Description

[Detailed description of the invention] This invention places the engine in a room formed below the driver's seat with cooling airflow flowing sideways, and a cover with ventilation holes that covers the front of the engine room. The present invention relates to an engine heat insulation structure for a power mobile agricultural machine, in which a heat shielding cover is configured to be openable/closed or detachable, and a heat shielding cover is disposed in the engine room at an appropriate distance from the engine side with respect to the cover.

This type of engine heat insulation structure has the effect of blocking the side radiation heat of the engine by the heat shield plate, and the cooling effect by sucking outside air from the vent through the ejector effect accompanying the flow of engine cooling air. This system is designed to suppress an abnormal rise in the ambient temperature near the driver's feet through synergy.However, in the past, the heat shielding cover was constructed from a rigid cover such as a sheet metal, so it was difficult to check the oil. Since it is necessary to be able to perform maintenance around the engine such as replacing elements and adjusting belts at any time, the heat shield cover itself must be constructed so that it can be opened and closed or detached. The drawback was that it not only became more complicated, but also made maintenance work around the engine more laborious and complicated.

In view of the above-mentioned circumstances, the purpose of the present invention is to enable quick and easy maintenance of the engine area without complicating the overall structure. The above-mentioned device is characterized in that the heat shielding cover is constituted by a flexible hanging cover.

That is, since the heat shielding cover is a flexible hanging cover that can be flipped up freely from the heat shielding position, maintenance around the engine such as oil inspection and oil element replacement can be carried out. At times, it is only necessary to open/close or attach/detach only the outer cover, making the overall structure simpler than the conventional structure and allowing maintenance work to be performed quickly and easily.

In addition, if cuts of appropriate length are formed from the bottom edge of the heat shielding sagging cover at multiple locations in the width direction, maintenance can be done by simply flipping up only the cover portions that are necessary for maintenance. Preparation work for this purpose can be streamlined and facilitated, and furthermore, a locking tool is provided that can lock and hold each cover section divided by the notch individually in a flipped-up position. In this case, it is not necessary to turn up the cover portion one by one by hand and hold it in the posture, and maintenance work can be facilitated.

Hereinafter, an embodiment of the present invention will be described based on the drawings. A planted grain culm is raised on the front part of a machine frame 3 equipped with a pair of left and right crawler running devices 1, 1 and a threshing device 2, and after being harvested. A reaping section 4 for conveying and supplying this to the threshing device 2 is connected and supported so that it can be driven up and down,
An engine equipped with a cooling radiator 7 and a fan 8 is mounted on the machine frame portion protruding from one side of the reaping section 4 and within an engine room R6 configured with a support frame 6 for the driver's seat 5. 9 is supported in a state in which the cooling airflow flows sideways, that is, in a state in which the radiator 7 is located on the lateral outer side of the engine 9 and in a vertical vibration damping state, and the engine cooling air flow in the radiator 7 is On the upper side in the direction, that is, on the lateral outer side, there is an intake duct 11 having a dustproof net 10 stretched over the cooling air inlet to the radiator 7, and a swing opening/closing and closing posture with respect to the driver's seat support frame 6. A decorative cover 12 with a ventilation hole 12a that can be fixed freely is provided, and among the covers 13, 14, and 15 that cover the front, rear, and upper parts of the radiator 7 and the engine 9, a decorative cover with a ventilation hole 13a located in the front part is provided. cover 13
is configured to be detachably attached to the driver's seat support frame 6, and a heat shielding cover 16 is further provided between the front decorative cover 13 and the engine 9 in the engine room R. In the engine heat-insulating structure, the heat-insulating cover 16 is constituted by a flexible hanging cover, and cuts 17, 17 of an appropriate length are formed at two locations in the width direction of the hanging cover 16 from the lower end side thereof. Each cover portion 1 partitioned by these cuts 17, 17
6a... are configured to be able to be turned up freely relative to other cover portions 16a..., and furthermore, these cover portions 16a... The U-shaped locking tools 18A and the hook-shaped locking tools 18B can be individually locked and held in the above-mentioned flipped up position.
and.

Furthermore, a bearing member 20 is provided in which a supporting shaft 19 is loosely fitted to a portion of the intake duct 11 located near the lower end of the rear portion of the radiator 7, and is positioned along the left and right lateral directions.
A swing type dust remover 21, 21 is fixed to the outside of the support shaft 19 so as to be rotatable therethrough, and has dust removal brushes 21a, 21a that slide into contact with both the front and back surfaces of the dustproof net 10, respectively. , the arm 22 fixed to the inner end of the support shaft 19 and the arm 24 on the side of the main clutch pedal 23 provided at a position displaced forward of the radiator 7 are moved as the main clutch pedal 23 is depressed and released. Both dust removers 19, 19 are linked together via a rod 25 in order to forcibly swing the dust removers 19, 19 by pushing and pulling.

In the figure, 26 is an oil element, 27 is an oil dipstick, and 28 is a bolt for adjusting the tension of the fan belt 29.

Further, the front decorative cover 13 may be configured to be fixed to the driver's seat support frame 6 in swinging opening/closing and closing positions.
