[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a dump truck, including a body 1, a truck bed 2 rotatably mounted on the surface of the body 1, a cleaning device 3 provided on the inner side of the truck bed 2, and an auxiliary device 4 provided on the surface of the scraper 31.

[0025] The specific setup and function of its cleaning device 3 and auxiliary device 4 will be explained below.

[0026] Reference Figures 1-2 and Figure 4As shown in this embodiment: the cleaning device 3 includes a groove 35 formed on the side wall of the truck bed 2. A sliding plate 33 is slidably connected to the inner wall of the groove 35. A scraper 31 is fixedly connected to one end of the sliding plate 33 located on the inner side of the truck bed 2. The scraper 31 is located on the inner side of the truck bed 2. By setting up the cleaning device 3, the cleaning of clay adhering to the bottom side of the truck bed 2 is facilitated, avoiding the phenomenon that clay adhering to the bottom side of the truck bed 2 is inconvenient to clean, and further improving the performance of the dump truck. A positioning block 38 is fixedly connected to the side wall of the truck bed 2. A lead screw 34 is rotatably connected inside the positioning block 38. The lead screw 34 and the sliding plate 33 are internally threaded. Since the lead screw 34 is threadedly connected to the sliding plate 33 in the groove 35 of the side wall of the truck bed 2, the rotational motion of the lead screw 34 is converted into the horizontal linear motion of the sliding plate 33 along the groove 35. A mounting plate 37 is fixedly installed on the side wall of the truck bed 2. A motor 36 is fixedly installed on the inner side of the mounting plate 37. The output end of the motor 36 is fixedly connected to the lead screw 34. The operation of motor 36 drives screw 34 to rotate synchronously. A rubber pad 32 is glued to the lower side of scraper 31, and the rubber pad 32 is in contact with the inner side of the bucket 2. The rubber pad 32 glued to the lower side of scraper 31 is in close contact with the inner wall of bucket 2, which can enhance the fit between scraper 31 and bucket 2, and ensure that the crushed clay and residual materials are thoroughly scraped off.

[0027] Reference Figure 1 and Figure 3 As shown, specifically, the auxiliary device 4 includes a fixed strip 41 fixedly connected to the side wall of the scraper 31. Two sliding strips 45 are slidably connected inside the fixed strip 41. An auxiliary strip 42 is fixedly connected to the lower end of the two sliding strips 45, and several scraper blocks 43 are fixedly connected to the lower surface of the auxiliary strip 42. By setting the auxiliary device 4, and by setting the flexibly driveable auxiliary strip 42 and scraper blocks 43, the crushing work before cleaning large pieces of clay material is facilitated, further improving the subsequent processing of adhered and compacted materials. The cross-section of the scraper block 43 is rhomboid, and the lower end of the scraper block 43 has a pointed structure. When the auxiliary strip 42 moves downward, the rhomboid scraper block 43 fixed on its lower surface will contact the compacted material, using the pointed structure of the scraper block 43 to crush the large pieces of compacted material. A drive rod 44 is threadedly connected inside the fixed strip 41, and the drive rod 44 is rotatably connected to the auxiliary strip 42. The rotatable connection between the drive rod 44 and the auxiliary strip 42 will drive the auxiliary strip 42 to move vertically downward along the sliding strips 45 inside the fixed strip 41.

[0028] Working principle: The motor 36 of the cleaning device 3 is started. The motor 36 is fixed on the mounting plate 37 on the side wall of the truck bed 2. Its output end is fixed to the lead screw 34 rotatably connected in the positioning block 38. The operation of the motor 36 will drive the lead screw 34 to rotate synchronously. Since the lead screw 34 is threadedly connected to the slide plate 33 in the slide groove 35 on the side wall of the truck bed 2, the rotational motion of the lead screw 34 is converted into the horizontal linear motion of the slide plate 33 along the slide groove 35. The slide plate 33 then drives the scraper 31 fixed at its end to move horizontally inside the truck bed 2, scraping and unloading the material. The rubber pad 32 glued to the lower side of the scraper 31 is tightly attached to the inner wall of the truck bed 2. This design enhances the fit between the scraper 31 and the truck bed 2, ensuring the complete removal of crushed clay and residual materials. It also prevents the scraper 31 from directly contacting the truck bed 2 and causing scratches on the inner wall. After all the material adhering to the inside of the truck bed 2 has been scraped off, the truck bed 2 is tilted using the original hydraulic lifting system of the dump truck, and the scraped material is unloaded together with the original transported material, completing the entire cleaning and unloading process. By setting up the cleaning device 3, it is convenient to clean the clay adhering to the bottom side of the truck bed 2, avoiding the phenomenon that the clay adheres to the bottom side of the truck bed 2 and is inconvenient to clean, further improving the performance of the dump truck.

[0029] If there are large pieces of hardened clay in the truck bed 2, first operate the auxiliary device 4 to rotate the drive rod 44 inside the fixed bar 41. The drive rod 44 is rotatably connected to the auxiliary bar 42, which will drive the auxiliary bar 42 to move vertically downward along the slide bar 45 inside the fixed bar 41. When the auxiliary bar 42 moves downward, the diamond-shaped scraper 43 fixed on its lower surface will contact the hardened material. The sharp point structure of the scraper 43 will break up the large pieces of hardened material, preventing the large pieces of material from obstructing subsequent cleaning and laying the foundation for efficient scraping. By setting the auxiliary device 4, and by setting the flexibly driven auxiliary bar 42 and scraper 43, it is convenient to break up the large pieces of clay before cleaning, and further improves the subsequent processing of the adhered hardened material.
