Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention scrapes culm culms by a scraping carrier to merge them, and conveys the merged culms to the threshing device in an inclined posture by a handling depth carrier capable of adjusting the handling depth. The present invention relates to a grain culm transporting device in a combine harvester.

[0002]

2. Description of the Related Art Conventionally, a stock carrier, a stem carrier, and an ear which are scraped by a cutting blade and scraped with a star wheel and whose rear end is tilted upward at substantially the same angle in a side view. Left and right scraping conveyors composed of side conveyors are merged and conveyed, and the merged grain culms are conveyed in depth, which consists of the ear side conveyor with a tine and the stock yuan conveyor with a holding rail. It is configured to be passed on to the body, and the grain side of the grain culm is slanted toward the center of the machine while adjusting the handling depth to be conveyed and fed to the rear threshing section. In some cases, the transport section was in a substantially horizontal state, and in other cases, the slants were in a substantially orthogonal state.

[0003]

However, when the harvested grain culm has been conveyed by the scraping carrier especially when the culm is long culm, the tip portion of the scraping carrier protruding above the spike-side carrier drops. At this time, when the ear-side transport section of the handling depth transporter is provided so as to be inclined so as to be substantially orthogonal to the grain culms that are transported in an inclined state, the uncut area side is high when viewed from the front. Since it is inclined, it does not align with the end of the ear-side carrier on the uncut side of the scraping carrier, and it takes over the hanging part of the grain culm. The uncertainties in the succession of rice will cause troubles such as disturbance of transportation to the threshing section and defective threshing due to the disturbance during the succession. In addition, if the ear-side carrier of the handling depth carrier is not substantially orthogonal to the tilted grain culm, there is a problem in that the transportation of the grain side of the grain culm becomes more unstable.

It is characterized in that they are brought close to the swing lower limit position of the start end portion of the bristle side transport portion 31 in a side view and a plan view, respectively.

[0005]

By the above mechanism, the end of the bristle carrier 17a is brought closer to the upper limit position of the starting end of the handling depth carrier 16 or the ends of the stem carriers 18a, 18b are brought closer to the lower limit position. In both cases of culm and short culm, the harvested grain culm is surely and smoothly inherited from the scraping carrier 14 to the handling depth carrier 16, so that the mess of transport to the threshing unit 7 due to turbulence at the time of inheritance or defective threshing is caused When the trouble of No. 1 is solved and the spike-side transport section 31 of the handling depth transporter 16 is tilted so as to be substantially orthogonal to the slanted culm, the culm-side transport of the culm is more reliably adjusted. There is an effect that is.
