VIBRATING SCREEN DRIVE FOR HARVESTER

WIPO Patent Application WO/2022/141993

A1

A vibrating screen (H) drive for a harvester. The vibrating screen drive comprises two bearing seats (2g), a transmission shaft (3g), two eccentric bearings (4g) and a drive wheel (5g). The two bearing seats (2g) are respectively correspondingly fixed to side wall faces of two symmetrical supporting beams at a tail end of a rack, an outer spherical bearing is mounted in any bearing seat (2g), and two ends of the transmission shaft (3g) are fixed in the outer spherical bearing, respectively. The two eccentric bearings are respectively fixed at the two ends of the transmission shaft (3g) in a mirror image manner, one end of a vibrating screen is fixed on the two eccentric bearings (4g), the other end of the vibrating screen is arranged on the rack by means of a reciprocating guide structure, and the drive wheel (5g) is fixed at one end of the transmission shaft (3g) and is suitable for being driven by a driver of a harvester to drive the transmission shaft (3g) to rotate. The bearing seats (2g) are directly fixed on the supporting beams of the rack, transition connection is avoided, and the rack directly bears the gravity of the vibrating screen and an inertia acting force of reciprocating motion of the vibrating screen, such that vibration of the vibrating screen is more stable.
