EXAMPLES Examples of the present invention will be described below. A cutting unit 2 is provided at a front portion of a vehicle body having a traveling crawler 1 so as to be able to move up and down, and a thresher 3 for threshing the grain culms cut by the cutting unit 2 is mounted on the rear side. The mowing unit 2 lifts and conveys the raising device 2a for raising four-row grain culms, the reaping device 2b for reaping the grain culms after the raising, and the grain culms after mowing, and the feed chain of the thresher 3. It is composed of a grain culm conveying device 2c and the like to be delivered to 5 is an operation box, 6 is a driver's seat, 7 is a Glen tank, 8 is a reaping clutch lever, and 9 is a threshing clutch lever.

The combine constructed as described above is constructed so as to control the traveling speed (vehicle speed) of the vehicle body according to the number of cutting lines of the grain culms to be cut by the cutting unit 2.
Reference numeral 10 is a No. 1 grain lifting device that lifts and conveys the No. 1 grain that has been threshed and selected by the threshing machine 3, and discharges and puts it into the Glen tank 7. The flow rate of grain is detected at an outlet 11 at the upper end of the grain elevator. A detection device (flow rate detection sensor-12) is provided.

Then, while the flow rate of the grain is being measured by the flow rate detecting sensor-12, a constant A ₁ calculated by the microcomputer 13 by the flow rate of the grain / (vehicle speed × number of cutting lines) and the setter 15 are used. The set value A ₂ that has been set is compared and calculated, and A ₂ > A
_When it becomes ₁ , that is, when the flow rate becomes abnormally small, the alarm 14 is generated. However,
The set value A _{2 in} this case may be automatically stored in the microcomputer when actual cutting is performed during normal use. In addition, the grain culm sensor and the switch of the threshing clutch are installed as conditions for the beginning of cutting.

The threshing machine 3 has the following construction. That is, the handling barrel 17 is internally mounted on the handling room 16,
A receiving net (crimp net 18) is stretched along the lower half of the handling room. Reference numeral 19 indicates a processing cylinder, and 20 indicates a dust outlet. Reference numeral 21 is a handle barrel cover, and 22 is a discharge straw conveying chain. The handling body cover -21 is configured to be capable of swinging and opening and closing around the fulcrum P, and the discharged straw conveying chain 22 is configured to swing and open and close integrally with the handling body cover -21.

A gas damper-2 is used for opening / closing the handle cover 21.
3 and 24 are used, but the dampers 23 and 24 are
A damper with a long stroke (l
₁<L₂) And the fulcrum position Q on the machine side₁, Q₂To
Front side Q₁Q behind ₂Handle body cover side fulcrum P position
Is set to a position far from. Both dampers at this time
-The same thrust is used.

In order to open the handling barrel cover integrally with the exhaust straw conveying chain, it is necessary to support it with a gas damper having a large thrust, but when closing it, it is difficult to close it because the thrust of the damper is too large. May be. In such a case, when the damper having the above-mentioned configuration is used, when the handle cylinder cover is opened, it is supported by the front and rear dampers 23 and 24 (same thrust force), so that the handle cylinder cover does not lower. When closing the handling barrel cover, when the handling barrel cover comes close to the front, the front damper angle θ ₁ becomes smaller than the rear damper angle θ ₂ and the thrust for lifting the handling barrel cover is exerted. Since it disappears, the handle barrel cover can be easily closed.

[0012] Below the handling chamber 16, the threshing-treated products leaking from the receiving net 18 and the dust-treated products from the dust outlet 20 are received and sieving is performed while swinging and transferring to the rear side in the axial direction of the handling cylinder. An oscillating sorting device 25 is provided. Swing sorting device 25
Is a primary Glen pan 26, and a chaff sheave 27 and a straw rack 28 that are continuous behind the primary Glen pan 26.

Then, the processed material which has leaked from the receiving net 18 and has passed through the front side of the primary gren pan 26 and the chaff sheave 27 is oscillated and transferred by the secondary gren pan 29 to the rear gren sieve 30. After that, while being sifted and sorted by the Glensieve 30 and being wind-selected by the sorting wind from the Karato 31, it is rocked and transferred to the rear side, and is dropped and discharged from the rear end.

On the other hand, the dust outlet 20 of the handling chamber 16 (processing cylinder 19
Waste products discharged from the chamber (including dust discharged from the dust outlet of the chamber) are directly received in the rear part of the chaff sheave 27, and are transferred to the rear while swinging and sorting. The air is discharged from the end of the straw rack 28 together with the sorting wind to the outside of the machine, and the suspended dust is sucked and discharged by the suction dust discharge device 32. Reference numeral 33 is a diffusion helix for diffusing the dust-removed product.

A No. 1 trough 34 and No. 1 conveyor 35 and a No. 2 trough 36 and No. 2 conveyor 37 are provided at the bottom of the sorting chamber. The first trough 34 communicates with the first grain lifting device 10. In the Karato 31, the blade 38 is divided into three in the direction of the Karato shaft 39, and left and right side fans 38L and 38R are formed.
And a center fan 38C at the center, and both side fans 38L and 38R and a center.
The fan 38C is constructed so as to rotate in the directions opposite to each other in the arrow (a) direction and the (b) direction, and at the same time,
The upper and lower two-stage structure is provided so that the outlet from the single is formed by the lower primary air passage F ₁ and the upper secondary air passage F ₂ .

It is configured to pass through between the number conveyor 35 and blow toward the suction and dust removing device 32 at the upper rear side. The upper secondary air passage F ₂ is configured so that the air from the center fan 38C passes through below the chaff sheave 27 toward the suction / dust removal device 32 on the rear side. That is, chaff sheave 2
It is configured so as to pass through between the 7 and the Glensive 30 and blow upward in the rear direction.

Both side fans 38L, 38R
The center fan 38C and the center fan 38C are switched to opposite directions so that the air outlets of both side fans 38L and 38R are set to the upper side (secondary air passage F ₂ ) and the center fan 38C is set to the lower side (1 It may be changed so as to be the next air passage F ₁ ), or the switching may be freely changed. In the primary air passage F ₁ from both side fans 38L, 38R, the main selection air is sent, but it passes through between the Glensieve 30 and the No. 1 conveyor 35 and blows upward toward the rear. -It is possible to efficiently and satisfactorily select the most of the grains that leak from the bush 30.

Secondary air passage F ₂ from the center fan 38C
In this case, the selection wind passes through between the chaff sheave 27 and the Glensieve 30 and blows upward toward the rear, and a part of the wind blows upward from between the fins of the chaff sieve 27. Preliminary wind selection of the spillage that falls onto the rocking sorting device 25 can be eliminated to eliminate retention on the rocking sorting device 25.
