DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-4 In the embodiments of the utility model, a self-unloading mechanism for a logistics warehouse comprises a base 1, the upper portion of the base 1 is provided with a placing table 2, two symmetrical lifting mechanisms 3 are arranged between the placing table 2 and the base 1, one side of the placing table 2 is rotatably connected with a conveying frame 4, one side of the conveying frame 4 is rotatably connected with a buffer seat 5, the top surface of the conveying frame 4 is provided with a speed reducer 6 on both sides, the speed reducer 6 comprises a fixed plate 61 fixedly connected with the top surface of the conveying frame 4, one side of the fixed plate 61 is provided with a connecting frame 611, the connecting frame 611 is fixedly connected with a connecting plate 612 inside.

[0024] Specifically, first, the device is moved to the place where unloading is needed. Since the goods in the warehouse are usually placed in batches, and the size of the goods in the same batch is the same, the distance between the two connecting plates 612 can be adjusted according to the size of the goods, so that the distance between the two connecting plates 612 is the same as the length or width of the goods. Since some goods are stacked relatively high, the worker can stand on the placing table 2, and then the top layer of goods is placed on the conveying frame 4 in turn. According to Figure 1 As shown in the figure, the conveying frame 4 is usually placed obliquely, so it is convenient to take down the goods from a high place. Therefore, when the goods are placed on the conveying frame 4, the goods move to the bottom of the conveying frame 4 under the action of their own gravity. Since the two connecting plates 612 are in contact with the goods and produce friction during the downward sliding of the goods, the speed of the goods moving downward can be reduced, so that the speed of the goods moving downward is not too fast and collision with the goods in the buffer seat 5 can be avoided, thereby avoiding the damage or deformation of the goods.
