Description

Technical Field

[0001] This utility model relates to the field of forest irrigation, and in particular to a water-saving forest seedling irrigation device. Background Technology

[0002] In the field of forest seedling cultivation, traditional irrigation methods have many problems. In order to overcome the limitations of traditional irrigation methods, some new water-saving irrigation devices have emerged in recent years. These technologies aim to improve irrigation efficiency, reduce water waste, adapt to different environments, and promote the healthy growth of seedlings.

[0003] Although new water-saving irrigation devices can reduce water waste, they cannot automatically control the amount of water used for irrigation based on temperature and humidity, resulting in reduced water utilization efficiency and the inability to dynamically adjust the equipment. Therefore, those skilled in the art provide a water-saving forest seedling irrigation device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-saving irrigation device for forest seedling cultivation. This device allows for automatic control of irrigation volume based on temperature and humidity, reducing water waste and promoting the healthy growth of seedlings.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-saving forest seedling irrigation device, comprising a base plate, a hydraulic cylinder provided on the upper end surface of the base plate, a support plate fixedly connected to the upper end surface of the hydraulic cylinder, and an irrigation structure provided on the upper end surface of the support plate;

[0006] The irrigation structure includes a water storage tank, a first rotating cylinder rotatably connected to the upper end of the water storage tank, a rotating shaft located at the center of the inner circle of the first rotating cylinder, five spiral fan blades fixedly connected to the output end of the rotating shaft, the side of the five spiral fan blades away from the rotating shaft being fixedly connected to the first rotating cylinder, five atomizing nozzles evenly distributed in a symmetrical arrangement on the outer surface of the first rotating cylinder, a rotating cylinder cover fixedly connected to the upper end of the first rotating cylinder, a second rotating cylinder fixedly connected to the center of the upper end of the rotating cylinder cover, five scattering nozzles evenly distributed in a symmetrical arrangement on the outer surface of the second rotating cylinder, a temperature sensor located at the center of the upper end of the second rotating cylinder, and a humidity sensor located at the center of the upper end of the temperature sensor.

[0007] The outer side of the irrigation structure is provided with an irrigation inlet, and the input end of the irrigation inlet is provided with a first valve;

[0008] With the above technical solution, the lifting and lowering of the support plate is controlled by the hydraulic cylinder on the base plate during use. The support plate drives the irrigation structure to rise or fall, thereby adjusting the height of the device. When irrigation is needed, water is injected into the water storage tank through the irrigation inlet. When the water level in the storage tank reaches the first rotating drum, the force of the rising water level drives the spiral fan blades inside the first rotating drum to rotate around the shaft. Because the outer surface of the first rotating drum is equipped with atomizing nozzles, the water can be atomized and sprayed outward from the inside of the first rotating drum through the atomizing nozzles. At the same time, the rotation of the first rotating drum under the force drives the atomizing nozzles to rotate around the center, thereby spraying the water evenly. When the water level reaches the second rotating drum, because the outer surface of the second rotating drum is equipped with scattering nozzles, the water can be scattered outward from the inside of the second rotating drum through the scattering nozzles.

[0009] Because the first rotating drum, the drum cover, and the second rotating drum are all fixedly connected, the rotation of the first rotating drum can drive the rotation of the second rotating drum, thereby causing the scattering nozzles to spray water evenly. Because the irrigation structure is equipped with temperature and humidity sensors at the top, when the temperature sensor detects that the outdoor temperature is high, it controls the scattering nozzles to open and increase the irrigation volume. When the temperature is low, it controls the scattering nozzles to close and stop irrigation. When the humidity sensor detects that the humidity is low, it controls the atomizing nozzles to open. When the humidity is high, it controls the atomizing nozzles to close. When the temperature sensor detects that the temperature is high but the humidity sensor detects that the humidity is high, it controls the scattering nozzles to close and the atomizing nozzles to open, dynamically adjusting the irrigation volume and saving water resources.

[0010] Because the inlet of the irrigation system is equipped with a first valve, the water pressure can be controlled by turning the first valve, thereby controlling the rotation speed of the first drum.

[0011] Furthermore, three supports are evenly distributed in a symmetrical manner on the lower end surface of the substrate. Each of the three supports is provided with a fixing device at its lower end. Each of the three fixing devices includes three bases. The three bases are respectively fixedly connected to the lower end of the three supports. The lower end surface of the three bases is provided with a fixing plate. The lower end surface of the three fixing plates is evenly provided with twelve fixing screws in a symmetrical manner on its lower end surface. A cone head is fixedly provided at the center of the lower end surface of the three fixing plates. The twelve fixing screws pass through the lower end surface of the three fixing plates and extend to the upper end of the three fixing plates. The ends are respectively threaded to the lower end surface of the three bases.

[0012] With the above technical solution, because the lower end of the substrate is provided with three supports, and the lower end of the supports is provided with a fixing device, when it is necessary to fix the device to the ground, the cone head can be inserted into the ground to fix the device. When it is necessary to place the device on the flat ground, the fixing plate can be removed by removing the fixing screws, thereby removing the cone head, and the base can directly contact the ground. The detachable structure makes the device suitable for various scenarios.

[0013] Furthermore, a water tank body is provided on the lower end face of the substrate, and a water pump is fixedly connected to the center of the lower end face of the water tank body. A second valve is provided at the input end of the water pump, and a water tank outlet pipe is connected to the output end of the second valve. The end of the water tank outlet pipe away from the second valve is connected to the lower end face of the water tank body. A third valve is provided at the output end of the water pump, and a connecting pipe is connected to the output end of the third valve. The end of the connecting pipe away from the third valve is connected to the irrigation inlet. A water tank inlet is provided on the outer side face of the water tank body, and a rubber stopper is provided at the input end of the water tank inlet.

[0014] With the above technical solution, since a water tank is installed at the lower end of the substrate, water can be pre-filled into the water tank through the water inlet, thereby achieving the function of water storage. When water in the water tank needs to be used, the second valve and the third valve can be opened to allow water to flow from the water tank outlet pipe into the water pump. After being pressurized by the water pump, the water flows out from the connecting pipe to the irrigation inlet. When it is not necessary to continue filling the water tank, a rubber stopper can be inserted into the water tank inlet to prevent liquid from spilling out.

[0015] Furthermore, the lower surfaces of all three bases are decorated with printed patterns;

[0016] The above technical solution involves printing a pattern on the lower surface of the base to prevent it from sliding when in contact with the ground.

[0017] Furthermore, the spiral fan blades, the second rotating drum, the drum cover, the rotating shaft, and the first rotating drum are all made of lightweight and high-hardness plastic material;

[0018] With the above technical solution, since the spiral fan blades, the second rotating drum, the drum cover, the rotating shaft and the first rotating drum are all made of lightweight and hard plastic, the water flow can easily drive them to rotate, avoiding the situation where the water pressure is insufficient to drive them to rotate.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, a temperature sensor and a humidity sensor are provided at the upper end of the irrigation structure. When the temperature sensor detects that the outdoor temperature is high, it controls the diffuser to open and increase the irrigation volume. When the temperature is low, it controls the diffuser to close and stop irrigation. When the humidity sensor detects that the humidity is low, it controls the atomizing nozzle to open. When the humidity is high, it controls the atomizing nozzle to close. When the temperature sensor detects that the temperature is high but the humidity sensor detects that the humidity is high, it controls the diffuser to close and the atomizing nozzle to open, thus dynamically adjusting the irrigation volume and saving water resources.

[0021] 2. In this utility model, the lower end face of the base plate is provided with three supports, and the lower end of the supports is provided with a fixing device. When it is necessary to fix the device to the mud, the cone head can be inserted into the mud to fix the device. When it is necessary to place the device on the flat ground, the fixing plate can be removed by disassembling the fixing screws, thereby removing the cone head and directly contacting the ground through the base. The detachable structure makes the device suitable for various scenarios.

[0022] 3. In this utility model, a water tank is installed at the lower end of the base plate. Water can be pre-filled into the water tank through the water tank inlet, thereby achieving the function of water storage and making it suitable for various environments. When water in the water tank needs to be used, the second valve and the third valve can be opened to allow water to flow from the water tank outlet pipe into the water pump. After being pressurized by the water pump, the water flows out from the connecting pipe to the irrigation inlet. When it is not necessary to continue filling the water tank, a rubber stopper can be inserted into the water tank inlet to prevent liquid from spilling out. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1-6 An embodiment of this utility model is provided: a water-saving forest seedling irrigation device, including a base plate 1, a hydraulic cylinder 3 is provided on the upper end surface of the base plate 1, a support plate 4 is fixedly connected to the upper end surface of the hydraulic cylinder 3, and an irrigation structure 6 is provided on the upper end surface of the support plate 4.

[0035] like Figure 1 , 3 As shown in Figure 5, the irrigation structure 6 includes a water storage tank 601. A first rotating cylinder 609 is rotatably connected to the upper end of the water storage tank 601. A rotating shaft 608 is provided at the center of the inner circle of the first rotating cylinder 609. Five spiral fan blades 603 are fixedly connected to the output end of the rotating shaft 608. The side of the five spiral fan blades 603 away from the rotating shaft 608 is fixedly connected to the first rotating cylinder 609. Five atomizing nozzles 602 are evenly distributed in a symmetrical manner on the outer surface of the first rotating cylinder 609. A rotating cylinder cover 607 is fixedly connected to the upper end of the first rotating cylinder 609. A second rotating cylinder 606 is fixedly connected to the center of the upper end of the rotating cylinder cover 607. Five scattering nozzles 610 are evenly distributed in a symmetrical manner on the outer surface of the second rotating cylinder 606. A temperature sensor 604 is provided at the center of the upper end of the second rotating cylinder 606. A humidity sensor 605 is provided at the center of the upper end of the temperature sensor 604.

[0036] The outer side of the irrigation structure 6 is provided with an irrigation inlet 7, and the input end of the irrigation inlet 7 is provided with a first valve 12.

[0037] In use, the hydraulic cylinder 3 on the base plate 1 controls the raising and lowering of the support plate 4. The support plate 4 drives the irrigation structure 6 to rise or fall, thereby adjusting the height of the device. When irrigation is needed, water is injected into the water storage tank 601 through the irrigation inlet 7. When the water level in the water storage tank 601 reaches the first rotating drum 609, the force of the rising water level drives the spiral fan blades 603 inside the first rotating drum 609 to rotate around the rotating shaft 608. Because the outer surface of the first rotating drum 609 is equipped with atomizing nozzles 602, water can flow from the first rotating drum 609. The water is atomized and sprayed outward through the atomizing nozzle 602 inside the cylinder. At the same time, the first rotating cylinder 609 rotates under the force, causing the atomizing nozzle 602 to rotate around the center, thereby spraying the water evenly. When the liquid level reaches the second rotating cylinder 606, because the outer surface of the second rotating cylinder 606 is provided with a scattering nozzle 610, the water flow can be scattered outward from the inside of the second rotating cylinder 606 through the scattering nozzle 610. A first valve 12 is provided at the input end of the irrigation inlet 7. The water pressure can be controlled by turning the first valve 12, thereby controlling the rotation speed of the first rotating cylinder 609.

[0038] Because the first rotating drum 609, the rotating drum cover 607, and the second rotating drum 606 are all fixedly connected, the rotation of the first rotating drum 609 can drive the second rotating drum 606 to rotate, thereby causing the diffuser 610 to spray water evenly. Because the irrigation structure 6 is equipped with a temperature sensor 604 and a humidity sensor 605 at the upper end, when the temperature sensor 604 detects that the outdoor temperature is high, it controls the diffuser 610 to open to increase the irrigation volume. When the temperature is low, it controls the diffuser 610 to close to stop irrigation. When the humidity sensor 605 detects that the humidity is low, it controls the atomizing nozzle 602 to open. When the detected humidity is high, it controls the atomizing nozzle 602 to close. When the temperature sensor 604 detects that the temperature is high but the humidity sensor 605 detects that the humidity is high, it controls the diffuser 610 to close and the atomizing nozzle 602 to open.

[0039] When it is not necessary to continue filling the water tank 2, a rubber stopper 11 can be inserted into the water inlet 10 of the water tank to prevent liquid from spilling out.

[0040] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, three supports 5 are evenly distributed in a symmetrical manner on the lower end face of the substrate 1. Each of the three supports 5 is provided with a fixing device 9 at its lower end. Each fixing device 9 includes three bases 901. The three bases 901 are fixedly connected to the lower ends of the three supports 5. The lower end face of the three bases 901 is provided with a fixing plate 904. The lower end face of the three fixing plates 904 is evenly provided with twelve fixing screws 903 in a symmetrical manner. A cone head 902 is fixed at the center of the lower end face of the three fixing plates 904. The twelve fixing screws 903 pass through the lower end face of the three fixing plates 904 and extend to the upper end of the three fixing plates 904, and their ends are threadedly connected to the lower end face of the three bases 901.

[0041] Three supports 5 are provided at the lower end of the base plate 1, and a fixing device 9 is provided at the lower end of the supports 5. When the device needs to be fixed on the ground, the cone head 902 can be inserted into the ground to stabilize the device. When the device needs to be placed on flat ground, the fixing plate 904 can be removed by removing the fixing screw 903, thereby removing the cone head 902 and making the base 901 directly contact the ground. The detachable structure makes the device suitable for various scenarios.

[0042] A water tank body 2 is provided on the lower end face of the substrate 1. A water pump 8 is fixedly connected to the center of the lower end face of the water tank body 2. A second valve 14 is provided at the input end of the water pump 8. A water tank outlet pipe 16 is connected to the output end of the second valve 14. The end of the water tank outlet pipe 16 away from the second valve 14 is connected to the lower end face of the water tank body 2. A third valve 15 is provided at the output end of the water pump 8. A connecting pipe 13 is connected to the output end of the third valve 15. The end of the connecting pipe 13 away from the third valve 15 is connected to the irrigation inlet 7. A water tank inlet 10 is provided on the outer side of the water tank body 2. A rubber stopper 11 is provided at the input end of the water tank inlet 10.

[0043] Because the lower end of the base plate 1 is equipped with a water tank body 2, water can be pre-filled into the water tank body 2 through the water tank inlet 10, thereby achieving the function of water storage. When the water in the water tank body 2 needs to be used, the second valve 14 and the third valve 15 can be opened to allow water to flow from the water tank outlet pipe 16 into the water pump 8. After being pressurized by the water pump 8, the water flows out from the connecting pipe 13 to the irrigation inlet 7. When it is not necessary to continue filling the water tank body 2 with water, a rubber stopper 11 can be inserted into the water tank inlet 10 to prevent liquid from spilling out.

[0044] The bottom surfaces of all three bases 901 are printed with patterns.

[0045] A print is printed on the lower end of the base 901 to prevent the base 901 from sliding when it comes into contact with the ground.

[0046] The spiral fan blade 603, the second rotating drum 606, the rotating drum cover 607, the rotating shaft 608, and the first rotating drum 609 are all made of lightweight and high-hardness plastic.

[0047] Because the spiral fan blades 603, the second rotating drum 606, the rotating drum cover 607, the rotating shaft 608, and the first rotating drum 609 are all made of lightweight and sturdy plastic, water flow can easily drive them to rotate, avoiding the situation where the water pressure is insufficient to drive them to rotate.

[0048] Working principle: Three supports 5 are provided at the lower end of the base plate 1, and a fixing device 9 is provided at the lower end of the support 5. When it is necessary to fix the device to the ground, the cone head 902 can be inserted into the ground to stabilize the device. When it is necessary to place the device on the flat ground, the fixing plate 904 can be removed by removing the fixing screw 903, thereby removing the cone head 902 and making the base 901 directly contact the ground. The detachable structure makes the device suitable for various scenarios.

[0049] Because the lower end of the base plate 1 is equipped with a water tank body 2, water can be pre-filled into the water tank body 2 through the water tank inlet 10, thereby achieving the function of water storage. When water in the water tank body 2 is needed, the second valve 14 and the third valve 15 can be opened to allow water to flow from the water tank outlet pipe 16 into the water pump 8. After being pressurized by the water pump 8, the water flows out from the connecting pipe 13 to the irrigation inlet 7. When it is not necessary to continue filling the water tank body 2 with water, a rubber stopper 11 can be inserted into the water tank inlet 10 to prevent liquid from spilling out.

[0050] In use, the hydraulic cylinder 3 on the base plate 1 controls the raising and lowering of the support plate 4. The support plate 4 drives the irrigation structure 6 to rise or fall, thereby adjusting the height of the device. When irrigation is needed, water is injected into the water storage tank 601 through the irrigation inlet 7. When the water level in the water storage tank 601 reaches the first rotating drum 609, the force of the rising water level drives the spiral fan blades 603 inside the first rotating drum 609 to rotate around the rotating shaft 608. Because the outer surface of the first rotating drum 609 is equipped with atomizing nozzles 602, water can flow from the first rotating drum 609. The water is atomized and sprayed outward through the atomizing nozzle 602 inside the cylinder. At the same time, the first rotating cylinder 609 rotates under the force, causing the atomizing nozzle 602 to rotate around the center, thereby spraying the water evenly. When the liquid level reaches the second rotating cylinder 606, because the outer surface of the second rotating cylinder 606 is provided with a scattering nozzle 610, the water flow can be scattered outward from the inside of the second rotating cylinder 606 through the scattering nozzle 610. A first valve 12 is provided at the input end of the irrigation inlet 7. The water pressure can be controlled by turning the first valve 12, thereby controlling the rotation speed of the first rotating cylinder 609.

[0051] Because the first rotating drum 609, the rotating drum cover 607, and the second rotating drum 606 are all fixedly connected, the rotation of the first rotating drum 609 can drive the second rotating drum 606 to rotate, thereby causing the diffuser 610 to spray water evenly. Because the irrigation structure 6 is equipped with a temperature sensor 604 and a humidity sensor 605 at the upper end, when the temperature sensor 604 detects that the outdoor temperature is high, it controls the diffuser 610 to open to increase the irrigation volume. When the temperature is low, it controls the diffuser 610 to close to stop irrigation. When the humidity sensor 605 detects that the humidity is low, it controls the atomizing nozzle 602 to open. When the detected humidity is high, it controls the atomizing nozzle 602 to close. When the temperature sensor 604 detects that the temperature is high but the humidity sensor 605 detects that the humidity is high, it controls the diffuser 610 to close and the atomizing nozzle 602 to open.

[0052] A print is printed on the lower end of the base 901 to prevent the base 901 from sliding when it comes into contact with the ground.

[0053] Because the spiral fan blades 603, the second rotating drum 606, the rotating drum cover 607, the rotating shaft 608, and the first rotating drum 609 are all made of lightweight and sturdy plastic, water flow can easily drive them to rotate, avoiding the situation where the water pressure is insufficient to drive them to rotate.

[0054] The equipment also includes a PLC controller. Temperature sensor 604 and humidity sensor 605 are two commonly used sensors in many control systems. They sense changes in temperature and humidity in the environment, convert these physical quantities into electrical signals, and these signals are processed to serve as the basis for control decisions. The PLC controller then uses a control algorithm to process the input signals and generate control outputs according to predetermined rules. Based on the results of the control algorithm, the PLC controller sends signals to the actuators through its output port. The PLC controller can coordinate the work of various components to achieve control of the equipment. In practical applications, temperature sensor 604 and humidity sensor 605 are often used together to achieve comprehensive environmental control, which is a commonly used technique in existing temperature control methods and will not be elaborated further here.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
