[0002] Bridge-type impeller feeders are continuous bulk material conveying equipment widely used in industries such as thermal power generation, coal, metallurgy, and ports. Their core function is to uniformly and quantitatively transport lumpy and granular bulk materials (such as coal and ore) from storage silos (or stockyards) to subsequent belt conveyors, achieving efficient material transfer and distribution. Due to their large conveying capacity, stable operation, and high degree of automation, they have become one of the key pieces of equipment in bulk material handling systems.

[0003] Bridge-type impeller coal feeders are prone to coal spillage during the coal feeding process, resulting in extremely dusty working environments that seriously affect the civilized production and environmental parameters of the equipment. Large amounts of spilled coal require manual cleaning, increasing the workload of personnel. Large coal chunks falling from heights pose a risk of injuring equipment and pedestrians. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a coal receiving device for an impeller feeder, which aims to improve the problems of large coal leakage requiring manual cleaning, increasing the workload of personnel, and the risk of large coal blocks falling from heights injuring equipment and pedestrians.

A buffer plate is inclinedly arranged inside the coal receiving box, with the bottom end of the buffer plate close to the discharge port. An elastic buffer element is arranged between the inner bottom of the coal receiving box and the buffer plate.

[0007] In one specific implementation, the two ends of the elastic buffer are detachably connected to the coal receiving box and the buffer plate, respectively.

[0008] In one specific implementation, a first mounting plate and a second mounting plate are fixedly connected to the opposite surfaces of the coal receiving box and the buffer plate, respectively, and the two ends of the elastic buffer are detachably connected to the first mounting plate and the second mounting plate, respectively.

[0009] In one specific implementation, the elastic buffer includes a buffer portion, with a first connecting plate and a second connecting plate respectively connected to both ends of the buffer portion. The first connecting plate is detachably connected to the first mounting plate, and the second connecting plate is detachably connected to the second mounting plate.

[0010] In one specific implementation, a first connecting bolt is provided between the first connecting plate and the first mounting plate.

[0012] In one specific implementation, the bottom of the coal receiving box is provided with an inclined section, and the inclined direction of the inclined section is the same as the inclined direction of the buffer plate.

[0013] In one specific implementation, an inspection door is installed at the inspection port.

[0014] In one specific implementation, the access door is hinged to the access opening and can be opened and closed.

[0015] In one specific implementation, the bottom of the coal receiving box is provided with support legs.

[0016] Beneficial effects:

[0017] 1. By combining the coal receiving box, buffer plate and elastic buffer, the falling coal can be collected, reducing dust in the working environment and eliminating the need for manual cleaning, thus preventing injuries from falling coal.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0026] Please see Figures 1-4 This application provides a coal receiving device for an impeller feeder, including a coal feeder 10 and a coal receiving assembly 20.

[0027] The specific working principle and structure of the coal feeder 10 are existing technologies and will not be described in detail here.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The coal receiving assembly 20 includes a coal receiving box 210 with an open top. The coal receiving box 210 is located at the point where coal blocks fall from the coal feeder 10. An inspection port 211 and a discharge port 212 are respectively opened on both sides of the coal receiving box 210. Specifically, a belt conveyor is connected to the discharge port 212, which can transport the coal blocks discharged from the discharge port 212 to the raw coal bunker, thereby improving the efficiency of coal block recycling. The discharge port 212 is located at the bottom of the side wall of the coal receiving box 210. A buffer plate 220 is inclinedly arranged inside the coal receiving box 210, with the bottom end of the buffer plate 220 close to the discharge port 212. An elastic buffer element 230 is arranged between the inner bottom of the coal receiving box 210 and the buffer plate 220. The coal receiving box 210 is positioned at the point where coal blocks fall from the coal feeder 10. When the coal feeder 10 is running, the falling coal blocks will fall into the coal receiving box 210, contact the buffer plate 220, and then fall to the discharge port 212 for discharge. Through the cooperation of the coal receiving box 210, the buffer plate 220, and the elastic buffer element 230, the falling coal blocks can be collected, reducing dust in the working environment without requiring manual cleaning and preventing injury from falling coal blocks. Furthermore, the service life of the coal receiving box 210 can be extended, and the noise generated when coal blocks fall can be reduced. The inspection port 211 allows for maintenance of the buffer plate 220 and the elastic buffer element 230, enabling the replacement of these components.

[0029] In this embodiment, the two ends of the elastic buffer 230 are detachably connected to the coal receiving box 210 and the buffer plate 220, respectively. A first mounting plate 270 and a second mounting plate 280 are fixedly connected to the opposite surfaces of the coal receiving box 210 and the buffer plate 220, respectively. The two ends of the elastic buffer 230 are detachably connected to the first mounting plate 270 and the second mounting plate 280, respectively. The elastic buffer 230 includes a buffer portion 231, and the two ends of the buffer portion 231 are connected to a first connecting plate 232 and a second connecting plate 233, respectively. The first connecting plate 232 is detachably connected to the first mounting plate 270, and the second connecting plate 233 is detachably connected to the second mounting plate 280. A first connecting bolt is provided between the first connecting plate 232 and the first mounting plate 270. A second connecting bolt is provided between the second connecting plate 233 and the second mounting plate 280. The provision of the first and second connecting bolts allows the buffer portion 231 and the buffer plate 220 to be replaced, improving the buffering effect during coal receiving.

[0030] In its specific design, the bottom of the coal receiving box 210 is provided with an inclined section 250, and the inclined direction of the inclined section 250 is the same as the inclined direction of the buffer plate 220. The inclined section 250 allows for the rapid discharge of collected coal chunks.

[0031] In this embodiment, an inspection door 240 is installed at the inspection port 211. The inspection door 240 is hinged at the inspection port 211 and can be opened and closed. The inspection door 240 can be used to seal the inspection port 211, reducing coal dust emissions.

[0032] The bottom of the coal receiving box 210 is equipped with support legs 260.

[0033] Working principle of the coal receiving device of the impeller feeder:

[0034] The coal receiving box 210 is positioned at the point where coal blocks fall from the coal feeder 10. When the coal feeder 10 is running, the falling coal blocks will fall into the coal receiving box 210, contact the buffer plate 220, and then fall to the discharge port 212 for discharge. Through the cooperation of the coal receiving box 210, the buffer plate 220, and the elastic buffer element 230, on the one hand, the falling coal blocks can be collected, reducing dust in the working environment and eliminating the need for manual cleaning, preventing injury from falling coal blocks; on the other hand, it can also extend the service life of the coal receiving box 210 and reduce the noise generated when coal blocks fall. The inspection port 211 allows for maintenance of the buffer plate 220 and the elastic buffer element 230, enabling the replacement of these components.
