Abstract

Provided is a rectangular drilling machine. A support beam is fixed on the lower portion of the rectangular drilling machine. A first motor is arranged at the right end of the support beam, a second motor is arranged at the left end of the support beam, a first output shaft is fixed at the lower end of the first motor, a first cam body is fixed at the lower end of the first output shaft, a first frame is arranged on the periphery of the first cam body, a second output shaft is fixed at the lower end of the second motor, a second cam body is fixed at the lower end of the second output shaft, and a second frame is arranged on the periphery of the second cam body. A connecting rod is fixed at the lowermost end of a drill rod, two sliding rods are fixed at two ends of the connecting rod respectively, the left end of each sliding rod penetrates through a sliding sleeve positioned on the first frame, the right end of each sliding rod penetrates through a sliding sleeve positioned on the second frame, and a plurality of T-shaped cutter heads are arranged on the lower portion of the first frame and the lower portion of the second frame. The two groups of T-shaped cutter heads positioned on the two frames are driven by the two cam bodies to perform reciprocating motion oppositely so that rectangular holes can be drilled.

Description

The rectangle auger

Technical field

The present invention relates to a kind of auger, particularly the rectangle auger used of a kind of earth drilling.

Background technology

At present, boring auger all is that the rotation by drill bit drills through a circular port, and some engineering need drill through some rectangular openings, and traditional rig is just helpless.

Summary of the invention

The present invention has remedied above blank, and a kind of rectangle auger is provided.

The present invention is achieved through the following technical solutions:

A kind of rectangle auger, brace summer is fixedly arranged at the bottom, and the brace summer right-hand member is provided with first motor, and the brace summer left end is provided with second motor; Fixedly there is first output shaft first motor lower end, fixedly there is first cam body first output shaft lower end, and the first cam body periphery is provided with first framework, and fixedly there is second output shaft second motor lower end, fixedly there is second cam body second output shaft lower end, and the second cam body periphery is provided with second framework; Drilling rod connecting rod fixedly arranged bottom, the two ends of connecting rod fixedly have a slide bar respectively, the left end of every slide bar passes the sliding sleeve on first framework, and the right-hand member of every slide bar passes the sliding sleeve on second framework, and first framework and the second framework bottom are equipped with several T type cutter heads.

The present invention has following characteristics:

The present invention by two cam bodies drive on two frameworks two groups of T type cutter heads in opposite directions, move back and forth, can be drilled to rectangular opening.

Description of drawings

The present invention is further illustrated below in conjunction with accompanying drawing:

Fig. 1 is structural representation of the present invention;

Fig. 2 is A-A view;

Fig. 3 is B-B view;

Among the figure: 1, first motor, 2, second motor, 3, drilling rod, 4, brace summer, 5, first output shaft, 6, second output shaft, 7, sliding sleeve, 8, slide bar, 9, connecting rod, 10, first framework, 11, second framework, 12, first cam body, 13, second cam body, 14, T type cutter head.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present invention, and brace summer 4 is fixedly arranged at these embodiment drilling rod 3 bottoms, and the brace summer left end is provided with first motor 1, and the brace summer right-hand member is provided with second motor 2; Fixedly there is first output shaft 5 the first motor lower end, fixedly there is first cam body 12 the first output shaft lower end, the first cam body periphery is provided with first framework 10, fixedly there is second output shaft 6 the second motor lower end, the second output shaft lower end fixedly has second cam body, 13, the second cam body peripheries to be provided with second framework 11; Drilling rod connecting rod 9 fixedly arranged bottom, the two ends of connecting rod fixedly have a slide bar 8 respectively, the left end of every slide bar passes the sliding sleeve 7 on first framework, and the right-hand member of every slide bar passes the sliding sleeve on second framework, and first framework and the second framework bottom are equipped with several T type cutter heads 14.

Described first motor and second motor are synchronous motor, and first motor just changes, the counter-rotating of second motor.

Described sliding sleeve is four, and two of the left side are fixed in the first framework top, and two of the right are fixed in the second framework top, and slide bar can slide in sliding sleeve.

When the present invention works, first motor is that just change in the center of circle with the driving shaft by first drive shaft, first cam body, second motor is center of circle counter-rotating with the driving shaft by second drive shaft, second cam body, first cam body and second cam body in rotation process, drive respectively first framework and second framework in opposite directions, back and forth side-to-side movement, two groups of T type cutter heads cut the soil layer pore-forming in motion process, pore-forming mud is discharged by the direct circulation system.
