Description

[Detailed Description of the Invention] The present invention relates to a vertical feeding device for seedling pine in a rice transplanter.

In other words, the upper part of each star foil can be seen through each slit arranged in parallel at the bottom of the seedling stand, and a rotatable vertical feed cam comes into contact with a driven cam extending from the shaft of the star foil, so that each star In a rice transplanter configured to be able to vertically feed seedling mats by rotating the foil, each star foil is positioned high above the slit and protrudes when vertically feeding the seedling mats to powerfully and reliably feed the seedling mats vertically. In addition, when not in operation, each star foil only protrudes slightly above the slit to prevent it from getting entangled with the roots of the seedling pine and to prevent it from getting in the way when seedlings are being transferred, allowing for reliable vertical feeding. The present invention provides a simple structure that allows for convenient implementation.

Next, the embodiment shown in the drawings will be described.

In Figures 1 to 6, Figure 1 shows a side view of the entire rice transplanter, with a float 8 that is long in the front and back direction.
An engine E is mounted on the upper front part of the aircraft, and both swing transmission cases 10 each having a wheel 9 mounted thereon are mounted on both rear sides of the engine E, and a planting case 11 at the rear of the fuselage and a lower float 8 rear part are installed. A planting depth adjustment lever 12 is interposed between the planting case 11 and a handle 13 extending from the rear upper part of the planting case 11 to the rear of the machine.
The lower part of the seedling stand A diagonally installed in front of the handle 13 is installed so that it can reciprocate in the lateral direction along the horizontally installed seedling take-out plate 14, and both planting claws 15 are attached to the seedling take-out plate 1.
4, the block seedlings are scraped from the seedling pine and installed so as to be planted on the rice field, and are constructed in the same manner as the conventional structure.

In addition, a plurality of slits 2 are arranged in parallel on the lower surface of the lower side of the seedling platform A having both seedling mounting surfaces, and the upper part of each star foil 3 is inserted into each slit 2 at the rear from the shaft 4. A driven cam 5 is extended, and an end of a vertical feed cam 6 is fitted onto a shaft 16 which protrudes from the rear side of the planting case 11 and rotates intermittently. When moving to the horizontal end, the vertical feed cam 6 rotates and the driven cam 5
The driven cam 5 is rotated upward by touching and lifting from below, and each star wheel 3 is installed so that it can be rotated in the vertical feeding direction, and has the same structure as the conventional structure. do.

The shaft 4 of each star foil 3 fits into an elongated hole 18 in the vertical direction formed in a bracket 17 vertically disposed below the lower surface of the seedling stand A, and the lower surface of the seedling stand A is located above the slit 2. Support metal 19 hanging below the
The upper side of the stay 20 that pivotally supports the shaft 4 is pivotally supported via a pin 21, and the star honor 3 is placed between the upper side of the stay 20 and the lower support piece 22 of the seedling stand A. When the shaft 4 is lowered to the lower end of the elongated hole 18, the upper part of each star foil 3 slightly protrudes above the slit 2, and the shaft 4 is inserted into the elongated hole. The star foil 3 is installed and configured so that the upper part of each star foil 3 protrudes high above the slit 2 when raised to the upper end side of the star foil 18.

FIG. 7 shows another embodiment, which has the same structure as the previous embodiment as indicated by the same reference numerals, but the middle part of the stay 23 that extends long along the bottom of the seedling stand A is It is pivotally supported via a pin 25 to a support piece 24 vertically provided on the lower surface of the mounting table A, and the shaft 4 of each star foil 3 is mounted on the front end of the stay 23, and the rear end of the stay 23 is used for mounting seedlings. A stay 23 is inserted into a slit 26 formed on the lower surface of the rear side of the table A, is connected to a plate 27 facing upwardly on the upper surface of the rear side of the seedling table A, and extends downward on the rear side of the table A. rear end and seedling stand A
A tension spring bullet 7 is interposed between the lower surface and the lower surface.

Therefore, when the star wheel 3 is inactive,
As shown in FIGS. 3 to 5, the shaft 4 is pressed against the lower end of the elongated hole 18 by the bullet 7, and the upper part of each star foil 3 slightly protrudes above the slit 2. Thus, the lower surface of the seedling pine and the star foil 3 can be engaged without causing root entanglement, and since it only protrudes slightly in this way, it does not get in the way of seedling succession.

In addition, when the seedling table A moves to the end and vertically feeds the seedling pine, as shown in FIG. As the driven cam 5 is rotated, each star wheel 3 is also rotated in the vertical feeding direction. Since the driven cam 5 is rotated while being lifted as shown by the arrow B, the shaft 4 is aligned with the slotted hole 4. As it moves upward to the upper end side, the upper part of each star foil 3 rises high above the slit 2 as shown by the arrow 11, so that the star foil 3 is sufficiently bitten into the lower surface of the seedling pine. At the same time, vertical feeding can be performed by lifting the paper upward.

When the vertical feeding is completed, the bullet is lowered again by the force of the bullet 7.

In another embodiment shown in FIG. 7, similarly to the previous embodiment, during vertical feeding, the upper part of the star foil 3 rises above the slit 2 as indicated by arrow D, as shown by the imaginary line. , vertical feeding is carried out while rotating, but at the same time, the swinging of the stay 23 lowers the plate 27 onto the top surface of the seedling platform A as shown by the arrow H, and until then the upper side of the seedling pine is suspended. I lowered the table that I had been lifting and placed it on seedling stand A.
It will work to improve the slippage at the top.

In this way, the present invention allows the upper part of each star foil 3 to be seen through each of the slits 2 arranged in parallel at the lower part of the seedling stand A, and also allows the driven cam 5 extending from the shaft 4 of the star foil 3 to rotate. In a rice transplanter configured so that a freely adjustable vertical feed cam 6 comes into contact with the star foil 3 and the seedling pine can be vertically fed by rotation of each star foil 3, the upper part of each star foil 3 is vertically moved above each slit 2. The shaft 4 of each star foil 3 is mounted below the seedling stand A so as to be movable up and down, and each star foil 3 is compressed downward by a bullet 7, and the vertical feed cam 6
Since each star foil 3 is configured to be positioned upward and vertically fed only when it comes into contact with the driven cam 5, when the seedling pine is vertically fed, each star foil 3
protrudes high above the slit 2 to enable strong and reliable vertical feeding, and also to engage with the underside of the seedling pine when not in operation to prevent it from becoming entangled with the roots of the seedling pine. It only protrudes slightly above the slit 2 so as not to get in the way during seedling splicing, and has a simple structure that allows reliable and good vertical feeding and can be carried out suitably.
