Jigging machine self-adaptive buoy device based on machine vision and discharging method

Abstract

The invention discloses a jigging machine self-adaptive buoy device based on machine vision. The jigging machine self-adaptive buoy device based on machine vision comprises a machine vision instrument, an ash measuring instrument, a jigging machine discharging device, a control processor, a self-adaptive buoy counterweight device and a discharging impeller; the machine vision instrument and the ash measuring instrument are arranged in front of a feeding port of the jigging machine and are connected with the control processor respectively; the jigging machine discharging device is in charge ofsorting and discharging work of coal; the self-adaptive buoy counterweight device is connected with the control processor; the discharging impeller is arranged below a discharging port jigging machinesieve plate; and the control processor controls the rotating speed of the discharging impeller according to a heavy product bed thickness signal acquired by a counterweighted buoy to achieve a good sorting effect. The jigging machine self-adaptive buoy device based on machine vision automatically changes the counterweight of the buoy device by detecting parameters such as variety and density of the coal by the machine vision instrument and the ash measuring instrument so as to detect the thickness of the true bed adapting to different materials, is accurate and reliable, and saves manpower resource.

Description

Technical field [0001] The invention relates to the technical field of coal preparation equipment, in particular to a jigger adaptive buoy device and a discharge method based on machine vision. Background technique [0002] Jigging coal preparation is to separate the particles in the pulsating water flow that reciprocates up and down according to the different properties of the particles themselves. In actual production, the jig machine sends the raw materials that need to be separated to the sieve plate and spreads them into a compact layer. This compact layer is called the bed. During the production process, the raw materials are fed into the machine, and the jig machine provides a reciprocating pulsating water flow. Under its movement, the raw materials are slowly separated; by repeated impacts of the pulsating water flow, the bed layer begins to loosen and gradually begins to separate. , Into the water; different substances in these raw materials will show different trajecto...

Problems solved by technology

[0004] However, in jigging separation, in order to better distinguish the boundary line between each layer and gangue, it is necessary to place a buoy to distinguish the interface, to distinguish the interface between the coal seam and gangue, but before each coal feeding, It is necessary to manually re-calibrate the buoys according to the different parameters such as the type and density of the incoming coal, in order to achieve a better separation effect, but each time the buoy calibration must be performed manually, which is time-consuming and labor-intensive, and the manual calibration is not accurate.
