Description

Technical Field

[0001] The invention relates to the technical field of sand fixation and control, and in particular to a device for continuously deploying sandbags on the surface of sand particles and a sandbag fixation method. Background Art

[0002] Existing sand fixation methods include laying sand barriers to reduce the flow of sand, and using firewood, straw, clay, branches, laths, pebbles and other materials to make barriers on the sand surface, which can reduce wind speed and fix the sand surface.

[0003] Chinese patent CN202410314501.0 discloses a sand-fixing device that relies on sand barrier engineering to carry out sand-fixing work. The device can reduce the use of manpower to complete the engineering task of sand barrier layout, and can reduce the damage caused by wind and sand to plants during intermittent wind and sand activities. The device moves the hay in the hay box to the bottom of the bracket through the work of the transmission component and cooperates with the tractor to drive the frame to move, and finally drives the pressure rod on the frame to rotate up and down under the rotation of the turntable to complete the entire sand barrier engineering task. In addition, biological sand fixation is also a very effective way to fix sand, also known as plant sand fixation. It is a technical measure to prevent and control deserts, stabilize oases, and improve the environmental quality and production potential of sandy areas by means of cultivating and planting plants. First, the forward movement of quicksand and wind erosion hazards are controlled, and the flat land between hills protected by vegetation may be opened up as farmland, orchards, melon fields or forage bases, which can provide an appropriate amount of plant resources. The main difficulty of this sand-fixing method is that the successful planting of sand-fixing plants is difficult to complete;

[0004] Chinese patent CN202410100585.8 discloses a wind-proof and sand-fixing device, which is mainly aimed at the technical problem of obstructed root growth of sand-fixing plants. The device is attached to the surface of the desert through a bottom plate, and spiral blades, water injection pipes, pull rods, water tanks and other devices are arranged on the bottom plate. The spiral blades are designed to increase the friction area with the sand, thereby enhancing stability to achieve the purpose of promoting the growth of sand-fixing plants. Another effective way to fix sand is to lay grass grids. Grass grids are a method of preventing wind and sand, conserving water, and building grass grids into miniature protective belts in the desert. Laying grass grids can increase the roughness of the surface, reduce the sand transport capacity of the airflow, and reduce the evaporation of water on the sand surface;

[0005] Chinese patent CN202210984657.0 discloses a device and method for laying grass grids horizontally for sand fixation machines, and the device includes a grass feeding mechanism, a grass cutting mechanism, etc., which can improve the stability of the grass grids after laying and play the effect of avoiding sand plowing. However, at present, the laying of grass grids is still generally done manually, and mechanization has not been widely carried out, and the efficiency is difficult to effectively improve. In addition, due to the remote work location, harsh environment, high labor intensity, and the grass required for sand fixation needs to be transported from a distance, resulting in very low efficiency and extremely high cost, and there is a lack of mature and effective laying machines in this work. In summary, in the prior art, the manual laying of grass grids for sand fixation has high labor intensity and low work efficiency, and is not suitable for large-scale sand fixation; and when using machines to lay grass grids for sand fixation, the sand fixation materials usually need to be transferred from a distance, which is inefficient, and is limited by factors such as cost and reliability. There is no simple and efficient machine for laying grass grids on the market; the present invention proposes the use of sandbags instead of grass for laying, and the sand fixation raw materials are locally sourced, which can achieve sand control with sand and greatly reduce the cost of sand fixation. At the same time, the device and method can significantly improve the degree of mechanization and work efficiency. Summary of the invention

[0006] In order to overcome the defects of the above prior art, the present invention provides a device for continuously deploying sandbags on the surface of sand particles and a sandbag sand fixation method, which improves the degree of mechanization and work efficiency. In addition, the present invention uses sandbags instead of grass for laying, and the sand fixation raw materials are locally sourced, sand is used to fix sand, which greatly reduces the cost of sand fixation, has important engineering application significance, and is expected to generate huge economic value.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A device for continuously deploying sandbags on the surface of sand particles, comprising: a sand inlet trough 1, a bag material feeder 20 that continuously feeds thin bag materials for forming sandbags into the sand outlet of the sand inlet trough 1, a sandbag sealer 30 that seals the thin bag materials carrying sand to form long strip sandbags 90, and a sandbag deployer 40 that arranges the long strip sandbags 90 in a certain shape on the surface of sand particles through movement. The sand inlet trough 1, the bag material feeder 20, the sandbag sealer 30 and the sandbag deployer 40 are all carried by a frame 50 and move together. The sand inlet of the sand inlet trough 1 is lower than the surface of the sand particles, so that the sand particles are moved during the movement of the sand inlet trough 1. The sand particles enter the sand inlet 1 from the sand inlet 2, and due to the continuous advancement of the sand inlet 1, they rise along the sand trough pipe 3 and move backward to the sand outlet 4, and then accumulate on the thin bag material, and move backward in the sandbag sealing machine 30 together with the thin bag material. During the backward movement of the thin bag material, both sides move upward and are rolled up on both sides, so that the accumulated sand particles are also wrapped in the thin bag material. At the same time, the two sides of the rolled-up thin bag material overlap and are sealed by the sandbag sealing machine 30 to form a long sandbag 90. Finally, the long sandbag 90 enters the sandbag deployer 40 and is deployed on the surface of the sand particles by swinging to form a grid-like sandbag coverage.

[0009] The sand inlet trough 1 includes a spiral feeder 8 inside, so that the sand entering the sand inlet can rise and move backward in the sand trough pipe 3 more effectively.

[0010] The sandbag sealer 30 performs transverse sealing at regular intervals while sealing along the longitudinal direction, thereby forming periodic transverse sealing on the long sandbag 90, which is beneficial for swinging and deploying the long sandbag 90 during the swinging process of the sandbag deployer 40.

[0011] The width of the thin bag material is greater than the width required to form a sandbag, and the longitudinal sealing portion is only a portion of the thin bag material, and the remaining thin bag material is erected above the sandbag to slow down the wind speed behind the sandbag.

[0012] The edge of the thin bag material is non-linear, thereby reducing the probability of the thin bag material being blown down by the wind.

[0013] The shapes of the sandbags deployed by the sandbag deployer 40 include square, prism, rectangle, hexagon and the like.

[0014] A frame 50 includes a plurality of sand feeding troughs 1 , a bag material feeder 20 , a sandbag sealing machine 30 and a sandbag deployer 40 .

[0040] The bag material feeder 20 includes a bag material frame 16, on which a bearing 18 and a bag material shaft 22 are arranged, and a thin bag material roll 24 is arranged on the bag material shaft 22. A guide slide 42 is installed on the side wall of the sand separation groove 14, and a closing ring 46 is arranged around the outer side of the sand outlet 4.

The cylinder 86 drives the guide closing groove 78 through the connecting rod 84 to complete the change of the direction of the long strip sandbag 90.

[0045] The edge of the thin bag material is a thin bag material edge 92 , and the thin bag material edge 92 is non-linear, such as a sawtooth shape.

[0046] A sand fixation method of continuously deploying sandbags on the surface of sand particles comprises the following steps;

[0047] When the device is in the first mode, when the sand inlet trough 1 is pulled forward by the pulling device, since the sand inlet 2 of the sand inlet trough 1 is lower than the surface of the sand particles, the sand particles will enter the sand trough pipe 3 from the sand inlet 2 due to the extrusion effect when the sand inlet trough 1 moves forward;

[0048] Thus, during the movement of the sand inlet trough 1, the sand enters the sand inlet trough 1 from the sand inlet port 2, and due to the continuous advancement of the sand inlet trough 1, the sand rises along the sand trough pipe 3 and moves backward to the sand outlet 4 for discharge;

[0049] Then, the sand is accumulated on the thin bag material and moves backward in the sandbag sealing machine 30 together with the thin bag material. During the backward movement of the thin bag material, both sides move upward and are rolled up, and the sand particles are also wrapped in the thin bag material. At the same time, both sides of the rolled-up thin bag material overlap and are sealed by the sandbag sealing machine 30 to form a long strip sandbag 90.

[0050] Finally, the long sandbags enter the sandbag deployer 40 and are deployed on the surface of the sand particles by swinging to form a grid-like sandbag coverage.

[0051] Furthermore, after the sand is discharged from the sand outlet 4, the bag material feeder 20 transports the thin bag material to the bottom of the sand outlet 4, so that the sand discharged from the sand outlet 4 falls in the middle of the thin bag material and moves backward in the sandbag sealing machine 30 together with the thin bag material. During the movement, the thin bag material is gradually rolled up on both sides under the action of the closing baffle 38, and the sand is also wrapped in the thin bag material;

[0052] The thin bag material wrapped with sand enters the conveying mechanism 36, and is driven by the conveying mechanism 36 to continuously move forward and pass through the longitudinal ultrasonic welding machine 62. The longitudinal sealing wheel 58 and the longitudinal welding plane 68 of the longitudinal ultrasonic welding machine 62 weld the overlapping thin bag materials together to complete the longitudinal sealing of the sandbag; then, the thin bag material passes through the transverse ultrasonic welding machine 64, and the transverse welding pressing block 72 of the transverse ultrasonic welding machine 64 is driven by the screw rod 74 to press against the transverse welding platform 66 to complete the transverse sealing of the sandbag;

[0053] Finally, a long strip sandbag 90 is formed; the transverse ultrasonic welding machine 64 is used to periodically perform transverse sealing at regular intervals, and finally a segmented long strip sandbag 90 is formed.

[0054] When the device is in the first mode, when the sand inlet trough 1 is pulled forward by the traction device, since the sand inlet 2 and the sand shovel 6 of the sand inlet trough 1 are lower than the surface of the sand particles, the sand particles will first be gathered at the sand inlet 2 by the sand shovel 6 when the sand inlet trough 1 moves forward, and enter the sand trough pipe 3 from the sand inlet 2 due to the extrusion effect, and the sand particles will rise and move backward along the sand trough pipe 3 to the sand separation trough 14 under the action of the spiral feeder 8, and then the sand particles will be discharged from the sand outlet through the sand separation trough 14;

[0055] The rolled thin bag material roll 24 is fixed on the bag material frame 16 through the bag material shaft 22 and the bearing 18. One end of the thin bag material passes through the guide slide 42 and then enters the closing ring 46. At this time, the two sides of the thin bag material are gradually rolled up. At the same time, as the thin bag material continues to move downward, the two sides of the rolled thin bag material overlap together under the action of the closing chute 44, and enter the next stage to wait for the arrival of sand to complete the sealing and packaging together; the two sides of the rolled thin bag material from the bag material feeder 20 overlap together under the action of the closing chute 44, pass through the longitudinal ultrasonic welding machine 62, and complete the longitudinal sealing of the thin bag material under the action of the longitudinal sealing wheel 58 and the longitudinal welding plane 68, and then continue to pass downward through the transverse ultrasonic welding machine 64, and the screw rod 74 drives the transverse welding pressing block 72 to squeeze the transverse welding plane 66 with the thin bag material to complete the transverse welding of the thin bag material. At this time, the sand outlet 4 is opened, and the sand enters the thin bag material that has sealed the lower end. When the sand accumulates to a certain height and the segment of the formed long sandbag 90 reaches a predetermined length, the transverse ultrasonic welding machine continues to work to seal the upper end of the thin bag material to form a complete segment of the long sandbag 90. The work of the sandbag ultrasonic welding machine is repeated in this way.

[0056] Beneficial effects of the present invention:

[0057] Traditional laying of grass grids mainly relies on manual labor, which is inefficient and low-cost. In addition, the raw materials for sand fixation are not locally available, but often need to be transferred from a distance, further increasing the cost of sand fixation. The device for continuously deploying sandbags on the surface of sand particles provided by the present invention adopts the method of using sand to control sand, uses local materials, and packs sand particles in thin bags to form long sandbags, which are then deployed on the surface of sand particles to form a grid-like sandbag cover, thereby reducing the flow of sand particles and achieving windproof and sand fixation. At the same time, the device has a simple and reliable structure, low implementation cost, and can be fully automated, which can effectively reduce the cost of sand fixation and improve the efficiency of sand fixation.

[0058] The invention can be used to automatically and continuously deploy a layer of long strip sandbags on the surface of a desert in a certain shape such as a grid shape, and the long strip sandbags in the grid shape play a role in fixing sand like grass grids.

[0059] The device for continuously deploying sandbags moves forward under the traction of the traction device through the sand inlet below the surface of the sand grains, so that the sand grains rise and move backward along the sand trough pipe connected to the sand inlet to the sand outlet to be discharged, and then the sand grains are accumulated on the thin bag material and move backward in the sandbag sealing machine together with the thin bag material. The thin bag is rolled up on both sides by the closing mechanism, and the sand grains are wrapped in the thin bag, and the sand grains continue to move backward with the thin bag material. The two sides of the gradually rolled up thin bag material overlap longitudinally and are sealed by the ultrasonic welding machine to form a long strip of sandbags. Finally, the long strip of sandbags continues to move backward into the sandbag deployer, and is swung in the sandbag deployer and deployed on the surface of the sand grains to form a grid-like sandbag cover, ultimately achieving the purpose of windproof and sand fixation.

[0060] The sandbag sealing machine performs transverse sealing at regular intervals while sealing along the longitudinal direction, thereby forming periodic transverse sealing on the long strip of sandbags, which is conducive to the swing deployment of the sandbag deployer.

DETAILED DESCRIPTION

[0076] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0077] The present invention discloses a device for continuously deploying sandbags on the surface of sand particles. The specific steps of a method for using the device to continuously deploy sandbags on the surface of sand particles are as follows:

[0078] 1. Collecting sand and transporting it

[0079] like Figure 1 As shown, the device 10 for continuously deploying sandbags on the surface of sand particles includes four main components, namely a sand inlet trough 1, a bag material feeder 20, a sandbag sealer 30 and a sandbag deployer 40, all of which are supported by a frame 50 and move together as a whole.

[0080] Usually, the device itself does not need a power device, and its movement comes from a traction device. The traction device can be a tractor, an automatic moving machine, an unmanned tractor, or other powered machines. In a broad sense, the traction device can also be used as a part of the frame 50, that is, a frame with a power device. The sand inlet 1 includes a sand inlet 2, a sand trough pipeline 3, and a sand outlet 4.

[0081] When the sand inlet 1 is pulled forward by the traction device, the sand inlet 2 of the sand inlet 1 is lower than the surface of the sand particles, and the sand particles will enter the sand trough pipe 3 from the sand inlet 2 due to the extrusion effect when the sand inlet 1 moves forward. And due to the continuous advancement of the sand inlet 1, the sand particles rise and move backward along the sand trough pipe 3 to the sand outlet 4 to be discharged. The sand flow rate of the sand outlet 4 is generally determined by the sand bag packing rate. By adjusting the degree to which the sand inlet is lower than the sand surface, the speed at which the device 10 advances, or the diameter of the sand inlet pipe 3, etc., the sand flow rate of the sand outlet 4 can be adjusted to a degree that adapts to the sand bag packing rate.

[0082] The control process of the discharged sand flow rate can be achieved by automatic control through an integrated sensor or by manual control under a remote wireless signal.

[0083] The sandbag sealer 30 seals the sandbag longitudinally and performs transverse sealing at regular intervals, thereby forming periodic transverse seals 96 on the long sandbag, which facilitates the sandbag deployer 40 to bend the long sandbag 90 left and right during the swinging process, thereby forming a grid shape. The sandbag sealer 30 uses ultrasound to seal. Other sealing methods can also help achieve the purpose of the device, such as needle sewing sealing, adhesive sealing, nail sealing, etc.

[0084] The main function of the sandbag deployer 40 is to give a lateral reciprocating load to the elongated sandbag 90 that moves continuously backward, so that the elongated sandbag 90 can move forward and reciprocate left and right on the surface of the sand at the same time, and can form a predetermined grid according to the set movement program to achieve a predetermined deployment effect 100; the shape of the sandbag after being deployed by the sandbag deployer 40 includes squares, prisms, rectangles, hexagons, etc.

[0085] The swing of the sandbag deployer 40 is determined by the mechanical vibration cycle of the mechanical device itself and the moving speed of the frame. A spring or other energy storage mechanism can be arranged in the swing mechanism, so that the period of the lateral reciprocating motion of the sandbag deployer 40 can be affected by the spring, and has its own intrinsic resonance frequency and period, so that only a small amount of energy needs to be applied to achieve the required lateral reciprocating motion speed. In addition, the stiffness of the spring can be set to be adjustable, for example, by adjusting the length or preload, so that the reciprocating motion period and amplitude of the swing mechanism can be adjusted as needed, thereby controlling the grid shape of the final sandbag deployment.

[0086] The swing of the sandbag deployer 40 is controlled by an electromechanical control device. If the cost permits, the implementation of the present application can be achieved by using a fully electrically controlled device to achieve controllable swing.

[0087] The width of the thin bag material is usually larger than the width required to form the sandbag. The longitudinal seal 94 is only part of the thin bag material. The remaining thin bag material is erected above the sandbag after the sandbag is deployed to slow down the wind speed behind the sandbag. The edge of the thin bag material is non-linear, such as a sawtooth shape. Therefore, after the long strip sandbag 90 is formed, the remaining thin strip material is erected to form a sawtooth wind-blocking and energy-dissipating structure, thereby reducing the probability of the erected thin bag material being blown down by the wind. Other shapes such as wave shape, square wave shape, etc. also belong to the scope of the present application.

[0088] like Figure 2 As shown, another implementation of the device 10 for continuously deploying sandbags on the surface of sand grains also includes four main components, namely, a sand inlet trough 1, a bag material feeder 20, a sandbag sealer 30 and a sandbag deployer 40, and all are carried by a frame 50' and move together. The sand inlet trough 1 includes a sand inlet 2, a sand trough pipeline 3, a sand outlet 4, a sand shovel 6, a spiral feeder 8, a motor 12, and a sand distribution trough 14.

[0089] When the sand inlet 1 is pulled forward by the traction device, since the sand inlet 2 and the sand shovel 6 of the sand inlet 1 are lower than the surface of the sand particles, the sand particles will first be gathered at the sand inlet 2 by the sand shovel 6 when the sand inlet 1 moves forward, and enter the sand trough pipeline 3 from the sand inlet 2 due to the extrusion effect, and the sand particles rise and move backward along the sand trough pipeline 3 to the sand dividing trough 14 under the action of the spiral feeder 8, and then the sand particles are discharged from the sand outlet through the sand dividing trough 14. Among them, the flow rate of sand particles discharged from the sand outlet 4 can be controlled by the forward speed of the traction device, the height of the sand shovel 6 below the surface of the sand particles, the speed of the motor 12 on the spiral feeder, and the sand dividing trough valve (not shown). The control process of the discharge sand flow rate can be realized by automatic control by an integrated sensor or manual control under a remote wireless signal. The device for moving the sand particles upward and backward inside the sand trough pipeline 3 is not limited to the spiral feeder 8. Any device that can realize the upward and backward transportation of sand particles, such as a belt conveyor, a belt conveyor with a baffle, etc., can be used as a feasible implementation method of the present invention.

[0090] 2Pack and seal the sand into long strips of sandbags

[0091] After the sand is discharged from the sand outlet 4, the bag material feeder 20 transports the thin bag material to the bottom of the sand outlet 4, so that the sand discharged from the sand outlet 4 falls in the middle of the thin bag material and moves backward in the sandbag sealing machine 30 together with the thin bag material. During the movement, the thin bag material is gradually rolled up on both sides under the action of the closing baffle 38, and the sand is also wrapped in the thin bag material.

[0092] As the thin bag material continues to move backward, the rolled thin bag material overlaps on both sides. Then, the sandbag sealer 30 is passed through, wherein the longitudinal ultrasonic welding machine 62 performs longitudinal sealing, and finally forms a long strip sandbag 90.

[0093] On this basis, a transverse ultrasonic welding machine 64 can be used to periodically perform transverse sealing at regular intervals, and finally form a segmented long strip sandbag 90. The sealing machine is preferably an ultrasonic welding machine, and other sealing machines such as needle sewing sealing machines, adhesive sealing machines, and sealing machines using metal nails or other materials can also achieve the sandbag sealing in this application.

[0094] Another implementation method is that after the sand is discharged from the sand outlet 4, the bag material feeder 20 transports the thin bag material to the front side of the sand outlet 4, and through the action of the closing ring 46, the two sides of the thin bag material are rolled up. At the same time, as the thin bag material continues to move downward, the two sides of the rolled thin bag material overlap together under the action of the closing chute 44, and then pass through the sandbag sealing machine 30, wherein the longitudinal ultrasonic welding machine 62 performs longitudinal sealing, and the transverse ultrasonic welding machine 64 periodically performs transverse sealing, and finally a long strip of sandbag 90 is formed.

[0095] 3. Deploy Sandbags

[0096] The long strip sandbag 90 formed after packing and sealing finally passes through the sandbag deployer 40, and is about to be away from the device 10 and deployed on the sand surface in a certain shape due to the lateral left and right swing of the sandbag deployer 40. Usually, the sandbag deployer 40 is guided by the closing groove 78 under the traction of the cylinder 86 and the connecting rod 84, and the long strip sandbag 90 is deployed on the sand surface in a predetermined shape.

[0097] These shapes include but are not limited to squares, diamonds, hexagons, etc. The shape of the deployment depends on the expansion and contraction cycle of the cylinder and the periodicity of the transverse sealing of the transverse ultrasonic welder 64. The sandbag deployer 40 may include a spring component for storing energy, so that the swing mechanism has an intrinsic reciprocating motion cycle and frequency. Then, only a small amount of disturbance energy needs to be input to allow the sandbag deployer 40 to reciprocate left and right according to a predetermined rhythm or regularity determined by a spring or other mechanism, and to complete the regular disturbance of the long strip sandbag 90 left and right, thereby achieving the deployment in a certain shape.

[0098] Figure 3 The schematic diagram of the bag material feeder of the device for continuously deploying sandbags on the surface of sand grains proposed by the present invention is shown in Figure 1. Since the device is symmetrical on both sides, only one side is used as an example to explain the working principle of the bag material feeder. The thin bag material roll 24 is fixed to the bag material frame 16 through the bag material shaft 22 and the bearing 18. One end of the thin bag material passes through the guide slide 1 26, and then passes through the guide slide 2 28 and the guide slide 3 34 fixed on the guide frame 32 in sequence, and enters the next stage to wait for the arrival of sand grains to complete the sealing and packaging together. The feeding path of the thin bag material has been marked with a black bold arrow in the figure. The function of the guide slide is to enable one end of the thin bag material to smoothly complete the 180-degree turn and smoothly reach the lower end of the sand outlet 4.

[0099] Figure 4 A top view of the working principle of a bag material feeder for a device for continuously deploying sandbags on the surface of sand particles proposed by the present invention. Since the device is an axisymmetric figure, the left-right symmetrical parts all use the same numbering and naming, and will not cause narrative confusion. The same reason will not be repeated below. This figure clearly and intuitively shows the feeding path of thin bag materials. The guide slide 1 26 is placed at a certain angle so that the thin bag materials can bypass the sand outlet 4 when reaching the guide slide 2 28. At the same time, the smooth sand trough pipe 3 is used, that is, the smooth sand trough pipe 3 also participates in the guiding process of the thin bag materials, so that the thin bag materials can transition from the guide slide 1 26 to the guide slide 2 28 more smoothly.

[0100] Figure 5 A schematic diagram of the working mode of the bag material feeder of another implementation mode of the device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. Since the device is bilaterally symmetrical, only one side is taken as an example to explain the working principle of the bag material feeder. The rolled thin bag material roll 24 is fixed on the bag material frame 16 through the bag material shaft 22 and the bearing 18. One end of the thin bag material passes through the guide slide 42 and then enters the closing ring 46. At this time, the two sides of the thin bag material are gradually rolled up. At the same time, as the thin bag material continues to move downward, the two sides of the rolled thin bag material overlap under the action of the closing chute 44, and enter the next stage to wait for the arrival of sand grains to complete the sealing and packaging. The travel path of the thin bag material has been marked with a black bold arrow in the figure.

[0101] Figure 6 The present invention provides a sandbag sealer structure diagram of a device for continuously deploying sandbags on the surface of sand. The thin bag material wrapped with sand enters the conveying mechanism 36, and is driven by the conveying mechanism 36 to continuously move forward through the longitudinal ultrasonic welding machine 62. The overlapping thin bag materials are welded together under the joint action of the longitudinal sealing wheel 58 and the longitudinal welding plane 68 of the longitudinal ultrasonic welding machine 62 to complete the longitudinal sealing of the sandbag. Then, it passes through the transverse ultrasonic welding machine 64, and the transverse welding block 72 of the transverse ultrasonic welding machine 64 is driven by the screw 74 to press against the transverse welding platform 66 to complete the transverse sealing of the sandbag. The conveying mechanism 36 is driven by a motor, a belt or other driving device (not shown in the figure) as a power source to drive the sand and the thin bag material forward. The conveying mechanism 36 is not limited to the one shown in the figure, and other mechanisms that can realize the conveying function can be used as feasible implementation methods of the present invention.

[0102] Figure 7The front view of the sandbag sealer of the device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. The longitudinal ultrasonic welder 62 is mainly composed of a longitudinal sealing wheel 58 and a longitudinal welding platform 68, which is responsible for completing the continuous longitudinal sealing of thin bag materials. The transverse welding block 72, the screw rod 74 and the transverse welding plane 66 constitute the transverse ultrasonic welder 64 to complete the periodic transverse sealing of thin bag materials. In order to make the structure compact, the transverse ultrasonic welder 64 is placed next to the longitudinal ultrasonic welder 62. It is worth emphasizing here that the sandbag sealer (30) is not limited to an ultrasonic welder. Other machines that can complete the sealing of thin bag materials, such as sewing machines or connection methods such as gluing, can be used as feasible implementation methods of the present invention.

[0103] Figure 8 The sandbag sealer structure diagram of another implementation of the device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. The two sides of the thin bag material rolled up from the bag material feeder 20 overlap together under the action of the closing chute 44, and pass through the longitudinal ultrasonic welding machine 62. The longitudinal sealing of the thin bag material is completed under the action of the longitudinal sealing wheel 58 and the longitudinal welding plane 68, and then continue to pass downward through the transverse ultrasonic welding machine 64. The screw rod 74 drives the transverse welding block 72 to squeeze the transverse welding plane 66 with the thin bag material to complete the transverse welding of the thin bag material. At this time, the sand outlet 4 is opened, and the sand enters the thin bag material with the lower end sealed. When the sand accumulates to a certain height and the segment of the long strip sandbag 90 formed reaches a predetermined length, the transverse ultrasonic welding machine continues to work to seal the upper end of the thin bag material to form a complete segment of the long strip sandbag 90. The work of the sandbag ultrasonic welding machine is similar and reciprocating.

[0104] The sealed sandbag enters the conveying mechanism 36 through the guide groove 48, and the sandbag moves forward between the driving wheel 54 and the driven wheel 52. Since the gap between the driving wheel 54 and the driven wheel 52 is smaller than the width of the sandbag, and the driving wheel 54 has power and rotates, the sandbag obtains a forward driving force, and drives the sandbag into the sandbag deployer 40' at a certain initial velocity.

[0105] Fig. 9 This is a front view of the sandbag sealer structure of another implementation of the device for continuously deploying sandbags on the surface of sand particles proposed by the present invention. The acceleration mechanism 56 is composed of the transmission mechanism 36, the driving wheel 54 and the driven wheel 52. Among them, the gap between the driving wheel 54 and the driven wheel 52 can be adjusted according to the width of the sandbag, which can ensure that the sandbag is squeezed to a certain extent and driven, but the gap is not too small to make it difficult for the sandbag to pass through.

[0106] The method of enabling the sandbag to obtain a certain driving force to move forward is not limited to the acceleration method described herein, and other methods that can enable the sandbag to obtain a driving force can be used as feasible implementation methods of the present invention.

[0107] Fig.10 The sandbag deployer structure diagram of the device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. The elongated sandbag 90 which has been sealed and has obtained a certain initial velocity passes through the slide rail 82, and the cylinder 86 drives the guide closing groove 78 through the connecting rod 84 to complete the change of the direction of the elongated sandbag 90. The elongated sandbag 90 which has changed its direction leaves the sandbag deployer 40 at a certain initial velocity under the action of inertia and covers the surface of the sand grains in a predetermined direction. Fig.11 The front view of the sandbag deployer of the device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. A cylinder 86 is connected to two guide closing grooves 78 respectively through two connecting rods 84, so that the deployment of two sandbags in a symmetrical closed pattern can be realized. The guide closing groove 78 is connected to the sandbag deployer frame (76) through the guide closing groove rotating shaft 88, which ensures the smooth rotation of the guide closing groove 78 and does not affect the movement of the elongated sandbag 90 below on the slide rail 82.

[0108] The deployment pattern includes but is not limited to square, rhombus, hexagon, etc. Any other pattern covering the surface of the sand grains that is conducive to slowing down the flow of the sand grains can be used as a feasible implementation method of the present invention. The deployment pattern depends on a variety of factors such as the swing cycle of the cylinder-controlled guide closing groove 78, the length of each section of the long strip sandbag 90 formed by the transverse ultrasonic welding machine 64 transversely sealing the sandbag, and the moving speed of the rack 50.

[0109] Fig.12 The structure diagram of a long sandbag of a device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. The edge 92 of the thin bag material is non-linear, such as serrated, which can slow down the wind speed to a certain extent without causing the long sandbag 90 to be blown by the wind. All shapes of the edge 92 of the thin bag material that can meet the above requirements, such as wavy and square waves, can be used as feasible implementation methods of the present invention. The longitudinal seal 94 and the transverse seal 96 formed by welding the thin bag material with an ultrasonic welding machine wrap the sand grains in the thin bag material, and the thin bag material of the longitudinal seal 94 and the transverse seal 96 and the wrapped sand grains 98 form a segment of the long sandbag 90.

[0110] Fig.13The final deployment effect diagram of a device for continuously deploying sandbags on the surface of sand grains proposed by the present invention. A set of sand inlet trough 1, bag feeder 20, sandbag sealer 30 and sandbag deployer 40 cooperate with each other to form a deployed "W"-shaped sandbag 102. A cylinder 86 is connected to the guide closing groove 78 through a connecting rod 84. By controlling the contraction frequency of the cylinder 86, the swing period of the guide closing groove 78 can be controlled, and then the angle of the long strip sandbag 90 when leaving the device can be controlled, that is, the contraction frequency of the regulating cylinder can be controlled to form a "W"-shaped sandbag 102. Two groups of the above devices cooperate with each other to form two symmetrical "W"-shaped sandbags 102 after deployment to form a complete closed figure, such as a square. A frame can carry multiple groups of sand inlet troughs 1, bag feeders 20, sandbag sealers 30 and sandbag deployers 40, and form multiple square sand grids when they are towed and driven at one time, forming a deployment effect 100 similar to the figure, which can effectively fix sand and control sand with sand, greatly reducing the cost of sand fixation.

[0111] In the process of deploying grid-shaped sandbags to fix sand, the sand inlet trough, bag feeder, sandbag sealer, and sandbag deployer are all carried by a frame and pulled forward by a traction device. The device itself does not need to have a power device, and all power can come from the traction device. The traction device can be a crawler tractor, desert automatic travel equipment, or other powered machines. Of course, the device can also be integrated with the traction device, that is, the frame of the device itself has the ability to move forward autonomously.
