A front-arranged four-wheel-drive maize harvesting
machine transmission mechanism of a peeling
machine is structurally characterized in that a
diesel engine is installed in the middle of the whole
machine. A left belt wheel of the
diesel engine is connected with a walking
clutch through a triangular belt, and a transmission gear installed at the right end of a
clutch shaft is meshed with a gearbox power input gear. A right belt wheel of the
diesel engine is connected with a combination grouping belt wheel installed at the input end of a middle transmission box through a combination grouping triangular belt, and a harvesting
clutch wheel is installed on a frame in front of the combination grouping belt wheel. A steering driving axle is connected with a rear output shaft of a walking gearbox through a transmission shaft. A power input chain wheel of a returning-to-field machine is connected with a left driving chain wheel installed at the left output end of the middle transmission box through a chain. An
auger power input chain wheel and an
elevator power input chain wheel are connected with a right driving chain wheel installed at the right output end of the middle transmission box through a chain. A header power input chain wheel is connected with a right transmission chain wheel through a series of transmission chain wheels and chains, and a left transmission chain wheel is connected with a
power output chain wheel installed at the right output end of the middle transmission box through a chain. By means of the structure, the whole machine
transmission system is simple and reliable, low in cost and complete in function.
