Abstract

The utility model relates to a dumb well digging mechanism and comprises a housing frame, an inner frame, and a bucket which is connected with the inner frame. The technic plan shows that the housing frame is fixed with a main stroke cylinder of which a piston rod is provided with a sprocket with one end fixed on a chain of the inner frame and the other end connected with the chain. The bucket and a control mechanism are mounted on the inner frame. When in working, the utility model firstly leads the main stroke cylinder to act and then the chain drives the inner frame to move. The stroke of the inner frame movement is as two times as the piston rod stroke of the main stroke cylinder, thereby the volume of the utility model is largely reduced if the same stroke needs to be realized, compared with the prior art. Furthermore, adopting the cylinder driving can also largely increase the digging capacity of the utility model.

Description

The sink hole digging mechanism

Affiliated technical field

The utility model is a kind of sink hole digging mechanism.

Background technology

The cleaning work of road both sides sink hole (road sand sediment trap) in China city at present, the overwhelming majority is by manually finishing.Because the space of sink hole is narrower and small, is difficult to be implemented in the mechanized in the well, makes cleaning work waste time and energy; And the dirt that cleans out can not in time be transported, and has both influenced traffic and also environment has been caused pollution.Though corresponding excavation cleaning equipment is arranged abroad, can't use because domestic systems such as sewage conduct are incompatible with it.The sink hole digging mechanism of design adopts the tipping bucket type structure of chain drive before me, and each tipping bucket moves successively can realize continuous excavation.But this excavator can not excavate half-dried or absolutely dry sand sediment trap because the restriction of chain structure can not bear bigger impact force, thereby digging force is little, exists certain limitation in the use.In addition, the stroke of its bucket of digging mechanism of this structure is identical with the chain stroke, because sink hole is darker, so the length of its framework is bigger, and not only cost improves, and equipment damages easily, and it is big to take up room, and is difficult for carrying with car.

Summary of the invention

The purpose of this utility model is: rational in infrastructure, volume is less but stroke is big, be subjected to the bigger sink hole digging mechanism of force intensity.

The utility model comprises its outside framework and inner frame and the bucket that is connected with inner frame, its technical scheme is: be fixed with main stroke oil cylinder on the outside framework, on its piston rod sprocket wheel is arranged, an end be fixed on the inner frame the chain other end be connected, bucket and controlling organization thereof are housed on the inner frame.The utility model at first makes main stroke cylinder action when work, chain drives the inner frame motion, and the stroke of inner frame motion is the twice of the piston rod stroke of main stroke oil cylinder, therefore, if will realize stroke same as the prior art, volume of the present utility model then reduces greatly.And, adopt hydraulic oil cylinder driving also can improve mining ability of the present utility model greatly.

For the restriction that remedies main stroke oil cylinder piston pole length may cause the situation of stroke deficiency, can auxiliary stroke oil cylinder be installed on the inner frame in the utility model, bucket and controlling organization thereof are installed on the piston rod of auxiliary stroke oil cylinder.At this moment, bucket of the present utility model still can adopt original type of belt drive, also can adopt following form: described bucket comprises the bucket that two relative openings and middle part connect by bearing pin, and the piston rod of bearing pin and auxiliary stroke oil cylinder is connected; The controlling organization of bucket comprises two bucket upper surface outer side edges by two groups of connecting rods that are connected with the bearing pin of centre, and bearing pin is connected with the piston rod that cylinder body is fixed on the control oil cylinder on the auxiliary stroke oil cylinder piston bar.But the movable dump skip of the bucket peripheral hardware of this form, also can adopt the dump skip of following form: be fixed with cross slide way on the outside framework, dump skip is installed on the outside framework by this guide rail, and unloading fuel tank is arranged on the outside framework, and the axle of its piston rod and dump skip rear side flexibly connects.

For making bucket carry out work or make the inner frame location when not working, can corresponding installing and locating oil cylinder in the both sides, bottom of outside framework, it is corresponding with inner frame to have pressure head and position on its piston rod.
