Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling feeding method for a seedling machine which can automatically and continuously feed seedlings such as sweet potato to the seedling machine.

[0002]

2. Description of the Related Art Conventionally, as a method of supplying seedlings to a seedling machine for seedlings having a tendency to be entangled, such as sweet potato, an operator manually puts one seedling in accordance with the moving speed of the seedling machine. It is being supplied, for example, the one in which the operator holds the seedlings in the seedling holder is disclosed in JP-A-4-36108, and the operator supplies the seedlings to the seedling supplying area of the transplanter. Those are disclosed in JP-A-4-148607.

[0003]

[Problems to be Solved by the Invention] The above-mentioned prior art
In the seedling inserting machine (transplanting machine), since the seedlings are supplied by the workers, it was impossible to improve the work efficiency to a certain level or more. In general, seedling work is performed during the daytime on sunny days such as in the evening or during rainy days in order to ensure the survival and growth of seedlings after seedling. Therefore, it was necessary to improve the working efficiency of the seedling machine. . In addition, in the conventional seedling machine, the operator supplies the seedlings while manipulating the machine, so that the operator is physically and mentally burdened. The present invention has been made for the purpose of solving the above problems.

[0004]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides (1) a seedling feeding method for feeding a seedling having a property of easily entwining like sweet potato to a seedling machine, wherein the base of the seedling is roped. , Tapes, etc. are held at a predetermined interval and hung so that the growth point side is downwards, and are supplied to the seedling machine, and seedlings, ropes, tapes, etc. are cut by the seedling machine or the seedlings are released and seedlings are cut. (2) The base of the seedling is continuously held on a rope, tape, etc. at a predetermined interval, and the rope, tape, etc. holding this seedling are wound in a cylindrical shape to form a seedling feeding unit, The present invention is characterized in that the seedling feeding unit is supplied to a seedling seeding machine so that seedlings are held while rewinding ropes, tapes and the like holding seedlings.

[0005]

According to the seedling feeding method of the present invention by the above-mentioned means, since the base of the seedling is hung so that the growth point side is on the lower side, the angle and spread of the petiole with respect to the stem are reduced. The area occupied by one seedling is reduced, and the entanglement of seedlings is reduced. Therefore, when one seedling is taken out to the seedling mechanism of the seedling machine, it can be easily taken out even if its petiole is slightly entangled with other seedlings, and the posture of the remaining seedlings is disturbed. When the entanglement disappears, the growing point returns to a posture in which the growing point always faces downward due to its own weight, and the seedlings are continuously supplied with seedlings. Therefore, automatic supply becomes possible, and the work efficiency can be improved by speeding up the seedling work and increasing the number of threads.

Then, the rope collecting drum 26 and the seedling winding drum 13 are configured to rotate in association with each other. As described above, the rotational moving speed of the seedling winding drum 13 and the winding speed of the rope collecting drum 26 are set. Are synchronized. Although not shown, the rotational speeds of the rope collecting drum 26 and the seedling winding drum 13 and the rotating operation of the seedling claw 28 are synchronized and intermittently performed.

FIG. 8 shows a seedling machine equipped with the seedling feeding device shown in FIGS. 6 and 7. This seedling inserting machine is of a walking type, and an engine 36 is mounted on the front part of the machine body, and drive wheels 38 are driven by its power. A front wheel 37 that also functions as a ridge running guide is provided in front of the drive wheel 38, and the front wheel 37 and the drive wheel 38 drive the ridge. The seedling winding drum 13 (seed feeding unit) is set in front of the handle 39 for driving operation, and the belt 35, the pulley 34, the rotary shaft 33 (the friction wheel 3 are driven by the power from the engine 36.
Rotated via 2). The seedling-growing claw 28 moves up and down by the power of the engine via the crank mechanism to plant the sweet potato seedlings 3 in the ridge 40.

Although a walk-type seedling machine has been described in the above embodiment, it may be a riding type, or may be a multi-row type as well as a single-line type. In addition, the base of the seedling 3 is cut off from the rope 4 (seed band) in which the seedling 3 is braided by the cutting blade 29 attached to the nail 28 for seedling, and the seedling 3 is planted in the field by the nail 28 for seedling. However, it is also possible to cut the rope, tape or the like or release the holding of the seedlings for seedling insertion.

[0016]

As described above, since the seedling feeding method for the seedling machine according to the present invention has the above-mentioned means, the following effects can be obtained. According to the seedling feeding method of the present invention, it becomes possible to continuously perform seedling work in a field in a seedling machine, and since the seedling supply speed is not affected by human work efficiency, two or more pairs of seedling supply devices and seedling nails are mounted. By doing so, it becomes possible to increase the number of rows and the planting efficiency is improved proportionally.

Further, by suspending the sweet potato seedlings, since the position of the seedling base portion held by the seedling nails does not move, the seedlings can be held reliably and seedling planting accuracy can be improved. Furthermore, handling of seedlings and setting of seedlings in the seedling machine become easy, and it becomes possible to control seedling nails and seedling supply.
