Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation, and in particular relates to an irrigation device for crop planting. Background Technology

[0002] Traditional agricultural irrigation methods have obvious drawbacks, resulting in serious waste and hindering the conservation and utilization of water resources. In order to achieve water conservation while ensuring agricultural output, water-saving irrigation technology will inevitably become the mainstream of agricultural irrigation technology. Drip irrigation is a water-saving technology that delivers water directly to the roots of crops through a pipeline system for localized irrigation. Its core is to use capillary tubes and drippers to slowly and evenly moisten the soil in the root zone in the form of water droplets. This technology improves water utilization efficiency and achieves precise water and fertilizer management by continuously supplying water at a small flow rate.

[0003] Existing drip irrigation systems mostly use drippers to drop water onto the soil surface near the crop roots. This causes the water to evaporate due to sun exposure and the dry air from outside, resulting in wasted irrigation water and insufficient irrigation for crops. Utility Model Content

[0004] The purpose of this invention is to provide an irrigation device for crop cultivation that discharges water underground to reduce water evaporation and allow crops to receive more adequate irrigation.

[0005] The crop irrigation device includes a vertically arranged insertion tube, inside which is a movable tube that can move up and down. The upper end of the insertion tube is connected to a flexible hose, which is provided with a connecting component for detachably connecting it to a water supply pipe. The insertion tube is provided with a pushing component for pushing the insertion tube inserted into the soil upward a certain distance. The lower half of the movable tube has several water outlet holes that communicate with each other inside and outside. The bottom of the movable tube is provided with a conical head. A driving component is provided between the insertion tube and the movable tube for driving the lower half of the movable tube to pass through the insertion tube.

[0006] Furthermore, the connecting assembly includes a retainer sleeve fitted onto the unfixed end of the hose, a sealing sleeve independently fitted onto the unfixed end of the hose, the sealing sleeve being located between the water pipe and the retainer sleeve, an opening dividing the unfixed end of the hose into upper and lower parts being provided, and a protrusion that is mirror-symmetrically positioned on the unfixed end of the hose.

[0007] Furthermore, the pushing component includes a fixing plate, which is horizontally fixed on the insertion tube and surrounds the tube body. Several spring pieces are fixed at the bottom of the fixing plate for contacting the ground and elastically pushing the fixing plate upward.

[0008] Furthermore, all the shrapnel pieces are evenly distributed along the circumference, and the shrapnel pieces have an arc-shaped structure.

[0009] Furthermore, the drive assembly includes a spring, an installation groove is provided on the inner wall of the insertion tube around the perimeter, a positioning ring is fitted on the moving tube and can move up and down along the installation groove, and the spring is fitted on the moving tube and is located between the positioning ring and the top of the installation groove.

[0010] Furthermore, a sealing ring for preventing water leakage is provided between the insertion tube and the moving tube, and the sealing ring is located above the spring.

[0011] Furthermore, all water outlets are evenly distributed along the circumference of the moving pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The end of the flexible hose is connected to the water pipe via a connecting assembly. The worker inserts the hose into the soil by hand. Simultaneously, the moving tube, obstructed by the soil, moves further into the hose, with the lower half of the moving tube entering the hose. All the water outlets are blocked by the hose to prevent them from being clogged by soil during insertion. Once the hose is in the correct position, the worker releases the hose, and the pushing assembly pushes the hose upwards a short distance. At the same time, the drive assembly pushes the moving tube downwards, positioning the water outlets outside the hose. Water flows out from each outlet in the moving tube, discharging it underground to irrigate the roots of crops, reducing evaporation and ensuring more adequate irrigation.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0020] This embodiment describes an irrigation device for crop cultivation, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes a vertically arranged insertion tube 1, and a movable tube 7 that can move up and down is installed inside the insertion tube 1. Both the insertion tube 1 and the movable tube 7 are round tubes. The movable tube 7 is located inside the insertion tube 1, and there is a gap between the movable tube 7 and the insertion tube 1, so that the movable tube 7 can move up and down along the insertion tube 1.

[0021] The upper end of the cannula 1 is connected to a flexible tube 2, which is made of materials such as EPDM rubber, nitrile rubber, PVC, and PEX. The flexible tube 2 made of these materials has high flexibility and can be bent and swung freely to adapt to the elongation and shortening of the water pipe under thermal expansion and contraction, ensuring that the cannula 1 will not move.

[0022] To elaborate further, such as Figure 1 and Figure 2 As shown, in this embodiment, a preferred embodiment includes a baffle 3, which is fitted onto the unfixed end of the hose 2. A sealing sleeve 4 is independently fitted onto the unfixed end of the hose 2, and the sealing sleeve 4 is located between the water pipe and the baffle 3. Figure 1 As shown, when the end of the hose 2 is inserted into the connection hole of the water pipe, the sealing sleeve 4 will be located between the retaining sleeve 3 and the wall of the water pipe. The sealing sleeve 4 seals the gap between the retaining sleeve 3 and the wall of the water pipe, preventing water leakage from the water pipe. The unfixed end of the hose 2 has an opening that divides it into upper and lower parts, and the unfixed end of the hose 2 has symmetrical protrusions that are mirror images of each other. Figure 1 As shown, when the end of the hose 2 is inserted into the connection hole of the water pipe, the two protrusions on the end of the hose 2 will be squeezed by the hole wall. The two protrusions will push the upper and lower parts of the end of the hose 2 to swing and bend inward, so that the end of the hose 2 can be successfully inserted into the water pipe. At the same time, the upper and lower parts of the end of the hose 2 will return to their original position due to its own elasticity, so that the two protrusions will be blocked by the water pipe wall, preventing the hose 2 from easily coming out and making it easy to disassemble, thereby connecting the hose 2 to the water pipe. The whole solution constitutes a connecting component for detachably connecting the hose 2 to the water pipe. Of course, the connecting component may also include a C-type buckle. The C-type buckle is fixed on the end of the hose 2. After the end of the hose 2 is inserted into the connection hole of the water pipe, the C-type buckle is engaged with the water pipe, thereby preventing the hose 2 from easily coming out and making it easy to disassemble.

[0023] To elaborate further, such as Figure 1 As shown, this embodiment preferably includes a fixing plate 5, which is horizontally fixed to the insertion tube 1 and surrounds the tube body. Several spring pieces 6 are fixed to the bottom of the fixing plate 5 for contacting the ground and elastically pushing the fixing plate 5 upwards. All spring pieces 6 are evenly distributed along the circumference and have an arc-shaped structure, such as... Figure 1 As shown, the arc-shaped structure facilitates the contact of the spring 6 with the ground and guides the spring 6 to bend. When the insertion tube 1 is inserted into the soil by hand, the unfixed ends of all the spring 6 will first contact the ground. During the continuous downward pressure, all the spring 6 will bend until the unfixed ends of all the spring 6 are in contact with the bottom of the fixing plate 5. After the insertion tube 1 is released by hand, the unfixed ends of all the spring 6 will return to their original shape through their own elasticity. The unfixed ends of all the spring 6 will press against the ground and push the fixing plate 5 to move upward a certain distance. The fixing plate 5 will then drive the insertion tube 1 to move upward a certain distance to reserve space for the insertion of the lower end of the moving tube 7. The whole solution constitutes a pushing component for pushing the insertion tube 1 inserted into the soil upward a certain distance. Of course, the pushing component can also use a foam ring. The fixing plate 5, which surrounds the tube body, is horizontally fixed on the insertion tube 1. The bottom of the fixing plate 5 is glued with a foam ring. The elasticity of the foam ring will push the fixing plate 5 to move upward a certain distance. The fixing plate 5 will then drive the insertion tube 1 to move upward a certain distance.

[0024] The lower half of the movable pipe 7 has several interconnected water outlet holes 11, such as... Figure 2 As shown, when the moving tube 7 is in its initial state, the lower half of the moving tube 7 is located outside the insertion tube 1, and all the water outlets 11 are located outside the insertion tube 1, allowing water in the moving tube 7 to flow out from each water outlet 11. When the insertion tube 1 needs to be inserted into the soil, the moving tube 7 will move into the insertion tube 1 due to the obstruction of the soil, allowing the lower half of the moving tube 7 to enter the insertion tube 1. All the water outlets 11 will be blocked by the insertion tube 1 to prevent the water outlets 11 from being blocked by soil during the insertion process. All the water outlets 11 are evenly distributed along the circumference of the moving tube 7, allowing water to be discharged in different directions, avoiding the absorption of crop roots by a single irrigation direction.

[0025] The bottom of the moving tube 7 is equipped with a conical head, such as Figure 1 and Figure 2 As shown, the conical head helps the moving tube 7 break through the soil, making the insertion process easier and simpler;

[0026] To elaborate further, such as Figure 1 As shown, in this embodiment, a preferred embodiment includes a spring 8. A mounting groove is formed around the inner wall of the insertion tube 1. A positioning ring 9, movable up and down along the mounting groove, is fitted onto the moving tube 7. The spring 8 is fitted onto the moving tube 7 and is located between the positioning ring 9 and the top of the mounting groove. Figure 2As shown, when the moving tube 7 is in its initial state, the spring 8 pushes the positioning ring 9 against the bottom of the mounting groove through its own elasticity, and the lower half of the moving tube 7 extends out of the insertion tube 1, with all the water outlets 11 located outside the insertion tube 1. When the insertion tube 1 needs to be inserted into the soil, the moving tube 7 will move into the insertion tube 1 due to the obstruction of the soil, causing the insertion tube 1 to move the positioning ring 9 upward along the mounting groove, thereby squeezing the spring 8 and compressing it. The lower half of the moving tube 7 then enters the insertion tube 1, and all the water outlets 11 are blocked by the insertion tube 1 to prevent the water outlets 11 from being blocked by soil during insertion. This continues until the unfixed ends of all the spring pieces 6 are in contact with the bottom of the fixing plate 5. After the worker releases the insertion tube 1, all the spring pieces 6 push the insertion tube 1 upward a certain distance through their own elasticity to leave space at the bottom of the pit. During the upward movement of the insertion tube 1, the spring 8 pushes the positioning ring 9 downward along the mounting groove through its own elasticity, and the positioning ring 9 then moves the moving tube 7 downward. The moving tube 7 moves downward, causing the lower half of the tube 7 to protrude through the insertion tube 1. All water outlets 11 are located outside the insertion tube 1, and water inside the moving tube 7 flows out from each water outlet 11, thus discharging water below ground level to irrigate the roots of crops below ground. This scheme constitutes a drive assembly for driving the lower half of the moving tube 7 to protrude through the insertion tube 1. Of course, the drive assembly can also use a tension spring. A mounting groove is opened around the inner side wall of the insertion tube 1. A positioning ring 9 that can move up and down along the mounting groove is fitted on the moving tube 7. One end of the tension spring is connected to the bottom of the mounting groove, and the other end of the tension spring is connected to the positioning ring 9. When the moving tube 7 needs to move downward, the tension spring pulls the positioning ring 9 downward through its own elasticity, and the positioning ring 9 pulls the moving tube 7 downward, causing the lower half of the moving tube 7 to protrude through the insertion tube 1. All water outlets 11 are located outside the insertion tube 1, and water inside the moving tube 7 flows out from each water outlet 11 to irrigate the roots of crops below ground level.

[0027] A sealing ring 10 is provided between the insertion tube 1 and the moving tube 7 to prevent water leakage, such as... Figure 2 As shown, an annular groove is provided on the inner wall of the insertion tube 1, and the sealing ring 10 is engaged in the groove. The sealing ring 10 can seal the gap between the insertion tube 1 and the moving tube 7 to prevent water leakage and prevent soil from entering. The sealing ring 10 is located above the spring 8 to prevent water from corroding the spring 8.

[0028] In actual use, the end of the hose 2 is inserted into the connection hole of the water pipe. The two protrusions on the end of the hose 2 are blocked by the wall of the water pipe to fix the end of the hose 2, thus connecting the hose 2 to the water pipe. Then, the worker inserts the insertion tube 1 into the ground by hand. At the same time, the moving tube 7 is blocked by the soil and moves into the insertion tube 1. The lower half of the moving tube 7 enters the insertion tube 1. All the water outlets 11 are blocked by the insertion tube 1 to prevent the water outlets 11 from being blocked by soil during the insertion process. After being inserted a certain distance, the unfixed ends of all the spring pieces 6 will first contact the ground. During the continuous downward pressure, all the spring pieces 6 will bend until the unfixed ends of all the spring pieces 6 are attached to the bottom of the fixing plate 5. Then, the worker inserts the insertion tube 1 into the ground by hand. When the pressure on the insertion tube 1 is released, the unfixed ends of all the spring pieces 6 return to their original state through their own elasticity. The unfixed ends of all the spring pieces 6 press against the ground, pushing the fixing plate 5 to move upward a certain distance. The fixing plate 5 then moves the insertion tube 1 upward a certain distance to leave space at the bottom of the pit. At the same time as the insertion tube 1 moves upward, the spring 8 pushes the positioning ring 9 downward along the mounting groove through its own elasticity. The positioning ring 9 then moves the moving tube 7 downward, so that the lower half of the moving tube 7 passes through the insertion tube 1. All the water outlets 11 are located outside the insertion tube 1. The water in the moving tube 7 flows out from each water outlet 11, thereby discharging the water below the ground to irrigate the roots of the crops below the ground, reducing water evaporation and allowing the crops to receive more sufficient irrigation.
