Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and in particular to a coal sampling device for automobiles entering the factory. Background Technology

[0002] The coal sampling device for trucks entering the factory is used to sample the coal carried by the trucks before they enter the factory, and then transport the coal to the next step for quality testing. This allows for quality analysis and control of the coal sample, and it is commonly used in the quality control and testing of bulk materials such as coal and ore.

[0003] In practical operation, sampling devices need to sample multiple batches and various types of coal. Existing sampling devices lack cleaning capabilities, and after prolonged use, residual coal slag (i.e., coal dust and fine coal particles) accumulates inside. This slag buildup affects the efficiency and accuracy of subsequent coal quality testing. Therefore, this application proposes a coal sampling device for trucks entering the factory with a cleaning function. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0025] See Figures 1-6 .

[0026] This utility model discloses a coal sampling device for vehicles entering the factory, comprising:

[0027] The sampling component 1 includes a vertically arranged first telescopic rod 11, with a spiral blade 12 on the telescopic end of the first telescopic rod 11. The first telescopic rod 11 is used to drive the spiral blade 12 to move up and down reciprocally. It also includes a sleeve 13 surrounding the first telescopic rod 11. The bottom of the sleeve 13 is a feed inlet 131. The sleeve 13 cooperates with the spiral blade 12 to transport coal. A first connecting rod 14 is also provided between the feed inlet 131 of the sleeve 13 and the bottom end of the telescopic end of the first telescopic rod 11. The first connecting rod 14 is rotatably connected to the first telescopic rod 11. The top of the first telescopic rod 11 is also provided with a power unit 15 for driving the first telescopic rod 11 to rotate.

[0028] Adjustment component 2 is disposed above sampling component 1. The sleeve 13 is vertically slidably disposed at one end of adjustment component 2, and the first telescopic rod 11 and the power unit 15 are both connected to adjustment component 2. Adjustment component 2 is used to drive sampling component 1 to move.

[0029] The cleaning component 3 includes a cleaning ring 31 slidably disposed within the sleeve 13. The cleaning ring 31 is used to clean coal slag adhering to the inner wall of the sleeve 13. The cleaning ring 31 is coaxially disposed with the first telescopic rod 11 and located in the gap between the sleeve 13 and the spiral blade 12. A brush 32 is also provided on the inner wall of the cleaning ring 31. The brush 32 is used to clean coal slag residue adhering to the spiral blade 12. A second connecting rod 33 for positioning the cleaning ring 31 is also provided between the cleaning ring 31 and the adjusting component 2.

[0030] In specific implementation, when the coal car moves to below the adjusting component 2, the adjusting component 2 drives the sampling component 1 to move to the predetermined sampling point above the coal pile, and drives the sampling component 1 to descend until the feed port 131 of the sleeve 13 and the bottom of the spiral blade 12 are inserted into the coal pile. At this time, the power unit 15 drives the spiral blade 12 to rotate through the first telescopic rod 11. The spiral blade 12 transports the coal block into the sleeve 13 to complete the sampling. When the work is completed, the first telescopic rod 11 retracts and drives the spiral blade 12 and the sleeve 13 to move upward together through the first connecting rod 14. At the same time, the power unit 15 still drives the spiral blade 12 to rotate through the first telescopic rod 11. At this time, the sleeve 13 moves upward relative to the cleaning ring 31. During the movement, the cleaning ring 31 scrapes off the coal slag attached to the inner wall of the sleeve 13 and discharges it through the feed port 131. The spiral blade 12 rotates while moving upward relative to the cleaning ring 31. At this time, the brush 32 is used to clean the coal slag attached to the spiral blade 12 and discharge it through the feed port 131.

[0031] In this invention, through the operation of the cleaning component 3, after the sampling component 1 completes the sampling work, the first telescopic rod 11 drives the sleeve 13 and the spiral blade 12 to move upward together. During the movement, the cleaning ring 31 scrapes off the coal slag attached to the inner wall of the sleeve 13. While the spiral blade 12 is moving, the power unit 15 drives the spiral blade 12 to rotate, so that the brush 32 can clean the coal slag attached to the spiral blade 12, avoid coal slag accumulation, and ensure the efficiency and accuracy of subsequent coal quality testing.

[0032] Preferably, the power unit 15 can be a motor from the prior art.

[0033] Preferably, the first telescopic rod 11 can be an electric push rod as in the prior art.

[0034] In one embodiment, the adjusting component 2 includes two opposing support frames 21, with a slide rail 22 between the two support frames 21. The two ends of the slide rail 22 are slidably mounted on the corresponding support frames 21. A moving platform 23 is also slidably mounted on the slide rail 22, and a lifting component 24 is also mounted on the moving platform 23. One end of the lifting component 24 is connected to the sampling component 1, and the sleeve 13 is vertically slidably connected to the lifting component 24. The slide rail 22 is used to drive the sampling component 1 to reciprocate along the length direction of the support frame 21, the moving platform 23 is used to drive the sampling component 1 to reciprocate along the length direction of the slide rail 22, and the lifting component 24 is used to drive the sampling component 1 to move vertically back and forth.

[0035] With this design, when the coal car moves between the two support frames 21, the sampling component 1 is moved to the predetermined collection point through the cooperation between the slide rail 22 and the moving platform 23. At this time, the lifting component 24 drives the sampling component 1 to move downward until the feed port of the sleeve 13 and the spiral blade 12 are inserted into the predetermined depth of the coal pile, thereby carrying out the sampling work. After the work is completed, the lifting component 24 drives the sleeve 13 and the spiral blade 12 to rise until they are removed from the coal pile.

[0036] In one embodiment, the lifting assembly 24 includes a second telescopic rod 241 vertically disposed at the bottom of the moving platform 23. The telescopic end of the second telescopic rod 241 has a chamber 2411, and the bottom of the chamber 2411 has an opening communicating with the outside. The power unit 15, the first telescopic rod 11 and the cleaning ring 31 are all disposed in the chamber 2411. The sleeve 13 is slidably inserted in the chamber 2411 and is coaxially disposed with the second telescopic rod 241. One end of the second connecting rod 33 is connected to the top of the chamber 2411 and the other end is connected to the cleaning ring 31.

[0037] With this design, when sampling is required, the telescopic end of the second telescopic rod 241 extends downward, allowing the inlet end of the sleeve 13 to be inserted into the coal pile. After the sampling is completed, the first telescopic rod 11 retracts and drives the spiral blade 12 and sleeve 13 to move upward and retract into the chamber 2411. At this time, the chamber 2411 provides sufficient space for the spiral blade 12 and sleeve 13 to move. After the cleaning ring 31 completes the cleaning of coal slag, the first telescopic rod 11 drives the spiral blade 12 and sleeve 13 to extend out of the chamber 2411 and move to the predetermined position.

[0038] In one embodiment, the sleeve 13 has a discharge port 132 on one side, and the cleaning ring 31 is disposed above the discharge port 132;

[0039] The telescopic end of the second telescopic rod 241 is provided with a first storage box 4 near the opening of its chamber 2411. The first storage box 4 is slidably connected to the outer wall of the sleeve 13. The first storage box 4 is also provided with a through hole corresponding to the discharge port 132. The first storage box 4 is used to store the coal collected by the spiral blade 12.

[0040] With this design, when the spiral blade 12 is conveying coal, the coal moves upward in the sleeve 13 as the spiral blade 12 rotates until it enters the first storage box 4 through the discharge port 132. Since the cleaning ring 31 is set above the discharge port 132, the coal will not come into contact with the cleaning ring 31 during the conveying process. When the first telescopic rod 11 drives the sleeve 13 to retract into the chamber 2411, the sleeve 13 moves upward relative to the first storage box 4. At this time, the discharge port 132 is misaligned with the opening of the first storage box 4, and the coal will not accidentally leak out of the first storage box 4 through the opening. When the first telescopic rod 11 drives the sleeve 13 to extend out of the chamber 2411, the sleeve 13 moves downward relative to the first storage box 4 until the discharge port 132 of the sleeve 13 corresponds to the opening of the first storage box 4. At this time, the sleeve 13 moves to the predetermined position and waits for the next operation.

[0041] In one embodiment, a second storage box 5 is provided on one side of the support frame 21. The top of the second storage box 5 is provided with a feed port. A storage cabinet 51 is also slidably provided in the second storage box 5. The storage cabinet 51 is used to store the coal slag cleaned out from the sleeve 13 and the spiral blade 12.

[0042] With this design, when cleaning the sleeve 13 and the spiral blade 12, the sampling component 1 is moved above the second storage box 5 through the cooperation between the slide rail 22 and the moving table 23. The sampling component 1 is then moved to a suitable height by the lifting component 24. At this time, the first telescopic rod 11 drives the sleeve 13 and the spiral blade 12 to rise and clean them through the cleaning component 3. The cleaning component 3 scrapes off the coal slag attached to the sleeve 13 and the spiral blade 12 and drops it into the storage cabinet 51 in the second storage box 5 through the feed port of the sleeve 13. When the storage cabinet 51 contains enough coal slag, the staff can pull the storage cabinet 51 out of the second storage box 5 and transfer it. It is convenient to use.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, "multiple," "multiple groups," and "several" refer to two or more.
