In the first state, the separation valve 5 is used to allow the broken rice separated from the second separator 4 to flow into the second broken rice outlet pipe 25, and in the second state, the separation valve 5 is used to allow the whole rice separated from the second separator 4 to flow into the whole rice outlet pipe 26.

[0041] It can be understood that the mixed rice enters the first feeding chamber 11 through the mixed rice feed port, and during the rotation of the first feeding screw 14, the mixed rice in the first feeding chamber 11 is transported to the first separation chamber 12 through the first feeding port 13, and the mixed rice in the first separation chamber 12 is screened by the first separation element 3, so that a part of the broken rice in the mixed rice flows out through the first broken rice outlet pipe 15, thereby achieving the purpose of preliminary separation of the broken rice.

[0042] The remaining whole rice and part of broken rice in the first separation chamber 12 enter the second separation chamber 22 through the connecting pipe 27. During the rotation of the second feeding screw 24, the rice in the second feeding chamber 21 is transported to the second separation chamber 22 through the second feeding port 23. The separation valve 5 can be firstly placed in the first state. At this time, the broken rice in the second separation chamber 22 is separated by the second separation element 4, so that the part of broken rice flows out from the second broken rice outlet pipe 25.

[0043] It should be noted that the first feeding screw 14 and the second feeding screw 24 can be driven by driving motors respectively to ensure the rotation stability of the first feeding screw 14 and the second feeding screw 24 .

[0044] Embodiment 2:

[0045] The difference between this embodiment and the above embodiment is that;

[0046] like Figures 1 to 4 As shown, in some embodiments of the present invention, the first separating member 3 is a filter cartridge 31, the first feeding port 13 is located above the filter cartridge 31, the first feeding screw 14 is connected to the filter cartridge 31 to drive the filter cartridge 31 to rotate, and a plurality of first separating holes 311 are provided at intervals on the filter cartridge 31, the aperture of the first separating hole 311 is larger than the diameter of broken rice and smaller than the diameter of whole rice, so that the broken rice can enter the inner cavity of the filter cartridge 31, and the inner cavity of the filter cartridge 31 has a separation outlet, which is communicated with the first broken rice outlet pipe 15.

[0047] In some embodiments of the present invention, the inner surface of the inner cavity of the filter cartridge 31 is inclined toward the separation outlet to guide the broken rice into the first broken rice outlet pipe 15 .

Thus, the brushes 121 temporarily block the rice in the first separation chamber 12 from flowing downward, so that the filter cartridge 31 can allow as much broken rice as possible to enter the inner chamber during the rotation process, so as to better separate the broken rice.

[0049] It should be noted that when the amount of rice blocked by the brush 121 reaches a certain amount, under the action of gravity, the rice passes through the brush 121 and flows downward into the connecting pipe 27 to facilitate the next step of separation.

[0050] Embodiment three:

[0053] Thus, the size of the separation channel 43 is adjusted by moving the second sieve plate 42, so that when the diameter of the separation channel 43 is larger than the diameter of broken rice and smaller than the diameter of whole rice, the broken rice flows downward to the second broken rice outlet pipe 25 through the separation channel 43, and when the diameter of the separation channel 43 is larger than the diameter of whole rice, the whole rice enters the whole rice outlet pipe 26 through the diameter of the separation channel 43, thereby achieving the purpose of separating broken rice and whole rice.

[0054] In some embodiments of the present invention, a driving cylinder 6 is further included, the cylinder body of the driving cylinder 6 is connected to the outer side of the second barrel 2, the push rod of the driving cylinder 6 extends into the second separation chamber 22, and the push rod is connected to the second sieve plate 42 to drive the second sieve plate 42 to move. In this way, the movement of the second barrel 2 is facilitated.

[0055] In some embodiments of the present invention, a vibration motor 7 is provided on the second barrel 2, and the vibration motor 7 is arranged close to the second separator 4. Thus, the effect of the second separator 4 in separating broken rice and whole rice is improved through vibration.

[0056] In some embodiments of the present invention, the connecting pipe 27 is provided with a switch valve 271 for controlling the amount of rice entering the second feeding chamber 21 .

[0057] In some embodiments of the present invention, the separation valve 5 includes a valve plate 51 and a rotating shaft 52 disposed on the valve plate 51, the rotating shaft 52 is rotatably connected to the second barrel 2, in the first state, one end of the valve plate 51 abuts against the side wall of the second separation chamber 22 away from the second broken rice outlet pipe 25, the other end of the valve plate 51 abuts against the lower end of the second broken rice outlet pipe 25, and the valve plate 51 is inclined toward the second broken rice outlet pipe 25 to guide the broken rice into the second broken rice outlet pipe 25;

[0058] In the second state, one end of the valve plate 51 stops at the upper end of the second broken rice outlet pipe 25 to prevent whole rice from entering the second broken rice outlet pipe 25, and the other end of the valve plate 51 and the side wall of the second separation chamber 22 away from the second broken rice outlet pipe 25 define a rice outlet gap connected to the whole rice outlet pipe 26.

[0059] In some embodiments of the present invention, a rubber sealing strip 251 is provided at the lower end of the inlet of the second broken rice outlet pipe 25, and in the first state, the valve plate 51 abuts against the rubber sealing strip 251. Thus, when the broken rice is separated, the broken rice is prevented from entering the whole rice outlet pipe 26 below, thereby improving the separation effect.
