[0015] Beneficial effects of the present invention:
[0016] 1. When the container is placed horizontally, the front support seat and the rear support seat are in contact with the four corners of the bottom of the container body. Through the lifting height of the flipping assembly and the sliding cooperation of the sliding rod and the third cross beam, the front support seat and the rear support seat play a certain supporting role on the bottom of the container. During flipping, because the front support seat will rotate together with the flipping assembly, the cross beam is pressed downward and slides downward along the sliding rod to compress the first spring, and the front support seat slides along the surface of the third cross beam through the sliding frame. When the front support seat slides to the vicinity of the rear support seat, it will squeeze the rear support seat, causing it to slide outward along the cross beam through the sliding frame to compress the second spring, thereby providing a position for the front support seat and keeping the front support seat always in contact with the two corners of the container body during the rotation process.
[0017] 2. In the present invention, when the main shaft is driven to rotate by the motor, the connecting plate will also rotate synchronously, and the sliding frame of the front support seat will be pulled by the connecting arm to slide along the surface of the third cross beam. Because the rotation path of the connecting arm is the same as that of the main shaft, the front support seat keeps rotating synchronously with the flipping assembly, and always maintains the supporting and wrapping effect on the bottom of the container body. At the same time, when the front support seat moves to the bottom of the container body, the second plug-in column part will be inserted along the socket of the splint, so as to keep the flipping assembly and the front support seat rotating as a whole. At the same time, the splint squeezes and contacts the two sides of the container to prevent the container from expanding at this position.
[0018] 3. In the present invention, when the main shaft is driven to rotate by the motor, the connecting plate will also rotate synchronously, and the sliding frame of the front support seat will slide along the surface of the third cross beam through the connecting arm. Because the rotation path of the connecting arm is the same as that of the main shaft, the front support seat keeps rotating synchronously with the flipping assembly, and always maintains the supporting and wrapping effect on the bottom of the container body.
[0019] 4. The present invention uses a one-way hydraulic cylinder to control the lifting and lowering of the first crossbeam, which makes it convenient to match the position of the connecting block with the plug-in end. It is also convenient to lift the container body to a certain height before the subsequent rotation to avoid movement interference at the bottom during rotation. The connecting block is driven by the second hydraulic cylinder to slide along the second crossbeam, and the first plug column will be inserted into the plug-in end to complete the connection between the flip assembly and the top of the container body.
[0020] 5. Compared with the prior art, the present invention, through the cooperation of the flipping assembly and the supporting assembly, plugs and fixes the four corners of the top of the container, and wraps the four corners of the bottom of the container. When flipping, the right top serves as the main driving force, and the supporting assembly at the bottom assists the flipping of the container by traction and suspension, making the flipping of the container more stable and avoiding overload of the flipping assembly.

The bottom of the connecting arm 37 is rotatably connected to the sliding frame 53 of the front support seat 51 through a rotating shaft, and the connecting plate 36 is rotatably connected to the top of the vertical beam 32. When the main shaft 24 is driven to rotate by the motor 23, the connecting plate 36 will also rotate synchronously, and the sliding frame 53 of the front support seat 51 is pulled by the connecting arm 37 to slide along the surface of the third cross beam 35. Because the connecting arm 37 has the same rotation path as the main shaft 24, the front support seat 51 maintains synchronous rotation with the flip assembly 2, and always maintains the supporting and wrapping effect on the bottom of the container body 4.

The connecting plate 36 is rotatably connected to the top of the vertical beam 32, and can move with the vertical beam 32. Before being sent into the container body 4, the two groups of vertical beams 32 are first pushed outward by the first bidirectional hydraulic cylinder 26. At this time, the connecting plate 36 slides along the convex strips 25 at both ends of the main shaft 24 through the card slot to ensure The front support seat 51 and the rear support seat 52 are connected to the main shaft 24 by the sliding card connection, and the rotation of the main shaft 24 can drive the rotation of the connecting plate 36. At the same time, the movable plate 31 at the bottom of the vertical beam 32 slides along the inner part of the slide groove 11, and the front support seat 51 and the rear support seat 52 will move to both sides to facilitate the vehicle transporting the container to enter the bottom plate 1.
