Description

Technical Field

[0001] This utility model belongs to the field of blueberry planting technology, specifically relating to a blueberry planting irrigation device. Background Technology

[0002] Blueberries are a fruit with high economic value, and irrigation is crucial in their cultivation. As a shallow-rooted plant, blueberries are sensitive to water and intolerant of waterlogging. During their growth, the soil around their roots must be kept moist but not waterlogged. Therefore, the evenness of irrigation and water control are essential.

[0003] Existing blueberry irrigation systems have the following problems in practical applications: traditional flood irrigation or fixed sprinkler irrigation methods are prone to uneven water distribution, with some planting areas becoming too wet and causing root rot, while other areas become too dry and affect growth; when multiple pipelines supply water at the same time, the water pressure is often unstable, resulting in large differences in the amount of water poured into different planting pots. Especially when planting on a large scale, the problem of insufficient water pressure in the distant pipelines is prominent, requiring water pumps with greater power and water output capacity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a blueberry planting irrigation device to address the issues in the prior art. The technical solution adopted by this utility model is as follows:

[0005] A blueberry irrigation device includes a water tank, irrigation pipes, planting pots, and an alternating irrigation mechanism. The water tank is connected to the alternating irrigation mechanism via an output pipe, and a water pump is installed on the output pipe. The alternating irrigation mechanism connects to multiple irrigation pipes, and multiple planting pots are arranged along the direction of the irrigation pipes. The irrigation pipes are connected to the planting pots via branch pipes. The alternating irrigation mechanism is used to sequentially and alternately supply water to the multiple irrigation pipes.

[0006] Furthermore, the alternating irrigation mechanism includes a motor, a housing, a rotating disk, and a central tube. The rotating disk is rotatably disposed within the housing, with an opening on its outer surface. The rotating disk has a vertical axis with a through hole along its axis, and a side hole communicating with the through hole is located at the inner end of the opening. The bottom of the central tube is disposed within the through hole and is fixedly connected to the rotating disk. The top of the central tube extends out of the housing, and a waist-shaped hole communicating with the side hole is located on the side of the central tube. The bottom of the through hole communicates with the output pipe. The motor is mounted on the top of the housing and is connected to the portion of the central tube extending out of the housing to drive the central tube to rotate, thereby rotating the rotating disk. Multiple irrigation pipes are connected to the side of the housing, with their connections distributed circumferentially around the housing. When the rotating disk rotates, the opening passes sequentially through the connections of the multiple irrigation pipes, and water is input into the central tube through the output pipe, passing sequentially through the waist-shaped hole, the side hole, and the opening before entering the irrigation pipe.

[0007] Furthermore, the outer side of the shell is surrounded by a plurality of water pipe connectors, which are connected to the interior of the shell. Each of the plurality of water pipe connectors is connected to a connecting pipe, and each of the connecting pipes is connected to the irrigation water pipe. When the rotating disk rotates, the opening passes through the plurality of water pipe connectors in sequence.

[0008] Furthermore, a sealing layer is provided on the outer side of the rotating disk and the inner side of the housing.

[0009] Furthermore, the output tube is detachably connected to the bottom of the housing, and the end of the output tube is inserted into the bottom of the through hole.

[0010] Furthermore, a pressure tube is fixedly connected to the top of the central tube. The pressure tube is sealed at the top and open at the bottom. The bottom opening of the pressure tube communicates with the top of the central tube. A piston is slidably disposed inside the pressure tube, and a spring is disposed above the piston. When the opening is covered by the inner wall of the housing, the piston rises.

[0011] Furthermore, a limiting block is fixedly connected inside the pressure tube, and the limiting block is located below the piston.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses the mechanical action of an alternating irrigation mechanism to control the water flow into different irrigation pipes sequentially, avoiding water pressure dispersion caused by multiple pipes supplying water simultaneously. It also allows water to gradually seep into the soil while waiting for the next irrigation after watering a row of planting pots. The intermittent irrigation method improves the soil's water absorption efficiency and prevents excessive water accumulation on the soil surface, which can lead to poor drainage and affect the respiration and growth of blueberry roots. Blueberries are sensitive to water, and by adjusting the water pump power and output volume during alternating irrigation, water can be precisely supplied according to the needs of plants in different areas, preventing waterlogging or water shortage.

[0018] The following will refer to the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0019] like Figures 1-3 A blueberry irrigation device includes a water tank 1, irrigation pipes 14, planting pots 15, and an alternating irrigation mechanism. The water tank 1 is connected to the alternating irrigation mechanism via an output pipe 3, and a water pump 2 is installed on the output pipe 3. The alternating irrigation mechanism connects to multiple irrigation pipes 14, and multiple planting pots 15 are arranged along the direction of the irrigation pipes 14. The irrigation pipes 14 are connected to the planting pots 15 via branch pipes. The alternating irrigation mechanism is used to sequentially and alternately supply water to the multiple irrigation pipes 14.

[0020] Multiple irrigation pipes 14 are arranged side by side, with a row of multiple planting pots 15 formed on each irrigation pipe 14. The planting pots 15 are used to grow blueberries. Branch pipes can be connected to the side openings of the irrigation pipes 14 through pipe connectors to achieve the purpose of water conduction. The branch pipes can be directly fixed to the top of the planting pots 15 to guide the water to the soil inside the planting pots 15.

[0021] In practice, water pump 2 is started, and water in water tank 1 is delivered to alternating irrigation mechanism through output pipe 3; alternating irrigation mechanism supplies water to different irrigation pipes 14 in sequence, and the water flows into the corresponding planting pot 15 through branch pipe to complete the irrigation of blueberry plants; the alternating water supply of multiple irrigation pipes 14 is achieved through repeated cycles.

[0022] This invention uses the mechanical action of an alternating irrigation mechanism to control the water flow to enter different irrigation pipes 14 sequentially, avoiding water pressure dispersion caused by multiple pipes supplying water simultaneously. It also allows water to gradually seep into the soil while waiting for the next irrigation after watering a row of planting pots 15. The intermittent irrigation method can improve the soil's water absorption efficiency and prevent excessive water accumulation on the soil surface, which would lead to poor drainage and affect the respiration and growth of blueberry roots. Blueberries are sensitive to water, and by adjusting the power and output of the water pump 2 during alternating irrigation, water can be precisely supplied according to the needs of plants in different areas, preventing water accumulation or water shortage.

[0023] It should be noted that the pressure and output water volume of the water pump 2 are sufficient to ensure that all the branch pipes on the irrigation pipe 14 can output water. Since the pressure is different at different locations inside the irrigation pipe 14, in order to balance the output water volume, the branch pipes on the irrigation pipe 14 should be designed with gradually increasing inner diameters, that is, the inner diameter of the branch pipes gradually increases in the direction away from the water pump 2, so as to balance the pressure changes inside the irrigation pipe 14 and output similar water volumes.

[0024] Furthermore, the alternating irrigation mechanism includes a motor 4, a housing 5, a rotating disk 6, and a central tube 11; the rotating disk 6 is rotatably disposed inside the housing 5, and an opening 602 is provided on the outer side of the rotating disk 6. The axis of the rotating disk 6 is vertically arranged, and a through hole is provided on its axis. A side hole 601 communicating with the through hole is provided at the inner end of the opening 602; the bottom of the central tube 11 is disposed in the through hole, the central tube 11 is fixedly connected to the rotating disk 6, the top of the central tube 11 extends out of the housing 5, and an oblong hole 111 communicating with the side hole 601 is provided on the side of the central tube 11; The bottom of the through hole is connected to the output pipe 3; the motor 4 is installed on the top of the housing 5, and the motor 4 is connected to the part of the central pipe 11 that extends out of the housing 5 to drive the central pipe 11 to rotate, so that the rotating disk 6 rotates; the side of the housing 5 is connected to a plurality of irrigation water pipes 14, and their connection points are distributed around the circumference of the housing 5; when the rotating disk 6 rotates, the opening 602 passes through the connection points of the plurality of irrigation water pipes 14 in sequence, the output pipe 3 inputs water into the central pipe 11, and then passes through the waist-shaped hole 111, the side hole 601 and the opening 602 in sequence before entering the irrigation water pipe 14.

[0025] When motor 4 starts, it drives the central tube 11 to rotate, which in turn drives the rotating disk 6 to rotate synchronously within the housing 5. Water from the output pipe 3 enters the central tube 11, flows through the oblong hole 111 into the side hole 601, and then into the opening 602. As the rotating disk 6 rotates, the opening 602 sequentially aligns with the connection points (pipe connectors 12) between the side of the housing 5 and the irrigation pipe 14, allowing water to flow into the corresponding irrigation pipe 14. The rotating disk continues to rotate, achieving alternating water supply to each irrigation pipe. Motor 4 provides rotational power, which is transmitted to the rotating disk 6 through the central tube 11, causing the opening 602 to periodically align with the connection points on the side of the housing. The oblong hole 111, the side hole 601, and the opening 602 remain connected during rotation. The mechanical rotation achieves the switching of water flow and controls the water supply sequence. The rotating disk 6 should rotate slowly, for example, one revolution every 1 to 5 minutes.

[0026] In addition, the internal size of the housing 5 is adapted to the rotating disk 6, and it is a cylindrical inner cavity. The top opening of the housing 5 can be connected to the cover plate by bolts. The motor 4 is mounted on the cover plate. The motor 4 can be connected to the upper end of the central tube 11 through a gear set, a synchronous belt and a pulley. Preferably, a synchronous belt and a pulley are used, that is, a synchronous pulley is fitted on the central tube 11. The output end of the motor 4 is fixedly connected to the drive wheel. A synchronous belt is fitted on the synchronous pulley and the drive wheel, thereby realizing the function of power transmission.

[0027] Furthermore, a plurality of water pipe connectors 12 are arranged around the outer side of the housing 5. The water pipe connectors 12 are connected to the interior of the housing 5. Each of the plurality of water pipe connectors 12 is connected to a connecting pipe 13, and each of the plurality of connecting pipes 13 is connected to the irrigation water pipe 14. When the rotating disk 6 rotates, the opening 602 passes through the plurality of water pipe connectors 12 in sequence.

[0028] When the rotating disk 6 rotates, the opening 602 aligns sequentially with each water pipe connector 12, and water flows from the opening 602 into the water pipe connector 12, then through the connecting pipe 13 to the corresponding irrigation pipe 14. When misaligned, the water pipe connector 12 is sealed by the outer surface of the rotating disk 6, and no water flows in. The water pipe connector 12 serves as a transition interface between the housing 5 and the connecting pipe 13, and its circumferential distribution matches the opening 602, achieving periodic connection through rotation. The connecting pipe 13 extends the water supply path, adapting to the distribution position of different planting pots.

[0029] Furthermore, a sealing layer is provided on the outer surface of the rotating disk 6 and the inner surface of the housing 5. The sealing layer is a prior art material, such as a rubber sealing ring, an elastic sealing gasket, or a sealing coating. When the rotating disk 6 rotates within the housing 5, the sealing layers of both surfaces fit tightly together, preventing water leakage from the gap between the rotating disk 6 and the inner wall of the housing 5. Water can only flow out through the alignment of the opening 602 and the water pipe connector 12.

[0030] Furthermore, the output tube 3 is detachably connected to the bottom of the housing 5, and the end of the output tube 3 is inserted into the bottom of the through hole.

[0031] Specifically, a flange 301 can be installed on the output pipe 3. The flange 301 is bolted to the bottom of the housing 5, and the end of the output pipe 3 is inserted into the through hole. A corresponding sealing device can be installed between the flange 301 and the bottom of the housing 5.

[0032] Furthermore, a pressure tube 7 is fixedly connected to the top of the central tube 11. The pressure tube 7 is sealed at the top and open at the bottom. The bottom opening of the pressure tube 7 communicates with the top of the central tube 11. A piston 9 is slidably disposed inside the pressure tube 7, and a spring 8 is disposed above the piston 9. When the opening 602 is covered by the inner wall of the housing 5, the piston 9 rises.

[0033] Furthermore, a limiting block 10 is fixedly connected inside the pressure tube 7, and the limiting block 10 is located below the piston 9.

[0034] When the opening 602 of the rotating disk 6 is covered by the inner wall of the housing 5, the water in the central pipe 11 cannot flow out, and the water pressure increases, pushing the piston 9 to rise in the pressure pipe 7, compressing the spring 8. When the opening 602 is aligned with the water pipe connector 12, the water pressure decreases, the spring 8 returns to its original position, pushing the piston 9 down, pushing the water in the pressure pipe 7 back into the central pipe 11 and finally outputting through the irrigation pipe 14. The piston 9 and the spring 8 form a pressure buffer structure. When the water flow channel is closed, the water pressure is converted into the elastic potential energy of the spring 8 and stored. When the channel is open, the elastic potential energy is released to drive the water flow, avoiding the impact of a sudden increase in water pressure on the system. The design of the pressure pipe 7 can buffer pressure fluctuations, protect the water pump 2 and pipeline from water hammer damage, and ensure a stable water flow output when the opening 602 is open. The limiting block 10 acts as a limit, and under the elastic force of the spring 8, the piston 9 abuts against the limiting block 10.

[0035] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
