[0024] Please see Figure 1-8 One embodiment provided by this utility model:

[0025] A multi-purpose heavy-duty screening station includes a tracked chassis 8, a main frame 7 fixedly mounted on the surface of the tracked chassis 8, a screen frame assembly 12 on the surface of the main frame 7, the screen frame assembly 12 including a screen box 2, a secondary frame 9, and an under-screen transition conveyor 13, the secondary frame 9 being fixedly connected to the bottom of the screen box 2, the under-screen transition conveyor 13 being located at the bottom of the screen box 2, multiple sets of three discharge ports and one inlet port being provided on the surface of the screen box 2, a large material conveyor 3 being rotatably mounted on one of the discharge ports of the screen box 2, and a medium material conveyor 4 being rotatably mounted on one of the discharge ports of the screen box 2. A set of discharge ports is rotatably equipped with a fine material conveyor 5. A chain plate feeder 1 is installed at one end of the inlet of the screen box 2. A power and hydraulic system 6 is fixedly installed on the surface of the chain plate feeder 1. The screen box 2 is fixedly installed at the bottom. A connecting rod 10 is rotatably connected to the surface of the main frame 7. The end of the connecting rod 10 away from the main frame 7 is rotatably connected to the auxiliary frame 9. A cylinder body 11 is rotatably connected to the surface of the connecting rod 10. A front support assembly 14 is rotatably connected to the surface of the main frame 7. The end of the front support assembly 14 away from the main frame 7 is rotatably connected to the auxiliary frame 9.

[0026] Furthermore, a left wall panel assembly 21 and a right wall panel assembly 22 are fixedly installed on both sides of the screen box 2, a spring support 23 is fixedly installed on the side wall of the screen box 2, a main shaft excitation assembly 24 is fixedly installed inside the screen box 2, a screen tensioning seat 25 is fixedly installed on the surface of the screen box 2, a frame main beam 26 is provided at the bottom of the screen box 2, a first layer of screen plate base frame 27 is fixedly installed inside the screen box 2, a second layer of screen frame 28 is fixedly installed inside the screen box 2, a second layer of screen mesh 29 is fixedly installed inside the chain plate feeder 1, a receiving rubber plate 31 is fixedly installed at the bottom of the screen box 2, a screen tensioning plate 32 is fixedly installed on the surface of the screen tensioning seat 25, and a slot pull plate 33 is installed on the surface of the screen tensioning plate 32. One side of the plate 33 is threaded with a tension bolt 34. The structural design of the screen box 2 is intended to provide a stable screening platform. The left wall plate assembly 21 and the right wall plate assembly 22 serve as side walls, enhancing the stability of the screen box 2. The spring support 23 is used for shock absorption, reducing the impact of vibration on the screen box 2. The main shaft excitation assembly 24 provides a vibration source, promoting the screening process. The screen tensioning seat 25 and the screen tensioning plate 32 are used to fix and adjust the screen, ensuring the screening effect. The frame main beam 26 and the first-layer screen plate base 27 enhance the load-bearing capacity of the screen box 2. The second-layer screen frame 28 and the second-layer screen 29 are used for fine screening. The receiving rubber plate 31 collects the screened material. The slot pull plate 33 and the tension bolt 34 are used to adjust the tightness of the screen.

[0027] Furthermore, an arc-shaped slot is provided on the surface of the main frame 7. The screen frame assembly 12 will be lowered into the arc-shaped slot of the main frame 7. The arc-shaped slot design on the main frame 7 allows the screen frame assembly 12 to be lowered when not needed, which facilitates maintenance and screen replacement.

[0028] Furthermore, a hydraulic cylinder is provided on the surface of the front support assembly 14, and an angle positioning hole is designed on the inner tube of the support of the front support assembly 14. The piston rod of the cylinder body 11 is rotatably connected to the surface of the connecting rod 10. The cylinder body 11 drives the connecting rod 10 to rotate on the main frame 7 through the piston rod. The hydraulic cylinder and angle positioning hole design on the front support assembly 14 allow adjustment of the tilt angle of the screen box 2 to facilitate the screening and conveying of materials.

[0029] Furthermore, the screen tensioning seat 25 is provided with an elongated groove, and the screen tensioning plate 32 is inserted into the elongated groove of the cylinder body 11. The elongated groove design allows the screen tensioning plate 32 to slide on the screen tensioning seat 25, which facilitates the adjustment of the screen tension and ensures the convenience of screen adjustment.

[0030] Furthermore, the surface of the slot pull plate 33 is provided with hook grooves, and the hook grooves are engaged with both ends of the cylinder body 11. One end of the second-layer screen 29 is hooked onto the second-layer screen frame 28, and the other end is hooked onto the screen tension plate 32. The hook groove design on the slot pull plate 33 allows the slot pull plate 33 to be engaged with both ends of the cylinder body 11 to fix the position of the screen tension plate 32.

[0031] Furthermore, the screen installation structure of the second-layer screen frame 28 is designed as an arc-shaped stepped segmented structure. The arc-shaped stepped segmented design is conducive to the uniform and rapid spreading of materials during the vibrating screening process, thereby improving the screening effect.

[0032] Working principle: Material enters the screen box 2 via a chain plate feeder 1. The main shaft vibration assembly 24 provides the vibration source, causing the material to be screened on the screen surface. This allows materials of different particle sizes to be separated through screens of different apertures. Larger particles are output through the large material conveyor 3, medium-sized particles through the medium material conveyor 4, and smaller particles through the fine material conveyor 5. The screen tensioning seat 25 and the screen tensioning plate 32 ensure that the screen remains tight during vibration, improving screening efficiency. When replacing the screen or maintaining the screen box 2, the cylinder body 11 drives the connecting rod 10 to rotate through the piston rod. The connecting rod 10 lifts the screen frame assembly 12, allowing the operator to easily enter the screen box 2 from the bottom for maintenance. The elongated groove on the screen tensioning seat 25 allows the screen tensioning plate 32 to slide within it, facilitating the adjustment of the screen tension. The hook groove on the slot pull plate 33 engages with both ends of the cylinder body 11, ensuring that the position of the screen tensioning plate 32 is fixed. One end of the second-layer screen 29 is hooked onto the second-layer screen frame 28, and the other end is hooked onto the screen tensioning plate 32, facilitating replacement and fixation.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
