Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to an impact crusher track station. Background Technology

[0002] Crushing equipment is a core component in industries such as mining, construction waste treatment, and aggregate production. For a long time, stationary crushers have dominated, with typical examples including jaw crushers, cone crushers, and traditional impact crushers. While these types of equipment exhibit stable crushing performance in specific scenarios, they suffer from significant structural defects that severely restrict the efficiency and flexibility of modern engineering operations.

[0003] Stationary crushers require pre-cast concrete foundations, involving complex processes such as geological exploration, foundation design, rebar tying, concrete pouring, and curing. For example, in a large limestone mine project, the construction period for its jaw crusher foundation was as long as 21 days, requiring the use of large equipment such as excavators and concrete pump trucks, with direct costs exceeding 500,000 yuan. Even more challenging is the need to relocate equipment when production demands change or mineral resources are depleted. This requires reverse demolition of the foundation, cutting of the steel structure, and hoisting and transport, with a single relocation costing 2-3 million yuan and taking 7-10 days, resulting in significant losses due to production line downtime.

[0004] In addition to the challenges of relocating individual machines, the serial layout of traditional crushing-screening systems further exacerbates production bottlenecks. The core problem lies in the inefficiency and unreliability of material transfer. A typical crushing-screening system consists of 5-7 pieces of equipment, including a feeder, crusher, vibrating screen, conveyor belt, and loader. The material needs to be transferred multiple times to complete crushing and screening. Any problem with any link in the external transfer equipment will restrict the overall production capacity.

[0027] 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. Example 1

[0028] Please see the appendix Figure 1-6This embodiment describes an impact crusher tracked station, comprising a mobile frame 1, a vibrating hopper 2, a pre-selection screen 3 fixedly connected inside the vibrating hopper 2, a first conveyor belt 4 below the pre-selection screen 3, a crushing box 5 connected to the side of the pre-selection screen 3, a wear-resistant rotor 6 rotatably connected inside the crushing box 5, an impact component 7 on the side of the wear-resistant rotor 6, a bottom plate feeder 8 below the crushing box 5, and a second conveyor belt 9 connected to the side of the bottom plate feeder 8.

[0029] The mobile frame 1 is the main load-bearing structure of this equipment. The mobile frame 1 has a boat-shaped design with upward-curving arcs on both sides. The bottom of the mobile frame 1 has tracked wheels, which improve the flexibility of the equipment and facilitate subsequent relocation, eliminating the need for disassembly before towing and greatly reducing worker workload. The tracked wheels, unlike traditional tire wheels, can adapt to more complex road structures, improving the equipment's adaptability to harsh environments. The upper part of the mobile frame 1 supports the vibrating hopper 2, crushing box 5, material conveying system, hydraulic system, power system, and control system. The mobile frame 1 also has a maintenance platform, such as... Figure 1 As shown, the vibrating hopper 2 is located at the far left of the mobile frame 1. The vibrating hopper 2 has a downward-facing recessed groove. The stones to be crushed are transported into the vibrating hopper 2 by the loader. The bottom of the vibrating hopper 2 is a pre-screening screen 3. The screen openings on the pre-screening screen 3 are smaller than the size of the finished stones. The pre-screening screen 3 is used to remove soil from the stones, improving the purity of the subsequent finished stones and reducing dust pollution during crushing. The soil passing through the screen openings of the pre-screening screen 3 falls onto the first conveyor belt 4 under gravity and is then transported by the first conveyor belt 4 to the rear of the frame. Meanwhile, the stones above the pre-screening screen 3... The stones enter the inner cavity of the crushing box 5, where a rotating wear-resistant rotor 6 is installed. The wear-resistant rotor 6 is evenly equipped with crushing blades, and the side of the wear-resistant rotor 6 is an impact assembly 7. The wear-resistant rotor 6 rotates in the direction of the impact assembly 7, crushing the large stones into small stones through compression and cutting. The crushed small stones fall through the gap between the wear-resistant rotor 6 and the impact assembly 7 onto the floor feeder. The floor feeder transfers the small stones to the second conveyor belt 9, which is inclined upwards. The loading vehicle can move to the right side of the second conveyor belt 9 to collect the stones.

[0030] The impact assembly 7 includes a first impact frame 701 and a second impact frame 702. Both the first impact frame 701 and the second impact frame 702 are hinged to the crushing box 5. The first impact frame 701 is located diagonally above the second impact frame 702. A hydraulic rod 703 is hinged to the first impact frame 701, and the other end of the hydraulic rod 703 is hinged to the crushing box 5. A buffer rod 704 is hinged to the second impact frame 702, and the other end of the buffer rod 704 is hinged to the crushing box 5.

[0031] Furthermore, in this application, the counterattack assembly 7 is composed of a first counterattack frame 701 and a second counterattack frame 702, as shown below. Figure 5 and Figure 6 As shown, the first impact frame 701 is located near the feed inlet of the crushing box 5, and is further away from the wear-resistant rotor 6. Both the first impact frame 701 and the second impact frame 702 are hinged to the crushing box 5 at their upper ends. The first impact frame 701 and the second impact frame 702 have an arc-shaped profile. During the clockwise rotation of the wear-resistant rotor 6, the wear-resistant rotor 6 crushes the stones in stages, avoiding excessive crushing resistance and protecting the crushing blades. In addition, the lower end of the first impact frame 701 is supported by a hydraulic rod 703, which is controlled by the hydraulic system. When the length of the hydraulic rod 703 changes, the distance between the first impact frame 701 and the wear-resistant rotor 6 also changes, thereby adjusting the crushing of the stones. The size of the stone is determined by the rear end of the second impact frame 702, which is connected by a buffer rod 704. The buffer rod 704 consists of two sliding support rods and a spring. Under the action of the spring, the buffer rod 704 is initially in its longest position, at which time the distance between the wear-resistant rotor 6 and the second impact frame 702 is the smallest. When breaking stones, the stones exert a counterforce on the wear-resistant rotor 6 and the second impact frame 702. When the counterforce is too large, the second impact frame 702 will compress the spring on the buffer rod 704, causing the second impact frame 702 to move to the right, increasing the distance between the second impact frame 702 and the wear-resistant rotor 6. This prevents the wear-resistant rotor 6 from jamming due to excessive resistance and avoids damage to the motor due to excessive load.

[0032] The vibrating hopper 2 is connected to the mobile frame 1 via an elastic buffer 10. The vibrating frame is driven by a vibrating motor, and the elastic buffer 10 provides high-frequency vibration, similar to existing vibrating frames, improving material feeding efficiency and preventing jamming. Furthermore, the vibrating hopper 2 has folding baffles hinged to its front, rear, and right sides. These baffles are hydraulically controlled; when in use, they are opened to increase the depth of the hopper and expand its storage capacity. When not in use, the baffles can be folded back onto the vibrating hopper 2, without increasing the overall height of the device, facilitating transportation.

[0033] The first conveyor belt 4 has the same structure as the existing conveyor belt. The first conveyor belt 4 is mounted on the first material rack 11, which is mounted on the rear side of the moving frame 1. The upper middle part of the first material rack 11 is hinged to the moving frame 1 via a connecting shaft. The first material rack 11 can rotate back and forth. Figure 2As shown, the first adjusting rod 12 is a hydraulic rod 703. The first adjusting rod 12 is controlled by the hydraulic system. When the length of the first adjusting rod 12 is extended, the first adjusting rod 12 drives the first material rack 11 to rotate upward, so that the first material rack 11 is attached to the rear side of the moving frame 1, reducing the overall front and rear width of the equipment and facilitating subsequent transportation.

[0034] A vibrating motor is connected to the bottom plate feeder 8, which provides a power source for the vibrating guide plate 801. The buffer spring 802 is located below the right side of the vibrating guide plate 801. The vibrating guide plate 801 is placed at an angle, so that the crushed stones can slide to the right better under the action of gravity. The right side of the vibrating guide plate 801 is slightly higher than the second conveyor belt 9, ensuring that the stones can fall onto the second conveyor belt 9.

[0035] Furthermore, the second conveyor belt 9 is supported by the second material rack 13, which has the same structure as the first material rack 11. The second material rack 13 also has a motor and drive rollers to drive the movement of the second conveyor belt 9. The second material rack 13 is also connected to a support rod 14, which is located above the second conveyor belt 9. The support rod 14 is equipped with a support platform 15, and the center of the support platform 15 is a strong magnetic block. The strong magnetic block attracts stones with a high iron content on the second conveyor belt 9. Furthermore, in order to maintain the maximum magnetic force of the strong magnetic block on the second conveyor belt 9, one end of the support platform 15 is hinged to the support rod 14, and the other end is adjusted by an adjustment component to adjust its tilt angle, thereby improving the ability of the support platform 15 and the second conveyor belt 9 to work together.

[0036] Furthermore, drive rollers are installed on both the front and rear sides of the strong magnetic block, and iron removal belt 16 is wound on the drive rollers. The length of the strong magnetic block is less than the length of the iron removal belt 16. When the iron removal belt 16 brings the iron-containing stone to one side of the strong magnetic block, the iron-containing stone is thrown to one side under the action of inertia and gravity. Example 2

[0037] Similar to the structure of the above embodiment, as shown in the figure, the specific difference in this embodiment is that: a screening frame 17 is hinged to the bottom of the second material rack 13, a second adjusting rod 18 is installed between the middle of the screening frame 17 and the second material rack 13, the screening frame 17 includes a finished product screen 1701, a third conveyor belt 1702 is provided below the finished product screen 1701, a third material rack 1703 is provided on the side of the finished product screen 1701, the third material rack 1703 is hinged to the screening frame 17, and a fourth conveyor belt 1704 is provided on the third material rack 1703.

[0038] In this implementation, a screening frame 17 is installed below the second material rack 13. The screening frame 17 is mainly used to screen the finished stone. The upward extension of the screening frame 17 is greater than that of the second material rack 13. Therefore, after the stones on the second conveyor belt 9 are detached from above, they enter the finished screen 1701 under the action of gravity. The finished screen 1701 has screen holes. Stones that meet the size requirements fall through the screen holes to the third conveyor belt 1702 and move to the right by the third conveyor belt 1702. Meanwhile, the larger stones above the finished screen 1701 are transferred again to the vibrating hopper 2 through the third material rack 1703 and the fourth conveyor belt 1704. The third material rack 1703 has two transverse connecting platforms at both ends. At the same time, the third material rack 1703 has an angle adjustment function and has a degree of freedom of rotation between itself and the two transverse connecting platforms, which can move large stones to other positions.

[0039] The screening frame 17 is hinged to the second frame 13. The tilt angle of the screening frame 17 is adjusted by the second adjusting rod 18, which works on the same principle as the first adjusting rod 12.

[0040] 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.
