Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a concrete mixing and feeding device. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. It is one of the most important civil engineering materials in modern times. Concrete is an artificial stone material made by mixing cementing materials, granular aggregates, water, and, when necessary, admixtures and additives in a certain proportion, uniformly stirring, compacting, and curing.

[0003] Existing feeding devices often have fixed feeding ports, which can lead to material accumulation during feeding and thus affect mixing efficiency. To address this, we propose a concrete mixing feeding device. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a concrete mixing and feeding device, including a mixing tank 1, which is used to contain concrete and provides an installation environment for the mixing component 3. The feeding component 2 is used to transport the concrete and can perform concrete feeding operations. The feeding component 2 is located on the outside of the mixing tank 1. The mixing component 3 is used to mix the concrete, thereby avoiding the accumulation of concrete raw materials when they are fed. The mixing component 3 is located on the inside of the mixing tank 1.

[0025] like Figure 1-5 As shown in the embodiment of this application, the stirring assembly 3 includes a motor 202, which is located at the bottom center of the stirring tank 1. The output end of the motor 202 is connected to a fixed shaft 304, which extends through to the top of the stirring tank 1. A feed hopper 207 is provided on one side of the top of the stirring tank 1. An annular sleeve 303 is provided on the outer wall of the fixed shaft 304. Specifically, the motor 202 is used to provide power to the stirring assembly 3 and the feeding assembly 2. The motors 202 in this application are all connected to an external power supply and controlled by a control system. When the motor 202 is started, it drives the fixed shaft 304 to rotate. The annular sleeve 303 is fixedly provided on the outer wall of the fixed shaft 304. Therefore, when the fixed shaft 304 rotates, it drives the annular sleeve 303 to rotate. When the annular sleeve 303 rotates, it drives the stirring paddle 301 to rotate. The fixed shaft 304 is rotatably located inside the stirring tank 1.

[0026] like Figure 1-5As shown in the embodiments of this application, the outer wall of the annular sleeve 303 is provided with multiple stirring paddles 301, a scraper 302 is provided on one side of the top of the stirring paddle 301, multiple fixing rods 306 are provided on the inner side of the stirring paddle 301, a hollow column 305 is provided on the outer wall of the fixing rod 306, a protrusion 102 is provided on the outer wall of the annular sleeve 303, the protrusion 102 is located at the top of the stirring paddle 301, a discharge pipe 101 is provided on one side of the bottom of the mixing tank 1, a protrusion 102 is provided on the bottom of the inner wall of the mixing tank 1, and a fixing shaft 304 is provided on the inner side of the protrusion 102. Specifically, under the cooperative action of the stirring paddles 301, the concrete can be broken up and the inner wall of the mixing tank 1 can be cleaned, thereby achieving... To prevent concrete residue from remaining on the inner wall of the mixing tank 1, both the mixing paddle 301 and the scraper 302 are in contact with the inner wall of the mixing tank 1. This allows the rotating mixing paddle 301 to scrape away any concrete adhering to the inner wall of the mixing tank 1. The scraper 302 is fixedly mounted on the top of the mixing paddle 301. A protrusion 102 on the top of the mixing paddle 301 is used for distributing the concrete. After the concrete falls into the mixing tank 1 through the feed hopper 207, some of the concrete will fall onto the protrusion 102. The rotation of the protrusion 102, driven by the annular sleeve 303, disperses the concrete into the mixing tank 1, thus preventing all the concrete from spilling out of the feed hopper 207. The concrete is poured onto one side of the mixing tank 1, thus preventing concrete accumulation. The protrusion 102 at the bottom of the inner wall of the mixing tank 1 disperses the concrete within the space between the protrusion 102 and the inner wall of the mixing tank 1 when it falls onto it. Then, under the rotation of the mixing paddle 301, the concrete is discharged from the discharge pipe 101. The discharge pipe 101 extends into the inner side of the mixing tank 1, and its concave shape facilitates smooth discharge of the concrete when it is brought to this position. The mixing paddle 301 contacts the protrusion 102 at the bottom of the inner wall of the mixing tank 1, thus scraping away the concrete on the protrusion 102. The mixing paddle 301 and the protrusion 102 are at the same height. The solid part is used to propel the concrete within the mixing tank 1. The part of the mixing paddle 301 above the protrusion 102 is provided with hollow columns 305. The hollow columns 305 are spaced apart to allow a large amount of concrete to circulate inside the mixing tank 1 when the mixing paddle 301 rotates, rather than just moving within the area between the mixing paddles 301 without interconnection. When the concrete passes through the hollow columns 305, there is a certain opportunity to drive the hollow columns 305 to rotate around the fixed rod 306. While the hollow columns 305 are rotating, they can break up and separate some of the lumpy concrete, dispersing it into small pieces so that it can be discharged from the discharge pipe 101 without causing blockage.

[0027] like Figure 1-5As shown in the embodiment of this application, the feeding assembly 2 includes a conveying cylinder 201, which rests against the feeding hopper 207. A motor 202 is installed at one end of the conveying cylinder 201, and an auger 203 is connected to the output end of the motor 202. A load-bearing plate 204 is installed on the outer wall of the conveying cylinder 201, and a fixing column 208 is installed on one side of the load-bearing plate 204. An inlet 205 and an outlet 206 are respectively installed on the outer wall near both ends of the conveying cylinder 201. The outlet 206 is directly opposite the inlet end of the feeding hopper 207. Specifically, the auger 203 can convey concrete. When the motor 202 is started, it drives the auger 203 to rotate. Workers pour concrete into the auger 203 through the inlet 205. Under the action of the conveyor, the concrete is conveyed to the area of ​​the discharge port 206. After being conveyed, the concrete is discharged from the discharge port 206 and enters the feed hopper 207 and then enters the mixing tank 1. The inner surface of the feed hopper 207 is smooth to facilitate the conveying of concrete. The load-bearing plate 204 is fixedly installed on the outer wall of the conveying cylinder 201. The load-bearing plate 204 is used to support the conveying cylinder 201. The top of the side of the feed hopper 207 facing the conveying cylinder 201 is provided with a groove that matches the conveying cylinder 201 to accommodate the conveying cylinder 201. The fixing column 208 is set separately to provide auxiliary support for the conveying cylinder 201. The position of the fixing column 208 is adjusted according to the height of the feed hopper 207.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
