Description

[Detailed description of the invention] The present invention relates to a screw type threshing device.

The screw auger, which was originally used to convey grain in the axial direction, can be used to increase the diameter of soybeans, wheat, rice, etc. by enlarging its diameter and giving it a predetermined rotational speed so that the screw blade can maintain the circumferential speed necessary for the crops. In addition to the ability to easily transport the entire amount of input crops, it also has a threshing function.

Also, at this time, if the screw auger's receiving gutter is changed to a receiving net of an appropriate size for the crops, the grains threshed in the handling chamber will leak upward from the receiving net, and the culms such as stems and straw will be removed in the axial direction. It also has the so-called sorting function of transporting it to the outside of the machine and discharging it outside the machine. This is a screw-type threshing device.

The screw-type threshing device is a new type of threshing device that is highly versatile for various crops and does not place a large load on the sorting mechanism.

The present invention is a further improvement of the above-mentioned threshing device, in which a suction device communicating with the handling room is provided at the rear of the machine body.

As mentioned above, the screw-type threshing device has a screw installed in the handling barrel, and threshes by causing "lateral displacement" of the crop between the screw and the receiving net. By installing a suction device behind a certain handling cylinder, it sucks and removes the dust generated in the handling room, and also performs a sorting function at the same time.Even if the suction power is increased, there is a screw in the handling cylinder. Therefore, dust containing grains is simultaneously sucked out of the handling chamber along with the wind in the handling chamber, but the suction force is blocked by the screw and is therefore weak, making it difficult for losses to increase.

Furthermore, even if the handling cylinder becomes longer, the suction force sucks up the accumulations and dirt from the handling opening, so there is less dust generation and loss is less likely to occur.

The embodiments shown in the drawings will be described below.

(1) is the handling room of the threshing device, in which the handling cylinder (2) is rotatably mounted, and the threshed grains are collected in the receiving net (3).
) to the Spicy (4) arranged parallel to the handling cylinder axis, and is moved toward its terminal end by the rotating Spicy (4).

During this conveyance process, grains and fine straw waste leak downward from the catch net (6) stretched over the spicier's catch gutter, and only the long straw is carried toward the culm outlet (6). The grains that have leaked through the receiving net (5) fall onto the first gutter (8) on the belt conveyor (7), and are transported to the paddy tank by the screw conveyor (9).

Then, the second material is discharged from the rear of the handling cylinder (2) and discharged by the spiraler (4) toward the discharge culm (6), but on the way, it falls into the second gutter α0) and is ejected from the second gutter. The second item that has fallen is returned to the handling room (1) from the screw conveyor (11) via the thrower (b). (12a
) is its thrower.

Two Spicy (4) shown in the figure are arranged side by side.

(b) is a resistance plate placed in the handling room (1), o4
j is an independent handling tooth formed between the screw teeth (b) of the handling cylinder (2); (1) is a spike tooth provided on the inclined surface ζ on the front surface of the handling cylinder (2).

The present invention is a screw-type threshing device as described above, in which a suction device communicating with the handling room is arranged at the rear of the machine body.

In the illustrated one, a suction device is formed by a fan αη provided on and behind the shaft (2a) of the handling cylinder (2). (To) is the case, and (埒) is the exhaust port.

The suction air is generated by a wire mesh suction port (201) installed on the side plate of the threshing machine.
(21) @Those originating from the rice plant and leaking from the receiving net (5) of Spicy (4) are sorted by second-class suction wind and transported by Spicy (4) towards the discharge culm (6). Crops that can be harvested are also sorted using the suction air.

In addition, the rear of the handling barrel is open, and a suction device is used to suck the inside of the classroom from this open part, so that the suction device can suck up the liquid dust generated in the handling room.

In short, the present invention has a screw in the handling cylinder, which blocks the suction air flowing into the handling chamber as described above.
Therefore, since the suction force is weakened, even if the suction force is increased, the loss is difficult to increase. Furthermore, even if the handling barrel becomes longer, the suction force sucks up the accumulations and dirt from the handling opening (goods), so there is less dust generation and less loss.
