Efficient longan screening device

Abstract

The invention discloses an efficient longan screening device. The efficient longan screening device comprises a feeding device, a first screening device body, an outer shell, a second screening device body and universal wheels. A screen is arranged in the mode that one end of the screen is smaller than the other end of the screen. The first screening device body is arranged on the right side of the feeding device and arranged on the upper portion of the interior of the outer shell. A litchi inlet is formed in the right side of the second screening device body, and the right side of the second screening device body is fixedly connected with a semicircular slope baffle through a supporting rotation device. By arranging the screen of the screening device in the mode that one end of the screen is smaller than the other end of the screen, litchis are in a moving state; by arranging the screen and an external gear of the screening device, a transmission device is used for driving the external gear to rotate, and the screen is driven to rotate, so that the screening speed is increased; and by arranging the first screening device body and the second screening device body, the multiple-time screening function of the litchis is achieved, and the litchis of different types can be screened out.

Description

technical field [0001] The invention relates to a screening device, in particular to a high-efficiency longan screening device. Background technique [0002] Litchi is native to southern China. It is a subtropical fruit tree, an evergreen tree, about 10 meters high. The peel has scaly protrusions, bright red and purple red. , into the heart, spleen, and liver meridians; it can stop hiccups and diarrhea, and is a good food therapy product for intractable hiccups and diarrhea at dawn. Size grading mainly relies on manual sorting, which not only has long working hours and high labor intensity, but also cannot ensure the same size of lychees sorted by the same grade, which affects the sorting accuracy; although there are many existing fruit grading machines, for example, apples, citrus And other fruit grading machines, because the gap between the rollers is too large, it is not suitable for lychee grading; with the progress of society, people's living standards continue to impr...
