Behind the threshing device 16, there are provided a culm chain 18 that takes over and conveys the culm conveyed from the feed chain 15, and a cutter 19 for cutting the culm below the culm chain 18. Further, instead of the cutter 19 of this embodiment, for example, another working machine such as a knotter for binding the culm may be attached.

A vertical auger 4 and a horizontal auger 5 are provided to discharge the grains outside the machine when the grain volume in the Glen tank 3 becomes full. The vertical auger 4 is configured to be driven to rotate left and right by an electric motor 20. That is, the rotational force of the motor 20 is
a through the gear 21 on the vertical auger 4 side. Further, the horizontal auger 5 is lifted and lowered by the hydraulic cylinder 22. The cylinder side of the hydraulic cylinder 22 is loosely fitted to the vertical auger 4, and the piston rod 22 a side thereof is loosely connected to the base of the fixed cylinder 5 a of the horizontal auger 5.
The horizontal auger 5 rises when the hydraulic cylinder 22 is extended, and falls when the hydraulic cylinder 22 is contracted.

The horizontal auger 5 is composed of a fixed cylinder 5a and a movable cylinder 5b. The moving cylinder 5b is fitted to the fixed cylinder 5a, and is configured to expand and contract in the longitudinal direction which is the cylinder direction, that is, the upper side and the lower side in the conveying direction of the grain culm. The expansion and contraction configuration of the moving cylinder 5a will be described. An electric motor 23 is mounted behind the fixed cylinder 5a via a fixed cylinder flange 24. A screw shaft 25 is attached to an output shaft of the motor 23, and a metal 26 having a female screw to be fitted to the screw shaft 25 is fixed to the movable cylinder 5b.

The details of the horizontal auger 5 will be described with reference to FIGS. A spiral 27 is fixed to a shaft 28 inside the fixed cylinder 5a. A plurality of bosses 30 are provided inside the movable cylinder 5b so as to be fitted to the shaft 29, and a spiral 31 is fixedly provided on the boss 30. An extendable spring conveyor 32 is provided between the bosses 30.

When the harvesting operation is performed by advancing such a combine, the culm planted in the field scene is weeded by the weeding tool 9, raised, raised in the case 10, and cut by the cutting blade. Reaped at 11. Then, the stock transfer device 12
And transferred to the supply / conveyance device 8. The grain stalk taken over by the supply / conveyance device 8 is further conveyed backward. And the feed chain 1 of the threshing device 16
5 and the culm is threshed by the threshing device 16 while being conveyed rearward.

[0012] The kernels thus threshed and sorted are conveyed into the Glen tank 3 via the first deep-frying cylinder 33,
Stored temporarily. When the amount of grains stored in the Glen tank 3 becomes full, the operator is notified by the notification means of the operation unit 17. 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), the grain discharge port 6 is moved to a position such as the bed of the truck, and the grain discharge lever 34 of the operation unit 17 is set in the state, and the grain discharge port 6 is moved into the Glen tank 3. Discharges the kernels out of the machine.

In order to move the grain discharge port 6 to an arbitrary position, the horizontal auger 5 housed in the auger receiver 35 is raised by the hydraulic cylinder 22. Then, the motor 20 is driven to move the discharge port 6 of the horizontal auger 5 to an arbitrary position. To move the discharge port 6 to an arbitrary position, the moving cylinder 5b is also extended. Normally, the horizontal auger 5 receives the auger 35
5, the moving cylinder 5b is in its minimum size as shown in FIG. 5 (see FIG. 5), so that the moving cylinder 5b is also extended (see FIG. 6) when the grain is discharged. When the moving cylinder 5b is contracted, the bosses 30 are approaching each other and the spring conveyor 32 is contracted inside the moving cylinder 5b, as shown in FIG.

Next, when the motor 23 is driven with the extension switch 36 provided on the operation unit 17 being turned on, the screw shaft 25 rotates. Since the metal 26 fixed to the moving cylinder 5b is fitted on the screw shaft 25, the metal 26 moves toward the lower side in the grain discharging direction. Therefore, the moving cylinder 5b extends. At this time, the interval between the bosses 30 becomes longer inside the movable cylinder 5b, so that the spring conveyor 32 extends.

When the outlet 6 comes to a position desired by the operator,
The kernel in the Glen tank 3 is discharged with the kernel discharge lever 34 of the operation unit 17 turned on. Grain discharge lever 34
, The lower spiral (not shown) in the Glen tank 3, the spiral in the vertical auger 4 (not shown), the spiral 27 in the fixed cylinder 5a, the spiral 31 in the movable cylinder 5b,
The spring conveyor 32 rotates. Therefore, Glen tank 3
The grains inside are discharged from the discharge port 6 to the outside of the machine. When the discharge of the grains in the Glen tank 3 is completed, the reduction switch 37 is turned on to reduce the size of the movable cylinder 5b and store the horizontal auger 5 in the auger receiver 35.

The expansion switch 36 and the reduction switch 37 of the moving cylinder 5b are configured to operate even when the kernel is being discharged from the kernel outlet 6. However, if the moving cylinder 5b is extended or contracted at the time of discharging the grain, there is a high possibility that the grain will be scattered. Therefore, the speed at which the moving cylinder 5b expands and contracts at the time of discharging the grain does not discharge the grain. Try to be slower than sometimes. Thereby, scattering of grains can be prevented.

The positions of the extension switch 36 and the reduction switch 37 of the moving cylinder 5b are provided near the grain discharge port 6. Thus, when discharging the grains to the truck bed or the like, the operator can directly get on the cargo bed and change the position of the discharge port 6, so that the grains can be uniformly discharged to the truck bed. As described above, even when the expansion switch 36 and the reduction switch 37 provided near the discharge port 6 are operated, the grain is moved more slowly when the grain is discharged than when the grain is not discharged. Thereby, it is possible to prevent the grain and the dust from being scattered, particularly the worker who is getting on the loading platform.

As described above, the extension switch 36 and the reduction switch 37 of the moving cylinder 5b are connected to the operation unit 17 and the grain discharge port 6.
Although it is provided in the vicinity, it is slower to operate with the extension switch 36 and the reduction switch 37 provided in the vicinity of the grain discharge port 6 than the extension switch 36 and the reduction switch 37 provided on the operation unit 17 side. The configuration is as follows. Thereby, even if the extension switch 36 and the reduction switch 37 on the grain discharge port 6 side are carelessly operated, the movable cylinder 5b moves slowly, so that it is safe for a worker nearby. In addition, scattering of grains and dust at the time of discharge can be prevented.

Next, the configuration of the lever 38 for turning the grain discharge port 6 left and right, moving up and down, and extending and contracting will be described. The lever 38 is provided on the operation unit 17. The details will be described with reference to FIG. The lever 38 is configured to tilt in eight directions. Tilt in the A direction raises the horizontal auger 5, tilts in the E direction lowers the horizontal auger 5, tilts it in the G direction, turns the vertical auger 4 left, and tilts it in the C direction turns the vertical auger 4 right. , B, the horizontal auger 5 rises and the vertical auger 4 turns right,
When the horizontal auger 5 is tilted in the D direction, the vertical auger 4 is turned rightward while descending. When the horizontal auger 5 is tilted in the F direction, the vertical auger 4 is turned left while the horizontal auger 5 is lowered. When the left axle is tilted in the H direction, the vertical auger 4 is turned left while the horizontal auger 5 is raised.

On the head of the lever 38 having such a structure,
In this configuration, a switch 38a for extending the moving cylinder 5b and a switch 38b for reducing the size are provided. Therefore, during the operation of the state in which the lever 38 is tilted in any direction from A to H, the extension switch 38a and the reduction switch 38b are operated.
And the moving cylinder 5b can be extended and contracted simultaneously. Thereby, the position of the grain discharge port 6 can be promptly moved to a position desired by the operator.

The lever 38 may be provided near the grain discharge port 6. At this time, when the lever 38 on the grain discharge port 6 side is operated, the moving speed of the horizontal auger 5, the vertical auger 4, and the moving cylinder 5b is lower than when the lever 38 provided on the operation section 17 is operated. And delay it. Thus, even if the lever 38 is operated carelessly, it is safe.

However, when the lever 38 provided on the grain discharge port 6 side is operated, if the moving speed of the horizontal auger 5, the vertical auger 4, and the moving cylinder 5b is always slow, it may cause inconvenience. . Therefore, the operation unit 17
And the lever 38 on the grain discharge port 6 side.
Are provided with speed setting dials 39 in the vicinity of. The speed setting dial 39 has a knob shape, and has a configuration in which the speed is low when turned to the left and high when turned to the right. After the speed is set to an arbitrary speed with the speed setting dial 39, when the lever 38 is operated, the horizontal auger 5, the vertical auger 4, and the moving cylinder 5b move at the set speed. The speed setting dial 39 may be a stepless type or a stepped type.

[0023]

As described above, according to the present invention, the horizontal auger 5 is composed of the fixed cylinder 5a and the movable cylinder 5b which fits into the fixed cylinder 5a and moves in the longitudinal direction to extend and contract. The speed of expansion and contraction is such that when the grain is discharged from the grain discharge port 6 of the moving cylinder 5b, the moving cylinder 5b moves and expands slower than when the grain is not discharged.
Is safe because it travels slowly and can ensure the safety of workers nearby. In addition, scattering of grains and dust at the time of discharge can be prevented.
