DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riding agricultural working machine such as a tractor having a working machine such as a rotary tilling device mounted rearward.

[0002]

2. Description of the Related Art Conventionally, a riding agricultural machine such as a tractor having a working machine such as a rotary tilling device mounted rearward is configured such that a traveling system and the working machine are driven by power transmitted from an engine.

[0003]

When the traveling system and the working machine are driven by the engine as described above, noise and vibration of the engine are increased, and a large amount of exhaust gas is generated. Driving near urban areas can lead to environmental problems. Accordingly, an object of the present invention is to provide a riding agricultural machine capable of suppressing generation of noise, vibration, and exhaust gas during traveling.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention provides the following riding agricultural working machine. That is, in a riding agricultural work machine such as a tractor equipped with a work machine on the rear side, the work machine is configured to be directly driven by the power taken out from the engine, and the generator is driven to store power in the battery and is driven by the power. A riding farm working machine characterized in that a running system is driven by an electric motor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below based on examples shown in the drawings. FIG. 1 is a schematic side view showing a small tractor as an example of a riding agricultural working machine. This tractor raises and lowers a rotary tilling device (2) as an example of a working machine at the rear of a self-propelled traveling vehicle (1). Wearing freely.

[0006] A steering handle (3) is provided at the front of the traveling vehicle (1), and a driver's seat (4) is provided behind the steering handle (3). An engine (5) is provided behind the driver's seat (4), and a transmission section (6) is provided below and in front of the engine (5). Front wheel (7)
Is mounted via a front axle (not shown), and the rear wheel (8) is mounted via a rear axle (8a).
And then the axle (8a) is the rear axle transmission case (9)
The power from the transmission unit (6) is transmitted to the rear axle (8a) via the transmission shaft case (10) and the rear axle transmission case (9) so that the rear wheel (8) is driven. It has become.

A brake lever (12) is disposed on the left side of the steering column (11) of the steering handle (3), and a PTO clutch lever (13) is disposed on the right side. A main shift lever (14) is disposed on the left side of the driver's seat (4), and a lifting operation lever (15) for raising and lowering the rotary tillage device (2) and a rotary tillage device (2) are provided on the right side. An operation lever (16) for engaging and disengaging the clutch and an operation lever (17) for adjusting the working depth are provided. Further, a roll bar (18) having a portal shape in a front view is provided upright behind the driver's seat (4).

A PTO shaft (19) for transmitting power from the engine (5) to the rotary tilling device (2) is laid on the lower rear end of the traveling vehicle (1), and a rotary tilling is mounted on the upper rear end. A lift cylinder (20) for raising and lowering the device (2) is provided. The rotary tilling device (2) is connected to the rear of the traveling vehicle (1) by a hitch (21), and power from the PTO shaft (19) is transmitted to the transmission case (22), and the tilling claw shaft (23). , And a rotary tilling claw (not shown) is rotationally driven to perform tilling work. (24) is a rotary cover, and (25) is a rotating rear cover.

Next, the power transmission mechanism of the tractor as described above will be described. As shown in FIG.
The tractor according to the present invention is provided with a generator (30) driven by power taken from the engine (5), a battery (31) for storing electricity generated by the generator (30), and the battery (31). An electric motor (32) driven by the electric power stored in the
A controller (33) for controlling them is provided. The rotary tiller (2) is driven directly by the power taken out of the engine (5), and the rear wheel (8) is driven by the electric motor (32). .

That is, the electric motor (32) is driven by the electric power stored in the battery (31), and power is transmitted from the electric motor (32) to the transmission section (6) by the transmission belt (28). 6) to drive the rear wheel (8) as described above, and to transfer the power taken out from the engine (5) to the power transmission belt (29).
, And is transmitted directly to the PTO shaft (19) to drive the rotary tilling device (2).

[0011] According to such a configuration, the engine can be stopped except during work, so that the conventional noise problem does not occur. That is, since the vehicle can be driven by electric power during traveling, the generation of noise, vibration, and exhaust gas can be suppressed, and the vehicle can travel comfortably. In addition, charging can be performed during the work, so that the efficiency is high, and since the drive system of the work machine and the traveling system of the vehicle are independent of each other, a load is applied to the work machine, that is, a load is applied to the engine. The controller can also control the electric motor quickly, making it easy to adjust the running speed and reduce the load on the engine.

[0012]

As described above, according to the present invention, in a riding agricultural working machine such as a tractor having a working machine mounted on the rear side, the working machine is directly driven by the power taken out of the engine and the generator is driven. The battery is stored in the battery, and the running system is driven by an electric motor driven by the power, so the engine can be stopped except during work, generating noise, vibration and exhaust gas during running. Can be suppressed.
