Description

[Detailed explanation of the invention] When planting seedlings for horticulture such as leaf tobacco and cabbage using planting claws that move up and down at a constant swing width in a ridge with an arc-shaped cross section, the height of one ridge is If the seedlings were uneven and undulating, conventionally the seedlings would have to be planted deeply in high places and shallowly in shallow places, which had the disadvantage that the seedlings would not grow evenly.

The present invention aims to improve this drawback. Reference numeral 1 denotes a pair of left and right connecting rods whose tips are connected to both sides of the machine wall 2, and a cutting plate 3 in the middle that contacts the top of the ridge.
While fixing it across the left and right connecting rods 1 and 1,
As shown in FIG. 2, a pair of conical rollers 5, 5 having slightly arcuate sides are rotatably attached to the shaft rod 4 installed at the end thereof.

Reference numeral 6 denotes an extendable hanging rod with a turnbuckle 6a attached to its middle part, and its lower end passes through the middle part of the shaft rod 4 as shown in FIG. 2, and its upper end is connected to a seedling stand 7 connected to the machine wall 2. .

Reference numeral 8 denotes a crank installed in the fuselage A that is driven by the engine E installed in the fuselage A, and is attached to the ends of the upper and lower parallel links 9, 9 via a transmission mechanism in the machine wall 2 that is pivotally attached to the fuselage A so that it can swing freely. The planted nails 10 are raised and lowered with a constant swing width. a indicates the axis attachment point of the aircraft wall 2 to the aircraft body A.

Reference numeral 11 denotes a plurality of pots arranged along a ring provided on the seedling platform 7, and when seedlings with soil are supplied inside, they move sequentially along the ring (not shown), and when the planting claw 10 rises to the highest position, Open the bottom of pot 11 and supply seedlings. Then, the planting claw 10 descends and plunges into the ground between the earth cutting board 3 and the conical roller 5, and when it reaches the lowest position, it opens back and forth to plant the seedlings, and then rises while remaining open and reaches the highest position. Closes just before reaching the end.

In the present invention, if the height of one ridge is uneven, for example if it is too high, the pair of conical rollers 5, 5 at the ends of the pair of left and right connecting rods 1, 1 connected to the machine wall 2 are Since the seedling stand 7, parallel links 9, 9, and the planting claw 10 rise together with the pivot point a of the wall 2 to the machine base A as a fulcrum, the planting claw 10 moves up and down with a constant swing width. The degree of penetration into the ground remains unchanged.

If the height is too low, the pair of conical rollers 5, 5 will descend together with the planting claws 10, etc., using the pivot point a as a fulcrum, as described above, so that the planting claws 10 will not reach the ground. The degree of penetration remains unchanged.

In this way, according to the present invention, the conical roller 5 connected to the machine wall 2 rises or descends depending on the height of the ridge, and the machine wall 2 is moved around the pivot point a of the machine wall 2 to the machine body A as a fulcrum.
The positions of the seedling stand 7 and the planting claw 10, which are the same body, become higher or lower. This produces the effect that seedlings can be planted at a deep depth.
