FIELD: agricultural engineering. ^ SUBSTANCE: lump crusher has two balloons, each made in the form of end disks mounted on shaft and elastic closure fixed thereon. Upper balloon is secured on shaft by means of coil springs coaxially positioned for angular and axial displacement relative to shaft. One end of each spring is fixed on drive shaft and other end of each spring is fixed on end disks of balloon. At least upper balloon is coupled to drive shaft by means of spiral coils of end disks. ^ EFFECT: increased efficiency and improved operating characteristics of lump crusher. ^ 3 dwg |
