[0013] In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model are described clearly and completely below in conjunction with the embodiments. Example 1

[0014] The present utility model provides a bucket wheel loader with two crawler tracks. As described in the Fig. 1 to 6, the bucket wheel loader with two crawler belts comprises a bucket wheel loader 1, wherein a boom conveyor belt 2 is fixedly mounted at one end of the bucket wheel loader 1, symmetrically movable connecting arms 16 are connected inside the boom conveyor belt 2, a bucket 3 is fixedly connected to the ends of the connecting arms 16, a support platform 8 is fixedly connected to the lower end of the bucket 3, support frames 5 are fixedly connected to both ends of the support platform 8, crawler wheels 4 are fixedly mounted to both sides of the lower ends of the support frames 5, a belt conveyor system 7 is fixedly mounted to both sides of the lower end of the support platform 8, a scraper blade 6 is fixedly mounted at the lower end of the support platform 8, and a belt scale 9 is fixedly mounted inside the belt conveyor system 7.

[0015] As in the Fig. 1 and Fig. As shown in Figure 6, a fixed rod 13 is fixedly connected between two fixed blocks 11 at the position below a first bolt 22. A mounting hole 14 is provided in the center of the upper end of the fixed rod 13. A U-shaped part 17 is mounted on one end of each connecting arm 16. A second bolt 21 is movably connected inside the U-shaped part 17. A second nut 20 is threadably connected at the top position of the U-shaped part 17 on the outside of the second bolt 21. Through the cooperation of the second bolts 21 and the second nut 20, the vertical vibration of the connecting arms 16 can be effectively prevented, thereby increasing the stability of the entire structure.

[0016] As in the Fig. 1 and Fig. 4, at the lower end of one end of the cantilever conveyor 2, a hard disk 10 is fixedly connected, on both sides of the lower end of the hard disk 10, two fixed blocks 11 are fixedly connected, in each of the two fixed blocks 11, the first screw 22 passes through and is movably connected, the first screw 22 passes through the connecting arm 16 and is connected inside the connecting arm 16, and is movably connected to the connecting arm 16, at the position of one end of the connecting arm 16 on the outside of the first screw 22, a first nut 18 is threadedly connected. Through the cooperation of the first screws 22 and the first nut 18, the stability of the connection between the connecting arms 16 and the hard disk 10 is strengthened, thereby ensuring the normal function of material conveyance.

[0017] As in the Fig. 1 and Fig. As shown in Figure 2, the horizontal height of the bottom of the scraper blade 6 is different from the horizontal height of the belt conveyor 7. The scraper blade 6 with different heights can more effectively distribute the material evenly on the belt conveyor and enable accurate loading of the material.

[0018] As in the Fig. 1 and Fig. As shown in Figure 2, the shape of the bucket 3 is conical. The conical design reduces the possibility of material accumulating in corners or at the edges and lowers the risk of blockages.

[0019] As in the Fig. 1 and Fig. As shown in Figure 5, the diameter of the fixed rod 13 is equal to the inner diameter of the U-shaped part 17. The diameter of the fixed rod 13 is equal to that of the U-shaped part 17. This ensures close cooperation between them and increases the stability of the structure.

[0020] Working principle: The ends of the connecting arms 16 are clamped to the outer sides of the fixed blocks 11. Then, the fixed rods 13 are clamped with the U-shaped parts 17. After that, the second screws 21 are passed through the U-shaped parts 17 and the mounting holes 14, and the second nut 20 is tightened, effectively preventing the vertical vibration of the connecting arms 16 and increasing the stability of the entire structure. After that, the first screw 22 is passed through the connecting arms 16 and the fixed blocks 11, and the first nut 18 is tightened, firmly connecting the hard disk 10 and the connecting arms 16, ensuring that the device remains stable in the set position and ensuring normal operation of the device.

[0021] The bucket wheel loader 1 is started. The material is conveyed forward by the boom conveyor 2 and fed into the inside of the bucket 3. It falls from the bucket 3 precisely onto the belt conveyor 7. The material is scraped off and evenly distributed by the scraper blade 6. Then, the material is accurately measured by the belt scale 9 under the belt conveyor 7 and evenly dropped into the front of the loading floor of the transporter below. When it has accumulated to a certain height, the crawler wheels 4 move backward and the transporter is filled gradually. This allows the position of the dropped material to be more precisely controlled, so that the material is loaded evenly and evenly into the vehicle. The loading speed and overall work efficiency are increased. By precisely controlling the dropping point and loading amount, overflow and loss of material are reduced.

[0022] The above-mentioned embodiments serve only to explain the technical solutions of the present utility model and not to limit them.
