[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3, the utility model provides a technical solution: a dust reduction device for preventing dust in a mine ore yard, including an installation frame 1. The two ends of the installation frame 1 are respectively rotatably provided with a front cross tube 2 and a rear cross tube 3. The side of the front cross tube 2 is evenly provided with atomizing nozzles one 21 that spray water mist downward and toward the rear cross tube 3. The side of the rear cross tube 3 is evenly provided with atomizing nozzles two 31 that spray water mist downward. At both ends of the side of the rear cross tube 3, there are atomizing nozzles three 32 that spray water mist toward the lower side of the front cross tube 2. The ore unloading truck pours in from the lower side of the front cross tube 2. While unloading the ore, control the atomizing nozzles one 21, atomizing nozzles two 31, and atomizing nozzles three 32 to spray water mist simultaneously to form a space composed of water mist. When unloading the ore, the water mist around and above the ore truck blocks the dust and makes the dust settle.

[0019] At the part of the middle of the installation frame 1 that is biased toward the rear cross tube 3, there is a negative pressure tube 4. The lower side of the negative pressure tube 4 is provided with evenly distributed suction nozzles 41. Connect the external negative pressure device to the negative pressure tube. When unloading the ore, the suction nozzles 41 are closer to the ore. Part of the dust generated during ore unloading is extracted by the negative pressure tube, and the other part settles under the action of the water mist. On one side of the installation frame 1, there is a driving member that respectively drives the front cross tube 2 and the rear cross tube 3 to rotate, which can drive the front cross tube 2 and the rear cross tube 3 to rotate, so as to adjust the angles of the atomizing nozzles on the front cross tube 2 and the rear cross tube 3.

[0020] Further, the driving member includes two electric push rods 6 symmetrically arranged at the upper end of the side of the installation frame 1. The fixed end of the electric push rod 6 is provided with a toothed plate 61. The end parts of the front cross tube 2 and the rear cross tube 3 are respectively provided with gears 5 that mesh with the corresponding toothed plates 61. The electric push rod 6 drives the toothed plate 61 to move. During the movement of the toothed plate 61, it drives the gears 5 to rotate. The two gears 5 respectively drive the front cross tube 2 and the rear cross tube 3 to rotate, so as to adjust the angles of the atomizing nozzles on the front cross tube 2 and the rear cross tube 3, and then spray water mist through the atomizing nozzles for sedimentation operation.

[0021] Further, a guide plate 62 for supporting and guiding the toothed plate 61 is provided on the side of the installation frame 1.

[0022] Further, the bottom of the installation frame 1 is provided with track wheels, and the track wheels are slidably arranged on the track, which is convenient for the movement of the entire dust reduction device.

[0023] Further, a traction ring is provided at the lower end of the side of the installation frame 1 corresponding to the front cross tube 2. Connect the traction steel wire rope to the traction ring, and the entire dust reduction device can be driven to move by an external winch.

[0024] The electric push rod 6 used in the utility model is a common electrical component in the prior art, and its working mode and circuit structure are both well-known technologies, which will not be elaborated here. The electric push rod 6 is electrically connected to an external switch.

[0025] When in use:

[0026] The ore unloading truck is poured from the lower side of the front horizontal pipe 2. While unloading the ore, the atomizing nozzles I 21, the atomizing nozzles II 31, and the atomizing nozzles III 32 are controlled to spray water mist simultaneously to form a space composed of water mist.

[0027] When unloading the ore, the water mist around and above the ore truck blocks the dust and makes the dust settle.

[0028] In addition, an external negative pressure device is connected to the negative pressure pipe. When unloading the ore, the suction nozzle 41 is closer to the ore, and part of the dust generated during unloading is extracted by the negative pressure pipe, and the other part settles under the action of the water mist.

[0029] During the stacking of the ore, due to weather reasons, the dust on the ore will be blown up, causing dust. At this time, when the dust detection device on the dust reduction device detects dust, it sprays water mist for dust reduction. The specific operation steps are as follows:

[0030] The electric push rod 6 is controlled to work through an external switch. The electric push rod 6 drives the toothed plate 61 to move. During the movement of the toothed plate 61, the gear 5 is driven to rotate. The two gears 5 respectively drive the front horizontal pipe 2 and the rear horizontal pipe 3 to rotate, so as to adjust the angles of the atomizing nozzles on the front horizontal pipe 2 and the rear horizontal pipe 3, and then spray water mist through the atomizing nozzles for the settling operation.

[0031] The utility model can form a space composed of water mist and perform ore loading and unloading operations in this space; it can also extract the dust while settling the dust, thereby improving the treatment effect of the dust, having a good dust reduction effect and being convenient to use.
