A second feed hole 304 is opened on the lower side of the inner sleeve 206, and a sealing strip 305 is fixedly installed on the lower side of the inner sleeve 206.

[0028] According to the above solution, the inner sleeve can be rotated in the outer sleeve by turning the adjusting column in the adjusting groove, and the second feed hole can be kept sealed by the sealing strip.

[0029] In this embodiment, preferably, the sampling mechanism 103 includes a sampling piston 306 , a rotating column 401 is fixedly mounted on the bottom end of the sampling piston 306 , and a stirring blade 402 is fixedly mounted on the outer side of the rotating column 401 .

[0031] In this embodiment, preferably, a sealing groove 403 is opened at the top of the sampling piston 306 , a one-way valve plate 404 is fixedly installed around the sealing groove 403 , and a push-pull rod 405 is fixedly installed in the middle of the sealing groove 403 .

By rotating the sampling piston through the push-pull rod, the stirring blade can be rotated.

[0037] When using a sludge sampling device of this embodiment, the user moves the adjusting column 303 in the adjusting groove 106 to make the inner sleeve 206 rotate inside the outer sleeve 104, so that the first feed hole 201 and the second feed hole 304 are staggered, and at the same time, the adjusting knob 203 is turned to rotate the ball valve 204 to close the discharge pipe 202, and the adjusting screw 503 is turned to make the push-pull tube 406 drive the sealing card plate 501 to be pressed down into the sealing card groove 403 to press the one-way valve plate 404 to close, so that the sampling device is in a sealed state. State, at this time, the entire sampling device is inserted into the silt to be collected. It can be inserted into a certain depth inside the silt according to the collection depth requirement, and the adjustment column 303 is moved in the adjustment groove 106 so that the first feed hole 201 and the second feed hole 304 overlap. At this time, the silt outside the device will enter the device through the first feed hole 201 and the second feed hole 304, and then the sampling piston 306 is pushed and pulled by the push-pull plate 505 to form a negative pressure in the inner sleeve 206. At this time, a large amount of silt enters the collection device, and while pushing and pulling, the silt is pushed and pulled through the push-pull plate 505. 05 Turn the sampling piston 306 to make the stirring blade 402 rotate and stir to mix the sludge sample evenly. After collecting enough sludge samples, the first feeding hole 201 and the second feeding hole 304 are staggered by toggling the adjusting column 303 to prevent the sludge from flowing out. At this time, the collecting device is taken out upward and swung downward so that the solid matter accumulates toward the outlet under the action of gravity. At this time, the adjusting screw 503 is turned upward so that the push-pull tube 406 drives the sealing card plate 501 to rise and the one-way valve plate 404 can be opened. At the same time, the sampling piston 306 is pushed through the push-pull plate 505. The plug 306 squeezes the moisture in the collected sludge sample, and the water pressure pushes open the one-way valve plate 404 and flows out of the sampling device through the drainage groove. After the moisture is squeezed out, the adjusting screw 503 is turned to make the push-pull tube 406 drive the sealing card plate 501 to be pressed down into the sealing card groove 403 to press the one-way valve plate 404 tightly and close it. At this time, the adjusting knob 203 is turned to make the ball valve 204 rotate to open the discharge pipe 202, and the sampling piston 306 is pushed by the push-pull plate 505 to squeeze the sludge sample through the discharge pipe 202 into the sub-bottling bottle, completing the sludge collection work.
