Description

Technical Field

[0001] The utility model belongs to the technical field of windbreak and sand fixation, and specifically relates to a windbreak and sand fixation loose grass paving device. Background Art

[0002] Due to natural and human factors, land desertification has become one of the most harmful natural disasters in the world and one of the most prominent environmental problems. In the work of sand prevention and control, sand barriers are a very important technical measure. Sand barriers, also called wind barriers, are a type of obstacle set up in areas where wind and sand are harmful to change the speed, direction, structure and surface erosion of wind and sand flows. Sand barriers can be divided into living sand barriers and mechanical sand barriers. Living sand barriers refer to plant sand barriers, which are the longest-lasting measures for sand prevention and control. In some areas with harsh natural conditions, where plant sand barriers cannot survive and are in urgent need of control, mechanical sand barriers are very important.

[0003] At present, the construction of sand barriers, especially the laying process of grass grid sand barriers, still relies on manual labor, which is inefficient, labor-intensive, and difficult to adapt to the complex and changeable desert environment. Therefore, developing sand control machinery suitable for sandy areas and realizing the mechanized construction of sand barrier facilities have become an important demand for sand prevention and control work.

[0004] Existing sand control machinery still has some problems in dealing with complex desert environments, improving laying efficiency, and simplifying operating procedures. For example, the operating range of large sand-fixing vehicles is also limited due to complex terrain conditions such as frequent wind and sand activities in sandy areas, large terrain height differences, high degree of fragmentation, and different sizes of areas. Although small-scale grass grid sand barrier laying machinery has improved laying efficiency to a certain extent, its function is single and still requires manual cooperation and operation, and the overall manpower consumption is still very high.

[0005] For this reason, a windbreak and sand-fixing loose grass paving device is urgently needed to solve the above problems. Utility Model Content

[0018] The utility model also includes other components that enable the windbreak and sand fixation loose grass paving device to be used normally, which are all conventional technical means in the field. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the field, such as electric push rods, drum motors, transmission motors, servo motors, hair dryers, DC motors, stepper motors, water pumps, dual-axis motors, single-axis motors, cameras and radars.

[0019] The working principle of the utility model is to first perform trenching operation, and the specific steps are as follows: first, according to the hardness of the sand and the difficulty of breaking the ground, adjust the position of the hinge point of the connecting rod and the positioning hole on the positioning plate to change the depth of the plow tip of the trenching plowboard entering the sand surface, so as to adapt to sand with different hardness; then use the gyroscope to detect the slope of the terrain, and according to different slopes and terrains, control the electric push rod to stretch or shrink the free end, and then adjust the inclination angle of the connecting rod through the positioning plate, so as to adjust the height of the trenching plowboard to prepare for the trenching operation; then start the operation, the moving wheel drives the entire device to move, and the plow tip at the bottom of the trenching plowboard is pressed into the sand under the weight and thrust of the entire device. During the movement, the plow tip will continue to crush and flip the sand, forming a groove suitable for laying grass strips on the sand. In this process, the thrust and speed of the entire device will be adjusted according to the terrain and sand hardness perceived in real time to ensure the flatness and continuity of the groove.

[0020] Then the grass sowing operation is carried out. The steps of the grass sowing operation are as follows: the loose grass is loaded in the loose grass box, and the drum motor is controlled to drive the two drums to rotate. The loose grass falls through the gap between the two drums. The tooth hooks arranged on one of the drums can separate the loose grass and fall evenly onto the conveyor belt. At this time, the conveying motor drives the conveying roller to rotate, driving the conveyor belt to continuously convey the loose grass forward. The loose grass falls onto the sand along the inclined bulk material plate, and is thus evenly spread.

[0021] After the loose grass is laid, the grass strip needs to be compacted, that is, the grass pressing operation is performed. The steps of the grass pressing operation are as follows: control two stepper motors to drive two screws to rotate simultaneously, so that the two slides rise or fall, and then adjust the height of the grass pressing wheel to control the pressure on the grass strip. By adjusting the pressure, it can adapt to the hardness of different sands. In soft sand, greater pressure is required to press the grass strip in, and the moving range of the grass pressing wheel can also be adjusted to meet the needs of grass pressing in different terrain environments and different depths.

[0022] After the grass pressing operation, in order to prevent the loose grass from being blown away by strong wind, spraying operation is required to improve the stability of the soil. The steps of the spraying operation are as follows: the water tank is filled with sand hardener, turn on the water pump, draw the sand hardener to the nozzle and spray it out, and cover and spray the contact points between the roots of the loose grass and the sand and the middle part of the pressed grass. In this way, a hardened film can be formed between the loose grass and the sand, so that the loose grass and the sand can be tightly combined to resist the invasion of strong winds and prevent the loose grass from being blown away. At the same time, it can also protect the moisture of the sand and prevent the moisture from evaporating too quickly, thereby improving the environmental conditions of the sand and being conducive to the growth of vegetation.

[0023] In the above series of treatments for loose grass, sowing operations are also required. The steps of sowing operations are as follows: the grass seed box is filled with grass seeds. Initially, to prevent leakage, the first leakage hole on the bottom plate of the grass seed box and the second leakage hole on the plug plate are staggered by 1 cm. After the sowing operation begins, the servo motor drives the gear to rotate, which in turn drives the plug plate to move horizontally along the slide slot, so that the first leakage hole on the bottom plate and the second leakage hole on the plug plate are aligned with each other, so that the grass seeds can pass through the leakage holes; then the fallen grass seeds fall onto the receiving table, and the hair dryer is started to blow the grass seeds out of the receiving table and sow them on the sand. In order to make the grass seeds fall quickly, the agitator can be started to disturb the grass seeds, break the balance between the grass seed particles, reduce the friction between the particles, and speed up the falling of the materials.

[0024] In addition, the combination of camera and radar realizes the functions of obstacle avoidance and autonomous route planning, allowing the device to navigate and work independently in complex environments.

[0025] The beneficial effects of the utility model are:

[0026] 1) This device integrates the functions of trenching, grass transportation, grass laying, and grass pressing, which overcomes the limitation that large grass grid laying vehicles cannot operate deep in the heart of the desert, and also solves the problem that small grass grid laying vehicles are not comprehensive in function. This design enables the vehicle to carry out comprehensive and efficient operations in complex desert terrain, greatly improving the efficiency of sand fixation. In addition, through the trenching mechanism, the triangular structure formed by the hinge between the electric push rod, the positioning plate and the connecting rod is used to adjust the trenching depth, so that the vehicle can perform precise trenching operations under different sand hardness, improving the accuracy and efficiency of the operation. The grass sowing mechanism can break up the scattered grass gathered during the transmission process, avoiding the problem of uneven laying of the scattered grass due to excessive concentration during the transmission process.

[0027] 2) The sowing mechanism replaces the traditional manual sowing and achieves a continuous sand fixation effect by simulating the spreading process of grass seeds in nature.

[0028] 3) The spray mechanism solves the problem of loose sand after grooving and the loose grass being separated from the ground in strong winds. By adding an environmentally friendly sand-fixing agent to the water tank and spraying it evenly on the junction of the loose grass and sand, a close connection between the loose grass and sand is achieved, simplifying the traditional soil-gathering procedure and achieving the purpose of environmental protection and terrain environment protection.

In soft sand, a greater pressure is required to press the grass strip in, and the moving range of the grass pressing wheel 26 can also be adjusted to meet the grass pressing needs in different terrain environments and different depths.

[0052] After the grass pressing operation, in order to prevent the loose grass from being blown away by strong wind, spraying operation is required to improve the stability of the soil. The steps of the spraying operation are as follows: the water tank 27 is filled with sand hardener, and the water pump is turned on to draw the sand hardener to the nozzle 29 and spray it out, covering and spraying the contact point between the roots of the loose grass and the sand and the middle part of the pressed grass.

Initially, to prevent leakage, the first leakage hole on the bottom plate 15 at the bottom of the grass seed box 14 and the second leakage hole on the plug plate 18 are staggered by 1 cm. After the sowing operation begins, the servo motor 17 drives the gear 19 to rotate, thereby driving the plug plate 18 to move laterally along the slide, so that the first leakage hole on the bottom plate 15 and the second leakage hole on the plug plate 18 are aligned with each other, so that the grass seeds can pass through the leakage hole; then the fallen grass seeds fall onto the receiving platform 21, and the hair dryer 20 is started to blow the grass seeds out of the receiving platform 21 and sow them on the sand.
