Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The utility model provides a dust suppression device for intelligent information construction of coal mines, comprising: a motion platform 1, a spray assembly 4, a base 2, a swing assembly 3, a motion mechanism 31 and a swing member 32, etc. The motion platform 1 and the spray assembly 4, the motion platform 1 has a motion end that moves horizontally, the spray assembly 4 is arranged on the motion end, and the spray assembly 4 includes a water storage member 41 and a nozzle 42 that are connected to each other; the base 2 is fixedly connected to the lower part of the motion end, and the water storage member 41 is arranged on the base 2; the motion mechanism 31 is arranged at the lower part of the base 2, and the motion mechanism 31 has a horizontal rotating shaft 311; the nozzle 42 is arranged on the swing member 32, the swing member 32 is fixedly connected to the rotating shaft 311, and the rotating shaft 311 drives the swing member 32 to rotate; the spray assembly 4 also includes a corrugated hose 43, which is connected between the water storage member 41 and the nozzle 42.

[0038] Specifically, please refer to Figure 1-3 When in use, the motion platform 1 drives the base 2 to the spraying position, the spray assembly 4 and the swing assembly 3 are started, and the rotating shaft 311 reciprocates within a certain angle, driving the swing member 32 to swing, thereby driving the direction of the nozzle 42 to change. During this process, the corrugated hose 43 is pulled by the moving nozzle 42. Since the corrugated hose 43 has the functions of bending and stretching, it will not interfere with the movement of the swing member 32. At this time, the spray assembly 4 operates at the same time, and the water in the water storage member 41 is sent to the nozzle 42 to spray the water in the direction of the nozzle 42 to perform spray dust reduction treatment. Due to the swing of the swing member 32, the spray direction of the nozzle 42 is periodically changed, thereby increasing the spray range of the device, achieving beneficial effects, and improving the dust reduction effect.

[0039] Furthermore, in order to further improve the spraying range of the device, the motion mechanism 31 includes a plurality of swinging members 32, the motion mechanism 31 has a plurality of rotating shafts 311, there are a plurality of nozzles 42, there are a plurality of corrugated hoses 43, one swinging member 32 corresponds to one rotating shaft 311 and one corrugated hose 43, and at least one nozzle 42 is connected to one swinging member 32;

[0040] When multiple swinging members 32 are provided, the problem of synchronously supplying water to the nozzles 42 on the multiple swinging members 32 must be solved. Therefore, in particular, the base 2 has a liquid connecting chamber 21 inside, and the corrugated hose 43 water storage member 41 is connected to the liquid connecting chamber 21. The upper end of each corrugated hose 43 is connected to the bottom of the base 2 and is connected to the liquid connecting chamber 21, and the lower end of each corrugated hose 43 is connected to the nozzle 42 on the corresponding swinging member 32.

[0041] Furthermore, considering the balance between the spray range and the cost of the mechanism design, the motion mechanism 31 is configured to include two swing members 32, the motion mechanism 31 has two rotation shafts 311, and the corrugated hose 43 has two;

[0042] In the above arrangement, the motion mechanism needs to have a setting that can well realize the synchronous rotation of the two rotating shafts 311, so the motion mechanism 31 also includes: a connecting member 312, the connecting member 312 is fixedly connected to the bottom of the base 2, and the rotating shaft 311 is rotatably connected to the connecting member 312; a linear driving member, the linear driving member is arranged on the connecting member 312, the linear driving member includes a linear motion part 313, the linear motion part 313 performs reciprocating linear motion on a horizontal plane, the movement direction of the linear motion part 313 is a first direction, the two swinging members 32 are respectively located on both sides of the linear motion part 313 in the first direction, and the two rotating shafts 311 are respectively located on both sides of the linear motion part 313 in the first direction; two racks 314, both are fixedly connected to the linear motion part 313, and the two racks 314 are respectively located on both sides of the linear motion part 313 in the first direction; a gear 315, the gear 315 is fixedly sleeved on the rotating shaft 311, and the gear 315 is meshed with the rack 314.

[0043] Through the above arrangement, the two rotating shafts 311 can be synchronously rotated by only one linear drive member, achieving a method of achieving both efficiency and cost. In this embodiment, the linear drive member uses a motor as the core driving device. In other embodiments, a cylinder or hydraulic power can also be used to drive the linear motion part.

[0044] Furthermore, the stable operation of the above-mentioned motion mechanism 31 depends on the stable and smooth linear motion of the linear motion part, so the motion mechanism 31 also includes: a guide rod 316, the guide rod 316 is fixedly connected to the connecting member 312, and the length direction of the guide rod 316 is parallel to the first direction, and a sliding hole is provided on the linear motion part 313, and the guide rod 316 is slidably connected in the sliding hole.

The position of the integrated hood 53 makes the air it extracts come from the spraying area created by the spray assembly, so as to better reflect the value of the device in improving the spraying effect.

[0048] Furthermore, considering that the optimal position of the integrated cover 53 should be between the two swinging members 32, in order to best exert the beneficial effect of lifting the spraying area, it is also necessary to adaptively adjust the features related to the integrated cover 53.

The above arrangement enables the integrated cover 53 to be well matched with the base 2.

[0049] Furthermore, considering that the integrated cover 53 is a component located at the bottom center of the base 2, its function can also take into account the functions of some connecting components. Therefore, the connecting piece 312 is fixedly connected to the outer surface of the dust collecting cover 53, or in some embodiments, the outer wall of the integrated cover 53 can also be directly used as the connecting piece 312.

[0050] Furthermore, since more driving components and nozzles 42 are used, the device needs to be operated more efficiently and with lower energy consumption, and needs to be assisted by an intelligent / automated control system.

[0051] Furthermore, the suction assembly 5 further comprises: a filter screen 54, and the filter screen 54 is arranged between the air pump 51 and the suction pipe 52, so as to further exert the beneficial effect of improving the spraying effect.
