Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter with a fertilization device, which has a fertilization groove provided at the rear of a land leveling float.

- In general, in order to prevent straw waste from getting caught in the trencher when it is plunged into the rice field, a guide member such as a bar with an upward slope or a vertical plate is installed in front of the trencher. Efforts have been made to suppress foreign matter below the lower end of the furrower, but when planting paddy rice after wheat harvesting, a large layer of straw floats on the rice field, and even when the guide member is used, straw remains. Since the waste could not be fully embedded, the guide plate had the disadvantage that foreign matter such as straw waste could easily become entangled.

This drawback is that the entangled foreign substances become entangled with other foreign substances and grow, making the width of the fertilization groove wider than necessary and increasing the field surface sliding resistance at the seedling planting area. Ta.

The present invention was developed in view of the above-mentioned drawbacks, and by removing straw debris floating on the rice field as much as possible before it reaches the guide member, the entanglement of foreign matter with the guide member is reduced. The purpose is to provide a rice transplanter with a simple structure and low cost.

The feature of the present invention is that a protrusion for removing foreign matter is provided on the front bottom surface of the float along near the outer edge of the float, and the rear end of this protrusion is positioned laterally from the groove creator. There is a certain point that
Its effects are as follows.

In other words, by providing the protrusions as described above, the straw debris that mainly floats on the rice field is prevented from entering the front of the trencher as the float moves. , excluded laterally.

Therefore, with a simple structure in which a protrusion is provided on the bottom of the front part of the float, the trencher can be moved on a field surface with less foreign matter, so that the groover can be moved to the guide member disposed in front of the trencher. The entanglement of foreign substances is eliminated. It is also possible to further devise practical applications in which the protrusions are made of inexpensive materials such as strips, and a rice transplanter with a simple structure, low cost, and reduced entanglement of floating straw debris with the guide member can be created. It ended up being donated.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figures 1 and 2, a transmission case 2 receives drive input via a transmission shaft 1 from a passenger traveling vehicle (not shown), and pine-shaped seedlings W are placed in parallel and reciprocated laterally at a constant stroke. Seedling planting section 3, six planting claws 4 for cutting seedlings one by one from the lower end and planting them on the rice field, and three floats 5 swingably attached to the transmission case 2. is configured and is attached to the passenger aircraft via a link mechanism 16 so as to be movable up and down.

In addition, this seedling planting section includes a tank 6 for storing powdery fertilizer, six feeding devices 7 that feed out fertilizer in fixed amounts from the bottom end of the tank using feeding rolls 7a, and six machines for forming fertilization grooves on the field surface. Groove device 8,
A fertilization section is attached, which includes a fertilizer supply hose 9 that connects each feeding device 7 and each furrower 8, and the like. The fertilizing interval is set by attaching the groove cutting device 8 to the rear end of the groove cutting plate 10 arranged on the bottom surface of the float 5, and each fertilizer supply hose 9 has
A flexible drive shaft 12 driven and rotated by a motor 11 is inserted through the hose, and its vibrations promote the flow of powdery fertilizer flowing inside the hose.
In addition, a screw 13 connected to a flexible drive shaft 12 is disposed inside the furrower to forcibly feed powdered fertilizer to the bottom of the fertilization furrow to prevent clogging of the fertilizer in the furrower. , which prevents fertilizer from floating up.

Each of the three floats 5 has a T-shape in plan view, and the two groove plates 10, 10
maintains the spacing approximately at the planting claw 4... spacing, and floats 5.
It is placed on one side of the Also, float 5
The front center of the bottom is a recess 5a that is horizontal by a certain width.
A projecting strip 14 made of a strip plate is formed in the concave portion 5a and is curved so as to substantially follow the outer edge shape of the front part of the float 5 and its rear end is positioned laterally from the groove creators 8, 8.
are attached via brackets 15 at the left and right centers of the protrusions 14. The ridges 14 mainly have the function of removing straw debris floating on the rice field from the field to be fertilized.

Incidentally, in the embodiment of the present invention, the protrusions are arranged on the T-shaped float, but instead of this, it can be implemented by disposing them on a float other than the T-shape.

Further, it is also possible to provide the protrusion 14 by molding it onto the float 5.

[Brief explanation of the drawing]

The drawings show an embodiment of the rice transplanter with a fertilizing device according to the present invention, in which FIG. 1 is a cutaway side view of the seedling planting section, and FIG. 2 is a partially cutaway plan view of the float. 5...Float, 8...Groove cutter, 14...Protrusion.
