Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a seeding device for use in a nursery box for seeds of ultrafine particles, such as seeds of Chinese cabbage, cabbage, or cauliflower.

(Prior art) When transplanting the above-mentioned vegetables to a field, fill a seedling raising box with many 5 cm square squares with bed soil, sow seeds on the bed soil and grow them, and then transplant the whole bed soil from the above-mentioned squares. The seedlings are pulled out and used as seedlings with soil, which are then transplanted using a transplanter.

The present invention relates to a seeding device for obtaining the above-mentioned seedlings with soil.

(Problems to be Solved by the Invention) When seeds are sown on the bed soil within the squares of the seedling box, sow 1 to 3 seeds at a time in the center of the square, and never sow them individually. If you sow in bulk, you will have to do a lot of thinning to get one (or two) plants.

However, if the seeds are large like radish,
It is not that difficult to make a device that can sow two or three seeds at a time, but since Chinese cabbage and other seeds are extremely fine particles, it is quite difficult.

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

(Means for solving the problem) In the present invention, a seed box 5 whose upper surface is horizontally opened is provided in the center of a horizontal table 3 that is long in the left and right direction, and seedling boxes 2 are placed on both left and right sides of the horizontal table 3. A placing section is formed, and one seedling growing box 2 is placed above the horizontal table 3.
A seed suction box 20 is provided that slides over the seed box 5 and moves horizontally in a reciprocating manner to above the other seedling box 2, and the seed suction box 20 sucks the seeds in the seed box 5 to fill the squares of the seedling box 2. In the seedling box sowing device configured to be able to sow seeds inside the seedling box, collection hoppers 18 and 18' are provided on both left and right sides of the seed box 5 to receive seeds spilled from the horizontal opening of the seed box 5, respectively, The upper surface openings of the recovery hoppers 18, 18' are located slightly lower than the upper surface of the seed box 5 as a seedling box seeding device.

(Example) An example of the present invention will be described with reference to the drawings.
is a frame, and 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 in such a length that the 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 raising box 2 can be easily slid and fed from the side. The seedling raising box 2 is made of synthetic resin, and has square cells 4 of about 5 cm in length and six horizontally.
Approximately 12 pieces (the number is arbitrary, but usually 1:2 vertically and horizontally)
(formed in ).

A predetermined width L is provided at the center portion of the horizontal table 3 described above.
A seed box 5 having a seed box 5 is provided. The seed box 5 has a special shape and is formed of a bottom member 7 that moves up and down within a vertical tube 6 that is rectangular when viewed from above.

The vertical cylinder 6 is formed by sheet metal processing a thin metal plate.
It is provided so that its upper end 8 always projects upward by α from the upper edge 9 of the seedling growing box 2 placed on the horizontal table 3.

The upper end 8 of the vertical tube 6 has an opening 10 cut completely horizontally, and at both left and right upper ends 8,
A rubber-like scraping piece 11 like an automobile wiper is fitted and attached. The scraping pieces 11 function to scrape off seeds, but they also serve as part of the seed box 5 because seeds are stored between the scraping pieces 11.

The upper edge 12 of the scraping piece 11 is formed to become gradually thinner, and the left and right scraping pieces 11 have exactly the same height X-X.
When viewed from the side, it is installed completely horizontally.

The vertical cylinder 6 is formed to have the same inner diameter (inner diameter) from beginning to end from the top to the bottom, and there is a bottom member 7 of the mold inside.
are tightly fitted. The upper end of the vertical piece 13 is fixed to the lower surface of the center of the bottom member 7.
A vertical rack gear 14 is attached to the holder.

A pinion 15 is meshed with the rack gear 14, and a shaft 16 of the pinion gear 15 protrudes forward.
A manual handle 17 is fixed. Therefore, when the manual handle 17 is manually rotated, the bottom member 7
moves up and down.

The upper opening formed by the inner surface of the vertical tube 6 and the upper surface of the bottom member 7 is a seed box 5 in which seeds are stored.
It becomes.

Hoppers 18 and 18' for collecting spilled seeds are attached to the left and right sides of the seed box 5, respectively.
Upper edge 19, 19' of collection hopper 18, 18'
is formed slightly lower than the upper end 8 of the vertical cylinder 6.

As described above, the seedling growing boxes 2 are placed symmetrically at the outer positions of the recovery hoppers 18 and 18'.

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, 2 placed on the left and right sides.

The size of the seed suction box 20 is about the same as the seedling raising box 2. The seed suction box 20 is a square box, and in particular, its bottom surface 21 is completely horizontal.
Further, the bottom surface 21 is formed of a high quality stainless steel plate so as not to be charged with static electricity.

The seed suction box 20 is moved laterally horizontally by a device to be described later. The seed suction box 20 moves horizontally from a position directly above one of the seedling raising boxes 2, and its bottom surface 21 rubs 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 and stop. The position of the bottom surface 21 of the seed suction box 20 is so formed that it always comes into contact with the scraping piece 11 and moves horizontally.

Arms 22, 22' for suspending the seed suction box 20
rollers 23, 23' are attached to the
The rollers 23, 23' roll on rails 24 provided horizontally on the frame 1 in the left-right direction. The seed suction box 20 is moved by a motor 25 attached directly or indirectly to the seed suction box 20.

The motor 25 is attached to a support member 26 attached to the top surface of the seed suction box 20.
The rotating shaft 27 is fixed so as to be the axis in the front-rear direction, and a pinion gear 28 is fixed to the rotating shaft 27, and the pinion gear 28 is meshed with a rack gear 29 in the left-right direction. When the main switch installed at the desired position of frame 1 is turned on, motor 2
5 is energized, the seed suction box 20 moves laterally, but in order to automatically stop it at a predetermined position, a switch 30,
30' is provided.

A contact plate 31 having a larger area than the seed suction box 20 is brought into contact with the upper surface of the seed suction box 20, and the contact plate 31 and the seed suction box 20 are fixed with screws 32.

The fact that the plate 31 is attached to the seed suction box 20 separately is also an ingenious point, and the reason for this is that various devices are attached to the plate 31, and the seed suction box 2
This is to make it convenient for attaching 0.

Both left and right ends of the plate 31 project laterally beyond the seed suction box 20, and leveling tools 33, 33' are attached to the projecting portions 32, 32', respectively. The leveling tools 33, 33' are also of a special construction, in which a coiled wire 35 is loosely fitted around the outer periphery of a metal round bar 34. Both the metal round rod 34 and the coiled wire 35 come into contact with the surface of the seeds in the seed box 5 to level the surface, 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. It is something.

Both ends of the metal round bar 34 are bent at right angles to form a bent portion 36, and the upper end of the bent portion 36 is inserted into the protruding portions 32, 32'' from below and fixed with screws.

On the bottom surface 21 of the seed suction box 20, suction holes are provided at positions corresponding to the centers of the squares 4 of the seedling raising box 2 for adsorbing only 2 to 3 (sometimes only 1 grain) ultrafine particles such as Chinese cabbage seeds. 37 is formed. Suction hole 37
is shaped so that the seed fits completely inside it.

There are two suction ports 3 on the top surface of the seed suction box 20.
8, 38' and a plurality of inlets 39... are opened. The two suction ports 38 and 38' are the numerous suction holes 3 bored in the bottom surface 21 of the seed suction box 20.
7, so that the seeds are evenly sucked with the same suction force, the openings are at the center of the left and right sides when viewed from the front and rear directions, but are opened at the centers of the front half and rear half of the halves when viewed from the left and right directions. ing.

The two 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 3 formed in the seed suction box 20
9 are lined up 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' at the front and rear are respectively attached to their upper surfaces.

The solenoids 43, 43' are fixed to protrusions 45, 45' that protrude upward from the contact plate 31, respectively, and the respective actuators 46, 43' of the solenoids 43, 43'
46', a connecting rod 47 is inserted, each valve 44 is attached to the connecting rod 47, and the solenoids 43, 4 are connected to each other.
The plurality of inlets 39 are formed to open simultaneously when electricity is applied to the inlet 3'.

The fact that the inflow ports 39 are simultaneously opened by the solenoids 43 and 43' is also a special feature, since this gives an impact to the seed suction box 20. The seeds described above contain a large amount of oil in their epidermis itself, so when they are strongly sucked and adsorbed, they are absorbed into the suction hole 37 not only by the suction force but also by the adhesive force of the oil. Because it adheres, it does not easily fall under its own weight, but solenoids 43 and 4
3' is expected to have the effect of not only opening the inlet 39, but also of separating seeds to which they are attached.

(effect) Next, we will discuss the effect.

Since the present invention has the above-described configuration, seeds such as Chinese cabbage, cabbage, or cauliflower are fully loaded into the seed box 5, and the bottom member 7 is moved slightly upward by slightly rotating the manual handle 17. Some of the seeds are allowed to spill over the wiper-like scrapers 11, 11 into the collection hoppers 18, 18'. In this state, when the seedling box 2 is placed on the horizontal stand 3 on the side where the seed suction box 20 is not located and the switch is turned on, the suction blower 41 rotates to suck air from each suction hole 37. become.

When the motor 25 is energized, the pinion gear 28 fixed to the rotating shaft 27 rotates to move the seed suction box 20 to the right, for example in FIG. 2. When the seed 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 the right end, and when the bottom surface 21 of the seed suction box 20 comes into sliding contact with the top surface of the seeds, the bottom surface 21
Seeds are absorbed by the suction hole 37 formed in the seedling box 2, and when the seed suction box 20 moves to the right, it hits the switch 30, the seed suction box 20 stops at the top of the seedling box 2, and the solenoid 4
3 and 43', the inlet port 39 is moved upward, and the seeds adsorbed in the suction hole 37 are removed from the seedling box 2.
It is to be dropped into square 4 of

In this case, the seed suction box 20 moves and the leveling tool 3
When the upper surface of the seeds in the seed box 5 is leveled with 3', the seeds are pushed and spilled, but the spilled seeds are
It is collected by the side collection hoppers 18, 18'.

(Effects) The present invention provides a seed box 5 whose upper surface is horizontally opened at the center of a horizontal table 3 that is long in the left and right direction, and forms a placement part for the seedling box 2 on both left and right sides of the horizontal table 3. , one seedling growing box 2 is placed above the horizontal table 3.
Slide over the seed box 5 from above to remove the other seedling box 2.
A seedling box seeding device is provided with a seed sucking box 20 that moves horizontally in a reciprocating manner to the top, and the seed sucking box 20 is configured to adsorb seeds in the seed box 5 and sow them in the squares of the seedling box 2. Therefore, seeds such as Chinese cabbage can be sown easily by simply moving the seed suction box 20 back and forth.

In addition, collection hoppers 18 and 18' are provided on the left and right sides of the seed box 5, respectively, to receive seeds spilled from the horizontal opening of the seed box 5, and the upper surface openings of the collection hoppers 18 and 18' are Since the sowing device for the seedling box is positioned slightly lower than the upper surface of the seed box 5, even if seeds are spilled, they can be reliably collected by the seed suction box 20 that moves back and forth, and the seed suction box 20 can prevent spilled seeds. Since it is moved horizontally back and forth, adsorption is reliable and uneven seeding does not occur.
