[0027] In order to achieve the purpose of fixing and limiting the telescopic mechanism 4, refer to Figure 2 The fixing mechanism 7 includes a fixing plate 71, and the lower part of the fixing plate 71 is fixedly connected with an oil-free bushing 72, which can guide the rotation of the piston rod of the rotary cylinder 61, and the upper left end of the outer surface of the fixing plate 71 is fixedly connected to the right part of the outer surface of the telescopic cylinder 42.

[0028] In order to achieve the purpose of connecting the output end of the telescopic cylinder 42 with the rotating mechanism 6, refer to Figure 3 The connecting mechanism 5 includes a connecting plate 51, and a floating joint 52 is fixedly connected to the upper left end of the outer surface of the connecting plate 51, which can connect the output end of the telescopic cylinder 42 with the connecting plate 51, and the left end of the outer surface of the floating joint 52 is fixedly connected to the output end of the right part of the telescopic cylinder 42.

[0033] The working principle of the present invention is as follows: when it is necessary to sample the powder transported in the inner cavity of the installation tube 1, the telescopic cylinder 42 is first driven to retract the output end of the piston rod while driving the connecting plate 51 and the rotary cylinder 61 to move back, so that the feeding tube 81 at the output end of the rotary cylinder 61 moves to the left so that the opening of the feeding port 82 extends into the inner cavity of the installation tube 1, so that the powder scattered in the inner cavity of the installation tube 1 will enter the inner cavity of the feeding tube 81 through the feeding port 82. Then, by manipulating the telescopic cylinder 42, its piston rod extends to the right, driving the connecting plate 51 to move to the right, and then the piston rod of the rotary cylinder 61 drives the feeding tube 81 to move to the right to the upper part of the fixed sleeve 31. At this time, by driving the rotary cylinder 61 to rotate 180 degrees, the powder collected in the inner cavity of the feeding tube 81 is rotated and poured into the inner cavity of the discharge chute 91 through the feed port 82, so that the powder falls along the inner wall of the discharge chute 91 into the inner cavity of the sample tank 92 for unified collection.
