Problems solved by technology
[0003] The existing technology is to install a positioning device on the excavator to realize the positioning of the equipment. Generally, it is low-precision and can only realize the rough position positioning monitoring of the equipment. A few install a high-precision positioning device. This method is to install a high-precision positioning device. The excavator The body is huge, and it is impossible to locate the bucket. The positioning accuracy is not enough, which leads to a large error in the actual excavation position
For the management of the operation area, the traditional mode is to divide the operation area by pulling wires and inserting flags on the working face. The grade control is not perfect, and the accuracy of the grade and proportion of ore excavated cannot be ensured. The geological management software of the production planning department cannot be compared with Positioning monitoring system achieves good docking

Embodiment Construction
[0015] Install the intelligent vehicle-mounted terminal (6) on the rear side of the excavator cab (4), and keep away from water and oil as much as possible. Point A (1) and point B (2) of the high-precision positioning device are installed on any position on the excavator platform (5), as far as possible away from the shovel arm and avoid strong vibration. Point A (1) and point B (2) cannot overlap, and the distance between the two points should be as large as possible. Point A (1) and point B (2) are connected to the intelligent vehicle terminal (6) through a feeder line, and the feeder line adopts a waterproof, wear-resistant, flame-retardant industrial-grade coaxial cable. The installation positions of point A (1) and point B (2) should avoid occlusion to ensure the reception of satellite signals. Angle detection devices J1 (7) and J2 (8) are installed on the side of the shovel arm to avoid oil contamination as much as possible.
[0016] Initialize point A (1), point B (2...

The invention discloses a method for achieving control over the ore output grade through strip mine excavating equipment, and relates to the field of strip mine mining. Two high precision positioningdevices and two angle detection devices mounted on an excavator are utilized to combine with an initialization value of an intelligent car-mounted terminal, the coordinate value of a bucket is accurately calculated by calculating the rotation center of the excavator and the connecting shaft of shovel arms and a platform and combining with a shovel arm angle value; and high precision positioning ofthe bucket and accurate matching of a designated operation area are achieved through combination with an electronic work order generated by grade control supervisor software which is in seamless joint with a geological database, the excavator is precisely guided to conduct production operation, and thus effective ore output grade control is achieved. The method changes a traditional mine excavator production management mode, and solves the problems that the precision of an existing method cannot ensure the grade and the grade control is not perfect. Strong means and basis are provided for oreblending and production dispatching of a mine, and the meticulous level and the automation level of mining production management are improved.
Description
technical field [0001] This case involves the field of open-pit mining, and specifically involves a method for realizing the control of ore output grade by open-pit mining equipment. Background technique [0002] Grade control is an important control index in mine production. Ore grade refers to the content of useful components or minerals per unit volume or unit weight of ore. In mining, the operation area is divided according to the material, ore grade, etc., and the excavator must operate in the specified area. Traditional mine management usually does not control the operation area in a standardized manner, lacks effective management of excavators, mines high-grade ore as low-grade, ore is discharged to the soil yard, and rocks are unloaded to the ore crushing station. Unsatisfactory mine results, resulting in waste of precious grade ore. The resulting dilution is an urgent problem for mines to solve. [0003] The existing technology is to install a positioning device...
