Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a coal belt conveyor capable of realizing the movement of the machine tail. Background Technique

[0002] When transporting coal, in order to avoid coal dropping, the upper side part of the conveyor belt of the coal conveyor is formed into a concave structure by setting up inclined rollers distributed at intervals on both sides of the belt conveyor, and both sides of the conveyor belt pass through the inclined rollers.

[0003] According to the requirements of the usage situation, the coal belt conveyor needs different effective conveying lengths. At this time, the machine tail needs to be movable to adjust the overall conveying length. Publication (Announcement) No.: CN218056968U, a new type of telescopic belt conveyor with adjustable length, adjusts the overall length by moving the position of the belt roller at one end. However, the above method of only moving the belt roller will cause the instability of the concave structure. Therefore, this solution provides a coal belt conveyor capable of realizing the movement of the machine tail, which will not affect the stable formation of the concave structure on the conveyor belt while adjusting the overall length. Summary of the Utility Model

[0004] The utility model aims to solve at least the problem of how to stably maintain the concave structure of the conveyor belt under the adjustment of the overall length of the belt conveyor in the prior art.

[0005] This solution provides a coal belt conveyor capable of realizing the movement of the machine tail, which is achieved by the following specific technical means: including a frame and a conveyor belt. The frame is composed of a fixed frame and multiple groups of movable frames. A power belt roller is rotatably installed on the fixed frame. Multiple groups of movable frames are arranged in sequence at the tail of the fixed frame. A driven belt roller is rotatably installed on the last group of movable frames. At the same time, inclined rollers are rotatably installed on both sides of the other groups of movable frames and the rear part of the fixed frame located behind the power belt roller. The conveyor belt is sleeved between the power belt roller and the driven belt roller. At the same time, the upper side part of the conveyor belt passes through multiple groups of inclined rollers to form an upward concave morphological structure of the upper side part of the conveyor belt.

[0006] Preferred Technical Solution 1: Between adjacent two groups of movable frames, and between the frontmost group of movable frames and the tail end of the fixed frame, they are connected by telescopic frames. At the same time, the ends of adjacent two groups of telescopic frames are hinged to realize the linkage between multiple groups of telescopic frames.

[0007] Preferred Technical Solution 2: Balancing mechanisms are installed on the bottom sides of multiple groups of movable frames located in the middle. The balancing mechanisms are used to maintain the tension state of the conveyor belt when the overall length of the belt conveyor is adjusted.

[0008] Optimal Technical Solution 3: The balance mechanism includes a connecting arm rotatably arranged in the middle on the middle movable frame. Tension rollers are rotatably installed at both ends of the connecting arm, and the conveyor belt bypasses the two groups of tension rollers in an S shape.

[0009] Optimal Technical Solution 4: Movable wheels are installed on the bottom side of the movable frame.

[0010] Adopting the above structure enables this solution to have the following beneficial effects:

[0011] While the tail end can move back and forth according to the situation, the linkage between multiple movable frames also ensures that the inclined rollers have sufficient inclined lifting effect on the upper side of the conveyor belt, avoiding the problem that the concave surface at the top of the conveyor belt cannot be stably maintained easily when only moving the driven belt roller.

[0019] Please refer to Figures 1-4, a coal belt conveyor capable of moving the machine tail, comprising a frame 1 and a conveyor belt 2. The frame 1 is composed of a fixed frame 11 and multiple groups of movable frames 12. A power belt roller 4 is rotatably installed on the fixed frame 11, and a second motor 3 connected to the driving belt roller is fixed on the fixed frame 11. The second motor 3 can drive the power belt roller 4 to rotate. Multiple groups of movable frames 12 are arranged in sequence at the tail of the fixed frame 11. Movable wheels 10 are installed on the bottom sides of the movable frames 12 to facilitate the movement of the tail end. A driven belt roller 5 is rotatably installed on the last group of movable frames 12 at the tail end. At the same time, inclined rollers 6 are rotatably installed on both sides of other groups of movable frames 12 and on the rear side part of the fixed frame 11 located behind the power belt roller 4. The conveyor belt 2 is sleeved between the power belt roller 4 and the driven belt roller 5. At the same time, the upper side part of the conveyor belt 2 passes through multiple groups of inclined rollers 6, forming an upward concave morphological structure on the upper side part of the conveyor belt 2. When changing the overall length of the belt conveyor, the inclined rollers 6 can always maintain the inclined lifting effect on the upper side of the conveyor belt 2 by moving the distance between multiple groups of movable frames 12. The adjacent two groups of movable frames 12, as well as between the foremost group of movable frames 12 and the tail end of the fixed frame 11, are connected by a telescopic frame 7; balance mechanisms 9 are installed on the bottom sides of multiple groups of movable frames 12 located in the middle. The balance mechanism 9 is used to keep the conveyor belt 2 in a tensioned state when the overall length of the belt conveyor is adjusted.

[0020] Please refer to Figure 1 and Figure 3 , a coal belt conveyor capable of moving the machine tail, the telescopic frame 7 includes a rod one 71 and a rod two 72. Convex shafts 73 are fixed on the movable frames 12 and on the side edges of the tail ends of the fixed frame 11. The rod one 71 and the rod two 72 are rotatably sleeved on a group of convex shafts 73 and are in a crossed state. The two ends of the rod one 71 in a group of telescopic frames 7 are respectively hinged to the ends of the rod two 72 in the front and rear two groups of telescopic frames 7. At the same time, the two ends of the rod two 72 in the telescopic frame 7 are respectively hinged to the ends of the rod one 71 in the front and rear two groups of telescopic frames 7 to realize the linkage between multiple groups of telescopic frames 7. A push rod 8 is hingedly installed on a group of movable frames 12. The telescopic end of the push rod 8 is hingedly connected to the rod one 71 located on this group of movable frames 12. By controlling the telescopic movement of the push rod 8, the rod one 71 rotates around the convex shaft 73, thereby simultaneously controlling the telescopic movement of multiple groups of telescopic frames 7 and realizing the regulation of the distance between multiple groups of movable frames 12.

[0021] Please refer to Figure 2 and Figure 4, a coal belt conveyor capable of realizing the movement of the tail end. The balance mechanism 9 includes a connecting arm 91 rotatably arranged in the middle on the middle movable frame 12. A plurality of groups of movable frames 12 located in the middle are each fixed with a first motor 93. The output shaft of the first motor 93 is fixedly connected to the middle of the connecting arm 91 to drive the connecting arm 91 to rotate. Tension rollers 92 are rotatably installed at both ends of the connecting arm 91. The conveyor belt 2 sequentially bypasses the two tension rollers 92 in an S shape. When the overall length of the belt conveyor is adjusted, the rotation angle of the connecting arm 91 also changes accordingly, that is, when the overall length of the belt conveyor is shortened, the connecting arm 91 tends to be vertical, and when the overall length of the belt conveyor is lengthened, the connecting arm 91 tends to be horizontal.

[0022] Please refer to Figure 1 , a coal belt conveyor capable of realizing the movement of the tail end. A controller is arranged in the fixed frame 11. The controller is electrically connected to the push rod 8, the first motor 93 and the second motor 3 to control the working states of the push rod 8, the first motor 93 and the second motor 3, so as to realize the control of the overall length of the belt conveyor and the tension of the conveyor belt 2.
