Description

Technical Field

[0001] The utility model belongs to the technical field of tea production equipment, and in particular relates to a tea wind selection and impurity removal device. Background Art

[0002] The working principle of the tea leaf air separation and impurity removal device is mainly to separate tea leaves and impurities through air separation; light impurities are blown away by air flow. This process utilizes the fact that tea leaves with different internal qualities have different aerodynamic properties, and their drift distances are different under the action of wind.

[0003] However, when the existing air separation and impurity removal device is in use, the tea leaves are usually transported directly to the air separation box through a conveyor belt during feeding. When transported to the air separation box, the tea leaves tend to accumulate into clumps, so that when the tea leaves enter the air separation box, the airflow has a poor effect on the air separation of the accumulated tea leaves, affecting the overall air separation quality of the tea leaves. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a tea air sorting and impurity removal device, which effectively solves the problem that the existing tea leaves are easily piled up in the process of entering the air sorting box.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tea air-sorting and impurity-removing device, comprising an air-sorting box, on which a feeding structure is provided; one end of the air-sorting box is also provided with a fan, the other end of the air-sorting box is provided with an impurity outlet, and a plurality of outlets are sequentially provided at the bottom of the air-sorting box; the feeding structure comprises a material mixing barrel connected to the air-sorting box, on which a feeding barrel is fixedly connected; a breaking shaft rotatably connected to the material mixing barrel, on which breaking rods are evenly distributed; a shaking plate rotatably connected to the air-sorting box is provided below the material mixing barrel, and partitions are evenly distributed on the shaking plate.

[0006] Furthermore, a scattering motor is fixedly connected to the material mixing barrel, and an output end of the scattering motor is coaxially fixedly connected to a scattering shaft.

[0007] Furthermore, a transmission chamber is fixedly connected to the air separation box, a shaking motor is fixedly connected to the transmission chamber, and an output end of the shaking motor is connected to a swing component connected to the shaking plate.

[0008] Furthermore, the swing assembly includes a crank fixedly connected to the output end of the shaking motor, and a connecting rod is rotatably connected to the crank; a rocker is rotatably connected to the connecting rod, and the rocker is coaxially fixed to the shaking plate.

[0009] Furthermore, a fan-shaped cylinder is fixedly connected in the air separation box, a fan-shaped rod is slidably connected to the fan-shaped cylinder, and the fan-shaped rod is fixedly connected to the shaking plate.

[0010] Furthermore, a plurality of air distribution plates corresponding to the plurality of discharge ports are evenly distributed in the air separation box.

[0011] Furthermore, the air separation box is provided with a plurality of observation windows.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is in use, the scattering motor drives the scattering shaft to rotate, so that the scattering shaft scatters the clumped tea leaves through the scattering rod, so that the tea leaves are scattered and fall onto a shaking plate in the air separation box, and the tea leaves are separated by the partitions on the shaking plate, so that the tea leaves fall evenly into the air separation box during the reciprocating swing of the shaking plate, so as to improve the uniformity of the air separation of the tea leaves.
