Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a seedling supply device for a seedling transplanter, and the present invention relates to a seedling supply device for a seedling transplanter, and a seedling support stand for receiving supplementary seedlings, which is provided separately from a seedling tank of the seedling planting device, is used to supply seedlings. It is effective when used in a single-rider type seedling transplanter as it makes it easier to perform the operation.

Conventional technology The supply seedling stand is installed on the rear of the traveling vehicle body (5).

This is an operating mechanism that can be switched forward and backward as necessary using an operating lever of a control device or the like.

Problems to be Solved by the Invention Replenishment of the seedling transplanter The replenishment of seedlings to the seedling stand is done separately from the supply of seedlings to the seedling tank of the seedling planting device, and it is necessary to stop the seedling transplanter from running at the edge of a ridge, etc. The supplementary seedlings are directly placed on the supplementary seedling platform, and during seedling planting work, the seedlings are supplied from this supplementary seedling platform to the seedling tank. Frequently perform switching operations to move the replenishing seedling stand back and forth, such as moving it backwards to make it easier to replenish seedlings, or moving it forward to make it easier to feed seedlings to the seedling tank. However, especially in the case of a riding-type seedling planting machine, the distance or attitude between the operating position of the passenger seat and the position where the supplemented seedlings are loaded changes significantly, so the switching operation is complicated and tends to take a long time.

Means for Solving the Problems This invention provides a seedling tank (2) for storing seedlings (1) and a planting device for transplanting the seedlings (1) supplied from the seedling tank (2). (A seedling planting device (4) consisting of 31, etc. is mounted on the rear side of a traveling vehicle body (5) that is movable up and down (B) at the rear side in the seedling traveling direction (A). A supplementary seedling loading stand (6) is installed along the line C) and placing the supplementary seedlings (1) to be supplied to each of these seedling tanks (2), and all of these seedling loading stands (6) are connected to the supplementary seedling (1). ), this supplementary seedling platform (6) is moved to the front position (d), and when any of the supplementary seedling platforms (6) becomes empty, this supplementary seedling platform (6) is moved. A seedling replenishing device for a seedling planting machine is provided with a seedling table moving device (7) that moves to a rear position (E).

Functions and effects of the invention When planting seedlings (1) by moving the traveling vehicle body (5) in the seedling planting traveling direction (a), the seedling planting device (4) is in the lowered position and the seedling tank ( The seedlings housed in the seedling tank (2) are transplanted by the planting device (3), and the seedlings are transplanted into the seedling tank (
When the number of seedlings (1) in 2) decreases, the running of the vehicle body (5) is temporarily stopped, the seedling planting device (4) is raised, and the seedlings (1) on the replenishing seedling platform (6) are removed. This seedling tank (2
).

When there are no more seedlings (1) on this seedling platform (6), the running vehicle (5) is stopped at a seedling replenishing position such as the edge of a ridge during an appropriate work process, and the seedlings are placed behind the seedling planting device (4). Seedlings are replenished from the side to the seedling tray (6), but if the seedling tray moving device (7) is activated at this time, the seedlings (1) on the seedling tray (6) will become empty. This will allow you to supply seedlings (
6) is automatically moved to the rear position (E), and is in a position where it is easy to reach this replenishment seedling loading table (6) from the edge of the ridge, etc., so that seedlings can be easily replenished.

When a supplementary seedling (1) is placed on all supplementary seedling platforms (6), this supplementary seedling platform (6) is automatically placed in the front position (d).
Since these seedlings (1) are in a state where they can be moved to the seedling support stand (6), the seedling support stand (6) is moved to the front position (d) or the rear position (c). No need to operate.

Embodiment In the illustrated example, the traveling vehicle body (5) has a front axle (8) and a rear axle (9) like a four-wheeled tractor, and has a prime mover +II, a control handle (1υ), and a driver's seat (121, etc.). At the rear of this is a connecting rod (10
A seedling planting device F (41) consisting of a float (141, a seedling tank (2), a planting device (3), and a transmission case (19) housing a transmission mechanism) is connected to the traveling vehicle body (5).
The structure is such that power can be transmitted from the power output shaft. (
+19 is a step installed at the rear end of the transmission case (1!9).The seedling tank (2) is integrally connected to the left and right sides (A) in multiple rows, and moves back and forth along the same direction. It is configured to feed the accommodated seedlings (1) toward the corresponding planting device (3) in the direction of inclination at the lower rear side.The connecting rod (
13 has a hydraulic lifting mechanism (
m is provided, and the seedling planting device (4) can be raised and lowered by means of this raising and lowering mechanism (1) using an operating lever near the cockpit seat 0.

The supply seedling platform (6) is equipped with a column (Ill (+9)) with a four-point linkage mechanism that is rotatable in the front and rear directions at the rear of the traveling vehicle body (5).
and are provided so as to face and match the left and right horizontal movement stopping posture at the left and right center position of each seedling tank (2).

The supplementary seedlings (1) are placed on the upper surface of each supplementary seedling support plate (6).
It has a structure that allows it to be placed together with the prop (Ill), and there is a hydraulic seedling platform moving device between it and the traveling vehicle body (5).
7), and as shown in Figures 1, 4, and 5, there is a switch (SWI) that detects the forward and backward rotational position of this support post +11.
, (SW2) and solenoid (SOLI), (SQL2
), the hydraulic telescopic cylinder mechanism Q3 can be moved forward (d) and rearward (e). A seedling sensor (SW3) that detects the presence or absence of supplementary seedlings (1) is provided in this circuit for each supplementary seedling mounting table (6), and the all-seedling sensor (SW3) detects the placement of supplementary seedlings (1). When the condition is reached, the solenoid (SOLI) operates to contract the telescopic cylinder mechanism Q3 and release the seedling table (6).
These seedling sensors (S
When detecting that there are no supplemented seedlings (1) on the supplementary seedling platform (6) in any of W3), the solenoid (S
OL 2) is activated to extend the telescopic cylinder mechanism (2δ and move the supply seedling platform T6) to the rear (E). (SW4) is an automatic changeover switch, which is installed near the control handle (111) and is operated when the circuit of the supply seedling platform (6) is activated.Switch (swl), (SW2
) turns off the circuit when pushed by the pillar (Ill).

Seedlings +11 raised in a seedling box with a bed in a planar shape are accommodated in the upper surface of each seedling tank (2) and each supplementary seedling platform (6), and seedling planting work is performed. The operator turns on the automatic changeover switch (SW4) in advance to enable the seedling table moving device (7) to work, then leaves the cockpit (lδ) and goes to the rear side of the seedling planting device (4) to raise the seedlings. While scooping up the seedlings (1) grown in the box with the seedling receiving plate, the seedling planting device (

SW3) detects the supplied seedling (1), so the solenoid (
SOLI) works to contract the telescopic cylinder mechanism QX5 and move it in the forward (d) direction.

During seedling planting, the seedlings (1) in the seedling tank (2) are placed in the planting device (3).
), once the seedlings have been transplanted and decreased in number, stop planting the seedlings at an appropriate position, turn off the automatic changeover switch (SW4), and place the supplementary seedlings (1) on the supplementary seedling tray (6) on the seedling receiving plate 4. Take out the seedlings and insert them into the rear seedling tank (2).

In this case, if the seedling planting device (4) is placed in the raised position by the lifting mechanism (1η), the upper end of the seedling tank (2) will be close to the supply seedling platform (6) on the front side. It is easy to supply seedlings (1) from the side.When supplying seedlings (1) from the seedling stand (6) to the seedling tank (2), press the automatic changeover switch (SW4) as described above. By keeping it OFF, even if one of the seedling trays (6) is taken out and becomes empty, the seedling tray (6) is immediately moved to the rear. Never.

In addition, when using the seedling receiving plate (2G), each seedling sensor (S
W3) cannot supply seedlings (1) by simply placing this seedling receiving plate QO.
For example, a detection form such as a weight sensor is used, which cannot detect the presence of the supplementary seedling (1) and can detect the presence of the supplementary seedling (1) when placed together with the supplementary seedling (1).
