For example, the angle between the first straight line 127 and the extending direction of the sliding chute 130 may be set to 85 °, 90 ° or 95 °, and the like, and similarly, the angle between the second straight line 128 and the extending direction of the sliding chute 130 may also be set to 85 °, 90 ° or 95 °, and the like, within which the transmission signal and the diffuse reflection signal of the rice can be detected normally. Therefore, when the use efficiency of the first image collector 123 and the second image collector 124 is considered, the increase of the flexibility of the position setting between the first background plate 125 and the first image collector 123 and the position setting between the second background plate 126 and the second image collector 124 are facilitated, the optimized layout of the positions of the components in the optical sorting module 120 according to actual needs is facilitated, and the connection stability and the detection accuracy are improved.
As shown in fig. 1, the feeding device 110 includes a feeding hopper 112, and a vibrating screen 114 connected to the feeding hopper 112, wherein the vibrating screen 114 is used for uniformly distributing the rice in the feeding hopper 112 and transferring the rice to the chute 130.

The unhulled rice conveyed to the sliding groove 130 is arranged in a single layer and slides down along the sliding groove 130, so that the detection effect is prevented from being influenced by the fact that the unhulled rice is stacked up due to too much sliding at one time. Therefore, the sliding rice can be fully detected, and the detection precision is favorably improved.
As shown in fig. 1, the first image collector 123 and the second image collector 124 correspond to an observation point 132 on the sliding chute 130, the observation point 132 is located within the range of the viewing angle of the first image collector 123 and the second image collector 124, and the rejecting device 140 is located below the observation point 132.
Specifically, when the transmission signal meets a set threshold, the diffuse reflection signal meets the set threshold, or the transmission signal and the diffuse reflection signal meet the set threshold at the same time, the controller controls the rejecting device 140 to be started, and because the rejecting device 140 is located below the observation point 132, the controller can delay the starting of the rejecting device 140 after acquiring the corresponding signal, so that rice to be rejected is purposefully rejected, the rejection error rate is reduced, and the purity of the sorted rice is improved.
As shown in fig. 4, the removing device 140 includes a gas source 142 and a plurality of spray valves 144 connected to the gas source 142, and the spray valves 144 can be respectively controlled to remove the rice at corresponding positions.
For example, when the transmission signal collected by the first image collector 123 or the diffuse reflection signal collected by the second image collector 124 satisfies a threshold, position information satisfying the threshold is recorded, respectively. The controller controls the spray valve 144 at the corresponding position of the removing device 140 to be started to remove the rice corresponding to the requirement. Therefore, the rice removing device 140 can remove good rice due to the fact that the removing range is too large, and the removing quality and stability can be improved.
