Description

Technical Field

[0001] This utility model relates to the field of screening mechanism technology, specifically to a screening mechanism for a gear-type screening machine. Background Technology

[0002] A screening machine is a mechanical device that uses a screen or screen plate to classify, separate, or filter materials. It separates large particles from small particles by intercepting solid particles through the screen.

[0003] In existing technologies, the screening screen of gear screening machines is mostly an integrated design. If a part is damaged, the entire machine needs to be disassembled and repaired, which greatly increases labor costs. When the screen surface is blocked by material, manual entry into the equipment is required for cleaning, which poses a safety hazard. Therefore, a screening mechanism for a gear screening machine is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening mechanism for a gear-type screening machine, which has the advantage of being able to be repaired and replaced without disassembling the entire machine, thus solving the problem of increased time costs caused by the need to disassemble the entire machine's screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening mechanism for a gear-type screening machine, comprising a mounting base, the mounting base comprising a support plate, a driving assembly disposed on the support plate, the driving assembly comprising a mounting cylinder disposed on the support plate, a telescopic assembly disposed on the mounting cylinder, the telescopic assembly comprising a turntable, the turntable having U-shaped grooves distributed circumferentially, and a movable telescopic frame disposed inside the U-shaped grooves.

[0006] Furthermore, the telescopic frame is equipped with a detachable screen, and the telescopic components and the mounting cylinder are symmetrically arranged on both sides of the screen.

[0007] Furthermore, the telescopic frame is restricted within the U-shaped groove by setting a limiting block, the limiting block is provided with a movable block, the movable block is fixedly connected to a frame, the telescopic frame includes a fixed block provided on the mounting cylinder, and the movable block is disposed inside the fixed block and moves.

[0008] Furthermore, the mounting base is provided with a mounting plate, and the mounting plate is provided with a transmission assembly. The transmission assembly includes a first motor mounted on the mounting plate, a drive wheel mounted on the first motor, a belt mounted on the drive wheel, a transmission wheel mounted on the belt, and a connecting shaft mounted on the transmission wheel.

[0009] Furthermore, the drive assembly includes a second motor fixedly connected to the mounting plate, the second motor being provided with a gear, and the mounting cylinder engaging with the gear via a gear ring.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: The screening mechanism of this gear-type screening machine features a telescopic component. When a single screen needs to be disassembled or repaired, the turntable on the telescopic component rotates, causing the limiting block to rotate along the U-shaped groove. This, in turn, pushes the moving block to slide within the fixed block, causing the sliding block to pull the screen outward. If a screen is damaged, that screen can be disassembled individually, avoiding the hassle of cleaning the entire machine. Simultaneously, if the screen is clogged, the telescopic component can be used to open the screen and clean the individual screen. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please see Figure 3-5The screening mechanism of a gear-type screening machine in this embodiment includes a mounting base 1, which includes a support plate 11. A drive assembly 4 is provided on the support plate 11. The drive assembly 4 includes a mounting cylinder 44 provided on the support plate 11. A telescopic assembly 3 is provided on the mounting cylinder 44. The telescopic assembly 3 includes a turntable 31. U-shaped grooves 32 are distributed circumferentially on the turntable 31. A movable telescopic frame 33 is provided inside the U-shaped grooves 32. A detachable screen 335 is provided on the telescopic frame 33. The telescopic assembly 3 and the mounting cylinder 44 are symmetrically arranged on both sides of the screen 335. The telescopic frame 33 is restricted within the U-shaped groove 32 by a limiting block 331. A moving block 332 is provided on the limiting block 331. A frame 334 is fixedly connected to the moving block 332. The telescopic frame 33 includes a fixing block 333 provided on the mounting cylinder 44. The moving block 332 moves inside the fixing block 333.

[0015] As a preferred technical solution in this embodiment: To achieve the disassembly effect, the limiting block 331 adopts a cylindrical structure design, and its outer diameter forms a clearance fit with the arc groove diameter of the U-shaped groove 32. When the turntable 31 on the telescopic component 3 rotates, the limiting block 331 rotates synchronously along the U-shaped groove 32, thereby driving the movable block 332 fixedly connected to it to slide on the fixed block 333. A frame 334 is connected to one side of the movable block 332. Pushing the frame 334 to open outward, the screen 335 opens outward along with the frame 334. Since the screen 335 adopts a detachable design, when a part of the screen 335 is damaged, the screen 335 can be opened through the telescopic component 3, and the damaged part of the screen 335 can be directly removed for repair without replacing the whole screen; at the same time, if the screen 335 is clogged inside, the screen 335 can also be opened through the telescopic component 3 to quickly clear the clogged material.

[0016] Example 2: Please see Figure 1-2 In this embodiment, a gear-type screening machine has a screening mechanism with a mounting base 1 having a mounting plate 12 and a transmission assembly 2 on the mounting plate 12. The transmission assembly 2 includes a first motor 21 mounted on the mounting plate 12, a drive wheel 22 mounted on the first motor 12, a belt 23 mounted on the drive wheel 22, a transmission wheel 24 mounted on the belt 23, and a connecting shaft 25 mounted on the transmission wheel 24.

[0017] As a preferred technical solution in this embodiment: to achieve the control effect of the telescopic component, the first motor 21 is mounted on the mounting plate 12, which is mounted on the mounting base 1. When the first motor 21 rotates, it drives the drive wheel 22 connected to it to rotate. The drive wheel 22 drives the transmission wheel 24 to rotate through the belt 23. The transmission wheel 24 is provided with a connecting shaft 25, which is connected to the telescopic component 3, thereby driving the turntable 31 on the telescopic component 3 to rotate. The opening and closing of the telescopic component 3 is controlled by the rotation of the turntable 31.

[0018] Example 3: Please see Figure 6 The drive assembly 4 includes a second motor 41 fixedly connected to the mounting plate 12. The second motor 41 is provided with a gear 42. The mounting cylinder 44 meshes with the gear 42 through a gear ring 43.

[0019] As a preferred technical solution in this embodiment: to achieve the screening effect, the second motor 41 on the mounting plate 12 starts to rotate, driving the gear 42 connected to it to rotate synchronously; while the gear 42 rotates, the gear ring 43 meshing with it also rotates. Since the gear ring 43 is fixed on the mounting cylinder 44, which is set on the support plate 11, it drives the mounting cylinder 44 to rotate; at this time, the screen 335 is in a closed state, and the rotation of the mounting cylinder 44 drives the screen 335 to rotate synchronously, realizing efficient screening of the material inside the screen 335; under the action of centrifugal force, the material moves in a high-speed circular motion along the inner wall of the screen 335, and the fine particles quickly pass through the mesh and fall into the collection chamber below by means of centrifugal force and contact friction with the screen 335, while the larger particles are continuously retained in the screen 335 because they cannot pass through the mesh, until the coarse and fine classification is completed.

[0020] The working principle of the above embodiments is as follows: 1. To achieve control of the telescopic assembly, a first motor 21 is mounted on a mounting plate 12, which is mounted on a mounting base 1. When the first motor 21 rotates, it drives the connected drive wheel 22 to rotate. The drive wheel 22 drives the transmission wheel 24 to rotate via a belt 23. A connecting shaft 25 is provided on the transmission wheel 24, which is connected to the telescopic assembly 3, thereby driving the turntable 31 on the telescopic assembly 3 to rotate. The rotation of the turntable 31 controls the opening and closing of the telescopic assembly 3. To achieve disassembly, the limiting block 331 adopts a cylindrical structure design, and its outer diameter forms a clearance fit with the arc groove diameter of the U-shaped groove 32. When the turntable 31 on the telescopic assembly 3 rotates, the limiting block 331 rotates synchronously along the U-shaped groove 32, thereby driving the movable block 332, which is fixedly connected to it, to slide on the fixed block 333. A frame 334 is connected to one side of the movable block 332, pushing the frame 334 to open outward, and the screen 335 opens outward along with the frame 334. Because the screen 335 is designed to be detachable, when a part of the screen 335 is damaged, the screen 335 can be opened through the telescopic component 3 and the damaged part of the screen 335 can be directly removed for repair.

[0021] 2. To achieve the screening effect, the second motor 41 on the mounting plate 12 starts to rotate, driving the gear 42 connected to it to rotate synchronously; as the gear 42 rotates, the gear ring 43 meshing with it also rotates. Since the gear ring 43 is fixed on the mounting cylinder 44, which is set on the support plate 11, the mounting cylinder 44 is driven to rotate; at this time, the screen 335 is in a closed state, and the rotation of the mounting cylinder 44 drives the screen 335 to rotate synchronously, realizing the efficient screening of the material inside the screen 335; under the action of centrifugal force, the material moves in a high-speed circular motion along the inner wall of the screen 335, and the fine particles quickly pass through the mesh and fall into the collection chamber below by means of centrifugal force and contact friction with the screen 335, while the larger particles are continuously retained in the screen 335 because they cannot pass through the mesh, until the coarse and fine classification is completed.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
