Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete processing, in particular to a stirring device for high-durability recycled coarse aggregate concrete. Background Art
[0002] Concrete is a composite material formed by bonding fine aggregate and coarse aggregate with cement and hardening after a period of time. At present, recycled coarse aggregate prepared by recycling construction solid waste is generally added to concrete and mixed with ordinary coarse aggregate. Mixing equipment is needed to mix the concrete during the preparation process.
[0003] When using traditional concrete mixing equipment, one raw material is usually added from the feed port at one time and then another raw material is added. This causes the materials to pile up together after entering the mixing drum, thereby increasing the difficulty of mixing and resulting in a longer mixing time. In addition, the concrete inside the concrete mixing tank needs to be cleaned after use. If it is not cleaned, the concrete will condense inside the mixing tank, affecting the normal use of the mixing tank. Utility Model Content

[0022] By means of the swinging disc 8 and the swinging plate 9 arranged on the outer wall of the stirring rod 6, when aggregate and crushed stone are added into the inner cavity of the mixing tank 2 through the lower hopper 7, the stirring rod 6 rotates, which drives the swinging disc 8 to rotate, so that the swinging disc 8 can swing the falling crushed stone to all sides during the rotation, and evenly throw the crushed stone and aggregate into the inner cavity of the mixing tank 2, so that the crushed stone can be more fully mixed with sand and aggregate to form concrete.
[0023] In a preferred embodiment, the inner wall of the driving belt 5 at one end away from the driving motor 4 is rollingly connected to the outer wall of the stirring rod 6, and the driving belt 5 is made of vulcanized rubber.
[0024] By means of a driving belt 5 that is connected in a rolling manner on the power output shaft of the driving motor 4, the power of the driving motor 4 can be transmitted to the stirring rod 6 under the action of the driving belt 5, so that the stirring rod 6 rotates at a high speed under the action of the driving motor 4 and the driving belt 5, thereby stirring and mixing the materials in the inner cavity of the stirring tank 2 during the rotation of the stirring rod 6.
[0025] In a preferred embodiment, there are two lower material bins 7 , and the two lower material bins 7 are respectively installed on both sides of the outer wall of the top cover 3 .
[0026] By means of two lower material bins 7 arranged on the outer wall of the top cover 3, materials can be added into the inner cavity of the mixing tank 2 through the lower material bins 7, so that the materials can fall from the inner cavity of the top cover 3 to the top of the high-speed rotating swing plate 8, so that the materials are evenly added to the inner cavity of the mixing tank 2 under the drive of the swing plate 8 to rotate.
[0027] In a preferred embodiment, the inner wall of the threaded ring 14 is provided with an internal thread, and the inner wall of the threaded ring 14 is threadedly connected to the outer wall of the screw rod 13 .
[0028] By setting a threaded ring 14 in the inner cavity of the movable cylinder 11, and threadedly connecting the inner wall of the threaded ring 14 to the inner wall of the screw 13, when the scraper 15 is needed to scrape and clean the inner wall of the mixing tank 2, it is only necessary to drive the driving motor 12 to drive the screw 13 to rotate under the action of the screw 13, thereby driving the movable cylinder 11 to move forward along the inner wall of the fixed cylinder 10 during the rotation of the screw 13, and making the scraper 15 contact the inner wall of the mixing tank 2 in the process.
[0029] In a preferred embodiment, a controller is disposed on the top of the stirring tank 2 , and the controller is electrically connected to a driving motor 12 disposed in the inner cavity of the fixed cylinder 10 .
[0030] By means of a driving motor 12 arranged in the inner cavity of the fixed cylinder 10, the mobile cylinder 11 is moved in the inner cavity of the fixed cylinder 10 under the action of the driving motor 12. When the material needs to be stirred, the outer wall of the scraper 15 does not contact the inner wall of the mixing tank 2 under the action of the driving motor 12. When the equipment needs to be cleaned, the mobile cylinder 11 is driven to move outward along the inner wall of the fixed cylinder 10 by the rotation of the screw 13.
[0031] In a preferred embodiment, the swinging plate 9 is in an arc shape and is made of high carbon steel.
[0032] By setting the swing plate 9 on the top of the swing plate 8, the swing plate 8 drives the swing plate 9 to rotate during the rotation of the swing plate 8, so that during the rotation of the swing plate 9, the swing plate 9 that falls onto the outer wall of the swing plate 8 can be spread around, so that the material can evenly enter the inner cavity of the mixing tank 2.
[0033] Working principle: during the use of the above-mentioned equipment, the driving motor 4 is started, so that the driving motor 4 drives the stirring rod 6 to rotate through the driving belt 5, thereby driving the swing plate 8 to rotate during the rotation of the stirring rod 6. At this time, the material can be added to the inner cavity of the stirring tank 2 through the lower material bin 7 installed on the top of the top cover 3. When the material falls from the lower material bin 7 to the top of the swing plate 8, under the action of the swing plate 8, the material contacts the swing plate 9 on the outer wall of the swing plate 8, and is spread outward under the action of centrifugal force, so that the material can be evenly mixed from the inner wall of the stirring tank 2. The stirring rod 6 then moves downward, and then during the rotation of the stirring rod 6, the material is stirred under the action of the fixed cylinder 10, the mobile cylinder 11 and the scraper 15, so that the material is stirred more fully, and when the inner wall of the stirring tank 2 needs to be cleaned, the driving motor 12 is started by the controller, so that the driving motor 12 drives the screw 13 to rotate, so that during the rotation of the screw 13, the mobile cylinder 11 moves along the inner wall of the fixed cylinder 10 under the action of the screw 13, so that the outer wall of the scraper 15 contacts the inner wall of the stirring tank 2, and the inner wall of the stirring tank 2 is scraped and cleaned.
