Broken black tea hammering cutting and stem picking device

Abstract

The invention provides a broken black tea hammering cutting and stem picking device, which comprises a hammering cutting machine, a stem picking machine and a material collecting cabin, wherein the hammering cutting machine comprises a lower casing and an upper casing, wherein a material hammering cutting cavity is formed between the upper casing and the lower casing; a first rotating shaft is arranged in the material hammering cutting cavity; a hammering cutting cutter group is arranged on the first rotating shaft; a feeding opening is formed in the top surface of the upper casing; a discharging opening is formed in the front end of the upper casing; the material feeding opening and the material discharging opening are respectively positioned at the two ends of the material hammering and cutting cavity; a powder material inlet is arranged on the material collecting cabin in a way of corresponding to the discharging opening; a discharging guiding passage is arranged between the powder material inlet and the discharging opening; a discharging hopper is arranged at the bottom of the material collecting cabin; a first material collecting hopper is arranged under the discharging hopper; a belt wheel conveying device is arranged under the first material collecting hopper; the stem picking machine comprises a cylindrical framework and a sieve screen; a second rotating shaft is arranged in the center of the cylindrical framework; one end of the second rotating shaft is provided with a rotating support mechanism; the other end of the second rotating shaft is provided with a guide support mechanism and a movable support mechanism; the discharging end of the belt wheel conveying device extends into the sieve screen arranged near one end of the rotating support mechanism.

Description

technical field [0001] The invention belongs to the technical field of red crushed tea production equipment, in particular to a device for hammering and sorting red crushed tea stems. Background technique [0002] Broken red tea is a bulk product in the international tea market, currently accounts for about 80% of the world's total tea export volume, and has a production history of more than 100 years, while it has been developed in my country for nearly 30 years. In the production process of crushed red tea, it is first necessary to chop the cooled and withered tea leaves for the first time, and then remove the tea stems contained therein. Although the existing hammer cutting machine can meet the requirements of use to a certain extent, it still has the disadvantages of uneven particle size and troublesome cleaning and maintenance. And in the prior art, large-scale enterprises generally use electrostatic stem sorting machines to remove tea stems in broken tea, but electros...

AI Technical Summary

Problems solved by technology

Although the existing hammer cutting machine can meet the requirements of use to a certain extent, it still has the disadvantages of uneven particle size and troublesome cleaning and maintenance.

Moreover, in the prior art, large-scale enterprises generally use electrostatic stem sorting machines to remove tea stems from broken tea, but electrostatic stem sorting machines have the problems of large investment and high cost

For small enterprises, ordinary sieves are generally used for screening, which has the problems of low work efficiency and unclean removal of tea stems.

[0003] In addition, in the existing equipment, after the hammer-cutting of tea leaves, the tea leaves are usually packed in containers and then manually transferred to the stem sorting equipment, which not only takes time and effort, but also reduces production efficiency
