Description

Technical Field

[0001] The invention relates to the technical field of underground irrigation, and in particular to an underground water-saving irrigation device and method for mountain apples. Background Art

[0002] Fruit trees refer to edible fruit trees, and are a general term for perennial plants and their rootstocks that can provide edible fruit and seeds. In farms, irrigation of fruit trees is very important. It can provide the right amount of water for the fruit trees to meet the needs of their growth, and ultimately achieve the goal of increasing yields, improving quality, and maintaining the health of the fruit trees. Appropriate irrigation management needs to be adjusted and implemented in combination with the characteristics of the fruit trees, the growth environment, and local climatic conditions. Underground drip irrigation is an effective way to irrigate fruit trees. It irrigates near the roots of the trees by burying pipes, supplying water directly to the root system, which reduces water evaporation and waste and improves irrigation efficiency.

[0003] Current irrigation cannot adjust the amount of water output according to the actual amount of water required by the seedlings, resulting in poor irrigation effect due to too little water output, and large water output that impacts the soil and affects the water and soil. Large water output will affect plant growth and cause water waste. At the same time, the irrigation water pipe passes through a filter to prevent soil from entering the pipe and causing blockage. After the filter has been used for a period of time, the filter will become corroded and blocked, and thus needs to be replaced. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an underground water-saving irrigation device and method for mountain apples, comprising a water pipe, an extension pipe is fixedly connected to the outside of the water pipe, and a connecting pipe is provided at one end of the extension pipe away from the connecting pipe; A limiting component, the limiting component is fixedly connected to an end of the connecting tube away from the extension tube; An irrigation component, the irrigation component is fixedly installed at the bottom of the limiting component; Among them, the irrigation component includes a fixed block, the fixed block is fixedly connected to the limiting component, a water inlet hole is opened in the middle of the interior of the fixed block, the water inlet hole is connected to the connecting pipe through the limiting component, there are three fixed blocks, the three fixed blocks are evenly distributed, and a pipe is fixedly connected to the outside of the fixed block. After the irrigation component is installed, the water pipe is connected to the water source to pass water, and the water enters the inside of the connecting pipe through the extension pipe, and then the water enters the water inlet hole of the fixed block through the limiting component, so that the water enters the inside of the pipe. Under the flow of water, the spring plate is deformed by force, so that the spring plate drives the middle plate to rotate inside the pipe, so that the ring rotates on the outside of the pipe, so that the through hole coincides with the water outlet. At this time, water is irrigated through the water outlet. By setting the ring, the obstruction of the water outlet by the soil when the irrigation component is buried is avoided, which affects the circulation of water. By setting the pipe as a spiral setting, the special shape of the spiral pipe will cause the water flow to form a spiral flow path in the pipe. This flow mode can effectively reduce the water flow speed, which is It helps to reduce the pressure impact of water flow on the inner wall of the pipe and reduce the risk of pipe wear and rupture. The slow water flow can form a more stable moisture in the soil, ensuring that the plant roots can fully absorb water. At the same time, when the pipe is subjected to soil pressure from above or other external pressure, the spiral shape can effectively disperse the pressure. The pipe is spirally set, and a water outlet is opened on the outside of the pipe. The outside of the pipe is rotatably connected with a ring, which is located on the side close to the water outlet. The ring is sleeved on the outside of the pipe, and a through hole is opened on the outside of the ring. Since the shape and distribution of the plant root system are irregular, the spiral pipe can better conform to this irregularity. The spiral pipe can be laid according to the direction of the root system, so that the irrigation water is directly transported to the part where the root system needs it most, reducing the waste of water in non-root areas and improving the utilization efficiency of irrigation water. The inner wall of the ring close to the water outlet is fixedly connected with an intermediate plate, and the side of the intermediate plate close to the ring is fixedly connected with a spring plate, and the spring plate is fixedly connected to the inner wall of the pipe.

[0005] Preferably, a reinforcing plate is fixedly connected to the outside of the pipe, and there are multiple reinforcing plates, which are evenly distributed on two adjacent fixed blocks. The reinforcing plates and the circular rings are alternately arranged, and a square groove is opened on the outside of the fixed block. A partition is fixedly connected to the end of the circular ring close to the through hole. The reinforcing plate is arranged on the outside of the pipe, and the reinforcing plate can be used as a supporting structure to maintain the horizontality and verticality of the pipe. The reinforcing plate can limit the displacement and shaking of the pipe, prevent deformation and disconnection of the pipe due to uneven settlement of soil, and ensure the long-term stability of the irrigation system. At the same time, the reinforcing plate can enhance the ability of the pipe to resist impact, reduce the risk of damage to the pipe caused by disasters, and reduce irrigation interruption and waste of water resources due to pipe damage. There are two partitions, which are symmetrically arranged with the through hole as the center, and a base is fixedly connected to the bottom of the fixed block.

[0006] Preferably, the extension tube is threadedly connected to the connecting tube, the inner wall of the extension tube is fixedly connected to the limiting ring, the inner wall of the limiting ring is set to be inclined, the inner wall of the connecting tube is fixedly connected to the limiting plate, the limiting plate is set as an L-shaped plate, the contact surface between the limiting plate and the limiting ring is set to be inclined, and after the connecting tube and the extension tube are installed, the contact surface between the limiting plate and the limiting ring is relatively squeezed, and a sealing layer is formed by setting the limiting plate, the limiting ring and the protrusion to prevent water leakage at the connection between the extension tube and the connecting tube, resulting in the surrounding soil being in an over-wet state, the leaked water will wash away the soil particles, reduce the soil fertility, and may also cause the plant roots to be exposed, affecting the growth of plants, and at the same time, excessive water accumulation in local areas will cause waterlogging, causing the plant roots to be deprived of oxygen, and then cause the root system to rot, and the sealed connection can avoid this situation from happening, ensure that irrigation water enters the soil according to the designed path and amount, maintain normal humidity and air permeability of the soil, and create a good environment for plant growth, the side of the limiting plate close to the limiting ring is set to an inclined surface, and the limiting plate is fixedly connected to the inner wall of the limiting ring close to the limiting ring with a protrusion.

[0007] Preferably, the limiting assembly includes a connecting tube, a threaded groove is provided on the outer side of the connecting tube near the connecting tube, the connecting tube is threadedly connected to the end of the connecting tube away from the extension tube, a trapezoidal tube is fixedly connected at the middle of the bottom of the connecting tube, the bottom edge of the connecting tube is fixedly connected to the fixed block, the water inlet is communicated with the connecting tube, and a circular hole is provided on the outer side of the trapezoidal tube. In the initial state, the circular plate is located on the upper surface of the trapezoidal block, the water pipe is connected to the water source for water to pass through, and the water enters the interior of the connecting tube through the extension tube and the connecting tube. At this time, the water inside the connecting tube enters the interior of the fixed block through the gap between the inclined groove and the notch on the cylinder to irrigate the plant roots. At the same time, the water inside the soil will penetrate into the interior of the trapezoidal block and the trapezoidal tube through the circular hole under saturation. As the amount of water increases, the ball moves upward inside the limiting hole due to buoyancy, and the ball drives the circular plate to move through the round rod, so that the notch and the cylinder slide relatively. At this time, the notch is blocked by the cylinder, and the equipment stops irrigating, which can prevent excessive water from seeping in. Penetrating deep into the soil and unable to be absorbed by the plant roots can ensure that the irrigation water is fully utilized in the root activity layer, reducing the waste of water resources. At the same time, excessive irrigation leads to excessive soil infiltration, which will fill the soil pores with water and cause root hypoxia. Irrigation should be stopped in time to maintain proper aeration in the soil, ensure normal breathing of the plant roots, better absorb nutrients, reduce diseases such as root rot caused by hypoxia, and promote healthy plant growth. There are multiple circular holes, and the multiple circular holes are evenly distributed in the trapezoidal cylinder. The interior of the trapezoidal cylinder is fixedly connected with a trapezoidal block, and the trapezoidal block is fixedly connected to the connecting cylinder through a connecting rod. A limited hole is opened in the middle of the trapezoidal block, and a spherical ball is slidably connected to the inner wall of the limited hole. The top of the sphere is fixedly connected with a round rod, and the end of the round rod away from the sphere is fixedly connected with a round plate. The outer side of the round plate is slidably connected to the inner wall of the connecting cylinder, and a notch is opened at the top of the round plate. The top of the fixed block is fixedly connected with a cylinder near the notch, and an inclined groove is opened on the outer side of the cylinder.

Stop irrigation. The water inside the soil will penetrate into the trapezoidal blocks and trapezoidal cylinders through the circular holes when the soil is saturated. As the amount of water increases, the sphere is driven by buoyancy to move the circular plate through the circular rod. At this time, the notch is blocked by the cylinder and the equipment stops irrigating.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0017] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: an underground water-saving irrigation device and method for mountain apples, comprising a water pipe 1, an extension pipe 5 is fixedly connected to the outside of the water pipe 1, and a connecting pipe 2 is provided at one end of the extension pipe 5 away from the connecting pipe 2; A limiting component 3, the limiting component 3 is fixedly connected to an end of the connecting tube 2 away from the extension tube 5; An irrigation component 4, which is fixedly mounted on the bottom of the limiting component 3; Among them, the irrigation component 4 includes a fixed block 42, the fixed block 42 is fixedly connected to the limiting component 3, a water inlet hole 46 is opened in the middle of the fixed block 42, the water inlet hole 46 is connected to the connecting pipe 2 through the limiting component 3, there are three fixed blocks 42, the three fixed blocks 42 are evenly distributed, and the outer side of the fixed block 42 is fixedly connected with a pipe 44. After the irrigation component 4 is installed, the water pipe 1 is connected to the water source and water enters the inside of the connecting pipe 2 through the extension pipe 5, and then the water enters the inside of the water inlet hole 46 of the fixed block 42 through the limiting component 3, so that the water enters the inside of the pipe 44. Under the flow of water, the spring plate 48 is deformed by force, so that the spring plate 48 drives the middle plate 412 to rotate inside the pipe 44, so that the ring 49 rotates outside the pipe 44, so that the through hole 410 coincides with the water outlet 47. At this time, water is irrigated through the water outlet 47. By setting the ring 49, it is avoided that the soil blocks the water outlet 47 when the irrigation component 4 is buried, which affects the flow of water. By setting the pipe 44 as a spiral setting, the special shape of the spiral pipe 44 will cause the water flow to form a spiral flow path in the pipe. This flow mode can effectively reduce the water flow. Speed, which helps to reduce the pressure impact of water flow on the inner wall of pipe 44, reduce the risk of wear and rupture of pipe 44, slow water flow can form more stable moisture in the soil, ensure that plant roots can fully absorb water, and when pipe 44 is subjected to soil pressure from above or other external pressure, the spiral shape can effectively disperse the pressure. Pipe 44 is spirally set, and a water outlet 47 is opened on the outside of pipe 44. The outside of pipe 44 is rotatably connected with a ring 49, which is located on the side close to the water outlet 47 and is sleeved on the outside of pipe 44. A through hole 410 is provided on the outer side of the ring 49. Since the shape and distribution of the plant root system are irregular, the spiral pipe 44 can better conform to this irregularity. The spiral pipe 44 can be laid according to the direction of the root system, so that the irrigation water can be directly transported to the part where the root system needs it most, reducing the waste of water in non-root areas and improving the utilization efficiency of irrigation water. The inner wall of the ring 49 near the water outlet 47 is fixedly connected with an intermediate plate 412, and the side of the intermediate plate 412 near the ring 49 is fixedly connected with a spring plate 48, and the spring plate 48 is fixedly connected to the inner wall of the pipe 44.

[0018] A reinforcing plate 43 is fixedly connected to the outside of the pipe 44. There are multiple reinforcing plates 43, which are evenly distributed on two adjacent fixed blocks 42. The reinforcing plates 43 and the circular rings 49 are alternately arranged. A square groove 45 is opened on the outside of the fixed block 42. A partition 411 is fixedly connected to the end of the circular ring 49 near the through hole 410. The reinforcing plate 43 is arranged on the outside of the pipe 44. The reinforcing plate 43 can be used as a supporting structure to maintain the horizontality and verticality of the pipe 44. The reinforcing plate 43 can limit the displacement and shaking of the pipe 44, prevent the pipe 44 from being deformed or disconnected due to uneven settlement of soil, and ensure the long-term stability of the irrigation system. At the same time, the reinforcing plate 43 can enhance the ability of the pipe 44 to resist impact, reduce the risk of damage to the pipe 44 caused by disasters, and reduce irrigation interruption and water resource waste caused by damage to the pipe 44. There are two partitions 411, and the two partitions 411 are symmetrically arranged with the through hole 410 as the center. The bottom of the fixed block 42 is fixedly connected to the base 41.

[0019] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the extension tube 5 is threadedly connected to the connecting tube 2, the inner wall of the extension tube 5 is fixedly connected to the limiting ring 6, the inner wall of the limiting ring 6 is set to be inclined, the inner wall of the connecting tube 2 is fixedly connected to the limiting plate 7, the limiting plate 7 is set as an L-shaped plate, and the contact surface between the limiting plate 7 and the limiting ring 6 is set to be inclined. After the connecting tube 2 and the extension tube 5 are installed, the contact surface between the limiting plate 7 and the limiting ring 6 is relatively squeezed, and a sealing layer is formed by setting the limiting plate 7, the limiting ring 6 and the protrusion 8 to prevent water leakage at the connection between the extension tube 5 and the connecting tube 2, causing the surrounding soil to be in an over-wet state. In this state, the leaked water will wash away the soil particles, reduce the soil fertility, and may also cause the plant roots to be exposed, affecting the growth of plants. At the same time, excessive water accumulation in local areas will cause waterlogging, causing the plant roots to be lack of oxygen, and then lead to root rot. The sealed connection can avoid this situation and ensure that the irrigation water enters the soil according to the designed path and amount, maintains the normal humidity and air permeability of the soil, and creates a good environment for plant growth. The side of the limit plate 7 close to the limit ring 6 is set as an inclined surface, and the limit plate 7 is fixedly connected to the inner wall of the limit ring 6 with a protrusion 8.

[0020] The third embodiment is based on the first and second embodiments. Figures 8 to 10As shown, the limit assembly 3 includes a connecting tube 31, a thread groove 32 is provided on the outer side of the connecting tube 31 near the connecting pipe 2, the connecting tube 31 is threadedly connected to the end of the connecting pipe 2 away from the extension pipe 5, a trapezoidal tube 33 is fixedly connected to the middle of the bottom of the connecting tube 31, the bottom edge of the connecting tube 31 is fixedly connected to the fixing block 42, the water inlet hole 46 is connected to the connecting tube 31, and a circular hole 36 is provided on the outer side of the trapezoidal tube 33. In the initial state, the circular plate 39 is located on the upper surface of the trapezoidal block 34, the water pipe 1 is connected to the water source, and water enters the connecting tube 31 through the extension pipe 5 and the connecting pipe 2. At this time, the water in the connecting tube 31 enters the interior of the fixed block 42 through the gap between the inclined groove 312 and the notch 310 on the cylinder 311 to irrigate the plant roots. At the same time, the water in the soil will penetrate into the trapezoidal block 34 and the trapezoidal tube 33 through the circular hole 36 in a saturated state. As the water increases, the ball 37 moves upward inside the limiting hole 38 due to the buoyancy. The ball 37 drives the circular plate 39 to move through the round rod 35, so that the notch 310 and the cylinder 311 slide relative to each other. At this time, the notch 310 is blocked by the cylinder 311, and the equipment stops irrigating. Irrigation can prevent excessive water from penetrating into the deep soil layer and being unable to be absorbed by the plant roots. It can ensure that the irrigation water is fully utilized in the root activity layer, reducing the waste of water resources. At the same time, excessive irrigation leads to excessive soil infiltration, which will fill the soil pores with water and cause root hypoxia. Irrigation should be stopped in time to maintain proper aeration in the soil, ensure the normal breathing of the plant roots, better absorb nutrients, reduce diseases such as root rot caused by hypoxia, and promote healthy growth of plants. There are multiple circular holes 36, and the multiple circular holes 36 are evenly distributed on the trapezoidal tube 33.

The outer side of the round plate 39 is slidably connected to the inner wall of the connecting tube 31, and a notch 310 is provided on the top of the circular plate 39. A cylinder 311 is fixedly connected to the top of the fixed block 42 near the notch 310, and an inclined groove 312 is provided on the outer side of the cylinder 311.

[0021] A mountain apple underground water-saving irrigation method comprises the following steps: S1, fixed installation, burying the irrigation assembly 4 in the soil, so that the spiral pipe 44 is laid according to the direction of the root system, so that the irrigation water is directly delivered to the part of the root system that needs it most; S2, underground irrigation, water pipe 1 is connected to the water source, water enters the interior of pipe 44 through extension pipe 5 and connecting pipe 2, the spring plate 48 is deformed by force to drive the middle plate 412 to rotate, the through hole 410 coincides with the water outlet 47, and water is irrigated through the water outlet 47; S3, adjusting the flow rate, by adjusting the internal flow rate of the water pipe 1, so that the overlapping area of ​​the water outlet 47 and the through hole 410 changes accordingly, and an appropriate amount of water can be provided according to the actual needs of the seedlings to ensure the healthy growth of the seedlings; S4, stop irrigation. The water inside the soil will penetrate into the trapezoidal block 34 and the trapezoidal cylinder 33 through the circular hole 36 when it is saturated. As the amount of water increases, the ball 37 is driven by the buoyancy to move the circular plate 39 through the circular rod 35. At this time, the notch 310 is blocked by the cylinder 311, and the equipment stops irrigation.

[0022] When in use, after the irrigation component 4 is installed, the water pipe 1 is connected to the water source and water is passed through the water pipe 1. The water enters the interior of the connecting pipe 2 through the extension pipe 5, and then the water enters the water inlet hole 46 of the fixed block 42 through the limit component 3, so that the water enters the interior of the pipe 44. Under the flow of water, the spring plate 48 is deformed by force, so that the spring plate 48 drives the middle plate 412 to rotate inside the pipe 44, so that the ring 49 rotates on the outside of the pipe 44, so that the through hole 410 coincides with the water outlet 47. At this time, water is irrigated through the water outlet 47.

[0023] When the water inside the soil is in a saturated state, the water will penetrate into the trapezoidal block 34 and the trapezoidal cylinder 33 through the circular hole 36. As the amount of water increases, the ball 37 moves upward inside the limiting hole 38 due to the buoyancy. The ball 37 drives the circular plate 39 to move through the circular rod 35, causing the slot 310 and the cylinder 311 to slide relative to each other. At this time, the slot 310 is blocked by the cylinder 311, and the equipment stops irrigating.
