BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a No. 2 reduction conveyor and a No. 2 processing apparatus for reducing the No. 2 material sorted by a combine sorting apparatus. Further, the present invention relates to a combine sorting device in which the opening degree of the chaff sheave of the rocking sorting device is automatically adjusted according to the threshing processing amount conveyed in a straw chain or the like.

2. Description of the Related Art First, a technique relating to a second return conveyor and a second processing device will be described. In the combine, the second item after being sorted by the sorting device is sent to the second processing device through the second conveyor and the second reduction conveyor, and after removing the branch branches etc. by the second processing device, the sorting device is again The second recycle cycle to return to is adopted. Examples of these structures include Japanese Patent No. 2589965, Japanese Patent Application Publication Showa (hereinafter referred to as “JP-A”) 61-0210.
26, Japanese Patent Application Laid-Open No. 61-021027, Japanese Utility Model Application Publication Showa (hereinafter, “Actual Development Sho”) 62-004935.
As disclosed in Japanese Utility Model Publication No. 58-055442. Each of these discloses a second processing device in which the rotation axis is arranged in parallel with the rotation axis of the handling cylinder in a plan view. Further, regarding the delivery of the second product from the second reduction conveyor to the second processing device, in all cases, the starting end side surface of the cylindrical body of the second processing device, that is, other than Japanese Patent No. 2589965, a vertically flat starting end face. In addition, a communication hole with the second reduction conveyor is provided. Also in Japanese Patent No. 2589965, the drive shafts of the No. 2 reduction conveyor and No. 2 processing device are common shafts that are diagonally upward. Therefore, the transfer direction of the second product between the second reduction conveyor and the second processing device is the axial center direction of the cylindrical body of the second processing device, and is transferred in a substantially horizontal direction or obliquely upward. It will be.

Next, a technique relating to the automatic adjustment of the opening degree of the chaff sheave of the swing selecting device according to the threshing processing amount will be described. In the combine, the cut culms are shredded while being conveyed by the handling cylinder of the threshing unit, etc., and the falling grains and straw debris fall on the rocking sorting device arranged below the threshing unit. . Then, these grains, straw debris, and the like are subjected to specific gravity sorting and wind sorting when they are dropped and conveyed on a chaff sheave that is laid across in the width direction of the swing sorting device. The chaff sheave is composed of a plurality of chaff fins, and a gren sheave is arranged below the chaff sheave. Kara-miso for wind selection is placed in the lower front of the chaff sheave, and behind the Kara-shib, the first conveyor that conveys the sorted first item in the left-right direction and the second item are conveyed. A second conveyor is installed side by side. In such a configuration, among the grains and straw debris that leak from the chaff sheave, the grains are transported by the first conveyor as the first item and stored in the grain tanks, etc., and the grains and foreign matters are included. The mixed second product is refluxed (reduced) through the second conveyor, while light straw debris is blown away by the sorting wind and discharged outside the machine by the suction fan. Then, in order to improve the sorting accuracy, the amount of leakage from the chaff sieve such as grains and the amount of air from Karato are adjusted in proportion to the amount of grain. That is,
By detecting the amount of straw by the detection means provided in the straw chain,
The opening of the chaff sheave and the amount of sorted wind are changed according to the amount of straw. For example, as shown in FIG. 39, when the detection arm 147 'rotates due to the amount of change in the posture of the chain guide located below the straw chain, the opening of the chaff sheave is operated by the chaff wire 142 connected to the detection arm 147'. The mechanical control of the opening of the chaff sheave is performed.

Further, in the above-mentioned structure, so-called "coarse selection" is performed in the chaff sheave due to the swing and clearance, and so-called "fine selection" is performed in the granive sieve due to the selection wind by Kara and the like and the net of the sieve. .
The leakage amount of grains, straws, etc. from the chaff sieve in this "coarse selection" is uniquely changed by increasing the threshing treatment amount and changing the opening degree of the chaff sieve. Here, when the threshing treatment amount is small or when the opening is small, the amount of grains, straw, etc. that leaks from the chaff sheave is small, and those that do not leak are guided backward and collected on the second conveyor. Then, the second reduction cycle is performed. Also,
Since the amount of grains, straw, etc. that have leaked into the Glensieve from the chaff sieve is also small, floating straw is easily guided to the rear by the sorting wind, and the "sieve" by the mesh is appropriately performed, so "coarse sorting" is performed. It will be done properly.

[0005]

First, as a problem in the technology relating to the second reduction conveyor and the second processing device, the delivery direction from the second reduction conveyor to the second processing device is substantially horizontal or diagonally upward. Due to this, the second product is likely to be clogged between the second reduction conveyor and the second processing device. In particular, when the retention period of the second product in the second processing device is set to be long, this tendency is further enhanced. Further, the No. 2 processing device performs processing while being conveyed by rotation of rotary teeth, but since the moving speed of the grain in the No. 2 processing device, that is, the processing capacity cannot be changed, rice, wheat, etc. The processing condition could not be changed depending on the type of grain. Therefore, if it is set for rice, rice that does not have branch shoots attached, or the grain may be damaged during wheat harvesting work, and if it is set for wheat cutting, there are many branch shoots. The rice had a problem that the branch shoot was not completely removed.
From this, it is an object of the present invention to improve the sorting performance of the sorting device and the accuracy of branching removal, and to make the machine compact.

Next, regarding the technique relating to the automatic adjustment of the opening degree of the chaff sheave of the rocking sorting device according to the threshing processing amount, in the structure shown in FIG. 39, the amount of straw detected by the detection arm 147 'is increased. On the other hand, since the opening of the chaff sheave increases linearly and proportionally, the area of the chaff sheave has been expanded in order to improve the threshing capacity of the threshing machine with a relatively large capacity, and it is necessary when the threshing amount is small. As described above, the opening degree of the 0 chaff sheave became large, the culm was cut off midway, and the ability to select branch infarct grains was decreased. From this, in the present invention, in addition to the above problems, with respect to the increase in the amount of straw, instead of linearly increasing the opening degree of the chaff sheave, a structure for performing opening adjustment commensurate with the increase in the amount of straw The challenge is to provide.

Further, paying attention to the above "coarse selection" and "fine selection", the "fine selection" is appropriately performed when the threshing treatment amount is small or the opening of the chaff sheave is small. No, but if the threshing amount is large,
The situation is different when the opening is large. That is, as the amount of leakage from the chaff sheave increases,
The amount of grains, straw, etc. to be “finely sorted” will increase.
As a result, the transportation of straw by the sorting wind is also hindered, and it is not possible to "sieve" grains, straw, etc., and they accumulate on the grain sieve, and even branch stem grains, panicles, straws in the grains are also accumulated. However, it leaks through the Glensieve and is led to the most conveyor. In other words, even if the threshing treatment amount increases, proper "fine sorting" is not performed, and even branch shoots, panicles, and straws are most guided to the conveyor and collected in the Glen tank. The quality of the grain becomes poor. It can be said that this leads to the second conveyor, and the grains to be subjected to the branching treatment are collected in the Glen tank without being subjected to the branching treatment. From this, in the present invention, in addition to the above problems, even when the threshing treatment amount is large, or even when the opening is large, "fine sorting" is appropriately performed, and the amount of performing the second reduction cycle (hereinafter, It is an object of the present invention to provide a structure in which the "second reduction amount") is increased, the branching treatment is effectively performed, and the sorting ability and the quality are improved.

At this time, the guide is guided so as to drop onto the sorting start portion of the sorting apparatus 1, that is, the front surface of the front feed plate 52. In this embodiment, the arrangement of the grain guide plate 43 is the discharge port 42.
And the opening of the discharge port 42 is widened toward the center side in front view of the machine body.

With the above construction, the following two effects can be obtained. First, as a first effect, one of the inlets 41 and the outlet 42 is set to the upper left side in a front view so that the positional relationship between the inlet 41 and the outlet 42 is the longest distance in the internal space of the second processing apparatus 10, that is, the diagonal relationship. , The other is on the lower right side when viewed from the front, so the second tooth is the rotating tooth 44.
.. and tooth bars 51, 51 .. Next, as a second effect, by applying the second product discharged from the discharge port 42 to the grain guide plate 43, the front feed plate 52 is prevented from randomly scattering the second product.
Can be reliably dropped onto the front surface of the. In this way, by dropping it on the front surface of the front feed plate 52, it is possible to secure a sufficient distance to move the front feed plate 52, diffuse the second product, and thin the grain layer,
The leakage to the conveyor 22 is most likely to occur. That is, the sorting performance can be improved.

Next, as shown in FIG. 7, the second processing cylinder 11 is disposed orthogonal to the machine advancing direction in a plan view, and the rotation direction of the second processing cylinder 11 is the left side surface of the machine advancing direction. Visually, it is clockwise. This second processing cylinder 1
According to the rotation direction of 1 (arrow L in FIG. 7), the input port 41
When the second product to be further fed is discharged from the discharge port 42 below the cylindrical body, it is made to flow toward the front (machine traveling direction) by the flow of wind due to the rotation of the second processing cylinder 11, and the front feed is performed. It comes to be discharged to the front of the plate 52. Thus
A sufficient distance for moving the front feed plate 52 can be secured, the second material can be diffused, the grain layer can be thinned, and the leakage to the conveyor 22 is most likely to occur. That is, the sorting performance can be improved. Further, since the second product after discharge can be reliably applied to the grain guide plate 43 described above, the improvement of the sorting performance by the grain guide plate 43 can be made more effective.

Next, as shown in FIGS. 3, 5, and 9, the axial direction of the second processing cylinder 11 and the axial direction of the handling cylinder 20 provided above the sorting device are orthogonal to each other in plan view. In relation to this, the right-hand side of the second processing device 10 when viewed from the front is substantially left obliquely below the handling body axis G when viewed from the front. This is because the crimp net 31 arranged below the handling cylinder 20 has a shape that follows the side surface shape of the handling cylinder 20 in a front view, and therefore the third quadrant centered on the axial center of the handling cylinder 20 in the front view. In S3, since the horizontal distance between the right end portion of the second processing device in front view and the axial center of the handling cylinder 20 can be configured to be shorter than the barrel radius of the handling cylinder 20, the second processing device is set. It is as close as possible to the axis of the handling cylinder 20.

With the above construction, the following two effects can be obtained. First, as a first effect, since the second processing device 10 can be brought as close as possible to the handling cylinder 20, the lateral width space occupied by the handling cylinder 20 and the second processing device 10 can be made compact, and the sorting device 1 Also, the threshing device 9 can be made compact. Next, as a second effect, since the discharge port 42 provided on the lower right side in the front view of the second processing device 10 can be configured at a position close to the center position of the sorting device 1 in the front view, the discharge port 42 Since the falling second product can be dropped to a position where it is easily diffused in the left-right direction, that is, a position close to the center of the front feed plate 52, the grain layer can be thinned, and the grain to the conveyor 22 can be the first. Leakage is likely to occur. That is, the sorting performance can be improved.

The tooth bars 51, 51, ..., Together with the rotating teeth 44, 44, ... Of the second processing cylinder 11, serve to rub the second object to remove a branch. From this, in order to completely remove the branch,
Tooth bar 51 ・ 51 ・ ・ ・ and rotating tooth 44 ・ 44 ・ ・ ・
It is desirable to delay the feeding of the second product in the right direction on the paper surface of FIG. In other words, it can be said that the longer the length of the second processing device 10, the higher the processing efficiency.

However, when a large amount of second material is sent in, the processing in the second processing device 10 may not catch up and the second processing device 10 may be clogged. On the other hand, if a small amount of the second material is left in the second processing device 10 for a long period of time, the rotating teeth 44, 44 ...
1.51 ... damages the second item, making it impossible to collect high quality grains.

Therefore, there are a plurality of tooth bars 51.51.
.. Of some of the tooth bars 51, 51, ... It was configured to facilitate the flow of objects downstream.

This lead angle is an angle R shown in the development view of the cylindrical body 45 in FIG. 10, and the tooth bar 51 is in a state where the cylindrical body 45 is expanded and in plan view with the inner side surface facing upward.・ 51 ... from the inlet 41 to the outlet 42
It is tilted to the side by the angle R. It should be noted that the number of tooth bars 51, 51, ... Having a lead angle is arbitrary, and is appropriately designed depending on the processing capabilities of the sorting apparatus 1, the second processing apparatus 10, and the like.

In this way, even if the number of secondary treatment is large or small, the secondary treatment can be kept in the secondary treatment device 10 for a proper period for removing the branch vein, and the performance of the secondary treatment device 10 can be maximized. be able to.

Further, a tooth bar 51 having a lead angle
Since 51 makes it easier for the second product to be sent to the discharge port 42 side, the second product is clogged in the second processing device 10 even when the second product is extremely small. Will not occur.

Proportional to the amount of straw. However, in a threshing machine having a relatively large capacity, the area of the chaff sheave 55 is also expanded in order to improve the threshing processing capacity, and the opening degree of the chaff sheave 55 becomes larger than necessary when the threshing amount is small. There is a problem that it is cut off midway and the ability to sort branch shoots is reduced.

Therefore, in the structure according to the present invention, as shown in FIG. 31, the chaff wire 142 with respect to the amount of straw discharged.
The shape of the detection arm 147 is determined so that the amount of change in the stroke (198) of (1) increases. That is, as the amount of straw is increased and the amount of processing is increased, the chaff wire 1
The stroke of 42 is non-linear, in other words, it increases in a parabolic shape, and as shown in FIG. It is trying to increase significantly.

More specifically, as shown in FIG. 33, when the opening of the chaff sheave 55 is at a minimum, the detection plate 14
6, the arm shaft 148 which is the center of rotation, and the detection arm 14
The longitudinal direction of the detection arm 147 is directed to a straight line connecting the chaff wire 142 connected to the wire bracket 195 of the chaff wire 142, and the arm shaft 148, the detection arm 147, the chaff wire 142, and the wire bracket 195 are positioned on a substantially straight line. I am trying to do it. Hereinafter, this structure is referred to as "type A". In addition, in the type B, the detection arm 14
7'is composed of one member, and the chaff wire 142 is attached to one member.
The shutter wire 143 and the shutter wire 143 are connected to each other. However, in the type A, the chaff wire 142 and the shutter wire 143 are on the same straight line because the detection arm 147 has a rotating position, so that the wires do not interfere with each other. The detection arm 147 is composed of two members.

In the type A, when the amount of straw is increased, the detection plate 146 rotates about the arm shaft 148 in the trajectory shown by the arrow 201 in FIG. 34, and the detection arm 147 moves in accordance with the arrow 202. Draw the orbit shown and arm axis 1
It rotates around 48. When the detection arm 147 draws such a trajectory, when the rotation angle of the detection arm 147 increases constantly, the chaff wire 142 and the shutter wire 143 are larger when the amount of straw is large than when the amount of straw is small. The stroke change amount becomes large. Type A
In this case, this tendency is more noticeable than in type B, and the stroke of the chaff wire 142 increases non-linearly as the amount of straw is increased. Greatly increased compared to when the amount is small. As described above, the type A has a simple structure, but good and reliable control can be performed, which contributes to the improvement of the sorting performance. Further, when converting the type B structure to the type A, it is only necessary to replace the detection arm 147 and change the position of the wire bracket 195, so that a structure capable of obtaining good sorting performance at a relatively low cost. Can be changed to

In the shutter wire 143 connected to the detection arm 147 as well as the chaff wire 142 in the type A, the stroke of the shutter wire 143 increases non-linearly as the amount of straw is increased, and the straw is discharged. As the amount increases, the amount of change in the opening degree of the shutters 139 and 140 becomes larger than that when the amount of straw is small, and the amount of air blow can be set according to the threshing amount.

Further, in the above structure, the chaff wire 14
2 is connected to the chaff lever 138, the opening degree of the chaff sheave 55 is changed by mechanical control, and the opening degree is finely adjusted by the switching lever 155 connected to the chaff opening motor 157. The stroke can be adjusted by the chaff opening motor 157 controlled by the controller 194, which will be described below as a second embodiment.

As shown in FIGS. 35 and 36, in the vicinity of the wire bracket 195 of the chaff wire 142 connected to the detection arm 147 'for detecting the amount of straw, a chaff opening which is an actuator for changing the basic angle of the chaff sheave 55 is opened. A degree motor 157 is provided, and the opening adjustment cylinder 15 is driven to expand and contract by the chaff opening motor 157.
8 cylinder arm 168a and wire bracket 195
I am trying to connect directly with. Then, the controller 194 calculates the appropriate opening degree of the chaff sheave 55 based on the information from the sensors such as the chaff position sensor 171 and the sorting flow rate sensor 172, and the chaff opening motor 15
A controller 194 is connected to the motor drive circuit 199 of No. 7 to output the chaff opening motor 157 so that the opening adjustment cylinder 158 is expanded and contracted. Therefore, the chaff wire 142 and the shutter wire 1
The stroke of 43 corresponds to the wire bracket 195 fixed to the cylinder arm 158 a of the opening adjustment cylinder 158.
A small amount is adjusted by adjusting the position.

With the above configuration, the chaff sheave 5
By changing the opening degree of 5 with the chaff lever 138,
Compared with a configuration in which the opening degree is finely adjusted by the switching lever 155, the operation source of the chafever 138 is reduced from two places to one place, and further, the chaff wire 142 for pulling the chafever 138 is controlled near the wire bracket 195. Improvement of control accuracy is expected. Since it is not necessary to adjust the opening degree of the chaff sheave 55 by the switching lever 155, the switching lever 155 and the opening degree adjusting cylinder 1
The switching wire 160 that is connected to the cylinder arm 158a of 58 and the members around it are unnecessary, and the number of constituent parts can be reduced, which is advantageous in terms of simplification of the assembly process and cost reduction.

According to the second embodiment described above, by setting the controller 194, the first embodiment (1 in FIG. 31) is set.
As shown in 98), the wire stroke with respect to the amount of straw can be changed. In addition, type C (2
As shown in 10a), a single or a plurality of standard straw amount (standard threshing treatment amount) (n1, n2 ...) Is determined in advance, and until the standard straw amount (n1, n2 ...) is reached. It is also possible to control so that the wire stroke linearly increases with respect to the amount of straw, and the amount of change in the wire stroke increases with the reference amount of straw (n1, n2 ...) As a boundary. At this time, the opening degree of the chaff sheave 55 with respect to the amount of straw (see FIG. 38).
210), the amount of change in the opening increases with the reference amount of straw (n1, n2 ...) As a boundary. Furthermore, the amount of change can be set to zero not only by increasing the reference amount of straw (n1, n2 ...) As a boundary, but the amount of change can be zero, and the interval of the amount of straw where the opening degree of the chaff sheave 55 is constant. You can also make It is expected that more precise control will be achieved by increasing the number of reference straw amounts (n1, n2 ...). Further, the form of change in the wire stroke as described above is
It is preferable to select a more optimal one depending on the ability and form of the combine.

In this embodiment, the straw processing amount is detected based on the straw amount conveyed by the straw chain, but the method for detecting the threshing processing amount is not limited to this. For example, the threshing treatment amount can be detected by knowing the amount of grain culm conveyed by the feed chain 7 and the treatment amount on the swing sorting device 125.

Next, the opening degree of the chaff sheave is automatically adjusted according to the increase or decrease of the threshing processing amount, and the opening degree adjustment is adjusted so as to be closed when the threshing processing amount is small. The opening degree adjusting mechanism configured as described above will be described. FIG. 40 is a diagram showing an example of a configuration in which the opening degree is freely adjusted to change the predetermined value when the threshing processing amount is smaller than the predetermined value, and FIG. 41 shows another configuration. 42 and 42 are diagrams showing the relationship between the threshing processing amount and the chaff sheave opening in the configuration of FIG. 40 or 41. This configuration is the same as the detection link 145 (FIG. 40) and the detection plate 1.
By mechanically adjusting the distance of 46, the amount of change in the amount of straw required until the detection link 145 acts on the detection plate 146 is changed, so that the amount of straw removal (threshold processing amount) is a predetermined value. The detection link 145 of the detection link 145 is configured to be performed only when the number is larger than the above, the configuration in which the predetermined value is changeable (mechanical control), or the chaff lever 155 is corrected by the controller 194 (chaff opening motor 157). By acting the switching wire 160 on the switching lever 155 (FIG. 24) against the pulling of the chaff wire 142 by the action, the amount of straw (thresholding amount)
Is set only when the value is larger than a predetermined value, and the predetermined value can be changed (electrical control). Here, "when the threshing processing amount is smaller than a predetermined value, the opening degree is adjusted without permission", as indicated by the curve 301 shown in FIG.
It means that the opening degree of the chaff sheave is changed only when the number is larger than 02, and "the predetermined value can be changed" means
This means that the width of the processing amount 302 can be changed.

Specific examples of this configuration will be described below. FIG. 40 shows a configuration in which mechanical control is applied to the configuration of type A above. Detection arm 1
A bracket 241 is arranged in the vicinity of 47, a stay 244 is projectingly provided from the bracket 241, a stopper bolt 242 is screwed into the stay 244 so that the stay 244 can be screwed, and a restriction nut 243 is fastened to the front and the rear of the stay 244. The stopper pin 245 at the tip of the bolt 242 is configured to be able to contact the side surface of the detection arm 147. Then, the adjustment length 79 can be adjusted by screwing the stopper bolt 242. By changing the adjustment length 79, the contact distance 78 between the contact end 77 provided on the bottom of the detection link 145 and the detection plate 146 can be adjusted. Configure to be changeable. In this configuration, when the adjustment length 79 is increased, the contact distance 78 is increased, and conversely, when the adjustment length 79 is decreased, the contact distance 78 is decreased. When the contact distance 78 is increased, a larger amount of straw (thresholding amount) required before the contact end 77 acts on the detection plate 146 is required as compared with before the increase. To be done. That is, a large amount of straw (thushesis processing amount) required until the opening adjustment of the chaff sheave 55 is required, in other words, until the predetermined amount of straw (a predetermined value) is reached, It can be said that the opening adjustment of the chaff sheave 55 is not performed when the opening adjustment is not started or when the opening is smaller than the predetermined value (the amount of straw (threshing amount)). In this way, when the amount of straw (thresholding amount) is small, by keeping the opening degree of the chaff sheave 55 not to be large (minimum), the chaff sheave 55 such as branch grain or straw having a low specific gravity can be obtained. In order to prevent the leakage from the grain, the quality of the grain collected on the first conveyor 22 is improved, and these branch stem grains, straws, etc. are guided to the second conveyor 23 to increase the second reduction amount. The branching process in the second processing device 10 can be performed. 41 shows an embodiment of another configuration of the detection arm 147 and the detection plate 146. In this configuration, as shown by the line 303 in FIG. 42, when the amount of straw is small, the opening degree is The change characteristic is adjusted so that it can be closed freely (in the section 302, the chaff sheave 55 is not opened, and the opening degree is adjusted when the amount of straw (thresholding amount) is larger than a predetermined value). .

Next, electrical control will be described. 22 to 24, the electric control controls the operation of the chaff opening motor 157 by the controller 194, and the chaff wire 14 by the action of the detection link 145.
2 against the pulling force, the switching wire 160 is connected to the switching lever 1
By acting on 55 (FIG. 24), the opening degree of the chaff sheave is adjusted only when the threshing treatment amount is larger than the predetermined value, and the predetermined value can be changed by the controller 194. Further, with the electrical control configuration, the processing amount 302 in FIG. 42 can be configured to be changeable by operating the correction selection adjustment dial 185 (FIG. 20).

Next, a structure will be described in which "fine sorting" is appropriately performed to improve the sorting ability, and the secondary reduction amount is increased to improve the quality. FIG. 43 is a diagram showing a configuration of a sorting apparatus that appropriately performs precise sorting to improve sorting ability, increase the amount of second reduction, and improve quality.

This structure is used before the chaff sieve leaks.
Also, by effectively applying the sorting wind to the grains and straws after the leakage, it is possible to prevent the grains and straws from accumulating on the Glensieve 49, and to perform the “fine sorting” properly. In addition to the above, the grain that has leaked to the first conveyor 22 and is conveyed to the Glen tank 12 is intentionally introduced to the second conveyor 23 to increase the second reduction amount,
The purpose is to improve quality.

That is, as shown in FIG. 43, the No. 1 recovery mechanism for conveying the No. 1 item to the Glen tank via the No. 1 conveyor and the fried conveyor, and the No. 2 item, the No. 2 conveyor and No. 2 reduction conveyor. To the No. 2 processing device, the branching etc. are removed by the No. 2 processing device, and then the second product reduction cycle mechanism for re-inputting into the selection unit, and the air selection mechanism composed of one or more fans And an oscillating sorting device, and an air passage through which sorting wind that flows above the most conveyor flows from the front to the rear. In addition, the first flow grain board that guides the grain to the first conveyor is formed with a slope of front low rear high, and the sorting wind that collides with the first flow grain board forms an air passage that guides diagonally upward to the rear. Is.

The details of the structure and the operation / effect will be described below. As shown in FIG. 43, the first collection mechanism is the first conveyor 22, the fried grain conveyor 13, and the grain tank 12.
(FIG. 1). The second reduction cycle mechanism is the second conveyor 23 / second reduction conveyor 1
The fourth and second processing devices 10 are configured. In addition, the wind sorting mechanism is a dust sending fan 131 which is a pre-fan.
And the main blower, Karato 25.

Further, the rocking / sorting device is, in order from the top, the front feed plate 52 → the rear feed plate 53 / the chaff sheave 55 /
The fixed chaff portion 57 → the grain shedding plate 58 and the grain sheave 49 are provided side by side, and the inside of the swinging body 50 is divided into layers to form a plurality of air passages through which the sorting wind generated by the wind sorting mechanism passes. It is supposed to do.

Regarding this air passage, as shown in FIG. 43, the space between the front feed plate 52 and the rear feed plate 53 is designated as a first air passage 401, and the dust sending fan 131 is provided in the first air passage 401. It is assumed that the first selection wind 501 generated by Since the first air passage 401 is formed by the front feed plate 52 and the rear feed plate 53 that are provided substantially horizontally, the first selection air 501 flows from the front to the rear and also with the suction fan 30. Together with the suction force, it acts to guide lighter grains (immature grains), branch stem grains, straws, etc. leaking from the crimp nets 31 and 21a further backward.

The space between the rear feed plate 53 and the grain plate 58 is the second air passage 402, and the second air passage 402 has
It is assumed that the second selection wind 502 generated by the Karako 25 flows. Since the second air passage 402 is formed by the rear feed plate 53 and the grain plate 58 that are installed substantially horizontally, the second selection wind 502 is flowed from the front to the rear and also with the suction fan 30. Together with the suction force, it acts to guide lighter grains (immature grains), branch stem grains, straws, etc. leaking from the chaff sheave 55 further rearward. Further, a part (502a) of the second selection wind 502 flows so as to escape upward from between the chaff sheaves 55, so that it acts so as to prevent the inflow from the chaff sheaves 55 such as branch inflorescence grains and straw having a low specific gravity. It has become.

Further, the space below the shedding board 58 and the chaff sheave 55 is defined as a third air passage 403, and the third selection air 503 generated by the Karako 25 flows through the third air passage 403. Furthermore, in the third wind passage 403
5, a wind direction guide 525 having a triangular cross-section is laterally provided at a position at the same height as the center of rotation of the Karako 25. This wind direction guide 525 functions to secure the air volume of the third selection wind 503 and control the direction thereof. In this embodiment, the third selection air 503 is divided into two upward and downward flows 503b and 503c. The third upward sorting wind 503b that is formed and flows upward diagonally rearward and the downward downward third sorting wind 503c flows downward diagonally downward. The wind direction guide 525
However, the shape is not limited to a triangular shape in cross section, and may be an arc shape in cross section or a plate shape.
Further, the inclination of the wind direction guide 525 in a side view is configured such that the angle can be arbitrarily adjusted, the wind direction of the third selection wind can be freely changed, and the wind direction of the third selection wind 503 can be finely adjusted. Good. And the above-mentioned third selection wind 503
The b-503c is caused to flow from the front to the rear and, in combination with the suction force with the suction fan 30, collides with the first-flow grain board 410 without wind force loss.

This first-grade grain board 410 is the first conveyor 2
2. The upper end is arranged obliquely rearward and upward from 2, and the upper end is arranged below the rear end of the Glensieve 49.
Is separated from the space 405 in which is arranged. Here, the inclination of the first-flow grain board 410 is set to a front low rear height (approximately 30 degrees in this embodiment). Then, due to the inclination of the first flow grain plate 410, the wind direction of the third selection winds 503b and 503c is changed to be directed obliquely upward. Due to the change of the wind direction as described above, an air flow 503a that flows from the first conveyor 22 through the chaff sheave 55 and into the suction fan 30 is generated on the upper surface of the first-flow grain board 410, and this air flow 5
03a passes through the Glensieve 49 and goes to the first conveyor 2
The first conveyor 2 for branching grains, panicles, straws, etc. with a low specific gravity by blowing up grains, straws, etc.
It acts to prevent the inflow to 2. Regarding the downward third sorting wind 503c, when colliding with the first-flow grain board 410, a part of the wind direction becomes downward (third sorting wind 503d) and adheres to the surface of the first-flow grain board 410. The grain that has been made is effectively guided to the most conveyor.

As described above, the three types of sorting air 501, 502, 50
3 is each air passage 401.4 at the uppermost conveyor.
In 02.403, the air is flown from the front to the rear, and in each of the air passages 401, 402, 403, the wind speed is secured in a wide range from the front part to the rear part of the sorting device, and from the crimp nets 31.21a. It is possible to improve the ability to sort out leaked grains and straws. In addition, the first and second selection wind 501.
In the case of 502, a branching grain with a low specific gravity is floated because it flows from the front to the back at the top of the conveyor.
Ear cuttings, straw, etc.
Before the plant is landed on the floor, it is guided to the second conveyor 23 to perform “fine sorting” properly, and at the same time, the grain seeds 49, the cuttings, and straw grains in the grains to be planted and deposited on the Glensieve 49. As a result, the content rate of etc. will be reduced, and high quality grains will be recovered. Also, the third sorting wind 50
In No. 3, in the uppermost part of the conveyor, it flows from the front to the rear, which prevents branching grains, panicles, straws, etc. having a small specific gravity from passing through the Glensieve 49 and flowing into the first conveyor 22. At the same time, as a result, the amount of grains, branch stems, and the like introduced to the second conveyor 23 is increased, so that the amount of grains, branch stems, and the like subjected to the branch stem treatment by the second reduction cycle can be increased. it can. As described above, even when the threshing treatment amount is increased, the inflow of branch stem grains, panicle cutting grains, straw, etc. into the first conveyor 22 is prevented, and these are removed by the second reduction cycle. By carrying out the treatment / re-sorting, it is possible to improve the quality of the grains finally collected in the grain tank 12, and it is possible to prevent a reduction in the collected amount of grains due to a sorting loss.

Next, in connection with the adjustment of the opening degree of the chaff sheave, a configuration will be described in which "fine sorting" is appropriately performed to improve the sorting ability, and the secondary reduction amount is increased to improve the quality. . This configuration is the amount of straw (thresholding amount)
When the chaff sheave 55 has a large opening and the amount of leakage from the chaff sheave increases,
Grains before and after leakage of chaff sieve
Effectively applying sorting wind to straw, etc. prevents grain and straw etc. from accumulating on the Glensieve so that "fine sorting" can be performed properly and it also leaks to the first conveyor 22. By deliberately guiding the grain that is being conveyed to the lowering grain tank 12 to the second conveyor 23,
The second reduction amount is increased to improve the quality.
On the other hand, when the amount of straw (thresholding amount) becomes small, the chaff sheave 55 as described in FIGS. 31 and 32 (also in FIGS. 37, 38, and 42).
With the advantage that the opening degree of is kept small (improvement of change characteristic), the leakage amount to the first conveyor 22 is minimized and the quality is improved by guiding it to the second conveyor 23. Is. In addition, by automatically adjusting the opening degree of the chaff sheave according to the threshing treatment amount, the amount of leakage from the chaff sheave is optimal for the predetermined threshing treatment amount, thereby improving the sorting ability. .

That is, as shown in FIG. 43, the No. 1 recovery mechanism for conveying the No. 1 item to the Glen tank via the No. 1 conveyor and the grain lifting conveyor, and the No. 2 item, the No. 2 conveyor and No. 2 reduction conveyor. To the No. 2 processing device, the branching etc. are removed by the No. 2 processing device, and then the second product reduction cycle mechanism for re-inputting into the selection unit, and the air selection mechanism composed of one or more fans And an opening adjustment mechanism that automatically adjusts the opening of the chaff sheave according to the increase or decrease of the threshing processing amount,
The swing sorting device and the sorting wind flowing above the most conveyor,
It is provided with an air passage which flows from the front to the rear.
As shown in FIG. 43, the opening adjustment mechanism employs the “first embodiment of the first embodiment” in the structure for adjusting the opening of the chaf sheave 55 described above, and mechanically adjusts the opening of the chaf sheave 55. It is controlled (adopts the configuration of FIGS. 19 and 20). In addition, you may employ | adopt the said "2nd form of 1st Example" provided with the selection flow rate sensor 172. With this opening adjustment mechanism, the optimum opening degree of the chaff sheave corresponding to the amount of straw (thresholding amount) is set.

The increase in the second reduction amount in this structure will be described below. When the amount of straw is large and the amount of threshing treatment is large, the opening of the chaff sheave 55 is increased by the rotation of the chaff lever 138, and the amount of leakage from the chaff sheave 55 to the grain sheave 49 is increased. Further, along with this, the amount of leakage from the grain sieve 49 to the first conveyor 22 also increases. In such a case, in the same manner as above, the inflow of branch stem particles, panicle cutting grains, straw, etc. into the first conveyor 22 is blocked, and they are subjected to branch stem removal treatment / re-sorting by the second reduction cycle. By doing so, the quality of the grains finally collected in the grain tank 12 can be improved, and the reduction in the amount of collected grains due to the selection loss can be prevented.

On the other hand, when the amount of straw is small and the amount of threshing treatment is small, the chafever 138 is rotated to
The opening degree of the chaff sheave 55 becomes smaller. Here, regarding the opening degree of the chaff sheave 55 when the amount of straw (thresholding amount) is small, the same applies to the case of the second embodiment shown in FIGS. 31 and 32 (FIG. 37 and FIG. 38). And the same applies to the configuration shown in FIG. 41), the opening of the chaff sheave is self-closing (meaning that the increase in the opening of the chaff sheave with respect to the increase in the amount of straw is small), and the amount of straw (threshold) is reduced. When the throughput is small,
In particular, branch stem grains, panicle grains, straw, etc. are in a state in which it is difficult for the chaff sheave 55 to leak. And chaff sheave 5
As the amount of leakage from 5 to Glensieve 49 decreases, the grains, straws, etc. floating in the air passages 401/402 or landing on the chaff sheave 55 / Glensieve 49 are fixed chaff by the sorting air 501/502. By being guided to the section 57 and leaking to the second conveyor 23, the second reduction amount is increased. In this way, in addition to the transportation of grains, straws, etc. to the rear part by the action of the sorting wind, the above-mentioned change characteristic of the opening degree of the chaff sheave 55 is improved (FIGS. 31 and 3).
2, FIG. 37, FIG. 38, and FIG. 42), it is possible to reliably increase the second reduction amount even when the amount of straw (thresholding amount) is small. Then, the inflow of branch stem particles, panicle cutting grains, straw, etc. into the first conveyor 22 is reduced, and the branch stem removal processing and re-sorting are performed by the second reduction cycle, so that the grain tank 12 is finally obtained. It is possible to improve the quality of the grains collected in the above step and prevent the reduction of the amount of grains collected due to the sorting loss.

The structure described above, that is, the first recovery mechanism for transferring the first product to the Glen tank via the first conveyor and the fried food conveyor, and the second product for the second conveyor and the second reduction conveyor. To the No. 2 processing device, the branching etc. is removed by the No. 2 processing device, and then the No. 2 reduction cycle mechanism to re-introduce into the selection unit, and the air selection mechanism composed of one or more fans The opening degree of the chaff sheave is automatically adjusted according to the increase or decrease in the threshing processing amount, and the opening degree is adjusted so that the opening degree is adjusted freely when the threshing processing amount is small. The degree adjustment mechanism, the swing sorting device, and the configuration that has the airflow path that allows the sorting wind that flows above the most conveyor to flow from the front to the rear are adopted, and the threshing is performed under the condition of the predetermined threshing treatment amount. Collected on the conveyor and second conveyor A comparison of the amounts of branch stem particles showed that the number of branch stem particles collected on the No. 2 conveyor was more than three times the number of branch stem particles collected on the first conveyor. It was Incidentally, the amount of branch embers collected on the second conveyor is usually measured by collecting and measuring the second material that is being conveyed to the second conveyor. Shall also include panicles. In this way, most of the branch shoot grains are collected on the No. 2 conveyor and subjected to the No. 2 reduction cycle, subjected to the branch shoot removal treatment, and finally, a good quality grain without branch shoots. As a grain, it will be collected in the No. 1 conveyor and the Glen tank. As described above, according to the configuration of the present embodiment, the sorting capacity is dramatically improved, and the second reduction amount is increased,
Ultimately, the quality of the grain collected in the Glen tank is improved.

[0104]

Since the present invention is constructed as described above, it has the following effects. That is, as described in claim 1, in a combine second processing device equipped with a second conveyor and a second reduction conveyor for reducing and transporting the second material after selection to the selection section, the second processing cylinder is provided in the cylindrical body. Is rotatably housed to form a No. 2 processing device, an inlet is provided on the circumferential surface of the cylindrical body, an opening at the end of the No. 2 reduction conveyor is provided at the inlet, and No. 2 is the cylindrical body. Since it is connected so that it will be dropped and thrown into, it is possible to throw in the second object returned from the second conveyor in the cylinder, and the second object is blocked at the end of the second conveyor. Don't worry.

Further, as described in claim 2, the charging port is provided near one end of the cylindrical body of the second processing device and communicates with the second reduction conveyor.
Since the discharge port is provided at the other end of the cylindrical body and the discharge port is arranged at the starting portion of the sorting device, the second product effectively acts on the rotary teeth and the tooth bar of the second processing cylinder. It is possible to increase the efficiency of branch branch removal.

Further, as described in claim 3, since the axial direction of the second processing cylinder and the axial direction of the handling cylinder provided above the sorting device are orthogonal to each other in plan view, the second processing is performed. The discharge port provided on the lower right side in the front view of the device can be configured at a position close to the center position of the sorting device in the front view, and a second object falling from the discharge port is easily diffused in the left-right direction, that is, Since it can be dropped to a position close to the center of the first feed plate, the grain layer can be thinned and leakage to the conveyor can be facilitated.
