Description

technical field [0001] The invention relates to an engineering construction machine, in particular to a concrete preparation machine suitable for water conservancy construction. Background technique [0002] Concrete is the most important building material, and engineering designers need to choose different concrete ratio designs according to the project structure, the amount of steel reinforcement, construction methods and other requirements. The so-called concrete construction mix ratio refers to the proportional relationship between the various constituent materials in concrete. The constituent materials include cementitious materials, cement, sand, stones and water. In the prior art, the sand and stones that are sieved out are inaccurately weighed when they are prepared on site, and the design of concrete mix ratio is a very important task in concrete engineering, which directly affects the smooth construction of concrete and the quality of concrete engineering. and the...

Problems solved by technology

In the prior art, the sand and stones that are sieved out are inaccurately weighed when they are prepared on site, and the design of concrete mix ratio is a very important task in concrete engineering, which directly affects the smooth construction of concrete and the quality of concrete engineering. and the cost of concrete works

There is an error between the actual configuration of concrete and the preset concrete mix ratio, which is a common problem in existing engineering construction. For projects with relatively high requirements, only raw materials that have been weighed and packaged can be purchased, resulting in high construction costs

[0003] In order to reduce costs, there are currently projects that adopt on-site weighing and weighing for concrete configuration. Usually, it is conveyed through the material belt and transported to a small material pan for weighing. However, when the sand and gravel materials fall to the material pan, it will cause a downward impact on the material pan. , and the impact force of materials with different densities is also different, which will interfere with the weighing process

[0004] In addition, the specifications of bulk sand and gravel are not uniform. During the configuration process, it is first necessary to sieve sand of different thicknesses according to the preset ratio, so as to be used for different purposes.

As a result, the existing configuration method is complicated to operate and consumes a lot of manpower
