Background Art

Commercial concrete, also known as ready-mixed concrete, refers to a pre-mixed concrete mixture of qualified quality, which is sold to construction units in the form of commodities and transported to the construction site for pouring. Commercial concrete has strict control management from raw materials to product production, accurate measurement, and complete inspection methods, so that the quality of concrete is fully guaranteed, while reducing the pollution to the environment during the concrete production process. Concrete is an artificial stone made of cementitious materials, aggregates and water in a certain proportion, stirred and vibrated into shape, and cured under certain conditions. The aggregates are generally sand and stone, which play a skeleton role in concrete. The silo in the concrete mixing station is used to store sand and soil raw materials. At present, the storage silo for storing sand and gravel is mainly composed of a storage hopper, a discharge mechanism and a discharge port.

When the concrete silo is discharged in the prior art, the materials gather to the discharge port at the lower end of the storage silo under the action of gravity. When discharging, the materials are easy to adhere to the inner wall and cause blockage of the discharge port, affecting the continuity of the entire concrete preparation work, affecting the efficiency of the equipment and causing economic losses. In order to reduce or avoid the discharge blockage caused by the discharge of concrete raw materials, we propose a concrete silo.

Please refer to Figures 1-5. The utility model provides a technical solution: a concrete silo, including a silo body 1, a discharge pipe 2 is fixedly connected to the bottom of the silo body 1, a rotating tube 11 is rotatably penetrated at the top of the silo body 1, a lifting connection piece 19 is installed inside the rotating tube 11, a lifting sleeve 9 is fixedly connected to the bottom of the lifting connection piece 19, the lifting sleeve 9 is slidably sleeved on the bottom of the rotating tube 11, a spiral unloading blade 8 is installed on the outer surface of the lifting sleeve 9, a limiting sleeve 7 is fixedly connected to the inner wall of the rotating tube 11, the lifting connection piece 19 is slidably penetrated on the limiting sleeve 7, and a transmission rod 6 is rotatably connected to the top of the lifting connection piece 19, the top of the transmission rod 6 slides out of the top of the rotating tube 11, a driving component for driving the rotating tube 11 to rotate is installed at the top of the silo body 1, and a lifting component for driving the transmission rod 6 to lift and lower is installed at the top of the silo body 1.

When the concrete raw material is discharged, the driving component will drive the rotating tube 11 to rotate, and the rotating tube 11 will drive the limiting sleeve 7 to rotate when it rotates. Since the lifting connection 19 is slidably inserted into the limiting sleeve 7, the lifting connection 19 will be driven to rotate synchronously. When the lifting connection 19 rotates, the lifting sleeve 9 and the spiral feeding blade 8 will be driven to rotate. The spiral feeding blade 8 can assist in logistics feeding. When the driving component is working, the lifting component will drive the spiral feeding blade 8 to perform lifting and lowering motion at the same time. The spiral feeding blade 8 performs repeated up and down motions while rotating itself, thereby reducing or avoiding the blockage of materials in the bin body 1.

The driving assembly includes a motor 16, a mounting frame 18 is fixedly connected to the top of the warehouse body 1, the motor 16 is fixedly installed on the mounting frame 18, the output end of the motor 16 is fixedly connected to an output shaft, the outer surface of the output shaft is fixedly sleeved with a driving sprocket 12, the outer surface of the rotating tube 11 is fixedly sleeved with a driven bevel gear 15, a transmission shaft is rotatably installed on the mounting frame 18, one end of the transmission shaft is fixedly connected to a driving bevel gear 17, the driving bevel gear 17 is meshed with the driven bevel gear 15, the other end of the transmission shaft is fixedly connected to a driven sprocket 10, and a transmission chain 20 is connected between the driven sprocket 10 and the driving sprocket 12.

When the driving assembly is used, the motor 16 is started, and the motor 16 drives the active bevel gear 17 to rotate through the transmission chain 20. Since the active bevel gear 17 is meshed with the driven bevel gear 15, the rotating tube 11 is driven to rotate, thereby realizing the rotation of the spiral unloading blade 8.

The lifting assembly includes a turntable 5, which is fixedly connected to the end of the output shaft of the motor 16. The top of the transmission rod 6 is fixedly connected to a frame 14. A slider 13 is slidably mounted inside the frame 14. A matching shaft is rotatably mounted between the slider 13 and the turntable 5.

When the motor 16 is working, it will drive the turntable 5 to rotate at the same time. When the turntable 5 rotates, the slider 13 will make the frame 14 reciprocate up and down. Since the lifting connection 19 is slidably penetrated on the limit sleeve 7, the lifting sleeve 9 is slidably sleeved on the bottom of the rotating tube 11, and then the spiral feeding blade 8 will reciprocate up and down while rotating itself.

A plurality of scrapers 3 are fixedly connected to the outside of the rotating tube 11. The scrapers 3 are in contact with the inner wall of the bin body 1. When the rotating tube 11 rotates, the scrapers 3 are driven to rotate. When the scrapers 3 rotate, the raw materials on the inner wall of the bin body 1 can be scraped off, thereby reducing material waste.

A valve is installed on the discharge pipe 2, and a plurality of limit telescopic rods are connected between the frame 14 and the bin body 1. The limit telescopic rods can make the frame 14 move up and down stably.

Working principle: When the concrete raw material is discharged, the motor 16 is started, and the motor 16 will drive the active bevel gear 17 to rotate through the transmission chain 20. Since the active bevel gear 17 is meshed with the driven bevel gear 15, it will drive the rotating tube 11 to rotate. When the rotating tube 11 rotates, it will drive the limit sleeve 7 to rotate. Since the lifting connection 19 is slidably installed on the limit sleeve 7, it will drive the lifting connection 19 to rotate synchronously. When the lifting connection 19 rotates, it will drive the lifting sleeve 9 and the spiral unloading blade 8 to rotate. The spiral unloading blade 8 can assist the logistics to go down. When the motor 16 is working, it will drive the turntable 5 to rotate at the same time. When the turntable 5 rotates, the slider 13 will make the frame 14 reciprocate up and down. Since the lifting connection 19 is slidably penetrated on the limit sleeve 7, the lifting sleeve 9 is slidably sleeved on the bottom of the rotating tube 11, and then the spiral unloading blade 8 will reciprocate up and down while rotating itself, thereby reducing or avoiding the blockage of materials in the warehouse body 1; when the rotating tube 11 rotates, it will drive the scraper 3 to rotate, and when the scraper 3 rotates, it can scrape the raw materials on the inner wall of the warehouse body 1, thereby reducing the waste of materials.
