Due to the limitation of the positioning block 12 and the existence of the inner tooth groove 11, when the movable rod 31 moves up and down, it will drive the rotating gear set 13 meshing with it to rotate, and then drive the rotating rod 14 to rotate, and finally make the crushing impeller 15 rotate;

[0047] By providing a crushing structure, the incoming impurities are crushed, thereby preventing garbage from being blocked in the transition box 3, resulting in the inability to perform normal sludge extraction work.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the utility model, the hydraulic structure includes a hydraulic valve 2 and a hydraulic telescopic piston 5. The hydraulic valve 2 is fixedly mounted on the top of the right side of the mounting seat 1, and the hydraulic telescopic piston 5 is movably arranged on the sleeve 4 to control the changes in the internal pressure of the sleeve 4 and the transition box 3.

[0049] In the embodiment of the utility model, when in use, the hydraulic valve 2 is activated, so that the hydraulic telescopic piston 5 is raised and lowered, thereby changing the change of the internal pressure of the sleeve 4 and the transition box 3;

[0050] By setting up a hydraulic structure, it is convenient to control the changes in the internal pressure of the sleeve 4 and the transition box 3.

[0051] like Figure 6As shown, as a preferred embodiment of the utility model, the ejection groove 28 is arranged in an isosceles triangle shape, and the inner end of the ejection rod 22 is arranged in a right triangle shape, which corresponds to the position of the inner end after the ejection groove 28 extends out.

[0052] In the embodiment of the utility model, when in use, the ejection groove 28 is set to an isosceles triangle shape, and the inner end of the ejection rod 22 is set to a right triangle shape, and corresponds to the position of the inner end after the ejection groove 28 is extended. When the ejection rod 22 is extended, the inner side of the ejection groove 28 is squeezed to move inward, thereby causing it to contract.

[0053] like Figure 6 As shown, as a preferred embodiment of the present utility model, a limiting groove 29 is provided in the middle of the second limiting block 27 , and a limiting plate 30 is arranged inside the limiting groove 29 and is fixedly connected to the first limiting block 20 .

[0054] In the embodiment of the utility model, when in use, a limiting groove 29 is opened in the middle of the second limiting block 27, and a limiting plate 30 is arranged inside the limiting groove 29 and fixedly connected to the first limiting block 20, so that when the second limiting block 27 is extended, the position of the limiting plate 30 in the limiting groove 29 will be changed, thereby constraining it.

[0055] like Figure 1 As shown, as a preferred embodiment of the utility model, the surfaces of the inlet and outlet 6 on the front and rear sides are both provided with one-way valves 7, and the blocking directions of the one-way valves 7 on the front and rear sides are opposite.

[0056] In the embodiment of the utility model, when in use, one-way valves 7 are provided on the surfaces of the inlet and outlet 6 on both the front and rear sides, and the blocking directions of the one-way valves 7 on the front and rear sides are opposite, thereby facilitating the entry and exit of sludge.

[0057] The above embodiment of the utility model provides a hydraulic high-pressure mud pump. When in use, the mounting seat 1 is installed at a designated place, and then the hydraulic valve 2 is started to control the hydraulic telescopic piston 5 on the top of the sleeve 4 to be telescopic, so that negative pressure is generated in the transition box 3, and the front one-way valve 7 is opened, and then the sludge is pumped into the transition box 3 through the front inlet and outlet 6, and then crushed. Then, with the movement of the hydraulic telescopic piston 5 again, the pressure is completed. Due to the restriction of the front one-way valve 7, the sludge can only open the rear one-way valve 7 under the action of pressure, and then be discharged through the rear inlet and outlet 6, thereby completing one extraction and discharge work;

[0058] When the hydraulic telescopic piston 5 moves, it will drive the lifting rod 10 to move up and down, and then drive the movable rod 31 to move up and down through the positioning rod 16. Due to the limitation of the positioning block 12 and the existence of the inner tooth groove 11, when the movable rod 31 moves up and down, it will drive the rotating gear set 13 meshing with it to rotate, and then drive the rotating rod 14 to rotate, and finally make the crushing impeller 15 rotate to crush the impurities entering, so as to avoid the garbage being blocked in the transition box 3, resulting in the inability to carry out normal sludge extraction work;

[0059] When it is necessary to clean and maintain the interior of the transition box 3, a finger is inserted into the pull ring 24 to squeeze the outer side of the ejector rod 22, thereby overcoming the elasticity of the first spring 23, and then moving along the second movable groove 21, and then abutting against the inner side of the ejector groove 28 on the surface of the second limit block 27, so that it overcomes the elasticity of the second spring 26, and then separates from the card groove 18, so that it can be pulled to the first limit block 20, so that the inner end of the first movable groove 19 is in the first movable groove 19, thereby releasing the connection with the sealing top cover 17, so that the sealing top cover 17 can be removed, thereby facilitating cleaning and maintenance.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
