Description

Technical Field

[0001] This utility model relates to the field of rice root moisturizing technology, and more specifically, to a root moisturizing device for high-temperature resistant rice. Background Technology

[0002] The core of rice root moisture retention devices lies in precisely delivering and locking water to the root zone. They typically combine underground pipes to slowly release water directly to the vicinity of the roots, reducing water shortage in rice roots caused by excessive evaporation of soil moisture. Furthermore, by precisely delivering water to designated areas, they significantly improve water use efficiency and ensure rice growth.

[0003] Common heat-resistant rice root moisture retention devices can only deliver irrigation water to the rice root zone. In practical applications, the water delivery pipe needs to be inserted into the ground. Since the water delivery pipe is hollow and made of plastic, its strength is insufficient. During the insertion process, it will be squeezed by the soil and tilted excessively, which will cause the water delivery pipe to break and ultimately cause the rice root retention to fail.

[0004] In conclusion, to ensure the survival of rice, it is necessary to address the problem of broken underground water pipes, limiting the tilt angle of the pipes during their insertion into the ground to prevent them from tilting excessively due to soil compression. Utility Model Content

[0005] The present invention provides a root moisture retention device for high-temperature resistant rice, which aims to solve the problem that the water pipe is subjected to excessive tilting due to soil compression during the process of being inserted into the ground, thereby causing the water pipe to break.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a root moisture-retaining device for high-temperature resistant rice, comprising a surface water supply pipe, multiple sets of fixing blocks symmetrically arranged on the surface of the surface water supply pipe, multiple underground water supply pipes installed at the lower end of the surface water supply pipe, connecting blocks installed on the surface of each set of fixing blocks, a forked rod installed at the lower end of two connecting blocks, a connecting rod installed at the lower end of the forked rod, a limiting arc plate installed at the end of the connecting rod near the underground water supply pipe, the limiting arc plate being in contact with the underground water supply pipe, a flow interception mechanism provided on the surface water supply pipe, and a debris backflow prevention mechanism provided on the underground water supply pipe.

[0007] In a preferred embodiment, the sliding end of the intercepting mechanism is connected to the ground water pipe. The intercepting mechanism is used to prevent water from entering the interior of the underground water pipe. The intercepting mechanism includes a blocking component and a limiting component. The sliding end of the blocking component is connected to the ground water pipe. The blocking component is used to block the inlet of the underground water pipe. The limiting component is used to limit the position of the blocking component.

[0008] In a preferred embodiment, the sealing assembly includes a plurality of sliding rods slidably connected to the upper end of the ground water pipe, a sealing block installed at the lower end of the sliding rods, and a positioning plate installed at the upper end of the sliding rods.

[0009] In a preferred embodiment, the limiting assembly includes multiple mounting plates installed on the upper end of the ground water pipe, two unsealing positioning clamps installed on the side of the mounting plates near the sliding rod, and two sealing positioning clamps installed on the side of the mounting plates near the sliding rod, with the positioning plates inserted between the two unsealing positioning clamps.

[0010] In a preferred embodiment, the anti-debris backflow mechanism is used to prevent external debris from entering the interior of the underground water pipe. The anti-debris backflow mechanism includes an outer protective component and a water outlet component. The outer protective component is used to prevent external debris from entering the interior of the underground water pipe, and the water outlet component is used to discharge irrigation water.

[0011] In a preferred embodiment, the outer protective assembly includes a cone-shaped part installed at the lower end of the underground water pipe and a cotton or linen sleeve fitted over the outside of the underground water pipe.

[0012] In a preferred embodiment, the water outlet assembly includes a plurality of water outlet holes symmetrically formed on the surface of the underground water pipe and a filter screen installed inside the water outlet holes.

[0013] In a preferred embodiment, an externally threaded connecting pipe is installed at the input end of the ground water supply pipe, and a positioning rod is installed at the lower end of the externally threaded connecting pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention features a limiting arc plate on the outside of a hollow underground water pipe that needs to be inserted into the ground to restrict its position. This limiting arc plate steadily blocks the underground water pipe from the side, so that even if it encounters soil compression, the lateral pressure of the soil will act on the limiting arc plate, and the force will be transmitted to the fixing block of the water pipe on the ground by the forked rod, forming a multi-level distributed support, reducing the bending stress of the underground water pipe and preventing the underground water pipe from being squeezed and broken.

[0022] 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.

[0023] Refer to the instruction manual appendix Figures 1 to 5 A root moisture retention device for high-temperature resistant rice includes a surface water pipe 1. Multiple sets of fixing blocks 11 are symmetrically arranged on the surface of the surface water pipe 1. Multiple underground water pipes 12 are installed at the lower end of the surface water pipe 1. Connecting blocks 13 are installed on the surface of each set of fixing blocks 11. A forked rod 14 is installed at the lower end of two connecting blocks 13. A connecting rod 15 is installed at the lower end of the forked rod 14. A limiting arc plate 16 is installed at the end of the connecting rod 15 near the underground water pipe 12. The limiting arc plate 16 is in contact with the underground water pipe 12. A flow interception mechanism is provided on the surface water pipe 1, and a backflow prevention mechanism is provided on the underground water pipe 12.

[0024] It should be noted that the limiting arc plate 16 adopts a semi-circular arc structure, with its inner diameter matching the outer diameter of the underground water pipe 12. It forms a triangular support frame through the connecting rod 15 and the forked rod 14. When inserted into the ground, the lateral pressure of the soil acts on the limiting arc plate 16, and the force is transmitted to the fixing block 11 of the ground water pipe 1 by the forked rod 14, forming a multi-level distributed support, which significantly reduces the bending stress of the underground water pipe 12.

[0025] It is worth noting that the fixing block 11 and the connecting block 13 are connected by detachable bolts, which makes it easy to replace the limiting arc plate 16 of different sizes according to the size of the underground water pipe 12.

[0026] Refer to the instruction manual appendix Figures 1 to 3The sliding end of the intercepting mechanism is connected to the ground water pipe 1. The intercepting mechanism is used to prevent water from entering the interior of the underground water pipe 12. The intercepting mechanism includes a blocking component and a limiting component. The sliding end of the blocking component is connected to the ground water pipe 1. The blocking component is used to block the inlet of the underground water pipe 12. The limiting component is used to limit the position of the blocking component.

[0027] It should be noted that the sealing component controls the opening and closing of the inlet of the underground water pipe 12 by vertical sliding, while the limiting component provides two fixed positions to prevent malfunctions caused by water flow impact during irrigation.

[0028] Refer to the instruction manual appendix Figures 1 to 3 The sealing assembly includes multiple sliding rods 211 slidably connected to the upper end of the ground water pipe 1, a sealing block 212 installed at the lower end of the sliding rods 211, and a positioning plate 213 installed at the upper end of the sliding rods 211.

[0029] It should be noted that the sealing block 212 is made of rubber and forms an interference fit with the inlet of the underground water pipe 12. The sliding rod 211 is equipped with a sealing ring at the connection with the ground water pipe 1 to prevent leakage.

[0030] Refer to the instruction manual appendix Figures 1 to 3 The limiting component includes multiple mounting plates 221 installed on the upper end of the ground water pipe 1, two unsealing positioning clamps 222 installed on the side of the mounting plate 221 near the sliding rod 211, and two sealing positioning clamps 223 installed on the side of the mounting plate 221 near the sliding rod 211. The positioning plate 213 is inserted between the two unsealing positioning clamps 222.

[0031] It should be noted that by rotating the positioning plate 213 to disengage it from the two unsealing positioning clamps 222, then pressing the positioning plate 213 to move it to the horizontal position of the two sealing positioning clamps 223, and then rotating the positioning plate 213 to lock it between the two sealing positioning clamps 223, the switching between the locking open valve and locking closed valve states is achieved.

[0032] Refer to the instruction manual appendix Figure 4 The backflow prevention mechanism is used to prevent external debris from entering the interior of the underground water pipe 12. The backflow prevention mechanism includes an outer protective component and a water outlet component. The outer protective component is used to prevent external debris from entering the interior of the underground water pipe 12, and the water outlet component is used to discharge irrigation water.

[0033] It should be noted that the outer protective component covers the outer wall of the underground water pipe 12, preventing soil particles, roots, etc. from intruding, and the water outlet component has a built-in filter structure to prevent backflow and blockage.

[0034] It is worth noting that the cotton and linen cover 312 is biodegradable and decomposes naturally after the rice is harvested, reducing the environmental burden.

[0035] Refer to the instruction manual appendix Figure 4 The outer protective component includes a cone 311 installed at the lower end of the underground water pipe 12 and a cotton and linen sleeve 312 fitted on the outside of the underground water pipe 12.

[0036] It should be noted that the cone head 311 is made of stainless steel, which makes it easy to insert into hard soil, while the cotton and linen sleeve 312 has both water permeability and impurity blocking functions.

[0037] Refer to the instruction manual appendix Figure 4 The water outlet assembly includes multiple water outlet holes 321 symmetrically opened on the surface of the underground water pipe 12 and a filter screen 322 installed inside the water outlet holes 321.

[0038] It should be noted that the water outlet 321 is used to discharge irrigation water, and the filter screen 322 prevents sediment from seeping back in. The filter screen 322 is in contact with the pipe wall to prevent roots from entering through the pores and causing blockage.

[0039] Refer to the instruction manual appendix Figure 2 The input end of the ground water supply pipe 1 is equipped with an external threaded connecting pipe 17, and the lower end of the external threaded connecting pipe 17 is equipped with a positioning rod 18.

[0040] It should be noted that the external threaded connecting pipe 17 is compatible with standard irrigation hose connectors, and the positioning rod 18 is inserted into the soil to help fix the ground water delivery pipe 1 and prevent the pipe from shaking during irrigation.

[0041] Working principle: During installation, the external irrigation water source is connected via the external threaded connecting pipe 17. Simultaneously, the positioning rod 18 is inserted into the ground to fix the surface water pipe 1. The underground water pipe 12 is vertically inserted into the soil around the rice roots. Its bottom cone 311 assists in breaking through the soil. The cotton and linen sleeve 312 forms a permeable isolation layer in the soil, preventing roots or debris from intruding into the pipe wall. During insertion, the limiting arc plate 16 tightly fits against the outer wall of the underground water pipe 12. The lateral soil pressure is transmitted to the connecting block 13 and the fixing block 11 via the connecting rod 15 and the forked rod 14. Finally, the surface water pipe 1 disperses the supporting force, avoiding... To prevent the underground water pipe 12 from tilting or breaking due to excessive soil compression, if irrigation is not needed in a certain area, rotate the positioning plate 213 to disengage it from the unsealing positioning clamp 222, press down the sliding rod 211 to insert the sealing block 212 into the inlet of the underground water pipe 12, and then rotate the positioning plate 213 again to lock it between the two sealing positioning clamps 223. When water flows into the surface water pipe 1, it will not enter the underground water pipe 12 because the inlet is blocked by the sealing block 212. Other underground water pipes 12 that are not blocked by the sealing block 212 will discharge irrigation water to the root soil through the outlet hole 321.

[0042] 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.
