Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, specifically relating to a screening and transportation device for sand and gravel aggregates in mining. Background Technology

[0002] Mining sand and gravel aggregates are aggregate materials extracted from mines and processed through crushing for use in construction, roads, bridges, and other engineering fields. Natural sand and gravel aggregates are obtained directly from nature, such as river sand, mountain sand, and pebbles. Their characteristics include uneven resource distribution, and mining may have a certain impact on the environment. Mechanized sand and gravel aggregates are processed from rocks through mechanical crushing and screening processes. They have advantages such as controllable particle shape, stable quality, and abundant resources, and are gradually becoming an important source of sand and gravel aggregates. After being crushed, mining sand and gravel aggregates need to be screened promptly to intercept aggregates that do not meet usage requirements and re-crush them to the required size before transportation. Therefore, screening is always performed before transportation. Current screening systems are mostly vertical, relying on the natural flow of aggregates to reduce the cost of conveying equipment. However, it is inconvenient to clean the intercepted aggregates within the high-level screening mesh, resulting in slow cleaning efficiency due to the height issue. Therefore, the inventor proposes a screening and transportation device for mining sand and gravel aggregates. Utility Model Content

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model features a high-efficiency screening system. Through the combination of a swaying frame and a screen, screening can be performed simultaneously during the transport of sand and gravel aggregates. This separates aggregates that meet the particle size requirements from larger particles that do not, improving screening efficiency and reducing the workload of subsequent separate screening. Driven by a motor and screw, the cleaning plate automatically slides along the upper surface of the screen, cleaning larger particles left on the screen. This reduces the intensity and frequency of manual cleaning; only the concentrated aggregate needs to be cleaned. The design of the contact rod, moving block, and spring provides buffering and resetting when the cleaning plate contacts the baffle, protecting both the cleaning plate and the baffle, extending the equipment's service life, and ensuring the normal reciprocating motion of the cleaning plate. Integrating screening, transport, and cleaning functions into one device reduces the equipment's footprint and investment costs, improving the integration and automation of the entire production process, and ultimately enhancing the production efficiency and quality of sand and gravel aggregates in the mine.

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] This specific embodiment is a screening and conveying device for sand and gravel aggregates in a mine, and its structural schematic diagram is shown below. Figure 1 As shown, the system includes a conveyor platform 1, a swaying frame 3, and a support frame 2. A conveyor belt 4 is located inside the conveyor platform 1. Two sets of spaced-apart swaying frames 3 are located above the conveyor platform 1, with the support frame 2 positioned between the swaying frames 3. A screen 18 is located inside the swaying frame 3, and a cleaning plate 5 is located on one side of the swaying frame 3. The cleaning plate 5 slides along the upper surface of the screen 18. An opening is located on the side of the swaying frame 3 away from the cleaning plate 5, flush with the upper surface of the screen 18. A baffle 6 is located inside the opening, and two contact rods 9 protrude from the surface of the baffle 6 facing the cleaning plate 5. A top block 19 is located on the surface of the cleaning plate 5 facing the contact rods 9.

[0024] Reference Figure 3 A fixed frame 16 is fixedly installed on the outer wall of the conveyor table 1. An inner slide groove 14 is horizontally opened on the side wall of the fixed frame 16. A telescopic cylinder 15 is embedded inside the inner slide groove 14. The telescopic end of the telescopic cylinder 15 is fixedly connected to the bottom of the support frame 2. The support frame 2 slides along the inner slide groove 14, causing the swaying frame 3 above to slide synchronously.

[0025] Reference Figure 2 , Figure 4 An inner sliding groove 14 is horizontally formed on the inner wall of the shaking frame 3. Both the contact rod 9 and the inner sliding groove 14 are located within the moving groove 17. A moving block 8 protrudes from the upper surface of the contact rod 9. A reset groove is horizontally formed at the top of the inner wall of the moving groove 17. The moving block 8 slides inside the reset groove, and a spring 7 is fixedly connected to one side of the moving block 8. The end of the spring 7 away from the moving block 8 is fixedly connected to the inner wall of the reset groove. A drive screw 10 is horizontally rotatably mounted on the side wall of the shaking frame 3. One end of the drive screw 10 is threadedly connected to the cleaning plate 5, and the other end is rotatably connected to a fixing block 11. The fixing block 11 is fixedly connected to the shaking frame 3. A drive motor 12 connected to the drive screw 10 is mounted on the shaking frame 3.

[0026] Working principle: The sand and gravel aggregates are placed on the conveyor belt 4 of the conveyor platform 1. As the conveyor belt 4 moves, the sand and gravel aggregates enter the area of ​​the shaking frame 3. The inner side of the shaking frame 3 is equipped with a screen 18. The sand and gravel aggregates are screened under the action of the shaking frame 3. Driven by the extension and retraction of the telescopic cylinder 15, the aggregates that meet the particle size requirements pass through the screen 18 and continue to move with the conveyor belt 4, while the larger particles that do not meet the requirements remain on the upper surface of the screen 18.

[0027] A cleaning plate 5 is provided on one side of the shaking frame 3. The cleaning plate 5 moves horizontally through the cooperation of the drive screw 10 and the drive motor 12. When the drive motor 12 runs, it drives the drive screw 10 to rotate. Since the cleaning plate 5 is threadedly connected to the drive screw 10, and under the limiting action of the side wall of the shaking frame 3, the cleaning plate 5 slides along the upper surface of the screen 18, pushing the larger particles left on the upper surface of the screen 18 to the opening on the other side of the shaking frame 3.

[0028] When the cleaning plate 5 moves to the baffle 6 near the opening, the top block 19 on the cleaning plate 5 contacts the contact rod 9 on the baffle 6. The contact rod 9 is equipped with a moving block 8, which slides in the reset groove at the top of the inner wall of the moving groove 17 and is connected to a spring 7. The top block 19 pushes the contact rod 9, causing the moving block 8 to compress the spring 7 in the reset groove. At this time, the baffle 6 unfolds, and the cleaning plate 5 pushes the sand and gravel to the side of the shaking frame 3, which can concentrate the cleaning of the sand and gravel aggregate, effectively improving the convenience of cleaning. When the cleaning plate 5 returns after completing the cleaning action, the elastic force of the spring 7 causes the contact rod 9 to reset, so that the baffle 6 closes the opening again and the shaking frame 3 closes.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
