The outer circumferential surface of the Moeki auger 8 is provided with spiral blades 16 and 16 for conveying grains and grains toward the transfer port 15. That is, the spiral blades 16, 16 are not formed in the auger 8 in the front part of the transfer port 15, and this part is provided with an orca fin car 17 for feeding the grain culms and grains into the conveyor cylinder IO. The finger finger 17 is configured to gradually protrude when the rotation of the orca 8 reaches the downward rotation side, and gradually retract when the rotation reaches the upward rotation side.

A rear wall l8 of the auger table 14 is provided with a cover/<-19 of the auger 8. The guide cover 19 prevents the grain culms and grains conveyed by the spiral Qt6 of the auger 8 from rotating together with the auger 8 and scattering them to the front bush j. Form long. The cross-sectional shape of the guide cover 19 has an upper surface and a lower surface 2.
It has a triangular shape, with its tip facing above the orca 8.

The lower part 21 of the guide cover 19 above the transfer port 15 is cut out to facilitate the feeding of the grain culms and grains to the conveyor cylinder 10 by the first finger 17 of the auger 8.

Then, the upper end of the elastic sliding contact body η is fixed to the seventh surface 20 of the guide cover 19 above the transfer port 15 (if the guide cover 19 is not provided, it is fixed to the rear wall of the cover 4). .

The elastic sliding contact body is made of rubber, synthetic resin, etc. and is formed into a single plate shape, and its left and right width is formed to be approximately the same as the transfer port 15.

The lower end of the elastic sliding contact body is made to protrude forward at an inclination that is substantially the same as the upper surface of the force-id cover 19, and is attached to the outer circumferential surface of the auger 8 on the rear side of the vertical line Y-Y passing through the center of the auger 8. Make sliding contact.

An auger finger 17 is provided on the outer peripheral surface of the auger 8 in front of the transfer port 15, and the auger finger 17 gradually protrudes as the auger 8 reaches the downward rotation side and gradually retracts as the rotation reaches the upward side. 17 hooks the grain culm on the rotating downward side of the auger 8 and sends it to the rear, gradually retracts it in front of the transfer port 15, transfers the grain culm to the conveying body 12 of the conveying device 11 of the conveyor tube 10, and transfers the grain culm to the conveyor tube 10. The conveying device 11 supplies candy to the threshing device 3 for threshing.

In this case, the auger finger 17 gradually retracts in front of the transfer port 15 and transfers the grain culm to the transfer member of the transfer device 11 of the conveyor tube 10, but the auger finger 17 causes the grain culm to be over-supplied toward the transfer port 15. The finished grain culm is auger 8
In addition, the short culm cut grains rotate together with the auger 8 and are blown forward, and the long grain culms wrap around the outer circumferential surface of the auger 8 and are smoothly transferred to the conveyor 1l of the conveyor pipework 0. There are some things that I can't do.

In the present invention, the guide cover 19 above the transfer port 15
The upper end of the elastic sliding body η, which is made of rubber, synthetic resin, etc. and has a plate shape, is attached to the upper surface.The lower end of the elastic sliding body η is
Vertical line Y-Y passing through the center of the O force 8 in side view
Since it is in sliding contact with the outer peripheral surface of the auger 8 on the rear side, all the grain culms and grains that try to rotate together with the auger 8 come into contact with the lower surface of the elastic sliding contact body η, and the front side of the transfer port 15 to fall.

Further, the grains wrapped around the outer peripheral surface of the auger 8 are also scraped off by the lower end of the elastic sliding member, and fall to the front side of the transfer port 15.

Therefore, all of the grain culms and grains that have fallen to the front side of the M-drawing port 15 are supplied to the threshing device 3 by the conveying body 2 of the conveying device 1l.

Moreover, since the grain culm wrapped around the outer peripheral surface of the auger 8 is also scraped off by the tip of the elastic sliding member η, the grain culm is prevented from wrapping around the outer peripheral surface of the auger 8 and the auger fingers 17.

(Effects) The conventionally known Japanese Patent Application Laid-Open No. 58-4128 discloses a reaping section having a threshing device at the upper position of a machine body having a traveling device, and an auger table equipped with a cutting blade and an auger in front of the machine body. In a combine in which a conveyor tube extending from the auger table to the threshing device is provided between the reaping section and the threshing device, above the transfer port between the auger table and the conveyor tube, the upper end is connected to the transfer port. The document describes a reaping section of a combine that is provided with a sliding body that is fixed at an upper fixed position and whose lower end slides in sliding contact with the outer circumferential surface on the front side of the vertical line passing through the center of the auger. Because of the structure in which the sliding body whose lower end slides in sliding contact with the outer peripheral surface on the front side of the vertical line passing through the center of the Jingji auger, the grain culm that rotates with the auger can slide into contact with the outer peripheral surface on the front side. There was a problem in that the lower end of the auger got caught in the contact area with the outer circumferential surface of the auger.

However, the present invention provides a traveling frame 1 having a traveling device 2.
A threshing device 3 is installed in the upper position of the mower, and a reaping section 4 having an auger table 14 equipped with a cutting blade 7 and a cutter 8 is installed in front of the traveling frame 1 between the reaping section 4 and the threshing device N3. In a combine in which a conveyor tube 10 extending from the auger table 14 to the threshing device 3 is provided, the upper end is fixed at a position above the transfer port 15 above the transfer port 15 between the auger table 14 and the conveyor tube ]O. The lower end is used as the reaping part of the combine, which is provided with an elastic sliding body 22 that slides on the outer peripheral surface on the rear side of the vertical line Y-Y passing through the center of the auger 8, and the lower end of the sliding body By simply changing the contact position with the outer circumferential surface of the auger 8, it is possible to prevent the tip of the Wi contacting body and the contact portion with the outer circumferential surface of the auger from getting entangled, which is the case in the known example, so it is inexpensive and easy to implement. It has the effect of being easy.
