The vibrating screen for mining stone processing uses the vibration generated by the vibrator to make the screen box and the ore on the screen move. The ore is affected by gravity, friction and vibration force, and is layered and screened on the screen according to its particle size and shape, thereby achieving effective separation of ores of different particle sizes.

[0003] After searching, the Chinese patent announcement number is: CN209271534U, which discloses a vibrating screen for processing mining stones, including a frame and a shaking screen, the shaking screen is movably installed inside the frame, and both sides of the frame are fixedly connected to a support frame by screws, the top outer surface of the frame is fixedly connected to a processing box by screws, and the inside of the processing box is movably installed with an auxiliary screen near the frame, the top outer surface of the processing box is fixedly installed with a feed port, and the inside of the processing box is movably installed with a fixed roller and a squeezing roller away from the frame. In this utility model, the mining stone can be squeezed when rotating to break it into small pieces, and the size of the squeezed mining stone can be adjusted to meet the processing requirements of mining stones of various sizes, and the mining stone that has not been broken into small pieces can be tilted and poured out to prevent some mining stones that are too large to be screened from easily clogging and gravity-pressing the shaking screen, causing inconvenience in cleaning and disassembly and reducing the service life of the shaking screen. However, when the equipment is feeding, the stone directly enters the feed hole, generating a large amount of dust and drying the surface of the stone, which is not conducive to the crushing device to crush it. The dry stone will cause the feed hopper to be blocked, affecting the overall efficiency of the equipment. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a vibrating screen for mining stone processing, which aims to improve the problem of clogging the hopper caused by the excessive dryness of the surface of the stone when it directly enters the hopper in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a vibrating screen for mining stone processing, comprising a body, a feed hopper fixedly connected to the top rear side of the body, a support plate fixedly connected to the middle of the front side of the outer wall of the feed hopper, a slide groove is provided on the top of the support plate, a pulley is slidably connected to the inside of the slide groove, a water pump is fixedly connected to the top of the pulley, one end of the water pump is connected to a water inlet pipe, and the other end of the water pump is connected to a nozzle pipe, a fixed block is fixedly connected to the top left side of the support plate, an electric push rod is fixedly connected to the right side of the outer wall of the fixed block, the other end of the electric push rod is fixedly connected to the middle of the left side of the outer wall of the water pump, and a dust removal mechanism is fixedly connected to the external front side of the body, and the dust removal mechanism is used to process dust generated when the equipment is working.

[0006] Through the above technical solution: during the ore screening operation, the stone is poured from the feed hopper into the vibrating screen, the water pump is started, and water is introduced from the water inlet pipe. Driven by the water pump, the water is sprayed out through the nozzle pipe, so that the water flow is transformed from liquid to mist, which can not only effectively wet the surface of the stone, but also reduce the initial diffusion of dust to a certain extent, thereby improving the working environment and enabling operators to work in a cleaner environment. The electric push rod is started. When the electric push rod is in working state, it drives the movement of the pulley through mechanical transmission. Under the limiting action of the chute, the pulley enables the water pump to move left and right within the range of the chute, thereby achieving an all-round infiltration effect on the stone and improving the efficiency and quality of the entire ore processing process.

[0007] As a further description of the above technical solution:

[0008] The dust removal mechanism includes a connecting plate, which is fixedly connected to the upper and middle part of the front side of the outer wall of the body, and a fan is fixedly connected to the middle part of the top wall of the connecting plate.

The left and right ends of the front side of the outer wall of the body are fixedly connected to electric motors, and the output end of the motor is fixedly connected to a rotating fan.

[0009] Through the above technical solution: after the stone is carefully screened by the vibrating screen, the operator starts the fan. As the fan starts, its force causes the dust to begin to enter from the air inlet. The dust is then guided to the air duct and finally reaches the dust collection bag for effective collection. At the same time, the motor is started. The operation of the motor drives the rotation of the rotary fan, which lifts the dust upward and brings it into the range of action of the fan. The fan can more effectively inhale the raised dust, thereby significantly enhancing the dust collection effect. The cooperation of the motor and the rotary fan enables the dust to be effectively lifted and inhaled into the fan, thereby reducing the diffusion of dust in the air.

[0019] As a further description of the above technical solution:

[0020] A transverse groove is provided in the middle of the front and rear sides of the inner wall of the feeding hopper, and a slide plate is slidably connected inside the transverse groove.

[0021] Through the above technical solution: by sliding the slide plate inside the transverse groove, the feeding rate of the hopper can be controlled, and the feeding rate can be adjusted to ensure the smoothness and efficiency of the entire production process.

[0022] As a further description of the above technical solution:

[0023] Lamp holders are fixedly connected to the middle parts of the left and right sides of the outer wall of the machine body, and a light bulb is installed on the top of the lamp holder.

[0024] Through the above technical solutions: the light bulb can provide a clear view and a bright environment in a dark working environment, improve the practicality of the equipment, and ensure the smooth progress of various tasks.
