Description

Technical Field

[0001] This utility model relates to the field of reciprocating vibrating screen technology, and in particular to an ultra-quiet reciprocating vibrating screen. Background Technology

[0002] A reciprocating vibrating screen is a device that uses reciprocating linear motion to screen materials. Its screen surface vibrates in the front and back directions through an excitation device, causing the material to jump, slide or throw on the screen surface, thereby achieving the purpose of grading according to particle size.

[0003] Existing reciprocating vibrating screens have relatively complex structures, and the screen body and base are usually rigidly connected or simply supported by a single layer of springs, lacking a multi-stage buffering mechanism. When the screen body reciprocates, the vertical vibration component is not effectively suppressed, resulting in frequent collisions between the bottom of the screen body and the base, causing instantaneous impact noise and exacerbating the harshness of the working environment of the vibrating screen. To address this problem, the inventors designed an ultra-quiet reciprocating vibrating screen. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-quiet reciprocating vibrating screen, which has the advantages of simple structure, reasonable design, and avoidance of collision between screen body and base, which would cause large noise, by using connecting parts instead of transmission springs, thus maintaining the quiet operation of the device and solving the problems mentioned in the above technical background.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-5As shown, this embodiment is an ultra-quiet reciprocating vibrating screen, including a base 1, a connecting frame 2 set on the top of the base 1, a vibrating motor 3 distributed on the outer surfaces of both ends of the connecting frame 2, and a connecting shaft 4 connected to the inner side of the vibrating motor 3. The connecting frame 2 is provided with a connector 5, which includes a second gasket 51, a mounting plate 52, a third gasket 53, and a fixing plate 54.

[0028] The base 1 is used to fix the device in the required position. The connecting frame 2 serves as the mounting frame for the vibrating motor 3 and the connecting piece 5, and is used to transmit the vibration force to the screen body 6. The vibrating motor 3 provides the excitation force to drive the screen body 6 to reciprocate. The connecting shaft 4 synchronizes the vibration frequency and direction of the vibrating motors 3 on both sides to ensure that the screen body 6 is subjected to uniform force and improves the screening stability.

[0029] The second gasket 51 is fixed on the inner surface of the connecting frame 2. There are eight sets of the second gasket 51. The mounting plate 52 is set on the outside of both sides of any set of the second gasket 51. The third gasket 53 is set on the inside of the top of the mounting plate 52. The fixing plate 54 is fixed on the outer surface of the third gasket 53.

[0030] The second gasket 51 isolates the mounting plate 52 from direct contact with other metal parts, reducing frictional noise during vibration transmission. The mounting plate 52 bears the excitation force of the vibration motor 3 and transmits it to the screen body 6. The third gasket 53 further buffers the vibration between the mounting plate 52 and the fixing plate 54, limiting the amplitude height of the screen body 6. The fixing plate 54 fixes the screen body 6 to the connector 5, limiting its range of motion and preventing collision with the base 1.

[0031] Furthermore, a screen body 6 is provided on the top of the connector 5, and a sealing cover 7 is snapped onto the top of the screen body 6. An inlet 8 is provided inside one side of the sealing cover 7, and an outlet 9 is provided on the other side of the screen body 6.

[0032] The screen body 6 is used to screen materials. The sealing cover 7 seals the top of the screen body 6 to prevent dust from leaking out. The feed inlet 8 guides the material into the screen body 6, and the discharge outlet 9 discharges the screened material to achieve continuous operation.

[0033] Furthermore, the base 1 includes a support column 11, a support plate 12, a connecting plate 13, and a first gasket 14; there are four sets of support columns 11, the support plate 12 is fixed to the top of the support column 11, the connecting plate 13 is fixed to the upper surfaces on both sides of the support plate 12, the first gasket 14 is fixed to the upper surface of the connecting plate 13, there are four sets of first gaskets 14, and the upper surface of any set of first gaskets 14 is fixed to the lower surface of the connecting frame 2;

[0034] The support column 11 bears the weight of the entire equipment and provides basic support. The support plate 12 connects the support column 11 and the connecting plate 13 to enhance structural stability. The connecting plate 13 is used to fix the first gasket 14 and provide an installation surface for the connecting frame 2. The first gasket 14 buffers the vibration transmission between the connecting frame 2 and the base 1, reducing noise and structural wear.

[0035] Furthermore, the sieve body 6 includes a first sieve 61, a second sieve 62, a third sieve 63, a hook 64, a first buckle 65, and a support frame 66; the first sieve 61, the second sieve 62, and the third sieve 63 are disposed inside the support frame 66, the second sieve 62 is located on the other side of the first sieve 61, the third sieve 63 is located at the bottom of the second sieve 62, the hook 64 is fixed on the other side of the upper surface of the first sieve 61, the second sieve 62, and the third sieve 63, the first buckle 65 is snapped inside the hook 64, and the surface of the first buckle 65 is fixed to the surface of the support frame 66, and the outer surfaces at both ends of the support frame 66 are connected to the fixing plate 54;

[0036] The first screen 61, the second screen 62 and the third screen 63 are used to screen materials in multiple stages according to particle size. The hook 64 is used to cooperate with the first buckle 65 to fix the position of the screen and facilitate quick disassembly and replacement. The support frame 66 carries the screen and is connected to the connector 5 through the fixing plate 54 to transmit vibration.

[0037] Furthermore, connecting hooks 71 are fixed on the outer surfaces of both ends of the sealing cover 7. The connecting hooks 71 are evenly distributed. The second buckle 72 is snapped into the inside of the connecting hook 71, and the outer surface of the second buckle 72 is fixed to the outer surface of the support frame 66.

[0038] The connecting hook 71 is used to connect with the second buckle 72, thereby enabling the removal and installation of the sealing cover 7.

[0039] Working principle: When the vibrating screen starts working, the material is conveyed into the screen body 6 through the feed port 8. The two sets of vibrating motors 3 are connected together through the connecting shaft 4, so that the vibrating motors 3 apply vibration force to the screen body 6 more evenly and stably. Since the second shim 51 and the third shim 53 connect the mounting plate 52 together, when the connecting part 5 transmits the vibration force, it can not only avoid the mounting plate 52 from contacting the metal parts and generating noise, but also limit the screen body 6 to a certain height, avoiding the bottom of the screen body 6 from colliding with the base 1 and generating noise. With the design of the first screen 61, the second screen 62 and the third screen 63, the material will be graded and screened, and finally discharged through the discharge port 9.
