Description

Technical Field

[0001] The utility model relates to the technical field of vibrating feeders, in particular to an electromagnetic vibrating feeder for producing fly ash in concrete production. Background Art

[0002] The scientific use of fly ash has become a crucial component in concrete production. Fly ash offers multiple advantages, including improved concrete workability, enhanced durability, and reduced production costs. Electromagnetic vibrating feeders are often used for fly ash transportation. These feeders are used to uniformly and quantitatively deliver material from silos or other storage equipment to receiving equipment, making them essential for automated assembly lines. They are used for quantitative or continuous delivery of bulk, granular, or powdered materials. They are widely used in industries such as mining, metallurgy, coal, power generation, chemicals, food, glass, and refractory materials.

[0003] In the prior art, the force and amplitude of an electromagnetic vibrating feeder are usually adjusted by adjusting the motor output torque and the position of the eccentric block. However, when adjusting the vibration amplitude, the eccentric block often needs to be removed for adjustment, which increases the workload. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides an electromagnetic vibrating feeder for fly ash in concrete production, which has the advantages of easy adjustment of amplitude, greater eccentricity and stronger vibration amplitude, and solves the problems raised by the above background technology.

[0005] The utility model provides the following technical solution: an electromagnetic vibrating feeder for fly ash in concrete production, comprising a frame, four corners of the frame are provided with support legs, the support legs include two groups, a front support leg group and a rear support leg group, the height of the rear support leg group is higher than that of the front support leg group, a feed box is provided on the top of the frame, a connecting spring is fixedly connected between the support legs and the feed box, a hopper is provided on the top of one end of the feed box, the hopper is communicated with the interior of the feed box, a sliding block is provided on the inner bottom wall of the feed box, a triangular box is provided on the bottom of the feed box between the support legs, a stop block is fixedly connected to one side of the frame, a spring control plate is provided between one side of the stop block and one side of the triangular box, and one side of the spring control plate is fixedly connected to the vibration box.

[0006] Through the above-mentioned structural setting, when using this device to vibrate and feed coal ash, the amplitude of the vibration feeding can be adjusted by adjusting the size of the motor output torque. When the rotating block rotates at an insufficient speed, the movable block located at the outermost circle of the rotating block will not be driven to rotate. When the rotating block rotates at a maximum speed, the movable block will rotate with the rotating block, and the amplitude will reach the inner wall of the vibration box to achieve maximum amplitude vibration.

[0007] Preferably, a vibration spring A is fixedly connected between the spring control plate and one side of the triangular box, a vibration spring B is fixedly connected between the spring control plate and one side of the stop block, and fixed legs are fixedly installed on both sides of one side of the vibration box.

[0008] Through the above-mentioned structural setting, after the vibration spring A and the vibration spring B are set, a buffer space is provided for the vibration of the vibration box. At the same time, when the moving block inside the vibration box rotates, it can timely drive the feed box to vibrate, so that the coal ash inside the feed box can be vibrated and transported in time.

[0009] Preferably, rotating blocks are rotatably installed on both sides of the vibration box, one side of the rotating block is located inside the vibration box, and a motor is fixedly installed with the axis center of one side of the rotating block located at the end of the fixed leg. The rotating block is fixedly connected to the output shaft of the motor, and a movable block is movably installed between the rotating blocks inside the vibration box.

[0010] Through the above-mentioned structural setting, when the motor drives the rotating block to rotate, it can drive the movable block located between the rotating blocks to perform a large-scale eccentric rotation. When the rotating block drives the movable block located between it to rotate, it can also drive the movable block located on the outer ring of the slide bar to slide, thereby achieving the effect of maximum-scale eccentric rotation.

[0011] Preferably, a slide groove A is provided on one side of the movable block, and a slide groove B is provided on the other side of the movable block, and the slide groove A and the slide groove B are at a vertical angle.

The sliding bar of the rotating block on one side is adapted to the slide groove A, and the sliding bar of the rotating block on the other side is adapted to the slide groove B, and the movable block is slidably arranged on the outer ring of the sliding bar.

[0012] Through the above-mentioned structural setting, when the movable block rotates and slides and comes into contact with the inner wall of the vibration box, the eccentrically rotating movable block can drive the vibration box to vibrate. While the vibration box vibrates, it drives the vibration spring A and the vibration spring B to perform reciprocating operations such as contraction and release, thereby driving the feed box to vibrate and feed.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The electromagnetic vibrating feeder for fly ash in concrete production realizes feeding with strong vibration amplitude by setting structures such as a vibration box, a rotating block, and a moving block. When the motor is started, the motor will drive the rotating block to rotate continuously. Since the position of the moving block is restricted by the slide bar, the moving block rotates with the rotating block. When it rotates to a certain angle, the moving block will be located on the outer ring of the slide bar on one side and slide outward, but the moving block will also slide toward the middle of the slide bar on the other side. When the moving block rotates and slides, it will overlap with the positions of the rotating blocks on both sides. The rotating blocks on both sides clamp the moving block for a large eccentric rotation, so that the vibration obtained by the spring control plate is stronger, and the feed box can feed the fly ash more powerfully and quickly, achieving a conveying effect with a strong vibration amplitude.

[0015] 2. The electromagnetic vibrating feeder for fly ash in concrete production can adjust the vibration amplitude by setting different structures such as motor, moving block and slide bar. By adjusting the output torque of the motor, the speed of the rotating block is driven to rotate at different speeds, and the rotation sliding amplitude of the moving block between the rotating blocks is adjusted. When the motor drives the rotating block to rotate slowly, the sliding speed of the moving block on the outer ring of the slide bar is slowed down, and its vibration amplitude and vibration frequency are slowed down. When the motor drives the rotating block to rotate quickly, the vibration amplitude and vibration frequency of the moving block are increased, which has the effect of adjusting the vibration amplitude without disassembly.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When using this device to vibrate and feed fly ash, the amplitude of the vibration feeding can be adjusted by adjusting the size of the torque output by the motor 52. When the rotating block 51 rotates at an insufficient speed, the movable block 53 located at the outermost circle of the rotating block 51 will not be driven to rotate. When the rotating block 51 rotates at a maximum speed, the movable block 53 rotates with the rotating block 51, and the amplitude will reach the inner wall of the vibration box 5, thereby achieving maximum amplitude vibration.

[0024] See also Figures 1-4 A vibration spring A41 is fixedly connected between the spring control plate 4 and one side of the triangular box 23, a vibration spring B42 is fixedly connected between the spring control plate 4 and one side of the block 3, and a fixed leg 43 is fixedly installed on both sides of the vibration box 5 on one side of the spring control plate 4.

[0025] After the vibration spring A41 and the vibration spring B42 are set, a buffer space is provided for the vibration of the vibration box 5. At the same time, when the moving block 53 inside the vibration box 5 rotates, it can timely drive the feed box 2 to vibrate, so that the coal ash inside the feed box 2 is timely vibrated and transported. The vibration spring A41 and the vibration spring B42 respectively play the role of connecting the feed box 2 and the block 3.

[0026] See also Figures 1-4, rotating blocks 51 are rotatably installed on both sides of the vibration box 5, one side of the rotating block 51 is located inside the vibration box 5, and the center of the axis of one side of the rotating block 51 is located at the end of the fixed leg 43 where a motor 52 is fixedly installed. The rotating block 51 is fixedly connected to the output shaft of the motor 52. The rotating blocks 51 are arranged on both sides of the movable block 53, and the positions do not correspond. When viewed from one side of the rotating block 51, there is an overlapping area between the rotating blocks 51. When the motor 52 drives the output shaft to rotate, it can drive the rotating block 51 to rotate synchronously. The interior of the vibration box 5 is movably installed with a movable block 53 between the rotating blocks 51.

[0027] When the motor 52 drives the rotating block 51 to rotate, it can drive the movable block 53 located between the rotating blocks 51 to perform a large-scale eccentric rotation. When the rotating block 51 drives the movable block 53 located between it to rotate, it can also drive the movable block 53 located on the outer circle of the slide bar 54 to slide, achieving the effect of maximum eccentric rotation.

[0028] See also Figures 1-4 A slide groove A531 is provided on one side of the movable block 53, and a slide groove B532 is provided on the other side of the movable block 53. The slide groove A531 and the slide groove B532 are at a vertical angle. A slide bar 54 is provided on the side of the rotating block 51 close to the movable block 53. The slide bar 54 is adapted to the slide groove A531 and the slide groove B532. The slide bar 54 of the rotating block 51 on one side is adapted to the slide groove A531, and the slide bar 54 of the rotating block 51 on the other side is adapted to the slide groove B532. The movable block 53 is slidably arranged on the outer ring of the slide bar 54.

[0029] Due to the setting of the vibration box 5, when the movable block 53 is located between the rotating blocks 51 and rotates and slides, it can be restricted by the inside of the vibration box 5. When the movable block 53 rotates and slides and wants to contact the inner wall of the vibration box 5, the eccentrically rotating movable block 53 can drive the vibration box 5 to vibrate. While the vibration box 5 vibrates, it drives the vibration spring A41 and the vibration spring B42 to perform reciprocating operations such as contraction and release, thereby driving the feed box 2 to vibrate and feed.

[0030] Working principle: The coal ash is continuously injected into the interior of the feed box 2 through the hopper 21. When the coal ash contacts the sliding block 22, due to the angle of the sliding block 22, it will first slide toward the two walls of the feed box 2 or the opening of the feed box 2. At this time, the motor 52 is started, and the motor 52 will drive the rotating block 51 to rotate continuously. Since the position of the movable block 53 is limited by the slide bar 54, the movable block 53 rotates together with the rotating block 51. When it rotates to a certain angle, the movable block 53 will be located on the outer circle of the slide bar 54 on one side and slide outward, but the movable block 53 will also slide toward the middle of the slide bar 54 on the other side. When the movable block 53 rotates and slides, it will overlap with the positions of the rotating blocks 51 on both sides. The rotating blocks 51 on both sides clamp the movable block 53 for a large-scale eccentric rotation, so that the vibration of the spring control plate 4 is stronger, so that the feed box 2 can feed the coal ash more powerfully and quickly.
