(2) is a receiver removing device, which is located behind the reversing device H and stops above the belt conveyor 6;
The arm 70 is configured by installing an electromagnet 71 on an arm 70 that moves downwards in response to a signal command, then moves upwards and rotates outward from the left and right sides, and the upper surface of the seedling grower 10 in the seedling box 18 that has been transferred. The magnetic material 9a, which is fixed in advance to the receiver 9 located at the holder 9, is attracted, the receiver 9 is lifted, and the receiver 9 is transferred outward and released.

To explain the structure of this specific embodiment, a cylindrical support 72 is erected on one side of the frame 1, a rotatable shaft 72a is provided inside the cylinder of the support 72, and a rotatable shaft 72a is provided at the upper end of the support 72. The arm 70 is attached via the support shaft 78 in the direction, and this arm 70
A magnet 71 is attached to the tip of the shaft 72a, and a crank device 74, which is transmitted through the one-rotation stop mechanism 73, is connected to an arm 76 fixed to the lower end of the shaft 72a via a rod 75. When the crank device 74 rotates once, the tip of the arm 70 is swung outward to one side from the state where it is located on the top surface of the belt conveyor 6 and returns to the original state where it is located on the top surface of the belt conveyor 6. In addition, a support roller 79 supporting the arm 70 from below connects the rod 8 to the actuating member of the electromagnetic solenoid 80.
1. The solenoid 80 is provided via a link mechanism 82, and is energized by a switch 84 that is linked to a detector 83 that detects when the seedling grower 9 is transferred to the lower end of the arm. When excited, the support roller 79 rotates downward, the arm 70 rotates downward, and its tip approaches or contacts the center surface of the receiver 10. Then, the link mechanism 82 and the cam 75 attached to the shaft that is transmitted and rotated by the one-rotation stop mechanism 73 are interlocked via the rod 76, the operating lever 77, and the cam flow arm 8, and the support roller 79 is moved from the lower position. It is configured to be moved upward and restored to its original stable state.

The interlocking mechanism between the detector 83 and the switch 84 is composed of a rod 90, a rotating rod 91, a rod 921, and a rotating fitting 93. The rotating fitting 93 also controls the operation of the one-rotation stop mechanism 73. By rotating the pawl 94, the clutch is turned on and the crank assembly v174 and cam 75 are rotated. In this case, the return of the support roller 79 by the cam 75 is caused by the crank device 74
It is desirable to provide a timing delay mechanism between the interlocking mechanism of the crank device 74 and the arm 76 so that the crank device 74 operates instantaneously faster than the start of the operation of the arm 70 .

When the magnet 71 is a permanent magnet, the arm 7
In conjunction with the rotation of the magnet 0, the magnet can be switched to a state in which attraction is possible or a state in which attraction is not possible. That is, the magnet 71 is fitted into the arm 70 so as to be rotatable, and is attached via a pin to a spiral groove drilled in the fitting part, so that it moves up and down when rotated. When the tip of the arm 70 is connected to the frame 95 fixed to the frame 1 via the link mechanism 96 and is positioned on the belt conveyor 6, the magnet is in a state where it can be pulled downward, and it cannot be removed from this state. This state is maintained while the arm 70 rotates in the direction, and when it reaches the outer end, the pin 99 attached to the base link 98 comes into contact with the long hole end surface of the link rod 97 having the long hole 97a, and the rod 100 The magnet 71 is rotated through the tip link 101 so that it can be moved upwardly and cannot be pulled.

Although this embodiment uses a permanent magnet 71, if an electromagnet is used, the switch can be turned on in accordance with the rotation of the arm 70.
By turning it off, the above effect can be achieved with a simple configuration.

In addition, in order to lift, move, and remove the receiver 9 of this receiver removal device, the magnet 71 is not used, but a lifting tweezers are provided at the tip of the arm 70 to grasp the protrusion formed on the upper surface of the receiver 9. Alternatively, a suction device connected to the suction device via a switching valve may be attached to the tip of the arm 70, the back surface of the holder 9 may be made flat, and the valve may be switched according to the rotation of the art 170. In the same way, adsorb the receiver 9.
It may be configured such that it can be removed.

J is a top feeding device, which is placed on the conveyor belt 7 of the fourth conveyor V and A4, and which device feeds soil about 8 minutes between each pot of the inverted seedling raising device 9. It is composed of a soil storage tank 102 and a soil feeding device 103.

Reference numeral K denotes a watering device, which is located at the rear of the above-mentioned watering device J and is a device for watering the surface of the seedling growing device 10.

A fountain nozzle 104 is attached to the water pipe.

To explain the operation of the upper side, first, the receiver 10 is placed on the lower surface of the seedling raiser 9 and the assembled seedling raiser P is transferred onto the conveyor belt 3 of the first conveyor A8 by the seedling raiser feeding device B. When the soil is placed and supplied, the soil is transferred and a small amount of covering soil is put into each pot 9a of the seedling raising device 9 being transferred by the soil covering supply device C, and then seeds (seeds) are similarly covered with soil in each pot 9a by the sowing device. Then, the bed is supplied to each pot with the bed supply bag 22E, and the full bed is leveled by the suppression device F, and pushed into the pot 9a, and the seedling raising device is laid down device G. It is sent below.

At this time, the detector 27 detects the state in which the receiver 10 has passed because the receiver-assembled seedling-raiser P is not present at the lower transfer end side of the lower part of the seedling-raiser lowering device G. A signal is generated to excite the electromagnetic solenoid 2o, and the lowermost seedling box 1 stacked face down with the rolling roller 19, 19 serving as the front support and the pin 21a serving as the rear support.
At the same time as the pin 21a is retracted to supply the pin 2
1b is protruded to temporarily support the second seedling box 18 from the bottom so that it does not fall together, and then the pin 21 is returned to its original state.
It operates so that a protrudes. In addition, the next detection by the detector 27 will be such that a signal will be emitted when the seedling raising device P with the receiver assembly passes through this detection section.

Therefore, only the side of the seedling box 18 in the transfer direction falls onto the conveyor, and the rear part is supported by the rollers 19, 19.

Then, when the seedling raising device P with the receiver assembly is sent, the front end of the seedling raising device 9 fits into the lower end of the seedling box 18 in an inclined position and is transferred, and then the pressure roller 22 He is being sent away while being held down.

When the rear support of the seedling box 18 comes off from the rear rolling roller 19, it is held down by the pressure roller 22.
- At the same time, the seedling box 18 securely fits into the seedling raising device 9.

The receiver-assembled seedling raising machine P, which is covered with the seedling box 18 and sent out from the seedling raising machine laying down device G in this way, is equipped with an inverting device ff1.
Upper and lower rollers 33a, 3 between the left and right plates 28a, 28b of H
4a and between 33b and 34b. At this time,
The rollers 33a and 33b are transmitted to each other via a counter sprocket 46, and are connected to a cylindrical shaft loosely fitted to the support shaft 3.2 via a clutch 57 and a chain 55 or 56 from the drive shaft to which the transfer roller is attached. When the fixed sprocket 46 is rotated, the seedling raising device P with the receiver assembly is also transferred rearward between the left and right plates 28a and 28b due to the rotation of the rollers 33a and 33b. When the seedling box 18 is reliably fed in, the tip of the seedling box 18 hits the seedling box detector 64 and is detected, and the fixed position stop clutch mechanism 43 is activated via the rod 65. Therefore, the support shaft 31 is
Rotation of the axis by 80 degrees The receiver-assembled seedling raising device P covered with the seedling box 18 is turned upside down. When one of the support shafts 32 rotates 90 degrees, the alternative type clutch 57 is switched by the cam body 59, so that the transmission is performed on either side between the normally wound chain 55 and the partially wound chain 56. Switched, counter sprocket 46
The direction of rotation changes in the middle of the vertical turn. Therefore, even if the seedling raising device P with a receiver assembly is turned upside down, it is transported in a fixed direction.

Next, when the seedling grower 9 is placed in the seedling box 18 and sent by the conveyor with the receiver 10 facing upward, a receiver removing device operator removes the upper receiver 10 in the following manner.

That is, when the seedling grower 9 is detected by the detector 83, the solenoid 80 is energized, and the support roller 79 of the arm 70 is activated.
moves downward, and the magnet 71 approaches and attracts the magnetic body 10a of the receiver 10. At the same time, one rotation is stopped f
ii73 operates, and the support roller 79 is forcibly moved upward from the rotated cam 75 via the cam floor wharf 8, lever 77, rod 76, and link mechanism 82, and the arm 70 is swung up. Also, at approximately the same time, the crank device 74 rotates, and the rod 75, arm 76,
The arm 7o is reciprocated through the shaft 72a. Therefore, the receiver 1o is pulled up by the magnet 71 and moved outward from the belt conveyor, and when it reaches the outer end of the movement, the pin 99 hits the long hole 97a of the link rod 97, and the receiver 1o is moved through the rod 100 to the tip link 101. The magnet 71 rotates and is pulled up, making it impossible to attract the receiver 10 .
emit. Then, only the arm 70 returns to its original state.

Subsequently, when the seedling raising container 9 from which the receiver 10 has been removed is transferred to the soil filling device RJ, there is a distance of approximately 8 cm between each pot 9a.
Soil is poured in for about a day, and then watered thoroughly using an irrigation system.

In this way, a series of seeding operations is completed.
