Description

Technical Field

[0001] This utility model relates to the field of desertification control engineering technology, and in particular to a sand barrier installation device. Background Technology

[0002] Sand barriers, as a key engineering measure to suppress wind erosion and desertification, directly affect the sand grain fixation effect through their structural integrity. Among them, vertical sand barriers have become the preferred solution for controlling mobile sand dunes due to the synergistic effect of wind speed attenuation rate (30%~50%) and sand transport rate reduction rate (60%~80%). However, the existing technology system has significant technical barriers:

[0003] Traditional manual planting relies on simple tools such as shovels, which has three major technical drawbacks when operating in desertification control areas (average treatment area > 100 hectares): 1) Low work efficiency (average planting volume < 100m² per day), with labor costs accounting for 65% to 70% of the total project cost; 2) Difficulty in controlling the planting angle, resulting in a 40% to 60% decrease in the wind erosion resistance of the sand barriers; 3) High labor intensity, posing serious occupational health risks.

[0004] Existing mechanized equipment, such as the scheme shown in Chinese patent CN201920197148.7, although achieving preliminary automation, has structural defects in its core technology: the insertion mechanism adopts a unidirectional linear execution mode (single dimension in the longitudinal or transverse direction). After the transverse sand barrier is inserted, the transverse sand barrier forms a physical interference zone (interference rate of 38%~45%) during longitudinal operation, resulting in a secondary insertion success rate of less than 60%.

[0005] Therefore, there is an urgent need to develop a sand barrier installation equipment with adaptive sand layer embedding and three-dimensional forming capabilities to break through existing technological bottlenecks and improve the mechanization level of desertification control projects. Utility Model Content

[0006] In view of this, the present invention provides a sand barrier installation device, the main purpose of which is to improve the installation efficiency and at the same time reduce the problem of unstable sand barrier quality caused by manual installation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a sand barrier installation device, comprising:

[0009] The support assembly includes a fixed frame and a movable frame that slides with the fixed frame.

[0010] The mobile mechanism, located at the bottom of the fixed frame, is used to drive the equipment to move across the sand.

[0011] The material roll support assembly is symmetrically located on the left and right sides of the front end of the fixed frame and is used to support the sand barrier material roll;

[0012] The lifting assembly includes a lifting drive device arranged longitudinally between a fixed frame and a movable frame. The fixed part of the lifting drive device is fixedly connected to the fixed frame, and the output end is movably connected to the movable frame. The axial displacement of the output end drives the movable frame to move vertically up and down relative to the fixed frame.

[0013] The sand-inserting assembly is distributed along the bottom periphery of the movable frame and consists of a first sand-inserting assembly, a second sand-inserting assembly, and a third sand-inserting assembly connected end to end to form a U-shaped structure. The first and third sand-inserting assemblies are spatially parallel and opposite each other, while the second sand-inserting assembly is vertically positioned between the first and third sand-inserting assemblies. The first sand-inserting assembly includes a fixed plate fixed to the bottom end of the movable frame, a movable plate parallel to the fixed plate and movably connected to the bottom end of the movable frame, and a drive mechanism for driving the movable plate toward or away from the fixed plate. The structures of the second and third sand-inserting assemblies are identical to those of the first sand-inserting assembly.

[0014] Conveying components, which are capable of conveying and forming sand barrier belts with orthogonal bending structures; and

[0015] The cutting assembly, symmetrically arranged on both sides of the front of the fixed frame and located between the synchronous belt conveyor and the material roll support assembly, is used to cut the continuous sand barrier belt into individual sand barrier pieces.

[0016] According to the aforementioned sand barrier installation equipment, the material roll support assembly includes:

[0017] A cylindrical mounting base, with sand barrier material rolls placed in the cylindrical mounting base on both sides of the front part of its fixed frame; the cylindrical mounting base includes a base and side cylinders, with the side cylinders having vertically opened discharge ports; the base rotates relative to the circumference of the cylinders; and

[0018] The roll positioning rod, which is located in the cylindrical mounting seat, is used to detachably fix the sand barrier roll.

[0019] According to the aforementioned sand barrier installation device, the lifting assembly also includes a first slide rail and a first slider, with the first slide rail being vertically arranged;

[0020] The first slide rail is disposed on one of the fixed frame and the sand insertion assembly, and the first slider is disposed on the other of the fixed frame and the sand insertion assembly. The first slider and the first slide rail form a sliding fit relationship.

[0021] According to the aforementioned sand barrier installation device, the drive mechanism includes a first motor fixedly installed at the bottom of the movable frame and located on the outer side of the movable plate, and a first gear is fixedly assembled at the end of the output shaft of the first motor.

[0022] The bottom of the movable frame is fixedly connected with at least two connecting plates at intervals;

[0023] A connecting rod is vertically fixed to the top of the movable plate, and a second gear is coaxially fixed on the connecting rod. The second gear and the first gear form a meshing transmission pair.

[0024] The connecting rod is rotatably inserted into the shaft hole of each connecting plate, and the axis of the connecting rod is rotatedly fitted with the connecting plate;

[0025] When the first motor drives the motor, the meshing transmission between the first gear and the second gear drives the connecting rod to rotate around its own axis, thereby causing the movable plate to move toward or away from the fixed plate.

[0026] According to the aforementioned sand barrier installation equipment, the conveying components include:

[0027] A synchronous belt conveyor mechanism is mounted on a fixed frame and located above the sand insertion assembly; the synchronous belt conveyor mechanism is configured to operate in either forward or reverse direction to selectively drive the sand barrier roll on one of the roll support assemblies to perform an unwinding operation.

[0028] The side-push compaction mechanism is located on the outside of the movable frame. Three sets of the side-push compaction mechanism are arranged, each aligned vertically with the sand-inserting assembly. A synchronous belt conveyor works in conjunction with the side-push compaction mechanism to clamp and move the sand barrier belt forward synchronously.

[0029] An arc-shaped guide plate, positioned between adjacent side-push compaction mechanisms, guides the sand barrier belt to form a bend orthogonal to the conveying direction.

[0030] Furthermore, the side-push compaction mechanism includes:

[0031] The first mounting part is fixedly installed on the outer side wall of the movable frame;

[0032] The first linear drive device is fixedly installed on the side of the first mounting part facing away from the movable frame. Its output end is connected to a push plate, and multiple parallel rotating rollers are arranged at intervals along the horizontal direction on the working surface of the push plate.

[0033] The guide assembly includes four guide rods that are vertically fixed to the back side of the push plate. Each guide rod is arranged in a rectangular array along the four corners of the push plate. A guide through hole is provided on the first mounting part at the position corresponding to each guide rod. A linear bearing is fixedly installed in each guide through hole as a bushing. The guide rod can slide through the corresponding bushing.

[0034] The first linear drive device drives the push plate to move linearly along the axial direction of the guide rod, causing the rotating roller and the synchronous belt conveyor to move in opposite directions to form a clamping and conveying of the sand barrier belt; the contact surfaces of the rotating roller and the synchronous belt conveyor form a rolling friction pair, realizing synchronous forward movement in the clamping state.

[0035] According to the aforementioned sand barrier installation equipment, the cutting components include:

[0036] The second mounting part is fixedly installed on the front side of the fixed frame; the middle of the second mounting part is through which the continuous sand barrier belt passes;

[0037] The second linear drive device is fixed on the second mounting part;

[0038] The first cutting tool has its side fixed to the output end of the second linear drive device;

[0039] There are two second slide rails, which are respectively located on the second mounting parts at the corresponding positions at both ends of the first cutter;

[0040] The second slider is located at both ends of the first cutter, and the first slider and the first slide rail form a sliding fit relationship;

[0041] The third slide rail is located at the upper and lower ends of the second mounting part and is arranged parallel to the second slide rail;

[0042] The third slider has a sliding fit with the third slide rail;

[0043] The second cutter is fixedly connected to the third slider at both ends;

[0044] The first rack is fixed on the second slider and is arranged parallel to the second slide rail;

[0045] The second rack is fixed on the third slider and is arranged parallel to the third slide rail;

[0046] The third gear is rotatably mounted on the second mounting part, and the third gear meshes with the first rack and the second rack;

[0047] The second linear drive device drives the first cutter to move along the second slide rail. Through the meshing transmission of the first rack, the third gear and the second rack, the second cutter is driven to move synchronously in the opposite direction along the third slide rail, so that the first cutter and the second cutter move towards each other, thereby cutting the continuous sand barrier belt into independent sand barrier pieces.

[0048] According to the aforementioned sand barrier installation equipment, the sand barrier installation equipment also includes a sand-pushing component to achieve sand leveling; the sand-pushing component is located at the front end of the fixed frame; the sand-pushing component includes:

[0049] The third mounting part is fixed to the front end of the fixed frame;

[0050] The third linear drive device is fixed to one side of the third mounting part, with its output end facing downwards;

[0051] The fourth mounting part is fixedly connected to the output end of the third linear drive device, and the fourth mounting part is arranged parallel to the third mounting part;

[0052] The sand-pushing plate is fixed at the bottom of the fourth mounting part;

[0053] The sand-pushing assembly also includes a fourth slide rail and a fourth slider, with the fourth slide rail being vertically positioned;

[0054] The fourth slide rail is disposed on one of the third mounting part and the fourth mounting part, and the fourth slider is disposed on the other of the third mounting part and the fourth mounting part. The fourth slide rail and the fourth slider form a sliding fit relationship.

[0055] Compared with the prior art, the present invention has the following beneficial effects:

[0056] (1) The sand barrier installation equipment forms a continuous operation system of "dynamic clamping-forming-insertion", realizing the full-process mechanized operation from material transportation and forming to precise insertion, replacing the existing manual sand barrier installation method, improving production efficiency and saving labor. At the same time, it also reduces the problem of unstable sand barrier quality that exists in manual installation.

[0057] (2) The sand barrier insertion equipment clamps and conveys the sand barrier belt synchronously and bends it into shape to form an orthogonally bent sand barrier belt. After cutting, it forms an orthogonally bent sand barrier piece, realizing efficient and precise processing of sand barrier materials.

[0058] (3) The sand barrier installation equipment has good terrain adaptability and is particularly suitable for mobile sand dune control projects. When it is necessary to level the sand, the output end of the third linear drive device drives the fourth installation part to move down, which in turn drives the sand pushing plate to move down. The sand pushing plate comes into contact with the sand layer. During the operation of the moving mechanism, the sand pushing plate levels the sand layer, making it convenient for the sand insertion component to insert the orthogonally bent sand barrier piece into the sand layer. The displacement of the output end of the third linear drive device can be adjusted to control the height of the sand pushing plate, thereby adjusting the thickness of the sand layer being leveled.

[0096] To make the technical problem to be solved, the technical solution and advantages of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figures 1 to 27 The technical solution of this utility model is clearly and completely described in conjunction with specific embodiments.

[0097] This utility model provides a sand barrier insertion device for inserting orthogonally bent sand barrier panels into sand. The structure of the sand barrier insertion device is as follows: Figures 1 to 19 As shown.

[0098] The sand barrier installation equipment includes: support assembly 1, moving mechanism 2, material roll support assembly 3, lifting assembly 4, sand insertion assembly 5, conveying assembly 6, and cutting assembly 7.

[0099] Specifically:

[0100] The support component 1 includes a fixed frame 11 and a movable frame 12 that slides with the fixed frame 11. The movable frame 12 can move up and down relative to the fixed frame 11.

[0101] The mobile mechanism 2 is located at the bottom of the fixed frame 11 and is used to drive the equipment to move on sand. The mobile mechanism 2 is a tracked walking mechanism, which has good stability and strong climbing ability. The tracked walking mechanism may include track chains, their drive unit, and guide tensioning devices. The track chains need to adopt a hollow or embossed design (such as herringbone patterns) to enhance their engagement with the sand. Lightweight aluminum alloy or high-strength composite materials (such as carbon fiber reinforced nylon) are preferred for the chain links. The guide tensioning device needs to have a dynamic adjustment function to compensate for the elastic deformation of the tracks when moving on sand. Alternatively, the mobile mechanism 2 can also be a wheeled walking mechanism, capable of moving forward with low power. The tires are wide-section, low-pressure tires to increase the contact area with the ground; the tread pattern needs to be a deep spiral or block pattern to improve traction.

[0102] The material roll support assembly 3 is symmetrically arranged on the left and right sides of the front end of the fixed frame 11 to support the sand barrier material roll. The material roll support assembly 3 includes: a cylindrical mounting base 31 on both sides of the front part of the fixed frame, in which the sand barrier material roll is placed; and a roll positioning rod 32, which is arranged in the cylindrical mounting base 31 for detachably fixing the sand barrier material roll. The cylindrical mounting base 31 includes a base 311 and a side cylinder 312. The side cylinder 312 has a vertically opened discharge port 313, from which the continuous sand barrier belt moves to the conveying assembly for feeding. The base 311 rotates relative to the cylinder circumference. Specifically, the side cylinder 312 is relatively fixed, while the base 311 can rotate, which reduces the resistance during discharge and facilitates discharge.

[0103] The lifting assembly 4 includes a lifting drive device 41 arranged longitudinally between the fixed frame 11 and the movable frame 12. The fixed part of the lifting drive device 41 is fixedly connected to the fixed frame 11, and the output end is movably connected to the movable frame 12. The axial displacement of the output end drives the movable frame 12 to move vertically up and down relative to the fixed frame 11.

[0104] The lifting assembly 4 also includes a first slide rail 42 and a first slider 43. The first slide rail 42 is vertically arranged. The first slide rail 42 is disposed on one of the fixed frame 11 and the sand insertion assembly 5, and the first slider 43 is disposed on the other of the fixed frame 11 and the sand insertion assembly 5. The first slider 43 and the first slide rail 42 form a sliding engagement relationship. In this embodiment, the first slide rail 42 is disposed on the fixed frame 11, and the first slider 43 is disposed on the sand insertion assembly 5. Further, the first slider 43 is disposed on the fixed plate 51 of the sand insertion assembly 5. By providing multiple first slide rails 42 and first sliders 43, the stability of the movable frame 12 moving up and down relative to the fixed frame 11 is improved.

[0105] The sand-inserting assembly 5 is distributed along the bottom periphery of the movable frame and consists of a first sand-inserting assembly 5a, a second sand-inserting assembly 5b, and a third sand-inserting assembly 5c connected end-to-end to form a U-shaped structure. The first sand-inserting assembly 5a and the third sand-inserting assembly 5c are spatially parallel and opposite each other, while the second sand-inserting assembly 5b is vertically positioned between the first sand-inserting assembly 5a and the third sand-inserting assembly 5c. The first sand-inserting assembly 5a includes a fixed plate 51 fixed to the bottom end of the movable frame, a movable plate 52 parallel to the fixed plate 51 and movably connected to the bottom end of the movable frame, and a driving mechanism 53 that drives the movable plate 52 toward or away from the fixed plate 51. The structures of the second sand-inserting assembly 5b and the third sand-inserting assembly 5c are identical to those of the first sand-inserting assembly 5a. The sand-inserting assembly 5 enables the vertical insertion of sand barriers.

[0106] The fixed plate 51 is provided with an array of fixed plate through holes 511, and the movable plate 52 is provided with an array of movable plate through holes 521, such as... Figure 10 and Figure 11 As shown. The through hole 511 in the fixed plate and the through hole 521 in the movable plate are designed so that after sand enters the sand barrier, some sand flows from the through hole 511 in the fixed plate and the through hole 521 in the movable plate into the space between the fixed plate 51 and the movable plate 52, so that the sand barrier will not be carried out when the fixed plate 51 and the movable plate 52 exit the sand.

[0107] The lifting drive device 41 drives the movable frame 12 to move downwards, which in turn drives the sand insertion component 5 to move downwards. The sand insertion component 5 is inserted into the sand layer, which in turn drives the sand barrier plate to be inserted into the sand layer. After the sand barrier plate is inserted, the lifting drive device 41 drives the movable frame 12 to move upwards, which in turn drives the sand insertion component 5 to move upwards, and the sand insertion component 5 is pulled out of the sand layer.

[0108] In the optional embodiments of this example, a preferred structure for the drive mechanism 53 is as follows: The drive mechanism 53 includes a first motor 531 fixedly mounted on the bottom end of the movable frame 12 and positioned on the outer side of the movable plate 52. A first gear 532 is fixedly mounted on the output shaft end of the first motor 531. At least two connecting plates 533 are fixedly connected at intervals to the bottom end of the movable frame 12. A connecting rod 534 is vertically fixedly connected to the top end of the movable plate 52. A second gear 535 is coaxially fixedly mounted on the connecting rod 534, and the second gear 535 and the first gear 532 form a meshing transmission pair. The connecting rod 534 rotatably passes through the shaft holes of each connecting plate 533, and the axis of the connecting rod 534 and the connecting plate 533 form a rotational fit. Bearings are provided in the shaft holes of the connecting plates 533, and the connecting rod 534 passes through the bearings. The operation of the drive mechanism 53 is as follows: when the first motor 531 drives, the first gear 532 and the second gear 535 mesh and drive the connecting rod 534 to rotate around its own axis, thereby driving the movable plate 52 to move towards or away from the fixed plate 51.

[0109] Another possible structure for the drive mechanism 53: The drive mechanism 53 is a cylinder, with the cylinder body fixed to the bottom end of the movable frame 12, and the piston end hinged to the movable plate 52. The extension and retraction of the cylinder causes the movable plate 52 to move towards or away from the fixed plate 51. Other equivalent alternatives that can be conceived by those skilled in the art can also serve as the drive mechanism 53 in this embodiment of the present invention.

[0110] The conveying assembly 6 is a sand barrier belt capable of conveying and forming an orthogonal bending structure. The conveying assembly 6 includes a synchronous belt conveying mechanism 61 mounted on the fixed frame 11 and located above the sand insertion assembly 5, and three sets of side-push compaction mechanisms 62 located outside the movable frame 12. The three sets of side-push compaction mechanisms 62 are vertically aligned with the sand insertion assembly 5. The synchronous belt conveying mechanism 61 and the side-push compaction mechanisms 62 cooperate to clamp the sand barrier belt and move it forward synchronously. Adjacent side-push compaction mechanisms 62 are provided with arc-shaped guide plates 63 to guide the sand barrier belt to form a bend orthogonal to the conveying direction. The synchronous belt conveying mechanism 61 is configured to operate in either forward or reverse direction to selectively drive the sand barrier roll on one of the roll support assemblies 3 to perform an unwinding operation.

[0111] In the optional embodiment, a preferred synchronous belt conveyor mechanism 61 includes: a frame 611, a second motor 612, multiple guide rollers 613, and a synchronous belt 614. The frame 611 is fixed to a fixed frame 11. The second motor 612 and the multiple guide rollers 613 are mounted on the frame 611, and the output shaft of the second motor 612 is coaxially connected to one of the guide rollers 613. The synchronous belt 614 is wrapped around the guide rollers 613. When the second motor 612 is energized, the guide rollers 613 drive the synchronous belt 614 to move in a uniform linear motion along its length. The synchronous belt conveyor mechanism 61 also includes a tension adjustment mechanism (not shown in the figure).

[0112] In the optional embodiment, the preferred side-push compaction mechanism 62 includes: a first mounting part 621, which is fixedly mounted on the outer side wall of the movable frame 12; a first linear drive device 622, which is fixedly disposed on the side of the first mounting part 621 facing away from the movable frame 12, and its output end is connected to a push plate 623, with a plurality of parallel rotating rollers 624 arranged at intervals along the horizontal direction on the working surface of the push plate 623; and a guide assembly, including four guide rods 625 vertically fixed on the back side of the push plate 623, with each guide rod 625 arranged in a rectangular array along the four corners of the push plate 623. A guide through hole is provided on the first mounting part 621 at the position corresponding to each guide rod 625, and a linear bearing is fixedly installed in each guide through hole as a bushing 626, with the guide rod 625 slidably passing through the corresponding bushing 626. The first linear drive device 622 drives the push plate 623 to move linearly along the axial direction of the guide rod 625, causing the roller 624 and the synchronous belt conveyor mechanism 61 to move in opposite directions to clamp and convey the sand barrier belt. The contact surfaces of the roller 624 and the synchronous belt conveyor mechanism 61 form a rolling friction pair, achieving synchronous forward movement under clamping conditions. Furthermore, the surface of the roller 624 is covered with a high-friction coefficient elastic layer, and its axial direction is orthogonal to the conveying direction of the synchronous belt conveyor mechanism 61. A baffle can also be provided on the outer side of the roller 624 away from the push plate 623 to prevent the sand barrier belt from entering the roller 624.

[0113] The conveying assembly 6 uses the opposing movement of the synchronous belt conveying mechanism 61 and the rotating roller 624 to form a flexible clamp, thereby achieving stable conveying of the sand barrier belt.

[0114] The cutting components 7 are symmetrically arranged on both sides of the front of the fixed frame 11 and located between the synchronous belt conveyor 61 and the material roll support assembly 3. They are used to cut the continuous sand barrier belt into independent sand barrier pieces. The arc-shaped guide plate 63 is used to guide the straight sand barrier belt to bend and move it into the space between the adjacent side-pushing compaction mechanism 62 and the synchronous belt conveyor 61 to form sand barrier pieces with an orthogonal bending structure.

[0115] In the optional embodiment, a preferred cutting component 7 includes: a second mounting part 71, which is fixedly mounted on the front side of the fixed frame 11; the second mounting part 71 has a through-hole in the middle, allowing the continuous sand barrier belt to pass through the second mounting part 71; a second linear drive device 72, which is fixedly mounted on the second mounting part 71; a first cutter 73, whose side is fixedly mounted on the output end of the second linear drive device 72; two second slide rails 74, which are respectively provided on the second mounting part 71 at corresponding positions at both ends of the first cutter 73; and two second sliders 75, which are provided at both ends of the first cutter 73, and the first sliders 73 and the first slide rails 74 are connected. 2. A sliding fit relationship is formed; a third slide rail 76 is provided at the upper and lower ends of the second mounting part 71 and is arranged parallel to the second slide rail 74; a third slider 77 is in a sliding fit relationship with the third slide rail 76; a second cutter 78 is fixedly connected to the third slider 77 at both ends; a first rack 79 is fixed on the second slider 75 and is arranged parallel to the second slide rail 74; a second rack 7a is fixed on the third slider 77 and is arranged parallel to the third slide rail 76; a third gear 7b is rotatably mounted on the second mounting part 71, and the third gear 7b meshes with the first rack 79 and the second rack 7a. The operation of the cutting assembly 7 is as follows: the second linear drive device 72 drives the first cutter 73 to move along the second slide rail 74. Through the meshing transmission of the first rack 79, the third gear 7b and the second rack 7a, the second cutter 78 is driven to move synchronously in the opposite direction along the third slide rail 76, so that the first cutter 73 and the second cutter 78 move towards each other, thereby cutting the continuous sand barrier belt into independent sand barrier pieces.

[0116] The cutting component 7 can also employ the grass-cutting mechanism described in CN 114808983 B to cut the continuous sand barrier strip into individual sand barrier pieces. Other equivalent alternatives that can be conceived by those skilled in the art can also serve as the cutting component 7 in this embodiment of the present invention.

[0117] One side (left or right) of the material roll support assembly 3 supplies sand barrier belt to the conveying assembly 6. When the sand barrier belt forms an orthogonally bent structure between the synchronous belt conveying mechanism 61 and the side-push compaction mechanism 62, the conveying assembly 6 stops running, and the cutting assembly 7 cuts the sand barrier belt to form orthogonally bent sand barrier sheets. Specifically, when the right side of the material roll support assembly 3 supplies sand barrier belt to the conveying assembly 6, the first sand insertion assembly 5a, the second sand insertion assembly 5b, and the conveying assembly 6 corresponding to the first sand insertion assembly 5a and the second sand insertion assembly 5b respectively operate to form orthogonally bent sand barrier sheets, which can form L-shaped sand barrier sheets; when the left side of the material roll support assembly 3 supplies sand barrier belt to the conveying assembly 6, the third sand insertion assembly 5c, the second sand insertion assembly 5b, and the conveying assembly 6 corresponding to the third sand insertion assembly 5c and the second sand insertion assembly 5b respectively operate to form orthogonally bent sand barrier sheets, which can form mirror-shaped sand barrier sheets.

[0118] The sand barrier installation device also includes a sand-pushing component 8 to level the sand; the sand-pushing component 8 is located at the front end of the fixed frame 11. The sand-pushing component 8 includes: a third mounting part 81, which is fixed at the front end of the fixed frame 11; a third linear drive device 82, which is fixed on one side of the third mounting part 81 with its output end facing downward; a fourth mounting part 83, which is fixedly connected to the output end of the third linear drive device 82, and the fourth mounting part 83 is arranged parallel to the third mounting part 81; a sand-pushing plate 84, which is fixed at the bottom end of the fourth mounting part 83; the sand-pushing component 8 also includes a fourth slide rail 85 and a fourth slider 86, the fourth slide rail 85 being arranged vertically; the fourth slide rail 85 is disposed on one of the third mounting part 81 and the fourth mounting part 83, and the fourth slider 86 is disposed on the other of the third mounting part 81 and the fourth mounting part 83, the fourth slide rail 85 and the fourth slider 86 forming a sliding fit relationship. In this embodiment, the fourth slide rail 85 is disposed on the third mounting part 81, and the fourth slider 86 is disposed on the fourth mounting part 83. The operation of the sand-pushing assembly 8 is as follows: when it is necessary to level the sand, the output end of the third linear drive device 82 drives the fourth mounting part 83 to move down, thereby driving the sand-pushing plate 84 to move down. The sand-pushing plate 84 contacts the sand layer. During the operation of the moving mechanism 2, the sand-pushing plate 84 levels the sand layer, making it convenient for the sand-inserting assembly 5 to insert sand barrier plates into the sand layer. The displacement of the output end of the third linear drive device 82 can be adjusted to control the height of the sand-pushing plate 84, thereby adjusting the thickness of the sand layer being leveled.

[0119] The lifting drive device 41, the first linear drive device 622, the second linear drive device 72 and the third linear drive device 82 are specifically including but not limited to linear drive components such as cylinders, hydraulic cylinders, electric actuators, etc., as long as they can provide linear driving force.

[0120] The first mounting section 621, the second mounting section 71, the third mounting section 81 and the fourth mounting section 83 are composed of plate-like structures or frame structures, which can be used to install and fix other components.

[0121] The sand barrier installation equipment also includes a control component 9, which includes a control box 91 fixedly mounted on a fixed frame 11, and a control handle 92 mounted on the control box 91. The control box 91 is electrically connected to the moving mechanism 2, the lifting drive device 41, the drive mechanism 53 of the sand insertion component 5, the synchronous belt conveyor mechanism 61, the side-push compaction mechanism 62, the cutting component 7, and the sand-pushing component 8 to achieve mechanical operation control.

[0122] In the optional scheme of this embodiment, more preferably, the sand barrier insertion device provided in this embodiment also includes a displacement monitoring component, which is disposed on the moving mechanism 2 or the support component 1. The displacement monitoring component is communicatively connected to the control component 9. The control component 9 is used to receive the displacement information of the moving mechanism 2 monitored by the displacement monitoring component, so as to control the opening and closing of the moving mechanism 2 in a timely manner. Specifically, the displacement monitoring component can be set as a conventional displacement sensor and disposed on the moving mechanism 2.

[0123] The process of the sand barrier installation equipment provided in this embodiment is as follows: moving and positioning → sand barrier belt transfer → clamping and conveying → bending and shaping → fixed-length cutting → sand barrier release → sand insertion operation → reset cycle. The specific working process is as follows:

[0124] After the moving mechanism 2 moves the entire equipment to a specific position, the material roll support assembly 3 transfers the sand barrier belt to the conveying assembly 6. Specifically, the end of the sand barrier belt can be manually fed into the beginning of the conveying assembly 6. The first linear drive device 622 drives the push plate 623 to move linearly along the axial direction of the guide rod 625. The sand barrier belt is clamped between the side-push compaction mechanism 62 and the synchronous belt conveying mechanism 61. The side-push compaction mechanism 62 and the synchronous belt conveying mechanism 61 generate opposite displacements to form a clamping and conveying of the sand barrier belt, realizing synchronous forward movement in the clamped state. The arc-shaped guide plate 63 is used to guide the straight sand barrier belt to bend and move it into the space between the adjacent side-push compaction mechanism 62 and the synchronous belt conveying mechanism 61, forming a sand barrier belt with an orthogonal bending structure. When the sand barrier belt has been conveyed to the path length of the two adjacent side-push compaction mechanisms 62, the synchronous belt conveyor mechanism 61 stops operating. At this time, the cutting component 7 operates to cut the continuous sand barrier belt into independent sand barrier pieces. Then, the side-push compaction mechanism 62 moves away from the synchronous belt conveyor mechanism 61, losing its clamping effect on the sand barrier pieces. The bottom end of the sand barrier piece falls between the fixed plate 51 and the movable plate 52 of the sand insertion component 5. The lifting drive device 41 drives the movable frame 12 to move downward, which in turn drives the sand insertion component 5 to move downward. The sand insertion component 5 is inserted into the sand layer. The drive mechanism 53 drives the movable plate 52 to move away from the fixed plate 51, causing the sand barrier piece to be inserted into the sand layer. After the sand barrier piece is inserted, the lifting drive device 41 drives the movable frame 12 to move upward, which in turn drives the sand insertion component 5 to move upward. The sand insertion component 5 is pulled out of the sand layer. The drive mechanism 53 drives the movable plate 52 to move closer to and fit against the fixed plate 51. This completes one sand barrier insertion process. The moving mechanism 2 continues to move to perform the next sand barrier insertion.

[0125] In this embodiment of the invention, the orthogonal bending structure is formed by a longitudinal sand barrier extending from the end of the transverse sand barrier along a direction perpendicular to the length of the transverse sand barrier, forming an orthogonal bending structure with the transverse sand barrier. The longitudinal sand barrier being perpendicular to the length of the transverse sand barrier can have two possible configurations: extending in a first direction to form a first bending configuration; or extending in a second direction opposite to the first direction to form a second bending configuration. The first and second bending configurations are mirror-symmetrical structures. For example, if the first bending configuration is L-shaped, the second bending configuration is a mirror image of the L-shaped structure.

[0126] The sand barrier installation device of this utility model has the following beneficial effects:

[0127] (1) The sand barrier installation equipment forms a continuous operation system of "dynamic clamping-forming-insertion", realizing the full-process mechanized operation from material transportation and forming to precise insertion, replacing the existing manual sand barrier installation method, improving production efficiency and saving labor. At the same time, it also reduces the problem of unstable sand barrier quality that exists in manual installation.

[0128] (2) The sand barrier installation equipment clamps and conveys the sand barrier belt synchronously and bends it into shape to form a sand barrier belt with an orthogonal bending structure. After cutting, it forms a sand barrier piece with an orthogonal bending structure, thus realizing efficient and precise processing of sand barrier materials.

[0129] (3) The sand barrier installation equipment has good terrain adaptability and is particularly suitable for mobile sand dune control projects. When it is necessary to level the sand, the output end of the third linear drive device drives the fourth mounting part to move down, which in turn drives the sand pushing plate to move down. The sand pushing plate comes into contact with the sand layer. During the operation of the moving mechanism, the sand pushing plate levels the sand layer, making it convenient for the sand barrier components to insert the sand barrier pieces into the sand layer. The displacement of the output end of the third linear drive device can be adjusted to control the height of the sand pushing plate, thereby adjusting the thickness of the sand layer being leveled.

[0130] This utility model embodiment provides a method for installing sand barriers using sand barrier installation equipment, the first method being as follows: Figures 20 to 24 As shown, the arrow indicates the direction of travel of the sand barrier installation equipment. The sand barrier installation method includes the following steps:

[0131] Step S1: Insert the first row of horizontal sand barriers and the vertical sand barriers perpendicularly connected to them into the sand using sand barrier insertion equipment to form an orthogonal curved sand barrier.

[0132] Step S2: Repeat step S1 in the forward direction along the first row to form the first row of continuous sand barrier structure;

[0133] Step S3: Move the sand barrier installation device to the starting position of the second row, which is parallel and spaced apart from the first row, and repeat step S2 to complete the forward installation of the second row of continuous sand barrier structures.

[0134] Step S4: Repeat steps S2 to S3 until a grid array composed of multiple rows of parallel sand barrier structures is formed.

[0135] During the installation of the sand barrier, only the sand barrier rolls on one side of the roll support assembly are used. Specifically, in this embodiment, only the sand barrier rolls on the right side roll support assembly are used. The right side roll support assembly 3 supplies the sand barrier belt to the conveying assembly 6. The first sand insertion assembly 5a, the second sand insertion assembly 5b, and the conveying assembly 6, which are respectively located at the positions corresponding to the first sand insertion assembly 5a and the second sand insertion assembly 5b, run to form sand barrier sheets with orthogonal bending structures, which can form L-shaped sand barrier sheets.

[0136] In the first method, the sand barrier installation equipment travels forward from left to right, using only the sand barrier rolls on the right-side roll support assembly. If the sand barrier installation equipment travels forward from right to left, it uses only the sand barrier rolls on the left-side roll support assembly.

[0137] The sand barrier installation method is unidirectional continuous installation, forming an array through a cycle of "forward installation-translation-forward installation".

[0138] This utility model embodiment provides another method for installing sand barriers using sand barrier installation equipment, such as... Figures 25 to 27 As shown, the arrow indicates the direction of travel of the sand barrier installation equipment. The sand barrier installation method includes the following steps:

[0139] Step S1: Insert the first row of horizontal sand barriers and the vertical sand barriers perpendicularly connected to them into the sand using sand barrier insertion equipment to form an orthogonal curved sand barrier.

[0140] Step S2: Repeat step S1 in the forward direction along the first row to form the first row of continuous sand barrier structure;

[0141] Step S3': Turn the sand barrier installation equipment around and move it to the end of the second row, which is parallel to and spaced apart from the first row. Repeat step S2 in reverse to complete the installation of the second row of continuous sand barrier structures.

[0142] Step S4', and Step S2 and Step S3' are executed repeatedly to form a multi-row grid array by alternating forward and reverse insertion;

[0143] During the forward insertion of the sand barrier, the sand barrier rolls on one side of the roll support assembly are used; during the reverse insertion, the sand barrier rolls on the other side of the roll support assembly are used. Specifically, during the forward insertion, the roll support assembly 3 on the right supplies the sand barrier belt to the conveying assembly 6. The first sand insertion assembly 5a, the second sand insertion assembly 5b, and the conveying assembly 6 corresponding to the first sand insertion assembly 5a and the second sand insertion assembly 5b respectively operate to form sand barrier pieces with orthogonal bending structures, which can form L-shaped sand barrier pieces. During the reverse insertion, the roll support assembly 3 on the left supplies the sand barrier belt to the conveying assembly 6. The third sand insertion assembly 5c, the second sand insertion assembly 5b, and the conveying assembly 6 corresponding to the third sand insertion assembly 5c and the second sand insertion assembly 5b respectively operate to form sand barrier pieces with orthogonal bending structures, which can form mirror-shaped sand barrier pieces.

[0144] The second method for installing sand barriers is a bidirectional, high-efficiency installation method. It reduces the idle travel and improves operational efficiency through a reciprocating pattern of "forward installation - reverse installation." This demonstrates the necessity of installing material roll support assemblies 3 on the left and right sides of the front end of the fixed frame 11 in Embodiment 1.
