Description

Technical Field

[0001] The utility model belongs to the field of mixing devices, and in particular relates to a concrete mixing device. Background Art

[0002] When mixing concrete, one of the more common construction devices is a concrete mixer. A concrete mixer is a machine that mixes cement, sand, gravel and water to make a concrete mixture. A general concrete mixer is mainly composed of a mixing drum, a water supply system, a transmission system support device, etc. Usually, the water supply system of the mixer is manually controlled. Since water needs to be continuously added to the mixing drum during the mixing process, long-term manual operation of water supply will appear to be very laborious and troublesome, and the amount of water added is not easy to control, which greatly increases the labor cost. After the mixing is completed, the concrete in the mixing drum needs to be removed, and the height of the mixing drum makes this operation extremely laborious, reducing work efficiency.

[0003] The Chinese patent with the announcement number CN220534558U discloses a concrete mixing device, which relates to the field of concrete mixing technology. In order to improve the concrete splashing caused by the mixing device during mixing, the splashed concrete will splash to the outlet end of the water pipe. As the concrete splashing on the water pipe increases, the water outlet efficiency of the water pipe is affected. It includes a mixing barrel and a bracket, a transmission shaft is installed at one end of the bracket, a transmission frame is installed on the surface of the transmission shaft, a stirring blade is connected to the bottom of the transmission frame, the transmission shaft is driven by a motor, a water pipe and a shielding component are arranged on one side of the mixing barrel; the shielding component includes a cylinder, the output end of the cylinder is connected to a driving block, a mounting block is arranged at the bottom of the driving block, and a shielding bin is installed on the mounting block. By sleeved the shielding bin on the outside of the outlet end of the water pipe, concrete splashed during the mixing process will not fall into the water pipe, thus avoiding affecting the subsequent water outlet efficiency of the water pipe and improving the mixing efficiency of the entire mixing device for concrete. The concrete mixing device in this application is sleeved on the outside of the outlet end of the water pipe through the shielding bin. Although the concrete splashed during the mixing process will not fall into the water pipe, a large amount of concrete will still splash during the mixing process, increasing the amount of concrete waste.

[0004] In view of this, the present utility model is proposed. Utility Model Content
