[0002] With the continuous development and progress of industrial production, the requirements for material screening and transportation are becoming higher and higher. Therefore, vibrating plates that can screen materials have come into being. They adopt advanced vibration screening technology and material conveying technology, and have the advantages of high screening efficiency, uniform particle size distribution, and high screening accuracy. They can greatly improve production efficiency and product quality, while reducing production costs and maintenance costs.

[0003] The existing Chinese patent (application number: CN202220062813.3) proposes a vibrating plate for screening and dividing materials, including a protective shell, an electric hydraulic push rod is installed at the bottom of the inner wall of the protective shell, one end of the electric hydraulic push rod is connected to a fixed plate, a mounting seat is provided on the top of the fixed plate, a vibrating plate body is installed on the upper surface of the mounting seat, a spiral conveying sheet is provided on the inner wall of the vibrating plate body, and a screening port is provided on one side of the inner wall of the vibrating plate body. The vibrating plate body transports the material through the spiral conveying sheet. During the conveying process of the spiral conveying sheet, the material will pass through the screening port. When the too small material passes through the screening port, the too small material will be discharged through the screening port and the discharge pipe. At the same time, the larger material will continue to be transported through the spiral conveying sheet, and the spiral conveying sheet will discharge the larger material through the discharge channel. In this way, the material can be screened and divided, which can effectively improve the efficiency of the material conveying of the vibrating plate;

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In actual use, an existing vibrating plate for screening and sorting materials has a screening port located on the side of the spiral conveying plate. When the material passes by the screening port from the surface of the spiral conveying plate, only a portion of the small material can enter the screening port, and the other portion of the material may be discharged through the discharge channel together with the large material, resulting in material confusion. Therefore, a more precise structure for material screening is provided to cooperate with the vibrating plate to screen the material. Example

[0032] like Figures 1 to 6 The utility model provides a vibrating plate capable of screening materials.

[0033] Specifically, by Figure 1-3A vibrating plate for screening materials is provided, comprising a vibrating plate 1, a spiral conveying sheet 4, a spiral frame 6 and a screening assembly 2, wherein the spiral conveying sheet 4 is used to convey materials of different sizes, the spiral frame 6 is used to fix the spiral conveying sheet 4, the screening assembly 2 is used to screen different materials on the top of the spiral conveying sheet 4, the screening assembly 2 comprises a first screening plate 201 opened inside the spiral conveying sheet 4, a diverter arc plate 202 is installed on the top of the first screening plate 201, and a second screening plate 20 is installed on the inner wall of the spiral frame 6 3. The second screening plate 203 is located below the first screening plate 201. Both the first screening plate 201 and the second screening plate 203 are located inside the spiral frame 6. A fixed plate 204 is fixedly installed on the top of the diversion arc plate 202. A first arc-shaped limiting plate 205 is installed on the outer wall of the fixed plate 204. A second arc-shaped limiting plate 206 is installed on the side of the fixed plate 204 away from the first arc-shaped limiting plate 205. Both the first arc-shaped limiting plate 205 and the second arc-shaped limiting plate 206 are located above the first screening plate 201.

[0034] The vibration plate 1 uses a pulse electromagnet to make the upper cover of the vibration plate 1 vibrate in the vertical direction, and the inclined spring sheet drives the spiral conveying sheet 4 to make the material in the spiral conveying sheet 4 rotate and vibrate around its vertical axis, so that the material rises along the spiral track of the spiral conveying sheet 4 during the vibration process. When the material shakes to the top of the first screening plate 201, some materials smaller than the pores of the first screening plate 201 will directly fall down to the top of the second screening plate 203, leaving only materials larger than the pores of the first screening plate 201 on the top of the first screening plate 201, and at the same time, the diverter arc plate 202 screens the material on the top of the first screening plate 201;

[0035] Because the distances between the diverter arc plate 202 and the spiral baffles 3 on both sides are different, some larger materials will move to the position with a larger gap, while the position with a smaller gap between the diverter arc plate 202 and the spiral baffle 3 is left for smaller materials. The fixed plate 204 fixes the first arc limiting plate 205 and the second arc limiting plate 206 at the connection between the diverter arc plate 202 and the spiral conveying plate 4, which is convenient for the first arc limiting plate 205 and the second arc limiting plate 206 to limit the top of the materials on both sides, and can limit the stacking height of the materials in the spiral conveying plate 4, thereby controlling the thickness of the material layer.

[0036] Further:

[0037] like Figure 2 and Figure 6 It is shown that there is a gap between the first arc-shaped limit plate 205 and the second arc-shaped limit plate 206 and the first screening plate 201, the distance between the diverter arc plate 202 and one of the inner walls of the spiral frame 6 is smaller than the distance between the diverter arc plate 202 and the other inner wall of the spiral frame 6, and a plurality of guide rods 14 are installed on the top of the spiral conveying plate 4.

[0038] The distances between the diverter arc plate 202 and the spiral baffles 3 on both sides are different, so some larger materials will move to the position with a larger gap, while the position with a smaller gap between the diverter arc plate 202 and the spiral baffle 3 is left for smaller materials to pass through. Multiple guide rods 14 guide the materials before they pass through the diverter arc plate 202, so that larger materials are separated from smaller materials in advance, so that these materials can be screened by the diverter arc plate 202 more quickly when they reach the position of the diverter arc plate 202.

[0039] Further:

[0040] like Figure 1-Figure 4 It is shown that a small material discharge channel 8 is fixedly installed on the outer wall of the second screening plate 203 , and the small material discharge channel 8 is located below the limiting block 9 , and a spiral bottom plate 5 is installed on the inner wall of the spiral frame 6 , and the spiral bottom plate 5 is located below the second screening plate 203 .

[0041] The material screened by the first screening plate 201 falls on the top of the second screening plate 203. When the material on the top of the second screening plate 203 is discharged, it is sent out through the small material discharge channel 8. At the same time, the outlet of the small material discharge channel 8 is separated from the outlet of the large material discharge channel 7 to avoid the material in the large material discharge channel 7 and the material in the small material discharge channel 8 from being mixed again. The spiral bottom plate 5 is used to receive the impurities dropped by the first screening plate 201 and the second screening plate 203, so that the material will not be mixed with impurities after being discharged.

[0042] Further:

[0043] like Figure 4 It is shown that a funnel 10 is connected to the bottom of the spiral bottom plate 5 , a conveying pipe 11 is connected to the bottom of the funnel 10 , and one end of the conveying pipe 11 away from the funnel 10 extends to the outside of the vibration plate 1 .

[0044] When impurities are removed from the outlet of the spiral bottom plate 5, they can directly fall into the interior of the funnel 10, and then the impurities in the funnel 10 are discharged from the outside of the vibrating plate 1 through the conveying pipe 11, avoiding impurities from being left inside the spiral bottom plate 5 and the funnel 10, and facilitating the continuous discharge of impurities from the spiral bottom plate 5. Example

[0045] Further:

[0046] like Figure 1-6 It is shown that a spiral baffle 3 is installed on the top of the spiral frame 6, one end of the spiral baffle 3 is connected to a large material discharge channel 7, and two limit blocks 9 are installed on the inner bottom wall of the large material discharge channel 7.

[0047] The spiral baffle 3 is used to block the material in the spiral conveyor plate 4 to prevent the vibrating material from falling out of the spiral conveyor plate 4. When the material needs to be discharged from the spiral conveyor plate 4, the material is discharged through the large material discharge channel 7, and then the limit blocks 9 fix the two sides of the material to keep the material discharged in the posture required by the customer.

[0048] Further:

[0049] like Figure 4-Figure 5 It is shown that the spiral conveying piece 4 is provided with an arc groove 12 , and two limit plates 13 are installed inside the arc groove 12 . One end of the limit plate 13 away from the spiral conveying piece 4 is connected to the limit block 9 .

[0050] When the material is at the top of the spiral conveyor plate 4, the discharge of the material is messy and irregular. When the material moves to the arc groove 12, it will fall into the arc groove 12, and then the larger end of the material will be clamped by the limiting plates 13 on both sides, so that the rest of the material is suspended inside the arc groove 12, so that the material can be kept neat, and then after the material moves to the inside of the large material discharge channel 7, these materials can still be stuck on the top of the two limiting blocks 9 and then discharged, so that the material maintains a neat direction and angle.

[0051] Working principle:

[0052] The vibration plate 1 uses a pulse electromagnet to make the upper cover of the vibration plate 1 vibrate in the vertical direction, and the inclined spring sheet drives the spiral conveying sheet 4 to make the material in the spiral conveying sheet 4 rotate and vibrate around its vertical axis, so that the material rises along the spiral track of the spiral conveying sheet 4 during the vibration process. When the material shakes to the top of the first screening plate 201, some materials smaller than the pores of the first screening plate 201 will directly fall down to the top of the second screening plate 203, leaving only materials larger than the pores of the first screening plate 201 on the top of the first screening plate 201, and at the same time, the diverter arc plate 202 screens the material on the top of the first screening plate 201;

[0053] Because the distances between the diverter arc plate 202 and the spiral baffles 3 on both sides are different, some larger materials will move to the position with a larger gap, while the position with a smaller gap between the diverter arc plate 202 and the spiral baffle 3 is left for smaller materials. The fixed plate 204 fixes the first arc limiting plate 205 and the second arc limiting plate 206 at the connection between the diverter arc plate 202 and the spiral conveying plate 4, which is convenient for the first arc limiting plate 205 and the second arc limiting plate 206 to limit the top of the materials on both sides, and can limit the stacking height of the materials in the spiral conveying plate 4, thereby controlling the thickness of the material layer.

[0054] The spiral baffle 3 is used to block the material in the spiral conveyor plate 4 to prevent the vibrating material from falling out of the spiral conveyor plate 4. When the material needs to be discharged from the spiral conveyor plate 4, the material is discharged through the large material discharge channel 7, and then the limit blocks 9 fix the two sides of the material to keep the material discharged in the posture required by the customer.

[0055] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
