Description

Technical Field

[0001] This utility model belongs to the field of aeration and drainage technology for saline-alkali land, specifically the aeration and drainage pipe for crop roots in saline-alkali land. Background Technology

[0002] Saline-alkali land refers to a special type of land where excessive accumulation of soluble salts in the soil leads to deterioration of soil physical and chemical properties, decline in fertility, and consequently affects the normal growth of plants.

[0003] Planting crops in saline-alkali land is quite difficult. First, the surface soil structure is relatively compacted and has poor aeration. Second, the high salt content in the soil increases the osmotic pressure of the soil solution, making it relatively difficult for plant roots to absorb water. Third, due to the high salt content, the number of microorganisms decreases, the decomposition of organic matter is slow, and the soil fertility is insufficient. Most of the above reasons are caused by the high salt content in the shallow soil. Therefore, how to reduce the salt content in the shallow soil of saline-alkali land is a key factor in reducing the difficulty of crop planting.

[0004] Therefore, this utility model provides a ventilation and drainage pipe for the roots of crops in saline-alkali land. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The saline-alkali land crop root aeration and drainage pipe of this utility model includes a horizontal pipe, a plurality of longitudinal pipes fixed to the top of the horizontal pipe, a discharge pipe fixed to the bottom of the horizontal pipe, a plurality of seepage holes in the middle of the longitudinal pipe, a mud-blocking cloth installed inside the longitudinal pipe, a support component installed inside the mud-blocking cloth, and a protective mechanism installed at the top of the horizontal pipe. Through the above structure, some of the salt in the shallow soil is transferred to the lower soil, and the salinity of the shallow soil is alleviated to a certain extent, thereby reducing the impact on plant roots. Moreover, the air in the longitudinal pipe can also be directly exchanged with the gas in the shallow soil through the multiple seepage holes, increasing the aeration of the crop roots.

[0007] Preferably, the protective mechanism includes a connecting pipe, which is detachably installed on the top of the longitudinal pipe. A bracket is fixed inside the connecting pipe, and a cover plate is installed on the top of the bracket. With the above structure, the occurrence of blockage of the longitudinal and transverse pipes caused by large substances entering the longitudinal pipe can be reduced. Moreover, the connecting pipe can be removed to take out the mud-blocking cloth for maintenance and replacement, which has little impact on the convenience of mud-blocking cloth maintenance.

[0008] Preferably, the support assembly includes a pair of connecting rings, with a connecting plate fixed between the pair of connecting rings. The two ends of the mud-blocking cloth are respectively connected to the pair of connecting rings. Through the above structure, the ease of disassembly and assembly of the mud-blocking cloth is improved, and the mud-blocking cloth entering the longitudinal pipe is less likely to collapse, thus preventing soil infiltration due to the inability to cover some seepage holes.

[0009] Preferably, a lifting rod is fixed to the middle of the connecting plate, and a positioning groove is provided on the inner side wall of the longitudinal tube. With the above structure, after installation, the connecting plate is staggered from multiple seepage holes, reducing the possibility of the connecting plate blocking some seepage holes and causing a decrease in drainage effect.

[0010] Preferably, an additional pipe is detachably installed on the top of one of the longitudinal pipes, and a corresponding protective mechanism is installed on the additional pipe. Through the above structure, the flow of gas in the horizontal and longitudinal pipes is increased, thereby improving the air permeability of plant roots by exchanging air in the pipes with air in the soil through the seepage holes.

[0011] Preferably, the bracket is threaded with an adjusting bolt in the middle, and the cover plate is rotatably connected to the top of the adjusting bolt. With the above structure, the distance between the connecting pipe and the cover plate can be adjusted, improving the applicability of the device.

[0012] Preferably, the edge of the cover plate is fixed with multiple blocking strips, and the bottom ends of the multiple blocking strips are fixed to the middle of the connecting pipe. Through the above structure, the blocking strips can block some of the material, thereby improving the blocking effect of the protective mechanism on debris and further reducing the occurrence of debris falling into the horizontal and vertical pipes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The saline-alkali land crop root aeration and drainage pipe of this utility model, through the setting of horizontal pipes, vertical pipes, discharge pipes, seepage holes and mud-blocking cloth, allows some of the salt in the shallow soil to be transferred to the lower soil layer, which alleviates the salinity of the shallow soil to a certain extent, thereby reducing the impact on plant roots. Moreover, the air in the vertical pipe can also be directly exchanged with the gas in the shallow soil through multiple seepage holes, increasing the aeration of the crop roots.

[0015] 2. The root aeration and drainage pipe for crops in saline-alkali land described in this utility model, through the setting of connecting pipe, support, and cover plate, can reduce the occurrence of blockage of the longitudinal and transverse pipes caused by large substances entering the longitudinal pipe. Moreover, the connecting pipe can be removed to take out the mud-blocking cloth for maintenance and replacement, which has little impact on the convenience of mud-blocking cloth maintenance.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the figure, the root aeration and drainage pipe for crops in saline-alkali land according to this utility model includes a horizontal pipe 1, a plurality of longitudinal pipes 12 fixed to the top of the horizontal pipe 1, a discharge pipe 13 fixed to the bottom of the horizontal pipe 1, a plurality of seepage holes 14 opened in the middle of the longitudinal pipes 12, a mud-blocking cloth 15 installed inside the longitudinal pipes 12, a support component installed inside the mud-blocking cloth 15, and a protective mechanism installed at the top of the horizontal pipe 1. During operation, the horizontal pipe 1 is buried in the saline-alkali land, so that the top of the longitudinal pipes 12 extends out of the soil and is higher than the ground level by a certain height. Some of the saline water in the shallow soil will seep into the longitudinal pipes through the seepage holes 14. Inside pipe 12, the mud-blocking cloth 15 will block the soil. After the saline water seeps into the longitudinal pipe 12 through the seepage hole 14, it will flow into the horizontal pipe 1 and then into the discharge pipe 13 along the inclined horizontal pipe 1. Finally, it will flow into the deeper soil layer through the discharge pipe 13 and seep in. Since some of the salt in the shallow soil is transferred to the lower soil layer through the above steps, the salinity of the shallow soil is alleviated to a certain extent, thereby reducing the impact on plant roots. Moreover, the air in the longitudinal pipe 12 can also directly exchange with the gas in the shallow soil through multiple seepage holes 14, increasing the permeability of the crop roots.

[0025] like Figures 1 to 5As shown, the protective mechanism includes a connecting pipe 2, which is detachably installed on the top of the longitudinal pipe 12. A bracket 21 is fixed inside the connecting pipe 2, and a cover plate 22 is installed on the top of the bracket 21. The cover plate 22 can block some larger soil clods, plant leaves and other debris, making it difficult for debris to enter the longitudinal pipe 12 and the transverse pipe 1, thus reducing the occurrence of blockage. Through the above structure, the occurrence of blockage caused by larger materials entering the longitudinal pipe 12 and the transverse pipe 1 can be reduced. Moreover, the connecting pipe 2 can be removed to take out the mud-blocking cloth 15 for maintenance and replacement, which has little impact on the convenience of maintenance of the mud-blocking cloth 15.

[0026] like Figures 1 to 4 As shown, the support assembly includes a pair of connecting rings 3, with a connecting plate 31 fixed between them. The two ends of the mud-blocking cloth 15 are connected to the pair of connecting rings 3 respectively. When the mud-blocking cloth 15 needs to be installed, the two ends of the mud-blocking cloth 15 are first tied to the connecting rings 3 with steel wires, etc. Then, the connecting rings 3, connecting plates 31, and mud-blocking cloth 15 are inserted into the longitudinal pipe 12 to complete the installation of the mud-blocking cloth 15. After the mud-blocking cloth 15 enters the longitudinal pipe 12, it is difficult to collapse due to the restriction of the connecting rings 3 and connecting plates 31, and it can maintain the state of covering multiple seepage holes 14. When the mud-blocking cloth 15 needs to be replaced, the connecting rings 3 can be pulled directly to remove the connecting rings 3, connecting plates 31, and mud-blocking cloth 15. Through the above structure, the ease of installation and removal of the mud-blocking cloth 15 is improved, and the mud-blocking cloth 15 entering the longitudinal pipe 12 is difficult to collapse, which would prevent the mud-blocking cloth 15 from failing to cover some of the seepage holes 14 and causing soil infiltration.

[0027] like Figures 1 to 4 As shown, a lifting rod 4 is fixedly connected to the middle of the connecting plate 31, and a positioning groove 41 is provided on the inner side wall of the longitudinal tube 12. When the connecting ring 3 and the connecting plate 31 are installed into the longitudinal tube 12, the angle of the lifting rod 4 is adjusted so that the end of the lifting rod 4 points to the positioning groove 41. Thus, after the installation is completed, the connecting plate 31 is staggered from the multiple seepage holes 14, reducing the possibility that the connecting plate 31 will block some of the seepage holes 14, resulting in a decrease in the drainage effect.

[0028] like Figures 1 to 2As shown, a mounting pipe 5 is detachably installed on the top of a longitudinal pipe 12, and a corresponding protective mechanism is installed on the mounting pipe 5. In order to increase the airflow in the horizontal pipe 1 and the longitudinal pipe 12, a mounting pipe 5 can be installed on a longitudinal pipe 12, so that the top of the mounting pipe 5 is much higher than the crop growth height. The wind at the position higher than the crop growth height is less affected by the crop and the wind force is greater. According to Bernoulli's principle, the higher the flow velocity, the lower the pressure. Therefore, when the wind blows over the top of the mounting pipe 5, the air pressure at the top of the mounting pipe 5 is relatively reduced. The air in the longitudinal pipe 12 and the horizontal pipe 1 will flow towards the top of the mounting pipe 5 under the action of the pressure difference, thereby causing the air at the top of other longitudinal pipes 12 to rush in, increasing the airflow in the horizontal pipe 1 and the longitudinal pipe 12, and thus improving the effect of air exchange between the air in the pipe and the air in the soil through the seepage hole 14 on improving the aeration of the plant roots.

[0029] like Figure 5 As shown, the bracket 21 is threaded with an adjusting bolt 6 in the middle, and the cover plate 22 is rotatably connected to the top of the adjusting bolt 6. After a protective mechanism is installed on the mounting pipe 5, the adjusting bolt 6 can be rotated to adjust the distance between the cover plate 22 and the connecting pipe 2 to make the gap larger so that the wind can pass through. Other protective mechanisms can also adjust the distance between the cover plate 22 and the connecting pipe 2 by rotating the adjusting bolt 6 as needed. Through the above structure, the distance between the connecting pipe 2 and the cover plate 22 can be adjusted to improve the applicability of the device.

[0030] like Figure 5 As shown, multiple blocking strips 7 are fixed to the edge of the cover plate 22, and the bottom ends of the multiple blocking strips 7 are fixed to the middle of the connecting pipe 2. Through the above structure, the blocking strips 7 can block some of the material, which can improve the blocking effect of the protective mechanism on the debris and further reduce the occurrence of debris falling into the horizontal pipe 1 and the vertical pipe 12.

[0031] During operation, the horizontal pipe 1 is buried in the saline-alkali soil, with the top of the vertical pipe 12 extending from the soil and above ground level. Some saline water in the shallow soil seeps into the vertical pipe 12 through the seepage holes 14. The mud-blocking cloth 15 prevents soil leakage. After seeping into the vertical pipe 12 through the seepage holes 14, the saline water flows into the horizontal pipe 1 and then along the inclined horizontal pipe 1 into the discharge pipe 13. Finally, it flows into the deeper soil layers through the discharge pipe 13 and seeps in. Because some of the salt in the shallow soil is transferred to the lower soil layers through the above steps, the salinity of the shallow soil is somewhat alleviated, thereby reducing the impact on plant roots. Furthermore, the air inside the longitudinal pipe 12 can directly exchange with the gas in the shallow soil through multiple seepage holes 14. The cover plate 22 can block some larger soil clods, fallen leaves, and other debris, making it difficult for debris to enter the longitudinal pipe 12 and the horizontal pipe 1, reducing the occurrence of blockages. When it is necessary to install the mud-blocking cloth 15, first tie both ends of the mud-blocking cloth 15 to the connecting ring 3 with steel wire, etc., and then insert the connecting ring 3, connecting plate 31, and mud-blocking cloth 15 into the longitudinal pipe 12 to complete the installation of the mud-blocking cloth 15. After the mud-blocking cloth 15 is inserted into the longitudinal pipe 12, it is difficult to loosen due to the restriction of the connecting ring 3 and connecting plate 31, thus maintaining the multiple seepage holes. In the state of 14-covered, when it is necessary to replace the mud-blocking cloth 15, the connecting ring 3, connecting plate 31, and mud-blocking cloth 15 can be removed by directly pulling the connecting ring 3. When installing the connecting ring 3 and connecting plate 31 into the longitudinal pipe 12, the angle of the lifting rod 4 is adjusted so that the end of the lifting rod 4 points to the positioning groove 41. After the installation is completed, the connecting plate 31 is staggered from the multiple seepage holes 14. In order to increase the air flow in the horizontal pipe 1 and the longitudinal pipe 12, an auxiliary pipe 5 can be installed on one of the longitudinal pipes 12, so that the top of the auxiliary pipe 5 is much higher than the crop growth height. The wind at the position higher than the crop growth height is less affected by the crop and the wind force is lower. According to Bernoulli's principle, the higher the flow velocity, the lower the pressure. Therefore, when the wind blows over the top of the mounting pipe 5, the air pressure at the top of the mounting pipe 5 is relatively reduced. The air in the longitudinal pipe 12 and the horizontal pipe 1 will flow towards the top of the mounting pipe 5 under the action of the pressure difference, thereby causing the air at the top of other longitudinal pipes 12 to rush in, increasing the flow of gas in the horizontal pipe 1 and the longitudinal pipe 12. After a protective mechanism is installed on the mounting pipe 5, the distance between the cover plate 22 and the connecting pipe 2 can be adjusted by rotating the adjusting bolt 6 to make the interval larger so that the wind can pass through. Other protective mechanisms can also be adjusted by rotating the adjusting bolt 6 to adjust the distance between the cover plate 22 and the connecting pipe 2 as needed.
