[0025] Please see the attached Figure 1 -Attached Figure 9In a preferred embodiment, the sampling mechanism includes: a partition plate 18, which is fixedly installed at the center of the sampling rod 4, and a sampling barrel 17 is rotatably installed on the bottom of the sampling rod 4 and the top surface of the partition plate 18. The partition plate 18 is used to divide the interior of the sampling rod 4 into two spaces, so as to realize sampling of powders of different depths. A rectangular opening 20 is provided on the surface of each sampling barrel 17, and a feeding port 8 symmetrically arranged with the two rectangular openings 20 is provided on the surface of the sampling rod 4, and the two feeding ports 8 are centrally symmetrically arranged, which are used to sample and temporarily store the powder inside the powder tank truck. The rectangular opening 20 facilitates the powder to enter the sampling barrel 17 after passing through the feeding port 8.

[0026] Please see the attached Figure 1 -Attached Figure 9 In a preferred embodiment, the top surfaces of the two sampling barrels 17 are embedded with one-way bearings 19, and the two one-way bearings 19 are in opposite directions. A telescopic rod 12 is vertically arranged inside the sampling rod 4. The fixed end and the telescopic end of the telescopic rod 12 are connected by a spline sliding connection, indicating that the length of the telescopic rod 12 is adjustable, and the end of the telescopic rod 12 passes through the sampling barrel 17 and the dividing plate 18 located above. The inner rings of the two one-way bearings 19 are fixedly sleeved on the surface of the telescopic rod 12, so that when the telescopic rod 12 rotates in different directions, the two sampling barrels 17 can be driven to rotate respectively, so that the two sampling barrels 17 can sample powders of different depths.

[0027] Please see the attached Figure 1 -Attached Figure 9 In a preferred embodiment, two insertion rods 22 are horizontally arranged in a centrally symmetrical manner inside the sampling rod 4. The surface of the insertion rod 22 slides through the surface of the sampling rod 4 through a spline. A sleeve 23 is fixedly sleeved on the surface of the insertion rod 22, and an L-shaped plate 25 is also adapted to limit the movement of the sleeve 23 inside the sampling rod 4. Two conical blocks 21 are fixed on the surface of the telescopic rod 12, and a spring 24 is sleeved on the surface of the insertion rod 22. The two ends of the spring 24 are respectively installed on the inner wall of the sampling rod 4 and the side of the corresponding sleeve 23. The insertion rod 22 is used to be inserted into the interior of the tank truck, so that the powder at the sampling point breaks the arch, and the powder at the feeding port 8 has good fluidity and can be smoothly taken.

[0028] Please see the attached Figure 1 -Attached Figure 7 In a preferred embodiment, the top end of the telescopic rod 12 passes through the first screw 9 and the second screw 11, the telescopic rod 12 and the second screw 11 do not contact each other, the surface of the telescopic rod 12 and the inner wall of the first screw 9 are rotatably arranged, the top surface of the first screw 9 is fixedly sleeved with a first knob 6, and the top surface of the telescopic rod 12 is fixedly sleeved with a second knob 7. The first screw 9 and the telescopic rod 12 can be controlled respectively by the first knob 6 and the second knob 7.

[0029] Please see the attached Figure 1In a preferred embodiment, two symmetrically arranged handles 5 are fixed on the surface of the first extension rod 1, and the handles 5 are convenient for workers to hold while working.

[0030] When it is necessary to sample and test the powder in the powder tank truck, the first extension rod 1 is lifted by the handle 5, and then the first knob 6 is turned to drive the first screw 9 to rotate. The rotation of the first screw 9 drives the second extension rod 2 to move and extend the first extension rod 1. At the same time, the rotation of the first screw 9 also drives the second screw 11 to rotate; The second extension rod 2 moves through the fixed plate 13 to drive the U-shaped rod 15 to move, and the movement of the U-shaped rod 15 drives the second screw rod 11 to move. The movement of the second screw rod 11 at this time will drive the third extension rod 3 to move. This is one-stage movement of the third extension rod 3. In addition, the rotation of the second screw rod 11 will also drive the third extension rod 3 to move. This is a two-stage movement of the third extension rod 3. Therefore, the second extension rod 2 and the third extension rod 3 can be synchronously extended from the inside of the first extension rod 1, and the second extension rod 2 and the third extension rod 3 are divided into multiple stages of movement, so that the length of the sampling device is extended longer for convenient sampling. Similarly, when not in use, the length of the device can be reduced to a short enough length for easy carrying; When the third extension rod 3 drives the sampling rod 4 to the position where sampling is required, the telescopic rod 12 is rotated by twisting the second knob 7 180 degrees in the forward direction. The rotation of the telescopic rod 12 drives the sampling barrel 17 connected thereto to rotate through the one-way bearing 19 located below. Since the two one-way bearings 19 are arranged in opposite directions, the telescopic rod 12 will not drive the sampling barrel 17 above to rotate. When the sampling barrel rotates until the rectangular opening 20 coincides with the material removal port 8, the powder inside the tanker will enter the sampling barrel 17 through the rectangular opening 20; In addition, the rotation of the telescopic rod 12 will also drive the rotation of the conical block 21, and the rotation of the conical block 21 will drive the insertion rod 22 to move and make the spring 24 generate elastic force. The movement of the insertion rod 22 will extend the sampling rod 4, and further squeeze the powder near the sampling inside the tank truck, thereby breaking the arch of the powder inside the tank truck, ensuring the smoothness of the powder sampling of the feeding port 8 and the rectangular opening 20. Finally, the second knob 7 is rotated forward 180 degrees again to block the rectangular opening 20, and the conical block 21 and the insertion rod 22 will also separate, and the tip of the insertion rod 22 will be reset to the inner wall of the sampling rod 4, and will not bring resistance when the equipment is lifted; By the same token, when the second knob 7 is twisted 180 degrees in the opposite direction to rotate the telescopic rod 12, the sampling cylinder 17 at the top will rotate to sample the powder, while the sampling cylinder 17 at the bottom will not rotate; In summary, the powder inside the powder tank truck can be sampled quickly, stably and efficiently, and the volume of the sampling object can be reduced after sampling, ensuring the portability of the sampling object, thereby improving the use effect of the equipment.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
