Description

Technical area

[0001] The present utility model relates to the technical field of bucket wheel loaders, specifically to a bucket wheel loader. State of the art

[0002] The bucket wheel loader is a highly efficient device for continuous loading and unloading of bulk materials in modern industry. It is currently widely used in ports, docks, metallurgy, cement plants, steel mills, coking plants, coal depots, power plants, and other bulk material storage facilities (ore, coal, coke, sand, and gravel) for stacking and unloading operations.

[0003] In the current use of the bucket wheel loader, especially in the transportation and loading of cement, sand and gravel, when the materials transported by the large bucket wheel arm are transported to the telescopic large arm, material splashes occur, especially for finer materials such as cement, sand and gravel, which causes environmental pollution and adheres to the frame of the bucket wheel loader, affecting the work of the bucket wheel loader. Content of the utility model

[0004] The aim of the present utility model is to provide a bucket wheel loader to solve the problems mentioned in the above background technology.

[0005] In order to achieve the above object, the present utility model offers the following technical solutions: a bucket wheel loader comprises a carriage frame of the bucket wheel loader, a travel drive system mounted on the bottom of the carriage frame of the bucket wheel loader, and a drive system, wherein a large bucket wheel arm and a bucket wheel are mounted on the carriage frame of the bucket wheel loader, the bucket wheel is mounted on the end of the large bucket wheel arm remote from the carriage frame of the bucket wheel loader, and a reservoir is arranged between the bucket wheel and the large bucket wheel arm, and a main oil pressure cylinder is arranged between the large bucket wheel arm and the carriage frame of the bucket wheel loader; a telescopic large arm is mounted on the carriage frame of the bucket wheel loader, a conveyor belt and an intermediate storage are arranged on the telescopic large arm, and the intermediate storage is located directly below the end of the large bucket wheel arm; and a filling opening is provided at the upper part of the intermediate storage area, and vertical plates directed vertically downwards are arranged at the filling opening, an outlet opening is provided at the side wall of the intermediate storage area, and one of the ends of the conveyor belt is located exactly inside the intermediate storage area.

Examples of implementation

[0013] In the following, the technical solutions in the embodiments of the present utility model are described clearly and completely with reference to the figures in the embodiments of the present utility model. Obviously, the described embodiments represent only a part of the embodiments of the present utility model and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by a person skilled in the art without creative effort fall within the scope of protection of the present utility model.

[0014] When referring to the Fig. 1-2, this embodiment provides a bucket wheel loader including a carriage frame of the bucket wheel loader 6, a travel drive system 7 mounted on the bottom of the carriage frame of the bucket wheel loader 6, and a large bucket wheel arm 2 and a telescopic large arm 8. The travel drive system 7 is a crawler belt travel system and is similar to the system of an excavator. A double-sided meshing structure of gears and gear rings is applied between the travel drive system 7 and the carriage frame of the bucket wheel loader 6. This allows both the large bucket wheel arm 2 to be deflected relative to the crawler belt in the travel drive system 7, and the telescopic large arm 8 to be deflected relative to the crawler belt in the travel drive system 7. Furthermore, the large bucket wheel arm 2 and the telescopic large arm 8 can be deflected relative to the crawler belt in the travel drive system 7 at the same time.The relative rotation angle is 360°, allowing the bucket wheel to be more flexible in use and suitable for various working environments. A drive system 9 is also arranged on the carriage frame of the bucket wheel loader 6. The drive system can power the angle adjustment of the large bucket wheel arm 2 and the telescopic large arm 8 on the carriage frame of the bucket wheel loader 6, as well as the conveyor belt, and is identical to the existing drive system.

[0015] A large bucket wheel arm 2 and a bucket wheel 3 are mounted on the carriage frame of the bucket wheel loader 6. The bucket wheel 3 is mounted on the end of the large bucket wheel arm 2 remote from the carriage frame of the bucket wheel loader 6, and a collecting container 10 is also arranged between the bucket wheel 3 and the large bucket wheel arm 2.

[0016] A telescopic large arm 8 is also mounted on the carriage frame of the bucket wheel loader 6, and a conveyor belt 4 and an intermediate storage 1 are also arranged on the telescopic large arm 8. The intermediate storage 1 is located just below the end of the large bucket wheel arm 2. The bucket wheel 3 rotates and loads raw materials from the ground into the bucket wheel 3. When the bucket wheel 3 rotates to the tip, the raw materials from the bucket wheel 3 enter the storage hopper 10. The raw materials enter the intermediate storage 1 via the conveyor belt in the large bucket wheel arm 2 and are transported from the intermediate storage 1 to the final storage point via the telescopic conveyor belt 4 in the telescopic large arm 8, thus realizing the relocation and stacking process of the raw materials.

[0017] A main oil pressure cylinder 102 is also arranged between the large bucket wheel arm 2 and the carriage frame of the bucket wheel loader 6. By controlling the extension and contraction of the main oil pressure cylinder 102, the angle of the large bucket wheel arm 2 can be adjusted, so that the height of the bucket wheel 3 above the ground can be controlled and the collection of raw materials can be ensured.

[0018] In this embodiment, the bucket wheel 3 can be arranged either on one side or symmetrically in two along the large bucket wheel arm 2, which facilitates the collection of raw materials.

[0019] During the transport of raw materials, especially with some powdery bulk materials such as sand, coal dust, and others, powder ash splashes may occur as the raw materials fall from the large bucket wheel arm 2 into the intermediate storage area 1. This pollutes both the environment and the machine.

[0020] Therefore, a filling opening 11 is provided at the upper part of the intermediate storage facility 1, and vertical plates 14 are arranged at the filling opening 11, which are directed vertically downwards. The vertical plates 14 extend downwards. An outlet opening 12 is provided at the side wall of the intermediate storage facility 1, and one of the ends of the conveyor belt 4 extends through the outlet opening 12 and is located exactly inside the intermediate storage facility 1. The raw materials fall directly onto the conveyor belt 4 in the intermediate storage facility 1. When powdery bulk materials enter the intermediate storage facility 1 via the filling opening 11, the bulk materials pass through the filling opening into the interior of the intermediate storage facility 1. The dust particles created by the falling powdery bulk materials are swirled obliquely upwards, so that they are completely enclosed in the interior of the intermediate storage facility 1 and are not swirled outwards, as in the Fig. 3-4. Compared with an existing intermediate storage facility with a fully open top or a structure with only one opening at the top, environmental pollution by powdery bulk materials and machine pollution can be completely avoided, and the application performance is better.

[0021] In this embodiment, the upper end of the intermediate storage facility 1 is arranged as an inclined structure. On the one hand, the inclined structure makes the area at the upper part of the intermediate storage facility 1 larger. When the amount of bulk materials transported by the large bucket wheel arm 2 is different and the amount of bulk materials is relatively large, the bulk materials can land on the inclined surface and have a buffering effect. And due to the arrangement of the inclined surface, when the bulk materials contact the inclined surface, no large impact is generated (the impact force is relatively small), so that excessive flying dust and powder are not generated. Compared with a single-plane arrangement, the inclined structure has a better effect.

[0022] A pusher bucket 5 is also mounted on the propulsion drive system 7. The pusher bucket 5 can push the scattered bulk materials into a pile and facilitate the collection of the bulk materials.

[0023] In addition, an automatic control system is also installed inside the carriage frame of the bucket wheel loader 6. It is possible to set programs and have the bucket wheel loader operate automatically. This process can only perform the work of raw material intake, such as the rotational speed of the bucket wheel 3, the extension and contraction angle of the large bucket wheel arm 2, and the oscillation speed, among other things. This control system is similar to the principle of fully automatic lathes. Alternatively, the carriage frame of the bucket wheel loader 6 has a fixed installation of receivers of the automatic control system, for example, it can be a Bluetooth receiver or a receiver in the local area network. It is possible to set programs and have the bucket wheel loader operate automatically, while also implementing remote control.

[0024] Since the raw materials land on the conveyor belt 4 in the intermediate storage 1 and there is an irregular fall of the raw materials on the conveyor belt 4 and the raw materials are also loose, it can inevitably occur that the raw materials fall from the conveyor belt 4 during the transport of the raw materials by the conveyor belt 4. Therefore, in a further embodiment, as shown in the Fig.5-6, the outlet opening 12 is designed as an isosceles trapezoidal structure, and a pressure support 13 is mounted on the side wall of the outlet opening 12. A rotary axis is mounted in the middle of the upper and lower ends of the pressure support 13, and holes for installing the rotary axis are drilled on the side wall of the outlet opening 12. The pressure support 13 is rotatably mounted on the side wall of the outlet opening 12. When the bulk materials on the conveyor belt 4 pass through the outlet opening 12, the pressure support 13 will compress the bulk materials on the conveyor belt 4, so that the bulk materials are more compact with each other. Falling of the bulk materials can be avoided during transportation. And when the pressure support 13 comes into contact with the bulk materials on the conveyor belt 4, the pressure support 13 will rotate under the influence of the bulk materials, so that the friction between the pressure support 13 and the bulk materials is reduced.Compared with a direct arrangement of an inclined pressure plate, the inclined pressure plate can only play the role of scraping, but the bulk materials may still fall. The rotation of the pressure support 13 can prevent the bulk materials from falling due to the resistance or friction of the pressure support 13.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by one of ordinary skill in the art that various variations, modifications, substitutions, and variants may be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is determined by the appended claims and their equivalents.
