Description

Technical Field

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

[0002] In the field of material screening, vibrating screens, as a key screening equipment, are widely used in many industries such as mining, building materials, chemicals, and food processing. Their working principle mainly utilizes the excitation force generated by a vibrating motor to cause the screen body to vibrate periodically. The material undergoes a throwing motion on the screen surface. Depending on the particle size, particles smaller than the screen aperture pass through the apertures and become the undersize, while particles larger than the aperture remain on the screen surface and become the oversize, thus achieving the screening objectives of material grading, dewatering, and desliming.

[0003] Currently, most existing vibrating screens only have a single-stage screening function. During material screening, they can only simply separate materials into two categories: target materials and waste. For example, in ore processing, after primary screening by a vibrating screen, ore meeting the particle size requirements is collected as target material, while ore that does not meet the size requirements is treated as waste. However, this waste may actually contain various materials of different particle sizes or properties. Treating them together makes it impossible to perform subsequent refined and targeted processing for waste with different characteristics. For instance, in the coal washing industry, the waste after primary screening may contain both large pieces of gangue and smaller coal-gangue mixtures that still have some calorific value. Treating them together not only wastes usable resources but also increases processing costs and environmental burden.

[0004] Furthermore, because existing vibrating screens only have a single screening stage, the separation of target materials from waste is not thorough enough during the screening process. Some target materials with particle sizes close to the screen aperture size are easily confused with waste during vibration, causing some target materials to be incorrectly classified as waste, thus reducing the output rate of target materials. Taking sand and gravel processing as an example, during the single-stage screening of a vibrating screen, some qualified sand and gravel with particle sizes slightly smaller than the screen aperture size may be discharged along with the waste. This not only wastes resources but also affects the economic benefits of sand and gravel production enterprises. Moreover, as various industries continue to raise the requirements for material quality, this problem of low output rate is becoming increasingly prominent, failing to meet the market demand for high-quality, high-purity target materials.

[0020] 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.

[0021] Please see the appendix Figure 1-6 In this embodiment, the vibrating screen track station includes a mobile frame 1, a material conveying frame 2 connected above the mobile frame 1, a vibrating screen 3 with three material inlets below the discharge area of ​​the material conveying frame 2, one end of the vibrating screen 3 being hinged to the mobile frame 1, and the other end of the vibrating screen 3 being hinged to a first adjusting rod 4, which is hinged to the mobile frame 1. A material discharge frame 5 is provided below the vibrating screen 3, which is hinged to the mobile frame 1, and a fine material conveyor belt 6 is installed inside the material discharge frame 5. The vibrating screen 3 includes a vibrator 301, a protective shell 302, and a spring 303. A first screen plate 304, a second screen plate 305, and a third screen plate 306 are fixedly connected inside the protective shell 302. The first screen plate 304, the second screen plate 305, and the third screen plate 306 are placed sequentially from top to bottom, and the screen hole diameters of the first screen plate 304, the second screen plate 305, and the third screen plate 306 gradually decrease.

[0022] The mobile frame 1 has a boat-shaped structure. Internally, it is constructed from welded steel plates and support beams. Tracked casters are mounted on the lower end of the mobile frame 1. The mobile frame 1 houses the powertrain and fuel tank, and the tracked casters drive the movement of the mobile frame 1 and its upper components. The mobile frame 1 is the main load-bearing component. Components such as the material conveying frame 2, vibrating screen 3, and material discharge frame 5 are all mounted on top of the mobile frame 1, providing stable support for the upper components. The vibrating screen 3 is angle-adjustable on the mobile frame 1. One end of the vibrating screen 3 is hinged to the mobile frame 1, and the middle of the vibrating screen 3 is supported by two first adjusting rods 4. The other end of the rod 4 is hinged to the moving frame 1. The first adjusting rod 4, the vibrating screen 3 and the moving frame 1 form a triangular structure. Under the premise that the length of the first adjusting rod 4 remains unchanged, the vibrating screen 3 is in a sufficiently stable state. When it is necessary to adjust the elevation angle of the vibrating screen 3, the length of the first adjusting rod 4 can be changed. The vibrating screen 3 has three layers of screen plates inside, and the screen holes of the three layers of screen plates are different. Below the vibrating screen 3 is the material discharge rack 5, which is used to receive the fine material that has passed through the three layers of screen plates. The finished fine material is continuously transported to one side by the fine material belt conveyor 6 on the material discharge rack 5, thereby transporting the screened finished fine material to a specific position.

[0023] The internal drive and damping components of the vibrating screen 3 are the same as those of existing mechanisms. The vibrating screen 3 is driven by the internal vibrator 301 to perform a reciprocating vibration. The spring 303 is a damping and rebound component. The protective shell 302 is welded from steel plates. The three screen plates are located on the first screen plate 304, the second screen plate 305, and the third screen plate 306, respectively. The three are placed parallel from top to bottom. The screen holes on the first screen plate 304 have the largest diameter, and the screen holes on the third screen plate 306 have the smallest diameter. The first screen plate 304, the second screen plate 305, and the third screen plate 306 are all placed at an angle, and their sides correspond to three different hoppers. The three hoppers correspond to three folding racks facing different directions. Through the cooperation of the three hoppers, the three screen plates, and the three folding racks, waste materials of different apertures are classified and transferred to different positions, which facilitates the subsequent waste processing work and also ensures improved material screening efficiency and avoids waste of finished fine materials.

[0024] Specifically, the three hoppers are the first hopper 7, the second hopper 9, and the third hopper 11. The first hopper 7 corresponds to the first folding rack 8, the second hopper 9 corresponds to the second folding rack 10, and the third hopper 11 corresponds to the third folding rack 12. The lowest point of the first folding rack 8 is lower than the height of the first hopper 7. Under the action of gravity, the screened material falls from the first hopper 7 into the first folding rack 8. A belt conveyor is installed in the first folding rack 8. The belt conveyor has the same structure as the existing transmission belt and moves the screened material from the low point to the high point by relying on the motor drive. The structures of the second folding rack 10 and the third folding rack 12 are the same as those of the first folding rack 8, and the principle of their cooperation is also similar, so they will not be described in detail here.

[0025] The first folding rack 8 can be folded laterally onto the side of the mobile frame 1. The first folding rack 8 consists of two parts. The first part is the first support 801, which is hinged to the mobile frame 1 in a tilting manner. The first support 801 can swing up and down relative to the mobile frame 1, thus adjusting the tilt angle of the first support 801 and the first folding rack 8 as a whole. The adjustment method is changed by the extension and retraction of the second adjusting rod 802. The other end of the first support 801 is rotatably hinged to the second support 803, which can swing left and right relative to the first support 801. The first folding rack 8 can be folded up and then rotated to the side by rotating the second rack 803, so that the first folding rack 8 can be stored sideways against the moving frame 1. The folding of the second rack 803 is adjusted by the third adjusting rod. Similarly, the structures of the second folding rack 10 and the third folding rack 12 are the same as those of the first folding rack 8. The folding and placement of the three racks makes the device smaller after storage, which facilitates the movement of the device and avoids collisions with obstacles during the transfer process.

[0026] The material conveying frame 2 is installed obliquely above the vibrating screen 3. The material conveying frame 2 consists of a third support 201 and a fourth support 202. The feeding area is on the third support 201, and there are guard plates around the feeding area. The guard plates are located on the three sides of the third support 201, and the guard plates serve to deepen the depth of the third support 201. The material is transferred into the third support 201 by a loader. The third support 201 and the fourth support 202 share a transmission belt. The material in the third support 201 moves upward through the transmission belt. The fourth support 202 can rotate vertically relative to the third support 201. The rotation angle is controlled by the fourth adjusting rod 804. The fourth support 202 is located directly above the vibrating screen 3. The vibrating screen 3 can be tilted by the first adjusting rod 4 below. The cooperation between the fourth support 202 and the fourth adjusting rod 804 can ensure that the angle of the material conveying frame 2 is adapted to the vibrating screen 3.

[0027] Furthermore, a support and adjustment mechanism is installed below the vibrating screen 3. This mechanism supports and adjusts the material discharge frame 5. The fifth adjustment rod 13 in the support and adjustment mechanism is installed between the material discharge frame 5 and the vibrating screen 3. The end of the material discharge frame 5 is hinged to the moving frame 1. By changing the length of the fifth adjustment rod, the distance between the material discharge frame 5 and the bottom of the vibrating screen 3 is changed, so that the two are stacked more compactly when folded. In addition, the structure of the material discharge frame 5 can also be the same as that of the material conveying frame 2. The material discharge frame 5 consists of two parts: the fifth support 501 and the sixth support 502. The sixth support 502 is hinged to the front end of the fifth support 501. The sixth adjustment rod 503 is located below the fifth support 501 and the sixth support 502. After the sixth adjustment rod 503 extends, it drives the sixth support 502 to rotate upward. The sixth support 502 rotates counterclockwise, thereby reducing the span of the device and facilitating its movement through bends.

[0028] In this application, the screening and conveying frame 2, the screening and discharging frame 5, the first folding frame 8, the second folding frame 10 and the third folding frame 12 all have complete transmission belt structures, and have head and tail cleaners at the ends. Furthermore, they are surrounded by protective covers and dust suppression devices that protect the transmission belts. The above structures are technical features that can be easily obtained by those skilled in the art, and will not be described in detail here.

[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.
