[0003]

[Problems to be solved by the device]

 However, since a pruning machine equipped with an engine is heavy, two workers stood on both sides of the ridge and walked along the ridge while holding the handles of the pruning machine, etc. Performing branch work or trimming work is hard work. Therefore, continuous operation for a long time is difficult and the workable area per day is limited. In addition, since the worker holds the handle of a heavy pruning machine by hand, the vibration of the engine and the cutting 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 from a carrier vehicle or move in a small tea garden, so the machine itself. Is extremely expensive. The present invention has been made in order to solve the above problems and to provide a support cart such as a pruning machine which is lightweight and has a simple structure.

[0009]

[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, with one handle (handle on the engine side) of a pruning machine or the like being held by the holding means of the support carriage, one worker grasps the handle of the support carriage on one side of the ridge and the other The worker holds the other handle of the pruning machine on the other side of the ridge. 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 the pruning work or the trimming work on each side of the ridge ( See FIG. 2). Since the engine side of the branching machine etc. is held by the holding means, most of the weight of the branching machine etc. will be supported by the supporting carriage, and the vibration of the engine and the mowing will be directly in hand. It will not be transmitted. Wheels are rotatably attached to the front end and the rear end of the wheel support frame, respectively, and a central shaft is provided at a substantially central portion of the wheel support frame such that the central shaft can be tilted with respect to the wheel support frame within a certain range in the front-rear direction. Since the wheel support frame is pivotally attached, the wheel support frame can be rotated in the up-down direction about the pivot axis of the wheel support frame and the central shaft. Therefore, when riding over the unevenness of the ground and the unevenness of 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. it can. Moreover, the angle of the cutting edge of a branching machine or the like 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 tiltable range 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 should be lifted. It is possible to smoothly change the direction of the supporting carriage while being grounded. Since the wheels are vertical wheels attached to the front and rear ends of the wheel support frame, the support truck has excellent straightness and can be stretched evenly. Since the handle is mounted on the central shaft so that its height can be adjusted, the height of the handle can be adjusted according to the height of the worker's back. The holding means for detachably holding the pruning machine or the like is height-adjustable, and the height of the pruning machine or the like can be adjusted according to the tree height and the required cutting depth. Since the holding means such as the pruning machine is rotatable in the horizontal direction, the horizontal direction of the pruning machine or the like can be adjusted appropriately. The pruning machine and the like can be attached to and detached from the holding means as needed.

[Supporting Cart for Branching Machine, etc. of Claim 2] In the supporting cart for branching machine, etc., when the worker grips the lever attached to the handle toward the handle, each arm is It moves in the direction of approaching the main shaft, moves the sliding cylinder upward, and moves the holding means such as a branching machine attached to the sliding cylinder upward. On the other hand, since the sliding cylinder tends to always move downward due to the weight of the branching machine or the like, when the worker releases the lever attached to the handle, the branching machine or the like held by the holding means descends slightly. Therefore, the worker can adjust the height of the branching machine or the like by the lever attached to the handle. Further, since the holding means such as a branching machine is attached to the sliding cylinder via the height adjusting means, the holding means can further adjust the height by the height adjusting means.

[Supporting cart for a branching machine or the like according to claim 3] In the supporting cart for a branching machine or the like according to claim 3, when an operator grips the lever attached to the handle toward the handle, it is substantially L-shaped. The member rotates in the direction of moving the sliding cylinder downward, and moves the holding means such as a branching machine attached to the sliding cylinder downward. Since the spring compressed between the sliding cylinder and the main shaft has a function of returning the sliding cylinder to the original position, when the worker releases the lever attached to the handle, the branch held by the holding means is released. The machine, etc. rises to its original position. Therefore, the worker can adjust the height of the pruning machine etc. by the lever attached to the handle. Further, since the holding means such as a branching machine is attached to the sliding cylinder through the height adjusting means, the holding means can further adjust the height by the height adjusting means. Furthermore, the spring that is compressed between the main shaft and the sliding cylinder to which the holding means such as a branching machine is attached absorbs the vibration of the engine and the cutting machine such as the branching machine. Vibrations of the engine and trimming are not transmitted to the operator holding the handle.

[Supporting cart for a branching machine or the like according to claim 4] In the supporting cart for a branching machine or the like according to claim 4, the holding means of the branching machine or the like detachably holds the grip of the branching machine or the like. A holding tool is provided, and the holding machine can be attached to the holding means by holding a handle such as a branching machine with the holding tool. It is also possible to remove the pruning machine or the like from the holding means.

[Supporting trolley for a branching machine or the like according to claim 5] In the supporting trolley for a branching machine or the like according to claim 5, the wheel support frame, the wheels, the base of the handle and the lower part of the central shaft are covered with a cover. Therefore, the branches of the tea plant are not caught in these parts, and the support truck runs smoothly in the tea garden.
