Definitions
- the present invention relates to a combine, and more particularly to a technique for a combine in which an exhaust device is piped on the upper part of the fuselage.
- an exhaust device for a combine has been piped to the rear side of the fuselage through the lower part of the engine power unit, and exhaust gas generated by the engine is discharged behind the fuselage.
- the exhaust system includes an exhaust silencer that reduces exhaust noise and a tail pipe that exhausts exhaust gas (see, for example, Patent Document 1).
- an exhaust device such as an exhaust silencer tailpipe is connected to the lower part of the fuselage, mud or the like wound during traveling is likely to be applied to the exhaust device. If mud etc. is applied to the exhaust system, the exhaust silencer may get stuck in the tail pipe and adhere and solidify, or mud may enter the tail pipe. In particular, when the combine is traveling in a wet field, a large amount of mud or the like adheres to the exhaust system, and the intrusion of mud or the like into the exhaust system also increases, so the deterioration of the travel performance of the combine becomes a problem.
- an exhaust device is piped on the upper part of the fuselage.
- an exhaust silencer is provided in an engine room, and the exhaust silencer The connected tail pipe is piped above the machine body, and the rear part of the tail pipe is fixed to the upper part of the threshing part (for example, Patent Document 2).

In addition, it is necessary to install the tailpipe to a certain extent so that the tailpipe is not covered with sawdust or crops. Therefore, if the discharge auger is inadvertently raised and swung, the tail pipe and the discharge auger interfere with each other, and both may be deformed or damaged.
- the exhaust auger can be used by turning the exhaust auger close to the exhaust port of the tail pipe to the position where it hits the exhaust gas. There is also a problem that the surface of the discharge auger tends to become dirty due to easy adhesion to the discharge auger.

- the guard member is arranged in parallel with the discharge direction of the tail pipe in a plan view higher than the downstream end of the tail pipe.
- the surface temperature of the tail pipe is lowered by introducing the exhaust air from the radiator. It also prevents dust accumulation on the muffler pipe. In addition, since it is supported by the threshing section with less vibration, the durability of the tail pipe is improved. In addition, the durability of the tailpile increases, so it is possible to use lightweight materials.
- mud or the like wound during traveling is applied to the exhaust device, and mud or the like is prevented from entering the exhaust device, which is difficult to remove.
- the force S can be used to prevent the exhaust performance of the combine from being lowered due to the mud etc. being trapped in the exhaust system or the intrusion of the mud.

- exhaust is discharged upward, so that mud clogging does not occur in the tail pipe. It also prevents dust from rising from the ground due to exhaust.
- the exhaust gas that does not pollute the discharge auger with scissors or the like does not enter the intake side.
- exhaust is not directly applied to the operator!
- the tip of the tail pipe does not get caught during storage in a garage.
- the exhaust gas does not hit the ceiling or walls during storage, so it does not get dirty.
