Description

Technical Field

[0001] The utility model relates to the technical field of desert environment management, in particular to a multifunctional grass grid paving and pressing integrated machine. Background Art

[0002] Stabilizing shifting sand dunes is a crucial component of sand control and prevention projects. On the one hand, due to their high mobility and significant hazards, effective management and control are essential. On the other hand, shifting sand dunes contain relatively high moisture content, but they are subject to severe wind erosion, making artificial vegetation difficult to maintain and maintain. Therefore, implementing effective technical measures to control wind erosion in shifting sand dunes and effectively reducing the depth of wind-eroded concavities between sand barriers are crucial for establishing vegetation and controlling the hazards of shifting sand dunes. Sand barriers are the most commonly used and effective technical measure in sand control and prevention projects, playing a particularly important role in managing shifting sand dunes and restoring vegetation. Currently, commonly used sand fixation measures include straw grids, branch sand barriers, sand fences, clay grids, gravel grids, and clay burials. Straw grid sand barriers are constructed using materials such as wheat straw and rice straw, arranged in a grid-like pattern on shifting sand dunes to mitigate wind erosion. On exposed shifting and semi-shifting dunes, wheat straw sand barriers of the appropriate design specifications are used. During construction, a construction grid is first drawn on the dunes, ensuring the barrier is perpendicular to the prevailing wind direction. According to the construction drawings, the toe line, platform control points, and other elements are measured and laid out. Following the design specifications for the sand barrier, the lines are laid out along the dune contours. The grid-like sand barrier is also laid out perpendicular to the dune contours, forming a complete, closed grid. This effectively increases the success rate and preservation rate of afforestation in the sandy land.

[0003] The inventors have found that the existing grass grid sand barrier installation measures have at least the following disadvantages:

[0004] Currently, some mechanical devices on the market can only complete the process of pressing straw into the sand, and the initial straw laying process relies entirely on manual labor. Manual laying is the main method, and equipment-assisted straw pressing still has problems such as heavy workload, slow speed, low efficiency, and high cost. Utility Model Content

[0005] The purpose of the utility model is to provide a multifunctional grass grid paving and pressing integrated machine, which can improve the degree of automation and realize automatic grass paving and pressing at the same time, with low labor intensity, high speed, high efficiency and low cost.

[0006] The embodiment of the present utility model is achieved as follows:

[0007] In a first aspect, the utility model provides a multifunctional grass grid paving and pressing machine, comprising:

[0008] A vehicle frame, a traveling mechanism, a grass-laying mechanism and a grass-pressing mechanism; the traveling mechanism is mounted on the vehicle frame for driving the vehicle frame to move; the grass-laying mechanism and the vehicle frame are both mounted on the vehicle frame, the grass-laying mechanism is provided with a storage chamber and a discharge port connected to the storage chamber, the storage chamber is used for storing grass to be laid, and the discharge port is used for discharging the grass to be laid to the ground; the grass-pressing mechanism is used for pressing the grass to be laid that has fallen on the ground into the ground.

[0009] In an optional embodiment, the walking mechanism includes a power assembly and walking wheels, the power assembly is mounted on the frame, the walking wheels are rotatably mounted on the frame, and the power assembly is transmission-connected to the walking wheels for driving the walking wheels to rotate.

[0010] Based on the above scheme, after the powertrain is started, it can transmit power to the traveling wheels, thereby driving the frame to move through the traveling wheels, and can lay grass and other materials on the set route to realize automatic grass laying. At the same time, when the frame is moving, the grass pressing mechanism moves with the frame, and can compact the materials laid on the sand, so that the materials are pressed into the sand to a set depth.

[0011] In an optional embodiment, the power assembly includes a diesel engine, a reducer and a transmission assembly, the diesel engine and the reducer are both installed on the frame, the diesel engine is connected to the reducer in a transmission manner, and the reducer is connected to the walking wheel through the transmission assembly.

[0012] Based on the above scheme, power output is achieved through the combination of a diesel engine and a reducer, which makes it easy to control the rotation speed of the walking wheels, thereby controlling the travel speed of the frame, and making the operation convenient and flexible.

[0013] In an optional embodiment, the transmission assembly is configured as a chain transmission structure or a belt transmission structure.

[0014] Based on the above solution, the transmission component has a simple structure, is easy to assemble, operates stably and reliably, has a long service life and is low in cost.

[0015] In an optional embodiment, the grass-laying mechanism includes an outer frame and two conveyor belt assemblies, the outer frame is mounted on the vehicle frame, and the outer frame is provided with the storage cavity; the two conveyor belt assemblies are both mounted on the outer frame and located in the storage cavity, and there is a distance between the two conveyor belt assemblies to form the drop-out port; the two conveyor belt assemblies are used to rotate towards each other to output the laid grass from the drop-out port.

[0016] Based on the above solution, by placing the material in the storage chamber, the two conveyor belt assemblies move simultaneously as the vehicle frame advances, rotating in opposite directions. This means that both conveyor belt assemblies can convey the material located thereon toward the dropout opening. When the material reaches the dropout opening, it loses the support of the conveyor belt assemblies and, under the action of gravity, falls from the dropout opening onto the sand. The grass pressing mechanism then passes over the material laid on the sand, compacting the material and pressing it to a set depth. The coordinated material conveying of the two conveyor belt assemblies is highly efficient, less prone to clogging, and operates stably and reliably.

[0017] In an optional embodiment, the conveyor belt assembly includes a conveyor belt body and a plurality of rollers arranged in parallel, and the plurality of rollers can be rotatably mounted on the outer frame, and the conveyor belt body is tensioned by all of the rollers at the same time; the position of at least one of the plurality of rollers relative to the outer frame is adjustable to adjust the tension of the conveyor belt body.

[0018] Based on the above solution, multiple rollers cooperate to support the conveyor belt body, maintaining a stable shape. Adjusting the position of the rollers as needed allows for adjustments to both the belt's tension and the width of the dropout opening, thereby adjusting the width of the straw bedding. This provides flexibility and convenience. Specifically, one of the multiple rollers is positioned at the dropout opening, and the edge of the conveyor belt body is determined by the position of this roller. Increasing the distance between the two rollers adjusts the dropout opening width, increasing the straw bedding width. Conversely, the straw bedding width can be reduced.

[0019] In an optional embodiment, each of the conveyor belt bodies is provided with a conveying surface, and the conveying surfaces of the two conveyor belt bodies are arranged at an angle.

[0020] Based on the above solution, the conveying surfaces of the two conveyor belt bodies are set at an angle, so that the material has a tendency to slide toward the drop port under the action of gravity. The material can always slide toward the drop port and is not easy to slip with the conveyor belt body, thereby improving the material conveying efficiency.

[0021] In an optional embodiment, each of the conveying surfaces is provided with a feeding side close to the drop port, each of the conveying surfaces has an angle with the horizontal plane, and the height of the feeding side of the conveying surface with a larger angle with the horizontal plane is lower than the feeding side of the other conveying surface.

[0022] Based on the above solution, material transportation is more orderly and the material outlet is not easily blocked.

[0023] In an optional embodiment, the walking mechanism and the grass-laying mechanism share a power assembly.

[0024] Based on the above solution, grass is laid while the frame is moving, the grass laying action is continuous, and the thickness of the grass is more uniform.

[0025] In an optional embodiment, a handrail is installed on the frame.

[0026] Based on the above solution, the direction of the frame is stabilized by the handrail, so that the frame can move along the set route and operate reliably.

[0027] The beneficial effects of the embodiments of the present utility model are:

[0028] To sum up, the multifunctional grass grid paving and pressing machine provided in this embodiment integrates a grass paving mechanism and a grass pressing mechanism on the frame at the same time. When the frame moves under the drive of the traveling mechanism, the material in the storage chamber falls from the material dropout port under the action of the grass paving mechanism and is laid on the sand. Then, the grass pressing mechanism passes through the material laid on the sand and presses the material into the sand to a set depth. In this way, the automated operations of grass paving and grass pressing are realized at the same time, with low labor intensity, high efficiency and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0038] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0041] In the prior art, to combat desertification, straw grids are generally used for sand fixation. To make the straw grids, a layer of materials such as wheat straw or rice straw must be manually laid on the sand. The materials are then compacted manually or mechanically to a depth that is consistent with the depth of the sand. The manual laying of materials results in high labor intensity, low efficiency, and high costs.

[0042] In view of this, the designer provides a multifunctional grass grid paving and pressing machine, which can realize the integrated operation of grass paving and pressing at the same time, reduce labor intensity, improve work efficiency and reduce operation costs.

[0043] Please combine Figure 1-Figure 3 In this embodiment, the multifunctional grass grid paving and pressing machine includes a frame 100, a traveling mechanism 200, a grass laying mechanism 300 and a grass pressing mechanism 400; the traveling mechanism 200 is installed on the frame 100, and is used to drive the frame 100 to move; the grass laying mechanism 300 and the frame 100 are both installed on the frame 100, and the grass laying mechanism 300 is provided with a storage chamber 301 and a discharge port 302 connected to the storage chamber 301, the storage chamber 301 is used to store the grass to be laid, and the discharge port 302 is used to discharge the grass to be laid to the ground; the grass pressing mechanism 400 is used to press the grass to be laid that falls on the ground into the ground.

[0044] Based on the above solution, the multifunctional grass grid paving and pressing machine provided in this embodiment works as follows:

[0045] By integrating the grass-laying mechanism 300 and the grass-pressing mechanism 400 on the vehicle frame 100, when the vehicle frame 100 moves under the drive of the traveling mechanism 200, the material in the material storage chamber 301 falls from the drop-out port 302 under the action of the grass-laying mechanism 300 and is laid on the sand. Then, the grass-pressing mechanism 400 passes through the material laid on the sand and presses the material into the sand to a set depth. In this way, the automated operations of grass-laying and grass-pressing are realized at the same time, with low labor intensity, high efficiency and low cost.

[0046] The following embodiments illustrate the details of the multifunctional grass grid paving and pressing machine provided in this application by way of examples.

[0047] Please combine Figure 1 or Figure 2In this embodiment, optionally, the traveling mechanism 200 includes a powertrain 210 and traveling wheels 220. The powertrain 210 is mounted on the vehicle frame 100, and the traveling wheels 220 are rotatably mounted on the vehicle frame 100. The powertrain 210 is in transmission connection with the traveling wheels 220 to drive the traveling wheels 220 to rotate. It should be understood that the powertrain 210 can be mounted at the rear of the vehicle frame 100 in the direction of travel, and the number of traveling wheels 220 can be four, wherein two traveling wheels 220 share a rotating shaft 230, and the rotating shaft 230 is rotatably engaged with the vehicle frame 100. The traveling wheels 220 located at the rear of the vehicle frame 100 in the direction of travel can be driving wheels, which are connected to the powertrain 210 and driven by the powertrain 210. The two traveling wheels 220 located at the front of the vehicle frame 100 in the direction of travel can be driven wheels, which rotate passively only under friction. During actual operation, the power assembly 210 is started and can transmit power to the rear running wheels 220, thereby driving the frame 100 to move through the running wheels 220, and can lay grass and other materials on the set route to achieve automatic grass laying. At the same time, when the frame 100 is moving, the grass pressing mechanism 400 moves with the frame 100, and can compact the materials laid on the sand, so that the materials are pressed into the sand to a set depth.

[0048] Optionally, the powertrain 210 includes a diesel engine 211, a speed reducer 212, and a transmission assembly 213. The diesel engine 211 and the speed reducer 212 are both mounted on the vehicle frame 100. The output shaft of the diesel engine 211 is in driving connection with the input shaft of the speed reducer 212. The output shaft of the speed reducer 212 is connected to the rotating shaft 230 of the rear running wheel 220 via the transmission assembly 213. The combination of the diesel engine 211 and the speed reducer 212 enables power output, facilitates control of the rotation speed of the running wheel 220, and thus controls the travel speed of the vehicle frame 100, providing convenient and flexible operation.

[0049] It should be understood that the diesel engine 211 and the speed reducer 212 can be arranged independently and spaced apart, and connected together by a transmission belt or the like to achieve torque transmission. By arranging the diesel engine 211 and the speed reducer 212 on the rear side of the vehicle frame 100, the weight of the rear side of the vehicle frame 100 is increased, which can help to compact the materials laid on the sand.

[0050] Please combine Figure 2It should be noted that the transmission assembly 213 is configured as a chain transmission structure or a belt transmission structure. The transmission assembly 213 has a simple structure, is easy to assemble, operates stably and reliably, has a long service life, and has a low cost of use. For example, when the transmission assembly 213 is configured as a chain transmission structure, a sprocket body is sleeved on the rotating shaft 230 installed on the traveling wheel 220 and on the output shaft of the speed reducer 212. Then, the corresponding sprocket bodies are connected by a chain. After the speed reducer 212 rotates, the sprocket body connected to the output shaft of the speed reducer 212 rotates, and power can be transmitted to the rotating shaft 230 through the chain, thereby driving the traveling wheel 220 to rotate.

[0051] Optionally, the grass pressing mechanism 400 includes a grass pressing wheel, which can be installed on the rear side of the frame 100 through a positioning shaft. The grass pressing wheel and the positioning shaft are rotatably matched through bearings, and the diameter of the grass pressing wheel is larger than the diameter of the walking wheel 220. The lowest point of the grass pressing wheel is 10-15 cm lower than the lowest point of the walking wheel 220. In this way, after the grass pressing wheel presses the material, it can press the material into the sand 10-15 cm, and the depth of the material pressed into the sand can be set as needed.

[0052] Please combine Figure 1-Figure 3 In this embodiment, the grass-laying mechanism 300 optionally includes an outer frame 310 and two conveyor belt assemblies 320. The outer frame 310 is mounted on the vehicle frame 100. The outer frame 310 and the vehicle frame 100 can be fixedly connected using fasteners such as welding or bolts. The outer frame 310 is provided with a storage chamber 301. The top of the storage chamber 301 is open. The top of the outer frame 310 is hinged with two cover plates 330. The two cover plates 330 cooperate to close the opening at the top of the storage chamber 301, acting as a protective material. The two conveyor belt assemblies 320 are both mounted on the outer frame 310 and located within the storage chamber 301. There is a spacing between the two conveyor belt assemblies 320 in the direction of travel of the vehicle frame 100 to form a blanking opening 302. The blanking opening 302 is a strip-shaped hole, and the length of the blanking opening 302 extends in the width direction of the vehicle frame 100. The two conveyor belt assemblies 320 are used to rotate towards each other to output the belt-laid grass from the drop port 302 , that is, the two conveyor belt assemblies 320 can transport the material to the drop port 302 so that the material falls from the drop port 302 .

[0053] It should be understood that by placing the material in the storage chamber 301, as the vehicle frame 100 advances, the two conveyor belt assemblies 320 move simultaneously, rotating toward each other. That is, both conveyor belt assemblies 320 can convey the material located thereon toward the dropout 302. When the material is located at the dropout 302, it loses the support of the conveyor belt assemblies 320 and, under the action of gravity, falls from the dropout 302 onto the sand. The grass pressing mechanism 400 then passes over the material laid on the sand, compacting the material and pressing it to a set depth. The coordinated material conveying by the two conveyor belt assemblies 320 is highly efficient, less prone to clogging, and operates stably and reliably.

[0054] It should be noted that the conveyor belt assembly 320 can be powered by the power assembly 210 of the traveling mechanism 200. Advantageously, the power can be transmitted to the speed belt assembly through the rotating shaft 230 in conjunction with the chain drive structure or the belt drive structure.

[0055] Optionally, the conveyor belt assembly 320 includes a conveyor belt body 321 and a plurality of rollers 322 arranged in parallel. The plurality of rollers 322 are rotatably mounted on the outer frame 310, and the conveyor belt body 321 is simultaneously tensioned by all the rollers 322. The position of at least one of the plurality of rollers 322 relative to the outer frame 310 is adjustable to adjust the tension of the conveyor belt body 321. For example, in this embodiment, the number of rollers 322 supporting the same conveyor belt body 321 is three, wherein the three rollers 322 are arranged in parallel and located at the three vertices of a triangle. One of the rollers 322 can be connected to the rotating shaft 230 via the transmission assembly 213, outputting the torque of the power assembly 210 to the roller 322, thereby driving the conveyor belt body 321 to move.

[0056] It should be understood that the multiple rollers 322 cooperate to support the conveyor belt body 321, maintaining a stable shape. Adjusting the position of the rollers as needed allows for adjustments to both the tension of the conveyor belt body 321 and the width of the drop-out opening 302, thereby adjusting the width of the grass, making it flexible and convenient to use. Specifically, one of the multiple rollers 322 is positioned at the drop-out opening 302, and the edge of the conveyor belt body 321 is determined by the position of this roller 322. Increasing the distance between the two rollers 322 adjusts the width of the drop-out opening 302, increasing the width of the grass. Conversely, the grass width can be reduced.

[0057] Furthermore, each conveyor belt body 321 is provided with a conveying surface, and the conveying surfaces of the two conveyor belt bodies 321 are arranged at an angle. The angled conveying surfaces of the two conveyor belt bodies 321 cause the material to slide toward the material dropout 302 under the action of gravity. The material can always slide toward the material dropout 302 and is not likely to slip on the conveyor belt bodies 321, thereby improving material conveying efficiency.

[0058] Furthermore, each conveying surface is provided with a feeding side proximate to the material dropout 302. Each conveying surface is angled with respect to the horizontal plane. The feeding side of the conveying surface with the larger angle with respect to the horizontal plane is lower than the feeding side of the other conveying surface. This allows for more orderly material transportation and reduces the risk of clogging the material dropout 302.

[0059] It should be understood that in other embodiments, each conveyor belt assembly 320 can be independently powered. For example, each conveyor belt assembly 320 can be independently powered. The motor drives at least one roller 322 to rotate, thereby achieving torque output. Alternatively, two conveyor belt assemblies 320 can share a motor, which transmits power to the rollers 322 of the two conveyor belt assemblies 320 via a chain drive structure or a belt drive structure, thereby achieving power transmission. In addition, the motor can be mounted on the side of the outer frame 310, and the output shaft of the motor can be directly connected to the corresponding roller 322.

[0060] In this embodiment, optionally, a handrail 110 is installed on the front side of the frame 100. The handrail 110 stabilizes the direction of the frame 100 so that the frame 100 can travel along a set route and operate reliably.

[0061] The multifunctional grass grid paving and pressing machine provided in this embodiment integrates a grass paving mechanism 300 and a grass pressing mechanism 400. The grass paving mechanism 300 automatically spreads the grass, and the grass pressing mechanism 400 presses the spread grass on the sand, thereby realizing automatic grass paving and pressing with low labor intensity and high efficiency.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
