Blueberry screening machine capable of automatic feeding

Abstract

The invention discloses a blueberry screening machine capable of automatic feeding. The blueberry screening machine comprises a screening machine body and a feeding device; a screen plate is arranged in an inclined manner; a plurality of inclined grooves are transversely arranged formed on in the screen plate; the width of each groove is arranged to be 8-15 mm, and increases gradually from the higher end to the lower end of the screen plate; a first baffle and a second baffle are vertically arranged at the upper parts of the both sides of the screen plate; receiver plates are arranged on one side of the screen plate; the feed inlets of the receiver plates are corresponding to the lower ends of the grooves; a third baffle is arranged on the lower-end side of the screen plate; the feed inlets of the receiver plates are larger than the discharge openings of the receiver plates; baffles are arranged on both sides of each receiver plate; a plurality of receiver plates are sequentially arranged on one side of the screen plate; blueberries enter the screen plate through a conveyor belt and are enabled to roll towards the lower end of the screen plate through the cooperation of the screen plate and the grooves; meanwhile, after the blueberries roll in the grooves with the sizes matched with the blueberries, the blueberries move towards the lower ends of the grooves and finally enter the receiver plates; the mechanical screening and cleaning of the blueberries are is realized, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical screening machine, in particular to an automatic feeding blueberry screening machine. Background technique [0002] One type of blueberry is a low shrub, wild with short legs, small particles, and rich in anthocyanins; the second type is artificially cultivated blueberries, which can grow to 240cm in height, with larger fruits, more water, and relatively low anthocyanin content. There are more than 400 species of Vaccinium distributed all over the world. It originates in and is mainly produced in the United States and is also known as American blueberry. Wild blueberries in my country are mainly produced in the forest areas of Changbai Mountain, Daxinganling and Xiaoxinganling. It has only been successfully domesticated and cultivated in recent years. Research on blueberries in my country began in the early 1980s. The Small Berry Research Institute of Jilin Agricultural University took the lead in entering the fi...

Problems solved by technology

Since blueberries are now intensively planted, it is time-consuming and laborious to pick and screen, especially in the screening, manual screening is traditionally used, but the efficiency of manual screening is low, and it is difficult to avoid inaccurate manual screening
