[0002]

2. Description of the Related Art Conventionally, a combine is provided with a threshing apparatus for threshing a harvested grain culm and a Glen tank for storing and storing the grain after threshing, so that the harvesting and threshing operation can be continuously performed. It has a configuration. And, when the grain that is sequentially stored as the work progresses becomes full, the Glen tank uses a series of grain unloading devices provided as an auxiliary device, and the truck waiting for the stored grain is used. To be carried out to the tank. Then, the grain discharge device is provided with a movable cylinder having a grain discharge port provided at its tip slidably fitted to the fixed cylinder on the base side, and the movable cylinder is arranged along the outside of the fixed cylinder. The structure is configured such that the release position of the grain is adjusted with respect to the machine body by adjusting the extension and retraction by the provided screw shaft for adjustment.

Therefore, the first embodiment has a feature that the harness 41 can always be stored in the winding reel 42 without being loosened.

Next, the operation will be described. First,
The engine is started and the crawler 12 is transmitted while driving the rotating parts of the body to move the traveling body 9 forward. Then
After the culm in the field is weeded by the weeding rod 17, the culm raising device 18 raises the culm in an upright state, and the root reaches the reaper 19 and is cut off. The grain culm is conveyed while being clamped by the grain culm conveying device 20, and is passed on to the feed chain 16 of the threshing device 13. After the cereal culm supplied to the threshing apparatus 13 is subjected to the threshing treatment action, the selected and carefully selected grains are fried by the first fryer and sequentially conveyed to the Glen tank 2. It is stored.

As the harvesting and threshing work proceeds in this way, the grain stored in the grain tank 2 is sequentially stored in the Glen tank 2 and reaches a certain amount. A warning is issued by the detection of, and the operator is notified, so that the cutting and threshing operations are interrupted and the operation is shifted to the grain discharge operation. Then, the operator moves the traveling vehicle body 9 to the ridge and approaches the truck waiting on the farm road. Next, the grain discharge device 3 moves the grain discharge port 7 at the tip thereof to above the tank of the truck so as to face it, and prepares for the grain discharging operation.

At this time, the grain discharge cylinder 5 drives the adjusting motor 11 by operating a switch from the cockpit to drive the screw shaft 3
When the rotating member 5 is rotated, the adjusting tube 37 is adjusted to the outside and the movable tube 8 is moved while sliding on the fixed tube 6 for the threaded screw portion 36, so that the grain discharge port 7 at the tip end portion is moved. Align to the position above the truck tank. The movable cylinder 8 is extended with respect to the fixed cylinder 6 when the adjustment motor 11 is rotated in the normal direction, and is moved in the contracted direction when the adjustment motor 11 is rotated in the reverse direction.

Next, when the discharge lever is operated to enter,
Rotational power reaches the vertical feed screw conveyor 21 of the vertical transport cylinder 4 from the discharge spiral at the bottom of the Glen tank 2, and via the bevel gears 24, 24 ', the horizontal feed screw conveyor 22 of the fixed cylinder 6, the movable cylinder 8 horizontal feed spring conveyor 2
3 is transmitted sequentially. Therefore, the grains in the Glen tank 2 are passed from the starting end of the vertical transport cylinder 4 to the fixed cylinder 6, and further discharged through the movable cylinder 8 from the grain discharge port 7 to the outside of the machine.

In this manner, the grains are continuously conveyed, taken out of the Glen tank 2, and carried out to the truck tank. In this way, when a series of grain unloading operations are completed, the grain unloading cylinder 5 rotates the movable cylinder 8 used in the extended state by rotating the adjusting motor 11 in the reverse direction, thereby turning the screw shaft 35. Then, it is reduced to the fixed cylinder 6 side through an adjusting pipe 37 having a screw portion 36, and is supported by a support device 38 on the threshing device 13 to stand by.

As described above, the grain discharging device 3 according to the present invention comprises the adjusting device 10 for adjusting the distance of the grain discharging port 7.
Is provided through the inside of the grain carry-out cylinder 5, so that the one that can perform the adjustment operation accurately can be manufactured at a low cost, and the appearance can be summarized in a neat configuration. Things.
