Self-adaption regulation system for threshing segregation loads of tangential flow and longitudinal axial flow devices

Abstract

The invention provides a self-adaption regulation system for threshing segregation loads of tangential flow and longitudinal axial flow of a combined harvester and a regulation method. The regulation system mainly comprises a drift loss monitoring device, a grain crashing rate monitoring device, a tangential flow concave exit gap regulation device, a shake plate load monitoring device, a return stroke plate load monitoring device and an online monitoring control system. Through real-time monitoring of a grain crashing rate, a drift loss rate, a tangential flow concave exit gap, a tangential flow drum rotation speed and a longitudinal axial flow drum rotation speed, and according to differential signals of an impact sensor and an inertia force sensor, a load ratio of a tangential flow threshing segregation device and a longitudinal axial flow threshing segregation device can be computed; the tangential flow concave exit gap, the tangential flow drum rotation speed and the longitudinal axial flow drum rotation speed are regulated, so that the threshing segregation load ratio of the tangential flow threshing segregation device to the longitudinal axial flow threshing segregation device could stay in a rational scope; harvesting requirements for different varieties of crops featured by difficult threshing or easy threshing could be satisfied; and optimum threshing ability and high adaptability can be maintained.

Description

technical field [0001] The invention belongs to the field of combine harvester threshing and separation devices and self-adaptive control, in particular to an self-adaptive control system for threshing and separation loads of cutting flow and longitudinal axial flow devices. Background technique [0002] At present, combine harvesters have been developing towards large-scale, automation, and intelligence. From the perspective of development, the harvesting performance and automation and intelligence of combine harvesters have become an important indicator of modern agriculture. In recent years, with the development of my country's agricultural machinery production and the influence of cross-regional harvesting, the demand for combine harvesters in rural areas has gradually developed from small to medium and large. This urgently requires the corresponding online monitoring system to monitor the working status of key components, so that the driver can control the working statu...

Problems solved by technology

However, the focus of this invention is on the clogging problem, and there is no corresponding monitoring device to monitor performance indicators such as grain breakage rate and entrainment loss rate in real time. In addition, there is still a lack of specific proposals for the corresponding regulatory structure and specific implementation plans
