Dense medium shallow slot dredging device based on machine vision and control method

Abstract

The invention provides a dense medium shallow slot dredging device based on machine vision and a control method. The dense medium shallow slot dredging device comprises a dense medium shallow slot, a visual detection assembly, a central processing unit and an overflow weir dredging device. The dense medium shallow slot is provided with an overflow weir, and the visual detection assembly is installed above the overflow weir; the overflow weir dredging device is installed in the dense medium shallow groove and located above the overflow weir, the visual detection assembly and the overflow weir dredging device are connected with a central processing unit, the visual detection assembly comprises an industrial camera and an LED light source, and the overflow weir dredging device comprises a support, a horizontal sliding rail, a rotating motor, a ball screw, a sliding block and a manipulator. The coal briquettes are recognized in a machine vision mode, the overflow weir is dredged through automatic mechanical equipment, the burden of field workers is relieved, accuracy is high, dredging operation is timely, heavy-medium shallow groove production abnormity can be avoided, and the sorting work efficiency can be improved.

Description

Technical field [0001] The present invention relates to the technical findings of the coal mining equipment, and more particularly to a machine-based annotation shallow dredging device and a manipulation method. Background technique [0002] Re-shallow slot sorting machine is sorted by the application of Aquiimide's law in gravity field. When the suspension enters the interior of the sorting trough, the liquid is divided into an upflow and horizontal flow. The rising flowers flowing through the hole enters the tank, so that the suspension is evenly distributed in the slot; the horizontal flow is to maintain the density of the suspension in the groove, which contributes to the transport of superior coal. Under the action of the horizontal flow, low density substances in some suspensions can be discharged along the stocking exit to ensure the density and quality of the coal. [0003] The weight of the shallow slot sorting machine is composed of a tank body, a diamond scraper and a ...

Problems solved by technology

[0004] However, when the dense medium is separated in the shallow tank, the lighter coal flows out through the overflow weir, and the sorted coal will be mixed with large coal pieces from time to time. These large pieces of coal will be blocked by the overflow weir because they sink too deep into the water surface. Cause a certain sorting congestion, affect the sorting effect, and even cause equipment damage in severe cases

At present, it is generally used to manually observe the outlet of the overflow weir. When a large piece of coal is stuck, the staff uses iron tools to move the coal to pass through the overflow weir to achieve the purpose of dredging, but this method is not only labor-intensive Material resources and costs are high, and the working environment of workers is poor, accompanied by certain dangers
