Description

Technical Field

[0001] The invention belongs to the technical field of sand control equipment, and particularly relates to a grass grid paving machine. Background Art

[0002] Desertification is caused by excessive human pursuit of economic activity, which leads to the destruction of ecosystems and the resulting environmental changes that create desert-like landscapes in non-desert areas. Land desertification is a sign of environmental degradation and a positive feedback loop that contributes to environmental instability. Without fundamental measures, wind erosion and desertification will not only not stop on its own, but will actually intensify.

[0003] Currently, one of the national measures to combat desertification is the installation of sand barriers, including straw grid sand barriers and clay sand barriers. Straw grid sand barriers, made of materials such as wheat straw, rice straw, and reeds, form windbreaks on shifting sand dunes to mitigate wind erosion and trap rainfall, increasing the water content of the sand layer and promoting the growth of sand-dwelling plants.

[0004] The traditional straw grid laying technique is still widely used in my country. The main steps in making a straw grid are sorting the straw, placing it, and pressing it into shape. Wearing gloves, workers grab an appropriate amount of straw and swish it against the wind, knocking off the broken and shorter straw, leaving only the long straw suitable for forming the straw grid. After sorting the straw, workers place it along the marked squares, maintaining a consistent thickness. Finally, they use a shovel to press the straw down firmly along the squares. The force of the shovel causes the straw to naturally rise up on both sides, forming a natural straw barrier. Once the straw is upright, workers press the surrounding soil down to the base of the straw to strengthen its stability. Straw grid sand barriers require significant labor and resources, and the laying process is labor-intensive. Maintenance is also required, and the straw selection and shaping process requires manual labor.

[0005] Ningxia currently uses a brush-net-rope grass grid sand barrier technology for sand control. Workers use specialized grass grid sand barrier material production equipment to pre-assemble the grass ropes and brush mats, creating a specific quantity of brush net ropes. Once completed, the net ropes are loaded onto trucks and transported to the desired area. During the grass grid production process, workers work in teams of two, laying the prepared brush net ropes in 1m x 1m sections on the sand. An 8m² grass grid sand barrier can be constructed in just three minutes. Compared to traditional grass grid sand barrier production, the net rope sand barrier only requires fixing the edges, with ropes used to secure the net ropes at their intersections. While this method improves production efficiency and reduces costs, it still requires a certain amount of manpower.

[0006] Compared to semi-automated machinery, straw mat laying robots significantly reduce labor costs. Their mechanical structure also ensures the effectiveness of the straw grid sand barrier in preventing sand, reducing subsequent maintenance. The straw mat laying robot primarily consists of a tractor, a longitudinal laying mechanism, and a transverse laying mechanism. The desert vehicle provides traction, while the longitudinal and transverse laying mechanisms perform the task of laying the straw grid. This robot automates the production and fabrication of straw grid sand barriers, but requires repeated pauses during the laying process. While this improves efficiency and saves labor compared to traditional methods, the results are still unsatisfactory. A better solution is needed to achieve both labor savings and higher efficiency.

[0038] like Figures 1 to 3 As shown, the present invention relates to a grass grid paving machine 100 for automatically cutting straw mats and pressing them into sand, significantly saving labor and improving paving efficiency and quality. The grass grid paving machine 100 can be equipped with a self-propelled mechanism to achieve a walking function, or it can be connected to a tractor via a trailer hook 200 and paved in a predetermined direction under the traction of the tractor.

[0039] The grass grid paving machine 100 includes a chassis 10, a windproof and sandproof cover 20, a straw mat platform 30, a feeding mechanism 40, a cutting mechanism 50 and a rolling mechanism 60. The chassis 10 and the windproof and sandproof cover 20 define a cavity, and the straw mat platform 30, the feeding mechanism 40, the cutting mechanism 50 and the rolling mechanism 60 are all located in the cavity.

[0040] Traveling wheels 101 are provided at the corner ends of the chassis 10 , and the traveling wheels 101 are preferably rollers, which facilitate the grass grid paving machine 100 to move on the sand.

[0041] The straw mat platform 30 is fixed above the chassis 10. It has a flat surface and two guide ramps 32 connected at either end. The flat surface is used to lay the straw mat on, and the guide ramps 32 guide the direction of movement of the straw mat to ensure smooth transportation and unfolding. A straw pressing groove 31 is defined in the middle of the width of the straw mat platform 30. The groove is 100 mm wide and extends along the length of the straw mat platform 30.

[0042] In one embodiment, the feeding mechanism 40 includes a roller 41 and a driving motor for driving the roller 41 to rotate. The axial direction of the roller 41 is the same as the travel direction of the grass grid paving machine 100. The finished straw mat 80 is wound on the roller 41. The roller 41 is arranged above the guide slope 32 and can be rotated to make the straw mat fall onto the guide slope 32 and unfold along the plane.

[0043] The cutting mechanism 50 is disposed above the straw mat platform 30 and near the roller 41 for cutting the straw mat thread and cutting the desired straw mat segments from the finished straw mat 80. The cutting mechanism 50 includes a cutting blade 52 and a cutting cylinder 51 for driving the cutting blade 52 to move upward and downward.

[0044] The rolling mechanism 60 is used to press the cut straw mat segments into the sand, completing the laying of the grass grid. The rolling mechanism 60 includes rolling wheels 66, which can be driven through the grass pressing groove 31 to roll and press the straw mat segments into the sand. The rolling wheels 66 move perpendicular to the direction of travel of the grass grid paving machine 100 (or the traction direction if the grass grid paving machine 100 is being towed).

[0045] In one embodiment, two feeding mechanisms 40 are provided, and the two feeding mechanisms 40 are arranged in a direction perpendicular to the traveling direction, that is, the two feeding mechanisms 40 are provided on the left and right sides of the traveling direction. Two cutting mechanisms 50 are provided, and are respectively provided near the two rollers 41.

[0046] Please combine Figures 4 and 5 :

[0047] In one embodiment, oppositely arranged fixing mechanisms 70 are provided on both sides of the top of the windproof and sandproof cover 20, and the fixing mechanisms 70 include two oppositely arranged fixing rods 71, a rotatable rotating shaft 72 is mounted on the fixing rod 71, and the finished straw mat 80 is wound on the rotating shaft 72, and a feeding trough 21 connected to the cavity is opened on both sides of the windproof and sandproof cover 20, and the straw mat passes through the feeding trough 21 and extends into the cavity to be connected to the feeding mechanism 40.

[0048] In one embodiment, the feeding mechanism 40 is arranged at both sides of the straw mat platform 30, and each feeding mechanism 40 is provided with two rollers 41, and a feeding gap for the straw mat to pass through is formed between the two rollers 41, and the guide slope 32 is formed on the lower roller 41 in the direction toward the cutting mechanism 50.

[0049] There are two rolling wheels 66, and the rolling mechanism 60 also includes a screw rod 62, a slider 63, a rolling cylinder 64 and a connecting rod mechanism 65. The screw rod 62 is perpendicular to the roller 41 and connected between the two cutting mechanisms 50. The slider 63 is sleeved on the screw rod 62 and can slide along the screw rod 62. The rolling cylinder 64 is rotatably provided on the slider 63. The connecting rod mechanism 65 is connected to the piston rod of the rolling cylinder 64. The two rolling wheels 66 are connected to the connecting rod mechanism 65 and the line between the two rolling wheels 66 and the connecting rod mechanism 65 is perpendicular. The screw rod 62 can be driven forward or reverse by a mobile motor 67 connected to it to drive the slider 63 to slide left or right. The connecting rod mechanism 65 can be driven by the rolling cylinder 64 to realize the switching of the two rolling wheels 66. Through the alternating operation of the two rolling wheels and the reciprocating motion of the screw slider, seamless connection between the grass grids is achieved, which improves the laying efficiency of the grass grids while ensuring the laying quality of the grass grids.

[0050] When in use, a hinge block is provided at the top of the rolling cylinder 64, and the hinge block is hinged to the slider 63. At this time, the piston rod of the rolling cylinder 64 is in a retracted state;

[0051] Please combine Figure 5 When the piston rod of the rolling cylinder 64 is fully retracted, the rolling cylinder 64 is inclined relative to the travel direction of the slider 63. At this time, the rolling wheel 66 connected to the connecting rod mechanism 65 is parallel to the travel direction of the slider 63, and the other rolling wheel 66 is perpendicular to the travel direction of the slider 63.

[0052] Please combine Figure 6When the piston rod of the rolling cylinder 64 begins to extend, the rolling cylinder 64 rotates along the hinge between the rolling cylinder 64 and the slider 63 in a direction perpendicular to the moving direction of the slider 63. At the same time, the piston rod of the rolling cylinder 64 drives the connecting rod mechanism 65 to rotate, and the connecting rod mechanism 65 drives the two rolling wheels 66 to rotate.

[0053] Please combine Figure 7 When the piston rod of the rolling cylinder 64 is fully extended, the rolling cylinder 64 rotates along the hinge between the rolling cylinder 64 and the slider 63 in a direction perpendicular to the moving direction of the slider 63 until it is perpendicular to the moving direction of the slider 63, or close to perpendicular, or still inclined. At this time, the rolling wheel 66 connected to the connecting rod mechanism 65 rotates to be perpendicular to the moving direction of the slider 63, and the other rolling wheel 66 rotates to be parallel to the moving direction of the slider 63.

[0054] Preferably, the grass grid paving machine 100 also includes a straw length detection component, which includes two spaced-apart sensors (not shown, the same below). Both sensors are located between the two rollers 41 and output an electrical signal indicating that the straw length meets the requirements when the straw passes through the two sensors in succession. In this way, the unfolded length of the straw can be automatically identified, so that the length of the cut straw segments is the same, improving consistency and thus improving the grass grid paving effect. Preferably, both sensors are ultrasonic sensors, which can be located on or above the straw platform. The spacing between the two sensors can be set according to the length of the straw segment to be cut. In this embodiment, the spacing between the two sensors is one meter.

[0055] The cutting cylinder 51 is fixed to the wind and sand protection cover 20, and the screw rod 62 is fixed to the bottom of the wind and sand protection cover 20 through the mounting block 61. By providing the wind and sand protection cover 20, the wind and sand protection function can be achieved, the internal mechanism of the grass grid paving machine is protected, and the service life is extended. It also provides a fixed position for the cutting mechanism 50 and the rolling mechanism 60, facilitating the structural configuration of the grass grid paving machine 100.

[0056] This embodiment Figures 1 to 3 The grass grid paving machine shown can protect the finished straw curtain 80 when in use. Figures 4 to 7 The grass grid paving machine shown can facilitate the disassembly and assembly of the finished straw mat 80.

[0057] Please combine Figure 8a-8d In the present invention, the working principle of the grass grid paving machine 100 is as follows:

[0058] Assume that in the initial state, slider 63 is located to the left of straw mat platform 30, and rolling cylinder 64 is retracted. At this point, the right-side feeding mechanism 40 is activated, the motor starts, and straw mat is spread flat on straw mat platform 30. When the sensor detects that the straw mat on straw mat platform 30 has reached 1 meter, it sends a signal, and the right-side cutting mechanism 50 activates, shearing the straw mat (i.e., cutting out a 1-meter-long section). Simultaneously, the piston rod of rolling cylinder 64 extends, and connecting rod mechanism 65 activates, causing a rolling wheel 66 to press the straw mat section down into the sand by 15 to 25 mm. The straw grid paving machine 100 then moves forward at a speed v2 and in a downward direction. Simultaneously, screw 62 activates, and rolling wheel 66 moves at a speed v1 and in a rightward direction. Screw 62 drives connecting rod mechanism 65, laying a 1-meter-long row of hay on the ground at a 45° angle to the direction of movement of the straw grid paving machine 100.

[0059] As screw 62 is activated, the feed mechanism 40 on the left side of the straw mat platform 30 begins to operate, spreading the straw mat onto the straw mat platform 30 from the left. When screw 62 moves to the right side of the straw mat platform 30, the feed mechanism 40 on the left side has just laid out a one-meter-long straw mat on the straw mat platform 30. The cutting mechanism 50 on the left side then activates, shearing the straw mat. Simultaneously, the connecting rod 65 activates, causing the piston rod of the rolling cylinder 64 to retract, switching to the other rolling wheel 66 to press the straw mat down 15 to 25 mm into the sand. Screw 62 then reverses, and the connecting rod 65 moves to the left, laying a one-meter-long row of hay on the ground at a 135° angle to the direction of motion of the grass grid paving machine 100.

[0060] By repeating the above movement process, a 1m×1m grass grid is laid on the ground, such as Figure 8d When the straw mat on the roller 41 in the feeding mechanism 40 is used up, the straw mat can be quickly replaced by directly replacing the roller 41.

[0061] Compared with the existing grass grid laying technology, first of all, the straw mat laying robot needs two blades, one horizontal and one vertical, which is an intermittent laying method. The grass grid paving machine 100 of the present invention only uses one rolling mechanism 60 to realize the production of grass grid sand barriers in both the horizontal and vertical directions, which is a continuous laying method and can improve the laying efficiency. In addition, the horizontal blade and the vertical blade of the straw mat laying robot need to be frequently lifted and lowered. In order not to affect the laying of the grass grid sand barrier, the shorter the time for lifting and lowering the blade, the better. However, increasing the speed will bring a certain impact force to the machine itself, which is not conducive to long-term use. The grass grid paving machine 100 of the present invention uses a rolling cylinder 64 to drive the connecting rod mechanism 65 to rotate and switch the two rollers, which has basically no impact force on the tractor and extends the service life of the paving machine.

[0062] Secondly, the straw mat laying robot needs to stop every meter during operation. Frequent starts and stops will increase errors and cause the driver to sway back and forth due to inertia, causing physical discomfort and hindering work. The fully automatic straw grid paving machine of the present invention does not need to stop during operation, which can reduce the driver's discomfort and improve the laying efficiency.

[0063] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quoting of drawings which would result in a less concise description, features that have been described clearly will not be quoted from the drawings one by one.

[0064] The purpose of the above embodiments is to exemplify and deduce the technical solution of the present invention, and to fully describe the technical solution, purpose and effect of the present invention. Its purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of the present invention, and it does not limit the scope of protection of the present invention.

[0065] The above embodiments are not exhaustive and may include many other embodiments not listed above. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
