An object of the utility model is to provide an improve seed metering pipe of seed rate of emergence adjusts through the opening size to seed metering pipe port, has solved the problem that current seed metering pipe is uneven, the cave skew is gone into to the seed.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a seed-discharging tube for improving the rate of emergence of seeds, which comprises a tube body, wherein a ring groove is arranged around the outlet end of the tube body; the inner surface of the annular groove is rotatably connected with a rotating ring; one end of the rotating ring is provided with a plane thread; the rotating ring is matched with two push rods through plane threads; one end of each push rod penetrates through the tube body;

two connecting seats are respectively arranged on the inner side of the pipe body; the pipe bodies are respectively and rotatably connected with baffle plates through connecting seats; one side of each of the two baffles is provided with a sliding chute; and the two baffles are in sliding fit with the push rod through the sliding grooves.

Further, the baffle is of a semi-annular structure; the surface of the baffle is provided with a notch.

Furthermore, the side surface array of the periphery of the rotating ring is provided with rotating arms.

The utility model discloses following beneficial effect has:

the utility model discloses rotate rotatory ring, rotatory ring and two push rod threaded connection adjust the displacement of push rod, it adjusts the opening shape and the size of body port to drive the baffle respectively when two push rods remove, can adjust the speed of seed metering in-process seed metering as required, the seed metering is even, very big improvement the rate of emergence of seedling, the seed is when the whereabouts simultaneously, and because baffle 7 is the semi-annular structure, contained angle between two baffles is oval or duckbilled, thereby reduce the laying height of seed, avoid the seed to splash, guarantee that the seed can be accurate fall into the kind cave from the seed metering pipe, avoid the seed extravagant, the practicality of seed metering pipe has been improved.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
