The invention relates to a double-wheel single-hinging profiling ground wheel
assembly and belongs to
agricultural machinery. A connecting plat is hinged on a beam frame, a
power output shaft is fixedly arranged on a driven chain wheel and is inserted in the connecting plate in a matching manner, two ends of a bidirectional hydraulic oil cylinder are respectively hinged on the beam frame and the connecting plate, a ground wheel bracket is hinged on the lower side part of the connecting plate, central shafts are fixedly arranged on a driving chain wheel and an overrunning
clutch and are inserted into the connecting plate and the ground wheel bracket in a matching manner, a first driven chain wheel and a second driven chain wheel are fixedly arranged on the exterior of the overrunning
clutch, a first driving ground wheel and a second driving ground wheel are arranged on two side parts of the ground wheel bracket, a first driving
tower chain wheel and a second driving
tower chain wheel are respectively fixedly arranged on a first driving ground
assembly and a second driving ground
assembly, a main driving chain is sleeved on the driven chain wheel and a driving chain, a first drivingchain and a second driving chain are respectively sleeved on the first driving
tower chain wheel and the first driven chain wheel, and a second driving tower chain wheel and the second driven chain wheel. The double-wheel single-hinging profiling ground wheel assembly disclosed by the invention has the advantages of simple, novel and reasonable structure, enough driving power for operation, good profiling performance and reliability for using.
