Description

Technical Field

[0001] This utility model belongs to the technical field of anti-segregation equipment, specifically a concrete anti-segregation device. Background Technology

[0002] Concrete, as an indispensable basic material in the modern construction industry, directly affects the strength, durability, and safety of engineering structures. Concrete is a multiphase composite material made by mixing cement, coarse and fine aggregates, water, and admixtures in a specific ratio. Ideally, the components should be evenly distributed to form a homogeneous and stable whole.

[0003] However, during the actual mixing, transportation, and pouring processes, concrete is highly susceptible to segregation. Segregation refers to the tendency of concrete components to separate under external forces or its own weight due to differences in particle size and density. Specifically, coarse aggregates sink while cement paste or water rises, disrupting the homogeneity of the mixture. Segregated concrete exhibits significantly deteriorated workability, mechanical properties, and durability, and is prone to defects such as honeycomb and pitting after pouring, seriously jeopardizing project quality.

[0004] Currently, preventing concrete segregation mainly relies on the mixing process. However, most existing mixing equipment uses a unidirectional rotation mixing method. The flow field formed by unidirectional mixing is simple, and the shear force on the material is insufficient, making it difficult to effectively break up aggregate agglomerates and creating hidden dangers for segregation. Utility Model Content

[0005] The purpose of this invention is to provide a concrete anti-segregation device to solve the problem that the existing technology mostly uses unidirectional rotation mixing, which results in a single flow field and insufficient shear force on the material, making it difficult to effectively break up aggregate agglomerates and creating hidden dangers for segregation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete anti-segregation device, comprising:

[0007] The support mechanism includes a support base and a drive component mounted on the support base;

[0008] A mixing mechanism includes a storage assembly rotatably connected to the support base, a set of mixing components rotatably connected to the storage assembly via bearings, a transmission assembly for driving the set of mixing components to rotate relative to each other, and the driving component for driving the storage assembly to rotate about its connection with the support base.

[0009] One of the mixing components includes a rotating shaft, with several stirring rods fixedly connected to the outside of the rotating shaft, and a driven bevel gear fixedly connected to one end of the rotating shaft;

[0010] The transmission assembly includes a driver and a transmission rod. The output end of the driver is fixedly connected to a driving gear, and the bottom of the transmission rod is fixedly connected to a driven gear. The driving gear and the driven gear mesh with each other. The top of the transmission rod is fixedly connected to a driving bevel gear, and the driving bevel gear meshes with two driven bevel gears.

[0011] Preferably, the storage assembly includes a storage cylinder, a feed hopper is fixedly connected to the top of the storage cylinder, a support leg is fixedly connected to the side of the storage cylinder near the bottom, a discharge port is fixedly connected to the side of the storage cylinder near the top, and the driver is a motor, which is fixedly connected to the bottom of the storage cylinder.

[0012] Preferably, a protective box is fixedly connected inside the storage cylinder, one end of the rotating shaft is rotatably connected to the inner wall of the storage cylinder through a bearing, and the other end of the rotating shaft extends into the interior of the protective box. Both the driven bevel gear and the driving bevel gear are located inside the protective box.

[0013] Preferably, a rotating frame is fixedly connected to the bottom of the storage cylinder near the support leg.

[0014] Preferably, the storage cylinder is rotatably connected to the support base via a rotating frame.

[0015] Preferably, the driving component is a hydraulic cylinder, with one end of the driving component rotatably connected to the support base and the other end of the driving component rotatably connected to the storage cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model starts the driver, and the output end of the driver drives the active gear to rotate. The active gear meshes with the driven gear, thereby driving the transmission rod to rotate. The active bevel gear at the top of the transmission rod rotates accordingly, driving the two driven bevel gears to rotate in opposite directions. Several stirring rods on the rotating shaft stir and mix the concrete in the storage cylinder. The relative rotation realizes the forced shearing and tumbling mixing of the concrete, effectively breaking up aggregate agglomeration and preventing segregation.

[0018] 2. When material needs to be discharged, the hydraulic cylinder extends and pushes the storage cylinder to make it flip. The hydraulic transmission allows for control of the thrust and speed, thereby achieving a slow and stable tilting of the storage cylinder, avoiding secondary segregation of concrete during discharge due to sudden tilting, and ensuring the quality of the discharged material.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown:

[0029] Example 1: This utility model provides a concrete anti-segregation device, comprising:

[0030] The support mechanism 1 includes a support base 11 and a drive component 12 mounted on the support base 11;

[0031] The mixing mechanism 2 includes a storage assembly 21 rotatably connected to the support base 11, a set of mixing assemblies 22 rotatably connected to the storage assembly 21 via bearings, a transmission assembly 23 for driving the set of mixing assemblies 22 to rotate relative to each other, and a driving member 12 for driving the storage assembly 21 to rotate around its connection with the support base 11.

[0032] Among them, a set of mixing components 22 includes a rotating shaft 221, a plurality of stirring rods 222 are fixedly connected to the outside of the rotating shaft 221, and a driven bevel gear 223 is fixedly connected to one end of the rotating shaft 221;

[0033] The transmission assembly 23 includes a driver 231 and a transmission rod 232. The output end of the driver 231 is fixedly connected to a drive gear 233. The bottom of the transmission rod 232 is fixedly connected to a driven gear 234. The drive gear 233 and the driven gear 234 mesh with each other. The top of the transmission rod 232 is fixedly connected to a drive bevel gear 235. The drive bevel gear 235 meshes with two driven bevel gears 223.

[0034] First, the driver 231 is started, which drives the drive gear 233 at its output end to rotate. The drive gear 233 drives the driven gear 234 to rotate, thereby driving the transmission rod 232 to rotate. The drive bevel gear 235 at the top of the transmission rod 232 rotates accordingly. Since the drive bevel gear 235 meshes with two driven bevel gears 223 at the same time, it drives the two rotating shafts 221 and several stirring rods 222 on them to rotate relative to each other in the storage assembly 21. This relative motion can generate strong shear force, which improves the mixing uniformity of concrete and effectively prevents segregation from the source. After mixing is completed, the drive component 12 is started. The drive component 12 drives the entire storage assembly 21 to rotate around its connection with the support base 11 so as to discharge the material.

[0035] 1. In one embodiment of the present invention, the storage assembly 21 includes a storage cylinder 211, the top of the storage cylinder 211 is fixedly connected to a feed hopper 212, a support leg 213 is fixedly connected to the side of the storage cylinder 211 near the bottom, and a discharge port 214 is fixedly connected to the side of the storage cylinder 211 near the top. The driver 231 is a motor and is fixedly connected to the bottom of the storage cylinder 211.

[0036] The concrete raw materials are added through the feed hopper 212, and the mixed concrete is discharged from the discharge port 214 during discharge.

[0037] 2. In one embodiment of the present invention, a protective box 215 is fixedly connected inside the storage cylinder 211. One end of the rotating shaft 221 is rotatably connected to the inner wall of the storage cylinder 211 through a bearing, and the other end of the rotating shaft 221 extends into the interior of the protective box 215. The driven bevel gear 223 and the driving bevel gear 235 are both located inside the protective box 215.

[0038] Among them, the protective box 215 effectively isolates the driven bevel gear 223 and the driving bevel gear 235 from the erosion, wear and jamming of concrete slurry and hard aggregate, ensuring the smoothness and reliability of transmission, and significantly reducing the failure rate and maintenance cost of the equipment.

[0039] 3. In one embodiment of the present invention, a rotating frame 216 is fixedly connected to the bottom of the storage cylinder 211 near the support leg 213.

[0040] Among them, the rotating frame 216 serves as a tilting hub, providing a sturdy and reliable rotation fulcrum for the storage cylinder 211.

[0041] 4. In one embodiment of the present invention, the storage cylinder 211 is rotatably connected to the support base 11 via the rotating frame 216.

[0042] The storage cylinder 211 is rotatably connected to the support base 11 through the rotating frame 216, which allows the storage cylinder 211 to rotate around the axis of the rotating frame 216.

[0043] Example 2: This example is basically the same as the previous example, except that the driving component 12 is a hydraulic cylinder, one end of the driving component 12 is rotatably connected to the support base 11, and the other end of the driving component 12 is rotatably connected to the storage cylinder 211.

[0044] When material needs to be discharged, the hydraulic cylinder extends and pushes the storage cylinder 211 to flip it. The hydraulic transmission allows for control of the thrust and speed, thereby achieving a slow and smooth tilting of the storage cylinder 211. This avoids secondary segregation of the concrete during discharge due to sudden tilting, ensuring the quality of the discharged material.

[0045] Application Process: The operator pours concrete raw materials (such as cement, sand, aggregate, and water) into the storage cylinder 211 through the feed hopper 212. The driver 231 is activated, and its output drives the drive gear 233 to rotate. The drive gear 233 meshes with the driven gear 234, thereby driving the transmission rod 232 to rotate. The drive bevel gear 235 at the top of the transmission rod 232 rotates accordingly, driving two driven bevel gears 223 to rotate in opposite directions. Several stirring rods 222 on the rotating shaft 221 stir and mix the concrete inside the storage cylinder 211. This relative rotation achieves forced shearing and tumbling mixing of the concrete, effectively breaking up aggregate agglomeration and preventing segregation. Both the driven bevel gears 223 and the drive bevel gears 235 are located within the protective box 215 to prevent... Concrete intrusion protects the driven bevel gear 223 and the driving bevel gear 235 from concrete wear and corrosion, extending the service life of the transmission components and reducing maintenance frequency. During the mixing process, the drive 231 runs continuously, and the shaft 221 of the mixing component 22 and the stirring rod 222 keep rotating, keeping the concrete in motion. Even if the concrete is left to stand for a short time, the stable drive of the transmission component 23 can prevent heavy aggregates from sinking or light slurry from floating. After the mixture is evenly mixed, the operator starts the drive component 12, which extends and pushes the storage cylinder 211 to rotate around the connection between the rotating frame 216 and the support base 11. The storage cylinder 211 gradually tilts, and the mixed concrete is slowly discharged from the discharge port 214. The support leg 213 provides support, making the discharge more stable.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
