Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a seedling raising facility for raising all seedlings such as rice seedlings that are planted using a rice transplanter.

Conventional technology All seedling planting is done mechanically, such as rice transplanters. This is now being done artificially, so to speak.

For this purpose, for example, as disclosed in Japanese Utility Model Application Publication No. 48-610.07, seedling growing boxes are provided across all multiple rows of trolleys consisting of a plurality of trolleys placed in multiple tiers. A seedling raising facility has been proposed in which the seedling growing boxes on each trolley are irrigated with water using an irrigation means that is moved by the user.

Problems to be Solved by the Invention However, as disclosed in the above-mentioned publication, for example, the movable watering means provided in the conventional seedling-raising facility is located at a distance n' from the side of the row of trolleys. It is assumed that water is sprayed from the ft position towards the row of bogies to irrigate the row of trolleys. However, it is undesirable to water the seedling boxes only in small areas, and uniformly water the entire surface of multiple seedling boxes.

In other words, when watering or spraying chemicals on trees or other seedlings planted in a greenhouse, etc., the water or chemicals should be spread almost evenly to all the seedlings by rough watering or spraying. However, if a large number of small seedling boxes are placed close together, even if there is a vertical distance of 'r6' between them, they can be placed on a trolley and watered from a considerable distance. Irrigation is extremely uneven and uneven.

Therefore, the growth of seedlings is highly uneven both when looking at a large number of seedling boxes as a whole and when looking at individual seedling boxes. Therefore, the seedling raising facilities for rice seedlings etc. that have been proposed in the past are not practical and remain merely proposals. The reality is that there are.

Therefore, the present invention aims to provide a new seedling-raising facility that is equipped with an irrigation means for uniformly watering a large number of seedling-raising boxes, and is capable of uniformly raising seedlings on a large scale while saving labor. It is something to do.

Technical Means Taken to Solve the Problems The seedling raising facility of the present invention developed under the object of the present invention can place seedling raising boxes B spaced apart from each other vertically, as illustrated in the attached diagram. Multiple trolleys Wft with multi-level shelves 3 Straight rails 6

(i=, each nozzle N is arranged and attached to the row of trolleys so that it is located close to it from the side of the six rows of trolleys, and each nozzle N is installed in the seedling box B of each stage in the vertical direction of the trolley W. Seedling box B
The number of injection ports 22b'e corresponding to the number of stages of the shelves 3 are provided to individually irrigate water from the sides.

In order to fully water the seedlings grown in the many seedling boxes B placed on the shelf 3 of the working trolley W, the beam 21 (BE) is used. By moving each bogie row LK to the side of each bogie row, each nozzle is attached to the water supply pipe 23). Water is supplied into the nozzle N and water is jetted all at once from the plurality of jetting ports 22b of each nozzle N.

At this time, as shown in Fig. 10, the seedling boxes B on each stage on the platform W are individually sprayed with water from a position close to the side of the platform W, so that the entire surface is uniformly irrigated. , Such watering is performed simultaneously for each of the upper and lower rows of seedling box B. Separate injection ports 22 in each tier of seedling box B
Considering that water is supplied separately from b, the upper and lower parts are watered individually.
(Uniform watering is achieved throughout the entire seedling raising box B on the 1'71 stage.

By reciprocating the beam 21 (BE)', the nozzle N is reciprocated between one end and the other end of the row of trolleys and watering is repeated, thereby raising a large number of seedlings on multiple trolleys of each row of rows of trolleys. The same watering can be repeated for all boxes B, and at this time, the nozzle N attached to the water supply pipe 23, which is fixedly supported on the beam 21 (13E), is always moved in parallel with the row of trolleys. Injection port 22 for each stage of seedling box B
It is assumed that the relative position Wt of b is maintained constant throughout, and each injection of water is performed from a constant position.

EXAMPLE To explain the seedling raising facility according to the present invention with regard to the example,

．． (Figure 10) vf - The interval is set so that it can be placed at a distance. The end partition 2 of each truck W is provided with a vertical bar 4t at the center in the width direction, and each truck is provided with an appropriate number of wheels 5. The wheels 5 are moved into the rail grooves 6 on the floor surface.As shown in FIG. It is a shallow box with all 7 holes drilled.

Then, as mentioned above, a cart W is loaded with a large number of seedling boxes B.
As shown in Fig. 1.2.5, a plurality of carts Wt-
t-A convoy of intersecting vehicles arranged in series on top of each other, arranged in multiple rows with a fixed interval between each row, and installed in large numbers at fixed positions within the facility. Tonasa t is there.

The distance between the two car trains at the center of the width of the facility should be slightly larger as shown in Figure 1.2.5.
Within this interval, the following tank cars TTh are provided. In other words, as shown in FIG. 6, this tank truck T is equipped with an appropriate number (4) of wheels 9 that move within the rail grooves 8 on the floor that lie on the truck train. The wheel 9 at one end is forcibly rotated by a reversible motor 10 to reciprocate in the rail groove 8, and is self-propelled. This tank car T also has a large capacity water tank 11 mounted thereon, and as shown in FIG. A pump 13 that sucks and discharges water is installed on the tank truck T, and the water supply pipe 1 on the tank truck T is operated by the pump 13.
The discharge pressure is as follows:
The water supply pipe 14 is led into the water tank 11 from the middle and is connected to a reflux pipe 15.
It is possible to adjust the pressure by inserting the pressure adjustment %-11'P16.

Rail 1 located at the center of the width at the ceiling level in the facility
7 and rails 18 located at both ends are installed along the length direction of the facility, and the beam 21 provided on the entire lower surface side of the rollers 19 and 20 that transfers on these rails 17 and 18,
It is installed as shown in Figure 2.6-8 etc. The beam 21 is fixed to the top end of the tank car T, and the ceiling level can be moved back and forth as the tank car T moves back and forth. One vertical nozzle (N) facing the side of the bogie row) is inserted into the nozzle N, which has an inverted gate shape between each row and is straight at the side end, and taken out into the main body of the pipe body as shown in Figure 9. A large number of nozzles 22 as shown are installed at regular intervals along the vertical direction, and nozzles N are provided between the seedling boxes 3 on the trolley W from the side as shown in FIG. This nozzle N is connected to the beam 21 at its upper end.
The tank car T is connected to a water supply pipe 23 which is fixedly supported and connected to the water supply pipe 14 on the tank car T. 24 shown in Figure 5.6 is a turnbuckle 24
The suspension support for the nozzle N is equipped with ai 0, and the above-mentioned 7
As shown in Fig. 9, the valley jetting tool 22 has an oval jet opening 22b'i in the center of the slint 22a with a shape at its tip, which is expanded into a fan shape to form a seedling nursery box. It is said to spray water over the width of B.

Also, both motors 10.1 on the tank army T that is running and moving
It is assumed that power is supplied to the device 2 via a flexible cable 25 as described below. That is, another rail 26 made of H-beam steel is installed above the rail 17 in the center of the width of the facility and along the rail 17, and as shown in FIG. The hanging fitting 27 is slidably supported, and the flexible cable 25 connected to the power supply at the base end and connected to the motor 10.12 on the metal tank car T is hung, and the entire end is moved together with the tank car T. ' so that power is supplied to the motor 10.12 via the cable 25.
-ing In addition, the direction of rotation of the motor 10 is completely changed at each end of the movement when the tank is disembarked and the tank RL Hayabusa is moved to automatically change the running direction of the tank RL Hayabusa. This can be done by placing the actuator at the end of the movement and switching the actuator into contact with an actuator that is fixedly installed on the floor.

An example of a method for raising seedlings that is carried out using the seedling raising facility illustrated in FIGS. 1-10 will be described. Inside the seedling raising box B, the seedling raising box B
Before loading the seeds onto the cart W, the seeds are sown. For this purpose, the seedlings are placed in a seedling raising box B with a bed made of, for example, soil or polyurethane foam, and seeds such as rice seed are sown thereon using, for example, a known sowing machine, and covered with soil as appropriate. Then, the seedling raising box Bt-1 after sowing is either transported by another trolley and loaded using the shelf board 3t on a number of trolleys W arranged in the seedling raising facility as described above, or The state shown in the figure is obtained by loading the shelves 3 onto the cart W at another location and then moving the cart Wt to arrange it as described above. This is where the seedling-raising period begins, and if necessary, the temperature is adjusted by blowing warm air into the facility or installing mercury lamps. In the case of raising rice seedlings, etc., watering is not performed until germination, but watering is performed from the time when germination is almost complete, about three days after sowing. This irrigation is carried out in the following preferred manner.

In other words, this watering is applied by starting the motor 10 on the tank car T, for example, 80 tons along the convoy of tank cars T.
While reciprocating over a long distance of, for example, 15 m/s, at a low speed of, for example, 15 m/s, the motor 12 drives the pump 13 to pump a water column of, for example, about 20 m from the water tank 11 at a certain discharge pressure, and the water supply pipe 14. Water is supplied at this water pressure to each nozzle N through 23'e, and the jetting flow rate from each spout tool 22 is, for example, 1401/min. The interval α of box B
Water is injected from the nozzle N's spout 22 as shown in FIG. n
It is. By proceeding with watering in this way, water is applied to each seedling box B at equal time intervals. Since watering is performed by moving the tank truck T and nozzle N, it is not necessary to move a large number of heavy carts W during watering, and the watering work is performed completely naturally, resulting in significant labor savings. Also, appropriately selected
Since each seedling growing box B is watered with a constant pressure and a constant supply amount that are appropriately selected from the tank iT that runs at a constant speed on L7, uniform watering is performed under optimal conditions for all seedling growing boxes B. , uniform and good seedling growth can be obtained in all seedling boxes B.In addition, in the conventional case, in order to prevent seed germination from heaving up, especially in the soil-covered area, the seedling cart was not used during the germination period. The seedling tubes are stacked closely on top of each other, and the weight of the upper seedling box is used to increase the medium and
However, if the facility shown in the figure is installed, watering from the nozzle N that uniformly and uniformly waters the seedling box above and below the position 11 during the germination period will reduce the hourly irrigation rate. By selecting an appropriate amount of water, the floating soil can be caused to sink downward by the flowing action of water, so that it does not interfere with the planking of seedlings. If a large amount of water is desired as the seedlings grow, this adjustment can be made by increasing the set pressure of the pressure regulating valve 16. Water tank 1
1, a water amount detection device interlocked with a detection means such as a float, a stop actuation device that automatically stops the tank car T in conjunction with the detection operation of the water amount reduction below a certain amount by this device, and a tank car T using this device. By providing an automatic water supply device that automatically supplies water from the water supply port of the water tank 11 after the water tank 11 has stopped, this invention automatically replenishes water to the tank truck T, etc., thereby automating the seedling raising work, especially the watering work. In addition, various types of automatic control and automatic driving can be easily adopted and implemented. In this way, seedlings are raised while being watered for a certain period of time after germination, for example, 6 days, and when the expected seedling growth is achieved, the trolley W is pulled out and the seedling raising box B is brought to individual farmers. I will hand it over to you, etc.

Next, another embodiment shown in FIG. 11 will be explained.
In this embodiment, the rail 17.
Three rails 40.41 similar to beam 21 are installed in the length direction of the bogie train, and these rails 40.41 support and guide the wheels 42.43, similar to the beam 21 described above. A running beam BE is provided extending in the width direction of the facility, and the running beam BE is fixedly supported by the beam BE along the running beam BE. : It is connected to the friend water supply pipe 44 and hangs down from the nozzle Ne beam BE similar to the nozzle N, but the beam B
The running drive means of E and the water supply means for supplying water to the nozzle N through the water supply pipe 44 are different from those in the previous embodiment and are constructed as follows.

That is, one end of the wire ropes 45 and 46 fixed to each other is provided at both ends of the running beam BE, and the other ends of these wire ropes 45 and 46 are connected to the rails 41 on both sides.
The winch 4 installed on the floor is guided downward by the pulleys 47 and 48 at the front and rear ends of the rail 41.
9.50, and when one of the front and rear winches 49 or 50 is operated for winding, the other front and rear winch 50 or 49 is operated for winding. It is designed to obtain reciprocating motion of the beam BE. In addition, a flexible hose 51 is connected at one end to the water supply pipe 44, and the other end of the hose 51 is guided by a pulley 52 at the end of the tear rail 40 to guide it downward. Then, wind up the hose 5 to the torque motor winch 53 installed on the floor.
1. The other end of the hose 51 is guided into the drum of the winch 53, pulled out from the center of the drum, and connected to a pressurized water supply source such as a pump or water faucet (not shown), and the hose 51 is connected in synchronization with the travel of the beam BE. , are fed out and rolled up while constantly applying tension to the nozzle N, and water is continuously supplied to the nozzle N from the pressurized water supply source via the hose 51 and the water supply pipe 44.

The seedling raising method carried out using the seedling raising facility shown in FIG. When the tank army Tffi is omitted and the facility is made up of nine components as in the case shown in the figure, the cost can be reduced by omitting this tank car T and omitting the water replenishment device for the moving tank car T. It's what you get.

Next, another embodiment of the seedling raising facility shown in FIG. 12, which has a simpler structure, will be explained. This other embodiment is the same as that shown in FIG. 11, but the winches 49 and 50 are omitted. , equivalent to the pulley 47.48 (7)7'-')-'E is a drive belt, rope, chino, etc. whose both ends are fixed to the running beam BE to the wheel body 57.58 such as a sprocket wheel. The belt 60t-suspension is rotated, and a reversible motor 61 is attached to the wheel body 57 at one end to rotate the belt 60t. That is, in the one shown in FIG. 12, the four winches 49, 50 in the one shown in FIG. 11 are replaced with two simple motors 61, and the structure is simplified accordingly.

Furthermore, to further simplify the structure, as shown in FIG. 13, a drive band 70 corresponding to the drive band 60 in the one in FIG. The wheels 71 and 72 at both ends are suspended by only one wheel, and the wheel 71 at one end is driven by a winch motor of the winch 53 for the hose 51. For example, as shown in FIG. This can be done by suspending a drive belt 75t between a wheel 73 attached to the wheel 71 and a wheel 74 attached to the winch 53 as shown in the figure.

Effects of the Invention The seedling raising facility of the present invention is used as a mobile watering means for watering a large number of small seedling growing boxes B which are placed on a trolley W in a dense manner. Since the vertical nozzle N' having a plurality of individual injection ports 22bi for seawater is used, water is sprayed separately from the side close to each of the upper and lower seedling boxes B. It is assumed that Nu water is distributed evenly and uniformly in each seedling box B by drifting water into the seedling box B from the position, and even if we look at the entire number of seedling boxes B, it is assumed that 7n is applied to each seedling box B individually. Since the seawater is individually sprayed with water jetted from the water injection port 22b, it is possible to achieve even and uniform seawater between the seedling boxes 8. To make the growth of seedlings uniform throughout a seedling-raising box and to obtain uniformly raised seedlings. A water supply pipe 23 fixedly supported on the traveling upper beam 21 (BE) (a nozzle N installed at a position close to the side of the bogie train) is
The seedlings S at each stage are moved while always maintaining a parallel relationship with the row of trolleys guided by the straight rails 6.
The relative position of the injection port 22b with respect to li B is maintained constant, and each injection of water is performed from a constant position, contributing to uniform seedling growth.

Therefore, according to the present invention, which performs Kl/)l water all at once using a plurality of nozzles N't- which produce the above-mentioned effects for each of a plurality of bogie trains, it is possible to perform Kl/)l water while saving labor. Large-scale seedling raising can be carried out so that uniform seedling raising results can be obtained throughout.
