Abstract

(57) Abstract: The present invention provides a pruning machine that mechanically prunes a tree. A tree pruning machine in which a rotating disk machine (2) is attached to the tip of a vertically tiltable arm (3) so that it can be held and changed horizontally and vertically and the vertically tiltable arm (3) is installed on a self-propelled carriage (8).

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a tree pruning machine.

[0002]

[Prior art]

 When pruning small trees, the operator manually prunes them using pruning scissors, a saw, etc.For large tree pruning, a stepladder, ladder, etc. are placed around the trees to allow the worker to climb to a high place. The pruning work is performed manually by the operator using pruning scissors, a saw and the like.

[0003]

[Problems to be solved by the device]

 When pruning a tree as described above, pruning is performed while moving several steps such as stepladders and ladders to finish pruning one tree, then moving to another tree, and pruning one tree in the same manner. Pruning is performed while moving to several places, and the work efficiency is extremely low, and the scaffolding is unstable in high places, which poses a problem such as dangerous work.

[0004]

[Means for Solving the Problems]

 The feature of the present invention is that the rotary disk machine is held horizontally and vertically, and is attached to the tip of the elevation / revolution arm freely changeable, and the elevation / revolution arm is installed on the self-propelled carriage. It is a tree pruning machine.

[0005]

[Embodiment of device]

 An example of the present invention will be described with reference to the drawings. As shown in FIG. 1, a rotary disk machine 2 in which a plurality of circular saws, circular blades, etc. are arranged as a rotary blade 1 is attached to the tip of a vertically swingable arm 3 via an attachment 4 and a slide flange 5 as shown in FIG. The stopper 6 is fixed to the pin 7 to hold the rotary disk machine 2 in the vertical direction. When the rotary disk machine 2 is held horizontally, the stopper 6 is removed, the stopper 6 is removed from the rotary disk machine 2 holding frame 10, and then the rotary disk machine 2 holding frame 10 is removed as shown in FIG. To fix the rotating disk machine 2 in the horizontal direction. Thus, as shown in FIG. 4, the rotary disk machine 2 is attached to the tip of the vertically rotatable arm 3 in the horizontal and vertical directions, and the vertically rotatable arm 3 is installed on the self-propelled carriage 8.

However, when pruning the upper part of the tree, as shown in FIG. 5, the rotary disk machine 2 attached to the tip of the swingable arm 3 is held horizontally and rotated around the bolts and nuts 11. After fixing by bolting, operate the elevation / rotation arm 3 to position it on the top of the tree 9, and then operate the elevation / rotation arm 3 with a hydraulic motor (not shown) installed in the rotating disk machine 2. Driven in cooperation with the hydraulic system, the rotary blades 1 connected by belts are rotated to prun the upper part of the tree 9, while moving by itself to prun the tree row. Further, when pruning the side part of the tree 9, as described above, the rotary disk machine 2 is held and changed in the vertical direction, and is positioned on the side part of the tree 9 as shown in FIG. It moves and prunes a row of trees.

[0007]

[Effect of device]

 According to the present invention, the pruning of trees can be performed mechanically (automatically), so that many trees can be pruned in a short time and the pruning ability can be significantly improved. Further, it is possible to obtain an excellent effect such that the worker does not have to work at a high place, the dangerous work can be released, and the labor can be saved.
