Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen that facilitates screen replacement. Background Technology

[0002] A vibrating screen is a device that uses mechanical vibration to classify and screen materials. Its core principle is to drive the screen body with a vibrator to generate high-frequency directional vibration, causing the material to continuously toss and move on the screen surface, thereby achieving efficient separation according to particle size. This equipment typically consists of a screen box, vibration damping device, transmission system, and screen mesh, and can be configured with single or multiple screen layers depending on requirements. Vibrating screens are characterized by large processing capacity, high screening accuracy, and strong adaptability, and are widely used in mining, building materials production, chemical raw material preparation, and grain processing.

[0003] Vibrating screens mainly rely on excitation devices to make the screen frame move periodically, thereby quickly classifying particulate materials according to particle size. In actual operation, the screen is a consumable part and requires frequent shutdowns for replacement. The existing bolt-plate method of disassembly and assembly is time-consuming and requires multiple people to cooperate, which is even more difficult when the maintenance passage is narrow. At the same time, the external vibration motor or eccentric block structure increases the number of parts in the whole machine and the energy consumption is high, making it difficult to meet the needs of high efficiency, energy saving and rapid maintenance. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a vibrating screen that facilitates screen replacement, solving the technical problem in related technologies / existing technologies where the screen is fixed and installed with bolts, making it inconvenient to disassemble, replace, and position it.

[0005] The device includes a support frame, on the surface of which a motor is fixedly mounted. A rotating shaft is fixedly connected to the output end of the motor. An open pipe is fixedly connected to the output end of the rotating shaft. A connecting platform is rotatably connected to the surface of the open pipe. A fixed side lug is rotatably connected inside the connecting platform. A vibrating frame is fixedly connected to the top of the fixed side lug. A fixed plate is fixedly connected to the surface of the vibrating frame. A first fixed column is fixedly connected to the surface of the fixed plate. A connecting rod is hinged to the surface of the first fixed column. A second fixed column is hinged inside the connecting rod. A vibrating screen is snapped into the inside of the vibrating frame. A limit assembly is fixedly connected to the surface of the fixed plate.

[0006] Through the above technical solution, by setting up a motor, rotating shaft, open pipe, connecting platform, fixed side lug, vibrating frame, connecting rod, fixed column one, fixed column two, and an inclined vibrating screen, when the motor rotates, the open pipe pulls the connecting platform left and right due to eccentricity, and the connecting rod converts the left and right movement into the up-down and left-right periodic motion of the vibrating frame, so that the vibrating screen can continuously vibrate and screen the passing material in multiple dimensions, achieving the effect of high-efficiency and low-energy-consumption screening without the need for additional excitation elements.

[0007] As a further improvement to the above scheme, the number of connecting rods is set to four, and the four connecting rods are symmetrically distributed around the top center of the vibration frame.

[0008] With the above technical solution, the four connecting rods are symmetrically arranged around the top center of the vibration frame, so that the vibration frame is subjected to uniform force, runs smoothly, avoids uneven wear, and extends the service life of the whole machine.

[0009] As a further improvement to the above solution, the end of the second fixed column away from the connecting rod is fixedly connected to the surface of the support frame.

[0010] Through the above technical solution, the second fixed column is fixed on the support frame, providing a reliable fulcrum for the connecting rod and ensuring that the composite motion trajectory of the vibration frame is stable and repeatable.

[0011] As a further improvement to the above solution, a slide rail is fixedly connected to the inner wall of the vibration frame, and a slide bar is slidably connected inside the slide rail.

[0012] Through the above technical solution, the slide rail and slide bar cooperate to form a sliding pair between the vibrating screen and the vibrating frame, resulting in low resistance and accurate positioning when the screen is disassembled and assembled.

[0013] As a further improvement to the above solution, the number of slide rails is set to four, and the four slide rails are symmetrically distributed around the top center of the vibrating frame. The end of the slide bar away from the slide rail is fixedly connected to the surface of the vibrating screen.

[0014] With the above technical solution, the four slide rails are symmetrically distributed in the center, and the screen is supported synchronously around the perimeter, preventing material leakage or reduction in screening efficiency due to local deformation.

[0015] As a further improvement to the above solution, the limiting component includes a limiting sleeve fixedly connected to the front of the fixed plate, an extrusion plate slidably connected inside the limiting sleeve, a locking post fixedly connected to the front end of the extrusion plate, a connecting post fixedly connected to the rear end of the extrusion plate, a spring sleeved on the surface of the connecting post, a pull plate fixedly connected to the end of the connecting post away from the extrusion plate, a limiting hole opened at the top of the connecting post, and a locking hole opened on the surface of the vibrating screen.

[0016] Through the above technical solution, the limiting sleeve, the squeezing plate, the locking post, the connecting post, the spring, the pull plate, the limiting hole and the locking hole together constitute a self-locking quick-release mechanism. Pulling the pull plate outward can unlock the mechanism, and the spring will automatically reset and lock after being released.

[0017] As a further improvement to the above solution, the front end of the locking post penetrates the inner wall of the vibration frame and is locked inside the locking hole.

[0018] Through the above technical solution, the card is equipped with a limiting component consisting of a limiting sleeve, a squeezing plate, a locking post, a connecting post, a spring, a pull plate, a limiting hole, and a locking hole. When replacing the screen, simply pull the pull plate to make the locking post instantly exit the locking hole. After inserting the pin to lock it, the vibrating screen can be slid out along the slide rail, which can quickly complete the screen disassembly and assembly and shorten the maintenance time.

[0019] As a further improvement to the above solution, the front and rear ends of the spring are in contact with the surface of the extrusion plate and the inner wall of the limiting sleeve, respectively.

[0020] With the above technical solution, the two ends of the spring abut against the extrusion plate and the limiting sleeve respectively, and the spring preload keeps the pin inserted into the card hole, preventing the limiting from failing due to vibration.

[0021] The beneficial effects of this utility model are as follows: This utility model includes a motor, a rotating shaft, an open pipe, a connecting platform, fixed side ears, a vibrating frame, a connecting rod, a first fixed column, a second fixed column, and an inclined vibrating screen. When the motor rotates, the open pipe pulls the connecting platform left and right due to eccentricity. The connecting rod converts the left and right movement into the up-down and left-right periodic motion of the vibrating frame, so that the vibrating screen can continuously and multidimensionally vibrate and screen the passing materials.

[0022] This utility model uses a limiting assembly consisting of a limiting sleeve, a pressing plate, a locking post, a connecting post, a spring, a pull plate, a limiting hole, and a locking hole. When replacing the screen, simply pull the pull plate to make the locking post instantly disengage from the locking hole. After inserting the pin to lock it, the vibrating screen can slide out along the slide rail, thus quickly completing the screen disassembly and assembly and shortening maintenance time.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-3 As shown, this invention illustrates a vibrating screen with easy screen replacement according to one embodiment of the present invention. It includes a support frame 1, a motor 2 fixedly mounted on the surface of the support frame 1, a rotating shaft 3 fixedly connected to the output end of the motor 2, an open pipe 4 fixedly connected to the output end of the rotating shaft 3, the open pipe 4 and the rotating shaft 3 not being at the same center, so that the open pipe 4 rotates around the center of the rotating shaft 3 when rotating, a connecting platform 5 rotatably connected to the surface of the open pipe 4, a fixed side lug 6 rotatably connected inside the connecting platform 5, a vibrating frame 7 fixedly connected to the top of the fixed side lug 6, and vibration generated by the vibrating frame 7, a fixed plate 8 fixedly connected to the surface of the vibrating frame 7, a fixed column 9 fixedly connected to the surface of the fixed plate 8, a connecting rod 10 hinged to the surface of the fixed column 9, a second fixed column 11 hinged inside the connecting rod 10, a vibrating screen 14 snapped into the inside of the vibrating frame 7, and material screening performed by the vibrating screen 14. Large particles are discharged through the output end of the screen, while suitable particles fall to the bottom for collection. A limit assembly is fixedly connected to the surface of the fixed plate 8.

[0032] This embodiment provides a vibrating screen that facilitates screen replacement. When the motor 2 is started, its output drives the rotating shaft 3 to rotate. The rotating shaft 3 then drives the open pipe 4 to rotate. Since the center of the open pipe 4 is different from that of the support frame 1, the rotation of the open pipe 4 pulls the connecting platform 5 to move left and right. Simultaneously, when the connecting platform 5 wobbles left and right, it causes the fixed side lug 6 and the vibrating frame 7 to wobble left and right. At the same time, the wobbling of the vibrating frame 7 causes the vibrating screen 14 to wobble inside the vibrating frame 7. Because the entire vibrating frame 7 is angled to the ground, the wobbling of the vibrating frame 7, driven by the connecting rod 10, produces a periodic up-down-left-right motion, thus performing vibrating screening of the material passing through the vibrating screen 14.

[0033] Furthermore, the number of connecting rods 10 is set to four, and the four connecting rods 10 are symmetrically distributed around the top center of the vibration frame 7. The four connecting rods 10 are arranged symmetrically around the top center of the vibration frame 7, so that the vibration frame 7 is subjected to uniform force and runs smoothly, avoiding uneven wear, which could lead to vibration failure or the vibration amplitude being uncontrollable and causing deviation.

[0034] Furthermore, the end of the second fixed column 11 away from the connecting rod 10 is fixedly connected to the surface of the support frame 1. The second fixed column 11 is fixed on the support frame 1, providing a reliable fulcrum for the connecting rod 10, and ensuring that the composite motion trajectory of the vibration frame 7 is stable and repeatable.

[0035] refer to Figure 3 The inner wall of the vibrating frame 7 is fixedly connected to a slide rail 12, and a slide bar 13 is slidably connected inside the slide rail 12. The slide rail 12 and the slide bar 13 cooperate to form a sliding pair between the vibrating screen 14 and the vibrating frame 7, resulting in low resistance and accurate positioning when the screen is disassembled and assembled.

[0036] Furthermore, four slide rails 12 are provided, which are symmetrically distributed around the top center of the vibrating frame 7. The end of the slide bar 13 away from the slide rail 12 is fixedly connected to the surface of the vibrating screen 14. The four slide rails 12 are symmetrically distributed around the center, and the screen is synchronously supported around the perimeter to prevent material leakage or reduction in screening efficiency due to local deformation.

[0037] refer to Figure 3 and Figure 4 In some embodiments, the limiting component includes a limiting sleeve 15 fixedly connected to the front of the fixed plate 8. A pressing plate 16 is slidably connected inside the limiting sleeve 15. A locking post 17 is fixedly connected to the front end of the pressing plate 16, and a connecting post 18 is fixedly connected to the rear end of the pressing plate 16. A spring 19 is sleeved on the surface of the connecting post 18. The force generated by the spring 19 pressing the pressing plate 16 is stored. When locking is required, the spring 19 limits the locking post 17 to prevent it from detaching from the inside of the vibrating screen. A pull plate 20 is fixedly connected to the end of the connecting post 18 away from the pressing plate 16. A limiting hole 21 is opened at the top of the connecting post 18, and a locking hole 22 is opened on the surface of the vibrating screen 14.

[0038] In this embodiment, when it is necessary to replace the vibrating screen, the connecting column 18 is pulled by the pull plate 20 to slide inside the limiting sleeve 15. At this time, the pressing plate 16 presses the spring 19, and the locking column 17 disengages from the inside of the locking hole 22. At the same time, the limiting hole 21 disengages from the inside of the limiting sleeve 15. The pin is inserted into the inside of the limiting hole 21, and the vibrating screen 14 can be pulled out from the inside of the vibrating frame 7 for replacement.

[0039] Furthermore, the front end of the locking post 17 penetrates the inner wall of the vibrating frame 7 and is locked inside the locking hole 22. The locking post 17 penetrates the inner wall of the vibrating frame 7 and is directly locked into the screen locking hole 22, thereby achieving a rigid connection between the screen and the frame and preventing the screen from sliding out on its own during high-frequency vibration.

[0040] Furthermore, the front and rear ends of the spring 19 are in contact with the surface of the extrusion plate 16 and the inner wall of the limiting sleeve 15, respectively. The two ends of the spring 19 abut against the extrusion plate 16 and the limiting sleeve 15, respectively. The pre-tightening force of the spring 19 keeps the locking post 17 continuously inserted into the locking hole 22. When the extrusion plate 16 extrudes the spring 19, the locking post 17 disengages from the inside of the locking hole 22. When the extrusion force generated on the extrusion plate 16 is released, the locking post 17 penetrates the vibration frame 7 under the rebound force of the spring 19 and is locked inside the locking hole 22 to limit and fix the vibrating screen.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
