Description

A pretreatment device for preventing and controlling wind erosion of desertified soil

Technical Field

The invention relates to the technical field of wind erosion prevention and control, and in particular to a pretreatment device for preventing and controlling wind erosion of desertified soil.

Background Art

Wind erosion is a common soil erosion phenomenon, mainly caused by soil movement under the action of wind. Wind erosion will carry away the surface soil, resulting in a large loss of nutrients and organic matter in the soil, which will reduce soil quality, cause crops to fall, and cause trees to break, flowers and fruits to fall, directly affecting the growth of crops and forestry production efficiency, and having a great negative effect on agriculture and forestry. Therefore, taking effective measures to prevent and control wind erosion is of great significance to maintaining the ecological environment and the sustainable development of agriculture and forestry.

Publication No.: CN217721955U discloses an irrigation device for repairing desertified soil. By providing a No. 1 motor and a stirring blade, the mixing of the medicine and water inside the liquid storage tank can be better promoted, thereby improving the repair effect of the medicine on the soil. By providing a soil turning mechanism, the soil turning mechanism consists of an electric telescopic rod, a support plate, a soil turning wheel, an equipment box, a driven roller, a No. 2 motor, a driving gear, a driven gear and a driving shaft. The No. 2 motor can be used to drive the soil turning wheel to work, so that the soil can be turned, which is convenient for the upper and lower layers of the soil to absorb the medicine, thereby improving the repair effect.

However, after the above-mentioned device turns the soil, it is inconvenient to level the desertified soil after turning the soil. Soil leveling has a good effect on soil conservation, water conservation, fertilizer conservation, alkali prevention and seedling conservation, mechanized farming and saving irrigation water. The leveled soil will be more suitable for agricultural cultivation. However, if the soil is not leveled after turning the soil, the surface of the desertified soil will be uneven, which may easily cause water accumulation on the soil surface, which is not conducive to the planting and growth of crops. In addition, the uneven surface is not conducive to the smooth transfer of wind and sand, and is prone to sand accumulation, which makes it impossible to effectively prevent and control wind erosion.

Therefore, it is necessary to provide a pretreatment device for preventing and controlling wind erosion of desertified soil to solve the above technical problems.

Second embodiment:

Please refer to Figures 1 and 8 to 11. A fertilizing mechanism 5 is provided at the front side of the top of the mounting frame 1. The fertilizing mechanism 5 includes a fertilizer hopper 51 fixedly provided at the front side of the top of the mounting frame 1. A fertilizing roller 52 is provided on the inner side of the top of the mounting frame 1 and at the bottom of the fertilizer hopper 51 for transverse rotation. A first pulley 53 is fixedly provided at the right end of the fertilizing roller 52 and at the right side of the mounting frame 1. A second pulley 54 is fixedly provided at the right end of the rotating roller 31. A belt 55 is provided on the surfaces of the first pulley 53 and the second pulley 54. A protective cover 56 is fixedly provided on the right side of the mounting frame 1.

Please refer to Figures 1, 8 and 9: when the rotating roller 31 is rotating, it will drive the second pulley 54 to rotate. The rotation of the second pulley 54 drives the first pulley 53 to rotate through the belt 55. The rotation of the first pulley 53 further drives the fertilization roller 52 to rotate, so that the fertilizer falls from the fertilizer hopper 51 to the surface of the desertified soil, thereby fertilizing the desertified soil.

A sowing mechanism 6 is fixedly provided on one side opposite to the two mounting seats 27, and the sowing mechanism 6 includes a storage bucket 61 fixedly provided on one side opposite to the two mounting seats 27, a sowing roller 62 is rotatably connected to the inner side of the storage bucket 61, first sprockets 63 are fixedly provided at both ends of the sowing roller 62 and on both sides of the storage bucket 61, second sprockets 64 are fixedly provided on the surfaces of both sides of the pressing roller 29, and chains 65 are sleeved on the surfaces of the first sprockets 63 and the second sprockets 64;

Please refer to Figures 1, 10 and 11: When the mounting frame 1 drives the pressure roller 29 to move and rotate, the pressure roller 29 will drive the second sprockets 64 on both sides to rotate, and the second sprockets 64 on both sides will drive the two first sprockets 63 to rotate through the chain 65. The rotation of the two first sprockets 63 will drive the sowing roller 62 to rotate, so that the grass seeds are scattered on the surface of the desertified soil.

The surface of the fertilizer roller 52 is provided with a plurality of fertilizer grooves at equal intervals, the inner side of the top of the mounting frame 1 is provided with a fertilizer groove used in conjunction with the fertilizer roller 52, and the surface of the sowing roller 62 is provided with four sowing grooves at equal intervals;

In this embodiment, unlike the method of using a single chemical sand fixation to prevent wind erosion, when the device turns over the desertified soil through the soil turning mechanism 3, the first pulley 53, the second pulley 54 and the belt 55 are used to drive the fertilizer roller 52 to rotate through the rotation of the rotating roller 31, and the fertilizer is spread on the surface of the desertified soil in front of the soil turning knife group 32, thereby improving the fertility of the desertified soil, which is beneficial to the growth of crops and the survival rate of crops. At the same time, the rotation of the soil turning knife group 32 can turn the fertilizer spread on the surface of the desertified soil to the middle and lower layers of the desertified soil, thereby avoiding the loss of fertilizer due to rainwater;

When the sandy soil is compacted by the compacting roller 29, the first sprocket 63, the second sprocket 64 and the chain 65 drive the sowing roller 62 to rotate, thereby sowing the grass seeds on the front side of the compacting roller 29. When the grass seeds grow, the roots of the grass can unite the sandy soil, and the blades of the grass can reduce the erosion of the surface sandy soil caused by wind, thereby improving the effect of preventing and controlling wind erosion of the sandy soil. When the compacting roller 29 compacts the sandy soil, the grass seeds can be pressed into the sandy soil, thereby improving the contact effect between the grass seeds and the sandy soil, allowing the grass seeds to absorb sufficient nutrients and water, thereby improving the survival rate of the grass seeds. By combining chemical sand fixation with plant sand fixation, the effect of preventing and controlling wind erosion of the sandy soil can be greatly improved.

Please refer to Figures 1 to 14 again, the working principle of the pretreatment device for preventing and controlling wind erosion of desertified soil provided by the present invention is as follows:

Step S1, first connect the device to the agricultural machine through the traction frame 9, and move the device through the agricultural machine. Before the device moves, first rotate the two rotating handles 23 and use the two threaded rods 24 to drive the two sliding frames 25 to slide downward, and adjust the height position of the scraping frame 26 through the movement of the two sliding frames 25, and then start the driving motor 33, the first water pump 43 and the second water pump 73 respectively, and drive the rotating roller 31 and the soil turning knife group 32 to rotate through the rotation of the driving motor 33, and use the soil turning knife group 32 to turn the sandy soil. The rotating roller 31 will drive the second pulley 54 to rotate during the rotation process, and the second pulley 54 will drive the first pulley 53 to rotate through the belt 55, and drive the fertilizer roller 52 to rotate through the first pulley 53, so that the fertilizer is sprinkled on the front side of the soil turning knife group 32, and the soil turning knife group 32 turns the fertilizer into the sandy soil;

Step S2, after starting the first water pump 43, the first water pump 43 transports the chemical repair liquid in the first storage box 41 to the inside of the spray pipe 46 through the pumping pipe and the spray hose 44, and then sprays the chemical repair liquid to the surface of the sandy soil in front of the soil turning knife group 32 through the spray head 47 at the bottom, and the soil turning knife group 32 turns the surface soil sprayed with the chemical repair liquid into the middle and lower layers of the sandy soil;

Step S3, when the agricultural machine is driven by the traction frame 9 to move, the scraping frame 26 can be set to level the desertified soil after turning over, and the compacting roller 29 can compact the leveled desertified soil. When compacting the desertified soil, the compacting roller 29 rotates on the ground, and the rotation of the compacting roller 29 drives the two second sprockets 64 to rotate. The two second sprockets 64 drive the two first sprockets 63 to rotate through the chain 65. The two first sprockets 63 drive the sowing roller 62 to rotate, and the grass seeds in the storage bucket 61 are sprinkled on the surface of the desertified soil in front of the compacting roller 29 through the sowing roller 62, and the grass seeds are pressed into the interior of the desertified soil through the compacting roller 29, so as to increase the contact area between the grass seeds and the desertified soil;

Step S4, when adjusting the height position of the scraping frame 26 downward, the scraping frame 26 will drive the two first rotating seats 81 to move downward, so that the bottoms of the two connecting rods 82 move downward, and the tops of the two connecting rods 82 move to both sides, and drive the two sliders 84 and the two groups of atomizing nozzles 75 to move to the separated side through the atomizing bracket 85, so as to adjust the spraying range of the two groups of atomizing nozzles 75, and by starting the second water pump 73, the second water pump 73 pumps the chemical repair liquid in the second storage box 71 to the atomizing nozzle 75 through the suction pipe and the atomizing hose 74, and the atomizing nozzle 75 sprays the chemical repair liquid onto the surface of the sandy soil after being compacted by the compacting roller 29, so as to repair and fix the surface layer of the sandy soil.
