Description

Technical Field

[0001] The invention relates to the technical field of plant sprinkler irrigation, and in particular to light-sensitive garden plant sprinkler irrigation equipment. Background Art

[0002] In order to ensure the normal growth of plants, sufficient water must be supplied. Under natural conditions, the water requirements of plants cannot be met due to insufficient or uneven precipitation. Therefore, artificial irrigation must be carried out to make up for the lack of natural rainfall. The irrigation principle is that the amount of irrigation, the number of irrigations and the time of irrigation should be determined according to the water requirements of plants, the growth stage, the climate and the soil conditions. It is necessary to irrigate at the right time, in the right amount and reasonably.

[0003] Current irrigation equipment is generally a water pipe pre-buried in the soil or placed between plants, with irrigation joints installed on the water pipe. The irrigation of plants mainly relies on the subjective judgment of the staff, and cannot achieve accurate quantified watering, resulting in irrigation often being carried out when it is not needed. The amount of irrigation water is also difficult to accurately control, and the irrigation spray volume cannot be adjusted according to the intensity of light. Even when the light intensity is weak, the irrigation spray volume is still fixed, which not only wastes water resources, but also excessive or insufficient irrigation is not conducive to plant growth. For this reason, the present application proposes a light-sensing garden plant sprinkler irrigation equipment that can save water. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The atomized water spray irrigation of the present application is suitable for some precious plant varieties, and of course it can also take into account the irrigation of plants with a slightly larger area. It has a wide range of applications. During specific operation, the fast-flowing irrigation water can drive the spiral blades and the transmission rod to rotate when passing through the third short tube. The rotation of the transmission rod drives the diverter box to rotate. The rotation of the diverter box causes the arc block to drive the short rod to rotate due to centrifugal force. The rotation of the arc block causes the atomizing nozzle to be located outside the U-shaped block. The clean water in the diverter box is transported to the unfolded atomizing nozzle through the pumping pipe, and finally sprayed out through the atomizing nozzle to achieve irrigation of the plants.

[0016] 2. Since the diversion box is driven to rotate, multiple atomizing nozzles can be rotated, so that the plants can be sprayed more evenly to ensure the quality of irrigation and avoid wasting water resources by irrigating the same position multiple times.

[0017] 3. The rotation of the diversion box drives the atomizing nozzle to rotate and move up and down, which can irrigate plants in multiple ranges, saving the installation of traditional nozzles and saving water resources.

[0018] 4. The rotation of the short rod drives the connecting piece and the arc piece to rotate, so the multiple arc pieces no longer block the light-sensitive receiver. The centrifugal force can be used to throw out the debris on the arc piece to avoid blocking the light-sensitive receiver and affecting its receiving signal.

[0019] 5. When the rectangular piston moves upward, the water in the water storage cylinder can be sucked into the rotating piston cylinder through the first short tube. At this time, the water pressure in the water storage cylinder is reduced, thereby causing the water pressure at the atomizing nozzle to decrease, reducing the spraying amount of the atomizing nozzle. When the rectangular piston moves downward, the clean water in the rotating piston cylinder can be discharged through the first short tube, thereby increasing the water pressure in the water storage cylinder, further increasing the water pressure at the atomizing nozzle, and increasing the spraying amount of the atomizing nozzle. In this way, the spraying range is intermittently reduced and increased in a spiral shape, further ensuring uniform spraying of the plants.

[0020] 6. When the rectangular piston moves upward, the water in the water supply cylinder can be sucked into the rotating piston cylinder through the vertical pipe. When the rectangular piston moves downward, the water in the rotating piston cylinder can be discharged into the water storage cylinder through the second short pipe. This can increase the water pressure in the water storage cylinder, thereby increasing the water pressure at the atomizing nozzle, increasing the spraying volume and spraying range at the atomizing nozzle, and thus more effectively and evenly irrigating the plants.

[0021] 7. The shunt box is located in the receiving ring, which can protect the shunt box. The short rod is reset under the action of the torsion spring, and the arc-shaped piece is reset to cover and protect the light-sensitive receiver, making it less susceptible to the external environment.

[0022] 8. The arc block is reset so that the atomizing nozzle can be stored in the U-shaped block. The U-shaped block can shield the atomizing nozzle to prevent it from being blocked by falling debris.

[0023] To sum up, the present invention utilizes the existing light sensing probe to control the operation of the motor and water pump, etc., can adaptively irrigate the plants, can save water resources, and at the same time, can increase the spraying amount and spraying range at the atomizing nozzle, thereby more effectively and evenly irrigating the plants.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The technical solution further optimized in this embodiment is that the upper end of the reciprocating screw 18 is rotatably connected to a connecting rod 21, the upper end of the connecting rod 21 is fixedly connected to a short plate 25, the upper end of the short plate 25 is fixedly connected to two pull rods 26, the pull rods 26 are fixedly connected to the lifting piston 28, a vertical plate 6 is installed on the support plate 4, a motor 7 is installed on the vertical plate 6, the output end of the motor 7 is fixedly connected to a driving rod 11, the driving rod 11 passes through the water storage cylinder 5 and is rotatably connected thereto, a first bevel gear 19 is installed on the driving rod 11, a second bevel gear 20 is installed on the rotating piston cylinder 12, and the first bevel gear 19 is meshed with the second bevel gear 20.

[0040] A water supply pipe 27 is fixedly connected to the lifting piston 28. The water supply pipe 27 passes through the upper end of the water supply piston cylinder 2 and is slidably connected thereto. A through groove is penetrated through the upper end of the water supply piston cylinder 2. The water supply pipe 27 passes through the through groove. An opening can be opened at the upper end of the water supply piston cylinder 2 to facilitate air flow between the water supply piston cylinder 2 and the lifting piston 28.

[0041] The upper end of the water supply pipe 27 is rotatably connected to a diversion box 30 connected thereto, and a receiving ring 3 is fixed to the upper end of the water supply piston cylinder 2. A drainage hole 22 is penetrated through the receiving ring 3, and a movable ring 29 fixed on the water supply pipe 27 and located below the diversion box 30 slides inside the receiving ring 3. The upward movement of the movable ring 29 can push out the soil or weeds in the receiving ring 3; during installation, the water supply cylinder 1 is installed in the soil (plant growth area), and the upper end of the receiving ring 3 can be flush with the soil or slightly higher than the soil, so that the present invention can be hidden. When pedestrians want to take pictures of plants, there will be no vertical water pipes and nozzles set in the prior art, resulting in unsatisfactory shooting effects and inconvenience for pedestrians to take pictures. The invention can also be hidden in a bush of plants similar to evergreens.

[0042] The outer wall of the diverter box 30 is rotatably mounted with a plurality of short rods 42 that can be reset. The outer wall of the diverter box 30 is fixedly connected to two fixed blocks 35. The short rods 42 penetrate the two fixed blocks 35 and are rotatably connected thereto. A torsion spring is mounted between the short rods 42 and the fixed blocks 35, and the short rods 42 can be reset by the torsion spring.

[0043] An arc block 36 is fixedly connected to the short rod 42, and the short rod 42 is located on one side of the arc block 36. A fixedly connected pumping pipe 37 runs through the arc block 36, and the pumping pipe 37 is connected to the diverter box 30. A hose is fixedly connected to the pumping pipe 37, and the hose is connected to the diverter box 30; an atomizing nozzle 38 is installed at the other end of the pumping pipe 37, and a U-shaped block 34 is fixed to the outer wall of the diverter box 30, and the atomizing nozzle 38 is accommodated in the U-shaped block 34. The diverter box 30 rotates, and the centrifugal force is used to rotate the arc block 36 and drive the atomizing nozzle 38 away from the diverter box 30, and the plants are irrigated by the unfolded atomizing nozzle 38. A light-sensing receiver 31 is installed at the upper end of the diverter box 30, and the light-sensing receiver 31 can receive signals to control the spray amount of the atomizing nozzle 38.

[0044] It is worth noting that the water spray components of the present application do not need to all be atomizing nozzles 38, but can also be other ordinary nozzles. The corresponding nozzles are controlled by solenoid valves. The light-sensing receiver 31 and the solenoid valve are remotely controlled through electromagnetic signal or network signal transmission or connected to a mobile phone APP, so as to achieve regulation of plant irrigation water demand.

[0045] Among them, the photosensitive receiver 31 is explained: the photosensitive receiver 31 is connected to an external photosensitive probe, which can detect the light intensity and record the lighting duration, and then control the switch of the motor 7, the solenoid valve 14, and the electronic one-way control valve 15. The control system of the photosensitive probe can refer to the prior art CN109329008A.

[0046] The technical solution further optimized in this embodiment also includes a supply mechanism connected to the light-sensitive receiver 31 to increase the spray volume of the atomizing nozzle 38. The supply mechanism includes a vertical pipe 8 fixed to the bottom of the rotating piston cylinder 12. The vertical pipe 8 penetrates the water storage cylinder 5 and the support plate 4 and is rotatably connected thereto. A one-way valve 9 is installed at the bottom of the vertical pipe 8. The one-way valve 9 only allows water to flow through the vertical pipe 8 into the rotating piston cylinder 12. A first short tube 13 and a second short tube 24 are installed on the rotating piston cylinder 12. A solenoid valve 14 is installed on the first short tube 13, and an electronic one-way control valve 15 is installed on the second short tube 24. The motor 7, the solenoid valve 14, and the electronic one-way control valve 15 are all connected to the light-sensitive receiver 31. The light-sensitive receiver 31 is connected to a controller, and the controller controls the switching of the motor 7, the solenoid valve 14, the electronic one-way control valve 15, and the water pump 43; the electronic one-way control valve 15 is composed of the solenoid valve 14 and a one-way valve body, and the one-way valve body only allows water to flow through the rotating piston cylinder 12 into the second short tube 24.

[0047] The technical solution further optimized in this embodiment also includes a pumping mechanism for conveying clean water into the water storage cylinder 5. The pumping mechanism includes a water pump 43 installed on the support plate 4. The water pump 43 is also controlled by the light-sensitive receiver 31. The water inlet end and the water outlet end of the water pump 43 are respectively installed with an inlet pipe 10 and an outlet pipe 44. The inlet pipe 10 is arranged through the support plate 4, and the outlet pipe 44 is connected to the water storage cylinder 5.

[0048] The technical solution further optimized in this embodiment also includes a water flow driving mechanism for driving the diverter box 30 to rotate, the water flow driving mechanism includes a third short tube 23 that passes through the diverter box 30 and the water supply pipe 27, the third short tube 23 is fixedly connected to the water supply pipe 27, the third short tube 23 is rotatably connected to the diverter box 30, a support block 39 is fixed to the bottom of the third short tube 23, a rotatably arranged transmission rod 40 passes through the support block 39, a plurality of spiral leaves 41 are fixed to the transmission rod 40, and the upper end of the transmission rod 40 is fixedly connected to the diverter box 30.

[0049] The technical solution further optimized in this embodiment also includes a protection mechanism for protecting the light-sensing receiver 31 , the protection mechanism includes a connecting plate 33 fixed to the upper end of the short rod 42 , a plurality of arc-shaped plates 32 are fixed on the connecting plate 33 , the plurality of arc-shaped plates 32 are offset to form a full circle and cover the upper end of the light-sensing receiver 31 .

[0050] When the present invention is used, when the light sensor receiver 31 receives a signal that the plant needs to be irrigated (through the light intensity numerical parameter, and the soil moisture sensor parameter is assisted to determine whether to irrigate, and when the soil moisture sensor detects that the relative moisture content of the soil is lower than 65% and / or the light intensity is higher than the set value, irrigation is performed), the controller controls the motor 7, the solenoid valve 14, and the water pump 43 to be energized, and the solenoid valve 14 is opened;

[0051] The motor 7 drives the driving rod 11 to rotate, and the driving rod 11 rotates to drive the first bevel gear 19 to rotate, and the first bevel gear 19 rotates to drive the second bevel gear 20 to rotate, thereby realizing the rotation of the rotating piston cylinder 12, and the rotation of the rotating piston cylinder 12 drives the rectangular piston 16 to rotate, thereby driving the reciprocating screw 18 to rotate, and the reciprocating screw 18 rotates and reciprocates up and down on the fixed plate 17, and the reciprocating screw 18 reciprocates up and down, drives the connecting rod 21, the short plate 25 and the pull rod 26 to reciprocate up and down, and then drives the lifting piston 28 and the water delivery pipe 27 to reciprocate up and down, and the water delivery pipe 27 moves upward to drive the movable ring 29 and the diverter box 30 to move upward and extend out of the receiving ring 3, and the movable ring 29 moves upward to push out the debris that falls into the receiving ring 3, so as to realize the cleaning of the receiving ring 3;

[0052] The water pump 43 can deliver the water in the water supply cylinder 1 to the water storage cylinder 5 through the water inlet pipe 10 and the solenoid valve 14. As the amount of water in the water storage cylinder 5 increases, the clean water is delivered to the diverter box 30 through the water delivery piston cylinder 2, the water delivery pipe 27 and the third short pipe 23. The fast-flowing clean water can drive the spiral blade 41 and the transmission rod 40 to rotate when passing through the third short pipe 23. The rotation of the transmission rod 40 drives the diverter box 30 to rotate. The rotation of the diverter box 30 causes the arc block 36 to drive the short rod 42 to rotate due to centrifugal force. The rotation of the arc block 36 causes the atomizing nozzle 38 to be located outside the U-shaped block 34. The clean water in the diverter box 30 is delivered to the expanded atomizing nozzle 38 through the pumping pipe 37. Finally, the atomizing nozzle 38 sprays out to irrigate the plants.

[0053] Since the diverter box 30 is driven to rotate, the multiple atomizing nozzles 38 can rotate, so that the plants can be sprayed more evenly to ensure the quality of irrigation and avoid wasting water resources by irrigating a certain position multiple times;

[0054] The flow divider 30 rotates to drive the atomizing nozzle 38 to rotate and reciprocate up and down, so that plants can be irrigated in multiple ranges, saving the installation of traditional nozzles and saving water resources;

[0055] The rotation of the short rod 42 drives the connecting piece 33 and the arc-shaped piece 32 to rotate, so that the multiple arc-shaped pieces 32 no longer block the light-sensing receiver 31, and the debris on the arc-shaped piece 32 can be thrown out by centrifugal force to avoid blocking the light-sensing receiver 31 and affecting its receiving signal;

[0056] When the rectangular piston 16 moves upward, the water in the water storage cylinder 5 can be sucked into the rotating piston cylinder 12 through the first short tube 13. At this time, the water pressure in the water storage cylinder 5 is reduced, thereby causing the water pressure at the atomizing nozzle 38 to be reduced, reducing the spraying amount of the atomizing nozzle 38. When the rectangular piston 16 moves downward, the clean water in the rotating piston cylinder 12 can be discharged through the first short tube 13, thereby increasing the water pressure in the water storage cylinder 5, increasing the water pressure at the atomizing nozzle 38, and increasing the spraying amount of the atomizing nozzle 38. In this way, the spraying range is intermittently reduced and increased in a spiral shape, further ensuring uniform spraying of the plants.

[0057] When the light intensity or time increases and the spraying amount needs to be increased, the solenoid valve 14 on the first short tube 13 is closed, the electronic one-way control valve 15 on the second short tube 24 is opened, and the rectangular piston 16 moves upward, so that the water in the water supply cylinder 1 can be sucked into the rotating piston cylinder 12 through the vertical pipe 8. When the rectangular piston 16 moves downward, the water in the rotating piston cylinder 12 can be discharged into the water storage cylinder 5 through the second short tube 24, so that the water pressure in the water storage cylinder 5 can be increased, thereby increasing the water pressure at the atomizing nozzle 38, and increasing the spraying amount and spraying range at the atomizing nozzle 38, so that the plants can be irrigated more effectively and evenly;

[0058] After the irrigation is completed, the motor 7 and the water pump 43 are powered off and the rectangular piston 16 and the diverter box 30 are reset. The diverter box 30 is located in the receiving ring 3, which can protect the diverter box 30. The short rod 42 is reset under the action of the torsion spring, and the arc piece 32 is reset to cover and protect the light-sensing receiver 31, so that it is not easily affected by the external environment.

[0059] The arc block 36 is reset so that the atomizing nozzle 38 is stored in the U-shaped block 34. The U-shaped block 34 can shield the atomizing nozzle 38 to prevent it from being blocked by debris.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
