DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dumping auger for taking out grains stored in a grain tank of a combine.

[0002]

2. Description of the Related Art Conventionally, combine dumping augers have been used.
A type that expands and contracts is considered.

[0003]

In the form of expanding and contracting the auger auger of the combine, in order to increase the effective expansion and contraction length, the expansion and contraction of the expansion and contraction helical cylinder with respect to the horizontal helical cylinder provided on the vertical helical cylinder side. Must be set to the full length.

[0004]

According to the present invention, a transfer cylinder 4 rotatable around a horizontal axis 3 is provided at the upper end of a vertical spiral cylinder 2 for pumping grains from a Glen tank 1. In order to integrally connect the horizontal spiral cylinder 6 to the transfer cylinder 4, the transfer cylinder 4
Alternatively, a plate 5 is integrally provided on an end surface of a horizontal spiral cylinder 6
And then, the pre - is protruded the door 5 upwards to the side, to the plate 5, combine made by attaching a motor M for driving the ball screw shaft 8 stretching spiral sleeve 7 to extend and retract relative to the transverse helical tube 6 The structure of the ash auger.

When the grains harvested and stored in the Glen tank 1 by the combine operation are taken out of the machine, the screw shaft 8 is rotated by the drive of the motor M so that the discharge end of the end of the horizontal spiral cylinder 6 is directed in the take-out direction. Then, the telescopic helical cylinder 7 is extended and the discharge port is viewed above the discharge position. The spirals in the spiral cylinders 2, 6, and 7 are rotated to transfer and discharge the grains. or,
When returning the dumping auger to the storage position after the discharge of the grains, the screw shaft 8 is rotated in reverse by the drive of the motor M, and the telescopic spiral cylinder 7 is retracted over the base of the horizontal spiral cylinder 6.

[0006]

According to the present invention, the combine harvesting auger can be used.
The motor M for driving the screw shaft 8 is connected to the transfer cylinder 4 or the side screw.
Since the screw shaft 8 is attached to the plate 5 provided integrally with the end surface of the spiral cylinder 6, the effective length of the screw shaft 8 is formed from the proximal end of the horizontal spiral cylinder 6, and the proximal end of the telescopic spiral cylinder 7 extends horizontally. It can be shortened so as to be located at the base end of the spiral cylinder 6,
Thereby, the total length of the horizontal spiral cylinder can be shortened, and the elastic length of the telescopic spiral cylinder 7 can be set long, and the weight can be reduced, and stable drainage can be performed.

BEST MODE FOR CARRYING OUT THE INVENTION A combine harvester mounts or supports a threshing device 11, a mowing device 12, a cockpit 13, an engine E, a Glen tank 1 and the like on a chassis 10 having a crawler 9, and the mowing device 12 performs mowing. The grain culm is conveyed to the threshing device 11 to thresh, and the threshed grains are stored in the grain tank 1 on the side. A spiral 14 extending in the front-rear direction is provided at the bottom of the Glen tank 1 so that the spiral 14 can be transmitted from the engine E side via a transmission clutch.

The vertical helical cylinder 2 is provided on the rear side of the Glen tank 1 so as to extend in the vertical direction. The vertical helical cylinder 2 can be driven to rotate around the vertical axis so that the discharge direction can be selected.
A spiral 24 is provided in the vertical spiral cylinder 2 and the spiral 1
It is configured to rotate interlockingly from the four sides.

The transfer cylinder 4 is connected to the upper end side of the vertical spiral cylinder 2 so as to be rotatable around a horizontal axis 3, and the transfer cylinder 4 is integrally connected to a horizontal spiral cylinder 6. Thus, the vertical spiral angle of the horizontal spiral cylinder 6 can be adjusted by rotating the horizontal spiral cylinder 6 in the vertical direction around the horizontal axis 3 together with the transfer cylinder 4. This vertical angle is set by an extendable telescopic cylinder 15 provided between the vertical helical cylinder 2 and an arm 34 integral with the plate 5 on the transfer cylinder 4 side.

[0010] The plate 5 is the transfer cylinder 4 or the horizontal spiral cylinder.
Integrally provided on an end face of 6, is protruded upward to the side, provided with a bearing 16 for bearing the threaded shaft 8 in the plate 5, it is attached to position the electric motor M to Inherit cylinder 4 side. The forward and reverse rotations of the motor M cause the screw shaft 8 to rotate forward and reverse, thereby expanding and contracting the telescopic spiral cylinder 7 fitted to the outer periphery of the horizontal spiral cylinder 6.

A lead metal 17 into which the screw shaft 8 is screwed and a guide roller 18
Is provided. The guide roller 18 is on the opposite side of the lead metal 17 and can rotate while sliding on the peripheral surface of the horizontal spiral cylinder 6.
A discharge port 19 is provided on the tip end side.

[0012] Spirals 25 and 26 for conveying grains are provided along the inside of the horizontal spiral cylinder 6 and the telescopic spiral cylinder 7, and these spirals 25 and 26 are also extended and contracted as the telescopic spiral cylinder 7 expands and contracts. It has a configuration. These spirals 25 and 26 are interlocked and rotated from the spiral 24 in the vertical spiral cylinder 2 via a bevel gear, the shaft 3 in the transfer cylinder 4 and the like.

The screw shaft 8 is rotated by the drive of the motor M to extend and retract the spiral tube 7 with respect to the horizontal spiral tube 6 to adjust the position of the outlet 17. Reference numeral 20 denotes a ring provided on the outer peripheral surface of the distal end of the horizontal spiral cylinder 6, and reference numeral 21 denotes a ring provided on the inner peripheral surface of the proximal end of the expandable spiral cylinder 7, which is configured to smoothly perform expansion and contraction sliding.

The vertical spiral cylinder 6 and the telescopic spiral cylinder 7 are vertically angled by the telescopic ring 15, and the vertical spiral cylinder 2 is turned.
The rotation is performed. In FIG. 4, the point different from the above example is that the collar 22 integral with the plate 5 is fixed so as to be fitted to the outer peripheral portion of the base end of the horizontal spiral tube 6 to reinforce the connecting portion of the horizontal spiral tube 6. The sliding portion of the guide roller 18 below the collar 22 is a notch 2
As a third mode, the guide roller 18 is brought into sliding contact with the peripheral surface of the horizontal spiral cylinder 6 directly.

In FIG. 5, the difference from the above example is that the O-ring 27
In order to prevent grain leakage between the outer periphery of the horizontal spiral cylinder 6 and the inner peripheral surface of the telescopic spiral cylinder 7 and to join 29 of the cylindrical body formed on the inner peripheral surface of the telescopic spiral cylinder 7 The sliding contact damage of the surface of the ring 20 due to the beat 28 as the weld overlay is eliminated.

In FIG. 6, a different point from the above example is that a guide rail 30 having a concave cross section for slidingly guiding the guide roller 18 at the base end of the telescopic spiral cylinder 7 is provided on the outer peripheral surface of the horizontal spiral cylinder 6. Things. The guide rail 30 is plated to eliminate paint peeling. Reference numeral 31 denotes a bolt for fixing the end of the rail 30 to the plate 5 side, and reference numeral 32 denotes a fixing piece for pushing the front end of the rail 30 into a gap 33 formed inside the ring 20 to hold it.
