Mining mechanical automatic spraying device

Abstract

Disclosed is a mining mechanical automatic spraying device. The mining mechanical automatic spraying device comprises a base, a rotary disc supported on the base in a rotating mode, a water tank fixedto the rotary disc and rotating along with the rotary disc, a control device fixed to the base and connected with the water tank in a matched mode, and a trigger device matched with the rotary disc.The control device comprises a water inlet pipe fixed to the base, a control valve connected with one end of the water inlet pipe, a connecting pipe connected with the control valve, an adjusting valve connected with the upper end of the connecting pipe and a water outlet pipe arranged in the middle of the connecting pipe and extending backwards, and a control valve rod is arranged on the controlvalve. The control valve rod extends towards one side of the water tank and is movably connected with the water tank; a weeping pipe matched with the water tank is arranged on the side, facing the water tank, of the upper portion of the adjusting valve; a lower locking rod connected with the triggering device is formed upwards on the rotary disc; and a balancing weight is fixed to the position, obliquely upwards on the rear side of the lower locking rod, of the rotary disc. The spraying duration can be effectively controlled, and the reset action is more stable and reliable, and the overall size is small.

Description

technical field [0001] The invention belongs to the technical field of mine dust suppression equipment, and in particular relates to a mine mechanical automatic spraying device. Background technique [0002] Coal mines are the main natural resources of our country. Rational use and exploitation of coal mines is an important part of promoting my country's economic development. However, there are great safety risks in the mining process of coal mines. A slight negligence may cause an explosion to cause the mine to collapse. Explosions caused by excessive dust concentration are relatively common accidents. Among them, blasting is a commonly used coal mining method. It has high mining efficiency and large output, but the amount of dust generated is relatively large. If the dust cannot be suppressed in time, it will be very difficult. There is a risk of explosion. At present, solenoid valves or sensors are often used to control spraying devices in mines to achieve the purpose of...

AI Technical Summary

Problems solved by technology

Both of them can be stably triggered by impact force and carry out spray and dust reduction during blasting operation, but there are still the following deficiencies: first, the structure of both is relatively loose, resulting in a large volume, which is not conducive to logistics transportation and installation; second , the former uses a lever-type heavy hammer lifting device to reset, which involves many and cumbersome steps in the actual operation process, and some even still need to use the motor to realize the reset operation, and the work stability is poor, while the latter does not consider reset at all. and spraying time, both of which cannot meet the needs of blasting operations
