Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a winch wire guiding device for winding and guiding a winch wire of a tractor.

[0002]

When a load is pulled or a tractor body itself is pulled by providing a winch on a riding tractor and winding up a wire, the body of the tractor may be raised or lowered depending on the installation location of the winch. , Local stress concentration is likely to occur.

[0003]

According to the present invention, a winch 4 is provided on a rear abdomen of a vehicle body 3 having a front wheel 1 and a rear wheel 2.
And a rear roller 6 for guiding the wire 5 of the winch 4. A front roller 7 for guiding the front portion of the wire 5 is provided on the front abdomen. The front roller 7 is drawn forward through the rear roller 6 and the front roller 7. A pair of upper and lower guide rollers 8 and 9 for guiding the front portion of the wire 5
The tractor winch wire guide device is provided on the front axle bracket 10 at the front.

[0004]

The wire 5 wound by the drive of the winch 4 is guided by upper and lower guide rollers 8 and 9 at the front of the vehicle body 3, and is guided by a front roller 7 and a rear roller 6 for winding. Such a winch 4 or a guide roller 8,
9, and a vehicle body 3 such as a front roller 7 and a rear roller 6
The configuration is simple because it is arranged on the abdomen of the subject. Further, since the wire 5 is stretched substantially horizontally and over substantially the entire length of the vehicle body 3 in the front-rear direction, the pulling of the wire 5 can be received by the entire vehicle body 3. Concentration of local forces on the guide rollers 8, 9 and the like is reduced, and a stable winch operation can be performed.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tractor body 3 has a front wheel 1 and a rear wheel 2 which can be steered by operating a steering handle 11, and an engine 13 mounted under a hood 12 at the front.
It is possible to travel by transmission. A cockpit 15 is provided at the rear, and a step floor 1 extends from the front to the left and right sides.
6 and side floors 17 are provided. Reference numeral 18 denotes a boarding / alighting step. Reference numeral 14 denotes a lift arm having a rear hitch for connecting a working machine.

A front axle bracket 10 is provided at a lower front portion of the vehicle body 3, an engine 13 is mounted on an upper side, and a front axle housing 19 is supported on a lower side. Case 21 for connecting the front wheel 1 to the lower end portion
Having. A rear axle housing 22 is supported on the lower rear portion of the vehicle body 3, and a final case 23 for a raised floor is provided on both left and right ends, and a steering case 24 on which the rear wheel 2 is mounted is provided at the lower end.

The winch 4 is arranged on one side of the rear part of the vehicle body 3 and on the front side of the rear axle housing 22. Mounting brackets 2 on both left and right sides of rear axle housing 22
Connecting arms 28 and 29 are provided from 5, 26 to a winch mounting base 27. The winch mounting base 27 has an arm 30 and is directly mounted on the vehicle body 3. It is provided at a position where it does not hinder the steering of the rear wheel 2.

The winch 4 has a motor M on one side and can drive a winding drum 31 around which the wire 5 is wound. The motor M may be configured to be electrically driven by power generation by driving the engine 13. The winding drum 31 is fixed to the upper surface of the winch mounting base 27 so that the axial direction of the winding drum 31 is orthogonal to the connecting arm 29 on the opposite side. The rear roller 6 is provided at a lower portion near the mounting bracket 26 of the connecting arm 29. The front roller 7 is arranged at the front lower portion of the front axle housing 19 and on the same side as the winch 4, and is attached to the front axle housing 19 by a mounting bracket 32.

The front roller 7 is provided at a diagonal position with respect to the rear roller 6, and is disposed at substantially the same height as the winch 4 and the like. A pair of upper and lower guide rollers 8 and 9 is provided with a front hitch 33 on the front side of the front axle bracket 10.
Attached to The guide rollers 8, 9 are set so as to be suitable for the guide width of the wire 5, and are axially mounted in the left-right horizontal direction. Further, the guide rollers 8 and 9 may be directly mounted on the front axle bracket 10.

The guide surface of the wire 5 by the guide rollers 8 and 9 is arranged at substantially the same height as the rollers 6 and 7 and the like. The front axle housing 19
A hook 35 fixed by a mounting bracket 34 is provided at a position opposite to the front roller 7 so that the tip of the wire 5 drawn out between the guide rollers 8 and 9 can be engaged.

Reference numeral 36 denotes a roller for winding the wire 5 drawn forward from between the guide rollers 8 and 9, and reference numeral 37 denotes a hanger hook provided with the roller 36 rotatably. When the tractor body 3 is to be escaping during traveling work in a wetland, the hanger hook 37 of the wire 5 drawn forward from between the guide rollers 8 and 9 as described above is pulled to the anchor 38 driven into the front ridge or the like. The wire 5 is wound around the winding drum 31 by driving the winch 4.

The vehicle body 3 is drawn toward the anchor 38 by the wire 5 guided by the rear roller 6 and the front roller 7 to escape from the wetland. When the anchor 38 is set lower than the guide rollers 8 and 9, the front wheel 1 generates a component to be pushed down, and the rear wheel 2 does not generate a component to be pushed. 4 is different from the above example in that a hanger hook 40 having a roller 39 is located on the rear side of the vehicle body 3, and the wire 5 of the winch 4 is used by being wrapped around the roller 39 from the rear roller 6. Can be. Reference numeral 41 denotes a hook for locking the tip of the wire 5 and is attached to the rear axle housing 22 at the rear of the winch 4.

In such an embodiment, the pair of upper and lower guide rollers 8 and 9 may be provided at the rear of the vehicle body 3.
