 Next, the operation of the above configuration will be described.

In this example, the pot (sample) 201 in which the plant was planted was sprayed with the test chemical solution in the first spray chamber A1, and at the same time, the soil for cultivation was filled in the second spray chamber A2. The pot (sample) 202 is sprayed with the test drug solution.

First, the belt conveyors 3 of the first and second loading devices B1 and B2
Drive 3,54. Then, a plurality of samples 201 and 202, which are respectively placed on the tray 200 in an aligned manner, are sequentially supplied onto the respective belt conveyors 33 and 54. When the tray 200 reaches the end of the belt conveyor 33, a stopper that normally occupies the protruding position The movement of the stop pin 36 of 34 is stopped, the drive motor 32 of the belt conveyor 33 is stopped, and the shutter 49 of the first spray chamber A1 which is normally closed is released by the rodless cylinder 48. To be done.

At the same time, the rodless cylinder 41, which is normally moving backward (moving to the right in the figure) of the transfer mechanism 40, is moving forward, and the pressing plate 47 which is normally recessed below the belt conveyor 33, It is moved up by the cylinder 46, and the cylinder 35 retracts the stop pin 36.

Therefore, the tray 200 with the pressing plate 47 abutted at its end is
Are pushed onto the rotary stage 1 from the end of the belt conveyor 33 by the rodless cylinder 41. When this replacement is completed, the rodless cylinder 41 retracts and the pressing plate 47
Is lowered, the shutter 49 is closed, and the stop pin 36 is projected again. Then, the belt conveyor 33 is driven again, and the next tray 200 is transferred to its end position. Second
The carry-in device B2 is also operated in the same manner as above.

On the other hand, the chemical solution supply section D is also operated, and the rodless cylinder 74 causes the container stand 73 in the front row on the supply station 71.
On the guide rail 70, and then the rodless cylinder 76 moves the container stand 73 to bring the chemical liquid container 7 at the forefront thereof to a position facing the chemical liquid container elevating mechanism F.

Then, as shown in FIG. 13, the rodless cylinder 121, which normally occupies the lowered position of the liquid medicine container elevating mechanism F, causes the chuck 123 attached to the mover 121a to hold the liquid medicine container 7 at the forefront. It also moves up. Therefore, the drug solution suction portion 96 located above is immersed in the drug solution in the drug solution container 7.

When the chemical solution contains a sedimentary component, the electromagnetic valve 131 of the stirring mechanism H is opened, and the inert gas for stirring is blown into the chemical solution in the chemical solution container 7.

In this state, the first air spray gun 93 is started to spray the chemical solution in the chemical solution container 7 toward the sample 201. At this time, the air spray gun 93 swings up and down around the horizontal support shaft 94 according to a predetermined operation program. At the same time, the turntable 9 also rotates at a predetermined rotation speed and is moved up and down. Further, if necessary, the entire rotary stage 1 is horizontally moved forward or backward along the rails 17, and Spray gun 93 injection nozzle and sample 201
Keep the distance between and at an appropriate distance.

While the spraying device E1 is operating, the damper 21 and the shutters 49, 61 in the duct 22 are closed, and the fan 23 is operated to prevent the discharge of the chemical vapor to the outside of the spraying chamber A1.
Since the atmosphere composition in the spray chamber A1 is equalized, the tray 20
The chemical liquid is sprayed onto each of the samples 201 above 0 very uniformly and efficiently.

When a predetermined amount of the chemical liquid in the chemical liquid container 7 is sprayed, the weighing device 122 for weighing the chemical liquid container 7 detects this, or by an unillustrated timer or the like, an air spray gun.
The operation of 93 and the stirring mechanism H is stopped.

Accordingly, the shutter 61 of the outlet 5 of the first spray chamber A1
The pull-out rod 59 of the pull-out mechanism 55, which is normally located on the starting end side of the carry-out device C1, is shown by a solid line from the rest position which is shown by the two-dot chain line in FIG. It is rotated toward the operating position where it falls forward, and the claw at the tip is moved to the tray 20.
Hook on the edge of 0. Then, the rodless cylinder 56, which was in the steady forward position, retracts the slider 57 to move the tray 200 on the rotary stage 1 to the belt conveyor 54 of the unloading device C1.
Pull up. At this time, the drive motor 53 of the belt conveyor 54
Is activated, the tray 200 is moved toward its end, and the shutter 61 is closed.

Next, when changing the type of chemical liquid, the control device 300 is switched to the exhaust mode and operates the fan 23.
The damper 21 is opened, and air contaminated with the chemical liquid in the spray chamber A1 is removed by an intake device (not shown) connected to the duct 22.

On the other hand, the liquid medicine container 7 held by the chuck 123 of the liquid medicine container lifting mechanism F is returned to the container stand 73, the rodless cylinder 81 is operated, and this container stand 73 is moved to the end of the guide rail 70. Then, it is transferred onto the ejection station 72 by the cylinder 75. Then, the container stand 73 on which the drug solution container 7 containing another type of drug solution is placed is brought below the drug solution suction portion 96.

In this case, the five drug solution containers 7 accommodated in the container stand 73 are advanced by the stepping cylinder 79 to the distance between adjacent drug solution containers 7 in the normal operating state of the automatic drug solution sprayer. Thus, the chemical liquids in the five chemical liquid containers 7 are sequentially consumed.

While replacing the chemical solution container 7 as described above,
As shown in FIG. 11, the moving cylinder 91 of the movable base 90 is moved to move the frame 93 from the spraying position shown by the solid line in the drawing to the cleaning position shown by the chain double-dashed line. 96 is the cleaning liquid container 125 that normally occupies the lowered position
Is brought directly above.

Then, after moving the frame 92, the rodless cylinder
Since 124 works to move the cleaning liquid container 125 upward, the chemical liquid suction portion 96 is immersed in the cleaning liquid in this container. Then, the air spray gun 93 is activated and the first spraying device is activated.
The inside of the E1 and chemical solution inhalation site 96 is cleaned. This avoids the inconvenience that different types of chemical liquids are mixed in the spraying device E1. The cleaning liquid sprayed from the spray nozzle is collected in the drain 19 and stored in the chemical liquid recovery container 20.

When this cleaning is completed, the frame 92 is returned to the original spraying position, and the electromagnetic valve 131 is opened for a predetermined time to replenish the cleaning liquid container 125 with the cleaning liquid.

The above is the chemical liquid spraying and spraying device in the first spray chamber A1.
Although the cleaning operation of E1 has been described, even in the second spray chamber A2, in parallel with the operation of the first spray chamber A1 or separately from it.
Similar to the first spray chamber A1, the chemical liquid supplied from the chemical liquid suction portion 96 of the first spray device E1 via the hose 8b can be sprayed. In that case, the air supply switching valve 97, the pressure regulating valve 98, and the liquid supply switching valve 99 attached to the first spraying device E1 are switched,
Further, an operating program to be adjusted may be set and set in the control device 300.

Then, if the chemical injection pressure of the second spraying device E2 is set to be sufficiently low by operating the pressure regulating valve 98, the soil will not be blown off when the chemical is sprayed on the pot 202 filled with the cultivation soil. . By reducing the injection pressure in this way, it is not necessary to provide an exhaust means after the spraying in the second spray chamber A2.

The second air spray gun 102 has a front-rear and left-right movement mechanism 100.
By one for each sample 202 placed on the tray 200
One by one is sequentially moved to spray each sample evenly with the drug solution.
