Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a concrete powder storage device with a pushing mechanism. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added in a certain proportion, which are uniformly stirred, compacted, and hardened. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc., where concrete is also an important material.

[0003] For example, the Chinese utility model patent with application number: 202320842605.X discloses an environmentally friendly concrete powder storage device, which belongs to the field of powder storage technology, including a tank body, a driving mechanism is installed on the top of the tank body, the driving mechanism includes a fixed frame, the fixed frame is fixedly installed on the top of the tank body, a motor is fixedly installed on the bottom of the fixed frame, the output end of the motor penetrates into the tank body, the rotating shaft is fixedly connected to the output end of the motor, a plurality of first support frames are fixedly installed on the side wall of the rotating shaft, the scraper is fixedly installed on the end of the first support frame, the scraper is tightly attached to the inner cavity of the tank body, the stirring rod is fixedly installed on the side wall of the rotating shaft, and a plurality of stirring rods are provided. The utility model is provided with a driving mechanism, and the power brought by the motor can drive the rotating shaft to rotate, thereby driving the scraper and the stirring rod to rotate together, which can not only prevent the concrete powder from being difficult to discharge from the discharge port due to agglomeration, but also can scrape the powder remaining on the inner wall of the tank body.

[0004] The device in the above patent can scrape the powder on the inner wall of the tank body by rotating the scraper when in use. However, after the scraper is used for a long time, it will constantly rub against the inner wall of the tank body and easily cause the scraper to wear, so that the scraper no longer abuts against the inner wall of the tank body. When it needs to be replaced, since the scraper is arranged inside the device, the device needs to be opened before the scraper can be disassembled and replaced, which is time-consuming and labor-intensive and inconvenient to replace the scraper.
