Abstract
Description
Technical Field
[0001] This utility model belongs to, but is not limited to, the field of planting technology, and particularly relates to a high-pressure rotary atomizing spraying device for orchard application. Background Technology
[0002] In the daily management of orchards, pest and disease control is a crucial aspect, and pesticide spraying is one of the main methods of pest and disease control. Traditional orchard pesticide application devices have many limitations and can no longer meet the needs of modern orchards for efficient and precise pesticide application, as detailed below:
[0003] Traditional pesticide application devices typically mix pesticide and water before spraying. However, this method has significant drawbacks: low spraying efficiency. Because the pesticide and water are mixed before spraying, the mixture needs to be mixed again after spraying, which greatly increases the interruption time in the spraying process and reduces the overall spraying efficiency.
[0004] Uneven spraying: Traditional nozzles have a fixed spray angle, making it difficult to achieve uniform coverage of every corner of the orchard. This results in some areas having excessively high pesticide concentrations, potentially causing phytotoxicity, while other areas have insufficient pesticide concentrations, failing to effectively control pests and diseases. Inconvenient operation: Traditional devices typically require manual control of the nozzles and spray direction, making operation cumbersome and labor-intensive. This method is particularly inefficient in large orchards.
[0005] Poor adaptability: The planting density, tree height, and pest and disease conditions vary in different orchards, making it difficult for traditional equipment to be flexibly adjusted according to actual needs, resulting in poor pesticide application effects. Utility Model Content
[0006] To address the problems existing in the prior art, this utility model provides a high-pressure rotary atomizing spraying device for orchard pesticide application.
[0007] This utility model is implemented as follows: a high-pressure rotary atomizing spraying device for orchard pesticide application. The device includes: a liquid tank, a stirring device, a high-pressure pump, a rotating arm, an atomizing nozzle, and an intelligent control module. The rotating arm can rotate 360° horizontally, and the pitch angle of the nozzle is adjustable.
[0008] The liquid tank is connected to a high-pressure pump via a pipeline, and the output end of the high-pressure pump is connected to an atomizing nozzle on the rotating arm via a rotary joint; a stirring device is installed inside the liquid tank, and the output end of the high-pressure pump is connected to the nozzle via a rotary joint; the intelligent control module is connected to the rotating arm and the atomizing nozzle.
[0009] Furthermore, the intelligent control module is used to adjust the spraying pressure, flow rate, and rotation parameters in real time.
[0010] Furthermore, the stirring device is driven by an independent motor, and the stirring speed is adjustable from 0 to 300 rpm to prevent the medicine solution from separating.
[0011] The rotary joint adopts a sealed bearing design to ensure no leakage under high pressure.
[0012] Furthermore, the atomizing nozzle is a dual-fluid nozzle, with a high-pressure airflow channel and a liquid medicine channel inside the nozzle. The airflow pressure is 0.5-0.8MPa, and the liquid medicine pressure is 8MPa. Micron-level atomization is achieved through gas-liquid mixing. The atomized particle size is ≤100μm, and the droplet uniformity is ≥90%, effectively covering the back of fruit tree leaves and hidden areas.
[0013] Furthermore, the intelligent control module includes:
[0014] PLC controller: integrates pressure sensor, flow meter and touch screen to collect spray pressure, flow and rotating arm angle data in real time;
[0015] Automated adjustment: The spraying pressure is automatically adjusted to 5-8 MPa, the flow rate to 5-10 L / min, and the rotation speed to 30-60 rpm based on the height of the fruit trees and the density of the canopy.
[0016] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this utility model are as follows:
[0017] High efficiency and energy saving: Mixing and spraying at the same time reduces operation interruption, and a single unit can cover an area of up to 50 acres per day.
[0018] Uniform coverage: 360° rotation + pitch adjustment increases the adhesion rate of the pesticide by 40% and reduces the need for repeated spraying.
[0019] Precise control: The intelligent adjustment system adapts to different fruit tree shapes, reducing pesticide use by 20%.
[0020] Easy to operate: One-click start / stop, remote monitoring of equipment status, and reduced labor costs. Attached Figure Description
