Problems solved by technology

[0004] Aiming at the problem of dust reduction and dust prevention of dust, it is an essential and important way to study dust reduction technology by carrying out simulation experiments of cutting coal and rock crushing dust production. Considering the research and development of dust suppression technology, it will match the actual situation in the later stage. Therefore, there is an urgent need for a crushing and dust production simulation experimental device for cutting coal and rock mass by roadheaders to solve the above problems

Abstract

The invention discloses a breaking dust generation simulation experiment device for coal and rock mass cutting of a heading machine, which comprises an experiment table, supporting legs are fixedly connected to four corners of the bottom end of the experiment table, a coal and rock mass simulation mechanism and a heading machine simulation mechanism are arranged at the top end of the experiment table, and the coal and rock mass simulation mechanism and the heading machine simulation mechanism are correspondingly arranged. A glass cover is hinged to the top end of the experiment table, a ventilation opening is formed in the glass cover, a dust collecting and analyzing mechanism is arranged at the top end of the experiment table and corresponds to the glass cover, and a control mechanism is arranged on the side wall of the experiment table. The coal and rock mass simulation mechanism, the heading machine simulation mechanism, the ventilation opening and the dust collection and analysis mechanism are all electrically connected with the control mechanism. According to the device, the breaking dust production simulation experiment of coal and rock mass cutting of the heading machine is achieved, the device is convenient to adjust, measurement data are accurate, meanwhile, the service life of the device is prolonged, and the experiment cost is saved.

Description

technical field [0001] The invention relates to the technical field of simulation experiment devices, in particular to a crushing and dust production simulation experiment device for cutting coal and rock masses by roadheaders. Background technique [0002] The roadheader is a machine used to excavate roadways on the flat ground. It is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a transfer mechanism. It has the advantages of safety, high efficiency and good quality of lane formation. [0003] my country is a large coal-producing country with numerous coal mines of various sizes. With the rising prices of energy such as oil and natural gas, coal has become a popular energy source in China, and the demand for it will be huge in the future, which will stimulate the rapid development of the coal mining industry. As an advanced and efficient large-scale mechanized equipment, roadheaders have been widely promoted in roadway and tunnel e...
