Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a mixing device for concrete production. Background Technique

[0002] Concrete refers to the general term of engineering composite materials that bind aggregates into a whole by cementitious materials. Usually, the term "concrete" refers to cement concrete, also known as ordinary concrete, which uses cement as the cementitious material, sand and stone as aggregates, and is mixed with water (which may contain additives and admixtures) in a certain proportion through stirring. It is widely used in civil engineering. During the production process of concrete, a mixing device for concrete production is required.

[0003] The Chinese patent with the authorization publication number CN221314660U discloses a concrete mixing device, including a cylinder body. A cylinder cover is arranged on the upper side of the cylinder body, and a fixing plate is fixed on the outer side of the cylinder body. A water tank is fixed on the upper side of the fixing plate, and a water pump is installed on the outer side of the water tank. The water pumping end of the water pump is communicated with the inside of the water tank; in the utility model, when the water pump is started, water flow is conveyed into the hollow rod through a hose and sprayed through a plurality of water outlet holes. The switch of the driving motor is turned on to drive the large gear to rotate. The large gear meshes with the small gear, and then the small gear rotates, and then the hollow rod rotates, and a plurality of stirring rods rotate to perform stirring. At the same time, the inner wall of the cylinder body can be scraped and swept by a plurality of brush hairs during stirring, avoiding the adhesion of raw materials to the inner wall, resulting in inconvenient subsequent cleaning; it solves the problem that the existing device cannot scrape and clean the inner wall during stirring, and caking occurs after long-term placement, which is not convenient for subsequent cleaning.

[0004] Although the above-mentioned concrete mixing device solves the problem that the existing device cannot scrape and clean the inner wall during stirring, and caking occurs after long-term placement, which is not convenient for subsequent cleaning, during the preparation process of concrete, it is usually necessary to put the required materials into the mixing device for stirring and mixing. When mixing, people need to continuously feed cement powder into the device, and a large amount of dust will be raised during the feeding process of cement powder, which endangers people's health. Moreover, during the stirring process of the existing concrete mixing device, it usually can only stir in one direction, resulting in low stirring efficiency. Therefore, we propose a mixing device for concrete production. Content of the Utility Model

[0027] Please refer to Figure 1 and 3 , A mixing device for concrete production, comprising: a storage tank 10, which is installed on one side above the outside of the mixing tank 1. Below the storage tank 10, there is a feeding pipe 11 connected.
