It should be noted that, first, the material tank 150 may be made of a transparent material, so that the light emitted from the first light source 121 and the second light source 122 can irradiate the rice. It is also advantageous for the first image collector 123 and the second image collector 124 to collect the transmission signal and the diffused reflection signal, respectively.

Second, the embodiments of the present invention do not specifically limit the form and number of the first light source 121 and the second light source 122. For example, the number of the first light sources 121 may be three, and in order to make the illumination more uniform, the first light sources 121 may be in the form of LED light bars. Similarly, the number of the second light sources 122 can be two, and in order to make the illumination more uniform, the second light sources 122 can also be in the form of LED light bars.

To improve the stability and accuracy of the first image collector 123 and the second image collector 124.

Alternatively, as shown in fig. 1 and 2, the first image collector 123 and the second image collector 124 are located on opposite sides of the chute 130.

Thus, the first image collector 123 and the second image collector 124 can respectively detect the front and the back of the rice, which is beneficial to detecting the transmission signal and the diffuse reflection signal of the rice in all directions, and further improving the accuracy of detection.

Alternatively, as shown in fig. 1 and 3, the first and second image collectors 123 and 124 are located on the same side of the chute 130.

Therefore, the first image collector 123 and the second image collector 124 can more fully utilize the first light source 121 and the second light source 122, so as to enhance the intensity of the rice transmission signal and the diffuse reflection signal, which is beneficial for the first image collector 123 and the second image collector 124 to respectively receive the transmission signal and the diffuse reflection signal, thereby improving the detection accuracy.

As shown in fig. 1, 2 and 3, an angle between the extending direction of the sliding groove 130 and a line (i.e., the first straight line 127) between the first background plate 125 and the first image collector 123 or an angle between the extending direction of the sliding groove 130 and a line (i.e., the second straight line 128) between the second background plate 126 and the second image collector 124 is 85 ° to 95 °.

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.

As shown in fig. 1, the material tank 150 includes a first chamber 152 and a second chamber 154, when the removing device 140 is activated, the removing device blows the removed rice away from the chute 130 and slides down the sliding plate 156 to the first chamber 152, and when the removing device 140 is stopped, the rice slides down the chute 130 to the second chamber 154.

Specifically, the chute 130 is provided with a notch, when the removing device 140 stops, the paddy directly slides to the second chamber 154 along the chute 130, and when the removing device 140 starts, the airflow blown out by the spray valve 144 blows the corresponding paddy out of the chute 130 from the notch on the chute 130 and slides into the first chamber 152 along the sliding plate 156, so as to realize the separation of the paddy, and separate the bad paddy from the good paddy, corresponding to the respective separation position.
