Description

Technical Field

[0001] This invention relates to the field of mine sampling, and more particularly to a sampling drill bit for a tracked vehicle used for sampling sand and gravel mines. Background Technology

[0002] Mine geological sampling refers to the collection of specific samples from ore bodies, surrounding rocks, and mine products according to certain specifications. This process, followed by analysis, testing, or identification, encompasses the entire process. Its purpose is to study mineral quality, the physical and chemical properties of ore and surrounding rocks, the technical performance of the ore, and mining conditions, providing data for deposit evaluation, reserve calculation, and related geological, mining, beneficiation, and comprehensive mineral utilization practices.

[0003] A sampling drill bit is a tool used to sample geological resources such as soil. It is widely used in fields such as geological exploration and environmental monitoring, especially in mining sampling. Sampling methods vary depending on the geological conditions of the mine. For sand and gravel mines, the geology is relatively loose and there is a lot of water vapor and dust. Based on this, a tracked sampling vehicle for sand and gravel mines was designed, which uses a multi-joint robotic arm to control the sampling drill bit for sampling.

[0004] In existing mine sampling processes, most samples are taken using sampling drills. For example, a mine geological environment monitoring device disclosed in Chinese patent CN214097445 U uses a controller to start a rotary motor, which drives a threaded rod to rotate. The threaded rod drives a movable block to move downwards, which in turn drives a slider to slide on the outer wall of the slider. The movable block then drives a connecting rod to move downwards. When the bottom of the rotating rod contacts the mine surface, the controller starts a sampling motor, which drives the rotating rod to rotate via an output shaft. The rotating rod then drives a spiral blade to rotate, and the rotating rod begins to drill a hole in the mine. The sand and gravel produced during drilling are then transported to the ground by the spiral blade. This device has a fixed and bulky structure, and its simple spiral blade structure makes it impossible to achieve sampling at specific depths, making it very inconvenient to use. Summary of the Invention

[0005] In view of the above problems, the present invention is proposed to provide solutions that overcome or at least partially solve the above problems.

[0006] According to one aspect of the present invention, a sampling drill bit for a tracked vehicle used for sampling sand and gravel mines is provided, comprising a drill rod, the drill rod including a drill rod sleeve, a sampling rod disposed inside the drill rod sleeve, the sampling rod being rotatably connected to the drill rod sleeve via a sampling bearing, the upper end of the sampling rod being drively connected to the output shaft of a sampling motor, the bottom of the sampling rod being provided with a spiral feeding blade for sampling and conveying sand and gravel, and a sand discharge port being provided in the middle of the drill rod sleeve, the sand discharge port being disposed above the spiral feeding blade.

At this time, the sand discharge port is located above the top opening of the sampling container. The sample is controlled by the operation of the sampling motor to enter the sampling container through the sand discharge port.

[0014] The sampling drill bit provided by this invention features a drill rod sleeve with a vibrator on the outside of the drill rod. The vibrator and the needle tip structure of the drill rod sleeve assist in the insertion of the drill rod. Simultaneously, an internal motor drives the spiral feeding blades to drill deeper. Waste samples are discharged through the sand discharge port, and the sample at the target depth is retained inside the front end of the drill rod sleeve. This enables sampling at a specific depth.

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] The terms "comprising" and "having," and any variations thereof, in the specification, embodiments, claims, and drawings of this invention are intended to cover non-exclusive inclusion, such as including a series of steps or units.

[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] A sampling drill bit for tracked vehicles used in sand and gravel mining, such as Figure 1 and Figure 2As shown, the system includes a drill rod 1, which includes a drill rod sleeve 11. A sampling rod 12 is provided inside the drill rod sleeve 11. The sampling rod 12 is rotatably connected to the drill rod sleeve 11 through a sampling bearing 14. The upper end of the sampling rod 12 is connected to the output shaft of the sampling motor 15. The bottom of the sampling rod 12 is provided with a spiral feeding blade for sampling and conveying sand and gravel. A sand discharge port 13 is opened in the middle of the drill rod sleeve 11, which is located above the spiral feeding blade.

[0022] In one possible implementation, the bottom of the drill pipe sleeve 11 has a needle-like structure, which facilitates insertion into the sand and gravel mine.

[0023] In one possible implementation, a connecting sleeve 16 is provided at the top of the drill pipe sleeve 11, and the sampling motor 15 is located inside the connecting sleeve 16.

[0024] In one possible implementation, a vibrator 3 is also provided on the outside of the connecting sleeve 16 to assist the drill pipe sleeve 11 in being inserted into the sand and gravel mine. The vibrator 3 is a waterproof vibration motor.

[0025] In one possible implementation, the drill rod 1 is pushed into the ore pile manually or by a robotic arm, the sampling motor 15 is turned on to drill, and after being inserted to a specified angle and depth, a specific depth and a specific number of ore samples are extracted.

[0026] In one possible implementation, the sampling rod 12 is driven by the sampling motor 15 and rotates in the drill rod sleeve 11. It is driven into the ore sand by manual or mechanical means. The ore sand is driven by the spiral feeding blades towards the manual or mechanical means and is discharged through the sand discharge port 13 of the drill rod sleeve 11. When the drill rod 1 reaches a specific depth, the sampling rod 12 stops rotating. The ore sand left by the spiral feeding blades at this moment is the sample. It is pulled out of the mine by manual or mechanical means. The sand discharge port 13 of the drill rod sleeve 11 discharges the sample left at a non-specific depth. Finally, the manual or mechanical means enter the sampling container 43 of the sampling box 4 and continue to rotate to perform sampling, thus realizing the sampling work.

[0027] In one possible implementation, such as Figure 3 As shown, the top of the drill rod 1 is provided with a drill rod quick-release seat 2. The upper end of the drill rod quick-release seat 2 is connected to the multi-joint robotic arm of the tracked vehicle, and the lower end of the drill rod quick-release seat 2 is connected to the connecting sleeve 16.

[0028] In one possible implementation, such as Figure 6 As shown, the drill pipe quick-assembly base 2 includes a fixing plate 21, which is fixedly connected to the free section of the multi-joint robotic arm of the tracked vehicle. A sliding connecting block 22 is provided below the fixing plate 21, and both sides of the fixing plate 21 and the sliding connecting block 22 are connected by side plates 23.

[0029] In one possible implementation, the connecting sleeve 16 slides through the sliding connecting block 22. The upper end of the connecting sleeve 16 has several indexing adjustment holes 17 arranged in a linear array on both sides. The sliding connecting block 22 has adjustment fixing holes 24 and fixing screw holes 25 arranged sequentially from top to bottom on both sides. The position of the drill rod 1 is constrained by the indexing pin 26 passing through the adjustment fixing holes 24 and the indexing adjustment holes 17 with the appropriate height. The fixing screw hole 25 is screwed with a tensioning bolt 27, and the inner end of the tensioning bolt 27 presses and fixes the connecting sleeve 16.

[0030] Furthermore, the sliding connecting block 22 constrains the connecting sleeve 16 to move back and forth and left and right, the indexing pin 26 constrains its up and down movement and rotation, and the tensioning bolt 27 locks the drill rod 1, thus ensuring both the gripping force and stability, while also making the structure lightweight and allowing for quick installation and disassembly.

[0031] In one possible implementation, such as Figure 4 and Figure 5 As shown, it also includes a sampling box 4, which is located on the top of the tracked vehicle. It includes a sample chamber 41, a sampling chamber 42 on the top of the sample chamber 41, and a sampling container 43 with a top opening inside the sample chamber 41. The sampling chamber 42 has an opening on the side near the multi-joint robotic arm. The drill rod 1 can be controlled by the multi-joint robotic arm to extend into the sampling chamber 42. At this time, the sand discharge port 13 is located above the top opening of the sampling container 43. The sampling motor 15 controls the sample to enter the sampling container 43 through the sand discharge port 13.

[0032] Furthermore, the sampling container 43 is connected to the sample chamber 41 via a pull-out structure, which facilitates the opening and closing of the sampling container 43.

[0033] In one possible implementation, the sampling box 4 ensures relative isolation of the overall outdoor environment, is waterproof, sandproof, and prevents tipping. At the same time, it can bind the samples taken by the sampling box RFID reader to the project, time, location, and implementer, so as to preserve the samples and retain the true state of the site.

[0034] It is worth noting that other components not specifically mentioned are all direct applications of existing technology and can be purchased on the market, and are not specifically described in this application.

[0035] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
