[0033] As Figures 1 - 4 shown, the dredging component 4 includes a first connecting pipe 401, a second connecting pipe 402, a third connecting rod 403 and a nozzle 404. The top and bottom of the second connecting pipe 402 are respectively fixedly connected to the first connecting pipe 401 and the second connecting pipe 402. Connect the water outlet pipe to the left or right side of the first connecting pipe 401 on the front and back sides, and open the valve on its side. Water enters the first connecting pipe 401, enters the third connecting rod 403 through the second connecting pipe 402. The bottom of the third connecting rod 403 is fixedly installed with nozzles 404 at equal intervals, so that water enters the nozzles 404 from the third connecting rod 403 and sprays out from the nozzles 404. The nozzles 404 are aligned with the inner front and rear walls of the housing 1, and the impact force of the nozzles 404 is relatively large. A plurality of drain holes 6 are opened at the bottom of the housing 1, so that the nozzles 404 wash away the blocked impurities inside, thereby automatically dredging the drain holes 6;

[0034] The first connecting component 3 includes a clamping plate 301 and a clamping groove 302. The clamping plate 301 is fixedly connected to the outer bottom of the cover plate 12, and the clamping groove 302 is opened at the top of the housing 1. When disassembling the dredging component 4, hold the handles on both sides of the top of the cover plate 12 and lift it upward to disassemble the cover plate 12. The first connecting pipe 401 and the third connecting rod 403 are respectively arranged at the top and bottom of the cover plate 12, and the second connecting pipe 402 is arranged inside the cover plate 12, so as to disassemble the dredging component 4.

The first threaded hole 903 at the top end of the outer rod 901 and the first threaded hole 903 in the inner rod 902 aligned with it are internally threaded with the first threaded rod 904. When both the first threaded rods 904 on the left and right sides are screwed out of the first threaded hole 903 in the inner rod 902, the inner rod 902 moves downward. The top end of the inner rod 902 is fixedly connected to the waste water hopper 7 through a plate member, so that the inner rod 902 drives the waste water hopper 7 to move downward, so that the inside of the waste water hopper 7 leaves the bottom of the outer shell 1, so that the distance between the top end of the waste water hopper 7 and the bottom of the outside of the outer shell 1 can place cleaning tools. Align the first threaded hole 903 at the top end of the outer rod 901 with one of the first threaded holes 903 in the inner rod 902, and screw in the first threaded rod 904 for fixation to fix the inner rod 902, thereby fixing the waste water hopper 7. Then the staff uses cleaning tools to repeatedly brush inside the waste water hopper 7, so as to comprehensively clean the inside of the waste water hopper 7. When the waste water hopper 7 fits with the bottom of the outer shell 1, screw out the first threaded rod 904 again, pull the inner rod 902 upward, and make the left side of the waste water hopper 7 fit with the bottom of the outer shell 1;

[0038] Embodiment 3: The existing screw press conveyor is not convenient for cleaning the inside of the outer shell 1. To solve this technical problem, the following technical content is disclosed in this embodiment:

[0039] As shown in Figure 6 and Figure 7 the figure, the cleaning mechanism 15 includes a motor 1501, a lead screw 1502, a cleaning brush 1503 and a fixed shell 1504. When cleaning the inside of the outer shell 1, remove the cover plate 12, hold the handle at the top end of the outer side of the fixed shell 1504. On both the left and right sides at the bottom of the outer side of the fixed shell 1504, clamping plates 301 are fixedly installed. Clamp the clamping plates 301 into the clamping grooves 302 at the top end of the outer shell 1. Start the motor 1501. The output end of the motor 1501 is fixedly connected to the lead screw 1502. The motor 1501 drives the lead screw 1502 to rotate. The cleaning brush 1503 is threadedly connected to the outside of the lead screw 1502. The rotating lead screw 1502 drives the cleaning brush 1503 to move left and right. The cleaning brush 1503 is attached to the inner wall of the outer shell 1, and the inner circle of the cleaning brush 1503 is attached to the propeller of the spiral component 2, so as to facilitate cleaning the inner wall of the outer shell 1 and the propeller of the spiral component 2. When disassembling the cleaning mechanism 15, hold the handle at the top end of the outer side of the fixed shell 1504 and lift it up;

[0040] Working principle: Pour the sewage into the housing 1 through the feed pipe orifice 5 fixedly connected to the right side of the top of the cover plate 12. Start the power equipment of the screw assembly 2, which drives the propeller of the screw assembly 2 to rotate. The propeller transports the grid residues in the sewage to the left, so that the grid residues go out from the discharge pipe orifice 13 fixedly connected to the left side of the bottom of the housing 1. A waste water hopper 7 is arranged below the drain hole 6 at the bottom of the housing 1. The sewage carried by the grid residues flows into the waste water hopper 7 through the drain hole 6.
