The structure of the discharge auger 10 is such that a vertical cylinder 11 is provided on the machine body side so as to be rotatable about the vertical axis by a cylinder or the like, and the base of the horizontal cylinder 13 is attached to the upper end of the vertical cylinder 11 so that the auger can be moved up and down with respect to the vertical cylinder 11. It is mounted so that it can freely rotate up and down using a cylinder 12.

A discharge part 14 is formed at the tip of the horizontal tube 13, and the discharge part 14 is made to protrude long forward beyond a driver's seat 15 provided on the front side of the threshing device 3 to facilitate grain discharge work.

The horizontal tube 13 is also rotatable in the left and right directions due to the rotation of the vertical tube 11, and the rotation of the horizontal tube 13 in the left and right direction is controlled by the rotation of the vertical tube 11.
It may be configured to rotate 360 degrees around , or it may be configured to rotate except above the driver's seat 15.

An intermediate support device 16 for supporting the intermediate portion of the horizontal tube 13 is provided on the top surface of the threshing device 3 or in the vicinity thereof or at the driver's seat 15.

In this embodiment, the intermediate support device 16 is provided on the side plate 17 of the driver's seat 15. The intermediate support device 16 fixes the upper end of the arm portion 19 to the lower part of the gutter-shaped receiving member 18 . Arm part 19
is bent to the side in the middle, and the movable part foundation is fixed to the side end.

The receiving member 18 is provided with a locking body n that elastically presses the upper surface of the horizontal tube 13 placed on the receiving member 18.

The intermediate portion support device 16 includes the receiving member 18, an arm portion 19 that connects the receiving member 18 and the moving member J, and the locking body n, and connects the moving member 20 to the side plate!
It is attached to the vertical change means 21 provided at 7 so that the vertical position can be changed freely, and is configured to be switchable between a low non-working position and a high working position, and supports the discharge auger 10 at each position.

A lower horizontal axis η is fixed at the lower part of the moving member 20, and an upper horizontal axis n is fixed at a position above the lower horizontal axis n.

The vertical change means 21 has a long lower hole 24 that is vertically long.
An upper elongated hole 6 is formed which is located at an upper side position of the lower elongated hole 24 and is substantially parallel to the lower elongated hole 24. The lower horizontal shaft n is attached to the lower long hole 24 so that only vertical movement is possible.
The upper horizontal shaft n is attached to the upper long hole δ so that it can move freely only up and down.

At the upper end of the upper elongated hole B, an engagement groove portion of one shape is connected. Therefore, the distance between the moving members is the lower horizontal axis η
moves up and down inside the lower long hole 24, and the lower horizontal axis n moves up and down inside the upper long hole δ, respectively.

When the upper horizontal shaft n engages with the engagement groove 9 through the upper elongated hole 3, the moving member 20 is prevented from moving horizontally and downwardly, and the intermediate portion support'? 16 is held in the working position.

Switching between the non-working position and the working position of the intermediate part support device 16 is performed by a locking member n provided on the receiving member 18 that elastically presses the upper surface of the horizontal cylinder 13. With the vertical movement of the intermediate part support fi1
6 is moved up and down with respect to the up and down changing means 21.

2 is an elastic member provided on the inner surface of the receiving member 18 to protect the horizontal tube 13.

(effect) Next, we will discuss the effect.

The present invention has the above-mentioned configuration, and on the side of the driver's seat 15,
An intermediate support M16 is provided to support an intermediate portion of the horizontal tube 13 of the discharge auger 10.

Since the intermediate support device 16 is attached to be switchable between a low non-working position and a high working position by the vertical change means 21, the discharge auger 10 can be operated with the intermediate support device N16 in the low non-working position. It is supported and fixed on the road 1 running f and is locked by the locking body n, and reaches the field.

In this case, since the receiving surface of the receiving member 18 of the intermediate support device 16 is provided with an elastic base, vibration damage to the horizontal tube 13 is prevented.

Further, since the receiving member 18 of the intermediate support device 16 is provided with a locking body n for fixing the horizontal tube 13 of the discharge auger 10 placed on the receiving member 18, the locking body n The horizontal tube mouth is fixed to the receiving member 18, and the vehicle can travel safely.

When arriving at the field, in preparation for discharging grain after reaping and threshing, the auger upper and lower cylinders are extended and the horizontal cylinder 13 of the discharge auger 10 is moved upward, but the upper surface of the horizontal cylinder 13 is connected to the locking body. Since the intermediate support device 16 is fixed to the receiving member 18 by the horizontal tube 13, the intermediate support device 16 moves upward together with the horizontal tube 13.
The lower horizontal axis η between the moving members moves upward in the lower long hole 24 of the vertical changing means 21, and the upper horizontal axis n between the moving members moves upward in the upper long hole δ of the vertical changing means 21. By applying the member, the intermediate support member 16 is moved upward to the working position for discharging grains.

Since a q-shaped engagement groove is formed at the upper end of the upper elongated hole B, the vertical cylinder 11 is rotated by the rotary cylinder, the horizontal cylinder 13 is rotated laterally, and then the horizontal cylinder 13 is rotated slightly downward. When moved, the upper horizontal axis n of the moving member π engages with the engagement groove 9. Therefore, the intermediate support M16 is switched to the non-working position and fixed by the vertical movement of the horizontal tube 13.

When one machine moves forward in this state, it divides the grass with the weed body 5, rakes the shell culm with the raking reel 6, reaps the shell culm with the sliding motion of the cutting blade 7, and makes a threshing bag! Hull culms are supplied to i3 and threshed in the threshing device 3, and when a certain amount of grain has been threshed, the machine is moved to a light truck waiting near the field.

Then, when the locking body n of the intermediate part support device 16 is removed, the horizontal cylinder 13 of the discharge auger 10 becomes free with respect to the intermediate part support device 16, so the auger upper and lower cylinders 12 move it slightly upward, and then Vertical cylinder 1 by expanding and contracting the rotating cylinder
1 is rotated, the discharge part 14 of the horizontal tube 13 is located at an arbitrary position, and the grain is conveyed from the discharge part 14 to the tank of the light truck.

When the grain discharge work is completed, the horizontal tube 13 is rotated and positioned above the intermediate support device 16, and the auger upper and lower cylinders 12 move the horizontal tube 13 downward.

Place the horizontal tube 13 on top of the receiving member of the intermediate support device 16,
Subsequently, when a certain amount of grain is threshed during the reaping and threshing operation, the grain is discharged into the tank of the light truck by the discharge auger 10 as described above.

In this case, since the intermediate support device 16 is located at a high working position, the work of storing the horizontal tube 13 of the discharge auger 10 can be done quickly and the work becomes easy.

Then, when the work in the i field is completed.

The horizontal tube 13 of the discharge auger 10 is placed on the receiving member 18 of the intermediate support device fi16, fixed by the locking body n, and the horizontal tube 1
The intermediate support device 16 is moved downward so that the discharge auger 10 is located in the non-working position, and the vehicle travels on the road while supporting the horizontal tube 13 of the discharge auger 10 at the low non-working position by the intermediate support device 16.

(Effects) The discharge auger of the combine is placed in a low position to make it easy to drive on the road, and in the field it is placed in a high position so that it can be easily turned and discharged to discharge grain onto the truck bed. Therefore, conventionally, a threshing device having a frame having a traveling device at the lower part and a discharge auger at the upper position provided on the frame,

A vertical movement mechanism and a turning mechanism for the discharge auger 10, which are provided in the discharge auger 10.

An intermediate support device 16 of the discharge auger 10 is provided directly on or in the vicinity of the upper surface of the threshing bag M3, and the intermediate support device 16 is moved up and down to move the discharge auger 10 between the road traveling position and the grain. In the grain discharge device for a combine harvester, the grain discharge device for a combine has a means 21 for vertically changing the intermediate portion support device 16 to change the intermediate portion support device 16 to the discharge position!
Reference numeral 6 denotes a gutter-shaped receiving member 18 that receives the lower surface side of the discharge auger 10 at a lower level, and a locking IE body 2 that locks the upper surface side of the discharge auger 10 that is attached to the receiving member 18.
7 and the discharge o whose upper surface side is locked by the locking body n move -10 upward by the vertical movement mechanism, the receiving member 18 integrally moves up to the grain discharge position and remains at that position. Since it is a grain discharge device for a combine harvester that is configured to be fixed, it is an intermediate support device! By vertically moving the discharge auger 10, the discharge auger 10 can be easily switched between supporting it in a low non-working position and supporting it in a high working position.
