Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter with a fertilizer application capable of performing fertilization on a field at the same time as planting seedlings. A spare seedling storage section is placed on the side of the front part of the machine, a fertilizer tank for storing granular fertilizer, a fertilizer application device for supplying the fertilizer to the field, and a fertilizer in the fertilizer tank for transfer to the fertilizer application device. The present invention relates to an apparatus provided with a fertilizer conveying means for supplying.

[0002]

2. Description of the Related Art In a conventional rice transplanter with a fertilizer application device of this type, a fertilizer tank having a fertilizer inlet is provided on the side of the operating unit of a self-propelled machine as disclosed in, for example, Japanese Patent Laid-Open No. 4-51804. It was equipped with a large amount of fertilizer so that the weight of the fertilizer could not be applied to the seedling planting device while working.

[0003]

However, according to the above-mentioned conventional technique, since the fertilizer inlet of the fertilizer tank is arranged on the side of the operating section, the fertilizer is replenished by stopping the machine at the edge of the ridge. Even if the aircraft is stopped forward with respect to the ridges and the front end side of the aircraft is brought close to the ridges, the fertilizer inlet will be located away from the ridges and out of reach. The fertilizer could not be supplied directly.

Even when the machine is stopped laterally with respect to the ridges, the fertilizer tank is installed close to the inside of the self-propelled machine, and the seedling stand of the seedling planting device projects to the lateral outer side of the self-propelled machine. Therefore, the distance between the fertilizer tank and the ridges became large, and the fertilizer could not be directly supplied from the ridges to the fertilizer tank.

Therefore, according to the conventional technique, an operator transfers fertilizer from the ridge to the self-propelled machine and puts it in the fertilizer tank, or an operator who is on the self-propelled machine does not care. They received fertilizer from the workers who were there and put it in the fertilizer tank.

In short, according to the conventional technique, it takes a lot of time to replenish the fertilizer tank with fertilizer.

An object of the present invention is to enable replenishment of fertilizer from the ridges to the fertilizer tank with good workability.

[0008]

The structure, operation and effect of the first invention according to the first aspect of the present invention are as follows.

[Structure] The fertilizer input port to the fertilizer tank is arranged on the lateral side of the preliminary seedling storage part, and the fertilizer application device is arranged behind the fertilizer tank.

[Operation] Since the fertilizer input port to the fertilizer tank is arranged on the lateral side of the preliminary seedling storage part and located at the front part of the self-propelled aircraft, the fertilizer is supplied to the fertilizer tank. At this time, by stopping the aircraft forward with respect to the ridges and bringing the front end side of the aircraft closer to the ridges, the fertilizer inlet can be brought closer to the ridges, and as a result, by adopting such a way of stopping the aircraft, It is possible for an operator to put fertilizer into the fertilizer inlet with one person's work while the operator is on the ridge.

Moreover, while the fertilizer inlet is arranged in the front part of the self-propelled aircraft so that the fertilizer can be supplied from the ridges in front of the aircraft to the fertilizer inlet, the lateral side part of the spare seedling storage part is not the front part. Since it is located at the front of the seedlings, it does not interfere with the supply of reserve seedlings from the front ridges to the reserve seedling storage area while adopting a configuration in which fertilizer supply from the fertilizer input port is performed from the front. Replenishment to the reserve seedling storage area can also be done directly from the ridges.

[Effect] As a result of the above, according to the first invention,
Replenishment of spare seedlings to the reserve seedling storage area While maintaining good workability, it became possible to supply fertilizer to the fertilizer tank with good workability by one person's work.

The structure, operation and effect of the second invention according to the second aspect of the present invention are as follows.

[Structure] In the structure of the first invention, the fertilizer tank is arranged on the lateral side of the preliminary seedling storage part, and the fertilizer input port is formed in the fertilizer tank.

[Operation] The fertilizer supply path from the fertilizer inlet to the fertilizer tank is unnecessary.

[Effect] As a result, the structure can be easily implemented, and the fertilizer can be reliably fed into the fertilizer tank without clogging in feeding the fertilizer from the fertilizer feed port to the fertilizer tank.

The third aspect of the present invention according to claim 3 has the following structure, operation, and effect.

[Structure] In the structure of the first invention or the second invention, a means for conveying fertilizer by a conveying pipe is provided as the fertilizer conveying means.

[Operation] Since the air transfer means or the screw transfer means can be adopted, the fixed amount transfer to the fertilizer application device can be stably performed without causing interruption of the fertilizer.

[Effect] As a result, fertilization can be stably and reliably performed.

The constitution, operation and effect of the fourth invention according to the fourth aspect of the present invention are as follows.

[Structure] In the structure of the third aspect of the invention, the carrier pipe is equipped with an outlet to the outside, and the fertilizer fed through the carrier pipe is fed to a fertilizer applicator in the fertilizer application state and outlet. The point is that a switching means is provided that can be switched between supplying and discharging.

[Operation] Since the switching means is provided to switch between the fertilization state in which fertilizer is supplied to the fertilizer application and the discharge state in which the fertilizer is discharged from the discharge port, the switching means switches to the fertilizer state. As a result, the fertilizer in the fertilizer tank can be discharged by switching to the discharge state while surely carrying the fertilizer to the desired fertilizer application device.

[Effect] As a result, by discharging the fertilizer in the fertilizer tank after the work is completed, it is possible to prevent the fertilizer from being moistened or altered in the fertilizer tank. This makes it possible to immediately apply fertilizer without the need for maintenance such as cleaning the inside of the fertilizer tank at the next use.

The structure, operation and effect of the fifth invention according to the fifth aspect of the present invention are as follows.

[Structure] In the structure of the third invention or the fourth invention, the fertilizer transfer means is provided with a transfer air flow supply device for supplying the transfer air into the transfer pipe.

[Operation] Since the fertilizer is pneumatically conveyed by using the conveying pipe as a guide by providing the conveying air flow supply device such as the air pump, the granular fertilizer is slid as compared with the screw conveying. It is not very easy to crush it with such things.

[Effect] As a result, the fertilizer can be conveyed to the fertilizer application in a granular form, and the fertilizer application can be stabilized.
