The invention relates to the technical field of
crop sowing, and discloses proportion-adjustable double-seed-metering equipment for mixed
sowing of barley and common vetch or
vicia villosa, the proportion-adjustable double-seed-metering equipment comprises an equipment main body, a rack, a ditching plate, a soil covering wheel, a
sowing mechanism and a
material storage assembly, a discharging frame is internally provided with a
sieve plate, a filter plate, a moving structure, a pressing structure, a material turning structure and a material guide
assembly, a two-way motor II of a moving structure drives a moving plate to drive a
sieve plate and a filter plate to perform vibration screening, a vertical plate and a convex block of a pressing structure assist in crushing adhered seeds, an arc plate and a cleaning
brush of a material turning structure prevent accumulation and hole blockage, and a material guide
assembly realizes intermittent discharging; a seeding mechanism comprises a shell, a bean tray, a wheat tray and an adsorption assembly; a two-way motor I drives the bean tray and the wheat tray to rotate; the fan adsorbs the seeds through the air
pipe to
discharge the seeds, and the valve body of the blanking
pipe adjusts the mixed sowing proportion. According to the equipment, the seed purity and the seeding uniformity are improved, various planting requirements are met, and the emergence rate and the yield are guaranteed.
