Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a rough sorting section for carrying out rough sorting while receiving a processed article leaked from a handling room with a chaff sheave and swinging and transferring it, and a sorted processed article leaked from the rough sorting section. A fine sorting unit is provided for swinging and transferring the grain to selectively leak the grain to the first product collecting unit and dropping the second product onto the second product collecting unit arranged on the lower side in the transfer direction. The present invention relates to a swing sorting device in a threshing device.

[0002]

2. Description of the Related Art Conventionally, in the rocking and sorting device in the above threshing device, the height of each chaff plate is set to be the same so that the tops of all the chaff plates are aligned at the same height. For example, JP-A-6-24]. For this reason, the chaff plates share the loosening action of the processed material on the chaff sheave and the feeding action of the debris to the rear almost evenly.

[0003]

However, according to the above-mentioned conventional structure, the chaff plates share the loosening action of the processed matter on the chaff sheave and the feeding action of the debris to the rear side substantially evenly. To be able to, for example,
When the gap between adjacent chaff plates is set wide, the processed product is caught on the chaff plates and is loosened easily, but it is easy to generate a lot of straw debris that leaks between the chaff plates, while If the interval is set narrow,
Although it is possible to reduce the amount of straw debris that leaks between the chaff plates, it is not enough to catch the treated matter on the chaff plate, so that the treated matter can be loosened sufficiently and the straw debris can be efficiently sent backward. Was difficult. It is also difficult to set the distance between the adjacent chaff plates so that the advantages of the above two cases can be exhibited.

The present invention has been made in view of the above points, and an object thereof is that a treated product is well loosened by a chaff plate, straw debris is easily sent to the rear side, and the chaff plates are accurately sorted. An object of the present invention is to provide an oscillating sorting device in a threshing device that can reduce the amount of straw debris that leaks up to.

[0005]

A characteristic configuration of the present invention is that each of the chaff plates is formed so that an imaginary line drawn by connecting the tops of adjacent chaff plates over all the chaff plates has a wavy shape in a side view. The height of is set.

[0006]

[Function] Since the height of each chaff plate is set so that the virtual line connecting the tops of the adjacent chaff plates over all the chaff plates and drawing a waveform is a side view, It catches on the high chaff plate at the top, and mainly these chaff plates loosen the processed material and send straw debris backward. In this case, even if the distance between the adjacent chaff plates is set to be small enough not to leak a large amount of straw waste between them, the distance between the chaff plates with high tops will be wide, so These chaff plates are easily caught by the chaff plates and are easily loosened, and straw scraps are also easily sent to the rear. That is, according to the above configuration,
Since the processed product is caught on the chaff plate and loosened well, the grain separates from the straw debris and falls from the chaff plate to the fine sorting section, and the straw debris is easily sent backward.
Further, since the distance between the adjacent chaff plates can be set so as not to be too wide, it is possible to reduce the amount of straw debris that leaks between the chaff plates up to the precise selection.

[0007]

[Effects of the Invention] Therefore, the grains easily fall from between the chaff plates onto the fine sorting section, and the straw debris are easily sent to the rear, and the straw debris that leaks between the chaff plates to the fine sorting is reduced. Therefore, it was possible to provide the rocking sorting device in the threshing device capable of improving the sorting ability.

Embodiments will be described below with reference to the drawings. Figure 1
Shows the threshing device in the combine. This threshing device is configured such that the tip portion of the grain culm conveyed while sandwiching the stock by the threshing feed chain 1 is handled by the handling barrel 3 which is driven and rotated in the handling chamber 2, and the threshing processing is performed to receive the net. In the sorting section on the lower side thereof, the processed material leaking 4 is sorted into grain, second rice such as unhulled rice, and waste straw waste, and the grain is stored in a grain tank (not shown),
The secondary product is reduced and reprocessed in the sorting unit, and the waste scraps are discharged to the outside of the machine.

The sorting section is a swing sorting device 6 for sorting the leaked material while swinging and transferring it, and this swing sorting device 6
Kara Minou 7 that supplies sorting wind that blows away scraps and the like to the lower side in the transfer direction, a screw-conveying type first-most item collection unit 8 that collects sorted and leaked grains and stores them in a tank (not shown), falls downward A screw-conveying type second object recovery unit 9 for recovering the second object and returning it to the upper side in the transfer direction of the rocking and sorting apparatus 6, and fine dust blown off by the Karako 7 from the dust outlet 10 to the outside of the machine body. It is composed of a dust removal fan 11 for discharging.

Next, the structure of the swing selecting device 6 will be described. The rocking / sorting device 6 receives the processed material leaked from the handling chamber 2 inside a hollow frame-shaped rocking / sorting case 14 which is rockably driven by a slide guide mechanism 12 and a crank rocking mechanism 13. The coarse sorting section 15 for performing rough sorting while swingingly transferring, and the sorting processed material leaked from the rough sorting section 15 while swingingly transferring, the grain is sorted and leaked to the first thing collecting section 8, and secondly. A fine sorting section 16 for dropping the article on the second article collecting section 9 arranged on the lower side in the transfer direction is provided.

More specifically, the first gren pan 18 that receives the processed material that has been processed and leaked from the net 4 on the upper side in the grain culm transport direction in the handling room 2 and sorts the specific gravity difference, and the transfer of the first glen pan 18. The chaff sheave 19 arranged in the state of being connected to the lower side in the direction, and the second side that is connected to the lower side of the chaff sheave 19 and receives the processing object falling from the dust delivery port 2a
The rough sorting unit 15 is configured by the first pan straw 21 that feeds the scraps of the processed material falling from the Glen pan 20 and the dust inlet 2a to the lower side. As shown in FIG. 2, the chaff sheave 19 is formed by arranging a plurality of chaff plates 19a, each of which is swingably adjustable about a horizontal axis, in parallel, and each chaff plate 19a is integrally formed by an electric motor M via a wire. It is configured so that it can be oscillated to change and adjust the leakage opening of the processed material (see FIG. 2).

As shown in FIG. 2, a high chaf plate 19a and a low chaf plate 19a are formed so that an imaginary line drawn by connecting the tops of adjacent chaff plates 19a to each other over all the chaff plates 19a has a waveform in a side view. The plates 19a are alternately arranged. As a result, even if the spacing between the adjacent chaff plates 19a is set to a length such that the amount of straw debris leaking between them is not too large, the spacing between the chaff plates 19a with high tops is large. Can be widened. Then, in this case, the chaff plate 19a having a high top catches the treated matter, and mainly these chaff plates 19a perform a loosening action of the treated matter and a backward feeding action of straw debris.

A second Straw rack 2 extending downward from the lower end of the first Straw rack 21 in the transport direction.
3 is arranged so that the waste straw waste sent out from the first straw rack 21 is discharged to the outside of the machine body.

A third gren pan 26 is disposed below the end position of the first gren pan 18, and a grate net 27 for lattice grain selection for grain leakage selection is arranged on the lower side of the third gren pan 26 in the transfer direction. Then, the precise sorting section 16
Is configured.

A corrugated feed protrusion 26a is formed on the upper surface of the third Glen pan 26 (the corrugated feed protrusions are also formed on the upper surfaces of the first and second Glen pans 18, 20). The feed protrusions 26a are arranged such that the pitch of the feed protrusions 26a becomes wider toward the lower side in the transport direction. With this configuration, it is possible to sufficiently perform the loosening action of the processed material toward the rear side of the third Glen pan 26, and it is possible to make it easier to drop the grain from the grain sieve 27 to the most object recovery section 8.

A processing amount detection sensor S for detecting the thickness of the processed material layer above the chaf sheave 19 as data of the threshing processing amount is provided above the chaff sheave 19, and the electric motor M is based on this detection information. A control device 28 for automatically controlling the above is provided. That is, when the processing amount is large, the opening degree of the chaff sheave 19 is widened to prevent the processed material from staying, and the scraps of the straw are removed from the second straw rack 2.
3 is controlled to be discharged. Further, when the processing amount is small, the opening degree of the chaff sheave 19 is narrowed to control so that straw debris does not leak to the fine sorting unit 16.

[Other Embodiments] The chaff sheave 19 may be configured by alternately arranging one high chaff plate 19a and a plurality of low chaff plates 19a.

As shown in FIG. 3, the third Glen pan 2 is used.
Regarding the feeding protrusions 26a of No. 6, the feeding protrusions 26c having a narrow width in the front-rear direction and the feeding protrusions 26d having a wide width may be alternately arranged, and the interval p between the adjacent feeding protrusions may be set to be the same. According to this configuration, it is possible to sufficiently perform the loosening action of the processed material, and it is possible to make it easier to drop the grain from the grain sieve 27 to the most object recovery section 8.

It should be noted that reference numerals are added to the claims for facilitating the comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
