Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for limestone mining. Background Art

[0002] The main component of limestone is calcium carbonate. Lime and limestone are raw materials used in large quantities in building materials and industry. Limestone can be directly processed into stone and burned into quicklime. Quicklime absorbs moisture or adds water to become slaked lime. The main component of slaked lime is calcium hydroxide. Slaked lime is formulated into lime slurry, lime paste, etc., and is used as a coating material and brick and tile adhesive.

[0003] With the continuous development of mining technology, the global demand for limestone raw materials is increasing, making the ore mining industry prosperous. Ore mining will inevitably use sampling devices, and the mining plan will be decided after the samples are identified.

[0004] The Chinese patent with the existing patent application number of 202023010887.2 discloses a rapid ore sampling device, which relates to the technical field of sampling devices, including a carrier plate, electric telescopic rods are fixed at the four corners of the bottom of the carrier plate, and the bottom ends of the four electric telescopic rods are welded with a trolley, and the bottom of the trolley is welded with a shock-absorbing rod near the four corners, and a sliding plate is installed at the top center of the carrier plate. The utility model is convenient for sampling ores of different heights by moving the electric telescopic rod installed on the top of the trolley up and down, so as to change the height of the carrier plate, and the ore of different heights is sampled. The carrier is pushed to reciprocate on the top of the sliding plate by the hydraulic rod, so that the user can control the drilling depth of the drill bit. A sampling port is opened in the drill bit, and the sampling port is connected to the sampling slot. Ore debris of different depths is squeezed into the sampling tube in the sampling slot through the sampling port. The sampling tube is light and easy to transport. In one sampling, the ore components of different depths can be measured, which greatly reduces the time consumption and increases the efficiency of sampling.

[0005] However, the sampling device still has certain limitations in actual use. For example, it can only perform ore sampling operations at a height, which is not conducive to the implementation of multiple sampling operations. At the same time, the surface of the sampled ore is mostly irregular, and some are located above the device, and the drill bit cannot sample it. During further sampling, there is a lot of dust, which easily blocks the sampling area, making it inconvenient for the sampling personnel to observe the sampling position, which is not conducive to the sampling operation.

[0024] The sampling assembly 3 includes a mounting plate 301, on which a threaded slider 302 and a sleeve slider 303 are fixedly mounted at the bottom of the two side surfaces of the mounting plate 301, respectively. The threaded slider 302 is threadedly sleeved on the No. 2 transmission screw 106. A rotating groove is opened in the middle of the front side of the mounting plate 301, and a rotating shaft 304 is rotatably mounted on the top of the rotating groove. A rotating plate 305 is fixedly sleeved on the rotating shaft 304. One end of the rotating shaft 304 extends to the outside of one side surface of the mounting plate 301, and a driven gear 311 is fixedly sleeved on the extended end of the rotating shaft 304. An adjusting motor 309 is fixedly embedded in the middle of one side surface of the mounting plate 301 close to the sleeve slider 303, and a driving gear 310 is fixedly sleeved on one end of the output shaft of the adjusting motor 309, and the top of the driving gear 310 is meshedly connected with the bottom wall of the driven gear 311.

[0025] In this embodiment, a rotating motor 306 is fixedly installed on the back of the rotating plate 305, one end of the output shaft of the rotating motor 306 passes through the front of the rotating plate 305 and is fixedly installed with a rotating rod 307, and a sampling drill bit 308 is fixedly installed on the end of the rotating rod 307 away from the rotating plate 305. The sampling drill bit 308 is composed of a circular steel pipe and a drill bit. A sampling groove is opened near the center of the circular steel pipe, a sampling tube is embedded in the sampling groove, and a sampling port is opened near the center of the drill bit.

Since the threaded slider 302 is fixedly connected to a side of the mounting plate 301, and the sampling drill bit 308 is arranged in front of the rotating plate 305 rotatably installed in the middle of the front of the mounting plate 301, the lifting of the threaded slider 302 can drive the mounting plate 301 to rise and fall, and the lifting of the mounting plate 301 can drive the sampling drill bit 308 to rise and fall, so that the ores at different heights can be sampled. At the same time, since the ore surface is mostly irregular, and the sampling position of some ores is located above the device, it is necessary to adjust the direction of the sampling drill bit 308 to make the drill bit of the sampling drill bit 308 face the sampling surface. Specifically, first start the rotating motor 3 06. The driving gear 310 can be driven to rotate by rotating the motor 306. The rotation of the driving gear 310 can drive the driven gear 311 meshing with it to rotate. The rotation of the driven gear 311 can drive the rotating shaft 304 to rotate. Since the top of the rotating plate 305 is fixedly sleeved on the rotating shaft 304, the rotation of the rotating shaft 304 can drive the rotating plate 305 to rotate. The rotation of the rotating plate 305 will drive the rotating motor 306 to rotate. The rotation of the rotating motor 306 will drive the rotating rod 307 and the sampling drill bit 308 fixedly installed at the other end of the rotating rod 307 to rotate, thereby changing the direction of the sampling drill bit 308, thereby facilitating the sampling drill bit 308 to sample ores on different inclined surfaces and at the top of the device. When the sampling drill bit 308 is drilling and sampling, the water in the water tank 202 can be sprayed out through the water spray head 203, thereby playing a certain role in dust reduction.
