Seed winnowing assembly and pasture variety screening device

Abstract

The invention relates to the technical field of animal husbandry, in particular to a seed winnowing assembly and pasture variety screening device. The seed winnowing assembly comprises a rack, wherein a circulating barrel is fixedly installed on the rack, a discharging opening is formed in the top of the circulating barrel, a material distributing hopper is installed at the discharging opening, a fixing frame is fixedly installed on the side wall of the circulating barrel, a second lead screw is rotatably mounted in the fixing frame, a lifting block is in threaded connection with the second lead screw, an upper air blower is fixedly mounted on the side wall of the lifting block, pasture seeds to be treated are put into a screening box, the pasture seeds are conveyed to a circulating feeding port through a conveying belt and enter a circulating cylinder, the pasture seeds are conveyed to the screening box through a conveying belt, the pasture seeds are flatly laid in the material distributing hopper through a slicking assembly, the pasture seeds can conveniently fall down through dispersing holes, impurities with small density mixed in the pasture seeds are separated out through the upper air blower and a lower air blower, the upper air blower is driven by a third motor to move up and down, the lower air blower is driven to swing in a reciprocating mode, and the air blowing range is expanded.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a seed winnowing component and pasture variety screening equipment. Background technique [0002] Animal husbandry refers to the production sector of raising livestock and poultry to obtain animal products or draft animals by means of grazing, captive breeding or a combination of the two. Grass is the basis for the development of livestock production, especially the production of grass-fed livestock. Grass not only contains various nutrients necessary for livestock, but also contains crude fiber which is especially important for maintaining the health of ruminant livestock, which cannot be replaced by grain and other feed. High-quality forage can fully meet the nutritional needs of general livestock. If it is not in the production or fattening period, it is generally not necessary to supplement the concentrate.
