Abstract
The utility model relates to a crushing device of a hydraulic crusher, and belongs to the field of engineering mechanical device. The crushing device comprises a front shell and a drill rod, wherein the drill rod is sequentially sheathed with a front end lining and a round lining; the front shell is fixedly connected with fixing grooves in both sides of the drill rod and the drill rod through two drill rod pins; two retaining pins are respectively connected with the front shell and the two drill rod pins in a vertical interspersing manner; two front end sleeve retaining pins are arranged below the drill rod pin; and the two front end sleeve retaining pins are respectively and fixedly connected with grooves in both sides of the front end lining. By adopting the device, the front shell and the drill rod are fixed by using the drill rod pin, so that the connection between the front shell and the drill rod is reliable and is not easy to be damaged. The crushing device has the characteristics of high working efficiency and low noise, and excavators cannot be damaged.
Description
Technical field
The utility model relates to engineering machinery device field, is 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 by piston movement, make drill rod produce impact force action on rock, rely on impact force to make rock rupture.But that the shortcoming of this breaker is efficient is low, noise large, impact force reaction meeting to excavator produce damage, and can not the larger rock of fragmentation volume.
Summary of the invention
The purpose of this utility model provides a kind of breaker of hydraulic burster, and it is by adopting the drill steel pin to fix between fore shell and the drill steel, and is so that fore shell reliably is connected with drill steel, not fragile.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises fore shell and drill steel, described drill steel is socketed front end lining, circular lining successively, described fore shell is fixedly connected with described drill steel with the holddown groove of drill steel both sides by two drill steel pins, two retaining pins are connected with fore shell, two vertical interting of drill steel pin respectively, the below of described drill steel pin is provided with two front end sleeve retaining pins, and described two front end sleeve retaining pins are fixedly connected with the groove of described front end lining both sides respectively.
As improvement, the bottom of described drill steel is taper.
As improvement, the middle part of described fore shell is provided with the tank filler sleeve with the consistent lubricant joint.
As improvement, described retaining pin is provided with the first rubber stopper on the top of described fore shell outside.
As improvement, be provided with the second rubber stopper on the top of the outside described front end sleeve retaining pin of described fore shell.
As improvement, be provided with snap ring between described the second rubber stopper and the front end sleeve retaining pin.
The utility model is by adopting the drill steel pin to fix between fore shell and the drill steel, not fragile so that fore shell reliably is connected with drill steel, have high efficiency, noise low, can be to driving the characteristics such as excavator generation damage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of drill steel in the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, this specific embodiment is by the following technical solutions: it comprises fore shell 1 and drill steel 2, described drill steel 2 is socketed front end lining 11, circular lining 10 successively, described fore shell 1 is fixedly connected with described drill steel 2 with the holddown groove 2-1 of drill steel 2 both sides by two drill steel pins 4, two retaining pins 5 are connected with fore shell 1, two 4 vertical interting of drill steel pin respectively, the below of described drill steel pin 4 is provided with two front end sleeve retaining pins 7, and described two front end sleeve retaining pins 7 are fixedly connected with the groove 11-1 of described front end lining 11 both sides respectively.
The bottom of described drill steel 2 is taper.
The middle part of described fore shell 1 is provided with the tank filler sleeve 1-1 with consistent lubricant joint 3, is convenient to refuel by tank filler sleeve 1-1.
Described retaining pin 5 is provided with the first rubber stopper 6 on the top of described fore shell 1 outside, can prevent effectively that dust, impurity etc. from entering in the fore shell 1.
The top of described fore shell 1 outside described front end sleeve retaining pin 7 is provided with the second rubber stopper 8.
Be provided with snap ring 9 between described the second rubber stopper 8 and the front end sleeve retaining pin 7, be convenient to better to fix between rubber stopper and the retaining pin.
This specific embodiment is by adopting the drill steel pin to fix between fore shell and the drill steel, not fragile so that fore shell reliably is connected with drill steel, have high efficiency, noise low, can be to driving the characteristics such as excavator generation damage.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
