[Industrial applications]

 The present invention relates to a threshing device in a combine, for example, in which grain culms cut by a shaving section are threshed by a handling cylinder and a processing cylinder of a threshing section.

[0002]

[Prior Art]

 Conventionally, the blast of the sorting wind for sorting straw etc. is performed by the Kara mochi provided in the swing sorting chamber, and the suction and discharge of this sorting wind is provided, for example, on the left and right sides of the threshing section below the 4th gutter. It is generally performed by an intake and exhaust fan.

[0003]

[Problems to be solved by the device]

 However, after the sorting wind from Kara No. passed through the chaff sheave above the No. 1 conveyor, this sorting wind was blown up along the No. 4 gutter to the No. 4 side, and to the rear straw cutting section. There was an inconvenience that hindered the collection of stab particles by, for example, blowing out dust or accelerating the retention of dust on the 4th gutter.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, in the structure in which the parallel processing cylinder is arranged on the side of the rear end of the handling cylinder, it is located slightly forward of the dust outlet of the processing cylinder and below the No. 4 gutter at the rear of the handling cylinder. In addition, by installing an axial-flow intake / exhaust fan that faces the rotating shaft in the longitudinal direction of the machine, it is possible to prevent the sorting air from Kara no Tsumugi from blowing out from the 4th port, and to eliminate the loss by the intake / exhaust dust fan. Efficiently ejecting out of the machine from the 3rd port to prevent the accumulation of dust on the 4th gutter and improve the efficiency of collecting stab particles, improving the accuracy and efficiency of this selection. It is what makes them.

A sorting board, a feed pan (27) located below the crimp net (25), a chaff sheave (29) located below the rear part of the crimp net (25) and a dust outlet (28), and the chaff sheave. (29) The glensieve (30) arranged below and the rear part of the chaff sheave (29) are connected to each other. The rocking sorting board (26) is constituted by the installed Straw rack (31).

Further, in the figure, (32) is a Kara-mino which sends a sorting wind toward the sorting board (26), and (33) is connected to the fried cylinder to take out the grain into the grain tank (17) 1. No. 2 conveyor, (34) is a No. 2 conveyor for returning No. 2 material to the rocking sorting board (26), and (35) is an axial flow type dust collecting and exhausting fan disposed above the Straw rack (31), Grains that have been threshed by the handling cylinder (6) and the processing cylinder (7) are sorted by an oscillating sorting board (9), and only the sized grain is taken out to the grain tank (17) and the straw is drained in the straw chain. (12) It is configured to be sent to the straw processing section (11) via (13) and discharged to the outside of the machine after being cut by the cutting cutter (36).

The processing cylinder (7) is arranged parallel to the handling cylinder (6) and on the rear right side of the handling cylinder (6), while the suction / exhaust dust fan (35) is disposed behind the handling cylinder (6). It is arranged on the left side of the cylinder (7), and is located slightly below the dust outlet (37) of the processing cylinder (7), below the No. 4 gutter (38). The rotating shaft (39) faces the longitudinal direction of the machine body, and a partition plate (40) is provided between the fan (35) and the processing cylinder (7) on the right side. It is configured to prevent the leaked substances from the processing cylinder (7) from being directly discharged to the outside of the machine by the suction and discharge fan (35) and improve the fan performance.

Further, as shown in FIG. 6, in the dust suction / exhaust fan (35), a fan drive case (41) fixed to the threshing left side plate (4a) supports a fan rotation shaft (39), and the feed chain (35). 5) The sprocket shaft (42a) of the idle sprocket (42) at the feed end is input to the gear case part (41a) of the drive case (41) to rotate the blade (35c) of the suction / exhaust dust fan (35). 4) without blowing the sorting wind from Karato (32) passing through the chaff sheave (29) along the upper surface of the No. 4 gutter (38) from the No. 4 mouth (43) to the cutting cutter (36) side. The gutter (38) is configured so that it can be discharged more efficiently to the fuselage along the inner side than the third opening (44).

Further, the suction / exhaust dust fan (35) is integrally formed with a conical airflow direction portion (35b) at the rear end of the shaft boss (35a) so that the suction air from the upstream side of the fan (35) flows downstream. When flowing to the side, the wind direction portion (35b) allows the wind to flow to the outside of the outer diameter portion over a wide range so that the normal wind can be sucked outside the outer diameter portion without wind blowback. I am configuring.

The present embodiment is configured as described above, and during the rocking and sorting operation of the degrained grains by the rocking and sorting board (26), the sorting wind from the Karako (32) is the first conveyor. (33) After passing through the upper chaff sheave (29), the suction / exhaust fan (35) does not blow up along the upper surface of the fourth gutter (38) toward the fourth opening (43). It is sucked by the suction force along the inside of the No. 4 gutter (38) and is exhausted to the outside through the No. 3 port (44). As a result, the blowing of air from the No. 4 port (43) toward the cutting cutter (36) as in the conventional case is prevented, the accumulation of dust and the like on the No. 4 gutter (38) is eliminated, and the No. 4 port (43 It is possible to greatly reduce the popping out of grains due to the wind from 43) and the obstruction of the collection of sting grains due to the accumulation of dust. At the same time, the collection of sting grains falls not only downward but also downward. It is promoted by the effective suction air from the plant, which enables highly accurate and highly efficient sorting work such as grain loss.

The drive source of the suction / exhaust dust fan (35) may be the handling cylinder (6) or the processing cylinder (7) in addition to the feed chain (5).

Also, by using an independent motor, the scattering speed of grain can be suppressed to the minimum by controlling the optimum rotation speed according to the working condition such as wet material, traveling, overdrying, start of cutting, and end of cutting. It is also possible to maximize the sorting ability.

Further, since the air intake / exhaust fan (35) is provided with the wind direction portion (35b), the blind spot portion of the wind which is located outside the outer diameter portion of the conventional blade and does not blow wind is a reverse wind. In addition, it is possible to make the air flow in a wide range, eliminate dust buildup and clogging due to wind blowback in this blind spot, and make the flow of the selection wind a normal wind to further improve the selection performance. It is possible.
