This type of device uses a rail laid between the left and right ridges sandwiching the tea tree ridge as a pair of tracks to form a gate-shaped frame that straddles the tea tree ridge between left and right track carriages that move along the rails. A plucking device equipped with a mowing part and a bag receiving part over the entire surface of the tea tree ridge is vertically movably mounted on the portal frame. When plucking tea leaves, the track carriage is advanced with the cutting blade lowered to the plucking depth of the tea tree ridges, and the tea leaf plucking work is performed by this forward movement and the plucked tea leaves are stored in a bag. When the plucking work of a predetermined path is completed, the cutting blade is raised to a predetermined height and returned to the plucking work start end at high speed, and the stored tea leaf bag is exchanged for the next plucking work. .

When the work on one tea tree ridge is completed, the orbital tea leaf plucking machine has to be moved to the rail laid between the other ridges. A moving device between the tea ridges as described in Japanese Patent Publication No. 4-77706 has been proposed. This moving device for tea ridges is located at the end of the rail laid between the ridges, lays a rail for moving the tea ridges in the direction connecting the rails, and is a track type on a trolley that moves on this rail. The tea-plucking machine is loaded and moved. Then, on the trolley, a rectangular trolley frame is provided with two auxiliary rails on which the orbital type tea leaf plucking machine is to be mounted, substantially parallel to each other at predetermined intervals, and the auxiliary rails are slidably attached to the trolley frame. There is.

This conventional work for moving between the tea ridges is performed according to the following procedure. First, before the track type tea leaf plucking machine arrives at the end of the rail laid between the ridges, the tea ridge moving carriage is moved along the tea ridge moving rail, and one auxiliary rail provided for the tea ridge moving carriage is provided. , Stop at a position close to one of the rails on which the track type tea leaf plucking machine is mounted. Then, the positions of the auxiliary rails on the bogie frame are adjusted so that the auxiliary rails of the tea ridge moving carriage and the ridge rails are aligned with each other, and the both rails are connected by the connecting tool. After that, the worker lifts one side of the orbital type tea leaf plucking machine that has arrived at the end of the rail, and puts one leg wheel of the orbital type tea leaf plucking machine on the auxiliary rail on the side of the connected tea ridge moving carriage. Let Then, the connected auxiliary rail is returned in parallel to the other auxiliary rail at a predetermined interval, and the leg wheel on the side lifted by the operator is placed on the other auxiliary rail. After that, the tea ridge moving carriage on which the track type tea leaf plucking machine is placed is moved to the front of the tea tree ridge to be moved, and the track type tea leaf plucking machine is transferred onto the rail laid in the ridge by the procedure opposite to the above.

However, it is very difficult and dangerous to move and stop the ridge-moving carriage on which the track type tea leaf plucking machine is mounted along the slope to a desired position. This is because the weight of the orbital type tea leaf plucking machine exceeds 100 Kg, it is impossible to move from the low side of the slope to the high side, and the work is from the high side of the slope to the low side. In this case, in the conventional furrow moving carriage, the operation of stopping the moving carriage at the desired position is performed by operating the two brake tires with the hand levers, but at the desired accuracy with the desired position. It is very difficult to stop the moving carriage, and if the carriage slips to the lower side than the position where it was attempted to stop, support the moving carriage on the lower side of the slope to return it to the higher side. This is because the work requires an auxiliary worker and is extremely dangerous.

As described above, the conventional furrow moving carriage requires two or more workers including an auxiliary worker when it is used on a sloping ground, and it is a dangerous work. Therefore, expensive equipment investment is required. This resulted in the loss of the advantages of the orbital type tea leaf plucking machine.
