Description

[Detailed Description of the Invention] The present invention relates to a seedling holding device for a rice transplanter.

Pine seedlings placed on the seedling stand of a rice transplanter may slide down the sloping seedling stand, come up in the middle and buckle, or turn around and fall off due to the vibration of the machine. . Particularly in the case of pine seedlings made up of multiple paper pot seedlings, the adhesive between the individual paper pot seedlings is weak due to the glue, so the final seedlings in the horizontal movement process are Before harvesting is complete, the paper pot seedlings on the front end peel off and move forward toward the space after scraping, resulting in poor planting posture, or two seedlings at once.
This may cause inconveniences such as scraping off the stock.

As a countermeasure to this problem, it has been proposed to fix a metal fitting close to the top of the seedling stand to restrict the vertical movement of the seedlings, but this has a structure that directly presses the pine seedlings from above. Therefore, if the thickness of the soil bed differs, the height must be adjusted each time. If this adjustment is not made, there will be a problem that if the seedling regulating fitting is low, the pine seedlings will get stuck between the seedling rest and the seedling regulating fitting, making it impossible to feed vertically, and if it is high, the seedling regulating fitting will not function. There is.

Another problem is that at the end of the planting work or when planting along the ridge, the fixed seedling regulating fittings get in the way and make it difficult to pull out the pine seedlings from the seedling stand.

The purpose of this invention is to solve the above-mentioned problems with conventional devices, and to prevent pine seedlings from falling off the seedling stand, floating up, and buckling, without having to adjust the height of the seedling stand, allowing for highly accurate planting. An object of the present invention is to provide a seedling regulating device for a seedling stand in a rice transplanter that makes it possible to do so. Another purpose of the present invention is to prevent pine seedlings from falling off, floating up, and buckling as described above, as well as to pull out pine seedlings from the seedling stand at the end of planting work or when planting at the edge of a ridge. An object of the present invention is to provide a seedling regulating device for a seedling stand in a rice transplanter that facilitates the use of seedlings.

The seedling regulating device of the seedling stand in the rice transplanter of the present invention, which achieves the above object, moves the seedling stand on which the pine seedlings are placed reciprocatingly from side to side, while the pine seedling stand faces the seedling scraping opening of the fixed front side frame at the lower end. In a rice transplanter that scrapes each seedling one by one and vertically feeds the pine seedlings at the end of the horizontal movement of the seedling platform, a pair of left and right controls are provided for regulating the leaves and stems of the pine seedlings from the left and right along the vertical feeding direction. A linear guide rod is provided with its free end facing the scraping side from the upper side in the longitudinal feeding direction, and the scraping side free end of the linear guide rod is configured to have a facing width narrower than the facing width on the upper side. It is characterized by the fact that Furthermore, the present invention is characterized in that a plurality of sets of the above-mentioned left and right pairs of linear guide rods are provided, and each set of linear guide rods can be independently switched between a position along the top surface of the seedling stand and a position where it stands up. be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

A fixed front side frame 7 fixed to the machine frame is provided opposite the lower end of the seedling stand 2, and the seedling stand 2 is provided so as to be able to reciprocate horizontally from side to side with its lower end in contact with this fixed front side frame 7. ing. While the seedling platform 2 is moving back and forth, the pine seedlings P are scraped one by one from the seedling scraping opening 7a of the fixed front side frame 7 by the planting claws 3. Further, a vertical feed roller 8 is provided on the lower surface side of the seedling table 2, and a part of this vertical feed roller 8 is attached to the seedling table 2.
It protrudes to the top surface side through the opening 2a on the bottom surface. The vertical feed roller 8 rotates intermittently every time the seedling tray 2 is moved horizontally to the left or right, and
The upper pine seedlings P are vertically fed by an amount equivalent to one plant toward the fixed front side frame 7 side.

A seedling holder 10 is fixed above the lower end of the seedling stand 2 via brackets 9 at both ends so as to extend laterally, and this seedling holder 10 supports the leaves of the seedlings to prevent them from falling forward. I try to do that. On the rear side of the seedling holder 10, a pair of left and right linear guide rods 11 constituting a seedling regulating device are installed so as to extend rearward above the seedling rest 2. A plurality of sets are provided at appropriate intervals in the width direction for each strip. The linear guide rod 11 is constructed by bending a single elastic wire such as a hard steel wire, and the central bent portion 11a serves as the mounting portion 11a for the seedling holder 10, and the rods are arranged in pairs. It bends downward from the upper auxiliary rods 11'b, 11'b that extend left and right, and through these auxiliary rods 11'b, 11'b, the parallel parts 11b, 11b and the tip of the pine seedling bed are bent downward. It has free ends 11c, 11c. Linear guide rod 1
1 is held by the seedling holder 10 in the mounting part 11a, and the auxiliary rods 11'b, 11'b are extended toward the upper side of the seedling holder 2 in the vertical feeding direction to the upper side past the vertical feeding roller 8, and then The curve is reversed downward, and the parallel portions 11b, 11b are again placed along the seedling stand 2, with the free ends 11c, 11c reaching the lower fixed front side frame 7 in the vertical feeding direction. Auxiliary rod 11'b and parallel portion 11b of linear guide rod 11
is generally parallel to the vertical feeding direction of the pine seedling P, and the lower parallel part 11b is the part of the leaf and stem part p _a of the seedling and is located above away from the bed soil part p _b . ing. Furthermore, the free ends 11c are inclined so that they approach each other toward the tips, and the width l ₁ at the tips is smaller than the width l ₂ of the parallel portion 11b.

The mounting portion 11a of the linear guide rod 11 is configured to be held via a bracket 12 fixed to the seedling holder 10, as shown in FIGS. 5 and 6. The bracket 12 has a pair of elongated holes 12a, 12
a, hook-shaped locking part 12b, pair of concave locking parts 12
c, 12c, and as shown in FIG.
b, and the arms on both sides are connected to the elongated holes 12.
a, 12a, and a position where the parallel part 11b and the free end part 11c sink into the leaf and stem part p _a of the pine seedling P to hold the seedling, and a hook-shaped locking part as shown in FIG. Remove the mounting part 11a from the linear guide rod 12b, rotate it upward by about 90 degrees, and lock it in the upper part of the elongated hole 12a and the concave locking parts 12c, 12c.
1 can be alternately switched between the upright position and the upright position. This holding mechanism is provided for each linear guide rod 11. Therefore, the plurality of linear guide rods are arranged at positions along the upper surface of the seedling stand 2 that independently holds the seedlings, and at different positions. It is possible to switch between the two positions.

In the above-mentioned device, the linear guide rod 11 is
When locked as shown in the figure, the parallel portion 11b and the free end portion 11c are in a state of being immersed in the pine seedling P, as shown in FIGS. 7 and 8. The parallel portion 11b has the function of guiding the leaf and stem portions p _a of the pine seedlings P within a width l ₂ in parallel to the vertical feeding direction of the seedlings, and the pine seedlings P are scraped off and successively moved to the front fixing side frame 7 side. As it progresses, it gradually narrows to a width _l1 at the free end 11c, and is held from both sides. That is, as shown in FIGS. 9 and 10, the leaf and stem part p _a of the seedling is bent inward by the free end 11c of the linear guide rod 11, which acts to restrict the progress of the pine seedling P. You will receive
Therefore, although the pine seedlings P advance against the active vertical feeding action of the vertical feeding rollers 8, they do not fall off due to vibrations of the machine body or the like.

In addition, neither the parallel portion 11b nor the free end portion 11c of the linear guide rod 11 presses the bed soil portion p _b of the pine seedling P, but is positioned above it, so that the bed soil portion p _b There is no need to adjust its height regardless of its thickness.

Further, in the above-mentioned device, the linear guide rod 11 is the third
As shown by the chain line in the figure and as shown in FIG. 6, it can be switched to a position where it stands up against the seedling stand 2. Therefore, when the planting work is completed or when planting along the ridge, pine seedlings P.
When it is necessary to take out the seedlings from the seedling stand 2, by raising the linear guide rod 11, the seedlings can be taken out easily without any hindrance. In addition, since the linear guide rods 11 can be operated individually, if the braking becomes too hard depending on the quality of _the seedlings, such as when the leaf and stem parts of the seedlings are too hard, multiple sets of linear guide rods 11 can be operated. By erecting only some of the linear guide rods, smooth vertical feeding can be achieved.

As described above, the seedling regulating device for the seedling rest in the rice transplanter according to the present invention moves the seedling rest holding pine seedlings back and forth from side to side, and controls the pine seedlings facing the seedling scraping opening of the fixed front side frame at the lower end. In a rice transplanter that scrapes each seedling one by one and vertically feeds the pine seedlings at the end of the horizontal movement of the seedling platform, a pair of left and right controls are provided for regulating the leaves and stems of the pine seedlings from the left and right along the vertical feeding direction. A linear guide rod is provided with its free end facing the scraping side from the upper side in the longitudinal feeding direction, and
Since the free end of the linear guide rod on the scraping side is configured to have a narrower opposing width than the opposing width of the upper side, the linear guide rod does not press against the bed soil of pine seedlings, and the sloping free end allows The leaves and stems can be held in place by pinching them, so there is no need to adjust the height of the linear guide rod depending on the thickness of the soil layer, preventing pine seedlings from falling off or buckling due to floating. This enables highly accurate planting work with correct planting posture and accurate number of plants. In addition, if the linear guide rod of the seedling regulating device is made to be freely switchable between a position along the top surface of the seedling tray and a position where it stands up, it can also have the effect of making handling such as taking out pine seedlings easier. .
