Description

[Detailed Description of the Invention] The present invention relates to a side marker device that allows a rice transplanter to maintain a predetermined row spacing from adjacent seedlings after seedling planting and to run parallel to the adjacent seedlings.

Conventionally, side markers for adjacent seedlings of this type were
It is configured as a rod-shaped marker that extends perpendicularly from the body of the rice transplanter, but although the rod-shaped side marker serves as a guide for the distance between adjacent seedlings and the rice transplanter, it does not indicate the direction in which the adjacent seedlings and the rice transplanter are moving. Since the parallelism between the adjacent seedlings and the rice transplanter cannot be used as a guideline, the parallelism between the adjacent seedlings and the rice transplanter must depend on the operator's intuition and is therefore inaccurate. Therefore, Utility Model Application Publication No. 52-8618 as a prior art,
It is proposed that side markers be placed parallel to the front and back direction of the rice transplanter, and that these side markers protrude forward from a float located outside of the rice transplanter. If the side marker parallel to the direction protrudes forward from the float, the side marker has a cantilever support structure, so it is easily deformed and damaged.
Moreover, there was a problem in that the tips of the side markers that protruded toward the front of the rice transplanter could pierce and damage seedlings that had already been planted in the field.

The present invention solves this problem, and the gist of the invention is to place a side marker of an appropriate length on the outside of the float, which is located outside the wheels of the rice transplanter, in the longitudinal direction of the rice transplanter. In the case where the side markers are arranged substantially parallel to each other, inwardly directed members are connected to the front and rear ends of the side markers, and the base ends of both of the inwardly directed members are attached to the float.

Below, we will explain an example drawing in which the present invention is applied to a four-row rice transplanter.The figure shows a frame 3 of an engine 2 in the front part of a transmission case 1, and a transmission case 5 in the rear part via a cylindrical frame 4. In the connected fuselage 6, wheels 8, 8 are mounted on the left and right sides of the fuselage 6 so as to be movable up and down via swing arms 7, 7, and a seedling stand 9 and four planting mechanisms 10 are installed at the rear of the fuselage 6. A four-row walk-behind rice transplanter is shown, which is equipped with a seedling transplanting device 11 and a pair of control handles 12, and a float 13 with the same length as the lower part of the body 6, and wheels 8, 8. Floats 14, 14 are provided on the outside so as to slide on the field area 15, respectively, and the rear ends of these floats 13, 14, 14 are attached to a part of the body such as the base of the handle 12 with a seedling depth adjustment rod 16. The front end of the float 13 at the bottom of the fuselage 6 is attached to the bottom of the engine frame 3, and both outer floats 1
The front ends of the swing arms 4 and 14 are attached to the tips of horizontal bars 7 and 7 extending outward from the base ends of the swing arms 7 and 7 via links 18, 19 and 19, respectively, so as to be vertically movable.

Reference numeral 20 indicates a side marker made of a round bar, which is disposed on the outer side of the upper surface of the floats 14, 14, which are located on the outer side of the wheels 8, 8, so as to extend parallel to the front-rear direction of the rice transplanter. The front and rear ends of 20 are bent inward to connect the inward members, and the base ends of both the inward members are connected to the float 1.
It is attached to 4.

As shown in FIG. 4, these side markers 20, 20 are configured to be able to extend and contract upwardly or outwardly with respect to the float 14, and from the planting mechanism 10 located on the outside to the outer ends of both side markers 20. Dimension L
is set equal to the row spacing L between each planting mechanism 10.

In this configuration, when seedling mats are supplied to the seedling platform 9 and driven by the start of the engine 2, the machine body moves forward with both wheels 8, 8, while each seedling planting mechanism 10 swings up and down simultaneously. By doing this, the seedlings on the seedling platform 9 are divided one by one by the vertically swinging seedling planting mechanism 10, and then the seedlings are placed on the floats 13, 1 in advance.
After leveling the land in steps 4 and 14, the rice can be planted in sequence along four rows in field 15, and the rice transplanter can be planted at the edge of the bank.
The rice transplanting operation is carried out by turning the rice transplanter in a direction of 180 degrees and moving the rice transplanter so that either the left or right side marker 20 follows the previous seedling planting row.

In this case, the side marker 20 of the present invention has a structure in which the length is appropriately extended parallel to the vertical direction along the traveling direction of the rice transplanter as described above, so that the side marker 20 of the present invention By running the rice transplanter in such a manner, the distance between adjacent shoots can be maintained constant, and the parallelism of the rice transplanter to the adjacent shoots can be controlled by the parallelism between the side marker 20 extending in the direction of movement of the rice transplanter and the adjacent shoots. This allows the rice transplanter to be accurately and easily run parallel to adjacent shoots without relying on the operator's senses as in the past.

Moreover, in the present invention, inwardly directed members are connected to the front and rear ends of the side marker 20, and the proximal ends of both inwardly directed members are attached to the float 14, so that the side marker 20 has both ends It serves as a support structure and does not easily deform, and due to the presence of the inward facing member at the front end of the side marker 20, the front end of the side marker 20 can be attached to a seedling that has already been planted as in the prior art. There is no piercing effect.

Therefore, according to the present invention, the side markers that extend parallel to the front and rear directions of the rice transplanter allow the rice transplanter to run reliably along adjacent seedlings that have already been planted, while also ensuring that the side markers are not deformed or damaged. This has the effect of not only being able to prevent damage to already planted seedlings by the side markers, but also being able to reliably avoid damaging the seedlings that have already been planted.
