When the separating mechanism 2 separates the areca nuts one by one, the blanking mechanism 3 starts to function. Firstly, the rotation of the blanking chain 37 drives the blanking supporting plate 31 mounted on the blanking chain 37 to move to the feeding tool 32. At the feeding station 32, the feeding supporting plate 31 can receive the areca nuts separated from the material separating mechanism 2, then continue to move along with the feeding chain 37, convey the areca nuts to the visual detection module 4, take a picture through a visual camera at the visual detection module 4, analyze the length, the size and the surface lines of the areca nuts on each flow channel, obtain different data results, and divide the areca nuts into different grades according to the data results. After the detection is finished, the betel nuts are conveyed to the blanking station 34 through the transmission of the blanking chain 37, and the fourteen row material outlets 33 are arranged on the blanking station 34, so that the betel nuts can be classified into fourteen grades. The blanking station 34 pushes down the betel nuts from the discharge port 33 by the action of the pushing assembly 35, and then collects the betel nuts of different grades through the collecting hopper 36. Finally, the bottoms of the collecting hoppers 36 are connected with corresponding conveying channels, so that classified betel nuts are conveyed to the next processing procedure.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. Those skilled in the art can make many possible variations and modifications to the disclosed embodiments, or equivalent modifications, without departing from the spirit and scope of the invention, using the methods and techniques disclosed above. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention.
