 The pruning work, trimming work and tea cutting work are generally carried out on each side of the ridge while two workers are standing on both sides of the ridge in a tea field and walking along the ridge while holding the handles such as a pruning machine. . However, since a pruning machine equipped with an engine is heavy, two workers stood on both sides of the ridge while holding the handles of the pruning machine and walking along the ridge while pruning each side of the ridge. Performing work, trimming work or tea cutting work is a heavy labor. Therefore, continuous work for a long time is difficult, and the workable area per day is also limited. In addition, since the worker holds the handle of a heavy pruning machine by hand, the vibration of the engine and the mowing is directly transmitted to the hand, and as a result, the worker often complains of numbness in the hand. It is possible to use a self-propelled type or a riding type as the pruning machine, but in this case, the machine becomes large and it becomes difficult to load and unload it from a transport vehicle or move in a narrow tea garden, and the machine itself It will be extremely expensive.

Therefore, the applicant of the present invention, as shown in FIG. 10, rotatably attaches wheels 3 and 5 to the front end and the rear end of the wheel support frame 1, respectively, and to substantially center the wheel support frame 1.

[0011]

[Action]

 [Supporting trolley for the branching machine and the like according to claim 1] The supporting trolley for the branching machine and the like according to claim 1 is used by two workers. That is, one worker grips the handle of the supporting carriage on one side of the ridge while one end of the branching machine or the like is rotatably locked to the supporting rod of the supporting carriage, and the other one worker holds the ridge. The other side has a handle at the other end of the branching machine. In this way, both workers proceed in the same direction along the ridge in a state where the pruning machine or the like is applied to one side of the ridge, and perform cutting work, trimming work or tea cutting work on each side of the ridge. (See FIG. 1).

Wheels are rotatably attached to the front end and the rear end of the wheel support frame, respectively, and a central shaft is tilted within a certain range in the front-rear direction with respect to the wheel support frame at a substantially central portion of the wheel support frame. Since the wheel support frame is pivotally mounted as described above, the wheel support frame is rotatable in the up-down direction about the pivot axis of the wheel support frame and the central shaft. Therefore, when overcoming the unevenness of the ground and the unevenness of the cut-off tea tree branches, the vertical movement of the front and rear wheels suppresses the vertical movement of the central shaft to a minimum, and the support truck can move smoothly. Also, the angle of the cutting edge of a branching machine can be changed by tilting the central axis in the front-back direction. When the central shaft is tilted in the front-rear direction beyond the range in which it can be tilted with respect to the wheel support frame, one of the front and rear wheels floats up, so when moving from one ridge to another, only one of the wheels touches the ground. The support cart can be smoothly turned in this state. Since the wheels are vertical wheels attached to the front end and the rear end of the wheel support frame, the support truck has excellent straightness and can be stretched evenly.

Since the handle is attached to the central shaft in such a manner that its height can be adjusted, the height of the handle can be adjusted according to the height of the back of the worker. Since the height of the pruning machine is adjustable on the central shaft, the height of the pruning machine can be adjusted according to the tree height and the required cutting depth.

Therefore, in the present invention, the front wheel is a wheel having a diameter smaller than that of the rear wheel, and the elevating cylinder is slidably fitted to the central shaft from the vicinity of the upper end of the central shaft to the vicinity of the lower end thereof, Is equipped with a first fixing screw for fixing the elevating cylinder to the central shaft, and further, a supporting rod is attached to the elevating cylinder so that one end of a branching machine or the like is locked to the front end of the supporting rod. Therefore, the one end of the branching machine can be lowered to the same height as the vicinity of the lower end of the central shaft, if necessary. Therefore, the pruning machine or the like can be sufficiently lowered to the bottom of the tea plant. Moreover, since the pruning machine and the like are rotatably locked to the support rod, the pruning machine and the like are extremely easy to use.

[Supporting Carriage for a Branching Machine or the Like According to Claim 2] In a supporting car for a branching machine or the like according to Claim 2, a supporting cylinder in the front-rear direction is fixed to the lifting cylinder, and the supporting cylinder supports the supporting cylinder.
