Abstract

The utility model relates to a self-motion double stirring extrusion machine, mainly comprising an electric motor, a speed reducer, a bearing seat, a clay barrel, double screw stirrers, a core print, a reducer pipe, an extrusion die port, a machine frame, a guiding axle and a rolling wheel. The self-motion double stirring extrusion machine can produce pipes continuously on the spot by using lime soil or other similar materials and drive a pipe making machine to move forward depending on the reacting force generated in making pipes, so no external force as traction is needed. Compared with the existing underground concrete-pipe extrusion machine, the self-motion double stirring extrusion machine has the advantages of small size, light weight, small vibration, small friction, high pipe making speed and easy operation.

Description

Self-motion double stirring extrusion

The utility model relates to a kind of tuber of continuous tubulation at the scene.

It is that CN88208940, denomination of invention are the utility model patent of " underground concrete-pipe extruder " that the utility model applicant has obtained the patent No..Underground concrete-pipe extruder remains in actual use in the some shortcomings part, mainly is that volume is big, frictional resistance is bigger, and energy consumption is many, and single screw feeder drives core print and rotates together, the stainless steel substrates serious wear on core print surface not only, and also the vibrations of machine are bigger.

The purpose of this utility model overcomes the deficiencies in the prior art part exactly, and a kind of twin screws extruding tubing machine is provided.This machine can utilize the continuous on the spot tubulation of grey soil material or other similar material.

The utility model mainly comprises motor, decelerator, bearing block, mud cylinder, twin screws, core print, reducer pipe, extrusion mould-outlet, frame, the axis of guide, rolling wheel and wheel.Screw feeder is made up of screw conveyor shaft and helical blade, and two screw conveyor shafts are parallel to be settled and reverse rotation, the opposite and mutual dislocation insertion of the helical blade rotation direction on two screw conveyor shafts.Core print is made of core print body and core print blade two parts, and the core print body is the cavity cylinder, and the core print blade is a spade, forms two identical cone spaces between reducer pipe and core print blade, and the core print blade can be fixed on the reducer pipe.Mud cylinder section configuration ovalize or Long Circle, for reducing frictional resistance, the mud cylinder tilts to be lifted away from ground, and the tiltangle of mud cylinder is 3-8 °.Rolling wheel is contained in frame the place ahead, and its width is greater than extrusion mould-outlet and ground contact width, because machine weight mostly concentrates on the rolling wheel, rolling wheel can carry out the seamless compaction by rolling to the irrigation canals and ditches bottom surface, and can adjust direction by the axis of guide and handle.The section configuration of extrusion mould-outlet is the shape of a hoof of sub-circular.For ease of when shutting down the grey earth material in the die orifice being drawn out, extrusion mould-outlet is divided into patrix and counterdie again, counterdie can be directly and reducer pipe be welded into one, patrix is fixed by bolts on the counterdie, and connects together with bolt and reducer pipe.Be power and the vibrations of further reducing friction, one wheel pairs be housed in mud cylinder two sides.

Be described further below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is extrusion mould-outlet shape figure;

Accompanying drawing 3 is an A-A profile among Fig. 1.

Core print body 16 external diameters be φ 170mm, extrusion mould-outlet 15 internal diameters for φ 310mm(be that the interior external diameter of made pipe is respectively φ 170mm, φ 310mm).Motor 7 is 7.5 kilowatts, and by belt pulley connection decelerator 6, decelerator 6 adopts two utmost point speed changes, and the twin screws rotating speed is 40 rev/mins.Screw feeder is made of screw conveyor shaft 11 and helical blade 12, screw conveyor shaft 11 diameter phi 120mm, and helical blade 12 high 60mm, two screw feeder helical blades, 12 mutual dislocation are inserted 18-22mm to strengthen extruding, and two screw feeders support by bearing block 8.Mud cylinder 10 section configurations are oval, and there is charging aperture 9 mud cylinder 10 1 ends top, and mud cylinder 10 tilts to be lifted away from ground, and tiltangle is 3-8 °.Core print blade 13 is a spade, directly is welded on the reducer pipe 14.Rolling wheel 2 is contained in frame 5 the place aheads, and rolling wheel 2 width are 250-350mm, and rolling wheel 2 can be adjusted the grasp direction by the axis of guide 4 and handle 3, a pair of small wheels 1 also is housed with the resistance of further reducing friction in mud cylinder 10 two sides.The tuber speed of travel be 0.7-1 rice/minute.

During use this tuber is put into the irrigation canals and ditches that dig, starter motor adds the grey earth material of mixing, and the dirt pipe is from the extrusion mould-outlet moulding and fall into the irrigation canals and ditches bottom surface, and the dirt pipe produces a reaction force to tuber and promotes the tuber reach simultaneously, need not external force traction.

This machine is compared with intrinsic underground concrete-pipe extruder, and volume is little, in light weight, center of gravity is low, the vibration is little, and frictional resistance is little, and tubulation speed is fast, but save electric power 30% uses operation easily.
