Abstract

PURPOSE:To enable the sure supporting of seedlings held by a planting rod with a seedling chuter during the transfer of the seedlings to the paddy field surface even if the amount of the seedlings scraped with the planting rod varies by an increase or a decrease in a transplanter designed to scrape the seedlings from a seedling carrying-platform installed in a mobile machine body with a planting rod capable of performing planting operations and plant the seedlings in the paddy field surface. CONSTITUTION:This seedling chuter structure is constructed by installing a seedling chuter 18 composed of an elastic unit for supporting scraped seedlings (P) in the direction of a planting operation locus (A) of the planting rod on the side of a machine body near a seedling receiving plate 8, forming a contact part 20 where the vertically moving seedling receiving plate 8 rides thereon to elastically change the posture of the seedling chuter 18 and increasing the interval between the seedling chuter 18 and the planting operation locus (A) interlocking with the regulation of the amount of the scraped seedlings with the vertically moving seedling receiving plate 8 when the amount of the scraped seedlings is large and decreasing the interval when the amount of the scraped seedlings is small.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling shooter structure provided in a planting portion of a transplanter such as a multi-row planter transplanter.

[0002]

2. Description of the Related Art Generally, from a seedling table provided on a traveling body,
In a transplanter such as a multi-row planter planting machine in which the planting rod that operates to plant the seedlings scrapes the seedlings and plants them on the paddy field, the seedlings scraped from the seedling mounting table and held on the planting rod are planted on the paddy field. In order to prevent the seedling posture from being disturbed and falling off as much as possible, it is known to support the seedling shooter attached to the planting rod along the locus of planting operation.

[0003]

However, in the conventional transplanter, the mounting position of the shooter shooter does not change regardless of the amount of seedlings held on the planting rod. When the amount of seedlings held by the rod changes, the support condition of the seedlings by the seedling shooter also changes, so there is a problem that the seedling posture is disturbed until the rice field and the planting accuracy is not stable. Also, if you try to support the seedlings in a proper condition all the time, you have to remove the seedling shooter and change the mounting position every time you adjust the scraping amount of the seedling. There was an inconvenience. The present invention was created in view of the actual situation as described above,
By adjusting the amount of seedlings scraped, even if the amount of seedlings held by the planting rod increases or decreases, the seedlings should be supported in a proper condition according to the amount of seedlings until the paddy field. It is an object of the present invention to provide a seedling shooter structure of a planting part in a transplanter capable of improving the planting accuracy without causing disorder of the plant.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the technical means taken by the present invention is that a planting rod, which is planted and operated from a seedling mounting table provided on a traveling machine body, scrapes off the seedlings. In a transplanting machine designed to be planted in, a seedling shooter for supporting the scraped seedlings is provided toward the planting operation trajectory of the planting rod, and the planting operation trajectory of the seedling shooter and the planting rod is The width of the seedlings can be adjusted to be wide or narrow according to the amount of seedlings scraped, and the seedling receiving plate at the lower end of the seedling mounting table is arranged so as to be vertically movable, and the seedling receiving port of the seedling receiving plate is arranged. In the transplanter in which the planting rod that operates the planting scrapes the seedlings and plants them on the rice field, a seedling shooter that supports the scraped seedlings is directed toward the planting operation locus of the planting rod. Along with the provision of the seedling shooter, the seedling shooter is linked to the adjustment of the seedling scraping amount of the vertically moving seedling support plate, The distance between the attachment rod and the locus of planting operation can be adjusted to be wide or narrow according to the amount of seedlings scraped, and furthermore, the machine side near the seedling support plate is made of an elastic body that supports the scraped seedlings. Attach the seedling shooter toward the planting operation path of the planting rod, and form a contact part on the seedling shooter that moves up and down to elastically transform the seedling shooter. The interval between the shooter shooter and the planting rod operation path is set to be wide when the seedling scraping amount is large and narrow when the seedling scraping amount is small, in conjunction with adjusting the seedling scraping amount of the moving seedling support plate. It is a feature.

[0005]

Therefore, according to the present invention, when the seedling scraping amount is adjusted, the planting shooter with the interval between the planting rod and the planting operation locus is adjusted according to the seedling scraping amount. The seedlings held on the rod can be supported. Also, in the case where the seedling shooter is linked to the seedling scraping amount adjustment, by vertically moving the seedling receiving plate, the seedling shooter whose spacing between the seedling shooter and the locus of the planting operation is wide and narrow is used to remove the seedlings held on the planting rod. Can be supported,
In addition, in the case where the seedling shooter has a contact part, the vertically moved seedling support plate rides on the contact part and elastically transforms the seedling shooter made of an elastic body, and the distance from the planting operation trajectory is When the amount of scraping is large, the shooter that is wide is used, and when it is small, the shooter is narrowed to support the seedlings held by the planting rod. Therefore, even if the scraping amount of seedlings is adjusted, the seedlings held by the planting rods are not properly supported by the seedling shooter in a proper state until they reach the paddy field, and the seedling posture is disturbed or dropped. There is nothing to do.

[0006]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference numeral 1 denotes a planting part connected to the rear part of the traveling machine body, and as shown in FIG. 1, is composed of a seedling stand 2, a drive case 3, a planter case 4, a float 5 and the like. The seedling placing table 2 is erected in a front-high and low-lower manner, and is adapted to reciprocate left and right in conjunction with a lateral feed mechanism 6 provided in the drive case 3. A lower rail 7 supports the seedling mounting table 2. Reference numeral 8 denotes a seedling receiving plate disposed so as to face the lower end of the seedling mounting table 2, and the seedling receiving plate 8 has a base end portion 8a.
Is mounted so as to be vertically slidable along the side surface of the stay 9 fixed to the body side. Further, the planter case 4 arranged below the seedling placing table 2 is provided with a shaft 10 for transmitting power from the drive case 3 at a front end thereof, and a planter shaft 11 at a rear end thereof. A planter case 12 of a rotary type plant that rotates as a center is provided. 13, 13 is the planter case 12
A pair of planting rods provided on the planting rod, and a bifurcated beak 14 for scraping off the seedlings and a fork 15 for pushing out the seedlings scraped and held by the beaks 14 are attached to the planting rods 13. With the rotation of the planter case 12, the tip of the beak 14 rotates along the planting operation locus A, scraping and holding the seedlings of the unit planting plant from the seedling take-out port of the seedling receiving plate 8. After that, when reaching the rice field, the fork 15 pushes out the seedlings and plants them. The seedling scraping amount of the beak 14 can be increased or decreased by adjusting the vertical movement of the seedling receiving plate 8. 16 is float 5
It is a bent link that supports up and down freely. A seedling shooter 18 made of an elastic material is attached to the mounting member 17 provided on the lower surface side of the stay 9, and a planting operation locus A of the planting rod 13 is provided.
It is attached and fixed by a mounting bolt 19 toward.

As shown in FIG. 2, the seedling shooter 18 is
A bent portion a that extends downward from the position of the mounting bolt 19 to the seedling receiving plate 8 side and is inverted and bent downward is formed at a position in the vicinity of the side surface of the stay 9, and the hanging portion b is on the planting operation locus A. It is curved along and faces the bifurcated beak 14. The bent portion a projects toward the seedling receiving plate 8 as it approaches the planting operation locus A, and the contact portion 20 with the seedling receiving plate 8 is formed in an inclined shape, depending on the seedling scraping amount. Seedling shooter 1
The distance between 8 and the planting operation locus A can be adjusted to be wide or narrow. That is, if the seedling receiving plate 8 is moved downward in order to increase the amount of scraped seedlings, the base end portion 8a of the seedling receiving plate 8 rides on the abutment portion 20 and the planting operation locus A of the bent portion a is reached. Since the seedling shooter 18 made of an elastic material is pressed at a close position, the seedling shooter 18 elastically transforms in the direction of the arrow (a) where the distance between the hanging portion b and the planting operation locus A becomes wider and is supported by the planting rod 13. Support a large amount of seedlings P. On the other hand, if the seedling support plate 8 is moved upward in order to reduce the scraping amount of the seedlings, as shown in FIG.
Is retracted from the abutment portion 20 and slidably contacts only the stay 9 side of the bent portion a, so that the seedling shooter 18 has a narrower interval between the hanging portion b and the planting operation locus A in the arrow (b) direction. The seedlings P that are elastically deformed and supported by the planting rods 13 in a small amount are supported.

FIG. 4 shows another embodiment in which the interval between the seedling shooter and the planting operation locus A can be adjusted to be wide or narrow according to the seedling scraping amount. That is, 21 is a mounting bolt for fixing the seedling shooter 22 to the mounting member 17, and the mounting bolt 2
1 is arranged in a slanting shape toward the upper front, and the base end portion of the seedling shooter 22 is fixed to the mounting bolt 21 with a nut 23. A coil ammunition 24 is interposed between the seedling shooter 22 and the mounting member 17. The seedling shooter 22 is similar to the above-described one in that the hanging portion that is inverted and bent downward is curved along the planting operation locus A. Then, if the nut 23 is strongly tightened according to the amount of seedling scraping, the coil ammunition 24 is reduced and the seedling shooter 22
When the whole is displaced along the mounting bolt 21 in the upper front direction, that is, in the direction of the arrow (c) where the distance from the planting operation locus A is widened and the nut 23 is loosened, the coil ammunition 24 extends and the seedling shooter 22. The whole is displaced downward along the mounting bolt 21 in the rearward direction, that is, in the arrow (d) direction in which the interval with the planting operation locus A is narrowed.

In the above construction, the beak 14 of the planting rod 13 for planting scrapes the seedlings of the unit planting plant from the seedling take-out port of the seedling support plate 8 to the paddy field in performing the transplanting work. Plant it. At this time, the seedlings scraped and held by the beak 14 are supported from below by the seedling shooter 18 provided toward the planting operation locus A of the planting rod 13 until it reaches the rice field and is planted. Then, when the seedling receiving plate 8 is moved downward to increase the amount of scraped seedlings, the base end portion 8a of the seedling receiving plate 8 rides on the abutment portion 20 of the seedling shooter 18 to plant the seedling shooter 18. When the seedling support plate 8 is elastically deformed in a direction in which the distance between the rod 13 and the planting operation locus A is widened and the seedling support plate 8 is moved upward to reduce the amount of scraped seedlings, the base end portion 8a of the seedling support plate 8 is The seedling shooter 18 is retracted from the contact portion 20 and elastically deforms in a direction in which the interval between the planting rod 13 and the planting operation locus A is narrowed. Therefore, the seedling shooter 18, which is elastically transformed in connection with the adjustment of the seedling scraping amount, supports the seedling held by the beak 14 of the planting rod 13 in an appropriate state according to the seedling scraping amount at all times. The seedling posture will not be disturbed or dropped. Further, in the one shown in FIG. 4, the seedling shooter 22 can be entirely displaced by simply adjusting the nut 23 while the seedling shooter 22 is attached at a predetermined position. Even with a transplanter that adjusts the amount taken, it is possible to easily adjust the distance between the seedling shooter 22 and the planting locus A according to the amount taken up by the seedling to support the seedling in an appropriate state. it can.

In summary, the present invention provides a transplanter in which a planting rod which is planted from a seedling mounting table provided on a traveling machine body scrapes off the seedlings and plants them on the rice field. A seedling shooter that supports scraped seedlings is provided toward the planting operation trajectory, and the distance between the seedling shooter and the planting operation trajectory of the planting rod can be adjusted wide or narrow according to the seedling scraping amount. In addition, the seedling receiving plate at the lower end of the seedling mounting table is arranged so as to be vertically movable, and a planting rod that operates to plant the seedlings scrapes the seedlings from the seedling receiving port of the seedling receiving plate to plant them on the rice field. In the transplant machine,
A seedling shooter for supporting the scraped seedlings is provided toward the planting operation locus of the planting rod, and the seedling shooter is
In association with the adjustment of the seedling scraping amount of the vertically moving seedling support plate, the interval between the seedling shooter and the planting operation locus of the planting rod can be configured to be wide or narrow according to the seedling scraping amount, and further, Attach a seedling shooter made of an elastic body that supports scraped seedlings to the side of the machine near the seedling support plate, facing the trajectory of the planting rod's planting operation. The board rides up to form an abutment part that elastically transforms the shooter shooter, and the spacing between the shooter shooter and the planting operation trajectory of the planting rod is linked with the adjustment of the seedling scraping amount of the vertically moving seedling receiving plate. Is configured to be wide when the seedling scraping amount is large and narrow when the seedling scraping amount is small. Therefore, if the seedling scraping amount is adjusted according to the working conditions, the planting rods can be planted according to the seedling scraping amount. The seedlings held on the planting rod can be reliably supported by the seedling shooter whose distance from the locus is adjusted to be wide and narrow. And in the case where the seedling shooter is linked to the seedling scraping amount adjustment, the distance between the seedling shooter and the planting operation locus can be adjusted widely depending on the seedling scraping amount by simply moving the seedling support plate up and down. In the case where the contact part is formed on the shooter, the seedling shooter elastically transforms in conjunction with the vertically moving seedling support plate, and the distance from the planting operation trajectory is wide when the seedling scraping amount is large and when it is small. Since the seedlings that are narrowed and held on the planting rod are supported, the seedlings can always be supported reliably in an appropriate state regardless of the amount of scraped seedlings. The planting accuracy can be improved without causing any problems.
