［発明が解決しようとする課題］
上述の脱穀装置には、それの扱室１内で脱穀処

で、充分な選別を受けないまま排塵選別室に送り
込まれるようになつたり、排塵口を詰まらせるよ
うになつたりする問題がある。[Problems to be Solved by the Invention] In the above-mentioned threshing device, among the sorting means for sorting the threshed material threshed in the handling chamber 1 of the threshing device, in particular, a The effect of air sorting the discharged non-dust in the sorting air passage 3 is insufficient, and the dust is sent to the dust sorting room without being sufficiently sorted, or the dust exhaust port is clogged. There is a problem.
これは、扱室１の排塵口６から排出される排塵

選別を受けて排塵選別室２に向けて移動していく
ようになるが、選別風の透過が悪いことで、選別
風によるときほぐしを受けずに塊のまま移動する
ようになり、かつ、その移動が鋭いものとなるこ
とによる。 This is because the dust discharged from the dust exhaust port 6 of the handling chamber 1 is often collected in lumps due to entanglement of long pieces of straw mixed therein. The dust that has accumulated in the form of a lump falls directly onto the upper surface of the swinging sorting shelf 8 suspended below the handling room 1, and is subjected to swinging sorting while being exposed to the sorting wind to the dust sorting room. 2, but due to the poor penetration of the sorting wind, the particles are not loosened by the sorting wind and move as a lump, and the movement becomes sharp. .
本発明は、このように、従前の脱穀装置の選別

供することを目的とする。 The present invention has been made in order to solve the problems that have arisen in the conventional sorting means of threshing equipment. Even if the waste is discharged in an accumulated state, it is effectively subjected to the sorting air in the sorting air passage 3, becomes sufficiently loosened, and can be efficiently subjected to air sorting and oscillating sorting. The purpose is to provide a means to do so.
［課題を解決するための手段］
しかして、本発明は、上述の目的のために種々

とが判つた。 That is, the above-mentioned problem is such that the dust accumulated in lumps and discharged from the dust exhaust port 6 of the handling chamber 1 is removed from the swinging sorting shelf 8.
This can be solved by discharging the dust from the dust outlet 6 of the handling chamber 1 by discharging it from the upper surface. It was found that it would be better if the object was exposed to a sorting wind while falling to the upper surface, and was blown up from below.

果となるかとである。 This includes a notch-shaped straw discharge passage 14 that opens toward the feed chain 15 at the bottom of the rear wall 11 of the handling chamber 1.
(or a culm discharge port) has been opened, and its straw discharge passage 1
Since the lower edge 14a of 4 is designed to approximately follow the bottom surface of the receiving net 5, the dust outlet 6, which is opened at the rear end of the bottom side of the receiving net 5, is If the main sorting air is blown away, the main sorting air will be directed to the lower edge 14a of the non-straw passage 14.
As a result, the main sorting air impedes the flow of the main sorting air, and not only does it not have the effect of loosening the dust discharged from the dust exhaust port 6. This may result in worsening the wind selection effect.

果を得たことによるものである。 Therefore, the lower part 11a of the rear wall 11, which is below the above-mentioned straw discharge passage 14, is shown in FIG.
As in the embodiment shown in FIG.
A predetermined distance L from the upper part of the rear wall 11
When the main sorting air out of the sorting air blown out from the air outlet 71 of the Karakin blower 7 is , the lower surface side of the dust exhaust port 6 of the handling chamber 1 is blown upward from the lower front to the upper rear, effectively removing the dust that accumulates in lumps from the dust exhaust port 6. This is because it was possible to efficiently sort out the discharged dust by loosening it and dropping it on the top surface of the swinging sorting shelf 8 in a diffused state.

る。 Therefore, in the present invention, as a means for achieving the above-mentioned object, a handling chamber is installed in the upper part of the front end side of the fuselage, in which the handling barrel is accommodated.
At the bottom of the machine below the handling room, there is a sorting air passage for sorting the threshed material discharged through the receiving screen and dust outlet of the handling room, and the sorting wind blows from the lower front to the upper rear. The windshield blower 7 is installed at the front end of the sorting air passage, and a dust sorting chamber connected to the rear end of the sorting air passage is provided on the rear side of the body. An oscillating device is placed at a position across the sorting air path from below to the dust sorting room, and supplies the leakage from the receiving net and the discharge from the dust outlet to the sorting air path while oscillatingly sorting it. In a threshing machine that is provided with a sorting shelf and has a notch-shaped straw removal passage that opens toward the feed chain in the lower part of the rear wall of the handling chamber, the lower part of the rear wall that is below the straw removal passage on the rear side is It is arranged at a position that is set back by a predetermined distance from the upper part of the rear wall above the dust exhaust passage and raised by a predetermined distance from the bottom of the receiving net, and the air is blown from the outlet of the Karachi blower 7 to the swing sorting shelf. A threshing device characterized in that the sorting wind blowing through the front end side of the threshing machine toward the upper surface side blows up between the upper surface side of the swinging sorting shelf and the lower surface side of the dust exhaust port toward the dust sorting chamber. This presents a sorting device.

切れ類の分別を良好にする。 Therefore, while the threshing dust discharged from the dust outlet 6 falls onto the top surface of the swing sorting shelf 8, it is blown up by this sorting wind, and the dust is formed into clumps. Even if the dust is released from the dust exhaust port 6, it is loosened during the fall and falls on the top surface of the swinging sorting shelf 8, so that wind sorting and sieving on the top surface of the swinging sorting shelf 8 are not possible. To be efficient and to improve the separation of straw scraps.

The sorting air that is directed straight toward the upper part of the internal cavity of the dust sorting chamber 2 through the lower surface side does not become an obstacle, and the sorting air that is blown out from the air outlet 71 of the Karachi blower 7 passes through the dust outlet of the handling chamber 1. Since the dust discharged from 6 is blown up, even if the dust accumulates in a lump and is discharged, it is loosened by the sorting air and placed on the top surface of the swinging sorting shelf 8. Since the dust is allowed to fall in a diffused state, the wind separation process for the waste becomes extremely efficient.
