Description

[Detailed description of the invention] The present invention relates to a seedling planting device that divides and plants seedlings for planting stocks from pine seedlings on a seedling platform in a multi-row rice transplanter using pine seedlings. It is something.

A rice transplanter for multi-row planting using pine seedlings for four or more rows is equipped with a seedling dividing and planting moving body for each planting row installed in parallel on the seedling take-out side of the seedling stand, and these multiple seedling dividing planting machines The moving bodies are interlocked via a transmission mechanism, and the moving body in the center of the body receives power from the drive side, so that all the seedling dividing and planting moving bodies simultaneously perform seedling dividing and planting movements. There is.

By the way, each of the seedling dividing and planting moving bodies of the rice transplanter described above receives power directly from the driving side, whereas the one inside the machine (center part) receives power directly from the drive side, and the one on the outside of the machine receives power through more transmission mechanisms. Therefore, the seedling splitting and planting movement body outside the machine tends to cause irregularities and vibrations, which reduces the ability to hold the split seedlings while transporting them to the planting position, resulting in many dropped seedlings. The reality is that seedling planting performance is not necessarily good.

In view of the above-mentioned circumstances, the present invention was devised in order to eliminate the inconvenience, and its purpose is to reduce the splitting seedling holding force of the plural seedling splitting and planting movement bodies to the inside of the machine. By making the outer part larger, both the seedling dividing and planting movement body located inside the machine body (center) and the seedling division planting movement body located outside the machine body can be divided appropriately and evenly. It is an object of the present invention to provide a seedling planting device for a rice transplanter that can maintain seedling retention power, eliminate the occurrence of dropped seedlings, and significantly improve planting performance.

To explain the structure of the present invention with reference to an embodiment shown in the drawing, the figure shows a rice transplanter for planting in four rows, and 1 is a seedling loading stand, and this seedling loading stand 1 is used for each planting row. Seedling mounting parts 1a, 1a, on which pine seedlings are placed.
1b, 1b. A seedling receiver 2 is installed opposite to the seedling take-out side of the seedling tray 1, and this seedling receiver 2
Seedling take-out ports 2a, 2a, 2b, 2b are formed corresponding to the seedling trays 1a, 1a, 1b, 1b. Reference numeral 3 denotes a seedling planting device for four-row planting, and this seedling planting device 3 is connected to each seedling mounting section 1a, 1 of the seedling mounting table 1.
Seedling division planting movement body 3 corresponding to a, 1b, 1b
a, 3a, 3b, 3b, and the base end sides of these seedling division planting movement bodies 3a, 3a are pivotally connected to cranks 4a, 4a and movement regulating arms 5a, 5a, and the seedling division planting movement bodies 3a, 3a are The base end sides of the moving bodies 3b, 3b are connected to cranks 4b, 4b and a movement regulating arm 5.
It is pivotally connected to b and 5b. A pair of seedling dividing claws 6a, 6a are attached to the tip sides of the seedling dividing and planting movement bodies 3a, 3a, respectively.
A seedling planting extrusion body 7a is provided between a and 6a. Similar seedling dividing claws 6b, 6b and seedling planting extrusion body 7b are also provided on the tip sides of the other seedling dividing and planting movement bodies 3b, 3b, respectively. For the distance l between the tips of the seedling dividing claws 6a, 6a and the end face of the seedling planting extrusion body 7a at the seedling division position, the distance l between the seedling division claws 6b, 6b and the end face of the seedling planting extrusion body 7b at the same position. By increasing the distance l′ and inserting the seedlings deeper between the seedling splitting claws, the splitting seedling holding force of the seedling splitting and planting motion bodies 3a, 3a located inside (center) of the machine body is increased, and the seedlings are placed on the outside of the machine body. It is set so that the divided seedling holding force of the located seedling dividing and planting movement bodies 3b, 3b is large. In addition, the seedling division planting movement body 3 inside the fuselage
Seedling division planting movement body 3b on the outside with respect to a, 3a,
Another means for increasing the divided seedling holding power of 3b is to use the seedling dividing claws 6b, 6 rather than the seedling dividing claws 6a, 6a.
It is also possible to make the width of the claws b larger and the seedling holding surface larger.

Reference numeral 8 denotes a transmission shaft of the seedling planting device 3, and the center portion of the transmission shaft 8 is linked to the drive side by a transmission chain 9, and is linked to the cranks 4a, 4a by a transmission chain 10. has been done. Further, both ends of the transmission shaft 8 are interlocked with cranks 4b, 4b via transmission chains 11, 11.

In addition, 12, 12 is a body propulsion wheel, 13 is a float, 14 is an engine, and 15 is a control handle.

In the present invention configured as described above, the seedling dividing and planting moving bodies 3a, 3a of the seedling planting device 3 receive power transmitted from the drive side to the transmission shaft 8, and the crank 4
The tips of the seedling dividing claws 6a, 6a move up and down in a constant trajectory by the operation of the seedling dividing claws 6a, 4a, and the other seedling dividing/planting movement bodies 3b, 3b are also moved by the cranks 4b, 4a.
4b causes the seedling dividing claws 6b, 6b to similarly move up and down. And each of these seedling dividing nails 6
By a, 6a, 6b, and 6b, the pine seedlings for planting stocks are divided from the pine seedlings on the seedling trays 1a, 1a, 1b, and 1b on the seedling platform 1, and the seedlings are held and transported to the planting position. It is discovered and planted. By the way, in the present invention, the seedling dividing and planting movement bodies 3b, 3b located on the outside of the machine body have a splitting seedling holding force in contrast to the seedling dividing and planting movement bodies 3a, 3a located on the inside (center) of the machine body.
Since the divided seedling holding force of 3 is made large, even if malfunction occurs in the seedling dividing and planting movement bodies 3b, which are driven through more transmission mechanisms than the seedling dividing and planting movement bodies 3a, 3a, or The holding power of the divided seedlings is maintained at an appropriate level even under vibrations, etc., and it is possible to prevent the occurrence of dropped seedlings.

In short, the present invention provides a plurality of seedling division planting moving bodies corresponding to each of the seedling trays on the seedling take-out side of a seedling tray having a plurality of seedling trays, and a plurality of seedling division planting moving bodies are provided on the seedling take-out side of a seedling tray having a plurality of seedling trays. Since the attachment moving body is configured so that the splitting seedling holding force on the outside is larger than that on the inside of the machine, the seedling splitting and planting moving body located inside the machine also has a larger holding force on the outside of the machine. The seedling splitting and planting moving body located at the same position can also maintain a moderately even splitting seedling holding force, which is extremely useful and practical as it can eliminate the occurrence of dropped seedlings and improve planting performance. It is effective.
