Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides an auger having spiral blades for gathering grain culms from a reaping device from both left and right side ends to an intermediate location, and cutting a grain culm from the auger with an auger. The present invention relates to a combine harvested culm conveyor device provided with a conveyor for conveying and supplying the thresher along a guide bottom surface of a conveyor tube from a gate.

[0002]

2. Description of the Related Art A conventionally known Japanese Utility Model Laid-Open No. Sho 58-4128 is provided with an auger having spiral blades for gathering grain culms from a reaping device from both left and right end portions to an intermediate position.
In a combine provided with a conveyer for feeding cut grain culms from moths from an agate table to a thresher along the guide bottom of a conveyor tube, depending on the auger, it is hung from the machine side above the auger. A configuration is shown in which a discharge prevention rod is provided that abuts a rotating grain culm and drops it on the conveyor side.

[0003]

According to such a conventional technique, even if the grain culm to be supplied to the threshing device is returned to the front side from the return route side portion of the conveyor due to, for example, adhering to the conveyer, the returned grain culm is returned. Will be discharged above the auger, so that the lower end of the discharge prevention rod and the outer peripheral surface of the auger are entangled and entangled, and wrapping around the auger easily occurs, and the There was a problem that it was difficult to take over smoothly.

An object of the present invention is to eliminate such a problem. To achieve this purpose, the following technical measures were taken.

[0005]

That is, according to the present invention, an auger 8 having a spiral blade 16 for gathering grain culms from a reaping device 7 from both left and right ends to an intermediate position is provided, and the auger 8 is also provided. In a combine provided with a conveyor 11 for feeding and cutting the harvested culm from the ogable 14 along the guide bottom surface 13 of the conveyor cylinder 10 to the threshing device 3,
Take-over port 1 of the auger table 14 and the conveyor tube 10
A guide cover 19 is provided above 5 to prevent the conveyed product from the return path side portion (b) of the conveyor 11 from being discharged above the auger 8. On the other hand, the starting end portion of the conveyor 11 is arranged so that the rotation locus of the conveying lug of the conveyor 11 intervenes in the outer peripheral rotation range of the spiral blade 16 of the auger 8 in a side view.

[0006]

During the harvesting work, the grain culms harvested by the harvesting device 7 are laterally fed by the spiral blade 16 of the auger 8 and gathered together at the take-over port 15. Then, the gathered grain culms are taken over from the take-over port 15 to the starting end portion of the conveyor 11, but at this time, they are reliably taken in by the transport lug 12 of the conveyor 11 and lifted along the guide bottom surface 13 of the conveyor tube 10. The entire amount is conveyed to the threshing device 3 and is conveyed. Also,
Even if there is a culm which is returned to the front from the return path side portion on the upper part of the conveyor, it is received by the guide cover 19, and the guide cover 19 guides it to flow down between the auger and the starting end of the conveyor. It is picked up by a transport lug and lifted and transported together with the grain culm.

[0007]

Therefore, according to the present invention, the guide cover is provided.
Since it is received and is guided to fall between the auger and the starting end of the conveyor, it is possible to prevent the return grain stem from the return path side of the conveyor from being wound around the auger. Moreover, since the tip rotation locus of the conveyor lug of the conveyor intervenes on the axial center side of the outer gyro of the auger spiral blade, the return from the grain culm and the conveyor that have been pushed up to the takeover port of the conveyor cylinder. It is possible to reliably take in the grain culm by the conveying lug and efficiently convey and supply it to the rear threshing device.
