Description
Technical field
The utility model relates to a kind of hydraulic shock accessory, particularly relates to a kind of excavator hydraulic shock accessory, belongs to large hydraulic machinery field.
Background technology
Existing excavator hydraulic shock accessory has two kinds, and one is that hydraulic system pressure acts directly on and piston promotes reciprocating motion of the pistons and form percussion action and formed with drill steel and collide, and impact energy is applied in object to be broken by drill steel.Another is agent structure is quadric chain, and the alternating stresses that eccentric annular flow mechanism drives impact bar reciprocating action to form reciprocating impact under the interlock effect of air spring makes object to be broken broken.
The first technical scheme is applicable to the higher broken occasion of formation hardness, but its fragmentation only has impact energy to cause its crushing efficiency lower.
The second technical scheme mainly uses vibrations and alternating stresses to carry out fragmentation, and the quality that quadric chain can not participate in crushing operation directly occupies larger part.Be limited to the carry ability of excavator, the shaking force that this broken accessory unit mass produces is lower, is only applicable to being applied in formation hardness lower than the occasion of 8 degree.
Utility model content
The deficiency that the utility model exists for above-mentioned existing technologies, provides a kind of excavator hydraulic shock accessory.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of excavator hydraulic shock accessory, its composition comprises: frame and several flexible connection mechanisms and impact body, described frame is connected with hydraulic crawler excavator, described flexible connection mechanism one end is fixedly connected with described impact body by bolt, the other end is fixedly connected with described frame by bolt, described impact body both sides are provided with some to eccentric wheel, gear-box is provided with in described impact body, even number gear is furnished with in described gear-box, each described gear driven described eccentric wheel, accumulator is provided with at described impact body top, described accumulator one end is fixedly connected with described impact body by bolt, one end is fixedly connected with described frame by bolt in addition.
Described excavator hydraulic shock accessory, the working portion of described impact body can be cataclasitlc structure and rammer flat structure for being applicable to different operating mode.
Described excavator hydraulic shock accessory, the eccentric wheel direction of rotation described in often pair is contrary, and rotating speed is identical, rotates the centrifugal force produced identical.
The beneficial effects of the utility model are: crushing efficiency of the present utility model comparatively hydraulic breaking hammer improves into four times, can the rock of broken hardness more than 8 degree, 2-3 times of the high-frequency vibration hammer of four-bar linkage structure under the heavy condition of the identical machine of impact force, can a tractor serves several purposes be accomplished simultaneously, both can do the accessory use that quartering hammer also can do vibrations rammer and other types.

Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of excavator hydraulic shock accessory, its composition comprises: frame 2 and several flexible connection mechanisms 5 and impact body 6, described frame 2 is connected with hydraulic crawler excavator 1, described flexible connection mechanism 5 one end is fixedly connected with described impact body 6 by bolt, the other end is fixedly connected with described frame 2 by bolt, described impact body 6 both sides are provided with some to eccentric wheel 4, gear-box 8 is provided with in described impact body 6, even number gear 7 is furnished with in described gear-box 8, each described gear 7 drives a described eccentric wheel 4, accumulator 3 is provided with at described impact body 6 top, described accumulator 3 one end is fixedly connected with described impact body 6 by bolt, one end is fixedly connected with described frame 2 by bolt in addition, if when the energy storage effect of described flexible connection mechanism 5 well can reach requirement, also can install at the accumulator 3 at described impact body 6 top.
Described excavator hydraulic shock accessory, the working portion of described impact body can be cataclasitlc structure 9 and rammer flat structure 10 for being applicable to different operating mode.
Described excavator hydraulic shock accessory, the eccentric wheel direction of rotation described in often pair is contrary, and rotating speed is identical, rotates the centrifugal force produced identical.
Described excavator hydraulic shock accessory, hydraulic pressure accessory is connected in the frame that is connected with hydraulic crawler excavator by deformable flexible connection mechanism, often pair of eccentric wheel direction of rotation is contrary, rotating speed is identical, the centrifugal force that the rotation of the two produces is identical, formed at the centrifugal force perpendicular to eccentric wheel axis of rotation line direction and make a concerted effort to promote impact body and to move up and down formation working effect, when impact body moves upward, impact body drives elastic deformation bindiny mechanism to produce deformation energy accumulation, accumulator compression energy accumulation, when impact body moves downward, elastic deformation bindiny mechanism and accumulator release energy, the combination that centrifugal force suffered by impact body is made a concerted effort and two accumulating mechanisms release energy drives impact body to form fragmentation, compacting or other working effects.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
