Abstract

The utility model relates to a crusher, which comprises, from the top to the bottom, a handle body, a cylinder and a machine head, wherein, an operating valve set arranged in the lower portion of the middle gas cavity of the handle body is different from the prior models and adopts a specific design that a valve plate is disposed in a valve plate movement cavity between an upper valve chest and a lower valve chest. In operation, the gas from a gas source is alternately dispensed to an upper space and a lower space of an inner hammer block in the cylinder under the action of the valve plate and each air hole respectively provided on the upper and the lower valve chests, and the compressed gas drives the hammer block to make reciprocated movement and to knock the tail portion of a stem through a punching head, thereby achieving the crusher function. By adopting the unique and innovative valve set design, the utility model has simpler structure, long service life, and wide generalization and application space, can prevent damage of the valve set and can save gas consumption by 30-50 percent compared with the prior models under the same impact energy.

The specific embodiment

Below in conjunction with accompanying drawing the utility model being done one describes in detail.

The utility model relates to a kind of disintegrating machine, comprise handle body 2 from top to bottom, cylinder 12 and head 15, in the described head 15 drill steel is housed, be provided with hammer body 22 in the described cylinder 12 in order to impact drill steel, described cylinder 12 upper ends join with the operating valve group of being located in the air cavity bottom, handle body 2 middle part, described handle body 2 also has and its air cavity top, middle part admission line that is connected and the intake valve of being located in the admission line 26, it is characterized in that: described operating valve group comprises, following

valve cabinet

6,9 and be positioned at plane valve block 8 in the middle of the two valve cabinets, described valve cabinet central through hole down communicates with cylinder 12, described valve cabinet 6 bottoms of going up are provided with the valve block movable air cavity coaxial with last valve cabinet, and be provided with by the upper surface and penetrate into startup air admission hole 29 in the movable air cavity of valve block, the inlet channel 30 of the movable air cavity of described valve block through turning valve cabinet lower surface upwards and the penetrating that is positioned at valve cabinet central through hole periphery down be valve cabinet and with to be located at the passage 31 that air admission hole that cylinder wall leads to the cylinder bottom links to each other continuous down, also be provided with on the described upward valve cabinet 6 and be positioned at the peripheral descending air admission hole 32 of the hammer body that penetrates the valve cabinet that makes progress in week of the movable air cavity of valve block, described valve cabinet 9 upper surfaces down are provided with the annular groove 33 that docks with the descending air admission hole of hammer body 32 lower ends, described annular groove 33 is between following valve cabinet central through hole and passage 31, and its inner ring surface is long-pending less than plane valve block 8 areas.

Gas comes downwards to the cylinder bottom for convenience, and above-mentioned valve cabinet 9 lower surfaces down are provided with the annular groove 34 that docks with passage 31 lower ends, and dock with annular groove 34 the air admission hole upper end on the described cylinder 12.
