Description

Technical Field

[0001] This utility model belongs to the field of mineral powder sampling technology, specifically, it relates to a fine-particle mineral powder sampling device. Background Technology

[0002] Currently, the industry primarily employs two methods for sampling fine-grained mineral powder: manual sampling and automated sampling. Manual sampling mainly involves inserting a traditional sampling probe into the mineral powder. This method requires manual pressing of the probe into the powder, but the compact nature of the powder often results in insufficient insertion depth, compromising sample representativeness. Furthermore, it is labor-intensive and inefficient. Additionally, to prevent cross-contamination of samples, the sampling probe typically needs cleaning after sampling. Currently, cleaning is mainly done by wiping with a towel, which is ineffective and can contaminate subsequent samples. Automated sampling utilizes automated control equipment to grasp and transfer samples. However, this method involves higher investment costs, more frequent and complex maintenance, and is limited to fixed locations, resulting in poor flexibility. Due to investment and site constraints, its application in the mining industry is not widespread. Summary of the Invention

[0003] In order to overcome the problems existing in the background technology, this utility model provides a fine-particle mineral powder sampling device, which can effectively reduce the sampling difficulty, is easy to clean, reduces the risk of sample contamination, and has the characteristics of flexible use and convenient mobility, making it more suitable for sampling operations in mining areas.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: The fine-particle mineral powder sampling device includes a sampling probe, a connector, a sample lifting rod, and an electric drill. The sampling probe is a hollow tubular structure with a connecting plate A at its top and a discharge pipe at its upper part. A cleaning pipe is provided between the connecting plate A and the discharge pipe, and the cleaning pipe communicates with the inner cavity of the sampling probe. The connector is connected to the connecting plate A. The sample lifting rod is inserted into the sampling probe, with its upper end protruding from the connector.

[0010] Preferably, the discharge pipe is inclined downwards.

[0011] Preferably, a receiving bucket is provided below the discharge pipe.

[0020] like Figure 1-5 As shown, the fine-particle mineral powder sampling device includes a sampling probe 3, a connector 1, a sample lifting rod 4, and a handheld electric drill.

[0021] The sampling probe 3 is a hollow tubular structure, equipped with a connecting plate A3-3, a discharge pipe 3-2, and a cleaning pipe 3-1. The connecting plate A3-3 is an annular plate structure, concentric with the sampling probe 3 and located at the upper end of the sampling probe, for connection with the connector. The discharge pipe 3-2 and the cleaning pipe 3-1 are respectively connected to the inner cavity of the sampling probe 3. The discharge pipe 3-2 is located at the upper part of the sampling probe 3, and the discharge port is inclined downward; the cleaning pipe 3-1 is located between the discharge pipe 3-2 and the connecting plate A3-3, and is positioned higher than the discharge pipe 3-2.

[0022] The sampling probe 3 and the discharge pipe 3-2 are made of φ25 stainless steel pipe with a wall thickness of 2mm. The sampling probe 3 is 800mm long, and the connecting plate A3-3 is made of stainless steel with a thickness of 3mm. The cleaning pipe 3-1 is equipped with a φ10 quick connector and is connected to a compressed air pipe or a water pipe for passing water or compressed air through after sampling to clean and dry the sampling probe 3.

[0023] The sample lifting rod 4 is a straight rod structure with helical blades 4-1 on its outer circumference. The sample lifting rod 4 is inserted into the sampling probe 3, with its upper end protruding from the connector 1. The top of the sample lifting rod 4 is matched with a handheld electric drill, forming a drill connector 4-2, which is detachably connected to the drill. The rotation of the drill drives the sample lifting rod 4 to rotate clockwise or counterclockwise. The sample lifting rod 4 has dimensions of φ22×1200, a helical blade thickness of 0.3mm, and an effective lifting length of 800mm.

[0024] As a preferred option, the bottom end of the sampling rod 3 is beveled, which can reduce the resistance when inserting it into the ore pile during sampling; the lower end of the sample lifting rod 4 is conical, so that the lower end of the sample lifting rod 4 protrudes from the beveled bottom end of the sampling rod 3 during sampling.

[0025] Connector 1 includes a bottom connecting cylinder 1-2, a drill clasp 1-5, and a support rib 1-1. The support rib 1-1 connects the connecting cylinder 1-2 and the drill clasp 1-5. The drill clasp 1-5 consists of two semi-circular rings connected by a clamping bolt A1-3. The lower end of the drill (described in the orientation during use) is fixed by the drill clasp 1-5. The clamping bolt A1-3 enables the drill to be locked and then disassembled. By connecting the drill clasp 1-5 and the connecting cylinder 1-2 through the two support ribs 1-1, the dimensional adjustment range of the drill clasp 1-5 can be increased. During sampling, the sampling rod 3 is inserted into the interior of the ore pile from the surface of the ore pile. The overall structure of this utility model (with the orientation of the sampling rod 3) is vertical or nearly vertical. The electric drill is fixed on the electric drill retainer 1-5. The weight of the electric drill mainly acts on the sampling rod 3 and the sample lifting rod 4, which can effectively reduce the force required for the operator to hold the electric drill for sampling.

[0026] The bottom connecting cylinder 1-2 is provided with connecting discs B1-4 at its upper and lower ends respectively; the connecting disc A3-3 of the sampling probe 3 and the lower connecting disc B1-4 of the connecting cylinder 1-2 are connected by clamp 2. The clamp 2 is a ring with an opening, and the opening is connected by a clamping bolt B2-1. The clamp 2 is made of 0.5mm stainless steel.

[0027] A receiving bucket is provided below the discharge pipe 3-2.

[0028] Demonstration of the usage method of this utility model: (1) Connect the connecting plate A3-3 of the sampling rod 3 to the connecting plate B1-4 of the connector 1 with clamp 2, and tighten the clamp bolt B2-1.

[0029] (2) Connect the drill connector 4-2 of the sample lifting rod 4 to the hand-held drill; and insert the sample lifting rod 4 into the sampling probe 3 from above the connector 1, ensuring that the drill is fully inserted into the connector 1, and tighten the clamping bolt A1-3 to complete the assembly. The total weight of the weighing device is 2.8 kg.

[0030] (3) Place a sampling bucket below the discharge port of the discharge pipe 3-2, gently insert the bottom of the sampling rod 3 into the mineral powder pile, start the hand-held electric drill, and the mineral powder flows out from the direct discharge pipe 3-2. Repeat this step to complete the sampling of all sampling points. There are a total of 30 sampling points on site, which takes about 5 minutes.

[0031] (4) After sampling, connect the water pipe to the cleaning pipe 3-1, reverse the electric drill and connect the water pipe. After cleaning, close the water valve, then remove the water pipe, connect the compressed air to the cleaning pipe 3-1 and connect the compressed air to back-blown dry the sampling rod 3. The whole process takes about 1 minute. The cleaning and drying of the sampling rod 3 fully meets the requirements for continued sampling.

[0032] It is compatible with general handheld electric drills, requiring no dedicated power supply or fixed location, and is suitable for various scenarios such as bulk piles, bagged products, and truck beds. The length of the auger rod can be customized to cover shallow or deep sampling.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
