Fig. 3 is a schematic view of the structure of the cutter body.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Example one
As shown in fig. 1-2, the rock boring drill rig of the present invention includes a mounting post 100, a chip removal plate 200, a cutter mounting assembly 300 and an included angle a.
The side of the mounting post 100 is provided with a pair of chip removal plates 200, the two chip removal plates 200 are rotationally symmetric about the central axis of the mounting post 100, the bottom edge of each chip removal plate 200 is provided with a plurality of chip mounting assemblies 300, the central axis of each chip mounting assembly 300 intersects with the bottom surface of the mounting post 100 to form an included angle, and the included angle a is an acute angle, before work, people need to mount the mounting post 100 on a drilling machine, when the drilling machine drives the mounting post 100 to operate, because the two chip removal plates 200 are fixedly connected to the side of the mounting post 100, the two chip removal plates 200 rotate about the center of the mounting post 100, because the chip mounting assemblies 300 are provided with cutters, the cutters can cut soil contacting with the cutters, secondly, in the utility model, the central axis of each chip mounting assembly 300 intersects with the bottom surface of the mounting post 100, and the included angle a is an acute angle, so that the corresponding cutters mounted on the chip mounting assemblies 300 have the same included angle a with the, therefore, the cutter can easily cut soil and the cutting efficiency of the cutter to the ground is accelerated.
Dress cutter unit 300 all includes drill bushing 310, all sets up in every drill bushing 310 and has the internal screw thread to perforate 311, consequently, during the installation, people need install the cutter in the drill bushing 310 that corresponds, because of the contained angle a that each drill bushing 310 corresponds is close to the outside crescent of one end of erection column 100 by chip removal board 200 for the cutter that is close to erection column 100 one end is from inside to outside, and the contained angle that this cutter corresponds crescent, makes the smear metal soil that the cutter can relax.
Because of two chip removal boards 200 all set up and are the heliciform, and all drill bushings 310 are all installed on the bottom edge of chip removal board 200, make all drill bushings 310 that are located on same chip removal board 200 wholly be the heliciform, consequently, after the cutter is in smear metal soil, by the orbit of drill bushing 310, move to the chip removal board 200 that corresponds, and chip removal board 200 this moment is in the operation in-process, make chip removal board 200 can easily guide out soil, thereby reduce and leave over in the hole that drills by the soil of smear metal, thereby ensure this rock boring drill rig of use that people can be stable.
Two adjacent drill bushings 310 are connected through the fixing block 320, and the firmness between the two drill bushings 310 is effectively improved through the arrangement of the fixing block 320, and the firmness between the drill bushings 310 and the chip removal plate 200 is improved due to the fact that the drill bushings 310 are fixedly connected with the corresponding chip removal plate 200.
