Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 Shown is a structural block diagram of an automatic control system for a continuous mining feeding crusher of the present invention, including:
[0024] Main control unit 1, distance alarm unit 2, conveyor 3, crusher 4;
[0025] The output end of the distance alarm unit 2 is connected to the input end of the main control unit 1, and the output end of the main control unit 1 is connected to the conveyor 3 and the crusher 4 respectively;
[0026] The distance alarm unit 2 detects the distance between the vehicle transporting materials to the conveyor 3 and the crusher 4 and the crusher 4, and when the distance is less than or equal to a preset distance threshold, the main control unit 1 sending the distance alarm signal;
[0027] The main control unit 1 receives the distance alarm signal from the distance alar...

The invention discloses an automatic control system for a continuous collection and feeding crusher and a control method of the automatic control system. The control system comprises a main control unit, a distance alarming unit, a conveyor and a crusher, wherein the distance alarming unit is used for detecting the distance between the crusher and a vehicle for conveying materials to the conveyor and the crusher; when the value of the distance is less than or equal to a pre-set distance threshold value, the distance alarming unit sends a distance alarming signal to the main control unit; the main control unit receives the distance alarming signal from the distance alarming unit to sequentially start the conveyor and the crusher; and when the control unit exceeds a pre-set conveying and crushing shutdown time threshold value and does not obtain the distance alarming signal from the distance alarming unit, the conveyor and the crusher are sequentially stopped. In the whole process, manual intervention is not needed, resource wastes are reduced and the noise disturbance is avoided.
Description
technical field [0001] The invention relates to the technical field related to continuous mining feed crushers, in particular to an automatic control system and a control method for continuous mining feed crushers. Background technique [0002] At present, the overall control level of the mine feed crusher still stays at the local manual local control. Generally, the operator uses the operation button and hydraulic handle on site to control the start and stop of the power supply device, and the transportation and walking of the feed crusher. The feeding crusher used in the continuous mining excavation working face is an intermittent working system. After the shuttle car unloads, the feeding crusher completes the tasks of receiving, crushing and transporting. After the task is completed, the shuttle car has not yet completed the next transportation , At this time, the feeding crusher is idle waiting, which not only wastes energy, but also produces high-decibel noise, which g...
