Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural work vehicle such as a riding lawn mower or a tractor, and more particularly to a control panel for an agricultural work vehicle having an outside air intake provided on a control panel connected to a rear portion of an engine bonnet.

[0002]

2. Description of the Related Art Conventionally, a control panel of an agricultural work vehicle has been provided with a control panel according to the type of engine mounted on the body, that is, the type of engine such as an air-cooled engine or a water-cooled engine
It used a control panel with an outside air intake suitable for them.

That is, in the case of an air-cooled engine, since the amount of intake air is small, that is, the suction force is weak, the outside air intake provided with a grid-shaped crosspiece capable of preventing the entry of large straw chips. In the case of a water-cooled engine using a control panel equipped with, the intake air volume is large, that is, the suction force is strong. Therefore, a control panel equipped with an outside air intake provided with a dustproof net is used.

Therefore, depending on the type of engine mounted on the machine body, it is suitable for an engine mounted on the machine body, such as a control panel having grid-shaped crosspieces or a control panel having a dustproof net. I was using the control panel.

[0005]

According to the above-mentioned conventional technical means, it is necessary to prepare two types of control panels according to the types of engines mounted on the machine body, which is uneconomical. There is an inconvenience that causes high cost.

A first object of the present invention is to reduce the cost by making the control panel also used.

A second object of the present invention is to facilitate cleaning of the dustproof net and improve its durability.

[0008]

According to a characteristic configuration of the first aspect of the present invention, a crosspiece for subdividing the outside air intake is provided at the outside air intake of the control panel, and around the outside air intake,
The point is that a dust-proof net mounting part is provided.

The feature of the second aspect of the present invention resides in that the dust-proof net attached to the dust-proof net attachment portion is attached to the outer surface of the crosspiece.

[0010]

According to the characterizing feature of the first aspect of the present invention, the dust net is attached to or removed from the outside air inlet provided with the crosspiece according to the type of the engine mounted on the machine body. That is, in the case of a water-cooled engine, a dust-proof net is attached to prevent the suction of large straw dust, and in the case of an air-cooled engine, the dust-proof net is removed to secure the amount of cooling air.

According to the characterizing feature of the second invention, by mounting the dustproof net on the outside, the crosspiece obstructs the dust when removing the dust adhering to the dustproof net from the outside as compared with the case of mounting the dustproof mesh on the inside. Moreover, when an external force such as a knee acts on the dustproof net, the inward recess of the dustproof net can be suppressed by using the crosspiece.

[0012]

According to the first aspect of the present invention, the same control panel can be used regardless of the type of engine mounted on the machine body, and the cost of the control panel can be reduced.

According to the second aspect of the present invention, the dustproof net can be easily cleaned from the outside without interfering with the crosspiece, and the crosspiece can be used to suppress the deformation of the dustproof net to the inside.
The durability of the dustproof net can be improved.
