Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combine harvester in which an engine whose upper part is covered with a cover is disposed near a threshing device.

In this type of combine harvester, the engine is placed near the threshing equipment as mentioned above, so the upper part of the engine is covered with a cover to protect it. Dust blown out from openings such as the culm supply port and straw debris falling from the conveyor culm are likely to accumulate, and if the accumulated dust is left as it is, there is a risk of a fire outbreak.

In view of the above-mentioned circumstances, the present invention is designed to reliably and smoothly remove accumulated dust particles that can cause fires by effectively utilizing the cooling air for cooling the engine. , which has been officially registered, is characterized in that a guide plate 11 is provided for discharging cooling air after cooling the engine along the outer surface of the cover.

As a result, even if dust particles such as dust blown out from openings such as the husk supply port of the threshing device or straw debris falling from the conveyor culm try to accumulate on the engine cover, this could be the cause of the fire. It has now become possible to reliably and smoothly exhaust the dust particles to the outside by effectively utilizing the cooling air after cooling the engine.

Further, since the cooling air is discharged along the outer surface of the cover by the guide plate, the outer surface of the cover is constantly exposed to the flowing cooling air, and cooling of the cover is greatly promoted.

Therefore, there is an advantage that the hot air trapped inside the cover can be effectively dissipated to the atmosphere.

Embodiments of the present invention will be described below based on the drawings.

The drawing shows a walk-behind combine harvester to which the present invention is applied, which has a puller that engages with the stock base of two planted culms near the ground in front of the clipper-type reaping device 1 and pulls it rearward and upward for transport. The threshing device 2 is connected to a threshing device 5 mounted on a machine frame 4 having a crawler-type traveling device 3, and the threshing device 5 is used to feed threshing while gradually changing the posture of the husks that have been harvested in a vertical position to a sideways posture. An engine 9 having a cooling fan 8 is disposed on the side of the machine opposite to the vertical transport device 7 that supplies the chain 6, with the axis of its power take-off shaft 9A oriented along the direction of movement of the machine. The engine 9 is cooled by a cover 10 covering the upper part of the engine 9, the fuselage frame 4, a front plate 5A of the threshing device 5, and a guide plate 11A with a box-shaped cross section provided on the front plate 5A. A guide wall 11 is configured to form a U-shaped exhaust passage 12 when viewed from the side for discharging the cooled air after acting to the front and outside of the aircraft body through the upper part of the engine cover 10.

In addition, 13 in the figure is a cover that covers the front part of the engine 9;
Reference numerals 4 and 15 denote a control section and a grain recovery device, respectively, which are constructed at the rear of the threshing device 5.

In addition, in the above-described embodiment, the engine 9 is arranged with the axis of the power take-off shaft 9A along the direction of movement of the aircraft, but the engine 9 is arranged with the axis of the power take-off shaft 9A along the direction perpendicular to the direction of movement of the aircraft. It can also be applied to combined harvesters.
