Description

Technical Field

[0001] This utility model relates to the technical field of water and fertilizer irrigation equipment, specifically an automatic water and fertilizer irrigation equipment for vegetable cultivation. Background Technology

[0002] Water-fertilizer irrigation is a technology that dissolves fertilizer in water and simultaneously provides water and nutrients to crops through an irrigation system. Its core is the precise adjustment of nitrogen, phosphorus, potassium, and other element concentrations according to the crop's growth stage requirements, delivering them directly to the roots via drip irrigation, sprinkler irrigation, or other equipment. This method reduces fertilizer volatilization and loss. Combined with an intelligent control system, it can monitor soil moisture and crop growth in real time, dynamically adjusting the irrigation volume and fertilizer solution ratio. Suitable for greenhouses, orchards, and other scenarios, it promotes uniform crop growth and shortens the growth cycle, making it a key technology for efficient modern agricultural planting. However, existing water-fertilizer irrigation equipment still has certain problems in use:

[0003] For example, a crop pre-planting water and fertilizer spraying device with application number 202420340937.2 has the following technical solution: it includes a first water inlet pipe and a second water inlet pipe. The end of the first water inlet pipe is fixedly installed with a second threaded pipe. When using the crop pre-planting water and fertilizer spraying device, the cooperation between the first water inlet pipe and the second water inlet pipe can increase the second water inlet pipe according to the area of ​​the planting ground, so that the spraying length can be extended, thereby making it convenient to spray the planting ground completely at one time. However, traditional devices mostly adopt a single pole base or simple counterweight design. The contact area between the base and the ground is small. Under the condition of high spraying pressure, the backflow of water can easily cause the device to shake. Especially in the windy outdoor environment, the risk of tipping is high. In addition, the height of the device is mostly a fixed structure, which cannot be adapted to different crop growth stages.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing water and fertilizer irrigation equipment. Utility Model Content

[0006] The purpose of this invention is to provide an automatic irrigation device for vegetable cultivation, in order to solve the problems mentioned in the background art, such as the unstable spray structure and the inability to adjust to the height of vegetables.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

The outlet is connected to a main pipeline, which is distributed and connected to several branch pipelines in the vegetable cultivation field. Vertical pipes are connected at equal intervals above each branch pipeline. A support frame is fitted around the outside of each branch pipeline and fixed to the outside of the branch pipeline by a ring-shaped fixing frame. A channel is opened in the middle of the support frame, and a flexible hose is connected above the vertical pipe, passing through the middle of the support frame. A spray head is installed above the support frame, and the spray head has an adjustable structure according to the vegetable cultivation height.

[0009] Preferably, a drive motor is fixedly installed on the top of the water and fertilizer tank, and the drive motor is electrically connected to the controller. A rotating rod is connected to the bottom output end of the drive motor, and several stirring rods are fixedly installed on the outside of the rotating rod.

[0010] Using the above technical solution, the drive motor drives the rotating rod and stirring rod to rotate, which can fully mix the water and fertilizer in the water-fertilizer tank, avoiding uneven fertilizer concentration caused by fertilizer sedimentation. Compared with manual stirring, the stirring efficiency is improved, and the stirring time is precisely controlled by the controller to ensure the accuracy of fertilizer solution ratio, laying the foundation for uniform irrigation in the future.

[0011] Preferably, a solenoid valve is installed at the connection between the discharge port and the main pipeline, and the solenoid valve is controlled by a controller.

[0012] Using the above technical solution, the solenoid valve can be automatically switched on and off by the controller, which can accurately control the flow rate of fertilizer solution from the outlet into the main pipeline. The on / off status of the solenoid valve can be fed back to the controller in real time, which facilitates remote monitoring of the irrigation progress and avoids over- or under-irrigation due to human error.

[0013] Preferably, the support frame is provided with a chassis at the bottom, and three legs are fixedly connected to the bottom of the chassis, with the bottom of the legs having sharp points that are inserted into the soil to form a fixed structure with the ground.

[0014] By adopting the above technical solution, the base and three sharp legs at the bottom of the support frame are inserted into the soil, which improves the wind load resistance. Even in environments with high spray pressure or windy conditions outdoors, the device can be prevented from shaking or tipping over, ensuring the stable operation of the branch pipes and spray heads.

[0015] Preferably, an annular fixing frame is fixedly installed on the upper surface of the chassis, and the annular fixing frame includes an annular sliding rod.

[0016] Using the above technical solution, the ring-shaped fixing frame on the chassis is fixed to the branch pipes through the ring-shaped sliding rod, which improves the stability of the branch pipes and avoids the misalignment of the spray range caused by vibration or external force displacement of the branch pipes, ensuring that water and fertilizer are evenly covered in the cultivation area.

[0017] Preferably, the annular fixing frame is C-shaped and has a hollow internal structure, and the annular slide rod slides on the annular fixing frame to form a pipe fixing structure.

[0018] By adopting the above technical solution, the hollow structure of the C-type ring-shaped fixing bracket allows the ring slide bar to slide flexibly, enabling fast installation and adjustment and improving installation convenience.

[0019] Preferably, a threaded sleeve is fixedly installed on the upper surface of the support frame, and a threaded rod is threadedly connected above the threaded sleeve. The threaded rod has a hollow structure, and a spray head is installed at the top of the threaded rod.

[0020] Using the above technical solution, the threaded sleeve on the support frame is threadedly connected to the hollow threaded rod. Rotating the threaded rod can adjust the height of the spray head. The hose runs through the inside of the threaded rod and is connected to the spray head, which can adapt to different growth heights of vegetables from seedling to maturity, without the need for frequent replacement of the spray device.

[0021] Compared with the prior art, the beneficial effects of this utility model are: this automatic water and fertilizer irrigation equipment for vegetable cultivation...

[0022] 1. Stable support and flexible adaptation ensure irrigation reliability: The support frame is firmly fixed to the ground by the chassis and three legs, with strong wind resistance and anti-tipping ability. The ring-shaped fixing frame is easy to install, and the threaded adjustment structure allows the height of the sprinkler head to be adjusted according to the growth of vegetables, solving the problems of poor stability and inability to adapt to crop height of traditional devices. The spraying stability is improved, and it is suitable for full coverage of the vegetable growth cycle.

[0023] 2. Automatic mixing and precise control improve irrigation efficiency: The drive motor drives the stirring rod to achieve automatic mixing of water and fertilizer. The solenoid valve precisely regulates the flow rate through the controller, reducing manual intervention and improving efficiency compared to traditional manual irrigation. It also increases the utilization rate of fertilizer solution and avoids fertilizer waste and environmental pollution. Attached Figure Description
