In the automatic seeding device, a sensor is attached to the terminal end of the transfer table, a pump and a motor are provided on the transfer table, the irrigation device is connected via the pump, and the seed feeding device, the soil covering feeding device, and the transfer device are connected to each other via the pump. The platform is connected to a motor, and when the seedling box collides with the sensor, the irrigation device, the seed supply device, the soil covering supply device, and the transfer platform are configured to stop.

(Problems to be Solved by the Invention) In the above-mentioned known device, the sensor is attached to the terminal end of the transfer table, but the sensor is simply attached to the terminal end, and the mounting position in the left and right direction is not contrived at all. There is a problem because it has not been done. That is, if it is mounted in the center, it will hit the sensor when picking up the seedling box, damaging the sensor, making it difficult to pick it up. The work becomes much easier if the sensor is mounted on the side where the worker is not present. In addition, in the known method, the sensor is directly attached to the terminal end of the transfer table, but if the sensor is attached directly to the transfer table,
The transfer table itself becomes long, and there are also difficulties in transferring packages.

In the present invention, the sensor can be easily attached and detached together with the mounting frame to facilitate packaging, and the sensor is attached at a position where it does not interfere with taking out the seedling box.

(Means for Solving the Problem) Therefore, the present invention provides a seedling-raising box transfer table 1 capable of horizontally transporting seedling-raising boxes 2, an irrigation device 8 and a seed supply device 29 installed above the transfer table 1. and a soil covering supply device 30, etc., a sensor 36 provided on the terminal end side 7 of the transfer table 1, and a solenoid valve 27 and motor 5 provided at an arbitrary position on the transfer table 1, in which the irrigation device 8 are connected via the electromagnetic valve 27, and are connected to the seed supply device 29, the soil covering supply device 30, and the transfer table 1.

Inside the negative pressure chamber 14 is a fitted body 1.
5 are fitted together, and an injection port 16 having a smaller diameter than the water passage port 12 is formed at the center of the fitted body 15. The injection port 16 injects water into the negative pressure chamber 14 . A hose connection pipe 17 is attached to the outer peripheral wall of the negative pressure chamber 14. The upper end of the suction hose 18 is engaged with the hose connection pipe 17, and the lower end of the suction hose 18 is opened into the solution 20 in the chemical solution tank 19.

An intermediate pipe 21 is attached to the inlet side 13 of the suction section 10. 22 is a water pressure chamber, and 23 is a water pressure gauge. A valve 24 is attached to the inlet side of the intermediate pipe 21, and a water supply hose 25 is connected to the valve 24. The water supply hose 25 is connected to a solenoid valve 27 provided in a control box 26, and connected to the water supply via a communication hose 28.

29 is a seed feeding device, and 30 is a covering soil feeding device. These are driven by the motor 5.

As shown in FIG. 1, a guard body 31 is formed on the transfer table 1 other than the terminal end 7 to prevent the seedling raising box 2 from shifting to the left or right.
Guard body 3 is at least as long as 2 seedling boxes.
It is formed in a state without 1. The portion shown as width T in FIG. 1 shows a state where the guard body 31 is not present. Without the guard body 31, the seedling growing box 2 can be moved sideways and taken out without having to lift it, making the taking out operation extremely easy.

The rubber rolls 4, 4 on the terminal end side 7 of the transfer table 1 protrude above the left and right frames. A mounting frame 32 is further attached to the terminal end side 7.

A contact fitting 33 is attached to the base of the mounting frame 32, and the corresponding fitting 33 is brought into contact with the terminal end surface of the transfer table 1 and is detachably fixed with a bolt.

34 is a mounting bracket, and 35 is a nut.

A sensor 36 is attached to the mounting frame 32 and connected to the control box 26 by a connection cord 37. The sensor 36 is provided biased to either the right side or the left side with respect to the transfer direction of the transfer table 1.

As described above, the control box 26 has the solenoid valve 27 and insertion sockets 38, 39, and 40, and the cord of the motor 5 is inserted into the insertion socket 39 to rotate. Reference numeral 41 indicates a mounting bracket for attaching the control box 26 to the transfer table 1, and 42 indicates a power cord.

(Function) A Overall function When the seedling raising boxes 2 filled with bed soil are supplied one after another without any gaps to the starting end side 6 of the transfer table 1, the seedling boxes 2 are irrigated as they pass under the watering pipe 9, and the seed supply device 29 When passing under the soil covering supply device 30, seeds are sown, and when passing under the soil covering supply device 30, it is covered with soil.

When passing under the sprinkler pipe 9, the water is irrigated, but the water flowing from the water supply through the connection hose 28, the solenoid valve 27, the water supply hose 25, and the valve 24 passes through the water pressure chamber 22, and further flows through the negative pressure chamber 1.
4, the solution 20 is then irrigated by the suction hose 18 on the principle of atomization.
Inhale and spray solution 20 at the same time as irrigation.

The amount of water discharged from the sprinkler pipe 9 is proportional to the pressure, but in the present invention, since a water pressure gauge 23 is attached, the amount of water can be determined from the scale.

As a result, the seedling boxes 2 are taken out one after another at the end side 7, but the removal work may not be done in time.
is activated to turn off the motor 5 for moving the seedling raising box 2, and at the same time, the solenoid valve 27 is also turned off. Therefore, the irrigation device 8, the seed supply device 29, the soil covering supply device 30, and the transfer table 1 are stopped.

B. Partial action As mentioned above, the seedling raising box 2 is transferred from the starting end 6 to the terminal end 7 without any gaps, and is taken out laterally at the terminal end 7.
A part of the guard body 31 corresponds to the length of the seedling raising box 2.
Since it is not provided, it can be taken out simply and easily.

Therefore, since the sensor 36 is biased to either the right or left side with respect to the transfer direction of the transfer table 1, if you work while standing on the side where the sensor 36 is not located, you will not be disturbed by the sensor. The seedling raising box 2 can be taken out, making the work easier and preventing accidental contact with the sensor. Therefore,
There is no risk of stopping the entire device, and work can be done efficiently.

Furthermore, if the seedling growing box 2 is picked up while in contact with the sensor 36, there is a risk of damaging the sensor 36, but since the seedling growing box 2 can be taken out without being interfered with by the sensor 36, there is no such risk.

Since the sensor 36 is attached to the mounting frame 32, and the mounting frame 32 is detachably provided on the transfer table 1, the transfer table 1 itself can be shortened, making it easy to pack and transfer. Further, the sensor 36 can be easily installed to order by fixing the mounting frame 32 to the transfer table 1 with screws or the like and connecting the connection cord 37 to the insertion socket 38. Also, depending on the installation location of the transfer table 1,
The sensor 36 can be attached to the side of the seedling raising box 2 that is convenient for the work of taking out the seedlings.

(Effects) The present invention includes a seedling box transfer table 1 capable of horizontally transporting a seedling box 2, an irrigation device 8, a seed supply device 29, a soil covering supply device 30, etc., which are installed above the transfer table 1. In the device having a sensor 36 provided on the terminal end side 7 of the transfer table 1, and a solenoid valve 27 and a motor 5 provided at an arbitrary position on the transfer table 1, the irrigation device 8 is equipped with the solenoid valve 27.
The seed supply device 29, the soil covering supply device 30, and the transfer table 1 are connected to be driven by a motor 5.
and the solenoid valve 27 and the sensor 36 in the seedling box 2.
When the water collides with the sensor 36, the motor 5 is stopped, the solenoid valve 27 is closed, and the irrigation device 8, the seed supply device 29, the soil covering supply device 30, and the transfer table 1 are stopped. A mounting arm 32 that protrudes in the direction of extending the transfer table 1 is detachably attached to the terminal end of the table 1, and the sensor 36 is located at the terminal end of the mounting arm 32 and on the left and right sides of the seedling box 2 being transferred. Because the automatic seedling box seeding device is installed biased to either side, (a) the sensor 36 is installed biased to either the right or left side with respect to the transfer direction of the transfer table 1; If you work while standing on the side where 36 is not located, you will not be disturbed by the sensor and the seedling box 2
The sensor can be removed easily, making work easier and preventing accidental contact with the sensor. Therefore, there is no risk of stopping the entire device, and work can be done efficiently.

(b) Since the sensor 36 is detachably attached to the transfer table 1 using the mounting frame 32, the sensor 36 can be attached to the side convenient for taking out the seedling box 2 depending on the installation location of the transfer table 1.

C. In the known method, the sensor is directly attached to the transfer table, so the transfer table itself becomes long, and there are also difficulties in packaging and transferring.However, in the present invention, the sensor 36
Since it is removably attached to the transfer table 1 using the mounting frame 32, the length of the transfer table itself can be shortened, and packaging and transfer is extremely easy.

This effect is achieved.
