Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an axial-flow type threshing device provided with a rice-convex container for feeding threshing products from a handling room to a sorting section in a leaky manner. Regarding

[0002]

2. Description of the Related Art Conventionally, regardless of the type of threshing processed material, the threshing processed material has been constructed so as to be leaked to a sorting section by a rice-concave covering the entire length of the handling room.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, when grains such as buckwheat that are likely to be shredded are treated by the rice-concave, which is long in the treatment product phase direction so as to be suitable for rice and wheat that are difficult to shatter, Most of the grains fall to the sorting part in the front part of the rice-wheat concealed processed material phase direction in the handling room, and most of the fallen parts in the rice-wheat-concave processed material phase backward part are stems and leaves. However, when only the waste is supplied to the sorting section, the sorting efficiency is lowered, and there is room for improvement in terms of improving the sorting efficiency in the processing of millet. An object of the present invention is to make it possible to satisfactorily perform threshing selection processing on not only rice barley but also minor cereals, and to devise a means therefor which is economically advantageous.

[0004]

A feature of the present invention is that in an axial-flow type threshing device provided with a rice-convex container for feeding threshing-treated products from the handling room to the sorting section, the A blind plate is detachably attached to the rear side of the treatment room in the handling room so as to cover it from the handling room side.

[0005]

In other words, when treating rice or wheat that is difficult to shed, remove the blind plate covering the rear part of the rice-concave transfer direction in the processed product transfer direction, and thresh with the rice-concave long in the processed product phase direction. The processed material can be dropped and supplied to the sorting unit to improve threshing and sorting efficiency. When processing coarse grains such as buckwheat that are likely to be shredded, cover the rear part of the rice cabbage concave product transfer direction from the handling room side with a blind plate to remove stems and leaves from the rear part of the concave product transfer direction. It is possible to improve the sorting efficiency by preventing waste such as the like from being supplied to the sorting unit. In addition, it is economically advantageous to simply attach and remove the blind plate rather than preparing a minor grain concave in addition to the rice grain concave and replacing the concave.

[0006]

As a result, not only rice barley but also cereals can be threshed and satisfactorily treated, and it is possible to provide a more excellent axial flow threshing device which is economically advantageous.

[0007]

[Example] As shown in FIG. 1, in constructing an axial flow type threshing device of a whole culm throw type combine, a handling chamber 2 communicating with a feed conveyor 1 for feeding grain culm from a mowing section is formed in the upper part of the case. A sorting unit 3 is arranged below the handling chamber 2, and a rice-convex 4 for feeding grain from the handling chamber 2 to the sorting unit 3 is provided over almost the entire length of the handling chamber.

The handling cylinder 5 is rotatably supported in the handling chamber 2 so as to be rotatable about the longitudinal axis, and spiral handling teeth 6a are attached to the outer peripheral surface of the handling cylinder 5 over the entire length and in a concentric manner. An independent handle tooth 6b is attached to the handle tooth 6a at an appropriate interval in the circumferential direction, and a dust delivery valve 7 for guiding a processed object flowing in the handle barrel circumferential direction along with the rotation of the handle cylinder 5 in the handle barrel axial direction is provided in the handle chamber. It is provided on the top plate 8.

The sorting unit 3 is provided with an oscillating sorting case 3a, a wind-picking Karasu 3b, a No. 1 recovery screw conveyor 9, and a No. 2 reduction screw conveyor 10 to shake the processed material leaked and fed from the concave 4. The moving sorting case 3a swings backward to carry out sieving sorting and wind sorting processing, and the grain is collected by the No. 1 grain collecting screw conveyor 9 and sent to the not-shown Glen tank, which is insufficient sorting. Two
The product is returned from the second product recovery screw conveyor 10 to the front part of the swing selection case 3a by a reduction transfer device (not shown).

As shown in FIG. 2 and FIG. 3, in forming the concave portion 4 for rice barley, a curved plate-shaped bar 4a extending in the circumferential direction of the handling cylinder.
Round bars 4 that are arranged side by side in the axial direction of the handling cylinder and extend in the axial direction of the handling cylinder.
b is passed through the crosspiece 4a, and the concave portion 4 for rice and wheat is divided into two in the circumferential direction of the handling barrel and divided in three in the axial direction of the handling barrel, and six concave unit bodies 4A to 4F are arranged in parallel. I am doing it.

[0013] Of the concave portion 4 for rice and wheat, the rear side portion 1/3 of the processed material in the handling room, that is, the concave unit body 4
E, 4F in a state of covering it from the handling room 2 side, and in a state of being separately attached to the two concave unit bodies 4E, 4F, the two blind plates 11, the bolt 12, the nut 13, and the round bar. Four
In the case of treating rice or wheat which is hard to be shredded, it is detachably attached by the locking member 14 for b, and the blind plate 11 is removed, and the threshed material is sorted by the rice wheat concave 4 long in the processed material phase direction. In the case of dropping and supplying to the part 3 and processing minor grains such as buckwheat that are likely to be shredded, a blind plate 11 is attached and scraps such as stems and leaves are sorted from the rear side portion of the concave 4 in the processed object phase direction. It is configured not to be supplied to Both ends of the blind plate 11 in the circumferential direction of the handling cylinder are attached to the holding frame 4c of the crosspiece 4a.
It is configured so that it will not be lifted by pressing with. The blind plate 11 is attached and detached by extracting the concave unit bodies 4E and 4F to the outside.

As shown in FIGS. 4 and 5, the concave unit body 4 is formed to form the concave unit bodies 4A to 4F.
Connecting plate 15 attached to the left and right center on the lower end side of A to 4F
, The bolt insertion port 16 and the nut 17 are provided so as to be distributed to the left and right, and concave units 4A and 4B having the same specifications are provided.
C and 4D, 4E and 4F, one bolt insertion port 1
Connecting bolt 1 screwed to the other nut 17 through 6
8 and one of the nuts 17 are screwed together and connected by a positioning pin 19 inserted into the other bolt insertion opening 16.

[Other Embodiments] The structure of the concave cave 4 for rice and barley may be one constructed by braiding a wire rod. The range of the rear portion of the concave portion 4 for rice grains covered with the blind plate 11 in the processed product phase direction can be appropriately changed. As shown in FIG. 6 and FIG. 7, when there is a high risk of adhesion due to the juice of blue leaves such as summer buckwheat noodles and early buckwheat noodles, the front side portion 2 /
3, the perforated plate 21 with the long hole 20 is detachably attached by the locking member 24 for the bolt 22, the nut 23, and the round bar 4b in a state of covering them from the side of the handling chamber 2 to prevent adhesion. Good.
