Description

Technical Field

[0001] This application relates to the field of screening equipment technology, and more specifically, to a screening and separating machine for mixed materials. Background Technology

[0002] Currently, most mixed material screening equipment in related technologies suffers from limited functionality, only capable of basic screening using a single-stage fixed screen. They cannot simultaneously achieve anti-clogging vibration, multi-stage fine separation, and automatic material distribution. During operation, additional vibrating motors are required to drive each stage of the screens, resulting in complex structures, increased energy consumption, and frequent shutdowns for cleaning due to material jamming. This significantly reduces continuous operation efficiency and increases maintenance costs. Summary of the Invention

[0003] This application aims to at least solve the technical problems in the related technologies, such as the inability of traditional mixed material screening equipment to simultaneously achieve anti-clogging vibration and multi-stage fine separation functions, the need to configure additional vibration motors to drive each stage of the screen during operation, resulting in complex structure, increased energy consumption, and frequent shutdowns for cleaning due to material jamming of the screen, which reduces continuous operation efficiency and increases maintenance costs.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a mixed material screening and separation machine, comprising: a housing; a first filter assembly movably connected to the housing and inclined relative to the side wall of the housing; a second filter assembly movably connected to the housing, located below the first filter assembly and inclined relative to the side wall of the housing; and a rotating assembly disposed between the first filter assembly and the second filter assembly. The rotating assembly includes a rotating wheel and a plurality of arc-shaped protrusions, the plurality of arc-shaped protrusions being evenly distributed around the circumference of the rotating wheel, and at least some of the arc-shaped protrusions respectively abutting against the first filter assembly and the second filter assembly; wherein, when the rotating assembly rotates, the arc-shaped protrusions periodically lift the first filter assembly and periodically impact the second filter assembly, causing the first filter assembly and the second filter assembly to vibrate, thereby screening and separating the materials.

[0006] The mixed material screening and separating machine provided in this application includes a shell, a first filter assembly, a second filter assembly, and a rotating assembly. The first and second filter assemblies are movably connected to the sidewall of the shell and are inclined relative to the sidewall. The first and second filter assemblies are arranged vertically relative to each other, with the same inclination direction relative to the sidewall, and are generally parallel to each other. The rotating assembly is located between the first and second filter assemblies and includes a rotating wheel and multiple arc-shaped protrusions. The arc-shaped protrusions are evenly distributed around the circumference of the rotating wheel, and at least some of the arc-shaped protrusions abut against the first and second filter assemblies. When the rotating assembly rotates, the arc-shaped protrusions periodically lift the first filter assembly and periodically impact the second filter assembly, causing the first and second filter assemblies to vibrate, thereby screening and separating the materials.

[0007] Specifically, during the continuous rotation of the rotating component, multiple arc-shaped protrusions on the circumference of its rotating wheel synchronously perform bidirectional drive. For the first filter component, the arc-shaped protrusions periodically lift the inclined filter element, forcing the filter element to generate a composite vibration in the inclined direction around its movable connection point. The composite vibration includes lifting motion and resetting oscillation. For the second filter component, the arc-shaped protrusions periodically impact the inclined second filter component below, driving the second filter component to generate linear vibration perpendicular to the screen surface. By simultaneously driving the vibration of the upper and lower filter components with a single rotating component, the material, after coarse screening on the surface of the first filter component, falls directly into the second filter component for fine classification, achieving dual-stage synchronous screening, that is, realizing continuous two-stage screening assembly line operation. Moreover, the composite vibration of the first filter component effectively prevents material accumulation and blockage, while the vertical vibration of the second filter component improves the screening efficiency of fine particles, and the dual modes complement each other to optimize screening accuracy. In addition, by replacing the traditional multi-motor drive scheme with the mechanical linkage of the rotating arc-shaped protrusions, the number of power components is reduced, significantly reducing equipment complexity and energy consumption.

[0008] This application provides a mixed material screening and separation machine. Through the coordinated vibration structure of a rotating component and a dual-filter component, it achieves functional integration and efficient screening. In the primary screening stage, the arc-shaped protrusions of the rotating component periodically lift the inclined filter element, driving the slider to slide along the chute and compress the first elastic element, causing the filter element to generate compound vibration. This effectively shakes off fine particles and prevents clogging, while large particles slide along the inclined surface into the collecting component. In the secondary fine screening stage, the arc-shaped protrusions of the same rotating component synchronously impact the lower filter plate, driving the moving block to compress the second elastic element, causing the filter plate to vibrate vertically, thus performing secondary screening of the fine particles. In the multi-stage distribution stage, large particles are guided by the inclined flow of the collecting component and discharged from the main distribution port, medium particles are discharged from the secondary distribution port along the inclined surface of the filter plate, and fine materials fall directly through the filter plate into the bottom discharge port, forming a three-stage continuous separation channel. Without the need for multiple vibration motors, a single rotating component driving dual-stage coordinated vibration can simultaneously complete anti-clogging shaking, particle size classification, and directional distribution, significantly improving screening efficiency and continuity.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] The following reference Figures 1 to 5 This application describes a mixture screening and separating machine 100 provided according to some embodiments of the present application.

[0021] like Figures 1 to 5 As shown, Figure 1 This is one of the structural schematic diagrams of a mixture screening and separating machine 100 according to an embodiment of this application; Figure 2 This is a second schematic diagram of the structure of a mixture screening and separating machine 100 according to one embodiment of this application; Figure 3 This is the third schematic diagram of the structure of a mixture screening and separating machine 100 according to one embodiment of this application; Figure 4 This is a schematic diagram of the structure of the first filter component 120 in a mixed material screening and separating machine 100 according to an embodiment of this application; Figure 5 This is a schematic diagram of the structure of the second filter component 130 in a mixture screening and separating machine 100 according to an embodiment of this application.

[0022] like Figures 1 to 5As shown, an embodiment of this application provides a mixed material screening and separation machine 100, comprising: a housing 110; a first filter assembly 120, movably connected to the housing 110 and inclined relative to the side wall of the housing 110; a second filter assembly 130, movably connected to the housing 110, located below the first filter assembly 120 and inclined relative to the side wall of the housing 110; and a rotating assembly 140, disposed between the first filter assembly 120 and the second filter assembly 130, the rotating assembly 140 including... The rotating wheel 142 and a plurality of arc-shaped protrusions 144 are evenly distributed on the periphery of the rotating wheel 142, and at least some of the arc-shaped protrusions 144 abut against the first filter assembly 120 and the second filter assembly 130 respectively; wherein, when the rotating assembly 140 rotates, the arc-shaped protrusions 144 periodically lift the first filter assembly 120 and periodically impact the second filter assembly 130, so that the first filter assembly 120 and the second filter assembly 130 vibrate, thereby screening and separating the material.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the mixed material screening and separating machine 100 provided in this application includes a housing 110, a first filter assembly 120, a second filter assembly 130, and a rotating assembly 140. The first filter assembly 120 and the second filter assembly 130 are movably connected to the side wall of the housing 110 and are inclined relative to the side wall of the housing 110. The first filter assembly 120 and the second filter assembly 130 are arranged vertically relative to each other and in the same direction of inclination relative to the side wall of the housing 110. The first filter assembly 120 and the second filter assembly 130 are generally parallel to each other. The rotating assembly 140 is disposed between the first filter assembly 120 and the second filter assembly 130. The rotating assembly 140 includes a rotating wheel 142 and a plurality of arc-shaped protrusions 144. The plurality of arc-shaped protrusions 144 are evenly distributed on the periphery of the rotating wheel 142, and at least some of the arc-shaped protrusions 144 abut against the first filter assembly 120 and the second filter assembly 130, respectively. When the rotating component 140 rotates, the arc-shaped protrusion 144 periodically lifts the first filter component 120 and periodically impacts the second filter component 130, causing the first filter component 120 and the second filter component 130 to vibrate, thereby screening and separating the material.

[0024] Specifically, during the continuous rotation of the rotating component 140, multiple arc-shaped protrusions 144 on the periphery of its rotating wheel 142 synchronously perform bidirectional driving. For the first filter component 120, the arc-shaped protrusions 144 periodically lift the inclined filter element 122, forcing the filter element 122 to generate a composite vibration in the inclined direction around its movable connection point. The composite vibration includes lifting motion and resetting oscillation. For the second filter component 130, the arc-shaped protrusions 144 periodically impact the inclined second filter component 130 below, driving the second filter component 130 to generate linear vibration perpendicular to the screen surface. By simultaneously driving the vibration of the upper and lower filter components through a single rotating component 140, the material, after coarse screening on the surface of the first filter component 120, directly falls into the second filter component 130 for fine classification, realizing dual-stage synchronous screening, that is, realizing continuous two-stage screening streamlined operation. Moreover, the composite vibration of the first filter component 120 effectively prevents material accumulation and clogging, while the vertical vibration of the second filter component 130 improves the screening efficiency of fine particles. The dual modes complement each other to optimize screening accuracy. In addition, by replacing the traditional multi-motor drive scheme with a rotating protrusion mechanical linkage, the number of power components is reduced, significantly reducing equipment complexity and energy consumption.

[0025] Specifically, currently, when existing material screening equipment filters materials, larger materials may get stuck in the filter holes on the surface of the filter plate, preventing effective filtration and separation. Furthermore, existing mixed material screening equipment generally suffers from limited functionality, only capable of basic screening using a single-stage fixed screen, unable to simultaneously achieve anti-clogging vibration, multi-stage fine separation, and automatic material distribution functions. During operation, additional vibrating motors are required to drive each stage of the screens, resulting in complex structure, increased energy consumption, and frequent shutdowns for cleaning due to material jamming, significantly reducing continuous operation efficiency and increasing maintenance costs.

[0026] To address the shortcomings of existing technologies, the purpose of this application is to provide a mixed material screening and separation machine 100, which solves the technical problems of traditional mixed material screening equipment being unable to simultaneously achieve anti-clogging vibration and multi-stage fine separation functions, and requiring additional vibration motors to drive each stage of the screens during operation, resulting in complex structure, increased energy consumption, and frequent shutdowns for cleaning due to material jamming, thus reducing continuous operation efficiency and increasing maintenance costs.

[0027] Specifically, to prevent material from clogging the filter element 122, the first filter assembly 120 is tilted when the material enters from the feed element 170, allowing it to filter the material. While the material moves within the first filter assembly 120, the drive assembly 192 is activated, causing the rotating assembly 140 to rotate. This causes the arc-shaped protrusion 144 on the outer surface of the rotating assembly 140 to strike the bottom of the first filter assembly 120, raising one end of the first filter assembly 120 and allowing the slider 125 to move within the groove 124. The slide block 125 moves upward inside the longitudinal movable groove 112, pressing the first elastic element 126. The elastic force of the first elastic element 126 pushes the slide block 125 to reset the filter element 122. This causes the filter element 122 to vibrate when filtering materials, allowing smaller materials to slide off and larger materials to enter the collection member 128. This effectively prevents materials from clogging the filter element 122. When the filter element 122 vibrates, larger materials inside the collection member 128 are ejected from the collection member 128 and flow out from the main feed port 150 along the inclined surface set on the inner wall side of the collection member 128.

[0028] To ensure more complete material filtration by the mixed material screening and separator 100, the rotating component 140 impacts the upper surface of the second filter component 130 during rotation. This causes the filter plate 132 in the second filter component 130 to move downwards, and the filter plate 132 drives the moving block 136 to move downwards. Simultaneously, the moving block 136 presses against the second elastic element 138, causing the filter plate 132 to filter the material again. The elastic force of the second elastic element 138 causes the filter plate 132 to reset, allowing the filtered material to be discharged from the housing 110 through the discharge port 116. At the same time, the material on the upper surface of the filter plate 132 is discharged from the secondary discharge port 160 as the filter plate 132 is tilted. This allows the mixed material screening and separator 100 to better separate the materials.

[0029] This application provides a mixed material screening and separation machine 100, which achieves functional integration and efficient screening through the coordinated vibration structure of a rotating component 140 and a dual filter component. In the primary screening stage, the arc-shaped protrusion 144 of the rotating component 140 periodically lifts the inclined filter element 122, driving the slider 125 to slide along the slide groove 124 and compress the first elastic element 126, causing the filter element 122 to generate compound vibration, effectively shaking off fine particles and preventing clogging, while large particles slide into the collection member 128 along the inclined surface; in the secondary fine screening stage, the arc-shaped protrusion 144 of the same rotating component 140 synchronously impacts the lower filter plate 13. 2. The driving moving block 136 compresses the second elastic element 138, causing the filter plate 132 to vibrate vertically, thus performing secondary screening of fine particles. In the multi-stage material distribution stage, large particles are guided by the collection element 128 and discharged from the main distribution port 150, medium particles are discharged from the secondary distribution port 160 along the inclined surface of the filter plate 132, and fine particles fall directly through the filter plate 132 into the bottom discharge port 116, forming a three-stage continuous separation channel. Without the need for multiple vibration motors, the dual-stage coordinated vibration driven by a single rotating component 140 can be used to simultaneously complete anti-clogging shaking, particle size classification, and directional material distribution, significantly improving screening efficiency and continuity.

[0030] In specific applications, the mixed material screening and separation machine 100 can be specifically a mixed fertilizer screening and separation machine, and the arc-shaped protrusion 144 can be specifically set as an arc-shaped protrusion. It can be selected according to the actual use situation, and will not be listed here.

[0031] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, a longitudinal movable groove 112 is provided on the side wall of the housing 110. The first filter assembly 120 includes: a filter element 122, on which a first filter hole 123 is provided, and a sliding groove 124 is provided on the side of the filter element 122; a slider 125, one end of which is slidably connected to the longitudinal movable groove 112, and the other end of which is slidably connected to the sliding groove 124; and a first elastic element 126, one end of which is connected to the top of the longitudinal movable groove 112, and the other end of which is connected to the slider 125. When the rotating assembly 140 rotates, the arc-shaped protrusion 144 pushes up the bottom of the filter element 122, causing the slider 125 to compress the first elastic element 126. The filter element 122 generates a compound motion under the constraint of the slider 125 and the sliding groove 124. When the arc-shaped protrusion 144 separates from the filter element 122, the first elastic element 126 extends and pushes the slider 125 and the filter element 122 to reset.

[0032] Specifically, such as Figure 2 and Figure 4As shown, the first filter assembly 120 includes a filter element 122, a slider 125, and a first elastic element 126. The filter element 122 has a first filter hole 123 for filtering materials, and a groove 124 is formed on its side. One end of the slider 125 is slidably connected to a longitudinal movable groove 112, and the other end is slidably connected to the groove 124. One end of the first elastic element 126 is connected to the top of the longitudinal movable groove 112, and the other end is connected to the slider 125. Thus, when the rotating assembly 140 rotates, the arc-shaped protrusion 144 lifts the bottom of the filter element 122, causing the slider 125 to compress the first elastic element 126. The filter element 122 undergoes a combined motion under the constraint of the slider 125 and the groove 124. When the arc-shaped protrusion 144 separates from the filter element 122, the first elastic element 126 extends and pushes the slider 125 and the filter element 122 back to their original positions.

[0033] Specifically, through the two-degree-of-freedom sliding pair formed by the slider 125 and the slide groove 124, and the elastic reset action of the first elastic element 126, when the arc-shaped protrusion 144 lifts the bottom of the filter element 122, the slider 125 moves upward along the longitudinal movable groove 112 to compress the first elastic element 126. At the same time, the slider 125 slides laterally within the slide groove 124, forcing the filter element 122 to produce a combined lifting and oscillating motion, thoroughly dispersing material clumps and preventing blockage of the first filter hole 123. When the arc-shaped protrusion 144 disengages, the first elastic element 126 pushes the slider 125 to reset, causing the filter element 122 to rebound at high speed, making the material evenly spread on the screen surface and allowing fine particles to pass through the screen quickly. The sliding friction of the slider 125 within the slide groove 124 replaces the traditional hinge structure, reducing wear points and extending the equipment life.

[0034] In specific applications, the longitudinal movable groove 112 is a movable groove opened vertically on the side wall of the housing 110. It can be selected according to the actual use situation and will not be listed here.

[0035] In some embodiments, optionally, such as Figure 1 , Figure 2 and Figure 3 As shown, a main feed inlet 150 is provided on the side wall of the housing 110, a feed member 170 is provided on the top of the housing 110, the filter member 122 has a hollow internal structure, a feed inlet 127 is provided at one end of the filter member 122, and a collection member 128 is provided at the other end of the filter member 122. The bottom opening of the feed member 170 corresponds to the feed inlet 127, and the inner wall of the collection member 128 is inclined, and the inclined surface extends toward the main feed inlet 150.

[0036] Specifically, by precisely aligning the bottom of the feed element 170 with the feed inlet 127 of the filter element 122, and by extending the inclined inner wall of the assembly 128 towards the main discharge port 150, materials are directly injected into the hollow cavity of the filter element 122 via the feed element 170, preventing spillage during the feeding process. Large particles slide directionally into the main discharge port 150 along the inclined inner wall of the assembly 128, improving flow efficiency. Furthermore, the inclined inner wall of the assembly 128 and the main discharge port 150 form a guiding channel, completely eliminating the risk of material accumulation at corners. In addition, the hollow structure of the filter element 122 integrates material storage and flow guidance functions, reducing vertical space occupancy compared to traditional split-type hoppers.

[0037] In specific applications, the filter element 122 can be specifically configured as a double-layer screen structure with a cavity inside. One end of the double-layer screen structure is provided with a feed inlet 127, and the other end is provided with a collection element 128. The specific configuration can be selected according to the actual application, and will not be listed here.

[0038] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the mixed material screening and separation machine 100 also includes: a guide block 180, which is disposed at the bottom of the inner wall of the main material outlet 150. The upper surface of the guide block 180 is inclined, and the inclined surface of the guide block 180 and the inclined surface of the collection member 128 form a continuous material guiding channel.

[0039] Specifically, such as Figure 2 As shown, the inclined upper surface of the guide block 180 seamlessly connects with the inclined inner wall of the assembly 128 to form a continuous material guiding channel. This minimizes the transition angle difference between the material and the inner wall of the assembly 128 and the surface of the guide block 180, facilitating turbulent, continuous sliding and increasing the discharge speed of large particles. The inclined surface of the guide block 180 extends to the edge of the main discharge port 150, forming a wraparound guide track to eliminate rebound and splashing caused by material impacting the side wall of the discharge port. The combination of the two inclined surfaces forms a material guiding channel, which, combined with the gravity flushing of the material, prevents residue accumulation.

[0040] In some embodiments, optionally, such as Figure 2 As shown, the mixed material screening and separation machine 100 also includes a baffle 190, which is disposed on the inner wall of the housing 110 near the main feed inlet 150 to limit the displacement range of the collection component 128.

[0041] Specifically, the mixed material screening and separating machine 100 also includes a baffle 190. The baffle 190 is located on the inner wall of the housing 110 near the main feed inlet 150, and is used to limit the displacement range of the collecting component 128. By setting the baffle 190, the displacement range of the collecting component 128 can be limited, allowing the collecting component 128 to align with the guide block 180, achieving turbulent-free continuous sliding and increasing the discharge speed of large particles.

[0042] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, a longitudinal moving groove 114 is provided on the side wall of the housing 110. The second filter assembly 130 includes: a filter plate 132 with a second filter hole 134; a moving block 136, one end of which is fixedly connected to the filter plate 132 and the other end is slidably connected to the longitudinal moving groove 114; and a second elastic member 138, one end of which is connected to the top of the longitudinal moving groove 114 and the other end of which is connected to the moving block 136. When the rotating assembly 140 rotates, the arc-shaped protrusion 144 impacts the upper surface of the filter plate 132, causing the filter plate 132 to move downward and compress the second elastic member 138. When the arc-shaped protrusion 144 separates from the filter plate 132, the second elastic member 138 extends and pushes the moving block 136 and the filter plate 132 to reset, so that the filter plate 132 vibrates up and down.

[0043] Specifically, such as Figure 5 As shown, the second filter assembly 130 includes a filter plate 132, a moving block 136, and a second elastic element 138. Through the rigid guidance of the moving block 136 and the longitudinal moving groove 114, and the elastic energy storage function of the second elastic element 138, when the arc-shaped protrusion 144 impacts the filter plate 132, the moving block 136 moves vertically downwards along the longitudinal moving groove 114, compressing the second elastic element 138. The vibration direction has a small angle with the normal to the screen surface, enabling fine particles to obtain maximum bouncing kinetic energy through the screen, thus improving screening efficiency. Furthermore, the sliding pair between the moving block 136 and the longitudinal moving groove 114 constrains the vibration trajectory, eliminating uneven wear caused by lateral displacement and extending the lifespan of the second filter assembly 130. In addition, the impact kinetic energy is converted into the elastic potential energy of the second elastic element 138. Upon resetting, the potential energy is released, driving the filter plate 132 to rebound at high speed. This reduces energy consumption compared to traditional vibration motors, saving costs.

[0044] In specific applications, the longitudinal moving groove 114 is a moving groove opened in the vertical direction along the side wall of the housing 110. It can be selected according to the actual use situation and will not be listed here.

[0045] In some embodiments, optionally, such as Figure 1 and Figure 3As shown, a secondary feed inlet 160 is provided on the side wall of the housing 110, and one end of the filter plate 132 extends above the secondary feed inlet 160.

[0046] Specifically, such as Figure 3 As shown, a secondary feed inlet 160 is provided on the side wall of the shell 110, and one end of the filter plate 132 extends above the secondary feed inlet 160. This allows the material on the filter plate 132 to be discharged from the secondary feed inlet 160, achieving particle size classification and directional material distribution, and significantly improving screening efficiency and continuity.

[0047] In some embodiments, optionally, such as Figure 4 and Figure 5 As shown, the aperture of the second filter hole 134 of the filter plate 132 is smaller than the aperture of the first filter hole 123 on the filter element 122 of the first filter assembly 120.

[0048] Specifically, by setting the aperture of the second filter hole 134 of the filter plate 132 to be smaller than the aperture of the first filter hole 123 on the filter element 122 of the first filter assembly 120, the first filter hole 123 intercepts large particles and guides them to the main feed inlet 150; the second filter hole 134 intercepts medium particles and slides them to the secondary feed inlet 160; and ultrafine particles directly pass through the screen and fall into the discharge outlet 116, realizing natural classification without power and improving the sorting accuracy.

[0049] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, a discharge port 116 is also provided on the side wall of the housing 110. The discharge port 116 is located below the bottom of the filter plate 132. The discharge port 116, the secondary discharge port 160 and the main discharge port 150 are located on three different side walls of the housing 110.

[0050] Specifically, by setting the discharge port 116, the secondary distribution port 160, and the main distribution port 150 on three different side walls of the housing 110, large particles are discharged horizontally from the right side wall through the main distribution port 150; medium particles are discharged obliquely from the right side wall through the secondary distribution port 160; and ultrafine particles are discharged obliquely from the left side wall through the discharge port 116. This three-way flow avoids material mixing, and the three-outlet three-dimensional layout reduces the lateral footprint compared to the traditional same-side outlet design, making it suitable for narrow working spaces. In addition, physical isolation between the outlets blocks airflow crosstalk, eliminating the risk of fine particles being blown back into the coarse material zone by equipment vibration.

[0051] In some embodiments, optionally, such as Figure 1 As shown, the mixed material screening and separation machine 100 also includes a drive assembly 192, which is disposed on the housing 110 and connected to the rotating wheel 142 for driving the rotating assembly 140 to rotate.

[0052] Specifically, by directly connecting the drive assembly 192 to the rotating wheel 142, the output shaft of the drive assembly 192 is rigidly coaxially connected to the rotating wheel 142, resulting in high transmission efficiency and reduced energy consumption compared to traditional belt or gear drives. Direct drive ensures synchronized lifting or impact of the arc-shaped protrusion 144, minimizing vibration timing errors in the dual-stage filtration assembly and improving screening consistency. Furthermore, the drive assembly 192 incorporates a current sensor that automatically cuts off power to the rotating wheel 142 when it is obstructed by material, preventing mechanical damage.

[0053] In specific applications, the drive component 192 can be configured as a drive motor, the first elastic element 126 can be a large spring, and the second elastic element 138 can be a medium spring. The specific choice depends on the actual application and will not be listed here.

[0054] In practical applications, the working principle of the mixed material screening and separation machine 100 is as follows:

[0055] When material enters the filter element 122 from the feed member 170, the filter element 122 is inclined to filter the material. As the material moves within the cavity of the filter element 122, the drive motor starts, causing the rotating assembly 140 to rotate. This causes the arc-shaped protrusions on the outer surface of the rotating assembly 140 to strike the bottom of the filter element 122, raising one end of the filter element 122 and allowing the slider 125 to move within the slide groove 124. Furthermore, the slider 125 moves upward within the longitudinal movable groove 112. The slider 125 presses against the large spring, and the spring force pushes the slider 125 to reset the filter element 122. This causes the filter element 122 to vibrate when filtering materials, allowing smaller materials to slide off and larger materials to enter the collection member 128. This effectively prevents materials from clogging the filter element 122. When the filter element 122 vibrates, the larger materials inside the collection member 128 are ejected from the collection member 128 and flow out from the main feed port 150 along the inclined surface set on the inner wall of the collection member 128.

[0056] When the rotating component 140 rotates, it impacts the upper surface of the filter plate 132, causing the filter plate 132 to move downwards. This causes the filter plate 132 to move the moving block 136 downwards, while the moving block 136 presses against the central spring. This causes the filter plate 132 to filter the material again, and the spring force of the central spring causes the filter plate 132 to reset. This allows the filtered material to be discharged from the housing 110 through the discharge port 116. At the same time, the material on the upper surface of the filter plate 132 will be discharged from the secondary discharge port 160 as the filter plate 132 is tilted. This allows the mixed material screening and separation machine 100 to better screen and separate the materials.
