Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing and dust-treating apparatus for use in a combine threshing apparatus.
The scraping process at the threshing material discharge port at the end of the threshing room is promptly performed.

[0002]

In the self-extracting combine, the threshed culm conveyed to the end of the threshing chamber is sent out from the culm opening to the rear culm chamber. Threshing material that is threshed by rotation is scraped out of the scraping port into a dust treatment chamber, where it is often subjected to threshing by rotation of a dust treatment cylinder. However, in such a configuration, the thresh scraped out from the scraper to the dust treatment chamber is significantly stagnated at the scraper portion, which reduces the efficiency of the transfer of thresh and threshing processing, etc. Clogging in the part is also likely to occur.

[0003]

According to the present invention, a threshing scrap port 3 at the end of a threshing chamber 2 on which a handling cylinder 1 is mounted, and a suction / discharge unit 4 of a suction / dust discharger 4 while feeding threshed culms. Between the culm chamber 5 for receiving dust, a dust treatment chamber 6 is mounted on which a dust treatment cylinder 6 is mounted, and guide fins 7 and 8 for transferring and guiding the treated material in the axial direction are arranged on the inner periphery. The guide angle A of the guide fin 7 in the portion of the dust treatment chamber 9 facing the scraper 3 is
The threshing and dust-treating device is configured to be set to be larger than the guide angle B of the rear guide fin 8.

[0004]

The culms that are threshed by the rotation of the handling drum 1 are discharged to the culm chamber 5, but thresh such as straw chips are scraped by the scraper 3.
The dust is scraped out of the dust collecting chamber 9 and discharged to the culm chamber 5 while being threshed by the rotation of the dust processing drum 6, and subjected to the suction / dust action of the suction / dust generator 4. At this time, in the dust treatment chamber 9, threshing material scraped out from the scraper 3 is
Since the guide fins 7 are guided by the guide fins 7 having a large transfer guide angle A in the axial direction, the delivery speed is high, and the
The stagnation in the section is reduced, and the threshing chamber 2 is moved to the dust treatment chamber 9
The threshing material sent from the guide fins 7 is subjected to threshing resistance by the guide fins 8 having a small guide angle. Threshing in the dust treatment chamber 9 is sufficiently performed, and threshing with high efficiency and efficiency can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the threshing apparatus, a handling drum 1 which is mounted on a threshing frame with a handling drum shaft 10 is mounted in a threshing chamber 2. The threshing room 2 has a threshing net 11 stretched on a lower half peripheral surface, a threshing cover 12 openable and closable on an upper peripheral surface, and a cereal culm transfer port 14 for guiding cereal culm transported by a feed chain 13 along one side. At the rear side of the threshing chamber 2 in the axial direction, a culm chamber 5 for discharging the threshed culms, and a suction duster 4 for performing a suction / dust action of the culm chamber 5 are arranged. And, between the scraper 3 at the rear end of the threshing chamber 2 and the rear part of the culm chamber 5, there is a dust treatment chamber 9 in which the dust treatment cylinder 6 is mounted on the treatment cylinder shaft 15, Below these threshing room 2, culm room 5, and dust treatment room 9,
There is provided a sorting device 21 including a swing sorting shelf 16, a pressurized air tray 17, a sorting wind path 20 in which the first gutter 18, the second gutter 19 and the like are arranged.

[0006] At the front end in the axial direction of the threshing chamber 2, there is provided a grain culm supply port 22, and at the rear end there is provided a culm opening 23 opening to the culm chamber 5, and below the transfer port 14. The grain stalk held between the feed chain 13 along the upper side and the clamping rod 24 along the upper side is threshed and conveyed. At the rear end of the threshing room 2, a scraper 3 is provided at the back side, and along the front edge of the scraper 3, an intermediate partition plate 25 is provided on the threshing net 11 at an appropriate height.

In the dust treatment chamber 9, a treatment net 26 is provided on the upper surface of the sorting device 21, and guide fins 7, 8 are arranged in a portion constituting an outer wall 28 outside the wall of the threshing machine. The guide fins 7 in the portion facing the raking port 3 are set to have a large guide angle A so as to increase the feeding action in the axial direction of the threshing product. The 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 fins 7. The processed material leaking from the processing net 26 is dropped on the upper surface of the swinging sorting shelf 16 below, and the straw debris and the like conveyed while being threshed to the rear end of the dust processing chamber 9 are removed from the culling chamber. 5 is the lower swing sorting shelf 16
The dust is dropped upward, and the dust is sucked and discharged to the suction / dust generator 4.

At the rear end of the threshing chamber 2, threshing between the partitioning plate 25 and the culm opening 23 is raked out of the scraper 3 by the rotation of the handling cylinder 1 to the back of the threshing chamber 9. It is. The threshing particles scraped out of the scraping port 3 are guided by the guide fins 7 and 8 and transported to the discharge port 27 side by the dust processing cylinder 6 which rotates in the dust processing chamber 9 to perform the threshing process. Of these, grains and the like are allowed to leak from the treatment net 26, but the remaining large straw waste is discharged to the culm chamber 5 from the discharge port 27.

The threshing material in the dust treatment chamber 9 is fed at a high speed to the discharge port 27 by the guide fins 7 having a large guide angle A in a portion facing the scraping port 3. There is little stagnation of thresh at the scraper 3, and the threshing from the threshing chamber 2 can be smoothly scraped. Further, the guide fins 8
Since the threshing material guided by the method has a small guide angle B, the processing transfer speed becomes slow, and the threshing action is sufficiently received by this resistance. Even if the guide angle B of the guide fins 8 is reduced to increase the processing resistance of the thresh as described above, the amount of straw waste decreases as the straw is transferred to the discharge port 27 during the threshing process. However, the processing resistance does not increase excessively.

4 and 5 are different from the above example in that:
The threshing cover 12 covers the back side of the threshing chamber 2 with a cover shaft 29.
The threshing cover 1
Along the grain stalk transfer port 14, the clamping rod 24 is movable up and down and is repelled toward the feed chain 13 by a spring 30. The pinching rods 24 are connected by pins 31 at regular intervals, and each pin 31 is connected to a vertical sliding rod 32.
, And is guided slidably up and down by a clamping table 33 integrated with the threshing cover 12, and is resiliently moved downward by a spring 30. A sealing plate 34 made of an elastic material such as a rubber plate is attached to the side of the threshing chamber 2 side of each of the nipping rods 24 located at the grain culm transfer port 14 with a screw 35 or the like. Thus, it is brought close to the upper surface of the transfer port plate 36 on the lower surface of the cereal stem transfer port 14.

The seal plate 34 is formed so as to be wider in the vertical and horizontal directions than the clamping rods 24 so that the lower edge is pushed up according to the thickness of the transferred cereal culm, so that the transfer of the cereal culm is cut off. In this case, it approaches the surface of the transfer port plate 36 and always closes the cereal culm transfer port 14 to reduce the gap, thereby preventing dust from being ejected from the cereal culm transfer port 14. Further, the front and rear seal plates 34 are overlapped over a fixed width at the joint portion of each clamping rod 24 so that no gap is generated even when the clamping rod 24 swings up and down.

Reference numeral 37 denotes a resistance plate provided opposite to the threshing chamber 2 of the clamping rod 24, and is provided integrally with the threshing cover 12, and an adjustable plate 38 which can be adjusted up and down is provided outside the resistance plate 37.
The seal plate 34 moves up and down along with the clamping rod 24 along the outer surface of the adjustment plate 38.
