に排出されていたのである。 By the way, in this type of threshing machine, the grains and straw waste separated from the grain culm are separated from the grain culm in the handling room by a sorting wind generated by a winnowing machine, and the straw waste sorted here and the straw waste are separated from the above-mentioned handling room. The straw waste discharged from the dust exhaust outlet is discharged outside the machine by the suction blower in the dust removal chamber, but the straw waste sorted by the above-mentioned sorting air and the straw waste discharged from the handling room are It is common for some grains to be included in the form of ears, etc., and in the past, these were discharged from the machine as they were.

A guide plate is installed in each of the holes to guide the straw in a swirling manner, thereby directing some of the grains contained in the straw shavings carried by the sorting wind and the straw shavings discharged from the handling room to the second screw side. At the same time as sorting and collecting, the suction blower in the dust removal chamber is rotated in the same direction as the sorting air guided into the chamber and the swirling direction of the discharged material from the handling chamber to generate a strong swirling flow in the dust removal chamber. , the grains in the dust are further sorted and collected.

Reference numeral 1 denotes the body of the threshing machine, and 2 denotes a handling chamber provided at the upper front part of the machine body. A handling barrel 3 is mounted on a shaft in the chamber, and grain culm is supplied to the chamber at the front of the machine. A feed chain 4 is provided. 5 is a receiving net stretched over the lower surface of the handling room, 6 is a sorting room provided below it, and a swinging sorting plate 7 is installed in the upper part of the room.
However, in addition, a winnower 8 is provided in the front part, and a first screw 9 is installed at the bottom of the chamber, and a second screw 10 is installed behind it, and the end of the second screw and the A second thrower 11 is provided between the upper part of the handling chamber and the upper part of the handling chamber. Reference numeral 12 denotes a dust removal chamber provided above the rear of the fuselage, 13 a suction blower installed on the side wall of the chamber, and 14 a dust removal outlet provided outside the rear of the fuselage. 15
is a guide plate provided inside the rear wall 1a of the fuselage, and the guide plate has a shape having inclined surfaces 15b and 15c guided upward and downward from the top 15a of the tip, so that the sorting air by the above-mentioned winnower 8 is A guide plate connects the lower No. 2 screw 10 side and the upper dust removal chamber 12.
It is designed to be guided in a spiral shape to each side,
Further, the dust outlet 16 of the handling chamber 2 is formed to face the guide plate. Here, the rotational direction a of the suction blower 13 in the dust removal chamber is set to be the same direction as the swirling direction of the sorting air guided to the dust removal chamber.

的に行われることになるのである。 Next, to explain its operation, the grain culm supplied to the handling chamber 2 by the feed chain 4 is threshed by the rotation of the handling drum 3, and the grains and straw waste generated in this case are transferred to the receiving net. 5 and fall into a sorting room 6 below, where they are sorted by a sorting wind by a swinging sorter 7 and a winnowing machine 8, and the first ones are carried out of the machine by an first screwer 9 and put into bags. The second items that have been stored and need to be reprocessed are returned to the handling room by the second screw 10 and thrower 11. However, the straw and garbage sorted by the sorting wind and the straw and garbage discharged from the dust outlet 16 of the handling chamber by the rotation of the handling barrel reach the rear of the machine and are disposed inside the rear wall 1a. At the same time, the relatively light straw debris contained in the straw debris is collided with the guide plate 15, and the relatively light straw debris contained in the straw debris is collided with the upper and lower slopes 15b and 15c of the guide plate. The heavy stalks and the like are led downward to the second screw 10 side, so that the straw waste is sorted out again. Furthermore, since the direction of rotation of the straw waste introduced into the dust removal chamber 12 is the same as the direction of rotation of the suction blower 13, a strong swirling flow is formed, and this swirling flow causes the straw waste to remain until the end. The grains are finally separated and dropped downward to the No. 2 screw side, and a swirling flow is also formed below the guide plate 15 along the inclined surface 15c, and the grains are sorted to the No. 2 screw side. The straw waste mixed with the ear cuts etc. is forced to flow into the upper part of the dust removal chamber 12, and in this way, the sorting in the dust removal part is effectively performed.

するのである。 As described above, according to the present invention, grains such as ear cuts contained in straw waste transported to the rear of the aircraft by the sorting wind and straw waste discharged from the dust exhaust outlet of the handling room are guided. The dust is sorted by the action of the plate and collected on the second screw side, and a strong swirling flow is formed in the dust removal chamber above by the guide plate and the suction blower, and a swirling flow is also formed below the guide plate. By doing so, the straw waste and grains that have been sorted out will be sorted again, which will significantly improve the sorting performance in the dust removal section,
This has the effect of preventing damage such as grains being ejected from the machine or straw and dust getting mixed into the second product.
