Description

A kind of trigger of new pusher leg drill and its attachment structure
Technical field
This utility model is related to a kind of trigger of new pusher leg drill and its attachment structure, main to use
In colliery, metallurgy, railway, traffic, water power, capital construction and national defence cubic meter of stone construction project.
Background technology
The operation principle of pusher leg drill is：With air compressor machine output compressed air as power, gases at high pressure Jing shank bodies Pass sequentially through manipulation valve and import air chamber, the passage in Jing ratchets hole, then piston is controlled by rock drill distributing valve and make reciprocal at a high speed Motion.During stroke, piston impact drill steel and bore bit dig crushed rocks；During backhaul, piston driving drill steel and bore bit turn round certain angle Degree, continuous Ground shock waves, revolution make bore bit dig out circular blasthole on rock.
The trigger of pusher leg drill is arranged on the left upper of shank body afterbody, and the Main Function of trigger is by the tune in shank body The reversal valve pressure installed in pressure valve endoporus, compressed air advance to the cavity of resorption of air leg cylinder, and the compressed air in epicoele is just Can be discharged by compression.Because being provided with spring, when trigger is unclamped, reversal valve recovers the reversal valve other end under spring force It is in situ.At this moment compressed air is just truncated into the passage of air leg lower chamber of air cylinder, while exhaust passage is opened.
As shown in figure 1, existing have problems with use with trigger：
1st, made using engineering plastics, it is not wear-resisting with reversal valve contact site；
2nd, trigger poor rigidity, reversal valve pressure are not in place；
3rd, handgrip part is short, and operator pulls arduously；
The problems referred to above can all have influence on the size that air leg lower chamber of air cylinder enters the amount of compressed air, and then affect what air leg stretched Speed.Need Jing often to change trigger, many inconvenience are brought to user, affect being normally carried out for production.The work of operator simultaneously Intensity is big.
Raising is improved to used trigger, has the meaning of reality, while can also lift pusher leg drill work Stability and product quality.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of laborsaving, durable and operation spirit for the problems referred to above It is living, reversal valve transposition can be made flexibly, time saving and energy saving, wearability is good, long service life, and commutation is accurate
In place, rock drill is reduced because air leg shrinks the new pusher leg drill of the fault rate of dumb appearance Trigger；
This utility model additionally provides a kind of attachment structure of above-mentioned trigger.
This utility model is employed the following technical solutions：A kind of trigger of new pusher leg drill, including handle, Handle has end and root, and the thickness of root is more than the thickness of end.
The following is further improvement of the utility model：
The distance between root and end are b, and b is 62-65mm.
Further improve：
Connecting portion is connected with the handle, and the angle between handle and connecting portion is a, and a is 80-82 °.
Further improve：
Connecting portion is connected with root, arc-shaped transition between connecting portion and root.
Further improve：
One end on the connecting portion away from root is connected with compressed part.
Further improve：
Pin-and-hole is offered on the connecting portion.
A kind of attachment structure of the trigger of novel airleg rock drill, it is including left handle, trigger, left above to be offered groove, Trigger is rotatably connected in groove by elastic cylindrical pin, and elastic cylindrical pin runs through groove and pin-and-hole.
This utility model has following technique effect using above-mentioned technical proposal：
1st, the wearability of trigger is improve, long service life greatly reduces the cost that user uses；
2nd, the rigidity of trigger is improve, trigger can accurately press position when reversal valve is pressed, and substantially increase the spirit of air leg contraction Activity, reduces the fault rate that rock drill is used；
3rd, novel trigger handgrip part is lengthened, and rapid operation reduces the labor intensity of workman.
This utility model is further illustrated with example below in conjunction with the accompanying drawings.

Specific embodiment
Embodiment, as shown in Fig. 2 a kind of trigger of new pusher leg drill, including handle A, handle A has end Portion 11 and root 10, the thickness of root 10 are more than the thickness of end 11, and the distance between root 10 and end 11 are b, and b is 62- 65mm。
Connecting portion 9 being connected with the handle A, the angle between handle A and connecting portion 9 is a, being a, a is 80-82 °.
Connecting portion 9 is connected with root 10, arc-shaped transition between connecting portion 9 and root 10.
One end on the connecting portion 9 away from root 10 is connected with compressed part C.
Pin-and-hole B is offered on the connecting portion 9.
As shown in figure 3, a kind of attachment structure of the trigger of novel airleg rock drill, including trigger 2, left 1, spring 7th, elastic ring 6, shank body 8, reversal valve 5, pressure regulator valve 4, elastic cylindrical pin 3.
Trigger 2 is mounted in the left groove coordinated with which 1, is fixed on left on 1 by elastic cylindrical pin 3, then this is combined It is mounted in shank body 8；Reversal valve 5 is coordinated with pressure regulator valve 4, and reversal valve nose end is equipped with spring, and another section with the bullet being mounted in pressure regulator valve 4 Property ring fix, then pressure regulator valve 4 and 5 molectron of reversal valve are put in shank body 8.
Reversal valve 5 can be such that reversal valve 5 moves forward and backward in the inner chamber of pressure regulator valve 4 loaded on inside pressure regulator valve 4 using trigger, Change airintake direction by connecting different air flues.The important function of trigger 2 promotes reversal valve 5 to commutate.
In the left groove D 1, trigger 2 and the left connection 1 are through left 1 by elastic cylindrical pin 3 to trigger 2 The pin-and-hole B of the first pin-and-hole F and trigger 2 is connected as a single entity, and trigger 2 can be rotated around elastic cylindrical pin 3, then is mounted in shank body 8 by left 1 On.
Spring 7 is mounted in 5 spring eye H of reversal valve, and elastic ring 6 is mounted in the elastic annular distance G of pressure regulator valve 4, is changed for limiting It is offside in the presence of spring 7 to valve 5.
In pusher leg drill work, when 2 handle location A of trigger is pulled with handss, compressed part C just presses reversal valve inward 5, spring 7 is just compressed, and realizes commutation；When loose one's grip handle A when, in the presence of spring 7, reversal valve 5 returns to original position.
