[0002] Coal blending is one of the processes in coking coal and power coal blending and boiler preparation. There are many types of coal used in coal blending. Applying coal blending technology can not only ensure the quality of coke, but also make rational use of coal resources, save high-quality coking coal, and expand coking coal resources. Coal blending technology involves many process properties of coal, coking characteristics, and the combination properties of ash, sulfur, and volatile matter, as well as the coking mechanism of coal. There are two methods of coal blending: coal blending bin blending and open-air coal blending plant blending. Commonly used equipment includes coal blending pans, electromagnetic vibrating feeders, and automatic coal blending devices.
[0003] With the increasing demand for automation and precise control in the coal industry, traditional manual coal blending methods can no longer meet the requirements for coal conveying volume, blending accuracy and efficiency in the production process. The supply of materials is unstable, and there are often blockages or flow fluctuations in coal during the conveying process, resulting in low production efficiency and even affecting the normal operation of subsequent processes.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the motor is started by activating the control panel. The motor drives the rotating shaft and rotating roller to rotate, which in turn drives the conveyor belt to transport the coal blocks. The set limit plate blocks and limits the coal blocks. The hydraulic rod is activated by activating the control panel. The hydraulic rod drives the second connecting shaft, the second connecting block and the feeding plate to move, so that the feeding plate rotates inside the connecting frame.

[0022] 2. In this utility model, coal blocks are poured into the feed inlet and the fixed box, falling onto the upper side of the guide plate and then onto the upper side of the weighing plate. A weight sensor detects the weight of the coal blocks. The operator observes the weight of the coal blocks through the control panel and activates the control panel to start the push rod. The push rod moves the fixed block and the weighing plate, scraping off the coal blocks on the upper side of the weighing plate and discharging them from the discharge port onto the upper side of the conveyor belt. This allows for precise control of the coal flow rate, ensuring that each type of coal is accurately transported according to a predetermined ratio during the coal blending process, thus achieving precise coal blending.

The outlet is connected to a second connecting block 14 via a second connecting shaft 13. A feeding plate 15 is fixedly connected to the left side of the second connecting block 14. A connecting frame 16 is fixedly connected to the upper left side of the conveying frame 2. The feeding plate 15 is rotatably connected to the connecting frame 16.

A rotating roller 6 is fixedly connected to the outside of the rotating shaft 5. A conveyor belt 7 is provided outside the rotating roller 6. Evenly distributed limiting plates 8 are fixedly connected to the outside of the conveyor belt 7.
[0031] The control panel 19 is activated to start the motor 4, which in turn drives the rotating shaft 5 and the rotating roller 6 to rotate, thereby driving the conveyor belt 7 to transport the coal blocks. The limit plate 8 is set to block and limit the coal blocks. The control panel 19 is activated to start the hydraulic rod 12, which in turn drives the second connecting shaft 13, the second connecting block 14 and the feeding plate 15 to move, so that the feeding plate 15 rotates inside the connecting frame 16, which can continuously and stably supply coal and adjust the feeding and conveying angle of the coal blocks.
[0032] Reference Figure 1 , Figure 2 , Figure 3 A fixed box 18 is fixedly connected to the upper right side of the base plate 1. A control panel 19 is fixedly connected to the right side of the fixed box 18. A feed inlet 20 is fixedly connected to the upper side of the fixed box 18. Guide plates 21 are fixedly connected to the four corners inside the fixed box 18. A fixed frame 22 is fixedly connected to the left side of the fixed box 18. Weighing components are fixedly connected to both sides inside the fixed frame 22. The weighing components are used for automatic weighing of coal. A discharge port 28 is fixedly connected to the lower side of the weighing components. The weighing components include a push rod 23, which is fixedly connected to the inside of the fixed frame 22. A fixed block 24 is fixedly connected to the output end of the push rod 23. A weighing plate 25 is fixedly connected to the right side of the fixed block 24. A weight sensor 26 is fixedly connected to the lower side of the weighing plate 25.
[0033] By pouring coal into the feed inlet 20 and the fixed box 18, it falls onto the upper side of the guide plate 21 and then onto the upper side of the weighing plate 25. The weight sensor 26 senses the weight of the coal. The operator observes the weight of the coal through the control panel 19. By activating the control panel 19, the push rod 23 is activated. The push rod 23 moves the fixed block 24 and the weighing plate 25, causing the weighing plate 25 to slide inside the channel 27. This scrapes off the coal on the upper side of the weighing plate 25 and discharges it from the discharge port 28 onto the upper side of the conveyor belt 7, thus enabling precise control of the coal flow rate.
[0034] Reference Figure 2 , Figure 3 , Figure 4 A through slot 27 is provided on the left side of the fixed box 18. A weighing plate 25 and a weight sensor 26 are slidably connected inside the through slot 27. A baffle plate 17 is fixedly connected to the right side of the inside of the conveyor frame 2. The discharge port 28 is located on the upper side of the conveyor belt 7. The two rotating shafts 5 and the rotating roller 6 are rotatably connected inside the conveyor frame 2.
[0035] A through slot 27 is provided on the left side of the fixed box 18. A weighing plate 25 and a weight sensor 26 are slidably connected inside the through slot 27, which serves to support and limit the weighing plate 25 and the weight sensor 26. A baffle plate 17 is fixedly connected to the inside right side of the conveyor frame 2, which serves to prevent coal blocks from falling. A discharge port 28 is set on the upper side of the conveyor belt 7, which facilitates the conveying of coal blocks. Two rotating shafts 5 and rotating rollers 6 are rotatably connected inside the conveyor frame 2, which serves to support and limit the rotating shafts 5 and rotating rollers 6.
[0036] Working Principle: When using this device, coal blocks are poured into the feed inlet 20, enter the fixed box 18, fall onto the upper side of the guide plate 21, and then onto the upper side of the weighing plate 25. The weight sensor 26 senses the weight of the coal blocks. The operator observes the weight of the coal through the control panel 19. By manually opening the control panel 19, the push rod 23 is activated, which moves the fixed block 24. The movement of the fixed block 24 moves the weighing plate 25, causing it to slide inside the channel 27. This scrapes off the coal blocks on the upper side of the weighing plate 25, which are then discharged from the discharge port 28 onto the upper side of the conveyor belt 7. This achieves precise control of the coal flow rate, ensuring the smooth operation of the coal blending process. Each type of coal is precisely fed according to a predetermined ratio, thus achieving precise coal blending. By manually opening the control panel 19, the control panel 19 starts the motor 4, which in turn drives the rotating shaft 5 to rotate. The rotating shaft 5 then drives the rotating roller 6, which in turn drives the conveyor belt 7 to transport the coal blocks. The set limit plate 8 blocks the coal blocks and limits their movement. The control panel 19 starts the hydraulic rod 12, which in turn moves the second connecting block 14 connected to the second connecting shaft 13. The movement of the second connecting block 14 moves the feeding plate 15, causing the feeding plate 15 to rotate inside the connecting frame 16. This achieves continuous and stable coal supply and allows for adjustment of the feeding and conveying angle of the coal blocks, ensuring production stability.
