Description

Technical Field

[0001] This application relates to the field of sand fixation and afforestation technology, specifically to a connecting device for a brush-shaped straw rope used in sand fixation and afforestation. Background Technology

[0002] Currently, the main material used to stabilize shifting sand in desert areas is ordinary mesh-like straw checkerboard barriers. These are typically made from wheat or rice straw left over after harvesting, laid out in a checkerboard pattern on sand dunes. The straw is then buried 15-20 centimeters deep using a shovel or straw checkerboard machine, with the ends sticking out about 10-20 centimeters above the sand surface. However, due to the harsh natural conditions in desert areas—high daytime temperatures, large diurnal temperature variations, and strong winds—ordinary straw checkerboard barriers usually rot and break down within one to two years, losing their sand-stabilizing effect.

[0003] The applicant's prior application, "A Production Device for Straw Ropes for Sand Control" (application number 2025117438308), includes a straw input structure, a straw strip input structure, a straw strip conveying structure, a snap-fit ​​installation structure, and a traction and torsion structure. The straw input structure provides straws to the straw strip conveying structure, the straw strip input structure provides straw strips to the straw strip conveying structure, the straw strip conveying structure includes an upper conveying structure, a lower conveying structure, and a frame, the snap-fit ​​installation structure is used to fasten the straw strips and straws together with snaps, and the traction and torsion structure is used to torsion the fixed straw strips and straws into a brush shape. Using brush-shaped straw ropes has a better sand-fixing and sand-controlling effect than ordinary straw grid sand barriers.

[0004] However, due to the limited stroke of the traction structure, the produced brush-like straw ropes are typically segmented structures with a length of 5-10 meters. In desert sand fixation operations, it is often necessary to lay continuous straw ropes of tens or even hundreds of meters to form a complete windbreak and sand barrier. To enhance the windproof effect and laying continuity of the brush-like straw ropes, multiple sections need to be connected together during use to improve the overall sand fixation and sand control capabilities. In existing technologies, the connection of brush-like straw ropes mostly relies on manual operation. Operators must hold the rope and tie the ends of two sections together, which is not only inefficient (the average daily connection per person is only 50-80 meters), but also poses a serious safety hazard because the straw stalks are hard and the ends are sharp, making it easy for operators to be cut or punctured by the straw stalks during the binding process. Therefore, there is an urgent need for a structure that can automatically connect brush-like straw ropes together, ensuring a secure connection and safe operation. Summary of the Invention

[0005] To facilitate the connection of brush-shaped straw ropes together, a connection device for sand fixation and afforestation is provided, including a conveyor belt and a connection structure. The connection structure is located between two conveyor belts and includes a connecting frame and an elastic sleeve for connecting two brush-shaped straw ropes together. The connecting frame is connected to a connecting sleeve structure for fitting the elastic sleeve onto the two brush-shaped straw ropes. Two sets of connecting sleeve structures are provided, and the two sets of connecting sleeve structures are located on opposite sides of the two brush-shaped straw ropes respectively.

[0006] Through the above technical solution, the conveyor belt moves the brush-shaped straw ropes to the connecting structure. The connecting structure fits the elastic sleeves onto the ends of the two brush-shaped straw ropes, thereby connecting them. The two sets of connecting structures work simultaneously from both sides of the straw ropes, making the connection of the straw ropes tighter, the force more even, and less prone to damage. Moreover, the entire process is automated, eliminating the need for manual contact with the ends of the straw ropes, avoiding scratches or punctures to operators from the straw stalks, and solving the safety hazards of manual binding. The elastic sleeves are made of elastic rubber material that is resistant to high and low temperatures and anti-aging, adapting to the extreme temperature difference environment of desert areas. Its elastic properties can closely conform to the straw stalk distribution of the brush-shaped straw ropes, maintaining a tight state under the impact of wind and sand, ensuring connection stability, and further enhancing the sand-fixing effect.

[0007] Optionally, the connecting frame is connected to a storage rod, and multiple storage rods are arranged in a circumferential array. Multiple elastic sleeves are fitted on the outside of the storage rods to supplement the elastic sleeves of the connecting structure. The connecting frame is connected to a feeding cylinder, and the piston rod of the feeding cylinder is connected to a push ring, which is slidably connected to the storage rod.

[0008] The above technical solution allows for the storage of multiple tension sleeves by setting up a storage rod, eliminating the need for frequent manual addition of tension sleeves and meeting the requirements of long-term continuous operation. Furthermore, the feeding cylinder pushes the push ring, which in turn pushes the tension sleeve closer to the connecting structure, making it easier for the connecting structure to smoothly place the tension sleeve onto the end of the brush-shaped straw rope, ensuring the continuity of the connection process.

[0009] Optionally, the connecting structure includes a main rod, with multiple connecting rods hinged to the circumferential surface of the main rod. The multiple connecting rods are arranged in a circumferential array on the circumferential surface of the main rod, and the multiple connecting rods are used to fit the tension sleeve on the storage rod onto the end of the grass stalk. One end of the main rod is connected to a push cylinder, and the main rod is connected to the piston rod of the push cylinder.

[0010] Through the above technical solution, the connecting rods can rotate around the hinge axis with the main rod, allowing multiple connecting rods to converge near the storage rod end. A cylinder is then pushed to move the main rod and connecting rods towards the storage rod, inserting the connecting rods into the tension sleeves on the storage rod. Subsequently, the multiple connecting rods near the storage rod end expand the tension sleeves, allowing them to be removed from the storage rod. Then, the cylinder is pushed to move the main rod and connecting rods towards the brush-like straw rope. The multiple connecting rods then converge near the brush-like straw rope end, opening up near the storage rod end. At this point, the tension sleeves on the connecting rods open and move towards the brush-like straw rope end, finally fitting onto it.

[0011] Optionally, the conveyor belt is provided in two sets, which are located on opposite sides of the connecting structure. Each set of conveyor belts includes two conveyor belts, which are located on the left and right sides of the brush-shaped straw rope, respectively. Both conveyor belts are inclined, and multiple baffles are evenly provided on the outer surface of the conveyor belts.

[0012] Through the above technical solution, the two sets of conveyor belts respectively undertake the functions of conveying the straw ropes to be connected and outputting the connected straw ropes, forming a continuous production line; the inclined conveyor belts can use gravity to keep the brush-shaped straw ropes close to the belt surface, avoiding the straw ropes from slipping due to equipment vibration or slight tilting in the desert working environment; the conveyor belts on both sides form a clamping state from the left and right sides of the straw ropes, ensuring that the straw ropes are accurately conveyed in a straight line to the center position of the connecting structure, avoiding conveying deviation; the baffles can limit the brush-shaped straw ropes in sections, preventing the straw ropes from slipping or stacking during the conveying process, ensuring that the ends of each section of straw rope can be accurately aligned, providing precise positioning for subsequent connections.

[0013] Optionally, the connecting frame is connected to two semi-circular shells arranged vertically. The shells have arc-shaped sliding grooves inside and push plates are provided inside the shells. The push plates are slidably connected to the shells through the sliding grooves, and the shells are located between the two sets of conveyor belts.

[0014] With the above technical solution, after the upper and lower semi-circular shells are closed, the connection ends of the two grass ropes can be limited to prevent the grass ropes from shifting during connection. The push plate can drive multiple grass stalks to move together during the movement, and finally stack the multiple grass stalks together so that the elastic sleeve can fit the multiple grass stalks together, making the brush-shaped grass rope connection more stable.

[0015] Optionally, the housing is connected to a drive motor, the output shaft of the drive motor is connected to a drive gear, the drive gear meshes with a drive rack, the drive rack is arc-shaped, and a sliding hole is provided on one side of the housing, and one side of the push plate passes through the sliding hole and is connected to the drive rack.

[0016] Through the above technical solution, the drive motor provides a stable driving force, which drives the push plate to slide smoothly along the slide groove through the gear and rack transmission. The transmission accuracy is high, and the moving distance and force of the push plate can be precisely controlled. The arc-shaped drive rack is adapted to the arc-shaped structure of the shell, ensuring that the sliding trajectory of the push plate is consistent with the circumference of the end of the straw rope. This results in a more uniform gathering effect on the straw stalks, avoiding excessive compression or inadequate combing of local straw stalks, and ensuring that the straw stalks at the connection are evenly distributed and the force is balanced.

[0017] Optionally, the housing is connected to a drive cylinder that drives the housing to move radially.

[0018] Through the above technical solution, the drive cylinder can drive the housing to move radially, adapting to brush-shaped straw ropes of different diameters, ensuring the housing's limiting effect on straw ropes of different specifications, while avoiding interference with the movement of the straw ropes.

[0019] Optionally, the main rod has a sliding cavity inside, and a sliding cylinder is installed inside the sliding cavity. The piston rod of the sliding cylinder is connected to a slider, and a connecting rod is hinged to the circumferential surface of the slider. The circumferential surface of the main rod has a through hole, and the end of the connecting rod away from the slider passes through the through hole and is hinged to the connecting rod.

[0020] Through the above technical solution, the extension or retraction of the piston rod of the sliding cylinder can drive the slider to slide in the sliding cavity, and then drive the connecting rod to rotate around the hinge axis through the connecting rod, so that the connecting rod can more smoothly put the tension sleeve on the brush-shaped straw rope.

[0021] Optionally, the connecting rod is connected with an elastic cloth, and every two adjacent connecting rods are connected by the elastic cloth.

[0022] Through the above technical solution, the elastic cloth can seal the gap between the connecting rods, prevent the elastic sleeve from falling off from the gap, and ensure that the elastic sleeve is stably fitted on the connecting rod. At the same time, the elastic cloth has elasticity and does not affect the opening and closing action of the connecting rod. When the connecting rod contracts near the end of the brush-shaped grass rope, the grass stalks piled together by the push plate are arranged linearly. When the elastic cloth contracts, it can squeeze multiple grass stalks into an approximately circular distribution, which makes it easy for the elastic sleeve to tighten the end of the brush-shaped grass rope.

[0023] Optionally, the end of the connecting rod near the storage rod is curved outwards, and the end of the connecting rod near the storage rod is pointed.

[0024] Through the above technical solution, the outward-curving connecting rod can prevent the tension sleeve from slipping off the connecting rod. At the same time, the end of the connecting rod near the storage rod is pointed, which makes it easier to insert between the two tension sleeves and makes it easier to remove the tension sleeve from the storage rod.

[0025] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0026] 1. By setting up a conveyor belt and a connecting structure, two sections of brush-shaped straw rope are automatically connected together without manual intervention, solving the problem of easy injury from manual binding and greatly improving work efficiency;

[0027] 2. By setting a storage rod to provide loose and tight sleeve material to the connecting structure, manual intervention is further reduced, making the connecting device more convenient to use;

[0028] 3. By making the end of the connecting rod near the storage rod pointed, it can be inserted more smoothly between the two tension sleeves, making it easier for the connecting rod to remove the tension sleeve from the storage rod. Attached Figure Description

[0039] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0041] Reference Figure 1 A connecting device for brush-shaped grass ropes used for sand fixation and control includes a conveyor belt 1 and a connecting structure. The connecting structure is located between two conveyor belts 1. The connecting structure includes a connecting frame 2 and an elastic sleeve 3 for connecting two brush-shaped grass ropes together. The connecting frame 2 is connected to a connecting sleeve structure 4 for fitting the elastic sleeve 3 onto the two brush-shaped grass ropes. Two sets of connecting sleeve structures 4 are provided, and the two sets of connecting sleeve structures 4 are located on opposite sides of the two brush-shaped grass ropes. Conveyor belt 1 moves the brush-shaped straw ropes to the connecting structure 4. The connecting structure 4 fits the elastic sleeve 3 onto the ends of the two brush-shaped straw ropes, thus connecting them. The two sets of connecting structures 4 work simultaneously from both sides of the straw ropes, making the connection of the straw ropes tighter, the force more even, and less prone to damage. Moreover, the automated operation avoids operators being scratched or punctured by the straw stalks, solving the safety hazards of manual binding. The elastic sleeve 3 is made of elastic rubber material that is resistant to high and low temperatures and anti-aging, adapting to the extreme temperature difference environment of desert areas. Its elastic properties can closely fit the straw stalk distribution of the brush-shaped straw ropes, always maintaining a tight state under the impact of wind and sand, ensuring connection stability, and further enhancing the sand-fixing effect.

[0042] Reference Figure 2 and Figure 3 The connecting frame 2 is connected to a storage rod 5, and multiple storage rods 5 are arranged in a circumferential array. Multiple tension sleeves 3 are fitted onto the outside of the storage rods 5 to replenish the tension sleeves 3 for the connecting structure 4. The connecting frame 2 is connected to a feeding cylinder 51, and the piston rod of the feeding cylinder 51 is connected to a push ring 52, which is slidably connected to the storage rods 5. The storage rods 5 store multiple tension sleeves 3, eliminating the need for frequent manual addition of tension sleeves 3. Furthermore, the feeding cylinder 51 pushes the push ring 52, which pushes the tension sleeves 3 closer to the connecting structure 4, making it easier for the connecting structure 4 to smoothly fit the tension sleeves 3 onto the end of the brush-shaped straw rope, ensuring the continuity of the connection process.

[0043] Reference Figure 4 and Figure 5The connecting structure 4 includes a main rod 41, with multiple connecting rods 42 hinged to the circumferential surface of the main rod 41. The multiple connecting rods 42 are arranged in a circumferential array on the circumferential surface of the main rod 41, and the multiple connecting rods 42 are used to put the tension sleeve 3 on the storage rod 5 onto the end of the grass stalk. One end of the main rod 41 is connected to a push cylinder 7, and the main rod 41 is connected to the piston rod of the push cylinder 7. The main rod 41 and the piston rod of the push cylinder 7 are detachable, which makes it convenient for the operator to replenish the tension sleeve 3. The connecting rod 42 can rotate around the hinge axis with the main rod 41, allowing multiple connecting rods 42 to converge near the end of the storage rod 5. This pushes the cylinder 7 to move the main rod 41 and connecting rods 42 toward the storage rod 5, causing the connecting rods 42 to insert into the tension sleeve 3 on the storage rod 5. Subsequently, the multiple connecting rods 42 near the end of the storage rod 5 spread the tension sleeve 3 open, removing it from the storage rod 5. Then, the cylinder 7 pushes the main rod 41 and connecting rods 42 toward the brush-shaped straw rope. Subsequently, the multiple connecting rods 42 near the end of the brush-shaped straw rope converge, causing the multiple connecting rods 42 near the end of the storage rod 5 to open. At this time, the tension sleeve 3 on the connecting rod 42 opens and moves toward the brush-shaped straw rope, finally fitting onto it. To make the sliding of the tension sleeve 3 on the connecting rod 42 smoother, lubricating oil can be applied to the connecting rod 42 to reduce friction.

[0044] Reference Figure 4 and Figure 5 The main rod 41 has a sliding cavity 411 inside, and a sliding cylinder 412 is installed inside the sliding cavity 411. The piston rod of the sliding cylinder 412 is connected to a slider 413. A connecting rod 414 is hinged to the circumferential surface of the slider 413. A through hole 415 is opened on the circumferential surface of the main rod 41. The end of the connecting rod 414 away from the slider 413 passes through the through hole 415 and is hinged to the connecting sleeve rod 42. The extension or retraction of the piston rod of the sliding cylinder 412 can drive the slider 413 to slide in the sliding cavity 411, and then drive the connecting sleeve rod 42 to rotate around the hinge axis through the connecting rod 414, so that the connecting sleeve rod 42 can more smoothly put the tensioning sleeve 3 onto the brush-shaped straw rope.

[0045] Reference Figure 4 and Figure 5The connecting rod 42 is connected to an elastic cloth 421, and every two adjacent connecting rods 42 are connected by the elastic cloth 421. The elastic cloth 421 can seal the gap between the connecting rods 42, preventing the tension sleeve 3 from falling off from the gap, ensuring that the tension sleeve 3 is stably fitted on the connecting rod 42. At the same time, the elastic cloth 421 is elastic, so it does not affect the opening and closing action of the connecting rod 42. When the connecting rod 42 retracts near the end of the brush-shaped straw rope, the straw stalks piled together by the push plate 61 are arranged linearly. When the elastic cloth 421 retracts, it can squeeze multiple straw stalks into an approximately circular distribution, which makes it easy for the tension sleeve 3 to tighten the end of the brush-shaped straw rope. The end of the connecting rod 42 near the storage rod 5 is raised outward (raised angle 45-60 degrees), and the end of the connecting rod 42 near the storage rod 5 is pointed. The outward-curving connecting rod 42 can prevent the tension sleeve 3 from slipping off the connecting rod 42. At the same time, the end of the connecting rod 42 near the storage rod 5 is pointed, which makes it easier to insert between the two tension sleeves 3 and makes it easier to remove the tension sleeve 3 from the storage rod 5.

[0046] Reference Figures 6-8 The connecting frame 2 connects two semi-circular housings 6 arranged vertically. Each housing 6 has an arc-shaped sliding groove inside. A drive cylinder 65 is connected to each housing 6, which moves the housing 6 radially. The drive cylinder 65 can move the housing 6 radially to accommodate brush-shaped straw ropes of different diameters, ensuring the housing 6 effectively limits the movement of different specifications of straw ropes while avoiding interference with the rope's movement. A push plate 61 is installed inside the housing 6, slidingly connected to the housing 6 via the sliding groove. The housing 6 is located between two sets of conveyor belts 1. A drive motor 62 is connected to the housing 6. The output shaft of the drive motor 62 is connected to a drive gear 63, which meshes with a drive rack 64. The drive rack 64 is arc-shaped and has a sliding hole on one side of the housing 6. One side of the push plate 61 passes through the sliding hole and connects to the drive rack 64. After the upper and lower semi-circular shells 6 are closed, they can limit the connection ends of the two straw ropes to prevent the straw ropes from shifting during connection. The drive motor 62 provides a stable driving force, which drives the push plate 61 to slide smoothly along the slide groove through the gear and rack transmission. The transmission accuracy is high, and the moving distance and force of the push plate 61 can be precisely controlled. The arc-shaped drive rack 64 is adapted to the arc-shaped structure of the shell 6 to ensure that the sliding trajectory of the push plate 61 is consistent with the circumferential shape of the straw rope end. The grass stalks are gathered more evenly, avoiding excessive compression or inadequate combing of local straw stalks, and ensuring that the straw stalks at the connection are evenly distributed and the force is balanced.

[0047] Reference Figure 1The conveyor belt 1 consists of two sets, located on opposite sides of the connecting structure. Each set includes two conveyor belts, positioned on the left and right sides of the brush-shaped straw rope. Both conveyor belts are inclined at an angle of 30°-60°, and multiple baffles 11 are evenly fixed to their outer surfaces. The two sets of conveyor belts 1 respectively transport the straw rope to be connected and output the connected straw rope, forming a continuous production line. The inclined conveyor belts utilize gravity to keep the brush-shaped straw rope close to the belt surface, preventing it from slipping due to equipment vibration or slight tilting in the desert environment. The conveyor belts on both sides clamp the straw rope from the left and right sides, ensuring that the straw rope is accurately transported in a straight line to the center of the connecting structure, preventing transport deviation. The baffles 11 can segment and limit the brush-shaped straw rope, preventing it from slipping or stacking during transport, ensuring that the ends of each straw rope segment are accurately aligned, providing precise positioning for subsequent connections.

[0048] Furthermore, this application can reduce the laying time of the brush-like grass ropes by adding wheels and a power structure under the overall device, enabling the connection of the grass ropes simultaneously during the laying process in the desert.

[0049] The specific implementation of this embodiment is as follows: When it is necessary to connect the brush-shaped grass ropes together, the brush-shaped grass ropes are placed on the conveyor belt 1, and the conveyor belt 1 moves the brush-shaped grass ropes forward. Then, the second brush-shaped grass rope is placed on the conveyor belt 1 until the tail of the first grass rope and the end of the second grass rope move between the two housings 6. Then, the drive cylinder 65 drives the two housings 6 to move closer to each other, covering the tail of the first grass rope and the end of the second grass rope between the housings 6. Then, the drive motor 62 rotates, driving the drive gear 63 to rotate, which in turn drives the drive rack 64 to move, which in turn drives the push plate 61 to slide along the slide groove, so that the push plate 61 pushes the grass stalks at the end of the brush-shaped grass rope together, pushing the piston rod of the cylinder 7 to extend, so that the main rod 41 and the connecting rod 42 move closer to the brush-shaped grass rope. The connecting rod 42 and the elastic cloth cover the grass stalks at the end of the brush-shaped grass rope. Then, the sliding cylinder 412 drives the slider 413 in the sliding cavity. The slider 413 slides within the 411, and the connecting rod 414 drives the connecting rod 42 to rotate around the hinge axis, causing the multiple connecting rods 42 to contract near the brush-like straw rope and expand away from the brush-like straw rope. This causes the tension sleeve 3 on the connecting rod 42 to slide towards the brush-like straw rope and finally fit onto it. Then, the sliding cylinder 412 drives the multiple connecting rods 42 to contract near the storage rod 5, and then pushes the cylinder 7 to move the main rod 41 and the connecting rods 42 towards the storage rod 5, so that the ends of the multiple connecting rods 42 pass through the middle of the multiple storage rods 5. Then, the multiple connecting rods 42 slightly open near the storage rod 5, so that the connecting rods 42 remove the tension sleeve 3 from the storage rod 5 for the next brush-like straw rope end connection. Compared with the existing manual connection, this application uses automated operation, eliminating the need for manual contact with the straw rope end, avoiding operator injury from straw stalks, and solving the safety hazards of manual binding.
