Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tea sorting, in particular to a tea sorting machine. BACKGROUND

[0002] In the tea processing process, tea sorting is one of the key steps to ensure the consistency of tea quality, and the traditional tea sorting method is mostly manual operation, which selects tea leaves of different sizes and weights through artificial visual inspection and hand feeling, or selects the size of tea leaves through a screen, and divides the screened tea leaves into secondary, intermediate and special grades by using screen meshes of different levels; although the screening method saves human resources to some extent, it cannot simply rely on the screen to determine the grade of tea in actual use, because the screen can only screen the size of tea leaves, and the grade of tea is related to not only the size of leaves but also the weight of tea, so the tea with large leaves but light weight does not have the best taste when brewing.

[0003] Therefore, we need a tea sorting machine that can sort tea according to both the size of leaves and the weight of tea. SUMMARY

[0004] The utility model wants to solve the problem of providing a tea sorting machine to improve the problems in the prior art.

[0005] The technical scheme provided by the utility model to solve the above problems is a tea sorting machine, which comprises a support frame, a hopper mounted on the support frame, a screen rotatably connected to the support frame, a fan mounted on the support frame for screening tea, a transmission plate connected to the support frame, and the transmission plate located below the screen.

[0006] More preferably, the side of the screen close to the hopper is connected with an inclined plate, and the inclined plate is used to receive the tea falling from the hopper.

[0007] More preferably, the fan is located below the screen and above the transmission plate, and there is a vertical space between the fan and the screen for tea falling.

[0008] More preferably, a collection frame is mounted on the support frame, the collection frame is located in the vertical space between the fan and the screen, and the top of the collection frame is flush with the side of the transmission plate close to the fan.

[0009] More preferably, a gas cylinder is mounted on the side wall of the support frame, the telescopic end of the gas cylinder is in contact with the screen, and the gas cylinder is used to drive the screen to swing.

[0010] More preferably, a baffle is slidably connected to the bottom of the barrel, the baffle is used to block the falling of the material in the barrel, an electric push rod is installed on the side wall of the barrel, and the telescopic end of the electric push rod is connected with the baffle.

[0011] More preferably, a gravity sensor is installed on the screen, and the gravity sensor is electrically connected with the electric push rod.

[0012] Compared with the prior art, the utility model has the advantages that: the screen and the fan are matched, the screen can screen out tea leaves with small blades, and the fan can blow tea leaves with large blades but insufficient quality, so that the tea leaves falling into the collecting frame are qualified in terms of blade size and quality, and the gravity sensor and the electric push rod are matched, so that when the screening burden on the screen is heavy, the baffle blocks the opening of the barrel, so that no new tea leaves fall onto the screen, thereby reducing the screening burden of the screen and ensuring the screening quality.
