It is set as the structure which operates to the position of (open) and starts grain carrying-out work. When the work is completed, the discharge clutch lever 39 is operated to the position of the discharge clutch (disengaged) through the positions of the discharge clutch (on) and the shutter (closed) and is completed. According to this configuration, the discharge spiral 37 can be stopped with a predetermined time delay after the shutter 38 is closed.
[0019]
Next, the operation will be described.
First, the engine is started to drive the rotating parts of the airframe, while the crawler 10 is transmitted to advance the traveling vehicle body 6. Then, the grain culm in the field is weeded by the weed culm 14, and then the culm pulling device 15 is caused to stand upright by the device 15, and the stock reaches the reaping device 16 and is harvested. Then, the cereal is held by the cereal conveying device 17 and conveyed upward, supplied to the threshing device 11, and subjected to a threshing processing action. In this way, the threshed grains are screened, then cerealed by the first cerealing device 12, sequentially supplied to the Glen tank 1 and stored.
[0020]
In this way, when the threshing operation proceeds, the grain tank 1 stores the grains processed in accordance with the threshing operation and reaches a certain amount, and an alarm is generated by the detection of the full sensor installed in the tank. It is emitted and moves to the grain discharge work.
First, the operator moves the traveling vehicle body 6 to the shore and approaches a truck waiting on the farm road. Next, the grain unloading device 2 makes the grain discharge port 20 at the tip thereof face above the tank of the truck and prepares for the grain discharge operation.
[0021]
During such preparatory work, the telescopic drive device 21 forcibly moves the screwed moving device 24 while driving the motor 23 by a switch operation from the cockpit and causing the helical shaft 22 to rotate forward. Move forward (tip side). Then, the moving device 24 aligns the grain outlet 20 at the tip portion with the upper position of the tank of the truck while extending the moving conveying cylinder 3 integrally connected forward with respect to the base conveying cylinder 19. become. At this time, the harness 5 is drawn by the moving conveyance cylinder 3 that slides in the extending direction with respect to the base conveyance cylinder 19 and is sequentially pulled out from the storage container 25, and can sufficiently cope with the elongation of the grain carrying-out device 2. It can be extended smoothly without any hindrance to the energizing action.
[0022]
The movable transfer cylinder 3 is adjusted to the target position while being expanded and contracted, but the motor 23 may be reversed when it is reduced.
In this way, when the grain carrying-out device 2 completes the positioning of the grain discharge port 22, when the discharge lever is operated, the lifting in the cerealing device 18 is started from the discharge spiral 37 at the bottom of the Glen tank 1. The rotation is started in the order of the grain helix 18a, the conveyance helix 19a in the base conveyance cylinder 19, and the conveyance helix 3a in the moving conveyance cylinder 3. And the grain in the Glen tank 1 is sent to the base conveyance cylinder 19 from the cerealing device 18, and is further inherited by the movement conveyance cylinder 3, and passes through each conveyance spiral 19a, 3a from the grain discharge port 20 outside the machine. To the truck tank.
[0023]
As described above, when the grain carrying out operation is completed, the grain carrying out device 2 performs the switch operation in order to reduce the movable carrying cylinder 3 used in the extended state to the base carrying cylinder 19 side. Then, the motor 23 is reversed. Then, the movable conveying cylinder 3 moves in the contracting direction while sliding on the base conveying cylinder 19. At this time, the harness 5 that has been pulled out receives the contracting action of the spring 26, and the slack portion is stored. It is drawn into the container 25. Accordingly, the harness 5 does not sag even if the movable transfer cylinder 3 is reduced from the extended state, and therefore there is no trouble such as hanging down.
[0024]
As shown in FIG. 7, the angular shaft 3b that supports the conveying spiral 3a so as to be able to transmit is supported by a plurality of bearings 19c.
As shown in FIG. 8, the movable conveying cylinder 3 has an advantage that it is stably supported and guided and can be smoothly expanded and contracted because the guide cylinder 27 is long. Further, since the movable transfer cylinder 3 is configured in the embodiment shown in FIGS. 9 to 13, it has a feature that the expansion and contraction operation can be performed smoothly and stably. In addition, when the support rollers 35a, 35b, and 35c are configured as shown in FIG. 13, the dust is smoothly discharged and the operation is stabilized because the lower rollers avoid a position where dust and the like are accumulated.
[0025]
And if the cutting blade 36 is comprised as shown in FIG. 14, since it can cut | disconnect the long rice cake mixed in the conveyance grain, it does not wind around a rotation part and it works safely. There is a feature that can be.
Further, as shown in FIGS. 15 and 16, the Glen tank 1 is configured such that when the discharge spiral 37 finishes the discharge operation, the stop timing is stopped by setting a predetermined time delay from the closing of the upper shutter 38. did. For this reason, the grains in the series of grain unloading devices 2 are sufficiently discharged to become residual rice.
[0026]
Therefore, the moving conveyance cylinder 3 has an advantage that it can be sufficiently reduced without being affected by the residual rice.
