Automatic sorting device and method for agricultural products

Abstract

The invention relates to the technical field of agricultural product sorting, and particularly relates to an automatic sorting device for agricultural products. The invention further relates to an implementation method of the automatic sorting device for the agricultural products. The automatic sorting device comprises a control unit, a feeding conveyor, a plurality of discharging conveyors and a horizontal material moving mechanism arranged between the feeding conveyor and the multiple discharging conveyors. The automatic sorting device is characterized by further comprising an overturning box, a material bearing rotating mechanism, a shooting head, a weighing mechanism and an illuminating mechanism, wherein the overturning box is arranged on the horizontal material moving mechanism in an overturning manner, a feeding opening and a discharging opening are formed in the overturning box, and material baffles capable of moving up and down are arranged on the feeding opening and the discharging opening; and the material bearing rotating mechanism, the shooting head, the weighing mechanism and the illuminating mechanism are arranged in the overturning box, and the material bearing rotating mechanism comprises a first roller and a second roller which are arranged in the overturning box in parallel. By means of the device, influences of light source light leakage and ambient light on fruit and vegetable spectrum detection are effectively reduced, the agricultural products can be overturned through the material bearing rotating mechanism, the shooting range is enlarged, and the sorting precision is improved.

Description

technical field [0001] The invention relates to the technical field of sorting agricultural products, in particular to an automatic sorting device for agricultural products. The invention also relates to an implementation method of the automatic sorting device for agricultural products. Background technique [0002] Agricultural products are items produced in agriculture, such as peanuts, corn, melons and fruits, etc., whose individual shape and size often determine the price of agricultural products. sorting. [0003] Patent application number CN201810282954.4 discloses an automatic sorting device for agricultural products and its control method. Before sorting agricultural products, the left and right limiting plates are moved according to the dimensions of the agricultural products to be sorted, so that the left The width between the limit plate and the right limit plate is just enough to pass a single agricultural product to be sorted, ensuring that the agricultural pr...

[0003] Patent application number CN201810282954.4 discloses an automatic sorting device for agricultural products and its control method. Before sorting agricultural products, the left and right limiting plates are moved according to the dimensions of the agricultural products to be sorted, so that the left The width between the limit plate and the right limit plate is just enough to pass a single agricultural product to be sorted, ensuring that the agricultural products are transmitted one by one, avoiding multiple overlapping, and the agricultural products are stable on the conveyor belt during the whole process of sorting Transmission ensures the integrity of soft agricultural products and avoids secondary damage to multi-quality soft agricultural products. This application can automatically sort different agricultural products, but during sorting, due to external influences, the detection light will have The influence of deviation, light leakage of light source and ambient light on the spectral detection of fruits and vegetables leads to low detection accuracy and affects the sorting accuracy. Therefore, we propose an automatic sorting device for agricultural products in order to solve the problems raised above.
