Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a heavy screening tracked station. Background Technology

[0002] In basic industrial sectors such as mining, metallurgy, building materials, and transportation construction, heavy-duty vibrating screens (hereinafter referred to as "heavy screens") are indispensable key equipment, mainly used for grading, dewatering, and demediuming of materials with large particle size and high specific gravity. Traditional heavy-duty screening equipment is usually a large, integrated steel structure, and its core design focuses on ensuring screening efficiency, processing capacity, and structural strength to meet long-term stable operation under harsh working conditions.

[0003] However, this traditional design also results in equipment that is enormous in size and incredibly heavy. Its inherent "bulky" nature leads to a prominent industry pain point: difficulty in relocating the equipment and extremely poor flexibility. In actual construction, when the task at one work site is completed and the heavy-duty screen needs to be moved to a new location, the existing relocation process is extremely cumbersome. It usually requires the use of large lifting equipment (such as crawler cranes) for overall hoisting and transport, or more commonly, the equipment must be partially or completely disassembled into multiple components, transported separately to the new site, and then reassembled and tested. This process not only requires a significant investment of manpower, resources, and time (usually taking 3 to 5 days), but the frequent disassembly and reassembly can also easily damage the equipment's precision, affecting its service life and stability.

[0004] This inefficient relocation method directly leads to a significant loss of effective equipment operating time, resulting in heavy-duty screens generally operating at less than 60% utilization. A large amount of time is consumed in non-productive relocation, installation, and commissioning processes, rather than the value-creating screening operations themselves. This not only significantly increases the overall operating costs of the project but also greatly restricts the demands of modern construction that require rapid response and multi-point, multi-faceted operations.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0025] Please see the appendix Figure 1-10 This embodiment of the heavy screening tracked station includes a mobile frame 1, on which a heavy-duty screen 2 is hinged. A first adjusting support rod 3 is installed between the heavy-duty screen 2 and the mobile frame 1. A plate chain feeder 4 is provided on one side of the heavy-duty screen 2, and an adjusting slide 5 is installed below the plate chain feeder 4. A coarse material discharge rack 6 is provided on the other side of the heavy-duty screen 2. The heavy-duty screen 2 and the coarse material discharge rack 6 are placed in a V-shaped structure. A discharge screen plate 7 and a transition belt conveyor 8 are provided inside the heavy-duty screen 2. The discharge screen plate 7 is located above the transition belt conveyor 8. A first folding belt frame 9 is provided at the discharge port of the transition belt conveyor 8. A second folding belt frame 10 is provided at the discharge port of the discharge screen plate 7. Belt conveyors are installed on the first folding belt frame 9, the coarse material discharge rack 6, and the second folding belt frame 10. The first folding belt frame 9 and the second folding belt frame 10 surround the heavy-duty screen 2 in an n-shape.

[0026] The mobile frame 1 is a boat-shaped structure with a downward convex center and upward curved sides. It is welded from Q355 steel plates. Tracked wheels are installed at the bottom of the mobile frame 1, and the frame is equipped with a drive mechanism for moving the tracked wheels and an oil tank. The tracked wheels and their connecting structures adopt existing technical structures. The heavy-duty screen 2 is a screening component. The heavy-duty screen 2 is installed on the mobile frame 1 above the tracked wheels. The heavy-duty screen 2 is installed at an angle on the mobile frame 1. The structure and function of the heavy-duty screen 2 are the same as existing screening structures. The heavy-duty screen 2 plays the role of material screening. In this application, the feed screen plate 7 below the heavy-duty screen 2 has screen holes. The diameter of the screen holes is smaller than the diameter of the target material. The transition belt conveyor 8 is located below the feed screen plate 7. The transition belt conveyor 8 is also placed at an angle. Its purpose is to receive the material passing through the screen holes of the feed screen plate 7. The transition belt frame has a motor and a drive roller. The motor and drive roller drive the transition belt conveyor 8 to work.

[0027] Specifically, during operation, the device uses a loader or other material handling components to shovel materials into the plate chain feeder 4. The plate chain feeder 4 then gradually conveys the materials to the heavy-duty screen 2 via its internal plate chain. The heavy-duty screen 2 vibrates at high frequency during operation. Through vibration and its inclined placement, the materials are screened along the upper screen. Oversized particles flow from above the screen to the coarse material discharge rack 6, while undersized particles pass through the screen into the lower feed screen plate 7. The screen holes on the feed screen plate 7 filter the undersized particles again, allowing particles that meet the target to flow from above the feed screen plate 7 to the second folding belt frame 10. Undersized particles, after entering the transition belt conveyor 8, then enter the first folding belt frame 9 via the material belt conveyor. The first folding belt frame 9, the second folding belt frame 10, and the coarse material discharge rack 6 all have belt conveyors. These belt conveyors have the same structure as existing material conveyor belts and serve the purpose of transferring materials.

[0028] Furthermore, the tilt angle of the heavy-duty screen 2 on the mobile frame 1 is adjustable, such as... Figure 1 As shown, the right side of the heavy-duty screen 2 is hinged to the mobile frame 1, and the left side of the heavy-duty screen 2 is hinged to the mobile frame 1. The first adjusting support rod 3 is a hydraulic adjusting rod, and its length can be adjusted by the hydraulic system. During screening, the height of the first adjusting support rod 3 can be extended to raise the left side of the heavy-duty screen 2, increasing its slope and ensuring that the material slides down for screening quickly, thus improving screening efficiency. On the other hand, when not in operation, the length of the first adjusting support rod 3 can be reduced to decrease its slope, and the heavy-duty screen 2 can be placed flat against the mobile frame 1, thereby reducing the overall height of the device and facilitating its movement.

[0029] The plate chain feeder 4 moves synchronously with the heavy-duty screen 2 by adjusting the slide 5, such as... Figure 3 As shown, a support column 502 is fixedly connected to the heavy-duty screen 2. The support column 502 has an L-shaped structure and is hinged to the left end of the plate chain feeder 4. The right end of the plate chain feeder 4 is supported by rollers 505. When the heavy-duty screen 2 moves downward or upward, the left end of the plate chain feeder 4 also moves downward or upward synchronously. The cooperation between the right side slide groove 504 and the rollers 505 of the plate chain feeder 4 provides compensation for the movement of the plate chain feeder 4 and ensures that there is no interference during its movement. In addition, there is a sliding sleeve 503 on the plate chain feeder 4. The sliding sleeve 503 is slidably connected to the sliding rod 501. At the same time, the rollers 505 can also slide horizontally in the slide groove 504. The plate chain feeder 4 can also be slidably adjusted to ensure that the discharge port of the plate chain feeder 4 can penetrate deep into the heavy-duty screen 2.

[0030] Furthermore, the roller 505 can be an electromagnetic roller 505. The roller 505 is connected to the frame via a connecting shaft, and a drive motor is connected to the connecting shaft. When the drive motor is working, it drives the plate chain feeder 4 to slide horizontally through the connecting shaft and the roller 505.

[0031] Both the first folding belt frame 9 and the second folding belt frame 10 have two folding points. Taking the first folding belt frame 9 as an example: the first folding belt frame 9 is composed of a first support 901, a second support 902, and a third support 903. The first support 901 is hinged to the moving frame 1 and receives fine material from the transition belt conveyor 8 through the hopper. A first telescopic rod 904 is hinged between the lower part of the first support 901 and the moving frame 1. The tilt angle of the first support 901 is changed by the extension and retraction of the first telescopic rod 904. Similarly, ... Figure 7 and Figure 9 As shown, the second support 902 is hinged to the first support 901, and the second support 902 is hinged to the second support 902. When the release angle of the first support 901 changes, the second support 902 and the third support 903 rotate synchronously with the first support 901. When the second support 902 needs to be adjusted, the length of the second telescopic rod 905 is adjusted, and the third support 903 rotates synchronously with the rotation of the second support 902. When the third support 903 needs to be adjusted, the length of the third telescopic rod 906 changes. At this time, only the angle of the third support 903 changes, so that the first folding belt frame 9 wraps around the side of the vibrating screen in an n-shape, reducing the space volume of the device when not in use and facilitating the movement and transfer of the device.

[0032] Furthermore, an overlapping plate 11 is installed below the plate chain feeder 4. One end of the overlapping plate 11 extends into the front end of the discharge screen plate 7. The overlapping plate 11 is located below the plate chain feeder 4 and is inclined towards the discharge screen plate 7. Its function is to collect the material carried on the plate chain feeder 4 and allow the material to enter the discharge screen plate 7 along the overlapping plate 11, thus avoiding material waste.

[0033] Furthermore, such as Figure 8 and Figure 10 As shown, the coarse material discharge rack 6 consists of an adjusting arm 601 and a folding arm 602. The adjusting arm 601 is used to adjust the overall tilt angle, while the folding arm 602 can rotate 180 degrees. When folded, the coarse material discharge rack 6 occupies less space and reduces the length of the device when moving, making it easier to move in narrow paths. The angle of the adjusting arm 601 is adjusted by the second adjusting support rod 603, while the rotation of the folding arm 602 is achieved by the cooperation of the first connecting rod 604, the second connecting rod 606 and the fourth telescopic rod 605.

[0034] The first telescopic rod 904, the second telescopic rod 905, the third telescopic rod 906, and the fourth telescopic rod 605 are all hydraulic rods. Their telescopic length is adjusted by a hydraulic system. The technologies used are all existing technologies and will not be elaborated on here.

[0035] 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.
