Description

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

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, the germination rate of seeds varies considerably depending on their quality. For example, extremely high quality seeds are omitted.
The germination rate is 100%, while the germination rate of seeds that are not very good is only around 70%. Therefore,
Depending on the condition of the seeds, it is decided whether to sow only one seed or three at a time.

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

To explain the figures, FIGS. 1 to 7 relate to the overall structure, and numeral 1 indicates 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 is formed to have a length that allows the seedling growing box 2 to be placed on both sides of the horizontal table except for the central portion. 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 is formed of a vertical cylinder 6 which has a rectangular shape with longer front and rear sides when viewed from above, and a bottom member 7 that moves up and down within the vertical cylinder 6. The vertical tube 6 is provided so that its upper end 8 always projects upward by α from the upper edge 9 of the seedling raising box 2 placed on the horizontal stand 3. The upper end 8 of the vertical tube 6 has a completely horizontal opening 10, and rubber-like scrapers 11, such as car wipers, are attached to both left and right upper ends 8.
The scraping piece 11 functions to scrape off seeds. The upper edge 12 of the scraping piece 11 is gradually made thinner, and the left and right scraping pieces 11 have exactly the same height XX. A mold bottom member 7 is tightly fitted inside the vertical tube 6. A vertical piece 13 is provided on the lower surface of the center of the bottom member 7.
The upper end of the vertical piece 13 is fixed, and a vertical rack gear 14 is attached to the vertical piece 13. A pinion gear 15 meshes with the rack gear 14,
A shaft 16 of the pinion gear 15 projects forward, and a manual handle 17 is fixed thereto. 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 serves as a seed box 5 in which seeds are placed. Said seed box 5
Hoppers 18 and 18' for collecting spilled seeds are attached to the left and right sides of the container, respectively. 19, 19' are the upper edges of the hoppers 18, 18'. Seedling raising box 2 is
They are placed symmetrically at the outer positions of the hoppers 18, 18', respectively. Figure 1 shows the seedling raising boxes 2, 2 placed on it, and Figure 2 shows the seedling raising boxes 2, 2 placed there.
Shown with removed. A specially shaped seed suction box 20 is provided above one of the seedling growing boxes 2, 2 placed on the left and right sides. The size of the suction box 20 is about 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. Moreover, the bottom surface 21 is
It is not allowed to be charged with static electricity and is made of high quality stainless steel plate. The suction box 20 moves horizontally from a position directly above one of the seedling growing boxes 2, slides on the top of the wiper-like scraper 11, moves further laterally, and stops when it reaches right above the other seedling growing box 2. do. Inhalation box 2
The position of the bottom surface 21 of 0 is so formed that it always comes into contact with the scraping piece 11 and moves horizontally. The suction box 20 has rollers 23 and 23' attached to arms 22 and 22' that suspend it, and the rollers 23 and 23' roll on rails 24 provided horizontally on the frame 1 in the left and right direction. move. The suction box 20 is moved by a motor 25 attached directly or indirectly to the suction box 20. motor 2
5 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 mesh with the left and right rack gears 29. 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 laterally. Motor 25 at the end position
Switches 30, 30' are provided to turn off the electricity. 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. Both left and right ends of the plate 31 project laterally beyond the suction box 20, and leveling tools 33, 33' are attached to the projecting portions 32', 32'', respectively. Leveling tools 33, 3
3' also has a special structure, in which a coil wire 35 is loosely fitted around the outer periphery of a metal round bar 34. 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 also moved in the front and back direction to some extent by rotation due to the contact resistance of the coiled wire 35. be. 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.
2" from below and fix it with screws. On the bottom surface 21 of the suction box 20, two ultrafine particles such as Chinese cabbage seeds are placed in the center of each cell 4 of the seedling raising box 2.
A suction hole 37 is formed that absorbs 3 to 3 particles. The suction hole 37 is formed so that a seed fits therein. Two suction ports 38, 38' and a plurality of inflow ports 39 are opened in the upper surface of the suction box 20. The locations of the two suction ports 38 and 38' are specially designed so that the seeds can be sucked in evenly with the same suction force from 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 at a 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. Two suction ports 38,3
8' 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 inflow ports 39 formed in the suction box 20 are lined up in a straight line in the front and back direction, and two solenoids 4 in the front and rear are installed on the top surface.
3 and 43' are respectively attached to valves 44 that move up and down. The solenoids 43, 43' are provided with protrusions 45, 4 that protrude upward from the contact plate 31.
5' respectively, and the solenoids 43,
Hang a connecting rod 47 around each actuator 46, 46' of 43', and attach each valve 44 to the connecting rod 47.
When the solenoids 43, 43' are energized, the plurality of inflow ports 39 are formed to open simultaneously. The fact that the inlet ports 39 are simultaneously opened by the solenoids 43 and 43' is also a special feature, since this 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. FIGS. 8 to 10 specifically show an apparatus capable of adjusting the seeding rate. Three suction holes 37 are opened in rows in the front and rear direction. As shown in FIG. 9, one suction hole absorbs and fits only one grain. Bottom surface 21
An adjustment plate 49 is provided on the upper surface of the member so as to be slidable in the front-rear direction, and has a long hole 48 corresponding to the length of three suction holes 37. The adjustment plate 49 may be a single piece or a knotted blade-like piece as shown in FIG. 10.

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, and move further to the right to switch to 30
The suction box 20 stops at the top of the seedling box 2, and the solenoids 43 and 43' are energized to open the inlet 3.
9 is moved upward with an impact to cause the seeds adsorbed in the suction holes 37 to fall into the squares 4 of the seedling raising box 2. Then, when the manual handle 17 is rotated to move the bottom member 7 upward as the number of seeds in the seed box 5 decreases, the seeds in the seed box 5 can be successively attracted and sown until they are exhausted.

At this time, the adjustment plate 4
By moving and adjusting 9 as shown in FIG. 9 A, B, or C, the number of seeds can be freely adjusted between 1 and 3 seeds.

The present invention has the above-described structure and operation, and the gist of the present invention is that the amount of seeds to be sown in the squares 4 of the seedling raising box 2 can be adjusted. The effect can be achieved by spot sowing or three-seed sowing.
