BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for harvesting, for example, rice, barley or soybean.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Application Laid-Open No. Sho 60-168328, there is a technique for harvesting cereals by supplying cereal stalks cut by a cereal header to a threshing unit via a feeder house.

[0003]

According to the prior art, in the case of low crops such as soybeans, the soil on the surface of the field is scattered due to rainfall during growth and easily adheres to the culm and the fruits. And the berries are taken into the feeder house from the cereal header and fed to the threshing unit, so that mud that has adhered when the cut culms are scraped into the feeder house by the platform auger of the cereal header becomes dust, There is a problem that the operator in the driver's seat is scattered from above the grain header due to such factors, and the mud taken into the feeder house adheres to the soybean grains that are threshed and sorted in the threshing unit, is taken out to the grain tank, and is removed. However, there is a problem that it is stained by mud powder. Therefore, a dust extractor with a dust suction and exhaust fan installed inside the dust suction and exhaust case is mounted on the top of the feeder house,
Although the dust inside the feeder house was sucked and discharged, the dust outlet sucked and discharged by the fan was taken in again from the grain header to the feeder house because the outlet of the dust suction and discharge case was opened almost upward of the center of the platform auger. It is rare to easily circulate, it is not possible to easily improve the suction and exhaust efficiency, and it is necessary to provide a driver's seat at a high position away from the top of the grain header to prevent dust blown out from the fan from scattering to the operator. There is a problem that there is a problem that the overall height of the aircraft is high. Also, since the fan can only be activated and stopped by engaging and disengaging the mowing section clutch, the mowing section and the fan always operate or stop in conjunction with each other, for example, when inspecting the mowing section. It is necessary to operate the reaping unit also when the fan is operated and the fan is inspected. Further, even when the reaping unit is operated, the discharge of the dust is stopped by stopping the fan, However, there is a problem that the discharge of dust is continued even when the direction is changed, and it is not easy to improve the dust discharge function and the handling operability.

[0004]

According to the present invention, a grain header is mounted on a front side of a threshing unit via a feeder house so as to be able to move up and down, and a scraping reel, a cutting blade and a platform auger are provided on the grain header. A grain tank is provided on the right side of the threshing unit, a driver's cab with a driver's seat is provided in front of the grain tank, and a dust suction fan that sucks and discharges internal dust from the feeder house is installed. A stand is disposed, and a dust cover for installing the suction / discharge dust fan is attached to the outside of the upper surface or the left side surface of the feeder house, and a dust outlet of a dust air passage formed by the dust cover and the outer surface of the feeder house is provided. The feeder house is opened downward on the left side of the feeder house, and the dust suction and discharge fan is activated by the operation start operation and stopped by the operation end operation. Is provided to automatically discharge the dust from the dust suction and discharge fan downward on the left side of the feeder house.Therefore, a driver's cab is provided at a low position on the right side of the feeder house to reduce the overall height of the aircraft and operate it. The seat can be easily dustproofed, and the stability of the fuselage can be easily improved, and the driving comfort of the operator can be easily improved.The front and rear sides of the grain header and the threshing section are closed and the feeder house is on the left side. Since the dust is discharged downward in the space that blocks the left and right with the adjacent uncut culm, the dust can be discharged to the cut field without being affected by wind, etc., and the dust sucked and discharged by the dust suction and discharge fan Can be removed from the platform auger into the feeder house again, and a dust cover is attached to the outside of the upper surface or the left side surface of the feeder house. Since the exhaust air path is formed with the outer surface, it is easy to simplify the dust cover installation structure, and it is possible to easily improve the efficiency of intake and exhaust by reducing the exhaust resistance of the intake and exhaust fans. In addition, it is possible to perform control to automatically start and stop the suction and discharge fan according to the appropriate judgment of the harvest work situation, and to restrict and operate the suction and discharge fan only when necessary to perform suction and discharge of the feeder house. In addition, when unnecessary or when the dust is not properly discharged, the suction and discharge fan can be stopped to stop the suction and discharge, thereby improving the feeder house dust discharge function and the handling operability easily. .
