Regarding powder and granular material tanks.

[Conventional technology]

This type of powder and granular material supply work vehicle was developed in the 1980s, for example.
- As shown in Publication No. 121708, two types of powder and granules are stored separately in two spaces separated by a partition plate, and the two types of powder and granules can be supplied to the field with one delivery roll. It is constructed. Conventionally, the powder tank was partitioned into only the front and rear of the machine by a partition plate.

[Problem that the invention attempts to solve]

Therefore, since the spaces inside the two tanks separated by the partition plate are lined up in the front and back direction of the aircraft,
Although the tank is made of a transparent material so that the interior can be easily seen, depending on the height relationship between the control section and the powder, visibility from the control section into the space inside the tank located on the rear side may be poor or impossible. This made it difficult or impossible to judge the amount of powder remaining on the rear side from the control section.

An object of the present invention is to enable the remaining amounts of two types of powder and granular materials to be easily determined from the control section, regardless of the positional relationship between the tank and the control section.

[Means for solving problems]

The characteristic structure of the present invention is that the partition plate in the powder tank of the powder supply work vehicle mentioned above is formed to be bent in plan view, and the vertical part facing the control part of the powder tank is One end of the partition plate is brought into contact with the vertical wall part so that a part of the wall part forms the first space and the remaining part forms the second space, and the operation and effect are as follows. It is as follows.

[Effect]

That is, because the partition plate has the bent shape,
The inside of the tank is partitioned so that a part of each of the two tank spaces to be created faces the vertical wall on the control side of the tank, and the upper surface level of both of the powder and granular materials stored in the two tank spaces is divided. can be seen through the vertical wall.

[Effect of idea]

Therefore, by being able to see the upper surface level of the powder and granules in either of the two internal spaces of the tank through the front vertical wall, it is possible to easily check the remaining amount of either of the two types of powder or granules from the control unit. It has become possible to easily and accurately judge the timing for replenishing powder and granules, and to work while easily avoiding supply errors caused by running out of powder and granules.
