15上面との間の空間に連通している。In the range of the above-mentioned overlap α, a loosely curved upper sorting wind passage 40 is formed between the inner surface of the outer casing 37 and the outer surface of the inner casing 34. The chaff sheave 31 of the rocking sorting board 13 passes through the upper sorting wind outlet 39 through the upper sorting wind passage 41 formed by the upper surface of the wind plate 36 and the lower surface of the feed pan 30.
a While communicating with the space between the lower surface and the upper surface of the Glensieve 31b, a lower sorting air outlet 43 is formed between the lower surface of the upper baffle plate 36 and the upper surface of the lower baffle plate 38.
Through the lower selection air duct 44 formed by the lower surface of the upper baffle plate 36 and the upper surface of the lower baffle plate 38, and the bottom surface of the gren sieve 31b and the most gutter.

The sorting wind a generated in the tangential direction on the outer periphery of the fan body 33 is guided to the inner and outer casings 34, 37 and the upper and lower air guide plates 36, 38, divided at the above-mentioned corner points 45, and sent to both upper and lower surfaces of the Glensieve 31b. Accordingly, the sorting wind b sent to the upper surface of the Glen sieve 31b is combined with the negative pressure generated by the dust suction fan 91 of the straw processing unit 9, and the sorting fins 31 of the sorting fins 31 provided in the chaff sheave 31a are combined. Pass through the gap 31c from the bottom to the top as shown by the arrow c, and the chaff sheave 31a
By floating the above-mentioned objects to be sorted, the fluidity of the straw waste and the separation of the straw waste from the grain are improved, and the dust is sucked into the dust suction fan 91 as shown by the arrow d, and then discharged from the straw discharge passage 92 to the outside. Is discharged.

化することができる。Further, since the squeeze point 45 of the inner casing 34 is close to the outer periphery of the fan body 33, and the upper sorting air passage 40 is open to face the sorting air a,
Since the sorting air generated in the tangential direction on the outer periphery of the fan body 33 is smoothly divided, the change in the flow passage cross-sectional area at the overlapping α portion of the sorting air upward is gentle, and the curvature is small. The loss of wind power is reduced, and the Karato 14 can be made smaller.

And the rear end edge of the air flow rate changing plate 47 is attached to the air flow rate changing shaft 46, and the front end edge of the air flow rate changing plate 47 is moved from the virtual extension line of the inner casing 34 at the threshold point 45 to the outer casing 37.
The angle can be changed up to the position where it abuts against the inner surface.By changing this angle, the space between the lower surface of chaff sheave 31a and the upper surface of gren sheave 31b of rocking sorter 13, and the lower surface of gren sheave 31b and the uppermost gutter 15 are set. It is possible to adjust the ratio of the sorting air sent to the space between.

When the work is completed, the wind direction changing plate 49 is rotated to a position where the front end edge of the wind direction changing plate 49 comes into contact with the lower surface of the upper air guide plate 36. The same gutter 15 can be cleaned by deflecting the dust to the leftmost gutter 15 and blowing away the dust and the like remaining on the most gutter 15 toward the straw processing unit 9.

化することができる。According to the present invention, the fan body is covered with an inner casing slightly larger than the outer diameter of the fan body from the front position to the upper position of the fan body of Karin, and the fan body is positioned obliquely rearward and downward. From the outer casing that gradually increases in diameter from the front to the diagonally upper front position, the inner casing and the fan main body are covered, and the inner and outer casings are overlapped from the front position of the fan main body to the diagonally front upper position of the fan main body. Since the sorting air from the fan body is divided into upper and lower parts, and the sorting air is sent to both the upper and lower sides of the Glen Sieve, the sorting efficiency is improved and large-scale and precise sorting can be performed. Can be miniaturized.

Furthermore, since the change in the cross-sectional area of the flow passage is gentle at the overlapping portion of the sorting wind to the upper side and the curvature is small, the loss of the wind force is reduced and the Karako can be miniaturized.

It is possible to properly adjust the wind force of the upper sorting wind according to the amount of the objects to be sorted, the degree of wetness, etc., and improve the sorting efficiency.

はかることができる。In addition, a wind direction changing plate is provided in the sorting air passage from Karato to the lower part of the swinging sorter so that the sorting wind below the swinging sorter can be deflected in the most gutter direction. The lower sorting wind is blown to the first gutter, and the dust etc. remaining on the same gutter is blown toward the straw processing part, so that the same gutter can be cleaned, and manual cleaning work is simplified, and cleaning is also possible. It is not necessary to provide an opening for the opening and a lid for closing the opening, the structure is simplified, the number of parts can be reduced, and the cost can be reduced.
