Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a concrete quantitative proportioning device. Background Art

[0002] Concrete mix ratio refers to the proportional relationship between the various components (cement, water, sand, gravel, etc.) in concrete. The concrete mix ratio is usually determined by the quality of the cement as a benchmark to determine the quality of the other components. The concrete mix ratio may vary depending on local standards, material properties, and engineering requirements. For example, patent publication number CN 116291569A discloses a concrete spraying device with a material quantitative proportioning function. The upper side of the mounting frame is fixedly connected to three laterally equidistant storage bins, the outer sides of which are provided with a vibration motor, and the lower sides of the three storage bins are fixedly connected to a mixing box located directly above the mixing drum. The materials in the multiple storage bins are fed into the mixing box for mixing. However, the storage bins can only be used to store materials. When multiple materials need to be initially mixed in a storage bin, manual stirring and mixing is required, which reduces production efficiency. Utility Model Content

[0018] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0019] like Figures 1 to 6As shown, a concrete quantitative proportioning device of this embodiment includes a mixing drum 1 and several material drums 2. The several material drums 2 are connected to the mixing drum 1, and the materials in the material drums 2 are fed into the mixing drum 1 for mixing. A stirring assembly 3 is provided on one side of the several material drums 2. The stirring assembly 3 includes a mounting base 31, an agitator 32, a drive motor 33, a lifting rod 34, a rotating wheel 35, and a drive wheel 36. The agitator 32 and the drive motor 33 are connected by a transmission belt 37 and are mounted on the mounting base 31. The agitator 32 is vertically arranged. The top of the lifting rod 34 is arranged on the rotating wheel 35. The side of the rotating wheel 35 is provided with a tooth portion 351. The mounting seat 31 is arranged on the top of the rotating wheel 35. The driving wheel 36 is arranged on the driving rod 38. The driving wheel 36 is meshed with the rotating wheel 35. The driving rod 38 is inserted into the connecting portion 341 of the lifting rod 34. The driving rod 38 is connected to the sleeve 39. The driving rod 38 moves up and down in the sleeve 39. The driving rod 38 and the sleeve 39 are connected by a connecting mechanism. The sleeve 39 drives the driving rod 38 to rotate. The sleeve 39 is connected to the power device 4, which drives the sleeve 39 to rotate. The power device 4 can be a motor. In the above technical solution, the material in the barrel 2 is stirred by the stirring assembly 3. Before stirring, the lifting rod 34 is raised. The lifting rod 34 is connected to the cylinder and driven by the cylinder. The bottom of the stirrer 32 is higher than the barrel 2. The driving wheel 36 drives the rotating wheel 35 to rotate, thereby rotating the mounting base 31, so that the stirrer 32 can be moved between multiple barrels 2, thereby stirring the materials in different barrels 2. Through the above technical solution, multiple barrels can be stirred by a single stirring assembly, which facilitates operation and improves processing efficiency.

[0020] In this embodiment, the driving rod 38 and the sleeve 39 are connected by a keyway, and a key 40 is set between the driving rod 38 and the sleeve 39.
