Slightly in front of the pillar on which the tea leaves are caught, a hair clipper blade for picking tea leaves reciprocates left and right. Therefore, if the movement of the hair clipper blade is used to perform the dispelling operation, not only the small motor but also the flexible wire described in the inventions of claims 2 to 8 need not be used, and the most reasonable plucking is performed. You can get rid of the tea leaves.

According to the second aspect of the present invention, a clipper-type cutting blade that covers the entire width of the tea ridge is attached to a gate-shaped body that straddles the tea ridge, and the tea leaves are picked while moving along the tea ridge. In the apparatus, means for driving a tea leaf dispenser provided in front of a center support of the cutting blade by a flexible wire including a core wire and an outer tube is used. The cutting blade of the full cutting is adjustable up and down in order to adjust to the height of the tea plant, and the support at the center of the cutting blade and the wiping device provided in front thereof also move up and down together with the cutting blade. Therefore, if it is attempted to receive the power of the dispensing device from another place of the body without using a small motor, it cannot be fixed by a drive shaft or the like.
However, if a flexible wire is connected to a power source in the body, power can be transmitted even when the position of the sweeping device is moved up and down.

According to the third aspect of the present invention, there is used means for connecting the other end of the flexible wire connected to the wiping device to the drive unit of the traveling device. According to the fourth aspect of the present invention, there is provided means for connecting the other end of the flexible wire connected to the blower with the drive unit of the blower fan.

I just need. When power is obtained from the blower fan of claim 4 or the power source of the cutting blade of claim 5, since the rotation speed is high, either the speed is reduced before connection to the flexible wire or the speed is reduced after the flexible wire. Even so, a speed reduction mechanism is required.

In the invention of claim 6, the flexible wire uses a means for transmitting reciprocating motion. In the invention according to claim 7, the flexible wire uses means for transmitting a rotational motion. In order for the flexible wire to transmit power through the core wire inside the outer tube, a method of reciprocating the inner core wire and a method of rotating the core wire to make the rotary motion to the outer cylinder are used. There is. If the repelling device is reciprocating, provide a crank on the rotating shaft of the power on the input side of the flexible wire, change the rotating motion to reciprocating motion, and connect it to the flexible wire. It can be connected to a connection device. Without providing a crank on the input side, connect a flexible wire to the rotating shaft as it is,
In the case of transmitting by rotary motion, it is necessary to provide a crank on the output side, change the rotary motion into reciprocating motion, and connect to a repelling device. In the case where the repelling device is a rotating body, the rotation on the input side may be directly transmitted by a flexible wire, and the rotating shaft on the output side may be directly connected to the rotating body.

According to the invention of claim 8, the repelling device is a repelling bar protruding downward from a front upper portion of a center post of the cutting blade, and the repelling bar is centered on a fulcrum provided on the upper portion. A structure is used in which tea leaves are shaken left and right to remove the tea leaves caught on the support, and a flexible wire is connected to the removal device. In this way, it is possible to provide the simplest and most effective dispelling device that operates by using the power source of the body instead of the small motor.
