Abstract

A work management system includes a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven by power transmitted from a PTO shaft, and configured to transmit power to a working device provided in the working machine, an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator, a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion, and a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion.

First claim

What is claimed is:

1. A work management system comprising:
a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven by power transmitted from a PTO shaft, and configured to transmit power to a working device provided in the working machine;
an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator;
a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion;
a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion; and
a motor configured to be driven by the power from the generator,
wherein the working device has
a rotor to be turned by power from the motor to spread a spread substance,

and wherein the controller portion controls a rotating speed of the rotor based on the operation information.

2. The work management system according to claim 1 , comprising:
a height detector device configured to detect a height of the rotor from ground; and
a height adjuster mechanism configured to adjust the height of the rotor based on the height detected by the height detector device,
wherein the information obtaining portion obtains, as the operation information, height information relating to the height detected by the height detector device,
and wherein the controller portion controls the rotating speed of the rotor based on the height information obtained by the information obtaining portion.

3. The work management system according to claim 1 , comprising:
a vehicle-speed detector device configured to detect a traveling speed of the working machine,
wherein the information obtaining portion obtains, as the operation information, vehicle-speed information relating to the traveling speed detected by the vehicle-speed detector device,
and wherein the controller portion controls the rotating speed of the rotor based on the vehicle-speed information obtained by the information obtaining portion.

4. The work management system according to claim 1 , comprising:
a power transmission mechanism configured to transmit, to the working device, the power from the PTO shaft and the power from the motor; and
a PTO shifter portion configured to change the rotating speed of the PTO shaft,
wherein the controller portion transmits a control signal to the PTO shifter portion to shift the PTO shaft, thereby controlling the rotating speed of the rotor.

5. The work management system according to claim 1 , comprising:
a posture detector device configured to detect a posture of the working device; and
a posture adjuster mechanism configured to adjust the posture of the working device based on the posture detected by the posture detector device,
wherein the information obtaining portion obtains, as the operation information, posture information relating to the posture of the working device detected by the posture detector device,
and wherein the controller portion controls the rotating speed of the rotor based on the posture information obtained by the information obtaining portion.

6. The work management system according to claim 1 , comprising:
a position detector device configured to detect a position of the working device,
wherein the information obtaining portion obtains, as the operation information, position information relating to the position of the working machine detected by the position detector device,
and wherein the controller portion controls the rotating speed of the rotor based on the position information obtained by the information obtaining portion.

7. The work management system according to claim 1 , comprising:
a wind-speed detector device configured to detect a speed and direction of wind received by the working device,
wherein the information obtaining portion obtains wind-speed information relating to the speed and direction of the wind detected by the wind-speed detector device,
and wherein the controller portion controls the rotating speed of the rotor based on the wind-speed information.

8. The work management system according to claim 1 ,
wherein the work management portion has
a display device to display the operation information.

9. The work management system according to claim 1 ,
wherein the structure body is a coupler device configured to be coupled to the working device that is driven by the power transmitted from the PTO shaft.

10. The work management system according to claim 9 ,
wherein the coupler device has:
a first portion configured to be attached to the transmission case;
a second portion to which the working device is attached; and
a third portion to which the generator is attached, the third portion having a through hole from which the PTO shaft protrudes under a state where the first portion is attached to the transmission case.

11. A work management system comprising:
a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven by power transmitted from a PTO shaft, and configured to transmit power to a working device provided in the working machine;
an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator;
a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion; and
a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion,
wherein an output voltage of the generator is sixty volts or less.

12. A work management system comprising:
a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven independently from a PTO shaft, and configured to transmit power to a working device provided in the working machine;
an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator;
a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion;
a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion; and
a motor configured to be driven by the power from the generator,
wherein the working device has
a rotor to be turned by power from the motor to spread a spread substance,

and wherein the controller portion controls a rotating speed of the rotor based on the operation information.
