Description

Separator and processing device 2 of the combine {SEPARATER AND TAILING RETURNING SYSTEM IN A COMBINE HARVESTER}

The present invention relates to a sorting device for combines.

Particularly, the oscillation screening apparatus is sorted according to the structure of the second reduction processing mechanism for reducing the second matter sorted by the sorting device, treating the waste and returning it to the sorting device, and the amount of straw straw discharged to the straw straw discharge chain. It relates to the structure of a mechanism for automatically adjusting the opening degree of a sieve.

First, the prior art regarding No. 2 reduction conveyor and No. 2 processing mechanism is described.

In the conventional combine, the second object after sorting from the sorting apparatus is sent to the second treating mechanism through the second conveyor and the second reducing conveyor, and the second is returned to the sorting apparatus after removing the diameter and the like by the second treating mechanism. The redundancy reduction cycle is adopted. As a conventional structure, for example, Japanese Patent No. 258965, Japanese Patent Application Laid-Open (hereinafter referred to as Japanese Patent Application) 61-021026, Japanese Patent Application Laid-Open No. 61-021027, and Japanese Utility Model Application Laid-Open So) 6-004935, and as disclosed in the real number 58-055442.

All of them disclose the second processing mechanism in which the rotation axis is arranged in parallel with the rotation axis of the barrel in plan view.

In addition, in regards to the replacement of the second product from the second reduction conveyor to the second treatment mechanism, the second reduction conveyor and the second reduction conveyor are placed on the start side of the cylindrical body of the second treatment mechanism, that is, in a vertically flat start surface. Communication holes are formed. Also in Japanese Patent No. 2589965, the drive shafts of the No. 2 reduction conveyor and the No. 2 processing mechanism become the common axis in the inclined direction. Therefore, the exchange direction of No. 2 between the No. 2 reduction conveyor and the No. 2 treatment mechanism is the axial direction of the cylinder of the No. 2 treatment mechanism, and is substantially exchanged upwardly or horizontally.

Next, a description will be given of the prior art regarding the automatic adjustment of the opening degree of the sorting body of the rocking-selection mechanism according to the threshing throughput.

In the conventional combine, the cut crest is detached while being conveyed by the barrel copper of the threshing portion, and the falling grain, straw gum, and the like fall to the swing selection mechanism disposed below the threshing portion. These grains, straw gum, etc. fall on the sorting body (chave sheave) which spans the width direction of the said rocking | crossing selection mechanism, and specific gravity sorting and balloon sorting are performed at the time of conveyance.

The sorting body is constituted by a plurality of chaff pins, and grain sheaves are provided below the sorting body. And, in the lower part of the front of the sorting body, a tuyere for wind sorting is arranged, and in the rear of the tuyere, a No. 1 conveyor for conveying the sorted No. 1 goods in the left and right directions and a No. 2 conveyor for transporting the No. 2 goods are installed. It is.

In such a configuration, among the grains and straw gums falling from the sorting body, the grains are conveyed by the first conveyor as the first article and stored in the grain tank, etc., and the second article with the grains and contaminants mixed is the second conveyor and the second. While being refluxed (reduced) through the reduction / reduction conveyor, light straw gum and the like are blown off by the selection wind and discharged to the outside by the suction fan.

In order to increase the screening accuracy, the amount of missing from the screening bodies such as grains and the air volume of the tuyere are adjusted in proportion to the amount of crests. That is, the amount of straw straw discharged by the detection means provided in the rice straw discharge chain is changing the opening degree of the sorting body or the amount of the selection wind according to the amount of straw straw discharged. For example, as shown in FIG. 39, when the detection arm 147 'is rotated by the posture change amount of the chain guide located under the straw straw discharge chain, it is selected by the chain wire 142 connected to the detection arm 147'. Mechanical control of the opening degree of the sorting body which manipulates the opening degree of a sieve is performed.

In the above structure, so-called "coarse screening" is performed in the sorting body by fluctuations and gaps, and in grainsing, the so-called "species" is determined by the sorting wind by grain openings and the net thickness of the grains. Screening ”.

The amount of missing grains, straws and the like from the sorting body in this "selection" is uniquely changed by increasing the threshing treatment amount or changing the opening degree of the sorting body.

Here, when the amount of threshing treatment is small or when the opening degree is small, the amount of threshing and straw that falls out from the sorting body is small, and the one that does not fall out is guided backward and recovered to the No. 2 conveyor (No. 2 reducing conveyor). Reduction cycle is carried out. In addition, since grain and rice straw dropped from the sorting body to grainy are small in quantity, the floating rice straw is easily introduced to the rear by the sorting wind, and "sieving" by the manhole is appropriately performed. Will be done.

First, as a problem in the prior art regarding the No. 2 reduction conveyor and the No. 2 processing mechanism, the transfer direction from the No. 2 reduction conveyor to the No. 2 processing mechanism is substantially horizontal or inclined upward. No. 2 water is easily blocked between the reduction conveyor and No. 2 treatment equipment. In particular, if the holding period of the second product in the second treatment mechanism is set longer, this tendency is stronger.

In addition, while the second processing mechanism is processed while conveying by rotating the rotary teeth, the moving speed of the grain in the second processing mechanism, that is, the processing capacity cannot be changed, so the processing method is changed according to the type of grain such as rice or barley. Could not change

Therefore, in the case of setting for rice, rice with no diameter (or ear) or the grain may be damaged during barley harvesting operation. There was a problem that this was not completely removed.

For this reason, the present invention aims to improve the sorting performance of the sorting device, the accuracy of removing the diameter, and to reduce the size of the gas.

Next, with respect to the prior art according to the automatic adjustment of the opening degree of the sorting body of the swing selection device according to the threshing processing amount, the conventional structure shown in Fig. 39 checks the increase in the amount of rice straw discharge detected by the detection arm 147 '. Since the opening amount of the sieve increases linearly in proportion, the area of the chief sheave is expanded to improve the threshing capacity in the relatively large threshing machine, and the opening degree of the selection body becomes larger than necessary in the state where the threshing amount is small. It cuts along the way, or the screening ability of the hard ribs decreased.

In view of the above, the object of the present invention is to provide a structure in which the opening degree of the selection body is adjusted linearly in accordance with the increase in the amount of straw straw discharge, in addition to the increase in the rice straw discharge amount. .

In addition, when focusing on the said "chosen distinction" and "selection distinction", when there is little threshing process amount or when the opening degree of a sorting body is small, there is no problem because "selection differentiation" is performed appropriately, but when threshing processing amount is large In the case where the opening degree is large, the situation is different.

That is, with the increase of the amount falling from the sorting body, the amount of grain, straw, etc. which become "sorting" will increase. Then, the transfer of rice straw due to the sorting wind is also hindered, and grains, straws, and the like cannot be "completely sieved", and the grains are deposited on the grainy grain, and the grains, water cuttings, and straws in the grain are grained. It will fall and be guided to the number 1 conveyor.

Eventually, with respect to the increase in threshing throughput, no appropriate "selection" is carried out, and even tillage, water cutting, and rice straw are guided to the No. 1 conveyor, resulting in poor quality of the grains recovered by the grain tank. This can be said to be guided to the second conveyor, so that the grain to be subjected to the diameter treatment is recovered in the grain tank without the diameter treatment.

For this reason, in the present invention, in addition to the above-mentioned problem, "selection" is appropriately performed even in the case where the threshing treatment amount is large or the opening degree is large, and the amount of performing the second reduction cycle (hereinafter referred to as "second reduction amount"). It is an object of the present invention to provide a structure for increasing the screening capacity, effectively performing the surface treatment, and improving the screening ability and quality.

First of all, an object of the present invention is to configure a second reduction treatment mechanism in a combine sorting apparatus having a compact and high reduction treatment capability of the secondary product.

Therefore, the present invention firstly provides a combiner having a second conveyor and a second reduction conveyor for returning the second batch after sorting to the sorting section, wherein the second batch is rotatably housed in the cylinder to provide a second process. A burner processing mechanism is formed, and an inlet is formed in the circumferential side surface of the cylinder, and the opening of the end of the second reduction conveyor is communicated with the inlet so that the second object falls into the cylinder. Thereby, the 2nd thing reduced from the 2nd conveyor can be thrown in the cylinder of a 2nd processing mechanism, and there is no fear of clogging the 2nd thing in the terminal of a 2nd conveyor.

The inlet is formed near one end of the cylinder of the second treatment mechanism, communicates with the second reduction conveyor, and forms an outlet at the other end of the cylinder, and arranges the outlet toward the start of the sorting apparatus. . By the configuration of the second treatment mechanism, the second object can be effectively acted on the rotary teeth and the tooth bar of the second treatment cylinder, and the efficiency of removing the diameter can be improved.

Moreover, the axial direction of the said 2nd process cylinder and the axial direction of the barrel provided above a sorting apparatus have an orthogonal relationship in planar view. Thereby, the discharge port provided in the lower right side when viewed from the front of the 2nd processing mechanism can be comprised in the position near a center position when seen from the front of the sorting apparatus, and the 2nd thing falling from the said discharge port spreads to the left-right direction. Since it can fall to a position which is easy to be ie, the position near the center of a 1st feed plate, a grain layer can be made thin and it can make it easy to pull out with a No. 1 conveyor. That is, the screening performance can be improved.

The second processing cylinder is arranged orthogonal to the gas traveling direction when viewed in a plan view, and the rotational direction of the second processing cylinder is clockwise when viewed from the left surface of the gas traveling direction. As a result, when the second article is discharged from the discharge port, it flows toward the front (gas advancing direction) by the wind flow caused by the rotation of the second treatment cylinder, and is reliably discharged to the front of the first feed plate, and the second article is sufficiently discharged. By spreading, the grain layer can be made thin, which makes it easier to fall to the No. 1 conveyor. That is, improvement of the selection performance is intended.

The present invention further provides a control valve in the second processing mechanism, and configures the control valve so that the angle can be adjusted. That is, the control valve can be rotated to change the feed speed of the grain in the second processing mechanism. Therefore, in the rice or barley mowing operation to which no diameter is attached, the grains inside the second processing mechanism are quickly discharged, thereby eliminating the damage of the grains. In the case of rice having a large diameter, grains are kept in the second treatment mechanism for a long time and the grains are rubbed to remove the diameter and improve the selectivity.

Further, a plurality of the control valves are provided so that each control valve can be connected by a connecting means, and the plurality of control valves can be simultaneously changed in angle. This makes it possible to adjust the plurality of control valves at the same angle at a time by moving the lever, and the adjustment becomes easy.

The present invention is configured to be inclined so that the exit side goes down the center line of the cylinder surrounding the second treatment cylinder in the second treatment mechanism. By doing so, no grains or the like remain in the cylinder at the end of the work, and cleaning and the like can be facilitated.

The present invention further provides an access to the cylinder by arranging the cylinder of the second processing mechanism on the back side of the grain tank and opening the grain tank. As a result, by opening the grain tank, maintenance management such as inspection and repair of the second treatment mechanism can be performed, and adjustment and cleaning of the control valve can be facilitated.

Next, an object of the present invention is to provide a rocking | throwing-screen selection mechanism by which the sorting effect is acquired suitably according to threshing process amount.

Thus, the present invention is a combination sorting device that automatically adjusts the opening degree of the sorting body of the rocking screening mechanism, wherein the amount of change in the opening degree of the sorting body is small when the threshing throughput is small, and large when the threshing throughput is large. It is preferably controlled to increase the parabolic curve with increasing threshing throughput. Specifically, in the configuration in which the detection arm for detecting threshing throughput and the chaperber for manipulating the opening degree of the sorting body are connected by wires, when the rotational angle of the detection arm is constantly increased, when the amount of rice straw discharged is large, the amount of rice straw discharged is small. In comparison with this, the amount of change in the stroke of the chaff wire is increased. Thereby, the opening degree of the sorting body according to the threshing processing amount becomes more, and it contributes to the improvement of sorting ability.

The amount of change in the degree of opening of the sorting body with respect to the increase in the threshing throughput may be changed to be initiated on the basis of an arbitrarily set reference threshing throughput. That is, the opening degree of the sorting body is kept constant until the standard threshing throughput is reached. In addition, by setting this standard threshing treatment amount appropriately according to the change of rice straw discharge amount, it becomes a more detailed and favorable opening degree change of a sorting body according to threshing processing amount, and contributes to the improvement of sorting ability.

Further, an actuator for changing the opening degree of the sorting body is provided, and the opening amount control of the sorting body is performed by a controller for the operation amount of the actuator. This makes it possible to reliably control the selection body opening degree, and to control the opening degree of the selection body with higher accuracy than when mechanically controlling the opening degree of the selection body.

In this manner, a combine sorting apparatus configured to automatically adjust the opening degree of the sorting body of the oscillation screening mechanism in accordance with the threshing processing amount is configured as follows. That is, a wire arm, a detection arm, and a detection arm for supporting the wire on the body side with a minimum opening degree of the sorting body formed by connecting a detection arm for detecting threshing processing amount and a chaperber for manipulating the opening degree of the sorting body with a minimum opening degree. The center of rotation of the arm is configured to be approximately colinear.

In this way, when the rotational angle of the detection arm is constantly increased, when the amount of straw straw discharged is large, the amount of change in the stroke of the chaff wire is increased compared to when the straw straw discharged is small, and the opening degree of the sorting body is changed according to the threshing throughput. Contribute to improving screening capacity. In addition, since the simple structure, the assembly process is easy, and even if a broken member only needs to be replaced, the cost associated with maintenance can be reduced at a low cost.

Next, an object of the present invention is to provide a sorting device having a high sorting efficiency due to the action of both the balloon sorting device and the swinging sorting device in the combine sorting device.

Thus, the sorting apparatus of the present invention sends the first water to the second processing mechanism through the first and second recovery mechanism for conveying the first water to the grain tank through the first conveyor and the grain cereal conveyor, and the second conveyor and the second reduction conveyor, The second water reduction cycle mechanism which removes the diameter and the like by the second treatment mechanism and then re-injects it to the selection unit, the balloon separation mechanism composed of one or a plurality of fans, the swing selection mechanism, and the first flow above the conveyor It shall be provided with the air path which flows wind from front to back.

With this configuration, the grain selection, water cutting, straw, etc., which have a small specific gravity due to the sorting wind, are guided to the rear and the second conveyor before being placed on the grain-selective body or the like, so that the "selection" is appropriately performed and the grain is grained. It is possible to recover high-quality grains by reducing the content of local grains, water cuttings, and straws in grains that are implanted and deposited on sieves and sorting bodies.

In addition, in the sorting apparatus having such a configuration, the opening degree adjusting mechanism automatically adjusts the opening degree of the sorting body in accordance with the increase and decrease of the threshing processing amount. In the case of a small amount of rice straw discharge (threshing throughput), the number of conveyors does not increase the opening degree, that is, by maintaining the minimum opening degree, it is possible to prevent falling out of the selection body such as small grains and rice straws with low specific gravity. In addition to improving the quality of the grains to be recovered in the oven, the second granules and rice straws are guided to the second conveyor (and the second reduction conveyor) to increase the second reduction, and the diameter treatment in the second processing mechanism is performed. can do. In addition to improving the sorting ability by the sorting wind, it is possible to promote an increase in the second reduction.

In addition, the first conveyor plate to guide the grain to the first conveyor to form a slope of the front and rear high, and the wind path for guiding the sorting wind impinging on the first curved plate to the rear inclined upward. As a result, the upper surface of the first grain plate is provided with a specification that flows through the sorting body from the No. 1 conveyor and flows into the suction fan, and blows the grain, straw, etc. that the air flows through the Grainy and tries to fall to the No. 1 conveyor. It increases the amount of grain, grain, etc. guided to No. 2 conveyor by increasing the amount of grain, grain cutting, rice straw, etc. The amount of grains, grains, and the like to which the diameter processing is performed increases, and the sorting ability is improved.

On the other hand, in the embodiment of Fig. 5, the second processing mechanism 10 having the second processing cylinder 11 (Fig. 5) is disposed near the end of the second reduction conveyor 14, and The second process cylinder 11 is driven by transmitting power.

In addition, the power of the second conveyor 23 is transmitted to the conveyor shaft 34 of the second reduction conveyor 14.

In the embodiment of FIG. 4, the load of the second processing mechanism 10 affects the second reducing conveyor 14, and the drive transmission member between the second reducing conveyor 14 and the second processing mechanism 10 ( The bevel gears 36 and 37) and the said member must increase weight in order to ensure rigidity.

On the other hand, in the embodiment of Fig. 5, since the rotational drive of the second processing cylinder 11 does not need to be removed from the second reduction conveyor 14, the electric path is shortened and the bevel case and the like can be eliminated. It is possible to reduce the cost by reducing the score, simplify the structure, and reduce the weight.

In addition, since the burden of the drive of the 2nd processing cylinder 11 is not added to the 2nd reduction conveyor 14, the conveyor shaft which needs sufficient strength to function also as a drive transmission shaft in the Example of FIG. 4, for example. It becomes possible to function only the 34 as a rotating shaft, and to form a drive shaft thinly. In this way, the weight of the components can be reduced.

In addition, in this embodiment, although the structure which transmits through the drive chain 32 and the sprocket 33 from the tuyere 25 is shown, it rotates to the 2nd process cylinder 11 from the 1st conveyor 22 (FIG. 5). It is good also as a structure which transmits a drive.

Next, the second processing mechanism 10 will be described.

As shown in Figs. 6 to 8, the second processing mechanism 10 arranges the second processing cylinder 11 below the front end of the second reduction conveyor 14, and transverses the drive shaft 11a in the horizontal direction. I install it.

On the outer circumferential surface of the second processing cylinder 11, rotary teeth 44, 44,... Are arranged at appropriate intervals. The second processing cylinder 11 is housed in the cylinder 45, and an inlet 41 is formed in the circumferential surface of the upper rear portion near the one end (right end in this embodiment) of the cylinder 45, thereby reducing the number 2 reduction conveyor. In communication with (14). Therefore, the second article exchanged from the second reduction conveyor 14 to the second processing cylinder 11 is in the form of falling downward. To the inner surface of the cylinder 45, toothed bars (fixed-side processing blades) 51, 51, ..., and control valves 63, 63, 63 to be described later are provided.

The second processing mechanism 10 is located on the left side of the sorting device 1 on the back side of the grain tank, that is, on the right side of the grain tank as viewed from the front. Therefore, maintenance of the second processing mechanism 10 is made possible by opening the grain tank 12. That is, the second processing mechanism 10 is installed on the rear side of the grain tank and is accessible by opening the grain tank, that is, maintenance management such as inspection or repair of the second processing mechanism 10 from the open side of the grain tank. It is possible.

Moreover, the discharge port 42 is formed below the other end (left end) of the cylinder 45, and is arrange | positioned facing the start part of the sorting apparatus 1. As shown in FIG. The grain guide plate 43 is disposed in the vertical direction at the front portion or the side portion of the discharge port 42 so as to prevent the falling grain from scattering.

Here, with respect to the attachment structure of the second processing mechanism 10 and the second reduction conveyor 14, in the second reduction processing mechanism in which the second processing cylinder 11 is rotatably driven to the cylinder 45, the cylindrical body An inlet 41 is formed in the upper surface (right upper rear) of the 45, and the opening of the end of the 2nd reduction conveyor 14 is made to communicate with the said inlet, and the 2nd object from upper with respect to the 2nd process cylinder 11 is carried out. Is configured to drop in.

In this way, the second processing cylinder was accommodated in the cylinder so as to be rotationally driven to constitute the second reduction processing mechanism, an inlet was formed in the circumferential surface of the cylinder, and the opening of the end of the second reduction conveyor was connected to the inlet. Therefore, the second article reduced from the second reduction conveyor can be thrown into the cylinder without leaving, and the second article is hardly attached to the inner side of the opening of the end of the second reduction conveyor (the second article is removed from the opening). Because of free fall, there is no fear of clogging the second product at the end of the second reduction conveyor.

In addition, as shown in Fig. 8, the second processing mechanism 10 has one side (right side when viewed from the front of the body) of the cylinder 45 in the opening formed in the partition wall 80 on the grain tank side of the barrel 20. Inserting the outlet 42 in the partition 80, and inserting the flange plate 81 between the outer periphery of the cylinder 45 and the partition 80, and the flange plate 81 is partitioned ( The bolt is fixed to the 80 to be supported and fixed to the partition 80. That is, the space (rapid chamber) in which the barrel 20 is accommodated is formed by the cylinder 45, and the two spaces are joined by the flange plate 81, thereby forming one sealed space in both spaces. Moreover, the partition wall 88 is provided continuously in the upper part of the said partition 80 in the side of the barrel 20, and it is set as the structure which divides a supply chamber and an external space.

According to the above configuration, when a problem occurs in the second treatment mechanism 10, it is possible to easily extract the second treatment mechanism 10 into the assembly by simply removing the flange plate 81, thereby maintaining maintenance. Sex and workability are improved.

In this configuration, since the No. 2 reducing conveyor 14 and the No. 2 processing mechanism 10 are completely constituted separately, the No. 2 reduction in the case of the problem of the No. 2 processing mechanism 10 as described above. The conveyor 14 can be handled separately without being separated, and can flexibly respond to a change in the capacity of the second processing mechanism 10 corresponding to the threshing throughput and a design change in the fine adjustment of the attachment angle.

In the above configuration, the flow of the second water from the second reduction conveyor 14 will be described. After the second water is introduced into the second treatment mechanism 10 from the inlet 41, the second treatment cylinder 11 is rotated. Installed so as to protrude to the inner teeth of the rotary teeth 44, 44,... Which are provided on the outer circumference of the second treatment cylinder 11 and the cylinder 45 constituting the outer frame of the second treatment mechanism 10. A grain guide plate disposed in the vicinity of the outlet port 42 after being conveyed to the outlet port 42 while being discharged downward from the outlet port 42 while removing the diameter by one tooth bar 51, 51,. 43), it is guided to fall on the sorting start portion of the sorting device 1, i.e., on the front surface of the front feed plate 52.

In this embodiment, the grain guide plate 43 is arranged in front of the outlet 42, and the opening of the outlet 42 is widened from the front side to the center side.

And the following two effects are acquired by the above structure.

First, as a first effect, the left side when viewed from the front so that the positional relationship between the inlet 41 and the outlet 42 becomes the longest distance in the internal space of the second treatment mechanism 10, that is, the diagonal relationship; Since the upper side and the other side are the lower right side when viewed from the front, the second object is effectively applied to the rotary teeth 44, 44,... And the toothed bars 51, 51,. Can be operated, and the efficiency of the removal of the diameter can be increased.

Next, as a second effect, the second object discharged from the discharge port 42 is brought into contact with the grain guide plate 43, so that the second object is not scattered on the front surface of the front feed plate 52 without any manipulation. It can fall down surely. In this way, by dropping on the front surface of the front feed plate 52, the distance for moving the front feed plate 52 is sufficiently secured, the second object can be diffused, and the grain layer can be made thin, and the first conveyor ( It is easy to omit to 22). That is, improvement of the selection performance is intended.

Next, as shown in Fig. 7, the second processing cylinder 11 is arranged orthogonal to the gas traveling direction in a plan view, and the rotational direction of the second processing cylinder 11 is on the left side of the gas traveling direction. Seen in clockwise direction.

When the second object introduced from the inlet 41 is discharged from the outlet 42 under the cylindrical body by the rotational direction (arrow L in FIG. 7) of the second treatment cylinder 11, the second treatment cylinder It flows toward the front (gas advancing direction) by the wind flow by rotation of 11, and it is discharged to the front of the front feed plate 52.

In this way, the distance for moving the front feed plate 52 is sufficiently secured, the second object can be diffused, the grain layer can be made thin, and the first conveyor 22 can be easily pulled out. That is, improvement of the selection performance is intended.

In addition, since the second article after discharging can be reliably brought into contact with the above-mentioned grain guide plate 43, it is possible to improve the sorting performance by the grain guide plate 43 more effectively.

3, 5, and 9, the axial direction of the second processing cylinder 11 and the axial direction of the barrel 20 provided above the sorting apparatus are orthogonal in plan view. In relation to this, the right side when viewed from the front of the second processing mechanism 10 is approximately left beveled downward of the barrel axial center G when viewed from the front.

This is because the crimp net 31 arranged below the barrel 20 has a shape along the side shape of the barrel 20 when viewed from the front, and thus the center of the shaft 20 of the barrel 20 when viewed from the front. In the third upper limit S3, the horizontal distance between the right end and the shaft center of the barrel 20 can be configured to be shorter than the radius of the barrel 20 when viewed from the front of the second treatment mechanism. The mechanism is as close as possible to the shaft center of the barrel 20.

And the following two effects are acquired by the above structure.

First, as the first effect, the second processing mechanism 10 can be as close as possible to the barrel 20, so that the horizontal space occupied by the barrel 20 and the second processing mechanism 10 can be made compact. The apparatus 1 and the threshing apparatus 9 can be made compact.

Next, as a second effect, the outlet 42 provided on the lower right side when viewed from the front of the second processing mechanism 10 can be configured at a position close to the center position when viewed from the front of the sorting apparatus 1. , The second object falling from the discharge port 42 can be dropped in a position prone to spread in the left and right direction, that is, the position close to the center of the front feed plate 52, so that the grain layer can be made thin, No. 1 conveyor Leaving to (22) becomes easy to be performed. That is, improvement of the selection performance is intended.

Next, as shown in FIG. 6 and FIG. 10, a plurality of tooth bars 51, 51,... Are provided on the inner surface of the cylinder 45 covering the second treatment cylinder 11 of the second treatment mechanism 10. The tooth bars 51, 51, ... are provided with lead angles directed in the downstream direction.

The tooth bars 51, 51, ... have the function of removing the diameter by rubbing the second object together with the rotary teeth 44, 44, ... of the second treatment cylinder 11.

From this, in order to completely remove the diameter, the surfaces of the tooth bars 51, 51, ... and the rotary teeth 44, 44, ... are parallel to each other when viewed from the front, and the right side of the second object in the plane of FIG. It is desirable to slow down the feed in the direction. In other words, it can be said that the processing efficiency increases as long as the second processing mechanism 10 is retained.

However, when a large amount of the second article has been transferred, the treatment in the second treatment mechanism 10 is not continued, and clogging of the second treatment mechanism 10 may occur.

On the other hand, when a small amount of the second article is retained in the second treatment mechanism 10 for a long time, the second article is damaged by the rotary teeth 44, 44, ... and the toothed bars 51, 51, ..., Quality grains cannot be recovered.

Thus, one of the plurality of tooth bars 51, 51, ... is inclined to one of the tooth bars 51, 51, ... in the front-rear direction of the vertical mounting surface on the downstream side, that is, the discharge port 42 side. By having a lead angle, it was comprised so that it might become easy to flow 2nd thing downstream.

This lead angle is an angle R in the expanded view of the cylindrical body 45 of FIG. 10. The toothed bars 51 and 51 are seen in the state which expanded the cylindrical body 45, and when it sees in the plane which makes an inner side upper side. , ...) is inclined from the inlet 41 to the outlet 42 by the angle R.

In addition, the number of toothed bars 51, 51, ... which have a lead angle is arbitrarily selected, and it is suitably designed by the processing capability of the sorting apparatus 1, the 2nd processing mechanism 10, etc.

In this way, the second processing mechanism 10 can be stored in the case where there are many or small number of times, or for a period suitable for the removal of the diameter, and the performance of the second treatment mechanism 10 can be maximized.

In addition, since the second article is easily sent to the discharge port 42 side by the tooth bars 51, 51, ... having the lead angle, the second article is the second treatment mechanism 10 even when the second article is extremely small. You won't get stuck inside.

Next, another example of the configuration of the second processing mechanism will be described.

In addition, about the drive transmission structure to the 2nd processing mechanism 10 in this embodiment, as shown to FIG. 11 and FIG. 12, the drive from the engine which is a drive source is an output shaft, a gear case, the 1st conveyor 22, 2, and FIG. The second conveying conveyor 14 is transmitted to the second reducing conveyor 14 through the burner, etc., and is configured to be transferred from the end of the second reducing conveyor 14 to the second processing mechanism 10, and the second reducing conveyor ( The bevel gear 71 is installed at the end of the conveyor drive shaft 70 of 14), the power is transmitted to the drive shaft 11a through the sprocket 72, the chain 73, and the second processing cylinder 11 is rotated. It is a configuration. In addition, the drive transmission configuration may be the configuration (the same configuration as the skeleton diagram shown in FIG. 4) in the above-described embodiment. As a result, the conveyor drive shaft of the No. 2 reduction conveyor 14 and the No. 2 reduction processing cylinder 11 are accelerated and transmitted. In detail, the drive transmission is performed in the configuration of "sprocket 72-> chain 73-> sprocket 72a." (The Skeleton diagram shown in FIG. 13.)

Next, the control valve 63 which becomes a main part in the 2nd processing mechanism in this Example is demonstrated using FIG. 11 and FIG.

The control valve 63 is installed on the inner surface of the cylinder 45 constituting the outer frame of the second treatment mechanism 10 below the inlet 41, and controls the conveying speed of the second object in the second treatment mechanism 10. To adjust.

The control valve 63 is composed of a valve portion formed at right angles to the drive shaft 11a and a fixing portion formed of a surface disposed at a right angle with the valve portion for fixing to the cylinder 45. The rotating part 75 is provided with the support part 76 in the lower part. In the said support part 76, the control valve 63 and the cylinder 45 are pivoted by fixing means, such as a bolt, under the control valve 63. As shown in FIG. For example, a bolt hole is formed in the lower part of the control valve 63 and the cylinder 45, and the bolt 76a is inserted into the bolt hole from the inside of the cylinder 45, and the nut 76b from the outside of the cylinder 45. It can be fixed by fastening.

In the rotating portion 75, a bolt hole is formed in the upper portion of the fixed portion of the control valve 63. On the other hand, an arc-shaped long hole 45a around the bolt 76a is formed in the cylinder 45, a bolt 75a is inserted through the long hole 45a, and the bolt 75a is formed from the inside of the cylinder 45. ), The bolt 75a is projected on the outer surface of the cylinder 45, and the control valve 63 and the bolt 75a are fixed with the lock knob 65.

The control valve 63 is provided in plurality, connected by a connecting lever 64 serving as a connecting means, and the angle can be changed. That is, the connecting lever 64 is disposed on the outer surface of the cylinder 45, and the connecting lever 64 is formed with a plurality of bolt holes 64a, 64a, 64a at regular intervals. The bolts 75a, 75a, 75a protruding from the inner surface of the cylinder 45 are inserted through the bolt holes 64a, 64a, 64a, and fastened to the lock knobs 65, 65, 65 from the outside of the cylinder 45. The control valves 63, 63, 63 are fixed to the cylinder 45 via the connecting lever 64.

In this embodiment, three control valves 63, three bolt holes 64a of the connecting lever 64, and three lock knobs 65 are arranged, but the number is not limited.

With such a configuration, since the bolt 76a of the support portion 76 becomes the rotation point and the control valve 63 rotates around the bolt 76a, the angle of the control valve 63 can be adjusted. Further, since the plurality of control valves 63 are connected by the connecting lever 64, the plurality of control valves 63 can be inclined at the same angle at the same time by moving the connecting lever 64. Moreover, the long hole 45a can be blocked by the connecting lever 64, and the fall of a grain can be prevented.

In this way, when the angle of the control valve 63 is changed, the conveyance speed of the 2nd thing in 2nd processing mechanism can be changed.

For example, in a rice or barley mowing operation without a diameter, the second part inside the cylinder 45 can be quickly sent out by inclining the upper portion of the control valve 63 toward the inlet 41. It can eliminate water damage. On the other hand, in the case of rice having a large diameter, the upper part of the control valve 63 is inclined toward the discharge port 42, so that the second object is kept in the cylinder 45 for a long time, and the second object is rubbed to remove the diameter and improve the selectivity.

And the operation | movement which changes the angle of this control valve 63 can be performed easily. That is, the second treatment mechanism 10 arranges the second treatment cylinder 11 below the front end of the second reduction conveyor 14, and the second treatment mechanism 10 is the rear side of the grain tank, that is, the front side. As seen from the right side of the grain tank is located on the left side of the sorting device (1), by opening the grain tank 12, the second treatment mechanism (10) can be maintained and maintained, and the control of the control valve (63) is easy. It can be done.

In addition, as shown in FIG. 14, the center line (the cylinder 45 and the axial center line of the drive shaft 11a) of the 2nd processing mechanism 10 is arrange | positioned so that the exit side may descend by the angle A1 from a horizontal line. This angle A1 should just be an angle which can encourage discharge | emission, and does not make it the sharp angle which falls naturally. By disposing the No. 2 treatment mechanism 10 in this way, the discharge port 42 is lowered, and the second object inside the cylinder 45 is easily discharged from the discharge port 42, and the second object is the cylinder 45 at the end of the work. It can be prevented from remaining inside. Moreover, since the cylinder 45 is inclined, cleaning etc. will become easy.

In addition, when the tooth bar 51 is viewed from the side, it is arrange | positioned so that it may not be located in the lowest part of the cylinder 45. FIG. That is, when the tooth bar 51 is in the bottom part of the cylinder 45, a 2nd thing will be clogged by the tooth bar 51, and a 2nd thing will remain in the cylinder 45 inside easily. Therefore, as shown in FIG. 15, in the lower inner part of the cylinder 45, the gear bar 51 is arrange | positioned by the distance of B1, and while the vertical line passing through the center of the drive shaft 11a, and the cylinder 45 is carried out. The gear bar 51 is arrange | positioned away from the position which intersects inside, and the gear bar 51 is not arrange | positioned in the bottom vicinity.

By setting it as such a structure, 2nd thing is hard to remain in the inside of the cylinder 45, and cleaning etc. are easy to perform.

Moreover, in order to make cleaning of the inside of the cylinder 45 easy, the toothed bar 51 was set as the structure which can be removed or opened and closed.

As shown in FIG. 16, the rotating part 68 is arrange | positioned under the cylinder 45 to the cylinder 45, and the separating part 67 is arrange | positioned above the cylinder 45. As shown in FIG.

The rotating part 68 is comprised from the toothed bars 51 and 51, a part of the cylinder 45, the rotating shaft 66a, and the attachment part 66b.

A part of the rotating part 68 is provided with the rotating shaft 66a, and the rotating part 68 rotates about the rotating shaft 66a. The rotating plate 45b is fixed to the outer surface of the cylinder 45 by fixing means such as a bolt, and the rotating shaft 66a is fixed to the rotating plate 45b.

The attachment part 66b is arrange | positioned at the other end of the rotating part 68. As shown in FIG. The attachment portion 66b is detachably fixed to the attachment portion 45c protruding from the outer surface of the cylinder 45 by fixing means such as bolts and nuts.

When the bolt of the attaching part 66b is removed, the rotating part 68 rotates about the rotating shaft 66a.

The separation part 67 is comprised from the toothed bars 51 and 51, a part of cylinder 45, and attachment parts 67a and 67a.

Attaching portions 67a and 67a are provided at both ends of the separating portion 67. The attachment portions 67a and 67a are detachably fixed to attachment plates 45d and 45d protruding from the outer surface of the cylinder 45 by fixing means such as bolts and nuts.

When the bolts of the attachment portions 67a and 67a are removed, the separation portion 67 can be easily removed.

In addition, since the second processing mechanism 10 is provided in parallel to the grain tank 12 inside the gas, the second processing mechanism 10 can be repaired and managed by opening the grain tank 12 out of the gas. The rotation of the rotary part 68 and the cleaning operation which separated the separation part 67 can be performed easily.

In this way, the inside of the cylinder 45 can be easily cleaned by placing the second processing mechanism 10 on the back side of the grain tank, that is, on the left side of the sorting device 1 on the right side of the grain tank when viewed from the front. In addition, the maintenance management inside the cylinder 45 can also be made excellent.

Moreover, as shown in FIG. 17, the support arm 46a is provided so that it may protrude from the inner side surface of the left end part 69 of the cylinder 45, and it pivots the left end part of the drive shaft 11a with the said support arm 46a. In addition, by forming the opening 47 as a triangular frame body when the support arm 46a is viewed from the side, the inside of the cylinder 45 and the air supply chamber 122 are communicated. The opening on the left side of the cylinder 45 is formed very small (the cylinder 45 is not closed by the support arm 46a.)

In such a configuration, even when an excessive number of two objects is introduced into the cylinder 45, the opening 47 as the entire cylinder 45 is formed wide by the configuration of the opening 47, so that the left side of the cylinder 45 is formed. The second object can be inserted into the feeding chamber 122 from the entire opening (including the opening 47), and the cylinder 45 is not blocked.

Moreover, even if it is the structure supported by one spoke 85 like the support arm 46b shown in FIG. 17, the effect similar to the above can be acquired.

Next, the configuration in which the opening degree of the sorting body 55 of the swing selector 125 is automatically adjusted in accordance with the threshing throughput in the threshing apparatus 9 of the combine according to the present invention will be described in detail. In this embodiment, however, the threshing treatment amount is configured to be detected by the amount of straw discharged.

Moreover, in the Example shown below, the 1st form and 2nd form are proposed as a structure of opening degree control of the sorting body 55. As shown in FIG.

Chaff wires 142 and shutter wires 143 are connected to the shutter levers 141 for adjusting the opening degrees of 139 (FIG. 23) and 140, respectively, and the other side of the chain guide of the straw straw discharge chain 114 ( 144), the gap between the selection body 55 is changed large and small by the large and small amount of rice straw discharged, and also based on the increase and decrease of the grain flow rate on the selection body 55 detected by the selection flow rate sensor 172. The drive control of the motor 157 is performed so that the opening degree correction of the sorting body 55 adjusted to the set opening degree is performed. That is, the opening degree of the sorting body 55 is adjusted by the controller by changing the opening degree of the sorting body 55 by a mechanical structure, and the opening degree of the sorting body 55 is controlled.

As mentioned above, since a 2nd form adds the process of opening correction to a 1st form, it demonstrates about a 2nd form in this Example, and abbreviate | omits description about a 1st form.

Is installed vertically, the detection plate 146 is in contact with the detection link 145, the detection arm 147 is linked to the detection plate 146. Thus, when the straw guide discharges, the chain guide 144 fluctuates up and down, and when the detection arm 147 rotates around the arm axis 148 to pull the shutter wire 143, the shutter lever shaft ( The opening of the air intake ports 151 and 152 on the right side of the rosin fan 131 and the air opening 25 which are closed by the fan shutters 139 and 140 by rotating the shutter lever 141 counterclockwise around 150. It is configured to make large.

In addition, when the chaff wire 142 is pulled, the chaperber 138 is rotated counterclockwise around the lever shaft 149 to support the lower ends of the right and left ends of the sorting body 55. When the movable plate 153 is moved to increase the angle of inclination of each of the chaff pins 154, 154, ... constituting the sorting body 55, the opening degree of the sorting body 55 is increased to provide When the amount of falling out is increased and the inclination angles of the chaff pins 154, 154, ... are made smaller (down), the opening degree of the sorting body 55 is made small so as to reduce the amount of missing grains.

In addition, the outer 142a of the chaperber 138 side of the chaff wire 142 is supported by the wire bracket 156 of the switching lever 155 which is rotatable about the lever shaft 149 and the chaff The switching lever 155 is interlocked with the swing lever 159 and the switching wire 160 at the tip of the cylinder arm 158a of the opening adjustment cylinder 158 operated by the opening motor 157, and the cylinder 158 When the switching lever 155 swings about the lever shaft 149 by the forward and backward driving, the outer ring 142a of the chaff wire 142 is moved to adjust the opening degree of the sorting body 55. have.

The chaff lever 138, the switching lever 155 and the cylinder 158 are attached to the base dies 162 and 163 fixed to the outer wall of the threshing side plate 161, respectively, and the base die 162 and the switching lever ( The return springs 164 and 165 between the 155 and the chaver lever 138 and the switching lever 155, respectively, and at the one end of the outer 160a of the switching wire 160. 162 is attached to the wire bracket 167 of the attachment die 166 that fixes the other end side of the outer 160a to the base die 163. The arm shaft 170 in the middle of the rocking arm 159 is pivotally supported by the bearing 169 of the bearing plate 168 fixed to the attachment die 166, and at the same time, one end of the rocking arm 159 is provided. When the other end side of the switching wire 160 is connected to the side and the other end side of the swinging arm 59 is connected to the front end of the cylinder arm 158a to swing the cylinder arm 158a forward and backward, The switching lever 155 is rotated by pulling or loosening the switching wire 160 through 159. Reference numeral 171 denotes a chaff position sensor which detects a moving position of the chaverber 138.

Then, a potentiometer sorting flow rate sensor 172 for detecting the hydraulic pressure of the grains on the sorting body 55 is installed above the stage at the time of transfer of the sorting body 55, and the grain flow rate on the sorting body 55 is increased or decreased. Based on this, the drive control of the motor 157 is performed to correct the opening degree of the sorting body 55 which is adjusted to the set opening degree.

As shown in FIGS. 28 to 30, the sorting flow sensor 172 is an inlet side plate 174 of the side plate 173 of the rosin port No. 2 processing cylinder 21 installed in parallel from the right side of the barrel 20 to the rear side. At the same time, the second treatment 23 of the second conveyor 23 is placed in the vicinity of the second reduction exit 175 which is reduced to the swing selector 125. The bolt 177 is attached to the fixed mounting plate 176 of the side plate 173 to attach the sensor die 178 to the left and right positions, and the potentiometer 179 is fixed to the sensor die 178. The door-type mater attachment plate 180 is attached to the door mate mounting plate 180 so that the up and down position can be adjusted. Then, the front inclined detection plate 182, which is swingably fixed to the mater shaft 179a of the potentiometer 179, is directed in the flow of grain including the wind on the sorting body 55, and the detection plate 182. ), The grain flow rate on the sorting body 55 is detected by the hydraulic pressure of the grains received in the c).

In addition, the sorting flow sensor 172 is provided with one vertical return piece 183 having a lower portion formed on the weight 183a at a rear position of the front detection plate 182, and the detection plate from the mater shaft 179a. (182) The distance L2 from the mater shaft 179a to the bottom end of the return piece 183 is set small with respect to the distance L1 to the bottom end, and the flow of grain is acted only on the detection plate 182 to return the piece. It is provided so as not to act on 183, and this detection precision is improved and the detection plate 182 is returned to an initial position by the weight of the said return piece 183 at the time of stopping grain flow.

As shown in Figs. 21 and 22, the rice barley changeover switch 184 is configured to switch the standard position of the degree of selection body 55 by the varieties of rice and barley, and in the case of barley selection Offset the standard position slightly to the closed side.

In addition, the correction selection dial 185 is configured to switch the standard position of the selector 55 by a large number of wet materials or small diameters, and closes in the case of wet materials to the open side. Offset to the side.

The rice barley switching switch 184 and the correction selection adjusting dial 185 are provided in an operation panel (not shown) installed in the driving operation unit 119.

21 and 22, the crest end sensor 187 for attaching to the rear side position of the pull case 26 of the mowing device 8 and detecting the length of the crest end to be mowed, and the operation unit 119 A harvesting switch 189 for detecting the breaking of the harvesting clutch by the work clutch lever 188, a transport chain clutch 190 for stopping the driving of the transport chain 7 at the transport end of the transport chain 7, The chaff outer sensor 192 which detects the operation position of the reversing quick switch 191 which changes the mowing device 8 from vehicle speed tuning to constant rotational drive, and the switching lever 155 operated by the opening adjustment cylinder 158. ), A vehicle speed sensor 193 installed in the mission case of the main body and detecting the vehicle speed, the chaff position sensor 171, and a controller 194 for input connection to the sorting flow sensor 172. Output the controller 194 to the motor drive circuit 199 of the chaff opening motor 157 Group chaff opening is configured to perform drive control of the motor 157.

When the sorting body 55 configured as described above changes the opening degree of the sorting body 55 by mechanical control by the detection arm 147 and the chaff wire 142 for detecting the amount of straw straw, the stroke of the chaff wire 142 is changed. It is comprised so that opening degree of the sorting body 55 may change according to (pull amount).

In the conventional structure shown in FIG. 39, the detection arm 147 ′ is relatively at a right angle relative to the detection plate 146, and the detection plate 146 and the detection arm 147 ′ maintain a constant angle. It was comprised so that it may rotate around the female axis 148 in a state. Hereinafter, this structure is described as "type B."

In Type B described above, as shown in FIG. 31, the amount of change of the stroke 197 of the chaff wire 142 is constant with respect to the amount of rice straw discharged, and as shown in FIG. 32, the opening degree 197a of the selection body 55 is the amount of rice straw discharged. Is proportional to However, in the threshing machine having a large geological capacity, the area of the sorting body 55 is also expanded to improve the processing capacity of the threshing, and the opening degree of the sorting body 55 is larger than necessary at the stage where the amount of threshing is small. It is a problem that the screening ability of the hard ribs is reduced.

Therefore, in the configuration according to the present invention, as shown in Fig. 31, the shape of the detection arm 147 is determined so that the amount of change in the stroke 198 of the chaff wire 142 with respect to the amount of straw straw discharged is increased. That is, as the amount of straw straw discharged increases and the throughput increases, the stroke of the chaff wire 142 increases nonlinearly, that is, parabolic, and as shown in FIG. 32, the amount of straw straw discharged increases the opening degree of the selector 55 ( The amount of change in 198a) is greatly increased compared to the case where the amount of rice straw discharged is small.

In detail, as shown in FIG. 33, the arm axis 148 which is the rotation center of the detection plate 146, and the chap wire 142 connected to the detection arm 147 in the state which the opening degree of the selection body 55 is minimum is shown. The arm axis 148, the detection arm 147, the chaff wire 142 and the wire bracket 195 are positioned approximately in a straight line by changing the length direction of the detection arm 147 on a straight line connecting the wire bracket 195. I'm trying to. Hereinafter, this structure is described as "type A".

In the type B, the detection arm 147 'is formed of a part of the material, and two wires of the chaff wire 142 and the chap wire 143 are connected to the part of the material. Since the rotational position of the detection arm 147 in which the shutter wire 143 is in the same straight line exists, the detection arm 147 is comprised by two members so that wires may not interfere.

In Type A, when the amount of straw discharged is increased, the orbit indicated by the arrow 201 of FIG. 34 is drawn, and the detection plate 146 rotates around the arm axis 148. As a result, the detection arm 147 moves the arrow 202. The trajectory shown in the figure is drawn and rotated about the female axis 148. When the detection arm 147 draws such a trajectory, when the rotation angle of the detection arm 147 increases constantly, when the amount of straw straw discharged is large, the chaff wire 142 and the shutter wire 143 are compared with when the amount of straw straw discharged is small. The amount of change in the stroke increases. In Type A, this tendency is remarkable compared to Type B. As the straw straw discharge amount increases, the stroke of the chaff wire 142 increases nonlinearly, and as the straw straw discharge amount increases, the amount of change in the opening degree of the selector 55 is increased. Significant increase compared to low emissions. In this type A, a simple structure and good and reliable control can be performed, contributing to the improvement of the transfer performance.

In addition, when converting the structure of Type B into Type A, it is only necessary to change the position of the wire bracket 195 by replacing the detection arm 147, so that the structure can be changed into a structure that can obtain good screening performance at a relatively low cost. have.

In the shutter wire 143 connected to the detection arm 147 similarly to the chaff wire 142 of type A, the stroke of the shutter wire 143 increases nonlinearly as the amount of straw straw is increased. As the amount of rice straw discharge increases, the amount of change in the opening degree of the shutters 139 and 140 becomes larger than that when the rice straw discharge amount is small, and the amount of blowing according to the threshing processing amount can be set.

In addition, in the above-described configuration, the chaff wire 142 is connected to the chaff lever 138 to change the opening degree of the sorting body 55 by mechanical control, thereby opening the opening degree by the switching lever 155 connected to the chaff opening motor 157. Although fine adjustment is made, it is also possible to adjust the stroke of the chaff wire 142 by the chaff opening motor 157 controlled by the controller 194, which is shown below as a second embodiment.

35 and 36, a chap that is an actuator for changing the basic angle of the selector 55 near the wire bracket 195 of the chap wire 142 connected to the detection arm 147 ′ which detects rice straw discharge amount. An opening motor 157 is provided to directly connect the cylinder arm 168a and the wire bracket 195 of the opening adjustment cylinder 158 that are expanded and driven by the chaff opening motor 157. Then, the controller 194 calculates the appropriate opening degree of the sorting body 55 based on information from each sensor such as the chapping position sensor 171 or the sorting flow sensor 172, and then the motor of the chaff opening motor 157. The controller 194 is brought into contact with the driving circuit 199 to drive control of the chaff opening motor 157 to expand and contract the opening adjustment cylinder 158.

Therefore, the strokes of the chaff wire 142 and the shutter wire 143 are finely adjusted by adjusting the position of the wire bracket 195 fixed to the cylinder arm 158a of the opening adjustment cylinder 158.

In the above-described configuration, compared to the configuration in which the opening degree of the sorting body 55 is changed to the chaver lever 138, and the opening degree is slightly adjusted by the switching lever 55, the operator of the chaver lever 138 is 2 Since control to the chaff wire 142 which reduces to one at a point and pulls the chaperber 138 is performed near the wire bracket 195, the improvement of control precision is anticipated. Since the switching lever 155 does not need to adjust the opening degree of the selector 55, the switching wire 160 connecting the switching lever 155 and the cylinder arm 158a of the opening adjustment cylinder 158 and The member around it becomes unnecessary, and the number of component parts can be reduced, which is excellent in terms of simplifying the assembly process and reducing the cost.

According to the second embodiment described above, by setting the controller 194, the wire stroke with respect to rice straw discharge amount can be changed as shown in the first embodiment (198 in FIG. 31). Further, as shown in Type C 210a of FIG. 38, the number of single or plural reference straw discharges n1, n2, ... is determined in advance, and the amount of straw straw discharged until the reference straw discharges n1, n2, ... are reached. It is also possible to control so that the wire stroke with respect to the wire stroke increases linearly, and the amount of deflection of the wire stroke increases with reference to the standard straw straw discharge amounts n1, n2, .... At this time, the opening degree (210 of FIG. 38) of the selector 55 with respect to rice straw discharge amount also increases with the change of the opening degree based on the standard straw straw discharge amounts n1, n2, ..., and the change amount is the standard straw straw discharge amount n1, In addition to enlarging n2, ...) as a boundary, the amount of change can be made zero, and the opening degree of the selector 55 can also be made a section of the amount of straw straw discharged. Further, more precise control is expected by increasing the number of reference straw discharge amounts n1, n2, .... In addition, it is preferable that the form of change of the wire stroke mentioned above is more optimal according to the capability and form of a combine.

Incidentally, in the present embodiment, the straw straw discharge amount is detected from the straw straw discharge amount conveyed by the straw straw discharge chain. However, the threshing throughput detection method is not limited to this, for example, by the transfer chain 7. The threshing throughput can be detected by knowing the amount of the crests to be conveyed and the throughput on the swing selection mechanism 125.

Next, the opening degree of the sorting body is automatically adjusted in accordance with the increase and decrease of the threshing processing amount, and the opening degree adjustment is performed only when the threshing processing amount is larger than a predetermined value, and the opening degree adjustment configured to be able to change the predetermined value is performed. The mechanism will be described with reference to FIGS. 22 to 24 and 40 to 42.

As described above, in the configuration shown in Figs. 22 to 24, the amount of straw discharge (throttle processing amount) is determined by electrical control, that is, correction of the chapel 155 by the controller 194 (chap opening degree motor 157). The opening degree adjustment is made only when the value is larger than the value, and the predetermined value can be changed again.

40 or 41, on the other hand, when the detection link 145 acts on the detection plate 146 by mechanical control, that is, by mechanically adjusting the distance between the detection link 145 and the detection plate 146. By changing the discharge | emission required until now, it is set as the structure which delays the timing of adjustment which increases the opening degree of the selection body 55.

Here, "the opening degree adjustment of the sorting body is performed only when the threshing processing amount is more than a predetermined value" means that the sorting body is only when the threshing processing amount is larger than the throughput 302 as shown in the curve 301 shown in FIG. Means that the degree of change of the throughput 302 is changeable. In addition, the straight line 300 in Fig. 42 shows a case in which the straw straw discharge amount has a large opening in proportion to the increase in the straw straw discharge amount at a zero stage (for example, the conventional example shown in Fig. 39). The opening degree change characteristic is shown.

The mechanical control structure shown in FIG. 40 and FIG. 41 is demonstrated concretely.

The bracket 241 is disposed near the detection arm 147, the stay 244 is protruded from the bracket 241, and the stopper bolt 242 is screwed into the stay 244 to regulate the nut. The stopper bolt 242 is positioned with respect to the stay 244 by 243. A stopper portion 245 is formed at the tip of the stopper bolt 242 so as to be in contact with the side surface of the detection arm 147.

In this way, the adjustment length 79 is made adjustable by the screw-in insertion of the stopper bolt 242, and the contact end 77 provided in the bottom part of the detection link 145 by the change of the adjustment length 79 is carried out. ) And the contact distance 78 of the detection plate 146 can be changed.

In this configuration, increasing the adjusting length 79 increases the contact distance 78 and conversely decreasing the adjusting length 79 decreases the contact distance 78.

In the case where the contact distance 78 is increased, the amount of straw straw discharged (throw threshing throughput) required until the contact end 77 acts on the detection plate 146 as compared with the increase before the increase is required. That is, the amount of rice straw discharged (throw threshing amount) required until the opening degree adjustment of the sorting body 55 starts is required, in other words, when the amount of rice straw discharged (throw threshing amount) until the predetermined amount reaches a predetermined amount is selected. The opening degree of the sieve 55 is not adjusted.

In this way, when the amount of rice straw discharged (threshing amount) is small, the opening degree of the sorting body 55 is not increased. In other words, by keeping the minimum, it is possible to prevent local hard grains and straws having a low specific gravity from falling out of the sorting body 55, to improve the quality of the grains recovered by the first conveyor 22, and to improve the quality of these grains and straws. Can be guided to the number 2 conveyor 23 to increase the number 2 reduction amount, and the diameter treatment in the number 2 processing mechanism 10 can be performed.

In addition, with respect to the direction and the position of the stopper bolt 242 and the detection arm 147, it can be considered as shown in Fig. 40, and as shown in Fig. 41 can be considered. In the case of the configuration (type A) of FIG. 40, the amount of straw straw discharged with the parabolic increase characteristic shown in the curve 301 shown in FIG. 42 with respect to the increase in the amount of straw straw discharged after the sorting body 55 starts to adjust the opening degree. When the amount of rice straw is increased, the amount of increase in the opening amount per unit increase amount is increased, and in the configuration of FIG. 41, it is proportionally, that is, it has a characteristic of increasing linearly linearly as in the straight line 303 shown in FIG. Irrespective of the increase or decrease of rice straw discharge, the amount of increase in opening degree per unit increase of rice straw discharge is constant.

On the other hand, in the electric control configuration shown in Figs. 22 to 24, the chaff opening motor 157 is controlled by the controller 194 to resist the pulling force of the chaff wire 142 by the action of the detection link 145. By operating the switching lever 155 through the switching wire 160, the opening degree of the sorting body 55 is adjusted only when the threshing processing amount is larger than the predetermined value, and the operating amount of the chaff opening motor 157 is also adjusted. Is controlled by the controller 194 to adjust the predetermined amount by adjusting the position of the switching lever 155.

In addition, with the configuration of the above electrical control, it is also possible to adjust the throughput 302 in FIG. 42 by adjusting the correction selection adjusting dial 185 (FIG. 20).

Next, a configuration in which "selection" is appropriately performed to improve the screening capability, increases the number 2 reduction amount, and improves the quality will be described with reference to FIG.

This configuration effectively prevents sedimentation of grains, straws, etc. on the grain sieve 49 by effectively applying the sorting wind to grains, straws, etc. before exiting the sorting bodies and after exiting the sorting bodies, thereby appropriately selecting "selection". In order to increase the number of reductions by increasing the number of reductions by guiding the grains in the case of falling to the number 1 conveyor 22 and being conveyed to the grain tank 12 to the number 2 conveyor 23, It is.

That is, as shown in Figure 43, the first recovery mechanism for conveying the first article to the grain tank through the first conveyor and the grain cereal conveyor, and the second article to the second treatment mechanism through the second conveyor and the second reduction conveyor, After removing the diameter and the like by the No. 2 treatment mechanism, the No. 2 water reduction cycle mechanism which is re-introduced into the sorting unit again, the balloon staring mechanism composed of one or a plurality of fans, the swing screening mechanism and the first conveyor flows upward. It is provided with the air flow path which flows a selection wind from front to back.

Moreover, the inclination of the front and back height is comprised in the 1st grain plate which guides a grain to the said 1st conveyor, and the air path which guides the said sorting wind which collides with the said 1st grain plate to the rear inclination direction is formed.

Hereinafter, the detail, effect | action, and effect of the said structure are explained in full detail.

As shown in Fig. 43, the first collecting mechanism is composed of a first conveyor 22, a grain cereal conveyor 13, and a grain tank 12 (Fig. 1).

Moreover, the 2nd reduction cycle mechanism is comprised by the 2nd conveyor 23, the 2nd reduction conveyor 14, and the 2nd processing mechanism 10. As shown in FIG.

In addition, the balloon-specific mechanism is composed of a rosin pan 131, which is a free pan, and a tuyere 25, which is a main blower.

In addition, the swing selection mechanism is carried out in order from the front feed plate 52 → the rear feed plate 53 → the sorting body 55, the fixed chap part 57 → the grained plate 58, and the grain sheave 49. It is formed horizontally, 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 ballooning mechanism is passed.

As for the air path, as shown in Fig. 43, the space between the front feed plate 52 and the rear feed plate 53 is defined as the first air path 401, and the first air path 401 is provided with a rosin fan 131. The 1st sorting wind 501 which arises by this flows.

Since the first air passage 401 is formed by the front feed plate 52 and the rear feed plate 53 which are installed substantially horizontally, the first sorting wind 501 flows from the front to the rear, and at the same time, the suction fan 30 In addition to the suction force of both), it acts to guide the grain, rice straw, etc. which fall out from the said crimp nets 31 and 21a more rearward.

In addition, a space between the rear feed plate 53 and the grain plate 58 is used as the second air path 402, and the second wind 502 generated by the air vent 25 is formed in the second air path 402. It is supposed to flow.

Since the second air passage 402 is formed by the rear feed plate 53 and the grain plate 58 which are installed substantially horizontally, the second sorting wind 502 flows from the front to the rear, and at the same time, the suction fan 30 In addition to all the suction force, and acts to guide the grain, rice straw, etc. falling from the sorting body 55 to the rear. In addition, since the portion 502a of the second sorting wind 502 flows upwardly between the sorting bodies 55, it may prevent the inflow from the sorting bodies 55 such as small grains and rice straws having a small specific gravity. Works.

In addition, a second space 503 generated by the air vents 25 is formed in the third air path 403 in the lower space from the grained grain plate 58 and the sorting body 55. It shall flow. Further, in the third air path 403, a triangular wind direction guide 525 is provided at a position at the same height as the center of rotation of the air outlet 25 and at the same height as the rotation center of the air outlet 25. The wind direction guide 525 serves to control the flow rate and direction of the third sorting wind 503, and in this embodiment, the third sorting wind 503, the two flows 503b, 503c is formed, and the upward 3rd sorting wind 503b flows toward a rear inclination upward, and the downward 3rd sorting wind 503c flows toward a rear inclination downward.

In addition, although the shape of the said wind direction guide 525 is not limited to a substantially triangular cross section, the cross section may be circular arc shape, plate shape, etc. may be sufficient as it. Incidentally, the inclination of the side surface of the wind direction guide 525 can be arbitrarily adjusted so that fine adjustment of the third sorting wind 503 can be made possible.

In addition, the above-mentioned third sorting winds 503b and 503c flow from the front to the rear and collide with the first curved plate 410 in a state in which both the suction force with the suction fan 30 and the wind loss are eliminated.

The first grain plate 410 is disposed at the rear end of the grain sheave 49 from the first conveyor 22 toward the inclined rear, and the third air passage 403 and the second conveyor 23 It is divided into a space 405 to be disposed. Here, the inclination of the first curved plate 410 is the front and rear high (approximately 30 degrees in this embodiment). The inclination of the first curved plate 410 is changed so that the wind direction of the third sorting winds 503b and 503c is inclined upward.

Due to the change in the wind direction as described above, air flow 503a flowing through the sorting body 55 from the first conveyor 22 and flowing into the suction fan 30 is generated on the upper surface of the first grain plate 410. Air flow 503a passes through the grain sheave 49 and blows up the grain, straw, etc. which are about to fall to the conveyor 1, and the first conveyor 22, such as a small-diameter grain, a water-cut, straw, etc. with a small specific gravity. Acts to hinder ingress into

In addition, with respect to the downward third sorting wind 503c, when the wind strikes the first curved plate 410, a part of the wind direction is directed downward, and effectively the grain attached to the surface of the first curved plate 410 is effectively 1. The burner conveyor 22 is guided.

As described above, in the three kinds of sorting winds 501, 502, and 503, the wind direction is horizontally aligned by the respective air passages 401, 402, and 403 in the first conveyor. Therefore, the wind speed is secured in a wide range from the front part to the rear part of the sorting device, and the sorting ability of grains and straws falling from the crimp nets 31 and 31a is improved.

In the first and second sorting winds 501 and 502, the grain sheave 49, the sorting body, and the like, which are horizontal grains, water cuttings, straws, etc., in which the wind direction is horizontally aligned, and the specific gravity is lighter, above the first conveyor. 55) guides the rear and the second conveyor 23 before implantation, thereby appropriately performing "sorting" and at the same time the grains, water cuttings, straws, etc. in the grains implanted and deposited on the grain sheave 49. The content rate is reduced, and fine grains are recovered.

In the third sorting wind 503, the wind direction is horizontally aligned above No. 1 conveyor, and the grain, grain cutting, rice straw, etc. having a small specific gravity pass through the grain sieve 49 to No. 1 conveyor 22. While preventing the inflow, as a result, the amount of grain, grain size, etc. guided to the second conveyor 23 is increased, thereby increasing the amount of grain, grain size, etc., for which the diameter treatment is performed by the second reduction cycle. You can.

As described above, even when the threshing treatment amount is increased, the inflow to No. 1 conveyor 22 such as a grain size, water cutting, rice straw, etc. is prevented, and these are removed and reselected by the No. 2 reduction cycle. As a result, the quality of the grains finally collected in the grain tank 12 can be improved, and at the same time, the reduction in the amount of grains collected by the selection loss can be prevented.

Next, in connection with the adjustment of the opening degree of the said sorting body, the structure which performs "selection" appropriately and improves a sorting ability, increases the 2nd reduction amount, and aims at the improvement of quality is demonstrated.

In this configuration, when the amount of straw straw discharged (throw threshing amount) is large, and the opening degree of the sorting body 55 is increased, and the amount of extraction from the sorting body is increased, the sorting wind is effectively applied to the grains and straws before removing the sorting body and after being removed. This function prevents grain, straw, etc. from being deposited on the grain sieve so that "selection" can be appropriately performed. The grains when falling to the first conveyor 22 and conveyed to the grain tank 12 are divided into two. By guiding to the burner 23, the reduction amount of the number 2 is increased, and the quality is improved.

On the other hand, in the case where the amount of rice straw discharged (the threshing processing amount) is small, as described in FIGS. 31 and 32 (same as in FIGS. 37, 38, and 42), the opening degree of the sorting body 55 is small. The advantage of being retained (improved change characteristics) is minimized, the amount of falling out to the first conveyor 22 is reduced very much, and the second conveyor 23 is guided to improve the quality.

In addition, by automatically adjusting the opening degree of the sorting body in accordance with the threshing processing amount, it is possible to improve the sorting ability by setting the amount of missing from the optimal sorting body for the predetermined threshing processing amount.

That is, as shown in Figure 43, the sorting device is a number 1 recovery mechanism for conveying the first water to the grain tank through the first conveyor and the grain cereal conveyor, and the second processor through the second conveyor and the second reduction conveyor The second water reduction cycle mechanism, which is sent to the ward and removes the diameter and the like by the second treatment mechanism, and then re-injected into the sorting unit, a balloon-specific mechanism composed of one or a plurality of fans, and automatically according to the increase and decrease of threshing throughput The opening degree adjustment mechanism which adjusts the opening degree of a sorting body, a rocking | swinging selection mechanism, and the air path which flows the sorting wind which flows over the No. 1 conveyor from front to back are provided.

As shown in FIG. 43, the opening degree adjustment mechanism adopts the "first form of the first embodiment" in the structure of the opening degree adjustment of the sorting body 55 mentioned above, and controls the opening degree of the sorting body 55 mechanically. (The structure of FIG. 19, FIG. 20 is employ | adopted.). In addition, the above-mentioned "second embodiment of the first embodiment" including the sorting flow rate sensor 172 may be employed. This opening degree adjustment mechanism sets the opening degree of the optimum sorting body in accordance with the amount of straw discharged (threshing throughput).

The increase of the 2nd reduction amount in this structure is demonstrated below.

When the amount of rice straw discharge is large and the threshing processing amount is increased, the opening degree of the sorting body 55 is increased by the rotation of the chaperber 138, and the amount of falling out from the sorting body 55 to the grain sieve 49 is increased. In addition to this, the quantity to fall from the grain sieve 49 to the No. 1 conveyor 22 also increases.

In such a case, as described above, the inflow into the first conveyor 22 such as the local grain, the water cutting, and the straw is prevented, and the diameter removal treatment and the reselection are carried out by the second reduction cycle. The quality of the grains collected by the grain tank 12 can be improved, and a reduction in the amount of grains collected by the sorting loss can be prevented.

On the other hand, when the amount of rice straw discharge is small and the threshing processing amount is small, the opening degree of the sorting body 55 is reduced by the rotation of the chaperber 138.

Here, about the opening degree of the sorting body 55 in the case where the rice straw discharge | emission amount (threshing processing amount) is small, also in the case of the 2nd Example shown in FIG. 30 and FIG. 31 (FIG. 37 and FIG. 38, FIG. 40 and FIG. The same applies to the configuration shown in Fig. 41, particularly in the case of the closed state (the increase in the amount of opening of the selector with respect to the increase in the amount of straw straw discharged) and the amount of straw straw discharge (the threshing throughput) is small. Lips, water cuttings, rice straws, etc., are in a difficult state to fall from the sorting body 55.

As the amount of falling from the sorting body 55 to the grain sieve 49 decreases, the grain or rice straw which floated in the air paths 401 and 402 or was implanted on the sorting body 55 and the grain sieve 49 was made. The back is guided to the fixed chap part 57 by the sorting winds 501 and 502, and the second reduction amount is increased by falling to the second conveyor 23.

Thus, in addition to conveyance to the rear part of grain, straw, etc. by action of the sorting wind, the conversion characteristic of the opening degree of the sorting body 55 mentioned above was improved (FIG. 31, 32, 37, 38, 42) ), It is possible to reliably increase the second reduction amount even when the amount of rice straw discharged (threshing throughput) is small. Then, the inflow into the first conveyor 22, such as the tilling, the water cutting, and the straw, is reduced, and the grain tank 12 is finally removed by performing the diameter removing treatment and re-selection by the second reduction cycle. The quality of the grains collected at the same time can be improved, and a reduction in the amount of grains collected by the sorting loss can be prevented.

The above-described configuration, that is, the first recovery mechanism for returning the first article to the grain tank through the first conveyor and the grain cereal conveyor, and the second article to the second treatment mechanism via the second conveyor and the second reduction conveyor, After removal of the diameter and the like by the second treatment mechanism, the second reduction cycle mechanism which is re-introduced into the sorting unit, the balloon-specific mechanism composed of one or a plurality of fans, and the opening of the sorting body automatically in accordance with the increase and decrease of threshing throughput An opening degree adjustment mechanism for adjusting the pressure difference, wherein the opening degree adjustment is performed only when the threshing processing amount is larger than a predetermined value. The predetermined value is changeable, and the air passage for flowing the sorting wind flowing above the No. 1 conveyor from front to back. As a result of adopting a constitution to be provided, degreasing was carried out under the condition of a predetermined threshing throughput, and the results of comparison of the amount of local hard grains recovered by the first and second conveyors were found. Be the point of the lip that is recovered in the Bayer reached to obtain a result that is at least three times the number of the point number of ribs on the conveyor 1.

In addition, the amount of the fat grains recovered by the second conveyor is usually measured by recovering the second substance in the case of being returned to the second reduction conveyor, and the paper grains referred to here also include water cutting.

In this way, much of the grain size is recovered to the second conveyor, and the second reduction conveyor cycle is carried out to remove the diameter and finally to the first conveyor and the grain tank as a fine grain.

As mentioned above, according to the structure of this Example, the improvement of the selection | separation ability is aimed at and the improvement of the quality of the grain finally recovered to a grain tank by the increase of 2nd reduction amount is realized.
