[0014] The swing axis of the gripper frame, the swing axis of the vertical swing arm, and the swing axis of the gripper part are all horizontal, while the swing axis of the horizontal swing arm is vertical.

[0015] For example, at least one embodiment of this utility model provides a flood control sandbag picking and conveying device, wherein the picking vehicle is equipped with a rotating platform, the bag picking conveyor belt is disposed on the rotating platform, and the rotating axis of the rotating platform is vertical.

[0016] For example, at least one embodiment of this utility model provides a flood control sandbag picking and conveying device, wherein a primary conveyor belt is oscillating on a rotating platform, the bottom of the primary conveyor belt has a frame portion, the frame portion is hinged to the rotating platform, and the hinge axis of the frame portion is horizontal, a secondary conveyor belt is slidably connected inside the frame portion, the sliding direction and the conveying direction of the secondary conveyor belt are the same as the conveying direction of the primary conveyor belt, one end of the bag picking conveyor belt is connected to the primary conveyor belt, and the bag picking conveyor belt, the primary conveyor belt and the secondary conveyor belt can sequentially convey sandbags to a specified height.

[0017] For example, at least one embodiment of this utility model provides a flood control sandbag picking and conveying device, wherein one end of the support frame is hinged to one end of the frame part, and the hinge axis of the support frame is horizontal, so that the sandbags on the bag picking conveyor belt can be smoothly transferred to the primary conveyor belt.

[0018] For example, at least one embodiment of this utility model provides a flood control sandbag picking and conveying device, wherein baffles are fixedly provided on both sides of the primary conveyor belt and both sides of the secondary conveyor belt, and the baffles are used to prevent the sandbags from detaching from the primary conveyor belt or the secondary conveyor belt.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0037] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0038] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] like Figures 1-2 As shown, it illustrates a flood control sandbag picking and conveying device in one embodiment of the present invention. The picking vehicle includes tracked wheels 16, and a generator set, hydraulic pump station and electrical control system thereon for controlling the tracked wheels 16 and the following telescopic conveyor for transportation. After picking up the sandbags, the vehicle moves to the designated sandbag stacking position, and then the gripper assembly 23 places the sandbags one by one into the bag picking conveyor belt 21 in a safe position and transports them to the designated placement point to achieve rapid and automatic construction of flood control walls.

[0043] At one end of the support frame 22, near the sandbag stacking point, a bag-retrieving device 20 is provided. It can be connected to the frame part 120 through a horizontal hinge shaft, allowing the bag-retrieving device 20 to swing back and forth to adjust the bag-retrieving angle, or it can be installed at a fixed angle. In addition, the bag-retrieving device 20 can adopt a "gripper + conveyor belt" structure. The gripper assembly 23 is hydraulically driven to move each swing arm, realizing the extension and retraction of the gripper part 2304. When the sandbags are stacked on the ground, the gripper assembly 23 swings downward, the gripper part 2304 opens and clamps the sandbag, and then swings upward to release the sandbag above the bag-retrieving conveyor belt 21. The sandbag is transported to the sandbag delivery point by the bag-retrieving conveyor belt 21.

[0044] like Figure 3 , Figure 6 , Figure 7As shown, the bag-retrieving device 20 consists of a bag-retrieving conveyor belt 21 and a gripper assembly 23. The bag-retrieving conveyor belt 21 is mounted on a support frame 22, which is hinged to the frame portion 120. The conveyor belt swings horizontally and can be tilted according to the height of the sandbag stacking to facilitate sandbag transport. The gripper assembly 23 is located on the support frame 22 and is used to grip sandbags onto the bag-retrieving conveyor belt 21. It includes a gripper frame 2301, a horizontal swing arm 2302, a vertical swing arm 2303, and a gripper portion 2304. Both ends of the gantry-type gripper frame 2301 are swayingly connected to the support frame 22. The horizontal swing arm 2302 is swaying at the top center of the gripper frame 2301, and the vertical swing arm 2303 is swaying at the end of the horizontal swing arm 2302 away from the gripper frame 2301. 2303 has a gripper 2304 at one end of the horizontal swing arm 2302. Each swing axis is horizontal and vertical, respectively, which can realize the position adjustment of the gripper 2304 in three-dimensional space and accurately grip sandbags at different positions. Each swing arm can be realized by a conventionally hinged cylinder. The gripper 2304 can adopt a V-shaped claw + elastic buffer structure. Specifically, the gripper 2304 consists of two symmetrically arranged V-shaped claws. The inner side of each claw is covered with an anti-slip rubber pad to increase the friction with the sandbag and prevent the sandbag from slipping during gripping. The claws are connected to the end of the vertical swing arm 2303 through a hinge shaft, allowing the claws to swing within a certain range to adapt to the unevenness of the sandbag surface. The opening and closing of the claws is driven by a hydraulic cylinder.

[0045] like Figure 2 , Figure 4 , Figure 5 As shown, the bag-collecting conveyor belt 21 is further installed on the rotary platform C of the pickup vehicle. The rotation axis is in the vertical direction. This rotation is actively connected and has an active drive source. This allows the rear vehicle track wheel 16 and the bag-collecting conveyor on it to have rotational freedom (e.g., ±90 degrees rotation). By moving the pickup vehicle B and rotating the rotary platform C, it can adapt to the various sandbag stacking points around the pickup vehicle, so that the bag-collecting conveyor belt 21 is aligned with the sandbag stacking points.

[0046] like Figures 1-5 As shown, the conveying device on the pickup vehicle is the core structure for achieving uninterrupted construction of the flood control wall. The bag-picking and conveying device alone is insufficient to adapt to more situations, such as some long-distance situations. Therefore, a primary conveyor belt 12 and a secondary conveyor belt 13 are added. The secondary conveyor belt 13 can slide actively within the frame part 120 at the bottom of the primary conveyor belt 12. The two sets of conveyor belts can transport the sandbags to the stacking front vehicle in sequence. For the sliding structure, a slider matching the built-in guide rail in the frame part 120 can be provided at the bottom of the secondary conveyor belt 13. The guide rail extends along the conveying direction of the primary conveyor belt 12, and the slider is slidably connected to the guide rail, which can ensure that the conveying direction of the primary conveyor belt 12 is consistent with the conveying direction of the secondary conveyor belt 13, and ensure the continuity of the relay conveying of sandbags.

[0047] In addition, the frame portion 120 at the bottom of the primary conveyor belt 12 is hinged to the pickup vehicle. The hinge axis is horizontal, and the hinge is also an active connection with an active drive source. This allows the primary conveyor belt 12 to swing up and down. When there is a height difference between the sandbag drop point and the output end of the conveying device, the hinge structure allows the primary conveyor belt 12 to be adjusted to a suitable angle.

[0048] like Figure 3 As shown, one end of the support frame 22 is hinged to one end of the frame part 120, with the hinge axis horizontal, so that the sandbags on the bag-picking conveyor belt 21 can be smoothly transferred to the primary conveyor belt 12. The conveyor belts for picking and transporting are clearly separated, and the angle between the two can be changed or finely adjusted so that the bag-picking device 20 can avoid some obstacles.

[0049] like Figure 2 As shown, baffle plates 14 are fixedly installed on both sides of the primary conveyor belt 12 and both sides of the secondary conveyor belt 13. The baffle plates 14 are used to prevent sandbags from detaching from the primary conveyor belt 12 or the secondary conveyor belt 13. The baffle plates 14 are arranged vertically and are installed on both sides of the conveyor belt by bolts, which play a limiting and guiding role for the sandbags during transportation.

[0050] like Figure 3 , Figure 6 As shown, two guide plates 15 are symmetrically arranged on the support frame 22, with a gap between their bottoms and the top surface of the bag-collecting conveyor belt 21. One end of each guide plate 15 is connected to the baffle plate 14 of the primary conveyor belt 12, and the gripper 2304 is located between the two guide plates 15. Structurally, the two guide plates 15 form a funnel-shaped channel, with the starting end connected to the baffle plate 14 of the primary conveyor belt 12. This allows the gripper 2304 to accurately guide the sandbags gripped by the gripper 2304 into the bag-collecting conveyor belt 21. The gap at the bottom prevents direct friction between the guide plates 15 and the conveyor belt, ensuring smooth conveying. The gripper 2304 is located between the guide plates 15, ensuring that it is centered in the guiding area when gripping the sandbags, reducing offset.

[0051] The gradually decreasing thickness design, with a thicker front end (closer to the gripper 2304), provides strong constraint when the sandbag first enters the bag-retrieving conveyor belt 21, preventing lateral slippage due to gripping posture deviation; while the gradually thinner rear end (away from the gripper 2304) reduces the contact resistance between the sandbag and the guide plate 15, avoiding sandbag jamming or rolling due to excessive friction. This gradual structure acts as a "flexible guide" for the sandbag, which is especially suitable for loosely filled sandbags, ensuring that the sandbag remains stable and does not detach during the transition from the bag-retrieving conveyor belt 21 to the primary conveyor belt 12, laying the foundation for subsequent conveying and stacking processes.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
