[0002] The essence of a tea screening device based on wind force is to use wind force to "fan the tea" and classify the tea according to its weight. Generally, wind force is introduced on one side of the tea inlet, and the wind force can blow towards the incoming tea. Since the quality of tea with different degrees of integrity is different, the distance that the tea is blown out is different, realizing multi-level screening of the tea. In the prior art, in order to solve the problem of tea agglomeration, a vibrating hopper is generally arranged at the inlet to force the tea to disperse, so as to facilitate "fanning the tea".

Detailed Embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0027] In view of the problem in the prior art that tea leaves agglomerate and are not conducive to "fanning tea", the present application provides a swingable hopper to force the tea leaves to disperse, so as to facilitate "fanning tea".

[0028] Figure 1 Fig. shows a schematic diagram of the overall structure of a tea screening device based on wind force; Figure 2 Fig. shows a schematic diagram of the internal structure of a tea screening device based on wind force; Figure 1 and Figure 2 In [relevant figure], the tea screening device based on wind force includes a housing 100, a feed inlet 110 opened at the top of the housing 100, and an air inlet 120 opened on one side of the housing 100 and corresponding to the feed inlet 110. A plurality of groups of partition plates 130 are arranged at intervals along the wind direction in the housing 100, dividing the bottom of the housing 100 into multiple different areas. After the feed inlet 110 feeds the tea leaves, the air inlet 120 introduces strong wind and outputs it towards the tea leaves, causing tea leaves of different qualities to fall into different areas divided by the partition plates 130, so as to realize the screening and grading of the tea leaves.

[0029] Figure 3 Fig. shows a schematic diagram of the structure of the swing mechanism 200; Figure 4 Fig. shows Figure 3Schematic diagram of the state structure; a swing mechanism 200 corresponding to the feed inlet 110 is arranged in the housing 100. The swing mechanism 200 includes a fixed shaft 210 and a hopper 220 rotatably connected outside the fixed shaft 210. The fixed shaft 210 is connected to the inner wall of the housing 100. A slideway 221 is formed on the side wall of the hopper 220. The inner wall of the housing 100 is rotatably connected with a drive shaft 230, and the other end of the drive shaft 230 is connected with a crank 240. The other end of the crank 240 is connected with a drive rod 250, and the drive rod 250 is slidably arranged in the slideway 221. When the drive shaft 230 is driven by an external force, it can drive the drive shaft 230, the crank 240 and the drive rod 250 to rotate around the drive shaft 230, so as to drive the hopper 220 to rotate reciprocally around the fixed shaft 210 to realize swinging. The drive shaft 230 and the drive rod 250 are staggered on the vertical projection plane of the crank 240. That is to say, the drive shaft 230 and the drive rod 250 are not on the same axis. When the drive shaft 230 rotates self, it will force the drive rod 250 to revolve around the drive shaft 230. In this application, the swinging of the hopper 220 is used to force the tea leaves to disperse, so as to facilitate the subsequent "tea fanning". One end surface of the hopper 220 facing the feed inlet 110 has a material cavity 222, and one side of the material cavity 222 extends along the advancing direction of the tea leaves and forms an opening. Through the arrangement of the material cavity 222, it can be avoided that the tea leaves fall from other directions during the swinging process of the hopper 220. When the hopper 220 is in the horizontal state, the drive rod 250 moves to the highest point. That is to say, the swinging of the hopper 220 only occurs below the horizontal state. By limiting the swinging range of the hopper 220, it can be avoided that the tea leaves on the surface of the hopper 220 interfere with the falling tea leaves when the hopper 220 swings upward.
