A rice and wheat combine harvester and its cutting width detection device and detection method

Abstract

The invention discloses a rice-wheat combine harvester and a swath detection device and detection method thereof. The rice-wheat combine harvester comprises the swath detection device; the swath detection device comprises a laser sensor, a signal collector and a vehicle-mounted monitor; the laser sensor is installed above a header of the rice-wheat combine harvester and used for acquiring the boundary of a harvested area and an unharvested area of the rice-wheat combine harvester and outputting distance and angle information of a measured object; the signal collector is installed on the rice-wheat combine harvester, connected with the laser sensor through a data bus and used for acquiring and sending distance and angle information data output by the laser sensor; the vehicle-mounted monitor is installed on the rice-wheat combine harvester, connected with the signal collector and used for completing processing, analyzing and displaying on signals sent by the signal collector and data storage. The invention further discloses the swath detection method of the swath detection device.

Description

technical field [0001] The invention relates to an agricultural combine harvester, in particular to a rice and wheat combine harvester and a non-contact cutting width detection device and detection method thereof. Background technique [0002] At present, combine harvesters are developing in the direction of large-scale and high-speed. It will become more and more difficult to use only human vision to identify the harvesting boundary and ensure the consistency of the cutting width when the harvester is operating. When the combine harvester is working in the field, it usually works under the condition of full cutting width, and has reached the rated feeding amount to obtain higher productivity, which requires the driver to have high driving skills and keep full width tracking operation for a long time , the labor intensity of the driver is high, and the field work is dusty, and it is difficult to harvest accurate boundaries with the naked eye. The combine harvester productio...
