Reference numeral 44 is a Karako rotation sensor for detecting the number of rotations of the blast Kara7, 45 is a sheave angle sensor composed of a position detection sensor or the like, and 46 is a guide angle sensor composed of a position detection sensor or the like. That is,
When the rotation speed of the blower sardines 7 becomes faster, the CPU 43 operates the discharge side angle adjusting motor 35 to change the angle to a substantially vertical state. When the number of rotations of the blast Kara 7 becomes faster, the wind strongly flows toward the discharge side and blows up upward at the Straw rack 14 as it is. No.) is discharged out of the machine together with the straw waste, and a loss occurs in the recovery of the third product, but when the discharge side angle adjustment motor 35 is set to the standing state,
The wind toward the Straw rack 14 is guided upward by the discharge-side sheave 28, so that not only the sorting precision in the discharge-side sheave 28 is improved, but also the wind force and the air volume of the sorting wind in the Straw rack 14 become appropriate and the third sorting precision is obtained. Also improves. Reference numeral 47 is a Karatsuro rotation changing motor for changing the number of rotations of the blower Karako 7 and operates the transmission constituted by the split pulley.

The lower end of the guide guide 37 is rotated upward so that the supply side becomes lower and the discharge side becomes higher as the number of rotations of the blower sardine 7 increases, so that the guide guide 37 rotates upward.

The supply-side sheave 27, the discharge-side sheave 28, and the guide guide 37 may have controls other than those described above.

[0011]

[Operation] Next, the operation will be described. When the grain culms are supplied to the threshing chamber 2, the rotating handling drum 3 in the threshing chamber 2 threshes the grains, and the threshed grains are transferred from the handling net 4 to the transfer rack 11 of the swing selection device 10.
It drops to the top and is transferred by the transfer protrusions 12 of the transfer shelf 11 to reach the wind selection chamber 9, and in the sheave 13 of the rocking and sorting device 10, the rocking sheave 13 and the air blown from the air blower sardine 7 produce straw waste. The grains are separated, fall from the gap of the sheave 13, drop into the trough 16 first, and are taken out of the machine first from the conveyor 17. Straws and the like do not fall from the gap between the sheaves 13, so that the rocking / sorting device 10 rocks and the blowing fan 7
Is moved to the discharge side by the blowing of
Dust and straw dust are sucked and removed by the suction / dust fan 24, and the straw dust that is not sucked by the suction / dust fan 24 reaches the straw rack 14, and the straw dust that does not drop from the straw rack 14 is discharged from the outside discharge port 23. The second cutting trough 18 catches the cuttings and branch adhering particles discharged from the machine by the swing of the straw rack 14, and although not shown in the drawing, the threshing chamber 2 or the processing chamber is operated by the second picking device. And reprocessed.

In addition, the second trough 18 also receives the cuttings of the spikes, the branches adhering particles and the like which do not fall from the sieve 13 but from the sieve net 20. In this case, since the supply-side sheave 27 located above the supply-side most gutter 16 of the sheaves 13 can change the angle between the substantially vertical standing position and the inclined position,
When the load is small, standing upright blows up the blast from the blast Karano 7 to separate the straw debris from the grain, and the gap between the fins 29 of the supply-side sheave 27 becomes large. Grains are likely to fall, sorting efficiency is improved, and sorting is prioritized (note that the supply-side sheave 27 may be tilted to weaken the blast of the blast sardine 7). On the other hand, when the load becomes large, if the supply-side sheave 27 is tilted, the air blow direction of the blower Kara-no-Miru 7 is directed to the discharge side, so that the one on the supply-side sheave 27 is quickly transferred to prevent clogging. .

The sheave 13 is composed of the supply-side sheave 27 and the discharge-side sheave 28 located substantially above the second trough 18, and the supply-side sheave 27 has fins 29 of the same length. Although the exhaust sheaves 28 are arranged side by side, the fins 29 on the supply sheave 27 side are short and the long fins 29 are arranged downward as they reach the straw rack 14. Sheave 28
The amount of wind air blown up by the straw rack 14 toward the straw rack 14 is adjusted appropriately, and the grains (third object such as the cuttings of the spikes and the particles attached to the branch branches) on the straw rack 14 are not discharged from the out-of-machine discharge port 23. Drop the second gutter 18 and drop the second gutter 1
Increase the reduction of grain to 8. Also, the discharge side sheave 28
Since the angle can be adjusted independently of the supply-side sheave 27, the supply-side sheave 27 is erected when the rotation speed of the blower sardines 7 is normal, but the discharge-side sheave 28 is tilted to the straw rack 14. Since an appropriate amount of wind air is sent and the blast of the air blower Karamoru 7 is not strong, sufficient selection can be performed even if the discharge-side sheave 28 is inclined.

Further, if the rotation speed of the blasting sardine 7 becomes faster,
Although the supply-side sheave 27 is inclined, the discharge-side sheave 28 can be controlled by the discharge-side angle adjusting motor 35 so as to be in a substantially vertical state. However, when the discharge-side sheave 28 is steeply inclined, the gap between the fins 29 becomes large, and the wind blows upward, so that the separation of straw debris and the grain becomes good, and the efficiently separated grain becomes Not only is it dropped and collected on the second gutter 18, the sorting accuracy is improved, but the wind blows upward at the discharge-side sheave 28, so that even if the air blow from the air blow sardine 7 is strengthened, the straw rack Properly maintain the wind volume toward 14 and drop the grains (third item such as cuttings and branches attached grains) on the Straw rack 14 to the No. 2 trough 18, and to the No. 2 trough 18. Highly accurate sorting can be performed by increasing the reduction of grain and preventing the increase of No. 3 loss. Therefore, the angles of the supply-side sheave 27 and the discharge-side sheave 28 can be adjusted independently, so that the air blowing direction can be appropriately switched, and accurate and efficient air selection can be performed.

A guide guide 37 is provided between the discharge-side sheave 28 and the suction dust-exhaust fan 24. The guide guide 37 is formed by a parallel flat plate member, and is in a substantially vertical state when the load is small. Since it is located, the discharge side sheave 28
Further, the wind toward the suction / dust fan 24 is prevented from being directed toward the outside discharge port 23, and the sorting in the straw rack 14 is improved. That is, when the wind blows strongly over the straw rack 14 toward the outboard discharge port 23, the grains as well as the straw waste are also discharged out of the machine, but this is prevented. Further, since the guide guide 37 rotates the lower end of the guide guide 37 upwards so that the supply side becomes lower and the slope becomes higher toward the discharge side when the rotation speed of the blower sardines 7 becomes faster, the guide guide 37 is rotated by the discharge side sheave 28. The suctioned dust exhaust fan 24 guides the blown air to be surely sucked to enhance the dust emission effect and improve the overall sorting performance. Further, since the discharge side sheave 28 is located above the second gutter 18, the stroll rack 1
Grains can be sorted not only by the No. 4 but also by the discharge side sheave 28, and the No. 3 loss is prevented from increasing by increasing the No. 3 grain collected in the No. 2 gutter 18.

Further, a suction / dust fan 24 is provided above the discharge sheave 28, and the suction dust fan 24 sucks the upward wind by the discharge sheave 28, so that the suction dust fan 24 from the discharge sheave 28. The selection wind is blown in a wide space between the 24 to improve the selection, and the suction dust removal fan 24
Since it does not need to rotate quickly, the loss of sucking and removing grains is eliminated and the sorting efficiency is improved. Particularly, since the guide guide 37 is interlocked with the discharge-side sheave 28 and the guide guide 37 is rotated upward when the discharge-side sheave 28 is erected, the sorting wind is further sucked from the discharge-side sheave 28 to the suction / dust fan 24. Since the blow does not blow strongly on the discharge side toward the discharge side, the discharge side sheave 28 and the straw rack 14 can be sorted well, and sorting can be performed ideally. Then, the supply side sheave 27 and the discharge side sheave 2
When the angle adjusting motors 33 and 35 are energized by the control of the CPU 43, the arm 34 rotates to move the connecting rod 32, the connecting rod 32 moves to rotate the arm 31, and the arm 31 rotates. The mounting shaft 30 is rotated to rotate the fin 29.

Further, the mounting shaft 38 of the guide guide 37 is rotated by the guide angle adjusting motor 42 to change and adjust the angle. In this case, the supply-side sheave 27, the discharge-side sheave 28 and the guide guide 37 of the sheave 13 are angularly adjusted by the motors 33, 35 and 42, respectively.
CPUs 3, 35, and 42 detect that the rotation speed of the blasting sardines 7 has been increased by the sardine rotation sensor 44.
43 operates these to change the angle. Therefore, the automatic control of the CPU 43 simplifies the operation and improves the work efficiency. Further, in the embodiment shown in FIG. 7, the CPU 43 determines the load based on a part or all of the data obtained by various sensors, and the rotation of the handling cylinder 3, the rotation of the blower sardines 7, and the rocking of the rocking / sorting device 10. Moving, supply side sheave 2
7. Since the angles of the discharge-side sheave 28 are automatically controlled, work is performed in an optimum state. Further, since it is automatically controlled, the operation is facilitated and the operability is improved.

As a result, the accuracy of sorting is improved, and even if the air blow from the air blow Kara Minoh 7 is strengthened, the amount of wind flow toward the Straw rack 14 is appropriately maintained. Further, according to the present invention, since the supply-side sheave 27 and the discharge-side sheave 28 are threshing devices that are configured to be independently adjustable in angle, the discharge-side sheave 28 is independent of the supply-side sheave 27. The angle can be adjusted, and particularly, when the rotation speed of the blasting sardine lees 7 is increased, the supply-side sheave 27 is inclined to strengthen the conveying force by the blast to prevent clogging, and the discharge-side sheave 28 is steeply inclined. The sorting accuracy can be improved and the overall sorting can be improved. Further, according to the present invention, when the load on the threshing device is large, the discharge-side sheave 2 is configured such that the discharge-side sheave 28 has a steep inclination angle in the inclined state in which the supply side is low and the discharge side is high.

Since it is a threshing device that is connected in a related manner, the sorting wind is
8 towards the suction / dust fan 24,
4 does not blow strongly to the discharge side, the discharge side sheave 28 and the straw rack 14 can be sorted well, and the sorting can be performed ideally. The present invention also includes a threshing chamber 2 provided with a handling barrel 3 and a wind-selecting chamber 9 for wind-selecting grains, straw waste, and the like by blowing air from a blast air blower 7 provided below the threshing chamber 2.
