[0008] Preferably, the buffer is a cuboid sleeve arranged on the horizontal plate inside the side rod.

[0009] Preferably, the buffer is connected to the horizontal plate by a bolt and / or a screw passing through the bottom of the buffer.

[0010] Preferably, a limiting body for limiting the up-and-down movement of the linkage rod in the fully opened state of the tray is arranged above the side rod on which the buffer is arranged.

[0011] Preferably, the limiting body is a limiting roller with a horizontal axis, and the side of the linkage rod facing the connecting rod is provided with a block matched with the limiting roller, and the limiting roller is pressed on the block in the fully opened state of the tray.

[0012] Preferably, the limiting roller is arranged on the side of a vertical shaft through a adapter frame, the vertical shaft is rotatably connected to the side rod, and the lower part of the vertical shaft is connected to the tray switch mechanism.

[0013] Preferably, the tray switch mechanism comprises a carrier plate provided with at least one blocking object, the blocking object blocks the downward rotation of the pair of trays to open in the closed state, the carrier plate comprises a protruding part matched with an external blocker to drive the carrier plate to rotate to release the restriction of the blocking object on the tray, and the carrier plate is further connected to a reset member to keep the blocking object in the position of restricting the downward rotation of the tray to open in the closed state.

[0014] Preferably, the blocking object is two, and the two blocking objects respectively limit one of the pair of trays.

[0026] Example 1

[0027] The following description, in conjunction with the accompanying drawings, illustrates the drop-type parcel transport vehicle disclosed in this utility model. Figure 1 As shown, it includes a frame 100 and at least one pair of trays 200 rotatably and openably disposed on the frame 100. At least one side of the pair of trays 200 is connected by a linkage rod 300 so that they can open and close synchronously. A buffer 400 is provided on the side rod 110 of the frame 100 on the same side as the linkage rod 300. When the pair of trays 200 are fully open, the linkage rod 300 is mounted on the buffer 400.

[0028] Specifically, the frame 100 includes two side rods 110 and connecting shafts 120 connected between the two side rods 110 and located at both ends thereon. In one embodiment, each connecting shaft 120 may have only one tray 200, in which case the length of the tray 200 may be relatively long. At least one side of the two trays 200 is connected by the linkage rod 300; alternatively, both sides of the two trays 200 may be connected by the linkage rod 300.

[0029] In another embodiment, two trays 200 can be connected to each of the connecting shafts 120. In this case, the two trays 200 can be set to be relatively short, so that two pairs of trays 200 are provided on the two connecting shafts 120. The trays 200 that are directly opposite each other are a pair and they open and close synchronously. That is, the two pairs of trays 200 are connected by a linkage rod 300 on the side of the side rod 110.

[0030] As attached Figure 1 As shown, the material tray 200 includes a rotating drum 210, which is rotatably connected to the connecting shaft 120 via bearings. Two baffles 220 are provided at both ends of the rotating drum 210, and a material carrier plate 230 is disposed between the two baffles 220. Simultaneously, a connecting arm 220 is connected to at least one end of the rotating drum 210 near the side rod 110. The two connecting arms 220 of a pair of material trays 200 are approximately perpendicular, and the two connecting arms 220 of a pair of material trays 200 are hinged to both ends of a linkage rod 300. A reset wheel 250 is provided on the back of one of the material trays on the connecting shaft.

[0031] To facilitate the installation of the buffer 400 and to fully utilize its vibration damping effect, the buffer 400 is a cuboid sleeve that is fitted onto the horizontal plate 111 inside the side rod 110. Meanwhile, to ensure the connection and fixation between the buffer 400 and the horizontal plate 111, the buffer 400 is connected to the horizontal plate 111 by bolts and / or screws passing through its bottom.

[0032] As attached Figure 1 Appendix Figure 2 As shown, in order to prevent the tray 200 from shaking when it is open, a limiting body 500 is provided above the side rod 110 of the buffer 400 to limit the up and down movement of the linkage rod 300 connected to the tray 200 when it is fully open, in cooperation with the buffer 400.

[0033] The limiting body 500 can be a block or a ball. Preferably, the limiting body 500 is a limiting roller with a horizontally extending axis, and the linkage rod 300 is provided with a block 310 matching the limiting wheel 140 on the side facing the connecting rod. When the material tray 200 is fully open, the limiting roller presses on the block 310.

[0034] Furthermore, to prevent the limiter 500 from affecting the movement of the linkage 300 when the material tray 200 is closed, as shown in the attached... Figure 1 Appendix Figure 3 As shown, the limiting roller is mounted on the side of a vertical shaft 700 near the tray via an adapter frame 600. The vertical shaft 700 is rotatably connected to the side rod 110. The vertical shaft 700 is located near the middle of the length direction of the side rod 110, and a tray switching mechanism 800 is connected below the vertical shaft 700. The tray switching mechanism 800 can restrict the opening of the tray 200 when the tray 200 is closed, and can cooperate with an external structure (not shown in the figure) to release the restriction on the tray 200, thereby allowing the tray 200 to rotate downwards and open.

[0035] As attachedFigure 3 As shown, the tray switching mechanism 800 includes a carrier plate 810. The specific shape of the carrier plate 810 can be set as needed. Preferably, the carrier plate 810 is approximately L-shaped. The first support 811 of the carrier plate 810 abuts against the tray 200 and is provided with at least one stop 820. When the pair of trays 200 are closed, the stop 820 prevents the pair of trays 200 from rotating downwards to open. The stop 820 can be any object, such as a swivel ball or a block. Preferably, the stop 820 is a blocking wheel, and the axis of the blocking wheel is parallel to the axis of the limiting roller. More preferably, there are two stops 820, and the two stops 820 respectively limit one of the pair of trays 200. At the same time, the side of the tray 200 is provided with a stop block 260 that matches the stop 820.

[0036] As attached Figure 1 Appendix Figure 3 As shown, the second branch 812 of the carrier plate 810 includes a protrusion 813 that cooperates with an external stopper to drive the carrier plate 810 to rotate so that the stopper 820 releases the restriction on the tray 200. The protrusion is the portion of the second branch 812 that extends outside the side bar 110. Thus, when the protrusion 315 is blocked by an object during the forward movement of the drop-down parcel transport vehicle, the carrier plate 810 is driven to rotate as the drop-down parcel transport vehicle continues to move forward. This causes the stopper 820 to move to the outside of the tray 200 or the stop 260 so that the tendency of the tray 200 to rotate downward is no longer restricted. The carrier plate 810 is also connected to a reset member 830 to keep the stopper 820 in the position where the tray 200 is in the downward rotation open position under the restricted closed state. The reset member 830 is, for example, a tension spring or torsion spring connected between the carrier plate 810 and the side bar 110. When the protrusion 315 is no longer blocked by the object, the reset member causes the carrier plate to rotate in the opposite direction and return to a position that can limit the material tray in the closed state.

[0037] Furthermore, similar to existing technologies, as shown in the appendix... Figure 1 As shown, the side rod 110 is also equipped with components such as traveling wheels 130 and limiting wheels 140. Their specific positions can be designed as needed and are not limited here. Meanwhile, to facilitate the connection of the drop-type parcel transport vehicle, joint bearings 150 are provided at both ends of one side rod 110, and vibration damping pads 160 are provided at both ends of the other side rod 110. Of course, this is not mandatory; for example, the drop-type parcel transport vehicle can be connected via a chain, as in existing technology, which will not be elaborated here.
