Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention, for example, uses a plurality of block-shaped seedlings, which are held on two continuous tapes at predetermined intervals in the longitudinal direction of the tapes, as tape seedlings. The present invention relates to a tape seedling transplanting machine for planting things that are stacked and stored in a zigzag shape.

[Conventional technology]

Conventional tape seedling transplanters include, for example, Japanese Patent Application No. 63-15.
Applicants have proposed such as shown in 1440. The gist of this is, as shown in FIG. 1 of Japanese Patent Application No. 63-151440, unwind a tape seedling that has been wound into a spiral shape, separate the two continuous tapes at a predetermined position, and separate them. Aim at the place where the block-shaped seedlings are in the open posture, scrape with a scraping claw to peel off, and drop the peeled block-shaped seedlings to the planting site by the guide of the planting guide part. there were.

[Problems to be Solved by the Invention]

That is, in the above-mentioned conventional technique, it is necessary to once wind the continuous tape holding the block-shaped seedlings in a spiral shape with a winding roll in the process of preparing the tape seedlings before planting. However, considering the case of winding tape seedlings on a take-up roll, the block-shaped seedlings held on the continuous tape show that the plant origin is in one of the axial directions of the take-up roll and the stem tip is in the other. The diameter of the tape seedling is larger than that of the tip of the stem because the diameter is larger than the tip of the stem. Therefore, the larger the winding amount of the tape seedlings, the larger the difference in the winding diameter becomes. Therefore, when the winding amount of the tape seedlings is increased, it is easy to cause a problem that the winding state is collapsed during the winding operation of the tape seedlings or the transportation of the tape seedlings wound on the winding roll.
If the winding amount is reduced in order to prevent the winding state from collapsing, there is a disadvantage that the seedlings must be frequently supplied during the seedling planting work. Further, when the tape seedlings are wound up, the pressure becomes stronger toward the central portion side, so that the block-shaped seedlings closer to the central portion are more easily damaged.

In addition, since the continuous tape is separated and the block-shaped seedlings are peeled off from the continuous tape with a scraping body, the scraping method is adopted, so when separating the continuous tape, the adhesive force with the continuous tape pulls the block-shaped seedlings. As the seedling's posture was disturbed, the scraped body forcedly peeled the block-shaped seedling from the continuous tape, sometimes damaging the block-shaped seedling.

An object of the present invention is to provide a seedling storage unit that can store and transport tape seedlings well, and efficiently plant a block-shaped seedling held on a continuous tape fed from this seedling storage unit without disturbing the posture. It is about providing what you can.

[Means for Solving the Problems]

A characteristic configuration of the tape seedling transplanter according to the present invention is a continuous tape in which a plurality of block-shaped seedlings, each of which has been stocked, are held side by side along the tape longitudinal direction at predetermined intervals,
In a state in which the block-shaped seedlings are in a sideways posture, a seedling storage portion that is stacked and stored in a zigzag shape, a transport device that transports the block-shaped seedlings held by the continuous tape, and the transport device that transports the block-shaped seedlings. A cutting mechanism for cutting the tape-shaped seedlings while keeping the tape-shaped seedlings on the tape and separating the seedlings into block-shaped seedlings for each strain is provided on the frame side of the machine, and the block-shaped seedlings separated by the cutting mechanism are provided. The point is that a holding mechanism and a planting claw for taking out and planting the block-shaped seedlings held by the holding mechanism are provided.

[Action]

According to the present invention, the tape seedling has a zigzag shape in a state where the block-shaped seedlings held on the continuous tape are in a horizontal posture (the tape seedlings are folded so that the portion to be stored next is overlapped on the portion previously stored). Will be stored in the seedling storage section.

Therefore, since the plant base of the block-shaped seedling has a larger diameter than the tip of the stem, even if the tape seedlings are stored in this seedling storage unit, the plant base side will have a high tilted posture. Unlike in the case of winding tape seedlings on a take-up roll as in the case of the prior art, since the tape seedlings are simply stacked in a folded shape in the seedling storage part, the root part and the tip of the stem part The stacked state does not collapse due to the difference in diameter. In addition, since the stacked state of the tape seedlings is only placed on the upper part which is stored next to the lower part which is stored first, the tape seedlings are stacked as the number of stacking stages increases. Since the block-shaped seedlings held by the upper continuous tape will enter between the adjacent block-shaped seedlings held by the lower continuous tape by its own weight, the degree of inclination in the stacked state becomes small, The whole stacking posture is stable. In other words, while increasing the amount of tape seedlings stored in the seedling storage unit to reduce the number of seedling replenishment operations during seedling planting work, tape for storing tape seedlings in the seedling storage unit and for transporting the stored tape seedlings You can avoid collapse of seedlings.

In addition, as you do not need to wind the tape seedling strongly to prevent the winding state from collapsing, as when winding the tape seedling in a spiral shape with a winding roll, you can In comparison, the pressure on the block seedlings is weakened. Therefore, it is possible to reduce the inconvenience that the block-shaped seedlings are damaged by pressure.

On the other hand, when planting tape seedlings, the tape seedlings stored in the seedling storage unit are transported from the seedling storage unit by the transport device, the transport start end side is held by the holding mechanism, and the tape is transported in a continuous state in the holding state. The seedlings on the starting end side are cut by a cutting mechanism, and the succeeding tape seedlings are separated into one block of seedlings with continuous tape attached. The separated block-shaped seedlings for one strain are continuously held by the holding mechanism, removed from the holding mechanism by the planting claws, and planted.

In other words, the holding mechanism can hold the tape seedlings in a predetermined posture that can be easily cut by the cutting mechanism, and the block seedlings can be held in a predetermined posture that is easily removed from the holding mechanism by the planting claws, so that good cutting and planting can be performed. become. Moreover, since the cutting portion by the cutting mechanism is also the continuous tape portion, it does not directly act on the block-shaped seedlings, so that the block-shaped seedlings are not damaged.

〔The invention's effect〕

Therefore, by providing the seedling storage section, even if the tape seedling is made relatively long, it becomes possible to easily store and transport the tape seedling,
It is possible to reduce the number of times of seedling replenishment during seedling planting work and improve work efficiency.

In addition, the block-shaped seedlings attached to the continuous tape are not peeled off by force against the adhesive force, and the seedlings are held by the planting nails so that the seedlings are held even when planting with the planting nails. Since it can be detached from the holding mechanism and planted, the disturbance of the posture of the block-shaped seedling and the damage phenomenon to the block-shaped seedling can be suppressed.

Therefore, it became possible to avoid the floating seedling phenomenon on the planting surface and the poor growth due to damage of the seedlings.

However, it is conceivable that the cutting mechanism is formed integrally with the planting claw as the planting claw is separated from each plant while being held on the tape and planted by the planting claw in this case. Since the cutting mechanism also rotates to the vicinity of the planting surface with the operation of planting the claws, mud may stick up when the planting claws plunge into the mud, and the tape cutting performance deteriorates. However, in the case of the present invention, since the cutting mechanism is provided on the machine side, there is no influence of mud and the cutting mechanism can be provided at any position on the machine side, so installation There are few restrictions.
