Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a combine for harvesting rice or barley or soybean, for example.

[0002]

[Prior art]

 Conventionally, as disclosed in Japanese Utility Model Application Laid-Open No. 60-168328, there is a technique of harvesting cereals by feeding cereal stalks cut with a cereal header to a threshing unit via a feeder house.

[0003]

[Problems to be solved by the invention]

 According to the prior art, in the case of low crops such as soybeans, soil on the surface of the field is easily scattered due to rainfall during growth and easily adheres to culms and fruits, and dried mud during harvesting is fed from the grain header together with the culms and fruits. And fed to the threshing section, the mud that had adhered when the harvested culm was scraped into the feeder house by the platform auger of the grain header became dust, and was operated from above the grain header by wind and other factors. In addition to the problem of being scattered by the workers at the seats, the mud taken into the feeder house adheres to the soybean grain that has been threshed and sorted in the threshing unit, is taken out to the grain tank, and the soybean grain is contaminated with mud powder. is there. Therefore, a dust collector with a dust suction and discharge fan installed inside the dust suction case was mounted on the upper surface of the feeder house to suck and discharge the dust inside the feeder house.However, the air outlet of the dust suction and discharge case was positioned approximately above the center of the platform auger. The dust sucked and discharged by the fan is easily taken in again from the grain header into the feeder house and circulates, and the dust suction efficiency cannot be easily improved. It is necessary to provide a driver's seat at a position to prevent dust blown out from the fan from scattering to the operator, and there is a problem that the overall height of the machine is increased. In addition, since the above-mentioned fan can only be activated and stopped by disengaging the mowing portion clutch, the mowing portion and the fan always operate or stop in conjunction with each other, for example, check the mowing portion. It is necessary to operate the reaping unit also when the fan is operated and when checking the fan, and even when the reaping unit is operated, the discharge of the dust is stopped by stopping the fan, Even if the headland changes direction, there is a problem that the discharge of the dust continues, and there is a problem that it is not easy to improve the dust discharge function and the handling operability.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, a grain header is installed at the front of the threshing section via a feeder house, and a reel for scraping, a cutting blade and a platform auger are provided on the grain header, and a grain tank is provided on the right side of the threshing section. In the combine, a driver's cab provided with a driver's seat is provided in front of the grain tank, and a dust suction / discharge fan for sucking / discharging the internal dust from the feeder house is provided. A dust cover in which a dust fan is installed is attached to the outside of the upper surface or left side surface of the feeder house, and the dust outlet of the dust path formed by the dust cover and the outer surface of the feeder house is opened downward on the left side surface of the feeder house. At the same time, a work discriminator that automatically controls the suction and exhaust fan to be activated by a work start operation and stopped by a work end operation A sensor is provided to discharge dust from the suction / 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 easily reduce the overall height of the aircraft and prevent dust from the driver's seat. It can easily improve the stability of the fuselage and improve the driver's comfort for driving, etc., and close the front and rear at the back of the grain header and the front of the threshing section and uncut grain culm adjacent to the left side of the feeder house. As the dust is discharged downward in the space that blocks the left and right sides, the dust can be released to the cut field without being affected by wind, etc., and the dust sucked and discharged by the suction and discharge fan from the platform auger. In addition to eliminating the problem of being taken back into the feeder house, a dust cover is attached to the outside of the top or left side of the feeder house, and dust is removed from the outside of the feeder house. Since the path is formed, it is easy to simplify the dust cover installation structure, and it is possible to easily improve the dust suction and discharge efficiency by reducing the exhaust air resistance of the suction and exhaust fan, and also to optimize the harvesting situation. Control can be performed to automatically start and stop the suction and discharge fan when necessary, restrict the suction and discharge fan only when necessary, and operate the suction and discharge fan to perform suction and discharge of the feeder house. At times or when dust is improperly discharged, the dust suction and discharge fan can be stopped to stop the suction and discharge of dust, thereby facilitating the improvement of the feeder house dust discharge function and the handling operability.
