Description

Technical Field

[0001] The present invention relates to the technical field of concrete mixers, and in particular to a concrete mixer for construction engineering. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities. At present, during the construction of construction projects, concrete mixers are required to assist in the construction.

[0003] After searching, according to the patent network CN107336348A, a concrete mixer for construction engineering is announced, whose structure includes a motor, a roller, a dosing device, an inclined bracket, a feed port, a pipe, a cylinder, a discharge port, a fuselage, an iron column, and a switch. The fuselage is a rectangular structure with a height of 55 cm, a length of 150 cm, and a width of 70 cm. The fuselage and the roller are movably connected by an interference fit. The roller is circular with a radius of 20 cm. There are two rollers with the same equilateral size. The fuselage and the dosing device are movably connected by an interference fit, and the dosing device is a rectangular structure with a height of 13 cm, a length of 23 cm, and a width of 13 cm. The invention discloses a concrete mixer for construction engineering, which is provided with a dosing device. When mixing concrete, the amount of cement, sand, stone, and water is adjusted by the regulator in the dosing device in conjunction with the display, and the amount is displayed on the display to prevent uneven mixing, thereby ensuring the firmness of the concrete.

[0004] However, although the existing concrete mixer can perform good mixing and processing operations on concrete when in use, when the concrete mixer is used daily, the auxiliary storage effect of the raw materials in the feeding pipe is not high, and the synchronous adjustment effect of the inner wall diameter in the feeding pipe is not good. At the same time, when the raw materials are added and conveyed through the feeding pipe, the mixing and conveying effect of the raw materials in the feeding pipe is not good, which easily causes the raw materials to be blocked in the feeding pipe and reduces the effect of the raw material adding rate. At the same time, when the concrete mixer is used daily, the use angle adjustability of the guide plate is not high. At the same time, the engagement, disassembly, and replacement effect of the guide plate is not high after long-term use, which easily causes the guide plate to form lumps on the surface of the guide plate after long-term use, affecting the concrete discharge amount, and does not meet people's use needs. For this reason, we propose a concrete mixer for construction engineering. Summary of the invention
