Description

TECHNICAL FIELD

[0001] The application relates to the technical field of irrigation devices, in particular to a water-saving irrigation device for garden maintenance. BACKGROUND

[0002] In the field of garden maintenance, irrigation is a key link to ensure the healthy growth of plants. Traditional irrigation methods such as surface sprinkling and flooding have the problem of serious water waste. Because most of the water is retained on the soil surface, it is easy to be lost through evaporation and runoff, and it is difficult to penetrate into the plant root system, resulting in low water utilization rate. In addition, for plants that need to be irrigated with water and fertilizer integrated irrigation liquid, i.e. liquid containing solid fertilizers or agents, surface irrigation may also cause nutrient volatilization or loss, and cannot achieve precise fertilization.

[0003] To save water resources, water-saving technologies such as drip irrigation and infiltration irrigation are widely used. These technologies can directly deliver water to the vicinity of plant roots. However, many existing underground irrigation devices are fixed and pre-embedded, which have the problems of complicated operation, high labor intensity and inability to adapt to the dynamic growth of roots. In addition, a key difficulty in achieving efficient root irrigation is how to uniformly supply water within the vertical depth of root distribution. Conventional pre-embedded point irrigation may not fully consider roots at different depths. In addition, when the irrigation liquid contains solid components such as fertilizers and organic matter that have not completely dissolved, sedimentation and hardening may occur in the liquid storage device, which not only affects the uniformity of the irrigation liquid, but also easily causes blockage when delivered to the water outlet, seriously affecting the reliability and sustainability of the irrigation system. In addition, traditional stirring devices often need independent driving sources, which increases the complexity and energy consumption of the equipment.

[0004] Therefore, there is an urgent need in the art for an integrated solution that can achieve efficient water saving and precise irrigation while effectively preventing irrigation liquid blockage.

[0033] 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.

[0034] Please see Figures 1-10 As an embodiment of the present invention, a water-saving irrigation device for garden greening maintenance includes a main frame 1, a liquid storage tank 2 fixed on the main frame 1, a drive cylinder 4 fixed on the main frame 1, a first piston rod 5 installed at the output end of the drive cylinder 4, a crossbeam 6 fixed on the first piston rod 5, a water supply pipe 7 fixed on the crossbeam 6, and a water outlet hole 8 opened at the bottom end of the water supply pipe 7.

[0035] A water pumping mechanism is provided on the main frame 1. When the first piston rod 5 rises, the water pumping mechanism draws water from the inside of the storage tank 2. When the first piston rod 5 falls to a certain height, the water pumping mechanism delivers the drawn water to the inside of the water supply pipe 7.

[0036] The storage tank 2 is equipped with a stirring mechanism, which includes a stirring shaft 25 rotatably installed in the storage tank 2. A stirring blade 26 is fixed on the stirring shaft 25. The stirring shaft 25 and the first piston rod 5 are connected by a first linkage structure. When the first piston rod 5 moves up and down, it will drive the stirring shaft 25 to rotate back and forth.

[0037] In this embodiment, a guide cylinder 24 is fixed on the main frame 1, and the water supply pipe 7 is inserted through the guide cylinder 24. The guide cylinder 24 limits the vertical movement of the water supply pipe 7. In use, the drive cylinder 4 is activated to drive the first piston rod 5 to rise and fall, which in turn drives the crossbeam 6 to rise and fall, thereby driving the water supply pipe 7 to rise and fall. By controlling the rise and fall of the water supply pipe 7, it actively extends downward into the soil. During this movement, when the first piston rod 5 rises, the pumping mechanism draws water from the storage tank 2. When the first piston rod 5 falls to a certain height, that is, when it is near the soil near the plant roots, the pumping mechanism delivers the drawn water to the water supply pipe 7 and irrigates the plant roots through the water outlet 8. In addition, when the first piston rod 5 moves up and down, it drives the stirring shaft 25 to rotate back and forth. As long as the first piston rod 5 moves up and down, the rotation of the stirring shaft 25 will drive the stirring blades 26 to rotate and stir the inside of the storage tank 2. This can effectively prevent the solid components in the water-fertilizer mixture in the storage tank 2 from settling and caking, and fundamentally avoid the risk of the water outlet 8 being blocked at critical irrigation times.

[0038] As a further embodiment of the present invention, a feeding hopper 3 that communicates with the interior of the liquid storage tank 2 is fixed on the main frame 1. The feeding hopper 3 is used to convey solid materials and liquid water into the liquid storage tank 2.

[0039] In this embodiment, by setting up the feed hopper 3, irrigation water and solid or liquid fertilizers, pesticides, etc. can be easily added to the storage tank 2, which facilitates the preparation of integrated water and fertilizer irrigation solution to meet the growth needs of plants.

[0040] As a further embodiment of the present invention, the pumping mechanism includes a pump body 9 fixed on the main frame 1. A second piston rod 11 is movably inserted into the pump body 9. A piston 10 is fixed on the second piston rod 11 and movably engaged inside the pump body 9. An inner movable rod 12 fixed to the crossbeam 6 is movably inserted into the second piston rod 11. A locking block 13 is fixed on the inner movable rod 12 and movably engaged inside the second piston rod 11. A spring 14 connects the locking block 13 and the piston 10. An inlet pipe 15 communicating with the storage tank 2 and an outlet pipe 16 communicating with the water supply pipe 7 are fixed on the pump body 9. A one-way valve is installed on the inlet pipe 15, and an adjustable valve is provided on the outlet pipe 16. The adjustable valve and the crossbeam 6 cooperate through a second linkage structure. When the crossbeam 6 rises, the one-way valve opens and the adjustable valve closes, and the liquid inside the storage tank 2 is drawn into the pump body 9. When the crossbeam 6 descends to a certain height, the one-way valve closes and the adjustable valve opens, and the liquid inside the pump body 9 is transported into the water supply pipe 7.

[0041] In this embodiment, when the drive cylinder 4 drives the first piston rod 5 to rise, causing the crossbeam 6 to rise, the crossbeam 6, through the inner movable rod 12, overcomes the elastic force of the spring 14 and first pulls the locking block 13 to the inner top wall of the second piston rod 11. Then, the inner movable rod 12 continues to move upward, causing the piston 10 at the end of the second piston rod 11 to move upward inside the pump body 9. At this time, a negative pressure is formed inside the pump body 9, the one-way valve on the inlet pipe 15 opens, and the adjustable valve on the outlet pipe 16 is closed under the action of the second linkage structure. The irrigation liquid in the storage tank 2 is sucked into the pump body 9 to complete the storage. When the drive cylinder 4 drives the first piston rod 5 to fall, causing the crossbeam 6 and the water pipe 7 to move downward, in the initial stage, due to the pressure inside the pump body 9, When the crossbeam 6 moves downward, it drives the inner movable rod 12 and the locking block 13 to move downward, pushing the spring 14 to compress. The piston 10 is initially stationary. Then, the locking block 13 continues to move downward, and the spring 14 continues to compress, pushing the piston 10 downward. When the crossbeam 6 descends to a specific height, i.e., when the water pipe 7 reaches the predetermined irrigation depth, the second linkage structure is activated, triggering the adjustable valve to open, while the one-way valve of the inlet pipe 15 closes. The crossbeam 6 continues to descend, pushing the second piston rod 11 and the piston 10 downward as a whole through the inner movable rod 12, pressing the irrigation liquid stored in the pump body 9 into the water pipe 7 through the outlet pipe 16 and the opened adjustable valve, thus achieving precise irrigation. This design realizes automatic linkage between pumping and irrigation, which is energy-saving and efficient.

[0042] As a further embodiment of the present invention, the adjustable valve includes a ball valve body 17 fixed on the main frame 1. The ball valve body 17 is installed in the passage of the liquid outlet pipe 16 and communicates with the liquid outlet pipe 16. A valve core shaft 18 is rotatably mounted on the ball valve body 17. One end of the valve core shaft 18 is rotatably connected to the crossbeam 6. A valve core 19 is fixed on the valve core shaft 18 and is movably engaged inside the ball valve body 17. An overflow hole 20 is provided on the valve core 19.

[0043] In this embodiment, the adjustable valve is controlled by the rotation of the valve core 19. When the valve core shaft 18 drives the valve core 19 to rotate, so that the flow hole 20 on the valve core 19 is aligned with the flow channel of the ball valve body 17, the valve opens and liquid can pass through. When the valve core 19 rotates through a certain angle and its solid part blocks the flow channel, the valve closes. The rotation of the valve core shaft 18 is controlled by the lifting and lowering of the crossbeam 6 through the second linkage structure.

[0044] As a further embodiment of the present invention, the second linkage structure includes a guide ring 21 fixedly connected to the crossbeam 6 and a special channel 22 opened on the valve core shaft 18. The inner wall of the guide ring 21 is movably embedded and engaged with a first ball 23. The first ball 23 is movably engaged in the special channel 22 and can roll in the channel where the special channel 22 is located. The special channel 22 includes a straight channel, an arc channel and a straight channel connected sequentially from top to bottom. When the crossbeam 6 moves up and down, it can drive the valve core shaft 18 to rotate counterclockwise and clockwise.

[0045] In this embodiment, when the crossbeam 6 rises and falls, it drives the guide ring 21 to move synchronously. The first ball 23 inside the guide ring 21 rolls along the special groove 22 on the valve core shaft 18. When the crossbeam 6 rises, the first ball 23 first passes through the arc section of the special groove 22, driving the valve core shaft 18 to rotate and rotate the valve core 19 to the position where the ball valve body 17 closes the flow channel. Then, when it continues to rise, the guide ring 21 passes through the upper straight groove section of the special groove 22, and the valve core shaft 18 is still in the position where the valve core 19 closes the flow channel. When the crossbeam 6 falls, the guide ring 21 first passes through the straight groove section of the special groove 22. After passing through the arc section of the special channel 22, the first ball bearing 23 enters the arc transition section of the special channel 22, forcing the valve core shaft 18 to rotate, thereby driving the valve core 19 to rotate until the flow hole 20 is aligned with the flow channel, and the ball valve body 17 opens. When the crossbeam 6 continues to move down, the guide ring 21 passes through the lower straight groove section of the special channel 22, and the valve core 19 does not rotate, so the ball valve body 17 remains open. The water pipe 7 also reaches the area near the plant roots. At the same time, the water inside the pump body 9 can also enter the water pipe 7 through the liquid outlet pipe 16 and irrigate the plant roots through the water outlet hole 8. As the crossbeam 6 rises again, the guide ring 21 passes through the lower straight section of the special channel 22, and the valve core 19 does not rotate, so the ball valve body 17 remains open. The locking block 13 also moves upwards simultaneously, and the spring 14 elastically resets. At this stage, the locking block 13 has not yet reached the inner top wall of the second piston rod 11, so the second piston rod 11 will not pull the piston 10 upwards. That is, at this time, a negative pressure will not be formed inside the pump body 9 to draw water from the storage tank 2 or to back-suction water from the outlet pipe 16. When the crossbeam 6 continues to move upwards, the guide ring 21 passes through the arc section of the special channel 22 again, and the valve core shaft 18 rotates. The valve core 19 is rotated until the flow hole 20 is aligned with the flow channel, and the ball valve body 17 is closed. At this time, the locking block 13 reaches the inner top wall of the second piston rod 11. Then the crossbeam 6 continues to move upward, and the guide ring 21 passes through the upper straight groove section of the special channel 22. The valve core 19 does not rotate, so the ball valve body 17 is still in the closed state. At the same time, the locking block 13 on the other side moves upward, pulling the second piston rod 11 upward, which in turn moves the piston 10 upward, so that a negative pressure is formed inside the pump body 9. In conjunction with the liquid inlet pipe 15, the irrigation liquid inside the liquid storage tank 2 is drawn into the pump body 9. This cycle achieves the purpose of repeated water intake and repeated irrigation.

[0046] As a further embodiment of the present invention, the water supply pipe 7 and the inner movable rod 12 are respectively installed through the frame of the main body frame 1.

[0047] In this embodiment, the main frame 1 limits the lifting and lowering of the water pipe 7 and the inner movable rod 12, making the lifting and lowering movements of the water pipe 7 and the inner movable rod 12 more stable and preventing positional deviation during vertical movement.

[0048] As a further embodiment of the present invention, the first linkage structure includes a transmission shaft sleeve 27 rotatably mounted on the main frame 1. The first piston rod 5 and the transmission shaft sleeve 27 are engaged through a rolling groove structure. When the first piston rod 5 moves up and down, it will drive the transmission shaft sleeve 27 to rotate. The transmission shaft sleeve 27 and the stirring shaft 25 are engaged through a gear mechanism. When the transmission shaft sleeve 27 rotates, it will drive the stirring shaft 25 to rotate.

[0049] In this embodiment, the up-and-down movement of the first piston rod 5 drives the transmission shaft sleeve 27 to reciprocate through the groove structure, and then transmits the motion to the stirring shaft 25 through the gear mechanism to drive the stirring shaft 25 to rotate. When the stirring shaft 25 rotates, it drives the stirring blade 26 to rotate to achieve the stirring function inside the liquid storage tank 2.

[0050] As a further embodiment of the present invention, the grooving structure includes a spiral groove 28 formed on the first piston rod 5 and a second ball 29 movably embedded and engaged in the inner wall of the transmission shaft sleeve 27. The second ball 29 is movably engaged in the spiral groove 28 and can roll within the groove where the spiral groove 28 is located.

[0051] In this embodiment, when the first piston rod 5 moves up and down, it drives the spiral groove 28 to move up and down. Since the second ball 29 is movably engaged inside the spiral groove 28, the transmission shaft sleeve 27 is restricted to only rotate. The second ball 29 is pushed by the groove wall of the spiral groove 28, which causes the transmission shaft sleeve 27 to rotate. The continuous reciprocating motion of the first piston rod 5 is converted into the reciprocating rotation of the transmission shaft sleeve 27 through the groove engagement.

[0052] As a further embodiment of the present invention, the gear mechanism includes a driving gear 30 fixed on the transmission shaft sleeve 27 and a driven gear 31 fixed on the stirring shaft 25, wherein the driving gear 30 meshes with the driven gear 31.

[0053] In this embodiment, when the transmission shaft sleeve 27 rotates, it drives the drive gear 30 to rotate. The drive gear 30 meshes with the driven gear 31 to drive the driven gear 31 to rotate. When the driven gear 31 rotates, it drives the stirring shaft 25 to rotate.

[0054] The working principle of this invention is as follows: The drive cylinder 4 is activated, driving the first piston rod 5 to reciprocate upward and downward. When the first piston rod 5 rises, it drives the second piston rod 11 of the pumping mechanism upward through the crossbeam 6 and the inner movable rod 12, drawing irrigation liquid from the storage tank 2 into the pump body 9 for storage. Simultaneously, the second linkage structure keeps the adjustable valve closed. When the first piston rod 5 descends, it first drives the water delivery pipe 7 downward into the soil. When it reaches the predetermined irrigation depth, the second linkage structure activates, opening the adjustable valve. At the same time, the pumping mechanism, under the action of the piston 10, pumps the irrigation liquid stored in the pump body 9 into the water delivery pipe 7, which flows out from the outlet hole 8 for root irrigation. During the entire lifting and lowering process, the movement of the first piston rod 5 also drives the stirring shaft 25 and stirring blades 26 to reciprocate through the first linkage structure, continuously stirring the irrigation liquid in the storage tank 2 to prevent sedimentation and caking, ensuring smooth irrigation. The entire device uses only one power source, efficiently and in a coordinated manner completing the three major functions of deep irrigation, quantitative liquid supply, and anti-clogging stirring, resulting in significant water-saving effects and high reliability.

[0055] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
