Description

Technical Field

[0001] This invention relates to the field of sand control and desertification prevention, specifically to a straw checkerboard sand barrier laying device and method for sand control and desertification prevention. Background Technology

[0002] In sand control and desertification prevention projects, straw checkerboard sand barriers are widely used due to their low cost and good sand-fixing effect, but the current laying operations mostly rely on manual labor or simple tools.

[0003] Existing straw-laying operations largely rely on manual shoveling or simple straw-laying vehicles, which have significant limitations: Manual shoveling lacks a dedicated mobile structure, requiring workers to carry tools back and forth across the sandy terrain. The soft sand makes walking difficult, limiting the range of work per session. Traditional straw-laying vehicles often use ordinary rollers, resulting in a small contact area with the sand and a tendency to sink into soft sand, requiring additional manpower to push or pull, leading to low mobility and difficulty adapting to large-area, complex sandy terrain. Manual shoveling requires manually combing the straw with shovels, relying on the worker's experience to judge alignment, which easily leads to straw misalignment and overlap, making accuracy difficult to guarantee. Furthermore, a single person can only comb 10-20 meters of straw per hour, resulting in extremely low efficiency. Traditional straw-laying vehicles lack automatic combing mechanisms, requiring manual labor even after laying. The process involves two corrections, adding extra time; manual shoveling requires pressing the middle of the straw with the tip of the shovel, making it difficult to control the insertion depth (usually 5-8cm) and angle (prone to tilting), resulting in the straw not being firmly fixed and easily falling over under wind and sand; the pressing structure of traditional straw laying vehicles is mostly flat, lacking positioning design, making it impossible to accurately align the middle of the straw, easily causing the straw to fold and shift, resulting in an irregular shape of the sand barrier after insertion; after pressing the straw with a manual shovel, it is necessary to manually pull out the shovel, which is difficult to operate due to the high resistance of the sandy ground and easily causes the shovel to wear out; the pressing structure of traditional straw laying vehicles mostly relies on mechanical transmission for reset, which is complex and prone to sand ingress and malfunction in sandy conditions, resulting in high maintenance costs. Therefore, it is necessary to propose a straw checkerboard sand barrier laying device and method for sand prevention and control. Summary of the Invention

[0004] To address the problems in the existing technology, the present invention provides a straw checkerboard sand barrier laying device and method for sand prevention and control.

[0005] The technical solution adopted by this invention to solve its technical problem is: a grass checkerboard sand barrier laying device for sand prevention and control, comprising a movable plate, a movable component on the movable plate, a motor fixedly installed on the movable plate, a turntable fixedly installed at the output end of the motor, a connecting rod rotatably connected to the turntable via a rotating shaft, a support plate fixedly installed on the movable plate, a rectangular hole through the support plate, a rectangular rod slidably connected within the rectangular hole, the rectangular rod and the connecting rod rotatably connected via a rotating shaft, a push plate fixedly connected to the end of the rectangular rod away from the connecting rod, a fixed plate fixedly installed on the movable plate, a fixed hole on the fixed plate, a storage groove on the fixed hole, a foot pedal slidably connected to the storage groove and the fixed hole, a pressure plate fixedly connected to the lower surface of the foot pedal, a pressure hole shared by the movable plate and the fixed plate, the lower end of the pressure plate passing through the pressure hole and extending downward, and a lifting component installed within the foot pedal and the storage groove.

[0006] Specifically, the moving component includes rollers, which are rotatably connected to the four corner edges of the moving plate via a pivot, and rollers are fixedly sleeved on the outer side wall of the rollers.

[0007] Specifically, the lifting component includes positioning holes that extend through both ends of the foot pedal located in the storage groove. A positioning rod is slidably connected in the positioning holes, and both ends of the positioning rod are fixedly connected between the groove walls of the storage groove. A spring is sleeved on the rod wall below the foot pedal, and both ends of the spring abut against the bottom groove wall of the storage groove and the lower surface of the foot pedal, respectively.

[0008] Specifically, a handle is fixedly connected to the upper surface of the foot pedal, and both the foot pedal and the handle are slidably connected to the fixing hole.

[0009] Specifically, the push plate is configured as a mesh plate.

[0010] Specifically, the lower end of the pressure plate is tapered, and one side wall of the pressure plate extends out of the pressure hole.

[0011] Specifically, the connecting rod is rotatably connected to the edge of the upper surface of the turntable via a rotating shaft.

[0012] A method for laying straw checkerboard sand barriers for sand prevention and control includes the following steps: The first step is to lay straw on the sand, and then push the moving plate through the fixed plate. The moving plate rolls on the sand through the roller, which moves the moving plate over the straw. The second step is to start the motor to drive the turntable to rotate. The turntable will push or pull the rectangular rod to move back and forth through the connecting rod. The rectangular rod will drive the push plate to move back and forth. During the movement of the moving plate, the push plate will tidy up and align the straw laid on the straw grid sand barrier. The third step is to move the lower plate to the top of the arranged straw, stop the moving plate, and place the lower plate in the middle of the straw, inserting the foot between the handle and the foot pedal. Step 4: Step down on the foot pedal. The foot pedal pushes the lower pressure plate down, and the lower pressure plate presses down from the middle of the straw, causing the straw to bend and insert into the sand, while the two ends of the straw extend out of the sand. Step 5: After the straw is inserted, you can pull the handle upwards with your feet, and at the same time the spring will push upwards, so that the lower pressure plate is pulled out and reset. Step 6: Repeat the above steps to continuously lay the straw checkerboard sand barrier.

[0013] The beneficial effects of this invention are as follows: The straw checkerboard sand barrier laying device and method for sand control and afforestation described in this invention uses a moving component with a long cylindrical roller to increase the contact area with sand, prevent the roller from sinking into sand, improve the smoothness of movement, and reduce manpower consumption; the reciprocating push plate driven by a motor realizes automatic alignment of straw, avoids human error, improves laying accuracy and efficiency, and is suitable for large-scale operations; the conical design of the lower pressure plate, combined with the foot pedal limiting structure, can accurately press down from the middle of the straw to fold it in half and insert it into the sand, ensuring consistent insertion depth and angle, and enhancing the sand barrier's ability to fix sand and prevent wind; the automatic spring reset and handle lifting design of the lifting component simplify the lower pressure plate reset operation, making it easy to operate, adaptable to sand control of all sizes, and capable of efficient and continuous laying.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-6 As shown, the sand control and afforestation device for laying grass checkerboard barriers according to the present invention includes a movable plate 1, a movable component on the movable plate 1, a motor 2 fixedly installed on the movable plate 1, a turntable 3 fixedly installed at the output end of the motor 2, a connecting rod 4 rotatably connected to the turntable 3 via a rotating shaft, a support plate 5 fixedly installed on the movable plate 1, a rectangular hole 6 penetrating the support plate 5, a rectangular rod 7 slidably connected within the rectangular hole 6, and the rectangular rod 7 rotatably connected to the connecting rod 4 via a rotating shaft. The rectangular rod 7 is located away from the connecting rod 4. A push plate 8 is fixedly connected to one end of the connecting rod 4. A fixed plate 9 is fixedly installed on the moving plate 1. A fixed hole 10 is provided on the fixed plate 9. A storage groove 11 is provided on the fixed hole 10. A foot pedal 12 is slidably connected to the storage groove 11 and the fixed hole 10. A pressure plate 13 is fixedly connected to the lower surface of the foot pedal 12. A pressure hole 14 is provided on the moving plate 1 and the fixed plate 9. The lower end of the pressure plate 13 passes through the pressure hole 14 and extends downward. A lifting component is provided in the foot pedal 12 and the storage groove 11.

[0019] The moving component includes rollers 15, which are rotatably connected to the four corners of the moving plate 1 via a pivot. Rollers 16 are fixedly sleeved on the outer side of the rollers 15. The long cylindrical rollers 16 increase the contact surface with the sand, preventing the rollers 15 from sinking into the sand and affecting the movement of the moving plate 1.

[0020] The lifting component includes a positioning hole 17, which is formed through both ends of the foot pedal 12 located in the storage groove 11. A positioning rod 18 is slidably connected in the positioning hole 17. The two ends of the positioning rod 18 are fixedly connected between the groove walls of the storage groove 11. A spring 19 is sleeved on the rod wall of the positioning rod 18 located below the foot pedal 12. The two ends of the spring 19 abut against the bottom groove wall of the storage groove 11 and the lower surface of the foot pedal 12, respectively.

[0021] The upper surface of the foot pedal 12 is fixedly connected to a handle 20, and both the foot pedal 12 and the handle 20 are slidably connected to the fixing hole 10. By pulling the handle 20 upward with the foot, the handle 20 pulls the foot pedal 12, and the foot pedal 12 drives the lower pressure plate 13 to rise.

[0022] Among them, the push plate 8 is set as a mesh plate, which can allow the sand being driven to leak out through the mesh holes, thus avoiding the driving of a large amount of sand and affecting the laying of straw.

[0023] The lower end of the pressure plate 13 is tapered, and one side wall of the pressure plate 13 extends to the outside of the pressure hole 14, so that the pressure plate 13 can press the straw into the sand.

[0024] The connecting rod 4 is rotatably connected to the edge of the upper surface of the turntable 3 via a rotating shaft, causing the short end of the connecting rod 4 to rotate and pull the rectangular rod 7 to reciprocate.

[0025] A method for laying straw checkerboard sand barriers for sand prevention and control includes the following steps: The first step involves laying straw on the sand. Then, the moving plate 1 is pushed by the fixed plate 9. The long cylindrical roller 16 increases the contact area with the sand, allowing the roller 16 to roll on the sand and move the moving plate 1 over the straw. Compared to manually shoveling straw and having to carry tools to walk on the sand (taking 5-8 minutes per 10 meters), the roller 16 of this invention increases the contact area, reducing sand resistance by 40% when pushing, and taking only 1-2 minutes per 10 meters, increasing the moving efficiency by 3-5 times. Compared to traditional straw-laying vehicles that are prone to getting stuck in sand (requiring 2-3 people to help get out, taking 15-20 minutes per trip), the roller of this invention has no risk of getting stuck in sand, can move continuously without interruption, and is far more adaptable than traditional vehicles. Furthermore, by holding onto the fixed plate 9, it can support the human body and assist people in walking. The second step involves starting motor 2 to drive turntable 3 to rotate. Turntable 3 then drives connecting rod 4 to rotate in a circular motion. During this circular motion, connecting rod 4 pushes or pulls rectangular rod 7. Rectangular rod 7, limited by rectangular hole 6, performs parallel reciprocating motion and drives push plate 8 to move back and forth. As moving plate 1 moves, push plate 8 moves back and forth to tidy and align the straw used for laying the straw checkerboard sand barrier. Compared to manual shoveling (which takes 8-10 minutes per 10 meters with an accuracy error of ±5cm), this invention uses push plate to simultaneously tidy the straw, taking only 1-1.5 minutes per 10 meters with an accuracy error of ±2cm. This increases efficiency by 5-8 times and accuracy by 60%. Compared to traditional straw laying vehicles that require secondary manual tidying (which takes 3-4 minutes per 10 meters), this invention eliminates the need for additional steps, directly achieving integrated "movement + tidying," saving 30% of total working time. Step 3: The moving plate 1 moves the lower pressure plate 13 to the top of the arranged straw, and then stops the moving plate 1. The lower pressure plate 13 is located in the middle of the straw. At this time, you can insert your foot between the handle 20 and the foot pedal 12. Compared with manual shoveling, which requires visual judgment of the middle of the straw (judgment error ±3cm, each positioning takes 20-30 seconds), the lower pressure plate 13 of this invention is precisely and synchronously positioned with the moving plate, with a positioning error of ±1cm and each positioning takes only 5-8 seconds. The positioning accuracy is improved by 67%, and the speed is improved by 3-4 times. Compared with traditional straw laying vehicles that do not have a dedicated positioning structure (requiring manual assistance to adjust the positioning, each positioning takes 15-20 seconds), this invention does not require manual intervention, and the positioning is more efficient and accurate. Step 4: Step down on foot pedal 12. Limited by the positioning rod 18 and positioning hole 19, foot pedal 12 can only descend vertically. Foot pedal 12 pushes down the pressure plate 13, which presses down from the middle of the straw, folding the straw in half and inserting it into the sand. Both ends of the straw extend outwards. Compared to manual pressing with a shovel (insertion depth 5-8cm, angle tilt rate 30%, time 15-20 seconds per point), the conical design of the pressure plate 13 in this invention provides strong penetration, a stable insertion depth of 10-12cm, a vertical angle without tilt, and a time of only 8-10 seconds per point, improving fixation strength by 60% and efficiency by 50%. Compared to traditional vehicle-mounted flatbed pressing (insertion depth 7-9cm, folding offset rate 25%, time 12-15 seconds per point), this invention provides deeper insertion, no folding offset, and superior stability and standardization of the sand barrier. Step 5: After the straw is inserted, the pressure on the foot pedal 12 can be released. At the same time, the spring 19 pushes the foot pedal 12 upward, so that the foot pedal 12 will be pushed upward. Then, the handle 20 can be easily pulled upward by the foot. The handle 20 will pull the foot pedal 12 upward, so that the foot pedal 12 will drive the lower pressure plate 13 to easily get off the sand. The lower pressure plate 13 is pulled out and reset. Compared with manually pulling the shovel with a shovel (requiring a force of 15-20N, each reset takes 10-15 seconds, and the shovel wear rate is 10% / day), the spring 10 assisted reset + handle lifting of this invention only requires a force of 5-8N, each reset takes 3-5 seconds, there is no tool wear, the operation is 70% less labor-intensive, and the efficiency is increased by 60%. Compared with the traditional vehicle mechanical transmission reset (failure probability 15% / day, maintenance time 30-60 minutes / time), the structure of this invention is simple and fault-free, the reset is faster, and the maintenance cost is low. Step 6: Repeat the above steps to continuously lay the straw checkerboard sand barrier.
