Description

[Detailed description of the invention] The present invention has wheels on a walking-type reaper main body, which has one drive running wheel in the front and back direction when viewed from the side, and has a steering handle extending rearward and upward. The riding device is detachably connected, and by attaching and detaching the riding device, 1
This invention relates to a reaper that can be selectively used for walking work and riding work.

In conventional power reapers, the wheels of the riding device were of the rolling type, so in fields with soft terrain such as wet fields or semi-damp fields where running resistance is high, running resistance can be reduced by connecting the riding device. This increases significantly, making it impossible to run or causing an extreme drop in running performance.Also, in fields where the ground is sloping, the wheels on the riding equipment side will slide down the slope even if the ground is hard. Because of its strong tendency, it tends to meander when running, and therefore, although it can be used for riding, there are limits to the field conditions to which it can actually be applied.

In view of these points, the present invention has been developed to provide a power reaper that can smoothly, reliably, and safely travel in a riding mode, and has good steering performance, regardless of field conditions such as hardness, softness, slope, etc. It has a purpose in that it seeks to provide.

The power reaper according to the present invention is characterized in that, in the one described at the beginning, the wheels on the detachable riding device side are used as drive wheels.

That is, according to the present invention, by attaching and detaching the riding device from the main body, it is possible to easily switch between the riding work mode and the walking work mode. In addition, it is possible to suppress the decline in machine running performance due to the connection of riding equipment, so smooth and reliable running performance can be maintained even when riding on soft fields such as wet or semi-wet fields. Furthermore, even on a slope, meandering can be suppressed and sufficient straightness can be maintained, thereby expanding the field conditions in which a walking work mode and a riding work mode can be selected.

In other words, it has become possible to apply the riding mode to a wide range of fields.

Furthermore, the present invention uses low-pressure tires for the driving wheels to prevent the machine body from sinking in wet fields, etc., which occurs when a riding type machine is used, and also has a tube connecting device for connecting the riding device to the main body of the reaper. By creating a shaped frame and using it as a power transmission case from the main body to the driving wheels of the passenger equipment, we aim to reduce the weight of the entire passenger equipment, and furthermore, the driving wheels of the passenger equipment can be moved around the vertical axis passing through the rotation support shaft. The feature is that the reaper can be rotated integrally with the seat so that the interlining can be rotated.This greatly improves the steering performance, and it can be used in both wet and semi-wet fields, as well as in mountainous areas. Light work is now possible even in small fields.

In particular, when the riding device is connected to the reaper body so that it can freely swing up and down, the riding device can follow changes in ground irregularities while maintaining a constant body posture by vertically swinging the riding device. Even though the main body and riding equipment are in contact with the ground at two points, front and back, the main body can be held in a constant position regardless of changes in the unevenness of the ground, allowing for efficient reaping work. In addition, if a freely swingable passenger device is constructed so that it can be fixed in a fixed posture relative to the main body, the main body and the passenger device can be integrated and the vehicle can be driven on the road in a stable state where it touches the ground at two points, front and rear. can be done.

Hereinafter, an embodiment of the present invention will be described based on the drawings.A power harvester is equipped with a pair of left and right driving wheels 1, 1 using low-pressure tires. A processing section 6 that can be released laterally outward is arranged, and a driving section 7 for the running wheels 1, 1 pair and the processing section 6 is arranged at the rear of the running wheels 1, 1 pair, and A walking type reaper main body 3 comprising a steering handle 2 equipped with turning steering clutch operating levers 8a, 8a near the left and right pair of grips 2a, 2a, respectively, extending rearward and upward; 3, the riding device 5 is detachable from the rear portion of the vehicle and has one drive wheel 4 having a smaller diameter than the drive wheels 1, 1.

Incidentally, a bridge-like grounding body 6a is attached to the front part of the processing section 6, and supports the main body 3 by a pair of running wheels 1.

The riding device 5 is detachable from the main body 3, and
At the rear end of the cylindrical frame 5b having the riding step 5a,
The support frame 4a of the driving wheel 4 and the seat 5c are attached to each other, and the cylindrical frame 5b is attached to the main body 3 by using the section R as a support and swinging freely up and down with respect to the main body 3. and the cylindrical frame 5b.
is attached to the main body 3 by providing a set bolt 9 on the base end side for fixing the main body 3 in a fixed position.

The driving wheel 4 uses the driving portion 7 of the main body 3 as a driving source, and the transmission mechanism from the driving portion 7 to the driving wheel 4 is as follows:
It is internally installed in the cylindrical frame 5b and the wheel support frame 4a, and the input part of this transmission mechanism is interlocked with the output part on the main body 3 side as the cylindrical frame 5b is attached to and removed from the main body 3. It is possible to cancel the link.

Further, as shown in FIG. 1, the driving wheel 4 and the seat 5c are configured to be able to rotate integrally around a vertical axis X passing through the axis of the rotational support shaft y of the driving wheel 4. It is.

In the above configuration, by performing the reaping work with the connected riding device 5 in a free swinging state, the drive wheels 4 of the riding device 5 are moved up and down to follow changes in ground irregularities, and the driving wheels 1, 1 pair The state in which the main body is supported by the grounding body 6a, that is,
By making the posture of the main body 3 constant and fixing the connected riding device 5 in a constant posture, the main body 3 and the riding device 5 can be integrated, and the driving wheels 1, 1 pair and the driving wheel 4 can be connected at two points in front and behind. It is possible to drive on the road with the entire structure stably supported.

Further, by operating the steering clutch levers 8a, 8a, and rotating the seat 5c using the steering handle 2 and the step 5a as reaction force bases to turn the drive wheels 4, the vehicle can easily turn. Since the driving wheels 4 have a small diameter, turning resistance is small.
