[0036] like Figures 1 and 2As shown, this embodiment provides a screening machine, including a frame 1, a screening component 2 and a driving mechanism 3, the screening component 2 includes a first elastic belt 21, a second elastic belt 22, a driving shaft 23, a first driven shaft 24 and a second driven shaft 25, the driving shaft 23, the first driven shaft 24 and the second driven shaft 25 are arranged on the frame 1 in parallel, spaced and rotatable along the length direction of the frame 1, the driving shaft 23 and the first driven shaft 24 jointly tension each first elastic belt 21, the driving shaft 23 and the second driven shaft 25 jointly tension each second elastic belt 22, the first elastic belt 21 and the second elastic belt 22 are staggered and spaced, and the spacing between each first elastic belt 21 and the adjacent second elastic belt 22 is the same; the driving mechanism 3 is arranged on the frame 1, and one end of the driving shaft 23 is transmission-connected to the output end of the driving mechanism 3 to drive the driving shaft 23 to rotate. Between the driving shaft 23 and the first driven shaft 24, since the first elastic belt 21 and the second elastic belt 22 are staggered and spaced apart, and the spacing between each first elastic belt 21 and the adjacent second elastic belt 22 is the same, the spacing is the primary screen width of the screening machine; it is easy to understand that the spacing between two adjacent second elastic belts 22 is also the same, and the spacing is the secondary screen width of the screening machine, so that the material can be screened at the secondary level according to the size of different materials; by changing the number or spacing of the first elastic belt 21 and the second elastic belt 22, the size of the primary screen width and the secondary screen width can be adjusted, so that the screening machine It is suitable for screening materials of various sizes; it can realize the automation of the entire screening process, and screening can be performed along the entire length of the first elastic belt 21 and the second elastic belt 22, which increases the screening operation area and is conducive to improving the screening efficiency; by stretching the first elastic belt 21 and the second elastic belt 22, they can be easily removed from the driving shaft 23, the first driven shaft 24 or the second driven shaft 25, or they can be tensioned on the driving shaft 23, the first driven shaft 24 or the second driven shaft 25, and when the first elastic belt 21 or the second elastic belt 22 is worn, they can be easily replaced.

[0037] In addition, the first elastic belt 21 and the second elastic belt 22 can realize both transmission function and screening function, which makes the structure of the screening machine simple and helps to reduce the manufacturing cost, volume and weight of the screening machine, making the screening machine easy to carry.

[0038] The driving mechanism 3 includes but is not limited to a motor or a cylinder, etc., which is not limited here.

[0039] Optionally, the screening assembly 2 may further include a third elastic belt and a third driven shaft. The driving shaft 23, the first driven shaft 24, the second driven shaft 25, and the third driven shaft are sequentially arranged parallel to and rotatably on the frame 1 along the length of the frame 1. The driving shaft 23 and the third driven shaft jointly tension the third elastic belt to achieve three-stage screening of the material. Similarly, multi-stage screening can be achieved by increasing the number of driven shafts and elastic belts according to the requirements for multi-stage screening of the material, and this is not specifically limited.

[0040] like Figure 2 As shown, the screening machine also includes a guard plate assembly 4, which includes a plurality of first guard plates 41 and a plurality of second guard plates 42. By providing a corresponding first guard plate 41 between the upper inner surface and the lower inner surface of each first elastic band 21, it is possible to prevent the material from hanging on the lower inner surface of the first elastic band 21 when falling. Similarly, by providing a corresponding second guard plate 42 between the upper inner surface and the lower inner surface of each second elastic band 22, it is possible to prevent the material from hanging on the lower inner surface of the second elastic band 22 when falling, thereby ensuring the normal operation of the screening machine.

[0041] Furthermore, the guard plate assembly 4 also includes a first support beam 43 and a second support beam 44, and the first support beam 43 and the second support beam 44 are both arranged on the frame 1. A first bayonet is provided on the first guard plate 41, and a second bayonet is provided on the second guard plate 42. The first support beam 43 is arranged between the driving shaft 23 and the first driven shaft 24, and the first support beam 43 is plugged into and matched with the corresponding first bayonet and second bayonet, thereby providing support for the first guard plate 41 and the second guard plate 42 between the driving shaft 23 and the first driven shaft 24 to prevent them from tipping over; the second support beam 44 is arranged between the first driven shaft 24 and the second driven shaft 25, and the second support beam 44 is plugged into and matched with the corresponding second bayonet, thereby providing support for the second guard plate 42 between the first driven shaft 24 and the second driven shaft 25 to prevent it from tipping over.

[0042] Furthermore, the guard plate assembly 4 also includes a plurality of snap rings 45, and each first support beam 43 and each second support beam 44 are provided with a plurality of snap rings 45 at intervals. The first guard plate 41 or the second guard plate 42 is snapped into the slot formed by the corresponding two adjacent snap rings 45, thereby facilitating the fixing of the spacing between the first guard plate 41 or the second guard plate 42 to prevent them from shifting and obstructing the falling of materials.

[0043] In this embodiment, three first support beams 43 are spaced between the driving shaft 23 and the first driven shaft 24, and three second support beams 44 are spaced between the first driven shaft 24 and the second driven shaft 25. These beams 43 and 44 provide better support and fixation for the first and second guard plates 41 and 42, preventing them from tilting or shifting. In other embodiments, the number of first and second support beams 43 and 44 can be adapted to the lengths of the first and second elastic bands 21 and 22, such as one, two, four, or seven. To prevent dirt from entering the gap between the first elastic band 21 and the first guard plate 41, first grooves are provided at both the upper and lower ends of the first guard plate 41. These grooves are designed to engage with the first elastic band 21, allowing the first elastic band 21 to fit tightly against the upper and lower ends of the first guard plate 41. This reduces the gap between the first elastic band 21 and the first guard plate 41 and prevents material or dust from entering between the first elastic band 21 and the first guard plate 41. Similarly, second grooves are provided at the upper and lower ends of the second guard plate 42, and the second grooves are used to engage with the second elastic band 22, thereby reducing the gap between the second elastic band 22 and the second guard plate 42, which helps to keep the second elastic band 22 and the second guard plate 42 clean.

[0044] To facilitate securing the first and second elastic bands 21, 22, the driving shaft 23, the first driven shaft 24, and the second driven shaft 25 are each provided with a plurality of evenly spaced grooves. These grooves are used to engage with the first and second elastic bands 21, 22. By engaging the ends of the first and second elastic bands 21, 22 in the corresponding grooves, the belts are evenly spaced apart, preventing them from sliding on the driving shaft 23, the first driven shaft 24, or the second driven shaft 25. Optionally, depending on the requirements for the primary and secondary screen widths, the operator can replace the driving shaft 23, the first driven shaft 24, and the second driven shaft 25 with grooves of varying spacing, thereby adapting the screening machine to screen materials of varying sizes.

[0045] Furthermore, the first elastic band 21 and the second elastic band 22 are both cylindrical strips, which can reduce friction between the first elastic band 21 and the second elastic band 22 and the material, preventing the material from hanging on the first elastic band 21 and the second elastic band 22. In other embodiments, the first elastic band 21 and the second elastic band 22 include but are not limited to flat square strips or strips with arc-shaped cross-sections, which are not limited here.

[0046] In some embodiments, the first elastic band 21 and the second elastic band 22 are both polyurethane bands, which have good elasticity and wear resistance and are inexpensive.

[0047] In other embodiments, the driving shaft 23, the first driven shaft 24 and the second driven shaft 25 are all rubber rollers. The surface friction of the rubber rollers is large, making it difficult for the first elastic band 21 and the second elastic band 22 to slide relative to the surface of the rubber rollers, and the rubber material is convenient for processing belt grooves, so that the first elastic band 21 and the second elastic band 22 can be fixed in the belt grooves.

[0048] Optionally, the screening machine further includes a tensioning roller 5 rotatably mounted on the frame 1 and positioned below the first elastic belt 21 and the second elastic belt 22 to tension the first elastic belt 21 and / or the second elastic belt 22. Furthermore, positioning the tensioning roller 5 below the first elastic belt 21 and the second elastic belt 22 helps reduce the size of the screening machine. In this embodiment, a tensioning roller 5 is positioned between the driving shaft 23 and the first driven shaft 24, and a tensioning roller 5 is also positioned between the first driven shaft 24 and the second driven shaft 25, thereby further enhancing tensioning of the first elastic belt 21 and the second elastic belt 22. In other embodiments, the number of tensioning rollers 5 may be adapted to the length of the first elastic belt 21 and the second elastic belt 22, without limitation herein.

[0049] This embodiment also provides a classification and recovery device, including a first collecting piece, a second collecting piece and the above-mentioned screening machine, the first collecting piece is used to collect materials falling from between the driving shaft 23 and the first driven shaft 24, and the second collecting piece is used to collect materials falling from between the first driven shaft 24 and the second driven shaft 25, so as to transport the screened materials to the next processing link for processing.

[0050] Furthermore, the classification and recovery device also includes a third collecting member for collecting materials that are too large to fall between the first driven shaft 24 and the second driven shaft 25, so as to facilitate their transportation to the next processing link for processing.

[0051] It should be noted that the screening machine provided in this application is not only suitable for the classification and recycling of garbage, but also for screening other materials that need to be classified according to size.
