Abstract
Description
Technical Field
[0001] This invention relates to the field of equipment technology for windbreak and sand fixation, desertification control and sand barrier construction, and in particular to a sandbag filling machine suitable for continuous filling of slender sandbags. Background Technology
[0002] In desertification control, windbreak and sand fixation, sand barrier construction, and sandy land ecological restoration projects, it is often necessary to fill long, thin sandbags with sand from the site and then lay the sandbags on sand dunes, shifting sand boundaries, vegetation restoration areas, or construction protection areas to form sand-stabilizing, sand-blocking, or sand-guiding structures. These sandbags are usually long, thin, and flexible, and problems such as bag mouth collapse, bag bending, sand blockage, and uneven filling can easily occur during the filling process.
[0003] Current manual bagging methods typically require two workers: one worker spends a long time bending over to open the bag, while the other uses a shovel or other tools to feed sand into the bag. Because the bags are long and narrow, the sand doesn't easily migrate into the deeper parts of the bag after entering, often accumulating near the opening and requiring repeated shaking, pushing, or patting of the bags. This method is labor-intensive, inefficient, and the continuous bending over in sandy environments easily leads to worker fatigue, making it unsuitable for large-scale desertification control projects.
[0004] Furthermore, when directly collecting sand in sandy areas and filling bags, the bagging equipment must be adapted to the soft sand surface environment. If the equipment relies solely on manual shoveling of sand into the bag opening, it still cannot effectively reduce labor intensity; if the equipment only has a common trough guiding structure and lacks the power to promote the migration of sand along the narrow bag body, the sand will still easily accumulate near the bag opening. Therefore, it is necessary to provide a sandbag filling device that can be operated by a single person, can vibrate to collect sand during traction, and can continuously migrate sand from the bag opening into the bag body. Summary of the Invention
[0005] The technical problem to be solved by this invention is that: existing sandbag filling operations rely on manual bag support and manual sand delivery, which is labor-intensive; after the sand enters the bag opening, it is easy to accumulate near the bag opening and it is difficult to continuously migrate into the sandbag; ordinary bagging equipment is difficult to complete sand extraction, sand filling and vibration anti-blocking during the on-site movement of sandy areas, resulting in low continuous bagging efficiency.
[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:
[0007] A sandbag filling machine includes a transport trough, a vibration device connected to the transport trough, the vibration device being connected to a power device, and a sandbag fixing structure and a traction device being provided at one end of the transport trough.
[0008] Furthermore, the transport trough extends along its length and is used to support or guide sandbags. The sandbag fixing structure is set at the sand inlet end of the transport trough to fix and open the sandbag opening. The power device is connected to the vibration device in a transmission connection.
[0009] Furthermore, the sandbag fixing structure includes any one of clamps, clips, pressure plates, elastic clamps, or bolt clamps, used to fix the sandbag opening to the sand inlet end of the transport trough, so that sand can enter the sandbag opening from the sand inlet end.
[0010] Furthermore, the vibration device is a dual-shaft box-type vibrator, the power device is a gasoline engine, and the vibration device is connected to the power device via a belt drive assembly.
[0011] Furthermore, the transport trough is U-shaped in general, including a bottom plate and side plates connected to both sides of the bottom plate. The bottom plate and the side plates together form a bag guide space, and the lower surface of the bottom plate directly forms a sliding contact surface for contacting the sand surface.
[0012] Furthermore, the traction device is configured as a traction handle and also includes a support body, which is a horizontal long plate. The transport trough is inclined at an angle to the horizontal long plate, and the angle formed between the transport trough and the horizontal long plate is not less than 15 degrees.
[0013] Furthermore, a turbine sand extractor is fixedly installed at one end of the horizontal long plate. The turbine sand extractor includes a sand extractor housing. The bottom of the sand extractor housing has a sand inlet and the top of the rear has a sand outlet. The sand outlet is connected to the sand inlet end of the transport trough. A wheel is mounted on a bearing at the center of the sand extractor housing. Multiple sand extractor blades are fixed on the wheel at intervals. The sand extractor blades are used to push the sand from the sand inlet to the sand outlet when the wheel rotates.
[0014] Furthermore, the power unit and vibration device are installed on the horizontal long plate or the two side plates, and the wheel extends outward through the sand-collecting shell and is connected to the power unit through a belt drive assembly.
[0015] Furthermore, a connector is provided between the vibration device and the transport trough. The connector is a rigid connector, an elastic connector, a hinged connector, or a composite connector bracket, used to transmit the vibration generated by the vibration device to the transport trough.
[0016] A method for filling sandbags using the sandbag filling machine according to any one of claims 1 to 9 includes the following steps:
[0017] S1: Set the sandbag opening at the sand inlet end of the transport trough, and use the sandbag fixing structure to clamp the edge of the bag opening to open the bag opening; the sandbag as a whole is laid out backward along the bag body guide space inside the transport trough so that the bag body is without wrinkles, bends and blockages;
[0018] S2: The whole machine is moved by the traction device so that the sand inlet at the bottom of the turbine sand extractor is in contact with the surface sand to achieve sand intake or movement. During the process, the sand is shoveled into the sandbag through the horizontally set transport trough and reaches the sandbag opening to achieve sand intake.
[0019] S3: The vibration force of the vibration device is transmitted to the transport trough; the transport trough drives the sandbags and sand inside to vibrate synchronously and slide into the depth of the sandbags.
[0020] The beneficial effects of this invention are as follows:
[0021] This invention sets the sandbag fixing structure at the sand inlet end, so that the opening of the slender sandbag can be fixed and opened, reducing the need for continuous manual bag opening.
[0022] This invention allows the operator to pull the sandbag filling machine along the sand surface at the sand inlet, enabling the equipment to directly utilize the sand on site to complete sand extraction and feeding during the movement, reducing the need for manual sand shoveling and delivery.
[0023] This invention applies a synthetic excitation force with a length component to the transport trough through a vibration device, causing the sand entering the bag opening to migrate from the sand inlet traction end to the power end, reducing siltation and blockage at the bag opening and improving the continuous filling efficiency of slender sandbags.
[0024] This invention integrates a sand extractor that is flush with the horizontal long plate at the front end of the transport trough. During the equipment's traction movement, the sand extractor blades directly scrape sand from the ground, extracting it as it moves and supplying it on-site. No manual assistance is required for feeding, thus reducing the intensity of manual labor.
[0025] The present invention arranges the transport trough and the horizontal long plate at an angle, relying on gravity to form the basic sand transport trend; with the addition of a vibration device to transmit periodic vibration to the trough, the combined effect of gravity and vibration inertia drives the sand to migrate into the depth of the bag, thereby solving the problem of sand accumulation and blockage at the mouth of the slender sandbag.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] Example 1
[0041] Please refer to Figures 1 to 3 , Figures 9 to 11This embodiment discloses a sandbag filling machine, which mainly includes a horizontally arranged transport trough 1, a vibration device 3, a power device 2, a sandbag fixing structure 4, and a traction device 5. The vibration device 3 is installed on the top of the transport trough 1 and directly connected to the transport trough 1. The power device 2 is also mounted on the top of the transport trough 1, and the power device 2 and the vibration device 3 are connected by transmission. The power device 2 outputs power to drive the vibration device 3 to generate periodic excitation force. The excitation force acts directly on the inside of the transport trough 1, pushing the sand in the trough to continuously migrate to the bottom of the sandbag.
[0042] Specifically, such as Figure 2 As shown, the transport trough 1 extends along its own length, and the internal space is used to support and guide the slender sandbags; one end of the transport trough 1 is the sand inlet end 6, and the sandbag fixing structure 4 is set at the sand inlet end 6 to open and lock the sandbag mouth; the traction device 5 is simultaneously set at the end of the transport trough 1, so that the operator can drag the whole machine to slide and walk on the sand.
[0043] Please refer to this as well. Figure 2 The sandbag fixing structure 4 can be selected from any one of the following: clamp, clip, pressure plate, elastic clamp, or bolt clamp. In this embodiment, an elastic clamp is used. The elastic clamp consists of two sets of symmetrical semi-circular metal plates and an elastic rod. The semi-circular metal plates are installed inside the transport trough 1 by the elastic rod. Under normal conditions, the elastic rod continuously pushes the two metal plates outward, keeping them in a spread-out state away from each other. During operation, the two metal plates are manually pressed inward to cover the sandbag opening on the outside of the metal plates. After releasing, the rebound force of the elastic rod opens the bag opening and presses the edge of the bag opening tightly against the inner wall of the side plate 102 of the transport trough 1, fixing the sandbag opening to the sand inlet end 6 of the transport trough 1. This can be used to ensure that the sand enters the bag smoothly.
[0044] Please refer to this as well. Figure 2 , Figure 3 The vibration device 3 uses a dual-shaft box-type eccentric vibrator. Its internal meshing gears, eccentric shaft, and eccentric block structure are mature existing linear vibration technologies, which will not be elaborated here. The power unit 2 uses a gasoline engine, but can also be replaced with a diesel engine. The vibration device 3 establishes a transmission connection with the power unit 2 through a belt drive assembly 7, such as... Figure 2 As shown, the transmission structure is as follows: the output shaft of the gasoline engine and one of the eccentric shafts of the dual-shaft box-type vibrator are respectively fixed with synchronous pulleys on the same axis. The two sets of synchronous pulleys are connected by a closed-loop transmission via a synchronous belt to achieve synchronous power output.
[0045] Please refer to this as well. Figure 2The transport trough 1 has an open U-shaped structure, including a bottom plate 101 and side plates 102 symmetrically fixed on both sides of the bottom plate 101. The bottom plate 101 and the side plates 102 together form a closed bag guiding space 103, which is used to lay and limit the slender sandbags, preventing the bags from shifting laterally or wrinkling. The lower surface of the bottom plate 101 is a complete surface, which directly forms the sand sliding contact surface, allowing the sandbags to slide on the soft sand surface without the need for rollers.
[0046] like Figure 2 As shown, the traction device 5 is a double-bar traction handle, which is fixed to the outer wall of the side plates 102 on both sides of the transport trough 1 respectively; the operator holds the traction handle and drags the whole machine along the sand, and the sand passes through the sandbag fixing structure 4 and enters the bag.
[0047] During operation: the power unit 2 drives the dual-shaft box-type vibrator to operate synchronously. The two eccentric shafts rotate synchronously in opposite directions. The vertical components of the centrifugal force generated by the eccentric blocks cancel each other out, while the horizontal conveying components along the length of the trough are superimposed in the same direction, generating a directional reciprocating excitation force along the direction of the transport trough 1. The vibration is directly transmitted to the sand and sandbags in the trough. Relying on the vibration inertia, the sand is continuously pushed to slide into the depth of the sandbags, completely replacing the manual process of repeatedly shaking and patting the bags to loosen the material, thereby avoiding the accumulation and blockage of sand at the bag opening.
[0048] Example 2
[0049] Please see Figures 4 to 8 This embodiment adds a sliding support base, an automatic sand-collecting mechanism, an inclined sand-transporting structure, and a split vibration transmission structure to the structure of embodiment 1. The core improvements are as follows: a support body 8 is added, which is a whole horizontal long plate 81; the direct sliding structure of the transport trough 1 is eliminated, and the bottom surface of the horizontal long plate 81 is used as the sliding contact surface of the whole machine; the transport trough 1 is inclined and erected above the horizontal long plate 81, and the angle of inclination between the transport trough 1 and the horizontal long plate 81 is ≥15°. The sand inlet end 6 of the transport trough 1 is located at the high inclined position, and gravity provides the basic power for the sand to slide downward, accelerating the transport of sand into the sandbag; in this embodiment, the power device 2 and the vibration device 3 are uniformly assembled on the horizontal long plate 81.
[0050] like Figure 5 , Figure 7 As shown, to match the automatic feeding requirements of the high-level sand inlet 6, a turbine sand extractor 9 is fixedly installed at the front end of the horizontal long plate 81. The turbine sand extractor 9 includes a volute-shaped sand extractor housing 91, with a sand inlet 92 at the bottom and a sand outlet 93 at the upper rear of the housing. The sand outlet 93 is seamlessly connected to the high-level sand inlet 6 of the transport trough 1. The shaft of the sand extractor housing 91 is rotatably mounted with a wheel 94 via bearings. Multiple sand extractor blades 95 are fixed at intervals around the outer circumference of the wheel 94. When the wheel 94 rotates, the sand extractor blades 95 lift and convey the sand from the bottom sand inlet 92 to the top sand outlet 93.
[0051] See details Figure 7 Here, the bottom sand inlet 92 of the turbine sand extractor 9 is flush with the bottom surface of the horizontal long plate 81. The weight of the whole machine causes the horizontal long plate 81 to sink slightly and fit the sand surface, and the loose floating sand on the surface automatically flows into the sand inlet 92. When the wheel 94 continues to rotate, the sand-collecting blades 95 circulate and grab the sand, automatically convey it upward and throw it into the inclined transport trough 1 at the rear. The whole process does not require manual shoveling of sand.
[0052] like Figure 5 As shown, in this embodiment, both the power unit 2 and the vibration unit 3 are installed on the top surface of the horizontal long plate 81; the vibration unit 3 is still driven by the power unit 2 through the belt drive assembly 7. One end of the wheel 94 of the turbine sand extractor 9 extends outward through the sand extraction shell 91 and is connected to the power unit 2 through the belt drive assembly 10; the power unit 2 is a gasoline engine or a diesel engine, and the transmission structure is as follows: the engine output shaft and the outer end of the wheel 94 are respectively coaxially fixed with synchronous pulleys, and the two sets of synchronous pulleys are driven by synchronous belts, and a single power source synchronously drives the vibration and sand extraction mechanisms.
[0053] like Figure 5 As shown, in this embodiment, since the vibration device 3 and the inclined transport trough 1 are separate and have no direct rigid connection, a connector 11 is added between them to ensure stable vibration transmission. The connector 11 can be any one of a rigid connector, an elastic connector, a hinged connector, or a composite connector bracket, used to stably transmit the excitation force generated by the vibration device 3 to the inclined transport trough 1. Figure 5 As can be seen from the diagram, this embodiment uses a rigid connector to transmit vibration.
[0054] A method for filling sandbags with a sandbag filling machine
[0055] How to use Example 1:
[0056] S1: Align the opening of the long sandbag with the sand inlet end 6 of the transport trough 1, press the semi-circular metal piece of the sandbag fixing structure 4, put the bag on, and then release the elastic clamp. Rely on the elastic rebound force to open and lock the bag opening; lay the main body of the sandbag flat and spread it out along the bag body guide space 103 of the transport trough 1 to eliminate the wrinkles and bends of the bag body and avoid filling blockage.
[0057] S2: The operator holds the traction handle of the traction device 5 and drags the whole machine along the sand. The U-shaped transport trough can scrape the surface sand and enter through the sand inlet 6, and then pass through the open bag mouth into the sand bag.
[0058] S3: Start the power unit 2. The power drives the dual-axis vibrator through the belt drive assembly 7. The directional vibration force is transmitted to the horizontal transport trough 1. The trough drives the sand and sandbags inside to vibrate synchronously. Relying on the vibration inertia, the sand is continuously pushed to slide into the depth of the sandbag. There is no sand accumulation at the bag opening and no need for manual shaking of the bags. The whole machine continues to slide until the sandbag is completely filled, then the machine stops and the empty bags are replaced.
[0059] Usage method of Example 2
[0060] S1: Lock the mouth of the sandbag to the high sand inlet end 6 of the inclined transport trough 1 through the sandbag fixing structure 4, and lay the bag body down along the inclined trough.
[0061] S2: The operator holds the traction handle and drags the horizontal long plate 81 to the sand-filling area so that the sand inlet 92 at the bottom of the turbine sand extractor 9 fits against the surface sand; the power unit 2 is started, and the single power source outputs two power sources simultaneously. One power source drives the dual-shaft eccentric vibration device 3, and the other power source drives the internal wheel 94 of the turbine sand extractor 9 to rotate through the belt drive assembly 2 10.
[0062] S3: The machine is dragged along the sand at a constant speed. The weight of the equipment causes the horizontal plate 81 to sink slightly, and the surface sand automatically flows into the sand inlet 92, which is flush with the bottom plate 101. The rotating sand-grabbing blades 95 continuously grab the sand and lift it upwards, and automatically send it from the sand outlet 93 into the high sand inlet end 6 of the inclined transport trough 1.
[0063] S4: Vibration device 3 transmits directional excitation force to inclined transport trough 1 through connector 11; the sand material is simultaneously subjected to the downward gravity component along the trough and the vibration inertial thrust in the trough, continuously and evenly migrating into the depth of the sandbag, breaking up the clumps of sand and solving the problem of siltation at the bag opening; the whole machine moves forward continuously to achieve continuous automatic filling, and after the sandbag is filled, the power source is turned off and the empty bag is replaced for cyclic operation.
[0064] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
