Abstract

This utility model discloses a concrete block sand proportioning device, including a mixing tank. The mixing tank is equipped with a sand proportioning and mixing structure. This utility model relates to the field of concrete block batching and proportioning technology. Based on the batching and mixing, this utility model adds a metering device at the inlet of the feed hopper to control the amount of feed. At the same time, the mixing process is divided into two parts: preliminary mixing and then water spraying and mixing. This solves the problems that are easy to waste sand materials due to improper sand proportioning during the mixing process, and uneven mixing of concrete materials due to adding water at one time. This reduces work efficiency and increases production costs.
