BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural powder-dispersing device for spraying agricultural powders such as crop seeds and fertilizers to a field.

[0002]

2. Description of the Related Art There is a fertilizer application device for feeding fertilizer to a field as one of the above-mentioned agricultural powder and granular material application devices, and an example of this fertilizer application device is disclosed in Japanese Utility Model Laid-Open No. 2-70618. .. In this fertilizer applicator, a fertilizer storage tank (6 in FIG. 2 of the publication), a feeding portion (7 in FIG. 2 of the publication) connected to the lower portion of the tank, and a lower portion of the feeding portion. And a funnel portion (10 in FIG. 2 of the publication), and a delivery roll (7a in FIG. 2 of the publication) having a recess on the outer surface is rotationally driven in the delivery portion to deliver the delivery roll from the lower part of the tank. The fertilizer is taken in the concave part of the container and discharged to the funnel part below. Further, a brush-like scraping member is provided which holds the excess fertilizer in the concave portion and leaves it on the tank side as the feeding roll rotates. A grooving device (corresponding to the feeding mechanism) for digging a groove in the field is provided (corresponding to the feeding mechanism), and the fertilizer from the feeding roll is a guide member for the funnel portion (see FIG. 10a) (corresponding to the first posture) to the first outlet (B in FIG. 2 of the above publication).
It is configured so as to be sent to the groover through 1).

[0003]

In the above-mentioned structure, the funnel portion is provided with the second outlet (B2 in FIG. 2 of the above publication) for discharging fertilizer. Therefore, when the fertilizer remaining in the tank after the fertilizing work is to be removed, the fertilizer in FIG.
The guide member 10a is switched to the posture indicated by the chain double-dashed line (corresponding to the second posture), and the brush-shaped scraping member in contact with the feeding roll is pulled out. With this configuration, the fertilizer in the tank passes between the outer surface of the feeding roll and the scraping member and is discharged from the second outlet by the guide member. However, in the above-described structure, when the fertilizer in the tank is extracted, there are two operations, that is, the operation of switching the guide member and the operation of extracting the scraping member, and there is room for improvement in terms of operability. It is an object of the present invention to configure the above-mentioned agricultural powder and granular material spraying device so that the agricultural powder and granular material remaining in the tank can be easily extracted.

[0004]

A feature of the present invention is that the above-mentioned agricultural powder or granular material spraying device is configured as follows. That is, the damming posture in which the scraping member is brought into contact with the outer surface of the payout roll, and the agricultural powdery substance in the tank that is separated from the outer surface of the payout roll are discharged to the funnel portion from between the outer surface of the payout roll and the scraping member. It is configured to be freely switchable to the discharge posture, and is interlocked to switch the scraping member to the discharge posture in conjunction with the switching operation of the guide member to the second posture side (the guide side to the second outlet for discharge). The mechanism is erected and connected across the guide member and the scraping member.

[0005]

With the above-mentioned structure, as shown in FIG. 1, for example, when the scraping member 17 is in the damming position in contact with the outer surface of the feeding roll 12 and the guiding member 18 is in the first position shown by the solid line, When 18 is switched to the second position indicated by the chain double-dashed line, the interlocking mechanism 24 automatically switches the scraping member 17 to the discharge position separated from the feeding roll 12 to the right in the drawing. This allows the tank 1
Agricultural powder particles remaining in 3 escape downward from the space between the outer surface of the feeding roll 12 and the scraping member 17,
It is discharged from the second outlet 8b by the guide member 18 in the second posture.

[0006]

As described above, in discharging the agricultural powder or granules remaining in the tank, conventionally, two operations, that is, the operation of the scraping member and the operation of the guide member were performed. In the present invention, the operation of the scraping member can be performed at the same time by operating the guide member, so that the agricultural powder or granular material remaining in the tank can be discharged by one operation. As a result, the operability of the discharge work of the agricultural powder is improved.
