Dry-type frication slice power output device applied to farm machinery and control method for same

Abstract

The invention provides a dry-type frication slice power output device applied to farm machinery and a control method for the same. The dry-type friction slice power output device comprises a shell body and an output shaft, wherein a belt wheel is connected to the end of the output shaft remote from the shell body; a gear ring, a friction slice, a pressure bearing device, and a compressing device containing a plunger, an oil cylinder base and a working chamber are disposed in the shell body; the pressure bearing device comprising a pressure bearing plate and a pressure plate is located between the gear ring and the output shaft; a shaft pin coated by a reset spring is disposed on the pressure bearing plate, and the friction slice is disposed between the pressure bearing plate and the pressure plate; and a control system outputs and transmits pressure to the working chamber so as to form compression force, the compression force makes the plunger generate axial motion so as to transmit the compression force to the pressure plate and the pressure bearing plate by a bearing II, the friction slice is meshed, power is transmitted to the output shaft, and power output is completed. According to the invention, the dry-type friction slice is used, and the compression force is formed by a fluid; the control system controls the power output; combination and cutting of working device power can be achieved; the system is reliable; and the system fault rate can be reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a dry-type friction plate power output device for agricultural machinery and a control method thereof. Background technique [0002] With the development of rural economy and agricultural mechanization, the scope of agricultural machinery operations continues to expand, and a large number of agricultural machinery and tools that work with power output devices have emerged, such as rotary tillers, sprayers, harvesters, air-suction seeders, and melon seeds. machine and straw crushing and returning machine, etc. The application of these machines not only reduces the labor intensity of farmers, improves the quality of work and comprehensive benefits, but also improves the utilization rate of agricultural machinery and increases the income of operators. However, the working device of the agricultural machinery needs power input only when it is working, and the power ...
