[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The connecting pipe is connected to the pipe for conveying slurry through flanges at both ends. Move the intercepting pipe toward the connecting pipe to intercept the slurry in the connecting pipe.

A connecting plate 22 is fixedly connected to the end of the piston rod of the first driving cylinder 21. A limiting rod 23 is fixedly connected to the support frame 2 along the length direction of the piston rod of the first driving cylinder 21. The limiting rod 23 passes through the connecting plate 22, and the first driving cylinder 21 is started. During the movement of the connecting plate 22, the limiting rod 23 limits and guides the movement of the connecting plate 22 to improve the stability of the movement of the connecting plate 22.

[0032] Reference Figure 2The connecting plate 22 is fixedly connected to the side close to the connecting pipe 1 with an intercepting pipe 3. The connecting pipe 1 is provided with an opening corresponding to the intercepting pipe 3. The end of the intercepting pipe 3 away from the connecting plate 22 extends into the connecting pipe 1 through the opening. By starting the first driving cylinder 21, the intercepting pipe 3 moves in the connecting pipe 1 to intercept the slurry in the connecting pipe 1. The second driving cylinder 24 is installed on the side of the connecting plate 22 away from the intercepting pipe 3. The piston rod of the second driving cylinder 24 passes through the connecting plate 22 and penetrates into the intercepting pipe 3. The end of the piston rod of the second driving cylinder 24 is fixedly connected with a push rod 25 located in the intercepting pipe 3. The outer diameter of the push rod 25 is the same as the inner diameter of the intercepting pipe 3. The push rod 25 is driven by the second driving cylinder 24 to move in the intercepting pipe 3, and the push rod 25 pushes out the slurry intercepted in the intercepting pipe 3.

[0033] Reference Figure 1 A cleaning ring 12 is installed on the outer wall of the connecting pipe 1, and the intercepting pipe 3 passes through the cleaning ring 12. The inner wall of the cleaning ring 12 is in contact with the outer wall of the intercepting pipe 3. The ore slurry will adhere to the outer wall of the intercepting pipe 3. When the intercepting pipe 3 moves away from the feeding port 13, the cleaning ring 12 cleans the ore slurry adhered to the outer wall of the intercepting pipe 3.

During the process, a pressure is applied to the adjusting block 6 in the direction away from the feeding port 13, so that the adjusting block 6 moves in the direction away from the feeding port 13, and the feeding port 13, the feeding groove 51 and the feeding pipe 5 form a channel, and the slurry enters the receiving box 4 through the feeding groove 51 and the feeding pipe 5. A reset assembly 7 is provided on the inner wall of the feeding pipe 5, and the reset assembly 7 includes a connecting rod 71, a reset block 72 and a reset spring 73.

The reset spring 73 is connected to the adjusting block 6 and the feeding pipe 5. When the reset spring 73 is in a natural state, one end of the adjusting block 6 is located in the material taking port 13. When the adjusting block 6 moves away from the feeding port 13, the reset spring 73 is compressed. When the slurry sampling is completed, the pressure applied to the adjusting block 6 in the direction away from the feeding port 13 is stopped. The reset spring 73 applies a force to the adjusting block 6 in the direction close to the feeding port 13 through the reset block 72, so that the adjusting block 6 is reset to block the feeding port 13.
