| titleOfInvention | Positive pressure air flow forced seed conveying pipe |
| abstract | A positive pressure air flow forced seed conveying seed guide pipe belongs to agricultural machinery; the cylindrical outer shell is sleeved on the outer part of the cylindrical inner shell, an annular air chamber is arranged between the cylindrical inner shell and the cylindrical outer shell, an annular air passage is arranged between the upper ends of the cylindrical inner shell and the cylindrical outer shell, the annular air chamber is communicated with the inner cavity of the cylindrical inner shell through the annular air passage, a pressure gas inlet communicated with the annular air chamber is formed in the side wall of the cylindrical outer shell, the funnel-shaped inoculation cover is buckled on the upper end part of the cylindrical outer shell, the lower part of the cylindrical inner shell is hermetically provided with a seed guide pipe, the side wall of the seed guide pipe is provided with a plurality of air inlet holes, and the outer wall surface at the; the pipe eliminates the collision and friction between the seeds and the seed guiding pipe and the bounce of the seeds on the soil of the seed bed in the seed conveying process, and has the characteristics of unique, reasonable and simple structure, high seed conveying efficiency, good seed conveying precision, reliable use and simple and convenient regulation. |
