Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a limiting mechanism for a vibrating screen. Background Technology

[0002] Vibrating screens separate a group of loose materials of different particle sizes into several different grades by passing them through a single or multiple layers of screen surface with uniformly distributed holes. Particles larger than the screen holes remain on the screen surface and are called the oversize material of that screen surface, while particles smaller than the screen holes pass through the screen holes and are called the undersize material of that screen surface. They are widely used in industries such as sand and gravel plants, mines, building materials, chemicals, water conservancy and hydropower, and concrete mixing.

[0003] In the prior art, a vibrating motor drives the box to vibrate, which in turn drives the screening plate to vibrate for screening Chinese herbal medicines. However, this method causes significant damage to the box and reduces its service life. Furthermore, after prolonged use, the screening plate is prone to clogging of the mesh. Moreover, the vibrating motor cannot only vibrate the box; the vibration transmitted to the screening plate cannot dislodge the Chinese herbal medicines from the mesh, thus affecting the screening efficiency. To address the above problems, application number 202320563391.2 discloses a vibrating screen, which includes a base plate. A box is fixedly connected to the upper surface of the base plate. The inner wall of the box is provided with two storage boxes. A first screening plate is installed on the inner wall of one storage box, and a second screening plate is installed on the inner wall of the other storage box. Two sets of symmetrical limiting mechanisms are provided on the outer surface of both storage boxes. A guide block is fixedly connected to the inner wall of the box. A discharge port is opened on the outer surface of the base plate, and a storage box is located below the base plate.

[0004] However, a thorough reading of the aforementioned patent documents revealed the following shortcomings: during use, at least two of the limiting rods on the same side need to be moved simultaneously for disassembly, requiring two workers to operate, resulting in low work efficiency, inconvenient installation, and a cumbersome installation process that wastes manpower and time, leaving room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting mechanism for a vibrating screen, which allows workers to assemble and disassemble the three screens without the need for tools.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a limiting mechanism for a vibrating screen, comprising a vibrating screen body, a screening screen, and a limiting mechanism;

[0007] The vibrating screen body has three mounting slots, and each of the three mounting slots has a slidably connected screening screen. One end of each of the three screening screens is fixedly connected to a hook. The vibrating screen body has three limiting mechanisms, which are respectively connected to the three hooks. First, the raw material to be screened is fed into the vibrating screen body through the feed inlet. Then, the vibration motor on the vibrating screen body is started, so that the vibrating screen body works. At the same time, the vibrating screen body drives the three screening screens to vibrate synchronously, thereby achieving the effect of grading and screening the raw material. Afterward, the screened raw material is discharged through the discharge port at the bottom of the vibrating screen body.

[0008] The limiting mechanism includes a fixed block, a movable plate, a rotating shaft, a second hook, a threaded rod, a limiting nut, and a rotating plate. Three fixed blocks are fixedly connected to one side of the vibrating screen body. A movable plate is slidably connected to the fixed block. A rotating shaft is fixedly connected to one end of the movable plate. A second hook is rotatably connected to the rotating shaft. The second hook engages with the corresponding first hook. Through the cooperative design between the vibrating screen body, the screening screen, the first hook, and the limiting mechanism, only one worker is needed to disassemble and assemble the three screening screens. Moreover, the three screening screens can be quickly installed and disassembled without the aid of tools.

[0009] A further feature of this invention is that the movable plate is slidably connected to the vibrating screen body, and the second hook is slidably connected to the vibrating screen body. During the process of the threaded rod driving the second hook to move to the right through the transmission of the movable plate and the rotating shaft, the second hook acts on the vibrating screen body, thereby causing the second hook to rotate at a certain angle on the rotating shaft and move into the corresponding sliding groove, thus achieving the effect of facilitating the connection between the second hook and the corresponding first hook.

[0010] A further feature of this invention is that a threaded rod is rotatably connected to one end of the movable plate, and the threaded rod is threadedly connected to the fixed block. By rotating the threaded rod through the rotating plate, the threaded rod and the fixed block are threadedly driven and rotate on the movable plate, and one end of the threaded rod pushes the movable plate to slide within the sliding groove one on the corresponding fixed block and the sliding groove two on the vibrating screen body.

[0011] A further feature of this invention is that a limiting nut is threadedly connected to the threaded rod, and the limiting nut abuts against the fixing block. By rotating the limiting nut and causing it to abut against the fixing block, the limiting nut can effectively limit the threaded rod and prevent it from loosening.

[0012] A further feature of this invention is that a rotating plate is fixedly connected to one end of the threaded rod, which facilitates the rotation of the threaded rod.

[0013] A further feature of this invention is that each of the three fixed blocks is provided with a sliding groove, the three movable plates are slidably connected within the three sliding grooves, and a bearing is fixedly sleeved on one end of the threaded rod. The outer wall of the bearing is fixedly connected to the movable plate to facilitate the rotation of the threaded rod.

[0014] A further feature of this invention is that the vibrating screen body has three sliding grooves II, which correspond to the three sliding grooves I respectively. The three moving plates and hooks II slide within the three sliding grooves II respectively. The three sliding grooves II can limit the position of the three hooks II.

[0015] A further feature of this invention is that three guide plates are fixedly connected inside the vibrating screen body, and the three guide plates are respectively connected to the three hooks and the screen mesh. The three guide plates are all adapted to the three screen meshes for guiding the raw materials.

[0016] A further feature of this invention is that protrusions are fixedly connected to both sides of each of the three screening screens, and the six protrusions slide within the three mounting slots respectively. The six protrusions further limit the position of the three screening screens. A handle is fixedly connected to one side of each of the three screening screens to facilitate pulling the three screening screens.

[0017] A further feature of this invention is that the top of the vibrating screen body is provided with a feed inlet for conveying the raw materials to be screened into the vibrating screen body, and the bottom of the vibrating screen body is provided with a discharge outlet for discharging the screened raw materials.

[0018] The beneficial effects of this utility model are: through the cooperative design between the vibrating screen body, the screening screen, the hook and the limiting mechanism, only one worker is needed to disassemble and assemble the three screening screens, and the three screening screens can be quickly installed and disassembled without the aid of tools.

[0027] Reference Figure 1-4 A limiting mechanism for a vibrating screen includes a vibrating screen body 1, a screening screen 3, and a limiting mechanism 5;

[0028] The vibrating screen body 1 has three mounting slots 2, and each of the three mounting slots 2 has a slidably connected screen 3. Each of the three screens 3 has a hook 4 fixedly connected to one end. The vibrating screen body 1 has three limiting mechanisms 5, which are respectively connected to the three hooks 4. First, the raw material to be screened is fed into the vibrating screen body 1 through the feed inlet 7. Then, the vibration motor on the vibrating screen body 1 is started, so that the vibrating screen body 1 works. At the same time, the vibrating screen body 1 drives the three screens 3 to vibrate synchronously, thereby achieving the effect of classifying and screening the raw material. After that, the screened raw material is discharged through the discharge port at the bottom of the vibrating screen body 1.

[0029] The limiting mechanism 5 includes a fixed block 51, a movable plate 52, a rotating shaft 53, a second hook 54, a threaded rod 55, a limiting nut 56, and a rotating plate 57. Three fixed blocks 51 are fixedly connected to one side of the vibrating screen body 1. A movable plate 52 is slidably connected to the fixed block 51. A rotating shaft 53 is fixedly connected to one end of the movable plate 52. A second hook 54 is rotatably connected to the rotating shaft 53. The second hook 54 is engaged with the corresponding first hook 4. Through the cooperative design between the vibrating screen body 1, the screening screen 3, the first hook 4, and the limiting mechanism, only one worker is needed to disassemble and assemble the three screening screens 3. Moreover, the three screening screens 3 can be quickly installed and disassembled without the aid of tools.

[0030] See attached document Figure 2 The movable plate 52 is slidably connected to the vibrating screen body 1, and the second hook 54 is slidably connected to the vibrating screen body 1. During the process of the threaded rod 55 driving the second hook 54 to move to the right through the transmission of the movable plate 52 and the rotating shaft 53, the second hook 54 interacts with the vibrating screen body 1, thereby causing the second hook 54 to rotate at a certain angle on the rotating shaft 53 and move the second hook 54 into the corresponding sliding groove 9, thereby achieving the effect of facilitating the connection between the second hook 54 and the corresponding first hook 4.

[0031] See attached document Figure 3-4 A threaded rod 55 is rotatably connected to one end of the movable plate 52. The threaded rod 55 is threadedly connected to the fixed block 51. By rotating the rotating plate 57, the threaded rod 55 is threadedly driven to the fixed block 51 and rotates on the movable plate 52. One end of the threaded rod 55 pushes the movable plate 52 to slide in the corresponding sliding groove 1 on the fixed block 51 and the sliding groove 2 9 on the vibrating screen body 1. A limit nut 56 is threadedly connected to the threaded rod 55. The limit nut 56 abuts against the fixed block 51. By rotating the limit nut 56, the limit nut 56 abuts against the fixed block 51. At this time, the limit nut 56 can limit the threaded rod 55 and prevent it from loosening. One end of the threaded rod 55 is fixedly connected to the rotating plate 57 to facilitate the rotation of the threaded rod 55.

[0032] See attached document Figure 2-4 Each of the three fixed blocks 51 has a sliding groove 1. The three movable plates 52 are slidably connected in the three sliding grooves 1 respectively. One end of the threaded rod 55 is fixedly fitted with a bearing 1. The outer wall of the bearing 1 is fixedly connected to the movable plate 52 to facilitate the rotation of the threaded rod 55. The vibrating screen body 1 has three sliding grooves 2 9, which are respectively corresponding to the three sliding grooves 1. The three movable plates 52 and the hooks 2 54 slide in the three sliding grooves 2 9 respectively. The three sliding grooves 2 9 can achieve the effect of limiting the three hooks 2 54.

[0033] See attached document Figure 2 The vibrating screen body 1 has three guide plates 6 fixedly connected inside. The three guide plates 6 are respectively connected to three hooks 4 and screens 3. The three guide plates 6 are all adapted to the three screens 3 and are used to guide the raw materials. The three screens 3 have protrusions fixedly connected to both sides. The six protrusions slide in the three mounting grooves 2 respectively. The six protrusions further limit the position of the three screens 3. The three screens 3 have handles 8 fixedly connected to one side for easy pulling. The top of the vibrating screen body 1 is provided with a feed port 7 for conveying the raw materials to be screened into the vibrating screen body 1. The bottom of the vibrating screen body 1 is provided with a discharge port for discharging the screened raw materials.

[0034] Working principle: When in use, the raw materials to be screened are first fed into the vibrating screen body 1 through the feed inlet 7. Then, the vibration motor on the vibrating screen body 1 is started, so that the vibrating screen body 1 works. At the same time, the vibrating screen body 1 drives the three screening screens 3 to vibrate synchronously, thereby achieving the effect of classifying and screening the raw materials. Afterwards, the screened raw materials are discharged through the discharge port at the bottom of the vibrating screen body 1.

[0035] When it is necessary to disassemble the three screening screens 3, the threaded rod 55 is rotated by the rotating plate 57, so that the threaded rod 55 and the fixed block 51 are threadedly driven and rotate on the moving plate 52. One end of the threaded rod 55 pushes the moving plate 52 to slide to the left in the sliding groove 1 on the corresponding fixed block 51 and the sliding groove 2 9 on the vibrating screen body 1. At the same time, the moving plate 52 moves synchronously through the transmission belt of the rotating shaft 53 and the hook 2 54, so that the hook 2 54 is disengaged from the corresponding sliding groove 2 9. Under the action of gravity, the hook 2 54 rotates downward on the rotating shaft 53 at a certain angle, so that the hook 2 54 is disengaged from the corresponding hook 1 4, thereby releasing the limit on the hook 1 4 and releasing the limit on the corresponding screening screen 3. Then, the handle 8 on the screening screen 3 is pulled to the left, so that the screening screen 3 is disengaged from the corresponding mounting groove 2 on the vibrating screen body 1, thereby achieving the effect of quick disassembly of the screening screen 3.

[0036] When installing the three screening screens 3, first insert the three screening screens 3 into the three mounting slots 2 respectively, and make the hook 4 on the screening screen 3 contact the vibrating screen body 1. Then, rotate the corresponding rotating plate 57 in the opposite direction, so that the threaded rod 55 and the fixed block 51 are threadedly driven. The threaded rod 55 drives the hook 54 to move to the right through the transmission of the moving plate 52 and the rotating shaft 53. During this process, the hook 54 interacts with the vibrating screen body 1, so that the hook 54 rotates a certain angle on the rotating shaft 53 and moves into the corresponding sliding groove 9, so that the hook 4 corresponding to the hook 54 is engaged, thereby limiting the hook 4 and limiting the screening screen 3, thus achieving the effect of quick installation of the screening screen 3.

[0037] At the same time, under the pulling force of the threaded rod 55, the second hook 54 and the vibrating screen body 1 reinforce the first hook 4, thereby further limiting the position of the first hook 4 and improving stability;

[0038] Then, rotate the limiting nut 56 until it abuts against the fixing block 51. At this time, the limiting nut 56 can limit the threaded rod 55 and prevent it from loosening.

[0039] The technological advancement of this invention compared to the prior art is that, through the cooperation of various components, only one worker is needed to assemble and disassemble the three screening nets 3, and the three screening nets 3 can be quickly installed and disassembled without the aid of tools. This not only improves convenience and efficiency but also reduces labor and time costs, making it more practical.
