Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for sowing seeds of ultrafine particles, such as seeds of Chinese cabbage, cabbage, or cauliflower.

When transplanting the vegetables to the field, first fill a seedling box with many 5 cm square squares with bed soil.
Seeds are sown on the bed soil to grow seedlings, and the bed soil is extracted from the square to form seedlings with soil, which is attached to a transplanter and transplanted.

The present invention relates to a seeding device for harvesting the seedlings with soil.

When sowing seeds on the bed soil within the squares of the seedling raising box, sow 2 to 3 seeds at a time in the center of each square, and never sow them separately. If you sow roses in bulk, you will have to do a lot of thinning work in order to end up with one (or two) plants.

However, if the seeds are large like daikon radish, it is not difficult to create a device that can sow two or three at a time, but seeds such as Chinese cabbage are extremely fine particles, so it takes a considerable amount of effort. accompanied by difficulty.

The present invention is a seeding device that has been carefully devised to achieve the above object.

In particular, the present invention provides a seed box with an open top surface in the vicinity of a horizontal table on which the seedling box is horizontally placed, and a seed box with an open top surface is placed above the horizontal table so that the seed box can be slid on the seed box and reach the top of the seedling box. A seedling box seeding device is provided with a suction box that moves laterally, and the suction box adsorbs seeds in the seed box and drops the seeds onto the squares of the seedling box. The gist of the present invention is to provide a seedling box seeding device in which a hopper is attached to catch the seeds spilled by the suction box, and an opening/closing shutter is opened at the bottom of the hopper to collect the spilled seeds.

To explain the overall structure, 1 is a frame. The frame 1 is provided with a horizontal stand 3 on which a seedling raising box 2 is placed. The height of the horizontal table 3 is the same as that of a general desk, and is set to such a level that a worker can easily hold and place the seedling box 2 thereon. The horizontal table 3 in the embodiment is
It is formed in such a length that a seedling growing box 2 can be placed on both sides by removing the central part. The horizontal table 3 is formed almost flat except for the central part, and is formed so that the seedling growing box 2 can be easily slid and fed from the front and rear directions. The seedling raising box 2 is made of synthetic resin, and has approximately 5 cm square cells 4, 5 vertically and 10 horizontally (the number is arbitrary, but the ratio of vertical and horizontal is usually 1:2). It is something that A seed box 5 having a predetermined width L in the left-right direction is provided at the center of the horizontal stand 3 described above. The seed box 5 has a special shape, and is formed of a vertical tube 6 that is rectangular in shape with longer front and rear sides when viewed from above, and a bottom member 7 that moves up and down within the tube 6. Vertical cylinder 6 formed by sheet metal processing of a thin metal plate
is a seedling growing box 2 whose upper end 8 is placed on a horizontal stand 3
It is provided so as to always protrude above the upper edge 9 by α. The upper end 8 of the vertical cylinder 6 is cut completely horizontally to form an opening 10, and a rubber-like scraper 11 like a car wiper is fitted and attached to both left and right upper ends 8. There is. The scraping piece 11
has the function of scraping off seeds, but it also stores seeds between the scrapers 11 or serves as a part of the seed box 5. The upper edge 12 of the scraping piece 11 is formed to be gradually thinner, and the left and right scraping pieces 11 have exactly the same height XX, and are installed completely horizontally when viewed from the left and right sides. The vertical tube 6 has the same dimensions from top to bottom, and a mold bottom member 7 is tightly fitted inside. The upper end of a vertical piece 13 is fixed to the lower surface of the center of the bottom member 7, and a vertical rack gear 14 is attached to the vertical piece 13. A pinion gear 15 meshes with the rack gear 14, and a shaft 16 of the pinion gear 15 projects forward, to which a manual handle 17 is fixed. Therefore, when the handle 17 is manually rotated, the bottom member 7 is moved up and down. A recess with an upward opening formed by the inner surface of the vertical tube 6 and the upper surface of the bottom member 7 becomes the seed box 5 in which the seeds are placed. Hoppers 18 and 18' for collecting spilled seeds are attached to the left and right sides of the seed box 5, respectively. When viewed from the left and right sides, the bottom walls 18a of the hoppers 18, 18' are sloped so that one side is high and the other side is low.
It protrudes forward from the horizontal base 3, and the shutter 18b is mounted there. The upper edges 19, 19' of the hoppers 18, 18' are formed at approximately the same height as the upper end 8 of the vertical cylinder 6. As mentioned above, seedling raising box 2
are placed symmetrically at the outer positions of the hoppers 18, 18', respectively. FIG. 1 shows a state in which the seedling growing boxes 2, 2 are placed, and FIG. 2 shows a state in which the seedling growing boxes 2, 2 are removed. A specially shaped seed suction box 20 is provided above one of the seedling growing boxes 2 placed on the left and right sides.
The size of the suction box 20 is generally the same as that of the seedling growing box 2. The suction box 20 is a square box, and in particular, its bottom surface 21 is completely horizontal. Further, the bottom surface 21 is not allowed to be charged with static electricity, and is made of a high-quality stainless steel plate. Inhalation box 20
is moved horizontally and laterally by a device to be described later. The suction box 20 moves horizontally from a position directly above one of the seedling-raising boxes 2, and its bottom surface 21 slides against the upper part of the wiper-like scraping piece 11, and further moves laterally, and then moves horizontally from a position directly above the other seedling-raising box 2. It reaches the top and stops. The position of the bottom surface 21 of the suction box 20 is so formed that it always comes into contact with the scraping piece 11 and moves horizontally. The suction box 20 has rollers 2 on the arms 22, 22' that suspend it.
3, 23' are attached, and rollers 23,
23' rolls on rails 24 provided horizontally on the frame 1 in the left-right direction. Inhalation box 20
is moved by a motor 25 attached directly or indirectly to the suction box 20. motor 25
is attached to a support member 26 attached to the upper surface of the suction box 20, and its shaft 27 is fixed so as to be the axis in the front-rear direction.A pinion gear 28 is fixed to the shaft 27, and the gear 28 is It meshes with the rack gear 29 in the left and right direction. When the main switch installed at a desired position on the frame 1 is turned on, the motor 25 is energized and the suction box 20 moves horizontally.
In order to automatically stop the suction box 20 at a predetermined position, switches 30, 30' for turning off the power to the motor 25 are provided at the abutment position of the suction box 20 in the advancing direction. A contact plate 31 which is larger in area than the suction box 20 is brought into contact with the upper surface of the suction box 20, and the contact plate 31 and the suction box 20 are fixed with screws 32. Another ingenious point is that the suction box 20 is fixed by abutting the backing plate 31 separately, and the reason for this is to make it easier to attach various devices to the backing plate 31. Both left and right ends of the contact plate 31 project laterally beyond the suction box 20, and leveling tools 33, 33' are attached to the projecting portions 32, 32', respectively. leveling tool 33,
33' is also of a special structure, and the metal round bar 34
A coil wire 35 is loosely fitted around the outer periphery of the coil wire 35.
Both the round rod 34 and the wire 35 touch the surface of the seeds in the seed box 5 and level them, but at this time, the seeds are moved in the front and back direction to some extent by rotation due to the contact resistance of the coiled wire 35. . Said round bar 3
4 has both ends bent at right angles to form a bent part 36, and the upper end of the bent part 36 is connected to the protruding parts 32 and 3.
Insert it into 2' from below and secure it with a screw. On the bottom surface 21 of the suction box 20, two ultrafine particles such as Chinese cabbage seeds are placed at positions corresponding to the centers of the squares 4 of the seedling raising box 2.
A suction hole 37 is formed that adsorbs only one to three grains (sometimes one grain). The suction hole 37 is formed so that the seeds can enter therein. Two suction ports 38, 38' and a plurality of inflow ports 39 are opened in the upper surface of the suction box 20. 2 suction ports 3
8 and 38' are specially designed so that the seeds can be sucked in evenly with the same suction force through the numerous suction holes 37 formed in the bottom surface 21 of the suction box 20. In other words, the dimensions of the seedling nursery box are in the ratio of 1:2 horizontally, so when viewed from the front and back direction, it is the center of the left and right sides, but when viewed from the left and right, it is the center of each of the front and rear half halves. They are each open to the public. 2
The suction ports 38, 38' are connected by one suction tube 40 as shown in FIG. 4, and a bellows 42 connected to a suction blower 41 is connected to the center of the suction tube 40. A large number of inlets 39 formed in the suction box 20 are arranged in a straight line in the front and back direction, and valves 44 that are moved up and down by two solenoids 43 and 43' are attached to the upper surface of each inlet. The solenoids 43 and 43' are respectively fixed to protrusions 45 and 45' that protrude upward from the contact plate 31.
A connecting rod 47 is connected to each actuator 46, 46' of the solenoids 43, 43', and each valve 44 is connected to the connecting rod 47.
is installed and the solenoids 43, 43' are energized, the plurality of inlets 39 are formed to open simultaneously. Connect the inlet 39 to the solenoid 4
3 and 43' at the same time is also a special feature, since it gives an impact to the suction box 20. Seeds like the ones mentioned above contain a large amount of oil in their epidermis, so if you strongly suck them up, they will not only stick with the suction force but also with the adhesive force of the oil, making it difficult to remove them. It will not fall under its own weight. The present inventor devised this point and applied an impact to cause the seeds to fall completely under their own weight.The solenoids 43, 43' not only open the inlet port 39, but also remove seeds with seeds attached to them. We are also looking forward to the effect of separating them.

Since the present invention has the above-described structure, the seed box 5 is filled with seeds such as Chinese cabbage, cabbage, and cauliflower, and the manual handle 17 is slightly rotated to move the bottom member 7 slightly upward. A portion of the liquid is allowed to spill over the wiper-shaped scrapers 11, 11 and into the hoppers 18, 18', and in this state, place the seedling box 2 on the horizontal table 3 on the side where the suction box 20 is not located.
When the suction blower 41 is placed and the switch is turned on, the suction blower 41 rotates and sucks air from each suction hole 37.

When the motor 25 is energized, the pinion gear 28 fixed to the rotating shaft 27 rotates to move the suction box 20 to the right, as shown in FIG. 2, for example. When the suction box 20 moves to the right, the top surface of the seeds in the seed box 5 is leveled by the leveling tool 33' attached to its tip, and when the bottom surface 21 of the suction box 20 comes into sliding contact with the top surface of the seeds, a smooth surface is formed on the bottom surface. suction hole 3
7 to suck up the seeds, then move further to the right, switch 3
0, the suction box 20 stops above the seedling box 2, and the solenoids 43 and 43' are energized, causing the valve 44 that closes the inlet 39 to move upward, and the suction box 20 is attracted to the suction hole 37. The seedlings are dropped into the squares 4 of the seedling raising box 2. Then, as the number of seeds in the seed box 5 decreases, the manual handle 17 is rotated to move the bottom member 7 upward.
The seeds inside can be absorbed one after another and sown until they are exhausted.

The embodiment of the present invention is as described above. Since the hoppers 18 and 18' are provided on both sides of the seed box 5, all spilled seeds can be collected in the hoppers 18 and 18', and the bottom of the hopper 18 wall 18
Since one side of the hopper a is high and the other side is sloped low, and an opening/closing shutter 18b is attached to the lower part, the seeds that have fallen into the hopper 18 are collected by the shutter 18.
This has the effect that it can be easily taken out by opening b.
