I have. In the present embodiment, the second processing cylinder 22 is provided on one side of the handling cylinder 15 and in front of the dust processing cylinder 19, and basically processes a second product. Further, since the processing object leaked from the handling net 14 is configured to be taken into the second processing chamber 224, the second processing cylinder 22 includes the processing object entering from the handling chamber 17 in addition to the second processing cylinder 22. Are also processed together. The handling net 14 and the second processing drum gutter 23
(It may be a net or a grid.) And the dust treatment net 18 are provided below the handling cylinder 15, the second treatment cylinder 22, and the dust treatment cylinder 19, respectively.

Below the handling chamber 17, the second processing chamber 24, and the dust processing chamber 20, a swing sorting shelf 21 for receiving and sorting falling objects to be sorted is installed. Sorting shelf 2
1, a Karin 25 is provided on the starting end side of the sorting wind feeding direction, and the first spiral 26 is provided on the lower side in the sending direction of the sorting wind blown from the Karumi 25, and the sorting wind feeding of the first spiral 26 is performed. A second spiral 27 is provided on the lower side in the direction.

The structure of the swing sorting shelf 21 will be described.
The swing sorting shelf 21 is arranged in order from the starting end in the sorting feeding direction.
It is composed of a transfer shelf 21a for transferring the fallen threshing material backward, a grain sheave 21b for selecting threshing material, a chaff sheave 21c for selecting the second threshing material, and a straw rack 21d for transferring and discharging dust to the outside of the machine. . The lower part of the straw rack 21d is constituted by a second shelf 27a for guiding a second object into the second spiral 27.
The configuration is such that the dust processing cylinder 19 extends to the vicinity of the terminal end of FIG. The cross flow fan 28 is for discharging the light dust in the sorting chamber 29 to the outside of the machine.
It is provided above 1d.

In the combine equipped with the threshing device 4 configured as described above, power from an engine (not shown) is input to the traveling transmission device 30 to drive the traveling device 1 by shifting the speed to an arbitrary speed. . The combine then starts moving forward. In order to perform the harvesting and threshing work, the power is further transmitted from the engine to the mowing device 3, the supply and transport device 3a, and the threshing device 4, and the work is performed. When the combine moves forward in such a state, the planted grain culm is weeded by the weeding tool 31 and is caused by the raising lugs 33 of the raising case 32. After that, it is cut by the cutting blade 34,
The harvested grain culm is conveyed by the stock transfer device 35 toward the start end of the rear supply conveyance device 3a.

Then, the cereal culm conveyed to the terminal end of the stock transfer device 35 is taken over by the start end of the rear supply / conveyance device 3a. Thereafter, the grain stalks that have been transported to the end of the supply and transport device 3a are carried over to the start end of the feed chain 11 of the threshing device 4, and the grain stalks that have been carried over to the feed chain 11 are transported rearward, Threshing is performed by the handling cylinder 15 and the handling net 14. A part of the threshed after threshing falls on the swing sorting shelf 21, is sorted by the swinging operation of the swing sorting shelf 21 and the wind sorting action from the Karamin 25, and is taken into the first spiral 26. I will go. The grains taken into the first spiral 26 are temporarily stored in the Glen tank 5, and the culms after threshing are removed from the terminal end of the feed chain 11.
It is taken over by the starting end of the culm chain 36 and transported. Then, it is sent to the cutter 37, cut, and discharged to the lower field.

The remaining thresh in the handling room 17 is transported rearward, and some of the thresh is taken into the second processing chamber 24 on the way. The thresh taken in the second processing chamber 24 is threshed by interaction between the second processing cylinder 22 and the second processing cylinder receiving gutter 23 while being conveyed to the upper side in the sorting wind feed direction (particularly, branch spikes). The grains are processed)
It falls on the swinging sorting shelf 21 below. In a situation where the handling cylinder 15, the second processing cylinder 22, and the dust processing cylinder 19 are both viewed from the sorting windward side to the downstream side (the front view of the threshing apparatus 4),
Since it is configured to rotate clockwise, therefore, the direction of the processing teeth 22a of the second processing cylinder 22 needs to be fixed in such a direction as to feed threshing material in the upstream direction in the sorting wind feeding direction.

That is, the processing teeth 22a have a function of transporting the processing object to the upstream side in the sorting air feeding direction, and also have a function of processing the processing object. That is, processed tooth 2
Numeral 2a is a part of the spiral, and is configured to process an object to be processed by an interaction between the tip end in the circumferential direction and the second processing cylinder receiving gutter 23. A blade 22b provided at the transport end of the second processing cylinder 22 forcibly sends out the object to be processed onto the swing sorting shelf 21.

The dust processing teeth 19b of the dust processing cylinder 19
Must be fixed in such a direction as to feed thresh to the lower side in the sorting wind direction. In the present embodiment, the dust processing teeth 19b have a spiral shape wound around the outer peripheral surface of the dust processing cylinder 19.

However, in the present embodiment, since the mesh of the dust treatment net 18 is rough (lattice-like), some of the short straw chips fall on the swing sorting shelf 21 and the long straw which has not fallen is dropped. The debris is conveyed to the end of the dust processing chamber 20, and is forcibly discharged onto the straw rack 21d by the blade 38 at the end of the dust processing cylinder 19. Then, while the object to be processed is conveyed in the dust processing chamber 20, the threshing is further performed by the interaction between the dust processing cylinder 19 and the dust processing net 18, and
The thresh is loosened to take out the grains (so-called sari grains) mixed therein, fall to the lower swing sorting shelf 21, and further collect into the second spiral 27.

As described above, the thresh in the handling room 17 does not fall on the swing sorting shelf 21 and remains in the second processing room 24. It is transported to the end. The thresh conveyed to the end of the handling room 17 is taken into the dust treatment chamber 20, and the thresh taken in is conveyed to the lower side in the sorting air feeding direction.

When the thresh is sent from the terminal end of the handling chamber 17 into the dust treatment chamber 20, the transfer of the thresh from the handling chamber 17 to the dust treatment chamber 20 is also performed so as to prevent the thresh from being clogged. A helical dust processing tooth 19b is provided on the outer periphery of the dust processing cylinder 19, and the feed-through action of the dust processing tooth 19b prevents the transfer portion from being clogged with threshing material.

In spite of the above-mentioned swinging action of the swinging sorting shelf 21 and the action of the sorting wind from the Karamin 25, the remaining kernels that are not taken into the spiral 26 most are other dusts. Is sent further rearward, and is taken into the second spiral 27. The second product taken into the second spiral 27 is returned to the lower side in the sorting air feeding direction of the second processing chamber 24 by the second fryer cylinder 39 and merges with the thresh from the handling chamber 17. Then, while being conveyed to the upstream side in the sorting wind direction, while being threshed by the interaction with the second processing cylinder receiving gutter 23, it is conveyed while being threshed. It is forced to fall.

The grains taken into the first spiral 26 are temporarily stored in the Glen tank 5. Then, when the grains in the Glen tank 5 are full, through the lower spiral 8, the vertical auger 12, and the horizontal auger 13, a discharge port 13a provided at the tip of the horizontal auger 13 and a machine such as a truck bed. It is discharged outside.

Next, the configuration of the Glen tank 5 will be described with reference to FIGS. Glen tank 5
It is divided into an upper Glen tank 5a and a lower Glen tank 5b. The lower spiral tank 8 is provided in the lower Glen tank 5b. And the lower Glen tank 5
“b” is a configuration fixed to the chassis 2 with bolts 40.

The upper Glen tank 5a is configured to be openable and closable laterally with a vertical axis 42 provided on a takeover metal 41 between the lower spiral 8 and the vertical auger 13 provided in the lower Glen tank 5b as an axis. The fixing at the time of storage of the upper Glen tank 5a is such that a pin 44 is provided on the front and rear frames 43 provided on the side of the threshing device 4, and a hook arm 45 provided on the upper Glen tank 5a side is engaged with the pin 44. The hook arm 45 is configured to rotate around a fulcrum 46 as an axis.
One end of 7 is loosely fitted. An arm 49 integrated with an opening / closing lever 48 is loosely fitted to the other end of the link arm 47, and the opening / closing lever 48 is configured to rotate around a fulcrum 50 as an axis. The fulcrum 50 has a torque spring 51.
And the torque spring 51 is connected to the hook arm 45 via the arm 49 and the link arm 47.
Is pressed downward, and the hook portion is engaged with the pin 44.

The upper Glen tank 5a is fixed at the time of storage, in addition to the above, and is further fixed with a lever pin 52. The lever pin 52 includes a compression spring 53
The lower end of the lever pin 52 is fixed by being inserted into a hole 54 formed in the lower Glen tank 5b. Of course, there is no problem because the lower Glen tank 5b is fixed to the chassis 2. As described above, since the upper grain tank 5a is fixed at two places, even when a large vibration or the like is generated during traveling of the combine, it is securely locked and safe. Further, since the hole 54 into which the lower end of the lever pin 52 enters is provided on the mating surface 7 of the lower grease tank 5b, when the lever pin 52 is inserted into the hole 54, the left and right directions of the upper and lower Glen tanks 5a and 5b are shifted. Is reduced as much as possible, so that the fixation of the upper Glen tank 5a during storage is further stabilized.

In order to rotate the upper Glen tank 5a to the side, the lever pin 52 is pulled up and released from the hole 54. Then, the hook arm 45 is released from the pin 44 by pulling the opening / closing lever 48 to the side. Then, the handle 55 fixed to the side of the upper Glen tank 5a is pulled to the side to open the upper Glen tank 5a to the side.

In the upper and lower Glen tanks 5a and 5b configured as described above, the mating surface 7 between the upper and lower Glen tanks 5a and 5b is substantially horizontal as shown in FIG. To be configured. Thereby, since the load of the upper Glen tank 5a acts evenly on the mating surface 7, the adhesion of the mating surface 7 is improved, and especially when the kernels are stored inside, the kernels spill out. Can be prevented.

An upper guide 56 is provided at the storage-side end of the mating surface 7 on the upper Glen tank 5a side.
A guide 57 facing downward is provided at the outer end of the mating surface 7 on the lower Glen tank 5b side. Thereby, when the upper Glen tank 5a is stored, the guide 56 and the guide 57 come into contact with each other and the upper Glen tank 5a
Can be smoothly placed on the lower Glen tank 5b, so that the resistance can be reduced and it can be easily stored.

Next, FIG. 6 will be described. In the communication hole 9 provided in the lower part of the upper Glen tank 5a and the communication hole 10 provided in the upper part of the lower Glen tank 5b, the communication hole 9 provided in the lower part of the upper Glen tank 5a is provided in the upper part of the lower Glen tank 5b. It is configured to be wider than the hole 10. Thereby, the lower Glen tank 5
Since the mating surface 7 on the b side is hidden below the upper grain tank 5a, it is possible to prevent the kernel from remaining on the mating surface 7 on the lower grain tank 5b side when the grain is discharged, and to reduce the discharge efficiency. improves.

Next, FIG. 7 will be described. FIG. 7 shows a transmission configuration of the lower spiral 8 provided in the lower Glen tank 5b. On the grain conveying side of the lower spiral 8,
A gear case 63 is provided between the lower Glen tank 5b and the engine 58. Inside the gear case 63, a bevel gear 63a fixed to an end of the lower spiral 8 and the bevel gear 6
A bevel gear 63b meshing with 3a and disposed on the outer side is provided. This bevel gear 63b
A pulley 61 is fixed to an end portion of a shaft 64 to which is fixed, and a belt 62 is wound around a pulley 60 provided on a radiator fan 59 side of the engine 58. The operation unit 6 is attached to the belt 62.
Is provided with a belt tension clutch 65 that stretches or loosens the belt 62 by an on / off operation of a grain discharge lever (not shown) provided in the apparatus.

When a grain discharging lever (not shown) provided on the operating portion 6 is turned on, the belt tension clutch 65 is turned on, and the power of the engine 58 is transmitted to the lower spiral 8 via the bevel gears 63a and 63b. Is communicated. As a result, the grains in the Glen tank 5 are transferred from the lower spiral 8 to the vertical auger 12 and the horizontal auger 13, and are discharged from the discharge port 13a to the outside of the machine.

Since the transmission of the lower spiral 8 is configured as described above, it is not necessary to touch the aforementioned transmission system (belt 62, etc.) when rotating the upper Glen tank 5a to the side. The Glen tank 5a can be easily turned to the side. Next, FIGS. 8 and 9 will be described.

Even if the upper Glen tank 5a is mounted on the lower Glen tank 5b and fixed by the lever pin 52, the upper Glen tank 5a is vibrated by the vertical vibration of the combine.
Vibrates up and down. Of course, as described with reference to FIG. 3, even if the hook arm 45 is engaged with the pin 44, basically the vibration in the vertical direction does not decrease. Therefore, a lifting prevention stay 66 is fixed on the mating surface 7 of the lower Glen tank 5b with a bolt 67, and a part of the mating surface 7 of the upper Glen tank 5a is projected as a projection 68. When the upper Glen tank 5a is stored, the protrusion 68 on the upper Glen tank 5a side is provided.
Is configured to enter between the floating prevention stay 66 and the mating surface 7 of the lower Glen tank 5b. Of course, when the lifting prevention stay 66 is provided on the mating surface 7 of the lower Glen tank 5b, the gap between the lifting prevention stay 66 and the mating surface 7 of the lower Glen tank 5b is slightly smaller than the protrusion 68 enters. It is necessary to keep a gap.

Thus, when the upper Glen tank 5a is stored on the lower Glen tank 5b, it is possible to prevent the upper Glen tank 5a from vibrating in the vertical direction. Next, FIG. 10 will be described.

A lower spiral roof 69 is provided on the lower spiral 8, and the role of the lower spiral roof 69 is to prevent the whole weight of the grain from acting on the lower spiral 8 and to activate the lower spiral 8. This is to make the grain smooth and prevent the grain from falling off. When the lower spiral 8 rotates, the grains acting on the lower spiral 8 are reduced by allowing the grains to flow into the lower spiral 8 from both sides of the lower spiral roof 69.

In providing the lower spiral 8, the lower spiral 8 is fixedly provided on the lower Glen tank 5b side. Thus, when the upper Glen tank 5a is rotated to the side, the gap 7 on both sides of the lower spiral roof 69 is formed.
Adjustment of 0,71 can be easily performed.

Further, as shown in FIG. 11, the lower spiral roof 69 may be fixedly provided on the upper Glen tank 5a side. The effect in this case is that the height 72 of the lower Glen tank 5b can be reduced, that is, the lower Glen tank 5b can be made compact, so that when the upper Glen tank 5a is turned to the side, the lower Glen tank 5b Maintenance can be easily executed.

[0038]

Since the present invention is constructed as described above, according to the first aspect of the present invention, since the load of the upper Glen tank 5a acts uniformly on the mating surface 7, the adhesion of the mating surface 7 is improved. It is possible to prevent the spilling of the grain, particularly when the grain is stored inside.

According to the second aspect of the present invention, the mating surface on the lower Glen tank 5b side is hidden below the upper Glen tank 5a. Can be prevented from remaining.
