Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seedling platform structure for tape-shaped seedlings for transplanting seedlings such as strawberries in a field using the tape-shaped seedlings.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, when the seedling tape-shaped seedlings are placed on a seedling placing table and sent out to the seedlings scraping means side to be guided, the seedling scraping means have a standing posture. When scraping the planted seedlings, the tape-shaped seedlings were also placed so that the planted seedlings were in an upright posture.
In this case, the tape-shaped seedlings must maintain the standing posture from the upper side of the feeding direction to the seedling scraping means, but the tape-shaped seedlings are those in which the planted seedlings are arranged in a predetermined pitch. Since the seedlings are not densely packed like the pine-like seedlings, they easily fall down due to a slight vibration of the body, which causes a problem that the scraping posture is disturbed and it becomes impossible to plant seedlings with high accuracy.

[Means for Solving Problems] In view of the above-mentioned circumstances, the present invention was devised with the object of providing a seedling table structure for tape-shaped planting seedlings that can eliminate these drawbacks. , A seedling placing table for guiding the seedling scraping means side for placing the tape-shaped seedlings, which are adhered by arranging the planted seedlings on the tape, and scraping the seedlings planted upright, A seedling storage section for accommodating the planted seedlings of the tape-shaped seedlings in a lying posture is provided on the upper side of the seedling placing table in the seedling feeding direction, and between the seedling placing section and the seedling scraping section of the seedling placing table. The present invention is characterized in that an erecting guide means is provided for gradually changing the planted seedlings in the lying posture, which are fed out from the seedling accommodation section, into the standing posture.

With this configuration, the present invention guides the tape-shaped seedlings to scrape off the planted seedlings in the standing posture, while eliminating the disturbance of the posture of the tape-shaped seedlings during the feeding. It was done.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a riding type mobile body for traveling in a paddy field, and a transplant portion 2 in which the present invention is implemented behind the mobile body 1.
Is mounted so that it can move up and down. This transplant part 2
Is a six-row plant, but three sets of gear cases 3 extending rearward from the transplant part frame are provided with planting claws 4 on both left and right sides. On the other hand, a seedling mounting table 5 is provided on the transplanting part frame, and a winding drum 7 around which a tape-shaped seedling 10 described later is wound is rotatably supported at the upper end of the seedling mounting table 5. Has been done. In other words, above the seedling mounting table 5,
Each of them is provided with a drum bracket 6, and a support shaft 7a of the winding drum 7 is engaged with and held in a concave groove 6a of the drum bracket 6 so as to be rotatable in the lateral direction. In addition, one side (right side in FIG. 2) of the winding drum 7 has a small diameter, so that the root portion of the tape-shaped seedling 10 prevents the root portion side of the seedling roll from becoming huge. ing.

On the other hand, 8 is a seedling guide, and the seedling guide 8 includes a root side guide 8a that guides the root side end of the winding drum 7,
It is composed of a leaf side guide 8b that guides the leaf (stem) side end and a standing guide 8c provided between both guides 8a and 8b. Side guide
It is formed so that the facing interval becomes narrower as it goes downward with 8b, and the standing guide 8c vertically extends the tape-shaped seedlings 10 in a horizontal direction fed from the winding drum 7 to the lower end side of the seedling mounting table 5. It is sloped so that the more you send it, the more it stands up. Further below the drum bracket 6,
A seedling retainer guide 9 is provided to prevent the tape-shaped seedlings 10 from being unintentionally delivered, and prevents the tape-shaped seedlings 10 from being unnecessarily delivered and loosened.

Here, the tape-shaped seedling 10 is formed as follows. In other words, a seedling P for a unit planting plant with sprouts cut out from a seedbed to a predetermined size, root-washed, and roots and stems cut to a required length from a block-shaped seedling is picked as appropriate to a unit planting plant. The seedlings P are continuously formed so as to be continuously formed by sandwiching and holding the substantially central portion of the planted seedlings P from both sides with tape 10a such as an adhesive tape so as to be inclined with respect to the tape direction. . This product can be manufactured manually, but can also be manufactured mechanically.

Reference numeral 11 denotes a tape guide provided below the seedling placing table 5 so as to correspond to the planting claws 4, and the tape guide 11 is pulled out from the attached winding drum 7 via a guide roller 11a. The tape-shaped seedling tape 10a is guided from left to right toward the seedling scraping side below the slant of the seedling mounting table 5, but on one side of this tape guide 11 (in the drawings of the embodiments, the left side is shown). ) Has a seedling platform structure.
That is, a pair of cam rollers 12 are vertically arranged on one side of the tape guide 11, but the base end boss portion 13a of the crank arm 13 is rotatably provided at a position eccentric from the rotation shaft 12b of the cam roller 12. Has been. A bracket 14a is integrally fixed to the tips of the upper and lower crank arms 13, and the bracket 14a has a comb-teeth shape at a position where the tape 10a is sandwiched from above and below and which is substantially aligned with the seedling pitch of the tape-shaped seedling 10. A plurality (six in the embodiment, for convenience) of the feed claws 14 are respectively projected so that Moreover, the claw positions are arranged so that the left and right sides are different from each other so as to correspond to the planted seedlings P that are inclined with respect to the tape-shaped seedlings 10, and the feed claws 14 are outwardly arranged so that the vertical facing distance becomes wider toward the tip side. The tape is bent toward the inside so that the tape 10a can be securely inserted. Then, as will be described later, the feed claw 14 swings in an arc-shaped crank by the rotation of the cam roller 12, and the planting seedling P
The seeds are fed vertically by the seedling pitch.

On the other hand, reference numeral 15 is a cutter that is arranged so as to correspond to the above-mentioned inclined planting seedling P, and the cutter 15 is a feed claw 14
Of the 10 tape-shaped seedlings sent by
The tape 10a between the next planted seedling P and the seedling P is cut. That is, the pin 15a provided at the base of the cutter 15 engages with the engaging groove 16a formed at the tip of the operating arm 16 pivotally supported by the support shaft 16c on the seedling placing table 5. A cam 12a is provided on the outer peripheral surface of the lower one of the cam rollers 12 so as to project. When the cam 12a contacts the pin 16b provided on the actuating arm 16, the cutter 15 is moved to the right by cutting the tape 10a. Moreover, in this device, the tape cutting position of the cutter 15 is displaced to the lower side so that the lower edge side is cut even if the upper edge side of the tape 10a is left as shown in FIG. 8, that is, the lower side of the planting claw 4 in the planting trajectory direction. The layout is taken into account, which allows the tape
Disturbed seedling posture due to uncut 10a is avoided as much as possible.

Next, the operation timings of the planting claw 4, the feeding claw 14, and the cutter 15 will be described. That is, as shown in FIG. 9, in the process of raising the planting claw 4 near the top dead center, as will be described later, the tape between the earliest (lower) end and the planting seedling P immediately above it is already taped.
Although 10a is cut, in this state, the planting claw 4 scrapes and holds the planted seedling P separated from the cut at a stage in which the planting claw 4 moves to the top dead center and then descends a little.
Figure). On the other hand, at this time, the feed claw 14 rises while retracting from the movement trajectory of the tape-shaped seedling 10. Then, the planting claw 4 descends to near the bottom dead center to plant the scraped planting seedling P in the field, while the feed claw 14 penetrates between the planting seedlings P (first
(Fig. 11). Then, the feeding claw 14 descends in time with the timing when the planting claw 4 crosses the immortal point and moves upward. At this time, the feeding claw 14 is planted by the planting seedling P.
The tape 10a is abutted on both sides, and the planted seedling P is lowered according to the seedling pitch, and the foremost planted seedling P is forcibly transferred so as to be located at the scraping position (No. 12).
Figure). After that, the planting nail 4 will rise, but
The cutter 15, which is cam-operated in synchronism with the ascending stroke, moves laterally to cut the tape 10a between the leading edge and the planting seedling P above it (Fig. 13).
At such timing, seedling feeding, tape cutting, and seedling scraping are performed to perform timed continuous planting.

In the figure, 17 is a seedling guide formed by an elastic plate material provided in the scraping portion of the planting seedlings by the planting claws 4,
The tape-cut planting seedling P is prevented from being inadvertently dropped before being scratched by the planting claw 4, and in response to the thing being scraped by the planting claw 4 and pressed downward. It is elastically deformed and opens like a double door, and sends out downward while adjusting the posture of the planted seedling P. Also
18 is a safety cutter cover, 19 and 20 are stock guides, 21
Is a seedling holding guide, which prevents the tape-shaped seedlings from falling and protects the seedlings, and 22 is a cutter.
There are 15 return missiles.

In the embodiment of the present invention constructed as described above, the winding drum 7 on which an appropriate amount of tape-shaped seedlings are wound is mounted on the seedling mounting table 5, and the tape-shaped seedlings 10 are attached to the tape guides 10a by the tape guides 11. Set seedlings through so that they can be held by. In this way, when the machine is running in the set state and the planting clutch (not shown) is in the continuous state, as described above, the feeding operation of each seedling pitch by the feeding claw 14, the tape cutting operation by the cutter 15, and the tape cutting operation are performed. The planting claws 4 for scraping and planting the planted seedlings P thus planted perform the planting operation with good timing, and thus the continuous planting work of the strawberries is carried out automatically.

As described above, in the present invention, the tape-shaped seedlings P having the predetermined pitch and attached to the tape 10a are used in the present invention, and the tape-cut seedlings are cut at the same timing as the seedling scraping and the planting operation of the planting nail 4. Although the seedlings to be planted in units are supplied, the tape-shaped seedlings wound on the winding drum 7 are accommodated and mounted in a fall shape on the inclined upper end side of the seedling mounting table 5. And it will be fed from here and sent out toward the lower end of the slope and guided, but what was laid down during this sending process is gradually raised and transformed and supplied to the seedling scraping part side. Become. For this reason, it is difficult to maintain the posture of the tape-shaped seedling like the one that guides it from the beginning in the standing posture, and there is no problem that it will easily fall over due to a slight machine vibration etc. It will be supplied to the department side in a proper standing posture. As a result, the problem that the scraping of the planting seedlings is disturbed can be reliably avoided, and the seedling scraping performance of the planting nail 4 is improved.

[Operation and Effect] In summary, since the present invention is configured as described above, the tape-shaped seedlings stored in the seedling storage section of the seedling mounting table are fed out and guided to the seedling scraping section side. However, in the process of being fed out and guided, the planted seedlings, which had been in the lying posture, are gradually guided to stand up and then are brought to the standing posture, and are fed to the scraping section side. Therefore, from the beginning there is no problem that the planting seedlings fall down like the tape-like seedlings that are sent out in the standing posture, and the planting seedlings can be supplied in a standing posture without falling to the seedling scraping part side. Therefore, it is possible to prevent scraping from occurring and the seedling posture is disturbed, and it is possible to plant seedlings with high accuracy.
