The invention relates to a seed
distributor of a pneumatic conveying type wheat seeding
machine, and belongs to the technical field of seeding devices of
agricultural machinery. The seed
distributor of the pneumatic conveying type wheat seeding
machine comprises a seed
distributor body, a flow distribution cover, seed guide
pipe connecting ports, a seed guide wall, a gas and
solid mixing wall, anda seed conveying
pipe connecting port, wherein the flow distribution cover is arranged at the center position of the upper end of the seed distributor body; the upper end surface of the seed distributor body is provided with the multiple seed guide
pipe connecting ports, the upper end surface of the seed distributor body is connected with one end of a first side wall, the other wall of the firstside wall is connected with one end of an inclined side wall, and the inclined side wall is used as the seed guide wall; and the other end of the inclined side wall is connected with the gas and solidmixing wall, the other end of the gas and
solid mixing wall is connected with the side wall of the seed conveying pipe connecting port, and the inner surface of the gas and
solid mixing wall is uniformly distributed with annular bulges. The seed distributor involved in the invention has the beneficial effects that the uniformity in seed discharging is good; the breaking rate of seeds is low; thecost is low; and the reliability is high.
