造を採用できなかつたのである。 To solve the above problem, for example, the feeder house and the platform can be connected in a substantially L-shape in plan view, the protrusion of the platform to one side of the feeder house can be eliminated, and the length of the platform in the width direction can be shortened. When the feeder house and the platform have an L-shaped structure in plan view, the screw blade of the scraping drum provided on the platform is attached to the protruding shaft end of the scraping drum. The structure is equipped with only one screw blade that feeds the grain culm from the feeder house to the feeder house's transport port.
For this reason, a large amount of grain culms gathered together by the screw blades are unilaterally sent to the feeder house side of the raking drum, collide with the side wall of the platform on the feeder house side and become stagnant, and the stagnant portion Since the grain culm is also fed from the side, stagnation of the grain culm is further promoted at the feeder house side end of the raking drum, and the grain culm cannot be smoothly fed into the feeder house by the raking drum. In addition, even if the grain is fed, it will be transported to the threshing device by the conveying device in a state that it is biased to one side in the width direction of the feeder house. There was a problem in that the above-mentioned L-shaped structure in a plan view could not be adopted because of the problem of the occurrence of incorporation.

に阻止できるのである。 Further, since a wrapping prevention portion 12 is provided on the inner surface of the side wall of the platform 5 facing the annular blocking wall, and projects toward the outer periphery of the disc-shaped portion 11,
The wrapping prevention portion 12 and the outer periphery of the disc-shaped portion 11 prevent the grain culm from entering between the end face of the drum body 52a and the inner surface of the side wall of the platform 5, thereby preventing the grain culm from wrapping around the drum shaft. It can definitely be prevented. In this way, the action of the annular blocking wall to prevent grain culms from moving toward the side wall of the platform 5 and the action of sending them to the conveyance port 6a, and the action of preventing the grain culms from wrapping around the drum shaft by the wrapping prevention portion 12 are mutually compatible. In addition, even though the axial length of the raking drum 52 located on the deflection side of the feeder house 6 is shortened and the overall size is reduced, it is possible to reliably prevent grain culms from accumulating or wrapping around. .

Each starting end of 52c is attached to the drum body 5.
The disc-shaped parts 11, 11 may be formed by fan-shaped plates extending in the circumferential direction orthogonal to the axis of the discs 2a and having flat surfaces continuous to the respective spiral parts 52c, 52c. In this case, the spiral portion 52c on the other side overlaps the disk-shaped portion 11 on one side, and the spiral portion 52c on one side overlaps the disk-shaped portion 11 on the other side when viewed from the axial direction. These disc-shaped portions 11, 11 and spiral portions 52c, 52c
This forms an annular blocking wall that prevents grain culm from moving from one axial end of the drum body 52a to the side wall of the platform 5. As a result, each of the disc-shaped parts 1
1, 11 and the spiral portions 52a, 52a can receive the transferred grain culm, and the spiral portions 52c, 52c can feed the grain to the conveyance port 6a.

るのである。(Effects of the Invention) As described above, the present invention includes a reaping device 5 which is provided at the front of the machine body 1 with a platform 51, a cutting blade 54, and a scraping drum 52 with both axial ends facing the inner surface of the side wall of the platform 51. In a general-purpose combine harvester provided through a feeder house 6, the feeder house 6 is deviated to one side in the width direction of the machine body 1, and the feeder house 6 has a transfer port 6.
a is opened on one side of the rear part of the platform 51, and an axial opening is provided on the outer periphery of the drum body 52a of the scraping drum 52, located on the other side in the width direction of the machine body opposite to the deflection direction of the feeder house 6. A screw blade 52b is provided for feeding the reaped grain culm into the transport port 6a from the side across the transport port 6a. A disc-shaped part 11 that protrudes radially outward from the outer peripheral surface of the main body 52a and has a flat surface parallel to a plane orthogonal to the axis of the drum main body 52a, and a starting end of the disc-shaped part 11. A short spiral portion 52c that is continuous and feeds the grain culm from the disc-shaped portion 11 to the transport port 6a of the feeder house 6 is provided, and the shaft of the drum body 52a is formed by the disc-shaped portion 11 and the spiral portion 52c. An annular blocking wall is formed to prevent movement of the grain culm from one end in the direction to the side wall of the platform 5, and an annular blocking wall is formed on the inner surface of the side wall of the platform 5 facing the annular blocking wall on the outer periphery of the disc-shaped portion 11. Wrapping prevention portion 1 protruding toward the front
2, the axial length of the scraping drum 52 located on the deflection side of the feeder house 6 is shortened and the feeder house 6 and the platform 51 are connected in an L-shape in plan view, thereby reducing the size of the combine as a whole. At the same time, it is possible to prevent grain culms from accumulating or becoming entangled near the end of the scraping drum 52 located on the deflection side of the feeder house 6.

確実に阻止できるのである。 That is, when the grain culm is fed into the transport port 6a of the feeder house 6 by the scraping drum 52, a large amount of grain culm transferred to the transport port 6a by the screw blade 52b crosses the transport port 6a and reaches the platform. Although the grain culm is transferred to the side wall of the grain culm, it is blocked by an annular blocking wall consisting of a disk-shaped portion 11 having the flat surface and a short spiral portion 52a continuous with the disk-shaped portion 11. Grain culm is platform 5
Receive it without hitting the side wall of 1 and getting stuck,
In addition, the received grain culm can be smoothly sent to the conveyance port 6a by the feeding action of the spiral portion 52c without being stagnated at the feeder house side end of the drum main body 52a. Furthermore, since a wrapping prevention part 12 that projects toward the outer periphery of the disc-shaped part 11 is provided on the inner surface of the side wall of the platform 5 facing the annular blocking wall, the wrapping prevention part 12 and the disc-shaped part 11 to prevent grain culms from entering between the end surface of the drum body 52a and the inner surface of the side wall of the platform 5,
This makes it possible to reliably prevent winding around the drum shaft. In this way, the annular blocking wall prevents grain culms from moving toward the side wall of the platform 5 and feeds them to the conveying port 6a, and the wrapping prevention portion 1
2 prevents the grain culms from wrapping around the drum shaft, and the axial length of the raking drum 52 located on the deflection side of the feeder house 6 is shortened, and the overall size is reduced. First, it is possible to reliably prevent the grain culms from stagnation or entanglement.
