Description

Technical Field

[0001] The utility model relates to the technical field of tea sorting mechanisms, and specifically, to a multi-stage sorting mechanism for tea. Background Technique

[0002] In the production and processing process of tea, sorting is an indispensable and important step. Traditional tea sorting mostly relies on manual operation, which is not only inefficient but also difficult to ensure the accuracy and consistency of sorting. With the progress of technology and the wide application of automation technology, currently, mechanized sorting mechanisms are usually used to complete tea sorting operations. There are many types of sorting mechanisms on the market, and most of them have the function of multi-stage sorting. This type of multi-stage sorting mechanism can screen tea into various size categories.

[0003] However, when most sorting mechanisms perform sorting operations, they generally use a spiral feeder for feeding. However, when using a spiral feeder for feeding, since the conveying method is forward pushing, it is easy for the conveyed tea to accumulate together during this process. When the tea accumulates together and is squeezed, it will affect the appearance and quality of the tea, damage the quality of the tea, and bring inconvenience to users. In view of this, we have proposed a multi-stage sorting mechanism for tea. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-stage sorting mechanism for tea to solve the defects proposed in the above background technique.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a multi-stage sorting mechanism for tea leaves, including a conveyor cylinder 1. A first mesh cylinder 10 is provided on the rear end part of the conveyor cylinder 1, and a second mesh cylinder 11 is provided on the front end part of the conveyor cylinder 1. The conveyor cylinder 1, the first mesh cylinder 10, and the second mesh cylinder 11 are integrally formed structures. The first mesh cylinder 10 and the second mesh cylinder 11 are mesh-shaped cylinder structures. The aperture of the through hole in the first mesh cylinder 10 is smaller than the aperture of the through hole in the second mesh cylinder 11, which is used for sorting operations from the back to the front;

[0026] Specifically, a spiral feeding ring 12 is fixedly installed on the inner wall of the conveyor cylinder 1. The spiral feeding ring 12 is spiral-shaped, and the rotation of the spiral feeding ring 12 is used for the forward conveying operation of the material;

[0027] Specifically, a gear ring 18 is fixedly installed on the barrel of the conveying cylinder 1. The gear ring 18 is a ring body with teeth on its annular side. A support base 14 is arranged at the bottom of the conveying cylinder 1. Two symmetrically arranged support rings 13 are fixedly installed on the support base 14. The conveying cylinder 1 passes through the support rings 13 and is rotatably connected to the support rings 13. A driving motor 19 is arranged on one side of the conveying cylinder 1. A gear 191 is fixedly installed at the end of the output shaft of the driving motor 19. The gear 191 meshes with the gear ring 18 to drive the conveying cylinder 1 to complete the rotation operation. An inlet cylinder 2 is arranged at the inlet end of the conveying cylinder 1. An inclined cylinder 20 is fixedly installed at the bottom end of the inlet cylinder 2. An inlet hopper 21 is fixedly installed at the top end of the inlet cylinder 2. A blower 23 is arranged at the rear end of the inclined cylinder 20. The inclined cylinder 20 is inserted into the inner cylinder of the inlet end of the conveying cylinder 1 to realize blowing the tea leaves into the first mesh cylinder 10 by the blower 23.

[0028] In this embodiment, the inclined cylinder 20 is arranged to be inclined downward at an angle of 45° to 60°. The end of the inclined cylinder 20 is inserted into the position of the first mesh cylinder 10, which is convenient for conveying the tea leaves to the position of the first mesh cylinder 10 for sorting operation.

[0029] Specifically, a rear end plate 22 is fixedly installed on the side of the rear end of the inclined cylinder 20 through a plurality of fastening screws. The blower 23 is fixedly installed on the rear end plate 22 to realize the support operation.

[0030] Furthermore, two symmetrically arranged first discharge hoppers 15 are fixedly installed on the support base 14. The two first discharge hoppers 15 are respectively located below the first mesh cylinder 10 and the second mesh cylinder 11 to realize the discharging operation.

[0031] In addition, a support rod 16 is fixedly installed on the side of one of the first discharge hoppers 15. A top plate 161 is fixedly installed at the top end of the support rod 16. The driving motor 19 is fixedly installed on the top plate 161.

[0032] It should be noted that a second discharge hopper 17 is fixedly installed on the side of the support base 14. The second discharge hopper 17 is located at the discharge end of the conveying cylinder 1.

[0033] When the multi-stage sorting mechanism for tea leaves of the present utility model is in use, tea leaves are put into the feeding hopper 21, and the tea leaves can fall out along the feeding cylinder 2 and the inclined cylinder 20 to the position of the first mesh cylinder 10. In addition, the blower 23 is connected to an external power source and made to work. When the blower 23 works, it can make the tea leaves be blown out more smoothly. In addition, the driving motor 19 is connected to an external power source and made to work. When the driving motor 19 works, the output shaft thereon rotates to drive the gear 191 to rotate. Since the gear 191 meshes with the gear ring 18, it can drive the conveying cylinder 1 to rotate. The rotation of the conveying cylinder 1 drives the spiral feeding ring 12 to rotate, so as to convey the tea leaves forward. During the forward conveying process, the tea leaves that meet the through-hole sizes in the first mesh cylinder 10 and the second mesh cylinder 11 can fall down into the first discharge hopper 15, and the other tea leaves fall out from the end of the conveying cylinder 1 to the second discharge hopper 17 for discharging operation, thus completing the multi-stage sorting operation.
