Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to heat shielding for an operation panel in a combine and efficient muffler cooling.
More specifically, the present invention relates to a driving unit structure of a combine in which a driver's seat is disposed on an upper surface of a driving unit, and an operation panel connected to the driving unit is disposed beside the driver's seat.

[0002]

2. Description of the Related Art As a combine of this kind, Japanese Utility Model No. 3
As shown in JP-A-91225, an engine room extending to the side of the operation panel is formed in a driving portion below the driver's seat, and the engine and the engine are arranged to prevent the temperature of the driver's seat and the operation panel from rising. A relatively large space was provided above the muffler.

[0003]

[Problems to be Solved by the Invention] By the way, when the size of the engine is increased in order to improve the output and improve the overall performance as a combine, the muffler is arranged vertically at the rear side of the engine as in the prior art. Difficult to do,
In addition, since the extra space above the engine also becomes narrow, it is expected that thermal conditions will be severe in the prime mover structure following the conventional configuration. In order to solve this problem, it is conceivable to increase the size of the prime mover itself, but this is not preferable because it increases the size of the body. An object of the present invention is to fundamentally review the layout of the driving unit so that the thermal conditions due to the enlargement of the engine can be cleared while keeping the size of the driving unit itself unchanged.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an operation system in which a driver's seat is arranged on the upper surface of a driving unit and is connected to the driving unit beside the driver's seat. In the prime mover structure of the combine where the panel is arranged, a muffler is arranged above the engine in the prime mover, and a heat shield member for the operation panel is installed above the muffler, and the lateral position of the aircraft inside the prime mover A guide that guides the wind of the cooling fan between the heat shield member and the muffler so that the wind generated by the radiator cooling fan disposed in the air passage passes between the heat shield member and the muffler A plate is provided.

[0005]

[Function] Due to the increase in the exclusive space in plan view accompanying the enlargement of the engine, the muffler cannot be arranged vertically as in the past, and it is also difficult to arrange the muffler below the fuselage from above the fire protection. The muffler is disposed above the engine. However, since the muffler is disposed in a space above the engine, which has less room than before, the thermal conditions are considerably severe.

[0006] In the operation panel having a structure connected to the driving unit, the temperature rise is particularly noticeable as compared with the driver's seat, which is a separate member from the components of the driving unit. In addition to the heat shielding effect provided by the heat member, a scavenging effect also occurs by providing a guide plate and actively passing the air of the cooling fan between the muffler and the heat shielding member, thereby increasing the temperature of the operation panel. Is effectively prevented, and the muffler is brought sufficiently close to the heat shielding member side so as to effectively utilize the space in the driving part, and also, it is possible to prevent the hot air from remaining in the upper part in the driving part.

[0007] Since the means for generating the scavenging action uses a cooling fan originally provided, it is also advantageous that it is not necessary to provide a separate device for generating wind.

[0008]

[Effects of the Invention] Therefore, by reviewing the layout in the driving unit and effectively utilizing the air of the cooling fan with the guide plate, it becomes the basis for heat shielding for the operation panel, effective use of the space in the driving unit, and improvement of the combine performance. It was possible to increase the size of the engine to achieve higher output without increasing the size of the driving part and clearing the thermal conditions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a side view of the combiner, and FIG. 1 is a rear view of the driving unit. 1 is a driving unit, 2 is an engine, 3 is a driver's seat, 4 is an operation panel, 5 is a step floor, 6 is a muffler, 7 is an air cleaner.

The engine room R extends between the inside of the driving unit 1 and the inside of the operation panel 4, and a muffler 6 is arranged just below the operation panel 4 located to the left of the driver's seat 3. A dust-proof grill 8 is provided on the right side wall 1A of the prime mover 1, which is the right end of the body, serves as a cooling air intake, and a radiator 9 and a cooling fan 10 are arranged on the inner surface side. 11 is an oil cooler.

The elliptical cylindrical muffler 6, which is long in the front and rear directions, has a vertically split structure formed by a press plate. A rightwardly obliquely downwardly directed guide plate 12 is attached to the right side welding flange 6a. An air cleaner 7 having a cylindrical shape is arranged at a position close to the upper right side.

Below the operation panel 4, there are provided a heat-shielding plate (corresponding to a heat-shielding member) 14 extending obliquely in the horizontal direction, and heat-insulating plates 13 in the form of vertical plates above and below the heat-shielding plate.
And space k ₁ between the guide plate 12, air passage W becomes a space k ₂ is the cooling exhaust air by the cooling fan 10 between the muffler 6 and the heat shield plate 14, the radiation heat generated by the engine 2 and the muffler 6 It can be wiped out by cooling exhaust air (wind speed 5m / s or more).

That is, the wind of the cooling fan 10 is directed between the heat shielding member 14 and the muffler 6 so that the wind generated by the cooling fan 10 passes between the heat shielding member 14 and the muffler 6. The guide plate 12 is provided to guide the heat, and the heat of the muffler 6 can be quickly discharged out of the machine by a scavenging action.

The scavenging action in the engine room R can prevent the top plate 1B and the operation panel 4 of the prime mover 1 from becoming hot, and also allow the cooling exhaust air to pass below the air cleaner 7 to cool the air cleaner 7. Is also suppressed, which contributes to an improvement in the charging efficiency of the engine 2.
