[0029] The extraction mechanism 4 includes a primary extraction tube 401, a middle extraction tube 402 and a bottom extraction tube 403 bolted to the bottom of the solid plate 3, and electric push rods 404 are arranged on the front side and both sides of the top of the solid plate 3. The telescopic end of the left electric push rod 404 penetrates the solid plate 3 and the top of the primary extraction tube 401 in sequence, the telescopic end of the right electric push rod 404 penetrates the solid plate 3 and the top of the middle extraction tube 402 in sequence, the telescopic end of the front electric push rod 404 penetrates the solid plate 3 and the top of the bottom extraction tube 403 in sequence, the telescopic end of the electric push rod 404 is bolted with a piston 405, the bottom sides of the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube 403 are rotatably connected with a pad 406, and the bottoms of the outer sides of the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube 403 are connected with a drain valve 407.

[0030] In this embodiment: by setting the lifting mechanism 2 and the extraction mechanism 4, the operator holds the handle 1 and adjusts the height of the solid plate 3 and the extraction mechanism 4 through the lifting mechanism 2, so as to accurately place the extraction mechanism 4 in the sludge environment of different depths. When different layers of sludge need to be extracted, the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube 403 at the bottom of the solid plate 3 correspond to different sludge layers respectively, and the electric push rod 404 is started. The left electric push rod 404 pushes the piston 405 connected to the telescopic end to move in the primary extraction tube 401, the right electric push rod 404 pushes the piston 405 to move in the middle extraction tube 402, and the front electric push rod 404 pushes the piston 405 to move in the bottom extraction tube 403.

[0034] In this embodiment: by setting up a lifting mechanism 2, the electric telescopic rod 203 can be extended and retracted to drive the connecting plate 204 to move up and down, thereby adjusting the height of the fixed plate 3 and the extraction mechanism 4, so that the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube 403 can adapt to the sludge environment of different depths for precise extraction operations.

[0037] In this embodiment: the battery 5 provides power support for the electric push rod 404 and the electric telescopic rod 203 to ensure the normal operation of the device. The setting of the controller 6 allows the operator to easily control the electric push rod 404 and the electric telescopic rod 203 to achieve precise operation, thereby improving the degree of automation and operational convenience of the device.

[0038] Specifically, Figure 4 As shown, a reinforcing rod 7 is bolted in the middle of the bottom of the hanging plate 202 , and the bottom of the reinforcing rod 7 is located on the inner side of the primary extraction pipe 401 , the middle extraction pipe 402 and the bottom extraction pipe 403 .

[0039] Specifically, Figure 5 As shown, a rubber sleeve 8 is sleeved on the front side of the outer side of the handle 1, and an anti-skid pattern is provided on the outer side of the rubber sleeve 8.

[0040] In this embodiment: by arranging a reinforcement rod 7, the reinforcement rod 7 is located on the inner side of the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube 403, the overall structural stability of the device is further enhanced, and by arranging a rubber sleeve 8, the rubber sleeve 8 increases the comfort of holding the handle 1, and the anti-slip texture on the outer side increases the friction of the handle 1, which is convenient for the operator to hold, thereby improving the safety and comfort of the operation.

[0041] Working principle: When using the stratified extraction environmental sludge pushing device, the operator first holds the handle 1, starts the battery 5 through the controller 6 to power the electric telescopic rod 203, and the electric telescopic rod 203 is extended and retracted to drive the connecting plate 204 to move up and down, thereby adjusting the height of the fixed plate 3 and the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube, and accurately placing the primary extraction tube 401, the middle extraction tube 402 and the bottom extraction tube 403 in the sludge environment at different depths. When different layers need to be extracted, When the sludge is extracted for the first time, the primary extraction pipe 401, the middle extraction pipe 402 and the bottom extraction pipe 403 at the bottom of the solid plate 3 correspond to different sludge layers respectively, and then the electric push rod 404 is started through the controller 6, the left electric push rod 404 pushes the piston 405 connected to the telescopic end to move in the primary extraction pipe 401, the right electric push rod 404 pushes the piston 405 to move in the middle extraction pipe 402, and the front electric push rod 404 pushes the piston 405 to move in the bottom extraction pipe 403, and the movement of the piston 405 generates a negative The sludge is sucked into the corresponding primary extraction pipe 401, the middle extraction pipe 402 and the bottom extraction pipe 403 by pressure. In this process, the pad 406 that is rotatably connected to the bottom side of the primary extraction pipe 401, the middle extraction pipe 402 and the bottom extraction pipe 403 is in an open state, which facilitates the sludge to enter the primary extraction pipe 401, the middle extraction pipe 402 and the bottom extraction pipe 403 smoothly. When the extraction is completed, the pad 406 is rotated to a closed state to prevent the sludge from leaking. If the sludge is to be discharged for subsequent operations such as testing, To operate, one only needs to open the discharge valve 407 at the bottom outside of the primary extraction pipe 401, the middle extraction pipe 402 and the bottom extraction pipe 403 to achieve fast and smooth discharge. The reinforcement rod 7 in the middle of the bottom of the hanging plate 202 further enhances the overall structural stability of the device. The rubber sleeve 8 on the outside of the handle 1 and its anti-slip texture improve the safety and comfort of operation. The clear division of labor and synergistic effect of each component greatly improves the accuracy, stability and reliability of sludge extraction, while reducing the difficulty of operation and the complexity of troubleshooting.
