Description

Technical Field

[0001] This utility model relates to the field of mineral separation and sampling equipment technology, and in particular to a portable multi-parameter sampling device for mineral exploration. Background Technology

[0002] Multi-parameter analysis of minerals mainly involves the separation of mineral particles. Therefore, mineral sampling is necessary before conducting mineral analysis. Mineral sampling primarily utilizes screening equipment to classify mineral particles according to their size, enabling the laboratory to analyze minerals within different size ranges.

[0003] Currently, mineral separation and sampling devices are described in patent application number CN202011081690.X, entitled "A Mineral Separation and Sampling Device." This patent mainly includes a separation barrel and a drive device for rotating the separation barrel. The separation barrel has multiple perforated holes. The mineral particles to be separated are placed into the separation barrel, and then the separation barrel is connected to the drive device. The drive device drives the separation barrel to rotate, separating particles that do not meet the requirements and retaining the particles needed for sampling.

[0004] However, according to the sampling requirements of mining standards, mineral piles of different particle sizes actually need to be sampled separately according to different particle size ranges (coarse, medium, fine, etc.). The sampling device in the above-mentioned patent can only retain particles larger than the diameter of the perforated hole, and cannot divide the mineral pile into multiple particle size ranges (more than 2 particle size ranges) at one time according to the preset requirements, which makes the separation sampling operation more cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a portable multi-parameter sampling device for mineral exploration, which solves the problems of existing sampling devices being unable to meet the requirements of multiple particle size ranges in a single separation and the separation process being cumbersome.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a portable multi-parameter sampling device for mineral exploration, comprising a shell, a turntable rotatably disposed within the shell, and a separation bucket detachably connected to the turntable. The separation bucket has a split structure, including at least three separation slots arranged sequentially from top to bottom, and any two adjacent separation slots are detachably connected.

[0007] Each separation tank has an opening at the top, and the opening end of the separation tank is equipped with a plug-in interface. The plug-in buckle is used to plug into the separation tank at the installation position above. Each separation tank has multiple screening holes at the bottom, and the diameter of the screening holes in each separation tank decreases sequentially from top to bottom.

[0008] The principle of this utility model:

[0009] Based on the number of particle size ranges that need to be separated from the mineral pile, prepare an appropriate number of separation tanks. For example, if the mineral pile needs to be divided into four piles according to the particle size range, then select four separation tanks that are suitable for the four particle size ranges. The separation tanks are stacked in sequence according to the decreasing sieve aperture size. Since each separation tank has an opening at the top and the opening end of the separation tank is equipped with a plug-in interface, the plug-in buckle is used to plug into the separation tank at the upper installation position, which indicates that the minerals screened at the upper position can smoothly enter the separation tank at the lower position.

[0010] Meanwhile, each separation tank can be detachably connected to adjacent separation tanks by means of buckles, magnetic attraction, bolts, etc., or multiple separation tanks can be fixed by using other connection structures, and the mineral particles to be screened can be placed into the separation tank at the top installation position.

[0011] Multiple separation tanks form a separation barrel, which is then fixed to a turntable. The rotation of the turntable causes the separation barrel to rotate, which in turn drives the individual separation tanks to rotate. This rotation of the tanks allows for the sieving of minerals within their respective areas until only mineral particles meeting the required standards remain in each tank, thus completing the multi-stage separation of minerals in a single operation. The qualified minerals can then be stored in sealed bags or other containers.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This application improves the existing separation tank structure by setting the existing one-piece separation tank as a split structure, and the number of separation tanks and the size of the screening holes can be selected. This allows the separation tank of this application to separate mineral particles of multiple particle size ranges at one time, reducing the difficulty of screening and sampling and improving sampling efficiency.

[0014] Furthermore, it also includes at least one locking assembly, which includes a mounting rod and a locking block on the mounting rod.

[0015] Each separation slot has an outwardly extending mounting plate at its upper part. The mounting plate has at least one through hole, the same number as the number of locking components. The mounting rod passes through multiple through holes and is inserted into each through hole.

[0016] The mounting rod is detachably connected to the turntable, and each separation groove is fixed between the turntable and the locking block by the mounting rod.

[0017] Furthermore, the turntable is located at the bottom of the outer casing, and the separation bucket is located above the turntable and is detachably connected to the turntable;

[0018] The separation slot at the top of the installation position is equipped with a detachable cover plate, while the separation slot at the bottom of the installation position is connected to the turntable.

[0019] Furthermore, a drive shaft is provided at the bottom of the turntable. The drive shaft passes through the bottom of the housing and is rotatably connected to the side wall of the housing. The drive shaft is coaxially arranged with the drive motor fixed outside the housing.

[0020] Furthermore, the upper surface of the turntable is provided with a downward-facing annular guide slope.

[0021] Furthermore, the bottom of the outer shell is provided with a frustum-shaped guide platform, the drive shaft passes through the guide platform, and the projection of the lower end face of the turntable covers the projection of the upper end face of the guide platform.

[0022] Furthermore, the lower part of the outer casing is provided with a discharge pipe that cooperates with the guide platform.

[0023] Furthermore, it also includes an auxiliary cleaning component, which includes at least one cleaning brush that fits against the inner wall of the housing and extends along the length of the housing, and the cleaning brush is fixedly connected to the turntable. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] like Figure 1 , 2As shown, a portable multi-parameter sampling device for mineral exploration includes a housing 100, which is a cylindrical structure with an open top. Multiple support pillars 110 are located below the housing 100, supporting the housing 100. A turntable 140 is rotatably disposed inside the housing 100, near the bottom of the housing 100. A drive shaft 130 is located at the bottom of the turntable 140, passing through the bottom of the housing 100 and rotatably connected to the side wall of the housing 100. The drive shaft 130 is coaxially arranged with a drive motor 120 fixed outside the housing 100. The drive shaft 130 and the housing 100 are rotatably connected via bearings. The drive motor 120 can be a conventional motor or an electrically controlled stepper motor, servo motor, etc. When the drive motor 120 rotates, it drives the turntable 140 to rotate, causing the separation container 200 mounted on the turntable 140 to rotate with it.

[0029] This application improves the overall structure of the separation tank 200, specifically, as follows: Figure 1 , 2 As shown, the separation tank 200 has a split structure, including at least three separation slots 210 arranged sequentially from top to bottom, and any two adjacent separation slots 210 can be detachably connected. Each separation slot 210 can be detachably connected to adjacent separation slots 210 by means of buckles, magnetic attraction, bolts, etc., or multiple separation slots 210 can be fixed by other connection structures.

[0030] Meanwhile, each separation tank 210 has an opening at its upper end, and the opening end of the separation tank 210 is provided with a plug-in interface 215. The plug-in interface is used to connect with the separation tank 210 at the upper installation position. Each separation tank 210 has multiple screening holes 211 at its bottom. The setting of the plug-in interface 215 indicates that the minerals screened out in the upper separation tank 210 can smoothly enter the lower separation tank 210.

[0031] Since the separation tank 200 needs to screen minerals of multiple particle size ranges at once, it is also necessary to ensure that the aperture of the sieve holes 211 in each separation tank 210 decreases sequentially from top to bottom. During use, a suitable number of separation tanks 210 are prepared according to the number of particle size ranges to be separated from the mineral pile. For example, if the mineral pile needs to be divided into four piles according to particle size ranges, four separation tanks 210 suitable for the four particle size ranges are selected, and each separation tank 210 is overlapped sequentially in a manner where the aperture of the sieve holes 211 decreases sequentially. The minerals then pass through each separation tank 210 sequentially from top to bottom, and the required mineral particles are intercepted within each separation tank 210.

[0032] To facilitate the fixing of separation grooves 210 of varying numbers and compositions to the turntable 140, this application also includes a locking assembly, with at least one locking assembly. In this application, for example... Figure 1 , 2As shown, two locking assemblies are provided. Each locking assembly includes a mounting rod 310 and a locking block 320 on the mounting rod 310. The two mounting rods 310 are located on the left and right sides of the separation tank 200, respectively. Each mounting rod 310 has a threaded section in its upper middle part. The locking block 320 is threadedly connected to the upper middle part of the mounting rod 310. The lower end of the mounting rod 310 can be set as a non-circular block structure such as a square block. An insertion hole is provided on the turntable 140, and the lower end of the mounting rod 310 is inserted into the insertion hole on the turntable 140. Alternatively, a threaded section is provided at the lower end of the mounting rod 310, and the lower end of the mounting rod 310 is threadedly connected to the insertion hole, which can realize the detachable connection between the mounting rod 310 and the turntable 140. In this case, it is only necessary to fix each separation groove 210 to the mounting rod 310 to realize the detachable connection between the separation tank 200 as a whole and the turntable 140.

[0033] To facilitate the connection between each separation groove 210 and the mounting rod 310, this application provides an outwardly extending mounting plate 213 at the upper part of each separation groove 210. Each mounting plate 213 has two through holes 214, located on opposite sides of the mounting plate 213. Multiple mounting plates 213 are spaced apart from top to bottom on multiple separation grooves 210, and the multiple through holes 214 can be opposite each other, so that the mounting rod 310 passes through the multiple through holes 214 and is inserted into each through hole 214. In use, the multiple separation grooves 210 that meet the requirements are first set up sequentially from top to bottom, and then the multiple separation grooves 210 are "connected" using two mounting rods 310. After the mounting rods 310 are connected to the turntable 140, the locking block 320 is moved to fix each separation groove 210 between the turntable 140 and the locking block 320 through the mounting rods 310, thus completing the assembly of the entire separation barrel 200 and the turntable 140.

[0034] During use, to better position each separation tank 210, this application defines the structure of the separation tanks 210 located at the uppermost and lowermost installation positions. Specifically, as follows: Figure 1 , 2 As shown, a socket 212 is provided at the bottom of the separation tank 210 located at the lowest installation position. The socket 212 is engaged with the plug 141 on the turntable 140 to facilitate the positioning of the separation tank 210. Of course, this separation tank 210 is the separation tank 210 with the smallest aperture of the screening hole 211. This separation tank 210 is used to assist in installation. During use, the mineral particles retained by this separation tank 210 are non-target minerals.

[0035] To prevent material from flying out of the uppermost separation tank 210, this application provides a detachable cover plate 220 for the uppermost installation position of the separation tank 210. The cover plate 220 can be locked to the separation tank 210 by the cooperation of the mounting rod 310 and the locking block 320. Specifically, as shown... Figure 1 ,2 As shown, a pressure rod 330 is provided below the locking block 320. The pressure rod 330 is located above the cover plate 220. When the locking block 320 moves downward to press each separation groove 210, the pressure rod 330 can press the cover plate 220 and the uppermost separation groove 210 together.

[0036] This application improves the structure of the separation tank 200 in the prior art by setting the existing one-piece separation tank 200 as a split structure, and the number of each separation tank 210 and the size of the sieve hole 211 can be selected, so that the separation tank 200 of this application can separate mineral particles of multiple particle size ranges at one time, reducing the difficulty of sieving and sampling and improving the sampling efficiency.

[0037] To facilitate the accumulation of waste material (mineral particles that do not need to be collected) discharged from the separation tank 210 on the surface of the turntable 140, this application provides a downward-sloping annular guide ramp on the upper surface of the turntable 140. For example... Figure 1 , 2 As shown, the turntable 140 with this structure, in conjunction with its rotation setting, can effectively prevent the accumulation of materials on the turntable 140 and allow them to fall to the bottom of the outer casing 100 as much as possible.

[0038] To facilitate the smooth discharge of material from the bottom of the outer casing 100, this application provides a frustum-shaped guide platform 160 at the bottom of the outer casing 100. A drive shaft 130 passes through the guide platform 160, and the projection of the lower end face of the turntable 140 overlaps the projection of the upper end face of the guide platform 160. A discharge pipe 150, which mates with the guide platform 160, is provided at the lower part of the outer casing 100. Figure 1 , 2 As shown, the bottom of the guide platform 160 of this application has an elliptical structure, which indicates that the bottom of the outer shell 100 has a lowest position. The unloading pipe 150 is provided at this position. The end of the unloading pipe 150 can be provided with a pipe cap 151 to facilitate the discharge of waste material from the outer shell 100.

[0039] Since the separation tank 210, located at the lowest installation position, is fixed in position and has the smallest sieve hole 211, and the waste material leaving the separation tank 210 does not need to be collected, multiple sieve holes 211 are also provided on the side wall of the separation tank 210 to facilitate sieving of the material in the separation tank 210. This indicates that the separation tank 210 is equivalent to a sieve screen cylinder structure. Therefore, the waste particles leaving the separation tank 210 may adhere to the inner wall of the outer casing 100 under centrifugal force. To clean the waste material adhering to the inner wall of the outer casing 100, this application also includes an auxiliary cleaning component, which includes at least one cleaning brush 170. Figure 1 , 2As shown, this application includes a cleaning brush 170, which has a strip-shaped structure. The brush portion of the cleaning brush 170 is attached to the inner wall of the outer casing 100, and the cleaning brush 170 extends along the length of the outer casing 100. Simultaneously, the cleaning brush 170 is fixedly connected to the turntable 140 via a fixing rod 171. Rotation of the turntable 140 drives the cleaning brush 170 to rotate, and the rotation of the cleaning brush 170 removes waste material adhering to the inner wall of the outer casing 100. Most of the removed waste material will be discharged through the discharge pipe 150 for processing.
