Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral row fertilizer application device for rice transplanters.

[0002]

2. Description of the Related Art Conventionally, side-row fertilizer applicators of rice transplanters have been equipped with a fertilizer feeding section connected to the bottom of a plurality of fertilizer hoppers on the peripheral wall of a cylindrical blower pipe having a blower on one end side. A plurality of flexible pipes communicating with the row fertilizer nozzle are connected to each other, and the fertilizer fed from the fertilizer feeding section by the air blow from the blower is fed to the side row fertilizer nozzle through the flexible pipe and planted from the nozzle. It is configured to apply fertilizer to the rice field close to the appendix.

[0003]

However, since the fertilizer hopper is located directly above the planting strip, the blower projects laterally of the rice transplanter, and the lateral strip fertilizer application is no longer symmetrical. There is a problem that the left and right weight balance becomes unbalanced and the rice transplanter is inclined to the left and right.

Further, since the blower projects laterally from the rice transplanter, it is difficult to operate, and there is a problem that a wide space is required to store the rice transplanter.

[0005]

In the present invention, a plurality of side-row fertilizer nozzles, which apply fertilizers in the vicinity of a plurality of seedlings, are connected to each other through a plurality of fertilizer feeding cases and blower pipes. It is characterized in that a plurality of fertilizer hoppers are offset from the position above each planting row by 1/2 of the interval between each planting row so that each fertilizer hopper is located above the middle of each planting row. It intends to provide a side-row fertilizer applicator for a rice transplanter.

Another feature is that a blower is arranged at the end of the blower pipe opposite to the offset.

A steering handlebar 14 is provided at the rear of the hood 9 in front of the driver's seat 13.

Reference numeral 15 in the drawing is a planting section for planting 5 rows, and the forward tilting type seedling table 16 is provided with a lower rail 18 and a guide rail.
The rotary case 21 is supported by the planting case 20 so as to be slidable left and right, and is rotated at a constant speed in one direction. The rotary case 21 is supported by the planting case 20 at a symmetrical position about the rotation axis of the case 21. , A pair of claw cases 22 are arranged,
The planting claws 17, 17 are attached to the tip of the claw case 22.

Further, the planting portion 15 is connected to the rear side of the traveling machine body 1 via a three-point link mechanism 27, and the raising and lowering cylinder 28 is expanded and contracted to raise and lower the planting portion 15.

With this configuration, the traveling machine body 1 has a planting portion.
While pulling and driving 15, the planting claws 17, 17 slide the seedlings from the seedling platform 16 that slides back and forth to the left and right so that the planting claws 17 pick up one seedling for continuous planting. .

In the figure, 29 is a center marker, 33 is a brake pedal, 34 is a center float, and 35 is a side float.

A fertilizer application support frame 40 having a front view portal shape is erected on the upper surface of the rear end of the vehicle body frame 3, and a lateral strip fertilizer application B is disposed above the fertilizer application support frame 40.

As shown in FIGS. 2 and 3, the side strip fertilizer applicator B is connected to a feeding case 47 for feeding a fixed amount of fertilizer to a lower portion of a fertilizer hopper 46 arranged at an upper portion, and the feeding case 47 is provided.
The upper end of the flexible pipe 49 is communicatively connected to the lower part of the flexible pipe 49, and the lateral strip fertilizing nozzle 48 for fertilizing is also communicated to the lower end of the flexible pipe 49 so that the lateral strip fertilizing mechanism b is connected. It is composed of 5 sets of side-row fertilizer application mechanism b, which are connected at the feeding case 47 through the cylindrical blower pipe 50,
A blower 51 for transferring fertilizer from the feeding case 47 to the side-row fertilizer nozzle 48 is continuously connected to the right end of the blower pipe 50, and the left-hand end is closed to form a side-row fertilizer application device 5 for planting five rows. Are configured. In the figure, 48a is a grooving device.

With such a structure, the fertilizer stored in the fertilizer hopper 46 is fed out by the feeding case 47 by a fixed amount, and by the air fed from the blower 51 through the blower pipe 50,
By ejecting a fixed amount of fertilizer fed from the side-row fertilizer application nozzle 48 through the flexible pipe 49, a certain amount of fertilizer can be applied to the rice field in the vicinity of the seedling planting row d.

In the side-row fertilizer applicator B, according to the present invention, as shown in FIGS. 2 and 3, the fertilizer hoppers 46 ... And the feeding cases 47 ... However, by arranging the planting strip d by offset e on the left side by 1/2 of the interval, the planting strip d to be fertilized and the planting strip d adjacent to the left side can be positioned above the center, and The blower 51 is arranged at the right end of the blower pipe 50, that is, at the end opposite to the offset e.

2 and 3, 52 is a blower drive motor,
53 is the lid of the fertilizer hopper.

Further, as shown in FIG. 1, the rear wheel fender 54 connected to the step 11 is extended to the vicinity of the rear end of the rear wheel 8 and is flexible along the upper surface of the rear wheel fender 54 on the left and right sides. By arranging the pipe 49 to prevent the flexible pipe 49 from being caught in the rear wheel 8, the fixing structure of the flexible pipe 49 is simplified.

[0019]

According to the present invention, the constitution of claim 1, that is, the plurality of side-row fertilizer nozzles that apply fertilizer in proximity to the plurality of seedling planting rows, the plurality of fertilizer feeding cases, and the blower pipes. A plurality of fertilizer hoppers that are respectively communicated with each other via the above are arranged offset from the upper position of each planting article to the upper position in the middle of each planting article. Further, at least one of the flexible pipes can be arranged along the side surface of the planting case to simplify the fixing structure of the flexible pipe.

Further, by the structure of claim 2, that is, by disposing the blower on the side opposite to the offset of the blower pipe, the weight balance between the left and right sides of the side-row fertilizer application is improved, and at the same time, the rice planter main body The blower does not extend to the side, the rice transplanter can be operated easily, and the storage space is small.

Although the rice transplanter for planting 5 rows has been described in the above embodiment, another number of rows, for example, 6 rows is used.
The present invention can be applied to a rice transplanter for row planting.
