Abstract

PURPOSE:To prevent the unexpected excess sowing by inclining the upper face of an upper sowing plate relative to the lower setting face of a frame of sowing machine in such a manner as to roll the seeds toward one side in the moving direction of the sowing plate. CONSTITUTION:Seeds are change on an upper sowing plate 4 and put into the holes 5 of the plate. The sowing plate 4 is inclined and pulled toward the direction of the arrow (a) against the force of a spring until the hole 5 coincides with the hole 3 of the lower sowing plate 2. The seeds are sowed through the holes. The excess seeds caught on the hole 5 of the upper sowing plate 4 removed from the hole 5 by the transfer motion of the sowing plate and rolled toward the inclined direction. Accordingly, unexpected excess sowing caused by the entering of the excess seed into the coinciding upper and lower holes 3, 5 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a manual seeding machine for sowing seeds one by one at regular intervals.

Prior Art Conventionally, two seeding plates, each having leakage holes through which seeds can pass, are perforated at a predetermined pitch in the left-right and front-back directions, are stacked one on top of the other.
Move one of the seeding plates to change the position from a state in which the leakage holes in the upper seeding board and the leakage holes in the lower seeding board do not match vertically to a state in which they do, and remove the leakage in the upper seeding board. A seeding machine is known in which the seeds that remain in the holes are sown by passing through the leakage hole of the lower seeding plate. However, in this seeding machine, the bottom surface of the machine frame and the top surface of the seeding plate were made parallel to each other.

Problems to be Solved by the Invention With conventional seeding machines, when the seeding machine is set on the floor where the seeds are to be sown or on top of the seedling box, the seeds that have entered the leakage holes in the upper seeding board are removed from the lower side. When the seeding board is moved so that it enters the leakage hole of the seeding board and falls, when the seeds that are caught in the upper leakage hole come off the hole and move, they do not roll in a fixed direction, There was a drawback that the seeds remained in the vicinity of the holes, and when the upper and lower leakage holes overlapped, the seeds were accidentally sown and two seeds were sown.

Means for Solving the Problems In order to solve the problems of the conventional art, the present invention provides a structure in which leakage holes 3 and 5 through which the seeds 14 can pass are bored at a predetermined pitch in the left-right and front-rear directions and stacked one on top of the other. At least one of the seeding plates 2 and 4 is moved so that the leakage hole 5 of the upper seeding plate 4 and the leakage hole 3 of the lower seeding plate 2 are brought into alignment from a state where they do not vertically match. In this seeding machine, the seeds 14 that remain in the leakage holes 5 of the upper seeding plate 4 are sown by passing through the leakage holes 3 of the lower seeding plate 2. - of the upper seeding board 4 with respect to the lower end installation surface
The seeding machine is characterized in that the first surface is inclined so that the seeds 14 roll on one side in the moving direction of the seeding plate 4.

Functions and Effects of the Invention According to this invention, after putting seeds on the upper seeding plate and fitting the seeds into the leakage hole, the seeding machine is placed on the second side of the seeding bed or the seeding box containing the seeding bed. Once set, the upper seeding plate will be tilted. In this state, one of the seeding plates can be moved to match the leakage hole in the lower seeding plate, allowing the seeds to be inserted to leak out and be sown. In this case, if the excess seeds caught in the leakage hole of the upper seeding plate come off from the hole due to the shock of moving the seeding plate, they will roll away from the hole in an inclined direction and will not remain in the vicinity and will polymerize. This prevents two seeds from entering the upper and lower leakage holes and accidentally sowing them.

Example 1 is a frame for a seeding machine, with a width of about 70 cm in the left and right direction.
It is shaped like a rectangular bottomless box measuring approximately 35 centimeters in the front and back direction. A lower seeding plate 2 that is inclined in the left-right direction is stretched between the two lower sides of the frame 1. In this lower seeding plate 2, leakage holes 3 through which seeds can freely pass are formed at a constant pitch in the left-right direction and the front-back direction.

Incidentally, this seeding board 2 is made of transparent synthetic resin.

Reference numeral 4 denotes an upper seeding plate, which is also made of transparent synthetic resin, and has swirl holes 5, which are slightly smaller than the swirl holes 3, formed at the same pitch. The upper seeding plate 4 is provided so as to be movable in the left-right direction, and is urged to one side by a spring 6, so that the holes 3 and 5 do not match in the normal state, and are held against the spring 6. When the seeding plate 4 is moved, the holes 5 match the holes 3 in the seeding plate 2 below. On the same side, the seeding plate 4 is pulled in the direction of arrow A against the spring 6, but it may be pushed in the opposite direction of arrow A to align the upper and lower holes 3 and 5. Of course. 7
indicates a guide pin.

Reference numeral 8 denotes a protruding strip for preventing the seeds from moving in the front-back direction and making it difficult for the seeds to enter the leakage hole 3.

Next, the operation of the upper side will be explained.

Seedling raising pots 9 are arranged left and right and front and back at the same pitch as the leakage holes of the seeding machine, and the seedling raising device A is made of paper and has a continuous periphery on the opening side.
1. Prepare a seeding bed that is inserted in an inverted state into a container. and,
The sprouting hole 12 in the center of the head on the upper side of each bot 9
A seeding hole 13 is formed inside. Then, in the upper part of this seeding bed, seeds 14 made into spheres by coating the upper surface of the upper seeding plate 4 with seeds of vegetables, etc. are placed, and one seed 14 is placed in each leakage hole 5 while tilting to the left and right as appropriate. Set the seeding machine so that the leakage hole 3 of the lower seeding plate 2 is exactly located directly behind the seeding hole 13 of the pot 9.

At this time, the seeding plate 4 is tilted upward to the left, and the extra seeds 14a cannot be completely inserted into the holes 5 and remain engaged with the leakage holes 5 at various locations. In this state, when the upper seeding plate 4 is moved to the left and right against the spring 6, the extra seeds 14a come off from the holes 5 and roll due to the shock. On the other hand, the seeds 14 fitted in the leakage hole 5 are removed from the leakage hole 3 of the lower seeding plate 2
The seedlings pass through and are reliably sown into the seeding holes 13 of each bot 9 at the bottom. The extra seeds 14a that roll away from the leakage hole 5 are caused by the inclined seeding plate 4, so the seeds 14a do not stay near the hole 5, but forcefully roll to the right and end up at one end of the seeding frame. Accumulate.

Therefore, the situation where the seeds 14 accidentally fall from the leakage holes that overlap one above the other and two seeds are sown in the seeding hole 13 of the bot 9 does not occur.

Note that the upper and lower seeding plates 2 and 4 must be made transparent so that the lower seeding bed can be seen through them, otherwise the seeding holes 13 will be accurately aligned.
It is not possible to align the lower leakage hole 3 with the seed, making it impossible to sow seeds accurately. However, simply being transparent makes it difficult to determine whether or not the seeds 12 are in the leakage hole 5 of the upper seeding plate 4. Therefore, in order to eliminate such shortcomings,
It is very convenient to use the form shown in FIG. 5, in which a green, pink, or blue color that is easily distinguishable from the seed color (coating color) is applied near the leakage hole 5. In FIG. 5, the colored area opening to which the base line has been applied is circular, but it is not limited to a circular shape. Note that this coloring may be applied to the upper seeding board 4 or the lower seeding board 2, or the entire seeding board may be colored in some cases.

Furthermore, as another idea, when the seeding plates 2 and 4 are transparent, the coating color of the seeds 12, which is normally white or gray, may be pink, blue, or green. Furthermore, when applying colored coating, it is more convenient to change the color depending on the variety or vegetable name to avoid sowing the wrong seeds.
