Description

Technical Field

[0001] The invention belongs to the technical field of water and soil improvement, and in particular relates to a water and soil improvement system in coastal areas. Background Art

[0002] The salt content of groundwater in coastal areas is high, soil salinization is serious, and the degree of soil maturity is low. Improving the water and soil environment in coastal areas is an important task to promote the development of agricultural production in the region. Soil and water improvement refers to the use of a series of technical measures to achieve the effects of regulating groundwater levels, improving soil moisture conditions, improving soil conditions, and preventing and controlling soil erosion. As the salt content in coastal areas changes with seawater, groundwater rises along capillaries into the shallow surface soil, increasing the chloride ion content in the soil, deteriorating the soil structure, deteriorating the physical and chemical properties, and reducing the ecological fertility. Therefore, soil and water improvement in coastal areas is the improvement of saline-alkali land. However, the existing soil and water improvement systems in coastal areas often still have the following problems:

[0003] 1. When improving saline-alkali land in coastal areas, soil conditioners are often sprayed on the soil surface to change and balance the saline-alkali components contained in the saline-alkali soil. However, since the saline-alkali components of saline-alkali land are often higher in deeper areas, it is difficult to change and balance the saline-alkali components in deeper areas by spraying them on the soil surface, resulting in poor soil improvement effects.

[0004] 2. When spraying soil conditioners in the soil and water improvement system, the soil is often not tilled, which makes it impossible to cut off the transport of salt from soil capillary water to the surface, causing salt return and reducing the efficiency of soil and water improvement in saline-alkali land.

[0005] 3. Biological improvement uses biological measures such as microbial fertilizer to improve saline-alkali land, improving its intrinsic physical and chemical properties from the soil mechanism, but the desalination rate is relatively slow. Summary of the invention

[0006] The purpose of the present invention is to provide a water and soil improvement system for coastal areas in order to solve the problems mentioned in the above background technology, such as the inability to neutralize the saline-alkali components in the deep soil, the inability to perform tillage, and the slow desalination rate.

DETAILED DESCRIPTION

[0026] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0027] like Figure 1-5 As shown, a water and soil improvement system for coastal areas includes a vehicle body 1, a first rotating rod 2 is rotatably connected inside the vehicle body 1, an empty slot 4 is provided inside the vehicle body 1, a movable plate 5 is slidably connected in the empty slot 4, three second rotating rods 3 are rotatably connected to the movable plate 5, the three second rotating rods 3 are transmission-connected to the first rotating rod 2 through a transmission mechanism 6, the transmission mechanism 6 includes a first gear 17, a tooth column 19, three sprocket wheels 21 and a chain 22, the first rotating rod 2 is fixedly connected to the first rotating rod 2 with the first gear 17, one of the three second rotating rods 3 close to the first rotating rod 2 is fixedly connected to the tooth column 19, the first gear 17 is meshed with the tooth column 19, the three second rotating rods 3 are fixedly connected to the sprocket wheels 21 at positions below the tooth column 19, and the three sprocket wheels 21 are all sleeved with chains 22.

[0028] It is worth mentioning that when the first rotating rod 2 rotates, it will drive the first gear 17 to rotate. Since the first gear 17 is meshed with the tooth column 19, it will drive the second rotating rod 3 close to the first rotating rod 2 to rotate, and drive the other two second rotating rods 3 to rotate through the three sprockets 21 and the chain 22. The second rotating rod 3 can rotate while penetrating into the soil, thereby facilitating the second rotating rod 3 to drill into the soil, preventing the second rotating rod 3 from being unable to drill into the soil due to the soil being too hard when drilling into the soil, and ensuring the change and balance of the saline-alkali components deep in the soil. At the same time, since the radius of the first gear 17 is twice the radius of the tooth column 19, the rotation speed of the three second rotating rods 3 is faster, making it easier for the three second rotating rods 3 to drill into the soil.

[0029] A displacement mechanism 7 is provided at the bottom of the first rotating rod 2, and the three second rotating rods 3 are controlled by the first rotating rod 2 through the displacement mechanism 7. The displacement mechanism 7 includes a threaded rod 23, a threaded sleeve 24, a limit plate 25, and a limit groove 26. The threaded rod 23 is fixedly connected to the bottom of the first rotating rod 2. The threaded sleeve 24 is threadedly matched on the threaded rod 23. The limit plate 25 is fixedly connected to the threaded sleeve 24. The limit plate 25 extends into the empty slot 4 through the limit groove 26 and is fixedly connected to the moving plate 5. It should be noted that when the first rotating rod 2 rotates, the threaded rod 23 will be driven to rotate. The rod 23 rotates to move the threaded sleeve 24 downward, and drives the movable plate 5 to move downward through the limit plate 25. Since the three second rotating rods 3 are fixedly connected with sliders 27, the side walls of the rotating connection between the movable plate 5 and the three second rotating rods 3 are provided with slide grooves 28. The three sliders 27 are slidably connected to the inner walls of the three slide grooves 28 respectively. Therefore, when the movable plate 5 moves downward, it will drive the three second rotating rods 3 to move downward and drill into the deep soil, so that the soil conditioner can change and balance the saline-alkali components deeper in the soil, and the soil improvement effect is better.

[0030] A box body 10 is provided on the top of the vehicle body 1. The box body 10 controls the three second rotating rods 3 to discharge water through a water-passing mechanism 8. The water-passing mechanism 8 includes three water-passing pipes 29, two sliding sleeves 30, three drilling tools 31 and a plurality of through holes 32. The two upper parts of the three second rotating rods 3 away from the first rotating rod 2 are fixedly connected with the sliding sleeves 30. The two sliding sleeves 30 and the gear column 19 are slidably connected with the water-passing pipes 29. The top of each water-passing pipe 29 is fixedly connected to the bottom of the box body 10. The three second rotating rods 3 all adopt a hollow structure, and a plurality of through holes 32 are opened at the bottom. The bottoms of the three second rotating rods 3 are fixedly connected with the drilling tools 31.

[0031] It should be noted that when the three second rotating rods 3 are rotated and displaced downward, the gear column 19 and the two sliding sleeves 30 will be driven to displace on the three water pipes 29 respectively, ensuring that the three water pipes 29 are always connected to the gear column 19 and the two sliding sleeves 30, so that the soil conditioner in the box body 10 enters the gear column 19 and the two sliding sleeves 30 through the three water pipes 29 respectively, and flows into the interior of the three second rotating rods 3. Since the three second rotating rods 3 adopt a hollow structure, the soil conditioner will flow under the three second rotating rods 3 and penetrate into the deep soil through a number of through holes 32 to balance the saline-alkali components of the deep soil. The drilling tools 31 at the bottom of the three second rotating rods 3 can make it easier for the second rotating rods 3 to drill into the soil.

[0032] Two fixed rods 11 are fixedly connected to both sides of the bottom of the vehicle body 1, and the two fixed rods 11 on the same side are rotatably connected to the first rotating shaft 12, and wheels 14 are rotatably connected to both sides of the two first rotating shafts 12. A soil turning mechanism 9 is provided on one of the two first rotating shafts 12, and the soil turning mechanism 9 includes two second gears 18, a rack 20, a second rotating shaft 13, a spring 33, a spring groove 34, a shovel plate 35 and a fixed plate 36. A fixed plate 36 is fixedly connected to the bottom of the vehicle body 1, and the second rotating shaft 13 is rotatably connected to the fixed plate 36. The second gear 18 is fixedly connected to the first rotating shaft 12 and the second rotating shaft 13. A spring groove 34 is opened at the bottom of the vehicle body 1, and a rack 20 is provided at the bottom of the vehicle body 1. The rack 20 is elastically connected to the upper wall of the spring groove 34 through a spring 33. The two second gears 18 are respectively meshed with both sides of the rack 20, and a shovel plate 35 is fixedly connected to the second rotating shaft 13.

[0033] It is worth mentioning that when the vehicle body 1 rotates through the wheels 14, the two first rotating shafts 12 will be driven to rotate. Since the second rotating shaft 13 and the first rotating shaft 12 close to the second rotating shaft 13 are fixedly connected with the second gear 18, and the two second gears 18 are respectively engaged with the two sides of the rack 20, when the vehicle body 1 moves forward, the first rotating shaft 12 and the second rotating shaft 13 will be driven to move in the opposite direction, so that the shovel plate 35 on the second rotating shaft 13 will swing to shovel the soil. Since the two second gears 18 are both quarter gears, after shoveling the soil, The two second gears 18 are no longer meshed with the rack 20. The rack 20 returns to the initial position due to the elastic force of the spring 33. The friction between the ground and the shovel plate 35 causes the shovel plate 35 to swing in the opposite direction, and the second gear 18 on the second rotating shaft 13 returns to the initial position. When the first rotating shaft 12 rotates to the same position, the two second gears 18 rotate again to achieve tillage of the soil, which not only makes it convenient for the second rotating rod 3 to drill into the soil to inject soil conditioner, but also loosens the soil, cuts off the soil capillary water to transport salt to the surface, prevents salt return, and increases the efficiency of soil and water improvement in saline-alkali land.

[0034] A finishing plate 37 is fixedly connected to the side of the bottom of the vehicle body 1 away from the soil-turning mechanism 9, which can flatten and tidy up the soil after plowing. A first motor 15 and a second motor 16 are fixedly connected to the top of the vehicle body 1. The output shaft of the first motor 15 is fixedly connected to the first rotating rod 2. The model of the first motor is 80DK-M07725. The second motor 16 controls the opening and closing of the four wheels 14. The model of the second motor is YCCL160L-8.

[0035] The present invention can be explained by the following operation mode:

[0036] When in use, the second motor 16 is turned on to start the vehicle body 1 to move. During the movement, the soil turning mechanism 9 is driven to start working, so that the shovel plate 35 shovels the soil back and forth to achieve soil turning, which not only prevents the occurrence of salt return, but also facilitates the three second rotating rods 3 to drill into the soil.

[0037] When it is displaced to a suitable position, the first motor 15 is turned on, and the soil conditioner is injected into the box body 10. The first motor 15 drives the first rotating rod 2 to rotate, and the displacement mechanism 7 drives the three second rotating rods 3 to move downward. While the second rotating rods 3 are displaced, the transmission mechanism 6 drives the three second rotating rods 3 to rotate, so that the three second rotating rods 3 can drill into the deep soil. The soil conditioner in the box body 10 penetrates into the deep soil through the water passing mechanism 8 as the second rotating rods 3 drill into the deep soil, so as to change and balance the saline-alkali components in the deep soil.

[0038] After the work is completed, the first motor 15 is turned on again to make the first rotating rod 2 rotate in the opposite direction to return to the initial position, and the second motor 16 is turned on to move the vehicle body 1 to the next work location.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
