[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1-3 The utility model provides a technical solution: a hydraulic tailgate for trucks that is convenient for unloading, comprising a mounting frame 1 and a tailgate 2, wherein the mounting frame 1 is arranged at the rear of the truck, the tailgate 2 is rotatably and liftably arranged on the mounting frame 1, and a first driving component for driving the tailgate to rotate and lift is arranged on the mounting frame 1;

[0020] A placement hole is provided in the middle of the tail plate 2, and a rotating plate 10 is flippably provided in the placement hole. A rotating shaft 19 is provided in the middle of the rotating plate 10. The upper surface of the rotating plate 10 is fixedly connected to the roller conveyor plate 5, and the lower surface of the rotating plate 10 is fixedly connected to the plane conveyor plate 6. A placement groove 18 is provided in the tail plate 2, and a second drive component for driving the rotating shaft 19 to rotate is provided in the placement groove 18. A plurality of positioning grooves 12 are provided inside the rotating plate 10, and a plurality of positioning rods 11 that penetrate the rotating plate 10 and are adapted to the positioning grooves 12 are pullable in the rotating plate 10.

[0021] In this embodiment, the rotating plate 10 is driven to flip by the rotating shaft 19. When the flat conveying plate 6 needs to be used, the rotating shaft 19 is driven to rotate by the second driving component, thereby driving the rotating plate 10 to flip to the flat conveying plate 6, and then the positioning rod 11 is clamped into the positioning groove 12 for fixation, and then it can be used.

[0022] When the roller conveyor plate 5 is needed, the second driving assembly drives the rotating shaft 19 to rotate, thereby driving the rotating plate 10 to flip to the roller conveyor plate 5, and the positioning rod 11 is clamped into the positioning groove 12 for fixation, and then it can be used.

[0023] Furthermore, the first drive assembly includes a lifting hydraulic cylinder 4 and a flipping hydraulic cylinder 3, one end of the lifting hydraulic cylinder 4 is hinged to the mounting frame 1, and the other end of the lifting hydraulic cylinder 4 is hinged to the bottom of the tail plate 2, one end of the flipping hydraulic cylinder 3 is hinged to the mounting frame 1, and the other end of the flipping hydraulic cylinder 3 is hinged to the bottom of the tail plate 2.

[0024] In this embodiment, the first driving assembly is a hydraulic tailgate 2 lifting and rotating driving assembly, which is a prior art and will not be described in detail here.

[0025] Furthermore, the second drive assembly includes a rack plate 7, which is slidably connected to the placement groove 18, and a gear 8 meshing with the rack plate 7 is provided at one end of the rotating plate 10. An electric telescopic rod 9 is provided in the placement groove 18, and one end of the rack plate 7 is fixedly connected to one end of the electric telescopic rod 9.

[0026] In this embodiment, when the rotating plate 10 needs to be flipped, the rack plate 7 is driven to slide in the placement groove 18 by driving the telescopic movement of the electric telescopic rod 9. Since the rack plate 7 is engaged with the gear 8, the sliding of the rack plate 7 will drive the gear 8 to rotate. The rotation of the gear 8 will drive the rotating plate 10 to flip around the rotating axis 19 to the desired position. When the rotating plate 10 is flipped to the appropriate position, the position of the rotating plate 10 is locked by the positioning rod 11.

[0027] Furthermore, the outer ends of several positioning rods 11 are fixedly connected to a connecting plate 16, and a pull plate 17 is provided in the middle of the connecting plate 16. A threaded hole 15 is vertically opened on the outer end surface of each positioning rod 11, and a bolt 20 is threadedly connected to the threaded hole 15.

[0028] In this embodiment, when the position of the rotating plate 10 needs to be adjusted, all the positioning rods 11 connected to the connecting plate 16 are first pulled out simultaneously by the pulling plate 17 to make them disengage from the rotating plate 10, thereby releasing the fixation of the rotating plate 10 and flipping the rotating plate 10. When the rotating plate 10 reaches the appropriate position, the positioning rods 11 are inserted into the corresponding positioning grooves 12 again by pulling the plate 17, and the bolts 20 are rotated to fix them on the rotating plate 10 to ensure the stability of the rotating plate 10.

[0029] Furthermore, a plurality of rotating rods 13 are evenly spaced on the surface of the roller conveyor plate 5 , and a rotating roller 14 is fixedly connected to the surface of each rotating rod 13 .

[0030] In this embodiment, the rotating rods 13 are evenly spaced on the surface of the roller conveyor plate 5. This even distribution can ensure that the goods are evenly stressed during transportation, reducing damage or jamming caused by excessive local pressure.

[0031] The rotating rollers 14 on the roller conveyor plate 5 can significantly reduce the friction between the goods and the conveyor plate, allowing the goods to slide or roll more smoothly, thereby improving loading and unloading efficiency.

[0032] The working principle and usage process of the present invention: After the present invention is installed, the tail plate 2 is first driven to the working state by starting the first drive assembly. When the conveying mode needs to be switched, the electric telescopic rod 9 is started to drive the rack plate 7 to slide in the placement groove 18. Since the rack plate 7 is engaged with the gear 8 at one end of the rotating plate 10, the sliding of the rack plate 7 will drive the gear 8 to rotate, and then the rotating plate 10 will flip around the rotating axis 19. After flipping into place, all the positioning rods 11 are pushed in at the same time by pulling the plate 17 so that they are stuck in the positioning grooves 12 inside the rotating plate 10. Subsequently, the rotating bolts 20 are rotated to fix the positioning rods 11 in the positioning grooves 12 to ensure the stability of the rotating plate 10 during loading and unloading.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
