2. Description of the Related Art Conventionally, as a powder and granular material supply device of a rice transplanter, there are a fertilizer application device for supplying a granular fertilizer to a field and a drug application device for supplying a powdery and granular drug to a field. For example, Japanese Patent Application Laid-Open No. Hei 4-3
As disclosed in Japanese Patent No. 35805, the fertilizer applicator and the medicine applicator are separately configured and are interlocked and connected via a support frame or the like, so that the fertilizer application and the medicine applicator work can be performed simultaneously with the seedling planting operation by the seedling planter. Some were able to do both.

[0003]

However, according to the above-mentioned prior art, the fertilizer application device and the drug application device are separately configured, thereby requiring a support structure between the fertilizer application device and the drug application device, and requiring the support structure. Since the supporting structure becomes large, there is a problem that the manufacturing cost is increased. In addition, since the support structure becomes large, attachment and detachment of the drug application device to and from the fertilizer application device become cumbersome, and disadvantageous in performing maintenance such as cleaning of the feeding recess in the fertilizer application device and the drug application device, for example. I was

According to the first aspect of the present invention, since one type of granular material can be supplied by one granular material supply device, one of the two types of granular material is used as a fertilizer and the other as a chemical. By doing so, as in the case of separately configuring the fertilizer application device and the drug application device, the inconvenience of their configuration, the supporting structure or the transmission structure becoming large and the production cost increasing, and the inconvenience of having to attach and detach the device are solved. In addition, the weight and size of the entire device can be reduced. In addition, by reducing the weight and size of the entire apparatus, the influence on the weight balance of the entire rice transplanter can be reduced. In addition, since two types of feeding recesses are formed in the feeding roll, if the roll case is provided with an openable / closable opening, each opening recess can be easily exposed simply by opening the opening. This can be advantageous in performing maintenance such as cleaning of the respective feeding recesses. Furthermore, since a combined flow path is provided at the lower part of the two flow paths for merging and flowing down the respective powders and granules, it is compared with the case where each flow down path for individually flowing down the respective powders and granules is provided. Thus, the weight and size of the entire apparatus can be reduced, and the manufacturing cost can be reduced.
In addition, powdery and granular drugs tend to adhere and accumulate in the downflow path, but because they are made to flow down by being combined with the granular fertilizer that easily flows down in the merged downflow path, a special downflow that allows the drug to flow down alone The flow of the medicine can be promoted as compared with the case where the path is provided, and the maintenance work due to the clogging of the medicine in the merged flow path can be reduced.

[0009] According to the second aspect of the present invention, the flow-down path provided with the leakage net is made of fertilizer, thereby removing fine powders which are likely to adhere to and stay in the flow-down path from the fertilizer which is granular powder. Therefore, it is possible to prevent clogging of the downflow path by fertilizer. In addition, by removing the fine powder and granular material from the fertilizer, the fine powder and granular material (powder and granular fertilizer) that easily adhere to and stay in the granular fertilizer that easily flows down when the powdery drug is merged in the merging flow path And the drug) can be reduced, so that the flow of the drug in the merging flow path can be further promoted.

According to the third aspect of the present invention, when the medicine supply state is switched by operating the switching means, one of the granules is a medicine which needs to be embedded in the field mud such as an insect repellent or a disinfectant. Can be buried and supplied in the field mud by flowing down the combined flow path together with the fertilizer that is the other granular material, and it is necessary to disperse one granular material on the surface of the field mud like a herbicide etc. In the case of a drug having a certain characteristic, it can be sprayed and supplied to the surface of the field without being combined with the fertilizer which is the other granular material. That is, a medicine supply state suitable for the kind of medicine to be applied according to the condition of the field or the like can be made to appear.

[0011]

Therefore, according to the first aspect of the present invention, it is possible to reduce the weight and size of the entire apparatus, to reduce the manufacturing cost, and to apply fertilizer while having an advantageous structure in terms of maintenance. And a drug supply device for a rice transplanter capable of simultaneously and smoothly applying a drug.

According to the second aspect of the present invention, there is provided a powder and granular material supply apparatus for a rice transplanter which is more advantageous in terms of maintenance and which can flow down fertilizers and chemicals more smoothly and discharge it into field mud. It was possible to provide.

According to the third aspect of the present invention, it is possible to reduce the weight and size of the entire apparatus and to reduce the manufacturing cost, and it is advantageous in terms of maintenance, but adapted to the type of drug. Thus, it has become possible to provide a powder and granular material supply device for a rice transplanter capable of showing the improved drug supply state.
