Multifunctional blueberry screening machine

Abstract

The invention discloses a multifunctional blueberry screening machine. The machine comprises a screening machine body and a feeding device, wherein the screening machine body comprises a screening plate, receiving plates, a vibration motor and multiple vibration springs uniformly distributed below the screening plate; the widths of grooves are 8-15 mm, and are gradually increased from high end to low end along the screening plate; blueberries are conveyed onto the screening plate from a feeding table through a conveying belt; the blueberries entering the screening plate roll to the lower end of the screening plate through the fit between the inclined screening plate and the inclined grooves; when the blueberries roll to the grooves with proper sizes, the blueberries move to the lower ends of the grooves in the grooves to enter the receiving plates; and when the blueberries roll on the screening plate and in the grooves, nozzles positioned rightly above the grooves continuously spray water downwards, and the water in a first baffle plate continuously flows downwards to wash the blueberries, so that the mechanical blueberry screening is realized, the screening efficiency is improved, and the blueberries are cleaned while screening.

Description

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

AI Technical Summary

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, and after screening Manual cleaning is required, which increases the workload
