Stem and leaf separating machine for mechanically picked fresh leaves

Abstract

The invention discloses a stem and leaf separating machine for mechanically picked fresh leaves. Lower feed plates are driven to rotate by a first rotating and driving mechanism so as to be butted with or separated from upper feed plates; inverted cone-shaped ports are formed at the tail ends of the lower feed plates, so that tea stem heads can stretch out of the inverted cone-shaped ports, and the whole tea leaves cannot slip off; a main shaft can be driven to flexibly run relative to a machine frame by a third rotating and driving mechanism; clamping mechanisms rotate with the main shaft, and when the clamping mechanisms are driven by a second rotating and driving mechanism, clamp plates at the tail ends of the clamping mechanisms are opened and closed; a leaf outlet groove can be driven by a reciprocating motion mechanism to make reciprocating linear motion along a longitudinal direction of the machine frame, so that guide grooves approach or leave the inverted cone-shaped ports; blades in a blade opening and closing mechanism and concave cutting edges on crank and rocker mechanisms can be driven by a fourth rotating and driving mechanism to form shearing ports; and the crank and rocker mechanisms make the reciprocating linear motion along with the leaf outlet groove. The stem and leaf separating machine has a good stem and leaf separating effect and is high in processing efficiency.

Description

technical field [0001] The invention relates to a device for separating tea stems and leaves of machine-picked fresh tea leaves, belonging to the field of agricultural machinery and automatic control. Background technique [0002] At this stage, with the gradual aging of my country's population structure, tea-picking labor is increasingly scarce. Every year, a large amount of green tea is wasted because it cannot be picked in time, and high-quality tea resources cannot be fully utilized. For this reason, the country vigorously advocates the mechanization and automation of tea production. At present, some automatic assembly lines can realize continuous production, but these production lines are mostly limited to the production of famous and high-quality tea, such as automatic continuous flat tea production line (Longjing tea), fried green tea clean Chemical production line (Huangshan Maofeng), etc. The current practice is: the tea leaves are not distinguished from the old an...

AI Technical Summary

Problems solved by technology

The current practice is: the tea leaves are not distinguished from the old and the young during the initial production, and only go through an electrostatic sorting or photoelectric sorting in the refining stage. This method consumes a lot of unnecessary energy during the primary production process; The factory crushes the tea leaves at the end of the initial stage of tea production, which is used to manufacture broken tea with lower quality grades, and the quality resources of tea leaves are not fully utilized.

[0003] On the other hand, the production of flake-shaped tea needs to go through the pulling process to remove the buds and tea stems. The typical representative is Lu'an Guapian, one of China's top ten famous teas, and the production of some large-leaf oolong teas. In fact, they all need a process of separating the tea stem from the leaves, but at present they are still mainly made by hand, with low productivity and heavy workload

[0004] Yet, up to now, still do not have a kind of effective device that can be used for tea fresh leaf stalk leaf separation
