(Prior art) Conventionally, long frames are arranged in parallel in the front-rear direction, a rotation shaft a in the left-right direction is mounted on the frames, and two guide rolls c are attached to the rotation shaft a to horizontally transfer the seedling box b. A seeding device is known in which a transfer table is fixedly fixed, an irrigation nozzle d is provided above the transfer table, and a seed supply device is provided on the downstream side of the irrigation nozzle d.

Furthermore, in the conventionally known Japanese Patent Application Laid-Open No. 54-85907, there is provided a rotary shaft mounted at a predetermined interval on frames arranged long in the front and back direction, and soil fixed to the rotary shaft. In a seeding device consisting of a transfer table having guide rolls for horizontally transversely transferring the seedling raising boxes, a seed supply device provided above the transfer table, and a grooved roller, a rotating shaft at the bottom of the grooved roller has left and right sides. A seeding device is described in which three guide rolls on both sides and in the center are fixed.

(Problem to be solved by the invention) In the device described in the above-mentioned Japanese Patent Application Laid-Open No. 54-85907, in order to absorb the strong pressing force of the grooved roller, the lower rotation shaft of the grooved roller has left and right shafts. Although three guide rolls on both sides and in the center are fixed, the seeding device has another problem in that water from the irrigation device accumulates in the center.

That is, although the known seedling raising box b is made of synthetic resin or the like, when the seedling raising box b is supported by the two left and right guide rolls cc and receives water from the irrigation nozzle d, as shown in FIG. As shown in FIG.
(Figure), there is a problem in that the supplied rice seeds float due to the accumulated water f, making it impossible to sow them uniformly.

Therefore, the present invention prevents dents in the center of the seedling raising box during watering, prevents standing water on the soil surface, and prevents the supplied rice seeds from floating.

(Means for Solving the Problems) Therefore, the present invention provides a plurality of rotary shafts 7 mounted at predetermined intervals on frames 5, 5 arranged long in parallel in the front and back direction, and soil fixed to the rotary shafts 7. A seeding device comprising a transfer table 1 having guide rolls 8 for horizontally and horizontally transferring seedling raising boxes 2 supplied with seedlings, an irrigation device 9 and a seed supply device 15 provided above the transfer table 1. A plurality of rotary shafts 7 between the seedling supplying device 15 and the seedling supplying device 15 are arranged so that the water applied to the seedling raising box 2 by the irrigation device 9 soaks into the center of the soil surface in the seedling raising box 2 without being stored. This is a seeding device in which three guide rolls 8 on both left and right sides and in the center are fixed.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a transfer table that horizontally transfers the seedling growing box 2, and is formed long in the direction in which the seedling growing box 2 is transferred. The seedling raising box 2 is made of synthetic resin or the like and has a rectangular drawer shape when viewed from above, and a bottom plate 3 thereof has a large number of drainage holes 4 formed therein.

The transfer table 1 has frames 5, 5 which are long in the front and back direction.
are arranged side by side and placed on the floor soil by support legs 6 provided at desired positions of the frames 5, 5. An irrigation device 9 is provided above the transfer table 1. 10 is an irrigation nozzle with numerous irrigation holes 11 formed on its lower surface;
2 is a connection pipe that connects the irrigation nozzle 10 to the water supply, 13 is a water pressure gauge, and 14 is a valve.

A seed supply device 15 is provided on the downstream side of the irrigation device 9.
(Irrespective of the positional relationship between the irrigation device 9 and the rice seed supply device 15, the irrigation device 9 may be provided on the lower side of the transfer side of the rice seed supply device 15.) 16 is a feed roll.

Rotating shafts 7 in the left and right directions are mounted on the frames 5, 5 at predetermined intervals, and guide rolls 8 for transporting the seedling box 2 are fixed to the rotating shafts 7.
A rotating shaft 7 between the irrigation nozzle 10 of the irrigation device 9 and the delivery roll 16 of the seed rice supply device 15
In this step, three guide rolls 8 are fixed, and the seedling raising box 2 is transferred to the seedling supplying device 15 while supporting the right and left sides and the center portion of the bottom plate 3 of the seedling raising box 2 by the three guiding rolls 8.

(effect) Next, we will discuss the effect.

Since the present invention has the above-described configuration, when the seedling raising box 2 supplied with bed soil is placed on the guide roll 8, the seedling raising box 2 is transferred by the guide roll 8 and is placed above the transfer table 1. It is irrigated by the irrigation device 9 and supplied with seed rice by the seed rice supply device 15 on the downstream side of the irrigation device 9.

In this case, the guide roll 8 for transporting the seedling box 2
Since three guide rolls 8 are fixed to the rotary shaft 7 between the irrigation nozzle 10 of the irrigation device 9 and the feeding roll 16 of the seed supply device 15, the seedling raising box 2 is constructed with its bottom plate While the right and left sides and center portions of the rice seedlings 3 are supported, water is applied through the irrigation hole 11 of the irrigation device 9 and transferred to the seed supply device 15. Therefore, even if the bed soil receives enough water from the irrigation device 9 to become moist and becomes heavy, the central part of the seedling nursery box 2 is prevented from denting, and excess water is drained from the drainage hole 4 below. Since the drainage is more efficient, water does not accumulate on the surface of the soil.

(Effects) In the device described in JP-A-54-85907, in order to absorb the strong pressing force of the grooved roller, the rotating shaft at the bottom of the grooved roller has three rollers on both left and right sides and in the center. However, the seeding device has another problem in that water from the irrigation device accumulates in the center.

That is, although the known seedling raising box b is made of synthetic resin or the like, when the seedling raising box b is supported by the two left and right guide rolls cc and receives water from the irrigation nozzle d, as shown in FIG. As shown in FIG.
(Figure), there is a problem in that the supplied rice seeds float due to the accumulated water f, making it impossible to sow them uniformly.

However, in the present invention, a plurality of rotating shafts 7 mounted at predetermined intervals on frames 5, 5 arranged long in parallel in the front and back direction, and a seedling raising box 2 supplied with soil fixed to the rotating shafts 7, are arranged horizontally. Guide roll 8 to be transferred
In a seeding device consisting of a transfer table 1 having a transfer table 1, an irrigation device 9 and a rice seed supply device 15 provided above the transfer table 1, a plurality of rotations between the irrigation device 9 and the seed rice supply device 15 are provided. The shaft 7 is provided with three guide rolls 8 on both left and right sides and in the center so that the water applied to the seedling raising box 2 by the watering device 9 permeates into the center of the soil surface inside the seedling raising box 2 without being stored. (a) Since the plurality of rotary shafts 7 between the irrigation device 9 and the seed supply device 15 are provided with guide rolls 8 on the left and right sides and in the center, Even if the entire soil is irrigated and becomes heavy, it will prevent the center from denting.

(b) Since the center of the seedling nursery box 2 does not dent, after watering in an amount that evenly moistens the entire bed soil, excess water is drained from all drainage holes 4, preventing water from accumulating on the surface of the bed soil. do.

C. Since standing water is prevented from standing in the center of the bed soil in the seedling raising box 2, it is also possible to prevent seed rice from floating, allowing for uniform sowing.

D. Since it has an extremely simple configuration, it is easy to implement and can be manufactured at low cost.

This effect is achieved.
