Abstract

The invention discloses a high copying control system for a harvesting table of a maize harvesting machine. The system is composed of a copying detection device, a harvesting table lifting hydraulic cylinder, a touch screen, a controller, an electro-hydraulic proportional valve, a mechanical contact type guiding mechanism, a steering hydraulic cylinder, a steering detection sensor and the like. One end of the copying detection device is installed on a protecting tip at the front end of the harvesting table, the other end of the copying detection device is connected with the harvesting table through a chain, and during work, a copying rod makes contact with the ground through dead weight. The copying rod of the copying detection device and an angular displacement sensor rotary shaft rotate synchronously. When the high copying control system for the harvesting table of the maize harvesting machine carries out high copying work, the copying rod rotates around a base shaft hole along with surface relief, an angular displacement sensor feeds changed angle values back to the controller, the controller controls and adjusts actions of the electro-hydraulic proportional valve and the harvesting table lifting hydraulic cylinder, lifting of the harvesting table is achieved, and high copying actions are completed.

Description

technical field

[0001] The invention relates to an agricultural machine, in particular to a height profiling system and a height profiling method for a harvesting platform of a corn harvester. Background technique

[0002] my country is a large agricultural country. The automation and intelligence of agricultural machinery and equipment is the premise and foundation for realizing the scale of modern agricultural farming in our country, and has broad development prospects. Although my country has made remarkable achievements in the mechanization of agricultural equipment, it is still in its infancy in terms of automation and intelligence. Corn harvester is a large-scale agricultural harvesting equipment. When working in the field, the driver must drive the machine carefully on the one hand, and pay close attention to the stubble height, feeding amount and engine working conditions on the other hand. Long-term mechanical operation will Increase driver fatigue and reduce harve...
