[Problems to be Solved by the Invention]

However, in such a conventional artificial seed sowing device, as described above, a large number of dispersion holes capable of containing artificial seed capsules at predetermined intervals in four directions are formed on the surface of the flat dispersion plate, Further, the capsule is rolled by its own weight by rocking the dispersion plate along a number of V-shaped valleys formed in parallel with the surface of the dispersion plate to enter the dispersion hole. . Therefore, the artificial seed capsule having a high viscosity is hard to roll by itself due to its own weight, which makes it difficult to enter the dispersion holes of the dispersion plate.

Further, if the swinging angle of the dispersion plate is increased, the capsule will easily roll, but the acceleration applied to the capsule at that time will increase, so the capsule will pass through the dispersion hole of the dispersion plate and enter the dispersion hole sufficiently. There was a risk of not getting stuck.

The present invention has been made in view of the above points, and a large number of sweepers are provided by arranging the sweepers on the upper surface of the dispersion plate and reciprocating the sweepers along the V-shaped valley in synchronization with the swing of the dispersion plate. It is an object of the present invention to provide an artificial seed sowing device that allows capsules to easily and evenly enter the dispersion holes.

In order to configure the above object, in the artificial seed sowing device of the present invention, a supply hopper for supplying spherical capsules to the dispersion plate is provided, and further, dispersion holes capable of accommodating a large number of artificial seeds at equal intervals in the dispersion plate. Make a hole. A plurality of valleys are formed in parallel along this dispersion hole to form a rolling path of the capsule, and
A seeding plate is arranged closely below the dispersion plate, and the seeding plate is provided with the same number of seeding holes that match the distribution holes of the dispersion plate. Further, a swinging device for swinging the dispersion plate and the seeding plate at a predetermined angle and a dispersion plate sliding device for sliding the dispersion plate with respect to the seeding plate by a predetermined distance are provided, and the swinging device is shaken on the upper surface of the dispersion plate. A sweeper that operates in synchronism with the movement and moves along the valley of the dispersion plate is provided.

[Work]

In the artificial seed sowing device of the present invention configured as described above, the capsule is supplied from the supply hopper onto the dispersion plate, the sliding device is operated to swing the dispersion plate and the seed plate, and the capsule is distributed to the dispersion plate.

In addition, shim 40 is provided on the lower surface of both ends of the sweeper support 3A.

Next, the operation of the artificial seed sowing apparatus of the present invention configured as described above will be described.

First, the capsule C is housed in the supply hopper H, the tray containing the seedling raising mat is placed directly under the dispersion plate 1 and the sliding plate 2, and the capsule C is supplied from the supply hopper H to the upper surface of the dispersion plate 1.
To supply. After the capsule C is supplied to the dispersion plate 1, the rocking mechanism 4 is operated by an air cylinder or the like to rock the dispersion plate 1 about the main shaft 18 so as to tilt forward, for example, by 15 °. The capsule C in the valley 1B naturally rolls along the valley 1B by its own weight and enters the dispersion hole 1A of the dispersion plate 1.

However, the capsules are artificial seeds with extremely high viscosity, so they are hard to roll. Therefore, in the present invention, the forward / reverse drive motor 22 is normally rotated in synchronization with the forward tilting movement of the dispersion plate 1,
While guiding the sweeper 3 with the guide plate 38, the arrow F in FIG.
Move in the direction. As a result, a force is applied to the capsule C in the valley 1B engraved on the surface of the dispersion plate 1 so as to sweep it from the rear, and the capsule C is evenly filled in the dispersion holes 1A of the dispersion plate. At the same time, it is sent in the direction of the stopper 9.

Then, when the oscillating mechanism 4 is actuated by the air cylinder or the like to oscillate the dispersion plate 1 so as to incline backward, the capsule C blocked by the stopper 9 moves in the opposite direction when the dispersion plate 1 inclines backward. It inverts, rolls along the valley 1B, and enters the dispersion hole 1A containing no capsule C. Therefore, the capsules C are evenly housed in the dispersion holes A, and two or more capsules C do not enter the same dispersion hole. At that time, the forward / reverse drive motor 22 is further rotated in reverse in synchronization with the rearward inclination of the dispersion plate 1 to move the sweeper 3 in the direction of arrow R in FIG. As a result, a force is applied to the capsule C so as to sweep it from the rear, and the capsule C is evenly accommodated in the dispersion holes 1A where the artificial seed did not enter.

Further, the dispersion plate and the seeding plate 2 are rocked by the rocking mechanism 4 to return to the horizontal position, the drive motor 22 is normally rotated again, and the sweeper 3 is returned to the stopper 9 side (direction of arrow F). Reverse the motor 22. This makes sweeper 3
Returns again to the direction of arrow R in FIG. 1, and removes the capsules excessively supplied onto the dispersion plate 1 from the dispersion plate 1.

On the other hand, the tray lift mechanism is operated to raise the tray by a predetermined amount. After that, the sliding cylinder 20 is operated to slide the dispersion plate 1 against the seed plate 2, and the dispersion hole 1A of the dispersion plate 1 is moved.
And the seeding holes 2A of the seeding plate 2 are matched. As a result, the capsules C that have entered the dispersion holes 1A pass through the seeding holes 2A of the seeding plate and fall into the holes of the seedling raising mat by their own weight, and a large amount of capsules C are seeded on the seedling raising mat at the same time. After that, the seedling-raising mat for which seeding has been completed is sent out together with the tray onto a free roller conveyor by an electric roller conveyor or the like, and is carried out onto a carry-out table.

[Effects of the Invention] The present invention is configured as described above, so that a spherical capsule that is gel-like and has elasticity like artificial seeds and that is extremely weak against shearing, rubbing, etc. is sown on a seedling mat. In this case, by utilizing the synergistic effect of the natural rolling of the capsule itself and the sweeping action of the sweeper, a large amount and easy seeding can be performed on the seedling-growing mat without damaging the capsule. Further, since a plurality of valleys are formed in parallel along the row of a large number of dispersion holes provided on the dispersion plate, and the dispersion plate is swung by a sweeper while being swung by a predetermined angle, the dispersion holes of the dispersion plate are formed. Capsules can be evenly inserted in the capsule, and then the dispersion plate is slid by a predetermined amount to match the positions of the dispersion holes of the dispersion plate and the seeding holes of the seeding plate, and at the same time a large amount of capsules are matted. Since seeding can be done on the top, labor can be saved and productivity is greatly improved. further,
There is a particularly remarkable effect that the supply of the capsules from the supply hopper and the recovery of the surplus capsules from the dispersion plate can be performed extremely smoothly. Further, according to the artificial seed sowing apparatus of the present invention, it is possible to sow the seeds into a predetermined sowing hole with an accuracy of almost 100%.
