Description

[0001]
[Industrial applications]
The present invention relates to a rotary leaf collecting apparatus for collecting tea leaves. More specifically, the present invention relates to a rotating leaf collecting apparatus that is installed in a riding type tea pruning machine and collects tea leaves while rotating tea leaves.
[0002]
[Prior art]
The riding type tea picking machine is a machine for picking tea by operation of an operator, and the tea picking machine is provided with a rotary leaf collecting device for collecting the picked tea leaves.
[0003]
Tea leaves plucked by the cutting blade portion are fed to the separation portion through the feed pipe, and are separated into air and tea leaves by the separation portion, and are discharged from the feed pipe discharge port. The tea leaves discharged from the feed pipe discharge port are collected in a rotary collecting device.
[0004]
[Problems to be solved by the invention]
However, in the conventional rotary leaf collecting apparatus, the tea leaves are stored as they are in the plurality of leaf collecting bags arranged on the rotary leaf collecting frame body without any change in the mass of the fresh leaves. Therefore, the tea leaves are in a state of being “soft” with the tea leaves contained therein, and are in a state where there is still enough room. For this reason, the actual situation is that the auxiliary worker pushes in the tea leaves which are bulky and stored by hand.
[0005]
