Description
Technical Field
The utility model belongs to the technical field of tea processing equipment, and relates to a tea screening device.
Background
In the existing mode, the tea screening is usually carried out by adopting a vibration screening machine, namely a multi-layer screen structure, whether the tea is single-bud, one-bud and one-leaf, one-bud and multi-leaf or silver needle, the screen is easy to be blocked, especially, the tea with buds and leaves is difficult to disperse out of holes through vibration after the tea with buds and leaves is clamped into the filtering holes of the screen, the blocking surface is large, and the bud and leaf structure of the tea can be damaged.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a tea screening device, and the technical problem to be solved by the utility model is how to avoid screen blockage.
The aim of the utility model can be achieved by the following technical scheme: the tea screening device is characterized by comprising a frame, two rotating wheels and a transmission belt connected end to end, wherein the contact surface of the rotating wheels and the transmission belt is elliptical, an inclination angle of 80-100 degrees is formed between long axes of the two rotating wheels, the transmission belt comprises two annular toothed belts and a filter screen positioned between the two toothed belts, and the rotating wheels are provided with outer tooth rings meshed with the toothed belts; a receiving plate is arranged between the two straight sections of the transmission belt.
Further, the filter screen is a multi-section structure, and a division bar for connecting two toothed belts is arranged between sections of adjacent filter screens.
After the filter screen rotates to the position below the lowest straight section, the reverse cleaning of the filter screen can be realized so as to clean tea leaves blocking the filter screen and large-size tea leaves failing to pass through the filter screen, and the tea leaves filtered by the filter screen are collected at the material receiving plate.
One of the rotating wheels is driven by the motor to rotate at a constant speed, and the rotating wheels are of a non-circular structure, so that the filter screen can be in a shaking state to realize vibration of tea leaves, and meanwhile, the vibration can also enable the filter screen to be cleaned reversely when the feeding surface is downward, so that tea leaves blocking the filter holes are removed.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
The tea screening device shown in the figures 1-3 comprises a frame 1, two rotating wheels 2 and a driving belt 3 which are connected end to end, wherein the contact surface of the rotating wheels 2 and the driving belt 3 is elliptical, the long axes of the two rotating wheels 2 form an inclination angle of 80-100 degrees, the driving belt 3 comprises two annular toothed belts 8 and a filter screen 4 positioned between the two toothed belts 8, and the rotating wheels 2 are provided with an outer gear ring 5 meshed with the toothed belts 8; a receiving plate 6 is arranged between two straight sections of the driving belt 3.
The filter screen 4 is of a multi-section structure, and partition strips 7 for connecting two toothed belts 8 are arranged between sections of adjacent filter screens 4; the parting bead 7 not only can keep the shape of the two toothed belts 8, but also can divide the filter screen into a plurality of blocks.
In the rotating process of the rotating wheels, the toothed belt can have a certain tension change, but the two rotating wheels basically have a 90-degree phase difference due to the adoption of a tooth meshing mode, and the transmission belt cannot be separated from the meshing of the outer gear ring.
After the filter screen 4 rotates to the position below the lowest straight section, the reverse cleaning of the filter screen 4 can be realized to clean tea leaves blocking the filter screen 4 and large-size tea leaves which cannot pass through the filter screen 4, and the tea leaves filtered by the filter screen 4 are collected at the material receiving plate 6.
One of the rotating wheels 2 is driven by a motor to rotate at a constant speed, and the rotating wheel 2 is of a non-circular structure, so that the filter screen 4 can be in a shaking state to realize vibration of tea leaves, and meanwhile, the vibration can also enable the filter screen 4 to clean reversely when the feeding surface is downward, so that tea leaves blocking the filter holes are removed.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
