Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a telescopic belt conveyor. Background Technology

[0002] In the field of industrial production and material handling, belt conveyors are widely used as important continuous transportation equipment in various industries such as mining, metallurgy, chemical industry, building materials, and grain. They are used to transport materials in different forms, such as lumps, granules, and powders. Traditional belt conveyors have a relatively simple structure and are mostly fixed designs, which means that the conveyors occupy a lot of space even when they are not in use, making them inconvenient for storage or transportation. In addition, during the material transport process, the material falling on the belt will raise a lot of dust. This dust not only pollutes the working environment but also harms the health of operators. Long-term exposure may also cause occupational diseases such as respiratory diseases.

[0003] Therefore, we have designed a telescopic belt conveyor to solve the above problems. Utility Model Content

[0014] 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.

[0015] Example 1: Please refer to Figures 1-4This telescopic belt conveyor mainly consists of a belt support 1, a drive roller 4, a driven roller 8, a conveyor belt 12, a base 13, a drive mechanism 14, a trough support 15, a funnel trough 16, a dust collection hood 17, and a dust removal structure 18. The front half of the belt support 1 is inclined upwards, and the rear half is horizontal. The drive roller 4 is rotatably mounted on the rear end of the horizontal part via a bearing seat. The bottom of the inclined part is fixed with a first U-shaped frame 5. A sliding groove is provided on the inner side of the inclined part, and a telescopic frame 7 is slidably mounted thereon. The front end of the telescopic frame 7 is rotatably mounted with a driven roller 8 via a bearing seat. The bottom of the telescopic frame 7 is fixed with a second U-shaped frame 10. The first U-shaped frame 5 and the second U-shaped frame 10 are connected by a hydraulic cylinder 11, which is connected to an external hydraulic control system. The hydraulic control system is connected to an external control console. The conveyor belt 12 is set between the drive roller 4 and the driven roller 8. Through the hydraulic cylinder 11, the telescopic frame 7 can be driven to extend and retract at the front end of the belt support 1. When the telescopic frame 7 extends, it not only tightens the conveyor belt 12 to prevent slippage during material conveying, but also allows the conveyor belt to extend and retract. The conveyor as a whole has a higher upward height to accommodate higher material conveying. The retractable lifting frame 7 reduces the space occupied by the conveyor, making it easier to store and transport. Guide wheels 2 are rotatably installed on both sides of the top of the bend of the belt support 1 via bearing seats. The guide wheels 2 press against the top of the conveyor belt 12. Guide rollers 3 are rotatably installed at the bottom of the bend, pressing against the bottom of the inner side of the conveyor belt 12. Multiple equally spaced limiting rollers 6 are rotatably installed at the bottom of the belt support 1, supporting the bottom of the conveyor belt 12. Multiple equally spaced trough rollers 9 are rotatably installed at the top of the belt support 1. Trough rollers 9 are also rotatably installed at the top of the lifting frame 7 near the front end, supporting the top of the inner side of the conveyor belt 12. Through the combined action of the guide wheels 2, guide rollers 3, limiting rollers 6, and trough rollers 9, the conveyor belt 12 can be guided to fit against the belt support 1. In addition, the limiting rollers 6 can also support the conveyor belt 12 when the lifting frame 7 is retracted, preventing the conveyor belt 12 from dragging on the ground when it becomes slack.

[0016] The belt support 1 is mounted on the base 13. The drive mechanism 14 is mounted on the side of the base 13. The drive mechanism 14 consists of a reducer and a motor. The reducer is mounted on the base 13 and its output shaft is connected to the shaft of the drive roller 4. The motor is mounted on the reducer and its output shaft is connected to the input shaft of the reducer. The motor is connected to an external control console. When using the conveyor, the motor is started, and the drive roller 4 can be driven to rotate through the reducer, which in turn drives the conveyor belt 12 to rotate. The top of the base 13 is fixed with a trough support 15. A funnel trough 16 is mounted on the trough support 15. The bottom outlet of the funnel trough 16 is located directly above the conveyor belt 12 on the horizontal part of the belt support 1. The material to be conveyed is put into the funnel trough 16, and the material can be fed onto the conveyor belt 12 through the funnel trough 16.

[0017] A dust collection hood 17 is installed on the side of the material trough support 15. The dust collection hood 17 is connected to a dust removal structure 18 via a pipe. The dust removal structure 18 includes a barrel 1801, a vacuum pump 1802, a filter screen 1803, and an air hammer 1804. The barrel 1801 is located next to the base 13. The vacuum pump 1802 is connected to an external control console and is mounted on the barrel 1801. Its air inlet is connected to the top of the barrel 1801 via a pipe. The filter screen 1803 is installed inside the barrel 1801, and the air hammer 1804 is installed on the outside of the barrel 1801. A dust inlet is opened on the side of the barrel 1801 below the filter screen 1803. The dust inlet is connected to the dust collection hood 17 via a pipe. The bottom of the hood 17 is funnel-shaped, and the dust inlet... A gate is installed at the outlet. When the conveyor is working, the vacuum pump 1802 is started. The vacuum pump 1802 can expel the air inside the barrel 1801, making the inside of the barrel 1801 a negative pressure state. When the material falls onto the conveyor belt 12 and raises dust, this dust will enter the barrel 1801 through the dust suction hood 17 under the action of negative pressure. The filter screen 1803 can keep the dust inside the barrel 1801. After the work is completed, the gate at the bottom outlet of the barrel 1801 is opened to discharge the dust inside the barrel 1801. During the dust discharge, the air hammer 1804 is started to strike the barrel 1801, which can shake off the dust attached to the inner wall of the barrel 1801 and the filter screen 1803 through vibration.

[0018] Operating Procedure: When using this telescopic belt conveyor, start the hydraulic cylinder 11, which drives the extension frame 7 to extend until the conveyor belt 12 is taut. Then, start the motor of the drive mechanism 14, which drives the drive roller 4 to rotate through the reducer, thereby driving the conveyor belt 12 to move. The material to be conveyed is put into the funnel trough 16, and the material falls from the funnel trough 16 onto the conveyor belt 12 and is conveyed. During the material conveying, start the vacuum pump 1802, which discharges the air inside the barrel 1801, making the inside of the barrel 1801 under negative pressure. The dust generated during the conveying process is sucked into the dust removal structure 18 by the dust suction hood 17 under negative pressure, and collected in the barrel 1801 after being filtered by the filter screen 1803. After the material conveying is completed, open the gate at the bottom outlet of the barrel 1801 to discharge the dust inside the barrel 1801. During the dust discharge, the barrel 1801 and the filter screen 1803 can be vibrated by the air hammer 1804 to help with the dust discharge.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
