Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, in particular to a self-circulating cooling concrete mixing device. Background Art

[0002] Concrete mixing plants are essential equipment in fields such as construction and road engineering, and their performance directly impacts concrete quality and construction efficiency. Existing concrete mixing plants typically utilize a fixed drum. After mixing, the drum must be tilted to pour the concrete, either with the aid of external lifting equipment or manual handling. This cumbersome operation poses safety risks and can lead to concrete spillage. Furthermore, the drum tilting angle is difficult to precisely control, which can easily result in concrete residue and material waste.

[0003] In terms of mixing uniformity, some mixing devices have improperly designed mixing components, with excessive distance between the mixing blades and the inner wall of the mixing drum. This results in inadequate mixing of the concrete, affecting its strength and durability. Furthermore, frictional heat generated during mixing can be a problem, and conventional devices offer poor heat dissipation. High temperatures can cause the concrete to prematurely solidify, reducing its performance and even rendering it useless. Summary of the Invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and propose a frame for supporting a storage assembly. The storage assembly can rotate on the frame. After the storage assembly rotates, it can tilt so that the opening is tilted, which is convenient for pouring out the mixed concrete. The stirring assembly is rotatably arranged in the storage assembly. The stirring assembly is driven to rotate by the driving assembly. The stirring assembly can stir the concrete in the storage assembly so that the concrete is mixed more evenly. The heat dissipation of the storage assembly is driven by the heat sink, and at the same time, the heat sink is stuck on the limit assembly to prevent the storage assembly from rotating, so that during normal use, the opening of the storage assembly remains in a vertical upward state. When the concrete in the storage assembly needs to be poured out, the limit assembly is opened to separate the limit assembly from the heat sink, so that the storage assembly can rotate, so that the concrete in the storage assembly can be poured out, thereby conveniently pouring out the concrete in the self-circulating cooling concrete mixing device.

[0005] The technical solution of the present invention is: a self-circulating cooling concrete mixing device, including a frame, a storage assembly, a stirring assembly, a drive assembly and a heat sink, the storage assembly is rotatably arranged on the frame, the stirring assembly is rotatably arranged in the storage assembly, the drive assembly is used to drive the stirring assembly to rotate, the heat sink is arranged on the storage assembly, and the heat sink cooperates with the limit assembly to limit the rotation of the storage assembly.

[0006] Preferably, the storage assembly includes a mixing barrel and a lower hopper, the mixing barrel is rotatably arranged on a frame, and the lower hopper is arranged at the open end of the mixing barrel for guiding the poured concrete.

[0007] Preferably, the stirring assembly includes a rotating shaft, a connecting frame and a stirring blade, the rotating shaft is rotatably connected to the stirring barrel, the connecting frame is arranged on the rotating shaft, and the stirring blade is detachably connected to the connecting frame.

[0008] Preferably, the driving assembly includes a driving motor, a driving pulley, a transmission belt and a driven pulley, the driving pulley is connected to the output shaft of the driving motor, the driven pulley is arranged on the rotating shaft, and the driving pulley drives the driven pulley to rotate through the transmission belt.

[0009] Preferably, the driven pulley further includes a belt connecting wheel, spokes and a connecting wheel, the belt connecting wheel is arranged on the transmission belt, the spokes connect the belt connecting wheel and the connecting wheel, the connecting wheel is connected to the rotating shaft, and the blades of the connecting wheel have an inclination angle.

[0010] Preferably, the limiting assembly includes a plug-in post, a push block, an elastic member and a handle. The plug-in post is slidably arranged on the frame, the push block is connected to the plug-in post, the elastic member is used to push the push block to insert the plug-in post into the gap of the heat sink, and the handle is used to pull the plug-in post to separate it from the heat sink.

[0011] Preferably, the mixing barrel is provided with a clamping post, and the frame is provided with a clamping groove matched with the clamping post, so as to limit the rotation angle of the mixing barrel.

[0012] Preferably, the heat sinks are evenly distributed on the outer side wall of the storage assembly, and the spacing between adjacent heat sinks is adapted to the diameter of the plug-in column.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: In the present invention, the frame is used to support the storage assembly, and the storage assembly can rotate on the frame. After the storage assembly rotates, it can tilt so that the opening is tilted, which makes it convenient to pour out the mixed concrete. The stirring assembly is rotatably arranged in the storage assembly, and the stirring assembly is driven to rotate by the driving assembly. The stirring assembly can stir the concrete in the storage assembly so that the concrete is mixed more evenly. The heat dissipation of the storage assembly is driven by the heat sink, and at the same time, the heat sink is stuck on the limit assembly to prevent the storage assembly from rotating, so that during normal use, the opening of the storage assembly remains in a vertical upward state. When the concrete in the storage assembly needs to be poured out, the limit assembly is opened to separate the limit assembly from the heat sink, so that the storage assembly can be rotated, and the concrete in the storage assembly can be poured out, thereby conveniently pouring out the concrete.

[0014] The mixing barrel is rotatably arranged on the frame, so that the mixing barrel can rotate around the frame, and the rotation axis is the rotation axis. When the mixing barrel is tilted, the unloading hopper can conveniently unload the material, guide and collect the concrete, and avoid spilling all the concrete.

[0015] When the driving assembly drives the rotating shaft to rotate, the rotating shaft drives the connecting frame to rotate, and the connecting frame drives the stirring blade to rotate. The stirring blade can stir the concrete in the storage assembly, so that the concrete can be stirred more evenly. The stirring blade and the connecting frame are detachably connected and can be replaced after the stirring blade is damaged. They are connected by bolts, so that if the stirring blade is damaged, there is no need to replace the entire stirring assembly.

[0016] The driving motor drives the active pulley to rotate, and the active pulley drives the driven pulley to rotate through the transmission belt, and the driven pulley is arranged on the rotating shaft, so as to drive the rotating shaft to rotate, mixing the concrete in the storage component. After the mixing is completed.

[0017] When concrete is mixed, heat is generated, and the heat is transferred to the heat sink through the storage component. The heat sink increases the contact area with the air, so that the heat can be better dissipated. The driving component includes a belt connecting wheel arranged on the transmission belt, a spoke arranged on the belt connecting wheel, and a connecting wheel arranged on the spoke and connected to the rotating shaft. The blades of the connecting wheel have an inclination angle, so that when the driven pulley rotates, wind force is generated, thereby accelerating the air circulation speed on the heat sink around the storage component, and better cooling treatment can be performed. The driving component can cool the driving motor, thereby avoiding failure of the driving motor due to overheating.

[0018] The clamping post is set on the mixing barrel. When the mixing barrel is in a vertical state, that is, when the opening is facing upward, the clamping post is clamped on the frame, which can prevent the mixing barrel from rotating too much and ensure the stability of the mixing barrel.

[0019] During normal use, the plug-in column is slidably set on the frame, the elastic part pushes the push block to move, and the push block pushes the plug-in column to move, so that the plug-in column is inserted between the two heat sinks, thereby fixing the mixing barrel through the heat sink to prevent the mixing barrel from rotating, so that the mixing barrel is stuck in the current position to ensure stability.

[0020] When the concrete in the mixing barrel needs to be poured out, the handle is pulled, so that the handle drives the plug-in column to move, so that the plug-in column is separated from the heat sink, and the limit on the heat sink is released, so that the mixing barrel can be rotated. When the mixing barrel is turned over, the lower hopper can be driven to move, so that the lower hopper is tilted, and the concrete in the mixing barrel is guided so that the concrete can flow out of the mixing barrel for easy collection. The concrete is cooled by the heat sink, which can prevent the concrete from being unusable due to excessive temperature. When the concrete in the mixing barrel needs to be poured out, the handle is pulled, so that the handle drives the plug-in column to move, so that the plug-in column is separated from the heat sink, and the limit of the heat sink is released, so that the mixing barrel can be rotated. When the mixing barrel is turned over, the lower hopper can be driven to move, so that the lower hopper is tilted, and the concrete in the mixing barrel is guided so that the concrete can flow out of the mixing barrel for easy collection. Cooling the concrete by the heat sink can prevent the concrete from being unusable due to excessive stability. Tipping is convenient and stable: the mixing barrel of the storage component is rotatably set on the frame. During normal use, the plug-in column of the limit component is inserted into the gap of the heat sink. The heat sink and the limit component are clamped together to keep the opening of the mixing barrel vertically upward, ensuring a stable mixing process. When tipping, pull the handle to separate the plug-in column from the heat sink. After releasing the limit, you can rotate the mixing barrel to tilt its opening, and cooperate with the lower hopper to realize smooth discharge of concrete to avoid spillage. Even mixing and easy maintenance: The stirring blades of the stirring assembly are connected to the connecting frame with detachable bolts. When the stirring blades are damaged, there is no need to replace the entire stirring assembly, reducing maintenance costs. The drive motor of the drive assembly drives the driven pulley through the active pulley and transmission belt, which in turn drives the rotating shaft to rotate, so that the stirring blades can fully stir the concrete and ensure uniform mixing. Double heat dissipation design: The heat sinks are evenly distributed on the outer wall of the storage assembly, increasing the contact area between the storage assembly and the air, improving the heat dissipation effect during the concrete mixing process, and avoiding the impact of excessive temperature on the performance of the concrete. At the same time, the blades of the connecting wheel in the drive assembly have an inclination angle. When the driven pulley rotates, it drives the connecting wheel to rotate to generate wind force, accelerate the air circulation around the storage assembly, and simultaneously cool the storage assembly and the drive motor, extending the service life of the equipment.

[0034] Preferably, a clamping column 6 is provided on the mixing barrel 201 , and a clamping groove cooperating with the clamping column 6 is provided on the frame 1 for limiting the rotation angle of the mixing barrel 201 .

[0035] Preferably, the heat sinks 5 are evenly distributed on the outer wall of the storage assembly 2 , and the spacing between adjacent heat sinks 5 is adapted to the diameter of the plug-in column 701 .

[0036] In this embodiment, the frame 1 is used to support the storage component 2, and the storage component 2 can rotate on the frame 1. After the storage component 2 rotates, it can tilt so that the opening is tilted, which is convenient for pouring out the mixed concrete. The stirring component 3 is rotatably arranged in the storage component 2, and the stirring component 3 is driven to rotate by the driving component 4. The stirring component 3 can stir the concrete in the storage component 2 so that the concrete is mixed more evenly. The heat dissipation of the storage component 2 is driven by the heat sink 5, and at the same time, the heat sink 5 is stuck on the limit component 7 to prevent the storage component 2 from rotating, so that during normal use, the opening of the storage component 2 remains in a vertical upward state.

[0037] The mixing barrel 201 is rotatably arranged on the frame 1 so that the mixing barrel 201 can rotate around the frame 1, and the rotation axis is the rotation axis 301. When the mixing barrel 201 is tilted, the discharge hopper 202 can conveniently discharge the concrete, guide and collect the concrete, and avoid spilling all the concrete.

[0038] When the driving component 4 drives the rotating shaft 301 to rotate, the rotating shaft 301 drives the connecting frame 302 to rotate, and the connecting frame 302 drives the stirring blade 303 to rotate. The stirring blade 303 can stir the concrete in the storage component 2, so that the concrete can be stirred more evenly. The stirring blade 303 and the connecting frame 302 are detachably connected and can be replaced after the stirring blade 303 is damaged. They are connected by bolts, so that if the stirring blade 303 is damaged, there is no need to replace the entire stirring component 3.

The concrete is cooled by the heat sink 5, which can prevent the concrete from being unusable due to excessive stability. The pouring is convenient and stable: the mixing barrel 201 of the storage component 2 is rotatably set on the frame 1. During normal use, the plug-in column 701 of the limit component 7 is inserted into the gap of the heat sink 5.

The driving motor 401 of the driving assembly 4 drives the driven pulley 404 to rotate through the active pulley 402 and the transmission belt 403, thereby driving the rotating shaft 301 to rotate, so that the stirring blades 303 fully stir the concrete to ensure mixing uniformity. Double heat dissipation design: The heat sinks 5 are evenly distributed on the outer wall of the storage assembly 2, increasing the contact area between the storage assembly 2 and the air, improving the heat dissipation effect during the concrete mixing process, and avoiding the impact of high temperature on the concrete performance; at the same time, the blades of the connecting wheel 4041 in the drive assembly 4 have an inclination angle, which drives the connecting wheel 4041 to rotate when the driven pulley 404 rotates to generate wind force, accelerate the air circulation around the storage assembly 2, and synchronously cool the storage assembly 2 and the drive motor 401, thereby extending the service life of the equipment.
