Fig. 2 is a schematic diagram of the internal structure of the present invention.

Detailed Description

The invention is further described with reference to the drawings and the detailed description. For convenience of description, in the present invention, the direction same as the rotation direction is front, the direction opposite to the rotation direction is rear, the direction toward the axis is inner, and the direction away from the axis is outer.

As shown in fig. 1 and 2, the present invention comprises a rotation shaft 1, an inner ring 4, a middle ring 5, an outer ring 2 and a shift lever 6.

The rotating shaft 1, the inner ring 4, the middle ring 5 and the outer ring 2 are coaxially distributed from inside to outside, and the horizontal sections of the rotating shaft, the inner ring 4, the middle ring 5 and the outer ring are of concentric circle structures.

The inner ring 4 is fixed on the rotating shaft 1, and the inner ring 4 is driven to synchronously rotate through the rotating shaft 1. The deflector rods 6 are provided with a plurality of numbers and are evenly distributed on the middle ring 5. The middle position of the deflector rod 6 is hinged with the inner wall of the middle ring 5, the front end of the deflector rod 6 bends inwards, and the rear end of the deflector rod 6 bends outwards to form a hook body structure 9. An opening 8 is arranged on the middle ring 5 corresponding to the hook body structure 9, and the hook body structure 9 extends out of the opening 8 and is exposed outside the middle ring 5. The inner side surface of the outer ring 2 is provided with a series of teeth 11, the tail end of the hook body structure 9 is hooked on the teeth 11, and the middle ring 5 can drive the outer ring 2 to rotate under the action of the hook body structure 9 and the teeth 11. The outer side surface of the inner ring 4 is provided with a series of lugs 7, the number and the positions of the lugs 7 correspond to the deflector rod 6 one by one, and in a natural state, the lugs 7 are propped against the inner side of the rear end of the deflector rod 6, so that the deflector rod hook body structure 9 is prevented from being separated from the teeth 11 due to the inward rotation of the rear end of the deflector rod 6. The inner ring 4 is connected with the outer ring 2 through a spring 10, and the middle ring 5 is pulled to rotate through the spring 10 when the inner ring 4 rotates. The front end of the spring 10 is fixed on the projection 7, and the rear end of the spring 10 is fixed on the middle ring 5. To facilitate the mounting of the spring 10, a series of fixed blocks 12 are provided on the inner side of the middle ring 5, and the rear end of the spring 10 is fixed to the fixed blocks 12.

The outer ring 2 is of a conical surface structure with a thin lower part and a thick upper part, a series of tool bits 3 are arranged on the outer side surface, and rock soil is excavated through the tool bits 3.

The operation flow is as follows: during excavation, the power device drives the rotating shaft 1 to rotate, the driving shaft drives the inner ring 4 to rotate, the inner ring 4 pulls the middle ring 5 to rotate through the spring 10, the middle ring 5 drives the outer ring 2 to rotate through the deflector rod 6, and the outer ring 2 excavates soil through the cutter head 3, so that the reaming effect is realized. When the rock is excavated to a rock layer, the cutter head 3 is clamped and cannot rotate continuously, the inner ring 4 pulls the middle ring 5 through the spring 10, the middle ring 5 cannot rotate, the spring 10 is elongated, the lug 7 rotates to the front end of the deflector rod 6, the front end of the deflector rod 6 is jacked outwards through the lug 7, so that the rear end of the deflector rod 6 moves inwards, the deflector rod hook body structure 9 is separated from the teeth 11 of the outer ring 2, the resistance of the middle ring 5 disappears after the separation, the middle ring 5 rotates rapidly under the action of the tension of the spring 10, meanwhile, the hook body structure 9 at the rear end of the deflector rod 6 extends outwards, the deflector rod 6 extends and then hits the next tooth 11 of the outer ring 2, the middle ring 5 and the outer ring 2 are impacted, meanwhile, the impact force acts on the rock through the outer ring 2 and the cutter head 3, the impact effect on the rock is formed, and the rock is crushed through the repeated impact effect, thereby realizing the reaming function.

The utility model is suitable for a not too high rock layer operation of hardness.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
