TECHNICAL FIELD
[0001] The present application relates to the field of transportation measurement technology, in particular to a mine belt conveyor capable of intelligent operation. BACKGROUND
[0002] After processing, mineral products are generally transported to storage by belt conveyor. The process requires accurate measurement of product weight, but due to space constraints, electronic belt scales cannot be installed on the belt conveyor. At this time, a space-saving measurement device is needed to complete the measurement task. However, space is limited, and the belt conveyor needs to measure powdery materials, but there is not enough space to install an electronic belt scale, making it impossible to measure copper and gold products.

[0004] Although the above scheme reduces space occupation and can complete measurement, the weighing device is arranged at the end of the belt conveyor and the material is unloaded after reaching the specified weight, which requires the belt conveyor to stop. This is because the belt conveyor cannot drive new mineral materials to fall during unloading. Only after unloading is completed, the belt conveyor will start again, which greatly affects the efficiency of the belt conveyor during transmission, and also causes the accumulation of mineral materials at the loading end of the belt conveyor.

[0062] The third cavity can be filled with water or oil. The triggering method of the support device 223 in the second embodiment of the collecting device 2 differs from that in the first embodiment. As ore is continuously fed into the second weighing shell 214, the second weighing shell 214 is inserted into the second annular slot via the second annular insert plate 2235. The liquid in the second cavity then flows into the storage shell 2237 through the connecting pipe 2236.

This causes the sliding block 2238 in the storage shell 2237 to rise and trigger the triggering device. The triggering device includes a trigger button 2239, which is located on the top of the storage shell 2237. When the triggering device is triggered by the sliding block 2238, it indicates that the weight of the ore in the second weighing shell 214 has reached the pressure pre-set value.

The abutment plate 224 can slide along the axis of the second shell 215. A linear actuator 225 is vertically provided at the bottom of the abutment plate 224. When the linear actuator 225 drives the abutment plate 224 to rise, the abutment plate 224 lifts the bottom of the extension rod 222. When the output end of the linear actuator 225 is not extended, even when the second weighing shell 214 is lowered to the lowest point, the extension rod 222 on the second weighing shell 214 will not contact the abutment plate 224. After unloading is completed, the sliding block 2238 pushes the liquid from the third cavity back into the second cavity, so that the second cavity drives the second weighing shell 214 to rise again.

[0073] (I)
[0074] wherein, is the actual degree of completion of the belt conveyor when conveying the ore, is the detection value of the speed sensor one, is the detection value of the speed sensor two, is the detection value of the rotation speed sensor, is the radius of the extension rod 222, is 3.14, is the opening area of the collecting pipe 4, is the cross-sectional area of the guide pipe 31, L is the distance of the ore conveyed into the collecting device 2 along the collecting pipe 4, the main pipe 32 and the guide pipe 31, is the included angle between the two groups of guide pipes 31, is the included angle between the guide pipe 31 and the weighing device 21, sin is the sine, cos is the cosine, and ln is the natural logarithm.
[0075] Step 2: The working state index of the belt conveyor is calculated based on Step 1 and Formula Two.
[0076] (II)
[0077] wherein, is the working state index of the belt conveyor, is the loss coefficient of the conveyor body 1, the value is greater than 0 and less than 1, which can be related to the used time length of the conveying belt of the conveyor body 1, the influence of the use environment on the conveying belt, the longer the used time length and the worse the environment, the greater the value, and K is the average value of the precision of the speed sensor one, the speed sensor two and the rotation speed sensor.
[0078] Step 3: The controller compares the working state index of the working state index of the belt conveyor with the preset working state index, and when the working state index of the belt conveyor is less than the preset working state index, the controller controls the alarm to issue an alarm prompt.
[0079] The working principle and beneficial effects of the above technical solutions are:
[0080] Among them, Indicates the influence degree of the initial speed of transporting the ore through the belt conveyor in the process of entering the collecting device 2 through the collecting pipe 4, the main pipe 32 and the guide pipe 31 on the ore conveying process through the conveying drop angle, and then according to The size limitation of the collecting pipe 4 and the guide pipe 31 itself is corrected to the influence of the data in the conveying process, so as to obtain the actual completion degree of the belt conveyor conveying the ore;
[0081] Indicates the working state index of the belt conveyor obtained by the influence degree of the actual conveyor body 1 and the plurality of sensor precisions on the actual completion degree of the belt conveyor conveying the ore under the influence of the conveying drop angle on the actual completion degree of the belt conveyor conveying the ore. In the process of long-time conveying of the ore by the belt conveyor, the speed sensor one, the speed sensor two and the rotational speed sensor detect the key state of each component in the conveying process of the ore, the controller obtains the actual completion degree of the belt conveyor conveying the ore by using formula one and calculates the working state index of the belt conveyor by using formula two. When the working state index of the belt conveyor is less than the preset working state index (0.9), the controller controls the alarm to issue an alarm prompt, so as to remind the worker to overhaul the belt conveyor, and improve the safety and reliability of the device.
