摘要: A vehicle-mounted sowing device includes a continuously rotating drum, centered on horizontal shaft, axially divided into pick-up chamber and distributing chamber, the latter being peripherally subdivided multiplicity of outwardly open compartments which communicate with at zenith drum an outlet nadir thereof. The peripheral wall has generally radial bores leading to suction manifold via arcuate slot surrounds over about half its circumference, terminating where seeds or kernels introduced this bottom carried by in respective top are released from their seats drop through connecting chute chamber. Stationary strippers sweep vicinity just ahead point release dislodge supernumerary kernels; brush and/or scraper beyond serve detach seed fragments push them deeper preferably widen toward manifold. is formed beveled face housing juxtaposed similar provided inlets seat-forming
