DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
1 to 4 show a six-row planting rice transplanter as an example of a traveling vehicle, and a pair of left and right front wheels 2 and 2 and rear wheels 3 and 3 serving as traveling wheels are installed before and after the vehicle body 1. ing. A steering post portion 6 having an operation box 4 and a steering handle 5 etc. is erected above the step floor 7 at the front upper portion of the vehicle body, and a working device constituted by a seedling planting portion 8 is provided at the rear portion of the vehicle body as a lifting link mechanism. 9 is installed to be movable up and down. A driver's seat 11 is installed on the rear side of the steering post 6 at the upper end of a driver's seat support 10 that protrudes above the step floor 7, and transmits power to each part of the rice transplanter below the driver's seat 11. An electric motor 13 that assists the driving of the engine 12 and the vehicle is mounted.
[0011]
On the steering post portion 6 side, a battery 14 for starting the engine 12 and driving the electric motor 13 is housed. Further, a fuel tank 15 for the engine 12 can be provided in the steering post portion 6.
The seedling planting unit 8 (working device) includes a seedling mounting tank 16 that reciprocates left and right, a planting device 17 having a planting basket that cuts out seedlings for one stock and transplants them into the soil, and a seedling planting surface. It consists of a leveling float 18 or the like.
[0012]
The motor 13 is connected to the output shaft 19 of the engine 12 through a one-way clutch 20 in an interlocking manner.
The traveling mission device 21 is disposed below the step floor 7 on the front side of the vehicle body 1 so that the rotational power input from the engine 12 is transmitted to the left and right front wheels 2 and 2 and the left and right rear wheels 3 and 3. 22 is equipped.
[0013]
The main clutch device 23 includes a transmission belt 23a provided between the output shaft 19 of the engine 12 and the intermediate input shaft 24 of the traveling mission device 21, a belt tension type clutch 23b that tensions / relaxes the transmission belt 23a, and the clutch The main clutch lever 23 is operated intermittently.
[0014]
The auxiliary transmission 25 includes a Belcon-type continuously variable transmission belt 25a, a tension pulley 25b, and an auxiliary transmission lever 25c provided between the intermediate input shaft 24 and the input shaft 26 of the mission case 22. By operating the auxiliary transmission lever 25c, the input shaft 26 is continuously variablely transmitted to a low speed, a medium speed, and a high speed.
[0015]
In the traveling vehicle in such an embodiment, the first prime mover (engine 12) is always driven as the main power during work, and when a traveling load or work load exceeding a certain level is applied, the second prime mover (motor 12) according to the load. -It is set as the structure which assists the driving force of the 1st motor | power_engine 12 by driving the data 13) .
[0016]
[0017]
[0018]
In the second example, the motor is always driven by the prime mover (engine 12) during operation during normal rice transplanting work, and when the traveling speed during work is shifted to a high speed side by a predetermined value or more, the other prime mover ( The driving force is assisted by driving the motor 13). That is, for example, the engine 12 is always driven as the main power during planting work, and the motor 13 is driven when the sub-shift lever 25c is shifted to a certain level, for example, from a medium speed to a high speed. The driving force of the engine 12 is assisted by driving the motor 13.
[0019]
In the third example, a traveling vehicle that travels by driving a plurality of prime movers 12 and 13 is configured to always be driven by a prime mover on one side, for example, the engine 12, during normal travel. When the inclination posture of the aircraft changes more than a predetermined value, that is, when the inclination posture of the fuselage greatly changes back and forth or left and right, the inclination sensor 29 detects this, and based on the detection result by the inclination sensor 29, the motor on the other side, for example The motor 13 is interlocked so as to be driven, and the motor 13 is driven to assist in increasing the driving force by the engine 12. Therefore, when the airframe is greatly inclined, the inclined wheel sinks and receives a large traveling load. This can be assisted by driving the motor 13.
[0020]
In the fourth example, in a traveling vehicle that drives a vehicle by driving a plurality of prime movers, when one of the plurality of prime movers is an engine 12 and the governor 30 of the engine 12 operates more than a certain level. The other motor, for example, the motor 13 is driven to assist in increasing the driving force of the engine 12. In other words, during operation, when the engine load increases and the governor 30 operates over a certain level, a sensor is provided to detect this, and the motor 13 is driven so as to drive based on the detection result by this sensor. is there.
[0021]
In addition, when the accelerator lever (accelerator pedal) 31 interlocked with the governor 30 is operated to the engine rotation speed increasing side for a predetermined time or more, the motor 13 that is the second prime mover can be driven.
