Description

[Detailed Description of the Invention] The present invention relates to a line marker used when planting seedlings by running a rice transplanter in a field.

Generally, the plowed soil in a field is very soft, and even if a line is drawn on the soil surface with a marker, the line will be erased by the collapse of the soil surface.

Furthermore, when the rice transplanter runs, the soil surface is disturbed, causing the soil surface near the line to collapse further, causing the line to be erased.

Therefore, the present invention was devised to solve such problems, and its purpose is to be able to reliably form clear lines on the plowed soil surface in the field, and also to ensure that the soil surface does not change as the rice transplanter runs. To provide a line marker for a rice transplanter in which there is no fear that the soil surface near the disturbed line will collapse and the line will be erased.

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

The rice transplanter, which is generally shown on the upper floor 1 in the figure, has a prime mover 3 mounted on a body 2 having a steering handle 11, and transmission cases 5, 5 that are swingable on both sides of the body 2.
The wheels 4, 4 are supported through the transmission cases 5, 5, and the wheels 4, 4 are connected to the prime mover 3 through an appropriate transmission mechanism in the transmission cases 5, 5.
A float 6 is provided at the lower part of the fuselage 2, and the front and rear parts of the float 6 are pivotally connected to the fuselage 2 via appropriate links to support the float 6. A planting claw 7 is provided at the rear of the machine body 2 and is connected to the prime mover 3 and driven while drawing a predetermined trajectory, and the rear end portion is located on the body 2 within the trajectory of the planting claw 7. Equipped with a seedling stand 8 with a high front and a low rear, and this seedling stand 8
a reciprocating device 9 which is driven by being interlocked with the prime mover 3;
It is configured to move back and forth along the L-shaped guide rod 10.

This rice transplanter 1 is already known, and detailed explanation of its structure and operation will be omitted.

Thus, in the present invention, line drawing markers 12, 12 are provided on both sides of the rice transplanter 1 constructed as described above, and the line drawing markers 12, 12 will be explained below.

A support rod 13 is attached to a guide rod 10 that is fixedly supported on the fuselage 2.
The support bracket 13 is fixedly supported through the support bracket 13, and the plate body 14 is pivotally attached to the support bracket 13 with one bolt 15 extending in the direction of movement of the aircraft body 2.
One end of a cylindrical shaft 16 extending in the lateral direction of the fuselage 2 is fixed to the cylindrical shaft 16 , one end of a shaft rod 17 is inserted and fixed into the free end of the cylindrical shaft 16 , and the end of the shaft 17 is fixed in the lateral direction of the fuselage 2 . The cylindrical body 18 is rotatably inserted into the protruding end portion while protruding outward,
The upper end of the line marker 12 is fixed to the cylindrical body 18, and the line marker 12 is bent near the road edge at an obtuse angle θ so that its free end points toward the rear in the direction of movement of the aircraft 2, and then touches the ground. In addition, the cross-sectional shape of the grounding side of this grounding part is a triangle with the apex located approximately at the center as shown in FIG. Concave the hypotenuse inward,
The ground contact portion includes a sharp earth cutting portion 12a′ facing the ground, and upper pressing portions 12b, 12 continuous to both sides of the earth cutting portion 12a and pressing the soil to be pushed aside by the earth cutting portion 12a.
b.

In the figure, reference numeral 19 denotes a limiter bent in an L-shape, and the limiter 19 is fixed to the shaft rod 17 to limit the rotatable range of the line marker 12 in the forward direction (clockwise in the figure). are doing.

In the figure, reference numeral 20 denotes a handle fixed to the cylinder shaft 16, and the cylinder shaft 16 is rotated to stand up by holding the handle 20 or stepping on it with one's foot.

In the figure, reference numeral 21 denotes a coil spring wound around the outer periphery of the cylindrical body 1B, one end of which is connected to the line drawing marker 12.
In addition, the other end is latched to the limiter 19, acting to constantly rotate the line drawing marker 12 in the forward direction.

In the figure, reference numeral 22 denotes a coil spring interposed between the handle 20 and the support bracket 12, and when the coil spring 22 is located on the left side of the bolt 15 in FIG. It acts to maintain the cylinder shaft 16 in the collapsed position (marker use position), and also functions to maintain the cylinder shaft 16 in the upright position (marker storage position) when located on the right side, forming a so-called unstable switching mechanism for the cylinder shaft 16. are doing.

Further, the cross-sectional shape of the free end side of the line drawing marker 12 has a shape as shown in FIG. 6, but it may also have a shape as shown in FIGS. 7A and 7B.

The delineation marker 12 of the present invention is constructed as described above, and when the delineation marker 12 is not in use, for example, when the rice transplanter 1 is running on the road, the cylindrical shaft 16 is rotated to stand up. is folded and stored on the side of the fuselage 2, and when in use, the cylinder shaft 16 is rotated so as to lie down so that the line drawing marker 12 protrudes laterally outward from the fuselage 2, and the free end of the marker 12 is The machine 2 plunges into the soil surface after plowing in the field, and the machine 2 travels to draw a line on the soil surface.

However, when the lever is drawn, the sharp earth cutting part 12a of the ground contact part of the marker 12 scrapes the soil surface on both sides, and the soil scraped on both sides is held down by the upper pressing surfaces 12b, 12b which are concavely curved in an arc. Can be attached.

Therefore, the line formed on the soil surface has a cross-section with a cross-sectional shape, and both side walls have smooth arc-shaped surfaces and are shaped so that they continue to the soil surface.

As explained above, the wire-drawn marker according to the present invention has a ground-contacting portion formed by bending the free end portion of the wire-drawn marker at an obtuse angle toward the rear in the traveling direction of the aircraft, and the cross-sectional shape of this grounding portion on the grounding side. is formed into a substantially triangular shape with the apex located approximately in the center, with the apex facing the ground, while the oblique sides located on both sides of the apex are concavely curved inward;
The earth-contacting part is characterized in that a sharp earth cutting part facing the ground is formed, and upper pressing parts are formed continuously on both sides of the earth cutting part to press the soil that is moved by the earth cutting part. Therefore, when drawing a line on the plowed soil surface in the field, the cut portion of the grounding part plows the soil surface on both sides, and the soil plowed on both sides is separated by the upper pressing surfaces. Being held down.

Therefore, the line formed on the soil surface has a cross-sectional shape, and both side walls have smooth arcuate surfaces that continue on the soil surface, which indicates that the soil is very soft. Also, during this line drawing, the soil surface does not collapse and the line drawings are not erased, and a clear line drawing can be extremely reliably formed on the soil surface.

In addition, the soil surface is disturbed as the rice transplanter runs, and since the line formed using the marker according to the present invention is shaped while being pressed as described above, the soil surface near this line is disturbed. There is no so-called collapse, and there is no fear that this delineation will be erased.

Furthermore, according to the line-drawing marker of the present invention, the amount of unused soil during line-drawing can be reduced, so that the line-drawing resistance caused by the marker can be reduced, and the ground-contacting part of the line-drawing marker can be well penetrated into the soil. be.
