Tea leaf screening device

Abstract

The invention provides a tea leaf screening device which comprises a machine frame, a feeding hopper, an anti-blockage mechanism and screening mechanisms. The anti-blockage mechanism comprises lineardriving mechanisms, a connection plate, a supporting frame, an ejector pin plate and ejector pins. Two of the three linear driving mechanisms are installed on the two sides of the machine frame correspondingly, the two ends of the connection plate are installed on the two linear driving mechanisms located on the two sides of the machine frame correspondingly, the linear driving mechanism not installed on the machine frame is installed on the connection plate through a bolt, the ejector pin plate is installed on the linear driving mechanism located on the connection plate through a supporting frame, and the multiple screening mechanisms are installed inside the machine frame at equal intervals. Screening boxes are driven by rotating air cylinders to swing back and forth, baffles seal the screening boxes in the swing process of the screening boxes, therefore, tea leaves can be screened for a long time in the screening boxes, the screening effect is improved, the linear driving mechanismsdrive the ejector pin plates to dredge screening holes in the screening boxes, and the condition that the screening holes are blocked by tea leaves to affect screening efficiency is avoided.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea screening device. Background technique [0002] Drinking tea is not only a traditional food culture, but at the same time, because tea contains a variety of antioxidant substances and antioxidant nutrients, it has a certain effect on eliminating free radicals. Therefore, drinking tea is also helpful for anti-aging, and has the function of health care. Drinking two to three cups of tea a day can play a role in anti-aging. Tea contains a variety of vitamins and amino acids. Drinking tea also has a certain effect on clearing oil and degreasing, enhancing nerve excitement, digestion and diuresis. In the process of tea production, since the collected tea leaves are different in size and shape, the grades of the finished products are also different, so the tea leaves must be screened before production. [0003] Publication No. CN108097577A provides a space cam type three...

AI Technical Summary

Problems solved by technology

[0003] Publication No. CN108097577A provides a space cam type three-degree-of-freedom vibrating screen. This device drives the screen box to swing through the driving device to achieve screening, but this device only screens materials through one screen box, and then when multi-stage screening is required Materials cannot be screened with this device, and anti-clogging treatment cannot be performed during the screening process

[0004] Publication No. CN207787013U provides a special tea screening device for tea planting. This device can prevent the sieve holes on the screening cylinder from clogging through the air jet device and ensure the screening effect. The time of the sieve hole is short so there is no guarantee that the sieve hole will be dredged completely
