The reaper 9 is supported by a reaper supporting frame 16 which moves up and down about a fulcrum above the traveling transmission device 15 at a substantially middle portion between the left and right sides. It is configured to move up and down together with the support frame 16. Above the undercarriage 2, the supply and transport device 10
A threshing device 18 having a feed chain 17 for taking over and transporting grain culms conveyed from the plant; a Glen tank 3 for temporarily storing the grains selected by threshing by the threshing device 18;
An operation unit 2a for performing various operations of the combine is mounted. Behind the threshing device 18, the feed chain 17
A culm chain 19 that takes over and conveys the culm conveyed from the culm and a cutter 20 that cuts the culm below the culm chain 19 are provided. Further, instead of the cutter of this embodiment, another working machine such as a knotter for binding the culm may be attached.

When the amount of grains in the Glen tank 3 becomes full, the grains are discharged from the grain discharging device 6 to the outside of the machine. The grain discharging device 6 includes a vertical auger 4 and a horizontal auger 5, and the horizontal auger 5 further includes a base auger 5a at a starting end side of the grain transport direction and a tip auger 5b at a terminal end side of the grain transport direction.
It is composed of Grain outlet 8 of tip auger 5b
Is movable from the start end side to the end side in the grain transport direction. In the present embodiment, the configuration is such that the motor 22 can turn around the rotation fulcrum 21. However, the configuration may be such that the base auger 5a can expand and contract in the longitudinal direction. Further, the base auger 5 a is configured to be received and stored in an auger receiver 7 installed above the Glen tank 3.

When the harvesting operation is performed by advancing such a combine, the culm planted in the field scene is weeded by the weeding implement 11, raised, raised by the case 12, and cut by the cutting blade. It is reaped at 13. Then, the stock transfer device 1
The sheet is transported at 4 and is taken over by the supply and transport device 10. The cereal stem that has been taken over by the supply and transport device 10 is further transported backward. Then, the culm is transferred to the feed chain 17 of the threshing device 18 and conveyed rearward, and the culm is threshed and sorted by the threshing device 18.

[0010] The grains thus threshed and sorted out are conveyed into the Glen tank 3 via the first deep-frying cylinder 23,
Stored temporarily. When the grain amount stored in the Glen tank 3 becomes full, the operator of the operation unit 2a is notified. Then, the operator interrupts the harvesting operation and starts the operation of discharging the grains in the Glen tank 3 to the outside of the machine. The grain combiner is moved to an arbitrary position (position near the truck) to move the grain discharge port 8 to a position such as the bed of the truck, and the grain discharge lever 24 of the operation unit 2a is set to the on state, and the grain tank 3 is moved into the Glen tank 3. Discharges the kernels out of the machine. To move the discharge port 8 to an arbitrary position, the hydraulic cylinder 30
Is operated, the base auger 5a is raised from the auger receiver 7, and the horizontal auger 5 is rotated together with the vertical auger 4 by driving the motor 31. Then, the motor 22 is driven to rotate the tip auger 5b to move the outlet 8 to the outlet. This series of movements of the grain discharging device 6 may be manual or automatic. In the case of automatic, the grain discharging device 6
A position sensor (not shown) is installed at each joint, and a desired discharge position is stored. When the automatic discharge switch is pressed, the discharge port 8 is automatically moved. I just need.

When the grain discharge lever 24 is in the on state,
The transport lower spiral 25 in the lower part of the Glen tank 3, the spiral 26 in the vertical auger 4, the spiral 27 in the base auger 5a, the take-up spiral 28, and the spiral 29 in the tip auger 5b are rotationally driven. Thereby, the grains in the Glen tank 3 are conveyed from the lower spiral 25 to the spiral 29 and discharged from the outlet 8.

When the grain discharge is completed, the grain discharge lever 2
4 is turned off, and rotation from the lower spiral 25 to the spiral 29 is stopped. Thereafter, the motor 22 is driven to rotate the tip auger 5b so that its longitudinal direction coincides with the base auger 5a in plan view. Then, the horizontal auger 5 is rotated by driving the motor 31 together with the vertical auger 4,
With the base auger 5a positioned above the auger receiver 7, the hydraulic cylinder 30 is operated to move the lateral auger 5 to the auger receiver 7.
To be stored inside. This series of movements may be manual or automatic. In the case of automatic operation, a position sensor (not shown) is installed at each joint of the grain discharging device 6, and the position of the auger receiver 7 is stored. The grain discharging device 6 may be stored in the auger receiver 7.

As described above, when moving the grain discharge port 8 of the grain discharge device 6 to an arbitrary discharge port, the motor 22
Is driven to rotate the tip auger 5b, and when the base auger 5a of the grain discharging device 6 is stored in the auger receiver 7, the motor 22 is first driven to rotate the tip auger 5b, In the plan view, the base auger 5a and its longitudinal direction are made to coincide with each other.

As another embodiment for moving the grain outlet 8 to an arbitrary outlet, the base auger 5a may be moving. Further, as another embodiment when the base auger 5a of the grain discharging device 6 is stored in the auger receiver 7, the motor 22 is driven to rotate the tip auger 5b, and the base auger 5a is also rotated to rotate the base auger 5a. The front auger 5b may be configured such that the longitudinal direction thereof coincides with the base auger 5a in a plan view while the 5a is turning.

Thus, when the tip auger 5b turns, it is safe when the base auger 5a is raised, that is, when the tip auger 5b is separated from the operator or the combine. In the above-described configuration, when the base auger 5a of the grain discharging device 6 is stored in the auger receiver 7, the tip auger 5b is first turned. However, first, the motor 31 is driven so that the base auger 5a is auged. After being positioned above the receiver 7, the tip auger 5 b may then be turned so that it matches the base auger 5 a in plan view.

When the grain discharge port 8 of the tip auger 5b of the grain discharge device 6 is moved to an arbitrary desired position, the motor 22 is finally driven to rotate the tip auger 5b. However, the base auger 5a is lifted and separated from the auger receiver 7, and then the motor 22 is driven to rotate the tip auger 5b. Then, the motor 31 is driven to drive the vertical auger 26 and the grain discharge port 8 of the tip auger 5b. May be turned.

Next, FIG. 3 will be described. When turning the tip auger 5b, the turning direction is turned in the direction opposite to the operation unit 2a in a plan view, that is, in the direction of the threshing device 18. As a result, it is possible to avoid the danger of contacting the operator existing in the operation unit 2a. Also,
Some combiners have a configuration in which a cabin is set in the operation unit 2a, but it is safe because contact with the cabin can be prevented.

Next, FIGS. 4, 5, and 6 will be described. Behind the combine, a cutter 20 for cutting the waste culm after threshing and a knotter device 3 for binding without cutting the waste culm
2 are provided. The operator selects which of the cutter 20 and the knotting device 32 to use with the cutter knotter switching lever 33 of the operation unit 2a. Cutter 2
When using 0, the cutter notter switching lever 33
Is moved upward. Then, the cable 34 is pulled, and rotates the L-shaped plate 35 counterclockwise around the fulcrum 35a against the tensile force of the tension spring 40. As a result, the pin 36 integral with the notch holding rod 37 is lowered, so that the notch holding rod 37 is also lowered.

When using the notter device 32, the cutter notter switching lever 33 is moved downward. Then, the cable 34 is pushed to rotate the L-shaped plate 35 clockwise about the fulcrum 35a. At this time, L
The tension force of the tension spring 40 is further applied to the mold plate 35, and the mold plate 35 is urged to rotate clockwise. As a result, the pin 36 integral with the notch holding rod 37 moves upward, and accordingly the notch holding rod 37 also moves upward.

As described above, since the culm holding rod 19a needs to hold the culm, it is constantly pushed upward by the front compression spring 38 and the rear compression spring 39. Since the notch holding rod 37 needs to hold the culm, the notch holding rod 37 is always pushed upward by the tension spring 40. With such a configuration, the culm after threshing and sorting by the threshing device 18 while being conveyed by the feed chain 17 is carried over from the end of the feed chain 17 to the beginning of the culm chain 19. The discharged culm carried over to the starting end by the discharged culm chain 19 is pinched by a discharged culm holding rod 19a and further conveyed rearward. As described above, when the notch holding rod 37 is lowered, the holding of the discharge culm is released, and the discharge culm is in a free state, and the lower cutter 20 is turned off.
Fall in the direction. Then, it is cut by the cutter 20 and falls onto the field.

When the notch holding rod 37 is raised, the culm conveyed to the end of the culm chain 19 is caught by the notch holding rod 37 and further conveyed rearward. . The excreted culm that has been conveyed to the end of the knotter holding rod 37 is sent to the knotter device 32 to be bound and discharged onto the field behind. As a conventional defect, at the transfer portion 41 between the end portion of the culm holding rod 19a and the knotter holding rod 37, there occurs a problem that the culm is clogged. This is because of the movement stroke A of the culm clamping rod 19a and the movement stroke B of the notter clamping rod 37.
Was the same. Therefore, the culm clamping rod
In the relationship between the movement stroke A of 9a and the movement stroke B of the notch holding lever 37, A <B. Suppose A>
In the relationship of B, the starting end of the notter sandwiching rod 37 becomes a resistance, and the grain culm is not smoothly taken over and becomes clogged in the worst case. It is smoothly carried over without receiving the resistance of the holding rod 37.

[0022]

As described above, according to the present invention, when the grain discharge port 8 is moved to the discharge position, the tip auger 5b is moved last, and when the grain discharge port 8 is stored in the auger receiver 7, the tip auger 5b is first moved. When the tip auger 5b turns, it is safe when the base auger 5a is raised, that is, when the tip auger 5b is separated from the operator or the combine.
