[0002] Mining refers to the business of mining underground minerals, involving the exploitation of underground or surface mineral resources, which include naturally occurring minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). Mining activities include not only underground or above-ground excavation and mine operation, but also raw material processing (such as crushing, ore dressing and treatment) at or near the mine site and preparations for the sale of raw materials. Mining is an important industrial sector that uses nature as its labor object and obtains natural resources through mining and logging. The main areas include coal industry, petroleum industry, salt industry, etc. Mineral resources are the product of the earth's crust in its long-term formation, development and evolution process, including metals, non-metals, combustible organic and other categories of resources. They are usually classified as energy minerals, metal minerals, non-metallic minerals and water and gas minerals.

[0003] It is difficult to ensure that the size of solid minerals is consistent after mining, so the ore needs to be screened and classified. Most existing screening devices directly expose the minerals to the outside, and a large amount of dust is easily generated during the screening process to pollute the environment. The relatively closed screening devices have a high degree of integrity and are inconvenient to disassemble and overhaul, which can also easily affect the continuity of ore screening.

[0021] The utility model provides a combined vibrating screen. Figure 1-4 As shown, the combined vibrating screen includes: a base 1, a plurality of support rods are installed on the top of the base 1; a plurality of hydraulic rods 2, the plurality of hydraulic rods 2 are hinged on the top of the base 1; a screening box 3, the screening box 3 is hinged on the output rods of the plurality of hydraulic rods 2, and the screening box 3 is hinged with the plurality of support rods; a plurality of springs 4, the plurality of springs 4 are installed in the screening box 3; a support plate 5, the support plate 5 is installed on the top of the plurality of springs 4, at least two openings are provided on the support plate 5, a first screen 6 and a second screen 7 are respectively installed in the two openings, and the mesh sizes of the first screen 6 and the second screen 7 are inconsistent; two dust suction assemblies, the two dust suction assemblies are arranged on the screening box 3, and the dust suction assemblies are used to absorb dust generated by screening ore.

[0022] In this embodiment, the base 1 serves as the supporting structure of the entire vibrating screen and is connected to the screening box 3 through a supporting rod and a hydraulic rod 2. The setting of the hydraulic rod 2 enables the height and inclination angle of the screening box 3 to be adjusted as needed to adapt to different screening requirements. The spring 4 and the support plate 5 in the screening box 3 together constitute a vibrating screening system. When the ore enters the screening box 3, the ore on the support plate 5 is screened under the action of the spring 4, and ores of different sizes are respectively classified through the first screen 6 and the second screen 7. The first screen 6 and the second screen 7 can achieve screening of ores of different particle sizes, and the dust suction component effectively solves the dust problem generated during the screening process and reduces pollution to the environment.

[0023] In a further preferred embodiment of the utility model, slide grooves are provided on both sides of the screening box 3, and multiple sliders 8 are slidably installed in the two slide grooves. The same dustproof shell 9 is fixed on the multiple sliders 8, and the dustproof shell 9 is mounted outside the top opening of the screening box 3.

[0024] In this embodiment, when vibration screening is performed inside the screening box 3, the dustproof cover 9 can block most of the dust from spreading outward, thereby significantly improving the working environment and reducing pollution to the surrounding environment. The sliding installation method of the slider 8 and the slide groove allows the dustproof cover 9 to be easily adjusted in position or removed for cleaning and maintenance as needed. This design takes into account both the ease of use of the equipment and the long-term stable operation of the equipment.

[0025] In a further preferred embodiment of the utility model, the dust suction assembly includes a fan 10, a dust box 11, an air inlet pipe 12, a dust suction pipe 13 and a mesh cover 14, the fan 10 and the dust box 11 are both fixedly mounted on the top of the dustproof shell 9, the dust box 11 is fixedly connected to the air inlet end of the fan 10, the air inlet pipe 12 is mounted on the side of the dust box 11 away from the fan 10, the dust suction pipe 13 is fixedly mounted on the air inlet end of the air inlet pipe 12, and the mesh cover 14 is sleeved outside the dust suction pipe 13.

[0026] In this embodiment, the fan 10 can smoothly draw air from the dust box 11, and suck in the dust generated in the screening box 3 through the cooperation of the air inlet pipe 12 and the dust suction pipe 13. The dust box 11 is fixedly connected to the air inlet end of the fan 10, ensuring that the suction force of the fan 10 can be effectively transmitted to the dust suction pipe 13. The dust suction pipe 13 is located inside the screening box 3 so as to capture the generated dust to the greatest extent. The mesh cover 14 can not only prevent large pieces of ore or debris from entering the dust suction pipe 13 and causing blockage or damage to the fan 10, but also increase the dust suction area to a certain extent, thereby improving the dust suction efficiency.

[0027] In a further preferred embodiment of the utility model, an opening is provided on one side of the screening box 3, and a discharge port is provided at the bottom of the screening box 3, and the discharge port is located below the first screen 6. Two collecting boxes 18 are placed on the base 1, and the two collecting boxes 18 are respectively located at the bottom of the opening and the discharge port, and universal wheels 19 are provided at the bottom of the two collecting boxes 18.

[0028] In this embodiment, the two collecting boxes 18 can respectively collect ores of different particle sizes discharged from the opening and the discharge port. This design not only facilitates the classification and collection of ores, but also improves the efficiency of screening operations. The setting of the universal wheel 19 makes the movement of the collecting box 18 more flexible and convenient. The operator can easily push the collecting box 18 to the designated position as needed, thereby further improving the convenience of the screening operation.

[0029] In a further preferred embodiment of the utility model, baffles can be detachably installed on the two dust boxes 11, dust bags are fixed on the two baffles, the two dust bags are respectively located in the two dust boxes 11, observation windows are provided on the two dust boxes 11, and the two dust suction pipes 13 are respectively located on both sides of the dustproof shell 9.

[0030] In this embodiment, when the dust in the dust box 11 accumulates to a certain extent, the operator can easily remove the baffle and clean the dust box 11, thereby ensuring the continuous and efficient operation of the dust collection assembly. The provision of the dust bag not only increases the dust collection capacity, but also makes the dust collection more concentrated and convenient. When the dust bag is full of dust, the operator can simply replace it with a new one without disassembling and cleaning the entire dust collection assembly. Through the observation window, the operator can intuitively understand the dust accumulation in the dust box 11, thereby arranging the cleaning work in time to ensure the normal operation of the dust collection assembly.

[0031] In a further preferred embodiment of the utility model, multiple motors are installed on both sides of the screening box 3, and multiple rotating shafts 15 are rotatably installed in the screening box 3. The multiple rotating shafts 15 are respectively fixedly connected to the output shafts of the multiple motors, and the multiple rotating shafts 15 are fixed with cams 16 that can contact the support plate 5.

[0032] In this embodiment, through the coordinated use of the motor and the rotating shaft 15, the vibration drive of the internal support plate 5 of the screening box 3 is realized, thereby improving the screening efficiency and screening quality. The setting of the cam 16 makes the vibration more uniform and continuous, which helps to reduce blockage and jamming during the screening process and improves the stability and reliability of the screening process.

[0033] In a further preferred embodiment of the utility model, a plurality of cams 16 are fixedly sleeved with a shock-absorbing sleeve outside, a plurality of springs 4 are provided with a limiting telescopic rod 17 inside, and a non-slip pad is provided at the bottom of the base 1.

[0034] In this embodiment, the vibration noise generated when the cam 16 contacts the support plate 5 can be reduced by the shock-absorbing sleeve, thereby improving the stability and comfort of the screening process. The use of the shock-absorbing sleeve can effectively absorb and disperse the vibration energy, reduce the impact of the support plate 5, and thus extend the service life of the equipment. The setting of the limiting telescopic rod 17 is intended to enhance the stability and supporting force of the spring 4. During the screening process, the spring 4 will be subjected to greater compression and tension, and the limiting telescopic rod 17 can effectively limit the deformation range of the spring 4 to prevent it from excessive deformation or failure. This not only improves the stability of the screening process, but also ensures that the support plate 5 always maintains an appropriate vibration amplitude, thereby improving the screening efficiency.

[0035] To sum up, compared with the relevant technology, the device can protect the ore screening environment by setting the dustproof shell 9, effectively reduce the diffusion of dust, so as to achieve the effect of protecting the environment, and at the same time, the dustproof shell 9 is stabilized by the slider 8 to effectively increase the flexibility of the dustproof shell 9, and the dustproof shell 9 can be pushed open when the screening box 3 needs to be cleaned, and the dust suction component can be provided to more effectively absorb the dust generated during feeding and discharging, and the ore can be graded and screened by setting sieves with different apertures, and the screening box 3 can be tilted by adjusting the output rod extension length of the hydraulic rod 2, so that the ore can be moved during the screening process, thereby facilitating the discharging, and the support plate 5 can be moved back and forth up and down by providing the spring 4, the motor, the rotating shaft 15 and the cam 16, so as to improve the screening efficiency of the ore.
