細かい塵芥等の清掃を迅速に行うことができる。[Function] For example, after connecting a mower to the front of the work vehicle and then starting the engine, the work vehicle is driven toward the embankment or the flat grassland where the grass is dense, and the dense grass is quickly removed. Is cut by a mower. By the way, during the mowing operation as described above, dust and fine dust scattered and floated around are sucked into the engine cooling radiator together with the cooling air by the suction of the fan, causing a clogging phenomenon, and the engine is overheated, Normal operation cannot be performed, and good mowing work cannot be performed. However, in the present invention, the upper horizontal suction duct and the vertical suction duct are provided on the rear side of the protective frame provided on the chassis to prevent the worker from being placed under the work vehicle when the work vehicle falls down. The upper horizontal suction duct has an open air suction window facing downward, and the outer air discharge window opened at the bottom of the vertical suction duct has a front side of the engine cooling radiator provided on the chassis. It is possible to set the opening position of the outside air suction window at the highest position of the work vehicle without using any special member, even if dust and fine dust are scattered and floating. However, the higher the height, the smaller the amount in inverse proportion to the height due to the action of gravity (attraction), so that only the outside air for cooling is sucked through the outside air suction window, and dust and fine dust are sucked in. It can be prevented in advance. Therefore, even if mowing or other work is continued, only the outside air for cooling supplied to the engine cooling radiator is sucked into the outside air suction duct, so that the engine cooling radiator is cooled without being clogged and the engine is cooled. Can be operated normally, and efficient mowing can be performed. In addition, since the dust-proof mesh plate is freely detachable from the outside air suction window that opens downward, even if there is dust or fine dust scattered and suspended to the height of the outside air suction window, the outside air suction Not only can it be reliably prevented from being sucked into the outside air suction duct from the window, but also dust and fine dust attached to the surface of the dust-proof mesh plate can be quickly cleaned.

簡単に引き抜いて清掃することができる。Since the present invention is configured as described above, the following effects are obtained. An external air suction duct is provided by effectively using the gate-type protective frame provided on the chassis so that the worker does not fall under the work vehicle when the work vehicle falls, and the cooling air is sucked into the engine cooling radiator. The outside air suction duct is formed by an upper horizontal suction duct and a vertical suction duct, and the upper horizontal suction duct has a downward opening of the outside air suction window. Dust and fine dust that are scattered and floated around at the highest position are sucked into the outside air suction duct from the outside air suction window, preventing clogging of the engine cooling radiator and preventing the engine from overheating. And normal operation can be continued for a long period of time to achieve efficient work. In addition, in the present invention, since the dust-proof net body is disposed in the outside air suction window so that it can be freely inserted and removed, is it possible to further clean the outside air sucked from the outside air suction window,
If the dust net is clogged with dust or fine dust,
It can be easily pulled out and cleaned.
