Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine that continuously performs a harvesting operation for cutting and threshing a culm, for example.

[0002]

Conventionally, a grain tank is provided on a paddy cradle behind the driver's seat, and the grain tank and the paddy bag to be installed at an outlet below the grain tank are provided. In the structure for collecting grains, in order to increase the capacity of the grain tank, it is necessary to form the tank upper surface high due to dimensional restrictions in front and rear and left and right directions, but the grain tank is formed by a hard synthetic resin or an iron plate or the like. By doing so, there is a problem that the grain tank which has become bulky due to the capacity securing narrows the worker's rear view from the driver's seat, and the grain tank has a larger capacity, a lighter weight and lower cost, and a worker's rear view. There is a problem that it is not possible to easily secure them.

[0003]

According to the present invention, a grain tank is provided on a paddy stand on the rear side of a driver's seat, and the grain tank and the paddy are installed at an outlet below the grain tank. In a combine for collecting grains in a bag, the grain tank is formed so as to be freely foldable by a cloth bag, and even if the upper surface side of the grain tank is raised to increase the capacity, grains are contained. When not in use, the bulk of the grain tank can be lowered to widen the rear view of the operator from the driver's seat, easily secure the rear view of the operator, and reduce the weight and weight compared to those made of synthetic resin or iron plate. The cost can be easily reduced, and the capacity of the grain tank can be easily expanded even if the width in the front-rear and left-right directions is limited, and the operation operability and the harvest workability can be easily improved. is there.

In addition, the bottom of the grain tank is contracted by elastic force to form a bottom inclination angle larger than the angle of repose of the grain, and the bottom of the grain tank is bulged against the contraction force by the weight of the input grain. When the grain is introduced, the inclination of the bottom of the grain tank becomes smaller than the angle of repose of the grain and the capacity of the grain tank can be increased, and when the amount of the grain inside the grain tank is reduced, the bottom of the grain tank is decreased. The inclination becomes larger than the grain angle of repose, the grains can slide down by their own weight in the direction of the take-out port, and the capacity of the grain tank can be easily increased and the harvesting workability can be easily improved.

It is possible to improve driving operability and harvesting workability.

Further, as shown in FIGS. 7, 8, and 9, two push pipes (36) are fixed to the bottom portion (31) of the grain tank (19) so as to face each other and are substantially parallel to each other. The two ends of the pipe (36) are connected by two coil springs (37), and as shown in FIGS. 7 and 9, the weight of the grain put into the grain tank (19) resists the compression of the coil spring (37). Extend the tank bottom (31) to the grain tank (1
9) While securing the capacity, as shown in FIGS. 8 and 9, the paddy bags (3) are removed from the grain tank (19) through the outlet (32).
5) The kernels are discharged, and when the kernel volume inside the kernel tank (19) decreases, the two push pipes (36) are moved closer by the coil spring (37) to squeeze the tank bottom (31). The angle of inclination of the tank bottom (31) is formed larger than the angle of repose of the grain (about 45 degrees or more), and the grain tank (19)
Take out all the grains inside the paddy bag (3
Slide down to 5).

Also, the bottom (31) of the grain tank (19)
Is shrunk by elastic force to form a bottom (31) inclination angle larger than the angle of repose of the kernel, and the bottom (3) of the kernel tank (19) is resistant to the shrinking force by the input kernel weight.
1) is swelled and the grain tank (1
The inclination of the bottom (31) of the grain tank (19) becomes smaller than the grain angle of repose to increase the capacity of the grain tank (19), and when the amount of grain inside the grain tank (19) decreases, the grain tank (19) becomes smaller. The inclination of the bottom portion (31) becomes larger than the angle of repose of the grain, and the grain is slid down by its own weight in the direction of the take-out port, thereby increasing the capacity of the grain tank (19) and improving the harvesting workability.

Further, as shown in FIGS. 10, 11 and 12, the push pipe (36) and the coil spring (3) shown in FIG.
In place of 7), an elastic rubber ring (38) is provided on the cloth bottom (31) of the grain tank (19), and the grain tank (1) is provided.
9) When the amount of grains inside is large, the tank bottom (31) is expanded by expanding the rubber string (38), and the tank bottom (31) is reduced by reducing the rubber string (38) by reducing the amount of grain. ), And similarly to FIG. 9 described above,
The bottom part (31) of the grain tank (19) is contracted by elastic force to form a bottom part (31) inclination angle larger than the angle of repose of the grain, and the grain against the contraction force by the weight of the input grain. The bottom (31) of the tank (19) is swelled, and the introduction of the grain causes the bottom of the grain tank (19) to have a smaller inclination than the grain angle of repose, thereby increasing the capacity of the grain tank (19) and increasing the grain size. When the amount of the grain inside the grain tank (19) decreases, the inclination of the bottom of the grain tank (19) becomes larger than the grain repose angle.

[0012]

As is apparent from the above embodiments, the present invention provides a grain tank (19) on a paddy receiving stand (21) behind a driver's seat (16). The grain tank (19) is formed so as to be freely foldable by a cloth bag in a combine for collecting grains in a paddy bag (35) installed in an outlet (32) below the grain tank (19). Even when the grain tank (19) is raised to increase the capacity by increasing the upper surface side, when no grain is contained, the bulk of the grain tank (19) is reduced to increase the volume from the driver's seat (16). The rear view of the worker can be widened, the rear view of the worker can be easily secured, and the weight and cost can be easily reduced as compared with those made of synthetic resin or iron plate. Grain tank (1)
The capacity of 9) can be easily expanded, and the operability and the harvest workability can be easily improved.

Further, the bottom of the grain tank (19) is contracted by elastic force to form a bottom inclined angle larger than the angle of repose of the grain, and the grain tank ( 19) The bottom is swelled, and the introduction of the grain makes the bottom of the grain tank (19) smaller than the grain repose angle, so that the capacity of the grain tank (19) can be increased and the grain can be increased. When the amount of grains in the tank (19) is reduced, the inclination of the bottom of the grain tank (19) becomes larger than the grain angle of repose, and the grains can slide down by their own weight in the direction of the outlet, and the grain tank ( 19) It is possible to easily achieve the expansion of the capacity and the improvement of the harvest workability.
