The two side conveyors 2 are mounted on the fixed frame 7 and are respectively connected to the fixed frame 7. The two side conveyors 2 and the fixed frame 7 are detachable. The finished product conveyor 9 is located at the other end of the modular frame 5. The finished product conveyor 9 is connected to the modular frame 5 and is detachable. The feeding end of the finished product conveyor 9 is located below the discharging end of the screen bottom conveyor 1. One end of the finished product conveyor 9 is connected to the fixed frame 7 through the connecting frame 8. The finished product conveyor 9 and the connecting frame 8, and the connecting frame 8 and the fixed frame 7 are detachable, which facilitates assembly and subsequent maintenance and management of the equipment. The detachable components are connected by bolts or quick-release pins to form a complete integrated screening system, allowing for convenient transport in a single vehicle. In this invention, materials are conveyed from the top conveyor 6 to the horizontal screening machine 4. After screening by the horizontal screening machine 4, the materials exit through the distribution hopper assembly 3 and the bottom, and finally are transported out by various conveyors. This results in high screening efficiency.

[0033] like Figure 2As shown, the modular frame 5 includes a main beam frame 51, a work platform 52, ladders 53, and guardrails 54. The work platform 52 is located on the side of the top of the main beam frame 51, which serves as a support and connection. The guardrails 54 are located on the outside of the work platform 52, providing safety protection. Ladders 53 are located on both sides of one end of the main beam frame 51 and are connected to the work platform 52. The work platform 52 has a U-shaped structure, allowing workers to perform detailed inspections and management of the equipment. Workers can access the work platform 52 via the ladders 53 to inspect, repair, and manage the equipment. The modular frame mainly consists of interconnected main beam frames, work platforms, ladders, and guardrails. It features a lightweight structure, facilitates hoisting, and can be expanded to assemble more integrated equipment.

[0034] like Figures 3-4 As shown, the horizontal screening machine 4 includes a support base 41, a screen box 42, an upper screen 43, a lower screen 44, a screening motor 45, and a vibrator 46. The support base 41 is connected to the main beam frame 51, and the support base 41 and the main beam frame 51 are detachable. The screen box 42 is mounted on the support base 41 and connected to the support base 41. The upper screen 43 and the lower screen 44 are respectively mounted on the screen box 42, with the lower screen 44 positioned below the upper screen 43. The discharge ports of the material on the upper screen and the material on the lower screen 44 are located at the same end. The upper screen 43 and the lower screen 44 are detachably connected to the screen box 42. Screens with different mesh sizes can be replaced or new screens can be replaced as needed. The screening motor 45 is located on one side of the screen box 42. The vibrator 46 is connected to the screening motor 45 via a belt 47. The two sides of the screen box 42 are connected to the support base 41 via spring damping devices 48. A feed plate device 49 is provided at one end of the screen box 42. The vibrator is connected to the screen box via a sealing plate. The vibrator features a three-axis drive, ensuring continuous screening capacity and large amplitude under material impact. The vibrator includes a main shaft 461, bearing housing and bearing 462, sealing device 463, pulley 464, linkage flywheel (gear) 465, and eccentric block 466. The pulley 464 is connected to the screening motor 45 via a belt 47. When the screening motor starts, the belt drive rotates the vibrator's pulley, which in turn rotates the main shaft and flywheel. The rotation of the eccentric block generates excitation force, which, separated by springs, causes the screen box to vibrate reciprocally. The support base is then fixedly mounted on the frame. The upper screen 43 and lower screen 44 of the horizontal screening machine 4 can screen materials into three different specifications. The vibrating motor drives the vibrator to generate directional vibration, causing the material to jump linearly on the screen surface, thus achieving grading and screening.

[0035] like Figures 5-7As shown, the material distribution hopper assembly 3 includes a material distribution hopper 31, a rotary device 32, and a manual wrench 33. The rotary device 32 is located on one side of the material distribution hopper 31, and the manual wrench 33 is located on the rotary device 32. The inlet of the material distribution hopper 31 is connected to the outlet of the horizontal screening machine 4, and the material distribution hopper 31 is connected to the fixed frame 7. The hopper 31 is provided with a first discharge port 34 and a second discharge port 35. A tilting plate 36 is provided between the first discharge port 34 and the second discharge port 35. The tilting plate 36 is movably mounted on the hopper 31 and is connected to a rotating device 32. The rotating device 32 is existing technology. The tilting plate 36 separates the discharge ports at the same end of the upper screen 43 and the lower screen 44, so that the discharge port of the upper screen 43 is connected to the second discharge port 35, and the discharge port of the lower screen 44 is connected to the first discharge port 34. The first discharge port 34 is connected to the discharge port of the upper screen 43, and the second discharge port 35 is connected to the discharge port of the lower screen 44. The side conveyors 2 are respectively located below the first discharge port 34 and the second discharge port 35 for conveying materials. The material distribution hopper assembly consists of a material distribution hopper, a manual wrench, a rotating device, and a rotating plate. The opening and closing of the material distribution plate can be directly switched manually, indirectly affecting whether the two materials at the screening machine are combined or separated. The rotating device consists of a rotating shaft, bearings, and an outer ring fixing sleeve. During use, if two different material specifications are required, the operator can operate the manual wrench 33, which, through the rotating device 32, rotates the tilting plate 36 towards the second discharge port 35, sealing it. This allows the material on the upper screen 43 and the lower screen 44 to be combined and discharged from the first discharge port 34. The double-layer screens can separate three different material specifications. The material distribution hopper assembly allows for the selection of combining the first and second layers of material, and the selection of two materials for screening. Without disassembling the screens, this provides more screening options on-site, enabling switching between dual-material and triple-material output mechanical structures.

[0036] like Figure 1 and Figure 8 As shown, the screen bottom conveyor 1 is connected to the modular frame 5. The screen bottom conveyor 1 is equipped with a screen bottom feed hopper 11, which is located below the discharge port at the bottom of the horizontal screening machine 4. The material undersized from the lower screen 44 exits from the bottom of the horizontal screening machine 4 and enters the screen bottom feed hopper 11 of the screen bottom conveyor 1, where it is then conveyed out.

[0037] like Figure 1 and Figure 9As shown, the screen top conveyor 6 is connected to a support base 61, which is connected to a fixed frame 7. A feed hopper is provided at the feeding end of the screen top conveyor 6 to prevent material overflow. The material is fed from the feeding end of the screen top conveyor 6 and transported to the horizontal screening machine 4 for screening via the screen top conveyor 6.

[0038] like Figure 1 and Figure 10 As shown, the finished product conveyor 9 is equipped with a finished product feed hopper 91 at its loading end, and the finished product feed hopper 91 is located below the unloading end of the screen bottom conveyor 1. The material coming out of the screen bottom conveyor 1 enters the finished product feed hopper 91 of the finished product conveyor 9, and is then conveyed out by the finished product conveyor 9.

[0039] like Figure 1 and Figure 11 As shown, the side conveyor 2 is connected to the fixed frame 7, and an overflow baffle 21 is provided on the side conveyor 2 to prevent material from overflowing. The material coming out of the distribution hopper 31 is conveyed out through the side conveyor 2. The screen bottom conveyor, screen top conveyor, finished product conveyor, and side conveyor are all existing technologies, consisting of a conveyor belt, drive roller, driven roller, conveyor frame, upper idler roller, lower idler roller, baffle idler roller, tensioning device, cleaner, feed hopper, and protective device.

[0040] Working principle

[0041] The material is conveyed by the top conveyor 6 to the feed plate device 49 of the horizontal screening machine 4. After being screened by the horizontal screening machine 4, the material is discharged through the distribution hopper assembly 3 and the bottom. The material exiting through the distribution hopper assembly 3 is conveyed out by two side conveyors 2, and the material at the bottom of the horizontal screening machine 4 is conveyed out by the finished product conveyor 9. When it is necessary to screen two kinds of materials, the manual wrench 33 on the manual distribution hopper assembly 3 rotates the tilting plate 36 to one side of the second discharge port 35 through the rotary device 32 and blocks the second discharge port 35, so that the material on the upper screen 43 and the material on the lower screen 44 both exit from the first discharge port 34 and are then conveyed out by the side conveyors 2, realizing the mechanical structure switching between dual-material and triple-material output.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
