[0002] Concrete is an artificial stone made by mixing cement, sand, aggregates (such as crushed stones and crushed bricks) and water in a certain proportion, and is mainly used in building structures. Concrete is a common material in the construction field and plays an important role in construction projects. Before mass production of existing concrete, the concrete composition needs to be adjusted through trial mixing operations. Currently, trial mixing operations are carried out on concrete to ensure that the quality of the concrete meets the requirements. When carrying out trial mixing operations, corresponding trial mixing devices are usually required. An existing trial mixing device, as disclosed in Chinese Patent CN201920894728.1, is a concrete production trial mixing and testing device, including a base. A surrounding plate is welded to the top of the base, and support rods are welded to the four corners of the top of the surrounding plate. The tops of the four groups of support rods are welded to the four corners of the bottom of the mounting plate. A motor is bolted to the middle of the top of the mounting plate. A micro control computer is screwed to the middle of the right side of the motor. A switch and a time display screen are fixedly installed on the right side of the micro control computer. A power cord is connected to the bottom of the micro control computer. Through the settings of the base, the surrounding plate and the stirring blades, the motor drives the stirring blades to rotate through the rotating shaft to stir the concrete, and the trial mixing operation can be quickly completed, which is convenient for checking whether the ratio is appropriate. However, it is found in the use process that it is difficult to disassemble and clean each part of the device after use, and it is not convenient to repair and replace some damaged parts of the device, resulting in high maintenance costs.
