Blueberry screening mechanism

Abstract

The invention discloses a blueberry screening mechanism. The blueberry screening mechanism comprises a screening plate and receiving pans, wherein the screening plate is obliquely arranged; a plurality of oblique grooves are laterally formed in the screening plate; the width of each of the grooves is set to 10-15mm, and the widths of the grooves are gradually increased along the screening plate from the higher end of the screening plate to the lower end of the screening plate; a first baffle and a second baffle are vertically arranged above two sides of the screening plate; the receiving pans are arranged on one side of the screening plate; feed openings of the receiving pans correspond to the lower ends of the grooves; a third baffle is arranged on one side of the lower end of the screening plate; the feed openings of the receiving pans are larger than discharge openings of the receiving pans; baffles are arranged on two sides of each of the receiving pans; the receiving pans are sequentially arranged on one side of the screening plate; when blueberries are put on the screening plate, through the cooperation of the oblique screening plate and the oblique grooves, the blueberries which enter the screening plate roll to the lower end of the screening plate, and besides, when the blueberries roll to the grooves of which the sizes are matched with those of the blueberries, the blueberries in the grooves move to the lower ends of the grooves, and then enter the receiving pans, so that the mechanical screening of the blueberries is realized, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical screening machine, in particular to a blueberry screening mechanism. 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 field of blueberry ...

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
