BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting mechanism for a threshing device mounted on a combine, and more particularly, to a swing sorting case in which a straw rack for receiving a processed material discharged from a dust outlet at the end of a handling room is used. It relates to the sorting mechanism equipped.

[0002]

2. Description of the Related Art Conventionally, as the sorting mechanism, for example, as shown in Japanese Utility Model Application Laid-Open No. 3-126440, a straw rack is provided in a cantilevered manner on the upper part of a swinging sorting case to feed a terminal end of a handling chamber. There is a known configuration in which a lump of processed material discharged from a dust port is rocked and loosened while being separated, so that grains stuck in the processed material can be separated and collected.

[0003]

The straw racks described above have a large number of rack plates arranged in a vertical position and are arranged in parallel on the left and right sides. If the performance is reduced, and if the interval between the rack plates is too small, the recovery efficiency of the grain is reduced when the processing amount is large, and it is difficult to set the interval. The first object of the present invention is to improve the straw rack to provide a loosening function corresponding to the processing amount, and
An object of the present invention is to make it possible to exert a grain collecting function. Further, an object of the second aspect of the present invention is to make it possible to perform switching of the straw rack loosening function and the grain recovery function in synchronization with other sorting adjustments, thereby enabling a better sorting process. Is to do.

[0004]

The feature of the swing sorting mechanism of the threshing apparatus according to the first aspect of the present invention is to swing-sort the processed material.
Equipped with a swing sorting case that is swing driven.
Processed material discharged from the dust outlet at the end of the handling room in the sorting case
And a straw rack for receiving the straw
-Provide a sieving wire between each rack plate in the rack.
The sieving wire of each rack to the swing sorting case.
The height of the upper edge of the plate relative to the corrugated projections is adjustable .

[0005] A characteristic feature of the second aspect of the present invention is that a grain pan for receiving the processed material leaked from the receiving net of the handling room and a straw rack for receiving the processed material discharged from the dust port at the end of the handling room. In the swing sorting mechanism of the threshing apparatus, which is provided with an opening-adjustable chaff sheave for coarsely sorting while transporting the processed material transported by the Glen pan toward the straw rack, between the rack plates in the straw rack In addition, the sieve wire is provided in a cantilever shape facing backwards and swingable up and down with the front end as a fulcrum, and when the opening degree of the chaff sheave is increased, the sieve line is lowered, and when the opening degree of the chaff sheave is reduced, the sieve line is raised. As a result, the screen line and the opening adjustment mechanism of the chaff sheave are linked to each other.

[0006]

According to the structure of the first aspect of the invention, when the amount of the processed material is large, the sieving line is lowered to be separated from the upper edge of the rack plate, thereby forming the upper edge of the rack plate along the front-rear direction. The projecting amount of the corrugated projections with respect to the sieve line is set to be large, and the feeding action of the rack plate to the processing object is effectively exerted, and the processing object mainly rides on the rack plate. As a result, the processing object is supplied to the rack plates arranged side by side at a large interval and receives a high unraveling action. On this occasion,
Although the sorting performance is slightly reduced due to the increased dropping property of the processed material, the stuck kernels and the second product are efficiently dropped and collected. In addition, when the amount of the processed material is small, the sieve line is raised and positioned between the rack plates, so that the amount of protrusion of the wavy projections formed along the front-rear direction on the upper edge of the rack plate with respect to the sieve line is reduced. To a certain extent to reduce the effect of the rack plate on the workpiece
By facilitating the treatment on not only the straw rack but also the sieve line, the substantial leakage interval in the straw rack is reduced, and the sorting performance is enhanced.

Further, according to the configuration of the second aspect of the invention, the opening degree of the chaff sheave is increased when the processing amount is large, and the opening degree of the chaff sheave is reduced when the processing amount is small. By linking the screens,
Since it is synchronized with the above-described posture adjustment of the vertical movement of the sieve line, it is not necessary to separately adjust the opening degree of the chaff sheave and the vertical position of the sieve line with respect to the straw rack.

[0008]

As described above, according to the first aspect of the present invention, the relative height of the screen line relative to the upper edge of the rack plate is changed in accordance with the amount of material to be processed and the position of the screen line is used as a reference. In this case, the amount of protrusion of the corrugated projections of the rack plate can be changed, whereby the feeding function, the loosening function, and the kernel collecting function corresponding to the processing amount can be exhibited in the straw rack. It became so.

Further, according to the second aspect of the present invention, the adjustment of the vertical movement of the sieve line for exhibiting the above-mentioned effect is linked to other adjustments for selection, so that the adjustment can be simplified and more suitable selection can be achieved. Processing can now be performed.

In the drawing, reference numeral 1 denotes a handling room supporting the handling cylinder 2; 3, a receiving net provided along the lower portion of the handling room 1, 4; a feed chain, 5: a swing sorting case, 6: a karamin for wind sorting, Reference numeral 7 denotes a dust exhaust fan, 8 denotes a first recovery unit, 9 denotes a second recovery unit, and 10 denotes a second reduction device that supplies the second product to the front of the swinging and sorting case 5. The swing sorting case 5 includes a grain pan 11 for receiving the processed material leaked from the receiving net 2, a chaff sieve 12 for rough sorting, and a grain sieve 1 for fine sorting.
3. A first straw rack 15 for receiving the processed material discharged from the dust outlet 14 at the end of the handling chamber 1, a chaff sheave 16 below the first straw rack 15, and a second straw rack 17 are provided. As shown in FIG. 1, the opening degree of the rough-selection chaff sheave 12 is automatically adjusted by an opening degree adjusting mechanism A. The opening adjustment mechanism A measures the amount of retreat of the holding rail 18 with respect to the feed chain 4 by the sensor 19 to detect the amount of grain culm supplied, and based on the detection result, the selection control mechanism 20 and the drive circuit 2
