Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an improvement of a seeding device suitable for sowing two rows of rosewood.

[Conventional technology and problems]

In general, for example, the sowing means for a seedling nursery box is a so-called spline-shaped seeding roll in which multiple grooves are formed at equal intervals on the outer periphery in the longitudinal direction, and a device that applies mW to the paddy in the hopper while it is accommodated in the grooves. There is. With this type of equipment, paddy is sometimes sown in piles on the bed soil.
This uneven sowing not only results in weak seedlings, but also leaves areas with no seedlings.

This causes, when rice is automatically transplanted using a rice transplanter, a portion where rice is not transplanted due to a lack of seedlings, or a portion where IE is not planted enough to have a predetermined number of plants, which has a negative impact on the harvest. Therefore, conventionally, such large stocks were checked manually.

There were inconveniences such as having to replant the seedlings.

For this reason, there is a need for a seeding device that can raise strong seedlings without producing large plants. This requires uniform para-sowing and uniform row-sowing in the seedling box, but as a means to satisfy these conditions,
Publication No. 813 and the like have been proposed. This device has a number of rows of recesses at appropriate intervals on the surface of the sowing roll, into which the rice grains are inserted, but there is no guarantee that the sprouted paddy grains will be accommodated in all the recesses and transported. The problem of similar uneven seeding has not yet been solved.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it solves the problems of the conventional technology by simple and rational means, and ensures the paddy harvest by using the elasticity of the sowing roll, regardless of the sowing in two rows. The purpose of the present invention is to provide a device that can evenly capture rice grains, use this elasticity to reliably layer rice on the bed soil, and raise seedlings without missing plants.

[Configuration of the Invention] The configuration of the present invention, which solves the problems of the prior art, is to supply paddy stored in a hopper between a rotating seeding roll and a roll guide, release the paddy at the bottom of the seeding roll, and transfer the paddy to a seedling nursery box. In the apparatus for sowing seeds on a soil bed, the surface layer of the seeding roll is formed of a flexible and elastic material.

〔Example〕

The details of the embodiments will be explained with reference to the drawings.

FIG. 1 is a partially cutaway front view, and FIG. 2 is a partially cutaway perspective view of the main part when using a paddy guide plate for bulk sowing.

FIG. 3 is a partially cutaway perspective view of the main part when using the paddy guide plate for row sowing.

Reference numeral 1 denotes a machine frame installed on the floor, and at the top of one side of the machine frame 1 is provided a paddy hopper 3 having a spline-structured paddy pay-out roll 2 provided at the lower end opening. Below the hopper 3, there is disposed a reading guide plate 4 which receives the paddy fed out from the hopper 3 and has a substantially horizontal attitude. This reading guide plate 4 is rotatably supported by a downward stay on the machine frame 1 in a detachable and replaceable manner so that it can move in an arc shape along the conveying direction of the seedling box 5.
Specifically, on the upper side of the seedling raising box 5 in the transport direction, there is a reading guide plate 4.
A vibrating device 6 such as a vibrator that vibrates along the transport direction of the seedling box 5 is connected.

7 is an elastic layer 7 made of a flexible elastic material such as sponge as a surface layer.
This seeding roll 7 is a relatively large diameter seeding roll with a
The lower side end of the reading guide plate 4, more specifically, the paddy supply end, should be faced near the top of the seeding roll 7, and the half circumference on the lower side from near the top of this sowing roll 7 to near the bottom end should face the side of the sowing roll 7. A semicircular roll guide 8 made of a rigid material and attached to the machine frame 1 is placed adjacent to the seeding roll 7.
It is arranged concentrically with the

In the figure, reference numeral 9 denotes a transfer roller for the seedling-raising box 5 horizontally suspended on the machine frame 1.

Figure 2 shows a reading guide plate 4 with a flat plate structure as a guide for sowing paddy in bulk.
Fig. 3 shows an example in which a reading guide plate 4b with a corrugated plate structure is used for row sowing of paddy, and both paddy guide plates 4a and 4b are replaced as appropriate depending on the purpose of sowing. It is something to do.

[For production]

Next, the seeding action will be explained based on the above embodiment.

The paddy stored in the hopper 3 is uniformly dropped onto the paddy guide plate 4 by the feed roll 2 rotating in the direction of the arrow in FIG. The paddy supplied onto the reading guide plate 4 is sent in an orderly direction to the lower side by the arc-shaped vibration action of the reading guide plate 4 vibrated by the vibration device 6, and is continuously sent from the feeding end of the reading guide plate 4. The paddy to be sent out is interposed between the sowing roll 7 and the upper end of the roll guide 8 near the top of the sowing roll 7. At this time, since the surface layer of the seeding roll 7 is made of a flexible elastic material, the paddy bites into the elastic layer 7a of the seeding roll 7 as shown in the figure, and is held between the roll guide 8 without moving. conveyed in the direction of the arrow.

When the paddy reaches below the sowing roll 7, passes the lower end of the roll guide 8, and is released from the pressing action of the roll guide 8, it is properly released and dropped by the restoring force of the elastic layer 7a of the sowing roll 7, Seeds are evenly and orderly sown on the bed soil of the seedling box 5 adjacent to the elastic layer 7&. The same applies to 2-row sowing.

〔effect〕

According to the configuration of the present invention as described above, the following effects can be obtained.

(a) It goes without saying that the paddy is supplied to the seeding roll in an orderly manner due to the vibration effect of the paddy guiding plate; (b) In particular, in the present invention, at least the surface layer of the N type roll is formed of a flexible and elastic material. Due to the elasticity of this elastic layer, the paddy supplied by the paddy guide plate in an orderly manner can be transported while being held between the roll guides, regardless of whether the paddy is sown in two rows separately, and the paddy being transported can be carried away. The elastic layer's restoring action allows for accurate release, even seeding, and seedling raising without large plants.

(e) Unlike the prior art, when switching between loose sowing and row sowing, it is sufficient to simply replace the paddy guide plate without replacing the sowing roll and related mechanisms, so the replacement work is easily performed.
