Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seedling supply device for a seedling transplanter. In order to carry out the seedling planting work efficiently without interruption, it is necessary to place supplementary seedlings on the seedling transplanter and ensure that these supplementary seedlings are transferred smoothly to the bacteria tank. Due to the undulations of the soil or variations in soil tillage, etc., there is a difference in level between the replenishing seedling platform and the seedling tank, making it difficult to replenish seedlings smoothly.

The present invention takes the following technical measures in order to eliminate such problems. That is, the seedling tank (2) is refilled in correspondence with the upper end (3) of the seedling tank (2), which is attached to the traveling body (9) so as to be movable up and down and is acted upon by the seedling device (1). A supplementary seedling holder (
5) is provided on the traveling body (9), and this supply seedling holder (5)
At the tip of the seedling tank (2), it is possible to raise the seedling tank (2) by pushing it up ((a) and transfer the supplied seedlings (4) from the supplied seedling holder (5) to this seedling tank (2). A seedling supply device for a seedling planting machine is configured with a succession shelf (6).

This invention has the following technical effects due to such a configuration. That is, seedling planting work is carried out by supplying seedlings (4) in advance onto the seedling tank (2) and the supply seedling holder (5), and moving the traveling machine (9) to move the seedling cutting device (1). Seedlings are separated from the lower end of the seedling tank (2) by seedling movement.
Plant the seedlings (4) in this seedling tank (2) by planting them on the soil surface.
When the number of seedlings decreases, the seedlings (4) on the supply seedling holder (5) are supplied to the seedling tank (2) via the inheritance shelf (6) and continuous seedling work is performed, but the supply on the traveling machine (9) side The position of the seedling holder (5) in relation to the seedling tank (2) on the seedling device (1) side may vary depending on the conditions of the planting field, such as the unevenness of the planting soil surface or the unevenness of the soil tiller. Tank (2) and this seedling tank (2)
Supply seedling holder (5) provided corresponding to the upper end (3) of the
Although there is a step between the

) is located below the supply seedling holder (5), it is easy to replenish the seedlings (4) to the seedling tank (2), and the seedling tank (
The inheritance shelf (6) that can be pushed up even if the seedling tank (2) is positioned higher than the seedling tank (2) due to the raising of the seedling tank (2) ((a)) ensures that the seedling (4) is inherited accurately and is easy to use during seedling planting work. Replenishment of seedlings can be easily and smoothly carried out regardless of the vertical movement of the seedling tank (2).

In the illustrated example, the riding rice transplanter (7) has front wheels and rear wheels (8
) (8), and a seedling cutting device (1), a seedling tank (2), a float 00, etc. connected to the rear of this body (9). Aircraft (9)
is equipped with an engine in the front, and the power of this engine is linked to the change mission case 01) installed in the middle lower part of the fuselage (9), and the left and right rear wheel drive shaft a at the rear of the fuselage (9). The front and rear wheels (8) (8
), and is also configured to be transmitted to the seedling device (1) and seedling tank (2) via the power take-off shaft. The seedling tank (2) is located behind the rear wheels (8) (8), is capable of reciprocating in the left and right direction, and has a raised wall 0η0η that divides the seedling resting surface 0Q into six parts in the left and right direction. , and the upper end (
3) is inclined toward the front and upward. This seedling tank (
The seedling device (1) (1) is configured to move up and down in response to the lower end of the slope of 2), and a float αO is provided below it, and these seedling planting devices are connected at three points relative to the traveling device (9). The seedling inserting device (1) is connected to a pitch link mechanism (04), and the seedling planting device (1) is configured to be able to be raised and lowered and detached via this hitch link mechanism Q4, and is also provided so that it can be raised and lowered with respect to the body (9) by a hydraulic mechanism a barrel. ing. Also, this hydraulic mechanism θ frame has a float of 0.
By detecting the inclination angle of 1, this float 00 surface should be expanded and contracted so that it slides horizontally with respect to the soil surface. It is configured in a linked manner. The supply seedling holder (5) is attached to the rear wheel (8) (
8) above the replenishment tank (2) corresponding to the upper end (3) of the seedling tank (2), and is supported by a frame QGQυ... (5) Seedling tank (
It has a partition wall (E) for partitioning the seedling receiving surface 01 into six left and right sections facing the seedling placing surface QQ of 2), and is provided on both left and right sides of the replenishing seedling holder (5). A support plate QηQυ is provided at the end, and the inheritance shelf (6) is pivoted between the support plates QυQυ so that it can freely move downwards, and the transfer shelf (6) is mounted from approximately the center of each partitioned seedling receiving surface. It is provided so as to bridge over the upper end (3) of the seedling tank (2). Note that the transfer shelf (6) may be made to protrude and retract in the front-rear direction (or may be biased downward by a spring or the like).

Reference numeral (2) denotes a seat, which is disposed in front of the supplementary seedling holder (5) at the middle of the left and right sides. (Incorporated) is a seedling scooping board, which can also be supplied to the seedling receiving surface θ1 of the supplementary seedling pedestal (5) with supplementary seedlings (4) placed on the upper surface.

The seedling tank (2) and the supply seedling pedestal (5) are supplied with square mat-shaped seedlings (4), and the traveling machine (9) is advanced to move the seedling cutting device (1) up and down. The seedlings (4) at the lower end of the seedling tank (2) are separated and planted on the soil surface. In conjunction with this seedling movement, the seedling tank (2) repeatedly moves back and forth in the left and right direction, and the seedling planting work is performed.
When the number of seedlings (4) in the seedling tank (2) decreases, a bridge is formed between the replenishing seedling holder (5) and the upper end (3) of the seedling tank (2) so that the seedlings can move up and down. The replenishment seedlings (4) are supplied by sliding on the inheritance shelf (6), thereby performing continuous seeding work.

In this seedling work, I+
If the soil surface is open due to unevenness of the board, etc., float α
4 is detected by the hydraulic mechanism 0→, and the float 0 slides horizontally on the wharf surface with respect to the soil surface.

This causes a vertical step between the upper end (3) of the seedling tank (2) and the supplementary seedling pedestal (5), but the inheritance shelf (6) is located at the upper end of the seedling tank (2). Sliding contact with part (3) [2
Because the seedling tank (2) rotates with
