[0032] In this embodiment, by providing the connecting plate 16 , the support tube 2 and the sampling tube 1 can be conveniently connected and installed, and at the same time, the raw material can be conveniently introduced into the sampling tube 1 .

[0033] As a technical optimization solution of the utility model, a moving groove 17 for use with the stud 5 is opened on the left side of the support tube 2 , and the stud 5 is located in the inner cavity of the moving groove 17 .

[0034] In this embodiment, the movable groove 17 is provided to guide and limit the stud 5 .

[0035] Working principle: when it is necessary to sample the concrete raw material, the staff moves the handle 9 so that the handle 9 drives the device to move and insert into the inner cavity of the concrete raw material. When the sampling tube 1 is inserted to a suitable sampling depth, the staff rotates the limit nut 6 so that the limit nut 6 drives the rubber pad 7 to rotate and move on the outer surface of the stud 5 away from the support tube 2, thereby releasing the limit on the driving rod 4. Then, the staff pulls the limit nut 6 upward so that the limit nut 6 drives the stud 5 to slide upward on the inner surface of the moving groove 17. At the same time, the stud 5 drives the driving rod 4 to move upward, and the driving rod 4 drives the limit plate 13 to slide on the inner surface of the limit groove 14. In addition, the driving rod 4 drives the push plate 3 to move upward and out of the inner cavity of the sampling tube 1. At the same time, the concrete raw materials enter the inner cavity of the sampling tube 1 through the gaps between the connecting plates 16 on both sides.

[0036] When sampling is completed, the staff moves the limiting nut 6 again, so that the limiting nut 6 drives the stud 5 to slide downward on the inner surface of the moving groove 17. At the same time, the stud 5 drives the driving rod 4 to move downward, so that the driving rod 4 drives the push plate 3 to move downward into the inner cavity of the sampling tube 1 to achieve sealing of the sampling tube 1. Then, the staff moves the handle 9 upward, so that the handle 9 drives the device to move out the concrete raw material. Then, the staff rotates the limiting nut 6 in the opposite direction, so that the limiting nut 6 drives the rubber pad 7 to rotate in the opposite direction on the outer surface of the stud 5 and fits tightly with the connection between the support tube 2, thereby limiting the driving rod 4 to prevent the push plate 3 from moving and causing the concrete raw material sample to spill.

[0037] Then, the staff moves the handle 9 so that the handle 9 drives the device to move above the sample storage box. Then, the staff rotates the movable tube cover 8 so that the tube cover 8 drives the cone head 12 away from the sampling tube 1, so that the concrete sample slides into the inner cavity of the sample storage box. At the same time, the staff rotates the limit nut 6 again so that the limit nut 6 drives the rubber pad 7 to rotate and move on the outer surface thread of the stud 5 away from the support tube 2, thereby releasing the limit on the driving rod 4. Then, the staff pushes the limit nut 6 downward so that the limit nut 6 drives the stud 5 to slide downward on the inner surface of the moving groove 17. At the same time, the stud 5 drives the driving rod 4 to move downward, so that the driving rod 4 drives the push plate 3 to slide downward in the inner cavity of the sampling tube 1, thereby completely pushing out the concrete sample for discharging, and preventing the concrete sample from adhering to the inner cavity of the sampling tube 1. The device is simple to operate and convenient for sampling and discharging, thereby avoiding incomplete discharging of raw materials, resulting in mixing when sampling next time, resulting in errors in detection, and at the same time, it can meet the customer's usage needs.
