Description of the Related Art During harvesting work of a combine, cutting of a cereal stalk is temporarily suspended by turning on a headland or the like at an end of a field, and supply of the stalk to a threshing machine is stopped. When cutting must be carried out at a low speed due to cutting off the stalk or lodging of the culm, etc., the amount of thresh that is threshed by the threshing machine and leaks to the sorting section is reduced, and leakage of thresh during normal efficiency is reduced. In the sorting section where the main Karin that blows to the main sorting airway and the auxiliary Karin that blows to the second sorting airway are adjusted and set so that the lower quantity can be sorted properly, the sorting wind becomes too strong and the third mouth ( Grain scattering from the dust outlet) increases. [0003] Therefore, conventionally, when the threshing amount of the threshing machine falls below a certain level, the wind power of the main Karino is automatically reduced, and at the same time, the chaff sheave of the oscillating sorting shelf is hardly leaked. And make adjustments, especially
In addition to the small amount of leaked material, in the second sorting air duct located near the third mouth, it was difficult to control the scattering of grains from the third mouth only by reducing the wind power. [0004] Therefore this invention, when the de-Kokuryo drops below a predetermined level, close the discharge port of the auxiliary winnowing fan to interrupt the selected style in conjunction with the modulation of the main winnowing fan and oscillating sorting shelf, the grain The purpose is to suppress extra-flying.

The structure of a threshing and sorting device of Nbine will be adopted . According to the above construction, the thresh-processed and leaked threshed in the handling room of the threshing machine 4 is roughly sorted by the swinging transfer of the swinging sorting shelf 1 in the sorting room. Then, the coarsely-selected material that has leaked from the chaff sieve 5 is sorted out by the blowing of the main Kara-min 2 in the main selection air passage M, and the coarsest material that does not leak from the chaff-sieve 5 is further selected. In the second sorting air path S, the second thing is sorted by the auxiliary Karin 3 blast. At the time of such a sorting operation, for example, when the cutting of the grain culm is temporarily interrupted by turning on a headland or the like at the end of the field and the supply of the grain culm to the threshing machine 4 is cut off, or the grain culm falls down. When the threshing amount of the threshing machine 4 falls below a certain value, such as when mowing at a low speed, the decrease in threshing efficiency is detected, and first, the rotation of the main thruster 2 is automatically reduced. At the same time as reducing the wind power, the main sorting air passage M is adjusted by adjusting the chaff sheave 5 of the swinging sorting shelf 1 in a direction in which it does not easily leak.

It is supplied to the feed chain 17 of the threshing machine 4. The cereal stalks nipped and transported by the feed chain 17 are handled in a handling room 20.
At the threshing process by the handling cylinder 23 and the processing cylinder 24,
The thresh-processed thresh falls from the handling cylinder receiving net 25 and the processing cylinder receiving net 26, and falls onto the swing sorting shelf 1. Threshing straw waste that does not leak from the handling cylinder receiving net 25 and the processing cylinder receiving net 26 is sent out from the outlets of the receiving nets 25 and 26 and discharged outside the machine by the dust exhaust fan 45. The thresh which has fallen on the swinging sorting shelf 1 is sent to the chaff sheave 5 of the first sorting section 40 by the transport rack section 34, and further, the shelter 38 is leaked from the chaff sheave 5 to the first sorting shelf 39. Sorting shelf 1 while falling to
For the rocking operation of the main sorting wind path M and the sorting wind from the main Karin 2 in the swinging wind selection, and the first grain selected by the swinging wind selection is stored in the receiving trough 49 first and the outside of the machine. Sent out to The thresh that does not leak from the chaff sieve 5
It falls directly from the sieve wire 5a to the second sorting section 43 or falls roughly by the straw rack 37 and falls, and the second sorting shelf 42
In the meantime, rocking operation is performed by the rocking operation of the rocking sorting shelf 1 and the sorting wind from the auxiliary Karin 3 in the second sorting air passage S,
The second item selected by this oscillating wind selection is the second trough 51.
And is returned to the processing cylinder 24. It is to be noted that the sorted dust in the main sorting air passage M and the second sorting air passage S and the dust from the straw rack 37 are discharged from the third opening to the outside of the machine. During the threshing operation, when cutting of the culm is temporarily interrupted by turning on a headland or the like at the end of the field, or when it is necessary to cut the culm at a low speed due to the lodging of the culm, the culm may be used. It is determined whether or not the threshing amount has decreased below a certain amount set by a controller (not shown) based on the detected value of the transport amount of the transported grain culm by the transport amount detection sensor 36 provided in the transport device 18 of the reaper 10. I do. The detection of the transport amount is not limited to this example, and any other method may be used as long as it can be detected. When the determination is less than the predetermined amount, the rotation of the main Karin 2 is reduced by adjusting the Kara Minori pulley 29 by the action of the tension pulley 33 and the transmission belt 31 by the telescopic cylinder 32 under the control of the controller. At the same time as reducing the wind force, the angle of the blades of the chaff sheave 5 by the telescopic cylinder 35 is changed to adjust the direction in which threshing is difficult to leak.
Even if the amount of thresh leaked to zero is reduced, the number of grains scattered outside the machine from the main sorting air path M does not increase. In conjunction with the adjustment in the main sorting air passage M, the discharge port 6 of the auxiliary Karino 3 in the second sorting air passage S is
The discharge port lid 6a is closed by the action of the discharge port opening / closing arm 46 by the telescopic cylinder 47, and the auxiliary
By cutting off the wind force, the second sorting air path S is replaced by the main sorting air path M, so that even if the threshing material leaking to the second sorting section 43 is reduced, the same as the first sorting section 40 is performed. There is no increase in the number of grains flying out of the machine. Also, even if the wind from the auxiliary Karino 3 in the second sorting wind path S is cut off, the sorting can be performed by the wind of the main Karin 2,
In the second sorting section 43, the sorted articles do not stay. It should be noted that the auxiliary Karamin 3 may be stopped from rotating to shut off the wind. The processing cylinder 24, which is arranged in parallel with the handling cylinder 23 in the handling chamber 20, divides its entire length into approximately three equal parts, and has a second processing section in which spiral teeth 52a are wound from the entrance side. 52
The processing body 53 in which a large number of processing teeth 53a are arranged, and the dust processing section 54 in which spiral teeth 54a are wound have different functions. The second processing unit 52 causes the second spiral 50 to reduce the second product transferred to one side of the second receiving trough 51, and the processing body 53 performs threshing by the handling cylinder 23. The object is once taken in and processed, but since this processing alone is insufficient, the processing is returned to the end portion of the handling cylinder 23 again, and the processed material is further returned to the dust processing unit 54 to swing. In order to spread and discharge on the sorting shelf 1,
As shown in FIG. 3, the threshing material is caused to perform a reciprocating processing operation between the handling cylinder 23 and the processing cylinder 24 in an eight-character shape. At the time of the eight-character reciprocating processing operation, as shown in FIG. 4, in order to prevent the processed material taken in from the processing cylinder 24 into the end portion of the processing cylinder 23 from being returned to the processing cylinder 24 immediately without much processing. As shown in FIG. 5, a partition plate 55 having a higher side near the processing cylinder 24 and a lower side near the feed chain 17 is mounted on the handling cylinder receiving net 25 near the end of the handling cylinder 23. In the mowing apparatus 10, the conveying apparatus 18 which conveys the cut culm and delivers it to the feed chain 17 has an ear feeding lug 18a on the upper side and a root feeding chain 18b on the lower side. The root feed chain 18b is provided with a thin plate-shaped holding rod 56 for pressing and holding the transported grain culm with the chain 18b. This holding rod 56 is shown in FIG.
As shown in the figure, the front gripping rod 56a that takes over the transported grain culm from the scraping device 16 and the rear gripping rod 56b that is delivered to the feed chain 17 are divided and rotatably connected to each other. The culm entrance side is formed open in a V-shape, and the cereal culm exit side of the pinching bar 56b is formed along the chain 18b. The holding rod 56 has a front side portion, a connecting portion, and a rear side portion, each of which has a single holding rod 57 pivotally connected to the holding rod 56 via a mounting arm. 57 is inserted through a horizontally long holding holder 58 having a U-shaped cross section, and is provided by being elastically urged by a tension spring 59 provided in the holding holder 58. The insertion hole 58a of the holding rod 57 in the holding holder 58 is formed as shown in FIG. In addition, the size of the holes of the front side and rear side holding rods 57a and 57c is increased as shown by h2 with respect to the size h1 of the hole of the holding rod 57b of the connecting portion, so that the three holding rods 57a are formed. , 57b, and 57c, respectively, can reduce the tension and the like caused by prying between the holding rods 57a, 57b, and 57c, and can reduce the left and right play of the holding rod 56. Further, the tension of the tension springs 59a and 59c on the front side and the rear side is made weaker than the tension of the tension spring 59b of the connecting part among the tension springs 59 in the holding holder 58, whereby It is possible to smoothly take in the beginning of clamping of the cereal culm in the front of the holding rod 56a, and to prevent the buckling due to strong pressing of the small culm at the end of the conveyance of the cereal culm in the rear of the holding rod 56b. A holder stay 58a is fixed to the upper surface of the holding holder 58 at the center in the lateral direction, and the holder stay 58a is arranged so as to bypass the upper pipe 60 from above.
