Tea sifting and grading machine

Abstract

The invention discloses a tea sifting and grading machine and relates to the technical field of tea processing. The tea sifting and grading machine comprises a box. An opening is formed in the lower end of the box. A plurality of oblique guiding plates are arranged at the opening at equal intervals. A feed inlet is formed in the upper end of the box, and a feed hopper is arranged at the feed inlet. The feed hopper comprises a fixed component and a movable component, and the fixed component is fixedly mounted on the box while the movable component is inserted into the fixed component. A mounting rack is fixedly arranged on the box. A drive motor is fixedly mounted on the mounting rack. An eccentric wheel is connected to a rotary shaft of the drive motor and connected with the movable component through a connecting rod. An air inlet pipeline is further arranged on the box and provided with an air blower in a connected mode. According to the tea sifting and grading machine, materials are fed uniformly, and the sifting and grading effects are good.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea screening machine. Background technique [0002] Sieving of tea leaves is an essential step in the processing process, especially after picking fresh tea leaves, which contain some small broken leaves, which need to be sieved out in time, and the broken leaves can be used for other tea leaves Processing, such as making tea cakes, tea bags and other products after grinding. And because the tea leaves are large and small, in order to facilitate the unification of shape and appearance in the later stage of rolling, it is also necessary to sieve them by size. [0003] The sieving of tea can be divided into manual sieving and mechanical sieving now. Manual sieving has low efficiency and high labor cost and has been gradually eliminated. Now it is generally sieved by machinery, as disclosed in Chinese patent CN201420175050.9 A screening machine for tea, comprising a siev...

AI Technical Summary

Problems solved by technology

But there are following problems: 1. It is very inconvenient to use. After using for a certain period of time, a large number of larger tea leaves are piled up on the first filter screen to cover the sieve holes, and the efficiency of adding tea leaves to sieve is very low. At this time It is necessary to take out the tea leaves on the first filter screen to continue working, so the operation steps are increased. Similarly, after the tea leaves on the second filter screen have accumulated to a certain thickness, they must also be taken out, and the second filter screen is very difficult to take out , so the practicability is not strong, continuous operation is not possible, and the efficiency is not high

2. Tea leaves are easy to fall into the air inlet pipe under the second filter screen, which will damage the normal operation of the fan
