Abstract
The invention provides a hybrid power transmission system of a longitudinal flow cutting threshing device and a harvesting machine. The hybrid power transmission system comprises a driving device, a transmission device, a flow cutting cylinder, a sensing device, a longitudinal axial flow cylinder and a control unit, wherein the driving device comprises an engine, a power generator, a super capacitor and an electromotor; the engine is connected with the power generator; the electromotor is connected with the power generator; the super capacitor is connected with the electromotor and the power generator respectively; the power generator, the super capacitor and the electromotor are connected in parallel on the flow cutting cylinder through the transmission device; and the sensing device is used for measuring SOC (system on chip) values of the super capacitor and therotation speeds of the flow cutting cylinder and the longitudinal axial flow cylinder. By adopting the hybrid power transmission system, when a threshing cylinder is in shortage of operation power, motor driving can act up in time to supplement power; and when the threshing device has excessive energy of the transmission system, the energy can be recycled, so that the problem that the threshing cylinder is unstable caused by sudden change of cereal feeding amounts can be effectively solved, and the problems of blockingand straw tangling caused by sudden increase of cereal feeding amounts can be effectively prevented.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a hybrid power transmission system and method of a cutting and longitudinal flow threshing device and a harvester. Background technique [0002] As an important part of the combine harvester, the threshing device's main function is to thresh and separate the grains from the crop ears. However, due to the uneven planting of grain and the difference in growth, the combine harvester often has a sudden change in the amount of grain fed when harvesting. Since the threshing drum of the combine harvester operates at a constant power, when encountering a sudden change in the feed amount during the threshing process, it is easy to cause problems such as insufficient power of the transmission system of the threshing device, violent oscillation of the threshing drum, clogging of the threshing drum, and breakage of the transmission chain after the clogging. , whic...
