Description

[Detailed description of the invention] [Field of industrial application] The invention is a device that is attached to a rice transplanter and applies fertilizer to the side of the planted seedlings at the same time as planting.
The present invention relates to a fertilizer application device that is provided with a supply tool that forms a groove in a field as it progresses and supplies fertilizer into the formed groove.

[Conventional technology]

In this type of fertilization device, it is necessary to backfill the forming groove after fertilizer is supplied. Therefore, in the past, means for providing an arm at the rear of the supplying tool by pressing the field area on the side of the groove to backfill the forming groove, and a means for installing an arm at the rear of the supplying tool to backfill the forming groove and the field area on both sides thereof. A method of providing a plate that presses the surface portion and backfills the formed groove has been adopted.

[Problem that the invention attempts to solve]

However, when using the former conventional method, when the field surface is soft, it is possible to backfill the forming groove, but when the field surface is hard, the backfilling arm only collapses the field mud on the side of the groove. There is a drawback that the formed groove cannot be reliably backfilled. In addition, when using the latter conventional method, even if the field is hard, the formed groove can be reliably filled by the cooperation of the action of breaking up the mud by the backfill plate and the pushing action of the broken mud from above. On the other hand, if the field is soft, the backfill plate may push the mud too hard to the side, resulting in poor planting, such as overturning of already planted seedlings.

The purpose of the present invention is to eliminate such conventional drawbacks.

[Means for solving problems]

The characteristic structure of the fertilization device according to the present invention, which was taken to achieve the above object, is that it is located at the rear of the feeding tool on both sides of the forming groove, and presses the field area on the side of the groove to form the fertilizer. A pair of left and right backfilling arms arranged in a V-shape in rear view so as to backfill the groove, and a pair of left and right backfilling arms positioned above the forming groove and pressing the forming groove and the field surface portions on both sides thereof. A backfilling plate for filling the forming groove is provided, and the backfilling plate is configured to be freely switchable to a non-operating state separated upwardly from the forming groove, and further, the backfilling plate and the backfilling arm are connected to each other. is disposed in such a way that the backfilling plate is positioned between both backfilling arms in a plan view, and its functions and effects are as follows.

[Effect]

When the field is hard, by switching the backfilling plate to the active state, the formed groove can be reliably backfilled by the cooperative action of the backfilling arm and the backfilling plate.

Moreover, since the backfilling board and the backfilling arm are arranged such that the backfilling board is located between the pair of left and right backfilling arms in a plan view, the mud pressed down by the backfilling board is The backfill arm prevents the backfill from escaping to the side, making it possible to backfill the groove more reliably.

When the field is soft, the backfill plate is switched to a non-active state and the trench is backfilled only with the backfilling arm, thereby making it possible to backfill the trench without causing excessive mud pushing. I can do it.

[Effect of idea]

As a result, regardless of the hardness or softness of the field, and
It is possible to reliably backfill the formed groove and ensure the intended fertilization without causing planting defects such as falling of already planted seedlings, and it is also a type that can switch the backfilling form depending on the hardness and softness of the field. However, since the only thing to be changed is the backfill plate, it has become possible to provide a fertilization device that has a simple switching structure and operation, and can be easily implemented.
