[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] Embodiment: A silo unloader that facilitates internal maintenance, see Figure 1-Figure 5 As shown, it includes a silo 1, a pressure reducing cone 2, a base 3, a maintenance channel 4, a partition 5, a feed pipe 6, a valve 7, a drive assembly 8, a reinforcing rib 9, a fixed pulley 10, a fixed plate 11, a wire rope 12, a rocker 13, a lifting assembly 14, an oil discharge pipe 15 and a scraper 16. The top of the base 3 is connected to the silo 1, and both sides of the silo 1 are connected with maintenance channels 4. The maintenance channels 4 are triangular in shape, and the maintenance channels 4 are convenient for people to repair. The maintenance channels 4 are connected with a pressure reducing cone 2, and the pressure reducing cone 2 is located inside the silo 1. The pressure reducing cone 2 is used to reduce the pressure generated by the material. A partition 5 is welded inside the base 3, and the base 3 is connected with a feed pipe 6. There is a certain gap between the feed pipe 6 and the partition 5. A valve 7 is installed on the feed pipe 6, and a drive assembly 8 is installed on the base 3. A reinforcing rib 9 is installed on the base 3, and the reinforcing rib 9 is connected to the drive assembly 8. Next, a fixed pulley 10 is installed on the upper inner part of the decompression cone 2, and two fixed pulleys 10 are also installed on the left part of the decompression cone 2. The two fixed pulleys 10 on the left are vertically arranged, and a fixed plate 11 is connected to the upper inner part of the decompression cone 2, and the fixed plate 11 is located below the fixed pulley 10 on the upper side. A wire rope 12 is wound around the fixed pulley 10 on the far left, and the wire rope 12 is wound around the other two fixed pulleys 10. The winding method of the wire rope 12 is from bottom to top, and a rocker 13 is connected to one side of the fixed pulley 10 on the far left, and the rocker 13 is L-shaped. A hoisting assembly 14 is connected to the right end of the wire rope 12, and the hoisting assembly 14 is located above the driving assembly 8. An oil drain pipe 15 is connected to one side of the driving assembly 8, and the oil drain pipe 15 passes through the decompression cone 2 and the silo 1. A scraper 16 is connected to the output shaft of the driving assembly 8 through a coupling, and the scraper 16 is located above the partition 5, and the scraper 16 is spirally arranged.

[0027] When the device is needed, people first place the device at the designated position, and then pour the material to be stored into the silo 1. The pressure reducing cone 2 can reduce the pressure generated by the material. When unloading is needed, people open the valve 7 and start the driving assembly 8, so that the material in the silo 1 falls down through the feed pipe 6 to the gap between the partition 5 and the base 3. At the same time, the output shaft rotation of the driving assembly 8 can drive the scraper 16 to rotate, and the rotation of the scraper 16 can scrape the material falling in the gap between the partition 5 and the base 3, so that the material falls down through the partition 5 and is discharged, thereby achieving the purpose of unloading. After the unloading is completed, the valve 7 and the driving assembly 8 are closed, and then the driving assembly 8 is turned on. The oil generated when the component 8 is running is discharged outward through the oil drain pipe 15. When the drive component 8 needs to be repaired, first reach into the maintenance channel 4 to hang the lifting component 14 on the drive component 8, and then turn the rocker 13. The rotation of the rocker 13 drives the fixed pulley 10 to rotate. The rotation of the fixed pulley 10 can pull the lifting component 14 upward through the wire rope 12, which can drive the drive component 8 to move upward. At this time, people can repair the drive component 8 through the maintenance channel 4. After the repair, reverse the rocker 13 to drive the lifting component 14 and the drive component 8 to move downward and reset, and reinstall the drive component 8, and then remove the drive component 8 from the lifting component 14.
