DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paddy field fertilizer for applying liquid or granular fertilizer to paddy fields.

[0002]

2. Description of the Related Art Conventionally, a paddy field fertilizer is constructed by connecting a plurality of floats provided with fertilizers to a rear part of an airframe having wheels and forming the floats in a gate- like shape having an open rear in plan view. Already known.

[0003]

As described above , the float of the paddy field fertilizer applicator has a gate-like shape with an open rear in plan view.
Although the float is already known, the part of this float that extends toward the left and right rear of the opening is configured to be approximately the same width, and the fertilizer is installed in the middle of the width of the opening, so The fertilizer was applied to the roughened area near the wheel mark, and the fertilization position was unstable. Even if the width of the float is widened to improve such a problem, the width cannot be widened because the width is limited by the space between the side fertilizers.

[0004]

The present invention SUMMARY OF] is the rear of the machine body with wheels, planting body 19 and the side strip fertilization member 22 by connecting a plurality of floats 20 which are oppositely arranged, the side strip fertilization instrument 22
In paddy for fertilization machine so as to fertilization in the soil by sending a fertilizer, a float 20 which faces the rear of the wheel, the long back and forth
The front portion of the inner wide portion 20a and the outer narrow portion 20b having substantially the same length are connected to each other to form a portal shape with a rear opening in plan view, and the wide portion 20a is formed. is opposed immediately after the wheels, side Article fertilization member 22 on the opening side in close proximity thereto on the outside of the narrow portion 20b, before and after the discharge portion of the opening
As well as arranged so as to be positioned substantially intermediate portion with planted planting seedlings inside of the upper of the opening side Article fertilization tool 22 body 1
The above-mentioned problem has been solved by providing the fertilizer application position 9 and separating the fertilization position to the side with the wheel mark while sufficiently leveling the wheel mark with the wide portion of the float.

[0005]

[Function] When the airframe is run while sending the fertilizer, the float slides while leveling the rice field, and the sent fertilizer is fertilized in the soil by the fertilizer. At that time, the wide part of the float facing immediately after the wheel flattens the wheel traces wide, and the fertilizer is inside the narrow part on the side across the opening from the wide part,
In other words, fertilizer is applied to a predetermined position in a portion largely separated from the wheel mark without being affected by the wheel mark, and the outside thereof is leveled by the narrow portion.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a riding fertilizer seedling planting machine shown in the drawings. A main frame 1 is composed of an upper frame 2 and a lower frame 3, and the upper frame 2 The front portions of the upper vertical frames 2a, 2a are connected by being bent inward, and a little forward from the middle is welded by the upper horizontal frame 2b, and the rear portion is upwardly curved in a side view so as to be curved and projected in a plan view. The lower frame 3 is formed by welding to the outside of the front middle portion of the U-shaped connecting member 2c having a rear opening.
The front ends of the lower vertical frames 3a, 3a having a smaller interval than a are welded to the transmission case mounting plate 5, and the rear portion is connected to a lower horizontal frame 3b extending to both sides to form a frame body. The upper part of the transmission case mounting plate 5 is welded to the upper horizontal frame 2b in the middle of the upper frame 2, and the horizontal pipes 8 are welded to the seat frames 7, 7 erected at the rear of the lower frame 3, and both ends thereof are connected to each other. The connecting member 2c is fixed to the inner surface near the top of the member 2c.
