Abstract

The invention provides an automatic material taking method of a bucket wheel machine. The automatic material taking method comprises the following steps that when the rotation circumference bottom of a bucket wheel and the bottom plane of a material taking layer are tangential, the contour line of the material pile outline at the height of the point of tangency between the rotation circumference of the bucket wheel and the material pile slope is obtained; under the condition that the rotation circumference bottom of the bucket wheel and the bottom plane of the material taking layer are tangential, the coordination of the point of tangency of the bucket wheel is determined according to the horizontal rotation track of the bucket wheel around the rotation center of a cantilever, the point of tangency of the contour line and the largest excavation depth of the bucket wheel; and the walking displacement of a material taking machine, the rotation angle of the cantilever and the pitch angle of the cantilever are reasoned out backward, so as to control the material taking machine to take materials automatically. According to the automatic material taking method, by reference to the three-dimensional profile data of the material pile, the action parameters of the material taking machine are reasoned out backward according to the material taking point of tangency, the unmanned material taking control of the bucket wheel machine is realized, the idle sweeping and bucket stalling of the material taking machine can be avoided, and the material taking efficiency is improved to the greatest degree on the premise of not damaging the bucket wheel.

Description

technical field [0001] The invention relates to a method for stacking and retrieving materials, in particular to an automatic retrieving method for a bucket wheel machine. Background technique [0002] At present, bucket wheel stackers and reclaimers are mostly used in steel raw material yards, power plant coal yards, and port bulk cargo yards for loading and unloading of bulk materials. With the improvement of automation level and the application of information and digital technology, the stockyards are committed Unmanned control of the stacker-reclaimer. The 3D model of the stockyard stockpile is the premise of realizing unmanned control. Establishing the 3D model of the stockyard stockpile by laser scanning and other methods is a current research hotspot. However, in terms of stockpile reclaiming technology, most of them use sensor The measurement method is used to correct the action parameters of the reclaimer. The sensor measurement method is only a corrective control ...
