[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Embodiment 1

[0023] The utility model provides a double-track bucket wheel loader, as Figures 1 to 6 shown, which includes a bucket wheel loader 1. One end of the bucket wheel loader 1 is fixedly installed with a cantilever belt conveyor 2. Symmetrically and movably connected inside the cantilever belt conveyor 2 are connecting arms 16. One end of the connecting arm 16 is fixedly connected with a hopper 3. The bottom end of the hopper 3 is fixedly connected with a support platform 8. Both ends of the support platform 8 are fixedly connected with support frames 5. On both sides of the bottom end of the support frame 5 are fixedly installed crawler wheels 4. On both sides of the bottom end of the support platform 8 are fixedly installed belt conveying devices 7. At the bottom end of the support platform 8 is fixedly installed a scraper 6. Inside the belt conveying device 7 is fixedly installed a belt scale 9.

[0024] As Figure 1 and Figure 6 shown, between two fixing blocks 11 and at the bottom end position of the first bolt 22 is fixedly connected with a fixing rod 13. In the middle of the top end of the fixing rod 13 is provided a fixing hole 14. One end of the connecting arm 16 is installed with a U-shaped block 17. Inside the U-shaped block 17 is movably connected with a second bolt 21. On the outer surface of the second bolt 21 and at the top end position of the U-shaped block 17 is threadedly connected with a second nut 20. Through the cooperation of the second bolt 21 and the second nut 20, the up-and-down swing of the connecting arm 16 is effectively prevented, and the stability of the overall structure is improved.

[0025] As Figure 1 and Figure 4 shown, at the bottom of one end of the cantilever belt conveyor 2 is fixedly connected with a fixing plate 10. On both sides of the bottom end of the fixing plate 10 are fixedly connected with two fixing blocks 11. Through both of the two fixing blocks 11 is movably connected a first bolt 22 in a penetrating manner. The first bolt 22 penetrates through the inside of the connecting arm 16 and is movably connected with the connecting arm 16. On the outer surface of the first bolt 22 and at one end position of the connecting arm 16 is threadedly connected with a first nut 18. Through the cooperation of the first bolt 22 and the first nut 18, the connection stability between the connecting arm 16 and the fixing plate 10 is enhanced, ensuring the normal operation of material transportation.

[0026] As Figure 1 and Figure 2 shown, the horizontal height of the bottom of the scraper 6 is different from the horizontal height of the belt conveying device 7. The scraper 6 at different heights can more effectively distribute the materials evenly on the belt, realizing the precise loading of the materials.

[0027] As Figure 1 and Figure 2 shown, the shape of the hopper 3 is conical. The conical design reduces the possibility of materials piling up in corners or edges, reducing the risk of blockage.

[0028] As Figure 1 and Figure 5As shown, the diameter of the fixed rod 13 is the same as the inner diameter of the U-shaped block 17, and the diameters of the fixed rod 13 and the U-shaped block 17 are the same, ensuring a tight fit between the two and improving the structural stability.

[0029] Working principle: One end of the connecting arm 16 is clamped outside the fixed block 11, then the U-shaped block 17 is used to clamp the fixed rod 13, then the second bolt 21 passes through the U-shaped block 17 and the fixing hole 14, and then the second nut 20 is tightened to effectively prevent the up-and-down swing of the connecting arm 16 and improve the stability of the overall structure. Then, the first bolt 22 passes through the connecting arm 16 and the fixed block 11, and then the first nut 18 is tightened to fix the fixing plate 10 and the connecting arm 16, ensuring that the device is stably maintained in the set position and guaranteeing the normal operation of the device.

[0030] Start the bucket wheel loader 1, and the material will be driven forward by the cantilever belt conveyor 2 and sent into the hopper 3. It just falls above the belt conveyor device 7 from the hopper 3. The material will be leveled by the scraper 6, and then the material will be accurately metered by the belt scale 9 below the belt conveyor device 7 and evenly fall in front of the hopper of the transport vehicle below. After piling up to a fixed height, the crawler wheel 4 moves backward to gradually fill the transport vehicle, which can more accurately control the landing point of the material, ensure that the material is evenly and smoothly loaded into the vehicle, improve the loading speed and the overall operation efficiency, and reduce the overflow and waste of the material by precisely controlling the material dropping point and the loading amount.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
