Next, the operation will be described.

First, the engine is started to prepare for work while driving the rotating corners of the machine body. When the threshing clutch (not shown) is inputted, the threshing switch S is turned ON, and the controller C wins. Then, when the combine is advanced while driving the traveling device 11, the grain stems of the rice fields are harvested by the harvesting device 14 of the front harvesting pretreatment device 16 as the traveling vehicle body 12 advances. It is conveyed upward by the action of (15), is taken over by the pinch conveying apparatus 7, and is supplied to the threshing machine 13. As shown in FIG. Then, the grain stem is sandwiched by the sandwiching portion 7b in which the lower portion is elastically pressed by the conveying chain 7a and the spring means, and the front portion of the grain is supplied to the feeding chamber 1 while being conveyed and rotated. It threshes by the barrel 17.

In this threshing process, the grain stem layer thickness sensor S2 is supplied to the feeding chamber 1 per unit time while measuring the movement between the pinched portions 7b up and down in accordance with the change in the layer thickness of the conveyed grain stem. The amount of grain stem is detected and input to the controller C as detection information.

Then, the processed threshing material is turned by the rotating barrel 17, falls down from the sorting network again under a graining action, falls to the swing sorting shelf 3 of the sorting chamber 2, and undergoes a swing sorting operation.

The to-be-selected object is transferred from the moving shelf 31 to the front of the shelf to reach the chaff receiver 5, and is grained from the separation interval between the plurality of sorting plates 33 constituting the chaff receiver 5. The back falls down and is separated by a long straw back. At this time, the tuyere 18 performs the sorting operation while blowing into the sorting chamber 2 by using the wind rotated while being driven as the sorting wind. The dust is discharged out of the machine by dividing it into the suction and the dust collecting device 29 and reaching the dust discharging port 43 through the front straw-rack 32 of the swing sorting shelf 3.

In this way, the selected object is screened under the joint action of the rocking screening action and the screening wind by the screening wind, and is separated into water 1 (sizing), water 2 and dust, and screening 1 time. The water is collected by dropping onto the first transport spiral 19 and harvested outside the machine, and the second water is bent by the second graining device 22 to the second transport spiral 20 and reduced to the second processing chamber 6. 2, the dust is discharged by the suction and dust removal device 29, and the straw flakes which reach the straw rack 32 are discharged out of the machine through the dust discharge hole 43 in front of the shelf. .

On the other hand, the unprocessed object which is returned by the barrel 17 which remains in the feeding chamber 1 and rotates without falling out from the sorting chamber 2 is sent to the dust treatment chamber 21 at the end of the feeding chamber 1. The dust discharged to the dust treatment chamber 21 is subjected to a treatment action by the dust treatment tank 27 to be discharged from the dust outlet 26 to the sorting chamber 2 and sorted.

By the way, in the threshing operation | movement as mentioned above, the controller C uses the 2nd sensor S 'with which the 2nd process chamber 6 is equipped, and the grain stem layer thickness sensor S2 of the pinching conveying apparatus 7. Selection control is performed based on the detected detection information.

That is, the controller C compares the detection information input from the second sensor S₁ and the grain stem layer thickness sensor S₂ with a sorting criterion previously stored in a microcomputer, while the siber control motor M₁ and the shutter are operated. Selection control is performed by outputting an operation signal to the control motor (M₂).

At that time, the controller C carries the conveyed grain which the flow volume of the 2nd water which flows in the 2nd process chamber 6 supplies to the supply chamber 1 by the detection information input from the above-mentioned sensors S 센서 and S₂. The selection control is performed by monitoring whether or not the stem is within the proportional range based on the reference value compared with the amount of the stem. Then, the controller C basically opens the screening interval to promote the falling down when the chaff sieve 5 has a flow rate of 2 times higher than the proportional range based on the reference value. To control.

On the other hand, although the dust exhaust port shutter 42 normally opens the dust exhaust port 43 and performs threshing sorting operation, conveyance grains supplied to the supply chamber 1 in the following cases, that is, the combine reaches the end of the rice field or the like. When the quantity of the stem becomes extremely small (cutting stop) and the flow rate of water increases relatively twice, the controller C outputs a signal to the shutter control motor M₂ to control the dust exhaust shutter 42 The true mouth 43 can be prevented and 3 losses can be reduced. When the mowing operation is stopped in this way, it is preferable that the chaff sieve 5 also narrows the screening interval.

As described above, according to the present invention, the flow rate of the second water flowing in the second processing chamber 6 is compared with the amount of the conveyed grain stem supplied to the feeding chamber 1 so as to view and control the proportional relation, thereby improving the sorting accuracy. It is characterized by low loss screening.

According to the present invention having the above configuration, it is possible to prevent clogging by conveying a large amount of water twice, as well as to improve the recovery and sorting performance of the grain, to carry out the conveyance efficiently, and to simplify the electric configuration and There is an effect, such as to facilitate the maintenance and management of the dust collector. Hereinafter, the effects of the present invention will be described in more detail. According to the threshing machine of the first invention of the present invention, the processed material handed over from the barrel 50 to the dust treatment tube 55 is the dust treatment tube 55. ), And the second water is treated by the second treatment cylinder 54 having a diameter smaller than that of the exhaust treatment tube 55. That is, by making the circumferential speed of the 2nd process cylinder 54 slower than the circumferential speed of the dust removal process cylinder 55, the grain recovery efficiency from a processed material can be improved, preventing the departure of a grain. In addition, since the exhaust treatment cylinder 55 is comprised with the diameter larger than the 2nd process cylinder 54, the circumferential speed of the exhaust process cylinder 55 becomes faster than the circumferential speed of the process cylinder 54 two times, Compared with the process cylinder 54, the to-be-processed object is conveyed back flexibly in the dust-treatment process cylinder 55 with many straws. In addition, since the circumferential speed of the dust treatment tube 55 is high, the straw is spread, and the grains contained in the straw can be recovered.

Moreover, according to the threshing machine of the 2nd invention of this invention, since the 2nd process cylinder 54 processes the 2nd water while conveying it to the front direction opposite to the conveyance direction of the barrel 50, the 2nd process cylinder 54 The water 2 treated in the step falls to the front of the swing sorting lathe, and when it is reselected on the swing sorting lathe, the sorting process becomes long, so that the sorting with higher precision can be performed.

Further, according to the threshing machine of the third invention of the present invention, the processed material handed over from the barrel 50 to the dust treatment tube 55 is treated by the dust treatment tube 55, and the second water is the dust treatment. It is processed by the process copper 54 twice smaller than the copper 55. That is, by making the circumferential speed of the 2nd process cylinder 54 slower than the circumferential speed of the dust removal process cylinder 55, the grain recovery efficiency from a processed material can be improved, preventing the grain from leaving. In addition, since the exhaust treatment cylinder 55 is comprised with the diameter larger than the 2nd process cylinder 54, the circumferential speed of the exhaust process cylinder 55 becomes faster than the circumferential speed of the process cylinder 54 two times, Compared with the process cylinder 54, the to-be-processed object is conveyed back flexibly in the dust-treatment process cylinder 55 with many straws. In addition, since the circumferential speed of the exhaust treatment tube 55 is high, the straw is spread, and the grains contained in the straw can be recovered. Further, the second treatment cylinder 54 supplies the water twice to the barrel 50. As the water is processed while being conveyed in the forward direction opposite to the conveying direction of the water, the second water treated in the second treatment tank 54 falls to the front of the swing sorting lathe, and the sorting process becomes longer when it is reselected on the swing sorting lathe. More accurate sorting can be performed.

In addition, according to the threshing machine of the 4th invention of this invention, in addition to the effect by the threshing machine of the said 2nd invention of this invention, the structure is made the same by making the diameter of the process copper 54 and the dust-treatment treatment cylinder 55 the same. More streamlined.

Moreover, according to the threshing machine of the 5th invention of this invention, in addition to the effect by the threshing machine of the said 1st-3rd invention of this invention, in conveying 2 times water from the lower side of a threshing machine to 2 process copper 54, Since the shaft center of the 2nd process cylinder 54 is arrange | positioned below the shaft center of the barrel 50, the conveyance distance of 2nd water becomes short and efficient conveyance becomes possible. Moreover, of the 6th invention of this invention, According to the threshing machine, in addition to the effect according to the threshing machine of the said 1st-4th invention of this invention, the 2nd processing cylinder ( 54) and the dust removal processing cylinder 55 do not need to be separated from each other, and can be driven by one electric system, resulting in a simple configuration. Further, according to the thresher of the seventh invention of the present invention, In addition to the effects of the thresher of the first to fourth inventions, Maintenance of the novelty 65 can be easily performed on the side of the threshing machine. [0024] In addition, according to the threshing machine of the eighth invention of the present invention, in addition to the effects of the threshing machine of the first to fourth inventions of the present invention, By detecting water with relatively few straws, high precision detection is possible, and subsequent sorting control also improves precision.
