Description

Gangue conveying nutrient soil processing equipment based on industrial vision Technical Field The invention relates to the technical field of conveying equipment, in particular to coal gangue conveying nutrient soil processing equipment based on industrial vision. Background The utilization of coal gangue as solid waste generated in the coal exploitation and washing process has become an important research direction in the field of energy conservation and environmental protection. The coal gangue is processed into the nutrient soil through the procedures of crushing, screening, improvement and the like, which is one of effective ways for realizing the resource utilization of the coal gangue, and the conveying equipment is used as a key link in the process of processing the coal gangue into the nutrient soil, and the operation stability and the conveying accuracy of the conveying equipment directly influence the efficiency of the subsequent processing procedures and the quality of the finished product of the nutrient soil. The existing gangue conveying nutrient soil processing equipment mostly adopts a traditional conveying mode of a conveying belt, and mainly comprises a frame, the conveying belt, a feeding hopper, a driving motor and other basic components. However, in the practical application process, the conventional conveying equipment has a plurality of technical pain points, and the requirements of high-efficiency and accurate processing are difficult to meet: Firstly, the accuracy of the feed quantity regulation is insufficient. The feeder hopper of the existing equipment adopts a single valve plate or a manual adjustment mode to control the blanking amount, and the self-adaptive adjustment can not be carried out according to the actual stacking height of the materials on the conveying belt. When the discharging amount of the gangue raw materials is suddenly increased, excessive accumulation of the materials on the conveying belt is easily caused, the clamping and deviation of the conveying belt and even the overload damage of equipment are caused, and when the discharging amount is too small, the conveying belt idles, the conveying efficiency is reduced, and meanwhile, the energy loss is increased. Secondly, the suitability of the conveying speed and the feeding amount is poor. The driving motor of the existing equipment mostly adopts fixed rotation speed to run, and the speed of the conveyer belt can not be dynamically adjusted according to the change of the feeding quantity. When the feeding amount is not matched with the conveying speed, the problem of material accumulation or idle running is aggravated, the uneven distribution of materials on the conveying belt is caused, the stability of the processing procedures such as subsequent crushing, screening and the like is affected, and the processing quality of the nutrient soil is further reduced. In addition, the mode of manual regulation and control motor rotational speed response is lagged, and needs to consume a large amount of human cost, is difficult to adapt to the large-scale production demand. Thirdly, the problem of material conveying deviation is prominent. In the conveying process of gangue raw materials, the gangue raw materials are influenced by factors such as feeding position deviation and conveyor belt vibration, and are easy to deviate to two sides of the conveyor belt, so that material scattering loss is caused, meanwhile, the deviated materials can aggravate the abrasion of the edge of the conveyor belt, and the service life of equipment is shortened. Although the existing equipment is partially provided with a side pushing guide structure, a baffle plate at a fixed position or a manually-adjusted push plate cannot adaptively adjust the side pushing amplitude according to the running speed of the conveying belt. When the conveyer belt rotational speed changes, fixed side pushes away the problem that the dynamics of pushing away is insufficient or excessively extrudees the material easily appears, or can not effectively correct the material skew, or can lead to gangue granule breakage, influences the improvement effect of follow-up nutrient soil.

The scheme for solving the technical problems is as follows: the invention provides industrial vision-based coal gangue conveying nutrient soil processing equipment, which comprises: A frame; the conveying belt is arranged on the frame in a transmission way through a supporting roller and an adjusting roller; The feeding hopper is erected above the feeding end of the frame through a bracket; the visual camera is arranged on the bracket through a supporting rod and is positioned above the central line of the frame; A control assembly mounted inside the bracket; The valve
