Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a seeding device for use in a seedling box for seedlings 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 and grow seeds on the bed soil, and grow the seedlings from the squares on the bed. The seeds are extracted 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 manufacture a device that can sow 1 to 3 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) Therefore, the present invention provides a seed box 5 whose upper surface is open at the center position of a horizontal table 3 on which a seedling raising box 2 can be placed, and a seed box 5 whose top surface is open at a position above the horizontal table 3. is provided with a seed suction box 20 that slides on the seed box 5 and moves laterally to above the seedling box 2, and sucks the seeds in the seed box 5 through suction holes 37 formed in the bottom surface 21 of the seed suction box 20. In the seedling box sowing device configured to be dropped into the center of the square 4 of the seedling box 2, the bottom surface 21 of the seed suction box 20 is provided with the seed suction box 2.
This is a seeding device for a seedling box, which is provided with a protrusion A that pushes and moves the seeds in the seed box 5 in the direction of the suction hole 37 when the seed box 5 slides on the seed box 5.

(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 to have a length that allows the seedling growing boxes 2 to be placed on both left and right sides.

The horizontal table 3 is formed almost flat except for the central part, and is formed so that the seedling 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 square cells 4, 5 vertically and 10 horizontally (the number is arbitrary, but usually the ratio is 1:2). ).

A seed box 5 having a predetermined width L in the left-right direction is provided at the center of the horizontal stand 3. Seed box 5
has a special shape, and is formed of a vertical tube 6 that is rectangular in shape with longer front and back sides when viewed from above, and a bottom member 7 that moves up and down within the vertical tube 6.

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 cylinder 6 has an opening 10 cut completely horizontally, and both upper ends 8 on the left and right sides thereof,
8 is fitted with a rubber-like scraping piece 11 like an automobile wiper. The scraping piece 11
Although they have the effect of scraping off seeds, they also serve as a part of the seed box 5 because they also store seeds between the scrapers 11.

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 X-X.
When viewed from the left and right sides, it is installed completely horizontally.

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 manual handle 17 is manually rotated, the bottom member 7 moves up and down.

A recess with an upward opening formed by the inner surface of the vertical cylinder 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 at the same height as the upper end 8 of the vertical tube 6.

The seedling growing boxes 2 are placed symmetrically on the outer sides of the collection hoppers 18, 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 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 seed suction box 20 is attached to the frame 1 so as to be movable laterally, but in this case, the bottom surface 21 of the box 20 is always attached at a height such that it can come into contact with the scraper 11 and move horizontally. That is, the seeds are adsorbed by the bottom surface 21 of the seed suction box 20, and in order to complete the adsorption effect, the bottom surface 21 is designed to directly rub the upper surface of the seeds.

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-back 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 attached to the frame 1. When the main switch installed at a desired position on the frame 1 is turned on, the motor 25 is energized and the seed suction box 20 is turned on.
switches 30, 30' for turning off the power to the motor 25 are provided on the frame 1 at the end of the horizontal movement of the seed suction box 20 in order to automatically stop it at a predetermined position.

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 32a.

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 because manufacturing becomes easier if 0 is attached.

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 upper surface of the seeds in the seed box 5 to level them, but at this time, the seeds are also moved to some extent in the left and right direction due to the 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.

As described above, the seed suction box 20 reciprocates from side to side on the seed box 5 to attract seeds with the suction hole 37 and sow them, so that the seeds in the seed box 5 below the suction hole 37 are transferred to other parts. The amount gradually decreases compared to . Of course, the coil wire 35 has the effect of compensating for this, but the projecting body A is provided separately from the coil wire 35, and this point is the gist of the present invention.

The protruding body A is formed by pasting a board shaped like a playing card diamond (diamond) on the bottom surface 21 of the seed suction box 20, or by pressing and expanding the bottom surface 21 of the seed suction box 20 by pressing. The protruding body A is attached between the suction hole 37 and the front and rear sides of the suction hole 37.

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 locations of the two suction ports 38 and 38' are specially designed so that the seeds can be uniformly sucked in from the numerous suction holes 37 formed in the bottom surface 21 of the seed suction box 20 with the same suction force. .

In other words, the dimensions of the seedling box are 1:2 horizontally, so when viewed from the front and rear, it is at the center of the left and right sides, but when viewed from the left and right, it is at the center of each of the front and rear half halves. Each is open.

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, 45' of the solenoids 43, 43'
A connecting rod 47 is connected to the connecting rod 46', each valve 44 is attached to the connecting rod 47, and the solenoids 43 and 4 are connected to each other.
The plurality of inlets 39 are formed to open simultaneously when electricity is applied to the inlet 3'.

When the inflow ports 39 are simultaneously opened by the solenoids 43 and 43', a shock is applied to the seed suction box 20. Seeds such as those mentioned above also have a
It contains a large amount of oil, so if it is strongly sucked into the suction hole 37, it will stick to the inside of the suction hole 37 not only by the suction force but also by the adhesive force of the oil, so it will not easily fall under its own weight.

In the embodiment of the present invention, the solenoid 43, 4 is completely caused to fall by its own weight by applying an impact.
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, the seedling raising box 2 is placed on the horizontal stand 3 on the side where the seed suction box 20 is not located, and when 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 seed suction box 20 to the right, for example in FIG. 2. When the seed suction box 20 moves to the right, the seeds in the seed box 5 are leveled by the leveling tool 33' attached to the right end, and the seeds are leveled on the bottom surface 21 of the seed suction box 20.
When the suction holes 37 formed in the bottom surface 21 slide against the upper surface of the seeds, the seeds are absorbed by the suction holes 37 formed in the bottom surface 21, and the seeds are completely fitted into each suction hole 37. Furthermore, seed inhalation box 2
0 moves to the right, the bottom surface 21 of the seed suction box 20 rubs the upper part of the scraping piece 11, and excess seeds are scraped off.

When the seed suction box 20 moves further to the right, the switch 3
0', the seed suction box 20 stops at the top of the seedling raising box 2, and the solenoids 43 and 43' are energized to open the inlet 39 with an impact, and the seeds adsorbed in the suction hole 37 are removed from the seedling raising box. It is to be dropped into the square 4 of No. 2.

Therefore, the seed suction box 20 reciprocates on the seed box 5 in the left-right direction, attracts the seeds to the suction hole 37, and sows them, so that the seeds in the seed box 5 below the suction hole 37 are The amount gradually decreases compared to the parts. However, in the present invention, since the protruding body A is provided between the suction hole 37 and the adjacent suction hole 37 in the front and back direction, when the seed suction box 20 moves, the protruding body A pushes the seeds in the direction of the suction hole 37. Since the seeds are pushed and moved, sufficient seeds are always moved below the suction hole 37 to ensure the suction effect.

(Effects) The present invention has the above-mentioned configuration and function, and in particular, a seed box 5 whose top surface is open is provided at the center position of the horizontal table 3 on which the seedling raising box 2 can be placed, and the seed box 5 is placed at a position above the horizontal table 3. is provided with a seed suction box 20 that slides on the seed box 5 and moves laterally to above the seedling box 2, and sucks the seeds in the seed box 5 through suction holes 37 formed in the bottom surface 21 of the seed suction box 20. Square 4 of the seedling raising box 2
In the seedling box sowing device configured to drop seedlings into the center of the seedling box, the bottom surface 21 of the seed suction box 20 is configured to drop the seeds in the seed box 5 when the seed suction box 20 slides on the seed box 5. Since the seedling box seeding device is provided with a protruding body A that is pushed and moved in the direction of the suction hole 37, the seed box 5 whose top surface is open at the center of the horizontal table 3 on which the seedling box 2 can be placed is provided. A seed suction box 20 that slides on the seed box 5 and moves horizontally to above the seedling box 2 is provided above the horizontal table 3, and a suction hole 37 formed in the bottom surface 21 of the seed suction box 20 is provided. With this configuration, the seeds in the seed box 5 are sucked and dropped into the center of the squares 4 of the seedling raising box 2, so that the seed suction box 20 is moved laterally and the seeds are sown in the center of the squares 4 of the seedling raising box 2. Can be done.

The bottom surface 21 of the seed suction box 20 is provided with a protrusion A that pushes and moves the seeds in the seed box 5 in the direction of the suction hole 37 when the seed suction box 20 slides on the seed box 5. Inhalation box 20
