Description

Technical Field

[0001] This invention relates to a concrete mixing equipment, specifically a concrete mixing equipment for the production and processing of precast concrete components, belonging to the field of precast concrete component processing technology. Background Technology

[0002] Precast concrete components are building components made in a factory using concrete as the basic material. These include beams, slabs, columns, and architectural finishing accessories. Precast concrete components refer to assembled concrete components that are completed before installation on the construction site. Common examples include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof trusses for industrial plants, culvert frames, and precast concrete piles for foundation treatment.

[0003] CN218286114U discloses a concrete mixing device, which includes a tank with an inlet pipe and an outlet pipe. A mixing paddle is provided inside the tank. A motor is provided on the tank. The output shaft of the motor is coaxially connected to the mixing paddle. The upper end of the inlet pipe is flared and detachably connected to an annular dust suction hood. The inner side of the dust suction hood is inclined downward and has several dust suction holes. A fan connected to the inside of the dust suction hood is installed at the bottom of the dust suction hood. A dust filter ring is embedded in the dust suction hood and is located between the dust suction holes and the fan.

[0004] In the above scheme, the stirring paddle is driven by a motor to rotate, and the stirring paddle stirs the material in the tank. This method of mixing the raw materials in one direction is relatively simple. Not only is the mixing effect of concrete raw materials poor, but it also increases the mixing time of concrete raw materials, thereby reducing the practicality of the device. Summary of the Invention

This addresses the issue that the existing technology uses a motor to drive the mixing paddle to rotate, which mixes the materials in the tank. This method of mixing raw materials in a single direction is simple, but it not only has poor mixing effect on concrete raw materials, but also increases the mixing time of concrete raw materials, thereby reducing the practicality of the device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a concrete mixing device for the production and processing of precast concrete components, comprising a support frame, a tank being disposed inside the support frame, two connecting pipes being fixedly connected to the outside of the tank, the two connecting pipes respectively penetrating the inside of the support frame on both sides and rotatably connected to the support frame, a first gear being fixedly connected to the outside of one of the connecting pipes, a first rack being meshed with the outside of the first gear, a moving block being fixedly connected to one end of the first rack, a turntable being disposed on one side of the moving block, a connecting rod being disposed between the turntable and the moving block, and a mixing assembly being disposed between the tank and the moving block.

[0009] Preferably, a convex groove is provided on the front side of the support frame, and a convex block is fixedly connected to the rear side of the moving block. The convex block is disposed inside the convex groove and slides in contact with the support frame. The way in which the convex block is disposed inside the convex groove and slides in contact with the support frame improves the stability of the reciprocating movement of the moving block.

[0010] Preferably, a rotating rod is fixedly connected to the rear side of the turntable, and a support plate is rotatably connected to the outer side of the rotating rod. The support plate is fixedly connected to the outer side of the support frame, and a drive motor is fixedly connected to the rear side of the support plate. The output end of the drive motor is fixedly connected to the rotating rod. The support plate provides support for the rotation of the rotating rod.

[0011] Preferably, a second round rod is fixedly connected to the front side of the turntable, a connecting block is fixedly connected to the outer side of the moving block, a first round rod is fixedly connected to the front side of the connecting block, and the two ends of the connecting rod are rotatably connected to the first round rod and the second round rod, respectively.

[0012] Preferably, the stirring assembly includes a rotating rod disposed inside the tank body, with both ends of the rotating rod passing through the inner side of the tank body and rotatably connected to the tank body. Two connecting pipes are respectively disposed at the outer ends of the rotating rod. A second gear is fixedly connected to the outer side of one end of the rotating rod, and a second rack is meshed with the outer side of the second gear. The second rack is fixedly connected to the outer side of the moving block.

[0013] Preferably, the stirring assembly further includes a protective frame, which is rotatably connected to the outside of the rotating rod and fixedly connected to the top of the tank. The protective frame contains two first bevel gears, both fixedly connected to the outside of the rotating rod. The protective frame provides rotational support for the two stirring rods. Two second bevel gears are meshed with the outside of each of the two first bevel gears, and stirring rods are fixedly connected to the bottom of each of the two second bevel gears. The bottom ends of both stirring rods pass through the bottom of the protective frame and are rotatably connected to it. The two first bevel gears have the same number of teeth, while the two second bevel gears have different numbers of teeth, meaning the two stirring rods rotate at a differential speed. Each stirring rod is equipped with multiple sets of stirring blades and multiple sets of crushing blades. Each set of stirring blades and each set of crushing blades... The stirring rod has multiple blades evenly arranged around its circumference on the same horizontal plane. Each group of stirring blades and each group of crushing blades has 3 to 5 blades. The stirring rod with a faster rotation speed has more crushing blade groups than stirring blade groups, and the stirring rod with a slower rotation speed has fewer crushing blade groups than stirring blade groups. The multiple groups of stirring blades and multiple groups of crushing blades are spaced apart along the vertical direction of the stirring rod, and the blades on two stirring rods are staggered in the vertical direction. The stirring rod is hollow, and the inside of the stirring rod is an airflow channel. An air pump is connected to the upper end of the stirring rod through an air inlet pipe. The air pump is located inside the protective frame. Multiple air holes are evenly arranged on the outer surface of the stirring rod, and the air holes are located between the multiple groups of crushing blades and stirring blades.

[0014] Preferably, four first springs are provided on the outer surface of the lower part of the tank body, the four first springs are evenly distributed on the outer circumference of the tank body, and the other ends of the four first springs are respectively fixedly connected to the four legs of the support frame; at the same time, multiple second springs are evenly distributed on the outer surface of the upper part of the tank body, the multiple second springs are evenly distributed on the outer circumference of the tank body, the other ends of the multiple second springs are free ends, and the free ends are all fixedly connected to steel balls. Magnet blocks are provided on the four legs of the support frame; preferably, the first springs are disc springs, the fourth springs are disc springs, the fifth ... The two springs are helical springs. The elastic modulus k1 of the first spring and the elastic modulus k2 of the second spring are related as follows: k1 = (3~5)k2. When the moving block moves back and forth, the first rack meshes with the first gear, thereby driving a connecting pipe to rotate back and forth, realizing the left and right swing of the tank. In order to improve the stability of the tank swing, the swing of the tank is limited by four first springs fixedly connected to the lower outer surface of the tank and the support frame legs. During the swing of the tank, the four first springs are compressed and stretched respectively. The elastic force of the first springs makes the tank more stable during the swing. This further improves the mixing effect of concrete raw materials. Simultaneously, multiple second springs are evenly arranged on the outer circumference of the upper part of the tank. Each second spring has a free end, and each free end is fixedly connected to a steel ball. When the tank is not swinging, the multiple second springs hang naturally under the gravity of the steel balls, and the steel balls contact the outer surface of the tank. When the tank swings left and right, the steel balls, under the tension of the second springs and the attraction of the magnets on the four legs of the support frame, will also swing irregularly with the tank and repeatedly impact the surface. On the outer surface of the body, the impact of the steel ball on the tank body shakes off the concrete material adhering to the inner wall of the tank, preventing excessive material adhering to the inner wall of the tank from causing blockage of the cavity; further, the relationship between the elastic modulus k1 of the first spring and the elastic modulus k2 of the second spring is defined as: k1 = (3~5)k2, that is, the first spring has a stronger ability to resist deformation, which is beneficial to maintaining the stability of the tank body when swinging, and the second spring has a larger deformation amplitude, which is beneficial to increasing the swing amplitude of the steel ball and its impact force on the tank body, which is beneficial to shaking off the material on the inner wall of the tank body.

[0015] Preferably, the first rack and the second rack have equal total lengths in the horizontal direction, the second rack has more teeth than the first rack, and the numerical relationship between the number of teeth m2 of the second rack and the number of teeth m1 of the first rack is: m2 = (5~8)m1, and the teeth on the second rack are divided into multiple segments with intervals between them; the moving block reciprocates in the horizontal direction under the drive of the turntable, causing the first rack and the second rack to move synchronously, driving the first gear to rotate through the first rack, thereby causing the connecting pipe and the tank to swing back and forth, and through the second rack The second gear drives the second gear to rotate, which in turn drives the stirring rod to rotate through the meshing of the first and second bevel gears, thereby mixing the concrete raw materials. By setting the number of teeth on the first and second racks, the oscillation speed of the tank and the rotation speed of the stirring rod can be reasonably set. To improve the stability of the tank, the oscillation speed should not be too high, while to improve the mixing effect of the concrete raw materials, the rotation speed of the stirring rod needs to be relatively fast. Therefore, the number of teeth on the second rack is set to be more than the number of teeth on the first rack. Specifically, the second... The numerical relationship between the number of teeth m2 of the rack and the number of teeth m1 of the first rack is: m2 = (5~8)m1. This ensures that, with a constant moving speed of the moving block, the rotation speed of the stirring rod is relatively fast, while the oscillation speed of the tank is relatively slow. That is, during one round trip of the tank's oscillation, the stirring rod rotates multiple times, thus simultaneously ensuring both the mixing effect of the raw materials and the overall stability of the equipment. Furthermore, during the mixing of concrete raw materials, to improve the mixing effect of various raw materials and enhance the strength of the mixed concrete, some additives are often added to the concrete raw materials. Continuous stirring can easily destroy the activity of the additives. Therefore, the teeth on the second rack are evenly divided into multiple segments, with intervals between the segments. During the reciprocating motion of the moving block, the first rack and the first gear remain engaged, causing the tank to continuously oscillate back and forth, while the second rack intermittently engages with the second gear, causing the stirring rod to rotate intermittently. This helps the additives in the concrete to fully contact and react with the raw materials, improving the mixing effect and strength of the concrete raw materials, while also preventing the activity of the additives from being destroyed.

[0016] This invention provides a concrete mixing equipment for the production and processing of precast concrete components, which has the following beneficial effects:

[0017] 1. This concrete mixing equipment for the production and processing of precast concrete components can reciprocate by pushing the moving block through the connecting rod, so that the first rack and the first gear mesh and connect, thereby driving one of the connecting pipes to reciprocate and rotate, so that the tank can swing left and right. At this time, with the cooperation of the mixing components, the mixing effect of concrete raw materials can be improved, and the mixing time of concrete raw materials can be shortened, thus improving the practicality of the device.

[0018] 2. In this concrete mixing equipment for the production and processing of precast concrete components, when the connecting rod can reciprocate to push the moving block, the second rack and the second gear mesh with each other, and the rotating rod drives the two first bevel gears to rotate. Through the meshing connection of the two first bevel gears and the two second bevel gears, the two mixing rods can perform mixing work inside the tank, thereby improving the mixing quality of concrete raw materials in coordination with the swing of the tank.

[0026] This invention provides a concrete mixing equipment for the production and processing of precast concrete components.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The system includes a support frame 1, inside which is a tank 2. Two connecting pipes 3 are fixedly connected to the outside of the tank 2. The two connecting pipes 3 pass through the inside of the support frame 1 on both sides and are rotatably connected to the support frame 1. A first gear 4 is fixedly connected to the outside of one of the connecting pipes 3. A first rack 5 is meshed with the outside of the first gear 4. A movable block 6 is fixedly connected to one end of the first rack 5. A convex groove is opened on the front side of the support frame 1. A convex block 7 is fixedly connected to the rear side of the movable block 6. The convex block 7 is set inside the convex groove and slides in contact with the support frame 1. A turntable 10 is provided on one side of the movable block 6. A rotating rod 13 is fixedly connected to the rear side, and a support plate is rotatably connected to the outside of the rotating rod 13. The support plate is fixedly connected to the outside of the support frame 1. A drive motor is fixedly connected to the rear side of the support plate. The output end of the drive motor is fixedly connected to the rotating rod 13. A connecting rod 12 is provided between the turntable 10 and the moving block 6. A second round rod 11 is fixedly connected to the front side of the turntable 10. A connecting block 8 is fixedly connected to the outside of the moving block 6. A first round rod 9 is fixedly connected to the front side of the connecting block 8. The two ends of the connecting rod 12 are rotatably connected to the first round rod 9 and the second round rod 11, respectively. A stirring assembly is provided between the tank 2 and the moving block 6.

[0028] Specifically, when mixing the concrete raw materials in tank 2, the drive motor is started first. The model of the drive motor is not specifically limited, but is based on the equipment. The output end of the drive motor drives the rotating rod 13 to rotate, so that the turntable 10 drives the second round rod 11 to make eccentric motion. The moving block 6 can be pushed back and forth through the connecting rod 12, so that the first rack 5 and the first gear 4 mesh and connect, thereby driving one of the connecting pipes 3 to rotate back and forth, so that tank 2 can swing left and right. At this time, with the cooperation of the mixing components, the mixing effect of concrete raw materials can be improved, and the mixing time of concrete raw materials can be shortened, thus improving the practicality of the device.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The stirring assembly includes a rotating rod 14, which is disposed inside the tank 2. Both ends of the rotating rod 14 pass through the inner side of the tank 2 and are rotatably connected to the tank 2. Two connecting pipes 3 are respectively disposed at the outer ends of the rotating rod 14. A second gear 19 is fixedly connected to the outer side of one end of the rotating rod 14. A second rack 20 is meshed with the outer side of the second gear 19. The second rack 20 is fixedly connected to the outer side of the moving block 6. The stirring assembly also includes a protective frame 15, which is rotatably connected to the outer side of the rotating rod 14 and fixedly connected to the inside of the tank 2. At the top of the protective frame 15, two first bevel gears 16 are provided inside. Both first bevel gears 16 are fixedly connected to the outside of the rotating rod 14. A second bevel gear 17 is meshed with the outside of each of the two first bevel gears 16. A stirring rod 18 is fixedly connected to the bottom of each of the two second bevel gears 17. The bottom ends of both stirring rods 18 pass through the bottom of the protective frame 15 and are rotatably connected to the protective frame 15. The two first bevel gears 16 have the same number of teeth, while the two second bevel gears 17 have different numbers of teeth. 8. Differential rotation: Both stirring rods 18 are equipped with multiple sets of stirring blades and multiple sets of crushing blades. Each set of stirring blades and each set of crushing blades consists of multiple blades evenly arranged around the circumference of the stirring rod 18 on the same horizontal plane. The number of blades in each set of stirring blades and each set of crushing blades is 3 to 5. The stirring rod 18 with a faster rotation speed has more sets of crushing blades than sets of stirring blades, while the stirring rod 18 with a slower rotation speed has fewer sets of crushing blades than sets of stirring blades. The multiple sets of stirring blades and multiple sets of crushing blades are spaced apart along the vertical direction of the stirring rod 18, and the sets of blades on the two stirring rods 18 are staggered in the vertical direction. The stirring rod 18 is hollow, and the interior of the stirring rod 18 is an airflow channel. Its upper end is connected to an air pump through an air inlet pipe. The air pump is located inside the protective frame. Multiple air holes are evenly arranged on the outer surface of the stirring rod 18, and the air holes are located between the multiple sets of crushing blades and stirring blades.

[0030] Specifically, when the connecting rod 12 reciprocates the moving block 6, the second rack 20 meshes with the second gear 19, and the rotating rod 14 drives the two first bevel gears 16 to rotate. Through the meshing of the two first bevel gears 16 with the two second bevel gears 17, the two stirring rods 18 perform stirring work inside the tank 2, thus improving the mixing quality of the concrete raw materials in conjunction with the oscillation of the tank 2. The staggered stirring blades and crushing blades on the two stirring rods 18 act simultaneously on the concrete, crushing large particles such as sand and gravel while mixing the concrete, thereby improving the mixing effect and avoiding dead zones in crushing and mixing. Since crushing blades are generally superior to stirring blades in terms of strength, hardness, and wear resistance, they are more suitable for rapid rotation, and rapid rotation of crushing blades can also improve the crushing effect. However, excessively high rotation speed of stirring blades can easily cause blade wear or even breakage. The mixing of raw materials is not conducive to proper mixing. Therefore, by setting the two second bevel gears with different numbers of teeth, the two mixing rods 18 are set to rotate at different speeds. The mixing rod 18 with a faster speed has more crushing blades than mixing blades, while the mixing rod 18 with a slower speed has fewer crushing blades than mixing blades. In this way, when the two mixing rods 18 rotate at different speeds, the concrete raw materials are simultaneously subjected to the action of the crushing blades and mixing blades on both mixing rods. This is beneficial for crushing large particles of sand and gravel in the raw materials, as well as for mixing various raw materials such as sand, cement, and dust, and it also avoids leaving any dead zones in crushing and mixing. At the same time, the air pump sends high-pressure air into the airflow channel inside the mixing rod 18 through the air inlet pipe and sprays it out through the air holes on the outer surface of the mixing rod 18. The high-pressure air further disperses the concrete raw materials, preventing them from clumping. It can also blow off the raw materials adhering to the mixing blades and crushing blades, further improving the mixing effect.

[0031] In another embodiment, four first springs 21 are provided on the outer surface of the lower part of the tank body 2. The four first springs 21 are evenly distributed on the outer circumference of the tank body 2, and the other ends of the four first springs 21 are respectively fixedly connected to the four legs of the support frame 1. At the same time, multiple second springs 22 are evenly distributed on the outer surface of the upper part of the tank body 2. The multiple second springs 22 are evenly distributed on the outer circumference of the tank body 2, and the other ends of the multiple second springs 22 are free ends, and the free ends are all fixedly connected to steel balls 23. Magnet blocks are provided on the four legs of the support frame 1. Preferably, the first springs 21 are... The disc spring and the second spring 22 are helical springs. The elastic modulus k1 of the first spring 21 and the elastic modulus k2 of the second spring 22 are related as follows: k1 = (3~5)k2. When the moving block moves back and forth, the first rack meshes with the first gear, thereby driving a connecting pipe to rotate back and forth, realizing the left and right swing of the tank 2. In order to improve the stability of the swing of the tank 2, the swing of the tank 2 is limited by four first springs 21 fixedly connected to the lower outer surface of the tank 2 and the legs of the support frame 1. During the swing of the tank 2, the four first springs 21 are compressed and stretched respectively. The elastic force of the first springs 21 makes the tank 2 swing. The process is more stable, further improving the mixing effect of concrete raw materials. Simultaneously, because multiple second springs 22 are evenly arranged on the outer circumference of the upper part of the tank 2, with each second spring 22 having a free end fixedly connected to a steel ball 23, when the tank 2 is not swinging, the multiple second springs 22 naturally droop under the gravity of the steel balls 23, and the multiple steel balls 23 contact the outer surface of the tank 2. When the tank 2 swings left and right, the multiple steel balls 23, under the tension of the second springs 22 and the attraction of the magnets on the four legs of the support frame 1, will also swing irregularly with the tank 2. Furthermore, the steel ball 23 will repeatedly impact the outer surface of the tank 2, and the impact of the steel ball 23 on the tank 2 will shake off the concrete adhering to the inner wall of the tank 2, preventing excessive material adhering to the inner wall of the tank 2 from causing blockage; the elastic modulus k1 of the first spring 21 and the elastic modulus k2 of the second spring 22 are further defined as: k1 = (3~5)k2, that is, the first spring 21 has a stronger ability to resist deformation, which is conducive to maintaining the stability of the tank 2 when swinging, and the second spring 22 has a larger deformation amplitude, which increases the swing amplitude of the steel ball 23 and its impact force on the tank 2, which is conducive to shaking off the material on the inner wall of the tank 2.

[0032] In another embodiment, the total length of the first rack 5 and the second rack 20 in the horizontal direction is equal. The number of teeth on the second rack 20 is greater than the number of teeth on the first rack 5. The numerical relationship between the number of teeth m2 of the second rack 20 and the number of teeth m1 of the first rack 5 is: m2 = (5~8)m1. The teeth on the second rack 20 are divided into multiple segments, and the segments are spaced apart. The moving block 6 reciprocates in the horizontal direction under the drive of the turntable 10, driving the first rack 5 and the second rack 20 to move synchronously. The first rack 5 drives the first gear 4 to rotate, thereby driving the connecting pipe and the tank 2 to reciprocate. The oscillation of the tank body 2, driven by the second rack 20, rotates the second gear 19, which in turn drives the stirring rod 18 to rotate through the meshing of the first and second bevel gears, thus mixing the concrete raw materials. By setting the number of teeth on the first rack 5 and the second rack 20, the oscillation rate of the tank body 2 and the rotation rate of the stirring rod 18 can be reasonably set. To improve the stability of the tank body 2, the oscillation rate should not be too high, while to improve the mixing effect of the concrete raw materials, the rotation rate of the stirring rod 18 needs to be relatively fast. Therefore, the number of teeth on the second rack 20 is set to be greater than that on the first rack 5. The number of teeth is greater. Specifically, the numerical relationship between the number of teeth m2 of the second rack 20 and the number of teeth m1 of the first rack 5 is: m2 = (5~8)m1. Thus, under the condition that the moving speed of the moving block 6 is constant, the rotation speed of the stirring rod 18 is faster, while the oscillation speed of the tank 2 is slower. That is, during the process of the tank 2 oscillating back and forth once, the stirring rod 18 rotates multiple times, thereby simultaneously taking into account the mixing effect of the raw materials and the overall stability of the equipment. At the same time, in the process of mixing concrete raw materials, in order to improve the mixing effect of various raw materials and enhance the strength of the mixed concrete, it is often added to the concrete raw materials. Adding additives to the material can easily damage their activity due to continuous stirring. Therefore, the teeth on the second rack 20 are divided into multiple segments with intervals between them. In this way, during the reciprocating motion of the moving block 6, the first rack 5 and the first gear 4 remain engaged, causing the tank 2 to continuously oscillate back and forth. Meanwhile, the second rack 20 intermittently engages with the second gear 19, causing the stirring rod 18 to rotate intermittently. This helps the additives in the concrete to fully contact and react with the raw materials, improving the mixing effect and strength of the concrete raw materials, while also preventing the activity of the additives from being destroyed.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
