[0045] The bevel gear 30 has teeth only in some locations on its surface, and the number of teeth on the bevel gear 30 is equal to Thus, when the driving rod 24 rotates one circle, the rotating shaft 18 can be driven to rotate.

[0046] The top and bottom of the annular block 7 are respectively provided with a through groove 1 31 and a through groove 2 32 , and the through groove 1 31 , the through groove 2 32 and the filter tank 10 are all equal to the inner diameters of the pumping pipe 23 and the waste pipe 13 .

[0047] Among them, the pumping assembly also includes a discharge pipe 33 arranged concentrically with the pumping pipe 23 at the bottom of the annular bottom shell 4, and the waste discharge mechanism 12 also includes a waste discharge pipe 41 arranged concentrically with the waste discharge pipe 13 at the bottom of the annular bottom shell 4, and the pumping pipe 23, the discharge pipe 33, the waste discharge pipe 13, and the waste discharge pipe 41 are all connected to the interior of the annular bottom shell 4.

[0048] A limiting groove 39 is provided on the inner wall of the annular bottom shell 4 on the side away from the rotating shaft 18, and a connecting shaft 6 is provided on the side of the spherical block 9 away from the rotating rod 20. The other end of the connecting shaft 6 penetrates the annular block 7, and a strip-shaped limiting block 38 is provided at the end penetrating one end, and the strip-shaped limiting block 38 penetrates into the limiting groove 39;

[0049] The strip-shaped stopper 38 is disposed perpendicularly to the central axis of the filter tank 10 , so that when the strip-shaped stopper 38 is placed horizontally, the filter tank 10 can be kept in a vertical state.

[0050] The limiting groove 39 is composed of two narrow grooves 35 and two wide grooves 16, the two narrow grooves 35 and the two wide grooves 16 are connected end to end in sequence, and the connection between the wide groove 16 and the narrow groove 35 is transitioned by an inclined surface, the width of the narrow groove 35 is the same as the width of the strip limiting block 38, and the width of the wide groove 16 is equal to the length of the strip limiting groove 39;

[0051] The two wide grooves 16 correspond to the positions of the two groups of transmission teeth 22 respectively, that is, when the bevel gear 21 rotates on the transmission teeth 22 , the bar-shaped limit block 38 can rotate in the wide groove 16 .

[0052] Embodiment 1:

[0053] like Figure 6 As shown, in this embodiment, the number of the spherical block 9, the spherical groove 8 and the rotating rod 20 is preferably four.

[0054] like Figure 1-6 As shown in the figure, the curved rod 1 25 and the curved rod 29 are defined upward as 0 degrees of the driving rod 24, and the driving rod 24 rotates 360 degrees (i.e., one circle) as one cycle. During the process of the driving rod 24 rotating from 0 degrees to 180 degrees, the curved rod 1 25 drives the piston 1 40 to move downward through the connecting rod 1 36, and the slurry in the pumping pipe 23 passes through the filter tank 10 and the discharge pipe 33 in sequence, and is filtered by the filter plate 11 when passing through the filter tank 10, and the filtered matter is blocked by the filter plate 11;

[0055] When the slurry passes through the inner side of the filter tank 10 , the filter material contained therein will be intercepted by the filter plate 11 , and thus remain above the filter plate 11 ;

[0056] When the driving rod 24 rotates from 180 degrees to 360 degrees (i.e. 0 degrees), the crank rod 25 drives the piston 34 to rise through the connecting rod 36, thereby sucking the slurry from the feed pipe 2 into the pumping pipe 23;

[0057] It should be noted that a one-way valve 1 is provided on the inner side of the feed pipe 2, and a one-way valve 2 is provided in the discharge pipe 33. The one-way valve 1 allows the slurry to move only from the feed pipe 2 to the pumping pipe 23, and the one-way valve 2 allows the slurry to be discharged only from the pumping pipe 23 through the discharge pipe 33, so that sufficient pressure can be maintained in the pumping pipe 23 during the process of the piston 1 34 pumping the slurry.

[0058] like Figure 1-7 As shown, the curved rod 1 25 and the curved rod 29 are defined upward as 0 degrees of the driving rod 24, and the driving rod 24 rotates 360 degrees (i.e., one circle) as a cycle. In the process of the driving rod 24 rotating from 90 degrees to 270 degrees, the curved rod 29 drives the piston 27 to move downward in the filter tank 10 through the connecting rod 28, and then moves upward in the filter tank 10. In the process of the piston 27 moving downward in the filter tank 10, the slurry in the filter tank 10 is squeezed, and the filtered material at the bottom of the filter plate 11 is pushed into the waste pipe 41 for discharge through the slurry, thereby cleaning the filter plate 11. In the process of the driving rod 24 rotating from 270 degrees to 90 degrees, the curved rod 29 drives the piston 27 to move upward in the waste pipe 13 through the connecting rod 28, and then moves upward in the waste pipe 13;

[0059] It should be noted that a one-way valve three that can only be opened downward is provided at the center of the piston two 27, so that when the piston two 27 moves downward in the filter tank 10, it pushes the slurry in the filter tank 10. When the piston two 27 moves upward, the one-way valve three at the center of the piston two 27 opens downward to avoid sucking up the slurry again.

[0060] like Figure 1-6 As shown, the curved rod 1 25 and the curved rod 29 are defined upward as 0 degrees of the driving rod 24, and the driving rod 24 rotates 360 degrees (i.e. one circle) as a cycle. During the process of the driving rod 24 rotating from 270 degrees to 90 degrees, the teeth on the surface of the bevel gear 30 mesh with the bevel gear 2 37 and drive the bevel gear 2 37 to rotate 90 degrees, and the bevel gear 2 37 drives the rotating shaft 18 to rotate 90 degrees, so that the four spherical blocks 9 are all rotated 90 degrees in the same direction. During the process of the driving rod 24 rotating from 90 degrees to 270 degrees, the teeth on the bevel gear 30 do not mesh with the bevel gear 2 37. During this process, the rotating shaft 18 does not rotate. When the driving rod 24 continues to rotate, each spherical block 9 will cyclically pass under the pumping mechanism 1 and the waste discharge mechanism 12.

[0061] The purpose of such arrangement is that, when the piston 27 moves in the filter tank 10 , the spherical blocks 9 and the annular blocks 7 remain fixed and do not interfere with the piston 27 .

[0062] It should be noted that, in the process of the spherical block 9 rotating from the bottom of the piston 1 34 to the bottom of the piston 2 27, the bevel gear 1 21 on the surface of the rotating rod 20 connected to the spherical block 9 will mesh with a set of transmission teeth 22, and the bevel gear 1 21 will rotate 180 degrees through the transmission teeth 22, so that the spherical block 9 is flipped 180 degrees, so that the position of the filtered slurry is upward, and the filtered material retained by the filter plate 11 is downward, which is convenient for the waste discharge mechanism 12 to clean the filtered material. In the process of the spherical block 9 rotating from the bottom of the piston 27 to the bottom of the piston 1 34, the bevel gear 1 21 is meshed with another set of transmission teeth 22 again, and the spherical block 9 is flipped 180 degrees again to return to the initial state.

[0063] It should be noted that: during the flipping process of the spherical block 9, the strip limit block 38 is located in the wide groove 16 of the limit groove 39, and the width of the wide groove 16 is sufficient for the limit block 38 to rotate. When the spherical block 9 is located below the piston 1 34 and the piston 2 27, the strip limit block 38 is placed horizontally in the narrow groove 35 of the limit groove 39, so that the spherical block 9 cannot rotate.

[0064] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
