Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a thresher handling room in which threshing can be performed at a high flow rate by removing stuck particles in the handling room and preventing leftovers from occurring. Regarding the structure.

[Prior Art] Conventionally, in a thresher configured by connecting a dust-feeding port provided on the rear side of a handling chamber containing a handling barrel to a processing barrel chamber, the above-mentioned feeding unit that takes in unprocessed substances is used. The dust port had a structure in which it was continuously connected to the rear of the end of the handling room.

[Problems to be solved by the invention] Therefore, when high-flow threshing treatment is performed in the handling room, unprocessed substances are taken into the dust-sending port from the end side of the handling room, and thus the end side of the handling room. There was a problem that a large amount of stab particles remained attached to the straw to be discharged more, and it was left unhandled.

[Means for Solving the Problem] The present invention solves such a problem and makes it possible to efficiently perform high-flow threshing processing. Therefore, the handling cylinder (1) is incorporated. A threshing machine in which a dust inlet (3) provided on the rear side of the handling chamber (2) is continuously connected to the processing chamber (4) in a threshing machine having a large diameter with a handling tooth (17) on the outer circumference. On the terminal side of the body (1a), a small diameter handling body (1b) having a longer handling tooth (18) than the handling tooth (17) of the main handling body (1a) is continuously provided on the outer periphery of the handling body (1). ) Is formed on the outer peripheral side between the main handling cylinder (1a) and the small-diameter handling cylinder (1b), and a front-side handling chamber (2a) having a dust inlet (3) and a small-diameter handling barrel (1b) The gap between the outer peripheral surface and the inner surface of the handling chamber is wider than the gap between the outer surface of the main handling cylinder (1a) and the inner surface of the handling chamber (2b). Arrange a partition plate (5) to partition (2) It is composed.

[Operation] Therefore, when a high-flow threshing process is performed by the main handling cylinder, the unprocessed matter is guided to the partition plate and is sent to the dust-sending port and processed in the processing cylinder chamber. Straw that passes through is treated well so that the sticking particles can be successfully combed off in the wide space around the outer circumference of the small-diameter handling cylinder and that there is no leftover residue.

Example Next, an example shown in the drawings will be described.

FIG. 2 is a side sectional view of a thresher mounted on a combine, showing a lower part of a handling room (2) having a grain culm supply port (6) at one end and a straw outlet (7) at the other end. A crimping net (8) is stretched over the front of the handling room (2), and a culm and a feed chain (9) are installed up and down on the front side of the handling room (2). A dust sorting chamber (10) is provided, and a dust collecting cylinder (11) is laid horizontally at the rear of the chamber (10) to swing from below the handling chamber (2) to below the dust sorting chamber (10). A dynamic sorting body (12) is extended, a compressed air fan (13), a 1st spiral conveyor (14), a 2nd spiral conveyor (15), etc. are arranged below it, and a straw cutter (16) is provided at the rear of the machine body. ) Is deployed and configured.

The handling cylinder (1) is mounted inside the handling room (2),
The handling cylinder (1) is formed by continuously connecting a small diameter handling cylinder (1b) to the end side of a large diameter main handling cylinder (1a) similar to the conventional type.
A large number of handle teeth (18) with a high height are provided on the outer peripheral surface of the small-diameter handle body (1b) in which the outer peripheral side has a large space by implanting the same handle teeth (17) on the outer periphery of a). A partition plate (5) is disposed on the outer peripheral side between the main handling cylinder (1a) and the small diameter handling cylinder (1b) with a gap through which grain culms can pass. A dust delivery port (3) is formed at a rear side portion of the handling chamber (2) which is on the front side of the portion of 5) and is on the rear side of the end of the main handling cylinder (1a).

The handling room (2) is a front handling room (2) having a dust inlet (3).
a) and the small diameter handling cylinder (1b) outer peripheral surface and the handling chamber inner surface are wider than the gap between the main handling cylinder (1a) outer peripheral surface and the handling chamber inner surface. It is partitioned with a gap that allows it to pass through.

Further, the processing chamber (4) whose starting end side communicates with the outside of the dust sending port (3) is arranged so that the dust exit port (19) on the end side is opened at the rear part of the dust sorting chamber (10). In addition to extending, a crimping net (20) is stretched under the processing cylinder chamber (4), and the processing cylinder (4a) is rotatably and rotatably mounted on the processing cylinder chamber (4). A screw (21) is mounted on the outer circumference of the processing cylinder (4a) on the starting end side, and a large number of processing teeth (22) are implanted on the outer circumference of the remaining processing cylinder (4a).

Therefore, when a high-flow threshing process is performed by the main handling cylinder (1a) at the time of work, the unprocessed material is taken into the dust delivery port (3) while being guided by being partitioned by the partition plate (5) and the processing cylinder. In the chamber (4), the treatment cylinder (4a) treats it in the same manner as the conventional type, and the straw that passes over the partition plate (5) is treated in a wide space around the outer circumference of the small diameter treatment cylinder (1b). Teeth (18)
The stab grain is successfully combed off by the group and processed so that there is no leftovers, and the straw is discharged from the straw mouth (7) without taking out the grain.

[Advantage of the Invention] As described above, according to the present invention, since the dust inlet (3) is provided in the front handling chamber (2a) by the partition plate (5), the dust handling port (3) is provided by the main handling cylinder (1a) having a large diameter. The unprocessed material when the high-flow threshing process is performed can be taken into the dust inlet (3) and guided in the processing chamber (4) while being guided by the partition plate (5). The high-flow threshing treatment can be performed well, and the small-diameter drum (1b) connected to the end side of the large-diameter main drum (1a) has its teeth (18) The rear handle chamber (2b) is formed longer than the handle teeth (17) of the handle cylinder (1a), and the rear handle chamber (2b) has a small gap between the outer surface of the handle cylinder (1b) and the inner surface of the handle chamber (1a). Since it is formed so as to be wider than the distance between the outer peripheral surface and the inner surface of the handling room, it is possible to widen each straw interval of the straw that has passed through the partition plate (5) in the wide space of the rear handling room (2b). ,And This straw can be combed satisfactorily with the long handle teeth (18) of the small-diameter barrel (1b), so that the stab particles of the straw can be combed well and there is no leftover residue. It can be processed.

In this way, it is possible to efficiently perform the removal and residual treatment of the sticky grains and effectively perform the threshing process at a high flow rate. Have.
