Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a seedling replenishing device for a seedling transplanter. As a seedling replenishment device that replenishes seedlings mid-way, it can be used particularly for a riding-type seedling transplanter.

BACKGROUND ART In a multi-row seedling transplanter, there is a technique in which a replenishment seedling stand is provided along the direction in which the seedling tanks of each seedling planting device are lined up to place seedlings to be replenished in the seedling tanks.

Problems to be Solved by the Invention In a multi-row type seedling transplanter, the width of the seedling tank of the seedling planting device in the left and right lateral directions becomes large. The width of the platform also increases, and therefore it is difficult to load seedlings onto this supplementary seedling platform.

Loading seedlings from directly behind is difficult because the distance to the supplementary seedling loading table is large, and loading seedlings from the side requires work on the supplementary seedling loading table in the center, making it difficult to do so.

Means for Solving the Problems This invention provides seedlings that are lined up in the left and right directions (A) with respect to the vehicle body (1) and are fed back and forth in the same direction to feed the seedlings stored therein to the planting device (2). Replenishment seedlings are provided facing the tank (3), parallel to the parallel direction of the seedling tank (3), and are movable endlessly along the same direction, and are to be supplied to the seedling tank (3). A supplementary seedling platform (4) on which seedlings are placed is controlled and interlocked so that as seedlings are placed on this supplementary seedling platform (4), an empty supplementary seedling platform (4) is positioned at one lateral end. This is the configuration of a seedling supply device for a seedling transplanter.

Effect of the Invention Seedlings are placed on each seedling tank (3) and each supplementary seedling stand (4) in advance, and the planting device fii (2) is used to perform seedling planting work by placing seedlings on the left and right sides of each seedling tank (3). When the number of seedlings in the 6-seedling tank (3) in which the seedlings supplied by movement (a) are separated and transplanted decreases, the seedling planting operation is temporarily stopped and the seedlings loaded on the supply seedling platform (4) are individually transplanted. Replenish the corresponding seedling tank (3) and continue seedling planting work. When placing seedlings on this supplementary seedling platform (4), the seedlings are placed from the negative stacked area of this supplementary seedling platform (4). The placed part is rotated endlessly in the direction of moving toward the center, and the primary empty seedling loading platform (4) is fed out to this lateral end, so that it is positioned at this lateral end. Replenishment seedling table (4
Seedlings are supplied sequentially to the first section.

Effects of the Invention As described above, when the seedling loading table (4) receives seedlings, the seedlings are supplied to the feeding seedling loading table (4) at the side end, so that the seedlings are not loaded. The supplementary seedling tray (4) is moved to the center side, and the empty seedling trays (4) are sequentially placed on this side edge, so that each seedling loading tray (4) is loaded with seedlings. It is possible to eliminate the trouble of moving and operating this supplementary seedling loading table (4), and in addition, surface loading only needs to be carried out on the supplementary seedling loading table (4) at the side end, making it easy to load seedlings. can be done efficiently.

Embodiment In the illustrated example, the tractor body (1) has front wheels (5
), it can run by driving the rear wheels (6) with a prime mover (7), and is equipped with a driver's seat (8) and a control handle (9). A support structure is provided by a supporting frame link (Il) on the rear side of the seedling planting device (Il).
n is a connecting link consisting of a four-point link mechanism behind this (
The seedling planting device OD is connected to a hydraulic telescopic cylinder (13) so that it can be raised and lowered by a hydraulic telescopic cylinder (12+).This seedling planting device OD is equipped with a float A4 that slides on the soil surface (+51) on the lower side of the body (+51), and a seedling tank (3) for storing seedlings. A large number of seedling tanks (3) are arranged in series in the left and right lateral directions (A) and are interlocked so that they can move back and forth left and right, and the upper end side is slanted toward the upper front.
) A planting arrangement [(2) is provided opposite the plant. This seedling planting device (11) is powered by a power take-off shaft (Is) at the rear of the vehicle body (1), and the seedlings stored in the seedling tank (3) are supplied to the planting device (2). Separated and transplanted by the planting device (2).

The supply seedling platform (4) is provided by the support frame link + IQ above.

It is installed so that it can be moved back and forth while maintaining a parallel posture, and when the seedling planting device (1υ) is in the raised position, this replenishment seedling platform (4
) can approach or connect to the upper end of the seedling tank (3). Chains (I7) are stretched in the left and right directions on the support frame link (I1) and are provided to be rotated by a motor TI9, and the rows of the pest tanks (3) are adjusted depending on the area. The supplementary seedling tray (4) is installed to match the spacing.The guide frame 12 guides the supplementary seedling tray (4) along the upper side of the Cheno (17).
G is provided. (No. 2 is a popper that accommodates the seedling receiving plate G!+1. I23 is a step.

A sensor or switch (SWI), (SW2) for detecting the presence or absence of seedlings in the guide frame 12G is located at the side end of this Cheno (■).
is provided, and the motor (9) is controlled in conjunction with this switch. (SW3) is a main switch. The switch (SWI) detects when a seedling is placed on the supplementary seedling stand (4) located at the side end and turns on.
Relay contact (R) is turned O by timer relay (T R)
Turn N to rotate the motor (M) and start rotating the replenishment seedling tray (4) toward the center.This relay contact (R) will be OFF, but the switch (SW2) will turn off the replenishment seedling tray. stand (
4) The moving seedling above is detected and turned ON, and the motor (M)
continues to rotate, and this supply seedling stand (4) is turned on by the switch (SW).
2) The circuit is configured in such a way that when the switch (SW2) stops detecting seedlings after passing over the plant, the switch (SW2) is turned OFF and the motor (M) is stopped. At this time, the next empty replenishment seedling platform (4) is at this lateral end position.

The seedlings are bedded seedlings with a square planar shape and are grown in a seedling nursery box, but when feeding them to each supplementary seedling tray (4), use the seedling receiving plate e.
When replenishing the seedling tank (3) by placing it on the N replenishing seedling platform (4) with this seedling receiving plate CI)
) and supply only the seedlings to the seedling tank (3). The above-mentioned switches (SWI) and (SW2) cannot be turned ON by the weight of the seedling receiving plate 1211 alone.

It is configured to turn ON only when it receives seedlings.

When loading seedlings on the supply seedling platform (4), turn the motor (M)
Turn on the main switch (SW3) of
WI) starts the ONL motor (M) to move this replenishment seedling platform (4) to the center side.

Subsequently, the switch (SW2) is turned on by the seedlings on this movable supply seedling platform (4), and the seedling table (4) on which the seedlings are placed is rotated until it passes.

When the empty seedling tray (4) comes to the switch (SW2) position, it will be turned off, so the seedling tray (4) will be stopped.
Waiting for the next seedling to be loaded.

In this way, when the seedlings are filled in the supplementary seedling trays (4) on each upper side, the seedling planting work is resumed.

Note that such switches (SWt) and (SW2) may be provided at both left and right lateral ends.

In this case, it is necessary to switch the rotation direction of the chino (1″71) to the left or right, and a check circuit may be provided to give priority to the switch (SWI) (SW2) on the left or right seedling loading side.
