Description

Technical Field

[0001] This utility model specifically relates to an automatic irrigation device for crops, belonging to the field of irrigation technology. Background Technology

[0002] Crop irrigation is a crucial aspect of agricultural production, directly impacting crop yield and quality. In modern agriculture, a sufficient and appropriate water supply not only ensures healthy crop growth but also improves land utilization and economic efficiency.

[0003] However, current crop irrigation devices are usually fixed and cannot be adjusted, resulting in a small irrigation coverage area that is difficult to meet the irrigation needs of large areas of farmland. In large-scale farmland that often covers hundreds of acres, the irrigation area of ​​a single fixed irrigation device can easily create a large number of irrigation blind spots. To solve this problem, farmers have to invest a lot of time and manpower to frequently move irrigation equipment or continuously add devices, which undoubtedly increases production costs and labor intensity.

[0004] In view of this, this application proposes an automatic irrigation device for crops to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an automatic irrigation device for crops. Through the design of the irrigation mechanism, a first motor drives a rotating shaft to engage with an adjusting gear set, which in turn drives a fixed frame to allow two sets of adjusting pipes to rotate flexibly around the axis, thereby enabling the nozzles to achieve multi-angle adjustment. After the second motor starts, the driving gear engages with the outer gear ring, which, through the center plate and the vertical plate, drives the adjusting pipes to rotate horizontally to adjust the irrigation direction. The angle adjustment and steering adjustment components work together to significantly improve irrigation efficiency and coverage area, thus solving the problems mentioned in the background art.

[0006] An automatic irrigation device for crops includes: an irrigation mechanism, comprising an angle adjustment component and a steering adjustment component; the angle adjustment component includes two sets of upright plates, each of which has a set of rotatable angle-adjustable adjustment pipes on both sides, and a nozzle for spray irrigation is installed at the front end of the adjustment pipes; two sets of meshing adjustment gears are provided between the two sets of upright plates; the steering adjustment component includes a central plate fixed below the two sets of upright plates, which can rotatably adjust the spray direction of the nozzles, and an external gear ring is installed on the outer side of the central plate; a drive gear is meshed on one side of the external gear ring; and a rotary joint is installed in the middle of the central plate.

[0007] In a preferred embodiment, a rotating shaft is installed in the middle of the adjusting gear, and the two ends of the rotating shaft are respectively rotatably connected to two sets of upright plates. A motor is installed above the rear upright plate, and the output shaft of the motor is connected to one of the sets of rotating shafts.

[0008] In a preferred embodiment, a fixing frame is provided on the outer side of the adjusting gear, and the rear end of the adjusting tube is fixedly connected to the rotating shaft through the fixing frame.

[0009] In a preferred embodiment, a fixed cylinder is provided below the center plate, the upper end of the fixed cylinder is rotatably connected to the center plate, the rotating part of the rotary joint is connected to the center plate, a connecting pipe is installed at the upper end of the rotary joint, and the connecting pipe is connected to two sets of adjusting pipes through two sets of transmission pipes respectively.

[0010] In a preferred embodiment, a fixing plate is installed on one side of the fixing cylinder, and a second motor is installed above the fixing plate. The output shaft of the second motor is connected to the drive gear.

[0011] In a preferred embodiment, a water tank is installed below the fixed cylinder, and a water pump is installed on one side above the water tank. The water pump is connected to the lower end of the rotary joint through an output pipe and to the inside of the water tank through an extraction pipe.

[0012] In a preferred embodiment, a water inlet pipe is installed on the top of the water tank, and a drain valve is installed on the lower back of the tank.

[0013] As a preferred embodiment, a controller is installed on one side of the front of the water tank, and the controller is electrically connected to motor 1 and motor 2, both of which are stepper motors.

[0014] Beneficial effects:

[0015] 1. By designing an angle adjustment component, when the No. 1 motor is running, the rotating shaft drives one set of adjustment gears to rotate. Through the meshing transmission between the gears, the other adjustment gear also rotates synchronously. This linkage mechanism drives the connected fixed frame, causing the two sets of adjustment pipes to rotate flexibly around the rotating shaft. As the angle of the adjustment pipe changes, the sprinkler head installed at the end also adjusts the spray angle accordingly, thereby achieving multi-angle free adjustment and effectively expanding the irrigation range.

[0016] 2. By designing a steering adjustment component, after the No. 2 motor starts, the drive gear and the external gear ring form a highly efficient meshing transmission. The rotation of the external gear ring is transmitted to the vertical plate through the central plate, thereby driving the adjustment pipe to rotate horizontally and flexibly change the spray direction. When the central plate rotates, it simultaneously drives the rotating part of the rotary joint to rotate. This design ensures both the steering of the adjustment pipe and the stable transmission of spray water, avoiding the impact of pipe twisting on water flow. The steering adjustment component and the angle adjustment component work together to reduce the number of irrigation equipment required and eliminate the need for frequent device relocation, enabling comprehensive irrigation of the area surrounding the device. This significantly expands the irrigation range and improves irrigation efficiency and coverage area. Attached Figure Description

[0027] Please see Figures 1-4 As shown, a fixed cylinder 21 is provided below the center plate 23. The upper end of the fixed cylinder 21 is rotatably connected to the center plate 23. The rotating part of the rotary joint 27 is connected to the center plate 23. A connecting pipe 28 is installed on the upper end of the rotary joint 27. The connecting pipe 28 is connected to two sets of adjusting pipes 12 through two sets of transmission pipes 15 respectively. The upper end of the fixed cylinder 21 is rotatably connected to the center plate 23. With the rotating part of the rotary joint 27 connected to the center plate 23, it ensures that the center plate 23 can drive the vertical plate 11 and the adjusting pipe 12 to rotate flexibly and adjust the spray direction. It also ensures that the water flow can be stably and continuously transmitted from the water tank 3 to the adjusting pipe 12 and the nozzle 13 during the rotation process.

[0028] Please see Figures 1-4 As shown, a fixing plate 22 is installed on one side of the fixing cylinder 21, and a second motor 25 is installed above the fixing plate 22. The output shaft of the second motor 25 is connected to the drive gear 24.

[0029] Please see Figures 1-4 As shown, a water tank 3 is installed below the fixed cylinder 21, and a water pump 7 is installed on one side above the water tank 3.

When the center plate 23 rotates, it can drive the rotating part of the rotary joint 27 to rotate. The design of the rotary joint 27 ensures stable water flow transmission when the center plate 23 rotates, avoiding pipe twisting that affects water supply. The angle adjustment and the direction adjustment work together to cover the surrounding area, significantly expanding the irrigation range and improving irrigation efficiency.
