Abstract

PURPOSE:To enable smooth flow of fertilizer by placing a fertilizing apparatus between a mobile machine body and a seedling table in a specific state. CONSTITUTION:An inclination angle of a seedling table 5 is decreased and a fertilizer delivery mechanism 11 is placed at a low level in a wide space formed between a transplantation transmission case 7 and a lifting link mechanism 2. The flow-down path of fertilizer to the fertilizing groove formed on a field by a furrowing tool 12 can be shortened and straightened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects a rear part of a traveling vehicle body with a seedling planting device through an elevating link mechanism, and
The present invention relates to a riding-type rice transplanter with a fertilizer application, which is equipped with a fertilizer application device.

[0002]

2. Description of the Related Art A riding-type rice transplanter equipped with a fertilizer application apparatus has a fertilizer storage hopper of the fertilizer application apparatus and a fertilizer feeding mechanism of a fertilizer application apparatus for a seedling stand in a forward inclined posture, as disclosed in, for example, JP-A-3-10612. It is currently widely used in the form of being arranged at the rear.

[0003]

In the above configuration,
Since the fertilizer storage hopper and the fertilizer feeding mechanism, which are the main parts of the fertilizer application device, are installed behind the seedling stand, these become an obstacle when removing the seedlings remaining on the seedling stand after the planting work is completed. In addition, if it is necessary to replenish the fertilizer storage hopper with fertilizer during the planting work, there is the trouble of entering the field and going to the rear part of the vehicle body. Further, for example, as disclosed in Japanese Utility Model Laid-Open No. 58-152829, a fertilizer application device is installed between a traveling vehicle body and a seedling stand to remove seedlings remaining on the seedling stand. A form has been proposed in which the device can be easily supplied without being disturbed, and the fertilizer can be supplied from the driver's seat of the traveling vehicle body.
A planting mission case, etc. is located in the lower part of the space between the traveling vehicle body and the seedling stand, and the fertilizer feeding mechanism cannot be set low. Is likely to become long or bent, the time difference from the fertilizer feeding mechanism to the fertilizer ditch becomes large, and it is expected that fertilizer clogging in the hose will occur. Not in practical use. The present invention has been made by paying attention to such an actual situation, and by improving the configuration of the seedling planting device, the present invention is intended to solve the above problems and problems of the proposed structure. Is.

[0004]

In order to achieve the above object, in the present invention, the inclination angle of the seedling stand in the forward tilted posture provided in the seedling planting device is set to be gentle, so that A large interval is set between the planting mission case arranged in the front and the elevating link mechanism, and the fertilizer application device is arranged between the traveling vehicle body and the seedling stand so that the fertilizer feeding mechanism is located within this interval. It has a configuration.

[0005]

According to the structure of the present invention, the fertilizer feeding mechanism is arranged at a low position within a large space formed between the planting mission case arranged in front of the seedling stand and the elevating link mechanism. As a result, the flow path to the fertilizer ditch formed in the field becomes short and linear. Further, the fertilizer supply to the fertilizer storage hopper provided between the traveling vehicle body and the seedling planting device can be performed from the driver's seat of the traveling vehicle body. In addition, since the seedling stand has a lower tilt angle and the lower part of the seedling stand is positioned rearward of the machine than the conventional device, if the position of the upper end of the seedling stand is the same as the conventional one, the whole length of the seedling stand becomes longer, The amount of seedlings placed will increase accordingly.

[0006]

As described above, according to the present invention,
A fertilizer applicator can be installed between the vehicle body and the seedling stand, making it easy to remove the remaining seedlings and replenish the fertilizer from the driver's seat. Moreover, by changing the form of the seedling planting device for that purpose, the amount of seedlings placed on the seedling stand was increased, enabling efficient planting work with a long seedling supply interval.

EXAMPLE A riding type rice transplanter with a fertilizer application apparatus according to the present invention is
As shown in FIG. 1, a seedling planting device 3 is connected to a rear portion of a riding type traveling car body 1 via a hydraulically driven lifting link mechanism 2, and a fertilizer application device is provided between the traveling car body 1 and the seedling planting device 3. The seedling planting device 3 is configured to be equipped with 4 and the seedling planting device 3 cuts out seedlings from a lower end of the seedling stand 5 in a forward tilted posture that is horizontally reciprocally moved laterally and planted in a field. A rotary type planting mechanism 6, a planting mission case 7 having a lateral feed mechanism for the seedling stand 5, a planting case 8 having the planting mechanism 6, a leveling float 9, and the like, and the fertilizer applicator 4 Is
The fertilizer storage hopper 10, the feeding roller type fertilizer feeding mechanism 11 provided at the lower end thereof, the grooving mechanism 12 that forms a fertilizing groove in the field, and the fertilizer fed from the fertilizer feeding mechanism 11 to the grooving mechanism 12. Hose 1 to guide downflow
3 and the like. Further, the seedling placing table 5 in the front tilted posture is set such that the tilt angle thereof is looser than the conventional one so that the upper end position is equivalent to the conventional one and the lower end position is located rearward from the conventional one. The distance between the rear end 2 and the planting mission case 7 arranged on the lower front side of the seedling stand 5 is configured to be larger than the conventional one. The fertilizer storage hopper 10 and the fertilizer feeding mechanism 11 are arranged between the elevating link mechanism 2 and the planting mission case 7, and the grooving mechanism 12 is arranged immediately below. This groove making mechanism 12
The rotating disk 15 having the fertilizer-filling recesses 14 formed at predetermined intervals on the circumference is thrust into the field to continuously form a fertilizer application groove having an appropriate depth, and the recesses 15 are filled at the upper part of the disk. It is configured to bring fertilizer to the bottom of the disc and supply it to the fertilizer ditch. The fertilizer storage hopper 1
0 is the capacity that can store a small amount of fertilizer,
The auxiliary hopper 17 installed at the rear of the driver's seat 16 of the traveling vehicle body 1 is communicatively connected via a hose 18. As shown in FIG. 2, the auxiliary hopper 17 has a lower end 1 through
9 can be opened and closed with a shutter 20,
It is possible to slide laterally from the set position at the rear of the driver's seat 16 via the guide rail 21 installed on the traveling vehicle body 1 and to remove it from the guide rail 21, and replenish the fertilizer from the edge with the auxiliary hopper 17. Is configured to be able to.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the structures of the accompanying drawings by the entry.
