[0002] A cement silo is a container for storing cement. It is made of welded steel plates and is commonly used in places such as concrete mixing plants and cement plants. Cement silos are usually cylindrical in structure, with a conical discharge port at the bottom and a feed port at the top. They can store large amounts of cement and provide a stable supply of cement. However, cement is sticky and will remain on the inner wall of the cement silo when it is discharged. The residual cement will clump and corrode the inner wall of the cement silo and affect the capacity of the cement silo. In order to address the shortcomings of the existing technology, we proposed a cement silo with a scraper structure. Utility Model Content

[0012] The utility model uses a scraper assembly, including a scraper, to control the cylinder to extend the push rod, drive the motor, the connecting rod and the scraper to move downward until they reach the inner cavity of the silo, and then the motor drives the connecting rod and the scraper to rotate, so as to scrape the material on the inner cavity surface of the silo. After scraping, the cylinder drives the motor and the connecting rod to rise. When the connecting rod approaches the rectangular box, the cylindrical tube one gradually approaches the cylindrical tube two. Under the action of the cylindrical tube two, the connecting rod is pushed to rotate until it is parallel to the length direction of the rectangular box. After scraping, the pin can be pulled out from the lock buckle, and the door panel is opened to clean the scraper. With the above structure, the scraper is driven to rise and fall by the cylinder, and the scraper is driven to rotate by the motor, so that the cement remaining on the inner wall of the cement silo can be scraped off. The scraper is stored in the rectangular box, which can avoid the scraper being soaked in cement when storing cement, and also avoids cement sticking to the inner wall of the cement silo, thereby reducing the corrosion of the cement on the inner wall of the cement silo, and avoiding the agglomerated cement affecting the capacity of the cement silo, thereby improving the flexibility of the device.

[0013] The utility model replaces the components including the mounting plate. If the scraper needs to be replaced, the movable splint is moved away from the top of the mounting plate by toggling the movable splint, and the mounting plate can be taken out. Then the new mounting plate is placed on the top of the two elastic clamping blocks and positioned by the two locating pins and the two locating holes. At this time, the movable splint is released, and under the thrust of the spring two, the movable splint will move to the top of the mounting plate and cooperate with the two elastic clamping blocks to clamp the mounting plate. With the above structure, the scraper and the mounting plate can be disassembled and installed by toggling the movable splint, which is convenient for the user to clean or replace the scraper, avoids the cement lumps remaining on the scraper surface from scratching the inner wall of the cement silo, and improves the practicality of the device.

[0023] The central axes of the hollow tube 41, cylinder 42, motor 43, cylindrical tube 1 46, and cylindrical tube 2 49 coincide with the central axis of the silo body 1. The scraper 45 is in contact with the inner surface of the silo body 1. The guide rod 1 48 is used to limit the movement direction of cylindrical tube 2 49 to be parallel to the length direction of the cylinder 42. The adjacent ends of cylindrical tube 1 46 and cylindrical tube 2 49 are both inclined end surfaces, and the inclination angles of the inclined end surfaces of cylindrical tube 1 46 and guide rod 1 48 are equal.

[0024] The cylinder 42 can drive the motor 43, the connecting rod 44 and the scraper 45 to move up and down. When the connecting rod 44 moves upward, the force of the cylindrical tube 2 49 on the cylindrical tube 1 46 will push the connecting rod 44 to rotate, thereby driving the length direction of the connecting rod 44 to be parallel to the length direction of the rectangular box 412, so that the connecting rod 44 can be retracted into the inner cavity of the rectangular box 412.

[0025] The top surface of the rectangular box 412 is provided with a take-in / take-out opening, and the bottom surface of the door panel 413 is fixedly connected with a sealing gasket, which is located directly above the take-in / take-out opening.

[0029] The scraper 45 can be installed on one end of the connecting rod 44 by placing the mounting plate 51 on top of the two elastic clamping blocks 53 and positioning it through two positioning pins 54 and two positioning holes 55, and then clamping the top surface of the mounting plate 51 with the movable clamping plate 59.

[0030] The top surface and the bottom surface of the mounting plate 51 are respectively fitted with the movable clamping plate 59 and the two elastic clamping blocks 53 .

[0031] The working process of this utility model is as follows:

[0032] First, the cylinder 42 is controlled to extend the push rod, driving the motor 43, the connecting rod 44 and the scraper 45 to move downward until they reach the inner cavity of the warehouse body 1. Then the motor 43 drives the connecting rod 44 and the scraper 45 to rotate, thereby scraping the inner cavity surface of the warehouse body 1. After the scraping is completed, the cylinder 42 drives the motor 43 and the connecting rod 44 to rise. When the connecting rod 44 approaches the rectangular box 412, the cylindrical tube 1 46 gradually approaches the cylindrical tube 2 49. Under the force of the cylindrical tube 2 49, the connecting rod 44 is pushed to rotate until it is parallel to the length direction of the rectangular box 412. After scraping, Pull out the latch 415 from the lock 414 and open the door panel 413 to clean the scraper 45. If the scraper 45 needs to be replaced, move the movable splint 59 away from the top of the mounting plate 51 to remove the mounting plate 51. Then place the new mounting plate 51 on top of the two elastic clamping blocks 53 and position it with the two locating pins 54 and two locating holes 55. At this time, release the movable splint 59. Under the thrust of spring 2 58, the movable splint 59 will move to the top of the mounting plate 51 and cooperate with the two elastic clamping blocks 53 to clamp the mounting plate 51.
