[0020] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0021] Please see Figure 1-5 A hydraulic box tipper includes a base frame 1, a support frame 2 fixed to the top of the base frame 1, multiple connecting seats 3 fixed to the top of the support frame 2, two tilting hydraulic cylinders 4 hinged to the top of the base frame 1, a mounting frame 6 hinged to the top of the tilting hydraulic cylinders 4, multiple connecting plates 7 fixed to the surface of the mounting frame 6, the connecting plates 7 being hinged to the surface of the connecting seats 3, multiple self-locking casters 5 fixed to the bottom of the base frame 1, an extension plate 8 fixed to the surface of the mounting frame 6, a clamping hydraulic cylinder 9 fixed to the top of the extension plate 8, one end of the clamping hydraulic cylinder 9 penetrating the extension plate 8 and fixed with a pressure sensor 25, a movable plate 10 fixed to the bottom of the pressure sensor 25, a buffer structure provided at the bottom of the movable plate 10, multiple wheel frames 13 fixed to the surface of the mounting frame 6, unloading rollers 14 rotatably connected to the surface of the wheel frames 13, a drive structure mounted on the surface of the mounting frame 6, a controller 15 fixed to the surface of the support frame 2, and multiple support extension plates 28 fixed to the surface of the mounting frame 6.

[0022] Through the above technical solution, the base frame 1 constructs a basic load-bearing platform through the support frame 2. The hinged design of the connecting seat 3 and the connecting plate 7 forms a multi-axis linkage system. With the extension and retraction action of the tilting hydraulic cylinder 4, the mounting frame 6 is stably tilted. The self-locking universal wheel 5 integrates a locking mechanism to lock the device when the equipment is stationary, ensuring that the equipment does not shift during operation. The combination of the extension plate 8 and the clamping hydraulic cylinder 9 enables the clamping hydraulic cylinder 9 to drive the buffer mechanism to clamp the goods. The pressure sensor 25 monitors the clamping force value in real time and realizes closed-loop feedback adjustment through the controller 15. The wheel frame 13 and the unloading roller 14 cooperate with the drive structure to realize multi-axis synchronous drive, which transports the tilted goods out of the mounting frame 6 to realize automatic unloading. The support extension plate 28 forms an auxiliary load-bearing surface to effectively distribute the load pressure.

[0023] The bottom buffer structure of the movable plate 10 includes a buffer spring 11. One end of the buffer spring 11 is fixedly connected to the surface of the movable plate 10, and the other end of the buffer spring 11 is fixed with a clamping plate 12.

[0024] Through the above technical solution, when the clamping plate 12 comes into contact with the goods, the buffer spring 11 absorbs the impact energy through elastic deformation, which significantly reduces the damage rate of the goods and extends the service life of the equipment.

[0025] The surface drive structure of the mounting frame 6 includes an extension frame 16, which is fixed to the surface of the mounting frame 6. A geared motor 17 is fixed to the surface of the extension frame 16. Two bearings 18 with seats are fixed to the surface of the mounting frame 6. A drive shaft 19 is fixed to the inner wall of the bearings 18. The output shaft of the geared motor 17 is fixedly connected to one end of the drive shaft 19. Multiple first bevel gears 20 are fixed to the surface of the drive shaft 19. Second bevel gears 21 mesh with the surfaces of the first bevel gears 20. A driven shaft 22 is fixed to the surface of the second bevel gears 21. One end of the driven shaft 22 passes through the wheel frame 13 and is fixedly connected to the surface of the unloading roller 14.

[0026] Through the above technical solution, the geared motor 17 outputs low-speed, high-torque power to the drive shaft 19. The drive shaft 19 and the first bevel gear 20 form the main transmission system, and the second bevel gear 21 and the driven shaft 22 form a vertical transmission pair, realizing the 90-degree rotational transmission of power. Thus, when the geared motor 17 starts, multiple unloading rollers 14 rotate synchronously on the surface of the wheel frame 13 to complete the unloading and conveying of goods.

[0027] The mounting bracket 6 has a protective shell 23 fixed on its surface. The drive shaft 19 and the driven shaft 22 both pass through the protective shell 23, and the drive shaft 19 and the driven shaft 22 are rotatably connected to the surface of the protective shell 23 through the penetration.

[0028] Through the above technical solution, the protective shell 23 can effectively prevent foreign objects from coming into contact with the first bevel gear 20 and the second bevel gear 21, and avoid damage to the first bevel gear 20 and the second bevel gear 21 from collision.

[0029] A telescopic rod 26 is provided on the inner side of the buffer spring 11. One end of the telescopic rod 26 is fixedly connected to the surface of the movable plate 10, and the other end of the telescopic rod 26 is fixedly connected to the surface of the clamping plate 12.

[0030] Through the above technical solution, the telescopic rod 26 can guide the movement direction of the clamping plate 12, prevent the buffer spring 11 from bending and deforming when compressed, and ensure that the clamping plate 12 moves in a straight line.

[0031] Two guide rods 24 slide through the surface of the extension plate 8, and one end of the guide rod 24 is fixedly connected to the surface of the movable plate 10.

[0032] Through the above technical solution, the guide rod 24 and the linear bearing of the extension plate 8 cooperate to form a high-precision sliding pair. The symmetrical layout of the double rods eliminates the lateral torque, improves the motion accuracy of the movable plate 10, and ensures the linear movement of the movable plate 10.

[0033] A rubber buffer plate 27 is fixed to the top of the support frame 2.

[0034] Through the above technical solution, when the tilting hydraulic cylinder 4 retracts, the mounting bracket 6 gradually rotates towards the top of the support frame 2, and the rubber buffer plate 27 can contact the bottom of the mounting bracket 6, thereby absorbing the impact force brought by the mounting bracket 6 and improving the service life of the mounting bracket 6.

[0035] In use, after moving the device to the desired position and connecting the tilting hydraulic cylinder 4 and clamping hydraulic cylinder 9 to the external hydraulic oil delivery equipment, lock the self-locking caster wheel 5 to fix the device position. Then, place the goods on the surface of the unloading roller 14 and the top of the support plate 28. Then, operate the clamping hydraulic cylinder 9. Under the monitoring of the pressure sensor 25, the clamping hydraulic cylinder 9 pushes the movable plate 10 towards the goods. The buffer structure achieves flexible clamping through the synergistic action of the buffer spring 11 and the telescopic rod 26, fixing the position of the goods and preventing them from loosening during the tilting process. After that, the tilting hydraulic cylinder... 4. Retraction begins, pulling the mounting frame 6 to rotate around the composite hinge point of the connecting seat 3 and the connecting plate 7, so that the mounting frame 6 rotates to the bottom and contacts the rubber buffer plate 27. The rubber buffer plate 27 buffers the mounting frame 6 and prevents over-tilting, achieving the effect of the mounting frame 6 carrying the goods and then entering the unloading stage. The clamping hydraulic cylinder 9 retracts and stops clamping the goods. The reduction motor 17 drives the unloading roller 14 to rotate synchronously through multiple bevel gear sets. Under the drive of the unloading roller 14, the goods gradually detach from the surface of the unloading roller 14 and enter the subsequent receiving equipment, completing the automatic unloading process.
