[0024] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Example 1

[0027] The bag-drop sorting unit disclosed in this utility model will be described below with reference to the accompanying drawings. Figure 1 As shown, it includes a frame 100, on which at least a pair of drop trays 200 are rotatably disposed. A locking and releasing mechanism 300 is provided at at least one side of the support rod 110 of the frame 100. The locking and releasing mechanism 300 includes two side-by-side support members 310. When the pair of drop trays 200 are in the closed state, the two support members 310 respectively limit one drop tray 200; the two support members 310 can be moved to a position where the drop trays 200 are not limited.

[0028] As attached Figure 1 Appendix Figure 2 As shown, the frame 100 includes two support rods 110 and a horizontal shaft 120 connected to both ends of the two support rods 110. One side of the drop tray 200 is rotatably connected to the horizontal shaft 120 via a bearing. The drop tray 200 includes a cylinder 210 rotatably connected to the horizontal shaft 120 via a bearing. Both ends of the cylinder 210 are connected to side plates 220, and a support plate 230 is connected between the two side plates 220 for receiving goods. Simultaneously, the end of the cylinder 210 near the support rods 110 is connected via a synchronization mechanism 400, allowing the two drop trays 200 to open and close simultaneously. The synchronization mechanism 400 includes a synchronization rod 410 and synchronization arms 420 hinged to both ends of the synchronization rod 410. Each synchronization arm 420 is fixed to the end of the cylinder 210. Furthermore, one of the drop trays has a closing roller 250 on its back, which cooperates with an external structure to close the opened drop tray.

[0029] There can be only one pair of drop trays. In this case, the locking and releasing mechanism 300 can be set on both of the support rods 110, so that both sides of the pair of drop trays 200 can be supported by the support member 310, thereby enabling the drop trays 200 to receive maximum support. This structure can effectively meet the needs of sorting heavy objects.

[0030] Of course, in other embodiments, as shown in the appendix Figure 1 As shown, the drop trays 200 can be in pairs, and a locking and releasing mechanism 300 is provided on the support rod 110 on the outer side of each pair of drop trays 200. In this structure, the drop trays 200 at the corresponding positions can be opened for sorting according to the position of the goods, which helps to reduce operating costs.

[0031] As attached Figure 1 As shown, the locking and releasing mechanism 300 includes a rotating shaft 320 rotatably mounted on the support rod. The rotating shaft 320 is located near the middle of the support rod along its length. The rotating shaft 320 extends vertically and can be rotatably connected to the support rod via a bearing or bushing fixed to the support rod. A rotating plate 330 is provided at the lower end of the rotating shaft 320. The rotating plate 330 is approximately L-shaped and includes a first plate portion 331 and a second plate portion 332. The rotating shaft 320 is connected to the first plate portion 331. The first plate 331 is located near the second plate portion 332, which is positioned towards the inner side of the support rod and has a connecting block 340 on its outer side. Two support members 310 are provided at the connecting block 340. The support members 310 are preferably two support wheels, but can also be blocks or omnidirectional balls. The axis of the support wheels is perpendicular to the length direction of the second plate portion 332. When the support wheels are supported below the drop plate 200, their axes are parallel or approximately parallel to the horizontal axis 120. At this time, the first plate portion 331 includes a rotation drive portion 333 that extends to the outer side of the support rod. The rotating plate 330 is connected to an energy storage member 350 to maintain it in a position that provides support to the drop plate in the closed state. That is, after the rotating plate 330 rotates, the energy storage member 350 enables the rotating plate 330 to rotate, thereby restoring the axis of the support wheels to a state that is parallel or approximately parallel to the horizontal axis 120. The energy storage component 350 may be, for example, a spring or torsion spring connected between the rotating plate 330 and the support rod, and may be configured according to specific needs, which is not limited here.

[0032] Furthermore, in order to prevent the support member 310 from affecting the descent of the two drop plates 200, a stop block 240 adapted to the support member 310 is provided on the side of the drop plate near the support rod. The stop block 240 is located on the side of the drop plate away from the axis around which it rotates, so that when the drop plate 200 is in the closed state, the stop block 240 is mounted on the support member 310.

[0033] Furthermore, since it is impossible to install components for connecting adjacent bag-drop sorting units at the horizontal axis 120, rod end bearings 150 near both ends of one side of the support rod 110 can only be provided for connection with adjacent bag-drop sorting units. Simultaneously, since the bag-drop sorting units need to turn at bends during operation, shock-absorbing pads 130 protruding from both ends of the other side of the support rod 110 are provided to ensure smooth turning of the connected bag-drop sorting units. Specifically, the rod end bearings 150 are connected to the inner support rod 110, and the shock-absorbing pads 130 are connected to the outer support rod 110. Moreover, to ensure reliable connection and proper functioning of the shock-absorbing pads 130, the outer contour of the shock-absorbing pads 130 is cuboid, and rectangular through holes are formed on them. The shock-absorbing pad 130 is sleeved on the connecting plate 140 provided on the top of the support rod 110 through a through hole, and the opposite sides of the shock-absorbing pads 130 at both ends are connected to the connecting plate 140 by screws or bolts.

[0034] As attached Figure 2 As shown, the rod end spherical bearing 150 is connected to the upper end of a fixed shaft 160, which extends vertically. Simultaneously, the lower end of the fixed shaft 160 is connected to a guide wheel 500 located below the support rod 110. The guide wheel 500 is used to limit the horizontal movement of the bag-dropping sorting unit. Furthermore, a wheel seat 600 is also connected to the fixed shaft 160, and a movable wheel 700 is connected to the wheel seat. The axis of the movable wheel 700 extends horizontally, and the movable wheel 700 is used to move the frame 100 along the track. This effectively simplifies the structure of the bag-dropping sorting unit, making the overall structure more compact. Of course, a movable wheel is also provided on the connecting rod on the other side.

[0035] As attached Figure 2 Appendix Figure 3 As shown, a damping block 800 is also provided on the inner side of the connecting rod. The damping block 800 is used to support the synchronizing rod 410 when the drop plate 200 rotates downward to open. That is, when the drop plate 200 is fully opened, the synchronizing rod 410 rests on the damping block 800 to achieve shock absorption. At the same time, a pressure roller 900 that rotates synchronously with the upper end of the rotating shaft 320 is also connected. The axis of the pressure roller 900 is parallel to the supporting roller, and when the drop plate 200 is fully opened, the pressure roller 900 is limited above the synchronizing rod 410, thereby restricting the upward movement of the synchronizing rod 410. Of course, a pad 430 can be provided on the side of the synchronizing rod 410 to cooperate with the pressure roller 900 to restrict the upward movement of the synchronizing rod. This can effectively prevent frequent vibrations of the opened drop plate from affecting the mechanical life.
