Description

558415 A7 B7 V. Description of the invention (1) Technical field of the invention The invention relates to a selection device for a combine harvester. (Please read the precautions on the back before filling this page) It is particularly about the structure of the secondary reflow processing mechanism used to reflow the selection device, and then put it into the structure of the secondary reflow processing mechanism of the selection device. The structure of the mechanism for automatically adjusting the opening degree of the bran sieve of the shaker selection mechanism by automatically adjusting the amount of stalk discharge conveyed by the stalk discharge chain. Prior Art First, the prior art regarding the secondary return conveyor and the secondary processing mechanism will be described. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed on the previous combine harvester to send the secondary objects selected by the selection device to the secondary processing mechanism through the secondary conveyance and secondary return conveyor, and borrow the secondary treatment. After the mechanism removes the branches and the like, it returns its angle to the secondary material return cycle of the selection device. Examples of past structures are, for example, Japanese Patent (Invention Patent) No. 2 5 8 9 9 5 and Japanese Patent Publication (Invention Patent Application) Publication of Showa (later known as "Japanese Patent Application") 6 1 -021026, Japanese Patent Application Laid-Open No. 61-021027, disclosed in Japanese Utility Model Application (New Type Patent) No. 62-004935, and Japanese Patent Application No. 58-055442. All of them disclose a secondary processing mechanism in which a rotation axis is arranged parallel to the rotation axis of the threshing drum from a planar perspective. In addition, in terms of the transfer of the secondary objects from the secondary return conveyor to the secondary processing mechanism, they are all on the side of the starting end of the cylinder of the secondary processing mechanism, that is, except for -4- this paper size applies to the Chinese National Standard (CNS) A4 specifications (210X29 * 7 mm) 558415 A7 B7 V. Description of the invention (2) (Please read the precautions on the back before filling out this page) Except No. 2 5 8 9 9 6 5 of this license, it is vertical and flat Two communication holes are provided at the starting end to communicate with the secondary return conveyor. Moreover, even in Japanese Patent No. 2 5 8 9 9 6, the drive shafts of the secondary return conveyor and the secondary processing mechanism are common shafts inclined obliquely upward. Therefore, the secondary object transfer direction between the secondary return conveyor and the secondary processing mechanism is the axis direction of the cylinder of the secondary processing mechanism, which is transferred along the substantially horizontal direction or above the slope. The prior art of automatically adjusting the processing capacity of the sieve opening of the shaker selection mechanism will be described. In the conventional combine harvester, the reaping rod was moved by the threshing drum of the threshing unit, and the threshing was performed while the falling threshing grain and stem mandrel fell on the shaking selection mechanism arranged below the threshing part. In addition, when these kernels, stem shavings, and the like fall, and are transported to the bran sieve in the horizontal direction in the widthwise direction of the aforementioned shaking selection mechanism, specific gravity selection and wind selection are performed. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The bran sieve is composed of multiple bran sieves, and a sieve is arranged under the bran sieve. In addition, a wind separator for wind selection is arranged below and before the bran sieve, and a primary conveyor for conveying the selected primary object in the left-right direction and a secondary conveyor for conveying the secondary object are sequentially arranged behind the wind separator. . In this structure, it is arranged that the pupae grains leaked from the above-mentioned bran sieve and the pupae grains of the stem mandrel are used as one-time items, and are transported and stored in a shell trough by a single conveyor. The secondary objects such as objects are returned (returned) through the secondary conveyor and the secondary return conveyor. In the other direction, the wind blows light stem swarf, etc., and is exhausted from the body by the suction fan. In addition, in order to improve the selection accuracy, and the amount of 榖 is proportional, adjust 榖 -5- This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 558415 A7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs __B7 V. Description of the invention (3) The amount of grain leakage from the bran and the air volume of the wind separator. That is, the detection device installed on the stem row manuscript chain is used to detect the stem row manuscript amount, and the opening degree of the bran sieve is changed according to the stem row manuscript amount, and the air volume is selected. For example, as shown in FIG. 39, if the detection arm 1 4 7 ′ rotates with the posture change amount of the chain guide located below the row of stems, the bran sieve wire connected to the detection arm 1 4 7 ′ is borrowed. 1 4 2 The mechanical control of the so-called bran sieve opening is operated. Further, in the above-mentioned structure, the so-called "rough separation" is performed on the bran sieve by shaking and clearance, and the so-called "selection" is performed on the sieve by using the mesh of the wind and sieve produced by the wind separator. In this "rough selection", the amount of leeches and stems from the bran sieve will change as the amount of shelling treatment increases and the opening of the bran sieve changes. In the case of a small amount of decanting treatment, when the aforementioned opening degree is small, the amount of pupae, stems, etc. that are leaked from the bran sieve is small. (Flow Conveyor) performs a secondary material return cycle. Since the amount of pupae, stems, etc. from the bran sieve leakage to the sieve sieve is also small, so the floating stem manuscript is easy to borrow to select the wind to the rear. Because the "screen" formed by the mesh is also properly carried out, " "Rough selection" is carried out appropriately. Problems to be Solved by the Invention First of all, regarding the problems of the prior art of the secondary return conveyor and the secondary processing mechanism, since the transfer direction from the secondary return conveyor to the secondary processing mechanism is approximately horizontal or inclined upwards, so Secondary objects are easily blocked between the secondary return conveyor and the secondary processing mechanism. In particular, "if the length of the secondary object retention period in the secondary processing mechanism is set longer," this tendency will be stronger. (Please read the notes on the back and fill in this guide) The paper size applies to the Chinese National Standard (CNS) 8 4 specifications (210X297 mm) -6-558415 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Explanation (4) Also, “the secondary processing mechanism is transported while being processed by the rotation of the rotating teeth”, but because the speed of processing the grains in the secondary processing mechanism, that is, the processing capacity, cannot be changed according to rice, wheat, etc. The type of thing changes the processing status. Therefore, when it is set for rice use, it will damage the grains when harvesting rice or wheat without sticks, and when it is set for use with wheat, 'there is a lot of rice that cannot be removed completely. Improper branch stalks occur. Therefore, the object of the present invention is to improve the sorting performance of the sorting device, improve the accuracy of branch removal, and make the body compact. Secondly, in the prior art direction of automatically adjusting the opening degree of the bran sieve of the shaking selection mechanism according to the descaling processing amount, due to the increase in the amount of stemmed manuscripts detected by the previous structure shown in FIG. Proportionately increases the opening of the bran sieve, so the capacity is larger than the hulling machine to increase the dehulling treatment capacity and increase the area of the bran sieve. When the amount of hulls is small, the opening of the bran sieve will be larger than necessary. , Or the green stalk is cut in the middle, or the selection ability of the stem plug is reduced. Therefore, in addition to the above objects, the present invention aims to provide a structure that adjusts the opening degree of the sifted sieve to increase the opening degree of the bran sieve in a straight line without increasing the amount of stemming paper. It is further limited to the above "rough selection" and "selection". In the case of a small amount of deaeration, and in the case of a small sieve opening, the problem of "selection" is not appropriate. However, when the amount of deaeration is large In the case of the large opening, the situation is different. That is, with the increase in the amount of sieve leaked from the bran, the "selected" capsules (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ) 558415 A7 B7 V. Description of the invention (5) (Please read the notes on the back before filling out this page) • The amount of stem manuscripts etc. increased. In this way, the transfer of stem manuscripts made using the wind of winds is also hindered. 'Fat ca n’t “screen out” clams, stems, etc., and pile up on the crust sieve. The granules leaked and led to the primary conveyor. That is to say, it is impossible to increase the amount of dehydration treatment, and proper "fine selection", branch stalks, broken ears, and even stem drafts are guided to the primary conveyor, and the quality of the cymbals recovered in the chute will become poor. This situation can also be said to be the case where the stalks treated with the stalk treatment are not treated for the stalk treatment, that is, they are recovered in the trough. Therefore, in addition to the above-mentioned object, the present invention aims to provide a method of "selecting" and increasing the amount of secondary recirculation cycle (hereinafter referred to as " "Second return flow") to effectively perform stalk treatment, and seek for a structure with improved selection ability and quality. Summary of the Invention (Objective, Structure, Effect) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs First, the purpose of the present invention is to make the secondary reflow processing mechanism of the selection device of the combine harvester small and have a high secondary recirculation processing capacity. structure. Therefore, 'the present invention firstly rotates and freely stores a secondary processing cylinder in a sorting device provided with a combine harvester that has a secondary conveyor and a secondary return conveyor that transports the sorted secondary material to the sorting department. The cylinder body constitutes a secondary processing mechanism. An input port is provided on the circumferential side of the cylinder body, and the terminal opening communicating with the secondary return conveyor is opened at the input port. The size of the secondary paper is subject to the Chinese National Standard (CNS) A4 specification (210X297) 558415 A7 B7 5. Description of the invention (6) Drop it and put it into the cylinder. Thereby, the secondary material returned by the secondary conveyor is not left, and it can be put into the barrel of the secondary processing mechanism, and there is no need to worry about the secondary material blocking the terminal of the secondary conveyor. The input port is provided near one end of the cylinder of the secondary processing mechanism, and communicates with the secondary return conveyor. At the same time, a discharge port is provided at the other end of the cylinder, and the discharge port is disposed at the beginning of the selection device. With this configuration of the secondary processing mechanism, the rotating teeth and racks of the secondary processing cylinder can be effectively used as secondary objects, and the efficiency of branch removal can be improved. From a planar point of view, the axial direction of the aforementioned secondary processing cylinder is orthogonal to the axial direction of the threshing drum provided above the sorting device. As a result, the discharge port provided on the lower right side of the front view of the secondary processing mechanism can be arranged near the center position of the front view of the sorting device, so that the secondary object falling from the discharge port can be easily hit in the left-right direction. The scattered position, that is, the position near the center of the first feeding plate, can thin the granule layer, and can easily leak down to the primary conveyor. That is, improvement in sorting performance can be sought. In addition, the secondary processing cylinder is arranged orthogonally to the traveling direction of the body from a planar perspective, and the rotation direction of the secondary processing cylinder is clockwise when viewed from the left side of the traveling direction of the body. With this, when the secondary material is discharged from the discharge port, the flow of the wind generated by the secondary processing cylinder flows forward (body traveling direction), and is surely discharged in front of the first feeding plate, which can fully diffuse the secondary Material, thinning the granule layer, easy to leak towards the primary conveyor. That is, an improvement in election performance is sought. In the present invention, the control valve is additionally provided in the secondary processing mechanism, and is configured to adjust the angle of the control valve. That is, the control valve can be turned to change the secondary processing machine. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm).

Ϋ- 1 I -I-I (Please read the notes on the back before filling out this page)-Order printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs-9- 558415 Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printing A7 B7 V. Description of the invention (7) Feed rate of grains in the structure. Therefore, when harvesting rice or wheat without sticks, you can quickly send out the kernels inside the secondary processing mechanism to prevent the kernels from being damaged. Moreover, in the case of rice with many branches, by leaving the kernels in the secondary treatment mechanism for a long time and rubbing the kernels and debris, the stems can be removed and the selection rate can be improved. Furthermore, a plurality of the control valves are provided. Each control valve is connected by a connecting device, and the angle of a plurality of control valves can be changed at the same time. Therefore, by operating the link, the plural control valves can be adjusted to the same angle at one time, making adjustment easier. In the present invention, the center line of the cylinder body covering the secondary treatment cylinder in the secondary treatment mechanism is arranged so that the outlet side is inclined downward. Thereby, the inside of the barrel and the pellets and the like can be left at the end of the work, and sweeping and the like can be easily performed. In the present invention, the cylinder of the secondary processing mechanism is arranged inside the trough, and the cylinder can be reached by starting the trough. Therefore, by opening the grate groove, inspection, repair, etc. of the secondary processing mechanism can be performed, and the aforementioned control valve can be easily adjusted and cleaned. Secondly, an object of the present invention is to provide a shaking sorting mechanism that appropriately obtains a sorting effect in accordance with a descaling amount. Therefore, in the present invention, in the sorting device of a combine harvester configured to automatically adjust the opening degree of the bran sieve in the shaking selection mechanism, the amount of change in the opening degree of the bran sieve that is increased relative to the descaling treatment amount is controlled so that It becomes smaller when the amount is small, and becomes larger when the dehydration treatment amount is large. Preferably, it is controlled so that as the dehydration treatment amount increases, the parabola increases. Specifically, the structure of the bran sieve lever used to detect the dehydration treatment amount by wire connection and the bran sieve lever that operates the bran sieve opening degree. This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) _ _ ( (Please read the notes on the back before filling this page) 558415 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Industrial and Commercial Cooperatives, A7, B7 5. In the description of the invention (8), when the rotation angle of the detection arm is increased, the amount of stems is reduced. The stroke change of the bran sieve wire is often larger than that when the amount of stem manuscript is small. In this way, it is possible to further change the opening degree of the bran sieve according to the dehydration treatment amount, which helps to improve the selection ability. The amount of change in the opening degree of the bran sieve that is increased relative to the aforementioned descaling treatment amount may be further changed based on the arbitrarily set reference descaling treatment amount as a limit, and the change may be started. That is, the opening and closing of the bran sieve is kept constant until the reference dehydration treatment amount is reached. Furthermore, by appropriately setting the reference descaling treatment amount in accordance with the change in the amount of stemmed manuscripts, making finer and better changes in the sieve opening degree according to the descaling amount is helpful to improve the selection ability. An actuator that changes the opening degree of the bran sieve is further set, and the opening degree of the bran sieve is controlled by a controller that controls the momentum of the actuator. In this way, it is possible to carry out accurate control of the sieve opening degree of the bran, which can be controlled with higher precision than the mechanical control of the sieve opening degree of the bran. According to this, the sorting device of the combine harvester that automatically adjusts the opening degree of the bran sieve of the shaking sorting mechanism according to the dehydration treatment amount is constituted as described above. That is, a steel wire is connected to a detection arm for detecting the amount of dehydration and a bran sieve lever that operates the bran sieve opening degree, and is configured to support the steel wire on the body side when the bran sieve has the smallest opening. The rotation centers of the frame, the detection arm and the detection arm are located approximately on the same straight line. With this configuration, under the situation that the rotation angle of the detection arm increases and is constant, the amount of movement of the bran sieve wire when the amount of stems is large is larger than that when the amount of stems is small. The change of the sieve opening degree is more conducive to the improvement of the selection ability. In addition, because the structure is simple, the assembly process is simple.

V. Invention Description (9) In case of failure, the maintenance cost can be reduced because only broken components can be replaced. Secondly, an object of the present invention is to provide a sorting device with high efficiency in a sorting device of a combine harvester that can perform both functions of a wind sorting mechanism and a shake sorting mechanism. Therefore, the present invention is provided with a primary recovery mechanism, and transports the primary object to the chute via the primary conveyor and the stern conveyor; the secondary return circulation mechanism, which transports the secondary object through the secondary conveyor and the secondary return conveyor. Sent to the secondary processing mechanism, and after the secondary processing mechanism is used to remove branches and stems, it is again put into the selection department; the wind selection mechanism is composed of one or more fans; the selection mechanism is shaken; and the air path is moved along The selection of the wind flowing above the conveyor belt from the front to the rear. According to this configuration, by selecting different winds, the stalk grains, broken ears, stems, etc., which are floating and have small specific gravity, are implanted on the sieve sieve and bran sieve, and then guided to the rear and to The secondary conveyor is appropriately "selected", and at the same time, the contents of stalks, broken ears, stems, etc. in the seeds that are implanted, piled on the sieve, and bran sieve can be reduced, and the good quality can be recovered. grain. Moreover, it is an opening degree adjustment mechanism that automatically adjusts the opening degree of the bran sieve in the selection device of this structure according to the increase or decrease of the dehydration treatment amount, and can be closed and adjusted at will in the case of a small dehydration treatment amount. The structure is that when the amount of stem manuscripts (the amount of dewatering treatment) is small, the opening degree of the bran sieve is not large, that is, it is maintained at the minimum opening degree, which hinders the self-branches with stems and stems with a small specific gravity Under the sieve leakage, the quality of the pupae recovered by the primary conveyor can be improved, and at the same time, such stems and stems can be led to the secondary conveyor (and the secondary return flow (please read the precautions on the back first) (Fill in this page) • — Binding-The size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -12- 558415 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of invention (10) Device), increase the secondary return flow, and apply the stem treatment of the secondary processing mechanism. It can achieve the improvement of the selection ability of the selection style, and promote the increase of the amount of secondary reflow. It is formed on the primary conveyor to guide the granules, so that the first streamer plate is inclined forward, low and high, and the selected wind hitting the first streamer plate is guided to the wind path obliquely above the rear. As a result, the air flowing from the primary conveyor through the bran sieve and flowing into the suction fan is generated on the first ridge plate, and this air passes through the sieve and blows the kernels and stems that are leaking down the primary conveyor. Prevents small specific gravity branches, stubbles, stems, etc. from flowing into the primary conveyor. Therefore, the amount of stalks, stems, etc. that leads to the secondary return conveyor is increased, and the secondary return cycle is increased. The amount of stalks, stalks, etc. that are treated with branches will improve the selection ability.

Description of the invention (38) The detection arm 1 4 7 'is Too right angle position, with the detection plate 1 4 6 and the detection arm 1 4 7 maintaining a certain angle, rotate around the arm shaft 1 4 8 as the center. This structure is described below as "type B". As shown in Fig. 31, in the above type B, the change in the stroke length of the bran sieve wire 1 4 2 with respect to the amount of stem discharge is constant. As shown in Fig. 3, the opening of the bran sieve 5 5 (1 9 7 a) is proportional to the amount of stemmed manuscripts. However, in order to improve the dehydration treatment capacity, the dehydration machine with a larger capacity also expands the area of the bran sieve 5 5, which is formed at a stage where the de-aeration amount is small. The stalk is cut off on the way, or the selection ability of the shoots is low. Therefore, as shown in FIG. 31, in the structure of the present invention, in order to increase the amount of change in the stroke (1 9 8) of the bran sieve wire 1 4 2 with respect to the amount of stemmed paper, the detection arm 1 4 7 shape. That is, as the amount of stemmed manuscripts increases and the processing capacity increases, the stroke of the bran sieve wire 1 4 2 becomes non-linear, that is, it increases in a parabolic shape, compared with the case of less stemmed manuscripts. The more the sieve sieve sieve sieve sieve 55 (19 8 a) changes, the greater the amount of change. In detail, as shown in FIG. 3, in the minimum opening state of the bran sieve 55, the arm shaft 1 4 8 connected to the rotation center of the detection plate 1 4 6 and the Ying connected to the detection arm 1 4 7 Bran sieve wire 1 4 2 on the straight line of wire rack 1 9 5 facing the longitudinal direction of the detection arm 1 4 7 'arm axis 1 4 8, detection arm 1 4 7, bran screen wire 1 4 2 and wire The shelves 1 9 5 are positioned approximately in a straight line. This structure is hereinafter referred to as "type A". And, of course, the type B constitutes the detection arm 1 4 7 ′ with a component, and the bran (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm)- 41-558415 Printed by A7 B7_, Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Invention Description (39) Screen wire 1 4 2 and door wire 1 4 3 bis The wire is connected to a structure, but the type A is on the bran The screen wire 1 4 2 and the door wire 1 4 3 are located on the same straight line as the detection arm 1 4 7. Therefore, in order to prevent the wires from interfering, the detection arm 1 4 7 is composed of two members. In the aforementioned type A, if the amount of stemmed manuscripts increases, the detection plate 1 4 6 rotates along the track shown by the arrow 2 1 in FIG. 3 and the center of the arm shaft 1 4 8. With this, the detection plate 1 4 7 is rotated around the arm shaft 1 4 8 along the track ′ indicated by the arrow 202. In the case where the detection arm 1 4 7 follows this orbit, and the rotation angle of the detection arm 1 4 7 increases constant, the amount of movement of the bran sieve wire 1 4 2 and the door wire 1 4 3 changes when the amount of stem discharge is large. It is larger than when the amount of row is smaller. Type A exhibits this tendency more significantly than type B. As the amount of stemmed manuscripts increases, the range of the bran wire 1 2 2 increases non-linearly. Compared with the amount of stemmed manuscripts, the amount of stemmed manuscripts increases. The larger the change in the opening degree of the bran sieve 55, the greater the increase. In this way, the A type has a simple structure, and can be controlled well and reliably, which helps to improve the performance of selection. Since the structure of the B type can be replaced with the A type, only the detection arm 1 4 7 can be replaced, and the position of the wire rack 1 95 can be changed. Therefore, ′ can be changed to a structure that can obtain good selection performance at a lower cost. In addition, even in the above type A, if the bran screen wire 1 4 2 is connected to the door wire 1 4 3 of the detection arm 1 4 7, the movement of the door wire 1 4 3 also increases with the number of stems and increases non-linearly. Compared to when the amount of stemmed manuscripts is small, the larger the amount of stemmed manuscripts, the greater the change in the opening degree of the shutters 139, 140, and the more appropriate the air supply amount corresponding to the descaling treatment amount. In addition, the above structure is of course configured to connect Ying Bran sieve 1 4 2 to Ying Bran (please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 (210X297 mm) -42 -558415 Printed by A7 B7, Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (40) Sieve lever 1 3 8 The mechanical opening of the sieve 5 5 can be changed by linking the sieve motor 1 The switching lever of 5 7 1 5 5 is used to fine-tune the opening degree, but it can also be adjusted by the controller 1 9 4 which controls the movement of the rice bran sieve 1 4 2 1 5 7 The second embodiment. As shown in Figs. 3 5 and 36, a bran serving as an actuator is arranged near the steel wire rack 1 9 5 connected to the bran sieve wire 1 4 2 for detecting the amount of stalk discharge. The sieve opening motor 1 5 7 directly changes the opening angle of the sieve motor 1 5 7 by adjusting the opening angle of the sieve motor 1 5 7 to adjust the cylinder arm 1 5 8 a and the steel wire. Frame 1 9 5. And it is configured that the controller 1 9 calculates the appropriate opening degree of the rice bran sieve 5 5 according to the information from the aforementioned sensors such as the rice bran sieve sensor 1 1 1 and the selected flow sensor 1 7 2. The controller 1 94 is connected to the motor driving circuit 1 9 of the aforementioned bran sieve opening degree motor 15 7 to control the driving of the bran sieve opening degree motor 15 7 to extend and retract the opening adjustment cylinder 1 58. Therefore, by adjusting the position of the steel wire frame 1 5 5 of the cylinder barrel arm 1 5 8 a which is fixed to the opening adjustment cylinder tube 1 5 8, the strokes of the bran screen wire 1 4 2 and the door wire 1 4 3 are finely adjusted. . According to the above configuration, the opening degree of the rice bran sieve 5 5 is changed by the lever 1 3 8 of the bran sieve, and the operation of the lever 1 3 8 of the rice bran sieve is compared with the structure of finely adjusting the opening degree by switching the lever 1 5 5. The source is reduced from two places to one. Since the bran sieve lever 1 3 8 is pulled and the bran sieve 1 4 2 is controlled near the wire rack 195, the control accuracy can be expected to improve. And because there is no need to adjust the opening of the bran sieve 5 5 by the switching lever 1 5 5, there is no need to connect the switching valve 1 5 5 and the opening adjustment cylinder 1 15 8 of the cylinder arm 1 5 8 a.

Description of the invention (41) Change the wire 1 6 0 and its surrounding components, Therefore, the number of structural elements can be reduced, and it has advantages in simplification of the assembly process and cost reduction. (Please read the precautions on the back before filling this page.) According to the second embodiment described above, the controller can be set by 1 9 4. As shown in the first embodiment (FIG. 31, 198), the change of the stroke of the wire relative to the amount of stemmed paper is shown. The compound can be controlled as shown in Type C (2 1 0 a) of Figure 3 '. The predetermined singular or plural number of benchmark stem manuscripts (η 1 · η 2 .........) can be controlled until it reaches Before the reference amount of stemmed paper (η 1 · η 2 .........), the stroke of the wire relative to the amount of stemmed paper increased linearly, with the reference amount of stemmed paper (η 1 · η 2. ........) as the limit, increase the variation of the wire stroke. At this time, with respect to the opening degree of the rice bran sieve 5 5 (Figure 3 8 2 1 0), the reference stem discharge amount (η 1 · η 2 ...) is given as Limit, increase the amount of change in opening. In addition, the amount of change can not only increase the limit of the amount of manuscripts (η 1 · η 2 .........) as the limit, but also make the amount of change zero, and also set the bran sieve 5 5 A row with a constant opening. And, by increasing the number of reference stem-stripping manuscripts (η 1 · η 2 .........), more precise control can be expected. Moreover, it is preferable that the above-mentioned change form of the wire stroke is selected according to the ability and form of the combine.

Of course, the present embodiment is configured to detect the amount of stemmed manuscripts processed by the amount of stemmed manuscripts carried by the stemmed manuscript chain. It can also be configured to detect the dehydration treatment amount by knowing the amount of stalks conveyed by the feed chain 7 and shaking the processing amount on the selection mechanism 1 2 5. Secondly, with reference to FIGS. 22 to 24 and FIGS. 40 to 42, it is explained that the opening degree of the bran sieve is automatically adjusted according to the increase and decrease of the dehydration treatment amount.

As mentioned above, the structure shown in Figs. 2 2 to 24 is the electrical control, that is, the controller 1 9 4 (the bran sieve motor 1 5 7) corrects the bran sieve lever 1 5 5 only in the row. In the case where the amount of stem manuscript (the amount of decanting treatment) is larger than the predetermined amount, the degree of opening can be adjusted, and the predetermined amount can be changed. On the other hand, the structure shown in FIG. 40 or FIG. 41 is mechanically controlled. That is, by mechanically adjusting the distance between the aforementioned detection chain 1 4 5 and the detection plate 1 4 6, and by changing the detection chain 1 4 5 acting on the detection plate 1 4 6 required discharge amount, delaying the increase of the bran sieve 5 5 The structure of the opening period of the adjustment.

The bottom of the invention description (43) has the abutting end 7 7 and The contact distance of the detection board 1 4 6. The adjusted length 7 9 of this structure is increased, and the abutment distance 7 8 is increased. Conversely, the adjusted length 7 9 is decreased, and the abutment distance 7 8 is decreased. In addition, when the abutment distance 7 8 is increased, it is necessary for the abutment end 7 7 to act on the detection plate 1 4 6 before the amount of stem manuscripts (the amount of off-cut processing) needs to be greater than before the increase. That is, before the adjustment of the opening degree of the bran sieve 5 5 is required, the amount of stalk discharge (descaling treatment amount) must be large, in other words, a small amount of time before the stalk discharge (descaling treatment amount) reaches a predetermined amount. Next, the opening degree of the bran sieve 5 5 was not adjusted. In this way, in the case where the amount of stem-stripping manuscript (the amount of decanting treatment) is small, the opening degree of the bran sieve 5 5 is not enlarged, that is, by maintaining the minimum opening degree, it is possible to prevent the branched stalks, The stem manuscripts are leaked from the bran sieve 5 5 to improve the quality of the kernels recovered by the primary conveyor 2 2. These branched stems and stem manuscripts can be introduced into the secondary conveyor 2 3 to increase the secondary return flow. It is processed by the stem of the secondary processing mechanism 10. In addition, the direction and position of the stop bolt 242 and the detection arm 147 are considered as shown in FIG. 40 and also as shown in FIG. 41. The configuration (type A) of Fig. 40 has a parabolic increase characteristic as shown in the curve 3 0 1 in Fig. 4 2 after the opening change adjustment of the bran sieve 55 is started. The amount of manuscript increases, and the increase in the opening degree per unit of increase in the amount of manuscripts is increased. The configuration of Figure 41 is proportional, that is, as shown in Figure 4 2, the straight line 3 0 3 increases substantially linearly. Characteristics (regardless of the increase or decrease in the amount of stemmed manuscripts, the increase in the amount of openness per unit of the amount of stemmed manuscripts is constant).

This structure is selected by The wind effectively acts on the grains, stems, etc. before and after the leakage, and prevents the accumulation of kernels, stems, etc. on the grain sieve 4 9. The granules that were leaked to the secondary conveyor 2 2 were intended to be transported to the trough 12 and led to the secondary conveyor 2 3 to increase the secondary return flow, and the improvement of quality was used as its purpose. 0 ie, such as As shown in FIG. 43, it is provided with a primary recovery mechanism that transports a primary object to a chute via a primary conveyor and a poppet conveyor; and sends a secondary object to a secondary processing mechanism via a secondary conveyor and a secondary return conveyor. , By using this secondary processing mechanism to remove branches and stems, and then put into the secondary material return circulation mechanism of the selection department; wind selection mechanism composed of one or more fans; (Please read the precautions on the back before filling this page ) This paper size applies Chinese National Standard (CNS) A4 (210X297 mm) -47- 558415 A7 B7 V. Description of the invention (45) Shake the selection mechanism; and make the selection wind flowing above the primary conveyor flow from the front to Windy road behind. (Please Read the precautions on the back and fill in this page again.} The first flow plate that guides the pellets to the previous conveyor is configured to be low front and high back, forming a diagonally upward guide to the rear side to hit the first flow plate. The above-mentioned selection of the wind path. The structure is described in detail below, as well as its function and effect. As shown in Fig. 4 and 3, the primary recovery mechanism is composed of a primary conveyor 2 2, a lifting conveyor 13, and a trough 12 (Figure 1). The secondary return circulation mechanism is composed of a secondary conveyor 23, a secondary return conveyor 14, and a secondary processing mechanism 10. The wind selection mechanism is a dust-feeding fan 1 3 1 which is a front fan. It is composed of a wind separator 2 5 which is a main air supply device itself. In addition, the shaker selection mechanism horizontally arranges the forward feed plate 5 2 from above-> rear feed plate 5 3, bran sieve 5 5, fixed bran sieve portion 5 7-flow plate 5 8 and bran sieve 4 9 The layered division shakes the inside of the body 50 to form a plurality of wind paths for the wind selection mechanism 67 to generate the selection winds to pass through. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs as shown in Figure 4 3, this air path uses the space between the forward feed plate 5 2 and the rear feed plate 53 as the first air path 4 0 1 and the dust fan 1 3 1 The generated first selection wind 501 flows to the first wind path 401. Since this first air path 4 0 1 is formed by horizontally arranging the front feeding plate 5 2 and the rear feeding plate 5 3, the first selection wind 5 0 1 flows from the front to the rear and is attracted by the suction fan 30. The forces complement each other and work to guide the crusts, stems, etc. that have leaked from the aforementioned wave nets 3 1, 2 1 a to the rear. -48- This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) 558415 A7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs B7 V. Description of the invention (46) Feeding board 5 3 The space between the plates 58 is used as the second air path 402, so that the second selection wind 502 generated by the wind separator 25 is flowed to the second air path 402. Since the second air path 4 0 2 is formed by being horizontally arranged horizontally, the feeding plate 53 and the flow plate 58 are formed. Therefore, the second selection of the wind 5 0 2 flows from the front to the rear, and at the same time, 'the attraction of the suction fan 30 complements each other, and plays a role in directing the kernels, stems, etc. leaked from the aforementioned bran sieve 5 5 to Farther back. Since a part of the second selection wind 5 2 0 (5 0 2 a) escapes to the upper part of the bran sieve 5 5 and flows upward, it plays a role without hindering the small-stemmed stalk grains, Stem drafts etc. flowed in from the bran sieve 5 5. In addition, the space below the streamer plate 5 8 and the bran sieve 5 5 is used as the third wind path 4 0 3, so that the third selection wind 5 0 5 generated by the wind separator 2 5 flows to the third wind path. 4 0 3. Further, in the third wind path 403, behind the wind separator 25, at a position substantially the same height as the rotation center of the wind separator 25, a wind guide 5 2 5 having a triangular shape in a side view is disposed in the horizontal direction. This wind guide 5 2 5 plays the role of controlling the amount of wind and direction of the third selection wind 5 0 3. In this embodiment, the third selection wind 5 0 3 forms upward, downward two air flows 503b, 503c, and is configured to be upward, etc. The selection wind 5 0 3 b flows obliquely upward and backward, and the third selection wind 5 0 3 c flows obliquely downward and backward. In addition, the shape of the wind guide 5 2 5 is not limited to a triangular shape in cross section, and may be a circular arc shape or a plate shape. In addition, the side view of the wind guide member 5 2 5 can be arbitrarily adjusted, so that it can also be used to fine-tune the third selection wind 5 0 3.

Description of the invention (47) (Please read the attention on the back Please fill in this page again.) Moreover, the third selection of the above-mentioned winds 503b, 503c flow from the front to the rear, and they are also complemented by the attraction of the suction fan 30, which keeps no wind loss and hits the first streamer plate 4 1 0. The first flow head 4 1 10 is inclined obliquely rearward from the primary conveyor 22 and the upper end is arranged below the rear end of the grain sieve 4 9 to separate the third air path 403 and the space 405 provided with the secondary conveyor 23. Here, the inclination of the first ballast plate 4 1 0 becomes front low and then high (about 30 degrees in this embodiment). In addition, by this inclination of the first grate plate 410, the wind direction of the third selection winds 503b and 503c is changed obliquely upward. With this wind direction change, the air current 5 0 3 a generated from the primary conveyor 2 2 through the bran sieve 5 5 and flowing into the suction fan 3 0 is generated on the first flow plate 4 1 0, and the air current 5 0 3 a passes The sieve sieve 4 9 sucks and leaks the husks, stems, etc., which are placed on the primary conveyor 22, and functions without hindering the small specific gravity of branched stems, broken ears, stems, etc. from entering the primary conveyor. In addition, when the third third selection wind 5 0 3 c collides with the first flow plate 4 1 0, a part of the wind direction is downward, and the particles on the surface of the first flow plate 4 1 0 are effectively reduced. Lead to the primary conveyor 2 2. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the above three types of selection winds 501, 502, and 503, and borrowed each wind path 40 1, 40, 40 3 above the primary conveyor to arrange or level the wind direction on each wind path 401. In 402, 403, the wind speed is ensured in a wide range from the front part to the rear part of the optional device, and the selection ability of the kernels, stems, etc. leaked from the wave net 3 1, 2 1 a is improved. In addition, the first and second selection winds 501 and 502 arrange the wind direction horizontally above the primary conveyor.

Containing content, recovering good quality glutinous grains. In addition, the third selection wind 503 arranges the wind direction horizontally above the primary conveyor, and the stalk kernels, broken ears, stems, etc. with a small interference blocking ratio flow into the primary conveyor through the sieve 4 9 22. As a result, by increasing the amount of stalks with branched stalks and the like leading to the secondary conveyor 23, it is possible to easily increase the amount of stalks with stalks and branched stalks treated by the secondary reflux cycle. As described above, even when the amount of descaling treatment is increased, branched grains, broken ears, stems, etc. are prevented from flowing into the primary conveyor 22, and at the same time, the stems are removed by the second reflux cycle. By reselecting, it is possible to improve the quality of the grains finally recovered in the tank 12, and to prevent the reduction of the amount of grains to be recovered due to the loss of sorting. Secondly, the structure of the above-mentioned bran sieve adjustment is adjusted to appropriately improve the selection ability of "selection", and at the same time, the secondary return flow is increased to improve the quality. This structure has a large amount of stem rowing (amount of dewatering treatment), a large opening of the rice bran sieve 55, and an increase in the amount of the sieve leaked from the rice bran. By selecting different winds, it effectively acts on the sieve along the rice bran sieve. Pre- and post-leakage kernels, stems, etc. 'prevent kernels, stems, etc. from accumulating on the kernel sieve, and perform "selection" appropriately. At the same time, the leakage should be intentionally dropped on the primary conveyor 2 2. The granules transported to the tank 12 are guided to the secondary conveyor 23, and the secondary return flow is increased to improve the quality.

In this case, 'as mentioned above, by preventing the branches with stalks, broken The remaining kernels, stems, etc. flow into the primary conveyor 22, and at the same time, the stems are removed and reselected by the second reflux cycle. The quality of the final kernels recovered on the aforementioned trough 1 2 can be improved to prevent sorting. The loss results in a reduction in the amount of crumbs. On the other hand, when the amount of stalks is reduced and the amount of drenches is reduced, the opening of the sieve 5 5 is reduced by the rotation of the sieve lever 1 3 8. The opening degree of the rice bran sieve 5 5 in the case that the amount of stem manuscripts (the amount of dewatering treatment) is small is shown in Fig. 3 and Fig. 3 1 (the same as in the case of the second embodiment shown in FIG. 37 and FIG. 38, and the structure shown in FIG. 40 and FIG. 41 is the same) as shown, and closed arbitrarily , The increase in the amount of sieves sieve opening is small), in the case of a small amount of stem manuscripts (the amount of dehydration treatment), it will be difficult to leak from the sifting sieve 5 5 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and as the amount leaked from the sieve 5 5 and the sieve 4 9 decreases, it floats in the wind path 40 1, 402 or implants in Ying The bran sieve 5 5. The husks and stems of the sieve sieve 49 are borrowed from the wind 501 and 502 to the fixed bran sieve 57 and leaked to the secondary conveyor 23, thereby increasing the secondary return flow. It is moved to the back of the crusts, stems, etc. under the action of the selection wind, and the improvement of the opening characteristics of the above bran sieve 5 5 (Figure 3 1. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 Mm> _ _ 558 415 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (51) Figure 32, Figure 37, Figure 38, (Figure 42), even when the amount of stem-stripping manuscript (the amount of decanting treatment) is small, the secondary return flow can be surely increased.
