When a clipper-type cutting blade is used as a pruning device for a traveling tea leaf pruning machine, a blower tube having a large number of blowing branch pipes is provided in front of the cutting blade, and above the cutting blade. A strong wind blows off the plucked tea leaves, and the wind blows the tea leaves into a tea bag connected behind a guide frame connected to the cutting blade.

[0004] The first problem is that the early buds contain a large amount of water and the tea leaves are heavy, so that they are difficult to float and slip along the guide frame. For this reason, in order to fly the tea leaves deep into the tea bag, a very strong wind is required.
A second problem is that tea astringent adheres to the bottom plate and both side plates constituting the guide frame, so that the friction of the tea leaves increases and the plucked tea leaves do not blow off. A third problem is that it is difficult to attach a tea bag to the rear end of the guide frame.

A fourth problem is that, as shown in Japanese Patent Application Laid-Open No. H10-262436, in a conventional traveling type tea picking machine, a blowing fan is directly connected to a blowing pipe and is integrated with a cutting blade. Remove it from the pipe and use it for another purpose,
It is very difficult to replace the air duct. or,
As shown in JP-A-8-266132, when a pruning device is provided behind the fuselage to perform a pruning operation, a separate fan must be provided to blow off tea leaves and branches on the pruning device. It must not be. The fifth problem is that when rainfall occurs, the surface of the tea leaves is wet, so that the tea bag containing the tea leaves becomes wet and heavy, making it difficult to pluck. The wet tea leaves are called dew leaves, and it takes a long time in the tea making process mainly for the drying operation, and the efficiency is reduced and the quality is reduced. Because of this,
Generally, you have to wait for the tea leaves to dry before picking them.
