Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea refining shaking and screening machine with a feed regulating structure. Background Art

[0002] After tea leaves are roasted and dried, in order to make the shape and size of the tea leaves more consistent, they need to be screened to obtain tea leaves of different grades. Tea shaking and screening machines are the most commonly used screening machines. They have the advantages of high screening efficiency and easy operation. The existing tea shaking and screening machines include a frame, a screen frame, a drive assembly and a screen.

[0003] After searching, a Chinese patent with announcement number CN211003456U discloses a feed adjustment structure for a tea shaking and screening machine, including a tea shaking and screening machine body, and a baffle connected between the bottom end of the second fixed plate and the outlet. The beneficial effects are: such a device has a simple structure and is easy to use, and can effectively adjust the flow rate of tea leaves as needed to avoid excessive tea leaves and affect the screening effect.

[0004] After searching, a Chinese patent with announcement number CN205253541U discloses a feeding adjustment structure of a tea sifting machine, including a frame, a sifting body arranged on the frame, and a driving assembly for driving the sifting body to move; the sifting body includes a sieve frame. The utility model can effectively control the amount of tea entering the sieve by arranging a feed chute partition in front of the sieve, so that the tea enters the sieve evenly, and the partition can be adjusted to control the amount of tea entering the sieve per unit time, which can be widely used in the field of tea sifting machines.

[0005] Although the above scheme can adjust the flow rate of tea leaves as needed, the feed adjustment structure of the tea shaking and screening machine in the above patent does not have the function of clearing the accumulated tea leaves while reducing the tea feeding speed. When the tea feed of the above tea shaking and screening machine is large and the discharge speed is slow, the tea leaves are easily accumulated at the feed port, and after the stirring device is installed, the stirring device keeps rotating, affecting the normal feeding of the shaking and screening machine. For this reason, we provide a tea refining shaking and screening machine with a feed adjustment structure to solve the above problems. Utility Model Content
