BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for threshing by feeding the whole amount of cereal stalks cut in a cutting section to a threshing section.

[0002]

Conventionally, a mowing header is mounted on the front side of the threshing section via a feeder house so as to be able to move up and down, and the culm stalked by an uncut culm raking reel is cut by a cutting blade and raked. There is a technique for performing a harvesting operation of feeding a feeder house from a garage auger. However, by driving the cutting blade and the scraping auger on the same shaft, there is a problem that workability such as maintenance and repair of the scraping auger driving chain cannot be easily improved. Further, it is necessary to protrude and support the support shaft of the scraping auger outside the left and right side plates of the mowing header, thereby performing a troublesome operation of detaching the support shaft or the side plate and detaching the scraping auger. Further, since the left and right side plates on the side of the scraping auger are fastened and fixed to the cutting frame by bolts, assembly time is required, the number of parts is large, the weight is heavy, and the manufacturing cost is high. In addition, by attaching a spiral and a finger to the drum that forms the scraping auger, and throwing out the grain culm brought to the center by the spiral to the feeder house with the finger, the culm is caught on the finger part and the culm is wound around the drum. is there. Further, by providing the unarmed culm scraping reel on the lift arm so as to be adjustable in the front-rear position, the lift arm easily swings right and left, and it is necessary to increase the strength of the lift arm fulcrum. Further, by disposing the weeding plate at the front side of the uncut culm raking reel, there is a problem that the posture of the grain culm caused by the reel is disturbed in the course of transportation and easily winds around the raking auger.
In addition, by providing a position adjusting cylinder for moving the uncut grain culm raking reel back and forth in the center of the cutting unit left and right width, the step of getting on and off the cab provided behind the center of the cutting unit and the mounting position of the cylinder are mutually restricted, There is a problem that the total length of the machine body is increased by preventing interference between the step and the cylinder. Also, by extending the hydraulic hose of the reel elevating cylinder on the upper surface of the upper frame of the mowing part, the hydraulic hose is easily damaged by collisions and the like, and a hydraulic hose fixing part is required, and the design feeling is poor and the weight is large. There is a problem such as becoming. In addition, by caulking and fixing the cutting blade, knife bar and knife head with rivets, it is necessary to replace the cutting blade when the knife head is broken. In addition, by forming the inclination angles of the front and rear bottom portions of the feeder house to be the same, the front portion of the feeder house is steeply inclined, so that the inheritance conveyance is easily deteriorated, and the rear portion of the feeder house is gently inclined, so that the front and rear length is reduced.

Further, the front and rear lengths of the left and right weeding plates on the sides of the uncut culm raking reel are formed to be substantially equal to the front and rear width of the reel.
Since the weeded culm is passed on to the scraping auger in a state where it is raised by the reel and weeding board, the culm can be transported smoothly without disturbing the posture of the culm. It can easily prevent the stalk auger from wrapping around the culm.

In addition, a position adjusting cylinder for moving the uncut culm scraping reel back and forth is disposed at an end of the reaping portion side.
Since the steps of the cab behind the reaping unit and the cylinder are mounted without being restricted to each other, the hulling unit and the cab can be brought closer to each other to reduce the overall length of the fuselage, and the strength of the cylinder mounting portion can be reduced and simplified. It can be configured as follows.

In addition, a hydraulic hose of a reel elevating cylinder is inserted into the pipe-shaped upper frame of the mowing part.
The upper frame protects the hydraulic hose to prevent damage to the hydraulic hose, and eliminates the need for a clamp to fix the hydraulic hose, reducing the number of parts, improving appearance, reducing weight, and reducing manufacturing costs. It is possible to achieve.

Further, the knife head is detachably bolted and fixed to the cutting blade and the knife bar, so that only the knife head can be replaced as a single item, the repair workability can be improved, and the repair cost can be reduced. is there.

Also, the front bottom plate and the rear bottom plate of the feeder house are made to have different inclination angles, and the front bottom plate of the feeder house is formed to have a gentle inclination so that the grain stalk can be smoothly received and the feeder can be fed smoothly. The rear bottom plate of the house can be formed with a steep slope to shorten the front-back length of the feeder house,
The platform bottom surface of the mowing header and the bottom surface of the front part of the feeder house can be formed on the same plane.
