Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a riding-type fertilizing rice transplanter that simultaneously performs fertilizer application and transplanting of seedlings, and is intended to improve weight balance.

(Prior Art) A riding-type fertilizing rice transplanter currently on the market is provided with a fertilizing device after the seedling platform 13. Also, Utsukai Showa 58
- As shown in Publication No. 59410, seedling stand 13
A system equipped with a fertilization device has been proposed before, but it has not yet been put into practical use.

(Problems to be Solved by the Invention) In the former case, where the fertilization device is located behind the seedling stand 13,
Since the center of gravity is located at the rear, a large balance weight is attached to the front end of the vehicle body 1 to compensate for this. This significantly increases the overall weight, making it difficult to operate in soft paddy fields. Furthermore, if you dare to operate this machine, it would be necessary to install double wheels, making the machine heavier and more expensive.

In order to solve this problem, some systems have appeared in which a fertilizer application device is installed in front of the seedling platform 13 (Utility Model Application Publication No. 58-59410, etc.), but in these known devices, the fertilizer application device is installed in front of the seedling platform 13. Since the power was transmitted to the feeding shaft 40, the lower end of the seedling stand 13 became high, making it undesirable to plant seedlings, and it also became expensive, so it is still only a proposal and has not been put into practical use. is not provided.

(Means for Solving the Problems) In order to solve these problems, the present invention provides a planting part case 1 connected to the rear of the vehicle body so as to move up and down.
0, a seedling platform 13 that tilts forward at the top and reciprocates from side to side on top of this planting part case 1o, and a loop curve that is located behind the seedling platform 13 and whose tip intersects with the bottom of the seedling platform 13. It is equipped with a seedling planting rod 21 that draws and moves, and a fertilizer tank 38 that is placed above the planting part case 10 and is provided between the vehicle body 1 and the seedling platform 13. The riding-type fertilizing rice transplanter is characterized in that it is connected to a rotary shaft 35 protruding from a planting part case 10 in front of the lower part of a platform 13 so as to be given rotational motion by a rod 44.

(Function) Therefore, the feeding shaft 40 under the fertilizer tank 38 is attached to the rod 44 on the rotating shaft 35 rotating in front of the lower part of the seedling stand 13.
are connected to provide rotational force.

Therefore, as the vehicle body 1 moves forward, the seedlings on the seedling platform 13 are transplanted by the seedling planting rod 21, and at the same time, the rotation of the feeding shaft 40 feeds out the fertilizer in the fertilizer tank 38, thereby performing fertilization.

(Effects) In this way, in this invention, the two operations of transplanting seedlings and spreading fertilizer are performed simultaneously in one operation of the vehicle body 1.
This greatly saves labor, and since the fertilizer tank 38 and feeding shaft 40 are located in front of the seedling platform 13, even if a fertilizer application device is added to an existing rice transplanter, the weight balance will not be disturbed. Furthermore, since the feeding shaft 4o is driven by the rod 44 from the rotating shaft 35 in front of the seedling platform 13, there is no need to raise the seedling platform 13, and even existing rice transplanters can easily operate the feed-out shaft 4o. It has the feature of being able to be modified at low cost.
