Description

Technical Field

[0001] This invention relates to the field of concrete mixing equipment technology, specifically a high-performance concrete mixing equipment for small box girder bridges. Background Technology

[0002] With the increasing number of transportation vehicles, highways and railways have begun to expand from the ground to the air, resulting in the ever-growing number of road and bridge engineering projects. Small box girders, a type of beam in bridge engineering, are hollow inside with flanges on both sides of the upper part, resembling a box, hence the name. Small box girders are advantageous due to their good overall structural integrity and ease of erection. As a prefabricated structure, small box girders are easily mechanized and factory-constructed. Because they only have end diaphragms, the visual appearance under the bridge is simple, and their relatively low beam height offers advantages in areas where beam height is limited and aesthetic requirements are high. The structure has strong adaptability to widening and a wide range of applications. However, the fabrication of small box girder bridges requires a large amount of concrete raw materials, necessitating the mixing and processing of these materials using concrete mixing equipment to meet usage requirements.

[0003] Currently, when mixing concrete raw materials, the materials tend to accumulate, leading to uneven mixing. The excessive resistance caused by the accumulated materials can also damage the equipment. In addition, when mixing wet sand, the sand tends to stick together, forming clumps, which further affects the mixing of the raw materials and consequently the overall performance of the concrete. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-performance concrete mixing equipment for small box girder bridges, comprising:

[0005] A mixing tank is provided with a discharge port at the bottom for easy discharge. A servo motor is fixedly connected to the center of the top of the mixing tank for power. Support legs are fixedly connected to the bottom of the mixing tank near the edge.

[0006] Also includes:

[0007] The mixing mechanism includes a drive cylinder rotatably connected to the top center of the inner surface of the mixing tank, and a support column fixed to the bottom center of the inner surface of the mixing tank. The inner surface of the drive cylinder is rotatably connected to the outer surface of the support column, and a pressing rod is fixedly connected to the outer surface of the support column near the inner surface of the drive cylinder. A mixing component is provided on the outer surface of the drive cylinder, and a dispensing module is provided on the top of the drive cylinder. A servo motor is used as the power source, and the drive cylinder is supported by the support column, which extends into the interior of the drive cylinder and can rotate on the outer surface of the support column. This allows the drive cylinder to be smoothly driven to rotate, preventing it from shaking. Consequently, the mixing component and the dispensing module are driven to rotate in a circular motion, mixing the concrete raw materials in the mixing tank. The smooth driving not only reduces the resistance during mixing but also promotes thorough mixing of the raw materials.

[0008] The feeding assembly includes a hopper fixed to the top of the mixing tank near the servo motor. An elastic strip is fixedly connected to the inner surface of the hopper near the bottom. A triangular piece is fixedly connected to the top of the outer surface of the elastic strip, and a connecting rod is fixedly connected to the bottom of the elastic strip. A roller is installed at the bottom of the connecting rod, and a crescent-shaped piece is fixedly connected to the top of the outer surface of the connecting rod. Concrete raw materials are fed from the hopper. After entering the hopper, the concrete raw materials are broken up by their own weight and the crescent-shaped piece, thus performing pretreatment. Simultaneously, as the top cap drives the dispensing blades to rotate, it not only dispenses the falling raw materials but also provides an upward pushing force to the rollers through contact with the rotating blades. Under the elastic support of the elastic strip, the connecting rod drives the crescent-shaped piece to move into the hopper, compressing the elastic strip. The triangular piece and crescent-shaped piece together circulate the concrete raw materials in the hopper, preventing blockages and effectively connecting the structures together.

[0009] Preferably, the top end of the drive cylinder penetrates the top of the inner surface of the mixing tank and extends to the outside. The top end of the drive cylinder is fixedly connected to the output end of the servo motor through a coupling. A rotating hole adapted to the support column is opened at the center of the bottom of the drive cylinder.

[0010] Preferably, the mixing assembly includes mixing blades, the outer surface end of which is slidably connected to the outer surface of the drive cylinder. A hook piercing element is fixedly connected to the top of the outer surface of the mixing blades. A semi-circular pressure block is fixedly connected to the outer surface end of the mixing blades near the pressing rod. A reset spring is fixedly connected to the top of the outer surface of the mixing blades near the semi-circular pressure block. The top of the reset spring is fixedly connected to the inner surface of the drive cylinder. A strong magnet is fixedly connected to the bottom of the outer surface of the mixing blades near the bottom of the drive cylinder. When the drive cylinder rotates, it drives the entire mixing assembly to rotate in a circular motion. At this time, the rotating mixing blades agitate the concrete raw materials in the mixing tank, and the support column supports the pressing rod, causing the pressing rod to... The pressure bar is stationary, and as the mixing blades rotate, the semi-circular pressure block also rotates. The outer edge of the semi-circular pressure block is in contact with the outer surface of the pressure bar. At this time, the rotating semi-circular pressure block is subjected to the outward pressing force of the pressure bar, causing the mixing blades to move outward of the drive cylinder. The hook piercing part moves with the mixing blades, and the reset spring is compressed. When the semi-circular pressure block separates from the pressure bar, the pressing force disappears, and under the elastic force of the reset spring, the mixing blades drive the hook piercing part to reset. This reciprocating movement allows the mixing blades and the hook piercing part to not only rotate in a circle but also move downward in a straight line, increasing the angular direction of the concrete raw materials and enabling timely breaking up of clumps of sand.

[0011] Preferably, the stirring blades are evenly distributed on the outer surface of the drive cylinder, and the outer surface of the drive cylinder is provided with sliding holes that are adapted to the outer surface ends of the stirring blades. The outer surface edge of the semi-circular pressure block is in contact with the outer surface of the pressing rod.

[0012] Preferably, the dispensing module includes a support frame, with a top cap fixedly connected to the top of the support frame. The top of the top cap is fixedly connected to the top of the outer surface of the drive cylinder. A drain is provided on the edge of the outer surface of the top cap, and a dispensing blade is fixedly connected to the top of the outer surface of the top cap near the drain. When the drive cylinder is driven, the entire dispensing module is also driven to rotate. At this time, the support frame supports the top cap, which is conical. The falling concrete material slides down the inclined surface of the top cap at a uniform speed, and the drain leaks some of the concrete material. As the dispensing blade rotates, the concrete material can be dispensed, thus allowing the concrete material to fall evenly into the mixing tank. At the same time, the dispensing blade will contact the roller on the discharging component, so that the dispensing blade and the roller interact with each other. Through the interaction between the structures, the structures are connected together.

[0013] Preferably, the leaks are evenly distributed on the outer edge of the top cap, the spray blades are evenly distributed on the top of the outer surface of the top cap, and the leaks and spray blades are arranged alternately.

[0014] Preferably, the hopper is cone-shaped, the outer surface of the elastic strip is curved, and the tip of the triangular piece is tilted upward.

[0015] Preferably, the bottom of the outer surface of the roller is in contact with the outer surface of the spraying module, and the crescent-shaped pieces are evenly distributed on the top of the outer surface of the connecting rod.

[0016] Preferably, an auxiliary module is provided at the bottom of the outer surface of the mixing tank, near the discharge port. The auxiliary module includes a housing, the outer surface of which is fixedly connected to the bottom of the outer surface of the mixing tank, the bottom of which is fixedly connected to the top of the discharge port, and a corrugated elastic element fixedly connected to the top of the inner surface of the housing. A whistle-shaped block is fixedly connected to the bottom of the corrugated elastic element, and a magnetic block is fixedly connected to the bottom of the whistle-shaped block. When mixing is complete and discharge is possible, the driving cylinder drives the mixing blades to rotate continuously, and the magnetic block is fixedly connected to the bottom of the mixing blades at the bottom of the driving cylinder. The block is driven to rotate in a circular motion. The block and the strong magnet are set as magnetic poles of the same name. When they are close, they generate a repulsive magnetic force. The magnetic force of the block compresses the wave-shaped elastic element. As the strong magnet moves away from the block, the repulsive magnetic force disappears. Under the elastic force of the wave-shaped elastic element, the whistle-shaped block returns to its original position. At this time, the whistle-shaped block impacts the bottom of the outer surface of the mixing tank, causing the bottom of the mixing tank to vibrate. The vibration is transmitted to the discharge port, thereby reducing the adhesion of the mixed concrete raw materials to the inner surface of the mixing tank and the inner surface of the discharge port, which helps to quickly discharge the material.

[0017] Preferably, two wavy elastic elements are provided, and the two wavy elastic elements are symmetrically arranged along the magnetic block. The outer surface of the whistle-shaped block is set as an arc surface, and the outer surface of the whistle-shaped block is in contact with the bottom of the outer surface of the mixing tank.

[0018] This invention provides a high-performance concrete mixing device for small box girder bridges. It has the following beneficial effects:

[0019] I. The high-performance concrete mixing equipment for this small box girder bridge utilizes a servo motor as its power source. Supported by a support column that extends into the interior of the drive cylinder, the drive cylinder is smoothly driven to rotate, preventing it from wobbling. This, in turn, causes the mixing components and the spreading module to rotate together, mixing the concrete raw materials in the mixing tank. The smooth operation not only reduces the resistance during mixing but also promotes thorough mixing of the raw materials.

[0020] II. The high-performance concrete mixing equipment used in this small box girder bridge, when the drive cylinder drives the mixing assembly to rotate in a circular motion, the rotating mixing blades agitate the concrete raw materials in the mixing tank, while the pressing rod remains stationary. At this time, the rotating semi-circular pressure block is subjected to the outward pressing force of the pressing rod, causing the mixing blades to move outward from the drive cylinder, and the hook piercing part moves with the mixing blades, and the reset spring is compressed. When the semi-circular pressure block is separated from the pressing rod, the pressing force disappears, and under the elastic force of the reset spring, the mixing blades drive the hook piercing part to reset. This reciprocating movement allows the mixing blades and hook piercing part to not only rotate in a circular motion, but also move downward in a straight line, increasing the angular direction of the concrete raw materials, and can promptly break up clumps of sand.

[0021] Third, the high-performance concrete mixing equipment used in this small box girder bridge utilizes a support frame to support the top cap, which is conical. At this time, the falling concrete material slides down the inclined surface of the top cap at a uniform speed, and the outlet leaks out some of the concrete material. As the dispensing blades rotate, the concrete material can be dispensed, thus ensuring that the concrete material falls evenly into the mixing tank. At the same time, the dispensing blades will contact the rollers on the discharge assembly, causing the dispensing blades and rollers to interact.

[0022] IV. The high-performance concrete mixing equipment used in this small box girder bridge utilizes the weight of the raw materials themselves, and the crescent blades break up the clumps of raw materials in a timely manner for pretreatment. At the same time, as the top cap drives the dispensing blades to rotate, it can not only dispense the falling raw materials, but also push the rollers upward through the contact between the rotating dispensing blades and the rollers. At this time, under the elastic support of the elastic strip, the connecting rod drives the crescent blades to move into the inside of the hopper, and the elastic strip is compressed. At this time, the concrete raw materials in the hopper are inserted through the triangular pieces and crescent blades together, and it is not easy for blockage to occur.

[0023] 5. The high-performance concrete mixing equipment used in this small box girder bridge utilizes a drive cylinder to continuously rotate the mixing blades, causing the magnetic block to rotate in a circular motion. The magnetic thrust of the magnetic block compresses the wave-shaped elastic element. As the strong magnet moves away from the magnetic block, the repulsive magnetic force disappears, and under the elastic force of the wave-shaped elastic element, the whistle-shaped block returns to its original position. At this point, the whistle-shaped block impacts the bottom of the mixing tank, causing vibration at the bottom of the mixing tank. This vibration is transmitted to the discharge port, thereby reducing the adhesion of the mixed concrete raw materials to the inner surface of the mixing tank and the inner surface of the discharge port, which helps to facilitate rapid discharge.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0034] First embodiment, such as Figures 1-6 As shown, the present invention provides a technical solution: a high-performance concrete mixing equipment for small box girder bridges, comprising:

[0035] The mixing tank 1 has a discharge port 2 installed at the bottom, which facilitates the discharge of the mixed concrete raw materials. A servo motor 3 is fixedly connected to the center of the top of the mixing tank 1. The servo motor 3 can be used as a power source. A support leg 4 is fixedly connected to the bottom of the mixing tank 1 near the edge. The support leg 4 can support the mixing tank 1, making the whole more stable.

[0036] Also includes:

[0037] The mixing mechanism 5 has a drive cylinder 51 rotatably connected to the top center of the inner surface of the mixing tank 1, and a support column 52 fixed to the bottom center of the inner surface of the mixing tank 1. The inner surface of the drive cylinder 51 is rotatably connected to the outer surface of the support column 52. A pressing rod 53 is fixedly connected to the outer surface of the support column 52 near the inner surface of the drive cylinder 51. A mixing component 54 is provided on the outer surface of the drive cylinder 51, and a dispensing module 55 is provided on the top of the drive cylinder 51. The mechanism uses a servo motor 3 as power and is supported by the support column 52, which extends into the interior of the drive cylinder 51. The drive cylinder 51 can rotate on the outer surface of the support column 52, so that the drive cylinder 51 is driven to rotate smoothly, making it less prone to shaking. This allows the mixing component 54 and the dispensing module 55 to rotate together in a circular motion to mix the concrete raw materials in the mixing tank 1. Under the smooth driving, not only can the resistance during mixing be reduced, but the mixing of raw materials can also be promoted.

[0038] The top of the drive cylinder 51 penetrates the top of the inner surface of the mixing tank 1 and extends to the outside. The top of the drive cylinder 51 is fixedly connected to the output end of the servo motor 3 through a coupling, so that the drive cylinder 51 can be driven to rotate by the servo motor 3. A rotation hole adapted to the support column 52 is opened at the center of the bottom of the drive cylinder 51 to facilitate the rotation of the drive cylinder 51.

[0039] The mixing assembly 54 includes a mixing blade 541. The outer surface end of the mixing blade 541 is slidably connected to the outer surface of the drive cylinder 51. A hook piercing element 542 is fixedly connected to the top of the outer surface of the mixing blade 541. A semi-circular pressure block 543 is fixedly connected to the outer surface end of the mixing blade 541 near the pressure bar 53. A reset spring strip 544 is fixedly connected to the top of the outer surface of the mixing blade 541 near the semi-circular pressure block 543. The top of the reset spring strip 544 is fixedly connected to the inner surface of the drive cylinder 51. A strong magnet 545 is fixedly connected to the bottom of the outer surface of the mixing blade 541 near the bottom of the drive cylinder 51. When the drive cylinder 51 rotates, it will drive the mixing assembly 54 to rotate in a circular motion. At this time, the rotating mixing blade 541 agitates the concrete raw materials in the mixing tank 1, and the support column 52 supports the pressure bar 53, so that the pressure bar 53 is in a position where... In a stationary state, as the mixing blade 541 rotates, the semi-circular pressure block 543 also rotates, and the outer edge of the semi-circular pressure block 543 is in contact with the outer surface of the pressing rod 53. At this time, the rotating semi-circular pressure block 543 is subjected to the outward pressing force of the pressing rod 53, causing the mixing blade 541 to move outward towards the drive cylinder 51. The hook piercing part 542 moves with the mixing blade 541, and the reset spring strip 544 is compressed. When the semi-circular pressure block 543 is separated from the pressing rod 53, the pressing force disappears, and under the elastic force of the reset spring strip 544, the mixing blade 541 drives the hook piercing part 542 to reset. This reciprocating movement allows the mixing blade 541 and the hook piercing part 542 to not only rotate in a circle, but also move downward in a straight line, increasing the angular direction of the concrete raw materials and timely breaking up the clumps of sand.

[0040] The curved piercing elements 542 are evenly distributed on the outer surface of the mixing blade 541. As the mixing blade 541 drives the curved piercing elements 542 to move back and forth, the curved piercing elements 542 together effectively break up the concrete raw materials adhering to each other in the mixing tank 1. At the same time, the mixing blade 541 is set at an angle, so that the top of the outer surface of the mixing blade 541 is an inclined surface. When the mixing blade 541 rotates, it can not only stir the concrete raw materials in the mixing tank 1, but also turn the raw materials over, so that the raw materials roll from bottom to top, and it is not easy for the raw materials to accumulate.

[0041] The stirring blades 541 are evenly distributed on the outer surface of the drive cylinder 51, which facilitates rapid stirring of the raw materials. The outer surface of the drive cylinder 51 is provided with sliding holes that are adapted to the outer surface end of the stirring blades 541, which facilitates the sliding of the stirring blades 541. The outer surface edge of the semi-circular pressure block 543 is in contact with the outer surface of the pressing rod 53.

[0042] The dispensing module 55 includes a support frame 551, with a top cap 552 fixedly connected to the top of the support frame 551. The top of the top cap 552 is fixedly connected to the top of the outer surface of the drive cylinder 51. A drain 553 is provided on the edge of the outer surface of the top cap 552. A dispensing blade 554 is fixedly connected to the top of the outer surface of the top cap 552 near the drain 553. When the drive cylinder 51 is driven, the dispensing module 55 is also driven to rotate. At this time, the support frame 551 supports the top cap 552, and the top cap 552 is conical. The falling concrete material slides down the inclined surface of the top cap 552 at a uniform speed, and the drain 553 leaks some of the concrete material. As the dispensing blade 554 rotates, the concrete material can be dispensed, so that the concrete material can fall evenly into the mixing tank 1. At the same time, the dispensing blade 554 will contact the roller 65 on the discharge assembly 6, so that the dispensing blade 554 and the roller 65 interact with each other. The structure is connected together by the interaction between the structures.

[0043] The openings 553 are evenly distributed on the outer edge of the top cap 552, increasing the number of openings 553 to facilitate the leakage of concrete materials. The spraying blades 554 are evenly distributed on the top of the outer surface of the top cap 552 to facilitate the spraying of materials. The openings 553 and the spraying blades 554 are arranged alternately.

[0044] Second embodiment, such as Figures 1-7 As shown, based on the first embodiment,

[0045] The feeding assembly 6 has a hopper 61 fixed to the top of the mixing tank 1 and near the servo motor 3. An elastic strip 62 is fixedly connected to the inner surface of the hopper 61 near the bottom. A triangular piece 63 is fixedly connected to the top of the outer surface of the elastic strip 62. A connecting rod 64 is fixedly connected to the bottom of the elastic strip 62. A roller 65 is installed at the bottom of the connecting rod 64. A crescent-shaped piece 66 is fixedly connected to the top of the outer surface of the connecting rod 64. Concrete raw materials are fed from the hopper 61, so that after entering the hopper 61, the concrete raw materials, by their own weight and passing through the crescent-shaped piece 66, are fed into the hopper. The raw materials are promptly broken up when they clump together for pretreatment. As the top cap 552 drives the dispensing blades 554 to rotate, it not only dispenses the falling raw materials, but also provides an upward pushing force to the rollers 65 through the contact between the rotating dispensing blades 554 and the rollers 65. At this time, under the elastic support of the elastic strip 62, the connecting rod 64 drives the crescent-shaped piece 66 to move into the hopper 61, and the elastic strip 62 is compressed. At this time, the concrete raw materials in the hopper 61 are inserted through the triangular piece 63 and the crescent-shaped piece 66 together, which makes it less likely to cause blockage and fully connects the structures together.

[0046] The hopper 61 is cone-shaped to facilitate the sliding of concrete raw materials falling onto the surface of the hopper 61. The outer surface of the elastic strip 62 is curved to facilitate bending and deformation under pressure. The tip of the triangular piece 63 is tilted upward.

[0047] The bottom of the outer surface of the roller 65 is in contact with the outer surface of the dispensing module 55, which makes it easy to drive the roller 65 to roll, thereby helping to apply upward pushing force, and the structure is less likely to get stuck. The crescent-shaped pieces 66 are evenly distributed on the top of the outer surface of the connecting rod 64.

[0048] The third embodiment, such as Figures 1-6 and Figure 8 As shown, based on the first embodiment,

[0049] An auxiliary module 7 is provided at the bottom of the outer surface of the mixing tank 1, near the discharge port 2. The auxiliary module 7 includes a housing 71. The outer surface of the housing 71 is fixedly connected to the bottom of the outer surface of the mixing tank 1, and the bottom of the housing 71 is fixedly connected to the top of the discharge port 2. A corrugated elastic element 72 is fixedly connected to the top of the inner surface of the housing 71. A whistle-shaped block 73 is fixedly connected to the bottom of the corrugated elastic element 72, and a magnetic block 74 is fixedly connected to the bottom of the whistle-shaped block 73. When the mixing is complete and the material is ready for discharge, the driving cylinder 51 drives the stirring blade 541 to rotate continuously. Combined with the magnetic block 74 fixed at the bottom of the stirring blade 541 at the bottom of the driving cylinder 51, the magnetic block 74 is activated. Block 74 is driven to rotate in a circle, and the magnetic block 74 and the strong magnet 545 are set as the same magnetic poles. When the two are close, they generate a repulsive magnetic force. The magnetic force of the magnetic block 74 compresses the wave-shaped elastic element 72. As the strong magnet 545 moves away from the magnetic block 74, the repulsive magnetic force disappears. Under the elastic force of the wave-shaped elastic element 72, the whistle-shaped block 73 is reset. At this time, the whistle-shaped block 73 impacts the bottom of the outer surface of the mixing tank 1, causing the bottom of the mixing tank 1 to vibrate. The vibration is transmitted to the discharge port 2, thereby reducing the adhesion of the mixed concrete raw materials to the inner surface of the mixing tank 1 and the inner surface of the discharge port 2, which helps to discharge the material quickly.

[0050] Two wavy elastic elements 72 are provided, and the two wavy elastic elements 72 are symmetrically arranged along the magnetic block 74 to facilitate elastic support for the whistle-shaped block 73. The outer surface of the whistle-shaped block 73 is set as an arc surface. The whistle-shaped block 73 is solid, which can increase its own weight. The outer surface of the whistle-shaped block 73 is in contact with the bottom of the outer surface of the mixing tank 1.

[0051] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
