[0054] Figure 1 This is a schematic diagram of the structure of a modular screening station according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 6 The embodiment of the present invention provides a modular screening station, comprising a main support frame 100, a vibrating screen 200, a plurality of discharge hoppers, an inspection platform 400, and a ladder assembly 500. The main support frame is an assembled frame. The vibrating screen 200 is arranged at an angle, and along the material conveying direction, the front end of the vibrating screen 200 is located below the rear end. The vibrating screen 200 is mounted on the upper side of the support frame. The plurality of discharge hoppers are configured to discharge the material screened by the vibrating screen 200. The inspection platform is arranged on the main support frame. The ladder assembly 500 cooperates with the inspection platform.

[0055] Material enters the vibrating screen 200 from above, is screened by the screen 220, and is discharged from the discharge hopper and conveyed to a designated location or the next module. The modular screening station, with fixed dimensions for the high-strength main support frame, discharge hopper, maintenance platform 400, and user-friendly ladder assembly 500, is based on the vibrating screen 200. This modular screening station, known as the MP (Modular Plant), standardizes the screening station and addresses shortcomings such as slow production delivery, high transportation costs, extensive on-site preparation, slow installation, and difficulty in relocation and component replacement.

[0056] In some embodiments of the present invention, a vibrating screen 200 includes an upwardly opening housing 210 and multiple layers of screens 220 disposed within the housing 210 and spaced apart along the height direction. The housing 210 is mounted above a main support frame. The multiple layers of screens 220 are arranged at an angle, with the front ends of the multiple layers of screens 220 positioned below the rear ends of the multiple layers of screens 220 in the material conveying direction. The material conveying direction is forward.

[0057] The material enters from the upward opening of the housing 210 and falls on the uppermost screen 220. The smaller material falls from the upper screen 220 and is screened by multiple layers of screens 220 with different apertures. The apertures of the multiple layers of screens gradually decrease from top to bottom.

[0058] In some embodiments of the present invention, Figure 1As shown, the discharge hopper includes an under-screen hopper 310 and a screen tail distributor 320. The inlet of the under-screen hopper 310 is opened on the lower wall of the shell 210, and the outlet of the under-screen hopper 310 faces downward. The under-screen hopper 310 is configured to discharge the material screened by the bottom screen 220. The screen tail distributor 320 includes a cavity and a plurality of discharge channels arranged in the cavity. The cavity has a plurality of feed ports and a plurality of discharge ports opening downward. The plurality of feed ports are respectively configured to receive the material screened by each layer of screen 220 corresponding to the upper side of the bottom screen 220, and the plurality of discharge ports opening downward are configured to discharge the material screened by each layer of screen 220 corresponding to the upper side of the bottom screen 220. The inlets of the plurality of discharge channels are respectively connected to the corresponding feed ports, and the outlets of the plurality of discharge channels are respectively connected to the corresponding discharge ports.

[0059] The multiple layers of screen 220 correspond to multiple discharge channels. Material falling onto each layer of screen 220 passes through the corresponding inlet, through the discharge channel, and out the corresponding outlet. Material leaking from the lowest screen 220 enters the inlet of the under-screen hopper 310 and is discharged through the outlet of the under-screen hopper 310. The outlet of the tail screen distributor 320 and the outlet of the under-screen hopper 310 both face downward, allowing the material to fall onto the conveyor belt and then be transported to different locations.

[0060] In some embodiments of the present invention, Figure 1 As shown, the main support frame includes a load-bearing sled 110, two first legs 120, two second legs 130, and an upper frame. The load-bearing sled 110 includes two parallel, spaced-apart load-bearing columns, each horizontally arranged. Along the direction of material movement, the two first legs 120 are located in front of the two second legs 130. The two first legs 120 are perpendicular to the two load-bearing columns, with the lower end of each first leg 120 connected to a corresponding load-bearing column. The two second legs 130 are also perpendicular to the two load-bearing columns, with the lower end of each second leg 130 connected to a corresponding load-bearing column. The height of the two first legs 120 is less than that of the two second legs 130. The upper frame is a modular frame with a rectangular structure. It is located above the two load-bearing columns. The upper ends of the two first legs 120 are connected to two corners of the upper frame. The upper ends of the two second legs 130 are connected to the other two corners of the upper frame.

[0061] The load-bearing columns are directly on the ground, and are in the same direction as the material transportation direction. The two first legs 120 and the two second legs 130 connect the two load-bearing columns and the upper frame, providing support. The two first legs 120 are in the same plane, and this plane is perpendicular to both load-bearing columns. The two second legs 130 are in the same plane, and this plane is perpendicular to both load-bearing columns. The upper frame is connected to the upper ends of the two first legs 120 and the two second legs 130, and the upper frame is also tilted.

[0062] In some embodiments of the present invention, Figure 4 As shown, the load-bearing column includes two flat plates spaced apart from each other, a connecting plate, and multiple reinforcing plates 111.

The rear support beam 180 is horizontally arranged and extends forward and backward along the material conveying direction. It is located at the rear side of the upper frame, and its front end is connected to the rear end of the upper frame. The arrangement of the front support beam 170 and the rear support beam 180 increases the support area of the entire main support frame.

[0066] In some embodiments of the present invention, the main support frame further includes two diagonal supports. Two front support beams 170 are provided, each connected to the two front corners of the upper frame. The lower end of each diagonal support is connected to the middle portion of a corresponding first leg 120, and the upper end of each diagonal support is connected to a corresponding front support beam 170. The diagonal supports increase the support strength of the front support beams 170.

[0067] In some embodiments of the present invention, Figure 3As shown, the vibrating screen 200 also includes a power motor 600, which is installed on a lateral side of the housing 210. The maintenance platform includes a first front maintenance platform 410, a second front maintenance platform 430, and a rear maintenance platform 420. The first front maintenance platform 410 and the second front maintenance platform 430 are respectively installed above the corresponding two front support beams 170, and the first front maintenance platform 410 is close to the power motor. There are two rear support beams 180, and the two rear support beams 180 are respectively connected to the two rear corners of the main support frame. The rear maintenance platform 420 is installed above the two rear support beams 180.

[0068] The provision of the first front maintenance platform 410 , the second front maintenance platform 430 and the rear maintenance platform 420 facilitates maintenance personnel to observe and repair the vibrating screen 200 .

[0069] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the ladder assembly 500 includes a ladder 510, a first step 520, and a second step 530. The ladder 510 is disposed between the first front maintenance platform 410 and the ground. The first step 520 connects the first front maintenance platform 410 and the rear maintenance platform 420. The second step 530 connects the second front maintenance platform 430 and the rear maintenance platform 420.

[0070] In some embodiments of the present invention, the inclination angle of each layer of screen 220 is adjustable.

[0071] Furthermore, in some embodiments of the present invention, the housing 210 includes a rear mounting plate having a plurality of mounting holes 211 spaced apart in the height direction, and the rear end of a screen 220 is mounted in a corresponding mounting hole 211. A groove is provided on the lower wall of each mounting hole 211, extending along the length of the wall, and a lifting mechanism is slidably disposed within the groove, the lifting mechanism being configured to raise the height of the rear end of the screen 220 within the mounting hole 211.

[0072] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the lifting mechanism includes a base 710, a lifting seat 740, a first connecting rod 720 and a second connecting rod 730. The base 710 is movably arranged along the length direction of the groove, as shown in FIG. Figure 5As shown, the base is arranged horizontally, and the base 710 has an initial position at one end of the groove. The base 710 has two ends, namely a first end and a second end, and the second end is close to the other end of the groove. The lifting seat 740 is above the base 710 and parallel to the base. The lifting seat 740 has two ends, namely a third end and a fourth end, and the fourth end is close to the other end of the groove. Compared with the first end, the third end is closer to the other end of the groove. Compared with the second end, the fourth end is closer to the other end of the groove. The first connecting rod 720 is connected to the first end and the third end. The second connecting rod 730 is connected to the second end and the fourth end. When the first connecting rod 720 and the second connecting rod 730 are arranged vertically, the upper surface of the lifting seat 740 is higher than the bottom wall of the mounting hole 211.

[0073] When it is necessary to lift the screen 220, Figure 6 As shown, the base 710 moves from the initial position to the other end of the groove, and drives the lifting seat 740, the first connecting rod 720 and the second connecting rod 730 to move toward the other end of the groove. During the movement, the fourth end of the lifting seat 740 first collides with the side wall of the other end of the groove and stops moving. The base 710 continues to move, pushing the first connecting rod 720 and the second connecting rod 730 to rotate, and the lifting seat 740 is raised until the first connecting rod 720 and the second connecting rod 730 are vertical. The height of the lifting seat 740 is higher than the bottom wall of the mounting hole 211, and the lifting seat 740 lifts the screen 220, thereby changing the inclination angle of the screen 220.

[0074] Furthermore, in some embodiments of the present invention, a through hole is formed on a side wall at one end of the groove, and the through hole passes through the rear mounting plate transversely.

[0075] The vibrating screen 200 includes a cylinder, a piston rod 810 of the cylinder is inserted into the through hole, and the piston rod 810 is connected to a first end of the base 710 .

[0076] When the screen 220 needs to be lifted, the cylinder works, the piston rod 810 extends, and pushes the base 710 to move toward the other end of the groove, thereby causing the lifting seat 740 to rise.

[0077] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
