[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is a whole-plucking device that can be vertically adjusted with respect to the height of a tea tree ridge by moving the tea tree ridge along rails laid between the left and right ridges of the tea tree ridge. The present invention relates to a traveling carriage for a tea leaf full surface plucking machine provided with a tea leaf storage bag support.

[0002]

2. Description of the Related Art Conventionally, rails are laid between left and right ridges of tea tree ridges planted in rows, and a traveling carriage that travels along the rails so as to straddle the tea tree ridges is used to adjust the height of the tea tree ridges. There is known a tea leaf plucking machine provided with a plucking device that can be adjusted vertically. And the plucking device is one-sided cutting,
It is common practice to vertically adjust the plucking device at two locations, a side end portion and a widthwise central portion of the traveling carriage. Further, the tea leaf accommodating bag attached to the rear part of the plucking device moves from the upper surface of the tea tree ridge from which the tea leaves have been plucked down to the ridges so that the ridges can be dragged.

[0003]

In the above-mentioned conventional rail-moving type tea leaf plucking machine, the plucking device is vertically adjusted at two positions, that is, the side end of the traveling carriage and the central portion in the width direction. The work was troublesome and I was not able to do it quickly. Also, since the tea leaf storage bag moves so that the ridges can be dragged from the upper surface of the tea tree ridge from which the tea leaves have been plucked,
The pulling resistance was great, and when the tea leaves in the tea leaf storage bag became full (about 20 kg), the traveling carriage did not move smoothly, and stable tea leaf picking work could not be performed. Further, the tea leaf storage bag is easily damaged because it comes into contact with the branches of the freshly cut tea tree, and further, the contact of the tea leaf storage bag with the branches of the freshly cut tea tree causes the transmission of diseases such as ring spot disease, There was a fear of spreading it. The present invention has been made for the purpose of solving the above various problems.

[0004]

[Means for Solving the Problems] In order to achieve the above object, the present invention lays rails between the left and right ridges of tea tree ridges planted in rows and straddles the tea tree ridges along the rails. In a tea leaf plucking machine, in which a traveling cart that moves in a vertical direction is provided with a plucking device that can be adjusted up and down with respect to the height of the tea tree ridge,
The rods installed inside the props on the left and right sides of the front part of the traveling trolley respectively, and the tea leaf storage device attached to the rear surface of the whole surface plucking device and the whole surface plucking device via the elevating body that is elevated by rotating the screw rods Supporting the accommodation bag support that supports the bag, the left and right screw rods are connected by a rotating shaft to enable rotation of both screw rods by one rotating handle, and a recess is formed in the rear portion of the accommodation bag support. The storage bag support is movable back and forth.

[0005]

With the above construction, the traveling cart of the tea leaf plucking machine of the present invention can be moved up and down by rotating both screw rods by one rotating handle of the plucking device and the accommodating bag support. Vertical adjustment of the bag support is accurate, simple and easy. In addition, since the tea leaf storage bag is supported by the storage bag support, the tea leaf storage bag does not come into contact with the upper surface and the furrows of the tea tree cut off,
There is no increase in traction resistance or damage to the tea leaf storage bag, and there is no risk of transmitting or spreading diseases such as ring spot disease. Further, since the storage bag support is provided with a recess and can be moved back and forth, the tea bag storage bag can be easily replaced by sliding the storage bag support back and forth in the recess.
