connected with tup, thereby piston can, under compressed-air actuated effect, be promoted tup and do rapping campaign.

Below in conjunction with accompanying drawing, embodiments of the invention are illustrated:

Embodiment 1, novel bunker wall vibration pneumatic hammer as shown in Figure 1, comprise housing 2, housing 2 adopts cast tube, thereby solve the sealing problem of housing surrounding, simultaneously easy to use, the leading section of housing 2 is bolted to connection blind plate 1, thereby easy disassembly, maintenance, for guaranteeing sealing, between blind plate 1 and housing 2, packing seal is set, prevent that pressurized air from leaking from blind plate 1 and the junction of housing 2, blind plate 1 is provided with admission port 4, blind plate 1 arranged outside air inlet pipe 8, air inlet pipe 8 is connected with admission port 4, the inner side of blind plate 1 is fixedly installed iron block 11, the diameter of iron block 11 is 2/3rds of housing 2 diameter of sections, thereby guarantee enough adsorption affinitys, iron block 11 connects admission port 4 by connection pipe 10, iron block 11 center is arranged at the pore 12 that connection pipe 10 is communicated with, the inside of described housing 2 is provided with piston 3, the corresponding iron block of leading section of piston 3 arranges magnet, by iron block 11 and magnet are set, piston 3 can be resetted in time, guarantee the past renaturation of rapping, piston 3 is fitted with the inwall of housing 2, and air tight, housing 2 rearward end are bolted flange 6, on flange 6, be provided with flange hole, bolt connection side dismounting and maintenance, the rearward end of piston 3 connects the leading section of tup 7 by spring 5, the width of the leading section of tup 7 is greater than the diameter of the flange hole on flange 6, thereby avoided having an accident when tup 7 departs from spring, the rearward end of tup 7 is stretched out housing 2 by the flange hole of flange 6, on the sidewall at the rear portion of housing 2, be provided with exhausr port 9, exhausr port 9 is obliquely installed, thereby reduce to greatest extent impurity and enter housing 2 inside, piston 3 is caused to wearing and tearing.

Embodiment 2, several pores 12 are evenly set on the end face of iron block 11 as shown in Figure 2, the arranging of pore 12 guaranteed piston stressed evenly, the pressurized air entering by admission port 4, after the several pores on iron block 11, air-flow is more even, thereby the thrust that piston is produced is also more even, thereby makes the motion of tup 7 more stable.

Other content of the present embodiment is with embodiment 1.

Under the effect of iron block and magnet, piston 3 is inhaled mutually with iron block, pressurized air enters housing 2 inside by admission port 4, by loose gas plate, make air-flow more even, promote piston 3 motions, under the motion of piston 3, gas is discharged by exhausr port 9, piston 3 promotes tup 7 and does rapping action, piston 3, under the antagonistic force of rapping and the effect of magnetic force, is got back to initial position, thereby carries out reciprocal rapping.

Novel bunker wall vibration pneumatic hammer of the present invention, simple in structure, easy to maintenance, reduced equipment cost, reduce to greatest extent impurity and enter enclosure interior, thereby the wearing and tearing of piston have been reduced, in the service life of extension device, the loose device of air of setting makes air inlet more even, and the motion of piston is more stable.
