Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to an anti-slip structure for a conveyor belt of an excavator loader. Background Art

[0002] Backhoe loaders are mechanical equipment that are mainly used for collecting gravel and soil in narrow cave mining operations such as phosphate ore, iron ore, copper ore, gold ore, silver ore, lead and zinc ore, and coal mine tunnels, as well as various mines, hydropower, and tunnel projects. The collected materials are then transported and loaded onto trucks via conveyor belts.

When loose, it will cause the material to fall off and the conveyor belt to fall off, which not only increases the time of conveying materials, but also increases the danger of the processing environment. For this reason, we propose an anti-slip structure for the conveyor belt of an excavator loader. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a conveyor belt anti-slip structure for an excavator loader, comprising a support seat 15, the support seat 15 is fixedly connected to one end of a mounting frame 5, such as Figure 1 As shown, in order to facilitate the movement of the device, a first bracket 2 and a second bracket 7 are respectively connected to the two ends of the mounting frame 5, and rollers 4 are rotatably connected to the bottom of the first bracket 2 and the second bracket 7. A tensioning roller 12 is connected between the support seat 15 and the mounting frame 5, and an active roller 8 is rotatably connected to the other end of the mounting frame 5. A driving motor 9 is fixedly connected to one end of the active roller 8, and a conveyor belt 1 is connected between the tensioning roller 12 and the active roller 8. A plurality of supporting rollers 6 for supporting the conveyor belt 1 are rotatably connected to the mounting frame 5. The driving motor 9 drives the conveyor belt 1 to rotate for transportation operations, and under the support of the supporting rollers 6, the overall supporting capacity of the conveyor belt 1 is improved.

[0021] like Figure 2 As shown, in order to adjust the tension between the tension roller 12 and the conveyor belt 1, a hydraulic telescopic rod 23 is fixedly connected to the support seat 15, and a buffer mechanism is connected to the end of the hydraulic telescopic rod 23. A second U-shaped frame 17 is connected to the other end of the buffer mechanism, and a pressure sensor 20 is connected between the second U-shaped frame 17 and the hydraulic telescopic rod 23. The buffer mechanism includes a first connecting plate 21 and a second connecting plate 24. The first connecting plate 21 is against the pressure sensor 20. When actually installed and used, as shown in FIG. Figure 3 As shown, the pressure sensor 20 is connected to the second U-shaped frame 17 via a screw rod 18 and is fixed via a nut 19 .

[0022] like Figure 3 As shown, the second connecting plate 24 is connected to the end of the hydraulic telescopic rod 23, and the second U-shaped frame 17 is symmetrically connected with the second guide rod 16, which passes through the first connecting plate 21 and the second connecting plate 24 in sequence. A return spring 22 is coaxially connected to the second guide rod 16 located between the first connecting plate 21 and the second connecting plate 24, and the end of the second guide rod 16 is connected to a limiting plate 25. When the hydraulic telescopic rod 23 pushes the second connecting plate 24 to move, the second connecting plate 24 generates pressure on the return spring 22, and under the elastic force of the return spring 22, the pressure can be buffered.

[0023] like Figure 3As shown, the tensioning roller 12 is connected to the first U-shaped frame 13 through the connecting shaft 11, and in order to ensure the stable sliding of the tensioning roller 12, a slide groove 3 is symmetrically opened on the installation frame 5, and the end of the connecting shaft 11 is arranged through the slide groove 3. When the tensioning roller 12 moves, it can drive the connecting shaft 11 to slide in the slide groove 3 and play a guiding role. The end of the second U-shaped frame 17 is fastened to the outer wall of the first U-shaped frame 13. At the same time, in order to improve the sliding stability of the hydraulic telescopic rod 23, the first guide rod 14 is symmetrically connected along the hydraulic telescopic rod 23 on the outer wall of the first U-shaped frame 13, and the guide seat 10 matched with the first guide rod 14 is connected on the inner wall of the installation frame 5.

[0024] To sum up, when the conveyor belt anti-slip structure of the excavator loader is in use, the pressure sensor 20, the hydraulic telescopic rod 23 and the drive motor 9 are connected to the control switch through wires. When the tension of the conveyor belt 1 needs to be adjusted, the hydraulic telescopic rod 23 is controlled to telescopically move. The moving hydraulic telescopic rod 23 pushes the tensioning roller 12 and the first U-shaped frame 13 to move, so as to adjust the distance between the tensioning roller 12 and the active roller 8, and thus quickly adjust the tension of the conveyor belt 1, thereby effectively preventing the conveyor belt 1 from falling off, thereby ensuring the normal use of the device.
