Description

Technical Field

[0001] This utility model relates to the field of drip irrigation equipment technology, specifically to an integrated drip irrigation device for alfalfa planting using both water and fertilizer. Background Technology

[0002] Alfalfa, a perennial herbaceous plant belonging to the genus *Alfalfa* in the legume family, is characterized by its well-developed taproot, multi-branched stems, and trifoliate compound leaves. Its flowers are small and densely packed in racemes, and its fruit is a pod. With its rich protein and other nutrients, alfalfa is a highly sought-after premium forage, suitable for various livestock farming.

[0003] In alfalfa irrigation, drip irrigation is now widely used, and the accompanying fertigation equipment is mostly fixed, meaning the equipment is stationary and delivers fertilizer to the entire field. However, this fertilization method has significant drawbacks: for fields far from the equipment, fertilizer must be transported over long distances through the main drip irrigation network. After the drip irrigation operation is completed, a large amount of fertilizer remains in the main pipeline between the equipment and the irrigated field, resulting not only in direct fertilizer waste but also in lower actual fertilizer absorption by the crops, thus affecting their growth. Utility Model Content

[0004] This utility model provides an integrated water and fertilizer drip irrigation device for alfalfa planting to solve the following problems of existing fixed integrated water and fertilizer equipment mentioned in the background art: For farmland far from the equipment, fertilizer needs to be transported over long distances through the drip irrigation network main pipe. After the water and fertilizer drip irrigation operation is completed, a large amount of fertilizer will remain in the main pipe between the equipment and the irrigated farmland, which not only causes direct waste of fertilizer, but also leads to a lower actual amount of fertilizer absorbed by the crops, affecting the growth effect.

[0005] To address the existing problems, this utility model provides an integrated drip irrigation device for alfalfa planting, comprising a support plate, a wheel frame fixedly connected to the bottom end of the support plate, a wheel axle fixedly connected to the lower end of the wheel frame, and walking wheels rotatably connected to both ends of the wheel axle. A stirring assembly is provided on the upper rear surface of the support plate, and a delivery pump and a generator are sequentially arranged on the support plate in front of the stirring assembly.

[0006] The mixing assembly includes a mixing tank fixedly connected to a support plate. A mixing shaft is arranged along the axis inside the mixing tank, and a mixing paddle is fixedly connected to the mixing shaft. The upper end of the mixing shaft is fixedly connected to the output shaft of a drive motor fixedly installed on the top cover of the mixing tank. A hopper communicating with the interior of the mixing tank is fixedly connected to the top cover of the mixing tank. The bottom end of the mixing tank is connected to the inlet of a delivery pump through a delivery pipe. A water inlet pipe is fixedly connected to the side wall of the mixing tank near the top. A connecting lug is fixedly connected to the upper surface of the front end of the support plate. The connecting lug is hinged to the rear end of the traction frame. A connecting plate is rotatably connected to the front end of the traction frame.

[0007] Furthermore, a first solenoid valve is installed on the delivery pipe, and a second solenoid valve is installed on the water inlet pipe.

[0008] Furthermore, the drive motor, delivery pump, generator, first solenoid valve, and second solenoid valve are all electrically connected to the controller.

[0009] Furthermore, the outlet of the delivery pump is fixedly connected to an outlet pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model connects the device to an external traction device via a traction frame and connecting plate. Utilizing the cooperation of the walking wheels, axles, and wheel frame, it can move the bearing plate and upper components to the alfalfa field to be irrigated. Then, the drive motor of the mixing component rotates the mixing shaft and mixing paddle, allowing the fertilizer and water to be fully mixed in the mixing tank, forming a uniform water-fertilizer solution. This solution is then connected via a delivery pump and an outlet pipe to the drip irrigation main pipe of the alfalfa field to be irrigated. The fertilizer solution mixes with the flowing water in the drip irrigation main pipe, achieving both fertilization and irrigation of the alfalfa. This ensures balanced nutrient absorption by the alfalfa, avoiding the fertilizer residue problem in the main pipeline caused by long-distance transport in traditional fixed equipment, maximizing the fertilizer's effect on the alfalfa, and improving fertilizer utilization.

[0012] 2. The controller of this utility model enables centralized control of components such as the drive motor, delivery pump, first solenoid valve, and second solenoid valve, reducing labor intensity; secondly, the generator provides stable power support, ensuring continuous operation of the device when working in different locations in the field.

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.

[0018] Please see Figure 1-3 A drip irrigation device for alfalfa planting that integrates water and fertilizer includes a support plate 1, a wheel frame 2 fixedly connected to the bottom end of the support plate 1, a wheel axle 3 fixedly connected to the lower end of the wheel frame 2, and walking wheels 4 rotatably connected to both ends of the wheel axle 3. A stirring component 5 is provided on the upper rear surface of the support plate 1, and a delivery pump 6 and a generator 7 are arranged sequentially on the support plate 1 in front of the stirring component 5.

[0019] The mixing assembly 5 includes a mixing tank 501 fixedly connected to the support plate 1. A mixing shaft 502 is arranged along the axis inside the mixing tank 501. A mixing paddle 503 is fixedly connected to the mixing shaft 502. The upper end of the mixing shaft 502 is fixedly connected to the output shaft of the drive motor 504 fixedly installed on the top cover of the mixing tank 501. A hopper 505 communicating with the inside of the mixing tank 501 is fixedly connected to the top cover of the mixing tank 501.

[0020] The bottom end of the mixing tank 501 is connected to the inlet of the delivery pump 6 through the delivery pipe 8, and the side wall of the mixing tank 501 near the top is fixedly connected to the water inlet pipe 9.

[0021] A connecting ear 14 is fixedly connected to the upper front surface of the bearing plate 1. The connecting ear 14 is hinged to the rear end of the traction frame 15. A connecting plate 16 is rotatably connected to the front end of the traction frame 15.

[0022] The first solenoid valve 11 is installed on the delivery pipe 8, and the second solenoid valve 10 is installed on the inlet pipe 9.

[0023] Among them, the drive motor 504, the delivery pump 6, the generator 7, the first solenoid valve 11, and the second solenoid valve 10 are all electrically connected to the controller 12.

[0024] The outlet of the delivery pump 6 is fixedly connected to the outlet pipe 13.

[0025] Working Principle: First, the device is connected to an external traction device via the traction frame 15 and connecting plate 16. Utilizing the cooperation of the walking wheels 4, axle 3, and wheel frame 2, the bearing plate 1 and its upper components can be moved to the alfalfa field to be irrigated, enhancing the device's flexibility. Then, fertilizer is added to the mixing tank 501 via the hopper 505. The inlet pipe 9 and outlet pipe 13 are both connected to the main drip irrigation pipe of the alfalfa field to be irrigated, with the inlet pipe 9 connected to the main drip irrigation pipe before the outlet pipe 13. Then, the controller 12 controls the second solenoid valve 10 to open, allowing water from the main drip irrigation pipe to be delivered to the mixing tank 501 to a suitable level before closing the second solenoid valve 10. Subsequently, the controller 12 starts the drive motor 504, driving the mixing shaft 502 and the mixing paddle 503 on the mixing shaft 502 to rotate, ensuring the fertilizer and water are fully mixed in the mixing tank 501 to form a nutrient solution. Once the solution is prepared, the controller 12 shuts off the drive motor 504 and simultaneously opens the first solenoid valve 11, starting the delivery pump 6. The water-fertilizer solution in the mixing tank 501 is then pumped into the delivery pump 6 through the delivery pipe 8. After being pressurized by the delivery pump 6, it is delivered to the drip irrigation main pipe through the outlet pipe 13. The main pipe then delivers the fertilizer solution and water together to the drip irrigation capillary tubes, achieving precise irrigation and fertilization of alfalfa.

[0026] Throughout the process, generator 7 provides power to drive motor 504, delivery pump 6, controller 12, first solenoid valve 11, and second solenoid valve 10. Furthermore, the device can be moved on field roads using the walking wheels 4 via the traction frame 15 and connecting plate 16 in conjunction with external traction equipment, changing its operating position and moving to alfalfa fields requiring drip irrigation. This overcomes the problem of fertilizer residue in the main pipeline caused by previous fixed fertigation devices.
