Description

Technical Field

[0001] This invention relates to the field of agricultural automated spraying technology, specifically to an automated mist spraying system for orchards and its usage method. Background Technology

[0002] Currently, high-pressure spraying or mist spraying equipment is commonly used for pest and disease control in orchards. Traditional systems typically consist of a pesticide tank, filter, high-pressure pump, distributor, delivery pipeline, and nozzles.

[0003] However, after shutdown, the residual liquid in the pipeline cannot be effectively drained, causing the liquid to crystallize and dry at the nozzles, valves, or pipe walls, resulting in blockages and severely affecting subsequent use. Currently, to solve the above problems, some equipment is equipped with an air compressor or purging device to blow out the residual liquid with compressed air after shutdown. However, this solution increases system complexity, energy consumption, and cost.

[0004] Therefore, there is an urgent need for an automated mist spraying system for orchards that is simple in structure, requires no external purging equipment, and has self-draining and self-cleaning capabilities. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide an automated mist spraying system and its usage method that does not rely on an air compressor, can automatically drain residual liquid in the pipeline after shutdown, has a reliable structure, and is adaptable to the layout of fruit trees.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an automated mist spraying system for orchards, comprising a liquid supply unit, a filtration unit, a spraying host and a liquid diversion unit arranged in sequence; The liquid diversion unit includes an infusion pipe assembly set according to the location of the fruit trees in the orchard and an automatic draining mechanism located at the end of the infusion pipe assembly. The infusion tube assembly is also connected to several atomizing nozzles that are positioned to match the fruit tree location. The automatic drainage mechanism discharges the residual pesticide solution in the infusion tube assembly when the spraying host stops.

[0007] Preferably, the automatic draining mechanism includes a valve body and a valve core elastically disposed within the valve body; When the spraying unit is started, the valve core overcomes the elastic force and closes the valve body under the pressure of the spray solution; When the pressure is released, the valve core resets, and the residual liquid is discharged through the valve body.

[0008] Preferably, the liquid distribution unit further includes a water distributor, the liquid outlet of the spraying host is connected to the water distributor, and the water outlet of the water distributor is connected to the infusion pipe assembly; The infusion tubing group consists of multiple infusion branches connected in parallel with the water distributor. The automatic drainage mechanism has multiple sets, each located at the lowest point of the multiple infusion branches.

[0009] Preferably, the atomizing nozzle is an adjustable nozzle, whose spray angle, flow rate, and atomized particle size are adjusted according to the canopy structure of the fruit tree.

[0010] Preferably, the filtration unit is a group of multiple filter cartridges arranged in series, and the medicine supply unit is a medicine tank with an outlet at the bottom connected to the head filter cartridge group.

[0011] Preferably, the infusion branch is laid out along the row of fruit trees and is arranged at an angle.

[0012] Another aspect of the present invention discloses a method for using an automated mist spraying system in orchards, comprising the following steps: S1: Inject the prepared medicine into the medicine supply unit; S2: Start the spraying unit. The pesticide solution is sequentially transported to the distributor of the pesticide solution distribution unit after passing through the filter unit and pressurizing the spraying unit. S3: Pressurized liquid is distributed from the distributor to each infusion branch, pushing the valve core in the automatic drainage mechanism to overcome the elastic force and close the valve body. The liquid is then sprayed onto the fruit trees through the atomizing nozzle. S4: After the spraying operation is completed, the spraying machine is stopped, and the pressure in the infusion branch drops rapidly; S5: The valve core in the automatic drainage mechanism is reset under the action of elastic force, and the residual medicine flows to the lowest point along the inclined infusion branch; S6: Residual medication is discharged outward through the drain channel of the valve body of the automatic draining mechanism, completing the automatic emptying of the infusion tubing group.

[0013] The advantages of this invention compared with the prior art are as follows: This invention sets an elastic reset type automatic drainage mechanism at the end of the infusion branch, combined with the inclined pipeline design, and utilizes the valve core reset action and gravity to efficiently drain residual liquid and avoid crystallization blockage. This invention features a simple structure, low cost, and high reliability: eliminating components such as air compressors and solenoid valves, the system incorporates multi-stage filtration, automatic liquid drainage, and an inclined layout, significantly reducing the frequency of manual cleaning and making it easy to promote and apply.

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0017] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1 As shown, the present invention provides an automated mist spraying system for orchards, which mainly includes a liquid supply unit 1, a filtration unit 2, a spraying host 3, a water distributor 6, a liquid delivery branch 7, an atomizing nozzle 5, and an automatic liquid drainage mechanism 4.

[0020] The pesticide supply unit 1 is a pesticide tank made of corrosion-resistant plastic or stainless steel, which stores the pre-prepared pesticide solution. The bottom of the pesticide tank is provided with a liquid outlet, which is connected to the inlet of the filter unit 2 through a pipeline.

[0021] The filter unit 2 consists of two-stage filter cartridges connected in series. The multi-stage filtration design effectively prevents impurities from entering the subsequent high-pressure system and avoids clogging of the nozzles or valves.

[0022] The inlet of the spraying unit 3 is connected to the outlet of the filter unit 2, and the outlet is connected to the water distributor 6 through a high-pressure hose.

[0023] The water distributor 6 is a multi-way distribution valve structure with one inlet and multiple outlets.

[0024] In this embodiment, the outlets of the water distributor 6 correspond to multiple rows of fruit trees in the orchard, and each outlet is connected to a delivery branch 7, thereby forming multiple sets of parallel delivery branches 7.

[0025] Each infusion branch 7 is laid out along the corresponding row of fruit trees and is arranged at an angle with a slope of not less than 1% to ensure that the liquid in the pipeline can flow naturally to the lowest point at the end under the action of gravity. At the same time, multiple atomizing nozzles 5 are installed at intervals on each infusion branch 7, and their positions are aligned with the center of the trunk or canopy of the fruit tree to achieve precise application of pesticides.

[0026] The atomizing nozzle 5 is an adjustable ceramic nozzle that supports manual or electric adjustment of the spray angle, flow rate and atomized particle size. It can be flexibly configured according to the canopy density, height and growth stage of different fruit tree species such as apple, citrus and grape, to improve the adhesion rate of the liquid and reduce drift.

[0027] At the lowest point at the end of each infusion branch 7, an automatic draining mechanism 4 is installed. The automatic draining mechanism 4 includes a valve body and a valve core that is elastically disposed inside the valve body. The working principle is as follows: When the spraying host 3 is started, the liquid medicine is pressurized and delivered to the infusion branch 7. The pressure of the liquid medicine pushes the valve core to overcome its own elastic force and block the pipeline. The liquid medicine is sprayed out through the atomizing nozzle 5 to form a mist. When the spraying operation is completed and the spraying host 3 stops, the pressure in the pipeline drops rapidly. The valve core automatically resets under the action of elastic restoring force, re-locks the pipeline, and the liquid flows out through it under the action of gravity.

[0028] In specific implementation of the present invention, Includes the following steps: S1: Inject the prepared medicine into the medicine supply unit 1; S2: Start the spraying host 3. The liquid pesticide is then pressurized through the filter unit 2 and the spraying host 3 and delivered to the water distributor 6 of the liquid pesticide distribution unit. S3: Pressurized liquid is distributed from distributor 6 to each infusion branch 7, pushing the valve core in automatic drainage mechanism 4 to overcome elastic force and close the valve body. Liquid is then sprayed onto the fruit trees through atomizing nozzle 5. S4: After the spraying operation is completed, the spraying host 3 is stopped, and the pressure in the infusion branch 7 drops rapidly; S5: The valve core in the automatic drainage mechanism 4 is reset under the action of elastic force, and the residual medicine flows to the lowest point along the inclined infusion branch 7; S6: The residual medicine is discharged outward through the drain channel of the valve body of the automatic draining mechanism 4, completing the automatic emptying of the infusion tubing group.
