Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves forming a recess for seeding on the top surface of the bed soil in a seedling raising box, and moving the seedling raising box laterally with respect to a seeding machine so that the seedling raising box is moved from the seeding machine into the recessed part. This invention relates to a seeding method for seedling boxes in which seeds are supplied by falling.

Conventionally, when forming a recess for sowing in the above-mentioned sowing method, as shown in FIG. The seedling box 2 was formed in a V-shape with an upward opening so that the seedling box 2 had an almost identical tilted position, but the seeds dropped from the seeding machine were moved from the recess 8 into the seedling box 2 due to the movement of the seedling box 2. It is easy to jump out in the opposite direction to the direction of movement, so
There were problems such as the rows of germinated seedlings being disordered, resulting in missing plants when planted in the field.

In view of the above-mentioned conventional situation, an object of the present invention is to ensure that seeds enter the recesses when sowing into seedling boxes, prevent them from flying out from the recesses, and ensure that seeds can be sown in rows. It is in the point of doing.

In the method of the present invention, in the seeding method for a seedling raising box, the seeding recess is formed into a long groove shape that intersects the conveying direction of the seedling raising box, and one side of the seedling raising box in the conveying direction is a gently sloped surface and the other side is a gently sloped surface. The side surface is formed into an upward opening shape with a steep slope, and the seeds are sown in the seeding recess while being transported with the gently sloped surface positioned on the lower side in the transport direction of the seedling box.

In other words, the surface of the bed soil of the seedling raising box on the lower side in the transport direction with respect to the transporting direction of the seedling raising box is a gently sloped surface.
By forming a sowing recess with a steeply sloped surface on the upper side in the conveyance direction, the seeds dropped from the seeding machine can be reliably dropped into the recess by the guiding action of the gently sloped surface. , it is possible to reliably prevent seeds from flying out of the recesses in the opposite direction to the direction of movement of the seedling box due to the movement of the seedling raising box by the catching action of the steeply sloped surface on the seeds. It has become possible to reliably embed the seedlings in the field without leaking, and to perform extremely good row sowing, which in turn has made it possible to smoothly and successfully plant seedlings in the field.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, a seedling growing box 2 loaded with a porous seedling growing sheet 1 made of paper, sponge, etc. and having a rectangular shape in plan view is conveyed on a pair of conveyor belts 3 in its longitudinal direction. The seedling raising box 2 is placed so as to face the direction perpendicular to the direction, and the position of the seedling raising box 2 relative to the belt is adjusted by an idling roller 4 attached to a fixed support shaft 5.
Idle roller 4 is attached to a support frame 7 which is elastically biased by a spring 6 on both sides of the seedling raising box 2.
A large number of seedling growing boxes 2 are continuously transported in a state determined by b. Then, the seedling raising box 2 being transported is
A hopper 15 that supplies bed soil A, a groove-forming roller 9 that presses and forms seeding grooves 8 that span almost the entire length of the seedling-raising box 2 on the bed soil A in the seedling-raising box 2 at equal pitches in the conveyance direction; A seed feeding hopper 11 equipped with a seed feeding roller 10 that feeds a fixed amount of rice seedlings into the groove 8, a hopper 12 for covering soil, and
Pass through the irrigation nozzle 13 in that order,
Row sowing into a seedling raising box 2 is automatically and continuously performed.

Then, the seedling raising box 2 subjected to the above-mentioned sowing treatment is
In the seedling nursery room, the seeds are germinated and rooted while being kept at the appropriate humidity and temperature, and the pine seedlings are grown to be loaded into the seedling stand of the rice transplanter.

When the seeding grooves 8 are formed by the groove forming roller 9, depending on the shape of the groove forming protruding portions 9a,
As shown in FIG. 4, in a longitudinal cross-sectional view of each groove 8, the side that precedes the movement of the seedling raising box 2, that is, the surface on the downstream side of transport with respect to the transporting direction of the seedling raising box is a gently sloped surface 8a. A substantially V-shaped groove 8 is formed so that the other surface becomes a steeply inclined surface 8b having a substantially vertical posture.

In other words, by making the surface that precedes the movement of the seedling box 2 into the gently sloped surface 8a, the seeds falling and supplied from the seed supply hopper 11 are transferred to the gently sloped surface 8a.
In addition to ensuring that the seeds fall into the groove 8 with the guiding action of a, the seedlings are prevented from flying out from the groove 8 due to the movement of the seedling box 2 in the opposite direction to the direction of movement of the seedling box 2, and by the hopper 12 for covering soil. The seed-catching action of the steeply sloped surface 8b reliably prevents the seeds from flying out of the groove 8 when covering with soil or spraying water with the irrigation nozzle 13, and the seeds are reliably sown in rows as desired.

Note that the specific inclination angle, groove pitch, groove depth, etc. of the groove slope surfaces 8a, 8b can be changed as appropriate, and these grooves are collectively referred to as the seeding recess 8. Moreover, instead of sowing in rows in the longitudinal direction of the seedling raising box 2, it may be sown in rows in the width direction of the seedling raising box 2.

Furthermore, in order to form the sowing recesses 8 in the bed soil A, instead of using the soil pressing roller 9, a fifth
As shown in the figure, various types of devices or tools can be used to form the seeding recess 8, such as pressing the plate-shaped member 14 against the soil A of each seedling box 2 from above. It is possible.

Further, various types of devices can be used for dropping and supplying seeds to the seeding recesses 8 formed in the soil bed A, and these devices are collectively referred to as a seeding machine 11.

The present invention is directed to various types of seeding methods, such as those in which seedling boxes are conveyed manually or continuously and automatically conveyed by a belt conveyor or the like.

Note that although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
