Description

Technical Field

[0001] The present invention belongs to the technical field of geotechnical engineering, and more specifically, particularly relates to a drilling device used for geotechnical engineering investigation. Background Art

[0002] Drilling is one of the main means of geotechnical engineering investigation. A drilling rig is used to drill downward from the surface to form a cylindrical borehole in the stratum to identify and divide the stratum. Cores, mineral samples, and soil samples can be obtained from different depths in the borehole for analysis and research to determine the physical, mechanical properties and indicators of rocks and soil layers and provide design needs. Drilling equipment is currently needed for geotechnical engineering investigations.

[0003] As disclosed in the publication number: CN220791132U, a drilling and collection equipment for geotechnical engineering survey is disclosed, including a box body, a second slide groove is opened on the inner wall of the box body, a first support plate is slidably connected to the inner side of the second slide groove, a second motor is fixed to one side of the bottom of the first support plate, two support blocks are fixed to one side of the bottom of the first support plate, a second support plate slidably connected to the inner side of the second slide groove is fixed to the bottom of the support block, a reducer is fixed to one side of the bottom of the second support plate, when the heavier drilling equipment needs to be moved, only the output shafts of the first motors need to drive the screw rods to rotate, so that the two limit blocks are close to each other, and at the same time, the support rods push the fixed blocks downward to move downward, and at the same time, the connecting frame, the rotating shaft and the pulley move downward, and when the multiple pulleys are against one side of the ground, the drilling equipment can be moved in parallel at this time, the operation is simple and convenient, the convenience of moving the drilling equipment is improved, and the use cost of the drilling equipment is reduced.

[0004] Based on the above patent solution and existing related technologies, the drilling equipment currently used for geotechnical engineering survey still has the following problems: 1. After drilling is completed, the staff needs to manually clean the drilling bit, and the drilling bit cannot be automatically cleaned; 2. Usually, the positioning is achieved by relying on the braking function on the roller, which makes the equipment easy to move during drilling, affecting the drilling effect; 3. Generally, there is a lack of a pushing structure, which makes it easy for the rock and soil residue after drilling to enter the drilling hole when the drilling bit is pulled out, increasing the subsequent cleaning time. To this end, we provide a drilling equipment for geotechnical engineering survey to solve the above problems. Summary of the invention

When the staff starts the two linear electric cylinders A202 and the drive motor 302, the drilling drill bit 304 moves slowly downward, realizing the automatic drilling of the rock and soil. When the output shafts of the two linear electric cylinders A202 extend, the two drilling positioning rods 103 are automatically inserted into the two positioning circular holes 2051, which limit the rectangular positioning frame 205, so that the rectangular positioning frame 205 can only move downward along the two drilling positioning rods 103 to avoid the drilling drill bit 304 from shaking; when the staff separates from the two pedal stabilizing frames 402, the two pedal stabilizing frames 402 automatically move upward under the action of the four spiral springs B404, so that the bottom of the eight circular stabilizing rods 403 is higher than the bottom of the four moving rollers 104; after the drilling is completed, when the staff starts the drive motor 302, the linkage cleaning frame 30 3 can contact with two V-shaped cleaning racks 102; when the linkage cleaning rack 303 contacts with the V-shaped cleaning rack 102 on the left, the movable mounting plate 204 drives the drilling drill bit 304 to move to the right; when the linkage cleaning rack 303 separates from the V-shaped cleaning rack 102 on the left, the movable mounting plate 204 is reset to the left under the action of four spiral springs A206; when the linkage cleaning rack 303 contacts with the V-shaped cleaning rack 102 on the right, the movable mounting plate 204 drives the drilling drill bit 304 to move to the left; when the linkage cleaning rack 303 separates from the V-shaped cleaning rack 102 on the right, the movable mounting plate 204 is reset to the right under the action of four spiral springs A206; The movable mounting plate 204 drives the drilling bit 304 to move back and forth left and right, which facilitates the automatic falling of the rock and soil on the drilling bit 304, and realizes the rapid cleaning of the drilling bit 304; then the staff retracts the output shafts of the four linear electric cylinders B501. At this time, the two arc-shaped auxiliary plates 504 move outward at the same time, which automatically pushes the rock and soil residue after drilling, and prevents the rock and soil residue from entering the drilling hole when the drilling bit 304 is pulled out; after the equipment is used, the staff can pull the two arc-shaped auxiliary plates 504 upwards to make a certain distance between the bottom of the two arc-shaped auxiliary plates 504 and the ground, and prevent the bottom of the two arc-shaped auxiliary plates 504 from bumping.
