Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a combine threshing and draining processing apparatus for a combine that is provided with a draining fall path for dropping a threshing drain from a draining outlet of the threshing apparatus in a long straw state and falling on the ground in a sideways posture.
[0002]
[Prior art]
In the above combine, conventionally, as shown, for example, in Patent Document 1, even if the threshing waste straw is continuously discharged from the outlet of the threshing device, the waste straw is dropped intermittently on the field scene. There was one in which a drain wall dropper 7 was provided in the dropping path.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-266663 (paragraph number [0019], FIGS. 2 and 3)
[0004]
[Problems to be solved by the invention]
As shown in Patent Document 1, the above-described waste drainer dropper 7 swings between an upward collection posture for receiving and collecting a fallen waste straw and a downward discharge posture for dropping the collected waste straw. An exhaust brace support 9 that is supported so as to be movable and a pair of springs 11 and 12 that act on the exhaust brace receiver 9 are provided. The tool 9 is maintained in the rising collection posture by the urging force of the pair of springs 11 and 12, and the waste straw collection progresses, and the waste straw receiver 9 swings downward against the pair of springs 11 and 12 due to the weight of the waste wall. As it moves, one of the springs 11 switches from a state of upwardly biasing the exhaust brace support 9 to a state of downward biasing. Collecting drainer When falling from the waste straw receiver 9, the cracker load disappears, so that one spring 11 is biased upward from the state in which the waste spring receiver 9 is biased downward due to the biasing force of the other spring 12. It is configured so that the waste brace support 9 is returned to the rising collection posture by the lifting operation by the pair of springs 11 and 12.
[0005]
For this reason, when the draining dropper is employed, the cost is high particularly from the viewpoint of the structure that enables the operation of the draining brace receiving device by the spring.
[0006]
In addition, if the amount of harvested cereal straw that is driven at high speed and supplied to the threshing device per unit time increases, the threshing waste straw is discharged from the threshing device at a high speed and a large amount is discharged. If the threshing waste straw is supplied to the dropper as it is, the dropper that has been swung down so that the collection waste straw falls will not easily return to the collection position due to the load of the falling waste straw, It was easy for the situation to fall through the dropper and fall continuously on the field scene. If the biasing force of the spring that operates the dropper to the rising collection posture is set so that the dropper returns to the rising collection posture quickly and firmly against a slight draining load, it is collected by the dropper. If the waste straw does not become heavy, the dropper will not switch to the downward discharge posture against the spring, and the collection straw that has fallen in a bundle on the field scene will become too heavy, making it difficult to collect it there were.
[0007]
It is an object of the present invention to be able to advantageously perform waste straw processing, which drops intermittently on a field scene even if the threshing waste straw is continuously discharged from the threshing apparatus, and falls on the field scene. An object of the present invention is to provide a combine threshing / dispersing apparatus for easy harvesting.
[0008]
[Means for Solving the Problems]
The configuration, operation, and effect of the invention according to claim 1 are as follows.
[0009]
〔Constitution〕
In the threshing drainer processing apparatus for a combine, the threshing draining path of the combine is provided with a draining falling path for dropping the threshing drainer from the outlet of the threshing apparatus on the ground in a long straw state and in a sideways posture. A drop restricting rod that can be switched between a closed state that is closed across and an open state that opens the draining wall dropping path, and a drive mechanism that constantly switches and drives the drop restricting rod between the closed state and the opened state. A drop control shelf is fixed at a level lower than the drop control rod of the discharge wall dropping path, and the drop control shelf has a threshing discharge wall on a horizontal or almost horizontal discharge wall mounting surface. Once Put By receiving it and dropping it to the ground, It is configured to regulate the falling of the threshing waste straw on the ground.
[0010]
[Action]
Since the drop regulating rod is always driven by the drive mechanism and switches between the opened state and the closed state of the waste straw falling path, even if the threshing waste straw is continuously discharged from the outlet outlet, The straw does not fall at the pace as it is discharged from the outlet of the waste straw, but is received by the drop regulation rod, and then falls while being regulated to fall after being stopped.
[0011]
When the threshing drainer that has passed through the fall regulation casket falls on the field scene as it is, the threshing drainer that has passed through the fall regulation casket drops onto the field scene as it is when driven to the open state, Although the drop restriction by the drop restriction rod is performed, it is easy to occur in some places that the waste straw falls continuously and continuously on the field scene. On the other hand, the threshing waste straw that has passed through the fall regulation rod is placed on the waste straw mounting surface of the fall regulation shelf, and subsequently pushed out from the waste straw placing surface by the falling threshing waste straw and falls onto the field scene. Therefore, the threshing waste straw from the fall regulation bowl does not fall into the field scene, but is received by the fall regulation shelf and dropped on the field scene while being dropped and regulated so as to fall. Go. Thereby, even if a large amount of threshing waste straw is discharged from the threshing device at a high speed, the threshing and falling straw is intermittently dropped onto the field scene accurately by receiving the fall regulation by the fall regulation basket and the fall regulation by the fall regulation shelf.
[0012]
Since the drop-control rod is always switched and driven, it is possible to collect the amount of waste straw dropped intermittently on the field by collecting the appropriate amount for collection on the weight surface, etc. by setting the drive speed of the drop-control rod appropriately Can be adjusted to the amount.
[0013]
〔effect〕
Therefore, even if the threshing device discharges a large amount of threshing waste straw at high speed, the threshing waste straw is released in a scattered state in a bundled state even if the threshing device discharge pace becomes any state. This makes it easier to collect. It is possible to easily perform the collection operation from this surface by adjusting the waste straws that have fallen together in the farm scene so as to be in a bundle of weights that are easy to support. On the other hand, it is possible to obtain a low cost by providing a relatively simple structure in which a drop regulation rod is provided so as to be switchable by a drive mechanism and a drop regulation shelf is provided.
[0014]
The structure, operation, and effect of the invention according to claim 2 are as follows.
[0015]
〔Constitution〕
In the configuration of the invention according to claim 1, the fall regulation rod is made of a spring material so as to be elastically deformed to the side of opening the drainer dropping path by the pressure of the received threshing drainer.
[0016]
[Action]
Even when a large volume of threshing waste straw is discharged from the outlet of the waste straw, when the fall regulation jar is driven to close, depending on the pressure of the threshing waste straw applied to the fall regulation jar, the fall regulation heel opens the drain wall falling path. The drop regulating rod is received by the threshing drainer while making it easy to avoid the occurrence of deformation or breakage due to a strong reaction force applied to the falling regulating rod or the drive mechanism.
[0017]
〔effect〕
Therefore, even if a large volume of threshing waste straw is discharged from the threshing device, it becomes rich in durability so that deformation or breakage of the fall restriction rod or the drive mechanism is unlikely to occur.
[0018]
The structure, operation, and effect of the invention according to claim 3 are as follows.
[0019]
〔Constitution〕
In the threshing drainer processing apparatus for a combine, the threshing draining path of the combine is provided with a draining falling path for dropping the threshing drainer from the outlet of the threshing apparatus on the ground in a long straw state and in a sideways posture. In addition, there are provided a drop regulation cage urged in a closed state that crosses the waste wall dropping path, and a fall regulation shelf fixed at a lower arrangement level than the fall regulation cage, and the drop regulation cage Is configured to receive the threshing waste straw and open the waste straw falling path against the urging force by the weight of the waste straw more than the set weight to drop the threshing waste straw, and the fall regulation The shelves place the threshing waste straw on a horizontal or nearly horizontal waste straw mounting surface. Once Put By receiving it and dropping it to the ground, It is configured to regulate the falling of the threshing waste straw on the ground.
[0020]
[Action]
Even if the threshing waste straw is continuously discharged from the outlet of the waste straw, it is received and collected by the drop restriction rod, and if the weight of the waste straw exceeds the set weight for this collection, the fall restriction rod closes and resists urging. Then it becomes open and the waste straw falls. As a result, the threshing waste straw from the outlet outlet is not dropped at a pace that is discharged from the outlet outlet, but is received by the fall regulation rod and dropped while being dropped and regulated so as to fall. .
[0021]
When the threshing waste straw that has passed through the fall regulation casket falls on the field scene as it is, the threshing drainer that has fallen through the fall regulation casket when it falls into the open state falls onto the field scene as it is. Although the drop restriction is performed by the drop restriction rod, it is easy to occur in some places that the waste straw falls continuously and continuously on the field scene. On the other hand, the threshing waste straw that has passed through the fall regulation rod is placed on the waste straw mounting surface of the fall regulation shelf, and subsequently pushed out from the waste straw placing surface by the falling threshing waste straw and falls onto the field scene. Therefore, the threshing waste straw from the fall regulation bowl does not fall into the field scene, but is received by the fall regulation shelf and dropped on the field scene while being dropped and regulated so as to fall. Go. Thereby, even if a large amount of threshing waste straw is discharged from the threshing device at a high speed, the threshing and falling straw is intermittently dropped onto the field scene accurately by receiving the fall regulation by the fall regulation basket and the fall regulation by the fall regulation shelf.
[0022]
〔effect〕
Therefore, even if the threshing device discharges a large amount of threshing waste straw at high speed, the threshing waste straw is released in a scattered state in a bundled state even if the threshing device discharge pace becomes any state. This makes it easier to collect. On the other hand, it can be obtained at a low cost because it requires a relatively simple structure in which the drop restricting rod is provided in a closed and energized state and a drop restricting shelf is provided.
[0023]
The configuration, operation, and effect of the invention according to claim 4 are as follows.
[0024]
〔Constitution〕
In the configuration of the invention according to claim 3, the fall regulation rod is made of a spring material, and is configured to be elastically deformed from the closed state to the open state by the weight of the received threshing drainer.
[0025]
[Action]
If one end of the drop restricting rod is fixed to the support and supported, and the outlet wall pressure acts on the drop restricting rod, the drop restricting rod itself will be elastically deformed to open the drop path and pass the waste wall. This is to avoid applying an excessive load on the bag.
[0026]
〔effect〕
Therefore, a simple structure that simply employs a spring material that is fixedly supported as a drop restricting rod is sufficient, and it can be obtained at low cost.

That is, the catching action on the threshing drainer and the release of this catching action are repeatedly performed so that the threshing drainer that has fallen from the outlet outlet 6b is temporarily stopped by the fall regulation rod 33 and dropped on the fall regulation shelf 34.
[0035]
The operation panel 65 is provided with a speed change switch 67, and by operating the speed change switch 67, the drive speed of the electric motor 60 is changed between low speed and high speed so that the switching drive speed of the drop restriction rod 33 is switched between low speed and high speed. It can be switched to two stages.
[0036]
As shown in FIG. 7, the drop regulation shelf 34 is bent or molded so as to have a waste wall mounting surface 34a that is horizontal or substantially horizontal and has a longitudinal length L (depth) of about 140 mm. A part of the plate 30 is formed. The threshing waste straw that has fallen through the fall regulation rod 33 is placed on the waste straw mounting surface 34a, and the waste straw placed on the waste straw mounting surface 34a is pushed out by the threshing waste straw that has been dropped later and placed on the waste straw mounting. It slides on the surface 34a or rolls to fall from the waste straw mounting surface 34a. Thereby, the fall regulation shelf 34 regulates the fall of the threshing waste straw from the fall regulation basket 33. That is, the threshing waste straw that has fallen from the fall restriction rod 33 is temporarily stopped on the waste straw mounting surface 34a and then dropped on the ground so as not to fall on the ground. Moreover, by rolling the threshing waste straw on the waste straw mounting surface 34a, the threshing waste straw is brought into a state of being gathered so as to reduce looseness and dropped on the ground.
[0037]
That is, in this waste straw processing apparatus A, as shown in FIG. 5, the cutter case 11 of the waste straw shredding apparatus 10 is provided so as to be swingable so as to open and close the waste straw receiving port 12. 13 and a switching lever (not shown) provided in the operation unit in conjunction with the conveyance end side guide rod portion 22a of the waste straw conveying device 20 to operate the lid 13 in an open state and a closed state. By switching the conveyance guide rod 22 between the shortened state and the extended state, the waste straw processing for releasing the threshing waste straw in a shredded state or discharging in the long straw state is performed. ing.
[0038]
That is, when the lid 13 of the waste straw shredding device 10 is opened and the transport guide rod 22 of the waste straw transport device 20 is switched to the shortened state, the waste straw transport device 20 is removed from the threshing feed chain 6a. The threshing waste straw is transported to the rear side of the machine while moving to the tip side with respect to the threshing machine body in a sideways posture by the stock holding side holding and conveying apparatus 23 and the tip side locking and conveying apparatus 25, and When reaching the upper side, the holding by the endless rotating chain 21 and the conveying guide rod 22 of the stock holding side holding and conveying device 23 is released and dropped. Then, the threshing waste straw that has fallen from the waste straw conveying device 20 enters the cutter case 11 through the waste straw receiving port 12 of the waste straw shredding device 10 and is driven and rotated inside the cutter case 11. A disk cutting blade 16 that is driven to rotate by the cutter shaft 14 that is dropped onto the shaft 14 and the supply shaft 15 and is rotatably attached to a plurality of locations on the cutter shaft 14, and a plurality of locations on the supply shaft 15. A disk supply blade 17 that is rotatably attached and is driven to rotate by the supply shaft 15 is squeezed between them and cut into a chopped state having a length determined by the array pitch of the disk cutting blades 16 in the slimming direction. Is done. The shredder falls from between the cutter shaft 14 and the supply shaft 15 to the lower part in the cutter case, contacts the diffusion auger 18 that is driven and rotated, and receives a diffusion action, and is positioned below the diffusion auger 18.

On the other hand, when the lid 13 of the waste straw shredding device 10 is closed, and the transport guide rod 22 of the waste straw transport device 20 is switched to the extended state, the waste straw transport device 20 is moved to the threshing feed chain. The threshing waste straw from 6a is moved sideways by the stock-side holding and transporting device 23 and the tip-side locking and transporting device 25, and moved to the tip side with respect to the threshing body while the draining shredding device 10 is moved to the rear side of the body. It is transported to the vicinity of the rear part and discharged from the outlet outlet 6b to the rear side of the machine body in a state of a long sider and in a sideways posture. The threshing waste straw discharged from the waste straw outlet 6b falls to the ground through the waste straw falling path 32 in the sideways posture.
If the operation switch 66 is switched on when performing the long straw discharge process, the pair of left and right drop restriction rods 33 are always driven to be switched between the closed state and the open state by the electric motor 60. By repeatedly receiving and releasing the threshing drainer, the threshing drainer is controlled to drop so that it falls once after being stopped by the fall control bar 33 so as not to fall continuously as shown in FIG. While falling. Further, the threshing waste straw that has passed through the drop regulation basket 33 falls on the fall straw mounting surface 34a of the fall regulation shelf 34, temporarily stops and then drops while being regulated to fall to the ground. Thereby, even when a large amount of threshing waste straw is carried out at a high speed from the outlet outlet 6b, the threshing waste straw does not continuously fall on the field scene, but is collected and dropped intermittently. It falls to the field scene. Moreover, it rolls on the waste straw mounting surface of the fall control shelf 34, and it falls after gathering, it falls in the collection state with little dispersion | variation on a field scene.
[0040]
The lid 13 of the waste straw shredding device 10 is closed, the transport guide rod 22 of the waste straw transport device 20 is switched to the extended state, and the operation switch 66 is switched off so that the drop restriction rod 33 is When the waste straw falling path 32 is stopped in an open state, the threshing waste straw discharged from the waste straw outlet 6b by the waste straw conveying device 20 continuously falls on the waste straw falling path 32 and this waste straw. It continuously falls on the farm scene from the fall path 32. At this time, as shown in FIG. 10, the flexible synthetic resin sheet 70 suspended from the free end portion of the lid body 13 covers the fall regulation shelf 34, and the threshing drainer is placed on the fall regulation shelf 34. It guides so that it may fall, without mounting on the waste straw mounting surface 34a.
When discharging the waste straw while driving the drop restriction rod 33, as shown in FIG. 7, the synthetic resin sheet 70 is pressed against the cutter case portion 11a by the drop restriction rod 33 driven in the closed state, The threshing waste straw comes to be placed on the waste straw mounting surface 34 a of the drop regulation shelf 34.
[0041]
As shown in FIG. 6, an adjusting screw mechanism 56 is provided between the interlocking rod 51 and the joint 55 connecting the interlocking rod 51 to the output body 53 b of the crank device 53 and the operation member 37 b of the rotating support shaft 37. By operating the adjusting screw mechanism 56, the length between the joints 55 of the interlocking rod 51 changes, and the operating range of the drop restricting rod 33 approaches the cutter case part 11a or the cutter case part 11a. It can be adjusted away from.
[0042]
The pair of left and right drop restriction rods 33 are made of a strip-shaped spring material. That is, when the operating range of the drop restricting rod 33 is adjusted to approach the cutter case portion 11a and the drop restricting rod 33 is operated to the closed state, the free end 30a strongly contacts the cutter case portion 11a. Or when the volume of the threshing drainer discharged from the outlet outlet 6b is large, the drop regulating rod 33 is discharged by the contact reaction force from the cutter case portion 11a or the pressure of the threshing drainer. It is elastically deformed to the opening side of the dropping path 32 so that the damage of the drop regulating rod 33 can be avoided.
Moreover, when the operating range of the drop restricting rod 33 is adjusted toward the cutter case portion 11a, the portion of the operating range of the drop restricting rod 33 in which the free end 33a is in contact with the cutter case portion 11a. However, the free end portion 33a is allowed to remain in contact with the cutter case portion 11a due to the elastic deformation of the drop restricting rod 30, and the lower restricting rod 33 closes the discharge wall dropping path 32. The time during which the threshing drainer is temporarily stopped is lengthened.
[0043]
[Second Embodiment]
FIG. 11 shows the threshing waste straw processing apparatus A having the second embodiment. In this threshing waste straw processing apparatus A, the threshing waste having the first embodiment only in the point of the drop regulation rod 33. This is different from the straw treatment apparatus A, and only this point will be described.
[0044]
That is, the horizontal support rod 71 is fixed over the pair of left and right support arms 35, and the upper end portion of the drop regulating rod 33 is fixed and supported by a bracket 71 a fixed to the support rod 71. Each of the pair of left and right drop restricting rods 33 is made of a strip-shaped spring material, and the free end portion 33a is formed on the case portion 11a facing upward and downward of the machine body, which is located at a higher level than the drop restricting shelf 34 of the cutter case 11. In addition to being in contact, the support rod 71 is supported by the support rod 71 in a state of being slightly elastically deformed for this contact.
Thereby, each fall regulation rod 33 is urged | biased by the elastic restoring force which the fall regulation rod 33 has in the state which closed the waste straw fall path 32, and it receives and acts on the threshing waste straw discharged | emitted from the waste straw outlet 6b. As a result, when the weight of the temporarily stopped waste wall exceeds the set weight determined by the urging force of the drop restricting rod 33, as shown by the solid line in FIG. It is elastically deformed, and the waste straw falling path 32 is opened, and the threshing waste straw once stopped is dropped toward the fall regulation shelf 34.
[0045]
[Another embodiment]
As in the second embodiment, when adopting and implementing the drop restricting rod 33 that is biased to the state where the waste wall dropping path 32 is closed, the drop restricting rod 33 is made of a non-spring material such as a sheet metal, and the support rod 71 The threshing machine body is pivotally supported by the threshing machine body or the upper end side of the fall regulation bowl 33 is pivotally supported by the support bowl 71, so that the fall regulation bowl 33 swings back and forth with respect to the threshing machine body. In this way, the discharge wall dropping path 32 is switched between a closed state and an open state, and the supporting rod 71 is supported by various biasing means such as a supporting rod 71 or a coil spring or a leaf spring attached to the drop regulating rod 33.
