[0002] Belt conveyors, also known as belt conveyors, are a type of transportation equipment widely used in industry. They utilize a belt as a load-bearing and traction member, pulling the conveyor belt and materials through friction between a drive roller and the belt. Belt conveyors offer high conveying capacity, smooth operation, low noise, and simple maintenance. They are suitable for conveying a variety of materials, including solids, granular materials, mixtures, and fluids. Furthermore, they are energy-efficient, environmentally friendly, and have a low breakage rate for conveyed materials, making them essential equipment for modern assembly line production. Belt conveyors play a vital role in industries such as coal, metal mining, building materials, chemicals, electricity, and grain, significantly improving production efficiency and transportation safety.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for an adjustable belt conveyor support bed buffer device, including a support bed body 1, support legs 2 are fixedly installed at the four corners of the bottom of the support bed body 1, drive rollers 4 are movably installed in the support bed body 1, and a conveyor belt 3 is provided between the drive rollers 4. A buffer mechanism 5 is provided at one end of the support bed body 1, and a drive mechanism 6 is provided on the positioning bracket 503. Through the coordinated use of the buffer mechanism 5 and the drive mechanism 6, the impact on the conveyor belt 3 can be reduced and the service life of the conveyor belt 3 can be extended.

[0022] like Figure 2 and Figure 3As shown, the buffer mechanism 5 includes a positioning bracket 503 fixedly mounted on the support bed body 1, a movable hole 505 is opened on the positioning bracket 503, a movable shaft 502 is movably installed in the movable hole 505, a buffer slide 501 is fixedly installed on the movable shaft 502, and positioning legs 506 are provided on the positioning bracket 503 and the buffer slide 501, a return spring 507 is provided between the positioning legs 506, a mounting screw hole 504 is opened on the positioning bracket 503, and a bolt is provided in the mounting screw hole 504, the positioning bracket 503 is fixed to the support bed body 1 by the bolt, one end of the return spring 507 is connected to the positioning bracket 503 through the positioning leg 506, and the other end of the return spring 507 is connected to the buffer slide 501 through the positioning leg 506.

[0023] Specifically, the input gear 607 can be driven to rotate by the driving motor 603. After the input gear 607 rotates, it will drive the reduction gear 606 to rotate. After the reduction gear 606 rotates, it will drive the half gear 602 to rotate. During the rotation process of the half gear 602, it will intermittently drive the driving gear 601 to rotate, thereby driving the buffer chute 501 to swing back and forth to unload.

[0024] like Figure 2 and Figure 4 As shown, the driving mechanism 6 includes a mechanism housing 604 fixedly mounted on the positioning bracket 503 and a driving gear 601 fixedly mounted on the movable shaft 502, a driving motor 603 is fixedly mounted on the mechanism housing 604, a half gear 602 is movably mounted in the mechanism housing 604, a reduction gear 606 is fixedly mounted on the half gear 602, an input gear 607 is fixedly mounted on the output end of the driving motor 603, and the input gear 607 is meshed with the reduction gear 606, a driving shaft 605 is provided on the half gear 602, and the half gear 602 is movably mounted in the mechanism housing 604 through the driving shaft 605, a notch is opened at the upper end of the mechanism housing 604, and a portion of the driving gear 601 extends into the mechanism housing 604 through the notch.

[0025] Specifically, after the movable shaft 502 rotates, it will drive the buffer chute 501 to tilt, so that the material on the buffer chute 501 will slowly roll down, and after the material on the buffer chute 501 has completely rolled down, the driving gear 601 will be separated from the half gear 602. After the driving gear 601 is separated from the half gear 602, the reset spring 507 will pull the buffer chute 501 to reset. After the buffer chute 501 is reset, the material will fall onto its surface again. By controlling the buffer chute 501 to swing back and forth, the material falling from a high place can be slowly rolled onto the conveyor belt 3, thereby reducing the impact on the conveyor belt 3 and extending the service life of the conveyor belt 3.

[0026] Working principle: When in use, the material will first fall onto the buffer chute 501. After the material falls onto the buffer chute 501, the drive motor 603 can be started. After starting the drive motor 603, it will drive the input gear 607 to rotate. After the input gear 607 rotates, it will drive the reduction gear 606 to rotate. After the reduction gear 606 rotates, it will drive the half gear 602 to rotate. The rotation process of the half gear 602 will intermittently drive the drive gear 601 to rotate. When the drive gear 601 rotates intermittently, it will drive the movable shaft 502 to rotate. After the movable shaft 502 rotates, it will drive the buffer chute 501 to tilt, so that the material on the buffer chute 501 slowly rolls onto the conveyor belt. 3, reducing the impact on the conveyor belt 3, extending the service life of the conveyor belt 3, and after the material on the buffer chute 501 completely rolls onto the conveyor belt 3, the driving gear 601 will be separated from the half gear 602. Since one end of the return spring 507 is connected to the positioning bracket 503 through the positioning support foot 506, and the other end of the return spring 507 is connected to the buffer chute 501 through the positioning support foot 506, the return spring 507 will pull the buffer chute 501 to reset after the driving gear 601 is separated from the half gear 602. After the buffer chute 501 is reset, the material will fall onto its surface again. Repeating the above actions can make the material falling from a high place slowly roll onto the conveyor belt 3.
