Abstract

The invention discloses a hydraulic rock digger, which comprises a front impacter shell, a rear impacter shell, an impacter and a rock digging hook, wherein the rock digging hook comprises a rock digging hook body and high-strength rock digging hook teeth; the impacter is arranged in the impacter shells; the impacter shells are connected with the rock digging hook body through a rotating shaft; and the lower part of the rock digging hook body is connected with the high-strength rock digging hook teeth through a positioning pin. The hydraulic rock digger can be used for digging, stripping and crushing hard substances such as rock, concrete and the like. The hydraulic rock digger has two working states: when the impacter does not work, the rock digging hook whole body formed by the rock digging hook body and the high-strength rock digging hook teeth can finish digging and stripping work of the materials; and when the impacter works, the rock digging hook body rotates around the rotating shaft, and the high-strength rock digging hook teeth can also be used for digging and striping while crushing of objects is realized. Thus, the hydraulic rock digger can have the effects of crushing, digging and stripping, and the crushing, digging and stripping can be simultaneously performed.

Description

Hydraulic rock digging device

Technical field

The present invention relates to a kind of engineering equipment, relate in particular to the harder materials such as rock, concrete take off pick, peel off, broken hydraulic rock digging device.

Background technology

Massif, building, concrete etc. are carried out in the process of operation, existing method is to use quartering hammer to carry out fragmentation to object.Because hydraulic hammer is to move from top to bottom, thus hydraulic hammer be can not be used for taking off pick, peel off rock, the object such as concrete.In addition, quartering hammer to impact area less, in the course of the work, its efficiency is lower.

The patent application < < rock splitter for excavator > > that publication No. is CN101914931A provides a kind of rock splitter, and it can be peeled off rock etc., fragmentation.But this device has following shortcoming: one, because it is to utilize piston rod directly to hit lower hook body, the head of piston rod can not get protection, and therefore piston rod easily gets rusty, and is easily subject to mechanical hard injury; Two,, because piston rod does not have stopping means, the downward stroke of piston rod can not be protected effectively, therefore lower hook body around upper hook body rotate in, piston rod is easily got; Three, in whole device, there is no vibration absorber, the hard vibration meeting being therefore subject to when work damages device.

Summary of the invention

Problem to be solved by this invention is to provide a kind of hydraulic rock digging device, and it can be taken off pick to harder materials such as rock, concrete, peels off, fragmentation.

Hydraulic rock digging device of the present invention, it comprises two of front and back impactor housing, impactor, pick rock hook, wherein, pick rock hook comprises pick rock hook body, high strength pick rock briar tooth; Impactor is contained in impactor housing, and impactor housing is connected by rotating shaft with pick rock hook body, and the bottom of pick rock hook body connects high strength pick rock briar tooth by alignment pin; Piston rod, drill steel are from top to bottom housed in impactor, and both contact; When impactor is worked, piston rod moves up and down, and constantly hits drill steel; In the top cavity of pick rock hook body, be provided with high strength cemented carbide, under its drill steel in impactor; When drill steel moves up and down, constantly shock high strength carbide alloy, makes to dig rock hook body and rotates around the axis.

Hydraulic rock digging device of the present invention has two kinds of duties: when impactor is not worked, the pick rock hook entirety that pick rock hook body and high strength pick rock briar tooth forms can complete takes off pick, stripping operation to material; When impactor is worked, pick rock hook body rotates around the axis, and high strength pick rock briar tooth, when realizing object fragmentation, also can be taken off pick, peel off.Therefore hydraulic rock digging device of the present invention not only can play broken but also can play the effect of taking off pick, peeling off, and broken with take off pick, peel off and can carry out simultaneously.

The specific embodiment

From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of hydraulic rock digging device of the present invention, it comprises two of front and back impactor housing 1, impactor 2, pick rock hook, wherein, pick rock hook comprises pick rock hook body 3, high strength pick rock briar tooth 4; Impactor 2 is contained in impactor housing 1, and impactor housing 1 is connected by rotating shaft 5 with pick rock hook body 3, and the bottom of pick rock hook body 3 connects high strength pick rock briar tooth 4 by alignment pin 16; Piston rod 8, drill steel 9 are from top to bottom housed in impactor 2, and both contact; When impactor 2 is worked, piston rod 8 moves up and down, and constantly hits drill steel 9; In the top cavity of pick rock hook body 3, be provided with high strength cemented carbide 10, under its drill steel 9 in impactor 2; When drill steel 9 moves up and down, constantly shock high strength carbide alloy 10, makes to dig rock hook body 3 and 5 rotates around the shaft.

When impactor 2 is not worked, the pick rock hook entirety that pick rock hook body 3 and high strength pick rock briar tooth 4 forms can complete takes off pick, stripping operation to material.

When impactor 2 is worked, the piston rod 8 in impactor 2 moves up and down, and constantly hits drill steel 9; Drill steel 9 moves up and down, and constantly shock high strength carbide alloy 10 makes to dig rock hook body 3 and 5 rotates around the shaft, drives high strength pick rock briar tooth 4 to realize the taking off pick, peel off of object, fragmentation.Whole motion while working due to impactor 2 is to transmit successively by piston rod 8, drill steel 9, carbide alloy 10, so can effectively protect piston rod 8 and cylinder body thereof.

As a modification of the present invention mode, it also comprises the stopping means that limits pick rock hook body 3 strokes; Stopping means is comprised of alignment pin 6 and positioning bolt 7, and positioning bolt 7 contacts with the limiting plate in impactor housing 1.This stopping means pick rock hook body 3 has been carried out spacing in, also make the drill steel 9 in impactor 2 can not drop out.

As another improved procedure of the present invention, because the present invention is subject to larger vibration when working, come to harm, so the present invention is provided with vibration absorber, can effectively alleviate vibration, thereby protect better hydraulic rock digging device.Vibration absorber, because the difference of hydraulic rock digging device concrete form is different, is specifically described as follows:
