Description

technical field [0001] The invention relates to a power transmission device for agricultural machinery, which is a wheat [0002] A harvester and a harvesting method belong to the technical field of hydraulic transmission of agricultural machinery. Background technique [0003] In the stepless automatic variable speed transmission, the hydraulic transmission has been paid more and more attention, mainly because it has a series of advantages, such as: realizing continuous and smooth stepless speed change in the range of positive and negative rotation, large energy capacity, small size, light weight, and low moment of inertia. Small size, quick start, flexible action, etc., hydraulic transmission has been widely used in agricultural vehicles, construction machinery, etc. However, in the case of high-power transmission, pure hydraulic transmission has disadvantages such as low efficiency and large volume and weight of hydraulic components. However, under the existing technical...

AI Technical Summary

Problems solved by technology

However, in the case of high-power transmission, pure hydraulic transmission has disadvantages such as low efficiency and large volume and weight of hydraulic components. However, under the existing technical conditions, the performance of hydraulic components is limited, and it is very difficult to develop high-power hydraulic components with good performance. , so there is a transmission form that combines hydraulic transmission and mechanical transmission. After hydraulic transmission, there are two improved forms of mechanical transmission in series and parallel connection of mechanical transmission and hydraulic transmission. The way of combining mechanical transmission into hydraulic transmission improves the transmission system. Excellent transmission performance and transmission efficiency, work efficiency has also been improved to a certain extent

[0004] The existing wheat harvester has relatively single function, can only harvest wheat, and cannot carry out multiple functions at the same time, the production efficiency is not high, and its structure is also relatively complicated, and the production cost is also relatively high, which is not conducive to popularization and use
