[0003] In the prior art, when coal is used as fuel in a thermal power station, a conveyor belt is used to load and transport the coal, and the coal is transported at a uniform speed so that the coal can be efficiently and safely transported to the boiler to provide the necessary fuel for the power generation process of the thermal power station.

[0004] However, in the process of transporting coal, the coal on the conveyor belt piles up and is transported into the boiler together. The piled coal blocks each other, the contact area between the coal and the air in the boiler is reduced, and the combustion efficiency is affected. Utility Model Content

[0005] The utility model aims to propose a thermal power fuel loading and transmission device to solve the problem in the background technology that coal is piled up and loaded on a conveyor belt and transported into a boiler, thereby reducing combustion efficiency.

[0013] Optionally, the force storage delay assembly includes a ramming rod, a triangular block, a fixed block and a limit block. The bottom of the ramming rod is fixedly connected to the spring telescopic rod, the arc surface of the ramming rod is fixedly installed with symmetrically arranged triangular blocks, the bottom of the limit block is clamped with the triangular block, the side of the middle block is fixedly installed with a fixed block, and the limit block slides left and right in the fixed block.

[0030] Example 1

[0031] This embodiment proposes a thermal electric fuel loading and transmission device, such as Figure 1 As shown, it includes two symmetrically arranged assembly line frames 1, and the two assembly line frames 1 are rotatably connected to the opposite sides with conveying rollers 5, and the conveying belt 2 is sleeved on the arc surface of the conveying roller 5. Baffles 3 are fixedly installed on the top of the assembly line frame 1 and on both sides of the conveying belt 2, and motors 4 are fixedly installed on the sides of the assembly line frame 1 and at the ends of the conveying rollers 5. The baffles 3 prevent coal from falling from the sides of the conveying belt 2. Friction patterns are provided on the conveying belt 2, and the friction patterns increase the friction between the conveying belt 2 and the coal to prevent the coal from rolling along the conveying belt 2.

[0032] like Figure 2 and 3 As shown, a dispersion component 6 is provided on the side of the assembly line frame 1 and located inside the conveyor belt 2. The dispersion component 6 includes an intermediate block 61, an electric push rod 63, a top plate 64 and a spring telescopic rod 65. The intermediate block 61 is fixedly installed on the side of the assembly line frame 1 and located at the center of the conveyor belt 2. The electric push rod 63 is fixedly installed on the side of the intermediate block 61. The pressure sensor 62 is fixedly installed on the top of the intermediate block 61. The top of the pressure sensor 62 is in contact with the conveyor belt 2. The pressure sensor 62 is electrically connected to the electric push rod 63 through a controller.

[0033] The coal is conveyed to the pressure sensor 62 by the conveyor belt 2. When the pressure sensor 62 detects that the weight of the coal there exceeds a set value, it means that the coal is piled up there. The pressure sensor 62 extends the electric push rod 63 through the controller.

[0034] like Figure 4 As shown, a top plate 64 is fixedly installed on the top of the electric push rod 63, and the top plate 64 is parallel to the ground. A spring telescopic rod 65 is fixedly installed on the top of the top plate 64. A plurality of spring telescopic rods 65 are arranged and are equidistantly distributed in a straight line along the top plate 64. A force storage delay component 7 is arranged on the top of the spring telescopic rod 65.

[0035] The electric push rod 63 extends and uses the spring telescopic rod 65 to lift the power storage delay component 7, and uses the power storage delay component 7 to hit the conveyor belt 2, so that the coal accumulated on the conveyor belt 2 is spread around the collision point between the power storage delay component 7 and the conveyor belt 2, and the accumulated coal is dispersed. The elasticity of the spring telescopic rod 65 makes the power storage delay component 7 have a buffering effect when it hits the conveyor belt 2, and multiple spring telescopic rods 65 increase the collision points of the power storage delay component 7.

[0036] like Figure 2 and 3As shown, the electric push rod 63 is located at the side of the assembly line frame 1 and close to the right end of the assembly line frame 1. A boiler is provided at the right end of the assembly line frame 1. When the power storage delay assembly 7 hits the coal piled on the conveyor belt 2, the coal is knocked away due to the impact of the power storage delay assembly 7, and the knocked-away coal enters the boiler, further increasing the distance between the coals and improving the combustion effect.

[0037] In this embodiment, the weight of the coal at that location is detected by the pressure sensor 62. When the coal is piled together and the weight exceeds the set value, the electric push rod 63 extends and uses the spring telescopic rod 65 to make the power storage delay component 7 hit the conveyor belt 2. The coal accumulated on the conveyor belt 2 is spread around the collision point between the power storage delay component 7 and the conveyor belt 2, so that the accumulated coal is dispersed and the combustion effect is improved.

[0038] Example 2

[0039] Based on Example 1, this example proposes a thermal power fuel loading and transmission device, such as Figure 3 and 4 As shown, the force storage delay component 7 includes a ramming rod 71, a triangular block 72, a fixed block 73 and a limit block 74. The bottom of the ramming rod 71 is fixedly connected to the spring telescopic rod 65. The triangular blocks 72 symmetrically arranged are fixedly installed on the arc surface of the ramming rod 71. The bottom of the limit block 74 is clamped with the triangular block 72. The fixed block 73 is fixedly installed on the side of the intermediate block 61. The limit block 74 slides left and right in the fixed block 73. The top of the ramming rod 71 adopts a hemispherical structure, and a coil spring 75 is elastically connected between the limit block 74 and the fixed block 73.

[0040] The limit block 74 is used to prevent the tamping rod 71 and the triangular block 72 from moving upward, so that there is a delay when the tamping rod 71 moves upward, so that the accumulated coal has time to move from above the pressure sensor 62 to above the tamping rod 71. At the same time, the fixed block 73 and the limit block 74 cooperate to compress the spring telescopic rod 65, and the compressed spring telescopic rod 65 accumulates force. When the accumulated coal moves to above the tamping rod 71, the elastic force of the spring telescopic rod 65 is greater than the resistance of the coil spring 75 and the limit block 74 to the triangular block 72. At this time, the tamping rod 71 quickly bounces up and hits the conveyor belt 2.

[0041] like Figure 4 As shown, the end of the limit block 74 adopts a triangular structure, the shape of the end of the limit block 74 is the same as that of the triangular block 72, and the inclination angle of the bottom slope of the limit block 74 is the same as the inclination angle of the top slope of the triangular block 72. The resistance to the upward movement of the ramming rod 71 and the triangular block 72 is greater than the resistance to the downward movement, so that the ramming rod 71 is reset.

[0042] In this embodiment, the fixing block 73 and the limiting block 74 cooperate to prevent the tamping rod 71 from moving upward, so that the spring telescopic rod 65 is compressed. When the accumulated coal moves to the top of the tamping rod 71, the elastic force of the spring telescopic rod 65 is greater than the resistance of the coil spring 75 and the limiting block 74 to the triangular block 72. At this time, the tamping rod 71 quickly bounces up to hit the conveyor belt 2, thereby improving the impact effect and playing a delay role, so that the accumulated coal has time to move to the top of the tamping rod 71.

[0043] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
