Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to an automatic feeding and discharging tea screening device. Background Technology

[0002] Tea generally consists of the leaves and buds of the tea plant. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health.

[0003] During tea production, tea leaves often contain small particles of impurities such as dust. Air classifiers sift through the tea leaves, vibrating them to shake the leaves and causing the dust and other impurities to float and be sucked away. However, the discharge end of the vibrating mechanism on typical air classifiers is unobstructed, which can lead to tea leaves being discharged directly from the discharge area due to inertia without any impurities being removed.

[0004] In view of this, we propose an automatic feeding and discharging tea sorting device. Utility Model Content

[0044] Example 2: An automatic feeding and discharging tea sorting device, see [link / reference] Figure 3 and Figure 4 ;

[0045] A limiting component 903 is arranged at the bottom of the baffle 901; the limiting component 903 includes a stop strip 9031; the stop strip 9031 is arranged at the bottom of the baffle 901; wherein, the bottom end of the stop strip 9031 is set as an inclined surface, and the bottom end of the stop strip 9031 contacts and engages with the lower bottom side of the vibrating bucket 2.

[0049] Working Principle: Using the device of this invention, tea leaves are automatically transported into the feeding channel 5 by a hoist. The tea leaves fall onto the vibrating bucket 2 along the inclined feeding channel 5. The vibrating motor body 4 drives the vibrating bucket 2 to vibrate. At this time, the baffle 901 is in a vertical position to block the material. The blower body 7 blows air upward into the inner cavity of the air chamber 6. Small particles such as dust emitted during vibration are sucked into the air chamber 6 and then sucked away from the air outlet 8. During discharge, the servo motor body 902 drives the baffle 901 to rotate outward until the rubber pad 9036 and rubber strip 9037 contact the bottom side of the lower end of the vibrating bucket 2 and then stop. The downward tilt of the baffle 901 does not affect the discharge of the tea leaves.
