Description
Technical field
The utility model is specifically related to the good pneumatic pick head of a kind of smashing capability.
Background technology
Pneumatic pick is power with compressed air, utilizes the hand-held construction equipment of percussion crushing hard objects.Be a kind of hand tool, therefore claimed structure is compact, takes with light.Pneumatic pick is made up of valve actuating mechanism, beater mechanism and pick rod etc.Beater mechanism is a heavy wall cylinder, inside has a jump bit can be reciprocating along cylinder inner wall.The afterbody of pick rod inserts the front end of cylinder, and distribution clack box is equipped with in cylinder rear end.
Many longitudinal pores are had in the surrounding of cylinder wall, the spring of compression plunger valve and connect gas circuit, these pore one end wildcard air valves, push handle sleeve, the other end passes into cylinder, the length of each pore configures according to the movement needs of jump bit, so that air inlet or exhaust in turn, plunger valve is in the normally off cutting off gas circuit under helical spring effect.Jump bit is moved back and forth regularly in cylinder.When jump bit travels forward, tup hits bit shank; When jump bit moves backward, the gas confinement in cylinder, in distribution clack box, forms flexible buffer bed course, and the gas confinement in cylinder, in distribution clack box, impacts forward after distribution again again.Tup hits bit shank; When jump bit moves backward, the starting drive of pneumatic pick is positioned at handle jacket.Between blast pipe and distributing valve, have a plunger valve to control gas circuit, plunger valve is in the normally off cutting off gas circuit under helical spring effect.During pneumatic pick operation, make pick rod withstand construction surface, the other end passes into cylinder, push handle sleeve, the spring of compression plunger valve and connect gas circuit, and have many longitudinal pores in the surrounding of cylinder wall, distributing valve is automatic distributing immediately, and distribution clack box is equipped with in cylinder rear end.Jump bit is constantly moved back and forth, hits bit shank, broken construction body.Pneumatic pick is a kind of hand tool, and pneumatic pick is made up of valve actuating mechanism, beater mechanism and pick rod etc.Therefore claimed structure is compact, takes with light.In engineering construction, the excavation for hard soil often needs to loosen with special engineering machinery, could be transported after soil breaking.But it is poor for some (when being restricted by surrounding structure effect on building or working space) operating modes, special engineering machinery is due to the place of volume ratio more very much not constructability, excavation for hard soil is just very difficult, often needs the artificial pickax that uses to cut the earth, wastes time and energy.And some pneumatic pick header structures for hard soil are fairly simple, effect is bad, inefficiency, needs a pocket long working when excavating hard soil, and it is comparatively large to dig out hard soil build, is unfavorable for very much process.
