BACKGROUND OF THE INVENTION
This invention is intended to be utilized to combine the threshing apparatus, it is related to shall de KokuSo location.
[0002]
[Problems to be solved by the invention]
In the self-elevating combine, the threshed waste that has been transported up to the end of the threshing chamber is sent from the outlet to the rear evacuation chamber. It is scraped out from the scraper into the dust treatment chamber, where it often undergoes a threshing process by rotation of the dust treatment cylinder. However, in such a configuration, the threshing of the threshing that has been scraped from the scraping port to the dust disposal chamber is significantly stagnated at the scraping port part, and the efficiency of the threshing transfer and threshing processing is reduced. Clogging easily occurs at the part.

【The invention's effect】
Drainage threshed by the rotation of the barrel 1 is discharged to the discharge chamber 5, but cereals such as straw scraps are scraped out from the scraper 3 to the dust treatment chamber 9. While being threshed by the rotation, it is discharged into the evacuation chamber 5 and is subjected to the suction dusting action of the suction duster 4. At this time, in the dust removal processing chamber 9, the threshing that is scraped from the scraper 3 is guided by the guide fins 7 having a large transfer guide angle A in the axial direction, so that the delivery speed is high, and therefore the scraper It is possible to reduce the stagnation in the third part, and to quickly perform the threshing scraping process from the threshing chamber 2 to the dust removal processing chamber 9, and the threshing sent from the guide fin 7 is followed by the guide angle. Therefore, the threshing treatment in the dust removal chamber 9 can be sufficiently performed, and the threshing treatment with high efficiency and efficiency can be performed.
Further, in this threshing process, when the transporting cereal is interrupted, the lower edge of the seal plate 34 approaches the surface of the transfer port plate 36 to reduce the gap, thereby preventing dust from being ejected from the cereal transfer port 14. Can do.

DETAILED DESCRIPTION OF THE INVENTION
In the threshing apparatus, a handling cylinder 1 mounted on a threshing frame by a handling cylinder shaft 10 is mounted in a threshing chamber 2. The threshing chamber 2 includes a threshing net 11 stretched on the lower circumferential surface, a threshing cover 12 that can be opened and closed on the upper circumferential surface, and a culm transfer port 14 that guides the cereals transferred by the feed chain 13 along one side. Are disposed on the rear side of the threshing chamber 2 in the axial direction, and a evacuation chamber 5 for discharging the threshed effluent, and a suction dust remover 4 for performing the suction dusting action of the evacuation chamber 5 are disposed. And a dust removal treatment chamber 9 for mounting the dust removal treatment drum 6 with a treatment drum shaft 15 between the scraping port 3 at the rear end of the threshing chamber 2 and the rear portion of the waste removal chamber 5, Below these threshing chamber 2, evacuation chamber 5, and dust disposal chamber 9, a sorting air passage in which a peristaltic sorting shelf 16, a compressed air tang 17, a first catch 18, a second catch 19, etc. are arranged. A sorting device 21 composed of 20 or the like is provided.
[0006]
The threshing chamber 2 is provided with a cereal supply port 22 at the front end in the axial direction, and at the rear end with a sewage port 23 that opens into the sewage chamber 5. The cereals held between 13 and the ridges 24 along the upper side are threshed and conveyed. The rear end of the threshing chamber 2 is provided with a mouthpiece 3 on the back side, and a partition plate 25 having an appropriate height on the surface of the threshing net 11 is provided along the front side edge of the outlet 3.
[0007]
In the dust removal processing chamber 9, a processing net 26 is provided on the upper surface of the sorting device 21, and guide fins 7 and 8 are arranged in a portion constituting the outer wall 28 outside the threshing machine wall. The portion of the guide fin 7 facing the scraper 3 sets a large guide angle A so as to increase the feeding action of the threshing product in the axial direction. Other guide fins 8 on the lower side in the axial direction have a guide angle B smaller than the guide angle A of the guide fin 7. The processed material leaked from the processing net 26 is dropped on the upper surface of the peristaltic sorting shelf 16 below, and the straw scraps and the like conveyed while being threshed to the rear end of the dust disposal chamber 9 are disposed in the waste chamber. 5 is dropped onto the peristaltic sorting shelf 16 below, and the dust is sucked and discharged to the suction dust collector 4.
[0008]
At the rear end of the threshing chamber 2, the threshing between the partition plate 25 and the discharge port 23 is scraped from the scraper 3 toward the dust collection chamber 9 on the back side by the rotation of the barrel 1. The dust removal processing cylinder 6 that rotates in the dust removal processing chamber 9 guides the cereals scraped out from the scraping port 3 to the guide fins 7 and 8 and performs the degranulation processing while transferring them to the discharge port 27 side. Of these, grains and the like are allowed to leak from the treatment net 26, but the remaining large straw waste is discharged from the discharge port 27 to the discharge chamber 5.
[0009]
Such grain removal in the dust removal processing chamber 9 is performed at the portion facing the scraper 3 because the guide fin 7 having a large guide angle A is rapidly fed to the discharge port 27 side. There is little stagnation of threshing, and the threshing of the threshing from the threshing chamber 2 side can be performed smoothly. Further, the grain removal guided inside the dust removal treatment chamber 9 by the guide fins 8 has a small guide angle B, so that the treatment transfer speed becomes slow, and this resistance sufficiently receives the grain removal treatment action. Further, even if the guide angle B of the guide fin 8 is reduced and the processing resistance of cerealing is increased as described above, the amount of straw waste decreases as it is transferred to the discharge port 27 along with the degranulation processing. The processing resistance does not increase excessively.
[0010]
4 and 5, the difference from the above example is that the threshing cover 12 is provided so that it can be opened and closed up and down with the back side of the threshing chamber 2 as a cover shaft 29. In addition, the rod 24 is movable up and down and is springed toward the feed chain 13 by a spring 30. The eaves 24 are connected to each other by pins 31 at fixed lengths, and each pin 31 is supported by an up and down sliding rod 32 and guided to an upright 33 integrated with the threshing cover 12 so as to be slidable up and down. And springs downward with a spring 30. A seal plate 34 made of an elastic material such as a rubber plate or the like is attached to each side surface on the threshing chamber 2 side of each basket 24 located in the grain basket transfer port 14 with screws 35 or the like. Thus, it is made to approach the upper surface of the transfer port plate 36 on the lower surface of the cereal transfer port 14.
[0011]
The sealing plate 34 is formed wider than the upper and lower sides of the ridges 24 so that the lower edge can be pushed up according to the layer thickness of the transferred cereals. Close to the surface of the transfer port plate 36, the culm transfer port 14 is always closed to reduce the gap, and dust is prevented from being ejected from the culm transfer port 14. Further, the front and rear seal plates 34 are superposed over a certain width at the joint portion of each flange 24 so that no gap is generated even when the flange 24 is bent vertically.
[0012]
37 is a resistance plate provided facing the threshing chamber 2 side of the basket 24 and is provided integrally with the threshing cover 12, and an adjustment plate 38 that can be adjusted up and down is provided outside the resistance plate 37. The seal plate 34 moves up and down along with the flange 24 along the outer surface of the adjustment plate 38.
