Abstract

The invention is applicable to the technical field of coal screening and separation, and provides a multifunctional screening device for a coal mine. The multifunctional screening device comprises a device body, wherein a receiving system is arranged on the upper portion of the device body, a screening system and a control system are arranged in the device body, the screening system is connected with a driving system, and a pressure sensing system is arranged in the screening system; the pressure sensing system comprises movable plates located in grooves, each movable plate is located on the lower portion of a coal screening roller, second sliding grooves are formed in the two vertical side face walls of the inner side of each groove, second sliding blocks are arranged at the two ends of each movable plate, the second sliding blocks are movably connected with the interiors of the second sliding grooves, and a plurality of elastic elements are arranged on the lower portion of each movable plate; and a pressure sensor is arranged on the lower portions of the elastic elements of each movable plate. Therefore, the multifunctional screening device is simple in structure and reliable in design, overload work of the device can be prevented, the service life of the device is prolonged, coal ash can be effectively reduced, the screening efficiency is improved, the sieve length is shortened, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of coal screening and separation, in particular to a multifunctional screening device for coal mines. Background technique [0002] With the significant progress made in the independent innovation research of my country's intelligent coal mining technology and equipment, the device has achieved good application results in the coal mine production process, and the automation and unmanned production have been initially realized in many stages of coal production. At the same time, intelligent, high-yield and high-efficiency coal mines put forward higher requirements for coal mine processing systems, which require higher efficiency of coal mine processing systems, fewer related operators, and stronger informatization capabilities. Screening requires the use of screening devices. When the existing coal mine screening devices are in use, firstly, the screening process is prone to overload, which reduces the servic...
