Description

Technical Field

[0001] The embodiments of this utility model relate to the field of sandbag stacking technology, specifically, to a flood control sandbag stacking device. Background Technology

[0002] Constructing sandbag retaining walls along riverbanks during the flood season is a common and effective flood control method. However, relying entirely on manual labor for the transportation and stacking of sandbags is time-consuming and labor-intensive. Furthermore, the personal safety of construction workers cannot be effectively guaranteed when floods occur. Even if automated palletizing machines are considered to replace manual labor, most palletizing machines in the industrial sector are currently robotic palletizing robots used in factories. These robots are generally fixed-point palletizing machines with a small range of movement, making it impossible to construct long-distance flood control walls. Moreover, the efficiency of the robotic arms picking up and placing sandbags one by one still needs to be improved, and the sandbags are not stable enough after placement. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a flood control sandbag stacking device, which solves the technical problem that the efficiency of traditional robotic arm-type stacking machines for picking up and placing sandbags one by one to construct long-distance flood control walls still needs to be improved.

[0004] According to one aspect, at least one embodiment of the present invention provides a flood control sandbag stacking device, comprising:

[0005] Palletizing cart;

[0006] A conveying device is mounted on the palletizing vehicle and is used to convey sandbags. The conveying device has a conveying end, and the conveying end is equipped with a swaying feeding hood. The feeding hood has a receiving port on one side, which faces the conveying end. The feeding hood has a feeding port at the bottom, and the feeding port is equipped with an opening and closing door. The opening and closing door can control the timing of sandbag feeding, and the feeding hood can adjust the sandbag feeding angle after swaying.

[0007] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein the oscillating axis of the feeding hood is horizontal, and there are two opening and closing doors, both of which are oscillating at the feeding port and symmetrically arranged.

[0008] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, in which each of the opening and closing doors has a connecting part, and the top of the feeding hood is also provided with a driving rod that is raised and lowered. The driving rod has a driving end, and a connecting rod is connected between the driving end and the connecting part. The two ends of the connecting rod are respectively hinged to the driving end and the connecting part. After the driving rod is raised and lowered, it can synchronously drive the two opening and closing doors to swing through the connecting rod to release sandbags.

[0009] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein the stacking vehicle is equipped with a rotating platform, the conveying device is located on the rotating platform, and the rotating axis of the rotating platform is vertical.

[0010] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein the conveying device includes:

[0011] A primary conveyor belt, which is oscillatingly mounted on the palletizing vehicle, is capable of transporting sandbags to a specified height, and the bottom of the primary conveyor belt has a frame section;

[0012] A secondary conveyor belt is slidably connected to the frame. One end of the frame has the conveying end, and the sliding direction and conveying direction of the secondary conveyor belt are the same as the conveying direction of the primary conveyor belt. The primary and secondary conveyor belts can sequentially convey sandbags into the feeding hood.

[0013] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein the swing axis of the primary conveyor belt is horizontal, and the stacking vehicle is also provided with a shaping conveyor device, which is connected to one end of the primary conveyor belt and can shape the sandbags on the primary conveyor belt and transfer them to the secondary conveyor belt.

[0014] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein the shaping and conveying device includes:

[0015] A shaping frame is provided at the top of the frame body and at one end of the primary conveyor belt along the extension direction of the primary conveyor belt;

[0016] Several shaping conveyor rollers are rotatably mounted on the shaping frame and arranged sequentially along the sandbag conveying direction. The shaping conveyor rollers are square rollers.

[0017] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein the shaping and conveying device further includes:

[0018] The gantry frame is fixedly mounted on the top of the shaping frame;

[0019] Two sliders, both of which are raised and lowered on the gantry frame;

[0020] The shaping roller has two ends that are rotatably connected to two sliders. The sliders can drive the shaping roller to descend and press down the shaping sandbag.

[0021] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, wherein baffles are fixedly provided on both sides of the shaping conveyor, 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 shaping conveyor, the primary conveyor belt, or the secondary conveyor belt.

[0022] For example, at least one embodiment of this utility model provides a flood control sandbag stacking device, in which a compaction plate is also provided inside the feeding hood, and the compaction plate can compact the sandbags after it descends.

[0023] The beneficial effects of the embodiments of this utility model are as follows:

[0024] This palletizing device achieves mobility through a palletizing cart, enabling long-distance operation at flood control sites and overcoming the mobility limitations of traditional palletizing machines. The conveying device continuously delivers sandbags to the feeding hood with a receiving port. The opening and closing door at the bottom of the feeding hood precisely controls the timing of sandbag delivery, changing the inefficient mode of one-by-one gripping by robotic arms. At the same time, the feeding hood can swing to adjust the delivery angle, allowing sandbags to be delivered accurately at the appropriate angle. This not only improves palletizing efficiency but also enhances the stability of sandbags after delivery, effectively solving the problems of low efficiency, small movement range, and poor stability of sandbags in traditional flood control technologies.

[0041] 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.

[0042] 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."

[0043] 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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.

[0046] 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.

[0047] like Figures 1-3 As shown, this invention illustrates a sandbag stacking device for flood control in one embodiment. The stacking vehicle includes tracked wheels and a generator set, hydraulic pump station, and electrical control system for controlling the tracked chassis and conveying device 30. When a sandbag is placed at one end of the conveying device 30, the sandbag is transported to the delivery point under its transport action. However, it is not dropped directly but enters the delivery hood. The sandbag is delivered at the appropriate time by selecting the opening and closing timing of the opening and closing door 53. The delivery hood 50 can provide a certain degree of protection and has a certain swinging ability to meet various delivery angles. In the complex and ever-changing flood control site, different terrains and stacking requirements have diverse requirements for the delivery angle of the sandbag. When encountering situations such as changes in the slope of the embankment or irregular shapes of existing sandbag stacks, the delivery hood 50 can swing flexibly, so that the sandbags can be delivered not only by vertical drop, in order to construct a flood control wall.

[0048] Specifically, the receiving port 51 on one side faces the conveying end 31, ensuring that the sandbags can be smoothly transferred from the conveying device 30 to the feeding hood 50. The feeding port 52 at the bottom of the feeding hood 50 is equipped with an opening and closing door 53 that can precisely control the timing of sandbag feeding. Operators can control the opening and closing of the opening and closing door 53 to feed the sandbags to the designated position at the most appropriate time, so that the sandbags are fed one by one in an orderly manner, avoiding the accumulation or misalignment of sandbags.

[0049] like Figures 3-5 As shown, the drive rod 60 is located at the top center of the feeding hood 50 and achieves vertical lifting and lowering movement through a linear guide rail. Its drive end 61 is connected to the connection part 54 of the opening and closing door 53 through a connecting rod 62, and the two ends of the connecting rod 62 are respectively hinged to the two. When the drive rod 60 descends under the drive of the hydraulic cylinder or electric push rod, the drive end 61 pulls the two opening and closing doors 53 to swing outward synchronously through the connecting rod 62, so that the feeding port 52 opens. Conversely, the feeding port 52 is closed, and the two opening and closing doors 53 are controlled synchronously to avoid sandbag jamming.

[0050] like Figures 6-7 As shown, the conveying device 30 on the palletizing vehicle A can be installed on the palletizing vehicle A via the rotary platform D. The rotation axis is in the vertical direction, and this rotation is active rotation with an active drive source. This gives the palletizing vehicle A track wheels and the conveying device 30 on them rotational freedom (e.g., ±90 degrees rotation) to actively adjust the sandbag conveying angle. The rotary platform D can rotate according to the palletizing requirements to adjust the conveying direction of the conveying device 30, expand the working range of the conveying device 30, and enable the sandbags to be accurately conveyed to the designated delivery point.

[0051] like Figures 6-7 As shown, the conveying device 30 consists of a primary conveyor belt 32 and a secondary conveyor belt 33, forming a two-stage relay conveying structure. First, the primary conveyor belt 32 is oscillatingly mounted on the rotary platform D via a hinged seat or directly oscillatingly mounted on the palletizing cart A. Regardless of the form, a frame 320 with a fixed frame is assembled at its bottom, with internal reinforcing ribs to improve rigidity. Its oscillation is driven by two symmetrically arranged hydraulic cylinders. One end of the cylinder is hinged to the frame, and the other end is hinged to the middle of the frame 320. The angle of the primary conveyor belt 32 is adjusted by the extension and retraction of the cylinders to convey the sandbags to the specified height. In addition, the secondary conveyor belt 33 is slidably connected to the slide rail built into the frame 320 via a slider. The slide rail extends along the conveying direction of the primary conveyor belt 32, which ensures that the conveying direction of the secondary conveyor belt 33 is consistent with that of the primary conveyor belt 32, ensuring the continuity of the sandbag relay conveying and quickly conveying the sandbags to a farther position, forming a telescopic two-stage relay conveying structure.

[0052] Throughout the entire conveying process, the sandbags pass sequentially through the primary conveyor belt 32 and the secondary conveyor belt 33 to the feeding hood 50. The rotary platform D can drive the conveying device 30 to rotate horizontally, the primary conveyor belt 32 can adjust its pitch angle, and the secondary conveyor belt 33 can extend and retract to adjust its length. The three work together to achieve precise conveying of the sandbags in three-dimensional space.

[0053] like Figure 6 , Figure 8 , Figure 9 As shown, a shaping conveyor 40 is further installed at one end of the primary conveyor belt 32 to be connected. This arrangement can straighten the shape of the sandbags before they enter the subsequent stacking stage, ensuring the stability and neatness of the stacking.

[0054] Specifically, a shaping structure composed of several square shaping conveyor rollers 42 can be used. These shaping conveyor rollers 42 are arranged sequentially on the shaping frame 41 along the sandbag conveying direction. When the sandbag passes by, the edges of the square rollers can squeeze and comb the irregular parts of the sandbag, making its surface smoother. This can effectively solve the problems of deformation and bulging caused by sandbags during stacking and transportation. After shaping, the sandbags are regular in shape and can fit tightly when stacked, enhancing the overall strength and stability of the flood control wall.

[0055] The shaping and conveying device 40 specifically includes a shaping frame 41 and square shaping conveying rollers 42. The shaping frame 41 is a rectangular frame structure, which is fixed to the top of the frame part 320 of the three-stage conveyor belt by bolts. It is located at the end of the three-stage conveyor belt, and its length direction is consistent with the sandbag conveying direction to ensure that the sandbag can smoothly enter the shaping area. Several square shaping conveying rollers 42 can be arranged at equal intervals in the shaping frame 41 through bearing seats. The two ends of each roller shaft are rotatably connected to the two side frames of the shaping frame 41, and the axial direction of the roller shaft is perpendicular to the sandbag conveying direction. The cross section of the square roller is square to provide sufficient friction and shaping force.

[0056] As an alternative implementation, the square roller can be replaced with an elliptical roller. During rotation, the major and minor axes of the elliptical roller alternately contact the sandbag, generating periodic pressure changes, enhancing the disturbance and redistribution of the filling material inside the sandbag, and further improving the shaping quality.

[0057] The shaping and conveying device 40 specifically includes a shaping frame 41 and square shaping conveying rollers 42. The shaping frame 41 is a rectangular frame structure, which is fixed to the top of the frame part 320 of the three-stage conveyor belt by bolts. It is located at the end of the three-stage conveyor belt, and its length direction is consistent with the sandbag conveying direction to ensure that the sandbag can smoothly enter the shaping area. Several square shaping conveying rollers 42 can be arranged at equal intervals in the shaping frame 41 through bearing seats. The two ends of each roller shaft are rotatably connected to the two side frames of the shaping frame 41, and the axial direction of the roller shaft is perpendicular to the sandbag conveying direction. The cross section of the square roller is square to provide sufficient friction and shaping force.

[0058] As an alternative implementation, the square roller can be replaced with an elliptical roller. During rotation, the major and minor axes of the elliptical roller alternately contact the sandbag, generating periodic pressure changes, enhancing the disturbance and redistribution of the filling material inside the sandbag, and further improving the shaping quality.

[0059] Furthermore, the shaping and conveying device 40 is further enhanced with the addition of a gantry frame 43, sliders 44, and shaping rollers 45, forming an adjustable dynamic shaping mechanism. The gantry frame 43 is an inverted "gate"-shaped steel structure, bolted to the top of the shaping frame 41, spanning the sandbag conveying path. Its uprights are vertically connected to the two side frames of the shaping frame 41 to ensure the stability of the overall structure. Two sliders 44 are symmetrically arranged on the crossbeam of the gantry frame 43, sliding up and down via linear guide rails arranged vertically. The bottom of the sliders 44 is provided with connecting ear plates for mounting the two end shafts of the shaping rollers 45. The shaping rollers 45 are cylindrical rollers covered with an elastic rubber layer. The two end shafts are rotatably connected to the connecting ear plates of the two sliders 44 via bearings, allowing the shaping rollers 45 to rise and fall synchronously under the drive of the sliders 44, while also rotating around their own axis.

[0060] The advantage is that when the sandbag is conveyed to the bottom of the shaping roller 45, the slider 44 can move downward through a hydraulic or electric drive device, driving the shaping roller 45 down to the surface of the sandbag, flattening the protruding part of the sandbag. At the same time, the sandbag moves relative to the surface of the shaping roller 45 during the conveying process, causing the shaping roller 45 to rotate, avoiding damage to the sandbag due to excessive friction. For loosely filled sandbags, the slider 44 can be controlled to lower the shaping roller 45 to a lower position, increasing the pressure and improving the shaping effect.

[0061] like Figure 4 , Figure 8 , Figure 9As shown, baffle plates 14 are fixedly installed on both sides of the shaping conveyor 40, 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 the sandbags from detaching from the shaping conveyor 40, 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 conveying.

[0062] In addition, a compaction plate 70 is added inside the delivery hood. The compaction plate 70 descends under the drive of a cylinder or motor, applying vertical pressure to the sandbags after delivery, compressing the air inside the sandbags and making their surface flat, so as to improve the strength of the flood control wall. The compaction plate 70 can be a circular metal plate with a diameter slightly smaller than the size of the delivery port 52, so as to ensure that it can descend and act on the sandbags after delivery through the delivery port.

[0063] 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.
