[0021] When the utility model is used:
[0022] The pepper seeds are poured from above the seed tank 1, and the seed tank 1 is sealed at the bottom of the seed discharge cavity by the shell, the air suction disc 3, the seed divider 9 and the sealing partition plate 8. The pepper seeds are smoothly sucked into the seed discharge cavity under the action of air suction and the rolling brush 12. The air suction pipe is connected to the outside of the air suction disc 3 to provide suction force for the whole seed sowing unit. The air suction disc 3 is designed as a cavity, and the protruding shaft 301 connected with the seed divider 9 is provided with a strip-shaped hole 303. The three strip-shaped holes 303 are evenly arranged in the 180° upper half of the protruding shaft 301, and the lower half of the protruding shaft 301 is not provided with an air suction hole. The strip-shaped hole 303 is provided with a gauze to prevent the seeds from being sucked into the cavity of the air suction disc 3. Four adjusting bolts 2 are installed on the mounting flange 302 on the side of the air suction disc 3, and the size of the seed discharge cavity can be adjusted by adjusting the tightness of the adjusting bolts 2. The protruding shaft 301 cooperates with the seed divider 9. When the seed hole of the seed divider 9 is combined with the strip-shaped hole 303 in the rotating process, the pepper seeds can be sucked into the seed hole under the action of suction force and the rolling brush 12. When the seed hole of the seed divider 9 rotates to the lower part of the protruding shaft 301, the suction force disappears, and the pepper seeds fall into the seed discharge pipe 4 under the action of gravity, fall above the ground through the opening device 7, and directly complete the covering work in the process of advancing the machine by the rear adjustable covering plate 6, and complete the seed sowing work. The outside of the seed divider 9 is connected with the transmission wheel B10 to provide power source for the rotation of the seed divider 9. In this working process, only the seed divider 9 is rotating, the air suction disc 3 is fixedly installed and will not rotate. The opening device 7 is connected with the seed tube 5, and a long hole is arranged on the opening device 7. The seed sowing depth can be directly adjusted by adjusting the connection position of the long hole and the seed tube 5, and the rear adjustable covering plate 6 is installed on the supporting plate on both sides of the seed tube 5. The covering depth and the covering angle can be adjusted by adjusting the bolt connection position of the supporting plate. The air suction disc 3 and the seed divider 9 in the seed discharge cavity are designed as a taper, which is beneficial to the smooth falling of the pepper seeds into the seed hole, and the seed sowing work can also be completed when there are a small amount of seeds, thereby reducing the waste of the pepper seeds in the seed tank 1.
[0023] The above only describes the preferred embodiments of the utility model, and is not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
