Abstract

<P>PROBLEM TO BE SOLVED: To surely feed seedlings without entwining roots with seedling feeding operation parts and without damaging the seedlings in a seedling transplanter for transferring matlike seedlings in a state of receiving the bases of the matlike seedlings to prescribed seedling takeout positions with the caterpillar type seedling feeding operation parts, taking out the seedlings at the seedling takeout positions and transplanting the seedlings in a field. <P>SOLUTION: The seedling transplanter is obtained by installing protruding ridges 102a having a smaller width than that of the seedling feeding operation parts 102 in the direction crossing with the seedling feeding direction at a suitable interval on the surfaces of the seedling feeding operation parts 102. The mutual protruding ridges 102a adjacent in the seedling feeding direction are shifted in the width direction of the seedling feeding operation parts 102 and arranged. <P>COPYRIGHT: (C)2004,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the use of mat-shaped seedlings.
Seedling transfer technology in a seedling transplanter. [0002] In a seedling transplanter using mat-shaped seedlings,
The seedling platform on which the seedlings are placed reciprocates left and right, and the seedlings at the bottom
The seedlings are supplied to the discharge position, and the seedling removal tool
Split and take out and plant in the field, and the seedling stand is on the left
Move to the end of the right path and plant all the seedlings in a row.
The seedling feed belt provided on the seedling table is activated,
The upper mat seedlings were transferred to the side of the seedling removal position
I have. Make sure that the seedling feed belt and the seedlings
Next, as shown in FIG.
Wart-like projections 102b were provided. [0003] However, the above-mentioned
The new seedling feed belt makes it easy for roots to get entangled
The seedlings are damaged and the feeding of the seedlings becomes unstable
Had such problems. The present invention addresses this conventional problem.
Eliminate spots and ensure that seedlings can be sent without damaging the seedlings
The challenge is to: [0004] In order to solve the above problems,
The present invention has the following configuration. That is, the present invention
The seedling transplanter has a mat-shaped seedling feeder
Take the seedling to the specified seedling removal position while receiving the bottom of the seedling.
Transfer, take out seedlings at the seedling removal position and plant in the field
In the seedling transplanter, the seedling feeder is placed on the surface of the seedling feeder.
Projecting in a direction that is shorter than the width of the
Protrusions are provided at appropriate intervals and are adjacent to each other in the seedling feed direction.
It is noted that the nurses were shifted in the width direction of the seedling feeder.
It is a sign. [0005] The ridges are caught on the bottom surface of the seedlings to feed the seedlings.
Prevent slippage between the belt and the seedlings and send the seedlings securely. Ridge is a seedling
Since it is provided over the entire width of the feeder,
Any part in the width direction of the feeding operation body performs the seedling feeding action. Ma
Also, the ridges before and after adjacent to the seedling feeder in the seedling feed direction
Is shifted in the width direction of the seedling feeder.
Even if the ridge is short, there is no uneven seedling feeding in the seedling feeding direction.
No. [0006] Therefore, the seedling transplanter according to the present invention,
The root of the seedling is entangled with a long ridge in the width direction of the seedling feeder
So that the seedling feed belt does not damage the seedlings,
In addition, the seedlings can be reliably and stably sent to the seedling removal position.
The accuracy of seedling planting has been improved. Preferred embodiments of the present invention will be described below.
The state will be described. 1 to 3 show seedling transfer according to the present invention.

Angle (floating angle) is the ground height detection mechanism 218
Is detected by the float angle sensor 219 via the
The hydraulic valve 58 is driven based on the output result. An example
For example, where the topsoil surface is high,
The front of the funnel 210C is pushed up and the float is facing
Is detected small. Then, the hydraulic cylinder 56 protrudes.
An output command is issued to the hydraulic valve 58 so that the
The planting part 4 is raised. Also, the topsoil surface is low
By the way, the front of the center float 210C goes down
Therefore, a large facing angle is detected. Then, the hydraulic syringe
Output finger to the hydraulic valve 58 so as to contract the
And the seedling planting section 4 is lowered. Thus, the field
The height of the seedling planting section 4 above the ground is controlled according to the height of the topsoil surface.
This keeps the planting depth of the seedlings constant. The seedling transplanter 1 is used for planting seedlings during transportation and storage.
