[0026] It can be seen from the above structure that; by setting the tank body 1, the feed port 2, the discharge port 2, the motor 4, the driving shaft 5, the extrusion block 6, the extrusion cylinder 7, the connecting block 11, the connecting rod 12, the rotating block 9, the cleaning brush 10 and the collecting device, when the tank body 1 is used for material crushing and mixing, the motor 4 will drive the driving shaft 5 and the extrusion block 6 to rotate, and the connecting block 11 fixedly connected to the bottom surface of the extrusion block 6 drives the rotating block 9 to rotate through the connecting rod 12, so that the cleaning brush 10 fixedly connected to the side wall of the rotating block 9 rotates along the upper surface of the filter screen 8, and then brushes away the blockage on the filter screen 8, and the collecting device can collect these blockages. The structure is simple, easy to use, and the filtering efficiency of the filter screen 8 is improved.

[0027] Furthermore, the collecting device includes a leakage hole 13 opened on the side wall of the rotating block 9, and the bottom surface of the filter screen 8 located below the leakage hole 13 is connected with a leakage pipe 14, the side wall of the leakage pipe 14 is connected with an inclined pipe 15, and the side wall of the tank body 1 located on one side of the inclined pipe 15 is fixedly connected with a collecting box 16, one end of the inclined pipe 15 penetrates the side wall of the tank body 1 and extends to the interior of the collecting box 16, and a sealing device is provided at the connection between the inclined pipe 15 and the collecting box 16, the side wall of the collecting box 16 is hinged with a box door 17, and one side of the box door 17 is provided with a box door bolt 18, one end of the box door bolt 18 penetrates the side wall of the box door 17 and is threadedly connected to the side wall of the collecting box 16; by setting the leakage hole 13, the leakage pipe 14, the inclined pipe 15, the collecting box 16, the box door 17, the box door bolt 18 and the sealing device, etc., the material put into the tank body 1 through the feed inlet 3 will fall from the bottom of the extrusion cylinder 7 to the top of the filter screen 8 after being crushed and mixed. The filter screen 8 is then filtered out through the outlet 3 and the filter 8 is then removed from the filter 8. The filter screen 8 is then filtered out through the outlet 3 and the filter 8 is then removed from the filter 8.

[0028] Furthermore, the blocking device includes a blocking groove 19 provided at the connection between the inclined tube 15 and the collecting box 16, and the side wall of the blocking groove 19 is slidably connected with a blocking plate 20, the side wall of the blocking plate 20 is rotatably connected with a fixing bolt 21, and the other end of the fixing bolt 21 passes through the side wall of the blocking groove 19 and is threadedly connected to the blocking groove 19; by setting the blocking groove 19, the blocking plate 20 and the fixing bolt 21 for use together, when the collecting box 16 needs to be cleaned, the fixing bolt 21 is rotated so that the fixing bolt 21 spirally moves forward to push the blocking plate 20 to slide along the blocking groove 19 to one side of the inclined tube 15, so that the inclined tube 15 can be closed, and then the collecting box 16 can be cleaned. After cleaning, the fixing bolt 21 is rotated in the opposite direction, and the retreating fixing bolt 21 will drive the blocking plate 20 to slide along the blocking groove 19, thereby clearing the inclined tube 15, so that the blockage in the inclined tube 15 can slide into the collecting box 16.
