Description

Technical Field

[0001] This utility model relates to the field of geological exploration equipment technology, and in particular to an automatic soil removal and cleaning mechanism for soil drilling samplers. Background Technology

[0002] A soil drilling sampler is a tool or device specifically designed for collecting soil samples, widely used in agricultural research, geological exploration, environmental monitoring, and engineering construction. Its core function is to penetrate the surface soil layer through mechanical drilling to obtain soil samples at different depths for analysis of the soil's physical properties (such as texture, moisture content, and density), chemical properties (such as nutrient content, heavy metal content, and pH), or biological characteristics. An automatic soil removal and cleaning mechanism is a functional device integrated into soil drilling samplers, engineering drilling equipment, or agricultural machinery to automatically complete the removal of soil after sampling (soil removal) and the cleaning of equipment components.

[0003] The automatic soil removal and cleaning mechanism of the soil drilling sampler mainly consists of a power system (electric / hydraulic / pneumatic drive device), soil removal execution components (push rod, bulldozer plate or auger), cleaning components (rotary brush, high-pressure nozzle, scraper), control system (sensor, PLC and solenoid valve), and auxiliary support structure (guide rail bracket, sampling tube fixing seat). Its basic structure uses the power system to drive the soil removal execution components to push the soil out of the sampling tube, while the cleaning components use physical wiping or fluid flushing to remove residual soil. The control system coordinates the automatic operation of each component according to a preset sequence, and the auxiliary structure ensures the stability of the overall action, achieving efficient integration of soil removal and cleaning.

[0004] During the soil sampling process, the soil's stickiness or dryness can cause jamming and wear, leading to incomplete soil removal and failure to clean the soil from the core sampler in a timely manner, resulting in sample damage. A new design connects the telescopic outer rod (a) to the bottom limiting outer ring. When the telescopic outer rod (a) is pulled, the inner sliding plate reciprocates inside the bottom tray, allowing the telescopic outer rod (a) to slide up and down. The retractable rod (b) can retract into the telescopic outer rod (a), and the inner wall cleaning disc can rotate inside the retractable column (c). When the retractable column (c) bends, the inner wall cleaning disc can enter the core sampler. Through reciprocating motion, the inner wall cleaning disc cleans the residual soil inside the core sampler, thus achieving a cleaning effect. Therefore, an automatic soil removal and cleaning mechanism for soil drilling samplers is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic soil removal and cleaning mechanism for a soil drilling sampler, which aims to improve the problem of the inability to clean the residue inside the core drill bit in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] As a further description of the above technical solution:

[0011] The cleaning assembly includes a rotating block, the bottom of which is fixedly connected to the top of the shrinking column c. An inner wall cleaning disc is provided at the bottom of the shrinking column c. An inner rotating gear b is fixedly connected inside the inner wall cleaning disc. A gear a is fixedly connected to the bottom of the shrinking column c. The gear a meshes with the inner rotating gear b inside the inner rotating gear b.

[0012] As a further description of the above technical solution:

[0013] A motor is fixedly connected inside the inner protective shell, a sensing column is fixedly connected to the drive end of the motor, and a connecting column is slidably connected to the outside of the sensing column.

[0014] As a further description of the above technical solution:

[0015] The connecting post is slidably connected to a detachable retaining ring, and the bottom of the detachable retaining ring is fixedly connected to a retaining post a, and the bottom of the detachable retaining ring is fixedly connected to two retaining posts b.

[0016] As a further description of the above technical solution:

[0017] The connecting column is slidably connected to a fixing bolt inside, and a cap is fixedly connected to the outer side of the fixing bolt. A core-taking rotor is fixedly connected to the bottom of the cap.

[0019] The external sliding connection of the locking pin a is inside the fixing pin, and the external sliding connection of the locking pin b is inside the core-retrieving rotor.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the bottom of the telescopic outer rod a is fixed to the limiting outer ring.

[0022] 2. In this utility model, the sensing post is inserted into the interior of the connecting post, and then the fixing bolt is inserted into the interior of the connecting post for locking and fixing. Since the fixing bolt inside the connecting post will be thrown off when the motor drives the core-taking rotor to rotate, the locking post a at the bottom of the detachable locking ring is inserted into the interior of the core-taking rotor, and the locking post b at the bottom of the detachable locking ring is inserted into the top of the core-taking rotor for fixing. This makes it easy to remove the locking cap and fix one side of the fixing bolt. With the cooperation of the detachable locking ring structure, the problem of inconvenient disassembly of the core-taking rotor and the sensing post is solved. Attached Figure Description

[0031] Reference Figures 2 to 4The cleaning assembly includes a rotating block 17, which is a cylindrical metal block. The top of the rotating block 17 is fixedly connected to the bottom of the retractable column c18 via bolts. An inner wall cleaning disc 21 is located at the bottom of the retractable column c18. An inner rotating gear b20 is fixedly connected inside the inner wall cleaning disc 21. A gear a19 is fixedly connected to the bottom of the retractable column c18.

[0032] Working principle: The bottom of the pressing handle 2 is fixed to the inner protective shell 3. The pressing handle 2 has an anti-slip sleeve 1 to prevent the hand from slipping during operation. The inner protective shell 3 has a stable handle 4 on the outside, which provides a more traction point during operation. Since cleaning is required inside the core-retrieving rotor 30, a fixing plate 5 is fixed to the outside of the inner protective shell 3, and a rotating shaft 31 is fixed in the middle of the fixing plate 5. During reciprocating motion, the bottom tray 14 is subjected to the extension and retraction of the outer rod a9. The inner slide plate 12 is fixed outside the limiting outer ring 11. During the force process, the bottom tray 14 can... Rotation, the top of the telescopic outer rod a9 is fixed with an anti-detachment plate 10 to prevent the telescopic outer rod a9 from falling off directly during reciprocating motion, then the fixed curved plate 7 is attached to the outside of the base plate 6 and fixed with a fixing button 8 to prevent the telescopic outer rod a9 from falling off, and the centering button 13 is used to fix the inner sliding plate 12 to the outside of the bottom tray 14. Through reciprocating motion, the telescopic outer rod a9 and the anti-detachment plate 10 can slide up and down, and the retractable rod b15 can retract into the inside of the telescopic outer rod a9. By fixing the rotating column 16 at the bottom of the retractable rod b15, the rotating block 17 rotates. The movable column 16 can be bent externally because the bottom of the rotating block 17 is fixed with a retractable column c18. The bending of the rotating block 17 drives the retractable column c18, causing it to fold halfway into the core-retrieving rotor 30. The bottom of the retractable column c18 has a gear a19 and an internal gear b20 connected to one end of the inner wall cleaning disc 21, allowing the inner wall cleaning disc 21 to rotate under force. This reciprocating motion then cleans the inner wall cleaning disc 21 inside the core-retrieving rotor 30. Because the bottom of the motor 22 is fixed with a sensing column 23, the motor 2... The drive simultaneously rotates the connecting column 24 and the bottom of the core-retrieving head 30. The core is fixed by a fixing bolt 25 passing through the inside of the connecting column 24. Since direct fixing would cause the core-retrieving head 30 to wobble when rotating, a cap 26 is fixed on one side of the fixing bolt 25. The fixing bolt 25 is fixed by inserting the bottom locking post a28 of the detachable locking ring 27 on the outside of the connecting column 24. For a more secure fit, the two bottom locking posts b29 of the detachable locking ring 27 are inserted into the top of the core-retrieving head 30 for easy disassembly and installation.
