Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a riding rice transplanter equipped with a spraying device for spraying chemicals such as herbicides or fertilizers around seedlings planted in a field. It is. [Prior art and its problems] When a rice transplanter is equipped with a mechanism for dispersing chemicals such as fertilizers, the mechanism for dispersing chemicals such as fertilizer is used to spray seedlings in the rice transplanter as described in, for example, Japanese Utility Model Publication No. 54-84223. It was common to attach it to the back side of the platform, but this is attached to a seedling planting device that is connected to the rear of a traveling machine that runs on wheels so that it can rise and fall up and down via a link mechanism. When applied to a so-called rear-planting riding type rice transplanter that is equipped with a seedling stand that is inclined so that it approaches Since the length of the link mechanism that connects the seedling transplanter to the machine body so that it can be raised and lowered up and down must be increased, the overall length of the riding rice transplanter is longer (as well as the stiffness of the link mechanism increases Furthermore, since the chemical dispersion mechanism is located between the traveling machine and the seedling planting device, replenishment of the chemical to the chemical dispersing mechanism is accomplished by lifting the chemical onto the traveling machine and removing it from the traveling machine. Since the chemical must be supplied from above and the chemical cannot be supplied directly to the chemical dispersion mechanism from the ridges in the field, replenishing the chemical requires time and effort.The present invention solves this problem. Means for Solving Problem C] For this reason, the present invention provides a seedling planting device that is connected to the rear part of a traveling body that runs on wheels so as to be able to rise and fall through a link mechanism. , a riding type rice transplanter comprising a seedling platform whose upper part is inclined so as to approach the traveling machine body; In addition to providing a chemical dispersion mechanism for dispersing the chemical,
The structure includes a power source for driving the chemical spraying mechanism separately from the seedling planting device. [Operations and Effects of the Invention] When a chemical dispersion mechanism is provided in a so-called rear-planting riding-type rice transplanter, the chemical dispersion mechanism is disposed on the rear side of the seedling stand in the seedling transplanting device, so that it can be connected to the traveling machine body. By running the rice transplanter in a bank, the distance between the rice transplanter and the rice transplanter becomes narrower, and the length of the link mechanism that connects the seedling transplanter to the traveling machine so that it can move up and down can be shortened. This allows the chemical dispersion mechanism to be brought closer to the ridges in the rice field. Therefore, according to the present invention, the following effects are achieved. ■When installing a chemical dispersion mechanism on a so-called rear-planting rice transplanter, the chemical dispersion mechanism and its power source are placed behind the forward-tilting seedling stand of the seedling transplanter, making it possible to While it is possible to avoid an increase in the overall length and weight of the machine, it is also possible to replenish the medicine to the medicine dispersion mechanism directly from the ridge in the rice field very easily. ■By arranging the chemical dispersing mechanism behind the forward-tilting seedling stand in the seedling planting device, this chemical dispersing mechanism
Since it can be viewed from above the traveling aircraft, the remaining amount of medicine in the medicine dispersion mechanism and the operating state of the medicine dispersion mechanism can always be visually confirmed. □ By configuring the power source for driving the chemical dispersing mechanism separately from the seedling planting device, the drive mechanism of the chemical dispersing mechanism □ drives the chemical dispersing mechanism by power transmission from the seedling planting device. As a result, the rice transplanter can be made smaller and lighter, and can be provided at a lower cost.
