Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] like Figures 1-4 As shown in the figure, this utility model discloses a rotary drilling bit soil removal device, including a drill cylinder 1, a cleaning mechanism, and a disassembly mechanism. The drill cylinder 1 has a receiving cavity 101. A base plate 2 is provided at the bottom of the receiving cavity 101. A rack 200 is fixedly provided at the bottom of the base plate 2. A through hole 201 communicating with the receiving cavity 101 is provided on one side of the rack 200. A hydraulic cylinder 3 is fixedly provided at the top of the drill cylinder 1. A countersunk hole 202 is provided at the top of the base plate 2. A groove communicating with the countersunk hole 202 is provided on the side wall of the through hole 201. Rotation within the countersunk hole 202 An insert rod 4 is provided, and a baffle 401 that matches the through hole 201 is fixedly provided on the side wall of the insert rod 4. The baffle 401 is embedded in the slide groove. The top of the insert rod 4 is provided with a groove 402, and the inner wall of the groove 402 is provided with a spiral groove 403. The output shaft of the hydraulic cylinder 3 is fixedly connected to a fixing rod 301, which is inserted into the groove 402. A protrusion 302 is fixedly provided on the side wall of the fixing rod 301, and the protrusion 302 is embedded in the spiral groove 403. The cleaning mechanism is provided on the fixing rod 301, and the disassembly mechanism is provided on the base plate 2.

[0026] In at least one embodiment, the cleaning mechanism includes a scraper 5, which is fixedly mounted on a fixed rod 301. The outer edge of the scraper 5 abuts against the inner wall of the receiving cavity 101. When the worker extends the fixed rod 301 by using the hydraulic cylinder 3, the scraper 5 scrapes away the soil in the receiving cavity 101, ensuring convenient cleaning of the soil.

[0027] In at least one embodiment, the disassembly mechanism includes an adjusting rod. The base plate 2 is provided with multiple sets of through holes 203 spaced apart along the circumference. The drill barrel 1 is provided with threaded holes aligned with the through holes 203. The adjusting rod passes through the through holes 203 and is threaded into the threaded holes. The operator can adjust the connection state of the base plate 2 and the drill barrel 1 by rotating the adjusting rod, which facilitates the installation and disassembly of the base plate 2 and the drill barrel 1 and makes the operation convenient.

[0028] In at least one embodiment, a limiting strip 102 is fixedly provided on the inner wall of the receiving cavity 101 in the vertical direction, and a limiting groove 501 is provided on the scraper 5 to match the limiting strip 102. The limiting strip 102 and the limiting groove 501 are used to further limit the scraper 5 and ensure the stability of the scraper 5 when it rises and falls.

[0029] In at least one embodiment, the racks 200 are configured in multiple sets and evenly spaced along the circumference of the base plate 2. By setting multiple sets of racks 200, the soil below the base plate 2 can be efficiently broken up, thereby improving drilling efficiency.

[0030] In at least one embodiment, the spiral grooves 403 are arranged in multiple sets at uniform intervals along the circumference of the groove 402. By setting multiple sets of spiral grooves 403, the stability of the insertion rod 4 can be achieved, ensuring the stability of the insertion rod 4 when it rotates.

[0031] In at least one embodiment, a mounting base 6 is fixedly provided on the top of the drill barrel 1. The mounting base 6 has a mounting groove, and the hydraulic cylinder 3 is located in the mounting groove. By placing the hydraulic cylinder 3 in the mounting base 6, it is convenient to connect and fix the drill rod of the rotary drilling rig to the drill barrel 1 through the mounting base 6.

[0032] During drilling operations, the operator connects and fixes the drill rod of the rotary drilling rig to the top of the drill barrel 1. Then, the drill rod drives the drill barrel 1 to descend for drilling. During the drilling process, the rack 200 on the bottom plate 2 of the drill barrel 1 breaks up the soil. The broken soil enters the receiving cavity 101 inside the drill barrel 1 through the through hole 201 on one side of the rack 200. When the drill barrel 1 descends to a certain depth, the receiving cavity 101 is filled with soil. Then, the operator activates the hydraulic cylinder 3, which drives the fixed rod 301 to rise via its output shaft. During the rise of the fixed rod 301, the protrusion 302 slides along the spiral groove 403 of the groove 402, thereby causing the insertion rod 4 to rotate a certain angle along the countersunk hole 202. As the insertion rod 4 rotates, it causes the baffle 401 to rotate along the sliding groove, ultimately causing the baffle... Plate 401 is rotated to align with through hole 201, thus blocking through hole 201 and preventing soil in receiving cavity 101 from falling back into the borehole through through hole 201 when drill barrel 1 is raised. This ensures complete cleaning of soil in receiving cavity 101. After the operator raises drill barrel 1 to the top of the borehole, the base plate 2 and drill barrel 1 can be released from fixation by disassembly mechanism. Then, the output shaft of hydraulic cylinder 3 drives the fixing rod 301 to extend, thereby driving the base plate 2 to descend. During the descent, the cleaning mechanism on fixing rod 301 can clean the soil in receiving cavity 101, improving cleaning efficiency. After cleaning, the operator retracts fixing rod 301 into receiving cavity 101 and connects and fixes base plate 2 and drill barrel 1 through disassembly mechanism before proceeding to the next round of drilling. The operation is convenient.
