Abstract
The utility model relates to a hand-push support of an earth drill, characterized of including a bottom frame capable of being passed through by a drill of the earth drill to work, two armrest levers fixed on the bottom frame vertically, a slide cover is arranged on a drill frame locating on the armrest levers, the top of the armrest levers is provided with a hand-operated lifting mechanism, the drill frame is driven by the lifting mechanism to lift along the armrest levers, the bottom of the armrest levers are fixed on two rollers through the support. the utility model has characteristics of an ingenious structure, a professional design, a very convenient localization and movement, and the support is capable of supporting the earth drill stably; the support of the invention changes the traditional power earth drill that there is need to carry the earth drill by a shoulder or hands, the inventive earth drill may move everywhere by means of the two rollers, the earth drill is not only capable of walking on a plain road, also walking on a mountain road and motte, thus the urban gardens and the mountanious region planting are all convenient.
Description
Technical field:
The utility model belongs to the garden engineering mechanical field, particularly a kind of hand push support that is matched in the power trench excavator.
Background technology:
Existing trenching machine can be divided into two classes, and a class is a major works equipment, as excavator, is applicable to needing of major works excavation, and its environmental disruption to periphery is also bigger, generally is not used in the operations of digging pit such as gardens tree planting, municipal electric pole.For this reason, the way that the excavation in tree planting or some small-sized tunnels still adopts manpower to excavate, the dealer also creates some minitype motivation trenching machines, as the patent No. 200620096725.6, it as power, drives the drill bit rotation of digging pit by miniature gasoline engine, finishes the power operation of digging pit.This equipment has the characteristics that manpower is efficiently digged pit that need not, but need have certain weight, portable moves very inconvenience everywhere, but also needs both hands defective such as to set upright, and how to improve the object that promptly becomes the utility model research.
Summary of the invention:
The purpose of this utility model is to design a kind of trench excavator hand push support that trench excavator moved and drove the trench excavator lifting that carries.
Technical solutions of the utility model are achieved in that a kind of trench excavator hand push support, it is characterized in that comprising that one can allow the trench excavator drill bit pass the underframe of operation, uprightly be fixed on two bars on the underframe, drill bit frame on two bars is slidingly located in, bar top is provided with hand elevating mechanism, the drill bit frame is driven along the bar oscilaltion by elevating mechanism, and bar lower end rear side is fixed with two rollers by support.Can promote trench excavator by two rollers and move the hard work that alleviates portable shoulder thick stick everywhere.
Described hand elevating mechanism comprises a rotating shaft that is positioned at two bars upper ends, be fixed on a drive sprocket in the rotating shaft and a rocking handle, driven sprocket, that is positioned on the underframe is set in the chain between drive sprocket and the driven sprocket, the drill bit frame is fixed on the chain, follows chain and moves up and down.Move up and down by chain drive drill bit frame, satisfy the drill bit lifting and finish the work flow of digging pit.
Be fixed with a spragging gear in the described rotating shaft, a resilient pin can insert and form braking in the teeth groove.After making the lifting of drill bit frame put in place reliable location is arranged, be beneficial to transfer to other local continuation operation.
Described underframe becomes rectangular-shaped structure, is formed by the steel pipe bending, and it is perverse respectively to be fixed with a location on four edges downwards.Make the hand push support can reliable and stablely be positioned any ground, do not rotate the arbitrarily worry of swing of support because of drill bit.
The utlity model has structure ingenious, reasonable in design, can reliable and stable carrying trench excavator, location and move all characteristics very easily, change the portable hard work of traditional power trench excavator shoulder thick stick, not only can carry out in the Plain road, also can walk among the woods of Yushan Hill road city trees and shrubs, mountain region two facilities of planting trees.

The specific embodiment:
See figures.1.and.2, a kind of trench excavator hand push support has added drill bit 31 and gasoline engine gearbox 32 on drill bit frame 3 in this legend, after installing gasoline engine on the gearbox 32 a hand propelled trench excavator.It comprises that one can allow the trench excavator drill bit pass the underframe 1 of operation, uprightly be fixed on two bars 2 on the underframe, 1 one-tenth rectangular-shaped structure of underframe is formed by the steel pipe bending, it is perverse 11 respectively to be fixed with a location on four edges downwards, make support can reliable and stable location on the ground; Two bars, 2 upper ends fold backward, form handrail 21, are arranged with antiskid glue sleeve 22 on 21 ones on handrail, and bar 2 lower end rear sides are fixed with two rollers 4 by support.Drill bit frame 3 is slidingly located on two bars 2, and bar 2 tops are provided with hand elevating mechanism, and drill bit frame 3 is driven along the bar oscilaltion by elevating mechanism.This hand elevating mechanism can adopt following two kinds of schemes:
One: the hand elevating mechanism of chain sprocket as shown in the figure.This hand elevating mechanism comprises a rotating shaft 5 that is positioned at two bars, 2 upper ends, be fixed on a drive sprocket 52 in the rotating shaft and a rocking handle 51, driven sprocket 53, that is positioned on the underframe 1 is set in the chain 54 between drive sprocket 52 and the driven sprocket 53, drill bit frame 3 is fixed on the chain 54, follows chain 54 and moves up and down.Rocking handle 51 directly is fixed on the end of rotating shaft 5, and one hand is being held up handrail 21, and one-handed performance rocking handle 51 can drive 3 oscilaltions of drill bit frame, finishes the operation of digging pit.
In this structure, be fixed with a spragging gear 55, one resilient pins 56 in the rotating shaft 5 and can insert formation braking in the teeth groove.Stopping operation, the built on stilts that drill bit can be raise then inserts resilient pin 56, makes crown height be controlled, and makes things convenient for trench excavator to move or collects, and when moving to when digging pit ground, transfers to resilient pin 56 once more, but rotating shaft 5 flexible operating again.
Its two: be the hand elevating mechanism that bolt and nut cooperates.This hand elevating mechanism comprises that one is positioned at rocking handle, two ends on two bars, the 2 upper end cross bars and is positioned screw rod, on cross bar and the underframe 1 respectively and is screwed in nut on the screw rod; rocking handle is by pair of meshing bevel gear and screw rod formation drive connection; the drill bit frame is fixed on the nut, follows nut and moves up and down along screw rod.
Hand elevating mechanism is the simplest with above-mentioned two examples; certainly also get rid of other such as jack structure, belt and belt pulley fit structure and quadric chain etc.; allly drive drill bit frame lifting scheme person with this similar scheme and all should belong to equivalent technologies, still belong to the row of the utility model protection.
