Problems solved by technology

[0003] The existing pearl grading device has certain disadvantages in use. Firstly, when the pearl is grading, it will cause mutual abrasion of the pearls, which will affect the quality of the pearls and have certain adverse effects. Secondly, when the device is placed, it is necessary to It wastes a lot of time for the staff to adjust the stable placement of the device, which has certain adverse effects and has a certain impact on people's use process. For this reason, we propose a pearl grading device

Abstract

The invention discloses a pearl grading device. The pearl grading device comprises a grading sieving box, wherein a charge hopper and a vibration motor are arranged on the outer surface of the upper end of the grading sieving box; the vibration motor is located at one side of the charge hopper; an inner protection layer is arranged on the inner surface of the charge hopper; discharge doors are formed in the outer surfaces of the two sides of the grading sieving box separately; a transfer rotating rod is arranged on the outer surface of the lower end of the vibration motor; and a vibration transfer element is arranged on the outer surface of one side of the transfer rotating rod. According to the pearl grading device, a grading sieving structure and an adjustable support structure are arranged, and mutual wear among pearls can be effectively reduced during pearl grading treatment, so that the quality of the pearls is ensured, and people are benefited to use; and moreover, working personnel can be facilitated to rapidly and stably place according to the smoothness of the ground, so that the normal working of the device is ensured, people are benefited to use, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of pearl grading equipment, in particular to a pearl grading device. Background technique [0002] Pearl is a member of colored gemstones; because of its historical tradition and moderate price, it is deeply loved by Chinese people; in today's jewelry industry, especially jewelry e-commerce, pearls occupy an important position; however, the development of pearls still needs to be solved An important obstacle is how to quantitatively and systematically identify the authenticity and quality of pearls, which involves the formulation and implementation of pearl grading standards. [0003] The existing pearl grading device has certain disadvantages in use. Firstly, when the pearl is grading, it will cause mutual abrasion of the pearls, which will affect the quality of the pearls and have certain adverse effects. Secondly, when the device is placed, it is necessary to It wastes a lot of time for the staff to adjust the sta...
