DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in 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.
[0019] like Figures 1 to 5 As shown, the utility model provides a dust purification device for mining production, including a box body 1, a feed hopper 2 for introducing dust is fixedly connected to the top of the box body 1, a sieve plate 3 is hinged on the top of the inner side of the box body 1, one end of the box body 1 is rotatably connected to a hollow shaft 4 that penetrates the side wall of the box body 1, one end of the hollow shaft 4 is fixedly connected to a cam 5, the cam 5 can cooperate with the rotation of the hollow shaft 4 to drive the sieve plate 3 to rotate upward intermittently, one end of the box body 1 is fixedly connected to a discharge hopper 8, the inlet end of the discharge hopper 8 is connected to one end of the sieve plate 3, the other end of the hollow shaft 4 is provided with a driving mechanism 6 that drives the hollow shaft 4 to rotate, and a buffer mechanism 7 for buffering the sieve plate 3 is provided below the sieve plate 3, the buffer mechanism 7 includes a support plate 71, and the support plate 71 is fixedly connected to the box body 1. The cam 73 is pressed against the locking cam 74 at the bottom of the two locking cams 74, and the cam 73, when in contact with the locking cam 74, can prevent the cam 73 from being damaged.
[0020] Dust can be screened through the sieve plate 3. Large dust particles will be screened out by the sieve plate 3, and small dust will pass through the sieve holes of the sieve plate 3 and enter the bottom end of the inner side of the box body 1. At the same time, the driving mechanism 6 drives the hollow shaft 4 to rotate, which causes the cam 5 to rotate. When the cam 5 contacts the bottom wall of the sieve plate 3, the sieve plate 3 will be lifted up by the cam 5 and rotate upward. When the cam 5 is separated from the sieve plate 3, the sieve plate 3 rotates downward under the action of gravity. In this cycle, the sieve plate 3 can rotate up and down, thereby improving the dust screening efficiency of the sieve plate 3.
[0021] The driving mechanism 6 includes a motor 62, which is fixedly mounted on the outside of the housing 1. The output shaft of the motor 62 is fixedly connected to a transmission gear 63. The end of the hollow shaft 4 is fixedly connected to a gear ring 61, which meshes with the transmission gear 63. By starting the motor 62 to rotate the transmission gear 63, the gear ring 61 rotates synchronously, which also rotates the hollow shaft 4, so that the cam 5 drives the screen plate 3 to rotate intermittently upward, thereby improving the dust screening efficiency of the screen plate 3.

[0023] Water is introduced into the spray pipe 92 through the water inlet pipe 91, and water mist is sprayed through two nozzles 93 to contact the dust, so that the dust is dissolved in the water, thereby absorbing and purifying the dust and preventing the dust from drifting into the air and causing pollution. The driving mechanism 6 drives the hollow shaft 4 to rotate, and the two spray pipes 92 will rotate circumferentially with the hollow shaft 4, so that the nozzle 93 can spray water evenly into the interior of the box 1, so that the water mist is in even contact with the dust, thereby improving the dust purification effect.
