Description

Technical Field

[0001] The utility model belongs to the technical field of concrete mixing, and in particular relates to an electronic batching scale. Background Art

[0002] Concrete is the main material of modern construction. Due to its strong plasticity and high strength, most buildings are poured with concrete. In order to ensure the quality of concrete, an electronic scale is needed to weigh the weight of the concrete ingredients during mixing so that the proportion meets the mixing requirements.

[0003] During the process of implementing this application, the inventors discovered that there are at least the following problems in this technology: when using existing electronic scales for concrete mixing, people need to manually take out the weighed ingredients, which is not only time-consuming and labor-intensive, but also difficult to clean the ingredients inside the electronic scale, greatly affecting the weighing accuracy of subsequent ingredients, resulting in inaccurate concrete mix ratios and affecting the quality of subsequent concrete mixing;

[0004] To solve the above problems, Chinese patent publication number CN217169107U discloses an electronic batching scale for concrete mixing. This prior art uses a weighing plate in a weighing cylinder for weighing and measuring. However, when workers add materials, they are prone to adding too much material, and then need to take the material out from the feed port, which is extremely inconvenient to use.
