[0017] A use method of a sieving and mixing device for preparing hemp seed pulp powder as a raw material for bean curd, the use method comprising the following steps: Step one: pour the broken hemp seed slurry powder and soybeans from the feed inlet 3 into the cylinder 1, the slurry flows out from the screen hole 13, and the residue is retained in the cylinder 1; Step two: start the motor 2, the motor 2 drives the spiral plate 5 to rotate, and the spiral plate 5 pushes the residue to move to the hollow end of the cylinder 1 in the process of rotating, at the same time, the spiral plate 5 scrapes the inner wall of the cylinder 1, reducing the probability of the screen hole 13 being blocked; Step three: the residue is pushed by the spiral plate 5 to the lower end of the cylinder 73, and is blocked by the semicircular ring II 81, so that the residue is accumulated at the lower end of the cylinder 73 and is extruded, and the remaining slurry in the residue is discharged; Step four: when the residue accumulation continuously increases, the residue will push the semicircular ring II 81 to move, so that the insertion rod 82 is separated from the insertion hole 74, and the cylinder 73 is driven to rotate by the rotating shaft 4, and the residue is driven to the side surface of the push plate 62 by the partition plate 75; Step five: the push plate 62 pushes the residue out, so that it is discharged from the hollow end of the cylinder 1.
[0018] The working principle of the application is: pour the broken hemp seed slurry powder and soybeans from the feed inlet 3 into the cylinder 1, the slurry flows out from the screen hole 13, and the residue is retained in the cylinder 1; Start the motor 2, the motor 2 drives the rotating shaft 4 and the spiral plate 5 to rotate slowly (at this time, the sliding block I 43 is located in the annular groove II 44, the insertion block 82 is located in the corresponding insertion hole 74, the rotation of the cylinder 73 and the baffle 71 is limited, and the rotation of the sleeve 41 is limited), the spiral plate 5 pushes the residue in the cylinder 1 to move to the hollow end of the cylinder 1 in the process of rotating, at the same time, the spiral plate 5 scrapes the inner wall of the cylinder 1, reducing the probability of the screen hole 13 being blocked; The residue is pushed by the spiral plate 5 to the lower end of the cylinder 73 (i.e. the space surrounded by the lower outer wall of the cylinder 73, the partition plate 75, the bottom inner wall of the cylinder 1 and the semicircular ring II 81), and is blocked by the semicircular ring II 81, so that the residue is accumulated at the lower end of the cylinder 73 and is extruded, and the remaining slurry in the residue is squeezed out and discharged from the screen hole 13; When the residue accumulation continues to increase, the residue will push the semi-circular ring II 81 to move towards the hollow end of the cylinder 1. In the process of moving of the semi-circular ring II 81, the distance between the semi-circular ring II 81 and the semi-circular ring I 84 is reduced, so that the distance sensor 88 feeds back a signal to the processor, and then controls the electric telescopic rod 61 to retract. In the process of moving of the semi-circular ring II 81, the arc-shaped plate 83 is also moved, and then the connecting rod 86 is moved, so that the connecting rod 86 drives the sleeve 41 to move through the annular groove III 47. When the semi-circular ring II 81 continuously moves until the insertion rod 82 is separated from the insertion hole 74, the sliding block I 43 is separated from the annular groove II 44 and enters into the slide I 45. At this time, when the rotating shaft 4 rotates, the sliding block I 43, the sleeve 41 and the sleeve 41 are driven to rotate through the slide I 45. The sleeve 41 drives the baffle 71 to rotate through the slide II 42 and the sliding block II 72, and then drives the cylinder 73 to rotate, so that the cylinder 73 drives the separation plate 75 on the side thereof to drive the residue to rotate by 180°. Figure 1 As shown in the lower end of the cylinder 73, the residue is driven to the side of the push plate 62. After rotating by 180°, the semi-circular ring II 81 is no longer blocked by the residue under the elastic force of the spring II 85, so that the insertion block 82 is inserted into another insertion hole 74, and then the sleeve 41 is moved to the original position through the connecting rod 86, so that the sliding block I 43 is moved into the annular groove II 44 again. When the semi-circular ring II 81 moves to the original position (that is, the insertion block 82 is located in the insertion hole 74), the distance sensor 88 drives the electric telescopic rod 61 to stretch to the longest through the processor, so that the electric telescopic rod 61 is in contact with the end face of the spiral plate 5 close to the hollow end of the cylinder 1. With the rotation of the spiral plate 5, the electric telescopic rod 61 is pushed to move towards the hollow end of the cylinder 1, and then the push plate 62 is driven to move, so that the push plate 62 pushes the residue out, and the residue is discharged from the hollow end of the cylinder 1. In the process of moving of the push plate 62, the limiting block 63 drives the spring II 64 to compress. After the electric telescopic rod 61 is separated from the end of the spiral plate 5, the push plate 62 is driven to move to the original position under the elastic force of the spring II 64. When the electric telescopic rod 61 is retracted to the shortest under the signal, the push plate 62 is no longer in contact with the end face of the spiral plate 5, so that the push plate 62 remains in the original position and no longer moves.
