Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sowing tool.

[0002]

2. Description of the Related Art When planting seedlings such as vegetables is performed by a transplanter, seedlings are generally grown in each seedling pot in a resin seedling tray in which a plurality of seedling pots are arranged vertically and horizontally. The seedling tray is set on a transplanter to enable continuous supply of seedlings.

[0003] Therefore, in such a seedling tray,
Put a predetermined amount of bed soil into each seedling pot, sow one or a predetermined number of seeds, sprinkle water, and then, if necessary, put the seedling tray into the house for germination. You have to wait for it. In addition, if a large-scale farmer can set up a dedicated sowing plant and the like, it is possible to automate most of these operations. Is mostly by hand.

[0004]

When raising seedlings on a seedling tray by hand, the seeding operation is the most troublesome of the operations and occupies a large weight in time. In addition, this seeding work has a dislike of inferior accuracy, and when individual seedling pots contain a predetermined number or more of seeds, thinning and inspection of seedlings are required after germination in each seedling pot, and conversely, When a seedling-raising pot in which seeds cannot enter is generated, the yield related to seedling-raising and transplantation work is inferior, and the subsequent vegetable harvest may be adversely affected.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a sowing apparatus that can easily, quickly and accurately sow seedling trays and the like by hand. I do.

[0006]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the seeding device according to the present invention has an inner case and an outer case slidably fitted to the inner case, and the inner case and the outer case are brought into surface contact with each other when sliding. A plurality of seed contact holes for allowing a predetermined number of seeds to pass therethrough are formed at predetermined intervals in the sliding contact wall of the inner case, and a sliding contact wall of the outer case is formed in the sliding contact wall of the outer case. There are formed a plurality of seed drop holes that individually switch from a non-coincidence state to a coincidence state with respect to various embedding holes of the inner case before and after sliding on the inner case.

In such a configuration, first, the relative sliding positional relationship between the inner case and the outer case is set so that the seed insertion hole of the inner case and the seed drop hole of the outer case do not match. . Therefore, in the inside of the inner case, the various holes are in a concave state in which the bottom side is closed by the sliding contact wall of the outer case. Then, when seeds are put into the inner case in this state and the inner and outer cases are shaken, a predetermined number of seeds are prepared for loading into the individual seed holes.

Therefore, when the inner case and the outer case are slid relative to each other, the seed hole of the inner case coincides with the seed drop hole of the outer case, and a predetermined number of seeds prepared for loading into the seed hole are removed. It falls according to the formation interval of the seed hole. Therefore, if this seeding device is used, a plurality of seedling raising pots are arranged on a seedling tray arranged in rows and columns.
Seeding to each seedling pot is simple, quick and reliable.

[0009] If the seed case is provided at opposite ends of the case with respect to the inner case, the inner case and the outer case are tilted so that the seed cases on both sides of the inner case alternately have a height relationship. The operation can be repeated. Since such an operation is extremely simple and simple, not only is it easy to load the seeds into the various pits, but also the surplus seeds after all the seed pits are filled can be tilted. It can be collected in the seed pool below.

Therefore, there is an advantage that the number of seeds falling can be assured when the seed hole in the inner case is aligned with the seed drop hole in the outer case. The inner case and the outer case may each have a dish shape or a box shape,
If it is made into a round or square cylindrical shape and the seed hole and the seed drop hole are formed in a single row along the axial direction of the tube, it becomes easy to hold and excellent in operability. Also, if the inner case and the outer case are urged by a return spring to self-hold the state before sliding relative to each other, that is, the state where the seed hole and the seed drop hole do not match, the seeding operation is performed. Has the advantage that it becomes easier.

When this seeding tool is used in the above-mentioned seedling tray, it is a matter of course that the seed putting hole and the seed falling hole are set at intervals corresponding to the arrangement pitch of the seedling raising pots. On the other hand, if a position setting member for the seedling tray is provided, the seeding operation can be further facilitated, speeded up, and assured.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of a seeding implement 1 according to the present invention. This seed sowing tool 1 has a cylindrical inner case 2 having a hollow circular cross section.
And an outer case 3 slidably fitted to the inner case 2.

The outer case 3 is also formed in a cylindrical shape having a hollow circular cross section, and its inner diameter is formed so as to be slidable with the outer diameter of the inner case 2. Therefore, the outer peripheral surface of the inner case 2 and the inner peripheral surface of the outer case 3 form sliding contact walls 2a and 3a that maintain a surface contact state when sliding with each other. A part of the sliding contact surface 3a of the outer case 3 is provided with a detent ridge 5 projecting inward in the radial direction, and a part of the sliding contact surface 2a of the inner case 2 is provided with a detent. An engagement groove 6 into which the ridge 5 is fitted is formed. Therefore, relative rotation between the inner case 2 and the outer case 3 is prevented.

Then, of the sliding contact wall 2a of the inner case 2,
A plurality of seed holes 8 are formed at predetermined intervals in one row along the cylinder axis direction. Each seed hole 8 has an inner diameter that allows a predetermined number (one or more) of seeds W to pass through. The mutual interval between the seed placement holes 8 is formed in accordance with the arrangement pitch at which the seedling pots P are provided in the seedling tray T. The number of the seed placement holes 8 is determined by the seedling placement pot P in the width direction of the seedling tray T. And the same number as that of

On the other hand, a plurality of seed drop holes 9 are formed in the sliding wall 3a of the outer case 3 in a row in the axial direction of the cylinder facing the seed hole 8 of the inner case 2. The interval between the seed drop holes 9 is the same as the interval between the seed drop holes 8, and the number of the seed drop holes 9 is the same as the number of the seed drop holes 8. The inner diameter of the seed drop hole 9 is the same as or slightly larger than the inner diameter of the seed hole 8.

The inner case 2 is longer than the outer case 3 and projects to both ends of the outer case 3. And
One end of the inner case 2 is provided with a spring support 12
The outer case 3 is provided with a spring support 13 at the end of the outer case 3 on the same side, and a return spring 14 such as a coil spring is provided between the spring supports 12 and 13.
Is fitted.

The return spring 14 allows the inner case 2 and the outer case 3 to be self-maintained such that the seed hole 8 and the seed drop hole 9 do not coincide with each other. When the inner case 2 and the outer case 3 are slid relative to each other in a direction against the elastic force, the seed hole 8 and the seed drop hole 9 can be aligned.

That is, before and after sliding of the inner case 2 and the outer case 3, the seed hole 8 and the seed drop hole 9 can be switched between a mismatched state and a matched state. Preferably, the return spring 14 is covered with a telescopic cover 15 having a bellows structure, which prevents the return spring 14 from being rusted or clogged by soil or water. it can.

At both ends of the inner case 2, caps 18 are externally fitted, and one or both of them are
It is removable. Although not shown in the figure, the structure for making it detachable includes one using a fitting dimensional difference, one using an engagement structure using a dowel or the like, one using a screw-fitting relationship, and other engagement. It is possible to adopt one having a structure or the like.

The inside of the cap 18 is slightly larger in diameter than the inner diameter of the inner case 2, thereby forming a seed reservoir 20. One end of the outer case 3 is provided with a position setting member 22 that projects toward the surface where the seed drop hole 9 is provided. This position setting member 22
Has a contact portion 23 which can be engaged with one side edge in the width direction of the seedling tray T and a spacer portion 24 which comes into contact with the upper surface of the seedling tray T. The positioning of the seed drop hole 9 with respect to the seedling raising pot P) and the positioning in the height direction (that is, the degree of proximity) can be performed.

It is preferable to provide a spacer 25 protruding in the same direction as the position setting member 22 also at the other end of the outer case 3 since the degree of parallelism when approaching the seedling tray T can be maintained. . Next, the use situation of the seeding implement 1 having such a configuration will be described. First, one cap 18 of the inner case 2 is removed, a predetermined amount of the seed W is put into the inner case 2 from here, and the cap 18 is fitted back.

Then, a rocking operation is performed on the seed sowing device 1 such that the seed collecting portions 20 on both sides of the inner case 2 are alternately tilted two or three times so as to have a height relationship.
As a result, in the inner case 2, as shown in FIG. 4, the seeds W of a number (one in the illustrated example) corresponding to the inner diameter are loaded into the various nesting holes 8. After all the seed holes 8 have been loaded with the seed W, the excess seed W remaining in the inner case 2 is collected in the seed storage section 20 which was finally set to the lower side of the slope. Will be done.

Therefore, the position setting section 22 is engaged and placed in a predetermined state on one side edge of the upper surface of the seedling tray T in a state in which the bed soil is put into the seedling raising pot P, and The spacer 25 is placed on the upper surface of the edge. As a result, all the seed drop holes 9 of the outer case 3 are positioned at substantially the center positions of all the seedling pots P in the horizontal row of the seedling tray T.

Next, while preventing the outer case 3 from moving relative to the seedling tray T, the return spring 1
The return spring 14 is compressed by pushing the one end (cap 18) on the fourth side. Thereby, as shown in FIG. 5, the seed drop hole 9 of the outer case 3 matches the seed drop hole 8 of the inner case 2, and the seed W loaded in the seed drop hole 8 After that, it falls to each seedling raising pot P of the seedling tray T.

Thereafter, when the state where one end of the inner case 2 is pushed in is released, the inner case 2 is slid and returned to the original state by the return spring 14, so that the seed insertion hole 8 and the seed drop hole 9 are separated. A mismatch state is returned to the first stage. Such an operation may be repeated by the number of rows of the seedling raising pots P in the longitudinal direction of the seedling tray T.

FIG. 6 shows a second embodiment of the seeding implement 1 according to the present invention. This second embodiment is similar to the first embodiment.
The difference from the embodiment is that the position setting member 22 is provided for the inner case 2. Therefore, in the second embodiment, when the position setting portion 22 is engaged and placed in a predetermined state on one side edge of the seedling tray T in the width direction, all the seed insertion holes 8 of the inner case 2 are set in the seedling hole 8. It will be positioned at the center position of all the seedling pots P in the horizontal row of the tray T.

Therefore, as a subsequent operation, the outer case 3 is slid in a direction to compress the return spring 14 while keeping the inner case 2 from moving with respect to the seedling tray T. The seed drop hole 9 of the outer case 3 matches the seed drop hole 8 of the case 2, and the seed W loaded in the seed drop hole 8 falls through the seed drop hole 9.

The position setting member 22 has an attachment part 22a to the inner case 2 which also functions as a spring receiver 12 for receiving the return spring 14 on the inner case 2 side. By the way, the present invention is not limited to the above embodiments. For example, the length of the inner case 2, the mutual interval and the number of the seed holes 8, and the outer case 3
The length and the mutual interval and the number of the seed drop holes 9 can be formed to match the longitudinal direction of the seedling tray T.

Further, these are not limited to correspond to the seedling tray T, and can be formed to correspond to other various pallets and containers.
Therefore, naturally, as seed W put in the inner case 2,
The present invention is not limited to vegetable seeds, but is applicable when sowing seeds such as flowers. The relative sliding between the inner case 2 and the outer case 3 is not limited to linear sliding along the cylinder axis, but may be rotation about the cylinder axis.

By forming the inner case 2 and the outer case 3 into a square cylindrical shape, it is possible to omit the rotation stopping structure between them. The inner case 2 and the outer case 3
Can be a dish shape or a box shape, and the seed putting hole 8 and the seed falling hole 9 can be respectively arranged in a plurality of rows.

[0031]

As is apparent from the above description, in the seeding apparatus according to the present invention, the inner case and the outer case fitted to the outer case are slid relatively to each other, so that the seed receiving hole of the inner case is formed. And the seed drop hole of the outer case is switched from a mismatched state to a matched state, so that a predetermined number of seeds put into the inner case can be dropped and supplied according to the formation pitch of the seed insertion hole and the seed drop hole. For example, manual sowing of seedling pots in a seedling tray can be performed easily, quickly and accurately.

If seed storage portions are provided at both ends of the inner case, when the inner and outer cases are shaken so that the seed storage portions on both sides alternately have a height relationship, seeds are loaded into various nesting holes. This is convenient because surplus seeds can be collected in the seed reservoir. If the inner case and the outer case are formed in a cylindrical shape, and the seed receiving hole and the seed drop hole are formed in a single row along the axial direction of the tube, it becomes easy to hold and excellent in operability. In addition, if a return spring is provided between the inner case and the outer case, an operation for returning the two cases to the original positions in one operation is not required, and speeding up and labor saving can be achieved.

If the position setting member is provided in the inner case or the outer case, the positioning with respect to the seedling tray or the like can be easily performed, the workability is improved, and the speed and reliability are further improved. .
