Description

Technical Field

[0001] The present utility model relates to the field of bucket wheels, and specifically to a bucket wheel device of a stacker-reclaimer. Background Art

[0002] As a large-scale continuous loading and unloading device, the bucket wheel stacker-reclaimer has been widely used in the fields of bulk cargo ports, thermal power plants, mines, etc. due to its high operation efficiency, strong stacking and reclaiming capacity, and low loading and unloading cost.

[0003] At present, the same-sized pointed teeth are used for the material-taking buckets of the bucket wheel device, which often have problems such as insufficient digging force and uneven material grasping, resulting in low operation efficiency and easy damage to the materials. Content of the Utility Model

[0004] In order to overcome the above deficiencies, the present utility model provides a bucket wheel device of a stacker-reclaimer.

[0005] The technical solution adopted by the present utility model:

[0006] A bucket wheel device of a stacker-reclaimer includes a boom. A dust-proof cover is fixedly connected to the left side of the rear end of the boom. A bearing is fixedly sleeved on the outer wall of the dust-proof cover. The outer ring of the bearing is fixedly sleeved with a rotating cylinder. The dust-proof cover is rotationally connected with the rotating cylinder through the bearing. A motor is fixedly installed inside the dust-proof cover. The left end of the output shaft of the motor is fixedly connected to the left inner wall of the rotating cylinder. A plurality of material-taking buckets are fixedly connected to the outer wall of the rotating cylinder. The material-taking buckets are evenly distributed at equal angles around the outer wall of the rotating cylinder. The material-taking buckets are in clearance fit with the outer wall of the rotating cylinder. The openings of the material-taking buckets face clockwise. A plurality of small pointed teeth and three large pointed teeth are evenly fixedly connected to the outer edge of the opening of the material-taking bucket. The three large pointed teeth are distributed at the side and the middle of the outer edge of the opening of the material-taking bucket.

[0007] Advantages of the Present Utility Model

[0008] By arranging small pointed teeth and large pointed teeth on the outer edge of the opening of the material-taking bucket, especially the arrangement of the large pointed teeth, the present utility model can break the surface first during digging, significantly enhancing the digging ability of the bucket wheel, enabling it to dig and grasp materials more effectively, and improving the working efficiency.

[0016] As Figure 1-6 shown: A bucket wheel device of a stacker-reclaimer, including a boom 1; A dust cover 2 is fixedly connected to the left side of the rear end of the boom 1, a bearing 3 is fixedly sleeved on the outer wall of the dust cover 2, a rotary drum 4 is fixedly sleeved on the outer ring of the bearing 3, the dust cover 2 is rotatably connected to the rotary drum 4 through the bearing 3, a motor 5 is fixedly installed inside the dust cover 2, the left end of the output shaft of the motor 5 is fixedly connected to the left inner wall of the rotary drum 4, a plurality of material fetching hoppers 6 are fixedly connected to the outer wall of the rotary drum 4, the material fetching hoppers 6 are evenly distributed at equal angles around the outer wall of the rotary drum 4, the material fetching hoppers 6 are in clearance fit with the outer wall of the rotary drum 4, the openings of the material fetching hoppers 6 face clockwise, a plurality of small pointed teeth 7 and three large pointed teeth 8 are evenly fixedly connected to the outer edge of the openings of the material fetching hoppers 6, and the three large pointed teeth 8 are distributed at the side and the middle of the outer edge of the opening of the material fetching hopper 6.

[0017] During operation, the motor 5 is started, and the motor 5 drives the rotary drum 4 fixedly connected thereto to rotate inside the dust cover 2 through its output shaft. Since the material fetching hoppers 6 are fixedly connected to the outer wall of the rotary drum 4, these material fetching hoppers 6 make a circular motion around its axis as the rotary drum 4 rotates.

[0018] Each material fetching hopper 6 is designed with an opening facing clockwise, and a plurality of small pointed teeth 7 and three large pointed teeth 8 are evenly fixedly connected to the outer edge of its opening. As the material fetching hopper 6 rotates, the opening part thereof will contact the material to be excavated.

[0019] Due to the existence of the small pointed teeth 7 and the large pointed teeth 8, the large pointed teeth 8 break the surface first, can cut into the material more effectively, and can provide stronger excavation force and better material grasping effect.

[0020] As the rotary drum 4 continues to rotate, the material fetching hoppers 6 continuously dig up the material and bring it into the bucket wheel device, completing the stacking and fetching operation of the material. The present utility model only protects the mechanical part, and the functions realized through the software control part related thereto are not within the protection scope of the present utility model.
