Problems solved by technology

However, there is no reliable and effective detection method for whether there is material on the belt conveyor, and where the material head and tail of the material flow are. Therefore, domestic belt conveyor transportation companies generally do not have a reliable and low-cost material flow tracking system.
Most belt conveyor transportation systems generally rely on a limited number of industrial cameras to observe and estimate, or rely on manual observation when refueling is required, and notify the time of refueling or dumping through the walkie-talkie, so that automatic detection and tracking of material flow cannot be achieved
[0004] At present, there are also material flow detection devices installed on belt conveyors. There are two main types of devices installed by various raw material factories on belt conveyors for material flow detection: one is a metering electronic scale, and its main function is to monitor the conveyed materials. Metering, but due to its large equipment structure, high precision requirements, and relatively high investment costs, it is not suitable for ordinary logistics monitoring. At present, it is mainly used to measure the conveyed materials; and the other is scraping The main function of the plate-type material flow detection device is to monitor the flow change of the material. The scraper-type material flow detection device is generally installed above the tail car belt. When the material is conveyed on the belt conveyor, the material and the scraper-type material flow detection device The contact of the scraper makes the scraper tilt and presses the contact of the detection device, indicating that the belt conveyor is running with material, and when the scraper is naturally vertically downward, the scraper and the contact of the detection device are not in contact, indicating that the belt conveyor is in idling operation state, but the problems existing in the scraper type material flow detection device in the prior art are: (1) When the material flow on the belt conveyor is too low or the material flow on the belt conveyor is intermittent, the detection effect of the scraper type material flow detection device is quite inaccurate , thus affecting the monitoring effect during the operation of the belt conveyor; (2) The scraper type material flow detection device is prone to failure due to long-term operation and has low reliability, high failure rate, short service life, low maintenance cost and strength Large, currently rarely used
This application can detect whether the belt is running with load or no load, and realize the sprinkler device on demand, but the structure of the application is complex, the production cost is high, and the operation and maintenance costs are high

Embodiment 1

[0038] A belt conveyor material flow detection system for transporting materials in this embodiment is suitable for continuous material flow detection. It includes conveyor belt 1, side idler 2, horizontal idler 3 and belt conveyor bracket 4, the side idler 2 and horizontal idler 3 are fixed above the belt conveyor bracket 4, and the conveyor belt 1 is located on the side support Above the roller 2 and the horizontal idler 3, all the horizontal idlers 3 in the material flow detection system of the belt conveyor are installed with eccentric idlers at intervals. In this embodiment, one is installed every two existing circular horizontal idlers 3 Eccentric idler, the eccentric idler is an elliptical roller 303, the cross-sectional structure of the elliptical roller 303 is as follows figure 2 As shown in (a), the eccentricity of the cross-section of the elliptical roller 303 is 0.10, and the vibration sensor 5 is fixedly connected to the belt conveyor bracket 4 on which the ecc...

Embodiment 2

[0045] A belt conveyor material flow detection system for transporting materials in this embodiment is suitable for intermittent material flow detection. It includes conveyor belt 1, side idler 2, horizontal idler 3 and belt conveyor bracket 4, the side idler 2 and horizontal idler 3 are fixed above the belt conveyor bracket 4, and the conveyor belt 1 is located on the side support Above the roller 2 and the horizontal roller 3, all the horizontal rollers 3 in the material flow detection system of the belt conveyor are eccentric rollers. structured as figure 2 As shown in (b), the arc transition between the eccentric block 301 and the circular support roller 302, the cross section of the eccentric block 301 is a crescent shape with a thick middle and thin sides, and the middle thickness of the crescent-shaped eccentric block 301 is the same as that of the circular support roller. The ratio of the diameter of the roller 302 is 2:100. A vibration sensor 5 is installed on the...

Embodiment 3

[0052] The basic structure and detection method of the belt conveyor material flow detection system in this embodiment are the same as those in Embodiment 1, the difference is that only one horizontal roller 3 is an eccentric roller in the belt conveyor material flow detection system in this embodiment, and the eccentric roller The roller is an elliptical roller 303, and the eccentricity of the cross-section of the elliptical roller 303 is 0.05. Through the material vibration signal generated by this elliptical roller 303, it is possible to detect whether there is material on the conveyor belt 1 in real time. The eccentricity can be determined according to the actual situation on site. The situation is slightly adjusted until the detected vibration signal is enough to be distinguished by the vibration sensor 5 when there is material and no material.
