Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] The intelligent potato and offal sorting device comprises: a potato and offal conveying device, a potato and offal detecting device and a potato and offal sorting device. The potato and offal detecting device is installed on the upper front end of the potato and offal conveying device, and the potato and offal sorting device is installed on the side of the front end of the potato and offal conveying device.

[0022] The potato and offal conveying device 1 comprises a partition 101, a sensor 102, an angle steel 105, an inclined plate 106, a roller component 107, an electric roller 108, a support frame 109, a sprocket chain 110, a caster 111, and a flip drive block 112. The partition is installed on the upper part of the roller component and divides the roller component into six conveying channels. Two sensors are installed on one side of the support frame. The angle steel is installed on the upper end of the support frame to support the sprocket chain assembly. One end of the sprocket chain is driven by an electric roller. The electric roller is installed on the side end of the support frame. The sprocket chain assembly is provided with two groups. The roller components are evenly spaced between the two groups of sprocket chain components. The roller components are used to convey potato and offal. The flip drive block drives the roller component to rotate. The inclined plate is installed at the lower end of the roller component to receive the impurities that fall. Potatoes are conveyed to the roller conveying device through the feeding conveyor belt. The roller conveying device separates the potatoes under the action of speed increase, so that they fall into the potato holding position in the six channels divided by the partition and the roller component. The adjacent rollers and partitions form potato holding positions arranged vertically and horizontally due to the interval. The function of the partition is to separate the potatoes conveyed to the drum into six channels for conveying. The chain drive drives the drum and drives the potatoes to be conveyed forward in an orderly manner.

[0023] The potato and offal detection device 2 includes an industrial camera 201, a display screen 202, a strip light source 203, an industrial computer 204 and a control box 205; the camera is used to collect potato and offal images, the industrial computer is used to process the potato and offal images collected by the camera, the display screen is used to display the processing results, 6 strip light sources are arranged around the camera for fill light, and the control box is used to receive the result instructions of potato and offal image processing, and issue instructions to control the potato and offal sorting device to perform sorting. The roller conveying device has a total of 2 channel groups, and each 3 channels constitute a channel group. Each channel group is equipped with 2 industrial cameras in sequence in the direction of potato conveying. When the potato enters the image acquisition area, the photoelectric switch triggers all industrial cameras to collect images, and each industrial camera can collect potato images at 9 positions within the field of view. The trigger response beat of the photoelectric switch is triggered once per field of view. When two adjacent photoelectric switches are triggered, the flipping device drives the roller, and the potatoes flip under the drive of the roller, so that the front and back industrial cameras in the same channel group can respectively capture the front and back images of the potatoes, identify and process the front and back images of the potato offal in real time, and obtain the location information of the impurities and send it to the PLC.
