Transverse rotation stripping roller spike stroking type mechanical-negative pressure airflow alfalfa seed collection table

Aiming at the problems of large loss, low cleanliness and the like of current alfalfa seed harvesting, the invention provides a transverse rotation stripping roller spike stroking type machinery-negative pressure airflow alfalfa seed collection table which comprises a seedling pressing nose, a bracket assembly, an inner container, a transmission device, a hydraulic device, a seed transportation device, a stripping roller, a feeding auger and a deposition area inclined plate, plants are pressed by a seedling pressing nose at the front end of the device, so that the bent alfalfa plants, the stripping roller, the inclined plate of the deposition area and the inner container form a relative sealing system, and meanwhile, the stripping roller rotates at a high speed to generate negative-pressure rotary airflow to absorb alfalfa seeds stripped by stripping and spike stripping plate teeth into an inner cavity of a collection table to complete efficient collection. The teeth of the stripping and spike stroking plate
