Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to a drip irrigation device for pomegranate tree planting. Background Technology

[0002] Pomegranate trees, being shallow-rooted fruit trees, have a "moisture-loving, water-intolerant" characteristic in their water requirements. A stable water supply is needed during the budding, flowering, and fruit enlargement stages to ensure fruit set and quality, while waterlogged soil easily leads to root rot. Drip irrigation, due to its precise water delivery and reduced water waste, has become the core irrigation method for pomegranate tree cultivation. However, existing pomegranate drip irrigation equipment typically has only one sprinkler head per point, which not only limits irrigation to a single location but also renders the current point ineffective when the sprinkler head becomes clogged. Furthermore, adjusting the drip irrigation capacity usually requires adjustments at different points, which is time-consuming when dealing with a large number of pomegranate trees. Additionally, drip irrigation sprinklers are prone to clogging due to soil cover and impurities, leading to irrigation failure, and sprinklers close to the ground can interfere with field operations such as weeding and fertilization.

[0003] To address the above problems, this invention proposes a drip irrigation device for pomegranate tree planting. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing drip irrigation equipment for pomegranate trees, which can only achieve drip irrigation at a single point. When the nozzle at this point is blocked, the current point loses its drip irrigation effect. In addition, the drip irrigation capacity generally needs to be adjusted at different points. When dealing with a large number of pomegranate trees, it takes a lot of time to adjust the drip irrigation capacity separately. Furthermore, the drip irrigation nozzle is prone to irrigation failure due to soil covering and impurities. Also, when the nozzle is close to the ground, it will interfere with field operations such as weeding and fertilizing. Therefore, this invention proposes a drip irrigation device for pomegranate tree planting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drip irrigation device for pomegranate tree planting includes a drip irrigation device, the output port of which is connected to multiple diverting drip irrigation mechanisms;

[0007] The diversion drip irrigation mechanism includes a drip irrigation diversion pipe that is connected to the output port of the drip irrigation device. The drip irrigation diversion pipe is provided with multiple diversion pipe support components. The drip irrigation diversion pipe is connected to the drip head structure of multiple dual-head drip irrigation components. A drip head structure adjustment component is provided below the drip irrigation diversion pipe. The movable bar of the drip head structure adjustment component is provided with multiple drive tooth segments. The drive tooth segments mesh with the transmission gear of the dual-head drip irrigation component. The dual-head drip irrigation component is provided with two drip head unblocking components.

[0008] Preferably, the diversion tube support assembly includes a fixing tube clamp structure, which is fixedly installed on the drip irrigation diversion tube. A diversion tube fixing cone is fixedly connected below the fixing tube clamp structure, and a cone reinforcement plate is fixedly connected below the diversion tube fixing cone.

[0009] Preferably, the drip head structure adjustment assembly includes an adjustment screw and two fixed brackets. One end of the adjustment screw is fixedly connected to a handle, and the adjustment screw is rotatably mounted on the two fixed brackets via two bearings.

[0010] Preferably, an adjusting nut is threaded onto the adjusting screw, an adjusting seat is fixedly mounted on the adjusting nut, an indicator ring and a movable bar are fixedly connected above the adjusting seat, and the movable bar slides through multiple fixed pipe clamp structures.

[0011] Preferably, a plurality of guide grooves are provided above the movable strip, the guide grooves are slidably connected to the guide strip, and the guide strip is fixedly connected to the drip irrigation diversion pipe.

[0012] Preferably, an observation port is provided above the indicator ring, the drip irrigation diversion tube is sleeved on the drip irrigation diversion tube, and three identification plates are provided on the drip irrigation diversion tube.

[0013] Preferably, the dual-head drip irrigation assembly includes two drip head structures, each with a valve core structure inside. The two valve core structures are configured to open and close in opposite directions. A drive valve rod is provided on one side of each valve core structure. The two drive valve rods extend out of the drip head structure and are connected to the same valve seat. A transmission gear is fixedly installed on the valve seat.

[0014] Preferably, the drip irrigation head unblocking assembly includes two fixing members, which are fixedly connected in the drip irrigation head structure. One end of each fixing member is fixedly connected to a fixing cavity. The fixing cavity has an upper wide cavity and a lower narrow cavity, which are connected. An upper piston is provided in the upper wide cavity. A return spring and a piston rod are fixedly connected above the upper piston. The piston rod slides in a sealing sleeve. The sealing sleeve is fixedly installed above the fixing cavity and is fixedly connected to one end of the return spring.

[0015] Preferably, the top end of the piston rod is provided with a ball bearing structure, and the movement of the valve core structure causes the spherical surface of the valve core structure to press down on the ball bearing structure.

[0016] Preferably, a lower piston is provided in the lower narrow cavity, and a drain needle is fixedly connected below the lower piston, with the drain needle penetrating the fixed cavity.

[0017] Compared with the prior art, the present invention provides a drip irrigation device for pomegranate tree planting, which has the following beneficial effects:

[0018] 1. This drip irrigation equipment for pomegranate tree planting, by setting two drip head structures at a single point and driving the drive gear segment and transmission gear through the drip head structure adjustment component, can simultaneously control multiple drip head structures. It can not only achieve simultaneous drip irrigation operation of two drip head structures at the same location, but also flexibly switch the working state of the two drip head structures, avoiding the problem of a single drip head structure being blocked and affecting normal drip irrigation. Moreover, the entire operation is simple and convenient, ensuring the stable and efficient operation of the drip irrigation system, and enhancing the adaptability of the drip irrigation system to different planting environments and crop growth stages.

[0019] 2. This drip irrigation equipment for pomegranate tree planting uses two drip head structures that can be switched to allow the valve core structure to drive the ball bearing structure and piston rod. The upper piston uses air pressure to control the movement of the lower piston, which in turn unclogs the drip inlet of the drip head structure, removing residual impurities. When the drip head structure is idle, the unclogging needle can be inserted into the drip inlet to form a sealing structure, preventing impurities from entering and causing blockage. This design can solve the problem of easy clogging of traditional drip head structures and the impact of clogging on normal operation, further reducing field operation and maintenance costs.

[0020] 3. This drip irrigation equipment for pomegranate tree planting can control the drive gear section to adjust the dual-head drip irrigation component through the drip head structure adjustment component. This allows the two drip heads of the dual-head drip irrigation component to switch between operations. During the switching process, the drip head unblocking component can also be linked to unclog the drip inlets of the drip head structure. No additional power source is required, and no separate maintenance is needed. The drip head unblocking component ensures the smooth flow of the drip head structure and ensures stable irrigation effect after the dual-point switching, avoiding the problem of insufficient water supply on one side due to drip inlet blockage. This comprehensively ensures that the irrigation effect remains stable after switching. Through the coordinated operation of the dual-point switching irrigation and unblocking system, an integrated irrigation process of precise control, automatic cleaning, and convenient operation and maintenance is achieved.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Example 1: Refer to Figures 1-9 A drip irrigation device for pomegranate tree planting includes a drip irrigation device 100, the output port of which is connected to a plurality of diverting drip irrigation mechanisms 200;

[0035] The diversion drip irrigation mechanism 200 includes a drip irrigation diversion pipe 201, which is connected to the output port of the drip irrigation device 100. Water can be output from the drip irrigation device 100, and the liquid can be diverted through the drip irrigation diversion pipe 201 to facilitate diversion drip irrigation operations and increase the drip irrigation area. Multiple diversion pipe support assemblies 202 are provided on the drip irrigation diversion pipe 201. Each diversion pipe support assembly 202 includes a fixing pipe clamp structure 2021, which is fixedly installed on the drip irrigation diversion pipe 201. A diversion pipe fixing cone 2022 is fixedly connected below the fixing pipe clamp structure 2021. A cone-shaped reinforcement plate 2023 is fixedly connected to the bottom of 2. The diversion pipe fixing cone 2022 can be connected to the drip irrigation diversion pipe 201 through the fixing pipe clamp structure 2021. The bottom of the diversion pipe fixing cone 2022 is cone-shaped, so it can be easily inserted into the soil. At the same time, the cone-shaped reinforcement plate 2023 can contact the ground surface, so that the cone-shaped reinforcement plate 2023 increases the stability of the diversion pipe fixing cone 2022 and prevents the diversion pipe fixing cone 2022 from tipping over. This ensures that the diversion pipe fixing cone 2022 provides stable support for the drip irrigation diversion pipe 201. The drip irrigation diversion pipe 201 is connected to the drip irrigation head structure 2051 of multiple double-headed drip irrigation components 205.

[0036] Below the drip irrigation diversion pipe 201, a drip irrigation head structure adjustment assembly 203 is provided. The drip irrigation head structure adjustment assembly 203 includes an adjusting screw 2034 and two fixed brackets 2031. A handle is fixedly connected to one end of the adjusting screw 2034, serving as a force application point for convenient control of the adjusting screw 2034. The adjusting screw 2034 is rotatably mounted on the two fixed brackets 2031 via two bearings. The adjusting screw 2034 is kept in stable rotation by the bearings, ensuring stable transmission between the adjusting screw 2034 and the adjusting nut 2032. This allows the adjusting nut 2032 to stably drive the movable bar 2036 and the indicator ring 2033. The adjusting screw 2034 is threadedly connected to the adjusting nut 2032. An adjusting seat 2035 is fixedly installed on the upper part of the drip irrigation system. An indicator ring 2033 and a movable strip 2036 are fixedly connected above the adjusting seat 2035. An observation port 2038 is provided above the indicator ring 2033. A drip irrigation diversion tube 201 is sleeved on the drip irrigation diversion tube 2051. Three indicator pieces 206 are provided on the drip irrigation diversion tube 2051. By corresponding the observation port 2038 with different indicator pieces 206, the switching state of the drip irrigation head structure 2051 can be quickly determined. When the observation port 2038 corresponds to the middle indicator piece 206, both drip irrigation head structures 2051 are in the open state. When the observation port 2038 is located at the positions of the left and right indicator pieces 206 respectively, the two drip irrigation head structures 2051 switch open, and the movable strip 2036 passes through. The movable strip 2036 is slidably oriented within multiple fixed pipe clamp structures 2021. Multiple guide grooves 2037 are provided above the movable strip 2036, allowing it to slide smoothly on the guide strip 2039 via the guide grooves 2037. This ensures stable transmission between the drive tooth segment 204 and the transmission gear 2052. The movable strip 2036 passes through the fixed pipe clamp structure 2021, guaranteeing stable support. The guide grooves 2037 and the guide strip 2039 are slidably connected. The guide strip 2039 is fixedly connected to the drip irrigation diversion pipe 201. Multiple drive tooth segments 204 are provided on the movable strip 2036 of the drip irrigation head structure adjustment assembly 203. These drive tooth segments 204 mesh with the transmission gear 2052 of the double-headed drip irrigation assembly 205. The movable bar 2036 controls the movement of multiple drive gear segments 204, enabling the drive gear segments 204 to transmit power to the transmission gear 2052. This allows for the adjustment of multiple dual-head drip irrigation components 205, improving the convenience and speed of operation. Each dual-head drip irrigation component 205 includes two drip head structures 2051, each containing a valve core structure 2053. The two valve core structures 2053 are configured to open and close in opposite directions. This opposite configuration allows the two valve core structures 2053 to rotate synchronously, switching between the two drip head structures 2051. A drive valve rod 2055 is located on one side of each valve core structure 2053. Both drive valve rods 2055 extend out of the drip head structure 2051 and connect to the same valve seat 2054.A transmission gear 2052 is fixedly mounted on the valve seat 2054, and two drip head unblocking components 207 are provided in the double-headed drip irrigation assembly 205.

[0037] In this embodiment: by setting two drip irrigation head structures 2051 at a single point, and by manually operating the adjusting screw 2034 and adjusting nut 2032 through threaded transmission, the adjusting nut 2032 drives the adjusting seat 2035 to move, causing the movable bar 2036 to drive the drive gear segment 204 to move. The drive gear segment 204 drives the transmission gear 2052, which drives the valve seat 2054 to rotate. The valve seat 2054 drives the drive valve stem 2055 to rotate, and the drive valve stem 2055 controls the movement of the valve core structure 2053. Thus, the opening and closing control of multiple drip irrigation head structures 2051 can be realized simultaneously. This not only enables simultaneous drip irrigation operation of two drip irrigation head structures 2051 at the same location, but also allows for flexible switching of the working states of the two drip irrigation head structures 2051, avoiding the problem of blockage of a single drip irrigation head structure 2051 affecting normal drip irrigation. Moreover, the entire operation is simple and convenient, ensuring the stable and efficient operation of the drip irrigation system, and enhancing the adaptability of the drip irrigation system to different planting environments and crop growth stages.

[0038] Example 2: Refer to Figure 7 and Figure 10A drip irrigation device for pomegranate tree planting includes a drip head unblocking assembly 207, which includes two fixing members 2071 fixedly connected to a drip head structure 2051. One end of each fixing member 2071 is fixedly connected to a fixing cavity 2074. The fixing cavity 2074 has an upper wide cavity 2079 and a lower narrow cavity 20710. The upper wide cavity 2079 has a wide opening, while the lower narrow cavity 20710... The narrow-mouth design enhances the pressure effect on the unblocking needle 2073, facilitating the unblocking of the drip inlet of the drip head structure 2051. The upper wide cavity 2079 and the lower narrow cavity 20710 are connected. An upper piston 2075 is installed in the upper wide cavity 2079. A return spring 2076 and a piston rod 2077 are fixedly connected above the upper piston 2075. After the drip head structure 2051 is opened by the valve core structure 2053, the return spring 2076 drives the upper piston 20710. 75 Reset, and then the lower piston 2072 can drive the unblocking needle 2073 to smoothly reset upward, which facilitates the automatic opening of the drip irrigation port of the drip irrigation head structure 2051 and facilitates drip irrigation operation. The top of the piston rod 2077 is provided with a ball structure 2078. The rolling nature of the ball structure 2078 can reduce the resistance between it and the valve core structure 2053, which facilitates the smooth control of the valve core structure 2053. The movement of the valve core structure 2053 causes the spherical surface of the valve core structure 2053 to press down on the ball structure 2078. The piston rod 2077 slides in the sealing sleeve 20711. The sealing sleeve 20711 is fixedly installed above the fixed cavity 2074. The sealing sleeve 20711 is fixedly connected to one end of the reset spring 2076. The lower piston 2072 is provided in the lower narrow cavity 20710. The unblocking needle 2073 is fixedly connected below the lower piston 2072 and passes through the fixed cavity 2074.

[0039] In this embodiment: By switching between the two drip head structures 2051, the valve core structure 2053 can drive the ball structure 2078 and piston rod 2077 to move. The upper piston 2075 uses air pressure to control the movement of the lower piston 2072, so that the unblocking needle 2073 can unclog the drip inlet of the drip head structure 2051, remove residual impurities in the drip inlet of the drip head structure 2051. When the drip head structure 2051 is idle, the unblocking needle 2073 can be inserted into the drip inlet to form a sealing structure, preventing impurities from entering the drip inlet and causing blockage. This design can solve the problem of easy clogging of the traditional drip head structure 2051 and the impact of clogging on normal operation, further reducing field operation and maintenance costs.

[0040] Example 3: Reference Figures 1-4 and Figure 7A drip irrigation device for pomegranate tree planting includes a diversion drip irrigation mechanism 200, which includes a drip irrigation diversion pipe 201 connected to the output port of a drip irrigation device 100. Multiple diversion pipe support assemblies 202 are provided on the drip irrigation diversion pipe 201. The drip irrigation diversion pipe 201 is connected to the drip head structure 2051 of multiple double-headed drip irrigation assemblies 205. A drip head structure adjustment assembly 203 is provided below the drip irrigation diversion pipe 201. Multiple drive tooth segments 204 are provided on the movable strip 2036 of the drip head structure adjustment assembly 203. The drive tooth segments 204 mesh with the transmission gear 2052 of the double-headed drip irrigation assembly 205. Two drip head unblocking assemblies 207 are provided in the double-headed drip irrigation assembly 205.

[0041] In this embodiment: the drip head structure adjustment component 203 can control the drive tooth segment 204 to adjust the dual-head drip irrigation component 205, so that the two drip head structures 2051 of the dual-head drip irrigation component 205 can switch operations. During the switching of the drip head structure 2051, the drip head unblocking component 207 can also be linked to unblock the drip inlet of the drip head structure 2051. No additional power source is required and no separate maintenance is required. The drip head unblocking component 207 ensures the unobstructed flow of the drip head structure 2051 and ensures the stable irrigation effect after the dual-point switching, avoiding the problem of insufficient water supply on one side due to the blockage of the drip inlet. Thus, the irrigation effect after switching is always stable and consistent. Through the coordinated cooperation of the dual-point switching irrigation and unblocking system, an integrated irrigation process of precise control, automatic cleaning and convenient operation and maintenance is realized.

[0042] Working principle: When drip irrigation is carried out on pomegranate trees, water is delivered through the drip irrigation device 100 and separated through the drip irrigation diversion pipe 201, so that the water is dripped onto the pomegranate trees through the drip irrigation head structure 2051.

[0043] When the two drip head structures 2051 are performing split drip irrigation, the adjusting screw 2034 is rotated by operating the handle. The adjusting screw 2034 drives the adjusting nut 2032 to move, the adjusting nut 2032 drives the adjusting seat 2035 to move, and the adjusting seat 2035 drives the indicator ring 2033 and the movable bar 2036 to move, so that the observation port 2038 corresponds to the middle indicator piece 206. The movement of the movable bar 2036 can drive the drive gear segment 204 to drive the transmission gear 2052. The transmission gear 2052 drives the valve seat 2054 to move, the valve seat 2054 drives the drive valve stem 2055 to rotate, and the drive valve stem 2055 drives the valve core structure 2053 to rotate, so that the two valve core structures 2053 keep the two drip head structures 2051 in a semi-open state, thereby enabling dual-point drip irrigation.

[0044] When switching between uses, the valve core structure 2053 continues to rotate, switching between opening the drip irrigation head structure 2051 for drip irrigation. The rotation of the valve core structure 2053 can also press down the ball bearing structure 2078 through the spherical surface. The ball bearing structure 2078 can drive the piston rod 2077 to move. The piston rod 2077 drives the upper piston 2075 to move. The upper piston 2075 uses air pressure to control the movement of the lower piston 2072. The lower piston 2072 controls the unblocking needle 2073 to unblock the drip irrigation head structure 2051 and close the drip irrigation port of the drip irrigation head structure 2051 after switching to prevent the drip irrigation port from being blocked.

[0045] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
