Abstract

An attachment structure of a generator and a working machine including a transmission case; and a PTO shaft protruding from the transmission case, includes a structure body attached to a side of the transmission case from which the PTO shaft protrudes, and includes the generator attached to the structure body.

First claim

What is claimed is:

1. A structure body having a generator, comprising:
the structure body configured to be detachably attached to a traveling vehicle including: a transmission case; and a PTO shaft protruding from the transmission case; and
the generator attached to the structure body,
wherein the structure body includes:
a first portion to be attached to the transmission case;
a first attachment portion and a second attachment portion that constitute a second portion to which a working device is to be attached; and
a third portion to which the generator is attached, the third portion having a through hole for projecting the PTO shaft,

wherein the first attachment portion is arranged to one side in a vehicle width direction of the traveling vehicle,
wherein the second attachment portion is arranged to another side in the vehicle width direction,
wherein the third portion is formed of a rear plate that communicates between the first attachment portion and the second attachment portion,
wherein the rear plate is disposed ahead of a rear end of the first attachment portion and a rear end of the second attachment portion,
and wherein the generator is attached to the rear plate and is disposed between the first attachment portion and the second attachment portion.

2. The structure body according to claim 1 ,
wherein the generator is driven by a rotating power from the PTO shaft.

3. The structure body according to claim 1 ,
wherein the rotating power from the PTO shaft is divided into a first path and a second path by a power divider portion of the PTO shaft,
wherein the rotating power transmitted from the first path is outputted from the PTO shaft projecting from the through hole,
and wherein the generator is activated by the rotating power transmitted through the second path.

4. The structure body according to claim 1 , comprising
a first side plate and a second side plate arranged separately in the vehicle width direction,
wherein the generator is arranged between the first side plate and the second side plate in the vehicle width direction.

5. The structure body according to claim 4 , comprising
a first front plate and a second front plate attached to a rear surface of the transmission case,
wherein the first front plate is connected to a front end portion of the first side plate,
and wherein the second front plate is connected to a front end portion of the second side plate.

6. The structure body according to claim 1 ,
wherein the generator is arranged above the PTO shaft under a state where the structure body is attached to the transmission case.

7. The structure body according to claim 1 ,
wherein an output voltage of the generator is sixty volts or less.

8. The structure body according to claim 1 ,
wherein the traveling vehicle is a tractor.
