Embodiment 1

[0025] Such as Figure 1-8 As shown, the pearl screening device of the present embodiment 1 includes a sphericity screening driving device 2, and the sphericity screening driving device 2 drives and connects the crank rocker mechanism (one) 3, and the crank rocker mechanism (one) 3 is arranged on the fixed plate 4 On the top, the crank rocker mechanism (1) 3 drives the pearl sphericity screening cup 1 to move on an elliptical trajectory; the pearl sphericity screening cup 1 is in the shape of a round table, and the wall of the pearl sphericity screening cup 1 is provided with a plurality of ovals of the same size. The holes 5, wherein the elliptical holes 5 are longitudinal elliptical holes, are evenly distributed in the middle and upper end of the cup wall of the pearl sphericity screening cup 1.

[0026] The inner surface of the pearl sphericity screening cup 1 is smooth, so as to reduce the friction of the pearl fish pearl sphericity screening cup 1 and reduce the wear on t...

Abstract

The invention discloses a pearl screening device which comprises a sphericity screening drive device, wherein the sphericity screening drive device is in driving connection to a crank rocker mechanism (I) which is arranged on a fixed plate, and drives a pearl sphericity screening cup to carry out elliptical-orbit motion; the pearl screening device is further provided with a pearl feeding device; the pearl sphericity screening cup is in the shape of an inverted circular table; and a plurality of elliptic holes which are the same in size are formed in the cup wall of the pearl sphericity screening cup. The pearl screening device disclosed by the invention is simple in structure and is simple and convenient to operate; the screening drive device selects a motor as a power source, so that pearls can be quickly screened according to the sphericity and the size, and therefore, the working efficiency is improved, and the problems that the pearl sphericity sorting efficiency is low, and the pearl shape screening is not qualified are solved.

Description

technical field [0001] Technical field: the present invention relates to the technical field of screening devices, in particular to a pearl screening device. Background technique [0002] The pearl industry is a traditional characteristic industry in my country. In recent years, the annual output of pearls in my country has reached more than 2,000 tons. Pearls have different shapes, and different shapes have different values. In fact, various applications require pearls of different grades. Therefore, in the process of processing, it is necessary to classify the shape of the pearl sphericity. At present, my country's freshwater pearl production accounts for 95% of the world's total production. The number of pearl deep-processing enterprises is small and the scale is small. At present, my country's pearl production enterprises basically use the traditional manual preferred method to carefully screen, which consumes a lot of manpower and time. The efficiency is low, and the ac...
