Abstract
The invention discloses a kind of four bar drill holes to be crushed cement block assembly, it is by drill bit thread, drill bit, drillstock, pull rod, strut, expansion board, crushing shell, fixed pin, sliding rail and stay rod pin composition, drill bit described in it is fixedly connected with drillstock one end, drill bit thread is welded on drill bit outer surface, there are two pairs of symmetrical fixed pins up and down on drillstock, strut, fixed pin and sliding rail are sequentially connected, two stay rod pins be fixedly connected on two above and below the pull rod of fixed pin corresponding position at, and stay rod pin is inside sliding rail, two strut other sides and expansion board are flexibly connected, expansion board is crushing shell on one side, crushing shell is welded on the outside of expansion board.Beneficial effect utilizes the characteristic of four rod structures, generate in raw expansionary force, rotate chopping ground from side, expanded aperture, saved manpower, to prevent people easy to catch cold, the fishing that makes to make a hole in the ice becomes very easily thing.
Description
Technical field
The present invention relates to a kind of crushing devices, and in particular to be that a kind of four bar drill holes are crushed cement block assembly.
Background technique
At this stage, cement is widely used, since over time, cement will appear some column situations such as corrosion, therefore need
Original cement is crushed.Under normal circumstances, the broken of cement is all to be knocked open using tup and iron pick, but this method is not
Only not only laborious but also inefficiency.
Summary of the invention
Present invention deficiency according to existing for above-mentioned technology provides a kind of broken cement block assembly in four bar drill holes.In order to reach
Above-mentioned purpose, the technical solution adopted by the present invention is that: a kind of four bar drill holes are crushed cement block assembly, be by drill bit thread, drill bit,
Drillstock, pull rod, strut, expansion board, crushing shell, fixed pin, sliding rail and stay rod pin composition, described in drill bit be fixedly connected with drillstock
One end, drill bit thread are welded on drill bit outer surface, have on drillstock up and down two pairs of symmetrical fixed pins, strut, fixed pin and sliding rail according to
Secondary connection, two stay rod pins be fixedly connected on two above and below the pull rod of fixed pin corresponding position at, and stay rod pin is inside sliding rail,
Two strut other sides and expansion board are flexibly connected, and expansion board is crushing shell on one side, and expansion board welds crushing shell on outside.
The beneficial effects of the present invention are: generating interior raw expansionary force using the characteristic of four rod structures, chopping ground is rotated from side
Aperture has been expanded in face, saves manpower, so that crushing cement be made to become very easily thing.
Detailed description of the invention
Fig. 1, which is that the present invention is whole, to be intended to；
1- drill bit thread；2- drill bit；3- drillstock；4- pull rod；5- strut；6- expansion board；7- crushing shell；8- fixed pin；9- sliding rail；
10- stay rod pin.
Specific embodiment
Specific description is done to the present invention with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the present invention is a kind of broken cement block assembly in four bar drill holes, it is by drill bit thread 1, drill bit 2, drillstock
3, pull rod 4, strut 5, expansion board 6, crushing shell 7, fixed pin 8, sliding rail 9 and stay rod pin 10 form, described in drill bit 2 fixed connect
3 one end of drillstock is connect, drill bit thread 1 is welded on 2 outer surface of drill bit, there are upper and lower two pairs of symmetrical fixed pins 8 on drillstock 3, and strut 5 is consolidated
Rationed marketing 8 and sliding rail 9 are sequentially connected, two stay rod pins 10 be fixedly connected on two above and below the pull rod of 8 corresponding position of fixed pin at, and
Stay rod pin 10 is inside sliding rail 9, and two 5 other sides of strut and expansion board 6 are flexibly connected, and expansion board 6 is crushing shell 7 on one side, expands
Open upper welding crushing shell 7 on the outside of plate 6, it is only necessary to drill bit 2 be crept into ground, while tensile ties 4, the crushing shell 7 on expansion board 6
It will open, drillstock 3 is followed to rotate, reaming be carried out to the drilling on ground, to realize the purpose of ice-breaking.
Certainly, above-mentioned technical proposal is preferred forms of the invention, under without departing from spiritual background of the invention
Made any improvement, is within the scope of the present invention.
