The hot water or steam produced in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. A boiler that produces steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power plants, thermal power stations, ships, locomotives and industrial and mining enterprises.

The box 102 is used to store coal, and a discharge port 103 is provided at the side end of the storage box 102. The discharge port 103 is convenient for discharging coal. A pushing mechanism is provided at the side end of the storage box 102 for pushing the coal to be discharged, and a blocking mechanism is provided at the side end of the discharge port 103 for intercepting materials. A conveying mechanism for conveying coal is installed at the inner side end of the box body 1. After the coal is discharged to the top of the ramp plate 101 and approaches the conveying mechanism, the conveying mechanism can automatically convey the coal to the feed port 501, thereby realizing the feeding and adding of coal to the boiler 5. The coal can be automatically added into the boiler 5 without manual addition, which improves the efficiency of coal feeding and adding, saves time and effort, and personnel do not need to approach the boiler 5 to avoid burns.

[0021] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the blocking mechanism includes a plurality of baffles 104, which are fixedly connected to the top of the box body 1 near the discharge port 103, and a baffle plate 2 is inserted between the side ends of two adjacent baffles 104, and a handle 201 is fixedly connected to the side end of the baffle plate 2, and a limit plate 202 is fixedly connected to the top of the baffle plate 2. During implementation, the discharge port 103 can be opened by holding the handle 201 and pulling the limit plate 202. At this time, the coal can be easily discharged to the top of the ramp plate 101. When the coal in the storage box 102 does not need to be discharged anymore, the baffle plate 2 can be installed between the two baffles 104 by pushing the handle 201, thereby blocking the discharge port 103 to prevent coal from leaking out.

[0022] Furthermore, the pushing mechanism includes an electric push rod 4, which is fixedly installed on the side end of the storage box 102. A push plate 401 is fixedly installed on the side end of the electric push rod 4. The push plate 401 is located at the inner bottom end of the storage box 102. During implementation, the electric push rod 4 is started to drive the push plate 401 to push, so that the coal at the bottom can be pushed into the ramp plate 101, thereby avoiding material waste and eliminating manual cleaning of the bottom coal.

[0023] As an implementation method in this embodiment, Figure 1 As shown, the conveying mechanism includes a conveyor belt 3, which is fixedly installed on the inner side end of the box body 1, and a plurality of receiving boxes 301 are fixedly connected to the side end of the conveyor belt 3, and a vertical plate 302 is fixedly connected to the side end of the conveyor belt 3, and a discharge box 303 is fixedly connected to the bottom end of the vertical plate 302, and a discharge port 304 is provided at the bottom end of the discharge box 303, and a vibration motor 305 is fixedly installed at the bottom end of the discharge box 303. In practice, due to the setting of the ramp plate 101, the coal is accumulated at a position close to the conveyor belt 3. At this time, after the conveyor belt 3 is started, the conveyor belt 3 rotates the receiving box 301 at its side end to sequentially transfer the coal After digging into the receiving box 301, the conveyor belt 3 is rotated to transfer the coal to the position of the discharge box 303. The coal can fall into the discharge box 303 and be discharged into the feed port 501 through the discharge port 304, thereby feeding and adding coal to the boiler 5. The vibration motor 305 can assist the coal in the discharge box 303 that has not been successfully discharged to generate vibration and discharge it toward the discharge port 304. Therefore, the device can automatically add the coal into the boiler 5 without manual addition, thereby improving the efficiency of coal feeding and adding, saving time and effort, and at the same time, personnel do not need to approach the boiler 5 to avoid burns.

[0024] Working principle: Coal is put into the storage box 102 through the loading and unloading vehicle. At this time, the limit plate 202 is pulled out by holding the handle 201, and the discharge port 103 can be opened. At this time, the coal can be discharged to the top of the ramp plate 101. At this time, due to the setting of the ramp plate 101, the coal is accumulated at a position close to the conveyor belt 3. After the conveyor belt 3 is started, the conveyor belt 3 rotates and the receiving box 301 at its side end can dig the coal into the receiving box 301 in turn. At this time, the conveyor belt 3 is rotated to transfer the coal to the position of the discharge box 303, and the coal can fall into the discharge box 303 and discharge through the discharge port 304. The material is fed into the feed port 501, thereby realizing the feeding and adding of coal to the boiler 5. The vibration motor 305 can assist the coal in the discharge box 303 that has not been successfully discharged to generate vibration and discharge the material toward the discharge port 304. Therefore, the device can automatically add the coal into the boiler 5 without manual addition, thereby improving the efficiency of coal feeding and adding, saving time and effort. At the same time, personnel do not need to approach the boiler 5 to avoid burns. By starting the electric push rod 4 to drive the push plate 401 to push, the coal at the bottom can be pushed into the ramp plate 101, thereby avoiding material waste and eliminating the need for manual cleaning of the bottom coal.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
