Problems solved by technology
However, this screening method can only roughly classify coal blocks, and cannot accurately obtain the volume of coal blocks, so as to calculate the density of coal blocks
In addition, this screening method will also cause damage to the coal lumps, and large-volume coal lumps are easily split into small-volume coal lumps under vibration.

The invention belongs to the technical field of volume dynamic measurement and discloses a volume dynamic measuring device based on laser scanning radars and a measuring method thereof. The volume dynamic measuring device based on the laser scanning radars comprises a conveying belt. A first laser scanning radar, a second laser scanning radar and a third laser scanning radar are correspondingly installed at the upper side, the left side and the right side of the conveying belt and are in the same vertical plane. The first laser scanning radar faces a conveying belt plane vertically, and both the second laser scanning radar and the third laser scanning radar face the conveying belt plane horizontally. The rotating shaft of the driving motor of the conveying belt is fixedly equipped with an incremental rotary encoder. The first laser scanning radar, the second laser scanning radar and the third laser scanning radar are electrically connected with an industrial control machine through a switch. The incremental rotary encoder is electrically connected with the industrial control machine through a data collection card.
Description
technical field [0001] The invention belongs to the technical field of volume dynamic measurement, in particular to a volume dynamic measurement device and a measurement method based on laser scanning radar. Background technique [0002] In many scientific researches and industrial productions, it is often necessary to know the volume parameters of related objects. However, when the measured object has characteristics such as time-varying, toxic, and explosive properties, it is inconvenient to measure directly manually for the sake of safety. For example, in the process of sorting and classifying coal, it is necessary to dynamically measure the volume of coal, so that it can be automatically classified according to its volume or combined with its mass to calculate its density. At present, the method of sorting coal blocks according to volume is mainly the vibration screening method, that is, according to the different movement directions of coal blocks when they vibrate, co...
