Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain tank mounted on a harvester such as a combine or a harvester, and more particularly, to a grain tank for storing grains and making the stored grains visible from the outside. Related to the structure.

[0002]

2. Description of the Related Art The above-mentioned harvester is equipped with a grain tank for temporarily storing grains threshed in a threshing unit mounted on the machine body. The grains stored in the tank are then transferred to a transport vehicle and transported to a predetermined location. By the way, since the timing of transferring the grain to the transport vehicle is determined by the amount of the grain in the grain tank, conventionally, the grain tank is, for example, a side face of a resin grain tank (the side face is a driver's side). An opening is provided on the front or back side of the device), and a flat transparent plate is attached to the opening, so that the amount of grains can be confirmed through the transparent plate. .

[0003]

However, in the structure in which the flat transparent plate is attached, the amount of grains in the grain tank can be checked only from the front of the flat transparent plate installation surface. The amount of grain was checked by a driver in front of the installation surface by looking into the flat transparent plate while operating the harvester.

[0004] In such a method, when the driver is distracted by the operation of the harvester, it is easy to create a situation in which the timing of transfer to the transport vehicle is missed. When the amount of the tank becomes full, the harvesting operation cannot be continued at that time, so that the operation cannot be performed smoothly and the efficiency of the operation is significantly reduced.

The present invention has been made to solve the above-mentioned problem, and has a structure in which the amount of grains in a grain tank can be easily confirmed not only from one direction in front of the installation surface but also from a plurality of directions. It is an object of the present invention to provide a grain tank for a harvester.

[0006]

In order to achieve this object, the present invention provides an airframe (1) supported by a traveling device (16).
2) In a harvester (10) equipped with a grain tank (22) for accommodating grains, an opening (28) provided in the grain tank (22) is formed so as to project outward. Characterized in that it is provided with a transparent cover (30).

[Operation] With the above configuration, it is possible to easily confirm the amount of the grains in the grain tank (22) not only from one direction but also from a plurality of directions via the transparent lid (30). Becomes

Note that the reference numerals in parentheses are for comparison with the drawings, but do not limit the configuration of the present invention.
