In this embodiment, the communication module is a wireless device respectively connected to the first weighing member 41 and the second weighing member 42, and the communication module can receive the information sent by the first weighing member 41 and the second weighing member 42 and transmit the information to the determining module. The determining module receives information from the first weighing member 41 and the second weighing member 42, converts the information into a first weight value and a second weight value, and compares the second weight value with the first weight value.
The embodiment also provides a belt conveyor blockage detection method, and by adopting the belt conveyor blockage detection system, whether a blockage accident happens to the belt conveyor system can be found in time and processed, so that the service life of the belt conveyor is effectively prolonged, the monitoring of workers is not needed, and the time and labor are saved.
Specifically, the belt conveyor material blockage detection method comprises the following steps:
s1, measuring the weight of the material on the first belt conveyor 1 by the first weighing part 41, and outputting a first weight value;
s2, the second weighing piece 42 measures the weight of the material on the second belt conveyor 2 at intervals of preset time and outputs a second weight value;
s3, the judging module compares the second weight value with the first weight value according to the first weight value and the second weight value received in sequence;
s4, the judging module judges whether the blanking chute 3 is blocked or not according to the comparison result and controls the first belt conveyor 1 to operate or stop.
Alternatively, in step S2, the preset time is not less than 5 seconds. That is, the preset time is longer than the shortest time for the material to flow from the first belt conveyor 1 to the second belt conveyor 2 through the feeding chute 3.
Alternatively, in step S4, when the first weight value is 0, there is no material on the first belt conveyor 1, and the first belt conveyor 1 operates normally. At the moment, the first belt conveyor 1 is unloaded, and the blanking chute 3 is in a normal state.
When the first weight value is not 0 and the second weight value is 0, the blanking chute 3 is blocked, and the judgment module controls the first belt conveyor 1 to stop. At this moment, the blanking chute 3 is completely blocked, the materials on the first belt conveyor 1 are all blocked on the blanking chute 3, the materials flowing to the second belt conveyor 2 are 0, and the machine needs to be stopped immediately to prevent the belt of the first belt conveyor 1 from being worn off by the excessive materials at the blanking chute 3, so that major equipment accidents are caused.
When the first weight value is not 0 and the second weight value is not 0, if the ratio of the second weight value to the first weight value is smaller than a preset value, the blanking chute 3 is blocked, and the judgment module controls the first belt conveyor 1 to stop. At this moment, the part of the discharging chute 3 is blocked, the part of materials on the first belt conveyor 1 can flow to the second belt conveyor 2 through the discharging chute 3, the machine is stopped, the blocked discharging chute 3 can be dredged as early as possible, and the discharging chute 3 is prevented from being blocked completely.
Optionally, the preset value is less than 50%. Preferably, in this embodiment, the preset value is less than 10%. The default value is less than 10% and can guarantee that it is more accurate to detect, prevent that the numerical value of two belt weighers from having the deviation, the numerical value that the material on considering first belt feeder 1 to obtain through first belt weigher simultaneously can be greater than the numerical value that the second belt weigher obtained, because the material reachs first head pulley 11 and gets into when unloading chute 3 has the material loss, it is not good if first head pulley 11's scraper blade deashing effect, or because material viscidity, and material inertia, can cause a little material to take back along with the return belt, cause the material loss.
