DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timber transporting vehicle having a timber receiving portion provided at an upper portion of a vehicle body for loading and transporting timber.

[0002]

2. Description of the Related Art A conventional transportation vehicle is disclosed in, for example, Japanese Patent Application Laid-Open No. 6-32168. That is, the loading platform on the vehicle body is lifted by the cylinder, and the loading platform is inclined rightward or leftward about the right or left support shaft of the vehicle body, thereby facilitating unloading of the load such as gravel. I have.

[0003]

However, in the conventional transport vehicle, the structure for unloading the vehicle by tilting the carrier to the right or left side is complicated and the manufacturing cost is increased. An operation of removing a stop pin and opening a side door is required, and there is a problem that usability is poor.

The present invention has been made in view of such conventional problems, and has a simple structure for unloading the vehicle to the right or left side of the vehicle body, which is low in manufacturing cost, and which is easy to unload and easy to use. Aims to provide a good transport vehicle.

[0005]

According to one aspect of the present invention, there is provided a timber transport vehicle according to the present invention, wherein a timber receiving portion is provided at an upper portion of a vehicle body;
The vehicle body has a support portion for the housing portion; the housing portion is open at the top in a U-shape, and the housing portion is powered until the right or left side of its open end is lowest in the housing portion. The support portion is rotatably provided in the support portion, and the center of rotation of the support portion passes through the inside of the housing portion along the longitudinal center line of the vehicle body, and the portion of the housing portion on the bottom side from the rotation center is the rotation center. Being located at substantially the same distance from the center; and a crane being provided at an upper portion of the vehicle body.

The power for rotating the housing may be hydraulic power, electric power, or any other power. The storage section may have a frame shape, a box shape, or any other structure as long as it can store wood therein.

[0007]

In the timber transport vehicle according to the present invention, timber can be loaded and transported from above in the storage section. At the time of unloading, the storage unit can be rotated rightward or leftward by power and tilted to lower the open upper part and take out the wood from the upper part. Since the rotation center of the storage unit passes through the inside of the storage unit, the storage unit can be rotated even if the bottom of the storage unit is set at a lower position than when the rotation center is located below the storage unit. Since the portion on the bottom side of the rotation center of the housing is located at substantially the same distance from the rotation center, the housing can be rotated by setting the bottom of the housing at a lower position and increasing the capacity of the housing. . By setting the accommodating portion at a low position, the center of gravity is lowered, and stable traveling is possible.

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. As shown in FIG. 1 and FIG.
0 has a vehicle main body 11, a housing part 12, and a crane 13.

The vehicle body 11 is a tracked vehicle (carrier dump), and is easy to travel on a mountain road. The vehicle main body 11 has a cabin 21 at a front portion on the vehicle main body 11.
The cabin 21 is provided with a driver seat of the vehicle body 11. The accommodating portion 12 has a plurality of U-shaped frames 22, 22,... Arranged in parallel in the front-rear direction of the vehicle body 11, and a plurality of beams 23, 2 extending in the front-rear direction on the bottom and side portions thereof.
3, ... are fixed, and the front and rear portions are fan-shaped plates 24,25.
It is made up of blockades. The accommodating part 12 is a frame 2
, And beams 23, 23,... And plates 24, 25, the weight is light. The accommodation section 12 is provided on an upper part of the vehicle body 11. The upper part of the storage part 12 is open in a U-shape, and wood is loaded from the upper part.

As shown in FIG. 2, the vehicle body 11 has a pair of support portions 2 for supporting the accommodation portion 12 on its upper portion.
6, 27. One supporting part 26 is a cabin 2
1 frame, and the other support portion 27 is
1 at the rear. The support portion 27 is composed of a support pillar, and is provided vertically on the upper part of the vehicle body 11.

The accommodating portion 12 is rotatably mounted on the supporting portions 26 and 27. Gears 28 and 29 are fixed to the plates 24 and 25, respectively, and the gears 28 and 29 are rotatably mounted on support portions 26 and 27, respectively, by a rotation shaft. As shown in FIG. 1A and FIG.
Center of rotation A passes through the inside of the housing 12 along the vertical center line of the vehicle body 11. Since the housing portion 12 is composed of the U-shaped frames 22, 22,... A space is provided between the bottom of the housing portion 12 and the vehicle body 11 so as not to rub against each other.

A hydraulic motor 30 is mounted on the support 26. A gear 31 is fixed to a drive shaft of the hydraulic motor 30, and the gear 31 is engaged with the gear 28.
Thereby, the housing portion 12 is rotatable in both directions until the right or left side of the upper open end 12a is the lowest in the housing portion 12. The rotation operation section of the storage section 12 is provided in the cabin 21. The crane 13 is provided at the rear end of the upper part of the vehicle body 11.

Next, the operation will be described. In the wood carrier 10, in the state shown in FIG.
Wood can be loaded and transported from the upper part in the storage part 12.

At the time of unloading, the rotary operation unit is operated to drive the hydraulic motor 30, and as shown in FIG. 1 (B), the storage unit 12 is moved rightward or leftward according to the unloading position. Rotate and tilt to lower open top. As a result, the wood in the storage section 12 can be rolled out and unloaded. The wood in the storage part 12 is a U-shaped frame 2
Because it is placed on 2, 22, ..., it is easy to roll out.

In a conventional transport vehicle, it is necessary to open the side door of the loading platform when unloading, which is troublesome. However, in the timber transport vehicle 10, the unloading is not required and the loading operation is easy and the usability is good. In addition, the timber transport vehicle 10 is provided so that the storage unit 12 is rotatable in both directions with a rotation center A passing through the inside of the storage unit 12, and is rotated until the right or left side of the upper open end 12 a is the lowest in the storage unit 12 and unloads. Therefore, the structure for unloading is simple and the manufacturing cost can be reduced.

In the timber transport vehicle 10, since the rotation center A of the housing portion 12 passes through the inside of the housing portion 12, the bottom of the housing portion 12 is positioned lower than when the rotation center is located below the housing portion 12. Even if it is set to “
2 can be rotated. In addition, since the portion of the housing portion 12 on the bottom side from the rotation center A is located at substantially the same distance from the rotation center A, the bottom of the housing portion 12 is set at a lower position and the capacity of the housing portion 12 is increased, The part 12 can be rotated. By setting the accommodating portion 12 at a low position, the center of gravity can be lowered and stable running can be enabled.

[0018]

According to the timber carrier according to the present invention, the storage portion is provided so as to be rotatable in both directions by the rotation center passing through the inside thereof, and is rotated until a part of the upper open end is lowest in the storage portion. Since the vehicle is unloaded, the structure for unloading to the right or left side of the vehicle body can be simplified, the manufacturing cost can be reduced, and the unloading is easy and the usability is good. Further, in the wood carrier according to the present invention,
Since the bottom part of the storage part is located at approximately the same distance from the center of rotation, the bottom of the storage part should be set at a low position to lower the center of gravity, enable stable running, and increase the capacity of the storage part Can be.
