た。2. Description of the Related Art Conventionally, a thresher mounted on a combine harvester or a harvester causes the grains threshed by the handling barrel to leak from the net.
This is sorted in the sorting section and sorted into the first and second products, and the first product is transported horizontally and the first horizontal helix and the grain lifting device with the lifting helix are installed in the grain tank. On the other hand, while the second conveyor is lifted and conveyed, the second conveyor is reduced and conveyed to the sorting section by the second transverse spiral that conveys in the horizontal direction and the reduction conveyor device that incorporates the second vertical spiral that conveys the lift. In general, the structure is such that the second product is sorted again.

乾燥機詰り等の不都合が生じるという欠点があった。However, the second cuts sorted as described above include panicles, branch shoots, etc., which are contained in the second cut. Since the grains are burdened with re-sorting after reducing and transporting, the overall threshing efficiency deteriorates, and if the grains after reducing threshing include spike cuttings and twigs, the final sorting accuracy will be reduced. When the grains are reduced and the grains after threshing are put in a drier, there is a disadvantage that the branch stems separated by the drying cause inconveniences such as clogging of the drier.

As disclosed in Japanese Patent Publication No. 43134, there is known a method in which branch stem particles, panicle cutting grains and the like contained in the second product are made into a single grain and reduced and conveyed to a sorting section. It has a processing part with a processing tooth for slicing the cutting grain etc. at the end of the No. 2 horizontal spiral, and has a mechanism for slicing the No. 2 grain during the reduction conveyance of the No. 2 grain. is there. However, in this case, the processing section is relatively large and the mechanism is complicated, which requires a relatively large space for mounting and has a drawback that the cost is significantly increased.

On the (upper surface), a plurality of processing plates 32 each having a substantially L-shaped cross section, which is a processing member protruding in the direction of the rotating shaft 22a and extending in the radial direction of the spiral, are provided at predetermined intervals in the spiral direction. The processing plate 32 is fixed to the spiral band plate member 22b and the rotary shaft 22a. With the above structure, the processing plate 32 pushes out the second object being conveyed to the inner peripheral surface side of the conveying cylinder 21 when the second vertical spiral 22 rotates and the second object is lifted and conveyed.

The lid portion 34 is attached to the fixing portion 33 by fixing both flanges 36 and 37 with 41. That is, the lid portion 34 is configured by the cover portion 35, which is attached to the fixing portion 33 and forms a part of a cylinder that covers the outer periphery of the second vertical spiral 22 together with the fixing portion 33, and the flange 37.

By removing the fixing member 41 from the side of the transport cylinder 21 while holding, the fixing portion 33 and the lid portion 34 can be easily attached and detached. The fixing portion 33 has a structure in which the lid portion 34 is attached and detached from the right side, and the transfer cylinder 21 (fixing portion 3
Since 3) is provided on the right side of the sorting section 5 as described above, there is no obstacle on the right side of the fixing section 33, and the lid section 34 is provided.
Can be attached and detached more easily.

Are provided along the circumferential direction on the inner peripheral surface of at a predetermined interval in the vertical direction. At this time, the processing protrusion 42 is covered by the cover 35.
Of the second vertical spiral 22 is attached to a portion facing the processing plate 32 when the lid 34 is attached to the fixing portion 33, and is substantially opposite to the outer periphery of the conveying surface (upper surface of the spiral band plate material 22b) of the second vertical spiral 22. . The processing projection 42 may have a cross-sectional shape such as a circle, an ellipse, or a polygon.

By attaching the lid portion 34 to the fixing portion 33 as described above, the processing protrusion 42, which is inclined at an advance angle in the conveying direction of the second product, is provided on a part of the inner peripheral surface of the conveying cylinder 21 so as to project therefrom.

As described above, in the portion where the processing protrusion 42 is provided, the processing protrusion 42 narrows the interval t on the lid portion 34 side with respect to the interval T on the fixed portion 33 side. That is, the interval for the second product to pass upward when the second product is lifted and conveyed is narrower on the lid portion 34 side than other portions.

As a result, the second grains are rubbed or rubbed against each other, so that the panicle grains and the branch shoot grains are made into a single grain, and the second grain that has become a single grain is reduced and conveyed to the sorting unit 5 to the swing sorting body 9. Be reduced.

Not only does the branching grain become a single grain as much as possible, but the processing plate 32 pushes the second object outward with the rotational drive of the second vertical spiral 22 to bring it into contact with the inner peripheral surface side of the transport cylinder 21. By utilizing the friction generated based on the contact, it is possible to further promote the slicing of the panicle grains and the branch shoot grains into single grains.

The cutting burden after reduction conveyance is reduced because the cuttings are not mixed, and the threshing efficiency is improved overall, and the single grain ratio in the grain after threshing is higher than before, and after threshing, Even when the grains are subjected to a processing device such as a drier (not shown), the inconvenience such as clogging of the drier due to branch stems or the like does not occur.

Smooth lifting transportation is performed without obstruction more than necessary. Since the grain singulation mechanism of the present invention can be configured by attaching the processing plate 32 and the processing protrusion 42 to the conventional reducing and conveying device 19, no special space for attachment is required, and the parts are The number of points is small, the mechanism is simple, and it is advantageous in terms of cost.

的に脱穀効率が向上する。According to the present invention configured as described above, when the grains threshed by the handling cylinder are conveyed, the gap between the conveying spiral and the conveying cylinder in the conveying device is treated by the conveying cylinder. The area where the projection is provided is narrower than other areas. For this reason, for example, by using the transport device as a reducing transport device that returns the second product to the sorting section, the narrowed gaps cause branching grains and spike cuttings in the second product to become single particles during the reduction transport. Is
The burden of re-sorting after reduction transportation is reduced, and the threshing efficiency is improved overall.

がら円滑に搬送される。Further, since the single grain ratio in the grain after threshing becomes higher than the conventional one by the grain transport by the above-mentioned transport device, even when the grain after threshing is dried, the clogging of the dryer due to branch stems, etc. There is no inconvenience. At this time, if the processing projections are inclined along the outer circumference of the transport surface of the transport helix, the processing projections do not obstruct the route of the grain being transported more than necessary, so the kernels are branch stems or panicles. And the like are smoothly conveyed while being made into single particles.

る。Further, in the case where the conveying member is provided with the treating member, the treating member pushes out the grain being conveyed in the outer circumferential direction of the spiral, so that the grain is positively brought into contact with the inner peripheral surface of the conveying cylinder and It is possible to further promote the singulation of cut grains and branch stem grains.

The single graining mechanism does not require a special space for mounting and has a small number of parts, so the mechanism is simple and advantageous in terms of cost.
