Abstract

An apparatus and a system directed to a towed device powered by a tow vehicle. The apparatus and system include a woodchipper configured to be mounted on a towed vehicle, with the towed vehicle configured to be towed behind the tow vehicle. Additionally, a motor may be coupled to the woodchipper to provide power to the woodchipper. A power converter obtains power from the tow vehicle from a power takeoff coupled to the tow vehicle. Further, one or more power transfer lines connect the power converter with the motor to communicate motor-operating power from the power converter to the motor.

First claim

Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1. An engineless woodchipper system for powering a woodchipper with a tow vehicle, comprising:
a woodchipper configured to be mounted on a towed vehicle, wherein the towed vehicle is configured to be towed behind the tow vehicle,
wherein the tow vehicle and the towed vehicle are configured to operate on a highway at highway speeds;
an electric motor coupled to the woodchipper and operable to provide power to a cutting mechanism of the woodchipper;
a power takeoff coupled to the tow vehicle and operable to obtain mechanical power from the tow vehicle;
a power converter engaged with the power takeoff, wherein the power converter is configured to convert the mechanical power obtained by the power takeoff into a motor-operating power operable to power the motor attached to the woodchipper; and
one or more power transfer lines connecting the power converter with the motor and operable to communicate the motor-operating power from the power converter to the motor.

2. The engineless woodchipper system of claim 1 , wherein the motor is further operable to power auxiliary components of the woodchipper, including one or more of the following: a feed roller, a lift cylinder, and a discharge chute.

3. The engineless woodchipper system of claim 1 , wherein the electric motor is selected from a variable output motor or a fixed output motor.

4. The engineless woodchipper system of claim 1 , wherein the electric motor includes a control system for controlling a speed of the motor.

5. The engineless woodchipper system of claim 1 , wherein the electric motor includes a control system for controlling a torque of the motor.

6. The engineless woodchipper system of claim 1 , wherein the electric motor includes a control system for controlling a direction of the motor.

7. The engineless woodchipper system of claim 1 , wherein the power converter is an electric generator.

8. The engineless woodchipper system of claim 7 , wherein the electric generator includes a control system for controlling an output of the electric generator.

9. The engineless woodchipper system of claim 1 , wherein the one or more power transfer lines are electric cables.

10. An engineless woodchipper system for powering a woodchipper with a tow vehicle, comprising:
a woodchipper having a cutting mechanism configured to be mounted on a towed vehicle, wherein the towed vehicle is configured to be towed behind the tow vehicle,
wherein the tow vehicle and the towed vehicle are configured to operate on a highway at highway speeds;
an electric motor coupled to the woodchipper and operable to provide power to a cutting mechanism of the woodchipper;
a power takeoff coupled to the tow vehicle and operable to obtain mechanical power from the tow vehicle;
an electric generator engaged with the power takeoff, wherein the electric generator is configured to convert the mechanical power obtained by the power takeoff into electrical power operable to power the electric motor attached to the woodchipper; and
one or more power electric cables connecting the electric generator with the electric motor and operable to communicate the electrical power from the electric generator to the electric motor.

11. The engineless woodchipper system of claim 10 , wherein the electric motor includes a control system for controlling a speed of the motor.

12. The engineless woodchipper system of claim 10 , wherein the electric motor includes a control system for controlling a torque of the motor.

13. The engineless woodchipper system of claim 10 , wherein the electric motor includes a control system for controlling a direction of the motor.

14. The engineless woodchipper system of claim 10 , wherein the electric generator includes a control system for controlling an output of the electric generator.

15. An engineless woodchipper system configured to power a woodchipper with a tow vehicle, comprising:
a woodchipper having a cutting mechanism;
an electric motor configured to be coupled to the woodchipper and operable to provide power to a cutting mechanism of the woodchipper;
a power converter configured to be engaged with a power takeoff of the tow vehicle, wherein the power converter is configured to convert mechanical power obtained by the power takeoff into a motor-operating power operable to power the motor attached to the woodchipper; and
one or more power transfer lines connecting the power converter with the motor and operable to communicate the motor-operating power from the power converter to the motor.

16. The engineless woodchipper system of claim 15 , wherein the motor is further operable to power auxiliary components of the woodchipper, including one or more of the following: a feed roller, a lift cylinder, and a discharge chute.

17. The engineless woodchipper system of claim 15 , wherein the electric motor is selected from a variable output motor or a fixed output motor.

18. The engineless woodchipper system of claim 15 , wherein the electric motor includes a control system for controlling one or more of the following: a speed of the motor, a torque of the motor, and a direction of the motor.

19. The engineless woodchipper system of claim 15 , wherein the power converter is an electric generator that includes a control system for controlling an output of the electric generator.
