Background technology

At present, tunnel drill digging machine is all by driving a large cutterhead rotary cutting to complete, can only forming a circular tunnel during cutterhead rotary cutting.

Summary of the invention

The utility model has made up the shortcoming of above tunnel drill digging machine, and a kind of Elliptical Tunnels drilling and digging machine is provided.

The utility model is achieved by the following technical solution:

A kind of Elliptical Tunnels drilling and digging machine, motor is located in the middle of drilling and digging machine, motor left end is fixed on baffle plate, motor right-hand member is provided with the 3rd gear, the first gear is meshed on the 3rd gear top, the second gear is meshed in bottom, and the first gear is threaded onto the first helical axis by internal thread cover in the middle of it, and the second gear is threaded onto the second helical axis by internal thread cover in the middle of it; The first hinged the second beam in helical axis upper end, hinged the 3rd beam in the second helical axis lower end; Hinged the first arm of force upper end of the first beam right-hand member, the first beam left end is with a certain distance from the hinged baffle plate of the first cutterhead, hinged the second arm of force upper end of the second beam right-hand member, the second beam left end is with a certain distance from the hinged baffle plate of the second cutterhead, hinged the first arm of force lower end of the 3rd beam right-hand member, the 3rd beam left end is with a certain distance from the hinged baffle plate of the 3rd cutterhead, hinged the second arm of force lower end of the 4th beam right-hand member, and the 4th beam left end is with a certain distance from the hinged baffle plate of four blade dish; The cross section of the first cutterhead and four blade dish is semicircle, and the cross section of the second cutterhead and the 3rd cutterhead is rectangle.

The utlity model has following feature:

Every two adjacent cutterhead relative motions in the utility model the first cutterhead, the second cutterhead, the 3rd cutterhead, four blade dish, can be by the boulder grating in earth.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that A-A of Fig. 1 is to view.

In figure: 1, the first cutterhead, the 2, first beam, the 3, second cutterhead, the 4, second beam, 5, the 3rd cutterhead, the 6, the 3rd beam, 7, four blade dish, 8, the 4th beam, 9, first arm of force, 10, second arm of force, 11, the first helical axis, the 12, second helical axis, the 13, first gear, 14, the second gear, 15, motor, 16, baffle plate, 17, the 3rd gear, 18, shell, 19, cutter tooth.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment motor 15 is located in the middle of drilling and digging machine, motor left end is fixed on baffle plate 16, motor right-hand member is provided with the 3rd gear 17, the first gear 13 is meshed on the 3rd gear top, bottom is meshed the second gear 14, the first gears and by internal thread cover in the middle of it, is threaded onto the first helical axis 11, the second gears and is threaded onto the second helical axis 12 by internal thread cover in the middle of it; Hinged the second hinged the 3rd beam 6 in beam 4, the second helical axis lower ends in the first helical axis upper end; Hinged the first arm of force 9 upper ends of the first beam 2 right-hand members, the first beam left end is with a certain distance from the hinged baffle plate of the first cutterhead 1, hinged the second arm of force 10 upper ends of the second beam right-hand member, the second beam left end is with a certain distance from the hinged baffle plate of the second cutterhead 3, hinged the first arm of force lower end of the 3rd beam right-hand member, the 3rd beam left end is with a certain distance from the hinged baffle plate of the 3rd cutterhead 5, the 4th hinged the second arm of force lower end of beam 8 right-hand members, and the 4th beam left end is with a certain distance from the hinged baffle plate of four blade dish 7; The cross section of the first cutterhead and four blade dish is semicircle, and the cross section of the second cutterhead and the 3rd cutterhead is rectangle.

During the utility model work, commutator is controlled motor and is driven the 3rd gear to be rotated in the forward a few, then counter-rotate a few, repeatedly carry out, thus by the forward of the first gear and the second gear, rotate backward, drive the first helical axis and second right-hand member of helical axis reciprocating sliding the second beam and the right-hand member of the 3rd beam, the right-hand member of the second beam is by the right-hand member of the second arm of force push-and-pull the 4th beam, the right-hand member of the 3rd beam is by the right-hand member of first arm of force push-and-pull the first beam, so, the first cutterhead, the second cutterhead, the 3rd cutterhead, every two adjacent just relative motions of cutterhead in four blade dish, cutter tooth bores at the volley and scrapes out tunnel.
