DETAILED DESCRIPTION
[0027] In order to make the technical personnel in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.
[0028] With reference to Figure 1 and Figure 2 , the screening machine in an embodiment of the present application comprises a feeding mechanism 1, a screening mechanism mounted at the discharging end of the feeding mechanism 1, and a first vibrating member 3 for driving the screening mechanism to vibrate.
[0029] With reference to Figure 2, the screening mechanism comprises at least two levels of screening assemblies 2, each of the screening assemblies 2 comprises a guide member for guiding the movement of the material and a screening member for screening the material, and the first vibrating member 3 drives the material to move from the guide member to the screening member. The at least two levels of screening assemblies 2 are stacked and staggered, so that the screening member of the upper screening assembly 2 corresponds to the position of the guide member of the adjacent lower screening assembly 2.
[0030] Therefore, when screening the material, the feeding mechanism 1 can deliver the material to the screening mechanism, and the first vibrating member 3 drives the screening mechanism to vibrate, so that the material in each screening assembly 2 can move from the guide member to the screening member, and the material is screened by the screening member, so that the material meeting the requirements of the screening assembly 2 is screened out. Since each screening assembly 2 can screen out the corresponding material, the screening efficiency of the material is effectively improved. Since the guide member can guide the movement of the material to the screening member, the possibility of the material remaining in the screening assembly 2 is reduced.
[0031] Referring to Figure 2 In the embodiment, the screening mechanism is provided with two levels of screening assemblies 2, which is not a limitation on the number of screening assemblies 2 of the present application. In other embodiments, the screening assemblies 2 can be provided with three, four or more levels.
[0032] Referring to Figure 2 and Figure 3 , the screening mechanism comprises a first level of screening assembly and a second level of screening assembly, the screening member of the first level of screening assembly comprises a screening plate 22 with a plurality of screen holes, and the screening member of the second level of screening assembly comprises a plurality of screening strips 23 with a preset interval. It can be understood that the size of the screen holes of the screening plate 22 and the preset interval of the screening strips 23 are set according to actual requirements, so as to screen out the material meeting the corresponding size requirements. In the embodiment, the first level of screening assembly and the second level of screening assembly are stacked, and the first level of screening assembly is located above the second level of screening assembly.
[0033] Referring to Figure 2 and Figure 3 , the second level of screening assembly further comprises a mounting frame 24 and a mounting seat 25 fixedly connected with the mounting frame 24, the mounting seat 25 is provided with a limiting hole, the screening strip 23 is clamped in the limiting hole, and a plurality of screening strips 23 are arranged in an array. The array distance of the array arrangement is the preset distance between the screening strips 23.
[0034] Referring to Figure 3 and Figure 4The guide member includes a guide plate 21, and the guide plate 21 is provided with a plurality of guide grooves, and the extension direction of the guide grooves is used to guide the material to move to the screening member. In the embodiment, the guide member of the first-stage screening assembly and the second-stage screening assembly are both provided as the guide plate 21, and the guide plate 21 of the first-stage screening assembly is integrally formed with the screening plate 22 of the first-stage screening assembly; and the guide plate 21 of the second-stage screening assembly is independently separated from the screening strip 23 of the second-stage screening assembly.
[0035] Further, in the embodiment, the extension direction of each screening strip 23 is the same as the moving direction of the material driven by the first vibrator 3. Therefore, the material located on the screening strip 23 can continue to move under the guidance of the screening strip 23.
[0036] With reference to Figure 2 , the screening machine further includes a mounting frame 4 with a bottom plate 41, and the screening mechanism is mounted on the mounting frame 4, and the bottom plate 41 includes a good product area and a defective product area, and the defective product area corresponds to the position of the screening member of the screening assembly 2 located at the lowermost layer. The discharge end of the good product area is provided with a first receiving box 5; and the discharge end of the defective product area is provided with a second receiving box 6.
[0037] Therefore, the material meeting the requirements can move to the good product area under the guidance of the screening strip 23, and finally fall into the first receiving box 5. The material not meeting the requirements leaves the screening strip 23 and falls into the defective product area, and finally falls into the second receiving box 6.
[0038] In order to prevent the materials between the good product area and the defective product area from being mixed under the vibration of the first vibrator 3, in the embodiment, a partition plate is arranged between the good product area and the defective product area to make them independent of each other.
[0039] With reference to Figure 1 and Figure 5 , the feeding mechanism 1 includes a hopper 11 for placing the material, a flow guide plate 12 located at the discharge end of the hopper 11, and a second vibrator 13 for driving the flow guide plate 12 to vibrate; wherein the discharge port of the flow guide plate 12 corresponds to the position of the guide member of the uppermost screening assembly 2, and the second vibrator 13 is used to drive the material away from the flow guide plate 12. Therefore, after the material in the hopper 11 falls into the flow guide plate 12, the second vibrator 13 can make the material on the flow guide plate 12 fall onto the screening mechanism, so as to ensure the automatic operation of the material screening, thereby improving the screening efficiency of the material. In the embodiment, the flow guide plate is located above the guide member of the first-stage screening assembly.
[0040] With reference to Figure 1 and Figure 5Further, the drainage plate 12 comprises at least two sub-flow channels, and a set of screening mechanisms is arranged at the discharge port of each sub-flow channel.
