Abstract

The invention relates to the technical field of outgoing quality detection of harvesting machineries and provides a lifting speed detection device and method of combine harvester headers, wherein the lifting speed detection device is simple in structure, high in precision and capable of performing detection automatically. The lifting speed detection device adopts the laser ranging technology and the computer measurement and control technology and comprises a signal collection machine part, a data collector and a computer, wherein the signal collection machine part is connected with the computer through the data collector. The lifting speed detection device adopts non-contact type measurement and can be installed on the headers of different combine harvesters to detect lifting speed. Workers utilize an angle adjustment bolt to level a sensor panel and perform self-calibration on distance data collected by a laser ranging sensor through a level self-calibration instrument to achieve precise measurement. Collecting, processing and storing of speed data can be performed through a computer test platform, and the lifting speed detection device can be connected with an external device to print reports. By means of the technical scheme, reference can be provided for detection of other technical parameters, such as static settlement amount of the headers.

Description

technical field [0001] The invention relates to the technical field of delivery quality inspection of harvesting machinery, in particular to a device and method for detecting the lifting speed of a header of a combine harvester. Background technique [0002] The lifting speed of the combine harvester header is a performance parameter of the whole machine of the harvester, which plays a vital role in the harvesting operation. Article 5.3.1.1 of JB / T5117-2006 "Technical Conditions for Full-feed Combine Harvesters" stipulates that the lifting speed should not be lower than 0.2m / s, and the lowering speed should not be lower than 0.15m / s. For the test method of header lifting speed detection, JB / T7316-2005 "Grain Combine Harvester - Hydraulic System Test Method" 5.2.1 clearly stipulates that the combine harvester is parked on a flat ground, and the header is controlled to rise and fall. Control the valve handle or joystick to raise the header from the lowest position to the high...
