Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual spotting machine for seeding seeds in fields, ridges and the like.

[0002]

2. Description of the Related Art A machine for surely sowing seeds one by one on a field surface or a furrow was presented at the theme of "Study on film multi-cultivating seeder" at the 50th convention of the Japan Society of Agricultural Machinery. Technology is known (Heisei 3
(See the abstract of the lecture in April, 2014).

This film multi-cultivating seeder comprises a seeder main body equipped with wheels, a seed hopper, a seed discharge shutter,
Equipped with a feeding section, wheel drive section, computer, etc.,
The surface of the field or ridges are directly driven to drive the seeds in the seed hopper onto the seeding shutter by the eye plate which is driven to rotate by the stepping motor. A hole detecting sensor detects a hole provided in the mulch and opens the seed discharging shutter to seed the seed.

[0004]

However, this seeding machine is large, and therefore suitable for sowing in a large-scale field, but for small-scale sowing such as sowing in a greenhouse. Not suitable. It was virtually impossible to sow this device into a container such as a planter, and it was also impossible to sow into a seedling box placed on a shelf. It is an object of the present invention to provide a point seeder which solves such problems, that is, which is easy and reliable, and which can be applied to sowing in a seedling box on a shelf or a planter. .

[0005]

In order to solve the above-mentioned problems, the point seeding machine of the present invention conveys reciprocally between the seed storing position and the seed discharging position by operating the handle. The body has a through-hole that penetrates the top and bottom and only one seed is stored. When the carrier is at the seed storage position, it is above the through-hole of the carrier and the seed is placed in the through-hole. And a guide tube for guiding and dropping the seed stored in the through hole to the sowing position, which is below the through hole when the carrier is at the seed discharging position.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION If the manual spotting machine of the present invention has a guide groove for guiding the seeds inside the hopper into the through holes at the upper part of the carrier, the seeds inside the hoppers will surely penetrate through the through holes. Since it is housed in the container, the seeding reliability is improved, which is desirable. The shape of the guide groove is appropriately selected so that the above effect can be obtained.

Here, it is necessary that the shape of the through hole is a size capable of accommodating only one seed. If the shape of the through-holes is too large, it may not be possible to surely seed each one, or it may not move during the operation of the handle. If it is too small, it cannot be seeded.

[0008] In order to surely sow the seeds, it is desirable that the seeds to be sowed are of uniform size and spherical seeds. If the seeds are coated seeds, it is possible to satisfy these conditions regardless of the type of plant and it is possible to surely perform point sowing, which is desirable. Here, as the coated seeds, gel-coated seeds and the like can be suitably used in addition to ordinary coated seeds.

Since the gel-coated seed improves the germination rate and the germination rate by the water content of the gel-coated layer, the size thereof is usually as large as 5 to 15 mm. If a seeding machine for sowing a plurality of seeds at the same time, such as a conventional manual sowing machine, is to be applied to the spot seeding of the gel-coated seeds, it will be too large and heavy to be put into practical use. However, the manual spotting machine of the present invention does not have such drawbacks, is easy to handle, and is extremely easy to use.

In the manual spotting machine of the present invention, the seeding is performed by reciprocating movement between the seed storing position and the seed discharging position of the carrier. In order to facilitate the operation of the handle for operating this, a spring or rubber is used. It may have a mechanism such that the handle automatically returns. The reciprocating movement of the carrier may be linear reciprocating movement or rotational reciprocating movement.

Next, a manual spotting machine according to the present invention will be described with reference to the drawings. FIG. 1 shows an example of a manual spotting machine according to the present invention. (A) is a front view and (b) is a side view. Reference numeral 1 in the drawing is a main body, and a rod portion 2 is incorporated therein as a carrier. The rod portion 2 slides in the main body portion 1 between a seed storage position and a seed discharge position. A handle 2b is attached to the rod portion 2 for the sliding operation. As shown in FIG. 2, the handle 2b is fitted in the handle groove 2a provided in the rod portion 2 and is screwed from the back surface.

A hopper portion 3 for storing seeds is provided on the upper portion of the main body 1, and an induction cylinder 4 for guiding and dropping the seeds to a target location is provided on the lower portion. The hopper portion 3 has a gentle inclination so that the seeds to be stored therein are guided to the through hole 2d of the rod portion 2 at the seed storage position, so that the seeds are prevented from being clogged.

On the other hand, the guide tube 4 is provided with a collar portion 4a, which comes into contact with the surface of the field during sowing.
Seeds are sown at a predetermined depth. Further, the assembly of the main body 1, the connection between the main body 1 and the hopper 3, or the connection between the main body 1 and the guide cylinder 4 are formed by screws as shown in FIGS. 1 (a) and 1 (b). Therefore, it can be disassembled as needed, and the cleaning or maintenance of the inside is easy.

Next, the operation of this manual spotting machine will be described with reference to FIG. FIG. 3A is a cross-sectional view taken along the line AA in FIG. Gel-coated seeds are stored inside the hopper 3. The rod portion 2 built in the main body portion 1 is in the seed storage position in this figure. This is part 2
Gel-covered seeds (1 grain) in the storage hole 2d penetrating vertically
Is stored. The shape of the through hole 2d is such that only one gel-coated seed is stored.

The rod portion 2 slides in the direction of the arrow in the figure by operating the handle 2b. Through hole 2 in the sliding process
The seeds other than the gel-covered seeds (one grain) already stored in d are excluded by the partition plate 1a. FIG. 3B shows a cross section of the main part after the slide movement. In this figure, the rod portion 2 is at the seed discharging position, the through hole 2d coincides with the hole portion provided in the main body 1, and the stored gel-coated seed falls inside the guide tube 4 and the guide tube 4 And seeded in the field. After the gel-covered seeds stored in the through hole 2d have been sown in this way, the rod portion 2 is returned to the seed storage position again by the operation of the handle 2b, and one gel-coated seed stored in the hopper portion 3 is It is supplied to the through hole 2d.

As shown in FIG. 4 (a cross-sectional view taken along the line BB in FIG. 1B), the rod portion 2 has a guide groove 2c, which allows the gel-coated seeds stored in the hopper portion 3 to be roded. It is arranged so as to be close to the central portion of the portion 2 and be surely accommodated in the through hole 2d of the rod portion 2. Further, as shown in FIG. 2, the partition plate 1a is provided with a convex portion having a shape corresponding to the concave portion of the guide groove 2c in the upper portion of the rod portion 2, and there is almost no gap between them. Therefore, the gel-covered seeds other than those housed in the through holes 2d are excluded by the partition plate 1a during the operation of the rod portion 2, and therefore there is no risk of being caught in the gap and damaged.

With the structure described above, it is easy to say that the guide tube 4 is applied to the seeding target location (for example, the hole of the mulch), inserted into the soil until the collar 4a comes into contact, and then the handle 2b is operated. The seeding operation can be continuously performed by repeating such operations. It should be noted that such a handle operation can be easily performed even when sowing the soil (planter or the like) in a place higher than the ground by a shelf or the like. In this case, the work can be facilitated by replacing the guide tube 4 with a short one as necessary. In addition, this manual seeder is easy to reduce in weight, and even if a large number of heavy seeds such as gel-coated seeds are stored in the hopper for operation, the point sowing work can be performed easily and efficiently.

[0018]

INDUSTRIAL APPLICABILITY The manual spotting machine according to the present invention is lightweight and convenient, and can be applied to seeding in a mulch hole, a greenhouse, a seedling box on a shelf or a planter. In addition, you can know the number of seeds because you can surely sow one by one,
This seeding number can be associated with the emergence rate or the yield, which facilitates production planning. Alternatively, it becomes possible to predict the yield from the time of seeding.
