Description

Technical Field

[0001] This utility model relates to the field of ore, rock and soil screening technology, specifically to an ore, rock and soil screening device for mine construction. Background Technology

[0002] Mine construction is a systematic project centered on mineral resource development, encompassing the entire lifecycle of technical activities from exploration to production. During the mine construction process, screening devices are needed to screen the ore and soil on the ground, thereby classifying the ore and soil to facilitate their later utilization or transportation.

[0003] In existing technologies, ore and soil screening devices are commonly used in mine construction. These devices typically refer to roller screens, which are high-efficiency material grading equipment that play a crucial role in mining, coal, and construction waste treatment. The continuously rotating rollers screen ores and soils. The rollers transport the ore, while the gaps between them screen the soil and rock. During operation, a conveyor is usually placed at the bottom inside the screening device to transport the screened soil and rock. Since the screened soil and rock typically fall directly onto the conveyor, and there is a certain distance between the top of the conveyor and the top of the inner side of the screening device, dust is easily generated during the fall, which can affect nearby workers and the surrounding construction environment. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 and Figure 4It is understood that this utility model provides a technical solution: a screening device for ore and soil in mining construction, comprising: a screening machine body 1, a feed hopper 2, a drive motor 3, a screening roller 4, and an ore guide hopper 5. The feed hopper 2 is connected to the top inner side of the screening machine body 1, the drive motor 3 is installed on the outer side of the screening machine body 1, the output end of the drive motor 3 is connected to the screening roller 4, the ore guide hopper 5 is connected to the side of the screening machine body 1 near the drive motor 3, the soil guide hopper 6 is welded to the bottom of the screening machine body 1, the bottom of the soil guide hopper 6 is bolted with a bellows telescopic cover 7, a first connecting rod 8 is connected to one side of the bellows telescopic cover 7, and a first fixing block 9 is welded to the bottom of the screening machine body 1 near the first connecting rod 8.

[0024] The ore and soil screening device used in the mine construction, including the soil and rock guide hopper 6 and the bellows telescopic cover 7, can prevent dust from scattering.

[0025] exist Figures 1-3 In the middle: The inside of the second fixed block 10 is connected to a threaded rod 11 via a bearing. The outside of the threaded rod 11 is threadedly connected to a movable plate 12. The movable plate 12 and the outside of the bellows telescopic cover 7 are connected to a second connecting rod 13. A support plate 14 is welded to the outside of the second fixed block 10. A forward and reverse motor 15 is installed on the surface of the support plate 14. The rotating shaft of the forward and reverse motor 15 and the outside of the threaded rod 11 are both connected to rotating wheels 16. A synchronous belt 17 is sleeved between the two rotating wheels 16.

[0026] The ore and soil screening device used in this mine construction has a synchronous belt 17 that can drive two sets of rotating wheels 16 to rotate.

[0027] exist Figure 3 and Figure 4 In the middle: the movable plate 12 and the second fixed block 10 form a sliding structure, and the first connecting rod 8 and the second connecting rod 13 have the same shape.

[0028] The position of the movable plate 12 in this mine construction ore and soil screening device can be adjusted according to the actual situation.

[0029] In practical implementation, the ore and soil screening device is mainly used for screening ore and soil. Traditional screening devices, when in use, can easily generate dust from falling soil, which can affect the surrounding working environment and personnel. Before using the screening device, the conveyor can be placed on the ground below the inner side of the main body 1 of the screening machine (not shown in the diagram). At this time, the forward and reverse motor 15 can be started. When the forward and reverse motor 15 rotates forward, it drives a set of rotating wheels 16 to rotate via the rotating shaft. When the set of rotating wheels 16 rotates, it drives the synchronous belt 17 to rotate. When the synchronous belt 17 rotates, it drives the threaded rod 1... Another set of rotating wheels 16 on 1 rotates. When the rotating wheels 16 on the threaded rod 11 rotate, they can drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, it can drive the moving plate 12 to slide in a threaded direction away from the rotating wheels 16. When the moving plate 12 moves, it can drive the second connecting rod 13 to move. When the second connecting rod 13 moves, it can drive the bottom end of the bellows telescopic cover 7 to move away from the rock and soil guide hopper 6. When the bellows telescopic cover 7 moves, it can drive the first connecting rod 8 to slide inside the first fixed block 9. When the bellows telescopic cover 7 moves, it can be unfolded.

[0030] See Figures 1-4 It can be seen that when the bottom of the bellows telescopic cover 7 moves to the surface above the conveyor, the rock and soil guide hopper 6 and the bellows telescopic cover 7 can block the path of the falling rock and soil. During the falling process, the rock and soil guide hopper 6 and the bellows telescopic cover 7 can block the dust generated during the falling rock and soil, thereby effectively preventing the dust in the rock and soil from being scattered, and making the surrounding working environment and personnel less likely to be polluted and affected by dust.

[0031] exist Figure 1 , Figure 2 and Figure 6 In the middle: A support frame 18 is welded to the top of the main body 1 of the screening machine. A through hole 19 is opened through the inside of the support frame 18. A fixed shaft 20 is connected to the top of the support frame 18. A rotating block 21 is rotatably connected to the outside of the fixed shaft 20. A threaded knob 22 is threadedly connected inside the rotating block 21.

[0032] The ore and soil screening device used in mine construction has a threaded knob 22 that can fix the rotating block 21.

[0033] exist Figure 1 , Figure 2 and Figure 5 In the middle: a protective plate 23 is provided on the inner side of the screening machine body 1, a plug-in plate 24 is connected to the top of the protective plate 23, a limit plate 25 is connected to the outer side of the plug-in plate 24, and a groove 26 is provided inside the plug-in plate 24.

[0034] The protective plate 23 of the ore and soil screening device used in the mine construction can prevent stones from flying out from the inside of the screening machine body 1 and injuring the surrounding workers.

[0035] In practice, when using the ore and soil screening device, the stones on the screening roller 4 may collide and bounce due to excessive rotation speed, causing stones inside the screening machine body 1 to easily fly out from the top inside, posing a certain safety hazard. Before using the screening device, the protective plate 23 can be moved to the inside of the screening machine body 1, and the plug plate 24 on the protective plate 23 can be pushed towards the corresponding through hole 19. When the end of the plug plate 24 passes through the through hole 19 and penetrates the support frame 18, the limiting plate 25 on the plug plate 24 can be moved to the bottom inside the support frame 18. At this time, the two sets of rotating blocks 21 can be pulled towards the groove 26 respectively. When the rotating block 21 moves, it can be rotated through the fixed shaft 20. When the rotating block 21 rotates into the groove 26, the threaded knob 22 can be tightened so that the threaded knob 22 can slide into the support frame 18. At this time, the plug plate 24 can fall on the rotating block 21.

[0036] See Figure 1 , Figure 2 , Figure 5 and Figure 6 It can be seen that the rotating block 21 can be fixed on the support frame 18, thereby installing the protective plate 23 above the main body 1 of the screening machine. The protective plate 23 can effectively prevent stones from flying out from the inside of the main body 1 of the screening machine, thereby improving the safety of the ore and soil screening device during use.

[0037] In summary, when using this ore and soil screening device for mine construction, when the forward and reverse motor 15 rotates forward, it drives a set of rotating wheels 16 to rotate via the rotating shaft. When the set of rotating wheels 16 rotates, it drives the synchronous belt 17 to rotate. When the synchronous belt 17 rotates, it drives another set of rotating wheels 16 on the threaded rod 11 to rotate. The soil and rock guide hopper 6 and the bellows telescopic cover 7 can block the path of the falling soil and rock, so that the soil and rock guide hopper 6 and the bellows telescopic cover 7 can block the dust generated during the falling soil and rock, thereby effectively preventing the dust in the soil and rock from being scattered. This makes it less likely for the surrounding working environment and personnel to be contaminated and affected by dust. The protective plate 23 can effectively prevent stones from flying out from the inside of the screening machine body 1, thereby improving the safety of the ore and soil screening device during use. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
