Abstract

The utility model relates to a light multipurpose driller, which is provided with a squeezing drill bit in a shape of double cones and a set of a hand shaking mechanical device, wherein, the two bottoms of the double cones are coincident, the hand shaking mechanical device can conduct the operation of strong pressurizing drilling, and the hand shaking mechanical device is convenient to conduct the operation of drilling receding lift. The utility model can realize the dry drilling operation in an operational field without a water source and can be used for the occasions of the digging and construction of water wells for living and water wells for garden irrigation, the geologic sampling, the grout drilling of dams, etc.

Description

Multipurpose light driller

The utility model belongs to a kind of trepan, especially for use in the light-duty trepan of dirt bed sink wells.

In the known technology, power is at the light-duty trepan below 10 horsepowers, and it keeps the means of creeping into to deep layer is to come drill bit is exerted pressure by fuselage deadweight or operator's body weight, and constructing operation wastes time and energy, and this kind rig is water and bores rig, must provide recirculated water to use.The small-sized drill that Canada CANTERRA Engineering Co., Ltd, U.S. MARRLONTROLS and DEEPROCK company produce promptly belongs to this type of.In anhydrous regional drilling well, prepare recirculated water and be unusual difficulty, no recirculated water can not Cheng Jing, even the water source is arranged, drilling well in the sandy soil layer, above-mentioned rig is also inapplicable.

The purpose of this utility model is to propose a kind of light and flexible and be adapted to different soil and the light multipurpose way trepan that need not use recirculated water, to overcome the defective of known technology.

Light multipurpose trepan described in the utility model, it is to be assembled together and to be fixed on the slip support by motor, the PWTN drilling part part of unifying that its fuselage main body constitutes, two slip caps of slip support are sleeved on two root posts of described trepan frame, of the present utility model being characterised in that:

A, on described light multipurpose trepan, the hand mechanical device that drives the fuselage lifting is installed, the trepan lifting pressurized operation mechanism that it is made up of the chain, sprocket wheel, mechanical reduction gear and the handle that are installed on fuselage and the frame;

The parts that creep into of B, described light multipurpose trepan are a kind of Pressing drills, and the form of structure of this Pressing drill is:

(I) bit body is the double cone body that overlapped at two ends, in order to strengthen drilling duty, be added with hard material mound shape thrust at lower cone bit point of the drill position, be added with helical form hard material sword sheet along the lower cone surface, be added with strip hard material thrust along maximum outer rim place between the drill bit waist;

(II) bit body is hollow, be penetrated with the overman bit handle along its direction of axis line, the drill bit tip is a solid conical, and its outstanding contiguous block in awl bottom surface stretches to the bit sub mouth of pipe, links with bit sub with bolt, resistance when promoting in order to reduce drill bit, bolt pin-and-hole on the contiguous block is a slot, and when drill bit promoted, the tip and the mouth of pipe were separated, make air feed the shaft bottom immediately, eliminate negative pressure.

Light-duty trepan described in the utility model can be installed the water inlet assembly so that carry out water and bore operation above drilling rod; Augers also can be installed carry out the disturbance soil sampling.

Advantage of the present utility model and effect are that it can realize in anhydrous subject job place being widely used in living water use well, vegetable garden irrigation well, building and geological sampling, occasions such as dam grouting boring by dry drilling.Its power of creeping into is strong, promotes easily compact conformation, mobile flexible, easy to operate, high efficiency.

Specific embodiment of the utility model, as shown in drawings.

Fig. 4 is the hand deceleration device structure chart of a present embodiment left view.

Fig. 5 is a present embodiment Pressing drill topology view.

Rig shown in the drawings, Diesel engine (1) by 4 horsepowers (2600 rev/mins of rotating speeds) is done power, by the centrifugal clutch on its main shaft (6), connect the belt pulley power train (7) of gearratio i=2.37 and the gear reduction box (8) of gearratio i=25.3, thereby driving drill bit (16) is done and is crept into action.By motor (1), clutch (6), belt pulley power train (7), reduction box (8), water inlet assembly (10) and drill bit (16) are assembled into one and are installed on the slip support (9), slip cap (15) about support (9) is socketed in about frame (4) on two root posts, makes support do lifting moving along principal post.The fixedly connected point (3 of one or two couple on the frame (4), 18) connecting between two chains (17), chain (17) again with slip cap (15) on sprocket wheel (13,14), the jockey sprocket (2 on the frame (4), 5,20,19) and hand mechanical reduction gear (11) link, promote the pressurization mechanical operating mechanism thereby constitute trepan, mechanical reduction gear (11) drives two groups of " gears that are bound up on the axis (21) by a pair of handle (12)

Sprocket wheel " gear (23,24) in the transmission system, the lifting that sprocket wheel (25,26) is controlled well bore with creep into.On the primary pinion that joins with handle (12) stop limited block (22) is housed also, so that when pausing operation, make rig rest on a certain permanent position, in carrying out operating process, when sprocket wheel (13) was stressed, rig promoted, when sprocket wheel (14) was stressed, rig descended.The operation of this rig can be single, double or many people mode of operation, no matter is which kind of mode of operation, can guarantee that all the drilling rod both sides evenly put forth effort simultaneously.Whole lifting water booster system can make the same specification rig of this pressure ratio known technology that creeps into increase more than 10 times.

Pressing drill shown in the drawings runs through the hollow bipyramid bodily form bit body that two ends overlapped by overman bit handle (27), lower cone surface (33), stud with helical form carbide alloy sword sheet (32), the most advanced and sophisticated position (35) of lower cone studs with carbide alloy mound shape thrust (36), have slot (38) on the contiguous block (37) of most advanced and sophisticated position (35) and bit sub (27), be connected with bolt (34).In upper cone (28) surface soldered bolt shape steel wire (29) is arranged,, stud with bar shaped carbide alloy (31) along maximum outer rim (30) between the bit body waist.
