[0002] Plug tray seedling technology is a modern seedling technology that uses light-substrate soilless materials such as peat and vermiculite as seedling substrate, mechanized precision sowing, one seed per hole, and one-time seedling growth. The steps include: 1. Substrate preparation, mixing peat, vermiculite, perlite and preventive fungicides in a certain proportion; 2. Tray loading, loading the evenly mixed substrate into the hole tray; 3. Pressing holes, using a hole puncher to press holes, the pressing hole depth is generally about 2 cm; 4. Sowing, sowing seeds into the holes, generally one seed per hole; 5. Covering with soil, spreading the substrate evenly on the hole tray, and the thickness of the covering soil is determined by the size of the seeds; 6. Watering, using a watering can or shower head to water thoroughly in time, and the amount of watering should be based on the water seeping out of the water holes at the bottom of the hole tray; At present, when carrying out plug tray seedling cultivation, most of the hole pressing and sowing operations are performed manually, which not only consumes a lot of manpower and time, but also has low efficiency.

[0003] In order to solve the above technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN202322495413.9 is a needle-suction seeder, including a seeder frame, a transmission mechanism is installed on the seeder frame, a puncture mechanism is installed on the top of the seeder frame, and an automatic feeding mechanism is installed on the seeder frame and on one side of the puncture mechanism.

The electric telescopic column is used to perform reciprocating telescopic motion, so that the end of the hollow sowing needle is placed in the inner cavity of the sowing tube.

A sliding hole is provided on the slider 443, and a thread is provided in the sliding hole. The sliding hole is threadedly connected to the screw 442, so that the slider 443 is driven to move on the screw 442 by the rotation of the screw 442, and one end of the seed sweeping cross bar 444 is fixed to the slider 443 The top of the seed-sweeping scraper 445 is fixedly connected to the bottom end of the seed-sweeping cross bar 444, and the bottom end is used to sweep the seeds in the seed tray 432 flat. The two seed-sweeping pieces 446 are respectively installed on both sides of the seed-sweeping cross bar 444, and one end of each seed-sweeping piece 446 is arc-shaped and close to the inner side of the feeding end of the seed tray 432, so as to sweep the seeds located at the feeding end of the seed tray 432 to the other end. In this way, in the process of the seed-sweeping cross bar 444 moving back and forth in the seed tray 432, the seed-sweeping scraper 445 can quickly sweep the seeds to the gap, so that the gap in the tray after the seeds are sucked by the hollow sowing needles 426 can be quickly restored, ensuring that each hollow sowing needle 426 can absorb sufficient seeds each time.

[0044] Example 1, working process of the seed sweeping component 44

[0045] When each hollow sowing needle 426 absorbs seeds from the seed tray 432, a gap will be left at the absorption point. At this time, the slider 443 moves back and forth on the screw 442 under the drive of the sweeping motor 441, so as to drive the sweeping scraper 445 to move back and forth in the seed tray 432 through the sweeping cross bar 444. In this process, the sweeping scraper 445 will sweep the seeds around the gap into the gap, so that the gap can be quickly restored.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
