An engine 15 is fixed to the lower side of the driver's seat 11, and an engine cover 17 is provided from the upper front side to the front side surface of the engine 15.
The structure protects the engine 15, and the driver's seat 11 is fixed to the upper surface.

Further, a step floor 19 on which the driver's feet can be placed is provided between the driver's seat 11 and the operation section.

As shown in FIG. 1, a cover 21 overlapping the rear end side of the engine cover 17 is fixed to the upper rear side of the engine 15, and a fuel tank 23 is placed and fixed on the cover 21. ing. A cover 25 is attached to the back side of the engine 15, and together with the engine cover 17 and the cover 21 described above,
An engine room 27 that houses the engine 15 is configured.

The inside of the right side surface of the engine room 27 is a radiator frame 29 that is vertically installed and fixed to the main body 2 side.
31 is fixed, and a box-shaped fan shroud 33 is further attached to the engine 15 side of the radiator 31. As shown in FIG. 3, the fan shroud 33 accommodates the tip side of the fan 35 attached to the engine 15, and
By the rotation of 35, the cooling air is forced to hit the radiator 31 from the outside.

A filter body 37 housed in a case 39 is fixed to the outside of the radiator 31. The filter body 37 is a porous body such as a sponge, and purifies the cooling air directed to the radiator 31 and performs sound insulation. The attachment position of the filter body 37 serves as an inlet for cooling air to the engine room 27.

On the outside of the right side surface of the engine room 27 described above,
The air guide portion 41 is attached. The air guide 41 is the outer cover 42
It is composed of a and an inner cover 42b and has a box shape, and guides cooling air from the outside of the main body 2 into the engine room 27.
An agitation separation chamber 45 is provided at a position corresponding to the engine room 27 of the air guide portion 41. Two first inlets 43 are formed on the front side surface of the stirring / separating chamber 45, and the cooling air blown from the first inlets 43 becomes a vortex when changing the direction to the engine room 27 and is mixed. It is separated from the remaining straw and dust and sucked into the engine room 27. The separated straw waste or the like is stored in a dust chamber 47 provided below the stirring / separating chamber 45.

At the position facing the filter body 37 of the inner cover 42b, the strainer net 4
9 is attached, and large pieces of straw and the like are removed by the strainer net 49.

As shown in FIG. 4, the air guide portion 41 is further provided with a stirring separation chamber.
It is formed so as to extend above 45 and reach above the fuel tank 23 so that the fuel tank 23 is hidden in a side view, and the projecting portion is provided with a second inlet 51 on the main body 2 side. By providing the second intake port 51, the first intake port 43 can be made smaller and the lateral width of the air guide portion 41 can be made narrower, so that it is possible to make the machine body width compact.

The second intake 51 is a ventilation filter made of punched metal
53 is stretched, and like the strainer net 49, prevents blowing of straw waste into the air guide portion 41. The ventilation filter 53 is provided with an insertion hole 55 into which an air introduction port 65 of an air cleaner 61 described later is inserted.

On the other hand, the air guide portion 41 is rotatably supported on the main body 2 side by a rotation fulcrum 57 at the lower end side. Since such a support structure is provided, as shown in FIG.
Can be pivoted away laterally. Further, since the engine cover 17 is integrally fixed to the air guide portion 41, the engine cover 17 is removed when the air guide portion 41 is removed, and the engine 15 is exposed.

As shown in FIGS. 1, 3, and 4, an air cleaner 61 is fixed to the upper rear portion of the engine 15 in the engine room 27. The air introduction pipe 63 of the air cleaner 61 penetrates through the cover 21, projects upward, extends rightward, and reaches the inside of the insertion hole 55. The tip of the introduction pipe 63 is opened to form an air introduction port 65. The leading end of the introduction pipe 63 is supported by an introduction pipe receiver 66 that is erected and fixed on the cover 21, and an elastic material 67 is fitted on the outer periphery of the air introduction port 65. Elastic material 67 is an insertion hole
When the introduction pipe 63 is inserted into the 55, the ventilation pipe 53 is brought into close contact with the ventilation pipe 53 to fill the gap between the insertion hole 55 and the introduction pipe 63, and the interference at the time of rotating and removing the air guide portion 41 is alleviated.

Air connection pipe between air cleaner 61 and engine 15
69 is provided and purified air is sent.

<Effect of the Invention> According to the structure of the present invention configured as described above, since the air cleaner is arranged in the engine room, the external appearance of the machine body is not damaged by the position and shape of the air cleaner.

In addition, since air is taken into the air cleaner from the second inlet on the upper side through the ventilation filter, for example, straw debris is less likely to be sucked in, and the effective use period of the air cleaner can be extended compared to the conventional case. There is an advantage that the maintenance frequency is reduced.
