[Detailed description of the invention]

[0001]

The present invention relates to an agricultural work machine such as a rice transplanter or a tractor, more specifically, an engine is mounted on the front of the body, and a hood with head lamps mounted on the front is detachable from the body. It relates to the attached agricultural work machine.

[0002]

2. Description of the Related Art Conventionally, this kind of agricultural working machine has an engine and a battery mounted on a front upper part of the body, covers an outer periphery of the engine and the like with a bonnet, and electrically connects the battery to a front side of the bonnet. The headlamp is connected to the fuselage while the hood is removably attached to the fuselage side via a connection fitting, and between the fuselage and the hood, the hood is mounted at a predetermined position on the fuselage. Are provided. And in the case of performing repair inspection of the engine etc.,
By removing the bonnet from the fuselage side by the fixing release operation of the connection fitting, the engine or the like is opened to perform repair inspection work, and also, after completion of the repair inspection work and the like, via the alignment member. By performing the fixing operation of the connection fitting while positioning the hood at a predetermined position on the fuselage side, the bonnet is accurately attached to a predetermined position on the fuselage.

[0003]

However, in the above arrangement, a special positioning member is provided between the airframe and the hood to attach the hood removed from the airframe to a predetermined position on the airframe. Therefore, there is a problem that the number of parts increases and the cost increases, and the configuration becomes complicated.

In the present invention, a coupler having a lamp side connection portion and a power supply side connection portion for connecting a head lamp mounted on the bonnet to a battery is used between the body side and the bonnet. The purpose was to reduce the number of parts without using a special alignment member by performing alignment of the bonnet with respect to the fuselage side using each connection part of the coupler. Another object of the present invention is to provide an agricultural working machine that can accurately attach the hood to a predetermined position on the machine body with a simple configuration.

[0005]

In order to achieve the above object, the present invention provides a hood 4 having an engine 2 mounted on a front portion of a body 1 and a headlamp 41 mounted on a front portion.

And one of the lamp-side connecting portion 11 and the power-side connecting portion 12 is formed into a male shape and the other is formed into a female shape, and a guide portion 13 for guiding the hood 4 to the body 1 is provided between the connecting portions 11 and 12. It was formed.

[0006]

In the above-mentioned agricultural work machine, when repair work of the engine 2 and the like is performed, the lamp side connection portion 11 provided on the hood 4 is connected to the power supply side connection portion 12 provided on the machine body 1 side. By detaching and removing the hood 4 from the fuselage 1, the engine 2 and the like are opened to the outside and repair and inspection thereof are performed. After the repair and inspection work is completed, the hood 4 is attached to a predetermined position on the body 1 side. At this time, the lamps and the power supply side connection portions 11 and 12 are attached to the hood 4 and the body 1. Together with these connecting parts 11, 1
2 has a shape of either male or female.
Since the guide portion 13 for guiding the hood 4 to the body 1 is formed between the two, the lamp side connection portion 11 is connected to the power supply side connection portion 12 so that the hood 4 4 is accurately aligned with the fuselage 1 side.
Can be accurately attached to a predetermined position on the body 1 side.
Further, in the above configuration, the guide portion 13 is formed using the lamp side connection portion 11 and the power supply side connection portion 12 for connecting the head lamp 41 mounted on the hood 4 to the battery 3. The positioning of the bonnet 4 with respect to the body 1 is performed via the guide portion 13, so that the hood 4 can be accurately attached to the body 1 with a small number of parts and with a simple configuration.
