[0016] Embodiment 1

[0017] As Figure 1 - Figure 2As shown in the figure, in this embodiment, a chain-type metering feeder is provided, which includes a frame 1. A feed hopper 2 is installed on the frame 1. A driving shaft and a driven shaft are rotatably arranged on the frame 1. A motor 3 is installed on the frame 1. The rotating shaft of the motor 3 is connected to the driving shaft. Two driving sprockets are sleeved on the driving shaft. Two driven sprockets are sleeved on the driven shaft. One driving sprocket and one driven sprocket form a sprocket group. A chain is sleeved on the sprocket group. An annular chain belt is connected between the two chains. The annular chain belt is inclined upward as a whole in the direction from left to right. The feed hopper 2 is located above the bottom end of the annular chain belt. A discharge chamber 4 is provided inside the frame 1. The top end of the annular chain belt is located inside the discharge chamber 4. The bottom of the discharge chamber 4 is connected to a blanking pipe 5. A material distributor 6 is provided on the frame 1. The material distributor 6 can rotate and can horizontally move in the left-right direction.

[0018] In this embodiment, a feed hopper 2 is installed on the frame 1. A driving shaft and a driven shaft are rotatably arranged on the frame 1. Driving sprockets and driven sprockets are respectively installed on the driving shaft and the driven shaft. Chains are connected to the driving sprockets and the driven sprockets. An annular chain belt is connected between the two chains. The top end of the annular chain belt is located inside the discharge chamber 4. The bottom end of the discharge chamber 4 is connected to a blanking pipe 5. The blanking pipe 5 is located above the belt conveyor. During use, fuel enters from the feed hopper 2 and falls onto the annular chain belt. The motor 3 works to drive the annular chain belt to move, causing the fuel to rise and be discharged from the discharge chamber 4. Then the fuel falls from the blanking pipe 5 onto the belt conveyor, and the belt conveyor conveys the fuel to the boiler feed hopper. A material distributor 6 is provided on the frame 1. When the material distributor 6 rotates to distribute materials, it also plays a role in limiting the height. The material distributor 6 can move left and right to adjust the distance between it and the annular chain belt, thereby adjusting the discharge amount, so that the fuel can be discharged according to the demand of the boiler, preventing the feeding equipment from bridging and improving the stability of boiler feeding.

[0019] In this embodiment, the material distributor 6 includes a rotating shaft. A number of material distribution rulers are provided on the rotating shaft. The two ends of the rotating shaft are respectively rotatably arranged on two bearing seats 7. Strip-shaped holes are opened on both the front plate and the rear plate of the frame 1. The rotating shaft passes through the two strip-shaped holes. The two bearing seats 7 are respectively detachably connected to the front plate and the rear plate of the frame 1. One end of the rotating shaft is connected to the driving shaft of a rotating motor 8.

[0020] In this embodiment, the bearing seat 7 is connected to the frame 1 by bolts.

[0021] In this embodiment, the material distributor 6 is driven by the rotating motor 8 to rotate. When adjusting the left-right position of the material distributor 6, the bolts connecting the bearing seat 7 to the frame 1 are removed, then the bearing seat 7 is moved left and right, and then the bearing seat 7 is connected to the frame 1 again, so as to realize the adjustment of the left-right position of the material distributor 6, and further adjust the distance between the material distributor 6 and the annular chain belt.

[0022] In this embodiment, two driving motors 9 are arranged in the blanking pipe 5. The two driving motors 9 are distributed in the left-right direction. A feeding baffle 10 is connected to the output shaft of the driving motor 9. The feeding baffle 10 can rotate in a vertical plane. In this embodiment, two driving motors 9 are arranged, and a feeding baffle 10 is connected to the output shaft of the driving motor 9. By rotating the driving motor 9, the position of the feeding baffle 10 can be adjusted, so that the fuel can fall from between the two feeding baffles 10 onto the belt conveyor. In this way, no matter where the fuel thrown from the endless chain belt falls in the blanking pipe 5, it can be ensured that the fuel falls at the middle position of the belt conveyor, realizing the uniform distribution of the fuel.

[0023] In this embodiment, the strip-shaped holes are arranged horizontally.
