Description

Technical Field

[0001] The utility model relates to the technical field of tea screening, in particular to screening equipment based on tea processing. Background Art

[0002] Tea leaves, commonly known as tea, are processed from the leaves and buds of the tea tree. Tea drinking originated in China and is a traditional beverage with a very long history. When tea leaves are processed, they need to be screened first so that larger leaves can be screened out. The commonly used method of screening tea leaves is generally to use a tea screening machine, which sets two layers of screens and then uses a vibration motor to drive the screen to vibrate, thereby screening out whole leaves and broken leaves, so as to facilitate further processing based on the integrity of the tea leaves.

[0003] The Chinese patent with publication number CN218014090U, a vibration screening device for tea processing, points out that after the tea is screened once, some smaller residues will be mixed in, and the screening effect of the tea is poor. The servo motor, the first gear, the rotating rod, the first eccentric wheel, the second eccentric wheel and the second screen plate are used in combination. The servo motor drives the first gear to rotate, so that the first gear drives the second gear and the first eccentric wheel to rotate. The first eccentric wheel rotates and the second screen plate is shaken up and down to perform the initial screening of the tea. The smaller residues can be screened out, solving the problem of the smaller residues. However, when using the vibration screening device to screen the tea, in order to screen the broken leaves, whole leaves and impurities in the tea, two groups of screens of different specifications are generally set to screen the tea. However, when the screen with smaller specifications is used to screen the tea, due to the smaller mesh, some broken leaves will be stuck in the mesh and block the mesh. The cleaning structure currently used generally directly pushes the entire screen to move. This dredging method is not effective when the edge is blocked. Therefore, a screening device based on tea processing is designed to solve the above-mentioned problems. Utility Model Content
