The outer part of the first rotating shaft 601 is rotatably connected with a rotating sleeve 602. The top end of the rotating sleeve 602 is fixedly connected with a connecting block 603. The connecting block 603 is rotatably connected with a second rotating shaft 604. The second rotating shaft 604 is fixedly connected with a fixing block 605. The top end of the fixing block 605 is fixedly connected with a fixing rod 5. A plurality of atomizing nozzles 4 are installed on the fixing rod 5. The water inlet of the atomizing nozzle 4 is fixedly connected with a water pipe 3. The ends of the plurality of water pipes 3 are fixedly connected with the same pressurized water tank 2. The bottom end of the pressurized water tank 2 is fixedly connected with a mounting bracket 7. The first rotating shaft 601 and the second rotating shaft 604 are perpendicular to each other with respect to the middle part of the mounting disc 1. The top end of the connecting block 603 is in an annular structure. The fixing block 605 is in a "U" shape structure. A limiting structure 8 is installed on the rotating sleeve 602; by installing the rotating structure 6 on the mounting disc 1, the spraying direction and spraying angle of the atomizing nozzle 4 can be flexibly adjusted through the rotating structure 6, so that the dust removal device is more flexible to use and the dust removal effect is better.

[0022] As a technical optimization solution of the utility model, a groove 606 is provided on the connecting block 603, a protrusion 607 is slidably connected in the groove 606, a knob 608 is rotatably connected to the protrusion 607, the knob 608 is threadedly connected to the fixed block 605, the groove 606 is annular in structure as a whole, and the cross-section of the groove 606 is a "T"-shaped structure; the protrusion 607 presses against the inner wall of the connecting block 603, so that the connecting block 603 can no longer rotate, thereby increasing the flexibility of the angle adjustment of the atomizing nozzle 4.

[0023] As a technical optimization scheme of the utility model, the limiting structure 8 includes a limiting groove 801, and a plurality of limiting grooves 801 are arranged in a circular array on the first rotating shaft 601, wherein a limiting rod 802 is engaged in one of the limiting grooves 801, and the limiting rod 802 is slidably connected to the rotating sleeve 602, and a handle 803 is fixedly connected to the outside of the rotating sleeve 602, and the end of the limiting rod 802 away from the first rotating shaft 601 is slidably connected to the handle 803, and a spring 804 is fixedly connected between the limiting rod 802 and the handle 803, so as to facilitate the limiting of the rotating sleeve 602 and facilitate the angle adjustment of the rotating sleeve 602.

[0024] As a technical optimization solution of the utility model, a sliding groove 806 is provided on the handle 803, and a pull rod 805 is slidably connected in the sliding groove 806. The pull rod 805 is fixedly connected to the limiting rod 802, the limiting rod 802 and the pull rod 805 are perpendicular to each other, and the handle 803 and the rotating sleeve 602 are perpendicular to each other. The setting of the sliding groove 806 facilitates the operation of the pull rod 805.

[0025] When the utility model is in use, first fix the mounting bracket 7 on the fuselage of the roadheader to fix the pressurized water tank 2, and then install the mounting disc 1 on the cutting part of the roadheader through bolts, so as to fix the atomizing nozzle 4, facilitating the dust suppression device to spray and suppress dust in the area with serious dust. Then hold the handle 803 and pull the pull rod 805 at the same time. The pull rod 805 drives the limit rod 802 to slide out of the limit groove 801, thus releasing the fixation of the rotating sleeve 602. The handle 803 drives the rotating sleeve 602 to rotate, so as to quickly and flexibly adjust the horizontal angle of the atomizing nozzle 4, and then make the atomizing nozzle 4 aim at the area with serious dust. During the sliding process of the limit rod 802, the spring 804 is pushed to contract. When the rotating sleeve 602 is adjusted to the right direction, release the handle 803 and the pull rod 805. The spring 804 resets and drives the limit rod 802 to engage into the corresponding limit groove 801 at the same time, so that the rotating sleeve 602 stops rotating, and then the atomizing nozzle 4 is fixed, increasing the stability of the atomizing nozzle 4; When it is necessary to adjust the vertical angle of the atomizing nozzle 4, rotate the knob 608. The knob 608 drives the convex block 607 to slide until the convex block 607 no longer abuts against the inner wall of the connecting block 603. Then push the fixing rod 5, and the fixing rod 5 drives the fixing block 605 and the second rotating shaft 604 to rotate, so as to adjust the vertical angle of the atomizing nozzle 4. When the vertical angle of the atomizing nozzle 4 is adjusted, rotate the knob 608. The knob 608 drives the convex block 607 to press against the inner wall of the connecting block 603, so that the fixing block 605 can no longer rotate, and then the flexibility of the angle adjustment of the atomizing nozzle 4 is increased, and the dust suppression effect of the dust suppression device is better.
