DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a process for treating a threshing product after threshing by a handling cylinder, which is mounted on a combine for harvesting cereals or a stationary threshing sorting device. The present invention relates to an improvement of a so-called parallel processing cylinder type threshing / sorting apparatus of a type provided substantially parallel to a cylinder.

[0002]

2. Description of the Related Art Conventionally, a parallel processing cylinder type threshing / sorting apparatus of this kind is disclosed in, for example, Japanese Utility Model Laid-Open No. 61-34847 (1st edition).
And FIG. 2) and Japanese Utility Model Laid-Open Publication No. 1-108045 (see FIG. 3 and FIG. 4). Below, a swing sorting mechanism is provided so as to extend in the axial direction of the handling cylinder, and above a terminal end of the swing sorting mechanism, a sorting chamber communicating with a suction-type dust exhaust fan to the outside of the machine is provided. On the other hand, at the part opposite to the feed chain with the handling cylinder interposed, a processing cylinder having at least a part of the outer periphery surrounded by a sorting net, the axis of the processing cylinder being substantially parallel to the axis of the handling cylinder Arranged in a shape, and below the swing sorting mechanism,
The configuration is such that a Karamin fan is provided for the swing sorting mechanism.

Further, Japanese Utility Model Application Laid-Open No. 62-186625.
JP-A-62-4392 and JP-A-61-17792.
Japanese Patent Application Laid-Open No. H10-20964 discloses that the position of the suction type exhaust fan is opposite to the side of the feed chain, or an outer wall is provided on the outside of the machine body with respect to the feed chain.

[0004]

However, as shown in FIGS. 1 and 2 of Japanese Utility Model Application Laid-Open No. 61-34847, the suction port of the suction-type dust discharge fan is located at an intermediate portion in the longitudinal direction of the processing cylinder. And at a position close to the outer circumference of the processing cylinder,
The thresh-processed material that does not fall from the crimped mesh surrounding the lower surface of the handling room is near the point where it is passed from the end of the handling cylinder to the starting end of the processing cylinder, before being processed by the processing cylinder. It is discharged out of the machine by the suction type dust discharge fan, and is also discharged out of the machine by the suction type dust discharge fan at the terminal end of the processing cylinder without undergoing the swing sorting operation.

[0005] Although the threshing material guide plate is provided at the transfer portion from the crimping net of the handling cylinder to the processing cylinder, it is provided at the end of the crimping net, so that its guiding action is sufficiently exerted. However, there is a problem that lumps of grain stalk stagnate between the handling cylinder and the processing cylinder.

Similarly, as shown in FIG. 3 of Japanese Utility Model Application Laid-Open No. 1-108045, when a suction fan is disposed close to a terminal end of a processing cylinder without a sorting net, the processing cylinder is processed. Then, the thresh-processed material that has not fallen from the sorting net is directly discharged to the outside of the machine via the suction fan, and the processing cylinder and the suction fan are viewed from above as shown in FIG. Even if they are separated from each other with the swing sorting mechanism in between,
If the end of the processing cylinder is directly exposed to the outside of the machine, the thresh-processed material that has not fallen from the sorting net is directly discharged to the outside of the machine. There is a problem that the grain mixed in the threshing product from the part is discharged to the outside of the machine, and the loss increases.

Further, as disclosed in FIG. 2 of Japanese Utility Model Application Laid-Open No. 62-186625, there is no guide plate to the portion of the handling cylinder where the crimp net is not attached and to the transfer portion of the processing cylinder. At the beginning of the processing cylinder, a spiral for taking in is provided and the structure is complicated, and when the processing cylinder is on the feed chain side and the suction type dust exhaust fan is arranged on the opposite side, the airframe There is a problem that the wall has a lot of irregularities and requires maintenance and maintenance work after the harvest time, and there is a concern that the contact with the uncultivated grain culm increases and the grain culm may be knocked down. In the plan view of FIG. 1 of Japanese Patent Application Laid-Open No. 61-177922, since the exhaust blades at the end of the processing cylinder protrude toward the suction type dust exhaust fan, the exhaust is discharged outside the machine and loss occurs. There were many problems.

An object of the present invention is to solve these problems and to provide a threshing and sorting apparatus capable of reducing the loss of cereals to be harvested.

[0009]

In order to achieve the above-mentioned object, in order to achieve the above object, an oscillating sorting mechanism is provided so as to extend in the axial direction of the handle cylinder and to set the working width in the axial direction to the handle cylinder and the side of the handle cylinder. Widely arranged so as to correspond to the falling width of the leaked material from the disposed processing cylinder, it is possible to sufficiently swing and sort even if there is a large amount of threshing processed by the handling cylinder and the processing cylinder A communication part is formed so that the thresh-processed material that does not fall from the crimping mesh is passed from the end of the handling cylinder to the outer circumference of the starting end of the processing cylinder, and the crimping net of the handling cylinder is attached. The lower end of the threshing process guide plate, which is inclined at a gentle angle so as to be substantially in the middle of the working width of the swing sorting mechanism, is set at the connecting portion between the communicating portion and the receiving net of the processing cylinder, and threshing is performed. The guidance of the processed material is smooth and free from stagnation. At the lower part of the swing sorting mechanism, a Karamin fan for the swing sorting mechanism is provided, and the suction port of the suction type dust discharge fan is sorted on the opposite side of the end of the processing cylinder across the swing sorting mechanism in plan view. The suction type dust exhaust fan is disposed on the side plate of the chamber, and the outer wall of the suction type dust exhaust fan is positioned inward of the threshing apparatus from the feed chain to suck dust and the like.

[0010]

With this configuration, the thresh-processed material that does not fall from the crimped mesh surrounding the lower surface of the processing chamber can be disposed on the processing cylinder side at the communication portion between the processing cylinder and the starting end of the processing cylinder. It is guided again, is threshed again, and falls from a sorting net attached below the outer periphery of the processing cylinder to a swinging sorting mechanism below the sorting net.

In this case, the thresh-processed material falling from the sorting net is subjected to the swing sorting operation by the swing sorting mechanism while being subjected to the wind sorting by the wind from the Karino fan. Also,
The straw waste that could not fall from the sorting net also dropped from the end of the processing cylinder onto the swing sorting mechanism and was subjected to the action of swing sorting and wind sorting. The air is discharged from the suction port of the suction type exhaust fan to the outside of the processing drum on the side opposite to the end portion of the processing cylinder with the sorting mechanism interposed therebetween.

Further, the lower end of the threshing process guide plate, which is arranged at a gentle angle to the portion of the handling cylinder where the crimping net is not attached and the transfer portion of the processing cylinder, is moved to the middle of the working width of the swing sorting mechanism. Since it is set, the thresh-treated product is reliably guided, the incorporation into the processing cylinder is stable, and no grain lumps are generated.

Therefore, according to the present invention, in a threshing / sorting apparatus provided with a processing cylinder in parallel with the handling cylinder, the threshing material that does not fall from the crimp mesh in the handling room is transferred from the handling cylinder to the processing cylinder side. The effect that the processing cylinder and the suction type exhaust fan are separated from each other with the swinging sorting mechanism therebetween in a plan view while being able to perform the processing smoothly and reliably can improve the sorting performance for threshing products. Having.

Since the side plate of the threshing machine body has less unevenness, there is no contact between the grain stalk and the machine body, and the effect of simplifying the structure for attaching detachable covers to the machine body is achieved. .

In this case, the processing cylinder 26 is disposed at a height where the receiving net 28 as a sorting net for the processing cylinder 26 is higher than the crimp net 11 surrounding the lower surface of the handling room 9. . Then, between the starting end side of the receiving net 28 in the processing cylinder 26 and the dust outlet 9a at the end of the crimping net 11, the dust is discharged obliquely upward from the dust outlet 9a toward the processing cylinder 26. An extended threshing treatment guide plate 27 is provided such that the lower end is located at about the middle of the working width of the swinging and sorting mechanism 15, and large pieces of straw and the like that have not fallen from the crimping net 11 in the handling room 9. A communication portion is provided to allow the threshing material to be passed from the dust outlet 9a to the start end of the processing cylinder 26.

Further, as shown in a plan view (see FIG. 3), one side plate 29 forming one side surface of the sorting chamber 14 has an end portion side of the processing cylinder 26 with the swing sorting mechanism 15 interposed therebetween. On the opposite side, the suction type dust exhaust fan 30 is connected to the suction port 30 a of the dust exhaust fan 30.
The inside of the side plate forming one side of the sorting chamber 14 is mounted so as to face the inside, and is provided to the inside of the machine from the feed chain 24. In the above-described configuration, the grain culm transported by the feed chain 24 is threshed by the handling cylinder 10 in the handling room 9, and is then passed from the rear end of the feed chain 24 to the straw chain mechanism 25, and is rearward. It is transferred to the waste cutter device 7.

The grain that has been threshed in the handling room 9 and has fallen from the eyes of the crimping net 11 passes through the feed pan 15a and the sorting net 15d in the swinging and sorting mechanism 15 and is placed in the first receiving gutter 1d.
8, the large threshing products such as straw chips that did not fall from the crimping net 11 in the handling room 9 pass through the threshing product guiding plate 27 from the dust discharge port 9 a to the processing cylinder 26.
After being threshed and processed by the processing cylinder 26, the upper surface of the horizontal beam sheave 15b in the swing sorting mechanism 15 is placed on the receiving screen 28 surrounding the lower periphery of the processing cylinder 26,
She falls while being selected by the wind from the Karino fan 17. As shown in FIG. 2 and FIG. 3, large pieces of straw that do not fall from the eyes of the receiving net 28 are located between the end of the receiving net 28 and the rear end side plate of the sorting chamber 14 (that is, the outer peripheral end of the processing cylinder 26). Unit side) onto the straw rack 15c of the swinging sorting mechanism 15. Due to the sorting wind from the Karino fan 17 and the oscillating motion of the oscillating sorting mechanism 15, heavy objects fall from the horizontal sheave 15 b, and large straw debris falls from the upper surface of the horizontal sheave 15 b. After being discharged to the outside of the apparatus via the rack 15c, light ones are selected by the suction type dust discharge fan 30 so as to be sucked.
