Then, there is a problem that this system cannot be introduced. In addition, when a riding tea leaf plucking machine is used, the ground may be compacted depending on the weight of the plucking machine, and this may cause poor excavation during tillage work, making management work difficult. There is.
[0006]
On the other hand, the picked tea leaves are taken into a storage means such as a tea bag, but when the storage means is filled with tea leaves, it is necessary to replace it with a new storage means. For this reason, conventionally, the operator performs the plucking operation while visually observing that the storage means is full, interrupts the plucking operation when it is full, and once gets out of the plucking machine and replaces the container. ing. However, it is not only poor in workability but also painful for the operator to repeat the boarding / alighting operation with respect to the picking machine every time the accommodating means is replaced.
[0007]
The present invention has been made to solve such a problem, and while taking advantage of the advantages of the track rail type and the riding type tea leaf picking machine, the operability of the operator required for replacing the tea leaf container is also achieved.
