DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings of a combine. 1 is a body frame of the combine, 2 is a traveling device provided below the body frame 1, and 3 is a body frame 1.
Is a harvesting unit provided on the front side of the threshing device 3, 5 is a Glen tank 5 provided on a side of the threshing device 3, and 6 is a control unit provided on the front side of the Glen tank 5. .
Thus, the grain tank 5 is connected to the upper part of a grain-lifting device 7 for grain-graining the grain taken out of the machine from the threshing device 3, and the grain in the grain tank 5 is connected to the bottom of the grain tank 5. A grain conveying device 8 for discharging is provided, and a lower end of a discharging and frying device 9 for frying the conveyed grains is connected to an end of the grain conveying device 8. Install 10 bases. The discharge auger 10 is configured such that its tip is vertically movable and pivotable. A shutter 12 is provided above the spiral transport body 11 of the grain transport device 8 over the entire length of the spiral transport body 11 so as to be vertically movable, and a gap T between the spiral transport body 11 and the shutter 12 can be adjusted. To be configured. The shutter 12 is formed in a chevron shape whose center is high when viewed from the axial center direction of the spiral transporting body 11. An arm 13 is attached to an end of the shutter 12, and a sector gear 14 provided on the arm 13 is rotated by an actuator 15. , The shutter 12 is moved up and down with respect to the spiral conveyance body 11,
2 is moved upward to increase the gap T, the Glen tank 5
When the transport amount in the discharge path from the discharge auger 10 to the discharge auger 10 is increased and the gap T is narrowed by moving the shutter 12 down, the transport amount in the discharge path is reduced.

In this case, the shutter 12 is vertically controlled by the moisture content of the grains in the Glen tank 5. As an example, a near-infrared moisture meter 18 capable of measuring moisture is provided in the Glen tank 5, and when the moisture value is high by the near-infrared moisture meter 18, the shutter 12 is moved down, and when the moisture value is low, the shutter 12 is moved. Move 12 upward. The near-infrared moisture meter 18 may have any configuration, but as an example,
A light source irradiates the grain with light, and only a near infrared ray of 1.45 micrometers, which has a high rate of being absorbed by moisture among reflected light from the grain, is transmitted through means such as a filter.
The transmitted wave is received by the light receiving element for measuring moisture, and the moisture value of the grain is measured. In addition, a threshing chamber 21 is provided at the upper part of the threshing device 3 and has a handle drum 20 mounted thereon. The lower part of the handle cylinder 20 is mainly surrounded by a handle net 22, and below the handle net 22, Casing 24 is provided,
Numeral 3 blows air toward the axial end side (rear side) of the handling cylinder 20. From the lower part of the threshing chamber 21 to the rear, an air selecting chamber 25 is formed, which can select kernels and foreign matter by the blowing of the blowing fan 23.

In the wind selection chamber 25, there is provided a swing sorting shelf 26 which swings back and forth in the blowing direction of the blowing fan 23. The swing sorting shelf 26 has a transfer shelf 28 having a transfer protrusion 27 arranged at the start end thereof in the swinging direction facing the upper side of the casing 24, and transfers the fallen object dropped on the transfer shelf 28 to the wind sorting chamber 25. Thus, the space for mounting the swing sorting shelf 26 and the casing 24 is effectively arranged. The swing sorting shelf 26 is provided with a sheave 30 for sorting grains and foreign matter following the transfer shelf 28, and a straw rack 31 capable of transferring straw waste is provided on the end (discharge) side of the sheave 30. . A first conveyor 32 is provided below the sheave 30, and a second conveyor 33 is provided on the terminal side of the wind selection chamber 25 from the first conveyor 32.
Reference numeral 34 denotes a suction / discharge fan provided at the end of the wind selection chamber 25 for sucking dust and straw chips. Then, the swing sorting shelf 2
6 is provided with a drying blowing means S for drying the grains and the like in the swing sorting shelf 26. The drying blowing means S is a swing sorting shelf 26.
If it is provided at least in the portion of the transfer shelf 28, the subsequent sorting operation becomes good. The drying air blowing means S is configured by providing an air nozzle 35 on a part or all of the swing sorting shelf 26, and the air nozzle 35 is provided at a predetermined interval on a blower tube 36 provided around the swing sorting shelf 26. A plurality of blowers (not shown) provided at predetermined positions are connected to the blower tubes 36. Further, it is preferable that the air nozzle 35 is configured to blow (spray) toward the lower side in the swinging direction of the swing sorting shelf 26 because a conveying action can also be expected.

That is, in the embodiment, the blower tube 36 is arranged around the swing sorting shelf 26 so that the sheave 30 and the straw rack 31 are also blown from the air nozzle 35, and the front side of the swing sorting shelf 26. The air nozzle 35 of the blower tube 36 provided at the bottom is opened toward the rear side parallel to the swing direction so as to blow (blast) toward the end side (rear side), and the swing sorting shelf 2 is opened.
The air nozzles 35 of the blower tubes 36 provided on the left and right sides of 6 are opened obliquely rearward, and are configured to blow (spray) toward the left and right central sides of the swing sorting shelf 26. The blower that blows to the air nozzle 35 blows when the moisture value of the grains in the threshing chamber 21 becomes higher than a predetermined value, thereby preventing scattering of dust and the like and drying of grains having a high moisture value. It is preferable to achieve both. The moisture value in this case is stored in the funnel 37 at the entrance of the threshing chamber 21 by the near-infrared moisture meter 18.
Is provided, and when the water value of the grain and the grain culm is measured, a reasonable configuration is obtained, which is preferable. Thus, the swing sorting shelf 26 increases the swing amplitude stroke and the number of swings when the moisture value of the grain and the culm is high, and swings the swing amplitude width and the swing when the moisture value is low. When the number is small, stable sorting accuracy is obtained, which is preferable.

Upper and lower rollers 50 are provided on both left and right sides of the swinging sorting shelf 26, and upper portions of upper guides 51 having a channel shape are fitted to the upper rollers 50, respectively. Fix the collar 52 and fix the collar 5
2 is rotatably inserted only through a support shaft 53 provided in a fixed portion of the threshing device 3, and the end of one or a plurality of cylinders 54 is attached to the end of the swing sorting shelf 26,
The base of the cylinder 54 is attached to an attachment shaft 55, and the cylinder 5
4 supports the end of the swing sorting shelf 26. Also, on the left and right sides of the starting end of the swing sorting shelf 26, the starting end fitting members 56 are provided.
The starting end side fitting member 56 is fitted to a guide support member 57 provided on a fixed portion on the starting end side of the threshing device 3 to swingably support the starting end side of the swing sorting shelf 26. An upper portion of a lower guide 58 having a channel shape different from that of the upper guide 51 is fixed to one of the left and right collars 52, and a lower roller 59 is fitted to a lower portion of the lower guide 58. The lower roller 59 is attached to the crank arm 60, and the crank shaft 61 of the crank arm 60 is mounted on a fixed part of the threshing device 3,
A pulley 6 for transmitting the rotation of the engine is provided on the crankshaft 61.
2 is provided.

In the above case, when the cylinder 54 is expanded and contracted, the upper roller 50 moves far and near with respect to the support shaft 53. Therefore, when the cylinder 54 is extended and the upper roller 50 is moved upward, the swing stroke becomes large and Since the stroke speed increases, the cylinder 54 is extended when the moisture value is high, and the cylinder 54 is contracted when the moisture value is low to reduce the swing stroke to a small stroke speed. Further, when the cylinder 54 is expanded and contracted, the end of the swing sorting shelf 26 moves up and down around the start end side fitting member 56, so that the height of the end side of the swing sorting shelf 26 is changed up and down, The angle can be freely changed, and when the moisture value is low, the height is increased. When the moisture value is high, the height is reduced to speed up the transfer and reduce the load, which is preferable. If the height of the end of the sorting shelf 26 is reduced, the tilt angle is appropriate, but the swing stroke becomes small. Therefore, it is preferable to compensate by increasing the number of rotations transmitted to the pulley 62. Thus, the first conveyor 32 and the second conveyor 33 are configured to change the rotation according to the moisture value, and perform rotation control based on the moisture value. As an example, the second conveyor 33 raises and lowers the water content and the rotation speed in a proportional relationship, increases the rotation speed when the water content is high, and decreases the rotation speed when the water content is low. When the moisture value is low, the wheat is rotated at a high speed but the rice is low. When the moisture value is intermediate, the rice and wheat are all rotated at a high speed. In each case, the rotation is controlled to be low.

Thus, the handling cylinder 20 is configured to change the rotation according to the moisture value, and performs rotation control based on the moisture value. As an example, when the moisture value is low, wheat is set to high rotation, but the rice is low.When the moisture value is intermediate, all the rice and wheat are set to high rotation, and when the moisture value is higher than a predetermined value, both rice and wheat are set. Control the rotation low. Further, the air blower 23 is configured to change the rotation according to the moisture value.
Increases or decreases the water content and the number of rotations in a proportional relationship, increases the number of rotations when the moisture value is high, and decreases the number of rotations when the water value is low. Change the rotation. In this case, when the water value of the cereal culm becomes a specific value due to, for example, water droplets adhering to the cereal culm, the rotation of the handling drum 20 is low regardless of the water value of the grain, and
3 controls so that it may become the maximum rotation. Above the transfer shelf 28 of the swing sorting shelf 26, a cleaning body 40 for cleaning straw dust, dust, mud, and the like is provided. The cleaning body 40 is provided in parallel with the swinging direction of the swing sorting shelf 26, is provided so as to reciprocate in a direction crossing the swinging direction, and slides on the upper surface of the transfer shelf 28 to contact with the straw debris, dust, mud, etc. It removes falling objects.

In the embodiment, the cleaning body 40 is constituted by a rotating brush body 41, and a base 44 of a brush rotating shaft 42 at the center of the rotating brush body 41 is provided on a front side of a front plate 43 of the threshing device 3. , A rotary motor 45 for rotating the brush rotary shaft 42 is provided on the bearing body 44, and a screw shaft 46 is screwed into the rotary motor 45.
7, so that the bearing body 44 reciprocates right and left with respect to the screw shaft 46 by forward and reverse rotation of the movement motor 47. The bearing body 44 is provided with a direction changing switch 48 at both ends of the screw shaft 46, and when the bearing body 44 comes into contact with any of the switches 48,
The rotating brush body 41 is reciprocated by reversing the moving motor 47. Further, when the rotating brush body 41 is spirally implanted in the brush rotating shaft 42, the rotating brush body 41 acts so as to convey an object on the transfer shelf 28 to the terminal end side when rotated, which is preferable.

[0014]

Next, the operation will be described. When the airframe is run by the traveling device 2, the culm is cut by the cutting unit 4, and the cut culm is supplied to the threshing room 21, threshed by the rotating handling cylinder 20 in the threshing room 21, and is cut by the handling net 22. The fallen object falls onto the transfer shelf 28 of the swing sorting shelf 26, is transferred by the transfer protrusion of the transfer shelf 28, and reaches the sheave 30. On the sheave 30, the swaying sheave 30 and the air blown by the blower Karino 23 separate the straw dust and the grain, and the grain and a little straw dust fall from the gap between the sheaves 30 and fall from the gap between the sheaves 30. The non-falling straw waste and the like move to the discharge side by the swing of the swing sorting shelf 26 and the blowing of the blower Karin 23, and the wind sorting chamber 25.
At the end of the straw, the dust and the straw dust are sucked out by the suction / dust fan 34, and the straw dust not sucked by the suction / dust fan 34 reaches the straw rack 31 and the straw rack 3
Straw debris that does not fall from 1 is discharged further out of the machine. The second product collected by the second conveyor 33 is returned to the threshing room 21 or the second processing room (not shown) for processing.
The air is again supplied to the air selection chamber 25 and subjected to the air selection processing.

The grains that have been sorted in the wind separation chamber 25 and dropped on the first conveyor 32 are transported by the first conveyor 32 to the grain-lifting device 7, and the grain-harvesting device 7 stores the grains in the Glen tank 5. And then temporarily store it. When a predetermined amount of grains accumulates in the Glen tank 5, the grain transport device 8 is operated, and the grains transported by the grain transport device 8 are fried by the discharge / frying device 9, and then discharged out of the machine by the discharge auger 10. Let it drain. A shutter 12 is provided above the spiral transporting body 11 of the grain transporting device 8 so as to be vertically movable, and a gap T between the spiral transporting body 11 and the shutter 12 is configured to be adjustable. Changes the gap T by raising or lowering according to the moisture content of the grains in the Glen tank 5, controlling the transport amount in the discharge path from the Glen tank 5 to the discharge auger 10 to an appropriate amount,
Prevent clogging. That is, when the moisture value is high by the near-infrared moisture meter 18 provided in the Glen tank 5 and capable of measuring moisture, the shutter 12 is moved downward, whereby the gap T between the spiral conveyance body 11 and the shutter 12 is narrowed and the shutter 12 is discharged. The conveyance amount in the path is reduced to prevent the occurrence of clogging, and when the moisture value is low, the shutter 12 is moved upward as compared with the case where the moisture value is high, so that the gap T between the spiral conveyance body 11 and the shutter 12 is widened and the discharge path is reduced. Increase the inside transport amount.

The vertical configuration of the shutter 12 is arbitrary, but the shutter 12 is formed in a chevron shape whose center is high when viewed from the axial direction of the spiral carrier 11, and an arm 13 is attached to an end of the shutter 12. Sector gear 1 provided on arm 13
Since the actuator 4 is configured to be rotated by the actuator 15, when the actuator 15 is operated, the sector gear 14 rotates the arm 13, and the arm 13 moves the shutter 12 up and down with respect to the spiral conveyance body 11. However, since a plurality of air nozzles 35 are provided at least around the transfer shelf 28 of the swing sorting shelf 26, when air is blown from the air nozzle 35 to the grains on the transfer shelf 28, the moisture value of the grains is reduced. Lower and improve the sorting. Since the air nozzle 35 is formed in the blower pipe 36 provided around the transfer shelf 28 of the swing sorting shelf 26, the air nozzle 35 can be blown on the transfer shelf 28 with a simple configuration, and the grains can be dried. Further, when the blower that blows air to the air nozzle 35 is configured to blow when the moisture value of the grain in the threshing chamber 21 becomes higher than a predetermined value, the moisture value of the grain is set to an optimum state, and the sorting is improved. .

When the water content of the grain and the culm is high, the swing sorting shelf 26 increases the swing amplitude and the number of swings. I do.
When the moisture value is low, it is preferable to make the width of the swing amplitude and the number of swings small, because stable sorting accuracy can be obtained. That is, when the cylinder 54 is expanded and contracted,
Moves toward and away from the support shaft 53, and the turning radius of the upper roller 50 changes in length. Therefore, when the cylinder 54 is extended and the upper roller 50 is moved upward, the swing stroke is large and the stroke speed is high. Therefore, when the moisture value is high, the cylinder 54 is extended, and when the moisture value is low,
The swing stroke can be reduced by reducing the cylinder 54 to reduce the small stroke speed, which is preferable. Thus, cylinder 5
By expanding and contracting 4, the end of the swing sorting shelf 26 moves up and down around the center of the starting end fitting member 56. Therefore, the height of the end of the swing sorting shelf 26 can be changed up and down, and the moisture value is high. In some cases, the transfer speed is increased by lowering the height and the inclination of the swing sorting shelf 26 is reduced to reduce the sorting load, and when the moisture value is low, the height is increased to increase the swing sorting shelf 26. The steepness of the steepness is reduced and the transfer speed is reduced to improve the sorting accuracy.

In this case, if the height at the end side of the swing sorting shelf 26 is reduced, the tilt angle is appropriate, but the swing stroke becomes small. Therefore, if the rotation speed transmitted to the pulley 62 is increased, it is compensated. Thus, the tilting of the swing sorting shelf 26 and the speed of the swing stroke are compatible, and sorting can be performed. Thus, the rotation of the engine is transmitted to the pulley 62, and the pulley 62 rotates the crankshaft 61. The lower roller 59 provided on the crank arm 60 of the crankshaft 61 rotates about the crankshaft 61, and the lower roller 59 The lower guide 58 rotates about the support shaft 53 by the rotation of, so that the circular motion is changed to a reciprocating motion. When the lower guide 58 rotates, the collar 52 rotates forward and reverse, and the forward and reverse rotation of the collar 52 causes The upper guide 51 rotates back and forth, and the swing sorting shelf 26 swings in the front-rear direction via the upper roller 50 fitted to the upper guide 51. Therefore, the upper rollers 50 on both right and left sides of the swing sorting shelf 26 are merely fitted to the upper guide 51. Even if the end of the swing sorting shelf 26 is moved up and down by the cylinder 54, the rotation transmission mechanism is not affected. Without using a simple configuration, the rotation transmission mechanism, the swing stroke changing mechanism, and the swing inclination changing mechanism can be used in common, resulting in a rational configuration and low cost.

Thus, the first conveyor 32 and the second conveyor 33 convey the water in an optimum state according to the water content because the second conveyor 33 raises and lowers the water content and the rotation speed in a proportional relationship. That is, when the second conveyor 33 has a high moisture value, the number of rotations is increased, so that the conveying force is increased to suppress the occurrence of clogging. In addition, when the moisture value is low, the number of rotations is reduced, and thus the loss is suppressed. Also, the first conveyor 32
When the water content is low, the wheat turns high but the rice is low, thus reducing the damage to the grain in the dry state. Also,
When the moisture value of the first conveyor 32 is intermediate, both the rice and the wheat are rotated at a high speed, so that the conveying force is increased and the occurrence of clogging is suppressed. When the moisture value is higher than a predetermined value, the rotation of each of the rice and wheat is controlled to be low, so that the loss is reduced.

Since the rotation of the handling cylinder 20 is changed according to the moisture value, the grain and the culm are threshed in an optimum state. That is, as an example, when the moisture value is low, the wheat is rotated at a high speed, but the rice is made low, thereby suppressing the damage of the grain during threshing and the occurrence of broken grain culm, and when the moisture value is intermediate. By setting both the rice and wheat at a high rotation speed, threshing is performed efficiently, and when the moisture value is higher than a predetermined value, the rotation of both the rice and wheat is reduced to suppress the occurrence of threshing. In addition, since the rotation of the air blower 23 is configured to change its rotation depending on the moisture value, the air selection can be performed favorably. That is, the blowing fan 23 raises and lowers the water content and the rotation speed in a proportional relationship, increases the rotation speed when the water content is high, and lowers the rotation speed when the water content is low. In the case of, since the rotation is slightly higher, even if the sorting load is greater than that of the rice, the selection is good.

In this case, when the water value of the cereal culm becomes a peculiar value due to, for example, water droplets adhering to the cereal culm, the rotation of the handling drum 20 is low regardless of the water value of the cereal, and Since the Karino 23 is controlled to rotate at the maximum speed, work in an optimal state is realized. Then, the transfer shelf 2 of the swing sorting shelf 26
Above 8 is a cleaning body 4 for cleaning straw dust, dust, mud, and the like.
0, the transfer projections 2 arranged side by side on the transfer shelf 28
The clogging due to the accumulation of foreign matter during the period 7 is removed, and the transfer force is exerted. In this case, since the cleaning body 40 is provided in parallel with the swinging direction of the swing sorting shelf 26 and is provided so as to reciprocate in a direction crossing the swinging direction, the cleaning body 40 is
8 is prevented from being clogged by the sliding contact with the upper surface of the stove 8 due to the attachment of straw dust, dust, mud, and the like. In the embodiment, the cleaning body 40 is constituted by the rotating brush body 41, and the base of the brush rotating shaft 42 at the center of the rotating brush body 41 is mounted on a bearing body 44 provided on the front side of the front plate 43 of the threshing device 3, Since a rotary motor 45 for rotating the brush rotary shaft 42 is provided on the bearing body 44 and a screw shaft 46 is screwed thereto, and the rotation of the moving motor 47 is transmitted to the screw shaft 46, the rotary brush body Reference numeral 41 denotes a bearing body 4 which is constantly rotated by a rotation motor 45 and is rotated by a movement motor 47 in forward and reverse directions.
4 reciprocates, whereby the rotating brush body 41 reciprocates on the transfer shelf 28 to remove straw dust, dust, mud, and the like.
When the rotating brush body 41 is spirally implanted on the brush rotating shaft 42, the rotating brush body 41 rotates to remove straw chips, dust, mud, and the like, while removing the material separated from the transfer shelf 28 at the end side. Since it is conveyed, it is preferable to remove it more reliably.
