Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a hydraulic lifting engineering dump truck box, including a box body 1 serving as the dump truck box. A rear plate 2 for lifting and emptying materials from the box body 1 is rotatably connected to the inner wall of the box body 1. A material unloading auxiliary mechanism is provided on the upper surface of the box body 1, including a material-lifting assembly 4. A sliding groove 6 for moving the material-lifting assembly 4 is provided on the outer wall of the box body 1. The material-lifting assembly 4 includes a motor 45 for driving a lead screw 42 to rotate. The motor 45 is prior art and can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. The motor 45 is mounted on the outer wall of the box body 1 and is supported and fixed by the box body 1. The output shaft of the motor 45 is fixedly connected to a lead screw 42 for driving a sliding block 41 to move. The outer wall of 42 is equipped with a sliding block 41 for moving other components. The end of the sliding block 41 away from the lead screw 42 is fixedly connected to a cleaning frame 49 for cleaning the inner wall of the box 1. The inner wall of the cleaning frame 49 is fixedly connected to a mounting rod 48 for mounting and placing the mounting plate 410. The outer wall of the mounting rod 48 is rotatably connected to the mounting plate 410 for mounting the material scraping plate 43. The lower surface of the mounting plate 410 is slidably connected to the material scraping plate 43 for scraping out the material accumulated inside the box 1. The end of the mounting rod 48 away from the sliding block 41 is fixedly connected to a support block 44 for mounting an electric push rod 46. The inner wall of the support block 44 is equipped with an electric push rod 46 for pushing the material scraping plate 43 to rotate. The output shaft of the electric push rod 46 is hinged to a connecting rod 47 for connecting the material scraping plate 43.

[0033] Reference Figure 2 , Figure 5 , Figure 6The unloading auxiliary mechanism also includes a shielding component 5. The shielding component 5 includes a mounting block 51 for supporting and mounting an elastic winding roller 52. The inner wall of the mounting block 51 is rotatably connected to the elastic winding roller 52. The elastic winding roller 52 is a winding roller with an internal spring. Through elasticity, the shielding cloth 53 is automatically wound and retracted. Since this is existing technology, it will not be described in detail in this case. The outer wall of the elastic winding roller 52 is wrapped with a shielding cloth 53 for covering the car body. The shielding cloth 53 can prevent the materials transported inside the car body from spilling and causing dust. One end of the shielding cloth 53 is fixedly connected to the outer wall of the elastic winding roller 52, and the elastic winding roller 52 realizes automatic winding and retraction. The other end of the shielding cloth 53 is fixedly connected to a connecting plate 54 for connecting the shielding cloth 53 to the material feeding plate 43. The bottom of the connecting plate 54 is installed with a connecting plate 54 for connecting the material feeding plate 43. The connecting plate 54 is connected to the magnetic suction piece 58 of the feeding plate 43. The outer wall of the mounting block 51 is fixedly connected to a top block 55 for limiting the connecting plate 54. The top block 55 can prevent the elastic winding roller 52 from over-winding the shielding cloth 53. The shielding assembly 5 also includes a fixing groove 56 and a fixing block 57. The fixing groove 56 is used to cooperate with the fixing block 57 to drive the shielding cloth 53 to extend when the feeding plate 43 moves. The fixing groove 56 is opened on the outer wall of the connecting plate 54. The fixing block 57 is fixedly connected to the upper surface of the feeding plate 43. The shape of the fixing block 57 is set as a hook shape with an inclined surface at the top. When the connecting plate 54 is not pulled, the fixing block 57 is avoided from affecting it. The fixing block 57 fits into the fixing groove 56. The top block 55 contacts the rear surface of the connecting plate 54 and supports the connecting plate 54 above the feeding plate 43, so that the connecting plate 54 is always in a state of being pulled.

[0034] Reference Figure 2 , Figure 4 , Figure 5The lead screw 42 is rotatably connected to the inner wall of the slide 6 to prevent dust accumulation on the outer wall of the lead screw 42. The sliding block 41 is slidably connected to the inner wall of the slide 6. The number of sliding blocks 41 and mounting rods 48 is set to two sets. The two sets of sliding blocks 41 and mounting rods 48 are symmetrically arranged with the center line of the support block 44 as the axis of symmetry. The cleaning frame 49 slides on the inner wall of the box 1, and the cross-sectional shape of the cleaning frame 49 is set to trapezoidal. When the cleaning frame 49 slides on the inner wall of the box 1, it can scrape and clean the debris remaining on the inner wall of the box 1. The connecting rod 47 is hinged to the upper surface of the scraper plate 43. Due to the electric push rod 46 in When started, it is pushed vertically downwards. The connecting rod 47 can assist the electric push rod 46 in pulling the material-scraping plate 43 to rotate and slide down. The moving material-scraping plate 43 can assist in tilting the material. The inner wall of the material-scraping plate 43 is provided with an electromagnet 3 for connecting the shielding component 5. When the electromagnet 3 is energized, it attracts the magnetic suction piece 58. When the electromagnet 3 is energized, it will pull the connecting plate 54 with the magnetic suction piece 58 downwards. At this time, the fixing groove 56 and the fixing block 57 are kept on the same plane. When the material-scraping plate 43 moves, the fixing block 57 will be inserted into the fixing groove 56 to ensure the stability of the rolled-up shielding cloth 53.

[0035] Working Principle: Loading Stage: During material loading, the material-scraping plate 43 rotates upward and folds under the mounting plate 410 by the retraction action of the electric push rod 46, avoiding interference with the loading operation. At this time, the electromagnet 3 is de-energized, and the shielding cloth 53 remains wound up under the elastic force of the elastic winding roller 52. The connecting plate 54 is suspended above the material-scraping plate 43 by the limiting action of the top block 55. The fixing block 57 and the fixing groove 56 are separated. The hydraulic lifting system is activated to tilt the box 1, and the rear plate 2 flips down and opens around the rotation axis. First, the material-scraping assembly 4 moves a certain distance, and the electric push rod 46 is activated to push the connecting rod 47 downward, causing the material-scraping plate 43 to rotate downward and unfold around the mounting rod 48. During the movement, the material-scraping plate 43 scrapes the material outward evenly and stably. When the material does not need to be scraped, the electromagnet 3 is energized to generate magnetic attraction, which attracts the magnetic piece 58 at the bottom of the connecting plate 54 and moves it downward, causing the fixing groove 56 and the fixing block 57 to form a lock. In conjunction with the shielding cloth 53, a linkage relationship is established between the shielding cloth 53 and the material scraping plate 43. The motor 45 drives the lead screw 42 to rotate, causing the sliding block 41 to move backward along the slide groove 6. At the same time, the shielding cloth 53 is synchronously unfolded by the traction of the fixed block 57 and the fixed groove 56, forming a dust-proof barrier. As the cleaning frame 49 moves with the sliding block 41, its trapezoidal cross-section structure continuously scrapes away residual materials on the inner wall of the box 1. Furthermore, the trapezoidal cross-section of the cleaning frame 49 can reduce the impact on the movement of the cleaning frame 49 during the unloading process. After the unloading is completed, the motor 45 reverses to drive the sliding block 41 to reset, the electric push rod 46 retracts to drive the material scraping plate 43 to rotate upward and reset, the electromagnet 3 is de-energized and releases the magnetic attraction, and the elastic winding roller 52 automatically retracts the shielding cloth 53. The cleaning frame 49 can clean the inner wall of the box 1 multiple times during the movement to ensure that there is no material residue. The hook-shaped design of the fixed block 57 automatically disengages from the fixed groove 56 during the reset, ensuring that all components return to their positions smoothly.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
