Coal mine heading machine with high safety performance

Abstract

The invention discloses a coal mine heading machine with high safety performance, and relates to the technical field of coal mine heading machines. The machine aims to improve the cooling reliability.The machine particularly comprises a machine body and a tunneling head, wherein a first adjusting base is fixed to the outer wall of one side of the machine body through screws, a first mounting frame is rotatably connected to the outer wall of one side of the first adjusting base, a tunneling motor is fixed to the first mounting frame through screws, an output end of the tunneling motor is rotatably connected with a rotating sliding seat through a coupling, and a rotating sliding rod is slidably connected into the rotating sliding seat through a strip-shaped sliding block; and the tunnelinghead is fixed to the outer wall of one end of the rotating sliding rod through bolts, and a telescopic adjusting cylinder is fixed to the first mounting frame through screws. By arranging a main sprayhead, an auxiliary spray head and other structures, the tunneling head and the surrounding environment can be cooled in a cooling liquid spraying mode, the dust falling effect is achieved, and in addition, by arranging a temperature sensor, automatic control over the auxiliary spray head and the main spray head can be achieved based on the temperature fed back by the temperature sensor.

Description

technical field [0001] The invention relates to the technical field of coal mine roadheaders, in particular to a coal mine roadheader with high safety performance. Background technique [0002] The roadheader is a kind of equipment commonly used in coal mining operations in coal mines. Although the general roadheader has the ability to move and adjust the tunneling attitude to meet the needs of the operation, due to the particularity of the coal mining operation, it is necessary to eliminate potential safety hazards as much as possible. The most important thing in the field, the environmental temperature problem has always been the focus of attention in coal mining operations. Since the tunneling head is constantly rubbing against the coal seam during work, a large amount of heat and dust are generated. Usually, the tunneling head is sprayed with coolant.

[0002] Roadheader is a kind of equipment commonly used in coal mining operations in coal mines. Although general roadheaders have the ability to move and adjust the tunneling attitude to meet the needs of the operation, due to the particularity of coal mining operations, it is a must to eliminate potential safety hazards as much as possible. The most important thing in the field, the environmental temperature problem has always been the focus of attention in coal mining operations. Since the tunneling head is constantly rubbing against the coal seam during work, a large amount of heat and dust are generated, and the cooling liquid is usually sprayed on the tunneling head. cooling and dust reduction, and the timing of spraying coolant is difficult to grasp, so that the cooling cannot be achieved reliably and in a timely manner

The spray dust suppression device in the above-mentioned patent has the following disadvantages: the timing of spraying is not easy to grasp, so that the cooling and dust reduction cannot be realized reliably and in time.
