Description

Technical Field

[0001] This utility model belongs to the field of vegetable cultivation technology, and in particular relates to an irrigation device for agricultural vegetable cultivation with adjustable water flow. Background Technology

[0002] In the field of agricultural vegetable farming, irrigation is a key link to ensure vegetable growth and improve yield and quality. Different types of vegetables (such as leafy vegetables and melons) have significantly different water requirements at different growth stages (germination stage, seedling stage, and mature stage). Furthermore, the dynamic changes in soil moisture and climate conditions (such as temperature, humidity, and wind speed) in the field all require irrigation devices to have the ability to flexibly adjust the water flow to achieve differentiated and precise irrigation.

[0003] The inventors discovered that at least the following problems remain unresolved in existing technologies: Most mainstream agricultural vegetable irrigation devices on the market currently use nozzles with fixed orifice diameters or simple valves to control water flow; the coordination between changes in water flow and the spraying effect of the nozzles is poor, and the nozzle size cannot be adjusted synchronously when the water flow changes. When the water flow decreases, it leads to insufficient spray pressure, which in turn reduces the irrigation area.

[0004] Therefore, we propose an irrigation device for agricultural vegetable cultivation with adjustable water flow, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an agricultural vegetable cultivation irrigation device with adjustable water flow, achieving the effect of simultaneously matching the spray pressure and irrigation range.

[0006] In view of this, the present invention provides an irrigation device for agricultural vegetable cultivation with adjustable water flow, including a nozzle housing. A spray chamber is formed inside the lower end of the nozzle housing. Water nozzles are equidistantly spaced in a ring on the sidewall of the spray chamber. A water inlet groove is vertically formed through one side of the inner wall at the top of the spray chamber. A pipe connector is fixedly installed at the top of the water inlet groove. An adjustment mechanism is provided inside the water inlet groove for adjusting the water flow rate. A control mechanism is provided inside the spray chamber for controlling the size of the sprayed water column. A detection component is provided on one side of the adjustment mechanism for detecting the opening degree of the water inlet groove.

[0007] Furthermore, the adjustment mechanism includes two sets of adjustment plates for adjusting the opening amount of the water inlet tank, and a small servo motor for driving the adjustment plates to rotate. The two sets of adjustment plates are symmetrically installed on the outside of the drive rod. The shaft end of the servo motor is fixedly connected to the end of the drive rod away from the adjustment plate. The drive rod is rotatably connected to the inner walls of both sides of the water inlet tank through bearings. The servo motor is fixedly connected to the outside of the nozzle housing.

[0008] Furthermore, the adjusting plate is placed inside the water inlet tank, and the size of the adjusting plate matches that of the water inlet tank.

[0009] Furthermore, the control mechanism includes a water jet hole for controlling the size of the water jet, and a turntable for driving the water jet hole to rotate. The water jet holes are equidistantly arranged in the middle of the control plate from left to right, and the diameter of the water jet holes decreases sequentially. The water jet holes in the middle of the control plate correspond to the water spray nozzles opened on the nozzle housing.

[0010] Furthermore, fixed rods are installed at equal intervals on the outer side of the turntable, and the end of each set of fixed rods away from the turntable is fixedly connected to one end of each set of control panels. A connecting rod is vertically fixedly installed in the middle of the upper surface of the turntable.

[0011] Furthermore, a control groove is provided on one side of the water inlet groove. The end of the connecting rod away from the turntable is placed inside the control groove and fixedly connected to the middle of the bottom side of the large bevel gear. The connecting rod is rotatably connected to the inner wall of the bottom end of the control groove through a sealed bearing. The drive rod is placed inside the control groove, passes through the middle of the small bevel gear, and is fixedly connected to the small bevel gear. The small bevel gear meshes with the large bevel gear.

[0012] Furthermore, inverted L-shaped limiting blocks are equidistantly installed on the side wall of the water spray chamber. The limiting blocks are positioned above the water spray nozzle and correspond to the water spray nozzle, and the control plate is slidably connected to the limiting blocks.

[0013] Furthermore, the detection assembly includes a magnet and a Hall sensor for detecting the rotation angle of the drive rod. The magnet is installed in a ring at equal intervals on the outside of the drive rod, and the Hall sensor is fixedly connected to the inner wall of the top of the control slot. The magnet corresponds to the Hall sensor, and a controller is provided on the upper part of the nozzle housing near the servo motor.

[0014] The beneficial effects of this utility model are: 1. The water flow rate in the inlet trough can be adjusted according to the actual irrigation needs of vegetables via an adjustment mechanism inside the inlet trough. The control mechanism inside the spray chamber works in conjunction with the adjustment mechanism; when the adjustment mechanism reduces the water flow, the control mechanism automatically adjusts its structure to reduce the size of the spray nozzles. This effectively prevents insufficient spray pressure due to reduced water flow, thus preventing a reduction in the irrigation area and ensuring stable irrigation coverage. Simultaneously, a detection component on one side of the adjustment mechanism can monitor the opening of the inlet trough in real time, providing data for precise water flow control. Ultimately, this achieves coordinated regulation of irrigation water flow and spraying effect, meeting the differentiated irrigation needs of vegetable farming. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1 to 3 An irrigation device for agricultural vegetable cultivation with adjustable water flow includes a nozzle housing 1. A water spraying chamber 11 is formed inside the lower end of the nozzle housing 1. Water spray nozzles 12 are equidistantly spaced in a ring on the sidewall of the water spraying chamber 11. A water inlet groove 13 is vertically inserted through one side of the inner wall of the top of the water spraying chamber 11. A pipe connector 14 is fixedly installed at the top of the water inlet groove 13. An adjustment mechanism is provided inside the water inlet groove 13 to adjust the water flow rate. A control mechanism is provided inside the water spraying chamber 11 to control the size of the sprayed water column. A detection component is provided on one side of the adjustment mechanism to detect the opening degree of the water inlet groove 13.

[0018] The water inlet trough 13, vertically penetrating one side of the inner wall of the top of the spray chamber 11, allows external water to be introduced into the device. A pipe connector 14 fixedly installed at its top ensures a stable connection to an external water supply pipeline, guaranteeing a continuous water supply. An adjustment mechanism inside the water inlet trough 13 allows for adjustment of the water flow rate according to the actual irrigation needs of the vegetables. A control mechanism inside the spray chamber 11 works in conjunction with the adjustment mechanism; when the adjustment mechanism reduces the water flow rate, the control mechanism automatically adjusts its structure to reduce the size of the spray nozzles 31. This effectively prevents insufficient spray pressure due to reduced water flow, thus preventing a reduction in the irrigation area and ensuring stable irrigation coverage. Simultaneously, a detection component on one side of the adjustment mechanism can detect the opening of the water inlet trough 13 in real time, providing data for precise control of the water flow rate. Ultimately, this achieves coordinated control of irrigation water flow and spraying effect, meeting the differentiated irrigation needs of vegetable cultivation.

[0019] Furthermore, the adjustment mechanism includes two sets of adjustment plates 2 for adjusting the opening amount of the water inlet tank 13, and a small servo motor 22 for driving the adjustment plates 2 to rotate. The two sets of adjustment plates 2 are symmetrically installed on the outside of the drive rod 21. The shaft end of the servo motor 22 is fixedly connected to the end of the drive rod 21 away from the adjustment plate 2. The drive rod 21 is rotatably connected to the inner walls of both sides of the water inlet tank 13 through bearings. The servo motor 22 is fixedly connected to the outside of the nozzle housing 1.

[0020] When a reduction in water flow is needed, the controller 26 sends a command to the servo motor 22. After starting, the servo motor 22 drives the drive rod 21, which is fixedly connected to its shaft, to rotate. As the drive rod 21 rotates, it simultaneously drives the two sets of adjusting plates 2 to rotate within the water inlet trough 13, increasing the area of ​​the water flow channel blocked by the adjusting plates 2, thereby reducing the water flow entering the spray chamber 11 through the water inlet trough 13. Conversely, if an increase in water flow is required, the servo motor 22 drives the drive rod 21 to rotate in the opposite direction, reducing the area of ​​the adjusting plates 2 blocking the water inlet trough 13, and thus increasing the water flow. Simultaneously, the rotation of the drive rod 21 synchronously drives the subsequent control mechanism, providing the power basis for the automatic adjustment of the spray hole 31 size, ensuring that changes in water flow and adjustments to the spray hole 31 size are synchronized, and preventing the irrigation area from being affected.

[0021] Furthermore, the adjusting plate 2 is placed inside the water inlet tank 13, and the size of the adjusting plate 2 matches that of the water inlet tank 13.

[0022] When the servo motor 22 drives the adjusting plate 2 to rotate in the water inlet tank 13 via the drive rod 21, the water inlet tank 13 can be blocked when the two sets of adjusting plates 2 rotate to the horizontal state, and the water inlet tank 13 is opened to the maximum extent when the two sets of adjusting plates 2 rotate to the vertical state.

[0023] Furthermore, the control mechanism includes a water jet hole 31 for controlling the size of the water jet, and a turntable 32 for driving the water jet hole 31 to rotate. The water jet holes 31 are equidistantly arranged in the middle of the control plate 3 from left to right, and the diameter of the water jet holes 31 decreases sequentially. The water jet holes 31 in the middle of the control plate 3 correspond to the water jet openings 12 in the nozzle housing 1.

[0024] When the regulating mechanism reduces the water flow, the turntable 32 rotates under the drive of the linkage structure, which in turn drives the control plate 3 to rotate synchronously. Since the diameters of the spray holes 31 are gradient-distributed, during the rotation of the control plate 3, the spray holes 31 corresponding to the spray nozzles 12 automatically switch to smaller diameter specifications. The smaller diameter spray holes 31 can compensate for the pressure loss caused by the reduced water flow by narrowing the cross-section of the water flow channel, maintaining stable pressure when the water is sprayed out, and preventing a shortened spray range due to reduced water flow. This ensures that the irrigation area is not reduced and that the vegetable planting area is evenly covered. It should be noted that a sealing ring can be provided on the side of the spray nozzle 12 near the control plate 3 to improve the sealing between the inner wall of the spray chamber 11 and the control plate 3. When the spray holes 31 of the control plate 3 are aligned with the spray nozzles 12, water spraying can be performed more stably.

[0025] Furthermore, fixed rods 33 are equidistantly installed on the outer side of the turntable 32, and the end of each set of fixed rods 33 away from the turntable 32 is fixedly connected to one end of each set of control plates 3. A connecting rod 34 is vertically fixedly installed in the middle of the upper surface of the turntable 32.

[0026] When the turntable 32 rotates, it synchronously drives the control plates 3 to rotate via the outer fixing rod 33, so that the water spray holes 31 of different diameters on the control plates 3 correspond sequentially to the water spray nozzles 12 of the nozzle housing 1. When the water flow decreases, the turntable 32 drives the control plates 3 to rotate, so that the smaller diameter water spray holes 31 switch to the position corresponding to the water spray nozzles 12, thereby automatically reducing the size of the water spray holes 31, thus maintaining the water flow pressure and avoiding the impact of reduced water flow on the irrigation area.

[0027] Furthermore, a control groove 23 is provided on one side of the water inlet trough 13. The end of the connecting rod 34 away from the turntable 32 is placed inside the control groove 23 and fixedly connected to the middle of the bottom side of the large bevel gear 35. The connecting rod 34 is rotatably connected to the bottom inner wall of the control groove 23 through a sealed bearing. The drive rod 21 is placed inside the control groove 23, passes through the middle of the small bevel gear 36 and is fixedly connected to the small bevel gear 36. The small bevel gear 36 meshes with the large bevel gear 35.

[0028] When the water flow needs to be reduced, the servo motor 22 drives the drive rod 21 to rotate, which in turn drives the small bevel gear 36 to rotate synchronously. The small bevel gear 36 drives the large bevel gear 35 to rotate through meshing. The large bevel gear 35 then drives the connecting rod 34 to rotate, and the connecting rod 34 drives the turntable 32 and the control plate 3 to rotate. Ultimately, this causes the smaller diameter spray hole 31 to correspond with the spray nozzle 12, achieving automatic reduction in the size of the spray hole 31 when the water flow decreases. This ensures stable water spray pressure and prevents the irrigation area from shrinking. It should be noted that the sizes of the small bevel gear 36 and the large bevel gear 35 need to be matched according to the size of the control plate 3 and the number of spray holes 31.

[0029] Furthermore, the sidewall of the water spray chamber 11 is equidistantly equipped with inverted L-shaped limiting blocks 37, the limiting blocks 37 are positioned above the water spray nozzle 12 and correspond to the water spray nozzle 12, and the control plate 3 is slidably connected to the limiting blocks 37.

[0030] When the regulating mechanism reduces the water flow and drives the control plate 3 to rotate through the linkage structure, the limit block 37 can guide the control plate 3 to slide smoothly, so that the spray holes 31 of different diameters on the control plate 3 are precisely aligned with the spray nozzle 12.

[0031] Furthermore, the detection assembly includes a magnet 24 and a Hall sensor 25 for detecting the rotation angle of the drive rod 21. The magnet 24 is installed in a ring at equal intervals on the outside of the drive rod 21. The Hall sensor 25 is fixedly connected to the inner wall of the top of the control groove 23. The magnet 24 corresponds to the Hall sensor 25. A controller 26 is provided on the upper side of the nozzle housing 1 near the servo motor 22.

[0032] When a reduction in water flow is required, the controller 26 sends a command to the servo motor 22, which drives the drive rod 21 to rotate. During the rotation of the drive rod 21, the outer magnet 24 rotates synchronously with it. The Hall sensor 25 senses the position change of the magnet 24 and converts the rotation angle of the drive rod 21 into an electrical signal, which is then fed back to the controller 26. The controller 26 determines the extent of the reduction in water flow based on this signal and ensures, through a preset program, that the rotation of the drive rod 21 synchronously drives the small bevel gear 36, the large bevel gear 35, the connecting rod 34, and the turntable 32 to rotate, causing the control board 3 to switch to the small-sized spray nozzle 31 with a matching diameter.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
