Large livestock green feed crushing and mixing device

The invention discloses a smashing and mixing device for green feed for large livestock. The smashing and mixing device comprises a pre-cut feed transferring mechanism, a stepped smashing mechanism, a vortex type auxiliary grinding and mixing mechanism and a breathable antibacterial storage mechanism. The invention belongs to the field of feed crushing, particularly relates to a large livestock green feed crushing and mixing device, and aims to solve the contradictory problem that green feed needs to be crushed (so that fibers are shorter and are more beneficial to digestion and absorption of livestock) and cannot be crushed too finely (which is not beneficial to chewing but hinders digestion and absorption) during crushing of the green feed. A crushing process is divided into three sections by creatively utilizing a segmentation principle (an object is segmented into independent parts), and green feed is crushed from blocks to strips to chips in a gradient crushing manner, so that the overall grinding time i
