Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen with uniform material distribution function. Background Technology

[0002] A vibrating screen is a high-frequency material screening device. It works by applying an excitation force to the screen mesh, causing it to vibrate at high frequency, thus screening and filtering materials. Vibrating screens are widely used in various industries. Vibration can effectively complete many processes or improve the working efficiency of certain machinery, leading to the comprehensive and rapid development of screening machinery.

[0003] The prior art can be referred to Chinese Patent No. CN118122612A, which discloses a vibrating screen with a material distribution function, including a frame, a vibrating mechanism set on the frame, and a feed hopper set on the frame and located above the vibrating mechanism. It also includes a movable frame set on the feed hopper and a material distribution mechanism set at the bottom of the movable frame. However, this vibrating screen is not convenient for guiding the material in the feed hopper during use, which can easily lead to material blockage in the feed hopper and cause feeding failure. Therefore, a vibrating screen with a uniform material distribution function is provided now. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vibrating screen with uniform material distribution function. Through the coordinated use of a hinged support frame, a vibrating component, a tamping frame, and a material-pushing component, the material in the feed hopper is repeatedly agitated, thereby preventing the material from getting stuck in the feed hopper, achieving stable feeding, and assisting the material to be evenly spread on the screening screen plate for screening. This largely avoids the problem of material being concentrated and piled up in the middle of the filter screen, resulting in excessive accumulation and insufficient screening and filtration, thus overcoming the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibrating screen with uniform material distribution function includes a support frame. Two fixed rods are symmetrically fixed on one side of the upper end face of the support frame. A screening screen plate is rotatably installed between the two fixed rods. A hinged support frame is installed between the end of the screening screen plate away from the fixed rods and one end of the support frame. The screening screen plate is in an inclined state. A vibration component that cooperates with the hinged support frame is fixed to one end of the support frame. Two vertical rods are symmetrically fixed on the other side of the upper end face of the support frame. A feed hopper is installed between the tops of the two vertical rods. A tamping frame that cooperates with the hinged support frame is installed on one side of the top of the feed hopper. Baffles are fixed at both ends of the upper end face of the screening screen plate. A material feeding component is installed between the two baffles.

[0007] The material tamping frame includes a first connecting rod rotatably mounted on one side of the top of the feed hopper.

[0009] As a further embodiment of this utility model: the vibration assembly includes a support plate fixed to one end of the support frame, a first servo motor fixed to one side of the vertical section of the support plate, an eccentric block connected to the output end of the first servo motor, and an abutment block fixed to one side of the second support rod, with the eccentric block abutting against the abutment block.

[0010] As a further improvement of this utility model, the lower end of the second connecting rod is rotatably connected to the middle part of the first support rod.

[0011] As a further improvement of this utility model, two tension springs are symmetrically fixed between the lower end face of the support plate and the upper end face of the support frame.

[0012] As a further embodiment of this utility model: the material feeding assembly includes rotating rods rotatably mounted between the two ends of two baffles via bearings, with two sprockets symmetrically arranged on each of the two rotating rods, and chains connecting the two sprockets at both ends of the two rotating rods, and two material feeding plates evenly fixed between the two chains.

[0013] As a further embodiment of this utility model: a speed reducer is installed on one side of one of the baffles, the output end of the speed reducer is connected to one end of one of the rotating rods, the input end of the speed reducer is connected to a second servo motor, and the second servo motor is fixed to the outer wall of the speed reducer.

[0014] As a further improvement of this utility model, support legs are fixed at the four corners of the lower end face of the support frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] By using the hinged support frame, vibration component, tamping frame and material feeding component in combination, the material in the feed hopper is repeatedly agitated, thereby avoiding material getting stuck in the feed hopper, achieving stable feeding, and assisting the material to be evenly spread on the screening screen plate for screening. This largely avoids the problem of material being concentrated and piled up in the middle of the filter screen, resulting in excessive accumulation and insufficient screening and filtration.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-5 A vibrating screen with uniform material distribution function includes a support frame 1. Two fixed rods 4 are symmetrically fixed on one side of the upper end face of the support frame 1. A screening screen 13 is rotatably installed between the two fixed rods 4. A hinged support frame is installed between the end of the screening screen 13 away from the fixed rods 4 and the end of the support frame 1. The screening screen 13 is in an inclined state. A vibration component that works with the hinged support frame is fixed at one end of the support frame 1. Two vertical rods 2 are symmetrically fixed on the other side of the upper end face of the support frame 1. A feed hopper 10 is installed between the tops of the two vertical rods 2. A tamping frame that works with the hinged support frame is installed on one side of the top of the feed hopper 10. Baffles 3 are fixed at both ends of the upper end face of the screening screen 13. A material feeding component is installed between the two baffles 3. Support legs are fixed at the four corners of the lower end face of the support frame 1.

[0025] The material tamping frame includes a first connecting rod 9 rotatably mounted on one side of the top of the feed hopper 10. The end of the first connecting rod 9 located above the feed hopper 10 is rotatably connected to a material tamping rod 8. The lower end of the material tamping rod 8 extends to the lower interior of the feed hopper 10 and is connected to a toggle rod 21. The end of the first connecting rod 9 located outside the feed hopper 10 is rotatably connected to a second connecting rod 11.

[0026] The hinged support frame includes a support plate 14 fixed to one end of the screening screen plate 13. A first support rod 16 is rotatably mounted in the middle of the support plate 14. A second support rod 17 is rotatably connected to one end of the first support rod 16. One end of the second support rod 17 is rotatably connected to one end of the support frame 1.

[0027] The vibration assembly includes a support plate 18 fixed to one end of the support frame 1. A first servo motor 22 is fixed to one side of the vertical section of the support plate 18. An eccentric block 23 is connected to the output end of the first servo motor 22. An abutment block 24 is fixed to one side of the second support rod 17. The eccentric block 23 abuts against the abutment block 24.

[0028] The lower end of the second link 11 is rotatably connected to the middle of the first support rod 16.

[0029] Two tension springs 15 are symmetrically fixed between the lower end face of the support plate 14 and the upper end face of the support frame 1.

[0030] Material falls onto the screening screen plate 13 through the feed hopper 10. The first servo motor 22 drives the eccentric block 23 to rotate, causing the eccentric block 23 to strike the abutment block 24. The abutment block 24 drives the second support rod 17 and the first support rod 16 to swing, thereby using the first support rod 16 to drive the screening screen plate 13 to vibrate and screen the material. While the first support rod 16 swings, it drives the second connecting rod 11, the first connecting rod 9 and the tamping rod 8 to vibrate up and down. The tamping rod 8 drives the agitator 21 to repeatedly move the material at the bottom of the feed hopper 10, thereby preventing the material from getting stuck in the feed hopper 10 and achieving stable feeding.

[0031] Example 2 is an optimization based on Example 1, specifically:

[0032] The material feeding assembly includes a rotating rod 5 that is rotatably mounted between the two ends of two baffles 3 via bearings. Two sprockets 6 are symmetrically arranged on each of the two rotating rods 5. A chain 7 is connected between the two sprockets 6 at both ends of the two rotating rods 5. Two material feeding plates 19 are evenly fixed between the two chains 7.

[0033] A speed reducer 12 is installed on one side of one of the baffles 3. The output end of the speed reducer 12 is connected to one end of one of the rotating rods 5. The input end of the speed reducer 12 is connected to a second servo motor 20, and the second servo motor 20 is fixed to the outer wall of the speed reducer 12.

[0034] During the screening process on the screening screen plate 13, the second servo motor 20 drives the reducer 12 to rotate, which in turn drives the rotating rod 5, sprocket 6 and chain 7 to rotate. The rotation of the two chains 7 drives the two material-pushing plates 19 to move, so that the two material-pushing plates 19 repeatedly push the material on the screening screen plate 13, helping the material to be evenly spread on the screening screen plate 13 for screening. This largely avoids the problem of material being concentrated and piled up in the middle of the filter screen, resulting in excessive accumulation and insufficient screening and filtration.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
