And an arm 32 for pressing the rotating bodies 31, 31 in the direction of the felled timber 100. These rotating bodies 31, 31 are attached with their rotating shafts inclined, and the logging materials 100 are placed diagonally from above onto the loading rollers 21, 22.
To be pressed.

FIGS. 6 and 7 are views showing the delimer device of the pruning device according to this embodiment. FIG. 6 is a front view, and FIG. 7 is a side view. The derimer device 40 includes a rotating ring 41,
It comprises two sets of chainsaw units 42, 42 provided inside the rotating ring 41. The chainsaw unit 42 is provided inside the rotary ring 41 so as to be rotatable around a shaft 42 a, a hydraulic cylinder 44 for driving the holder 43, and a swing motor provided at the tip of the holder 43 so as to swing. And a head 45 provided with
5 includes a chainsaw 46 provided so as to be substantially parallel to the rotation axis of the rotating ring 41.

The chainsaw 46 can be moved by the expansion and contraction of the hydraulic cylinder 44 so as to fit the logging material 100 having a diameter from the maximum diameter φ1 to the minimum diameter φ2. In this embodiment, φ1 = 600 mm and φ2 = 100 mm. In the chainsaw unit 42, casters 47 are provided on the holder 43, and can be moved at a predetermined distance on the outer periphery of the felled timber 100. The casters 47 may be omitted, and the head 45 may be provided with a similar guide member.

In FIG. 6, a rotary ring 41 is provided with a gear 48, and a small gear (not shown) of the output shaft of the motor is connected to the internal teeth while the external teeth are guided by a support frame (not shown). As a result, the driving force is transmitted, and the vehicle can rotate by itself.

FIGS. 8 and 9 are views showing the centering device of the wiping device according to the present embodiment. FIG. 8 is a front view and FIG. 9 is a side view. The centering device 50 is a device for aligning the feed device 20 and the delimer device 40. In this embodiment, the center of the delimer device 40 is aligned with the center of the felled timber 100 on the feed device 20. It was made. The centering device 50 includes a frame 51 that supports the delimer device 40, a guide rod 52 that guides the frame 51 in the vertical direction, and a lifting cylinder 53 that uses hydraulic pressure or the like to drive the frame 51 in the vertical direction. , A potentiometer 54 for detecting the elevation position of the delimer device 40
And so on.

As shown in FIG. 1, the vehicle 1 has an outrigger jack 2 for a crane and a processor 10
An outrigger jack 3 for the table is provided below the table 11. In addition, a generator 4, a hydraulic device 5, a high-frequency oscillator 6, and the like are mounted. Further, a cargo handling device 70 is arranged beside the processor 10.
The cargo handling device 70 includes a crane 71, a driver's seat 72,
The control box 73 includes a control panel 74 and the like.

Next, returning to FIGS. 1 to 5, the operation of this embodiment will be described together with the detailed structure. The vehicle 1 travels from the logging site or the logging site to an accumulation base of the logging material 100 that has been lowered using a tower yarder or the like. First, the outrigger jack 2 for the crane is stretched and the table 11 is slid, and then the outrigger jack 3 for the table is stretched to stabilize the vehicle 1.

Next, the cargo handling device 70 causes the felled timber 10
0 while inserting the base side of the
It is placed on the 0 placement rollers 21 and 22. Then, the upper side of the felled timber 100 is pressed by the pressing roller 23.
In this state, the chainsaw 46 of the delimer device 40 is rotated around the logging material 100 while feeding the logging material 100 forward of the vehicle 1 by the feed device 30,
I will remove the branch 101.

Since the felled timber 100 becomes thinner toward the tip, the chain saw 46 always keeps a constant distance from the center of the felled timber 100 by lowering the delimer device 40 by the centering device 50. To rotate. Even if the felled timber 100 is long, the processor 10 is shifted to the outside of the side surface of the vehicle 1, so that the timber can be pruned to the tip without interfering with the vehicle 1. When the pruning of the felled timber 100 is completed, the tip of the felled timber 100 is cut by the backing saw 60, and the felled timber 100 is adjusted to a predetermined length.

The processor 10 can be tilted at a predetermined angle (for example, about 10 degrees) with respect to the table 11 by the tilt cylinder 12 and the rotating shaft 13 as shown in FIG. In this way, even when the felled timber 100 is relatively thin and the tip is bent, the pruning can be reliably performed.

Various modifications and changes are possible without being limited to the above-described embodiment, and these are included in the equivalent scope of the present invention. For example, the centering device
Although the example in which the delimer device is moved up and down has been described, the feed device 20 may be moved up and down. The processor 10
Has been described as an integral type with the vehicle 1, but may be a method of loading and unloading from the bed of the vehicle 1. For pruning,
Although the chainsaw 46 is used, a method using a circular saw may be used.

[0024]

As described above in detail, according to the first aspect, since the feed is carried out by the moving means while being supported by the support means and the wiping is carried out by the rotating wiping means, heavy and long pruned timber is cut off. Can be performed safely and easily. According to the second aspect, since the centering means is provided, the branches can be reliably removed according to the change in the thickness of the felled timber. According to the third aspect, since the cutting means is provided, the felled timber from which the branches have been removed can be cut to a predetermined length. According to the fourth aspect, the debranching means uses a chainsaw or a circular saw for the rotating cutting teeth, so that damage to the felled timber can be reduced.

According to the fifth aspect, since the pruning device is mounted on the vehicle body, the pruning device can be transported to the logging site, and the pruning can be performed at the logging site. According to the sixth aspect, when the pruning device is mounted on a vehicle, the pruning device can be shifted to the outside of the side surface of the vehicle, so that even a long cut timber can be pruned without interfering with the vehicle. According to the seventh aspect, since the pruning device is inclined forward and upward, the pruning can be reliably performed even if the felled timber is bent relatively thinly. According to the eighth aspect, since the cargo handling means for supplying the felled timber to the pruning device is provided in parallel, a series of pruning operations can be mechanized.
