When a proper amount of coarse flour is in the net frame 13, the pushing plate 164 can be pushed to move downwards, the pushing plate 164 moves downwards to drive the second sliding rod 162 to move downwards, the fourth spring 163 is compressed, meanwhile, the pushing plate 164 moves downwards to drive the guide rod 166 to move downwards, the fifth spring 167 is compressed, the guide rod 166 moves downwards to drive the second sliding block 1611 to move downwards, the second sliding block 1611 moves downwards to drive the upper part of the movable plate 169 to swing downwards through the sliding groove 1610, the upper part of the movable plate 169 swings downwards to enable the lower part to swing upwards, the lower part of the movable plate 169 swings upwards to be in an inclined state, further, when the mesh-shaped block 155 moves downwards to be separated from the discharge port 154, the coarse flour falls onto the movable plate through the discharge port 154, the coarse flour falls into the container through the movable plate 169, when all coarse flour falls into the container, the pushing plate 164 can be loosened, and the guide rod 166 moves upwards to drive the second sliding block 1611 to move upwards due to the action of the fifth spring 167, and further drives the upper portion of the movable plate 169 to swing upward and return, and further the lower portion swings downward and returns, and due to the action of the fourth spring 163, the second sliding rod 162 moves upward and drives the pushing plate 164 to move upward and return. So, can need not to change the container and collect coarse flour, it is more convenient.

When the fine flour falls out through the discharging hopper 6, an operator can push the lower part of the connecting rod 18 to swing rightwards, the lower part of the connecting rod 18 swings rightwards to enable the upper part to swing leftwards, the sixth spring 20 is stretched, the upper part of the connecting rod 18 swings leftwards to drive the knocking ball 19 to swing leftwards, the knocking ball 19 swings leftwards without contacting with the discharging hopper 6, then the connecting rod 18 is loosened, and due to the action of the sixth spring 20, the upper part of the connecting rod 18 swings rightwards to drive the knocking ball 19 to swing rightwards to knock the discharging hopper 6, and the operation is repeated, so that the discharging hopper 6 can be knocked and vibrated continuously. Thus, the fine flour can fall out more quickly, and residues are avoided.

When a proper amount of coarse flour is in the net frame 13, the pull ring 25 can be pulled to move rightwards, the seventh spring 26 is stretched, the pull ring 25 moves rightwards to drive the clamping rod 23 to move rightwards, the clamping rod 23 moves rightwards to be separated from the clamping groove 24 below, the push plate 164 can be pushed to move downwards, the lower portion of the movable plate 169 swings upwards to be in an inclined state, further, when the clamping groove 24 above moves to the left side of the clamping rod 23, the pull ring 25 can be loosened, the pull ring 25 moves leftwards to drive the clamping rod 23 to move leftwards due to the effect of the seventh spring 26, and the clamping rod 23 moves leftwards to be clamped into the clamping groove 24 above to fix the guide rod 166. When the coarse flour completely falls into the container, the operation can be carried out according to the above, the pull ring 25 is pulled to move rightwards again, so that the clamping rod 23 is separated from the upper clamping groove 24, and then when the lower clamping groove 24 moves to the left side of the clamping rod 23, the pull ring 25 can be loosened, so that the clamping rod 23 is clamped into the lower clamping groove 24 again to fix the guide rod 166. Therefore, the operator is not required to push the push plate 164 all the time, and time and labor are saved.

It should be understood that this example is only for illustrating the present invention and is not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
