Detailed Description

For a better illustration of the present utility model, the following description is made with reference to the accompanying drawings and examples:

The utility model discloses a tea screening machine, which is shown in fig. 1-2, and comprises a base 1, wherein a fan mechanism 901 for providing wind power is arranged in the base 1, two baffles 5 with symmetrical front and rear positions are fixedly arranged on one side surface of the base 1, a top plate 6 is fixedly arranged at the upper end of each baffle 5, an opening 7 for pouring tea is arranged in the upper surface of the top plate 6, and a feeding mechanism 902 capable of uniformly and stably providing tea is arranged at the upper end of the base 1.

Further, the feeding mechanism 902 comprises two symmetrical fixing plates 15 fixedly arranged on the upper end face of the base 1, a rotating shaft 8 is rotatably connected between the fixing plates 15, belt wheels 12 are fixedly arranged on the rotating shaft 8, chain belts 9 are connected between the belt wheels 12, and a plurality of transportation grooves 11 for transporting tea are uniformly distributed on the chain belts 9 at equal intervals.

Further, a supporting plate 14 is fixedly arranged on the upper side of the fixing plate 15, and a feeding chute 10 is fixedly connected between the supporting plates 14.

Further, the bottom of the feed chute 10 is higher than the upper end surface of the transport chute 11.
