HOPPER UNLOADING APPARATUS Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has horizontal auger coupled to drive and connected through kinematic connection to rotary discharge auger. Mechanism for rotating discharge auger from transport position to operating position and vice versa has double-acting piston-type main hydraulic cylinder and auxiliary double-acting hydraulic cylinder. Both hydraulic cylinders are controlled from single hydraulic distributing section. Working cavities of hydraulic cylinders and rod cavities are communicated via T-unions. Kinematic coupler has telescopic cardan shaft, drive shaft disposed in parallel with axis of discharge auger outside its pipe, and chain transmission. Such construction provides increased angle of rotation of discharge auger and, thus, more complete and controlled charging of vehicle without moving it relative to combine during discharge of grain from hopper. EFFECT: simplified construction and enhanced reliability in operation. 2 cl, 3 dwg
