[Industrial application fields]
The present invention relates to a harvesting / threshing device for a combine.
[0002]
[Prior art]
In the combine, the finely selected grain (first) threshed by the threshing apparatus is temporarily stored in a grain tank that is opposed to the threshing apparatus. Thus, the supply to the grain tank is fried in a frying cylinder from the harvest outlet provided in the threshing device and put into the upper part of the grain tank. On the other hand, the opposite location of the threshing device where the grain tank is installed is a narrow space immediately after the engine bonnet and the seat.
[0003]
FIG. 3 is a partial side view of the conventional example around the grain tank. Here, a is a grain tank, which is provided immediately after the engine bonnet and the seat seat b in a threshing device (not shown). It is provided as an elongated container in a limited space. In addition, c is the whipping cylinder which lifts the threshing grain from the threshing device to the grain tank a, d is the vertical auger which feeds the grain in the grain tank a, and e is fed by the vertical auger d. It is a horizontal auger that feeds and discharges grains.
[0004]
[Problems to be solved by the invention]
If the grain tank a is provided in such a space in such a shape, its volume must be extremely small. The vertical auger d is rotated horizontally and the horizontal auger e is moved up and down, but the expansion cylinder f for moving the horizontal auger e up and down is at the corner of the grain tank a where the vertical auger d and the horizontal auger e intersect. Since it is provided, the volume of the grain tank a is further reduced. In addition, when the volume of the grain tank a is small, there exists a possibility that it may become full when the conveyance vehicle which piles up the cerealed grain changes.
The present invention solves such a problem, and is designed to ensure a sufficient volume by contriving the shape of the grain tank.
[0005]
[Means for Solving the Problems]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a combine grain threshing device showing an example of the present invention, and FIG. 2 is a plan view. The combine grain threshing device is a threshed grain by a threshing device (not shown). It consists of a grain tank 10 that stores grains, a vertical auger 12 that feeds up grains in the grain tank 10, and a horizontal auger 14 that feeds and discharges grains fed up by the vertical auger 12. .
[0007]
In these arrangements, the threshing device is arranged on the left side of the rear part of the machine body frame 16, and the grain tank 10 is arranged on the right side of the rear part opposite thereto. The grain tank 10 is a tall and slender container that stands on the body frame 16. The grain tank 10 is often made of metal, but recently, it may be manufactured by blow molding a resin. An engine bonnet 18 and a seat seat 20 are provided in front of the grain tank 10. Since the longitudinal length of the machine body frame 16 is limited, the grain tank 10 and the engine 18 are arranged in a complicated manner.
[0008]
The vertical auger 12 is erected at the center of the rear part of the grain tank 10 with 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 this gear 24 can be driven by a rack that is reciprocated by a hydraulic cylinder or the like (not shown) so that the vertical auger 12 rotates horizontally. it can.
[0009]
The horizontal auger 14 has a rear end connected to the upper portion of the vertical auger 12 so as to be movable up and down, and a front portion extends forward. And in the middle, it is supported by the horizontal auger rest 26 attached to the upper part of the cereal cylinder mentioned later. In this case, a stay 28 is extended to the side of the horizontal auger 14, and an extendable cylinder 30 is interposed between the stay 28 and the vertical auger 12.
[0010]
Therefore, the horizontal auger 14 can be moved up and down by expanding and contracting the telescopic cylinder 30. The telescopic cylinder 30 is a hydraulic / pneumatic cylinder or an electric cylinder, but an electric cylinder is preferable in consideration of piping and the like.
[0011]
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 a few large-diameter pipes can be molded by blow molding, so it is preferable to replace them with resin products from the viewpoint of weight and cost. .
[0012]
The grain that has been threshed by the threshing device is taken out from the mashing port 32, and fried upward by a lifting cylinder 34 that is erected on the side of the grain tank 10 so as to face the threshing device. It is thrown in from the spout 36 provided in the upper part. The grain stored in the grain tank 10 is taken out from the take-out port 38 provided at the lower part thereof and fed by the vertical auger 12.
[0013]
The grain that has been fed up by the vertical auger 12 is handed over to the horizontal auger 14 and fed laterally, and is discharged from the grain outlet (not shown) at the tip. The grain discharged from the grain outlet is loaded on a transport vehicle or the like waiting below.
[0014]
When the combine runs while cutting and threshing, the grain discharged from the horizontal auger 14 is loaded on a traveling vehicle or the like that is running side by side. Therefore, as described above, the vertical auger 12 needs to be rotated horizontally and the horizontal auger 14 needs to be moved up and down for the positioning and the like.
[0015]
Transportation vehicles, etc. must be replaced when they are full. Considering the idle time at this time, the larger the capacity of the grain tank 10, the better. However, as described above, the space is limited and cannot be increased unnecessarily. The present invention solves this by configuring the grain tank 10 as follows.
[0016]
First, although it is the shape of the front, the upper part is swollen forward from the vicinity of the upper part of the engine bonnet 18 present in the front so as not to obstruct the driver's driving. Moreover, about the upper shape, the upper part is made higher than this in the range which the horizontal auger 14 does not rotate.
[0017]
If the spout 36 is not set substantially at the center of the front and rear of the grain tank 10, the piles of grain dropped from now on become uneven and a sufficient storage amount cannot be secured. Therefore, as the front part of the grain tank 10 bulges forward, the spout 36 must also move forward. On the other hand, since the position of the threshing port 32 of the threshing device is determined, the whipping cylinder 34 is inclined forward.
[0018]
By adopting such a configuration, the above-described lateral augerest 26 inevitably moves forward. Accordingly, it is possible to support the front side of the horizontal auger 14, and there is an advantage that the deformation of the horizontal auger 14 can be suppressed and the horizontal auger rest 26 can be configured with a low strength.
[0019]
【The invention's effect】
As described above, the present invention is as described above, that is, the upper front part of the grain tank is expanded above the engine, and the upper part of the range not interfering with the grain tank is higher than the bottom surface of the grain tank. As a result, the volume of the grain tank can be increased. In this case, the upper rear part of the grain tank has a corner cut out due to the provision of the telescopic cylinder, but this is compensated by the front bulging. As a result, the upper and lower parts of the grain tank have approximately the same front-rear width and are balanced.
