Description

Technical Field

[0001] This utility model relates to the field of concrete pre-storage silos, specifically to a pre-storage silo for anti-solidification commercial concrete. Background Technology

[0002] Anti-curing ready-mixed concrete pre-storage silos are facilities specifically designed for the temporary storage of ready-mixed concrete. Their main function is to effectively prevent concrete from curing due to static storage during the pre-storage period. By continuously stirring, they maintain the uniformity and fluidity of the concrete, precisely control the temperature to avoid accelerated curing caused by thermal expansion and contraction or unsuitable temperatures, and add admixtures as needed to optimize concrete performance. This ensures that the concrete is always in a good, usable condition during the pre-storage stage, greatly improving the flexibility and efficiency of ready-mixed concrete production and use, reducing material waste, and ensuring the continuity of construction projects.

[0003] Chinese patent provides an information-controlled pre-storage silo for commercial concrete, publication number CN217228699U. It includes a pre-storage silo with a feed pipe at the top and a support column at the bottom. An anti-solidification mechanism is installed inside the silo, comprising a rotating rod with a fixed shell on the outer side of its top. A motor is mounted on the top of the inner wall of the fixed shell, a rotating rod is mounted on the outer side of the rotating rod, and a fixed rod is mounted at the bottom of the rotating rod. This invention, by incorporating an anti-solidification mechanism, scrapes the inner wall of the pre-storage silo to prevent the concrete from solidifying. It also prevents concrete from adhering to the inner wall during discharge, thus reducing concrete waste and avoiding the space occupied by solidified concrete. Furthermore, double mixing prevents concrete from solidifying.

[0004] The aforementioned pre-storage silo has the effect of avoiding residual concrete inside the silo and preventing concrete from solidifying. However, when concrete is loaded into the silo, some concrete will remain on the inner wall of the feed pipe, which will also cause concrete waste. Therefore, it is necessary to provide a pre-storage silo for anti-solidification commercial concrete. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-storage silo for anti-solidification commercial concrete to solve the problem of concrete residue remaining on the inner wall of the inlet of existing storage silos during concrete filling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-storage silo for anti-solidification commercial concrete, comprising a silo body and a feed pipe, the feed pipe being located on one side of the top of the silo body, a stirring roller being installed inside the silo body, a fixed frame being installed on the top of the silo body, two sets of threaded rods and a fixed plate being installed inside the fixed frame, the fixed plate and the threaded rods being threadedly connected, the threaded rods being rotatably connected to the fixed frame, two sets of gears and a rack being installed inside the fixed frame, both sets of gears being meshed with the rack, both sets of gears being rotatably connected to the fixed frame, and both sets of gears being fixedly connected to the two sets of threaded rods respectively, and three sets of uprights being installed at the bottom of the fixed plate, with scrapers fixedly connected to the ends of the uprights.

[0007] Preferably, the fixing frame is fixedly connected to the top of the hopper, and the fixing frame is located outside the feed pipe.

[0008] Preferably, the scraper is located directly above the feed pipe, and the scraper is adapted to the size of the feed pipe.

[0009] Preferably, a motor is provided at the end of one of the threaded rods, the output shaft of the motor is fixedly connected to the threaded rods, and the motor is fixedly connected to the top of the silo.

[0010] Preferably, the bottom of the silo is provided with a discharge port, which is located at the center of the bottom of the silo, and a valve is provided at the discharge port.

[0011] Preferably, a second motor is provided at the bottom of the fixed plate, and a second threaded rod is fixedly connected to the output shaft of the second motor. The second threaded rod is rotatably connected to the scraper.

[0012] Preferably, the threaded rod is externally threaded to a connecting sleeve, and the connecting sleeve is movably connected to six sets of connecting rods. The connecting rods are movably connected to a support plate, and a slider is provided at the bottom of the support plate. A groove is provided through the top of the scraper, and the slider is located in the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This pre-storage silo for anti-solidification commercial concrete is equipped with two sets of threaded rods, a motor, and a vertical pole in conjunction with a scraper. The scraper can move upward and downward. When the scraper moves upward, the inlet of the feed pipe is opened to facilitate the filling of concrete. When the scraper moves downward, it can scrape off the concrete remaining on the inner wall of the feed pipe and make it fall into the silo. When the scraper moves to the end of the feed pipe, it can also seal the inlet of the feed pipe, thus facilitating the preservation of concrete.

[0015] 2) This anti-solidification pre-storage silo for commercial concrete, through the setting of threaded rod II, motor II, connecting sleeve, connecting rod, slider, and groove in conjunction with the support plate, can make the overall components of the scraper more stable. When the scraper moves to the end of the feed pipe, motor II is started, threaded rod II rotates and drives the connecting sleeve to move downward, and the connecting rod pushes the support plate to expand outward, so that the support plate can be supported inside the feed pipe, making the components above the scraper more stable.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figure 1 - Figure 6 A pre-storage silo for anti-solidification commercial concrete includes a silo body 1 and a feed pipe 2. The feed pipe 2 is located on one side of the top of the silo body 1, and a mixing roller is installed inside the silo body 1.

[0026] See Figure 1, Figure 2 , Figure 3 , Figure 5 Furthermore, it is found that a fixed frame 4 is provided on the top of the silo body 1, and two sets of threaded rods 5 and a fixed plate 7 are provided on the inner side of the fixed frame 4. The fixed plate 7 and the threaded rods 5 are threadedly connected, and the threaded rods 5 are rotatably connected to the fixed frame 4. Two sets of gears 17 and one set of racks 18 are provided inside the fixed frame 4. Both sets of gears 17 are meshed with the racks 18. Both sets of gears 17 are rotatably connected to the fixed frame 4. The two sets of gears 17 are fixedly connected to the two sets of threaded rods 5 respectively. Three sets of uprights 8 are provided at the bottom of the fixed plate 7, and scrapers 9 are fixedly connected to the ends of the uprights 8.

[0027] Specifically, scraper 9 is positioned directly above feed pipe 2. When scraper 9 moves upward, it facilitates material pouring. When scraper 9 moves downward, it removes concrete residue remaining on the inner wall of feed pipe 2 during pouring, allowing the concrete to fall into the silo 1, thus reducing concrete waste. In addition, when scraper 9 moves into the inside of feed pipe 2, it can also seal the opening of feed pipe 2, facilitating concrete preservation.

[0028] Example 2

[0029] See Figure 4 and Figure 6 Furthermore, based on Embodiment 1, the following is further obtained: the fixing frame 4 is fixedly connected to the top of the silo 1, and the fixing frame 4 is located outside the feed pipe 2; the scraper 9 is located directly above the feed pipe 2, and the scraper 9 is adapted to the size of the feed pipe 2; a set of threaded rods 5 is provided with a motor 6 at its end, the output shaft of the motor 6 is fixedly connected to the set of threaded rods 5, and the motor 6 is fixedly connected to the top of the silo 1; the bottom of the silo 1 is provided with a discharge port 3, the discharge port 3 is located at the center of the bottom of the silo 1, and a valve is provided at the discharge port 3; the bottom of the fixing plate 7 is provided with a motor 10, the output shaft of the motor 10 is fixedly connected to a threaded rod 11, and the threaded rod 11 is rotatably connected to the scraper 9; the threaded rod 11 is externally threadedly connected to a connecting sleeve 12, the connecting sleeve 12 is externally movably connected to six sets of connecting rods 13, the connecting rods 13 are movably connected to a support plate 14, the bottom of the support plate 14 is provided with a slider 15, a groove 16 is opened through the top of the scraper 9, and the slider 15 is located in the groove 16.

[0030] Specifically, when the scraper 9 moves to the inside of the feed pipe 2, the motor 10 is started, and the threaded rod 11 rotates, causing the connecting sleeve 12 to move downward. The downward movement of the connecting sleeve 12 causes the connecting rod 13 to push the support plate 14 to expand outward. When the support plate 14 expands outward, the slider 15 at its bottom slides in the groove 16. When the connecting sleeve 12 moves to the bottom of the threaded rod 11, the support plate 14 is externally supported on the inside of the feed pipe 2, thereby supporting the scraper 9 and the components above it, making the whole structure more stable.

[0031] In actual operation, motor 6 is started, and a set of threaded rods 5 rotates. The rotation of threaded rods 5 drives a set of gears 17 to rotate, which in turn drives a rack 18 to rotate. The rack 18 then drives another set of gears 17 to rotate, allowing both sets of threaded rods 5 to rotate simultaneously. The rotation of threaded rods 5 causes the fixed plate 7 to move upward, finally causing the scraper 9 to disengage from the feed pipe 2, allowing concrete to be poured. After pouring, motor 6 is started again, causing the scraper 9 to move downward. As the scraper 9 moves downward, it scrapes the residual concrete on the inner wall of the feed pipe 2 into the silo 1, thus avoiding concrete waste. After scraping, the scraper 9 also acts as a seal for the feed pipe 2, thus better preserving the concrete. When the scraper 9 moves to the end of the feed pipe 2, motor 10 is started, and threaded rod 11 rotates, causing the connecting sleeve 12 to move downward. The downward movement of the connecting sleeve 12 causes the connecting rod 13 to push the support plate 14 to expand, thereby allowing the support plate 14 to support the scraper 9 and the components above it, making the whole structure more stable.

[0032] 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 the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
