Description

Technical Field

[0001] This utility model relates to the field of rice root zone irrigation technology, and more specifically, to a root zone irrigation device for drought-resistant rice that saves water. Background Technology

[0002] Common root zone irrigation devices used for drought-resistant rice can only irrigate the roots of rice plants, but lack the function of adjusting the water storage position. In actual irrigation, because the rice planting position is not fixed, the pipes are not laid at fixed equal intervals, resulting in some pipe inlets being too far from the water outlets to connect. Ultimately, this causes some rice plants to suffer from regional water shortages due to lack of irrigation.

[0003] In summary, in order to overcome the shortcomings of existing drought-resistant rice root zone irrigation devices in terms of adaptability, it is necessary to solve the drawback of fixed and non-adjustable water delivery pipe interface positions, so that the water storage point positions can be flexibly adjusted according to the actual planting layout, thereby avoiding regional irrigation water shortage problems caused by difficulties in pipe connection.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 A root zone irrigation device for drought-resistant rice cultivation includes a protective shell 1. A sliding groove 11 is formed on the surface of the protective shell 1. Multiple sliding plates 12 are installed inside the sliding groove 11. Engaging frames 13 are symmetrically installed at the upper and lower ends of each sliding plate 12, and the engaging frames 13 are slidably connected to the sliding groove 11. A water delivery connector 14 is installed on the surface of each sliding plate 12. An adjusting rod 15 is installed on the side of each sliding plate 12 away from the water delivery connector 14. A first pair of connectors 16 is installed on the outer side of the water delivery connector 14. A water delivery hose 17 is installed on the side of the first pair of connectors 16 away from the sliding plate 12. A second pair of connectors 18 is installed at the water inlet end of the water delivery hose 17. A protective cover 22 is installed at the upper end of the protective shell 1. A water delivery mechanism is provided on the protective shell 1, and an irrigation mechanism is provided on the sliding plate 12.

[0023] It should be noted that the sliding connection between the sliding groove 11 and the locking frame 13 constitutes a horizontal adjustment mechanism. By pulling the adjustment rod 15, the sliding plate 12 can be moved horizontally along the sliding groove 11, so as to flexibly adjust the position of the water supply connector 14. The water supply hose 17 is made of a stretchable soft material to ensure the water circuit connectivity when the sliding plate 12 is displaced.

[0024] It is worth noting that the protective cover 22 and the protective shell 1 adopt a snap-fit ​​sealing design, and the multi-movement sliding plate 12 has independent adjustment characteristics, making the device adaptable to the ridge layout of rice fields with non-equidistant planting.

[0025] Refer to the instruction manual appendix Figures 1 to 3 The output end of the water delivery mechanism is connected to the water delivery hose 17. The water delivery mechanism is used to deliver irrigation liquid to the water delivery hose 17. The water delivery mechanism includes a diversion component and a confluence component. The output end of the diversion component is connected to the second connector 18. The diversion component is used to divert the confluenced irrigation liquid into multiple water delivery hoses 17. The output end of the confluence component is connected to the diversion component. The confluence component merges the two streams of irrigation liquid together.

[0026] It should be noted that the manifold assembly premixes the clean water and fertilizer and then delivers them to the diversion assembly. The diversion assembly achieves zoned irrigation through multi-channel output. The two components work together to improve water and fertilizer utilization. The fertilizer pipe 323 in the manifold assembly is located on the side of the clean water pipe 322, which uses the shear force of the water flow to enhance the mixing effect and avoid the risk of blockage.

[0027] Refer to the instruction manual appendix Figure 3 The diversion assembly includes a diversion pipe 311 installed inside the protective housing 1, a plurality of diversion connectors 312 installed on the surface of the diversion pipe 311, and an inlet pipe 313 installed on the surface of the diversion pipe 311. The diversion connectors 312 are connected to the second pair of connectors 18.

[0028] It should be noted that the diversion pipe 311 has a branched structure, the number of diversion joints 312 corresponds one-to-one with the sliding plate 12, and the inlet pipe 313 is located in the middle of the diversion pipe 311 to reduce water pressure loss.

[0029] Refer to the instruction manual appendix Figure 3 The manifold assembly includes a manifold 321 installed at the upper end of the inlet pipe 313, a clean water pipe 322 installed at the upper end of the manifold 321, and a fertilizer pipe 323 installed on the surface of the clean water pipe 322.

[0030] It should be noted that the fertilizer pipe 323 and the water pipe 322 intersect in a Y-shape at the manifold 321. The manifold 321 is equipped with a turbulence plate to enhance the uniformity of water and fertilizer mixing and avoid excessive local concentration that could burn the rice roots.

[0031] Refer to the instruction manual appendix Figures 1 to 5 The input end of the irrigation mechanism is connected to the sliding plate 12. The irrigation mechanism is used to irrigate the root zone of rice. The irrigation mechanism includes a surface pipe assembly and an underground pipe assembly. The input end of the surface pipe assembly is connected to the sliding plate 12. The surface pipe assembly is used to transport irrigation liquid to the underground pipe assembly. The input end of the underground pipe assembly is connected to the surface pipe assembly. The underground pipe assembly is used to transport irrigation liquid to the root zone of rice.

[0032] It should be noted that the ground pipeline assembly delivers irrigation fluid to the underground pipeline assembly, and the root zone pipe 421 is buried underground to reach the dense root zone of rice, thus reducing surface evaporation loss through zoned irrigation.

[0033] It is worth noting that the surface and underground pipelines are connected by a quick-release system, which makes it easy to adjust the burial depth according to the rice growth cycle.

[0034] Refer to the instruction manual appendix Figures 4 to 5 The ground piping assembly includes a plug 411 mounted on the surface of the sliding plate 12 and an irrigation pipe 412 mounted on the outside of the plug 411.

[0035] It should be noted that the plug 411 and the water supply connector 14 are connected by a threaded seal to ensure that the high-pressure water flow does not leak. The length of the irrigation pipe 412 can be customized to adapt to different field widths.

[0036] Refer to the instruction manual appendix Figure 5 The underground pipeline assembly includes multiple root zone pipes 421 installed on the surface of the irrigation pipe 412, multiple irrigation holes 422 opened on the surface of the root zone pipes 421, and a positioning plug 423 installed at the lower end of the root zone pipes 421.

[0037] It should be noted that the irrigation holes 422 are evenly distributed on the outside of the root zone tube 421, the positioning plug 423 is a conical stainless steel structure, which is easy to insert into the soil layer, and the inner wall of the root zone tube 421 is covered with a non-woven filter layer to prevent soil backflow.

[0038] Refer to the instruction manual appendix Figures 1 to 2 The protective housing 1 has multiple support blocks 19 installed inside. The upper end of the support block 19 is equipped with a support arc plate 20. The diversion pipe 311 is inserted into the support arc plate 20. The lower end of the protective housing 1 is equipped with four positioning rods 21 in a rectangular shape.

[0039] It should be noted that the supporting arc plate 20 supports the diversion pipe 311 and limits the position of the diversion pipe 311. The four positioning rods 21 form a stable support surface, and the position of the protective shell 1 is limited by inserting the positioning rods 21 into the soil. This method is especially suitable for paddy and dryland rotation fields.

[0040] Working principle: Clean water and liquid fertilizer are initially mixed by entering the manifold 321 through the clean water pipe 322 and fertilizer pipe 323 respectively. The resulting irrigation liquid is transported through the inlet pipe 313 to the branch pipe 311 inside the protective shell 1. The branch pipe 311 divides the irrigation liquid through multiple branch connectors 312 distributed on its surface. Each branch connector 312 is connected to the water delivery hose 17 through the second pair of connectors 18. The outlet of the water delivery hose 17 is connected to the water delivery connector 14 on the sliding plate 12 through the first pair of connectors 16. When the rice planting layout causes a mismatch in the position of the water delivery interface, the sliding plate 12 is driven to move laterally along the sliding groove 11 by pulling the horizontal adjustment rod 15. The locking frame 13 slides within the sliding groove 11 to achieve the positioning adjustment of the water delivery connector 14. Due to its flexible characteristics, the water delivery hose 17 automatically adapts to displacement changes. The adjusted irrigation liquid enters the irrigation pipe 412 through the plug 411, and then flows to multiple root zone pipes 421 buried underground. The liquid seeps directly into the rice root zone soil through the irrigation holes 422 opened on the surface of the root zone pipe 421. The positioning plug 423 at the end of the root zone pipe 421 ensures its stable positioning underground. The protective shell 1 is fixed to the ground by the four positioning rods 21 at the bottom. The internal support block 19 and support arc plate 20 support the diversion pipe 311. The protective cover 22 closes the top of the shell to provide protection.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
