Description

Technical Field

[0001] The invention relates to a bucket elevator, in particular to an external bearing structure of a bucket elevator used for powder material transportation. Background Art

[0002] In the production industry, powdered raw materials are generally transported by bucket elevators. During the use of bucket elevators, powder materials accumulate at the bottom of the bucket elevator, and the powder enters the gap of the tail wheel bearing of the bucket elevator as the tail wheel rotates. Long-term use will cause bearing wear and failure. The bearing damage frequency is high, which greatly shortens the service life of the bearing. At the same time, since the bearing is inside the bucket elevator housing, it is not convenient to observe the bearing status during lubrication, resulting in difficult maintenance and long maintenance time. Secondly, since the bearing is inside the bucket elevator housing, it will be difficult and time-consuming to replace the bearing.

[0003] In view of the above-mentioned shortcomings of the existing structure, this solution proposes an external bearing structure of a bucket elevator for powder material transportation. Summary of the invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an external bearing structure of a bucket elevator for powder material transportation.

[0006] In the present invention, shaft through holes are provided on both side walls of the bucket lifting shell, the shaft through holes are elliptical, and the shaft extends through the shaft through holes to exit the outside of the bucket lifting shell.

[0007] In the present invention, the center points of the movable internal material baffle plate, the external adjustable material baffle plate and the tail wheel are concentric.

[0008] In the present invention, the movable internal material baffle plate, the external adjustable material baffle plate, the locking slide wire and the external bearing installed on both sides of the shaft body of the rotating shaft are all symmetrically arranged.

[0009] In the present invention, a fixed section matching the number and setting position of the movable built-in material baffle plate and the external adjustable material baffle plate is provided on the shaft body of the rotating shaft, and matching threads are provided on the surface of the fixed section and the inner wall of the center hole of the movable built-in material baffle plate and the external adjustable material baffle plate.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , an external bearing structure of a bucket elevator for powder transportation, comprising a bucket elevator shell 1 and a tail wheel 2; the tail wheel 2 is installed inside the bucket elevator shell 1; it also includes a movable built-in material baffle plate 3, an external adjustable material baffle plate 4, a locking slide 5 and an external bearing 6; the tail wheel 2 is installed inside the bucket elevator shell 1, and a rotating shaft 7 is connected to the center positions of both ends of the tail wheel 2, and the other end of the rotating shaft 7 extends to the outside of the bucket elevator shell 1; the movable built-in material baffle plate 3 is installed inside the bucket elevator shell 1 and on both sides of the shaft body of the rotating shaft 7; the external adjustable material baffle plate 4 is installed outside the bucket elevator shell 1 and on both sides of the shaft body of the rotating shaft 7; the locking slide 5 is installed on a side surface of the external adjustable material baffle plate 4 away from the bucket elevator shell 1, and the locking slide 5 is vertical to the external adjustable material baffle plate 4; the external bearing 6 is installed at both ends of the shaft body of the rotating shaft 7 and on the outside of the external adjustable material baffle plate 4.

[0025] In the present bearing structure, shaft through holes are provided on both side walls of the bucket lifting housing 1 , the shaft through holes are elliptical, and the shaft 7 extends through the shaft through holes to exit the outside of the bucket lifting housing 1 .

[0026] In this bearing structure, the movable internal baffle plate 3, the external adjustable baffle plate 4 and the center point of the tail wheel 2 are concentric. The movable internal baffle plate 3, the external adjustable baffle plate 4, the locking slide 5 and the external bearing 6 installed on both sides of the shaft body of the rotating shaft 7 are symmetrically arranged.

[0027] like Figure 4 As shown, a fixed section matching the number and setting position of the movable internal baffle plate 3 and the external adjustable baffle plate 4 is provided on the shaft body of the rotating shaft 7, and matching threads are provided on the surface of the fixed section and the inner wall of the center hole of the movable internal baffle plate 3 and the external adjustable baffle plate 4. The movable internal baffle plate 3 and the external adjustable baffle plate 4 can be removed from the rotating shaft 7.

[0028] like Figure 1 As shown, the diameters of the movable internal baffle plate 3 and the external adjustable baffle plate 4 are larger than the diameter of the tail wheel 2. The larger diameters of the movable internal baffle plate 3 and the external adjustable baffle plate 4 can better prevent powder from flying out of the bucket lifting housing 1 and entering the external bearing 6 to damage the external bearing 6.

[0029] In this bearing structure, the movable internal baffle plate 3 is arranged close to the inner walls on both sides of the bucket lifting housing 1; the external adjustable baffle plate 4 is arranged close to the outer walls on both sides of the bucket lifting housing 1. The distance between the movable internal baffle plate 3 and the external adjustable baffle plate 4 and the bucket lifting housing 1 is reduced as much as possible to effectively prevent the powder from floating out.

[0030] Embodiment: Compared with the existing bearing structure, the present bearing structure installs the external bearing 6 on the outside of the bucket elevator shell 1; during the process of conveying powder by the bucket elevator, the powder accumulates at the bottom of the bucket elevator, the external bearing 6 is installed on the outside of the bucket elevator shell 1, and a movable internal baffle plate 3 and an external adjustable baffle plate 4 are installed on the shaft body of the rotating shaft 7 between the external bearing 6 and the bucket elevator shell 1. When the bucket elevator is running, the movable internal baffle plate 3 and the external adjustable baffle plate 4 are used to block the powder from entering the gap of the external bearing 6; at the same time, the external adjustable baffle plate 4 is also used to adjust the deviation of the tail wheel, and the height of the tail wheel 2 is adjusted by the locking slide 5 on the external adjustable baffle plate 4. During the adjustment process, the movable internal baffle plate 3 moves synchronously with the tail wheel 2 to prevent powder from overflowing and thereby reduce damage to the external bearing 6.

[0031] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also includes other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical scheme.
