Description

Technical Field

[0001] This invention relates to the field of mine sampling, and more particularly to a tracked vehicle 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] 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] However, due to the excessive moisture, dust, and fog in sand and gravel mines, the joints of robotic arms or external vibration motors are prone to water and fog ingress, which affects motor performance and lifespan. Similarly, if the drive unit of a tracked vehicle is exposed to air, the drive motor and bearings are prone to water and fog ingress, which also affects their performance and lifespan. Moreover, because the geology of sand and gravel mines is relatively loose, fine sand can easily enter the tracks during movement and then into the track drive mechanism, causing accelerated wear of the track drive mechanism and affecting the performance and lifespan of the tracked vehicle. In addition, how to achieve sampling and setting out at specific depths more conveniently is also an urgent problem to be solved. Summary of the Invention

[0020] 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.

[0021] 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.

[0022] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] A tracked vehicle for sampling in sand and gravel mines, such as Figure 1 As shown, it includes tracks 4 on both sides of the frame, a drive unit 3 inside the frame for driving the tracks 4, a robotic arm 2 on the top of the frame, and a sampling drill bit 1 on the end of the robotic arm 2 away from the frame. Sampling drill bit 1 is used for sampling and setting out at a specific depth; Robotic arm 2 is used to control the position of sampling drill bit 1; The drive unit 3 drives the tracks 4 to enable the tracked vehicle to move on the sand and gravel mine.

[0024] In one possible implementation, such as Figures 2-3 As shown, the sampling drill bit 11 includes a drill rod 11, the drill rod 11 includes a drill rod sleeve 111, a sampling rod 112 is provided inside the drill rod sleeve 111, the sampling rod 112 is rotatably connected to the drill rod sleeve 111 through a sampling bearing 114, the upper end of the sampling rod 112 is drivenly connected to the output shaft of the sampling motor 115, the bottom of the sampling rod 112 is provided with a spiral feeding blade for sampling and conveying sand and gravel, and a sand discharge port 113 is opened in the middle of the drill rod sleeve 111, the sand discharge port 113 is located above the spiral feeding blade; The bottom of drill pipe sleeve 111 adopts a needle-like structure, which makes it easy to insert into sand and gravel mines; The top of the drill pipe sleeve 111 is provided with a connecting sleeve 116, and the sampling motor 115 is located inside the connecting sleeve 116; In one possible implementation, a vibrator 13 is also provided on the outside of the connecting sleeve 116 to assist the drill pipe sleeve 111 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 11 is pushed into the ore pile manually or by a robotic arm, and the sampling motor 115 is turned on to drill. 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 112 is driven by the sampling motor 115 and rotates in the drill rod sleeve 111. 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 113 of the drill rod sleeve 111. When the drill rod 11 reaches a specific depth, the sampling rod 112 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 113 of the drill rod sleeve 111 discharges the sample left at a non-specific depth. Finally, the manual or mechanical means enter the sampling container 143 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 4 As shown, the drill rod 11 is provided with a drill rod quick-release seat 12 at the top. The upper end of the drill rod quick-release seat 12 is connected to the multi-joint robotic arm of the tracked vehicle, and the lower end of the drill rod quick-release seat 12 is connected to the connecting sleeve 116. The drill pipe quick-assembly base 12 includes a fixing plate 121, which is fixedly connected to the free section of the multi-joint robotic arm of the tracked vehicle. A sliding connecting block 122 is provided below the fixing plate 121, and both sides of the fixing plate 121 and the sliding connecting block 122 are connected by side plates 123. The connecting sleeve 116 slides through the sliding connecting block 122. Several indexing adjustment holes 117 are linearly arrayed on both sides of the upper end of the connecting sleeve 116. The sliding connecting block 122 has an adjustment fixing hole 124 and a fixing screw hole 125 sequentially opened from top to bottom on both sides. The position of the drill rod 11 is constrained by the indexing pin 126 passing through the adjustment fixing hole 124 and the indexing adjustment hole 117 with the appropriate height. A tensioning bolt 127 is screwed into the fixing screw hole 125. The inner end of the tensioning bolt 127 presses and fixes the connecting sleeve 116.

[0028] Furthermore, the sliding connecting block 122 constrains the connecting sleeve 116 to move back and forth and left and right, the indexing pin 126 constrains its up and down movement and rotation, and the tensioning bolt 127 locks the drill rod 11, which ensures both the gripping force and stability, and also makes the structure lightweight and allows for quick installation and disassembly.

[0029] In one possible implementation, such as Figure 5 and Figure 6 As shown, the sampling drill bit 1 also includes a sample placement box 14, which is located on the top of the tracked vehicle. It includes a sample chamber 141, a sample placement box 142 on the top of the sample chamber 141, and a sampling container 143 with a top opening inside the sample chamber 141. The sample placement box 142 has an opening on the side near the multi-joint robotic arm. The drill rod 11 can be controlled by the multi-joint robotic arm to extend into the sample placement box 142. At this time, the sand discharge port 113 is located above the top opening of the sampling container 143. The sampling motor 115 controls the sample to enter the sampling container 143 through the sand discharge port 113.

[0030] Furthermore, the sampling container 143 is connected to the sample chamber 141 via a pull-out structure, which facilitates the opening and closing of the sampling container 143.

[0031] In one possible implementation, the sampling box 14 ensures relative isolation from the overall outdoor environment, is waterproof, sandproof, and prevents tipping over. 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.

[0032] In one possible implementation, such as Figures 7-9As shown, the waterproof structure of the robotic arm 2 includes a joint waterproof ring 21 located at the joint of the robotic arm. The joint waterproof ring 21 includes an inner waterproof ring 211 and an outer waterproof ring 212, which are sealed and rotatably connected. The inner waterproof ring 211 is fitted on the outside of the robot arm motor, and the outer waterproof ring 212 is fitted on the outside of the corresponding joint of the robot arm; The inner waterproof ring 211 is provided with a first fastener 213 at one end near the outer waterproof ring 212, and the outer waterproof ring 212 is provided with a second fastener 214 at one end near the inner waterproof ring 211. Both the first fastener 213 and the second fastener 214 adopt a U-shaped structure, and the opening directions of the first fastener 213 and the second fastener 214 are opposite.

[0033] Furthermore, both the inner waterproof ring 211 and the outer waterproof ring 212 are made of salt spray resistant silicone material, which are respectively fitted onto both sides of the rotating joint of the robotic arm. The inner ring U-shaped groove is coated with sealing grease or water-absorbing material to ensure that the double ring structure rotates smoothly and is sealed and waterproof, thus increasing the waterproof and salt spray resistant performance of the robotic arm.

[0034] In one possible implementation, such as Figures 10-11 As shown, the waterproof structure of the robotic arm 2 also includes a waterproof vibration motor 22 mounted on the sampling drill bit, which includes a waterproof sealing housing 221, a vibration motor body 222 mounted on the waterproof sealing housing 221, and a vibration motor mounting bracket 223 mounted on the outside of the waterproof sealing housing 221. The vibration motor mounting bracket 223 adopts a U-shaped structure, which is clamped on the outside of the drill rod and fixed by bolts.

[0035] Furthermore, the waterproof vibration motor 22 is fixed on the sampling drill rod. When the drill rod is drilling downwards to take samples, the waterproof vibration motor 22 is turned on to make the drill rod vibrate. This structure has complete protection against rain, high salt spray and high dust environments in mining environments. It can transmit vibration and completely protect the motor from environmental interference that could cause it to fail.

[0036] In one possible implementation, such as Figures 12-15 As shown, the drive device 3 includes a drive shaft 31, a drive shaft mounting plate 32 and a sealing housing 33 are sleeved on the drive shaft 31, the drive shaft mounting plate 32 is fixedly connected to the sealing housing 33, and a main bearing 34 and a secondary bearing 35 are provided inside the sealing housing 33.

The sealed box 33 includes a sealed box bottom plate 331 and a sealed box body 332 on its outer side. The sealed box bottom plate 331 is fixedly connected to the drive shaft mounting plate 32. The main bearing 34 is sealed and fastened at the center of the bottom plate 331 of the sealing box, and the auxiliary bearing 35 is sealed and fastened at the center of the top plate of the main body 332 of the sealing box. The drive unit has two waterproof structures, which are respectively located on both sides of one end of the tracked vehicle frame 36. The drive shaft mounting plate 32 is sealed to the outer wall of the tracked vehicle frame 36, and the drive shaft 31 passes through the outer wall of the tracked vehicle frame 36.

[0037] In one possible implementation, two tracked vehicle drive motors 37 are symmetrically arranged inside the tracked vehicle frame 36, and the output shaft of the tracked vehicle drive motor 37 is connected to the drive shaft 31 on its corresponding side. The sealed housing 33 is located on the side of the drive shaft mounting plate 32 away from the tracked vehicle frame 36, and the end of the drive shaft 31 away from the tracked vehicle frame 36 is connected to the track drive wheel.

[0038] Furthermore, the tracked vehicle frame 36 adopts a box structure, and the connection between the box structure and other components adopts a sealed structure.

The sand discharge port 461 is equipped with a sand discharge shovel 462, which is used to shovel out the mineral sand adhering to the track from the sand discharge port when the tracked vehicle moves forward or backward. The sand-draining shovel 462 has a structure on both sides that gradually decreases in width from the inside to the outside. Furthermore, when a tracked vehicle travels through ore, the ore will enter the track drive mechanism. By using this structure to clamp the track on both sides, very little ore can enter the track structure. At the same time, the anti-sand shovel of this structure can scoop out the ore that has entered the track from the sand discharge port when the tracked vehicle moves forward or backward, ensuring the normal operation of the tracked vehicle in the mine.

[0040] To further clarify, this track is only intended to reduce the amount of fine sand entering the track drive system and to scrape out as much fine sand as possible from inside the track; it cannot provide complete sand protection.

[0041] The outer side of the track 45 is provided with two rows of symmetrical protrusions 451. The protrusions 451 are equidistantly arranged along the outer surface of the track 45.
