[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a cantilever bucket wheel stacker-reclaimer, including a traveling mechanism 1, a mounting frame 11 mounted on the traveling mechanism 1, and a conveying mechanism 2 mounted on the traveling mechanism 1 for conveying coal, and further including:

[0026] The bucket wheel mechanism 3 is located on the side of the mounting frame 11 away from the traveling mechanism 1, and is used to excavate coal materials;

[0027] The material guiding mechanism 4 is installed on the mounting frame 11 and located below the discharge port of the bucket wheel mechanism 3. It is used to transport the coal dug by the bucket wheel mechanism 3 to the conveying mechanism 2.

[0028] It should be noted that during operation, the moving walking mechanism 1 moves the reclaimer to the coal stacking area. Then, the walking mechanism 1 drives the bucket wheel mechanism 3 to contact the coal. During the movement of the bucket wheel mechanism 3, the coal is collected in the bucket wheel mechanism 3 and then transported to the guiding mechanism 4. The guiding mechanism 4 can evenly transport the coal to the conveying mechanism 2 for transport. This cantilever bucket wheel stacker-reclaimer can dig coal materials from all directions, greatly improving digging efficiency. The guiding mechanism 4 can transport the material from the bucket wheel mechanism 3 to the conveying mechanism 2, avoiding the problems of blockage and spillage of material during the guiding process. It realizes the integrated operation of digging, guiding and conveying, greatly improving the operation efficiency. At the same time, it reduces the problems of spillage and blockage of material during the conveying process, improves the operation quality and reduces the production cost.

[0029] In one embodiment, a connecting plate 12 is provided between two mounting brackets 11, and a connecting bracket 13 is provided on the side of the connecting plate 12 away from the mounting brackets 11. A support ring 14 for supporting the bucket wheel mechanism 3 is provided on the connecting bracket 13.

[0030] This design connects the two mounting frames 11 via a connecting plate 12, forming a stable frame structure. This enhances the overall integrity of the upper structure of the cantilever bucket wheel stacker-reclaimer. The connecting frame 13 is located on the side of the connecting plate 12 away from the mounting frame 11, providing a stable mounting base for the support ring 14. The support ring 14 directly supports the bucket wheel mechanism 3, enabling it to withstand the large load generated by the bucket wheel mechanism 3 during digging. This ensures that the bucket wheel mechanism 3 maintains a stable posture during operation, reducing swaying and deviation, thereby improving the accuracy and stability of digging.

[0031] In one embodiment, the bucket wheel mechanism 3 includes a motor 38 mounted on a connecting plate 12, a rotating shaft 39 mounted on the power output end of the motor 38 and passing through the connecting plate 12, a connecting plate 33 mounted on the rotating shaft 39, a rotating frame 34 mounted on the connecting plate 33, a mounting ring 35 mounted on the outside of the rotating frame 34, a mounting plate 37 mounted on the mounting ring 35, and a bucket 36 mounted on the mounting plate 37. The buckets 36 are distributed at equal angles on the outside of the mounting ring 35. The mounting ring 35 is sleeved on the support ring 14. The support ring 14 has a discharge port 1401 for discharging material at a position above the rotating shaft 39.

[0032] A support sleeve 32 is fitted on the rotating shaft 39, and a support frame 31 is provided between the support sleeve 32 and the connecting frame 13.

[0033] This design allows the drive motor 38 to rotate the rotating shaft 39, which in turn causes the connecting plate 33 to rotate the rotating frame 34. This, in turn, causes the mounting ring 35 to rotate the bucket 36 outside the support ring 14, enabling the bucket 36 to dig up the coal. The buckets 36 are evenly distributed on the outside of the mounting ring 35. This layout allows the buckets 36 to dig the coal material from all directions during the rotation of the bucket wheel mechanism 3. Regardless of the shape or stacking method of the material pile, multiple buckets 36 can participate in the digging operation simultaneously, greatly improving the efficiency and comprehensiveness of digging, reducing dead zones, and ensuring that the coal material is fully extracted. The mounting ring 35 is fitted onto the support ring 14, which provides stable support for the mounting ring 35, allowing the bucket wheel mechanism 3 to maintain a stable posture during digging. A discharge port 1401 is provided above the rotating shaft 39 for material discharge. The excavated material can smoothly enter the guiding mechanism 4 through the discharge port 1401, avoiding the accumulation of material inside the bucket wheel mechanism 3. This design allows the excavation and guiding processes to be closely connected, improving the efficiency of material conveying, reducing the residence time of material in the bucket wheel mechanism 3, and reducing the risk of equipment failure caused by material accumulation. A support sleeve 32 is fitted on the rotating shaft 39, and a support frame 31 is provided between the support sleeve 32 and the connecting frame 13. This structure provides additional support for the rotating shaft 39, enhancing the rigidity and stability of the rotating shaft 39. During the rotation of the bucket wheel mechanism 3, it can effectively reduce the shaking and vibration of the rotating shaft 39, ensuring the smooth operation of the entire bucket wheel mechanism 3 and extending the service life of the equipment.

[0034] In one embodiment, the material guiding mechanism 4 includes a material guiding bin 41 located below the material discharge port 1401 on the support ring 14 and a material discharge box 42 located at the lower end of the material guiding bin 41, with the material discharge box 42 located above the conveying mechanism 2.

[0035] With this design, the guide bin 41 is positioned below the discharge port 1401 of the support ring 14, enabling it to promptly and accurately receive materials dug from the bucket wheel mechanism 3 and falling through the discharge port 1401. Its reasonable positioning design makes the transition of coal from the bucket wheel mechanism 3 to the guide bin 41 smoother, avoiding spillage and accumulation of materials during the falling process, and ensuring the continuity of material conveying. The discharge box 42 is located at the lower end of the guide bin 41 and above the conveying mechanism 2. This layout can accurately guide the materials in the guide bin 41 to the conveying mechanism 2, improving the accuracy and efficiency of material conveying, and ensuring that the conveying mechanism 2 can efficiently transport coal to the designated location.

[0036] In one embodiment, a belt drive mechanism 310 is provided on the side of the rotating shaft 39 away from the motor 38, and a conveying shaft 43 is provided on the guide bin 41. The conveying shaft 43 is connected to the belt drive mechanism 310. A spiral blade 44 is sleeved on the conveying shaft 43 at the position inside the guide bin 41. The belt drive mechanism 310 is supported by a drive wheel sleeved on the rotating shaft 39, a drive wheel provided on the conveying shaft 43, and a belt sleeved on the two drive wheels.

[0037] In this design, a belt drive mechanism 310 is installed on the side of the rotating shaft 39 away from the motor 38. The power of the motor 38 is transmitted to the conveying shaft 43 through the belt drive. This transmission method can achieve effective power transmission to a certain extent, so that the conveying shaft 43 can stably obtain power, thereby driving the spiral blades 44 to rotate, which improves the conveying efficiency of materials in the guide bin 41. The spiral blades 44 are sleeved inside the guide bin 41. When the conveying shaft 43 rotates, the spiral blades 44 will generate a pushing and stirring effect on the materials in the guide bin 41. On the one hand, the rotation of the spiral blades 44 can push the materials from one end of the guide bin 41 to the other end to realize the continuous conveying of materials. On the other hand, the stirring effect can prevent the materials from being blocked and accumulated in the guide bin 41, so that the materials can flow smoothly, further improving the efficiency and reliability of material conveying.

[0038] In one embodiment, the width of the feed hopper 41 gradually decreases towards the side closer to the discharge box 42.

[0039] With this design, the width of the guide bin 41 gradually decreases, making the channel for materials within the guide bin 41 gradually narrower. According to the principles of fluid mechanics, under the condition of a constant material flow rate, the narrowing of the channel will lead to an increase in the material flow velocity. The material can flow faster towards the lower material box 42 within the guide bin 41, reducing the residence time of the material within the guide bin 41 and improving the efficiency of material conveying.
