Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tea processing, in particular to a selenium-rich tea grading device. BACKGROUND

[0002] Selenium-rich tea refers to tea with a high selenium content, and is usually tea produced in selenium-rich areas. After color selection, tea can be separated according to different colors, and tea with different colors can be classified according to quality. However, tea with the same color still has different particle sizes, and if it is directly packaged and sold, the quality and price will be inevitably affected. Therefore, before the tea is packaged and delivered, the tea particles of different sizes need to be screened and separated to screen tea of different grades, and then the tea is classified and packaged for grading sales.

[0003] During the grading and screening of selenium-rich tea, the tea is mainly screened and graded by a screening machine. However, when the selenium-rich tea falls onto the screening net inside the screening machine, the selenium-rich tea is prone to pile up together, and the upper layer of selenium-rich tea is not easy to fall, which affects the thoroughness of the screening and grading of the selenium-rich tea and the quality of the selenium-rich tea.

[0008] When the selenium-rich tea falls onto the top of the filter screen, the connecting rod drives the filter screen to rotate through the support plate. When the filter screen rotates, it can drive the selenium-rich tea to rotate, so that the selenium-rich tea can be evenly spread on the filter screen, and the selenium-rich tea can be comprehensively screened and graded, thereby improving the quality of the selenium-rich tea.

[0009] Preferably, the scraping mechanism comprises a connecting frame, a connecting plate and a separation rod, one end of the connecting frame is welded to the inner side of the screening box, the other end of the connecting frame is welded to the top of the connecting plate, and a plurality of groups of the separation rod are welded to the bottom of the connecting plate.

[0010] Preferably, the outer surface of the connecting rod is rotationally connected with a connecting sleeve, two groups of support rods are welded to the outer surface of the connecting sleeve, and one end of the support rod away from the connecting sleeve is welded to the inner surface of the screening box.

[0011] Preferably, the connecting frame is an L-shaped frame body.

[0012] Preferably, the connecting sleeve is connected with the connecting rod through a bearing.

[0013] Preferably, the three groups of support plates and the filter screens are equally spaced, and the discharge port is located at a position corresponding to the support plate on the outer side of the screening box.

[0014] Preferably, the mesh holes of the three groups of filter screens decrease from top to bottom.

[0015] In summary, the present application has at least one of the following beneficial effects:
