Description

Technical Field

[0001] The utility model belongs to the field of material transportation, in particular to a double-tail car transportation switching device for a bucket wheel stacker and reclaimer. Background Art

[0002] Bucket-wheel stackers are commonly used for stacking and reclaiming materials. Existing bucket-wheel stackers include a first and second tail car with conveyor belts, each with a ground conveyor belt positioned below the first and second tail cars. When transporting materials backward from the first tail car, the material can be transported from the first tail car to the second tail car or through the ground conveyor belt, depending on actual needs. Specifically, when materials need to be transported for stacking, the discharge end of the conveyor belt on the first tail car is raised at a certain angle, allowing the material to fall onto the upward-tilted conveyor belt on the second tail car after being transported by the conveyor belt on the first tail car. The material then continues to be transported upward to a certain height before being dropped for stacking. When materials only need to be transported forward directly, the conveyor belt on the first tail car does not need to be raised; it is directly received by the ground conveyor belt and transported forward. However, this method requires the conveyor belt on the first tail car to be frequently raised and lowered, resulting in poor stability and high energy consumption. Utility Model Content

[0019] like Figure 1-4As shown, the bucket wheel stacker and reclaimer double tail car conveying switching device includes a first tail car 1 and a second tail car 2 which are arranged in sequence, the first tail car 1 is provided with a first conveyor belt 1.1 for loading materials through a first bracket 1.3, and the second tail car 2 is provided with a second conveyor belt 2.1 for transporting materials to stacking through a second bracket 2.2. A ground conveyor belt 3 is also set up below the first tail car 1 and the second tail car 2, and a walking wheel 1.2 is provided below the first tail car 1, and a hydraulic cylinder 4 is fixedly provided on the first tail car 1, and the movable end of the hydraulic cylinder 4 is fixedly connected to the second tail car 2; above the second tail car 2, a first material receiving hopper 5 and a second material receiving hopper 6 are set up in sequence from front to back, the first material receiving hopper 5 is located near the first tail car 1, the first material receiving hopper 5 is located above the ground conveyor belt 3 and there is no obstruction in the middle, the second material receiving hopper 6 is located above the feeding end of the second conveyor belt 2.1, and the discharging end of the first conveyor belt 1.1 is higher than the first material receiving hopper 5 and the second material receiving hopper 6.

[0020] The ground conveyor belt 3 and the first conveyor belt 1.1 on the first tail vehicle 1 are the same conveyor belt.

[0021] The length of the lower end of the first receiving hopper 5 is longer than that of the lower end of the second receiving hopper 6 so as to be closer to the ground conveyor belt 3 to avoid material scattering or dust.

[0022] The second receiving hopper 6 is fixedly mounted on the second bracket 2 . 2 on the second tail vehicle 2 .
