Description

[Detailed description of the invention] [Industrial application field] The present invention is a seedling planting device connected to a passenger vehicle body so as to be able to rise and fall, and is equipped with a chemical supply device that supplies chemicals such as fertilizer to the field as the seedlings are planted. The present invention relates to a riding rice transplanter with a drug supply device.

[Conventional technology]

The rice transplanter mentioned above can supply chemicals such as fertilizers and herbicides to the seedlings at the same time as planting the seedlings, and can perform the work efficiently. At first, Utsukai Showa 56-3788
As shown in the publication, a tank for storing chemicals was provided on the side of the seedling planting device.

[Problem that the invention attempts to solve]

In a riding rice transplanter that is equipped with a chemical storage tank only in the seedling planting device of the conventional structure described above, the weight of the entire seedling planting device increases due to a decrease in the amount of seedlings on the seedling platform and a decrease in the amount of chemicals in the storage tank. Changes become extremely large, and as a result, the front-to-back balance of the seedling planting device is likely to be thrown out of order.
This, combined with the fact that the weight of the seedling planting device, including the weight of the placed seedlings and the medicine, varies greatly, creates a drawback in that it is difficult to control the vertical movement of the seedling planting device. On the other hand, if the capacity of the tank is reduced in order to reduce changes in the weight of the seedling planting device, there is the inconvenience of having to frequently enter the field and replenish the chemicals each time.

Therefore, in order to eliminate these inconveniences, attempts have been made to install a storage tank on the passenger car body side. The length of the hose leading to the supply point becomes longer,
In addition, if the hose is extended close to the planting area away from the machine, the hose may hang down and become clogged, or it may be difficult to administer the chemical because it has to extend diagonally downward from the machine for a long time. It takes time to transport the medicine from the tank to the point where it is supplied, and there is a drawback that it is easy to supply too much or too little of the medicine to the seedlings, especially at the beginning and end of planting.

The present invention provides a riding-type rice transplanter with a chemical supply device that is free from the above-mentioned inconveniences by providing a tank on the seedling planting device side and a large tank communicating with the tank on the traveling vehicle body side. It is.

[Means for solving problems]

The technical means of the riding-type rice transplanter with a chemical supply device in the present invention is that the seedling planting device connected to the passenger vehicle body so as to be able to move up and down is equipped with a chemical supply device that supplies chemicals such as fertilizer to the field during seedling planting. In the riding-type rice transplanter with a drug supply device, the seedling planting device is provided with a tank for storing drugs to be supplied to the field by a drug delivery device, and a tank is provided on the passenger vehicle body side via a guide path leading to the storage tank. This is because a connected sub-tank is provided, and this configuration provides the following effects.

[Effect]

The seedling planting device is lowered relative to the vehicle body to plant the seedlings so as to reach a predetermined planting depth, and at the same time as the seedlings are planted, chemicals such as fertilizers in the storage tank are delivered to the field near the planting area using the medicine delivery device 28. supply
Then, as the amount of medicine in the storage tank decreases, the medicine in the sub-tank provided in the passenger vehicle body is replenished into the storage tank via the guide route. When the chemical in the sub-tank runs out and the chemical in the storage tank also decreases, the riding-type rice transplanter is moved to the edge of the ridge and the drug is supplied into the sub-tank from the edge of the ridge or by riding on the vehicle body.

[Effect of idea]

In this invention, in addition to the seedling planting device, a sub-tank that communicates with the storage tank provided in the seedling planting device is provided on the passenger vehicle body, so even if the storage tank capacity is reduced, the chemical can be kept for a long time. supply can be made. Therefore, while being able to supply chemicals to seedlings for a long period of time, it is possible to reduce the load on the seedling planting device and reduce changes in the weight of the entire seedling planting device due to work, thereby preventing imbalances in the front and back. It is possible to perform good seedling planting work with less seedlings.

Since the seedling planting device is equipped with a tank that stores the chemicals to be supplied to the field near the planting area using the medicine delivery device, the route from the storage tank to the medicine supply point is short and the distance from the storage tank to the medicine supply point is short. No clogging occurs during drug supply.
Furthermore, when the chemical in the tank is running low and needs to be replenished, by moving the riding rice transplanter to the edge of the ridge, the agent can be refilled from the edge of the ridge or by riding on the vehicle without having to enter the field each time. It has the advantage of being easy to carry out replenishment work.
