DESCRIPTION OF THE PREFERRED EMBODIMENTS The combine is a chassis 6 having a crawler 47.
A cutting device 7 for cutting and transporting grain culm thereon, a threshing device 8 for receiving and threshing the transported grain culm, a Glen tank 9 for accommodating threshed grains, and a bottom auger 10 at the bottom of the Glen tank 9 There are provided a vertical auger 11 for transporting grains discharged rearward upward, and a grain auger 12 connected to the upper end and capable of transporting grains in the horizontal direction. 13 is a cockpit.

The vertical auger 11 can be swiveled, and the dumping auger 1
2 can be determined in the horizontal direction, and the dumping auger 12 can be vertically angled by the telescopic cylinder 14 at the upper end. The vertical auger 11 and the bottom auger 10 have a spiral interior. The dumping auger 12 has a base tube 15 connected on the vertical auger 11 and a zoom tube 16 which can be fitted and contracted on the outer periphery of the distal end side. A helical shaft 18 having a helical shaft 17 is mounted inside the zoom cylinder 16.
A helical shaft 14 composed of an extendable and retractable shaft and a spline shaft is fitted around the shaft 8 so as to be able to expand and contract integrally with the zoom cylinder 16.

A helical boss 2 of a fixed length is inserted along the helical shaft 14 so as to be movable in the direction of the helical shaft 14 but integrally rotate in the direction of rotation. . The spiral boss 2 includes a spiral cylinder 25 that forms the spiral 1 on the outer periphery.
Has a large diameter, and a connecting metal 26 is attached to one end of the spiral cylinder 25.
The small-diameter shaft cylinder 5 is connected via the. A dustproof seal 27 having a diameter capable of fitting and sliding on the inner peripheral surface of the spiral cylinder 25 is fixedly provided on the outer peripheral portion of the shaft cylinder 5, and a stopper having a diameter slightly smaller than that of the dustproof seal 27 is provided at the tip end. A ring 28 is provided, and a notch 29 is provided in the stopper ring 28.

In addition, bearing holes 44 and 45 are formed on the inner circumferences of the front and rear metals 26 and 28 so as to be slidable in the axial direction by being fitted to a helical shaft 4 formed of a hexagonal shaft. The screw bosses 2 to be fitted are configured to rotate integrally. A stopper pin 46 is provided at the distal end of the spiral cylinder 25 to prevent the spiral cylinder 25 from slipping inward. The notch 29 of the stopper ring 28 is aligned with the stopper pin 28 so that the spiral cylinder 25 between the opposed spiral bosses 2 has a shaft cylinder. 5 is a configuration that can be fitted. The shaft cylinder 5 is fitted into the spiral cylinder 25, and the phase of the notch 29 of the stopper ring 28 and the phase of the stopper pin 46 are shifted.
Each spiral boss 2 is fitted to the spiral shaft 4.

The expansion and contraction of each spiral boss 2 in the axial direction is performed while being restricted between the stopper ring 28 to which the stopper pin 46 is fitted and the dustproof seal 27. Further, by shortening the zoom cylinder 16, the spiral shaft 4 and the spiral boss 2 are shortened. However, a grain transport resistance acts on the spiral boss 2, and the spiral boss 2 is located on the side of the spiral 17 on the back side. It expands and contracts sequentially from the spiral boss 2. In the shortest state, the stopper pin 46 of each spiral boss 2 is locked to the dustproof seal 27.

In the illustrated example, a spring is not used for expanding and contracting between the spiral bosses 2. However, a spring is provided between the spiral bosses 2 so that the spiral boss 2 is always stretched in the direction of extension or contraction. Is also good. In this case, if the spring is provided in the spiral cylinder 25 to cover the spring, contact friction with the grain can be eliminated. Reference numeral 19 denotes a discharge port at the tip of the zoom cylinder 16, reference numeral 20 denotes a screw rod which expands and contracts the zoom cylinder 16 with respect to the base cylinder 15, rotatably supports the bracket 22 of the base cylinder 15, and is driven by forward and reverse rotation of the motor M1. The distal end is screwed into the bracket 21 on the zoom cylinder 16 side. Reference numeral 23 denotes a bearing metal, which is provided in the distal end of the base cylinder 5 and bears the distal end of the spiral shaft 18.

A slide cylinder 24 having a slightly larger diameter is provided at the distal end of the base cylinder 5, and the zoom cylinder 16 is fitted over the outer periphery of these slide cylinders 24 to smoothly extend and contract.
The bearing metal 23 is attached to the inner periphery of the slide cylinder 24 on the distal end side. In FIG. 4, the difference from the above example is that in the configuration in which the spring 3 is interposed between the spiral bosses 2 having the spiral 1 formed on the peripheral surface in the axial direction, the length A of the boss portion of the spiral boss 2 is It is shorter than the length B of 3 parts,
The length of expansion and contraction of the spring 3 is increased, and the interval between the spirals 1, that is, the cut portion of the spiral 1 is shortened.
The spiral 1 of each spiral boss 2 is formed so as to protrude longer than the front end face or the rear end face of the boss portion, and the spring 3 is interposed between the boss end faces.

FIG. 5 is different from the above example in that the telescopic cylinder 1 for changing the vertical angle of the dumping auger 12 is used.
(4) A pin 31 is attached to the distal end of the arm 30 protruding with an appropriate interval C formed at the side of the proximal end of the base cylinder 15 at the distal end.
With the expansion and contraction of the telescopic cylinder 14, the fluffing auger 12 can be controlled to rotate vertically with respect to the upper end of the vertical auger. When the zoom barrel 16 is expanded and contracted with respect to the base barrel 15, an interval C between the base end of the base barrel 15 and the side arm 30 is formed so that the zoom barrel 16 can come and go. The length of expansion and contraction of the zoom cylinder 16 can be set large, and the length of the base cylinder 15 can be set short. In addition, since the arm 30 can be protruded long along the base cylinder 15 side, the load caused by the telescopic cylinder 14 can be reduced,
Stable ascent and descent can be performed.

Outside the arm 30, a reinforcing arm 32 is provided. The distal end of the arm 32 is connected by the pin 31, but the base end is fixed to a shaft 33 which is the center of rotation of the grain discharging auger 12 with respect to the vertical auger 11. Rotate up and down. 6, the difference from the above example is that the vertical auger 1
The upper portion of the holder 36 is rotatable and rotatable with respect to the side surface of the culm cover 35 that covers the culm chamber 34 for discharging the threshed culm.
Mounting support. The configuration is simple, and no special support frame configuration is required.

The threshing device 8 is provided with a feed chain 38 on one side of a threshing room in which a handling cylinder 37 is provided, and threshing while inheriting the grain culm transported from the cutting device 7 in the front and transporting it backward. On the rear side of the threshing room, the threshed culm is inherited from the feed chain 38 and the rear culm cutter 3
A culm chain 40 to be transported to the culm chain 9 is provided.
The upper side of the spike side of the culm chamber 34 having 0 is covered with a culm cover 35. Reference numeral 41 denotes a culm cover for covering the upper side of the root of the culm chamber 34, and a threshing cover 42 for covering an upper part of the threshing chamber.
It can be opened and closed as a series of integrated configurations.

The vertical auger 12 is located on the rear side of the Glen tank 9 and has an upper end dumping auger 1 by a swing motor M2.
The swivel unit 12 is swung horizontally with the vertical auger 12.
Is supported on the outer surface of the culm cover 35 by a holder 36. The vertical auger 12 is mounted on the holder 36.
It is supported rotatably with respect to. 43 is a threshing device 8
With the top end into Glen Tank 9,
Threshing grains can be fried to the Glen tank 9.
