Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment technology, and specifically to an irrigation device for corn cultivation. Background Technology

[0002] Corn is an important food crop, and controlling irrigation water volume is a crucial factor in ensuring its yield during cultivation. Drip irrigation, as a water-saving irrigation technology, is widely used in corn cultivation. By controlling the amount of irrigation water, it ensures that corn has sufficient water during the sowing, jointing, and tasseling stages, while preventing problems such as root rot, lodging, drought, and waterlogging, resulting in fuller corn kernels and increased yield.

[0003] Drip irrigation water mainly comes from rainwater collected in fields, well water, or river water. These water sources usually contain impurities such as silt and suspended solids. As the drip irrigation device is used for a long time, these impurities will gradually accumulate in the drip irrigation device, forming impurity blockage and / or chemical scaling and other particulate matter. The presence of these particulate matter can easily lead to a slow water flow rate in the drip irrigation device and may clog the drip head, affecting the water flow rate, irrigation effect, and controllability of the irrigation process.

[0004] Existing technologies often employ external multi-stage filtration systems to solve clogging problems. However, corn is a field crop with low yields, and multi-stage filtration systems increase planting costs and are difficult for ordinary farmers to maintain.

[0005] Therefore, providing a low-cost irrigation device that can avoid clogging is of great significance for the field of water-saving irrigation for corn. Summary of the Invention

[0006] In view of this, the present invention provides an irrigation device for corn cultivation, specifically a dripper assembly comprising a connecting section, a flow section, and a water outlet section connected in sequence; the flow section is provided with a water guide plate, the water outlet section includes a water guide pipe, and the end of the water guide pipe is provided with a buffer trough. This irrigation device, while effectively solving the problem of drip irrigation clogging and ensuring the irrigation effect and controllability of corn, significantly reduces the cost of use and maintenance difficulty, adapts to the actual needs of corn field planting, has a reasonable structure, is convenient to use, and has strong stability, and has important value for promotion and application, and has positive significance for the technological upgrading of the field of corn water-saving irrigation.

[0007] The technical solution of the present invention is as follows: An irrigation device for corn cultivation includes a drip irrigation tape and a dripper assembly disposed on the drip irrigation tape; The drip irrigation tape has a hollow structure with water channels inside; The dripper assembly includes a connecting section, a flow section, and a water outlet section connected in sequence; The interior of the flow section is an isosceles trapezoidal cavity, with a structure that is narrower at the top and wider at the bottom; When irrigation water enters the flow section, the cavity structure, which is narrow at the top and wide at the bottom, creates a velocity difference between the upper and lower water flows, causing the water to swirl automatically. This reduces the deposition of particulate impurities at the bottom of the flow section, preventing the accumulation of impurities over long-term use that would slow down the water flow and ensuring irrigation effectiveness and controllability of the irrigation process. Water guide plates are provided on the inner side of the flow section, and the water guide plates are arranged alternately on the two sides of the flow section. The arrangement of the water guide plates forms an S-shaped water flow channel in the horizontal direction within the flow section. When irrigation water moves along this S-shaped water flow channel, the turbulence design of the water guide plates, combined with the design of the trapezoidal cavity, enhances the turbulence effect of the water flow, further reduces the accumulation of particulate impurities in the flow section, ensures the water flow speed, and thus improves the controllability of the irrigation process. The water outlet section includes a tapering water guide pipe and a drip head; A through hole A is provided on the bottom edge of the water pipe, and a buffer groove is installed on the outer side of the bottom edge of the water pipe. The top surface of the buffer groove is located around the through hole A and is sealed to the bottom edge of the water pipe. When irrigation water carrying particulate impurities reaches the outlet section, the water velocity decreases, causing the particulate impurities to gradually accumulate and flow along the inner bottom edge of the tapered water guide pipe through through-hole A into the buffer tank. Since the height of the buffer tank is lower than the height of the drip head, the particulate impurities have difficulty entering the drip head, thus reducing the risk of blockage. When there are too many particulate impurities in the buffer tank, it can be disassembled, cleaned, and reinstalled for reuse. This effectively reduces the operating cost of the irrigation system while ensuring irrigation effectiveness and controllability.

[0008] Preferably, the connecting section is trumpet-shaped and threadedly connected to the drip irrigation tape; in use, the dripper assembly is connected at the corresponding position according to the furrow spacing; the trumpet-shaped connecting section facilitates the smooth flow of irrigation water from the drip irrigation tape into the dripper assembly.

[0009] Preferably, the water guide plate is inclined; the water guide plate is inclined in the direction of irrigation water flow, which facilitates the movement of particulate impurities with the irrigation water towards the outlet section, reduces the accumulation of particulate impurities in the flow section, and ensures the water flow speed.

[0010] Preferably, the free end face of the water guide plate is close to the middle of the bottom surface of the flow section, and the top surface of the water guide plate is connected to the inner top surface of the flow section, and the bottom surface of the water guide plate is connected to the inner bottom surface of the flow section; this arrangement can make the irrigation water flow in an S-shape, avoid the accumulation of particulate impurities, and ensure the water flow speed.

[0011] Preferably, a protrusion is provided on the free end face of the water guide plate to further interfere with the water flow, so that particulate impurities can move towards the outlet section along with the irrigation water.

[0012] Preferably, a through hole B is provided on one side of the flow section, and the inlet end of the water pipe corresponds to the position of the through hole B; irrigation water enters the water pipe through the through hole B of the flow section, and then is discharged into the furrow through the drip head.

[0013] Preferably, a baffle is provided on the outer side of the bottom edge of the water guide pipe. One side of the baffle is axially connected to the side of the water guide pipe near the drip head, and the other side is connected to the side of the water guide pipe near the flow section via a pull rope, so that there is an inlet and outlet channel between the baffle and the buffer tank, and an inlet and outlet channel between the baffle and the through hole A. The positions of the baffle and the through hole A correspond, and the baffle is provided with a through hole C. When irrigation water enters the water guide pipe, particulate impurities will enter the buffer tank and settle due to gravity. By using the baffle, the agitation of particulate impurities can be reduced so that they enter the drip head for discharge, thereby reducing the problem of drip head blockage.

[0014] Preferably, a groove A is provided on the outer side of the bottom edge of the water pipe, and a positioning post is provided on the top surface of the buffer groove. The position of the positioning post corresponds to the position of the groove A. During installation, the positioning post is first inserted into the groove A to preliminarily determine the position of the buffer groove, and then it is fixed.

[0015] Preferably, grooves B are provided on both sides of groove A, and grooves A and grooves B are connected; a protrusion is provided on the side of the positioning post, and the position of the protrusion corresponds to the position of groove B, which facilitates a more stable pre-fixing process for the buffer groove.

[0016] Preferably, an annular washer is provided on the top surface of the buffer tank. The washer improves the tightness of the connection between the buffer tank and the water pipe, reducing the possibility of water leakage.

[0017] Preferably, a hook is provided on the outer side of the bottom edge of the water pipe, and a buckle is provided on the outer side of the buffer groove, with the buckle and the hook corresponding to each other. After the buffer groove is pre-fixed to the outside of the water pipe, it can be locked by using the buckle and the hook, which has the advantage of facilitating disassembly.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the flow section adopts an isosceles trapezoidal cavity structure that is narrower at the top and wider at the bottom, causing the incoming irrigation water to form an automatic swirling flow. Utilizing the velocity difference between the upper and lower water layers, it reduces the deposition of particulate impurities at the bottom of the flow section, preventing a decrease in water flow velocity due to impurity accumulation. The staggered guide plates on the inner side of the flow section form an S-shaped water channel, which, combined with the swirling effect of the trapezoidal cavity, enhances the turbulent flow, further reducing the adhesion and accumulation of particulate impurities within the flow section and ensuring stable water flow velocity. The coordinated design of the tapered guide pipe, buffer trough, and baffle in the outlet section ensures that, after the water velocity decreases, the impurities carrying the irrigation water enter the buffer trough through the through-hole A along the bottom edge of the guide pipe and are intercepted. Furthermore, the height of the buffer trough is lower than the drip line. The water head effectively prevents impurities from entering the drip head and causing blockages; the baffle further prevents impurities in the buffer trough from being stirred up and entering the drip head, providing double protection and improving anti-blockage reliability; by utilizing the synergistic effect of the structure, the core problem of easy clogging in existing drip irrigation devices is solved, ensuring a stable supply of irrigation water and controllable flow rate, which can accurately meet the water needs of corn at different growth stages, avoiding problems such as root rot and lodging caused by drought, flooding, and uneven water supply, helping corn kernels to be full and increasing yield; and by achieving controllability of the irrigation process, irrigation water can be better controlled in the furrows, avoiding problems such as insufficient irrigation due to too little irrigation water and excessive irrigation water overflowing the ridges and affecting the health of corn roots.

[0019] 2. In this invention, the connecting section adopts a trumpet-shaped design and is threadedly connected to the drip irrigation tape. This facilitates the smooth entry of irrigation water into the dripper assembly and allows for flexible installation of the dripper assembly at the corresponding position on the drip irrigation tape according to the spacing between corn furrows, adapting to different planting densities and ridge spacing requirements. The inclined setting, free end face position design, and protruding structure of the water guide plate further optimize the water flow path, promote the movement of impurities towards the water outlet section with the water flow, and reduce accumulation. The buffer trough, through the structural design of positioning columns, grooves, buckles, and hooks, enables quick installation and disassembly, simplifying operation and reducing the difficulty of use and maintenance.

[0020] 3. The irrigation device of the present invention effectively solves the problem of drip irrigation device clogging, ensures the irrigation effect and controllability of corn, significantly reduces the cost of use and maintenance difficulty, adapts to the actual needs of corn field planting, has a reasonable structure, is easy to use, and has strong stability. It has important value for promotion and application, and has positive significance for the technological upgrading of the corn water-saving irrigation field. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of this invention will be clearly and completely described below in conjunction with the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0029] Combination Figures 1-5 The present invention provides an irrigation device for corn cultivation, including a drip irrigation tape 1 and a dripper assembly disposed on the drip irrigation tape 1; The drip irrigation tape 1 has a hollow structure, and its interior is a water flow channel; The dripper assembly includes a connecting section 201, a flow section 202, and a water outlet section 203 connected in sequence. The connecting section 201 is trumpet-shaped and is threadedly connected to the drip irrigation tape 1. Those skilled in the art can install it themselves according to actual needs. In use, the dripper assembly is connected at the corresponding position according to the furrow spacing. The trumpet-shaped connecting section 201 facilitates the smooth flow of irrigation water from the drip irrigation tape 1 into the dripper assembly. The interior of the flow section 202 is an isosceles trapezoidal cavity 2021, with a structure that is narrower at the top and wider at the bottom; When irrigation water enters the flow section 202, the upper narrow and lower wide cavity structure 2021 creates a velocity difference between the upper and lower water flow, thereby causing the water to automatically swirl, reducing the deposition of particulate impurities at the bottom of the flow section 202, avoiding the accumulation of impurities over long-term use that would lead to a slow water flow, and ensuring irrigation effect and controllability of the irrigation process. A water guide plate 2022 is provided on the inner side of the flow section 202, and the water guide plate 2022 is located on both sides of the flow section 202; the water guide plates 2022 on the two sides are staggered. The water guide plate 2022 is inclined. In this embodiment, the inclination angle of the water guide plate 2022 is 75°. The water guide plate 2022 is inclined in the direction of irrigation water flow, which is conducive to the movement of particulate impurities with irrigation water towards the outlet section 203, reducing the accumulation of particulate impurities in the flow section 202 and ensuring the water flow speed. The free end face of the water guide plate 2022 is close to the middle of the bottom surface of the flow section 202, and the top surface of the water guide plate 2022 is connected to the inner top surface of the flow section 202, and the bottom surface of the water guide plate 2022 is connected to the inner bottom surface of the flow section 202. This arrangement can make the irrigation water flow in an S-shape, avoid the accumulation of particulate impurities, and ensure the water flow speed. The water guide plate 2022 is set to form an S-shaped water flow channel in the horizontal direction within the flow section 202. When the irrigation water moves along the S-shaped water flow channel, the turbulence design of the water guide plate 2022, together with the design of the trapezoidal cavity 2021, enhances the turbulence effect of the water flow, further reduces the accumulation of particulate impurities in the flow section 202, ensures the water flow speed, and thus improves the controllability of the irrigation process. The water guide plate 2022 is distributed within the first 3 / 4 of the length of the flow section 202 (based on the length of the flow section 202), and the remaining 1 / 4 of the length of the flow section 202 serves as a buffer zone; the first section through which the irrigation water passes is the front section. A through hole B2023 is provided on one side of the flow section 202, and the through hole B2023 is located in the buffer zone; and the through hole B2023 is located on the side of the flow section 202 where the last water guide plate 2022 is provided. Combination Figure 1 In this embodiment, there are five water guide plates 2022 on each of the two sides; A protrusion 3 is provided on the free end face of the water guide plate 2022 to further interfere with the water flow, so that particulate impurities can move towards the water outlet section 203 along with the irrigation water. The water outlet section 203 includes a tapered water guide pipe 2031 and a drip head 2032; The position of the water guide pipe 2031 corresponds to the position of the through hole B2023; after being guided by the last water guide plate 2022, the irrigation water enters the buffer zone and tends to stabilize; then it enters the water guide pipe 2031 through the through hole B2023 of the flow section 202, and finally exits through the drip head 2032; To prevent irrigation water from flowing back into the drip head 2032 from the outside, a through groove 4 is provided on the outside of the drip head 2032. The length of the through groove 4 is the same as the length of the drip head 2032, so as to prevent water from flowing back into the drip head 2032. A through hole A5 is provided on the bottom edge of the water pipe 2031. A buffer groove 6 is installed on the outer side of the bottom edge of the water pipe 2031. The top surface of the buffer groove 6 is located around the through hole A5 and is sealed to the bottom edge of the water pipe 2031. A baffle 7 is provided on the outer side of the bottom edge of the water pipe 2031. One side of the baffle 7 is hinged to the water pipe 2031 and the connection position is close to the drip head 2032. The other side is connected to the water pipe 2031 through the pull rope 8 and the connection position is close to the flow section 202. This creates an inlet and outlet channel between the baffle 7 and the buffer tank 6, and an inlet and outlet channel between the baffle 7 and the through hole A5. The positions of the baffle 7 and the through hole A5 correspond, and the baffle 7 is provided with a through hole C9. When irrigation water enters the water pipe 2031, particulate impurities will enter the buffer tank 6 and settle due to gravity. By using the baffle 7, the amount of particulate impurities stirred up and entering the drip head 2032 for discharge can be reduced, thereby reducing the problem of clogging of the drip head 2032. A groove A10 is provided on the outer side of the bottom edge of the water pipe 2031, and a positioning post 11 is provided on the top surface of the buffer groove 6. The position of the positioning post 11 corresponds to the position of the groove A10. During installation, the positioning post 11 is first inserted into the groove A10 to preliminarily determine the position of the buffer groove 6, and then it is fixed. Grooves B12 are provided on both sides of groove A10, and grooves A10 and grooves B12 are connected; protrusions 13 are provided on the side of positioning post 11, and the position of protrusions 13 corresponds to the position of grooves B12, which helps to make the pre-fixing process of buffer groove 6 more stable. An annular washer 14 is provided on the top surface of the buffer tank 6. The washer 14 improves the tightness of the connection between the buffer tank 6 and the water pipe 2031 and reduces the possibility of water leakage. A hook 15 is provided on the outer side of the bottom edge of the water pipe 2031, and a buckle 16 is provided on the outer side of the buffer groove 6. The buckle 16 and the hook 15 are positioned correspondingly. After the buffer groove 6 is pre-fixed to the outside of the water pipe 2031, it can be locked by using the buckle 16 and the hook 15, which has the advantage of facilitating disassembly. After the irrigation water passes through the S-shaped water flow channel, it enters the buffer zone to slow down. It then uses the force of the irrigation water to enter the water guide pipe 2031 and then enters the buffer tank 6. The buffer tank 6 traps particulate impurities, while the irrigation water enters the furrow through the drip head 2032. During use, when irrigation water carrying particulate impurities reaches the outlet section 203, the water velocity decreases, causing the particulate impurities in the irrigation water to gradually accumulate and flow along the inner bottom edge of the tapered water guide pipe 2031 through the through hole A5 into the buffer tank 6. Since the height of the buffer tank 6 is lower than the height of the drip head 2032, the particulate impurities are difficult to enter the drip head 2032, thereby reducing the blockage of the drip head 2032 by particulate impurities. When there are too many particulate impurities in the buffer tank 6, the buffer tank 6 can be disassembled, cleaned, and reinstalled for reuse. While ensuring irrigation effect and controllability, the operating cost of the irrigation device can be effectively reduced.
