DETAILED DESCRIPTION

[0038] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] Embodiment 1: Reference Figures 1-9 As shown: a quartz stone flotation belt type quantitative feeding conveyor, through the closed loop process of "visual perception-intelligent decision-making-execution adjustment", realizes the quantitative feeding and adaptive conveying of quartz stone (adjusting the angle of the roller according to the particle size), and finally stably conveying to the flotation system. The core goal is to solve the problem of fixed roller angle and poor applicability of traditional conveyor, and to improve the pre-treatment efficiency of flotation through quantitative control.

[0040] (I) Initial preparation and data collection.

[0041] Device initialization: before starting, the angle sensor 551 collects the initial inclination angle of the side roller 51, and feeds back to the data perception unit 6 of the electric control box 14 as the adjustment reference. The quartz stone raw material enters the vibrating feeder hopper 1 from the stock bin, waiting for conveying.

[0042] Particle size and distribution identification: the visual identification component 11 on the inner wall of the feeder hopper 1 takes pictures of quartz stone in real time, separates the material from the background through preprocessing (denoising, enhancement, segmentation), extracts the outline of a single quartz stone through edge detection, calculates the length of the circumscribed rectangle long axis (particle size value), and counts the distribution ratio according to the preset level, and synchronizes the data to the data perception unit 6.

[0043] (II) Intelligent decision-making generation (core function of electric control box 14).

[0044] Data comparison and judgment: the decision-making unit 7 of the electric control box 14 receives the information of the data perception unit 6 (particle size distribution, inclination angle of the side roller 51), and compares it through the preset parameters of the data analysis module 72 and the threshold setting module 71.

[0045] Instruction generation: if the current data (such as the actual particle size ratio, the angle of the side roller 51) exceeds the threshold value, the instruction generation module 73 issues adjustment instructions (such as "increase the angle of the side roller 51 to 20°" "reduce the feeding amount to 180 kg / h"); if it does not exceed the threshold value, it issues a maintenance state instruction.

[0046] (III) Execution adjustment (control of roller angle and feeding amount).

[0047] Side roller 51 angle adjustment (adapt to particle size), after receiving the instruction, angle adjustment module 82 of execution unit 8 controls motor 53 to start, motor 53 drives synchronous belt assembly to rotate, driving connecting piece 523 to rotate around hinged piece 522, and then changing the inclination angle of side roller 51 (the guide piece 55 at the other end of the side roller 51 slides along the guide frame 54 to ensure stability), during the adjustment process, the auxiliary wheel 593 rotates synchronously with the driving wheel two 533, and through the meshing of the toothed arm 594 and the guide rod 592, the guide plate 58 is driven to slide, so that the limiting piece 56 moves in linkage with the angle of the side roller 51, and the angle sensor 551 feedbacks the adjusted angle in real time until the target value is reached, and the motor 53 stops.

[0048] Feed amount adjustment (quantitative control): the feeding adjustment module 81 adjusts the vibration frequency of the lower hopper 1 or the opening degree of the lower feeding plate 13 according to the instruction: if the particle size is large (easy to block), reduce the vibration frequency to reduce the feed amount; if the particle size is small, increase the frequency to increase the feed amount; the visual recognition component 11 continuously monitors the feeding state, and if it is found that the material is stacked, it automatically triggers the speed reduction instruction to avoid blockage.

[0049] (Four) material conveying and abnormal handling.

[0050] Stable conveying: the driving assembly 4 drives the driving roller 34 to rotate, and the belt main body 3 runs under the support of the driving roller 34 and the tensioning roller 32 (to ensure that the belt is tensioned) to convey the quartz stone discharged from the lower hopper 1 to the end flotation machine.

[0051] Abnormal intervention: if the equipment fails (such as visual recognition failure, side roller 51 jam), the man-machine interaction unit 9 triggers an audible and light alarm, and the staff manually adjusts (such as adjusting the feed amount and the angle of the side roller 51 through the touch screen) through the manual correction module 83 to ensure uninterrupted conveying.

[0052] (Five) Summary.

[0053] The core advantage of the conveyor is "self-adaptive adjustment": through real-time sensing of the particle size of quartz stone by visual recognition, combined with intelligent decision-making of the electric control box 14, the angle of the supporting roller is adjusted (to avoid large particle size rolling and small particle size accumulation) and the feed amount is adjusted (to avoid blockage), and at the same time, the adjustment accuracy is guaranteed through mechanical structure and sensor, which greatly improves the stability and applicability of quartz stone conveying before flotation.
