The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A tea processing multi-stage sorting mechanism, as shown in figures 1 to 3,

the automatic sorting device comprises a first-stage sorting unit and a second-stage sorting unit; first order letter sorting unit includes first cylinder 1, and this first cylinder slope is arranged, divide into the design of triplex, all is equipped with a plurality of sieve meshes on each part, specifically includes: the screening device is sequentially designed into a first screening section 2, a second screening section 3 with screen holes larger than the first screening section and a third screening section 4 with screen holes larger than the second screening section from top to bottom; the second-stage sorting unit comprises an outer roller 5 which is obliquely arranged and an inner roller 6 which is arranged on the inner side of the outer roller and has a sieve pore larger than that of the outer roller;

a first hopper 7 is arranged corresponding to the lower side of the first screening section, a second hopper 8 is arranged corresponding to the lower side of the second screening section, and a third hopper 9 is arranged corresponding to the lower side of the third screening section; a fourth hopper 10 for containing the screened objects in the outer roller is arranged corresponding to the lower side of the outer roller;

the screened materials in the second hopper are conveyed to an inner roller of the second sorting unit; the screened materials in the first hopper are directly conveyed to the inferior product storage tank 11, it is pointed out that each hopper can be directly arranged at the lower side to start a discharge hole, so that the materials are conveyed, and of course, the screened materials in each hopper can also be conveyed to a target area through a pipeline. Since the conveyance of the screen (tea leaves) downstream from the hopper belongs to the prior art, it is not described in much detail here.

The screened material discharged from the lower end of the outer roller returns to the first roller for sorting again or is conveyed to a medium product storage tank 12; the screened material in the third hopper and the screened material discharged from the lower end of the inner roller are directly conveyed to a fine product storage tank 13. Typically, a fifth hopper 17 may be provided at the lower end of the inner drum to receive the screened material.

It should be noted that the part of the upper end of the inner drum exposed out of the outer drum is not provided with sieve holes, only the part of the inner drum within the outer drum is provided with smaller sieve holes (for screening out the tea product with medium grade which is slightly inferior to the quality of the fine tea, the tea can return to the first drum for screening and sorting again, and the secondary tea product with adulterated therein or doped therein is screened out), and the part of the lower end of the inner drum extending out of the outer drum is provided with larger sieve holes (for screening out the fine tea).

Separating rings 14 are arranged between the first screening section and the second screening section, and between the second screening section and the third screening section in the first roller. Typically, the spacer ring has a height of 5-10 mm. The design of the separating ring is mainly to ensure that the tea leaves can have longer residence time in each screening section, the screening and sorting are more sufficient, and meanwhile, more tea leaves can be gathered in the screening sections to realize high-efficiency screening. Similar with first cylinder structure, above-mentioned outer cylinder and interior cylinder inner wall all are equipped with a plurality of baffles 15 that separate along the circumferencial direction, can effectual gathering tealeaves to realize abundant efficient screening and letter sorting.

Above-mentioned inner drum and outer cylinder are coaxial to be arranged, and outer cylinder both ends are seted up inner drum and can be worn to establish trompil wherein, can not produce the interference structurally.

In an alternative embodiment, the inner wall of the inner drum and the outer drum are provided with parabolic plates 16 along the circumferential direction, and the height of the parabolic plates is larger than that of the baffle plates. In an alternative embodiment, the parabolic plates are arranged on the inner wall surfaces of the outer drum and the inner drum in a V-shape, and the openings of the parabolic plates face to the upward side of the second sorting unit. Tea leaves rotate along with the roller, and in the process of moving towards the lower end, the tea leaves are blocked by the parabolic plate, and the tea leaves are temporarily located at the position above the parabolic plate in the moment, when the roller rotates to enable the parabolic plate at the lower side to gradually rotate to the upper side, the blocked tea leaves at the position of the parabolic plate can drop along the trend, equivalently, the tea leaves are thrown in the air, the tea leaves are scattered for multiple times, and the screened sorting effect is better.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
