[0004] There is a hand-held sowing device in the existing market, which can only be used for sowing the seeds of a specific plant, and cannot be suitable for sowing seeds with a large difference in grain size at the same time; and the sowing duckbill in the existing sowing device such as Figure 8 As shown, it includes two hollow cones, the two cones are hinged at the discharge port of the sowing device. When in use, the two cones are pressed down to break the soil, and then the two cones are separated by pulling the cable The cone is used to realize the seeds entering the soil between the two cones. The stability of the cable driving mode of the cone of this structure is poor, and the two cones are both hollow and hinged at the discharge port of the sowing device. After pulling the cable 800 to separate the two cones, an open blanking space is formed between the two hollow cones, between the cone and the discharge port, so the seeds often leak out from the outside of the cone without directly Falling between two cones, its use effect is poor

Abstract
The invention discloses a seeding device, which comprises a shell, a first partition plate, a pressure bar, a spring, a sowing nozzle, a soil poking block, first connecting rods, gears, a rack and a seed metering mechanism. The first partition plate is disposed in the shell, and divides the inner cavity of the shell into an installation cavity and a seed metering cavity, the sowing nozzle is fixed on a discharge port, the soil poking block is hinged to a discharge port side wall, the two gears are rotatably disposed in the seed metering cavity and are engaged with each other, the upper ends of the two first connecting rods are respectively hinged to the two gears, the lower ends are respectively hinged to the sowing nozzle and the soil poking block correspondingly, the pressure bar is movably inserted into the installation cavity, and the upper end and lower end of the pressure bar both pass through the side wall of the shell and extend out of the shell, the spring sleeves the pressure bar, and the upper end and lower end of the spring respectively abut against the inner wall of the installation cavity and the pressure bar correspondingly, the rack is fixed on the pressure bar, and is engaged with one of the gears, the seed metering mechanism is disposed in the seed metering cavity, and one end of the seed metering mechanism is connected to the pressure bar. The seeding device provided by the invention has the advantages of wide applicability and good stability.
