Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for extruding seedlings at a transplanting part in a transplanter for relatively hard seedlings such as rush seedlings.

[0002]

2. Description of the Related Art As one of the conventional methods for transplanting rush seedlings, planted seedlings divided for each plant are sent to a lower part of a seedling nest and grasped from the left and right with a fork-shaped beak. What is planted in is known.

[0003]

However, in the above-described conventional mechanism, if all the seedlings are to be surely grasped in accordance with the variation in the diameter of the planted seedlings, etc., the grasp becomes hard in a thick seedling. When planting seedlings, the seedlings are not well separated from the beak,
If the beak tip is too wide in order to improve the detachment of the seedling, the seedling will fall after grasping, or the beak mark at the time of planting will be too large and the seedling will fall over after planting Or there was a problem such as floating. The present invention is intended to solve the above problems.

[0004]

According to the mechanism of the present invention for solving the above-mentioned problems, a planted seedling 25a fed to a seedling feeding side of a seedling nest 21 is held between a pair of beaks 14a and 14b. In the mechanism for lowering and transplanting the seedlings from the seedling stand to the field scene side, an extruding tool 28 made of a flexible member is provided along the root of the planted seedlings 25a on the leading end of the beak between the beaks 14a and 14b. And the extruding tool 28 is configured to receive the earth pressure from the back side as the beaks 14a and 14b enter the field scene 24 side and bend the planted seedling 25a in the pushing direction. .

[0005]

A pair of beaks 14a and 14b hold the planted seedling 25a fed to the seedling feeding side of the seedling rest 21 by closing the tip from an open state to a closed state, thereby holding the seedling rest 21 from the seedling stand 21 to the field scene 24 side. The seedling 25a is transplanted by pushing it into the field scene 24 and opening it. Beak 14
At the moment when the planting seedling 25a is opened from between the a and 14b, the extruding tool 2 which has been on the back side of the beaks 14a and 14b until then.
8 bends to the front side of the beaks 14a and 14b due to the earth pressure in the field scene accompanying the beak lowering insertion, and the beaks 14a and 14b are bent.
b, the planted seedling 25a is pushed forward and the beak 14a,
The seedlings are separated from 14b. After implantation, the pusher 28 is restored to its original position by its elasticity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 4 is an overall side view of a riding transplanter, in which seats 2, 3 on which an operator and a seedling replenisher are seated are installed on a body 1 of the present invention. At the rear, a planting machine 7 to which a PTO shaft 6 is connected is connected by a lifting link 4.

The working machine 7 is floated and grounded by a float 8, and the tip of a planter arm 11 rotatably attached to both rear ends of a plurality of planter cases 9 via covers 12, 13 which also serve as beak holders. The base ends of the pair of fork-shaped beaks 14a and 14b are shafts (bolts) 1
The insertion shaft is supported by 6a and 16b.

The beaks 14a and 14b have covers 12, 1
The levers 17a, 17b extending in a "U" shape extend so as to intersect with each other within the lever 3, and the levers 17a, 17b are extended.
One end of a link 18 is connected to the inner end of each, and the other end of the link 18 is pivotally connected to each other by a pin 19. The pin 19 is driven up and down during the rotation of the planter arm 11. The beaks 14a and 14b have a mechanism for opening and closing pivotally.

The tips of the beaks 14a and 14b rotate so as to form a trajectory Q, are fixedly fed from above the seedling mount 21, and are intermittently cut off by the cutter 23 from the left and right. Is released in a timely manner near the bottom dead center of the trajectory Q, and is planted in the field scene 24.

A U-shaped receiving guide 26 is provided on the lower end of the seedling stand 21 for receiving and supporting the stem portion of the planted seedling 25a to be cut.
On one side of b, a rod-shaped holder 27 for temporarily receiving the vicinity of the root of the planted seedling 25a after cutting is fixed in the left-right direction.

On the cover 12, the base end has a "T" shape, and the strip-shaped front end has beaks 14a, 14a.
A pusher 28 extending between the base ends of b and along the back side of the beaks 14a, 14b and formed of a leaf spring having a "-" shape in a side view is attached by bolts 16a, 16b.

When the tip of the beaker is in the air, the tip of the pusher 28 is substantially parallel to the rear side of the beaks 14a and 14b as shown by the solid line in FIGS. As shown by the imaginary line in the figure, when the tip is inserted into the mud from the field scene 24 (the beak tip is open at this time), the tip receives the mud pressure in the field, and the beak 14a,
As a result of being pushed between the beaks 14a and 14b, the planted seedlings 25a inside are pushed forward as the beaks 14a and 14b retreat and ascend, and the seedlings are securely separated from the beaks 14a and 14b. When the beaks 14a and 14b are pulled out to the ground, the tip of the pusher 28 returns to the state shown by the solid line again due to its elasticity.

FIG. 3 shows a state of the band-shaped seedling 25 before cutting.
The hair root and stem culm at the lower end (which is strictly a leaf) are
In addition to connecting the seedlings that have been flattened and pressed to the front and back of the tape in a strip shape, the base of the stock is covered and connected with a tape 31 from the front and back, and a thread 32 is spirally wound around the tape 31 to form an integral body. Which formed a strip-shaped seedling 25,
On the planting machine 7, the stocker 33 is wound in a roll shape.
And is quantitatively sent while the ends thereof are sequentially erected in the vertical direction on the seedling placing table 21.

The band-shaped seedling 25 and the tape 31 may be made of natural fiber such as paper which is decomposed in the soil. For example, high molecular polysaccharides similar to starch contained in plants and microorganisms are converted from natural polymers. You may use biodegradable plastic, which is a plastic sheet made by chemically bonding the extracted material. If the tape is made in this way, it will be decomposed by soil microorganisms (bacilli) in the soil, leaving only pollutants. In addition, there is an advantage that the planting seedling is naturally mixed with fertilizer to promote survival and does not affect the ecosystem.

[0015]

According to the mechanism of the present invention configured as described above, when the beak is raised and lowered and moved back and forth, the seedling on the seedling nest side is held in a closed state and planted in a field scene. The detachment of the seedling from the beak with only a slight opening of the beak, or with almost no opening operation, is performed by the pushing action of the pushing tool.

As a result, it is possible to solve the problems such as the rotation of the planted seedlings caused by not opening the beak, the dropping of the planted seedlings due to the excessive opening of the beak, the excessive size of the planting holes, the floating of the seedlings, and the falling of the seedlings. There is.

[0017] The seedling pushing action of the extruder uses the earth pressure as a reaction accompanying the lowering of the beak at the time of planting, so that power for operating the extruder and a special drive mechanism are not required, and the mechanism is simple. And low cost.
