Method for weighing belt conveyor and weighing device

Abstract

The invention relates to a method for weighing a belt conveyor, which is characterized in that a weighed area of the belt conveyor is divided into a plurality of weighing segments, a belt of each weighing segment is supported by a group of cantilever type weighing sensors, each group of cantilever type weighing sensors send acquired weighing signals to a weighing control instrument, the weighing control instrument carries out analysis and processing on the weighing signals acquired by each group of cantilever type weighing sensors according to an inclination angle of the belt conveyor, and the accumulative amount of the weight of materials conveyed by the belt conveyor at a certain time period is acquired. The invention further relates to a belt conveyor weighing device, which is characterized in that one end of cantilever type weighing sensor is connected with a weighing segment bracket, the other end of the cantilever type weighing sensor is connected with a foundation supporting beam, the weighing segment bracket is provided with more than one supporting roller, and a rotation axis supporting a transmission roller is parallel to a stress strain axis of the cantilever type weighing sensor. By adopting the weighing method and the weighing device, the state that the sensor is uneven in stress degree can be enabled to be improved to a great extent, and the weighing and measuring accuracy can be improved.

Description

technical field [0001] The invention relates to sensor weighing technology, in particular to a weighing method and a weighing device of a belt conveyor. Background technique [0002] At present, load cells are usually used for weighing in belt conveyors. An existing way of using sensors to feed and weigh the belt conveyor is to install a number of cantilever-type load cells below the entire belt conveyor, and each cantilever-type load cell will jointly bear the weight of the entire belt and the materials on it. Weight, and the obtained weighing signal is transmitted to the weighing control instrument, and the weighing control instrument processes the obtained signal to obtain the weight of the conveyed material in a certain period of time. The disadvantage of this existing method is: when the belt conveyor is at a certain inclination angle, the pressure on the sensor at the top is small, and the pressure on the sensor at the bottom is the largest, which causes the sensor to...
