The rotation of the eccentric discs realizes the reciprocating pressing of several press-type air pumps. When the press-type air pumps are pressing, they can inflate the inside of the water storage tank through the air inflator pipe, increasing the air pressure inside the water storage tank. This allows the water in the water storage tank to be transported to the spray pipe through the delivery pipe and sprayed out through the nozzle to irrigate the planted orchid seedlings.

[0056] Please refer to this carefully. Figure 1 , Figure 2 Both fixed plates 301 have protruding plates fixed on their surfaces, and both protruding plates have first electric push rods 403 fixed on their lower surfaces.

[0057] Specifically, the automatic planting of orchid seedlings inside the planting nozzle 402 can be achieved by extending and retracting the first electric push rod 403.

[0058] Please refer to this carefully. Figure 1 , Figure 2 The bottom end of the planting nozzle 402 is a conical hollow structure, and the top of the planting nozzle 402 is a cylindrical structure. A discharge ring 405 is hinged to the outer surface of the bottom end of the planting nozzle 402. A rotating frame is fixed on the surface of the planting nozzle 402 and the surface of the discharge ring 405. A second electric push rod 406 is set in the middle of the two rotating frames.

[0059] Specifically, the automatic rotation of the discharge ring 405 can be achieved by extending and retracting the second electric push rod 406, thereby realizing the automatic opening and closing of the planting nozzle 402.

[0060] Please refer to this carefully. Figure 4 , Figure 5 The inner wall of the mounting slot is rotatably provided with a reciprocating threaded column 206, and the bottom surface of the mounting frame 201 is provided with a threaded hole that is threadedly connected to the outer surface of the reciprocating threaded column 206. The upper surface of the movable base 101 is fixed with two symmetrical vertical plates 207, and a limiting rod 208 is fixed in the middle of the two vertical plates 207. The top surface of the mounting frame 201 is provided with a limiting hole that is slidably connected to the surface of the limiting rod 208. One end of the reciprocating threaded column 206 extends to the outer surface of the movable base 101, and one end of the rotating column 302 extends to the outer surface of the fixed plate 301. The ends of the rotating column 302 and the reciprocating threaded column 206 are both fixed with transmission wheels 209, and the surfaces of the two transmission wheels 209 are fitted with transmission belts 2010.

[0061] Specifically, the rotation of the rotating column 302 can drive the rotation of a transmission wheel 209. The rotation of the transmission wheel 209, under the action of the transmission belt 2010, drives the reciprocating threaded column 206 to rotate, thereby causing the mounting frame 201 and the seedling tray 202 to move laterally, thus realizing the switching of the seedling holes.

[0062] In this embodiment, by setting up a seedling delivery mechanism 200, a seedling retrieval mechanism 300, and a planting mechanism 400, the device can pre-fix the seedling tray 202 onto the conveyor belt 204 during actual use. Then, the device is moved. During movement, the two hydraulic rods 307 corresponding to the seedling tray 202 are first activated, driving the mounting plate 308 and the gripper 305 closer to the seedling tray 202. After the gripper 305 is inserted into the seedling hole, the third motor 306 is activated. The rotation of the third motor 306 drives the bidirectional lead screw 30... 9. The rotation of the bidirectional lead screw 309 drives the two L-shaped sliding plates 3010 to move simultaneously towards the center, thereby driving the two grippers 305 to move simultaneously towards the center to clamp the orchid seedling substrate in the seedling hole. Then, the hydraulic rod 307 is activated to retract, achieving the purpose of automatic material removal. After material removal is completed, the second motor 303 is activated to drive the rotating column 302 to rotate 90 degrees. The rotation of the rotating column 302 drives the grippers 305 holding the orchid seedlings to rotate above the planting nozzle 402, and the third motor 306 is activated to reverse, causing the two grippers 305 to separate. This causes the orchid seedling to automatically fall into the planting nozzle 402. During the fall, the planting substrate of the orchid seedling faces downward under the action of gravity, ensuring that the tip of the orchid seedling enters the planting nozzle 402 with its tip facing upward. Then, the first electric push rod 403 is activated, causing the planting nozzle 402 to move diagonally downward and insert into the soil. Finally, the first electric push rod 403 retracts, and at the same time, the second electric push rod 406 retracts, causing the discharge ring 405 to open, so that the orchid seedling is automatically inserted into the soil, achieving the purpose of automatic material collection and automatic planting. Moreover, the second motor... During the rotation of the rotating column 302 driven by 303, the reciprocating threaded column 206 can be rotated under the action of the two transmission wheels 209 and the transmission belt 2010. The rotation of the reciprocating threaded column 206 causes the mounting frame 201 to move laterally, which makes it easier for the gripper 305 to take seedlings from the seedling holes next to the seedling holes that have been taken out. After the last row of seedling holes has been taken out, the first motor 205 can be started to drive the conveyor shaft 203 to rotate, thereby driving the conveyor belt 204 to rotate automatically, so as to facilitate the removal of orchid seedlings from the next row of seedling holes.

Figure 7 , Figure 8The moving mechanism 100 also includes two longitudinal grooves symmetrically opened on the lower surface of the moving base 101, and longitudinal shafts 103 rotatably disposed on the inner walls of the two longitudinal grooves and passing through the longitudinal grooves. Four moving wheels 102 are respectively disposed at the ends of the two longitudinal shafts 103. A spraying mechanism 500 is disposed above the front of the planting mechanism 400. The spraying mechanism 500 includes a spray pipe 501 fixed on the surface of two fixed plates 301, and a plurality of nozzles 502 equidistantly disposed on the lower surface of the spray pipe 501. The spraying mechanism 500 also includes a water storage tank 503 fixed inside the installation groove, and a conveying pipe 504 is disposed on the upper surface of the water storage tank 503. One end of the conveying pipe 504 extends to the inner bottom of the water storage tank 503, and the other end of the conveying pipe 504 extends into the interior of the spray pipe 501.

[0066] Specifically, water can be sprayed from the nozzle 502 on the nozzle 501 onto the planted orchid seedlings to achieve the purpose of irrigation.

[0067] Please refer to this carefully. Figure 7 , Figure 8 A number of press-type air pumps 505 are fixed at equal intervals on the inner wall of a longitudinal groove, and eccentric discs 506 corresponding to the press-type air pumps 505 are fixed at equal intervals on the surface of a longitudinal axis 103.

The end of the air inlet pipe 507 is provided with a filter cover, and the surface of the air inlet pipe 507 is provided with an air inlet one-way valve. The end of the air inflation pipe 508 extends into the interior of the water storage tank 503, and the surface of the air inflation pipe 508 is provided with an air inflation one-way valve.

[0068] Specifically, the rotating wheel 102 can drive the eccentric disc 506 to continuously press the press-type air pump 505, thereby automatically pressurizing the inside of the water storage tank 503, so that the water in the water storage tank 503 can automatically enter the nozzle 501.

[0069] In this embodiment, by setting up a spraying mechanism 500, during the automatic seedling picking and planting process, the movement of the movable base 101 can drive the movable wheel 102 to rotate. The rotation of the movable wheel 102 drives the longitudinal shaft 103 to rotate. The rotation of the longitudinal shaft 103 drives several eccentric disks 506 to rotate. The rotation of the eccentric disks 506 realizes the reciprocating pressing of several press-type air pumps 505. When the press-type air pumps 505 are pressing, they can inflate the inside of the water storage tank 503 through the air inflator 508, increasing the air pressure inside the water storage tank 503. This allows the water in the water storage tank 503 to be transported to the spray pipe 501 through the delivery pipe 504 and sprayed out through the nozzle 502 to spray and irrigate the planted orchid seedlings.
