AI Technical Summary
In traditional hoppers, materials tend to accumulate on the inclined surface, leading to blockages. The high speed of material sliding down the conveyor belt causes severe wear, and the impact force between the material and the belt is significant.
Design a central hopper with a chute plate at a 60° angle to the horizontal plane, reinforced with ceramic and steel linings for wear resistance, and equipped with an exciter motor and an air cannon. The exciter motor automatically discharges material, and the air cannon clears blockages, reducing wear and clogging.
It enables materials to slide smoothly, extends the service life of the hopper, reduces wear, prevents blockage, facilitates maintenance, and reduces the impact of equipment vibration.

CONCRETE EMBODIMENT
[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0018] like Figs. 1-2 As shown, a central hopper for a stacker-reclaimer includes an upper hopper 01, a middle hopper 02, a lower hopper 03, and a discharge port 04. The upper hopper 01, middle hopper 02, lower hopper 03, and discharge port 04 are connected sequentially from top to bottom. The upper hopper 01 is a cavity structure formed by welding a chute 1, two side plates 5, and an upper front plate 2. The middle hopper is a cavity structure formed by welding a chute 1, two side plates 5, and a middle front plate 3. The lower hopper 03 is a cavity structure formed by welding a chute 1, two side plates 5, and a lower front plate 4. The upper front plate 2, middle front plate 3, and lower front plate 4 are connected sequentially from top to bottom. The chute 1 forms a 60° angle with the horizontal plane. Several ceramic lining plates 6 are bolted to the chute 1 by bolts 20. Ceramic lining plates 6 are also installed on the inner side of the discharge port 04 opposite to the chute 1. The side plate 5 is bolted with several steel lining plates 7 by bolts 23. An air cannon is installed at the lower part of the chute 1 of the lower hopper 03. The air cannon 8 is equipped with an airflow nozzle 9 that is inserted into the discharge port 04. An excitation motor 10 is installed on the outer side of the lower front plate 4 of the lower hopper 03. A pressure sensor 11 is installed on the inner side of the discharge port 04 on the same side as the air cannon 8. A position sensor 12 is installed on the top inner side of the upper front plate 2 of the upper hopper 01. Support plates 13 are installed on the outer sides of the chute 1 and the middle front plate 3 of the middle hopper 03. A pair of metal springs 14 are installed at the bottom of the support plates 13. The bottom of the metal springs 14 is connected to the stacker-reclaimer through a connecting plate 15. A cleaning port 16 is opened on the lower front plate 4 of the lower hopper 03. A sealing plate 17 is installed on the cleaning port 16.
[0019] The discharge port 04 is a rectangular cavity structure welded from four steel plates.
[0020] The upper front plate 2 is perpendicular to the horizontal plane, the middle front plate 3 is at an angle of 60~65° to the horizontal plane, the lower front plate 4 is at an angle of 65~70° to the horizontal plane, and the middle front plate 3 and the lower front plate 4 are connected in a parabolic shape.

The material travels along the chute 1 through the middle hopper 02 and the lower hopper 03, finally falling from the discharge port 04 onto the conveyor belt. When material accumulates to a certain height in the hopper, to prevent blockage, the position sensor 12 measures the height of the material in the hopper. When the set height is reached, the excitation motor 13 is automatically started to vibrate and unload the material. When the material in the hopper falls below a certain height, the excitation motor 13 is automatically turned off. When material forms a blockage at the discharge port and cannot be unloaded normally, the pressure sensor 11 measures the pressure. When the set pressure value is reached, the air cannon 8 is automatically started to impact the blocked material with high-pressure airflow to restore normal material unloading. After the material is unloaded normally, the pressure sensor 11 measures that the pressure value has decreased to the set value and the air cannon 8 is automatically turned off.
