Description

TECHNICAL FIELD

[0001] The utility model belongs to the mining dust fall equipment technical field, concretely relates to a kind of wind water spray dust fall device of mining heading machine. BACKGROUND

[0002] Heading machine is the mechanical essential for coal mining, and it can crush rock mass or coal seam by applying axial pressure and rotary force, which will produce a large amount of dust during the working process of heading machine. The dust will not only affect the health of miners and reduce the visibility of operation, but also cause explosion when the concentration reaches a dangerous level. Currently, atomized water cannons are usually arranged around the heading machine to spray dust at the heading position. However, the position of the heading machine will move during the work, and the atomized water cannons cannot track the working position in real time to reduce dust, so manual adjustment of the position of the atomized water cannons is often required, which is very wasteful of manpower and resources. In addition, during the work of the heading machine, the rotation of the cutter will cause the dust to fly in all directions. The traditional water cannons can only reduce dust in a certain direction, but cannot completely cover the position around the cutter, so the dust reduction effect has been criticized by the industry, and therefore there is an urgent need for a device that can move with the heading machine and reduce dust in all directions around the cutter.

This water mist dust suppression device needs to be operated manually to accurately spray dust at the heading position, so it cannot meet the needs of reducing labor cost and work intensity and improving dust reduction effect.

[0004] In view of the above, it is necessary to design a wind water spray dust fall device for mining heading machine, which is simple in structure, low in cost, can be installed on the heading machine to move with the heading machine, and can cover the water mist around the cutter of the heading machine. For this purpose, the applicant has made a useful design, and the technical solution to be introduced below is produced in this background. UTILITY MODEL CONTENTS
