As a result, the swinging phenomenon on the distal end side during the expansion and contraction operation is remarkably reduced as compared with the conventional drum-shaped roller.

Next, the operation will be described. First,
When the engine is started and the traveling body 8 is advanced while driving the rotating parts of the machine body, the culm in the field is cut by the cutting device 33 in FIG. 1, transported, and supplied to the threshing device. Then, after the culm is subjected to the threshing treatment action, the selected and carefully selected grains are fried by the first fryer,
It is sequentially supplied to the Glen tank 1 and stored.

As the harvesting and threshing work of the combine proceeds in this manner, the grain stored in the grain tank 1 in the grain tank 1 reaches a certain amount after the threshing work, and the Glen tank 1 is filled up with the full tank mounted inside the tank. An alarm is issued by the detection of the sensor, and the operation shifts to the work of carrying out the grain. First, the operator moves the traveling vehicle body 8 to the edge of the ridge, approaches the truck waiting on the farm road, and raises and lowers the swivel lever 3 of the grain discharge auger 14.
By operating the lifting hydraulic cylinder 23 and the revolving motor 24, the user moves to the target carry-out position by operating the lifting cylinder 4, and the grain discharge port 17 at the tip thereof faces the upper part of the tank of the truck.
Prepare for the grain discharge work.

At this time, the telescopic drive device 19 forcibly pushes the screwed moving device 22 while driving the telescopic control motor 20 by operating the telescopic switch from the cockpit to rotate the helical shaft 21 forward. Move forward (tip side). Then, the moving device 22 adjusts the grain discharge port 17 at the front end portion to the position above the tank of the truck while extending the integrally connected movable transfer tube 2 forward with respect to the fixed transfer tube 15. become. At this time, the telescopic control motor 20
The mobile device 22 is automatically stopped when pressing the limit switch S ₂ reaches a limit position of the extension side.

In this manner, the grain carrying auger 14 is
After the positioning of the grain discharge port 17 is completed, when the discharge clutch lever is operated to enter, the discharge spiral 9 at the bottom of the Glen tank 1 is moved from the discharge spiral 9 in the grain raising cylinder 12 to the grain feeding spiral 13 in the fixed conveying cylinder 15. The telescopic spiral 3 in the movable transport cylinder 2 is transmitted via the transport spiral 16 and the transmission shaft 4 and starts rotating.

Then, the grains in the Glen tank 1 are sent from the frying cylinder 12 to the fixed transport cylinder 15, further transferred to the movable transport cylinder 2, and discharged from the grain discharge port 17 to the outside of the machine.
They are sequentially carried out to truck tanks. When performing the above-described grain discharging operation, as shown in FIG. 1, the grain discharging auger 14 moves to the right of the combine, that is, to the left when looking back from the operation unit 30 and looking backward. Most of them are used. In this case, when looking back from the operation unit 30 and looking backward from the operation unit 30, the movable transport cylinder 2 has a leftward extending direction and a rightward downward contracting direction. Therefore, when the expansion switch 31 and the reduction switch 32 for reducing the size are provided behind the operation unit 30 and in front of the threshing device 35, the expansion switch 31 is provided on the left side, and the reduction switch 32 is provided on the right side. Get better. That is, when the extension switch 31 on the left side is pressed, the movable transfer tube 2 moves to the left, and when the reduction switch 32 on the right side is pressed, the transfer tube 2 moves to the right.
Since the positional relationship with the position 32 is matched, ergonomical use is facilitated and work efficiency is improved. The expansion switch 31 and the reduction switch 32 may be configured as an integrated seesaw switch.

Is provided with an emergency stop switch 37. Above the automatic extension / storage switch 36 and the emergency stop switch 37, a lifting / lowering turning lever 34 for the grain carrying auger 14 is provided. As a result, the switch group related to the grain discharge auger 14 is provided in a centralized location, so that this point is also easy to use.

Next, FIG. 7 will be described. A lamp 38 is provided on the upper surface of the movable transfer tube 2 so that the lamp 38 is turned on or blinks while the movable transfer tube 2 is moving. Thereby, the worker and the surrounding workers can easily grasp that the movable transfer tube 2 is moving and expanding and contracting.
Work can be performed safely. The position of the ramp 38 may be anywhere in the front-rear direction of the movable transfer tube 2;
Although it may be provided anywhere in the circumferential direction, the degree of appeal to the periphery is greater near the grain discharge port 17, that is, near the front end of the movable transfer cylinder 2 or at the front end. In the case of a large combine, the degree of recognition is higher on the lower surface side of the movable transport cylinder 2.

Next, FIG. 8 will be described. If the reduction switch 32 is kept depressed, the movable transport cylinder 2 comes into contact with the flange 39 fixing the fixed transport cylinder 15 and breaks, and the current continues to flow through the telescopic control motor 20. Then, there is a possibility that the expansion / contraction control motor 20 will be burned and damaged. Therefore, a limit switch 40 is provided on the flange 39, and the support roller 27 for supporting the moving and transporting cylinder 2 abuts on the limit switch 40, thereby cutting off the current to the telescopic control motor 20. It is configured to stop the movement and reduction of the movable transfer cylinder 2. As a result, it is possible to prevent the movable transport cylinder 2 and the expansion / contraction control motor 20 from being damaged.

Next, FIG. 9 will be described. Work light 41
Is provided, a cover 42 covering the spiral shaft 21 is provided.
Is provided. Conventionally, the wiring to the work lamp 41 was difficult because it was provided on the movable transfer tube 2. That is, since the movable transfer tube 2 expands and contracts, it is troublesome to process the wiring corresponding thereto, and a problem such as sometimes being caught and cut has occurred, as described above.
Since the cover is provided on the fixed cover 42, the wiring can be easily performed.

Next, FIGS. 10 and 11 will be described.
The support rollers 27 are provided only at the upper and lower positions of the movable transfer cylinder 2, but may be further provided in the left and right directions. Any position may be used as long as it is in the left-right direction. This allows
The moving transfer cylinder 2 can be more firmly supported, and the concentricity is improved, so that the moving expansion and contraction can be smoothly performed.

Next, FIGS. 12 and 13 will be described.
When the lifting cylinder 12 is turned to an arbitrary position, a problem occurs in that the grain discharge auger 14 turns by its own weight on an inclined ground. Therefore, a plate 43 is provided in the middle of the fryer cylinder 12, and a spring plate 44 is provided on the plate 43. Also, a frame 45 erected on the chassis 2
, A plate 46 having a plurality of holes 46a is fixedly provided.

When the fryer cylinder 12 turns, the spring plate 44 also turns and moves through the plurality of holes 46a on the fixed side. When the frying cylinder 12 stops, the spring plate 44 also stops at an arbitrary hole 46a. Thus, the spring plate 44 is
By being within a, the turning movement of the fryer cylinder 12 can be restricted. Therefore, even when the combine is stopped on the slope, the turning of the fryer cylinder 12 by its own weight can be prevented, and safety can be ensured.
