Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter, and more specifically, an auxiliary tank having a fertilizer dispensing part is attached to a planting device that is attached to the rear of the traveling machine so as to be able to rise and fall freely, and the auxiliary tank is filled with powder and granules. This invention relates to a rice transplanter with a fertilization device that has a main tank for supplying fertilizer on the side of the traveling machine.

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 lag, 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 auxiliary tank, as well as the means of supplying fertilizer from the main tank to the auxiliary tank.
In the specification of No. 92757 (Utility Model Application No. 58-194615),
We have proposed a rice transplanter with a fertilization device in which the main tank is installed around the seat, and the main tank and auxiliary tank are connected to each other by a pipe equipped with a forced fertilizer conveying means, but with this configuration, fertilizer is supplied from the main tank to the auxiliary tank. This not only increases the load on the engine, but also complicates the mechanism and requires additional equipment.

The purpose of the present invention is to solve the above-mentioned drawbacks of such a rice transplanter with a fertilization device, and also to provide a structure that allows rice transplanting to be carried out without any problems even in rainy weather.

To achieve this purpose, the main tank is placed above the control unit via a support frame, the main tank and the auxiliary tank are connected by a pipe for transporting fertilizer, and the support frame is connected to the The structure is characterized by a roof covering the main tank and the control section.

Because of this configuration, the fertilizer in the main tank can be supplied to the auxiliary tank by gravity without using power, and since a roof is provided to cover the main tank and the control section, even in rainy weather, rain will not flow into the main tank. The powdery fertilizer penetrates into the interior through the supply port, etc., and becomes moist.
Not only can the work be carried out smoothly without clogging the pipe and causing problems with supply, but it also protects the author from rain and sunlight and allows him to operate comfortably. Since the support frame supporting the main tank can be used as the support frame for the roof, it has an extremely simple structure and can be implemented at low cost, and is highly effective in practical use.

Next, examples will be shown.

As shown in FIG. 1, a pair of left and right driving front wheels 1
A traveling body A is provided with a pair of left and right driving rear wheels 2.
A planting device B for planting six 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 six 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 tank 7 for storing powder or granular fertilizer is provided above the control unit 14. an auxiliary tank 8 attached to a support 5 provided behind the seedling stand 10 of device B;
In addition, a fertilization device C equipped with a groove maker 13 installed on a float 11 is installed, a roof 29 is provided to cover the upper part of the main tank 7 and the control section 14, and a riding-type rice transplanter capable of fertilizing is installed. It is configured.

To describe the configuration of the fertilizer application device C in detail, a gate-shaped support frame 15 is attached to the intermediate portion between the left and right preliminary seedling stands 9 and the driving unit 6 so as to be able to fall forward, and the upper side of this frame 15 is The main tank 7 is attached as a shaft body 16 so as to be swingable back and forth and is suspended therefrom. Further, a branch frame 17 is fixed to the frame 15, and a rear branch frame 17 is fixed to the frame 15.
b, the roof 29 is attached so as to be rotatable around the horizontal axis 30, and is fastened to the front branch frame 17a, and when replenishing fertilizer to the main tank 7, the roof 29 is attached as shown by the imaginary line in FIG. By swinging the roof 29 upward, the upper surface of the main tank can be largely opened.

As shown in Figure 2, the fertilizer outlet 20 and the left and right auxiliary tanks 8 are provided at the rear lower part of the left and right main tanks 7.
The upper inlet 19 is a relatively flexible pipe 1.
8, and the fertilizer in the main tank 7 is supplied to the auxiliary tank 8 by flowing down due to its own weight. It is configured to allow relative movement with respect to the Further, the connection point between this pipe 18 and the fertilizer outlet 20 of the main tank 7 is configured to be able to be fitted and removed freely, and the fertilizer outlet 20 has a shutter 21.
The main tank 7 is provided with a structure in which fertilizer is supplied to the main tank 7 with the support frame 15 tilted backwards.

The upper surface 28 of the auxiliary tank 8 is inclined to the left and right so that the fertilizer supplied from the inlet 19 spreads left and right to fill the entire auxiliary tank, and the inlet 19 is located at a high point in the center of the left and right. It is located at the location. Further, the auxiliary tank 8 itself is made of a transparent plastic material having a remaining amount indicating line L. 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 which has a shutter 24 that can be opened and closed upwards and is arranged at the bottom of the section. The furrower 13 formed on the lower surface is connected to the furrower 13 through a pipe 26, and the fertilizer delivered from the rotary valve 25 falls into the furrower 13 through this pipe, and is used for seedlings to be planted from the bottom opening. It is configured to be fed laterally. Although not shown, the rotary valve 25 is mechanically interlocked and driven in synchronization with the drive mechanism of the planting claws 12.

In another embodiment, a pair of main tanks 7 and a pair of auxiliary tanks 8 may be provided on each side, as shown in FIG. Furthermore, although a flexible pipe was used as the pipe 18 connecting the main tank 7 and the auxiliary tank 8,
Furthermore, by adding a structure that slides and expands and contracts in the middle part, it is possible to use a harder tube.

The auxiliary tank 8 is made of a transparent material and has a scale so that the remaining amount of fertilizer can be seen from the outside at a glance.
