[0002] Concrete mixing is an operation of uniformly mixing materials such as cement, lime, and water. Concrete mixing is divided into two types: manual mixing and mechanical mixing. In construction sites, manual mixing is suitable for small-scale concrete operations and other operation occasions that require a more flexible mixing scheme. In such cases, the use of mechanical mixer equipment has a high cost, and the handling and movement of the mixing equipment are relatively inconvenient.

[0003] In operation occasions that require small-scale concrete operations and other operation occasions that require a more flexible mixing scheme, although manual mixing is relatively convenient, the manual mixing speed is slow, requiring a large amount of manpower and time, and the components of the mixed concrete are relatively uneven. Conventional mixing machines are relatively bulky, not easy to transport, and inconvenient to operate and use. In the case of small-scale concrete operations and the need for a flexible operation space, there is a problem that it is impossible to quickly mix and evenly mix a small amount of concrete to complete the mixing operation. For this reason, this application proposes a concrete mixing device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a concrete mixing device to solve the problem that in the case of small-scale concrete operations and the need for a flexible operation space, it is impossible to quickly mix and evenly mix a small amount of concrete as mentioned in the above background art.

Detailed implementation mode

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a concrete mixing device, including a mixing barrel 4, a mixing mechanism and a moving frame. The mixing barrel 4 is combined with the support arm 221 by a conventional method, and the mixing barrel 4 is in a suspended state. The moving frame includes a bottom plate 1, a fixed arm 2 vertically installed at the side position of the bottom plate 1, a stabilizing plate 21 and a cross arm 22 installed inside the fixed arm 2, a support platform 211 perpendicular to the side of the stabilizing plate 21 and a support arm 221 perpendicular to the side of the cross arm 22. The fixed arm 2 is combined with the bottom plate 1 by a conventional method, the fixed arm 2 is combined with the stabilizing plate 21 and the cross arm 22 by a conventional method, the stabilizing plate 21 is combined with the support platform 211 and the cross arm 22 is combined with the support arm 221 by a conventional method. The bottom plate 1 is provided with moving rollers, which can quickly move the concrete mixing device in this application; the mixing mechanism includes a mixing motor 31 installed on the support platform 211 and a mixing shaft 32 with the bottom end extending into the mixing barrel 4. The output shaft of the mixing motor 31 is connected to the top end of the mixing shaft 32. When the mixing motor 31 operates, the mixing shaft 32 is driven to rotate, and the mixing blades on the mixing shaft 32 agitate the mixed raw materials in the mixing barrel 4 to make them evenly mixed into concrete; a blocking component is provided on the side of the mixing barrel 4. The blocking component includes a blocking plate 61 that seals the side opening of the mixing barrel 4, a discharge pipe 62 connected to the top end of the blocking plate 61, and a connecting block 63 installed between the blocking plate 61 and the discharge pipe 62. The connecting block 63 is combined with the blocking plate 61 and the discharge pipe 62 by a conventional method. The blocking plate 61 blocks the side opening of the mixing barrel 4 to prevent the concrete raw materials in the mixing barrel 4 from leaking out. When the blocking plate 61 moves downward, the side opening of the mixing barrel 4 is exposed, and the concrete in the mixing barrel 4 leaks out and flows into the discharge pipe 62. A concrete storage barrel can be used to receive the concrete flowing down from the discharge pipe 62, which is convenient for operation and use; limiting blocks 41 and connecting plates 42 are provided on the surface of the mixing barrel 4. The limiting blocks 41 and the connecting plates 42 are installed on the outer surface of the mixing barrel 4 by a conventional method. A sliding rod 611 passing through the limiting block 41 is provided on the blocking plate 61, and a limiting rod 421 is rotatably connected to the connecting plate 42. The sliding rod 611 is limited by the limiting block 41 to make the blocking plate 61 move vertically, and the limiting rod 421 rotates to limit the sliding rod 611, so that the sliding rod 611 and the blocking plate 61 are stabilized.

[0020] In this embodiment, the mixing barrel 4 includes a feeding hopper that is wide at the top and narrow at the bottom distributed at the top position and a mixing cylinder with a side opening distributed at the bottom position. The blocking plate 61 fits with the side of the mixing cylinder, and the blocking plate 61 blocks the side opening of the mixing barrel 4 to prevent the concrete raw materials in the mixing barrel 4 from leaking out.

[0021] In this embodiment, the sliding rod 611 with an "L" - shaped structure is slidably connected to the limiting block 41. A clamping groove cooperating with the limiting rod 421 is provided on the sliding rod 611. The sliding rod 611 is limited by the limiting block 41, causing the sealing plate 61 to move vertically, and the limiting rod 421 rotates. The limiting rod 421 limits the sliding rod 611, making the sliding rod 611 and the sealing plate 61 stable.

[0022] In this embodiment, the discharge pipe 62 includes an inclined part and a horizontal part. The cross - section of the discharge pipe 62 is a "U" - shaped structure. The side of the discharge pipe 62 blocks the concrete, preventing the concrete from leaking from the side of the discharge pipe 62.

[0023] In this embodiment, the surface of the bottom plate 1 is provided with a moving member and a lifting assembly. The moving member includes guide rails 11 symmetrically installed on the bottom plate 1 and moving sliders 12 slidably connected to the guide rails 11. The guide rails 11 and the bottom plate 1 are combined by conventional methods. The lifting assembly includes a column 51 connected to the moving slider 12, an adjusting screw 52 passing through the top end of the column 51, and a lifting slider 53 installed inside the column 51. The adjusting screw 52 passes through the lifting slider 53. The moving slider 12 and the column 51 are combined by conventional methods. The moving slider 12 moves along the length direction of the guide rail 11, facilitating the adjustment of the position of the column 51. When the adjusting screw 52 rotates, the lifting slider 53 moves up and down, and the height positions of the lifting slider 53, the sliding column 631, the connecting block 63, the sealing plate 61, and the discharge pipe 62 can be changed.

[0024] In this embodiment, a limiting ear 531 passing through the column 51 is provided on the side of the lifting slider 53. The limiting ear 531 is slidably connected to the column 51. The limiting ear 531 and the lifting slider 53 are combined by conventional methods. A split hanging rod 532 passes through the limiting ear 531. A sliding column 631 is slidably connected to the connecting block 63. Through - holes for the end of the "U" - shaped hanging rod 532 to pass through are provided on the limiting ear 531 and the sliding column 631. The end of the hanging rod 532 passes through the limiting ear 531 and the sliding column 631, making the limiting ear 531 and the sliding column 631 form a whole. A rectangular groove cooperating with the limiting ear 531 is provided on the side of the bottom end of the sliding column 631. The sliding column 631 is engaged with the limiting ear 531, and the combination of the sliding column 631 and the limiting ear 531 is stable.

[0025] The working principle and usage process of the present utility model:

[0026] When mixing concrete, mixing materials such as cement, lime, and water are placed inside the mixing barrel 4. The mixing motor 31 operates, driving the mixing shaft 32 to rotate. The mixing blades on the mixing shaft 32 stir the mixed raw materials in the mixing barrel 4, making them evenly mixed into concrete, which is convenient for mixing.

[0027] When the blocking plate 61 moves downward, the side opening of the mixing barrel 4 is exposed, and the concrete in the mixing barrel 4 leaks out and flows towards the discharge pipeline 62. A concrete receiving barrel can be used to receive the concrete flowing down from the discharge pipeline 62, which is convenient for operation and use.

[0028] When the amount of concrete in the mixing barrel 4 is large and the blocking plate 61 cannot move downward smoothly, the sliding column 631 engages with the limiting ear 531. The combination of the sliding column 631 and the limiting ear 531 is stable. The end of the hanging rod 532 penetrates through the limiting ear 531 and the sliding column 631, making the limiting ear 531 and the sliding column 631 form an integral body. By rotating the adjusting screw 52, the lifting slider 53 moves up and down, and the height positions of the lifting slider 53, the sliding column 631, the connecting block 63, the blocking plate 61, and the discharge pipeline 62 can be changed, so that the concrete in the mixing barrel 4 leaks down.

[0029] The concrete mixing device in this application has a simple structure and can be used in the case of small-scale concrete operation and the need for a flexible working space, and can quickly mix a small amount of concrete evenly.

[0030] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
