[0022] When it is necessary to sample powder raw materials of different depths, the staff first manually rotates the twist handle 507. After the twist handle 507 is rotated, it drives the screw rod 501 to rotate. When the screw rod 501 rotates, it cooperates with the slider 502 thread. Since the slider 502 is slidably sleeved on the guide rod 504, the guide rod 504 can limit the slider 502, and then when the screw rod 501 rotates, the slider 502 can slide on the screw rod 501. When the slider 502 moves, it drives the sleeve block 506 to move through the connecting rod 503. When the sleeve block 506 moves, it drives the sampling tube 1 to move through the sampling assembly 4, so that the vertical height of the sampling tube 1 can be adjusted. The staff can reasonably adjust the positions of multiple sampling tubes 1 according to the required insertion depth, so as to facilitate sampling of powder materials of different depths and improve applicability.

[0023] When the position adjustment of the sampling tube 1 is completed, the staff starts the motor 401. When the output end of the motor 401 rotates, it can drive the rotating shaft 402 to rotate. When the rotating shaft 402 rotates, it drives the spiral blade 403 to rotate. Then the staff drives the entire sampling assembly 4 and the adjustment mechanism 5 to move through the support plate 2, and inserts several sampling tubes 1 into the powder. When the spiral blade 403 rotates, the powder can be transported in the sampling tube 1 and stored in the collection device through the discharge port 103. Powders of different depths and layers can be taken at the same time, which is convenient for the staff to detect the powder in time. There is no need to repeatedly operate the sampling steps, which reduces the number of operations and effectively improves work efficiency.

[0024] In one embodiment, a plurality of notches 201 are formed on the top of the support plate 2 , and a plurality of handles 202 , switch buttons 203 and baffles 204 are fixedly mounted on the top of the support plate 2 .

[0025] When the position adjustment of the sampling tube 1 is completed, the staff holds the two handles 202 with both hands and presses the two switch buttons 203, so that the switch buttons 203 start the motor 401 to operate. Then the staff drives the entire sampling assembly 4 and the adjustment mechanism 5 to move through the handles 202 and the support plate 2, and inserts several sampling tubes 1 into the powder to realize the sampling work. Controlling the motor 401 through the switch button 203 can effectively reduce the difficulty of operation and improve applicability.

[0026] In one embodiment, a mounting seat 101 is fixedly mounted on the outer wall of the sampling tube 1 , a bolt 102 is fixedly mounted on the other end of the mounting seat 101 , and the outer wall of the bolt 102 is threadedly connected to the collecting tube 3 .

[0027] When the spiral blade 403 rotates, the powder can be transported in the sampling tube 1 and discharged into the collecting tube 3 through the discharge port 103. When a certain amount of powder is stored in the collecting tube 3, the collecting tube 3 is rotated so that the collecting tube 3 and the bolt 102 are threadedly matched, that is, the collecting tube 3 can be detached from the bolt 102, and the powder in the collecting tube 3 can be detected. The operation is simple, convenient for the staff to operate, and further improves the applicability.

[0028] The following is a detailed description of the working principle of the powder sampling mechanism used in concrete production:

[0029] When it is necessary to sample powder raw materials of different depths, the staff first manually rotates the twist handle 507. After the twist handle 507 is rotated, it drives the screw rod 501 to rotate. When the screw rod 501 rotates, it cooperates with the slider 502 thread. Since the slider 502 is slidably sleeved on the guide rod 504, the guide rod 504 can limit the slider 502, and then when the screw rod 501 rotates, the slider 502 can slide on the screw rod 501. When the slider 502 moves, it drives the sleeve block 506 to move through the connecting rod 503. When the sleeve block 506 moves, it drives the sampling tube 1 to move through the sampling assembly 4, so that the vertical height of the sampling tube 1 can be adjusted. The staff can reasonably adjust the positions of multiple sampling tubes 1 according to the required insertion depth, so as to facilitate sampling of powder materials of different depths and improve applicability.

[0030] When the position adjustment of the sampling tube 1 is completed, the staff member holds the two handles 202 with both hands and presses the two switch buttons 203, so that the switch buttons 203 start the motor 401 to operate. When the output end of the motor 401 rotates, it can drive the rotating shaft 402 to rotate, and when the rotating shaft 402 rotates, it drives the spiral blade 403 to rotate. Then the staff member drives the entire sampling assembly 4 and the adjustment mechanism 5 to move through the handles 202 and the support plate 2, and inserts a number of sampling tubes 1 into the powder. When the spiral blade 403 rotates, the powder can be transported in the sampling tube 1 and discharged into the collection tube 3 through the discharge port 103. Powders of different depths and layers can be taken at the same time, which is convenient for the staff to detect the powder in time, and there is no need to repeatedly operate the sampling steps, which reduces the number of operations and effectively improves work efficiency.

[0031] When a certain amount of powder is stored in the collecting tube 3, the collecting tube 3 is rotated so that the collecting tube 3 and the bolt 102 are threadedly matched, so that the collecting tube 3 can be separated from the bolt 102, and the powder in the collecting tube 3 can be detected. The operation is simple and does not require complicated operations, which is convenient for staff to operate and improves applicability.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
