Description

[Detailed description of the invention] The present invention is a simple seeding device that sows seeds from above a stationary seedling-raising container.The feature is that the stationary seeds are dropped directly below and accurately sown inside the seedling-raising container. It's there to do.

BACKGROUND ART Conventionally, it has been widely practiced to sow seeds of rice, vegetables, beets, etc. in seedling containers such as paper pots, and after raising the seedlings, transplant them to a main field. When sowing seeds into seedling-raising containers, it is desired to sow the seeds accurately in a predetermined position, and a large number of seeding devices have been announced. The majority of conventional seeding devices transport seedling containers continuously under a continuously rotating seeding drum and sow seeds into them. Therefore, when seeds are sown in small-diameter seedling-raising containers such as paper pots, the seeds do not fall exactly in the designated place, and there are paper pots where the seedlings do not germinate after being raised. For this reason, if accuracy is desired, a seeding board is placed on top of a paper pot and the seeds are sown in a stationary state, but this method has the disadvantage of being extremely inefficient and requiring a lot of manpower.

The inventor of this invention conducted research to develop a simple device that could accurately and efficiently sow seeds, and focused on sowing seeds in a stationary state, dividing the frame of the sowing machine into an upper stage and a lower stage. A seeding board with seeding holes drilled in it is fixed between a pair of upper machine frames, and a pair of seed guiding frames whose bottom plate is a seed holding plate that slides into contact with the lower surface of the seeding plate is movably mounted on the upper machine frame. A flat brush is fixed perpendicularly between a pair of seed guiding frames, the central part is used as a seed chamber, the left and right sides of the seed chamber are used as seed adjustment chambers, and the space between the lower machine frames is used for carrying seedling containers. A seeding machine is provided with a road and a stop plate, a drive shaft is passed through between the pair of seed guide frames, drive rollers are provided on both sides of the drive shaft and are opposed to each other on the machine frame, and the left and right Each seed conditioning chamber is equipped with a rotating brush, and a belt is hung between the axis of the rotating brush and the drive shaft to interlock them, and by moving the seed guiding frame, the seed conditioning chamber can fill the seeding holes that are not filled in the seed chamber. The problem was solved by filling the seed with seeds, holding them with a seed holding plate, and when the seed holding plate moves, they fall directly below the edge of the plate and fall into the seedling growing container located between the lower machine frame and the machine frame. .

To explain an example of the present invention about a device for sowing seeds in paper pots, 1, 1 indicates an upper machine frame, 2, 2 indicates a lower machine frame, and they form a pair, respectively.
1 and the lower machine frames 2, 2 are vertically opposed to each other. A connecting frame 3 is fixed between the upper and lower machine frames 1 and 2 so that the vertical interval is always constant. A seeding plate 4 is stretched between the upper machine frames 1 and 1, and a large number of seeding holes 5 are bored in the seeding plate 4 according to the pitch of each cylinder of the paper pot in which seeds are to be sown. Further, when the seeding plate 4 is made of an iron plate or the like, it can be made integrally with the upper machine frame 1, and the longitudinal side portions of the seeding plate 4 may be bent to form the machine frame 1.
The number and size of the seeding holes 5 are determined appropriately depending on the size of the seeds and the number of seeds to be sown, and they should always correspond vertically to each cylinder when the paper pot is unfolded, and should be arranged so that the holes 5 are outside the length of the paper pot. Both ends 4
There is no need to drill holes in a and 4b.

A seed guiding frame 6 is movably attached to the pair of upper machine frames 1, 1 so as to surround them from the outside. A seed holding plate 7 is located below the seeding plate 4, and the lower surface of the seeding plate 4 and the upper surface of the seed holding plate 7 are in sliding contact with each other. Therefore, even if the seeds are in the seed guiding frame 6 and enter the seeding hole 5, they do not fall, but only when they leave the seed holding plate 7 do they lose support and fall. In addition, a drive shaft 8 is installed horizontally in the center of the seed guiding frame 6 above the seeding plate 4, and rotatably penetrates both sides of the seed guiding frame 6.
A drive roller 9 is fixed to a portion facing the upper part of the machine frames 1, 1, and a handle 10 is attached to one outer end. Therefore, when the handle 10 is rotated in the direction of arrow A, the seed guiding frame 6 moves the seed holding plate 7 to the seed plate 4.
Slide it into contact with the bottom surface of and move it in the direction of arrow B. Further, flat brushes 11, 11 are provided on the front and rear of the seed guide frame 6, sandwiching the drive shaft 8, and the tips of the flat brushes 11, 11 are brought into contact with the upper surface of the seeding board 4. flat brush 1
1 and 11 are made of strong fibers such as nylon,
It is best to use something that is as resistant to wear as possible. A seed chamber 12 is constituted by the flat brushes 11, 11, and seeds to be sown are always kept in this chamber. And on the outside of the flat brushes 11, 11, the flat brush 1
3 and 13 are provided in parallel to each other, and the chamber configured between the flat brushes 11 and 13 is called the seed adjustment chamber 1.
4 and eggplant. Further, rotating brushes 15, 15 are provided in the seed adjustment chambers 14, 14 in parallel with the flat brush 11,
The tip of the rotating brush 15 is brought into contact with the upper surface of the seeding plate 4. A pulley 17 is fixed to the outside of the shaft 16 of the rotating brush 15, and a belt 19 is strung between it and the pulley 18 of the drive shaft 8, and the belt 19 rotates in conjunction with the pulley 18 in the directions of arrows C and D. Reference numeral 20 denotes a regulation guide, which is fixed to the lower inside of the seed guiding frame 6 and holds the sowing plate 4 and the seed holding plate 7 so that they do not shift at all times. Reference numeral 21 denotes a seed holding plate cushion. 22 is a roller whose shaft 23 is fixed to the seed guide frame 6 and is in contact with the lower surface of the flange of the upper machine frame 1. , which assists the normal movement of the seed guide frame 6.

In the lower machine frame 2 parallel to the upper machine frame 1, a number of rollers 24 are rotatably provided between the machine frames 2, 2.
Base plate 27 with paper pot 26 developed on it
can be placed so that it can move freely back and forth. Then, release the 1st side of the lower machine frames 2, 2, and press the base plate 2 from the released side.
7 can be pushed in or pulled out to form a conveyance path for the seedling raising container, and a stop plate 25 is fixed on the side opposite to the release side, and a paper pot 26 is conveyed.
so that it stops at a predetermined position.

The device of the present invention is constructed as in the above example, and to explain an example of its operation now, the paper pot 26 is unfolded on the base plate 27, soil is filled therein, and the open side of the lower machine frame 2 is opened. Insert it further until it reaches the stop plate 25 and stops. Next, the seed guide frame 6 is moved to one end, and a large amount of seeds are placed in the seed chamber 12 in the seed adjustment chamber 14.
When a small amount of seeds are put in the container and the handle 10 is rotated in the direction of arrow A, the rotating brush rotates in the directions of arrows C and D, and the seed guide frame 6 moves in the direction of arrow B.
At this time, the seeds in the seed chamber 12 first enter the seed hole 5, but the amount may be more than the specified amount,
Alternatively, holes 5 that do not enter at all coexist. As the seed guide frame 6 advances, the rotating brush moves while rotating, reaches the hole 5, and sweeps up the seeds in the seed conditioning chamber 14, so the excess seeds in the hole 5 are swept out, leaving the empty hole. Seeds enter the holes 5, and the holes 5 are completely filled with seeds. At this time, the seeds are held down by the seed holding plate 7 and do not fall. As the seed guide frame 6 further advances, the flat brush 13 comes into contact with the seeding hole 5 filled with the seeds and sweeps them up to improve the filling accuracy, but the excess seeds do not go out of the seed adjustment chamber 14 and are filled with the seeding hole 5. Only the seeds that enter 5 will come out. When the seed guiding frame 6 moves further forward, the seed holding plate 7 leaves the seeding hole 5 containing the seeds, so that the seeds lose their support and fall toward the paper pot 26 located below. At this time, the paper pot 26 is stopped at a predetermined position by the stop plate 25, and the sowing plate 4 does not move, so the seeds fall directly below and are not disturbed.
Therefore, sowing is always done accurately, and there is no uneven sowing caused by conventional sowing machines.

As described above, the present invention allows seeds to be evenly sown in the seedling-raising containers placed below by simply moving the seed guiding frame 6 from side to side.Seasoning-raising containers can be used not only in the above-mentioned paper pots, but also in plastic pots, seedling boxes, etc. Many seedling containers can be used.
