A kind of seed metering device equipped with reseeding device

Abstract

The invention discloses a seed metering device provided with a re-seeding device, which overcomes the problem of missed sowing in the prior art. A seed metering device provided with a re-seeding device includes a shell assembly, a seed box assembly, and a seed metering assembly and re-seeding device; the housing assembly includes No. 1 end cover, No. 2 end cover, No. 1 housing, No. 2 housing and No. 3 housing; the seed box assembly includes No. 1 seed box and No. 2 seed box; No. 2 The end cover is installed on the bottom of the No. 1 shell, the No. 2 shell is installed on the right side of the top of the No. 1 shell, the No. 3 shell is installed on the left side of the top of the No. 1 shell, and the No. 1 end cover is installed on the 2 The top of the No. 3 shell and the No. 3 shell, the No. 1 end cover, the No. 2 shell, the No. 3 shell, the No. 1 shell and the No. 2 end cover are connected together by bolts; the seeding assembly and the reseeding device are installed on In the housing assembly, the reseeding device is set on the transmission shaft in the seeding assembly, and one end of the transmission shaft protrudes from the central through hole of the No. 1 end cover; the No. 1 seed box is installed on the No. 1 housing, and the No. 2 The seed box is installed on the No. 2 housing.

Description

technical field [0001] The invention relates to a seed metering device belonging to the technical field of agricultural machinery, more precisely, the invention relates to a seed metering device provided with a reseeding device. Background technique [0002] With the continuous development of agricultural production technology in our country, the precision requirements for seed metering devices are also getting higher and higher. The mechanical seed metering device has a simple structure, easy processing and assembly, and low price. It is suitable for individual rural households and has a wide range of applications. According to different structural forms, it can be divided into: disc type (horizontal disc, vertical disc, inclined disc), socket wheel type, spoon wheel type, finger clip type, etc., mainly relying on seed gravity, population interaction force, centrifugal force Complete filling and seeding. Because the seed filling force is single and the force value is small...

AI Technical Summary

Problems solved by technology

Because the seed filling force is single and the force value is small, it is easy to cause missed sowing; the seed cleaning process mainly depends on external interference and gravity sliding, which is easy to cause missed sowing and reseeding; it is easy to damage the seeds during the seed protection process; the above types The situation is aggravated at high rotational speeds of the seed discs, and therefore, relatively low operating speeds of mechanical seed meters
