[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0026] like Figure 1-4 As shown, a material unloading rack includes a frame 1, a boom 2, a tilting mechanism 3, and a locking mechanism 4. The frame 1 has a loading port 11 on its rear side and a unloading port 12 on its front side, with a blocking rod 13 on the unloading port 12. The boom 2 includes a connecting rod 21 and a crossbar 22. The crossbar 22 is horizontally arranged. The connecting rod 21 is vertically arranged on the left and right sides of the bottom surface of the crossbar 22. The tilting mechanism 3 includes a tilting shaft 31. Two tilting shafts 31 are horizontally arranged, with one end of each tilting shaft 31 facing the frame 1 and fixedly connected to the left and right sides of the frame 1, respectively. The side of the tilting shaft 31 away from the frame 1 is rotatably connected to the bottom of the connecting rod 21. The frame 1 can tilt based on the tilting shaft 31. The installation height of the tilting shaft 31 is higher than the center of gravity of the frame 1, allowing the frame 1 to automatically adjust its state according to the shift of the center of gravity. The locking mechanism 4 is located on the left side of the top surface of the frame 1 and limits the front and rear sides of the left connecting rod 21, thereby restricting the tilting of the frame 1. The goods are placed in the cargo box with an open top. After the cargo box is loaded into the frame 1, the forklift lifts the frame 1 using the boom 2. In this state, due to the large weight of the cargo box, the center of gravity of the frame 1 shifts upward, higher than the connection point between the connecting rod 21 and the connecting shaft. At this time, the frame 1 becomes unstable. When the locking mechanism 4 is opened and no longer limited, the frame 1 will flip forward based on the connecting shaft under the action of gravity, causing the cargo box to flip. At this time, the cargo box is blocked by the blocking rod 13, and the goods inside the cargo box will pour out from its top surface, achieving unloading. After unloading is completed, the center of gravity shifts downward, lower than the connection point between the connecting rod 21 and the connecting shaft. At this time, the rack automatically resets and returns to the initial state.

[0027] The frame 1 has vertical columns 14 on its left and right sides, with two columns 14 on each side of the frame 1, located on the front and rear sides of the tilting shaft 31 respectively. The tilting mechanism 3 also includes mounting plates 32. Two mounting plates 32 are provided corresponding to the two tilting shafts 31, positioned between the two columns 14 on the same side of the frame 1. The side of the mounting plate 32 away from the frame 1 is fixedly connected to the end of the tilting shaft 31 closest to the frame 1. The tilting shaft 31 is positioned between the two columns 14 of the frame 1 via the mounting plates 32, ensuring the overall connection stability of the unloading rack.

[0028] The flipping mechanism 3 also includes a stop 33; the stop 33 is vertically disposed at the end of the flipping shaft 31 away from the frame 1; the stop 33 is used to prevent the connecting rod 21 from coming out, ensuring the safety and reliability of the unloading rack.

[0029] The locking mechanism 4 includes a sleeve 41, a rotating rod 41, and a locking rod 41. The sleeve 41 is horizontally arranged front to back, and its bottom is fixedly connected to the left side of the top surface of the frame 1. The rotating rod 41 is horizontally arranged inside the sleeve 41, with both ends extending outwards, and the rotating rod 41 can rotate inside the sleeve 41. There are two locking rods 41, one end of which is fixedly connected to the front and rear ends of the rotating rod 41, and the other end extends away from the frame 1. When the locking rod 41 is rotated to the left by the rotating rod 41, it will be locked on both sides of the connecting rod 21, preventing the frame 1 from flipping. In this state, the top surface of the frame 1 supports the bottom surface of the locking rod 41, keeping the two locking rods 41 locked. When the locking rod 41 is rotated to the right by the rotating rod 41, the frame 1 is unlocked and can be flipped.

[0030] It also includes a limiting block 5; the limiting block 5 is located on the upper right side of the frame 1 and in front of the right connecting rod 21; the limiting block 5 restricts the flipping direction of the frame 1, so that the frame 1 can only flip forward, preventing the cargo box from falling off.

[0031] The frame 1 has support plates 15 on the left and right sides of the bottom surface; the cargo box is placed on the support plates 15 of the frame 1, and the support plates 15 support the cargo box.

[0032] The bottom surface of the crossbar 22 is provided with a protective layer 23; the protective layer 23 is used to protect the crossbar 22 of the boom 2 and reduce the wear of the crossbar 22 caused by multiple unloading operations.

[0033] The working principle of this utility model is as follows:

[0034] After the cargo box is loaded into the frame 1, the forklift lifts the frame 1 using the boom 2. In this state, due to the large weight of the cargo box, the center of gravity of the frame 1 shifts upward, exceeding the connection point between the connecting rod 21 and the connecting shaft. At this point, the frame 1 becomes unstable and tends to flip. However, under the action of the locking rod 41 of the locking mechanism 4, the frame 1 is locked and cannot flip. When the forklift moves to the unloading location, the locking rod 41 is rotated to the other side to unlock the frame 1. At this point, under the action of gravity, the frame 1 will flip based on the connecting shaft. Under the action of the limit block 5, the frame 1 is only allowed to flip forward. If the frame 1 tends to flip backward, it can be manually adjusted to flip forward. When the frame 1 flips, it causes the cargo box to flip. The cargo box is blocked by the blocking rod 13, and the cargo inside the cargo box is poured out from its top surface and dumped out from the discharge port 12 of the frame 1, thus achieving unloading.

[0035] After unloading is completed, the weight decreases and the center of gravity shifts downward, becoming lower than the connection point between the connecting rod 21 and the flipping shaft 31. At this point, the shelf automatically resets and returns to its initial state, ready for the next unloading operation.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
