Description

Technical Field

[0001] The utility model relates to the field of concrete mixers, in particular to a high-efficiency concrete mixer. Background Art

[0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water to make a concrete mixture. The concrete mixer is small in size, easy to carry and hold, and can be used flexibly.

[0003] However, there are some shortcomings in the current concrete mixers. When the concrete mixer is in use, a protective plate is installed on the mixer to prevent the mixture from splashing during the mixing process. However, when the mixer is in use, the blocked splashes will adhere to the protective plate. When the mixer is not in use, in order to prevent a large amount of concrete from falling on the protective plate, it is necessary to clean it up manually bit by bit, which is troublesome. Moreover, when the mixer is not in use, the mixing frame has no protective structure, which can easily damage the mixing frame, thereby affecting the use of the mixer. Utility Model Content

[0022] The upper surface of the arc-shaped protective plate 6 and near both sides are provided with limiting slide grooves 602, and the two side surfaces of the arc-shaped protective plate 6 and near the front end and the rear end are provided with positioning grooves 601. The cooperation between the limiting slider 702 and the limiting slide groove 602 can assist the arc-shaped flap 7 to rotate smoothly; the lower surface of the arc-shaped flap 7 and near both sides of the rear end are fixedly installed with limiting sliders 702, and the surface of the arc-shaped flap 7 and between the limiting sliders 702 are provided with a bayonet 701, and the two side surfaces of the arc-shaped flap 7 and near the rear end are provided with rod grooves 703; the scraping member 8 includes a scraping strip 801, a connecting rod 802, a positioning column 803, an insert rod 804, a stop block 805 and a spring 806. The lower surface of one end of the scraping strip 801 is fixedly installed with a connecting rod 802, and a positioning column 803 is fixedly installed on the surface of one side of the connecting rod 802 and near the top. An insertion rod 804 is fixedly installed on the surface and below the positioning column 803; the rear end of the insertion rod 804 is embedded in the rod groove 703, and a stop block 805 is fixedly installed on the rear end face of the insertion rod 804, and a spring 806 is sleeved on the surface of the insertion rod 804 located inside the rod groove 703; the positioning column 803 is embedded in the positioning groove 601, and the limiting slide block 702 is embedded in the limiting slide groove 602.
