Technical Field

[0001] The utility model relates to the technical field of bucket wheel stacker reclaimers, in particular to a discharging device of a bucket wheel stacker reclaimer. Background Art

[0002] Bucket wheel stacker reclaimer is a large-scale bulk material loading and unloading equipment with high efficiency and continuous operation. It is mainly used in coal and ore storage yards in industries such as power, metallurgy, coal, building materials and chemical industry. Bucket wheel stacker reclaimer is mainly composed of bucket wheel mechanism, cantilever belt conveyor, boom, balance beam, slewing platform, door seat, tail car, slewing mechanism, pitching mechanism and walking mechanism. The bucket wheel mechanism is installed at the front end of the boom to dig materials.

[0003] When conveying wet coal, the existing bucket wheel stacker reclaimer tends to adhere to the conveying platform between the bucket wheel and the conveyor belt.

[0004] In order to solve the above problems, the existing Chinese patent with publication number CN 218057537 U discloses a bucket wheel unloading device of a bucket wheel stacker and reclaimer, including a bucket wheel, a fixed cover and a conveyor belt, a unloading assembly and a knocking assembly are arranged on one side of the fixed cover, a unloading plate and a connecting frame are arranged inside the unloading assembly, the unloading plate extends into the interior of the bucket wheel, the unloading plate is fixedly connected to the fixed cover through the connecting frame, and the knocking assembly is movably connected to the unloading plate, which specifically relates to the field of bucket wheel stackers and reclaimers. The bucket wheel unloading device of the bucket wheel stacker and reclaimer, before the bucket wheel stops working, drives the connecting shaft to rotate forward and reversely through the operation of the motor, and the forward and reverse rotation of the connecting shaft drives the first cam and the second cam to swing, and the first cam and the second cam can knock the unloading plate when they swing, so that the wet coal layer on the unloading plate can vibrate and fall into the conveyor belt, solving the problem that the wet coal layer adhered to the unloading plate is difficult to clean.

[0005] However, the above patent still has some shortcomings. There may be large pieces of material, which may rush towards the belt with a large speed and impact force when passing through the unloading device, causing it to rush out of the belt and pose a personal threat to nearby workers.

[0027] The impact rod 8 and the screw 7 are both provided with a plurality of them, and the top of the material splash-proof box 5 is rotatably connected with a closed door 10. The closed door 10 is installed on the material splash-proof box 5 for replacing the internal impact rod 8 when necessary.

[0028] The port of the material splash box 5 near the material guide plate 4 is provided with a splash-proof belt 11, which is composed of a plurality of rubber strips made of rubber material. The splash-proof belt 11 is installed at the port of the material splash box 5, and the splash-proof belt 11 is composed of a plurality of rubber strips made of rubber material, which can effectively prevent the material from splashing out of the material splash box 5 during the impact process.

[0029] The protruding rod 12 on the rotating shaft 6 is fixedly connected with a vertical rod 13 between the top of the receiving plate 3 and the inner wall of the material splash box 5. The vertical rod 13 is sleeved with an impact hammer 14.
