Description

TECHNICAL FIELD The present invention relates to a seedling feeding device for a seedling planting machine.

[Conventional technology]

Conventionally, the seedling feeding section of the seedling tank has a seedling separating opening for operating the seedling planting tool from above to separate the seedlings, and scrapes out the stored seedlings in the seedling tank to the seedling separating opening side. The seedling supply device was provided with a fork and did not have a seedling receiving frame or the like that operates toward the seedling separation port when the scraping fork is operated.

[Problems to be Solved by the Invention]

When the seedling tank of the seedling planting machine is loaded with rush seedlings and the transplanting of the rush seedlings is carried out, the operator gets on the driver's seat and the front and rear traveling wheels on the left and right sides rotate to drive the seedling planting machine. The center float provided on the rear of the seedling planter and the side floats on both left and right sides slide on the running soil surface to the ground, and the grass seedlings to be loaded into the seedling tank are swept by a fork to the soil surface prepared by each of these floats. At the same time it is scratched towards the seedling separation side,
By oscillating drive of the seedling planting device, the rush plant is separated from the seedling separating port, and this rush plant is transplanted. However, the rush plant is not in a mat-like shape but is loaded in a state where each one is separated, Therefore, when the seedling separation tool is separated from the seedling separation opening, the rush seedlings on both sides of the seedling separation opening may be squeezed out, which may cause variations in the number of transplants.
The aim is to eliminate this and stabilize the number of transplants.

[Means for Solving the Problems]

In order to solve the above-mentioned problems of the prior art, the present invention operates a seedling planting tool (3) in the seedling feeding section (2) of the seedling tank (1) from above to below to separate seedlings ( 4)
At the left and right edges (5) of the seedling tank (1), the picking fork (6) for picking up the seedlings contained in the seedling tank (1) toward the seedling separating port (4) side is at the lower side in the picking direction. A seedling receiving frame (7) which operates from the inside to the seedling separating port (4) to receive the front surface in the scraping direction on the left and right end sides of the scraped seedling and allows the seedling planting tool (3) to pass therethrough. It is used as a seedling feeding device for the seedling planting machine.

[Operation of the invention]

Load sapling seedlings into the seedling tank (1) of the seedling planter as described above,
When transplanting this rush seedling, the operator gets on the driver's seat and the front and rear traveling wheels rotate to drive the seedling planting machine. The running soil surface is grounded, and the grass seedlings to be loaded into the seedling tank (1) are scraped out to the seedling separation port (4) side by a scraping fork (6) onto the soil surface prepared by each of these floats. At the same time as the seedling feeding portion (2) of the seedling tank (1) is fed, the seedling receiving frame (7) is placed inside the seedling separating opening (4) during the scraping operation of the scraping fork (6). The grass seedlings that have moved to the left and right side edges (5) are partitioned, and this partitioning seedling seedling is separated from the seedling separating port (4) by the operation of the seedling planting tool (3), and this seedling seedling is transplanted. To be done.

〔The invention's effect〕
