Description

Technical Field

[0001] This utility model relates to the field of fluorite ore sampling technology, and more specifically, to a sampling device for fluorite ore detection. Background Technology

[0002] The main mineral in low-grade fluorite ore, a polymetallic associated mineral of tungsten, molybdenum, tin, and bismuth, is fluorite (CaF2), accompanied by various metallic minerals such as tungsten (W), molybdenum (Mo), tin (Sn), and bismuth (Bi). Fluorite is an important chemical raw material, mainly used in metallurgy, glass, and ceramics industries. Tungsten, molybdenum, tin, and bismuth have important industrial applications; for example, tungsten is used in cemented carbide, molybdenum in steel alloys, and tin in solder. The tailings after mineral flotation can be used to produce building materials (such as bricks and cement) and soil conditioners, reducing the environmental impact of tailings discharge. During the mining and processing of fluorite ore, regular ore sampling and testing are necessary. Sampling and testing allow for precise analysis of the content and grade of minerals such as fluorite, tungsten, molybdenum, tin, and bismuth in the ore, providing data support for mineral resource reserve assessment. Simultaneously, the test results help determine the optimal beneficiation process, such as selecting appropriate flotation reagents and process parameters, thereby improving the recovery rate of fluorite and other valuable minerals. Testing the fluorite tailings after flotation can reveal valuable mineral components remaining in the tailings, providing a basis for the reprocessing or resource utilization of the tailings.

[0003] A search revealed that Chinese patent CN217403852U discloses an automatic sampling machine for fluorite ore detection. The machine transports stones via a conveyor belt, and then a sampling plate randomly samples the stones above the conveyor belt. The sampling plate is driven by a drive motor to rotate, thus achieving automatic sampling of stones. When the sampling plate rotates above the conveyor belt, it sweeps the raw ore on the conveyor belt into a collection box. The sampling time of the sampling plate can be designed and adjusted by controlling the speed of the drive motor.

[0004] However, according to the content disclosed in the aforementioned patent technology, although it can sweep the raw ore on the transmission belt into the collection box by rotating the sampling plate, each time it is swept in by the impact of the sampling plate, it is not only very easy to damage the sampling plate, baffle and other components, increasing the maintenance and replacement rate and increasing costs; moreover, the device is directly mounted on the top of the transmission belt, and once installed, it is not easy to disassemble or move, making it inconvenient to use.

[0005] Therefore, this application provides a sampling device for detecting fluorite ore to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems mentioned in the background art and to provide a sampling device for detecting fluorite ore.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A sampling device for fluorite ore detection includes a base plate with four casters at its bottom and multiple support rods on its top surface. A collection channel is located at the top of each support rod, and an intercepting plate is movably connected to the side wall of the collection channel. The intercepting plate samples fluorite ore from a conveyor belt and transports it to the collection channel. The collection channel has a sample inlet for feeding fluorite ore samples and a sample outlet for discharging fluorite ore samples. A sample storage container corresponding to the sample outlet is located on the top of the base plate.

[0009] Furthermore, the support rod includes a hydraulic telescopic rod connected to the center of the bottom surface of the collection channel and a limiting telescopic rod connected to the periphery of the collection channel.

[0010] Furthermore, the material collection channel includes a guide plate, a first baffle and a second baffle. The first baffle is lower than the second baffle. The first baffle is a square flat plate structure, and the second baffle is a combination structure of an integrally formed square flat plate and an arc plate. The two ends of the first baffle are respectively connected to the two ends of the second baffle to form a closed loop structure.

[0011] The guide plate is fixedly connected between the first baffle and the second baffle, and is provided with a funnel-shaped collection hopper, with the sample outlet located at the bottom of the collection hopper.

[0012] Furthermore, the guide plate is inclined, and the collecting hopper is located at the lowest end of the guide plate.

[0013] Furthermore, the side wall of the second baffle is provided with a mounting platform, the mounting platform is provided with a first through hole for the interceptor plate to move, and the extension direction of the interceptor plate and the extension direction of the first baffle plate have an angle.

[0014] The interceptor plate has a rack on the side away from the second baffle, the rack meshes with a gear, the mounting platform has a notch for the gear and rack to mesh and drive each other, the gear is rotatably connected to the mounting platform through a bearing, the gear shaft is connected to a motor, and the motor is fixedly connected to the mounting platform.

[0015] Furthermore, the base plate is connected to two first limiting blocks and one second limiting block. The two first limiting blocks are fixedly connected to the top surface of the base plate, and the second limiting block is movably embedded in the base plate. The sample storage container is placed between the two first limiting blocks and the second limiting block.

[0016] Furthermore, the base plate is provided with a limiting groove for the second limiting block to move up and down. A spring is provided in the limiting groove, and the two ends of the spring are respectively connected to the second limiting block and the base plate. The second limiting block has an inclined surface facing away from the two first limiting blocks, and at least part of the inclined surface is always in the limiting groove.

[0017] Furthermore, the base plate is provided with a second through hole communicating with the limiting groove. The second through hole extends out from the side of the base plate. A push rod is movably inserted into the second through hole. The push rod is adjustablely abutting against the inclined surface. After the push rod passes through the second through hole, it is connected to a push plate. The top surface of the push plate is not higher than the top surface of the base plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model uses a movable interceptor plate to sample low-grade fluorite ore or fluorite tailings from flotation, which is associated with tungsten, molybdenum, tin, and bismuth polymetallic minerals. The fluorite ore or tailings samples are collected via an inclined guide plate, an arc-shaped second baffle, and a funnel-shaped collection hopper. This system utilizes inertia to transport the sample from the sample inlet to the guide plate in the collection channel, and then allows it to fall from the collection hopper into the sample storage container. Furthermore, the second baffle, a combination of a square flat plate and an arc-shaped plate, acts as a buffer when the fluorite sample enters, effectively reducing equipment wear, lowering maintenance costs, and facilitating sample collection, thus improving sampling efficiency. After sampling, the motor is reversed to move the interceptor plate in the opposite direction until it leaves the conveyor belt. The device can then be moved directly to a convenient parking position, making it more convenient to use.

[0020] 2. This utility model, by setting two fixed first limiting blocks and one movable second limiting block, can automatically form a limiting fixation when the sample storage container is placed, ensuring the stability of the sample storage container; when it is necessary to remove the sample storage container, simply push the push rod with the push plate to squeeze the inclined surface of the second limiting block, thereby pressing the second limiting block back into the limiting groove, and the sample storage container can be removed, which is very convenient.

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] Example 1: See Figures 1-4 As shown, the solution of this embodiment provides a sampling device for fluorite ore detection, including a base plate 1. Four movable wheels 2 are installed at the bottom of the base plate 1. Two of the four movable wheels 2 can be set as universal wheels according to actual needs. Four support rods 3 are installed on the top surface of the base plate 1. One of them is a hydraulic telescopic rod 301 connected to the center of the bottom surface of the collection channel 4, which is mainly used to lift the collection channel 4 so that it can match the conveyor belt 15 of different heights. The other three are connected around the collection channel 4, which mainly play the role of supporting the entire collection channel 4. Conventional telescopic rods 302 with telescopic performance are used.

[0035] A collection channel 4 is installed at the top of multiple support rods 3. An intercepting plate 5 is movably connected to the side wall of the collection channel 4. The intercepting plate 5 samples the fluorite ore on the conveyor belt 15 and transports it to the collection channel 4. The collection channel 4 has a sample inlet 401 for feeding low-grade fluorite ore associated with tungsten, molybdenum, tin, and bismuth polymetallic minerals or fluorite tailings after flotation, and a sample outlet 406 for discharging fluorite ore samples. A sample storage container 6 corresponding to the sample outlet 406 is provided on the top of the bottom plate 1. The collection channel 4 includes a guide plate 402, a first baffle 403, and a second baffle 404. The first baffle 403 is lower than the second baffle 404. The first baffle 403 has a square flat plate structure. During the sampling process, the first baffle 403 moves to the bottom of the conveyor belt 15, and its extension direction is consistent with the extension direction of the conveyor belt 15.

[0036] The second baffle 404 is a combination structure of a square flat plate and an arc plate integrally formed, and the two ends of the first baffle 403 are respectively connected to the two ends of the second baffle 404 to form a closed loop structure. It mainly plays a protective role in the collection process of fluorite ore samples to prevent them from falling to the outside. The guide plate 402 is fixedly connected between the first baffle 403 and the second baffle 404, and is provided with a funnel-shaped collection hopper 405. The sample outlet 406 is set at the bottom of the collection hopper 405. The guide plate 402 is inclined, and the collection hopper 405 is located at the lowest end of the guide plate 402.

[0037] The second baffle 404 has a mounting platform 7 installed on its side wall. The mounting platform 7 has a first through hole 71 for the interceptor plate 5 to move, and the extension direction of the interceptor plate 5 and the extension direction of the first baffle 403 have an angle. The side of the interceptor plate 5 away from the second baffle 404 has a rack 501, which meshes with a gear 8. The mounting platform 7 has a notch 72 for the gear 8 and the rack 501 to mesh and drive each other. The gear 8 is rotatably connected to the mounting platform 7 through a bearing. The shaft of the gear 8 is connected to a motor 9, which is fixedly installed on the top surface of the mounting platform 7.

[0038] The working principle of this embodiment can be summarized as follows:

[0039] like Figure 1 and Figure 2 As shown, in the unsampled state, the interceptor plate 5 is moved to the end away from the collection channel 4. At this time, the entire device is moved to the side of the conveyor belt 15 by the moving wheels 2. The height of the collection channel 4 is adjusted by the hydraulic telescopic rod 301, and the first baffle 403 is moved to the bottom of the conveyor belt 15, with its extension direction consistent with the extension direction of the conveyor belt 15. After adjustment, the sample storage container 6 is placed on the base plate 1, and sampling can begin. First, the motor 9 is started. The motor 9 drives the gear 8 to rotate and meshes with the transmission interceptor plate 5 to move it, so that it is gradually inserted into the tungsten-molybdenum-tin-bismuth polymetallic associated low-grade fluorite ore or the fluorite tailings after flotation, such as... Figure 3 and Figure 4 As shown, some fluorite ore, under the interception action of the interceptor plate 5, is transported from the sample inlet 401 to the guide plate 402 of the collection channel 4 by inertia, and then leaks from the collection hopper 405 into the sample storage bucket 6. Since the second baffle 404 is a combination of a square flat plate and an arc-shaped plate, when low-grade fluorite ore associated with tungsten, molybdenum, tin, and bismuth polymetallic minerals or fluorite tailings samples after flotation enter, a buffer is formed at the arc-shaped plate, effectively reducing equipment wear, lowering maintenance costs, and facilitating the collection of fluorite ore samples, thus improving sampling efficiency. After sampling, the motor 9 is reversed to move the interceptor plate 5 in the opposite direction until it leaves the conveyor belt 15. Then, the device is moved directly to a convenient parking position, making it more convenient to use.

[0040] Example 2: See Figures 5-8 As shown, the difference between this embodiment and Embodiment 1 is that:

[0041] The base plate 1 is connected to two first limiting blocks 10 and one second limiting block 11. The two first limiting blocks 10 are fixedly connected to the top surface of the base plate 1, and the second limiting block 11 is movably embedded in the base plate 1. The base plate 1 is provided with a limiting groove 101 for the second limiting block 11 to move up and down. A spring 12 is provided in the limiting groove 101. The two ends of the spring 12 are respectively connected to the second limiting block 11 and the base plate 1. The second limiting block 11 has an inclined surface 1101 facing away from the two first limiting blocks 10, and at least part of the inclined surface 1101 is always in the limiting groove 101. The sample storage container 6 is placed between the two first limiting blocks 10 and the second limiting block 11.

[0042] The base plate 1 is provided with a second through hole 102 that is connected to the limiting groove 101. The second through hole 102 extends out from the side of the base plate 1. A push rod 13 is movably inserted into the second through hole 102. The push rod 13 is adjustablely abutted against the inclined surface 1101. After the push rod 13 passes through the second through hole 102, it is connected to a push plate 14. The top surface of the push plate 14 is not higher than the top surface of the base plate 1.

[0043] The working principle of this embodiment can be summarized as follows:

[0044] When the sample storage container 6 is pushed from one corner of the base plate 1 toward the two first limiting blocks 10, it first contacts the inclined surface 1101 of the second limiting block 11. The second limiting block 11 is gradually pressed down into the limiting groove 101, and the spring 12 is compressed, as... Figure 5 and Figure 8 As shown, when the sample storage container 6 is completely placed between the two first limiting blocks 10 and the second limiting block 11, under the elastic force of the spring 12, part of the second limiting block 11 extends out of the limiting groove 101, as shown. Figure 6 and Figure 7 As shown, the sample storage container 6 is fixed in place to prevent it from moving during sampling. After sampling is completed, the sample storage container 6 can be moved to a suitable position using the moving wheels 2, and then removed. The steps for removing the sample storage container 6 are as follows: First, push the push rod 13 through the push plate 14 to press it against the inclined surface 1101 of the second limiting block 11, thereby pressing the second limiting block 11 back into the limiting groove 101, and then the sample storage container 6 can be removed.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
