Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain discharging apparatus.

[0002]

2. Description of the Related Art In a combine, threshed grains are temporarily stored in a grain tank, and the grains in the grain tank are combined with a vertical auger.
With the horizontal auger connected to this, the grain is taken into a carrier that runs in parallel with the combine. In this case, the position of the grain-removing port at the tip of the horizontal auger must be changed according to the position of the carrier, etc., so the vertical auger can rotate horizontally,
The horizontal auger is vertically movable.

The rotation of the vertical auger and the horizontal auger is as follows:
0-125840 and JP-A-60-244708.
As can be seen in the publication, a gear and a rack are provided between the vertical auger and the grain tank, and a telescopic cylinder is provided between the horizontal auger and the vertical auger. FIG. 3 is a partial side view of the grain discharging device according to the above-mentioned prior example. In this case, the telescopic cylinder a has the grain tank d inside the corner where the vertical auger b and the horizontal auger c intersect. Part of it is cut away.

[0004]

With such a structure, the grain tank not only has its volume reduced by the presence of the telescopic cylinder, but also interferes with each other and limits the rotation angle of the vertical auger. It will be. The present invention solves such a problem by positioning the telescopic cylinder behind the vertical auger.

[0005]

[Means for Solving the Problems] Under the above problems, the present invention provides a grain tank for storing grains threshed by a threshing device, and a grain tank provided behind the grain tank so as to be horizontally rotatable. A combine of a vertical auger that lifts the grains inside, and a horizontal auger that is vertically movably connected to the upper part of the vertical auger and horizontally transports and discharges the grains conveyed by the vertical auger. In the grain discharging device, a stay projecting rearward from the vertical auger is extended to the rear part of the horizontal auger, and a telescopic cylinder for vertical movement of the horizontal auger is interposed between the stay and the vertical auger. The present invention provides a grain discharging device.

Further, according to the present invention, in the above means, the upper part of the grain tank is bulged into the space above the member existing in front of the grain tank. Provided are grain combiners for combine harvesters, which are characterized in that grains, vertical augers, and horizontal augers are made of resin pipes.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a combine grain discharging apparatus showing an example of the present invention, and FIG. 2 is a plan view.
The grain discharging device of the combine is composed of a grain tank 10 for storing grains threshed by a threshing device (not shown), a vertical auger 12 for lifting the grains in the grain tank 10 upward, and a vertical auger 12. It consists of a horizontal auger 14 for laterally transferring and discharging the grains that have been pumped.

In these arrangements, the threshing device is arranged on the left side of the rear part of the machine frame 16, and the grain tank 10 is arranged on the right side of the rear part facing the threshing device. The grain tank 10 is a tall and elongated container that stands on the body frame 16. The recent grain tank 10 is often manufactured by blow molding a resin. An engine hood 18 and a seat 20 are provided in front of the grain tank 10.
Since the front and rear length of the body frame 16 is limited, the grain tank 10 and the engine bonnet 18 are arranged in a complicated manner.

The vertical auger 12 is erected at the center of the rear portion of the grain tank 10 while being supported by a support bracket 22 or the like. A gear 24 is attached to the outer periphery in the middle of the vertical auger 12, and the gear 24 can be driven by a rack that can be reciprocated by a hydraulic cylinder or the like (not shown), whereby the vertical auger 12 rotates horizontally. it can.

The horizontal auger 14 has a rear end connected to the upper part of the vertical auger 12 by flange coupling or the like so as to be vertically movable, and a front part extends forward (supported midway by an auger rest 26). A stay 28 protruding rearward from the vertical auger 12 is provided at the rear portion of the horizontal auger 14, and the telescopic cylinder 3 is provided between the stay 28 and the vertical auger 12.
0 is inserted.

With this structure, the lateral auger 14 can be moved up and down by expanding and contracting the telescopic cylinder 30. The telescopic cylinder 30 may be a hydraulic / pneumatic cylinder or an electric cylinder, but an electric cylinder is preferable in consideration of piping and the like.

The cylindrical portions of the vertical auger 12 and the horizontal auger 14 are conventionally made of metal pipes and are very heavy. However, recently, even with a slightly large diameter pipe, it is possible to mold strong ones by blow molding, so it is preferable to substitute these with resin products in terms of weight and cost. .

The grains that have been threshed by the threshing device are taken out from the grain harvesting port 32 and face the threshing device and the grain tank 1
It is fried upward by a fried cylinder 34 which is erected on the side surface of No. 0, and is thrown in through a slot 36 provided in the upper part of the grain tank 10. The grain stored in the grain tank 10 is taken out from the take-out port 38 provided in the lower part and is fried by the vertical auger 12.

Grains fried by the vertical auger 12 are taken over by the horizontal auger 14 and transferred in the horizontal direction, and are discharged from a grain discharging port (not shown) at the tip thereof. The grains discharged from the grain discharging port are loaded into a truck or the like waiting underneath.

When the combine travels while performing the cutting and threshing work, the grains discharged from the horizontal auger 14 are transferred to a carrier vehicle or the like running in parallel. Therefore, as described above, the vertical auger 12 needs to rotate horizontally and the horizontal auger 14 needs to move up and down in order to adjust its position.

When a truck is full, it must be replaced. Considering the idle time at this time, the larger the capacity of the grain tank 10, the better. However, as mentioned above, there is a space limitation and it cannot be made too large. On the other hand, with the vertical auger 12 and the horizontal auger 14 having the above-described configurations, the grain tank 10 can be configured as follows in the present invention.

First, although it has a front shape, the upper portion can be bulged forward toward the space above the engine hood 18 existing in the front. Next, as for the rear shape, since the telescopic cylinder is not provided at the corner where the vertical auger 12 and the horizontal auger 14 intersect, this part of the container can be used as a grain tank. Further, the rear portion outside the operating range of the vertical auger 12 and the horizontal auger 14 (A in FIG. 2)
Can be formed in the tank. Further, regarding the upper shape, the upper portion thereof can be made higher than this in a range where the horizontal auger 14 does not rotate.

[0018]

As described above, according to the present invention, the telescopic cylinder for moving the horizontal auger up and down is brought to the rear of the grain tank and is not provided at the intersection of the vertical auger and the horizontal auger. Therefore, this portion can be formed in the grain tank. Therefore, the volume of the grain tank can be increased. Further, since the telescopic cylinder portion is exposed, maintenance and the like thereof are also advantageous. In addition, the position of the fried cylinder can be freely set in the front and back.
