Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a dual-combination tire station for jaw crusher and impact crusher. Background Technology

[0002] In fields such as construction, mining, and highway construction, material crushing is a crucial process in production. To obtain final products with different particle sizes and shapes, multi-stage crushing processes are typically required. Among these, jaw crushers and impact crushers are two of the most common crushing equipment, each with its own advantages.

[0003] Jaw crushers are known for their robust structure and powerful crushing force, using the squeezing action between the moving and stationary jaws to crush materials. They are particularly suitable for primary or secondary crushing of large, high-hardness stones, with a large feed opening that can easily handle raw, large stones extracted from mines. However, the crushed products tend to have poor particle shape, mostly needle-like or flaky, and often contain a certain proportion of long strips or large pieces that do not meet the target particle size requirements.

[0004] Impact crushers utilize a high-speed rotating rotor to impact materials, causing them to break down through repeated impacts between the impact plates and the rotor. Their advantages include excellent crushing efficiency (more crushing, less grinding), high production efficiency, and well-shaped finished materials, mostly cubic, making them ideal for construction aggregates. Therefore, they are often used as secondary or tertiary medium-fine crushing equipment. However, their structure limits their capacity to handle large pieces of material entering their chambers, and their relatively weak abrasion resistance makes them unsuitable for direct primary crushing.

[0005] Currently, in small- to medium-scale operations or temporary projects requiring frequent site relocation, the common practice is to use separate jaw crusher and impact crusher plants. The workflow is as follows: first, the large stones extracted are fed into the jaw crusher for initial crushing; after the jaw crusher completes one batch of operations, the semi-finished stones from the jaw crusher outlet are transferred to the impact crusher inlet using auxiliary equipment such as loaders and dump trucks, as well as a large amount of manual operation, for the second stage of fine crushing.

[0006] This traditional separate-combination method has the following significant drawbacks: 1. Discontinuous operation and low efficiency: The two crushing units operate independently, and the transfer of material between them is a discontinuous and intermittent process. When the jaw crusher is crushing, the impact crusher is waiting; during material transfer, both machines may be stopped or operating inefficiently. This "discontinuous" process severely restricts the continuous output capacity of the entire production line, resulting in low overall efficiency.

[0007] 2. High labor and equipment costs, and complex operation processes: Material transfer relies entirely on additional transportation equipment and manual operation, which not only increases fuel consumption and rental costs for equipment such as loaders, but also increases the labor intensity and safety hazards for operators. The entire process involves many steps and is complex to manage.

[0008] 3. Poor site adaptability and insufficient flexibility: For construction projects that require frequent relocation (such as different sections of highway construction), repeatedly disassembling, installing, and positioning two independent pieces of equipment will consume a lot of time and manpower, resulting in extremely low relocation efficiency and failing to meet the high mobility requirements of modern construction.

[0009] 4. Large footprint: Two independent pieces of equipment and the transfer channel between them require a larger work area, making deployment difficult on construction sites with limited space.

[0010] In summary, the existing technology that simply separates jaw crushers and impact crushers, while leveraging the respective technological advantages of each, suffers from serious deficiencies in system integration and operational processes, resulting in problems such as low production efficiency, high costs, and poor maneuverability. Utility Model Content

[0011] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a dual-combination tire station for jaw crusher and impact crusher. This design effectively solves the serious defects in the system integration and operation process of existing crushing equipment, which leads to low production efficiency, high cost and poor mobility.

[0012] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a mobile frame, on which a hopper, a jaw crusher, an impact crusher, and a return vibrating screen are arranged sequentially from left to right. The material chamber of the jaw crusher is connected to the hopper. A material conveying component is provided below the jaw crusher and the impact crusher. The end of the material conveying component is located above the return vibrating screen. The return vibrating screen is provided with a return port and a discharge port. The return port is connected to the material chamber of the impact crusher. A discharge frame is provided at the discharge port.

[0013] Preferably, the material conveying assembly includes a first conveying belt, a dustproof discharge cylinder is fitted at the left end of the first conveying belt, a second conveying belt is fitted below the dustproof discharge cylinder, and a discharge platform is fitted at the other end of the second conveying belt.

Detailed Implementation

[0026] 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.

[0027] Please see the appendix Figure 1-6 This embodiment is a dual-combination tire station for jaw crusher and impact crusher: it includes a mobile frame 1, on which a hopper 2, a jaw crusher 3, an impact crusher 4 and a return vibrating screen 5 are integrated, and the units are seamlessly connected by a material conveying component 6 to form a continuous closed-circuit crushing production line.

[0028] At the heart of the tire station is a robust mobile frame 1. This frame serves as the foundation platform for the entire equipment, integrating all components into a single unit. From left to right, a hopper 2, a jaw crusher 3, an impact crusher 4, and a return vibrating screen 5 are fixedly mounted on the mobile frame 1. This compact, linear layout significantly reduces the total floor space occupied by the equipment and the internal material transfer distance.

[0029] To facilitate convenient relocation and movement, multiple sets of symmetrically distributed wheels 15 are rotatably connected to the bottom of the mobile frame 1. These wheels 15 are typically heavy-duty tires, allowing the entire equipment to be quickly towed to a new work location by a tractor. To ensure stability during operation, hydraulic outriggers 16 are provided around each set of wheels 15, with one end of each hydraulic outrigger 16 fixedly connected to the mobile frame 1. Upon reaching the work position, the hydraulic outriggers 16 are lowered via a hydraulic system, providing stable support to the ground and preventing swaying during operation.

[0030] During stone crushing: Large stones are first poured into hopper 2, which is directly connected to the feed chamber of jaw crusher 3. The material enters jaw crusher 3 under gravity, completing the first stage of coarse crushing. A conveying assembly 6 is connected to both jaw crusher 3 and impact crusher 4. This conveying assembly 6 automatically and continuously transports the primary crushed material discharged from the jaw crusher to the return vibrating screen 5. The return vibrating screen 5 screens the coarsely crushed stone; small particles pass through its upper screen plate and flow out from the discharge port 8, while large particles enter the impact crusher 4 from the return port 7 for secondary crushing. The crushed stone then falls back into the conveying assembly 6, which transports it again to the return vibrating screen 5 for further screening.

[0031] Furthermore, the material conveying assembly 6 specifically includes: a first conveyor belt 601 located directly below the discharge ports of the jaw crusher 3 and the impact crusher 4, with a dustproof discharge cylinder 602 fitted at its left end, which effectively suppresses dust emission. A second conveyor belt 603 is connected below the dustproof discharge cylinder 602, and a discharge platform 604 is fitted at the other end of the second conveyor belt 603. The discharge port of the discharge platform 604 is precisely located above the screen of the return vibrating screen 5.

[0032] The return vibrating screen 5 has three layers of screen plates inside for precise material classification. The uppermost screen has the largest openings to trap large particles that still require further crushing. These unqualified large particles roll off the screen surface and return directly to the feed chamber of the impact crusher 4 through the return port 7 on the screen body for secondary crushing. This forms a closed-loop circulation system of "impact crusher crushing - screening - large particle return", ensuring that all materials are crushed to below the target particle size.

[0033] After being graded by three layers of sieves, three discharge ports 8 are finally formed at the bottom of the return vibrating screen 5: the first discharge port 801, the second discharge port 802, and the third discharge port 803, corresponding to large, medium, and small finished aggregates, respectively. To efficiently collect and transfer these different sizes of finished aggregates, an independent discharge rack is configured at each discharge port 8: the first discharge port 801 is equipped with a first support 9; the second discharge port 802 is equipped with a second support 10; and the third discharge port 803 is equipped with a third support 11, which is placed parallel to the bottom of the return vibrating screen 5 to receive the finest materials. Belt conveyors 12 are rotatably connected to the first support 9, the second support 10, and the third support 11, which can transport the sorted finished aggregates to different stacking areas or transport vehicles, realizing automated sorting and storage of finished products.

[0034] To further optimize maneuverability during relocation, the first support 9 and the second support 10 are located on the front and rear sides of the mobile vehicle, respectively, and their inner sides are hinged to the mobile vehicle frame 1. Between the mobile vehicle frame 1 and the first support 9 or the second support 10, a first telescopic rod 13 (such as a hydraulic cylinder or electric push rod) is provided to control its pitch angle. During transport, the first telescopic rod 13 retracts, lifting the first support 9 and the second support 10 upwards, making them fit snugly against the sides of the vehicle frame, significantly reducing the transport width of the equipment.

[0035] Similarly, the left side of the return material vibrating screen 5 is hinged to the mobile frame 1 via a pivot, while the right side is hinged to a second telescopic rod 14, the other end of which is also hinged to the mobile frame 1. By controlling the extension and retraction of the second telescopic rod 14, the tilt angle of the return material vibrating screen 5 can be adjusted to change the screening efficiency, and it can also be adjusted to a more compact posture during relocation.

[0036] The overall working process of this utility model is as follows: During operation, large stones enter the jaw crusher 3 through the hopper 2 for coarse crushing. The coarsely crushed material is then conveyed to the return vibrating screen 5 for screening via the first conveyor belt 601, the dustproof discharge cylinder 602, the second conveyor belt 603, and the discharge platform 604. Finished products that meet the particle size requirements are separated from the first feed port 801, the second feed port 802, and the third feed port 803. Materials with excessively large particle sizes are returned to the impact crusher 4 through the return port 7 for fine crushing. The finely crushed material falls back into the conveying assembly 6 (via the first conveyor belt 601, the dustproof discharge cylinder 602, the second conveyor belt 603, and the discharge platform 604) for the next round of screening, forming a closed-loop cycle until all the material becomes a qualified finished product.

[0037] 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.
