Description

Rock boring drill frame and combined drill body

Technical Field

The utility model belongs to the technical field of soil drilling tool, a rock boring drilling rig and combination drill body is related to.

Background

The drill is a tool for drilling through holes or blind holes in solid materials and reaming existing holes. Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills. Reamers and reamers are not capable of drilling solid materials, but they are also traditionally classified as drills. During digging, the drill bit rotates around the vertical shaft and moves axially. The soil is cut under the action of torque and axial force of the drill bit, is broken and loosened under the action of extrusion and centrifugal force of the working blades, forms soil flow and presses the pit wall, and meanwhile, the soil flow is lifted along the page and conveyed to the ground surface. When the soil flow moves to the position without pit wall blocking, the broken soil is thrown to the periphery of the pit due to the action of centrifugal force, and the whole pit digging process is completed; although the drill bit can realize the function of drilling, when the drill bit is damaged in the drilling process, people can only completely replace the drill bit, and the material for manufacturing the drill bit is wasted.

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.

The mounting hole 110 is formed in the mounting column 100, the mounting hole 110 is integrally in a straight prism shape, the side face of the mounting column 100 is provided with the limiting hole 120, the limiting hole 120 is communicated with the mounting hole 110, during mounting, a shaft corresponding to the mounting hole 110 on a drilling machine needs to be inserted into the mounting hole 110 by people, and the shaft is inserted into the limiting hole 120 through a bolt, so that the shaft is connected with the mounting column 100 in a positioning mode.

Example two

As shown in fig. 1 to fig. 3, the present embodiment is different from the first embodiment in that the present embodiment discloses a specific structure of a tool, and the tool is mounted on a tool mounting assembly 300.

Specifically, the cutter body 400 is detachably connected in the cutter mounting assembly 300 of the rock boring rig, the cutter body 400 comprises a drill string 410 and a drill bit 420, the drill string 410 is fixedly connected with the drill bit 420, and the drill string 410 is provided with threads, when the drill string 410 of the cutter body 400 is installed, people need to insert the drill string 410 of the cutter body 400 into the through hole 311 of the cutter mounting assembly 300 and connect the drill string 410 and the through hole 311 with threads, so that the cutter body 400 can be stably connected in the corresponding drill sleeve 310.

After the drill string 410 is installed in the corresponding drill bushing 310, a certain included angle is formed between the drill bit 420 and the horizontal plane, so that the drill bit 420 can smoothly chip soil; secondly, the bit 420 tapers outwardly from the end near the drill string 410, thus further enhancing the effect of the bit 420 in cutting the soil.
