Abstract
The invention discloses a breaking device of a hydraulic breaker, which relates to the field of engineering mechanical devices. The breaking device comprises a front case and a drill rod, wherein the drill rod is sequentially in sleeve connection with a front-end bushing and a circular bushing, the front case is fixedly connected with the drill rod by two drill rod pins and hold-down grooves on both sides of the drill rod, two stop pins are respectively in vertically alternate connection with the front case and the two drill rod pins, two front-end bushing stop pins are arranged below the drill rod pins, and the two front-end bushing stop pins are respectively fixedly connected with grooves on both sides of the front-end bushing. According to the invention, the front case and the drill rod are fastened by using the drill rod pins, so that the front case and the drill rod are reliably connected and uneasy to damage; and the breaking device has the characteristics of high operating efficiency, low noise, and no damage produced on drive excavators, and the like.
Description
Technical field
The present invention relates to engineering machinery device field, be specifically related to a kind of breaker of hydraulic burster.
Background technology
The hydraulic breaking hammer power resources of using in the engineering at present are in excavator, loader or pumping plant; Drive operating principle full hydraulic, liquid gas association type etc. are arranged; All be to promote drill rod, make drill rod produce impact force action on rock, rely on impact force to make rock rupture through piston motion.But that the shortcoming of this breaker is an efficient is low, noise big, impact force reaction meeting to excavator produce damage, and can not the bigger rock of fragmentation volume.
Summary of the invention
The breaker that the purpose of this invention is to provide a kind of hydraulic burster, it is fixed through adopting the drill steel pin between fore shell and the drill steel, makes fore shell reliably be connected with drill steel, and is not fragile.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: it comprises fore shell and drill steel; Said drill steel is socket front end lining, circular lining successively; Said fore shell is fixedly connected with said drill steel with the holddown groove of drill steel both sides through two drill steel pins; Two stopping pins are connected with fore shell, two vertical interting of drill steel pin respectively, and the below of said drill steel pin is provided with two front end sleeve stopping pins, and said two front end sleeve stopping pins are fixedly connected with the groove of said front end lining both sides respectively.
As improvement, the bottom of said drill steel is taper.
As improvement, the middle part of said fore shell is provided with the tank filler sleeve that has the consistent lubricant joint.
As improvement, said stopping pin is provided with first rubber stopper on the outside top of said fore shell.
As improvement, be provided with second rubber stopper on the top of the outside said front end sleeve stopping pin of said fore shell.
As improvement, be provided with snap ring between said second rubber stopper and the front end sleeve stopping pin.
The present invention fixes through adopting the drill steel pin between fore shell and the drill steel, makes fore shell reliably be connected with drill steel, and is not fragile, have high efficiency, noise low, can be to driving characteristics such as excavator generation damage.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the sketch map of drill steel among the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2; This specific embodiment adopts following technical scheme: it comprises fore shell 1 and drill steel 2; Said drill steel 2 is socket front end lining 11, circular lining 10 successively; Said fore shell 1 is fixedly connected with said drill steel 2 with the holddown groove 2-1 of drill steel 2 both sides through two drill steel pins 4; Two stopping pins 5 are connected with fore shell 1, two 4 vertical interting of drill steel pin respectively, and the below of said drill steel pin 4 is provided with two front end sleeve stopping pins 7, and said two front end sleeve stopping pins 7 are fixedly connected with the groove 11-1 of said front end lining 11 both sides respectively.
The bottom of said drill steel 2 is taper.
The middle part of said fore shell 1 is provided with the tank filler sleeve 1-1 that has consistent lubricant joint 3, is convenient to refuel through tank filler sleeve 1-1.
Said stopping pin 5 is provided with first rubber stopper 6 on said fore shell 1 outside top, can prevent effectively that dust, impurity etc. from getting in the fore shell 1.
The top of said fore shell 1 outside said front end sleeve stopping pin 7 is provided with second rubber stopper 8.
Be provided with snap ring 9 between said second rubber stopper 8 and the front end sleeve stopping pin 7, be convenient to better to fix between rubber stopper and the stopping pin.
This specific embodiment is fixed through adopting the drill steel pin between fore shell and the drill steel, makes fore shell reliably be connected with drill steel, and is not fragile, have high efficiency, noise low, can be to driving characteristics such as excavator generation damage.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Other modifications that those of ordinary skills make technical scheme of the present invention perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of technical scheme of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
