Description

Technical Field

[0001] The invention relates to the technical field of mineral exploration, in particular to a sampling device for geological and mineral exploration. Background Art

[0002] Mineral exploration sampling refers to the collection of a certain number of samples from ore bodies, surrounding rocks and mine products according to certain specifications or requirements. Through processing, analysis, testing and identification, the quality of minerals, the physical and chemical properties of ores and surrounding rocks, the technical performance of ore processing, the technical conditions for mining of ore deposits, etc., is studied to provide data basis for ore deposit evaluation, reserve calculation and solution of problems related to geology, mining, beneficiation and comprehensive utilization of minerals.

[0003] The existing mineral sampling device uses a cylindrical drill bit to drill holes in the ore, and then takes out the stone pillars in the holes as samples. However, in order to maintain sufficient rigid support, the inner wall of the cylindrical drill bit needs to be set thicker, which will lead to low efficiency of the drill bit when drilling into the ore, and the thin-walled drill bit is easy to deform during use, which will lead to low efficiency of ore sampling. In addition, when the existing drill bit completes sampling, the core inside the borehole needs to be removed by first removing the drill bit, and then the core can be broken by a chisel before it can be taken out, which makes the sampling work time-consuming and laborious. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a sampling device for geological and mineral exploration.

The rotating hole is provided on the inner wall of the upper end of the U-shaped bracket. The upper end of the rotating cylinder is rotatably connected to the inside of the rotating hole. The upper end of the rotating cylinder is fixedly sleeved with a rotating ring. The upper end of the rotating cylinder is rotatably connected to the inside of the clamping ring.

[0006] Specifically, the driving assembly includes a motor, a threaded rod and a through hole. The motor is embedded in the inner wall of the upper end of the U-shaped bracket. The output end of the motor is fixedly connected to a gear plate, and a gear ring is meshed on the surface of the gear plate. The through hole is opened on the upper surface of the rotating cylinder. The lower end of the threaded rod is inserted into the through hole. The lower end of the threaded rod is fixedly connected to the center of the upper surface of the slider. A threaded barrel is threadedly connected on the surface of the threaded rod, and an L-shaped plate is fixedly connected to the outer wall of the threaded barrel. The lower end of the L-shaped plate is fixedly connected to the upper surface of the U-shaped bracket.

[0007] Specifically, the auxiliary component includes an inclined plate, which is fixedly connected to the inner wall of the U-shaped bracket, a rotating groove is opened at the lower end of the inclined plate, a fixed shaft is fixedly connected to the inner wall of the rotating groove, a rotating rod is rotatably connected to the surface of the fixed shaft, a counterweight is fixedly connected to the lower end of the rotating rod, and a vertical opening is opened on the side wall of the U-shaped bracket close to the inclined plate.

[0010] Specifically, the lower surface of the rotating drum and the lower surface of the U-shaped bracket are located on the same horizontal plane.

[0011] Specifically, the side wall of the counterweight block corresponds to the lowermost end of the rotating drum, and the counterweight block corresponds to the vertical opening.

[0012] Beneficial effects of the present invention: (1) The sampling device for geological and mineral exploration described in the present invention pushes the slider downward through the threaded rod, and when the slider moves downward, it drives the sampling drill tube to rotate and move downward, so that the sampling drill tube rotates and drills on the surface of the ore. The sampling drill tube is supported by the rotating drum, so that the contact position between the sampling drill tube and the ore is supported, thereby preventing the sampling drill tube with a thin wall from being deformed during drilling. In this way, the sampling drill tube with a thin wall can be used to speed up the sampling of the ore.

[0013] (2) The sampling device for geological and mineral exploration described in the present invention drives the counterweight block to move out of the vertical opening through the rotating rod, and then releases the rotating rod to allow the counterweight block to fall freely. The counterweight block hits the rotating drum, which drives the slider and the sampling drill barrel to squeeze the drilled core to break it. Then the motor is controlled to reverse and drive the sampling drill barrel to rise. The rock core is directly brought out of the borehole through the sampling drill barrel, which effectively speeds up the efficiency of the sampling work. BRIEF DESCRIPTION OF THE DRAWINGS

The two ends of the slider 29 are slidably connected inside the two slide grooves 210. When the slider 29 moves downward, it drives the sampling drill barrel 28 to rotate and move downward, so that the sampling drill barrel 28 rotates and drills on the surface of the ore. The sampling drill barrel 28 is supported by the rotating cylinder 21, so that the position where the sampling drill barrel 28 contacts the ore is supported, to prevent the sampling drill barrel 28 with a thin wall from being deformed during drilling. In this way, the thin-walled sampling drill barrel 28 can be used to speed up the sampling of the ore.

[0019] Specifically, the driving assembly 3 includes a motor 31, a threaded rod 34 and a through hole 35. The motor 31 is embedded in the inner wall of the upper end of the U-shaped bracket 1. The output end of the motor 31 is fixedly connected to a gear plate 32. A gear ring 33 is meshed on the surface of the gear plate 32.

When the slider 29 contacts the surface of the ore, the rotating rod 44 is pushed to rotate around the fixed axis 43, and the counterweight block 45 is driven by the rotating rod 44 to move out of the vertical opening 46. Then the rotating rod 44 is released to allow the counterweight block 45 to fall freely, and the counterweight block 45 hits the rotating drum 21. After the rotating drum 21 is hit, it drives the slider 29 and the sampling drill barrel 28 to squeeze the drilled core to break, and then the motor 31 is controlled to reverse and drive the sampling drill barrel 28 to rise, and the core is directly brought out of the borehole through the sampling drill barrel 28, effectively speeding up the efficiency of the sampling work.
