Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer application apparatus for feeding granular fertilizer from a storage unit by a feeding mechanism in a predetermined amount and feeding the fertilizer to a groove making device through a supply path.

[0002]

2. Description of the Related Art Heretofore, as a fertilizer applying apparatus having the above-mentioned structure, there is one such as that disclosed in Japanese Utility Model Laid-Open No. 60-114612.

[0003]

Here, considering the situation when fertilizing granular fertilizer, in this type of fertilizer applicator, since the furrowing device is provided in a state of plunging into the field, fertilizer supply In the vicinity of the groover on the path, the water that has entered through the groover solidifies and grows fine powder separated from the fertilizer into a paste, which narrows the supply path or causes clogging. It can also occur. Therefore, it is conceivable to detachably install a container for collecting fine powder separated from the fertilizer, for example, in the vicinity of the fertilizer applicator such as when the seedling planting device of the rice transplanter is equipped with the fertilizer applicator. When the above devices are arranged, the space for attaching and detaching the container becomes small, so that a structure that can be easily attached and detached is desired.

The object of the present invention is to rationally arrange a container for collecting fine powder separated from fertilizer, to stably hold this container at the time of connection, to make it as easy as possible at the time of removal, and to use an adjacent device. The point is to obtain a structure that can be separated without being hindered by other types.

[0005]

A feature of the present invention is that in a fertilizer application apparatus constructed as described above, a container for collecting fine powder separated from fertilizer through a net is arranged below the supply path. In addition, a fitting portion that can be fitted to the member that forms the supply path by moving in the vertical direction and that is restricted from moving in the lateral direction is formed in this container, and a member that forms the supply path is formed. , A point that a connecting mechanism is provided between the container and the container to prevent the container from moving up and down.
The effects are as follows.

[0006]

When the above features are configured as shown in FIGS. 1 to 4, for example, by setting the connecting mechanism C in the connected state, the container 12 is prevented from moving up and down by the connecting mechanism C, and is laterally moved by the fitting portion 17. The movement is blocked, and the fitting of the container 12 is released by the downward movement by releasing the connection of the connecting mechanism C. In other words, the fitting portion 17 prevents the container 12 from moving laterally, and the connecting portion C has a structure that only prevents the container 12 from moving vertically.
Can be connected to prevent the movement of the fertilizer in the three-dimensional direction. Moreover, since the container 12 is arranged below the supply path A, the fertilizer passes above the net body 11, and the Even fine powder attached to fertilizer can be collected.

[0007]

Therefore, the container for collecting the fine powder separated from the fertilizer is arranged in a rational and highly recoverable state, and the container is kept in a stable state at the time of connection.
At the time of removal, without being disturbed by the adjacent devices,
The structure that can be separated is relatively simple.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling planting device and a seedling planting device having a planting mechanism for taking out the seedlings from the seedling placing table and planting them in a field scene. And a fertilizer application device configured to drop-feed granular fertilizer sent from a fertilizer tank through a supply path to a fertilizer groove formed in a field scene in a traveling machine body.

[0002]

2. Description of the Related Art As a fertilizer application apparatus constructed as described above, for example, as shown in Japanese Utility Model Laid-Open No. 60-114612, a granular fertilizer fed from a fertilizer tank is produced along with powdered fertilizer contained therein. Some are designed to be dropped and supplied toward the container. Here, in order to consider the situation when fertilizing granular fertilizer, in this type of fertilizer applicator, a groove making device is provided in a state of plunging into a field scene. Therefore, in the fertilizer applicator based on the above technique, the water that has entered from the grooving machine side hardens the powdered fertilizer, which is contained in large amounts in the granular fertilizer, and is hard to flow down into a paste form in the fertilizer supply path near the grooving machine. To grow and narrow the supply route,
In addition, it sometimes caused a clogging of fertilizer.

Therefore, as a technique for eliminating the drawbacks of the above structure, conventionally, a finely-powdered fertilizer is recovered by attaching a recovery container with a leak net to the bottom of the fertilizer tank (for example, , Jitsukai Sho 62-707
No. 23), or by providing a recovery container with a leak net in the middle of the flow path below the feeding device to recover the finely divided powdered fertilizer (for example, Japanese Utility Model Laid-Open No. 62-499).
09).

[0004]

However, according to the above prior art, the adhesion of the powdered fertilizer in the fertilizer supply route in the vicinity of the grooving device, as in the case of the above-mentioned structure which is not provided with the means for collecting the powdered fertilizer. Although this can be avoided while the recovery function is working well, if the recovery container is full of powdered fertilizer, the recovery and removal function of the powdered fertilizer will be impaired. Therefore, there is a new annoyance that one has to keep an eye on whether the container is full or not,
Further, the confirmation also requires the trouble of stopping the machine and then removing the container to confirm the degree of storage.

An object of the present invention is to use a powdered fertilizer recovery container to selectively collect and recover the powdered fertilizer contained in the granular fertilizer to narrow the supply route due to the adherence of the powdered fertilizer and to prevent the clogging of the fertilizer. In doing so, it is to make it possible to easily confirm the storage status of the powdered fertilizer in the collection container and to maintain the ease of confirmation for a long period of time.

[0006]

In order to achieve the above object, the first invention comprises a seedling stand and a planting mechanism for taking out the seedlings from the seedling stand and planting them in a field scene. Equipped with a seedling planting device and a fertilizer application device configured to drop and supply the granular fertilizer sent from the fertilizer tank through the supply path to the fertilizer application groove formed in the field scene with the grooving device In the rice transplanter with a fertilizer application, a feeding device for feeding the granular fertilizer in the fertilizer tank to the groover side by a predetermined amount is arranged above the planting mechanism, and the feeding device is provided with a granular material in the middle of feeding. Powder fertilizer sorting having a sorting net body that leaks the powder fertilizer contained in the fertilizer and guides the granular fertilizer to the groover side, and a collection container that receives and stores the powder fertilizer that has leaked from the sorting net body Recovery device Provided, the recovery container is made of a transparent resin molded product, and is disposed at a position visible from the rear of the machine body, and the feeding device is provided between the planting mechanism and the feeding device from the planting mechanism side. A mudguard plate was installed to prevent mud from splashing to the side.

According to the second invention, in the first invention,
In addition to the supply port for feeding the granular fertilizer from the fertilizer tank to the groover side in the feeding device, a discharge port capable of extracting the granular fertilizer from the fertilizer tank is provided, and the powder fertilizer sorting and collecting device and Each of the discharge ports,
The mudguard plate was disposed above the mudguard plate, and the mudguard plate was detachably attached to the fixed portion of the seedling planting device.

[0008]

According to the first aspect of the present invention, the granular fertilizer containing the powdered fertilizer fed out from the fertilizer tank by the feeding device is leak-separated when passing over the sorting net, and the powdered fertilizer contained in the granular fertilizer is removed. As it leaks from the sorting net and is stored in the recovery container, only granular fertilizer is guided to the groover side and dropped and supplied, so the water that has entered through the groover will generate powdered fertilizer. By narrowing the fertilizer supply route in the vicinity of the grooving device and solidifying the fertilizer by solidifying and growing it in the form of paste, granular fertilizer can be smoothly dropped and supplied toward the grooving device. In addition, the recovery container is made of a transparent resin molded product, and it is placed above the planting mechanism so that it can be seen from the rear of the machine. It is possible to easily confirm the powder fertilizer recovery status of the recovery container from the ridge, and it becomes possible to accurately determine the time when the powder fertilizer is recovered from the recovery container. Moreover, since a mudguard plate is provided between the planting mechanism and the feeding device to prevent the mud from scattering from the planting mechanism side to the feeding device side, the mud that is scattered with the seedling planting operation of the planting mechanism is installed. Since it adheres to the collection container provided on the feeding device and the auxiliary worker cannot easily check the powder fertilizer collection status of the collection container from the ridge, it is possible to see through the collection container even during long-term work. Can be maintained in a state.

According to the second aspect of the present invention, since the discharge port for discharging the granular fertilizer from the fertilizer tank is separately provided,
It becomes easy to extract and collect granular fertilizer from the fertilizer tank. In addition, since the powdery fertilizer sorting / collecting device and the discharge port are arranged above the mudguard plate, the mud scattered from the planting mechanism side does not adhere to the powdery fertilizer sorting / collecting device and the discharge port. There is no inconvenience that mud adheres to or mixes with the granular fertilizer when the granular fertilizer in the fertilizer tank is extracted and collected from the outlet. Moreover, since the mudguard plate is detachably attached to the fixed part of the seedling planting device, it is necessary to remove the mudguard plate when removing the granular fertilizer from the fertilizer tank from the discharge port and collecting it. A container or a collection bag for collecting the granular fertilizer extracted from the outlet can be easily located near the discharge port.

[0010]

As described above, according to the first aspect of the present invention, the powdered fertilizer contained in the granular fertilizer can be selected and collected to suppress the narrowing of the supply route due to the adhesion of the powdered fertilizer and the clogging of the fertilizer. Therefore, it has become possible to improve the efficiency of fertilization work. In addition, since it is possible to accurately determine the time when the powdered fertilizer is collected from the collection container, it is possible to efficiently collect the powdered fertilizer from the collection container. Moreover, since the mud from the planting mechanism side does not adhere to the collection container, it is advantageous in terms of maintenance, and it has become possible to efficiently collect the fertilizer from the collection container for a long period of time.

According to the second aspect of the present invention, the work of extracting the granular fertilizer from the fertilizer tank can be easily and efficiently performed while preventing mud from adhering to or mixing with the granular fertilizer.
