Specific implementation method:
[0013] Example: Figure 1-2 As shown, a device for laying seeds on a hydroponic forage seedling tray comprises a frame 1, a seed storage bin 2, a weighing hopper 3 and a placing table 4; the seed storage bin 2 is arranged above the frame 1, a first gate valve 5 is arranged on the discharge port of the seed storage bin 2, a weighing hopper 3 is movably arranged on the frame 1 below the seed storage bin 2, and a second gate valve 6 is arranged on the discharge port of the weighing hopper 3; a placing table 4 is arranged on the frame 1 below the weighing hopper 3.
[0014] Tracks 7 are correspondingly fixed on the frames 1 on both sides below the seed storage bin 2, a fixed frame 8 is movably arranged on the track 7 through a rotating wheel 9, and a weighing hopper 3 is connected to the bottom of the fixed frame 8 through a weighing sensor 10; transmission shafts 11 are rotatably arranged on both sides of the track 7, and corresponding sprockets 12 are respectively sleeved on the two transmission shafts 11, and chains 13 are sleeved on the two sprockets 12, and the disconnected ends of the chain 13 are respectively fixed to the two ends of the fixed frame 8; a driving motor 14 is fixed on the frame 1, and the output end of the driving motor 14 is drivingly connected to one end of one of the transmission shafts 11.
[0015] A vibration table 15 is arranged on the placement table 4 . The bottom of the vibration table 15 is connected to the placement table 4 via a plurality of springs 16 . A vibration motor 17 is fixed to the bottom of the vibration table 15 . A placement slot 151 is provided on the top of the vibration table 15 .
[0016] A contact sensor 18 is arranged in the placement groove 151; the signal output ends of the weighing sensor 10 and the contact sensor 18 are connected to the signal input end of the controller 19 through signals, and the signal output end of the controller 19 is connected to the signal input ends of the first gate valve 5, the second gate valve 6, the drive motor 14 and the vibration motor 17 through signals.
[0017] Working principle:
[0018] The clean seedling tray is sent to the placement groove 151, and the contact sensor 18 in the placement groove 151 transmits a signal to the controller 19. The controller 19 controls the first gate valve 5 to open, and the seeds in the seed storage bin 2 fall into the weighing hopper 3. The weighing sensor 10 transmits a signal to the controller 19. When the seeds meet the requirements, the controller 19 controls the first gate valve 5 to close, delays for 5s, controls the drive motor 14 to start, and controls the second gate valve 6 to open. The weighing hopper 3 moves forward with the chain 13, and the seeds fall and spread on the seedling tray. After moving to the specified distance, the drive motor 14 starts to start, and the second gate valve 6 is opened. The weighing hopper 3 moves forward with the chain 13, and the seeds fall and spread on the seedling tray. After moving to the specified distance, the drive motor 14 starts to start, and the second gate valve 6 is opened. The motor 14 reverses, and when the weighing sensor 10 returns a signal that there are no seeds in the weighing hopper 3, the controller 19 controls the second gate valve 6 to close, and the weighing hopper 3 returns to the bottom of the discharge port of the seed storage bin 2, the driving motor 14 stops, and at the same time controls the vibration motor 17 to turn on, and the vibration table 15 vibrates to drive the seedling tray to spread the seeds inside, so that the seeds in the seedling tray are evenly laid. After vibrating for a certain period of time, the controller 19 controls the vibration motor 17 to close, and the seed laying in the seedling tray is completed without manual labor, which saves time and effort, saves labor costs, and improves the seed laying efficiency.
