[0002] As a non-metallic raw material with strategic significance, fluorite is widely used and can be divided into three categories according to its grade and use: acid-grade fluorite for the chemical industry, with a fluorite mass fraction greater than 97%; followed by smelting-grade fluorite for steelmaking and electrolytic aluminum, with a fluorite mass fraction of 65%-85%; and ceramic-grade fluorite for making glass and ceramics in the building materials industry, with a fluorite mass fraction of 85%-95%.

[0003] At present, before mining smelting-grade fluorite, it is necessary to use a sampling device to sample and detect fluorite at different depths in this area, so as to obtain information on the quality of fluorite at different depths in this area;

[0004] However, for the existing sampling devices currently, when sampling fluorite at a specific depth, the fluorite above this depth is likely to be doped with the fluorite at this depth, resulting in mixed samples. After sampling, when detecting the quality of the sampled fluorite, the quality of the fluorite at this depth cannot be accurately obtained. In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0005] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a sampling device for smelting-grade fluorite ore that can overcome or at least partially solve the above problems.

A first gear is fixedly connected to the rotating sleeve. A motor is fixedly installed on the sampling tank. The output end of the motor is fixedly connected to a second gear. The second gear is meshed with the first gear.

[0010] In order to drive the lifting plate to rise or fall, preferably, a cylinder is fixedly connected to the sampling tank. The lifting plate is fixedly connected to the output end of the cylinder.

[0011] In order to prevent fluorite ore from remaining on the sealing plug during discharging, thus reducing the waste of fluorite ore, preferably, the upper end of the sealing plug is tapered.

[0012] Preferably, a mounting hole is formed on the support frame. A pin is arranged on the support frame. The pin is used in cooperation with the mounting hole.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] In the utility model, through the arrangement of the sealing plug, when the sampling tank is used to sample fluorite at a specific depth, it can prevent fluorite at other depths from entering the sampling tank through the feeding and discharging pipe and mixing with the fluorite at this depth, which is beneficial to the subsequent detection of the sampled fluorite ore. And when the sampling tank removes the fluorite, through the sealing plug that blocks the feeding and discharging pipe, it can prevent the fluorite sampled into the sampling tank from leaking through the feeding and discharging pipe, thus ensuring the sampling efficiency.

Detailed Embodiment

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0020] Embodiment 1:

[0021] Referring to Figure 1 、 Figure 2 、 Figure 3 a sampling device for metallurgical-grade fluorite ore, including a support frame 1, further including: a sampling tank 2 lift-connected to the support frame 1, wherein a feeding and discharging pipe 201 is fixedly communicated with the bottom of the sampling tank 2; a lifting plate 402 lift-connected to the sampling tank 2, wherein a rotating shaft 3 is rotatably connected to the lifting plate 402, and a sealing plug 4 is fixedly connected to one end of the rotating shaft 3 passing through the sampling tank 2, and the sealing plug 4 is slidably connected in the feeding and discharging pipe 201; a spiral propelling piece 301 fixedly connected to one end of the rotating shaft 3 passing through the sampling tank 2 and below the sealing plug 4.

[0022] A hydraulic telescopic rod 202 is fixedly connected to the support frame 1, a connecting seat 203 is fixedly connected to the sampling tank 2, and the connecting seat 203 is fixedly connected to the output end of the hydraulic telescopic rod 202.

[0023] A rotating sleeve 302 is rotatably connected to the sampling tank 2, a slider 404 is fixedly connected to the inner wall of the rotating sleeve 302, a guiding groove 403 is formed on the outer wall of the rotating shaft 3, the slider 404 is slidably connected in the guiding groove 403, a first gear 303 is fixedly connected to the rotating sleeve 302, a motor 305 is fixedly installed on the sampling tank 2, a second gear 304 is fixedly connected to the output end of the motor 305, and the second gear 304 is meshed with the first gear 303.

[0024] A cylinder 401 is fixedly connected to the sampling tank 2, and the lifting plate 402 is fixedly connected to the output end of the cylinder 401.

[0025] During use, start the hydraulic telescopic rod 202. The hydraulic telescopic rod 202 pushes the connecting seat 203 to drive the sampling tank 2 to move downward, thereby inserting the sampling tank 2 into the fluorite ore. When the sampling tank 2 moves to the depth where sampling is required, start the cylinder 401. The cylinder 401 drives the lifting plate 402 to move upward. At the same time, when the lifting plate 402 moves upward, it can drive the rotating shaft 3 to drive the sealing plug 4 and the spiral propeller 301 to move upward synchronously until the sealing plug 4 is separated from the inlet and outlet pipe 201, thus opening the inlet and outlet pipe 201. At this time, the spiral propeller 301 is located in the inlet and outlet pipe 201. Then start the motor 305. The motor 305 drives the rotating sleeve 302 to rotate through the meshing connection of the second gear 304 and the first gear 303. At the same time, the rotating sleeve 302 drives the rotating shaft 3 to drive the spiral propeller 301 to rotate. Thus, when the spiral propeller 301 rotates, it can push the fluorite at this depth into the sampling tank 2. When the sampling is completed, drive the sealing plug 4 to move downward through the cylinder 401, so that the sealing plug 4 is inserted into the inlet and outlet pipe 201, thereby blocking the inlet and outlet pipe 201 and preventing the fluorite sampled into the sampling tank 2 from leaking through the inlet and outlet pipe 201 when the sampling tank 2 is removed from the fluorite ore, thus ensuring the sampling efficiency.

[0026] Through the setting of the sealing plug 4, when sampling the fluorite at a specific depth using the sampling tank 2, it can prevent the fluorite at other depths from entering the sampling tank 2 through the inlet and outlet pipe 201 and being mixed with the fluorite at this depth, which is conducive to subsequent detection of the sampled fluorite.

[0027] When it is necessary to take out the fluorite ore in the sampling tank 2, drive the rotating shaft 3 to drive the sealing plug 4 and the spiral propeller 301 to move upward synchronously through the cylinder 401 until the sealing plug 4 is separated from the inlet and outlet pipe 201, thus opening the inlet and outlet pipe 201. At this time, the fluorite can be discharged from the sampling tank 2 through the inlet and outlet pipe 201;

[0028] At the same time, when the sealing plug 4 is separated from the inlet and outlet pipe 201, at this time, the spiral propeller 301 retracts into the inlet and outlet pipe 201. Then start the motor 305. The motor 305 drives the rotating sleeve 302 to rotate through the meshing connection of the second gear 304 and the first gear 303. At the same time, the rotating sleeve 302 drives the rotating shaft 3 to drive the spiral propeller 301 to rotate. Thus, when the spiral propeller 301 rotates, it can push the fluorite out of the sampling tank 2 at a uniform speed, avoiding blockage of the inlet and outlet pipe 201.

[0029] Embodiment 2:

[0030] Refer to Figure 1 For the sampling device of metallurgical-grade fluorite ore, it is basically the same as Embodiment 1. Further, the upper end of the sealing plug 4 is conically arranged.

[0031] When the metallurgical-grade fluorite in the sampling tank 2 is taken out through the feeding and discharging pipe 201, through the sealing plug 4 with a conical upper end (as Figure 1 shown), it is possible to avoid the fluorite remaining on the sealing plug 4, thereby reducing the waste of fluorite.

[0032] Embodiment 3:

[0033] Refer to Figure 1 、 Figure 3 , the metallurgical-grade fluorite ore sampling device is basically the same as that in Embodiment 1. Further, an installation hole is provided on the support frame 1, and a pin 101 is provided on the support frame 1, and the pin 101 is used in cooperation with the installation hole.

[0034] When using this sampling device to sample metallurgical-grade fluorite, first move this sampling device to the sampling location, and then insert the pin 101 through the installation hole into the soil to fix this sampling device, so as to improve the stability of this sampling device.

[0035] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
