Utility Model Content

[0005] To improve the ease of use of vibrating screens, this application provides a vibrating screen device that facilitates screen replacement.

[0006] This application provides a vibrating screen device that facilitates screen replacement, employing the following technical solution:

[0007] A vibrating screen device for easy screen replacement includes a support frame, characterized in that: a screen box is provided at the upper end of the support frame, a feed inlet is provided at the upper end of the screen box, a vibrating motor is fixed at the lower end of the screen box, the vibrating motor is used to drive the screen box to vibrate, a shock-absorbing elastic element is fixed between the support frame and the screen box, the shock-absorbing elastic element is used to reduce the impact of the screen box on the support frame, two screens are provided inside the screen box, two disassembly ports are provided on the side of the screen box near the feed inlet, the disassembly ports correspond one-to-one with the screens, the screens pass through the disassembly ports laterally and slide in connection with the screen box, the screens near the feed inlet... Two movable plates are provided on one side, located at both ends of the screen. Both movable plates are slidably connected to the screen along the width of the screen. A groove is provided at the upper end of the screen, and a connecting rod is provided in the groove. The connecting rod is fixedly connected to the movable plate. A fixing component is provided on the outside of the screen body to reduce the probability of the movable plates moving when the screen box vibrates. A connecting component is provided between the screens to connect them together. Several discharge ports are provided at the end of the screen box away from the feed inlet. Each discharge port corresponds to a screen, and the screened material flows out from the discharge port.

[0008] By adopting the above technical solution, the material enters the screen box from the feed inlet, the vibrating motor starts and drives the screen box to vibrate, and the material passes through the screen from top to bottom for screening. After screening, the material is discharged from different outlets. When the screen needs to be replaced, the connecting rod moves horizontally, and the moving rod moves the moving plate, which separates the moving plate from the fixed part. The two screens are then removed at the same time through the connecting part, making the installation and disassembly of the screen more convenient and improving the ease of use of the vibrating screen.

[0009] Optionally, the fixing component includes a fixing block, which is fixed to the outside of the screen box. The fixing block has a groove, and the moving plate is inserted into the groove and engaged with the inner wall of the groove. The moving plate is ferromagnetic, and a strong magnet is provided in the groove to attract the moving plate.

[0010] By adopting the above technical solution, the connecting rod moves laterally, which in turn moves the moving plate, allowing the moving plate to be inserted into the groove and engaged with the inner wall of the groove. This reduces the probability of the moving plate shifting during the vibration of the screen box. The strong magnet holds the moving plate in place, further reducing the probability of the moving plate shifting due to accidents, thus ensuring the stability of the vibrating screen device.

[0011] Optionally, the connector includes a vertical rod, a connecting plate, and a pull rod. The vertical rod is fixed to the side of the screen near the connecting rod. The two connecting plates pass through the corresponding vertical rods respectively, and the connecting plates are slidably connected to the vertical rods along the length of the vertical rods. The pull rod is located at the end of the connecting plate away from the vertical rod, and the pull rod is fixedly connected to the two connecting plates, and the pull rod slides along the circumference of the vertical rod.

[0012] By adopting the above technical solution, pulling the pull rod moves the connecting plate, which in turn moves the vertical rod, which in turn moves the two screens together, making the screens easy to disassemble and install. When it is necessary to replace any one of the screens, the pull rod is moved vertically, which moves the connecting plate, separating the connecting plate from the vertical rod, thus improving the flexibility of the vibrating screen device.

[0013] Optionally, a number of fixing plates are fixed inside the screen box. The fixing plates are located on both sides of the screen box and at the lower end of the screen mesh, where they are tightly fitted.

[0014] By adopting the above technical solution, when installing the screen, the fixing plate guides the screen, making the installation of the screen easier. At the same time, during vibration, the fixing plate supports the screen.

[0015] Optionally, the outside of the screen box is provided with two fixing rods that pass through the corresponding screen mesh. The upper end of the fixing rod is provided with an insert rod with an arc-shaped groove that fits the surface of the fixing rod. One end of the insert rod is provided with a rotating part that is threadedly connected to the insert rod.

[0016] By adopting the above technical solution, rotating the rotating component limits the insertion rod of the screen box. The rotation of the rotating component drives the insertion rod to move laterally, so that the arc groove locks the fixed rod, reducing the probability of the fixed rod moving. This further reduces the probability of the screen mesh shifting when the vibrating motor vibrates the screen box, thus improving the stability of the vibrating screen.

[0017] Optionally, the screen box is equipped with two brush rods, each corresponding to a screen mesh. The upper end of the brush rod is equipped with a cleaning component for cleaning the material on the screen mesh. The two brush rods are located at the lower end of their respective screen meshes, and the lower end of the brush rod is equipped with a moving component for moving the brush rod.

[0018] By adopting the above technical solution, the moving component drives the brush rod to move along the length of the screen, so that the brush rod cleans the material on the surface of the screen, reduces the probability of screen blockage, and improves the ease of use of the vibrating screen device.

[0019] Optionally, the moving component includes a lead screw, a motor, and a drive block. The motor is fixed to the outside of the screen box, the lead screw is coaxially fixed to the motor output shaft, and the lead screw is arranged along the length of the screen box. The lead screw passes through the drive block and is threadedly connected to the drive block, and the upper end of the drive block is fixedly connected to the brush rod.

[0020] By adopting the above technical solution, the motor is started, which drives the lead screw to rotate. The brush rod limits the drive block, and the rotation of the lead screw drives the drive block to move along the length of the screen. The drive block moves along the length of the screen box, which in turn drives the brush rod to move along the length of the screen, so that the brush rod cleans the surface of the screen and reduces the probability of screen blockage.

[0021] Optionally, the cleaning component includes protrusions and elastic elements. Several protrusions are arranged along the axial direction of the brush rod and are in close contact with the screen. The elastic elements are fixed between the protrusions and the brush rod and are used to drive the protrusions closer to the screen.

[0022] By adopting the above technical solution, the protrusions fit tightly against the screen, lifting up the material remaining on the screen, reducing the probability of material residue on the screen, improving the cleanliness of the screen, and the elastic element keeps the protrusions in contact with the screen under pressure, ensuring the cleaning effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When it is necessary to replace the screen, move the connecting rod horizontally. The movement of the connecting rod will drive the moving plate to move, so that the moving plate is separated from the fixed part. The two screens can be removed at the same time through the connecting part, making the installation and disassembly of the screen more convenient and improving the convenience of using the vibrating screen.

[0025] 2. Rotating the rotating component limits the insertion rod of the screen box. The rotation of the rotating component drives the insertion rod to move laterally, so that the arc groove locks the fixed rod, reducing the probability of the fixed rod moving. This further reduces the probability of the screen mesh shifting when the vibrating motor vibrates the screen box, thus improving the stability of the vibrating screen.

[0026] 3. The protrusions fit tightly against the screen, lifting up any residual material on the screen, reducing the probability of material residue on the screen and improving the cleanliness of the screen. Attached Figure Description

Detailed Implementation

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] This application discloses a vibrating screen device that facilitates screen replacement. Example

[0036] Reference Figure 1 and Figure 2 A vibrating screen device with easy screen replacement includes a support 1, a screen box 11 at the upper end of the support 1, the support 1 supporting the screen box 11, a feed inlet 112 at the upper end of the screen box 11 through which material enters the screen box 11, a vibrating motor 12 fixed at the lower end of the screen box 11, the vibrating motor 12 driving the screen box 11 to vibrate when started, and a shock-absorbing elastic element 13 fixed between the support 1 and the screen box 11, the shock-absorbing elastic element 13 reducing the impact of the screen box 11 on the support 1 when the screen box 11 vibrates, thus improving the performance of the vibrating screen device. For durability, the screen box 11 is equipped with two screens 111. Two disassembly ports are opened on the side of the screen box 11 near the feed inlet 112. The disassembly ports correspond one-to-one with the screens 111. The screens 111 pass through the disassembly ports in the transverse direction and slide to connect with the screen box 11. After the material enters the screen box 11, it passes through the two screens 111 for screening at one time. Several discharge ports 113 are opened at the end of the screen box 11 away from the feed inlet 112. The screened material flows out from the discharge ports 113, so that the material can be screened in multiple stages at one time, which improves the convenience of using the vibrating screen.

[0037] Reference Figure 2 and Figure 3Two sliding grooves 1112 are provided on the side of the screen 111 near the feed inlet 112. The two sliding grooves 1112 are located at both ends of the screen 111. A connecting rod 1113 is provided in the sliding groove 1112. A movable plate 1111 is fixedly provided at the lower end of the connecting rod 1113. The movable plate 1111 is slidably connected to the screen 111 along the width direction of the screen 111. A fixing block 114 is fixedly provided on the outside of the screen box 11. A groove 1141 is provided in the fixing block 114. The movable plate 1111 is inserted into the groove 1141 and is engaged with the inner wall of the groove 1141, which reduces the probability of the movable plate 1111 shifting during the vibration of the screen box 11. A strong magnet 1142 is provided in the groove 1141. The movable plate 1111 is ferromagnetic. After the movable plate 1111 enters the groove 1141, the strong magnet 1142 attracts the movable plate 1111, further reducing the probability of the movable plate 1111 shifting and ensuring the stability of the equipment operation. The connecting rod 1113 is moved along the length of the chute 1112. The movement of the connecting rod 1113 drives the moving plate 1111 to move, so that the moving plate 1111 is separated from the fixed block 114, and the screen 111 is taken out from the screen box 11, which improves the convenience of using the vibrating screen.

[0038] Reference Figure 2 Several fixing plates 115 are fixed inside the screen box 11. The fixing plates 115 are located on both sides of the screen box 11 and are located at the lower end of the screen 111, and are tightly fitted with the screen 111. When installing the screen 111, the fixing plates 115 guide the screen 111 to facilitate the installation of the screen 111. At the same time, during vibration, the fixing plates 115 support the screen 111.

[0039] Reference Figure 4 A connector is provided between the two screens 111. The connector includes a vertical rod 1114, a connecting plate 1115, and a pull rod 1116. The vertical rod 1114 is fixed to the side of the screen 111 near the connecting rod 1113. The two connecting plates 1115 pass through their respective vertical rods 1114 and are slidably connected to the vertical rods 1114 along their length. The pull rod 1116 is located at the end of the connecting plate 1115 away from the vertical rod 1114 and is fixedly connected to the two connecting plates 1115. Pulling the lever 1116 moves the connecting plate 1115, which in turn moves the vertical rod 1114. The vertical rod 1114 then moves the two screens 111 together, making it easy to disassemble and install the two screens 111 simultaneously. When it is necessary to replace either screen 111, the lever 1116 is moved vertically, which moves the connecting plate 1115, separating the connecting plate 1115 from the vertical rod 1114 and improving the flexibility of the vibrating screen device.

[0040] Reference Figure 5The screen box 11 is equipped with two sets of moving components, each including a lead screw 1161, a motor 116, and a drive block 1162. The motor 116 is fixed to the outside of the screen box 11, and the lead screw 1161 is located at the lower end of the corresponding screen 111. The lead screw 1161 is arranged along the length of the screen box 11, and is coaxially fixed with the output shaft of the motor 116. When the motor 116 starts, it drives the lead screw 1161 to rotate. The drive block 1162 is threadedly connected to the lead screw 1161. A brush rod 1163 is fixedly connected to the upper end of the drive block 1162, and the brush rod 1163 limits the movement of the drive block 1162. The rotation of the lead screw 1161 drives the drive block 1162 to rotate along the screen box 1161. The screen 111 moves along its length, and the drive block 1162 moves along the length of the screen 111, causing the brush rod 1163 to move along the length of the screen 111. The brush rod 1163 is provided with several protrusions 1164 along its axial direction. The protrusions 1164 are in close contact with the screen 111. The movement of the brush rod 1163 along the length of the screen 111 causes the protrusions 1164 on the brush rod 1163 to lift up the material remaining on the surface of the screen 111, reducing the probability of the screen 111 clogging. An elastic element 1165 is provided between the protrusions 1164 and the brush rod 1163, so that pressure is generated when the protrusions 1164 come into contact with the screen 111, improving the cleaning effect of the screen 111.

[0041] Reference Figure 6 Two fixing rods 1117 are provided on the side of the screen box 11 away from the feed inlet 112. The two fixing rods 1117 pass through the corresponding screens 111. The upper end of the fixing rods 1117 is provided with an insert rod 1119. The insert rod 1119 has an arc-shaped groove 1118. The arc-shaped groove 1118 fits the surface of the fixing rod 1117. One end of the insert rod 1119 is provided with a rotating part. The rotating part is threadedly connected to the insert rod 1119. After the screen 111 enters the screen box 11, the rotating part is rotated. The screen box 11 limits the insertion rod 1119. The rotation of the rotating part drives the insertion rod 1119 to move laterally, so that the arc-shaped groove 1118 locks the fixing rod 1117. This reduces the probability of the screen 111 shifting when the vibrating motor 116 vibrates the screen box 11, and improves the stability of the vibrating screen. When the screen 111 needs to be replaced, the rotating part is rotated to remove the fixing rod 1117 from the screen 111, which improves the convenience of using the vibrating screen.

[0042] The implementation principle of a vibrating screen device for easy screen replacement according to an embodiment of this application is as follows: Material enters from the feed inlet 112 and is then screened by two screens 111. After screening, the material flows out from the discharge outlet 113. When it is necessary to replace the screens 111, the rotating component is rotated to separate the fixed rod 1117 from the screens 111. The connecting rod 1113 is slid laterally, and the movement of the connecting rod 1113 drives the moving plate 1111 to move, so that the moving plate 1111 is separated from the fixed block 114. The pull rod 1116 is pulled laterally, and the movement of the pull rod 1116 drives the connecting plate 1115 to move. The movement of the connecting plate 1115 drives the pull rod 1116 to move, so that the two screens 111 are separated from the screen box 11 at the same time, further realizing the replacement of the screens 111 and improving the portability of the vibrating screen.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
