Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry breeding equipment, and in particular to an omnidirectional adjustable cloud fogger for livestock farms. Background Technology

[0002] Environmental control in piglet rearing is a core factor affecting survival rate, and existing environmental control methods face specific challenges: 1. The contradiction between temperature and humidity: Piglets have weak thermoregulation capabilities (the critical temperature for newborn piglets is 34℃), and traditional spray cooling can easily cause cold stress, while disinfection requires maintaining a humidity level of >70% to prevent the spread of respiratory pathogens (such as mycoplasma); 2. Disinfection safety risks: Fixed spray devices are difficult to avoid the piglet resting area, and high concentrations of disinfectant residue can cause corneal damage; 3. Pathogen hiding places: Areas such as suckling pens and corners of incubators become breeding grounds for pathogens such as Salmonella due to the blind spots in equipment adjustment.

[0003] Existing misting machines have the following problems: 1. Fixed spray booms or simple swing mechanisms cannot cover dead corners in three-dimensional space (such as corners at the top of the pen), resulting in uneven disinfection / cooling and failure to cover the three-dimensional space of nursing pens: the disinfection coverage rate of the heat lamp area (Salmonella enrichment area) above 1.8m from the ground is <35%. 2. Wheeled trolley-type equipment relies on manual steering, making it difficult to accurately position and operate in densely populated breeding areas, and unable to enter the limiting pen passage of the farrowing pen (standard width 0.65m); 3. The droplet size (>150μm) generated by conventional centrifugal nozzles is prone to settling, failing to form a continuous suspended "mist effect", affecting the efficiency of pathogen killing.

[0004] The aforementioned problems stem from the lack of three major technological breakthroughs at the equipment structure level: precise three-dimensional positioning, aerosol-based collaborative optimization, and dynamic obstacle avoidance capabilities. There is an urgent need for a dedicated solution tailored to the biological characteristics of piglets (weak thermoregulation and high susceptibility to pathogens). Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an omnidirectional adjustable cloud fogger for aquaculture farms.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses an omnidirectional adjustable misting machine for aquaculture farms, comprising: a remote-controlled mobile chassis; a water storage unit and a fluid pressurization device fixed to the top of the remote-controlled mobile chassis; and two sets of spraying mechanisms symmetrically arranged on the top of the remote-controlled mobile chassis. Each spraying mechanism includes: a fixed base cylinder, the bottom of which is connected to a hinged support hinged to the remote-controlled mobile chassis via a linear actuator; a pitch adjustment cylinder coaxially sleeved inside the fixed base cylinder and rotated via a rotary joint; a universal hinge frame rigidly connected to the top of the pitch adjustment cylinder and provided with a U-shaped fork and a lateral lug; two first-stroke adjustable cylinders arranged in parallel and respectively hinged to the lug and the U-shaped fork on the top of the fixed base cylinder; an airflow acceleration duct hinged to the lateral lug via a second-stroke adjustable cylinder; a turbine fan integrated into the air inlet end of the airflow acceleration duct; an annular spray manifold coaxially fixed to the air outlet end face of the airflow acceleration duct; and multiple high-pressure atomizing nozzles evenly distributed circumferentially along the annular spray manifold, with the spray axis of each nozzle forming an outward inclination angle of 15°-45° with the central axis of the duct.

[0008] As a preferred technical solution of this utility model, the inner wall of the pitch adjustment cylinder is fixedly connected to a rotating shaft, and the outer wall of the fixed bottom cylinder is fitted with a bearing to form a rotation linkage structure.

[0009] As a preferred technical solution of this utility model, the cylinder end of the second stroke adjustable cylinder is hinged to the lateral lug of the universal hinge frame, and the piston rod end is connected to the side wall of the airflow acceleration duct through a ball joint.

[0010] As a preferred technical solution of this utility model, the annular spray manifold is detachably fixed to the end face of the airflow acceleration duct by a quick-release clamp.

[0011] As a preferred embodiment of this utility model, the linear actuator is a hydraulic strut or an electric push rod, with its base hinged to the remote-controlled moving chassis and its output end hinged to the bottom surface of the fixed bottom cylinder.

[0012] As a preferred technical solution of this utility model, the inlet of the fluid booster device is connected to the water storage unit through a flexible water supply pipe, and the outlet is connected to the annular spray manifold of the two spray mechanisms through a water distribution integrated valve group.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Based on the dual-stage angle control of the pitch adjustment cylinder (fixed bottom cylinder 0-30° coarse adjustment + first stroke adjustable cylinder -45° to +80° fine adjustment), it can dynamically avoid the breastfeeding area and the insulated box (>0.8m safe distance), making the disinfectant accidental spray rate zero and eliminating the risk of disinfectant corneal damage.

[0015] 2. By accelerating the synergistic effect of the airflow duct and the annular spray manifold, a continuous suspended mist is formed, with the droplet size refined to 80-120μm and the suspension time extended by 3 times;

[0016] 3. The remote-controlled chassis responds to commands to move at speeds from 0 to 5 km / h; the multi-mechanism linkage control system achieves synchronized flow of the dual spray arms, increasing the efficiency of a single operation by 40% and reducing manual intervention by 80%.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] Example 1, such as Figure 1-4As shown, this utility model provides an omnidirectional adjustable misting machine for livestock farms. The overall structure consists of a remote-controlled mobile chassis 1 supporting the entire machine, equipped with four-wheel drive electric wheels, and a minimum turning radius of 0.35m (suitable for narrow passageways in pigsties). The water storage unit 2 uses a 500L food-grade PE water tank, which is bolted to the upper part of the chassis 1. The fluid pressurization device 4 uses a plunger pump (maximum output pressure 0.8MPa), and its inlet is connected to the outlet valve at the bottom of the water storage unit 2 via a flexible water supply pipe 21.

[0026] The operating logic of the spraying mechanism 3: The bottom of the fixed base cylinder 31 is welded with a hinge seat, which is connected to the hinge support 33 of the chassis 1 through a pin shaft to achieve a fixed installation with an initial tilt angle of 15°.

[0027] The lower end of the linear actuator 32 is hinged to the mounting platform 11 of the chassis 1, and the upper end is hinged to the bottom surface of the fixed base cylinder 31, driving the overall pitch angle to be adjusted between 0° and 30°. The pitch adjustment cylinder 34 is fitted inside the fixed base cylinder 31: the inner wall is fixed to the rotating shaft 341, forming a rotating pair with the outer ring bearing 311 of the fixed base cylinder 31; the top flange is connected to the universal hinge frame 35; two first stroke adjustable cylinders 36 are arranged in parallel: the cylinder body end is hinged to the ear plate 312 on the top of the fixed base cylinder 31; the piston rod end is hinged to the U-shaped fork 351 of the universal hinge frame 35; driving the spray unit to pitch between -45° (downward to avoid piglets) and +80°.

[0028] The atomization system works as follows:

[0029] 1. The cylinder body end of the second-stroke adjustable cylinder 37 is hinged to the lateral lug 352 of the universal hinge frame 35, and the piston rod end is connected to the side wall of the airflow acceleration duct 38 through the ball joint 381 to achieve horizontal ±180° rotation.

[0030] 2. The turbine fan 39 is embedded in the air inlet of the air duct 38, generating a high-speed airflow of 12m / s;

[0031] 3. The annular spray manifold 5 is fixed to the air outlet of the air duct 38 by quick-release clamps 51. Eight high-pressure atomizing nozzles 6 are evenly distributed around its circumference, and the spray axis of each nozzle is inclined outward at a 15° angle to the central axis of the air duct. The sprayed 90μm-sized droplets are sheared by the airflow to form a cloud of mist with a diffusion radius of up to 8m.

[0032] Example 2, based on Example 1, enhances the aerosol mixing performance:

[0033] The outward tilt angle of the nozzle 6 in the annular spray manifold 5 is increased to 25°, causing the mist flow to form a swirling vortex with the central airflow of the air duct 38. A spiral guide vane (not shown) is installed inside the manifold to accelerate the pre-swirl of the liquid.

[0034] The number of blades in the turbine fan 39 was increased to 7, and the blade tilt angle was adjusted to 65°. A guide ring groove was added to the inner wall of the air duct 38, increasing the wind speed to 15 m / s. The droplet size was reduced to 80 μm, and the suspension time was extended to 12 minutes.

[0035] The stroke of the second-stroke adjustable cylinder 37 is increased to 200mm, expanding the horizontal rotation range of the air duct 38 to ±210°. The ball joint 381 is replaced with a universal joint structure, improving the corner pointing accuracy of the parking space.

[0036] Example 3 improves maintainability based on Example 1:

[0037] The quick-release clamp 51 uses a cam locking structure made of 304 stainless steel, with a disassembly and assembly time of ≤16 seconds (compared to 120 seconds for traditional bolt-type clamps). The annular spray manifold 5 has a 316L stainless steel filter screen embedded in its inner cavity to prevent the nozzles 6 from clogging.

[0038] The integrated water distribution valve group 22 is equipped with dual independent solenoid valves (flow rate adjustable from 0-10L / min), and the disinfection / humidification mode can be switched via the chassis 1 remote control.

[0039] The flexible water supply pipe 21 is made of four-layer steel wire reinforced PVC pipe (pressure resistance 1.2MPa), which can withstand frequent bending.

[0040] Corrugated dust covers are added to the piston rods of the first-stroke adjustable cylinder 36 and the second-stroke adjustable cylinder 37 to prevent dust from entering the pigsty.

[0041] This invention relates to an omnidirectional adjustable misting machine for livestock farms. It achieves mobile coverage via a remote-controlled chassis and utilizes a three-stage adjustment mechanism for three-dimensional spatial positioning. The innovative combination of a pneumatic turbine and tilting nozzles allows droplets to form micron-sized mist under airflow shearing, making it particularly suitable for disinfection, cooling, and humidification needs in large spaces of livestock farms. The symmetrical layout further enhances operational coverage efficiency.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
