Description

Technical Field

[0001] The utility model relates to the technical field of vibration levelers, in particular to a concrete surface vibration leveler. Background Art

[0002] Concrete surface vibrating leveler is an important tool in the construction field, mainly used for leveling and compacting the concrete surface. Concrete surface vibrating leveler is a special equipment that level and compacts the concrete surface through vibration and compaction. It uses the principle of high-speed rotation or reciprocating vibration to generate a strong vibration force to disperse the particles in the wet concrete and discharge the bubbles in it, thereby enhancing the fluidity and density of the concrete.

[0003] After searching, the utility model with the announcement number CN204059988U discloses a concrete surface vibration leveler. Although the utility model patent ensures the leveling effect of the concrete surface through a vibration motor with an eccentric block, it will not affect the leveling effect of the leveling plate, ensuring that any part of the leveling plate can achieve a good leveling effect during the working process; it solves the problem that the gravity of the vibration motor is completely concentrated in the same position, resulting in a high pressure on this part; but

[0004] First, the utility model needs to be vibrated twice when used. The first time is mainly to make the concrete dense, and the second time is mainly to make the concrete surface flat, which prolongs the construction time, thereby reducing work efficiency and may cause equipment wear, thereby increasing construction costs. At the same time, excessive vibration may cause micro cracks inside the concrete, thereby affecting its long-term performance;

[0005] Second, the utility model lacks the function of cleaning the leveling plate. If the leveling plate is not cleaned in time after use, the concrete residue from the previous use may remain on it. When the leveling plate is used again to process concrete, the residue may be mixed with the new concrete, resulting in quality problems of the concrete.

[0006] Therefore, a concrete surface vibration leveler is proposed. Utility Model Content
