Description of the Related Art In an oscillating sorting rack for sorting grains while oscillating and receiving thresh of a combine, threshing is provided on the starting end side. A transfer plate for receiving the threshing and transferring it by rocking is provided, and a chaff sheave for sorting the grains while receiving and rocking the threshing material transferred by the transfer plate is provided. For this reason, since the threshing material transferred from the transfer plate to the upper surface of the chaff sheave is large and the layer is thicker, it is difficult to sort, and the sorting is effectively performed as the thresh is transferred to the end portion of the chaff sheave. It will be. Therefore, the present invention aims to improve the sorting efficiency by effectively performing the sorting at the starting end of the chaff.

And the configuration of the threshing rocking sorting device. The threshing material dropped from the threshing room by the swinging of the swing sorting shelf 3 is received on the upper surfaces of the transfer plate 1 and the chaff sheave 2 and transferred. Of these, the thresh received on the upper surface of the transfer plate 1 is collectively transferred to the upper surface of the chief sheave 2 at the end portion, and is subjected to the swing sorting operation by the chief sheave 2 therefrom. At the starting end of the chaff sheave 2, the threshing material is floated by receiving the sorting wind guided by the sub-sorting air passage 8, so that the threshing material can be easily transferred and sorted. In this way, the sorted material leak-separated by the chaff sieve 2 is sorted by the lower sieve or the like, and is sorted by the sorting wind guided through the main sorting air passage 6. In this manner, the thresh sent from the upper surface of the transfer plate 1 to the upper surface of the chaff sheave 2 is blown up by the sorting wind guided from the sub-blowing port 7 of the Karamin 4 through the sub-sorting air passage 8, so that threshing is performed. Even if the material delivery layer is thick, the transfer sorting action is promoted, and the swinging sorting of the thresh can be performed efficiently. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A combine threshing apparatus 9 has a handling cylinder 10 mounted on a threshing chamber 12 by a fore-aft handling cylinder shaft 11 and a grain culm transfer port along one side of the threshing chamber 12.

A culm discharge device 21 for discharging to the outside is provided, and a suction discharge device 22 is provided in the dust chamber 20. The swing sorting shelf 3 is provided below the space between the threshing chamber 12 and the dust discharge chamber 20 and is supported so as to be swingably driven with respect to the threshing machine frame. In addition, below the swinging sorting shelf 3, the Karamin 4 and the main and sub-sorting air paths 6, 8 and the first receiving gutter 23 and the second receiving gutter 24 are arranged. [0008] 25 is a cockpit, 26 is a cockpit, 27 is a Glen tank for taking out and containing the grains threshed by the threshing device 9,
Reference numeral 28 denotes a culm cutter for shredding the culm. E is an engine. The rocking sorting shelf 3 is provided with a transfer plate 1 having a feed protrusion formed below the threshing net 18, and the inclined plate 29 is arranged at a constant interval from the end of the transfer plate 1 to the rear thereof to form a plate. Is provided, and receives the threshing material transferred from the transfer plate 1 and the straw debris discharged from the culm opening 17 and swings and transfers the same to mainly sort out the grains in a leaking manner. At the end of the chief sheave 2, a straw rack 30 is disposed below the dust chamber 20 for swinging and transferring the straw wastes to the rear. Reference numeral 31 denotes a grain sieve, which receives the sorted material leaked from the chaff sieve 2 and sorts out the grains by leaking. The Karamin 4 is provided at the lower part of the transfer plate 1, opens the main air outlet 5 toward the rear main air passage 6, and opens the sub air outlet 7 toward the auxiliary air passage 8. When the fan 32 rotates, compressed air is blown out from these blow-off ports 5 and 7, and the suction and dust is discharged from the main selection air path 6 and the sub-selection air path 8 through the selection gap of the swinging selection shelf 3. It flows as suction air by the machine 22. A wind split 3 is provided between the main air outlet 5 and the sub air outlet 7.
3 is provided, and the rear end face 34 of the wind split 33 is formed as an inclined surface descending rearward, and the upper plate 35 is extended so as to slightly project rearward.
The lower plate 36 extends rearward from the upper plate 35, and the guide plate 37 at the front end of the Glen 31 faces the rear side of the rear end face 34. The guide plate 37 is located at an appropriate interval lower than the rear extension surface of the upper plate 35, and even if the swing sorting shelf 3 swings back and forth, the upper end portion and the rear end surface 34 of these upper plates 35.
It is configured not to contact with. A sub-blower port 7 is formed between the upper plate 35 and the guide plate 38 facing the upper side, and the distance between the upper plate 35 and the guide plate 38 is wide on the Karamine 4 side. 8
The sides are sequentially narrowed so as to become narrower, so that the air is blown faster. The sub-sorting air path 8 is formed between the guide plate 37 integrated with the swing sorting shelf 3 and the guide plate 39 provided on the lower surface of the terminal end of the transfer plate 1 so as to be narrowed down in order. The sorting wind guided by this is blown up to the swing sorting shelf 3 through the space 40 between the front end of the transfer plate 1 and the inclined plate 29 at the front end of the chaff sheave 2 facing the rear. are doing. Also, this inclined plate 2
A gap 41 is formed between the lower edge of the guide 9 and the upper edge of the guide plate 37 so as to open from the sub-selection air passage 8 to the upper surface of the grain 31. It is configured to be guided onto the grain 31. In this way, the sorting wind blown out from the sub-blowing port 7 is guided to the spacing section 40 through the sub-selecting wind path 8 at an increased wind speed, so that the wind pressure blown up the spacing section 40 upwards. As a result, the threshing material sent out onto the transfer plate 1 onto the interval portion 40 is floated here, so that straw chips and the like are easily blown to the rear portion of the chaff sheave 2, so that the kernels are easily leaked and shaken. The dynamic transfer sorting operation is performed promptly and smoothly. The main air outlet 5 has two upper and lower wind splitters 42, 43.
The front end 44 of the wind splitter 42 is located behind the front end 45 of the upper wind splitter 33 and the front end 46 of the lower wind splitter 43. The wind receiving area from the side 32 is widened so that the wind blown between the wind splitters 33 and 42 is increased to improve the wind contact along the grain 31 in the main sorting wind path 6. It is composed. The rear end surfaces 34, 47, 48 of the wind splits 33, 42, 43 of each of these steps are both inclined backward and downward.
It is formed in a step shape, and the rear end face 48 of the lowermost step is
Looking up. In FIG. 4, the difference from the above example is that the inclined plate 29 at the front of the chief sheave 2 has a double structure, and the interval between the upper part and the lower part is narrower to form a slit-shaped jet path 49. The blowing path 49 has such an interval as to prevent the kernel from leaking, and facilitates upward blowing of the sorting wind. Although the thresh 2 has a large amount of threshing material at the front end thereof, the fumarolic gas flows because the leakage of grains and straw chips flows down the upper surface of the front inclined plate 29 and does not flow down the fuze passage 29. The resistance of the sifting wind on the road 29 to blow-up is small, and the transfer sorting on the chaff sheave 2 is improved. In FIG. 5, the difference from the above example is that the sheave interval 50 of the inclined plate 29 at the front part of the chief sheave 2 is set so that the upper part is gradually narrowed with respect to the lower part. By increasing the wind speed that blows through to the upper surface of the
Improve the transfer sorting effect. The cross section of the inclined plate 29 has a triangular shape. In FIG. 6, the difference from the above example is that a wind split 51 is provided in the sub-selection air passage 8, and the selected wind blown out from the sub-blower 7 is separated by the wind split 51 into the chaff sheave 2.
Dividing flow is guided to the space 40 at the front end and the space between the inclined plates 29 on the rear side. Since the wind splitting 51 swings integrally with the swing sorting shelf 3, the wind splitting guide position in the sub-sorting wind path 8 is constant, and a stable separation wind of the sorting wind can be performed regardless of the swing. Can be. Also, the rear end face 52 of the wind split 51
The rear part is inclined downward to the upper surface of the grain 31, and the interval portion 40 receives the leaked grain and guides the grain to flow down to the grain 31 side.
