[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a technical solution for a telescopic belt conveyor:

[0024] Example:

[0025] like Figure 1-4As shown, it includes a base frame 1, a support rod 3 is connected to the top of the base frame 1, a fixed rod 4 is connected to the top of the support rod 3, a first rotating rod 5 is connected between the two fixed rods 4, a motor 6 is provided on one side of the fixed rod 4, a slide rail 7 is provided on each adjacent side of the two fixed rods 4, a movable rod 11 is movably provided on one side of the slide rail 7, a second rotating rod 12 is provided between the two movable rods 11, a connecting frame 13 is connected to one side of the movable rod 11, a connecting rod 14 is connected to the top of the connecting frame 13, a cylinder 15 is provided on the side of the fixed rod 4 opposite to the motor 6, a collar 16 is connected to the output end of the cylinder 15, a limiting frame 17 is connected to the bottom of the slide rail 7, a slide groove 18 is provided through the inner cavity of the limiting frame 17, a slide groove 18 is provided in the inner cavity of the slide groove 18, a slide rod 19 is connected between the two slide rods 19, and a third rotating rod 26 is connected between the two slide rods 19, and a belt 27 is commonly sleeved on the outer rings of the first rotating rod 5, the second rotating rod 12 and the third rotating rod 26.

[0026] The collar 16 is movably sleeved on the outer ring of the connecting rod 14 .

[0027] Among them, one side of the movable rod 11 is rotatably connected to the roller 8, the outer ring of the roller 8 is provided with a limiting groove 10, and the inner wall of the slide rail 7 is provided with a limiting rod 9, and the diameter of the limiting rod 9 is consistent with the inner diameter of the limiting groove 10.

[0028] Among them, a fixed block 21 is connected to one side of the limit frame 17, a screw 22 is connected between the two fixed blocks 21, the outer ring of the screw 22 is threadedly connected to the adjusting nut 23, and one end of the slide rod 19 is connected to a sleeve 20, which is movably sleeved on the outer ring of the screw 22. The sleeve 20 is located below the adjusting nut 23, and trays 24 are provided below the adjusting nut 23 and above the sleeve 20, and a spring 25 is provided between the two trays 24.

[0029] The telescopic principle of the device in this embodiment is as follows: when in use, the ring 16 is pushed by the cylinder 15, and then the connecting frame 13 is driven to move through the connecting rod 14. At this time, the connecting frame 13 can drive the movable rod 11 to move, and the distance between the first rotating rod 5 and the second rotating rod 12 can be adjusted, thereby achieving the purpose of extending the transmission distance of the belt 27. At this time, the belt 27 pulls up the third rotating rod 26 by itself and compresses the spring 25 to provide an extension distance. When the cylinder 15 retracts, the pressure of the belt 27 on the spring 25 gradually weakens. At this time, the third rotating rod 26 moves downward under the influence of the pressure of the spring 25, thereby tightening the belt 27 to prevent the belt 27 from loosening. Therefore, the purpose of extending and retracting the belt conveyor can be achieved with only one cylinder 15, which greatly reduces the cost of using the device, and has a simple structure, convenient maintenance and installation, and is suitable for popularization and use.

[0030] By adjusting the nut 23, the preload of the spring 25 can be adjusted, thereby maintaining the appropriate tension of the belt 27, thereby improving the practicality of the device;

[0031] By setting the roller 8, the friction between the movable rod 11 and the slide rail 7 during movement can be reduced, thereby facilitating the movement of the movable rod 11, reducing the burden on the oil cylinder 15, and improving the service life of the structure.

[0032] The outer rings of the first rotating rod 5 and the third rotating rod 26 are both sleeved with limiting rings 28 , and the belt 27 is located between the two limiting rings 28 .

[0033] In this embodiment, the limiting ring 28 plays a limiting role to prevent the belt 27 from lateral displacement during adjustment or use, thereby improving the stability of the device.

[0034] The bottom of the base frame 1 is rectangular and has a plurality of universal wheels 2 distributed thereon.

[0035] In this embodiment, the universal wheels 2 can facilitate the movement of the entire device, making the use of the device more convenient.
