The threshing apparatus of the other Example 4 comprised as mentioned above has the processing capability of the 2nd processing edge 54a, in order to threshing a large quantity of grain stems (four tanks) supplied compared with the structure of the other Examples 1-3. At the same time, the exhaust transfer plate 64 is further configured, and the process blade 55a of the spiral is mounted on the exhaust treatment cylinder 55 again, and the overall processing capacity is greatly increased.

Next, the operation will be described.

First, the engine is started and ready for work while driving the rotating corners of the machine body. However, if the threshing clutch is operated outside the island, the threshing switch S is turned ON, and the controller C stands. It is. When the combine is advanced while driving the traveling device 11, the grain stem of the pavement is mowed 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 the grain stem conveying apparatus 15, is inherited by the grain stem pinching conveying apparatus 7, and is supplied to the threshing machine 13. As shown in FIG. The grain stem is sandwiched between the lower stem by the sandwich chain 7b which is clamped by the conveying chain 7a and the spring material, and the front portion of the grain stem is supplied to the feeding chamber 1 while being conveyed to the barrel 17 to be rotated. By threshing.

In such a threshing process, the grain stem layer thickness sensor S2 is supplied to the feeding chamber 1 per unit time as it measures that the pinch 7b moves up and down in accordance with the change in the layer thickness between the conveying grains. The amount of grain stem is detected and input to the controller C as detection information.

Then, the processed threshing product is turned by the rotating barrel 17, falls back out of the sorting network while being subjected to a grain processing action, falls to the swing sorting shelf 3 of the sorting chamber 2, and undergoes a swing sorting action.

Then, the object to be sorted is transferred to the front of the shelf on the movable shelf 31 to reach the chaff sheave 5, and the separation is provided between the plurality of sorting plates 33 constituting the chaff sheave 5. Grains etc. fall down at intervals and are separated by long crests. At this time, the tuyere 18 performs a ballooning operation while being blown into the sorting chamber 2 by using the wind that has been rotated while being driven as the sorting wind. The dust is separated into reaching the suction dust collecting device 29 and passing through the front straw rack 32 of the swing sorting bar 3 to the exhaust path 43, respectively, and is discharged out of the machine.

In this way, the blood is screened while undergoing the joint action of the swinging action and the balloon action by the screening wind, and is separated into No. 1 (establishment), No. 2, and dust, and No. 1 transport spiral (19) ) To be collected and dropped out of the machine, the second material is grained by the second graining device 22 into the second spiral 20 and reduced to the second treatment chamber 6 to receive the second treatment action, The dust is discharged by the suction dust collecting device 29, and the rice straw which has reached the straw-rack 32 is discharged out of the machine through the exhaust path 43 in front of the shelf.

On the other hand, the unprocessed object which is turned by the barrel 17 which remains and rotates in the feeding chamber 1 which does not fall down from the sorting chamber 2 is fed to the dust processing 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 collected in the dust separation path 26 in the sorting chamber 2 and sorted.

By the way, in the threshing operation | movement as mentioned above, the controller C is equipped with the No. 2 sensor S 'with which the No. 2 process chamber 6 is equipped, and the grain stem layer thickness sensor S2 of the grain stem pinch 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 thickness sensor S₂ with the sorting criteria stored in the microcomputer in advance, and controls the sheave control motor M₁ and the shutter control. The control signal is output by outputting an operation signal to the motor M2.

At that time, the controller C is a conveying grain stem supplied with the flow rate of the second product flowing into the second processing chamber 6 by the detection information input from the above-described sensors S and S2. The selection control is performed by monitoring whether or not the value is within the proportional range based on the reference value. Then, the controller C basically controls the chaff sieve 5 to open the screening interval to promote the falling down when the flow rate of the second product increases by more than the proportional range by the reference value, and to control the closing to the closing. do.

On the other hand, the exhaust path shutter 42 normally opens the exhaust path 43 and performs the threshing sorting operation. However, in the following cases, that is, the conveying grain stem which the combine reaches the end of the package and supplies to the supply chamber 1; When the amount becomes extremely small (cutting stop) and the flow rate of the second product is relatively high, the controller C outputs a signal to the shutter control motor M2 to control the backflow shutter 42 to control the backflow path. By blocking (43), the third loss can be reduced. When the mowing operation is stopped in this way, it is preferable that the chaff sieve 5 also narrows the selection interval, and so controlled.

As described above, the present invention compares and controls the flow rate of the second product flowing into the second processing chamber 6 with the amount of the conveying grain stem supplied to the supply chamber 1, so that the degree of sorting is improved and the loss is small. There is a characteristic that can be screened.

Since this invention is comprised as mentioned above, in invention of Claim 1, since the distance which moves a 2nd material upward of a threshing machine becomes short, a 2nd material can be easily conveyed to the 2nd process cylinder 54. Therefore, even if the quantity of the to-be-processed object in a threshing machine becomes large, since 2nd thing can be conveyed efficiently, clogging etc. can be prevented. In particular, the length of the second grain-curing device 22 is shortened, and clogging can be prevented even if the number 2 material is conveyed in large quantities.

In the invention described in claim 2, even if either of the second treatment tank 54 or the dust treatment tube 55 is blocked, in the case of the stain of the other treatment cylinder (the second treatment cylinder 54), the dust is The driving force for rotating the processing cylinder 55 is forcibly rotated, thereby eliminating the blocked state.

In the invention according to Claim 3, the processing capacity is inevitably improved since the second processing cavity 54 is adapted to the diameter of the dust-treating treatment cylinder 55 with the larger processing capacity.

In the inventions of claims 4, 5 and 6, since the dust treatment tube 55 forcibly takes in and processes the object from the supply chamber 50, clogging can be prevented.

In the invention according to claim 7, since there is nothing hindering the to-be-processed object discharged from the dust-treatment treatment vessel 55, the to-be-processed substance is efficiently discharged from the dust-treatment treatment vessel 55, and thus clogging can be prevented. .
