Description

[Detailed description of the invention] The present invention relates to a rice transplanter, and more specifically, an auxiliary tank having a fertilizer delivery part is attached to a planting device that is attached to the rear of the traveling machine so that it can be raised and lowered, and
The present invention relates to a rice transplanter with a fertilization device, which has a main tank provided on the traveling body side for supplying powdered fertilizer to the auxiliary tank.

When installing a fertilizer application device in a rice transplanter, a fertilizer discharge port should be provided near the planting claw in order to supply powdered or granular fertilizer immediately near the planting position of the seedlings, and the feeding mechanism should be started and stopped. An auxiliary tank with a feeding part is provided on the planting equipment side in order to bring the discharge port and the feeding part close together so that the fertilizer flows out from the discharge port and stops with a small time difference, and a storage part for a large amount of fertilizer is installed. The main tank is installed on the side of the traveling aircraft in order to avoid deterioration of the weight balance of the entire aircraft due to its weight when full and difficulty in controlling the attitude of the planting equipment due to the main tank being installed on the side of the planting equipment at the rear of the aircraft. However, in a rice transplanter with a fertilizer applicator having such a configuration, there were problems with the arrangement of the main tank and the auxiliary tank, as well as the means of supplying fertilizer from the main tank to the auxiliary tank, and the earlier application, Utility Model Application No. 1987-
In No. 92757 (Utility Model Publication No. 58-194615), we proposed a rice transplanter with a fertilization device in which the main tank was installed around the seat and the main tank and auxiliary tank were connected by a pipe equipped with a forced fertilizer conveying means. However, this configuration requires power to supply fertilizer from the main tank to the auxiliary tank, which not only increases the load on the engine, but also has the disadvantage of complicating the mechanism and requiring additional equipment.

The present invention aims to solve the above-mentioned drawbacks of such a rice transplanter with a fertilization device.

To achieve this purpose, the main tank is placed above the control section, the auxiliary tank is placed lower than the main tank, and the main tank and the auxiliary tank are connected by a flexible tube. This configuration is characterized by being connected in a straight manner.

Because of this configuration, the fertilizer in the main tank located at a high position is supplied to the auxiliary tank by gravity, and there is no need to use a special forced fertilizer conveyance means, and no fertilizer conveying power is required, making it extremely simple. With this configuration, fertilizer can now be supplied from the main tank to the auxiliary tank.

Next, examples will be shown.

As shown in FIG. 1, a pair of left and right driving front wheels 1
and a traveling body A equipped with a pair of left and right driving rear wheels 2.
A planting device B for planting five rows is connected to the rear of the device via one top link 3 and a pair of left and right lower links 4 so as to be movable up and down. A seedling platform 10, three soil leveling floats 11, and five planting claws 12 that are reciprocated and circulated between the seedling outlet of the seedling platform 10 and the mud surface.
, a driving unit 6 and a spare seedling stand 9 are provided on the front side of the traveling body A, and a main frame 15 that stores powder or granular fertilizer is installed at a high position above the control unit 14. A tank 7 is provided, and a support 5 is provided behind the seedling stand 10 of the planting device B.
Auxiliary tank 8 and float 11 attached to
A riding-type rice transplanter capable of applying fertilizer is constructed by disposing a fertilizing device C equipped with a furrower 13 and the like.

To explain the configuration of the fertilizer application device C in detail, a frame 15 is attached to the intermediate portions of the left and right preliminary seedling stands 9 and the driving unit 6 so as to be able to fall forward, and a shaft is attached to the intermediate portion of the upper side of the frame 15. body 1
A fixed rib portion 17 is attached to the main tank 7 via a rib portion 6 so as to be swingable back and forth.

As shown in FIG. 2, the rear lower fertilizer outlet 20 of the main tank 7 and the upper inlet 19 of the auxiliary tank 8 are connected by a relatively flexible pipe 18, and the inside of the main tank 7 is The fertilizer is supplied to the auxiliary tank 8 by flowing down due to its own weight, and the flexibility of the pipe 18 allows the planting device B to move relative to the traveling body A.

In addition, this pipe 18 and the fertilizer outlet 2 of the main tank 7
The connection point with 0 is configured to be able to be fitted and removed freely, and the fertilizer discharge port 20 is provided with a shutter 21, so that fertilizer is supplied to the main tank 7 with the frame 15 tilted forward. .

As shown in FIGS. 3 and 4, the auxiliary tank 8 has an upper surface 28 so that the fertilizer supplied from the inlet 19 spreads left and right and fills the entire auxiliary tank.
are inclined left and right, and the inlet 19 is provided at a high position in the center of the left and right sides. At the bottom of the auxiliary tank 8, feeding parts 22 that pair with the planting nails 12 are arranged side by side on the left and right. It consists of a rotary valve 25 that has a shutter 24 that can be opened and closed upwards and is placed at the bottom of the unit.
The lower opening is connected by a pipe 26 to a groove maker 13 formed on the lower surface of the float 11 so as to be arranged slightly to the side of the pair of planting claws 12, and is fed out from a rotary valve 25. The fertilizer is configured to fall into the furrower 13 through the pipe 26 and be supplied to the sides of the seedlings to be planted through the bottom opening.

Although not shown, the rotary valve 25
is mechanically interlocked with the drive mechanism of the planting claw 12 and driven synchronously, or driven by an electric motor.

In addition, when the tube 18 has an inner diameter of 30 mm, the tube 18 is approximately
It was confirmed that if the fertilizer is placed at an angle of inclination of 30° or more, the fertilizer can flow down naturally without stagnation.

In addition, in the fertilizer application device C having the above configuration, the fertilizer is filled in the main tank 7, the pipe 18, and the auxiliary tank 8 in a substantially connected manner.
The sum of the volumes of 8 and 8 is the maximum filling volume, and in practical terms, it is desirable to be able to fill at least 50 kg of fertilizer.
