０は上下の牽引具８，８の連杆である。 The tilt drive device 5 is a crawler consisting of a crawler track 5' made of a rubber belt and its drive wheel 5'', but it may also be a tilt drive wheel.The driven device 6 is composed of an eccentric convex spherical idler wheel 6' and an eccentric shaft 6''. Although it is oriented toward the center of the tree trunk 7, it may be a general caster. Chain saw 1 is saw chain 1
2 and its guide plate 13, a pinion 15 provided on the output shaft of the prime mover 14 is meshed with the saw chain 12, and a drive wheel is connected via a drive chain 16, a reducer 17, and an interlocking device 18 that mesh with the pinion 15. 5'' and the drive device 5 can be rotated.The auxiliary machine frame 3 is formed of a curved tube as shown in FIG. , chain 2 on the other end
0 can be connected and engaged with a fork 8' provided at the tip of the traction tool 8. The base of the rope 8 is pivotally supported on the main engine frame 2 by a support shaft 21, and is moved from the imaginary line position (horizontal position) in Fig. 4 to the solid line position in the direction of arrow a.
It rotates more than 180 degrees, and the same traction device 8 is attached to the stopper 22.
The traction state self-holding device 9 by abutting the
can be done. Also, a hook 23 is provided at the tip of this towing tool 8, and is connected via a ring 25' to a pull-down rope 24 for both machine frames 2 and 3 suspended from the main engine frame 2 (see Fig. 4), so that it can be in the towed state. A release device 10 is formed, and a take-up reel 25 of the same rope 24 can be used as a device 11 for pulling down both machine frames 2 and 3, and by rotation of a handle 26 of the reel 25, the release device 10 can be formed. 10 can be linked to the unloading device 11. The traction device 8, the self-holding device 9 and the releasing device 10 are formed by solenoids,
The unloading device 11 can be a wireless signal device for controlling the solenoid. In addition, what is indicated by 27 in the figure is a direct descending roller 2 that presses against the tree trunk 7 and separates the drive device 5 from the tree trunk 7 by pulling the rope 24 downward.
8 is its support lever, 29 is the support shaft of the same lever 28, 3
0 is the connection between the upper and lower traction tools 8,8.
従つて樹幹７を旋回上昇させるに当つては牽引

２３から外れてロープ２４が槓杆２８の先端を下
方に牽引するから直下降ローラ２７が第２図左方
に動作して駆動装置５を樹幹７から分離し、両機
枠２，３を地上に直下降させることができる。 Therefore, when the tree trunk 7 is turned upward, when the towing tool 8 is rotated in the direction of arrow a, the spring 4 is towed and both machine frames 2 and 3 can be strongly pressed against the tree trunk 7, and the tree trunk 7 is lowered directly. If so, use the radio to operate the solenoid 30 shown in Figure 2 to move the reel 25 to the claw 3.
When the handle 26 is rotated, the rope 24 rotates the traction device 8 via the ring 25' to the imaginary line position in the direction opposite to the arrow a in FIG. 4, thereby relaxing the spring 4. At the same time, the ring 25' comes off the hook 23 and the rope 24 pulls the tip of the ram 28 downward, so the direct lowering roller 27 moves to the left in FIG. , 3 can be lowered directly to the ground.

降し得て樹皮を損傷するおそれもない。 Since this project is configured as described above, both machine frames 2 and 3
When the tree turns upward, the spring 4 is strengthened and the tree trunk 7 can be safely raised without slipping, and the pruning work is performed smoothly.When the tree descends straight, the spring 4 is loosened and the tree can descend smoothly, damaging the bark. There's no risk of it happening.
