Description

Technical Field

[0001] This invention belongs to the field of agricultural and forestry irrigation technology, and specifically relates to a water-saving sprinkler irrigation device for agriculture and forestry. Background Technology

[0002] With the continuous advancement of agricultural and forestry planting technologies, large-scale cultivation and mixed cropping have become the mainstream development direction of the current agricultural and forestry industry. This model can make full use of land resources, increase planting yields and economic benefits, and enrich the diversity of agricultural and forestry ecosystems. Sprinkler irrigation systems are needed for the normal growth of plants, including water supply and pest and disease control.

[0003] In existing technologies, within the same plot of land or planting area, different types of plants, such as seedlings, low-growing crops, and low-growing shrubs, are often planted simultaneously. These plants vary in height and have different requirements for irrigation area, spray height, and water volume at different growth stages. Traditional sprinkler irrigation systems mostly use a fixed-height spray structure, which has a large coverage area but cannot individually irrigate plants of different heights or match the water requirements of different plants. This leads to some areas receiving excessive water while others receive insufficient water. For example, when irrigating taller plants, a large amount of water is also sprayed onto lower crops, easily causing waterlogging damage to the lower crops, which not only affects plant growth but also results in serious water waste. In addition, when sprinkler irrigating or spraying pesticides on low-growing shrubs, some water or pesticides will run off the branches and leaves due to excessive spraying, resulting in waste of water or pesticides. Summary of the Invention

[0004] This invention provides a water-saving sprinkler irrigation device for agriculture and forestry, aiming to solve the problem of poor practicality caused by the inability of existing sprinkler irrigation devices to match the scenarios of planting various types of plants in a shuttle manner and the easy waste of water / pesticide.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a water-saving sprinkler irrigation device for agriculture and forestry, comprising: The mobile base has wheels at the bottom and a water tank at the top. The first irrigation unit is installed on the movable base and is connected to the water supply tank. It has multiple water spray nozzles facing the ground for irrigating seedlings and low-growing crops. The second irrigation unit is mounted on the movable base and located above the first irrigation unit. The second irrigation unit is connected to the water supply tank. The second irrigation unit has two spray nozzles symmetrically arranged along the width of the movable base for spraying water or applying pesticides to the shrubs. The recycling unit, mounted on the movable base, has two collection sections corresponding to the two spray sections, for recycling the spilled liquid from the shrubs or the spray sections; The first irrigation unit and the second irrigation unit are used to be turned on independently or simultaneously to adjust the irrigation coverage and irrigation parameters in the shuttle planting scenario.

One end of each mounting rod is connected to both ends of the fixed rod, and the other end is connected to both ends of the connecting rod. The water spray structure is provided in two parts, and the two water spray structures are respectively installed on the two mounting rods; the water spray structure is the spraying part.

[0008] In one possible implementation, the second irrigation unit includes: A fixing rod is installed on the water supply tank and is arranged along the width direction of the movable seat; The connecting rods are parallel to and spaced apart from the fixed rods along the length of the movable seat; An adjusting component is located between the fixed rod and the connecting rod, and the adjusting component is hinged to the fixed rod and the connecting rod. The water spray structure has two components, which are symmetrically arranged along the width direction of the movable base and mounted on the adjustment component. The spray angle of the two water spray structures can be adjusted by the adjustment component. The water spray structure is the spraying part.

[0009] In one possible implementation, the regulating component includes: The first rod body is provided in two parts, and the two first rod bodies are spaced apart along the width direction of the movable seat body. One end of each of the two first rod bodies is hinged to both ends of the fixed rod. The second rod body is provided in two parts, which are spaced apart along the width direction of the movable seat body. One end of each of the two second rod bodies is hinged to the other end of the two first rod bodies, and the other end of each of the two second rod bodies is hinged to both ends of the connecting rod. The drive structure has a fixed end and a telescopic end, wherein the fixed end is connected to the fixed rod and the telescopic end is connected to the connecting rod; The two water spray structures are respectively installed on the corresponding first rod and second rod.

[0010] In one possible implementation, each of the water spray structures includes: Multiple second water spray pipes are provided, each second water spray pipe is arranged vertically, and each second water spray pipe is respectively installed on the corresponding first rod and the corresponding second rod; each second water spray pipe is provided with multiple second water spray nozzles; The second nozzle is provided in multiple parts, and each second nozzle is respectively located at each second water spray port.

[0011] In one possible implementation, the water-saving sprinkler irrigation device for agriculture and forestry further includes a pesticide storage structure; the pesticide storage structure includes: A storage bin has a holding cavity, the holding cavity having a material inlet and a material outlet; A movable blocking plate is installed at the discharge port and is slidably connected to the storage tank to block the discharge port; The driver has a telescopic end connected to the movable stop plate for driving the movable stop plate to slide.

[0012] In one possible implementation, the water-saving sprinkler irrigation device for agriculture and forestry further includes a stirring structure, the stirring structure comprising: A rotating shaft is rotatably mounted in the water supply tank. The stirring blades are provided in multiples, and each stirring blade is arranged circumferentially on the rotating shaft around the axis of the rotating shaft; A drive motor is installed in the water supply tank and is poweredly connected to the rotating shaft to drive the rotating shaft to rotate.

[0013] In one possible implementation, each of the recycling units includes: A collection box is mounted on the mounting frame and located below the corresponding spraying section; the upper end of the collection box is open. The guide pipe is connected at one end to the collection box and at the other end to the water supply box.

[0014] In one possible implementation, the movable seat includes: The support plate has a mounting surface at the top for installing a water supply tank; Multiple mounting plates are provided, and each mounting plate is evenly arranged at the bottom end of the support plate; There are two connecting shafts, each of which is rotatably connected to a mounting plate. Each connecting shaft has a walking wheel installed at both ends.

[0015] This invention provides a water-saving sprinkler irrigation device for agriculture and forestry. Compared with existing technologies, the first irrigation unit has a lower spray height and can be opened independently. Combined with the mobility of the movable base, it can specifically irrigate seedlings and low-growing crops. Multiple spray nozzles facing the ground in the first irrigation unit ensure precise coverage of plant roots, avoiding water wastage caused by improper height in traditional sprinkler irrigation, while also meeting the individual water supply needs of these plants during their growth. The second irrigation unit, located above the first unit, can also be opened independently. Combined with the mobility of the movable base, two spray nozzles symmetrically arranged along the width of the movable base can precisely spray water or pesticides onto low-growing shrubs of a certain height on both sides. This symmetrical arrangement expands the spray angle and range, adapting to the height changes and crown size of shrubs at different growth stages. Furthermore, the first and second irrigation units can be activated simultaneously. When activated simultaneously, the water output of each unit can be adjusted—for example, the first irrigation unit can output less water while the second unit outputs more water—to match the water requirements of various plants after a single movement of the mobile platform. The device as a whole is highly adaptable and can accommodate various scenarios involving the planting of different types of plants.

[0016] The independent control of the first and second irrigation units allows for flexible adjustment of spraying duration, volume, and coverage based on the water requirements and growth stages of different plants. This targeted coverage ensures efficient water distribution, avoiding the water waste associated with traditional sprinkler irrigation. For example, when irrigating seedlings with low water requirements, only the first irrigation unit needs to be activated and adjusted to the appropriate volume; the second unit can be used, reducing ineffective water consumption at the source. Conversely, when watering shrubs of a certain height, the second irrigation unit allows for precise spraying, ensuring that water primarily reaches the canopy and root zone, preventing water from spreading to other areas and causing waste.

[0017] On the other hand, the spraying section of the second irrigation unit can also be used for spraying pesticides, offering multiple functions. The two collection sections of the recovery unit correspond to the two spraying sections of the second irrigation unit. During watering or pesticide spraying of shrubs, when excess water or pesticide drips from the shrubs, the collection sections can promptly collect it. This recovered water can be reintroduced into the water supply tank for recycling, reused for irrigation or pest control, forming a closed-loop water resource cycle and reducing water or pesticide waste to some extent. The recovered water can be reused for sprinkler irrigation, achieving water conservation; while the recovered pesticide can be reused for spraying, reducing pesticide consumption costs and avoiding the risk of pesticide damage caused by some pesticide dripping directly onto low-lying crops below.

[0024] To make it easier to understand, consider the scenario of planting different types of plants such as seedlings, low-growing crops, and low-growing shrubs in a way that creates gaps between two rows of low-growing shrubs of a certain height, and then planting low-growing crops in these gaps.

[0025] Please refer to the following: Figures 1 to 5This invention provides a water-saving sprinkler irrigation device for agriculture and forestry. The device includes a movable base 10, a first irrigation unit 20, a second irrigation unit 30, and a recovery unit 60. The movable base 10 has wheels 11 at its bottom and a water tank 12 at its top. The first irrigation unit 20 is mounted on the movable base 10 and connected to the water tank 12. It has multiple spray nozzles facing the ground for irrigating seedlings and low-growing crops. The second irrigation unit 30 is mounted on the movable base 10 and located above the first irrigation unit 20. It is connected to the water tank 12. The second irrigation unit 30 has two spray nozzles 31 symmetrically arranged along the width direction 70 of the movable base for watering shrubs or spraying pesticides. The recycling unit 60 is mounted on the movable base 10 and has two collection sections corresponding to the two spray sections 31, respectively, for recycling the pesticide solution overflowing from the shrubs or spray sections 31. The first irrigation unit 20 and the second irrigation unit 30 can be activated independently or simultaneously to adjust the irrigation coverage and parameters in a mobile planting scenario.

[0026] In this embodiment, the top of the mobile base 10 has a water supply tank 12. A first irrigation unit 20 is mounted on the mobile base 10 and connected to the water supply tank 12, thereby providing water resources to the first irrigation unit 20 through the water supply tank 12. The first irrigation unit 20 has multiple spray nozzles facing the ground to irrigate seedlings and low-growing crops. A second irrigation unit 30 is mounted on the mobile base 10 and located above the first irrigation unit 20. The second irrigation unit 30 is connected to the water supply tank 12, thereby providing water resources to the second irrigation unit 30 through the water supply tank 12. The second irrigation unit 30 has two spray nozzles 31 symmetrically arranged along the width direction 70 of the mobile base for spraying water or spraying pesticides on shrubs. The first irrigation unit 20 and the second irrigation unit 30 can be turned on independently or simultaneously to adjust the irrigation coverage and irrigation parameters in a mobile planting scenario. The recycling unit 60 is mounted on the movable base 10 and has two collection sections, which correspond to two spray sections 31 respectively, for recycling the liquid medicine flowing down from the shrubs or overflowing from the spray sections 31.

[0027] This invention provides a water-saving sprinkler irrigation device for agriculture and forestry. Compared with the prior art, the movable base 10 has a water supply tank 12 at its top. A first irrigation unit 20 is mounted on the movable base 10 and connected to the water supply tank 12, thereby providing water resources to the first irrigation unit 20 through the water supply tank 12. The first irrigation unit 20 has multiple spray sections facing the ground, thereby irrigating seedlings and low-growing crops through each spray section. A second irrigation unit 30 is disposed on the movable base 10 and located above the first irrigation unit 20. The second irrigation unit 30 has two spray sections 31 symmetrically arranged along the width direction 70 of the movable base, used for watering shrubs or spraying pesticides. The independent control of the first irrigation unit 20 and the second irrigation unit 30 allows for flexible adjustment of irrigation parameters such as spraying duration, spray volume, and spray range according to the water requirements of different plants and their growth stages. The spray range can specifically cover the target plants, avoiding water waste caused by large-scale spraying in traditional sprinkler irrigation. For example, when irrigating seedlings with low water requirements, only the first irrigation unit 20 needs to be turned on and adjusted to a suitable spray volume, without needing to activate the second irrigation unit 30, thus reducing ineffective water consumption at the source. When spraying shrubs of a certain height, the second irrigation unit 30 can be adjusted for precise spraying, ensuring that the water mainly acts on the shrub canopy and root area, preventing water from spreading to other areas and causing waste.

[0028] In this embodiment, the first irrigation unit 20 and the second irrigation unit 30 can be activated simultaneously. Simultaneous activation can be achieved by adjusting the water output of each unit; this can be done via a control valve. For example, the first irrigation unit 20 can output less water, while the second irrigation unit 30 can output more water, thus matching the water requirements of various plants after a single movement of the mobile base 10. The device as a whole has high adaptability and can accommodate various scenarios involving the planting of different types of plants.

[0029] In addition, in this embodiment, the spraying part 31 of the second irrigation unit 30 can also be used for spraying pesticides, thus having multiple functions.

[0030] The two collection sections of the recycling unit 60 correspond to the two spray sections 31 of the second irrigation unit 30. During the spraying of water or pesticides on the shrubs, when excess water or pesticide solution flows down from the shrubs, the collection sections can promptly collect it. This collected water can be reintroduced into the water supply tank 12 for recycling, and reused for irrigation or pest control operations, forming a closed-loop water resource cycle, which reduces the loss and waste of water resources or pesticide solution to a certain extent. The recycled water can be reused for sprinkler irrigation, achieving water conservation; while the recycled pesticide solution can be reused for pesticide spraying, which not only reduces the cost of pesticide consumption, but also avoids the risk of pesticide damage caused by some pesticide solution dripping directly onto the low-lying crops below.

[0031] In some embodiments, please refer to Figure 4 The first irrigation unit 20 includes a mounting frame 21, a first water spray pipe 22, and a first nozzle.
