Description

Technical Field

[0001] This invention belongs to the field of crushing equipment technology, specifically a gangue crushing and processing device. Background Technology

[0002] Green mining and mineral processing employ environmentally friendly, sustainable, and efficient methods to minimize negative environmental impacts. When processing gangue, the most useful components are recovered and reused as much as possible to reduce resource waste. Existing methods for crushing gangue before processing often use crushers to break it into smaller particles. However, even with strip-shaped gangue, the crushed particles remain uneven in size, resulting in larger overall crushed stones. This necessitates more frequent processing of larger stones in subsequent crushing operations, severely impacting machine lifespan and productivity. Therefore, it is necessary to provide a gangue crushing and processing device to address the problems mentioned in the background. Summary of the Invention

[0006] Furthermore, as a preferred embodiment, the baffle is evenly distributed with multiple adapter ports, and the side wall of the main transfer wheel is provided with multiple annular grooves. Each steel tooth of the biting tooth group cuts into the main transfer wheel through the adapter port and the annular groove.

[0022] Please see Figures 1-8 In this embodiment of the invention, a gangue crushing and processing device includes: a steel frame base 1, on which a lower processing box 2 is mounted. A crushing mechanism is disposed within the lower processing box 2. A transmission shaft 12 is rotatably connected to one side of the lower processing box 2. One end of the transmission shaft 12 is connected to the crushing mechanism for driving the crushing mechanism to crush the gangue. A drive motor 13 is vertically mounted on the steel frame base 1. The drive motor 13 is connected to the transmission shaft 12 via gear meshing. A machine base 3 is connected above the lower processing box 2. The machine base 3 is equipped with a feed inlet, and a support bucket 31 is fixed at the feed inlet. A cutting mechanism 4 is installed inside the machine base 3. The cutting mechanism 4 is used to structurally bite the strip-shaped gangue, so that multiple fractures are formed on the strip-shaped gangue. A crushing component 5 is also installed at the discharge end of the cutting mechanism inside the machine base 3. That is, the cutting mechanism can pre-treat the strip-shaped gangue, so that the strip-shaped gangue can be structurally broken when it enters the crushing and pulverizing stage, avoiding jamming. Even if the strip-shaped gangue fails to break during the crushing process, it can still improve the crushing effect of the strip-shaped gangue when it enters the pulverizing stage.

[0023] In this embodiment, the cutting mechanism 4 includes: an inner channel 41 disposed within a base 3; two guide rollers 42 rotatably disposed within the base 3, the guide rollers 42 rotating outwards in opposite directions; the lower end of the inner channel 41 disposed on one side above the guide rollers 42; a main transfer wheel 43 rotatably disposed within the base 3 on the other side of the guide rollers 42; and a drive unit 45 mounted outside the base 3, the drive unit 45 being connected to the main transfer wheel 43 via a transmission chain for transmission. Multiple transfer ports are evenly distributed around the circumference of the main transfer wheel 43. These transfer ports can transfer gangue one by one. A baffle 44 is fixed inside the base 3 on one side of the main transfer wheel 43. The cross-section of the baffle 44 is arc-shaped. A toothed assembly 46 is also rotatably arranged inside the base 3 above the main transfer wheel 43. The gangue is quickly cut and crushed by the toothed assembly in the transfer ports, thus forming a fracture. It should be noted that the toothed assembly rotates in the same direction as the main transfer wheel, but its rotational speed is much greater than that of the main transfer wheel.

[0024] In a preferred embodiment, the guide rollers 42 are all inclinedly mounted inside the base 3, and the side of them closest to the main transfer wheel 43 is set to a low position. When the transfer port on the main transfer wheel 43 is close to the guide roller 42, the transfer port can be connected to the guide gap between the guide rollers 42. When the transfer port and the guide gap are misaligned, the main transfer wheel 43 can form a block on the guide gap. Thus, the gangue accumulated during the rotation of the guide rollers can be arranged one by one through the guide gap and transported to the low position, and enter the transfer port of each main transfer wheel. At this time, the strip-shaped gangue is laid flat.

[0025] In this embodiment, the baffle 44 has a plurality of fitting ports 441 evenly distributed on it, and the side wall of the main transfer wheel 43 is provided with a plurality of annular grooves. Each steel tooth of the toothing group 46 passes through the fitting port 441 and cuts into the main transfer wheel 43 through the annular groove. The cutting depth of the steel teeth is between 3mm and 6mm, and the spacing between each steel tooth is less than 25mm.

[0026] In this embodiment, metal push plates 431 are symmetrically rotated on the main transfer wheel 43 within each transfer port. A telescopic guide rod 432 is embedded and hinged inside the main transfer wheel 43. The telescopic end of the telescopic guide rod 432 is hinged to the metal push plate 431. In particular, the metal push plate pushes the thick and wide sides of the strip-shaped gangue outward during the pushing process, and the baffle prevents material from falling during the pretreatment.

[0027] In this embodiment, the crushing component 5 includes: a movable jaw plate 51, which is eccentrically rotatably mounted on a main shaft. The main shaft is rotatably mounted inside a machine base 3 and located on one side of the cutting mechanism 4. A fixed jaw plate 52 is obliquely fixed inside the machine base 3. The movable jaw plate 51 and the fixed jaw plate 52 are mounted in an inverted V-shape. A movable jaw hydraulic cylinder is connected to the machine base 3. One end of the movable jaw hydraulic cylinder is connected to the movable jaw plate 51 (all of the above are prior art and will not be described in detail here). A toothed plate 6 is installed at the lower end of the movable jaw plate 51.

[0028] In a preferred embodiment, a guide shaft 61 is fixed on the movable jaw plate 51, the toothed plate 6 is slidably connected to the guide shaft 61, a spring is connected between the toothed plate 6 and the guide shaft 61, and a plurality of linear oscillators 62 are provided between the toothed plate 6 and the movable jaw plate 51.

[0029] In this embodiment, the fixed jaw plate 52 is provided with a rubbing tooth opening, and the toothed plate 6 can be staggered with the rubbing tooth opening, so that the strip-shaped gangue is completely crushed by the pressure of the toothed plate on the fracture surface. In particular, the linear oscillator realizes the horizontal high-frequency displacement of the toothed plate under continuous operation. When the movable jaw plate cooperates with the fixed jaw plate to destroy the strip-shaped gangue, the toothed plate squeezes the crushed gangue in the rubbing tooth opening at high frequency under the horizontal high-frequency displacement, so that the gangue that is not completely crushed breaks through the structure corresponding to the fracture surface.

[0030] Specifically, after screening, the difficult-to-process strip-shaped gangue can enter the machine base. At this time, the guide rollers, in coordination with the rotation, transport it one by one to the transfer port of the main transfer wheel. The steel teeth of the biting tooth group form a structural bite on the strip-shaped gangue through the matching port, so that multiple fractures are formed on the strip-shaped gangue, thereby achieving the pretreatment of the gangue. Then it enters the crushing stage. On the one hand, the strip-shaped gangue is initially crushed under the pressure of the movable jaw plate. On the other hand, the crushed gangue in the toothed mouth is subjected to lateral pressure from the tooth plate, and is broken through the corresponding structure of the fracture as much as possible. Even if the strip-shaped gangue does not break during the crushing process, the crushing effect of the strip-shaped gangue can be improved under the influence of the fracture when it enters the pulverizing stage.

[0031] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
