Description

Technical Field

[0001] This invention relates to the field of environmental control technology in livestock farming, specifically to an intelligent spray deodorization device for livestock sheds using bacterial solution. Background Technology

[0002] During large-scale livestock farming, livestock and poultry manure, urine, and feed residues will continue to ferment, producing malodorous gases such as ammonia, hydrogen sulfide, and volatile fatty acids. These gases not only pollute the farming environment but also irritate the respiratory tract of livestock and poultry, reduce their immunity and production performance, and harm the health of farmers, which does not meet the environmental protection standards for livestock farming.

[0003] Currently, deodorization methods in livestock sheds mainly include ventilation, chemical spraying, and bacterial spraying. Among these, bacterial spraying is widely used due to its advantages such as being environmentally friendly without secondary pollution, having a long-lasting deodorizing effect, and being able to degrade malodorous substances. However, existing bacterial spraying devices have several shortcomings: First, they are mostly manually controlled, requiring farmers to operate them at regular intervals, which is labor-intensive and cannot adjust spraying parameters in real time according to the concentration of malodors in the shed, easily leading to waste of bacterial solution or incomplete deodorization. Second, the spraying is uneven, with some areas being sprayed excessively, resulting in excessive humidity in the shed, while other areas are sprayed insufficiently, failing to achieve the desired deodorization effect. Third, they lack monitoring and automatic replenishment functions for residual bacterial solution, easily leading to the deodorization being interrupted when the bacterial solution is depleted and not replenished in time. Fourth, existing devices are mostly fixed installations, unable to adapt to sheds of different sizes and livestock species, resulting in poor versatility and inconvenient maintenance.

[0004] In the existing technology, such as the odor removal device for livestock breeding with authorization announcement number CN218962172U, the odor is mainly removed by the odor exhaust fan, the odor purification plate filter and the treatment agent. Although it can remove odor, it does not use the bacterial liquid spraying method and lacks intelligent control function. It cannot adjust the purification parameters in real time according to the odor concentration in the house, and the deodorization efficiency and flexibility are insufficient. The deodorization device with authorization announcement number CN219663140U, although it has the functions of being mobile and spraying, does not focus on the intelligent control of bacterial liquid spraying, and has a complex structure and limited adaptability, making it difficult to meet the high-efficiency deodorization needs of large-scale livestock farms.

[0012] A further improvement of the technical solution of the present invention is that: the bacterial liquid storage tank is made of transparent and corrosion-resistant material, and is provided with a cleaning port and a drain port. The cleaning port is used to clean the bacterial liquid storage tank regularly, and the drain port is used to discharge sediment and waste liquid.

[0021] The present invention will be further described in detail below with reference to embodiments: Example 1, such as Figure 1 - Figure 9As shown, this invention provides an intelligent spray deodorization device for livestock breeding sheds using bacterial liquid, comprising an intelligent control structure 1, a bacterial liquid storage structure 2, a spray execution structure 3, a gas monitoring structure 4, and a rotation and lifting adjustment structure 5. The device is characterized in that: the bacterial liquid storage structure 2 supplies bacterial liquid to the spray execution structure 3; the gas monitoring structure 4 detects the gas concentration and temperature inside the breeding shed; the rotation and lifting adjustment structure 5 adjusts the height of the spray execution structure 3 and drives its rotation; the intelligent control structure 1 includes a controller 11, a touch screen display 12, and a wireless communication structure 13, with the controller 11 electrically connected to both; the bacterial liquid storage structure 2 includes a bacterial liquid storage tank 21, which contains a stirring mechanism 25. The spraying execution structure 3 includes a main spraying pipe 32, one end of which is connected to the spraying pump 31 and a branch spraying pipe 33 is connected through a rotary sealing joint 37. The branch spraying pipe 33 is fixed with a rotary gear ring 36. The gas monitoring structure 4 includes an odor gas sensor 41 and a temperature and humidity sensor 42 fixed to the inner wall of the breeding house; The rotary lifting adjustment structure 5 includes a vertical rack 51, with a rotary adjustment motor 52 at its top. The vertical rack 51 meshes with a first transmission gear 54, which meshes with a rotating gear ring 36. The rotating gear ring 36 meshes with a second transmission gear 57. A receiving plate 56 rotates at the bottom of the second transmission gear 57. A height adjustment electric push rod 58 is provided at the bottom of the receiving plate 56. A guide frame 53 slides on the outer wall. A C-shaped frame plate 55 fixed to the receiving plate 56 is sleeved on the rotating gear ring 36.

[0022] The intelligent control structure 1 undertakes the core functions of signal reception, logical judgment, and command transmission. Its installation location is preferably on the wall near the entrance of the livestock shed, 1.5-1.8m above the ground. This facilitates operation of the touch screen display 12 by livestock personnel and avoids damage from livestock collisions. The controller 11 uses an S7-200 SMART PLC controller, which features small size, strong anti-interference capability, high-speed response, and convenient programming. It can adapt to the complex working environment of the livestock shed, characterized by high dust levels, high humidity, and electromagnetic interference. The number of its input / output interfaces can be flexibly expanded according to the actual number of sensors and actuators, up to a maximum of 32 input interfaces and 24 output interfaces, fully meeting the requirements of the linkage control of various structures in this device. The touch display screen 12 is a 7-inch industrial-grade touch screen with a resolution of 800×480. It is waterproof and dustproof with an IP65 protection rating. The surface is coated with a scratch-resistant and wear-resistant coating, which can effectively resist the pollution of dust and livestock excrement in the breeding house. It is connected to the controller 11 via an RS232 interface with a communication rate of up to 9600bps. Breeders can intuitively view parameters such as the concentration of odorous gases, temperature and humidity, remaining bacterial solution, and device operating status in the breeding house through the touch screen. At the same time, they can manually set parameters such as spraying time, spraying interval, odorous gas threshold, and stirring time. The operation is simple and convenient, and no professional programming knowledge is required. The wireless communication structure 13 adopts a dual-mode module of WiFi and 4G / 5G, model EC200S. It supports automatic switching of network modes. When there is a stable WiFi signal in the breeding house, WiFi mode is used first for communication to reduce communication costs. When the WiFi signal is unstable or interrupted, it automatically switches to 4G / 5G mode to ensure the continuity of remote communication. This module is connected to the controller 11 through the SPI interface, with a communication delay of ≤100ms. It supports remote login to mobile APP or computer client to view various operating parameters of the device in real time, remotely adjust spray parameters, start or stop spray operation, and even remotely troubleshoot simple faults, which greatly reduces the workload of on-site supervision by breeding personnel.

[0023] The bacterial solution storage structure 2 is used to store the deodorizing bacterial solution and ensure a stable supply of the solution. The bacterial solution storage tank 21 is made of transparent polypropylene (PP), a material that is corrosion-resistant, high-temperature resistant, non-toxic, odorless, lightweight, and high-strength. It can withstand long-term erosion by the deodorizing bacterial solution, and the transparent material allows farmers to visually observe the remaining amount and turbidity of the solution, enabling timely detection of spoilage or sedimentation. The volume of the bacterial solution storage tank 21 can be flexibly designed according to the area of ​​the breeding shed. For conventional large-scale breeding sheds (area 500-1000㎡), the preferred volume is 500-1000L, with a tank height of 1.2-1.5m and a diameter of 0.8-1.0m. The bottom of the tank adopts a conical structure to facilitate the collection of settled impurities and easy discharge through the drain outlet. The stirring mechanism 25 is installed at the top center of the bacterial liquid storage tank 21. The stirring motor 251 is a three-phase asynchronous motor of model Y2-90S-4 with a power of 1.1kW and a speed of 1440r / min. The motor housing adopts a waterproof and dustproof sealed structure with a protection level of IP65, which can adapt to the humid and dusty environment of the breeding house. The motor is fixed to the top of the bacterial liquid storage tank 21 by a flange. A rubber sealing gasket is set between the flange and the tank to prevent the bacterial liquid from evaporating or leaking. The stirring blades 252 are made of stainless steel with a thickness of 3-5mm. There are 3-4 blades arranged in a spiral shape. The diameter of the blades is 0.6-0.7 times the inner diameter of the bacterial liquid storage tank 21. The stirring blades 252 are connected to the output shaft of the stirring motor 251 by a flat key and fixed by a locking nut to ensure stable power transmission. When the stirring motor 251 starts, it drives the stirring blades 252 to rotate at high speed, which fully stirs the bacterial liquid, prevents the effective components in the bacterial liquid from settling and stratifying, and ensures the deodorizing activity of the bacterial liquid. The rotation direction of the stirring blades 252 can be set to clockwise. The stirring speed can be adjusted by the controller 11, with an adjustment range of 300-1000r / min, to adapt to the stirring needs of bacterial liquids of different concentrations.

[0024] The spraying actuator 3 is the core component for achieving bacterial liquid spraying and deodorization. It is responsible for atomizing the bacterial liquid and spraying it evenly to various areas of the breeding shed. The spray pump 31 is an ISG50-160 pipeline centrifugal pump with a flow rate of 10-15 m³ / h, a head of 20-30 m, and a power of 2.2 kW. This pump has the advantages of small size, high efficiency, low noise, and stable operation, and can provide sufficient pressure for bacterial liquid spraying. The pump inlet is connected to the bottom of the bacterial liquid storage tank 21 through a pipeline. A filter is installed at the inlet. The filter uses a stainless steel filter screen with a mesh size of 100-120 mesh to filter impurities in the bacterial liquid and prevent impurities from clogging the spray head 34 or the pipeline. The filter is designed to be detachable and washable for easy periodic cleaning of impurities. The main sprinkler pipe 32 is made of UPVC material with a diameter of 50-63mm and a wall thickness of 3-4mm. This material has the advantages of corrosion resistance, anti-clogging, light weight, and convenient installation. The length of the main sprinkler pipe 32 is flexibly designed according to the length of the breeding house. The corresponding length for a conventional breeding house is 10-20m. A fixed bracket is installed on the outer wall of the pipe every 1.5-2.0m. The fixed bracket is made of stainless steel and is fixed to the wall or roof of the breeding house with expansion bolts to ensure that the pipe is installed firmly and to prevent the pipe from loosening or falling off due to vibration during the sprinkler process. The rotary sealing joint 37 adopts an integrated structure of fluororubber seal and stainless steel shell. It is a K-type rotary joint. Its inner diameter is precisely matched with the outer diameter of the main spray pipe 32 and the branch spray pipe 33. The sealing surface is precision polished and the roughness is controlled within Ra0.8μm. It can effectively prevent the leakage of bacterial liquid during high-pressure spraying and rotation, while reducing the frictional resistance during rotation, extending the service life of the joint, and adapting to the working conditions of long-term continuous operation of the device. The rotary sealing joint 37 can rotate up to 360° without dead angles, ensuring the stable delivery of bacterial liquid during the rotation of the branch spray pipe 33.

[0025] The branch sprinkler pipes 33 are also made of UPVC material, with a pipe diameter of 32-40mm and a wall thickness of 2-3mm. The number of branch sprinkler pipes 33 can be flexibly set according to the width of the breeding house. The number corresponding to a conventional breeding house is 2-4 pipes. The length of each branch sprinkler pipe 33 is 5-8m. The branch sprinkler pipes 33 are connected to the outlet of the rotary sealing joint 37 by threads. Raw material tape is set at the threads to enhance the sealing and prevent the leakage of bacterial liquid. The rotating gear ring 36 is made of No. 45 steel and has been hardened to a hardness of HRC40-45, possessing good wear resistance and mechanical strength. The inner diameter of the rotating gear ring 36 is precisely matched with the outer diameter of the branch sprinkler pipe 33. It is fixed in the middle of the branch sprinkler pipe 33 by a clamp made of stainless steel and bolted to ensure that the rotating gear ring 36 rotates synchronously with the branch sprinkler pipe 33. The rotating gear ring 36 has 40-60 teeth with a tooth pitch of 5-8mm, which precisely meshes with the tooth profiles of transmission gear 1 54 and transmission gear 2 57 to ensure smooth power transmission without any jamming.

[0026] The gas monitoring structure 4 is used to collect environmental parameters in the livestock shed in real time, providing data support for intelligent sprinkler systems. The odor gas sensor 41 uses an electrochemical sensor of model MQ-137. This sensor has advantages such as high measurement accuracy, fast response speed, good stability, and strong anti-interference ability. It is mainly used to monitor the concentration of odorous gases such as ammonia and hydrogen sulfide in the livestock shed. The measurement range is 0-500ppm, the measurement accuracy is ±5ppm, the response time is ≤10s, and the recovery time is ≤30s. The sensor should be installed preferably in areas where odorous gases easily accumulate in the livestock shed, such as areas where livestock manure is piled up or near drinking water areas. The installation height should be 0.5-1.0m, more than 50cm above the ground, to avoid damage from livestock collisions and to ensure the accuracy of the measurement data. The temperature and humidity sensor 42 uses a DHT11 digital sensor, which features small size, low power consumption, high measurement accuracy, and easy installation. Its measurement range is 0-50℃ for temperature and 20%-90%RH for humidity, with a temperature measurement accuracy of ±0.5℃ and a humidity measurement accuracy of ±5%RH. The response time is ≤5s. The sensor is installed at a height of 1.0-1.2m, offset from the odor gas sensor 41, to ensure that the collected temperature and humidity data reflects the overall environmental conditions within the livestock shed. Both sensors are connected to the input interface of the controller 11 via wires. The wires are RVV2×0.75mm² shielded cables with grounded shielding to effectively resist electromagnetic interference within the livestock shed and ensure stable data transmission. The sensor housing has a waterproof and dustproof structure with an IP65 protection rating, enabling it to adapt to the humid and dusty environment of the livestock shed and extending the sensor's service life.

[0027] The rotary lifting adjustment structure 5 is used to adjust the rotation angle and height of the spray execution structure 3, expanding the spray coverage area and adapting to breeding sheds of different sizes. It is a key structure for improving the versatility of the device. The vertical rack 51 is made of 304 stainless steel, with a length of 1.0-1.5m, a diameter of 20-30mm, a tooth pitch of 5-8mm, and trapezoidal teeth, possessing good wear resistance and mechanical strength. The top of the vertical rack 51 is connected to the output shaft of the rotary adjustment motor 52 via a coupling. The coupling is an elastic coupling, which can buffer the impact force when the motor starts, protect the vertical rack 51 and the motor shaft, and compensate for installation deviations. The rotary adjustment motor 52 is a 57BYG250 stepper motor with a power of 0.75kW and a speed of 0-100r / min. The speed can be steplessly adjusted by the controller 11. The motor housing adopts a waterproof and dustproof sealed structure with a protection level of IP65. The motor is fixed to the top of the guide frame 53 by a bracket made of stainless steel to ensure a firm installation.

[0028] Both transmission gear 54 and transmission gear 57 are made of 45 steel and have been hardened to a hardness of HRC40-45. They have 15-20 teeth and the tooth pitch is precisely matched with the tooth pitch of the vertical rack 51 and the rotating gear ring 36. Transmission gear 54 is fixed in the middle of the guide frame 53 by bearings. The bearings are deep groove ball bearings, model 6204, which have the advantages of flexible rotation, low wear, and long service life. Transmission gear 54 meshes with the vertical rack 51 and the rotating gear ring 36 to realize the transmission of power, converting the rotational motion of the rotary regulating motor 52 into the rotational motion of the rotating gear ring 36, thereby driving the branch spray pipe 33 to rotate. The second transmission gear 57 is fixed to the top of the receiving plate 56 by a bearing. The bearing model is the same as that of the first transmission gear 54. The second transmission gear 57 meshes with the rotating gear ring 36, which plays a role in auxiliary support and stable rotation, preventing the rotating gear ring 36 from deviating or shaking during rotation, and ensuring that the branch spray pipe 33 rotates smoothly and sprays evenly.

[0029] The receiving plate 56 is made of Q235 steel plate with a thickness of 8-10mm, a length of 1.0-1.2m, and a width of 0.5-0.6m. It has good load-bearing capacity. The bottom of the receiving plate 56 is connected to the top of the height adjustment electric actuator 58 by bolt connection. The bolts are made of high-strength stainless steel to ensure a firm connection and to support the weight of the spray actuator 3 and the rotating gear ring 36. The height-adjustable electric actuator 58 is a DTZ300 model electric actuator with a stroke of 0.5-1.0m, a thrust of 3000N, and a speed of 50-100mm / s. The bottom end of the actuator is fixed to the ground by a bracket, which is made of concrete to ensure stable operation of the electric actuator. The height-adjustable electric actuator 58 is electrically connected to the controller 11. The controller 11 controls the extension and retraction of the actuator, thereby adjusting the height of the receiving plate 56, realizing the height adjustment of the spraying actuator 3. It is suitable for breeding houses of different heights (the height of conventional breeding houses is 2.5-4.0m). At the same time, the spraying height can be adjusted according to the height of livestock and poultry to avoid the bacterial liquid being sprayed directly onto the livestock and poultry, which would affect their growth.

[0030] The guide frame 53 is made of 304 stainless steel and has a frame structure with a height of 2.0-3.0m and a width of 0.6-0.8m. The inner wall of the guide frame 53 is equipped with T-shaped slide rails, the length of which is the same as the height of the guide frame 53. The outer wall of the receiving plate 56 is fixed with matching T-shaped sliders, which are slidably connected to the slide rails. The surface of the slide rails is coated with lubricating oil to reduce sliding friction and ensure that the receiving plate 56 can be raised and lowered smoothly without jamming. At the same time, the guide frame 53 can limit the offset of the receiving plate 56 and ensure the stability of the position of the spray actuator 3 during height adjustment, avoiding tilting or shaking. The C-shaped support plate 55 is made of 304 stainless steel with a thickness of 6-8mm. The opening size matches the outer diameter of the rotating gear ring 36. There are two sets of C-shaped support plates 55, symmetrically distributed on both sides of the rotating gear ring 36. Each set of C-shaped support plates 55 is fixed to the top of the receiving plate 56 with stainless steel bolts to ensure a firm fixation. A gap of 1-2mm is set between the inner wall of the C-shaped support plate 55 and the outer wall of the rotating gear ring 36. This gap does not affect the rotation of the rotating gear ring 36, but also provides auxiliary support and limit function for the rotating gear ring 36, preventing left and right deviation during the rotation of the rotating gear ring 36, and improving the overall structural stability and operational reliability of the device.

[0031] There are two sets of C-shaped support plates 55, which are symmetrically distributed on both sides of the rotating gear ring 36.

[0032] Multiple sets of spray heads 34 are evenly arranged at the bottom of the branch spray pipe 33, and a flow regulating valve 35 is provided on the outer wall of the main spray pipe 32.

[0033] The controller 11 is a PLC controller, and the odor gas sensor 41 is an electrochemical sensor with a measurement range of 0-500ppm.

[0034] The spray head 34 is a rotatable atomizing spray head with a rotation angle of 0-360° and an atomized particle diameter of 10-50μm.

[0035] The bacterial liquid storage tank 21 is made of transparent and corrosion-resistant material. It is equipped with a cleaning port and a drain port. The cleaning port is used to clean the bacterial liquid storage tank regularly, and the drain port is used to discharge sediment and waste liquid.

[0036] The stirring mechanism 25 is controlled by the controller 11 to start at a time. The stirring time and stirring interval can be set by the touch screen 12 or a mobile terminal.

[0037] The wireless communication structure 13 uses a WiFi or 4G / 5G module to support remote viewing of the device's operating status and adjustment of spray parameters.

[0038] In this embodiment, the linkage between the intelligent control structure 1 and the gas monitoring structure 4 enables on-demand spraying based on the concentration of odorous gases and temperature and humidity inside the shed, avoiding the subjectivity and lag of manual operation; the wireless communication structure 13 supports remote control and status viewing, eliminating the need for on-site personnel, greatly reducing the labor intensity of breeding personnel, and adapting to the needs of large-scale breeding.

[0039] The two sets of rotating gear rings 36 are arranged side by side, and can be linked by the transmission gear 2 57 to make the two sets of rotating gear rings 36 rotate synchronously, thereby driving the two sets of branch spray pipes 33 to rotate.

[0040] Example 2, as Figure 1 - Figure 9 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a liquid level sensor 22 is fixedly connected to the top of the bacterial liquid storage tank 21, and the stirring mechanism 25 includes a stirring motor 251 and stirring blades 252. The stirring motor 251 is fixed to the top of the bacterial liquid storage tank 21 and is electrically connected to the controller 11. A bacterial liquid supply pump 23 is fixed to the top of the bacterial liquid storage tank 21, and a supply pipe 24 is fixed to the inlet end of the bacterial liquid supply pump 23. Both the liquid level sensor 22 and the bacterial liquid supply pump 23 are electrically connected to the controller 11.

[0041] The rotating lifting and adjusting structure 5 can drive the spraying actuator 3 to rotate and adjust its height, completely eliminating the spraying blind spots of traditional fixed spraying devices. It can be adapted to livestock sheds of different heights and areas, improving the versatility and applicability of the device.

[0042] In this embodiment, the stirring mechanism 25 of the bacterial liquid storage structure 2 can prevent the bacterial liquid from settling and separating, thus ensuring the deodorizing activity of the bacterial liquid; the linkage between the liquid level sensor 22 and the bacterial liquid replenishment pump 23 realizes automatic replenishment of the bacterial liquid, avoiding the interruption of deodorization operation due to the depletion of bacterial liquid, and maintaining the continuity of the deodorization effect.

[0043] Example 3, as Figure 1 - Figure 9 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, the rotary sealing joint 37 is made of fluororubber seal and stainless steel shell material, which has the characteristics of corrosion resistance, wear resistance and good sealing performance, and is suitable for bacterial liquid transportation and rotary working conditions. The guide frame 53, vertical rack 51, transmission gear one 54, and transmission gear two 57 are all made of 304 stainless steel, which has good corrosion resistance and mechanical strength and is suitable for the humid environment of the breeding house. The bacterial culture storage tank 21 is made of transparent polypropylene (PP) material, which is corrosion resistant and makes it easy to observe the remaining bacterial culture. The main sprinkler pipe 32, branch sprinkler pipe 33, and sprinkler head 34 are all made of UPVC material, which is corrosion-resistant, anti-clogging, and suitable for bacterial liquid transportation. The receiving plate 56 and the guide frame 53 are connected by a slide rail and a slider. A T-shaped slide rail is set on the guide frame 53, and a matching T-shaped slider is fixed at the bottom of the receiving plate 56 to ensure that the lifting process of the receiving plate 56 is smooth and without jamming. The stirring blade 252 and the output shaft of the stirring motor 251 are connected by a flat key and fixed by a lock nut to ensure stable power transmission; The wireless communication structure 13 is connected to the controller 11 via an RS485 interface, which provides stable communication and strong anti-interference capabilities, making it suitable for the complex electromagnetic environment of the livestock house. The liquid level sensor 22 is connected to the bacterial liquid storage tank 21 by a flange, which facilitates installation, disassembly and maintenance. The housings of the controller 11, the rotary adjustment motor 52, and the height adjustment electric actuator 58 all adopt an IP65 protection level sealed structure to prevent moisture and dust from entering and ensure the safe operation of electrical components in humid environments. Both the inlet and outlet of the bacterial solution replenishment pump 23 are equipped with rubber sealing gaskets to prevent bacterial solution leakage.

[0044] The working principle of this intelligent spray deodorization device for livestock breeding is explained in detail below.

[0045] like Figure 1 - Figure 9As shown, the monitoring feedback is as follows: the odor gas sensor 41 and the temperature and humidity sensor 42 of the gas monitoring structure 4 are fixed to the inner wall of the breeding house, collect the concentration of odor gas and temperature and humidity data in the house in real time, and transmit the data to the controller 11 of the intelligent control structure 1.

[0046] Bacterial liquid storage and supply: The bacterial liquid storage tank 21 of the bacterial liquid storage structure 2 stores the deodorizing bacterial liquid. The stirring motor 251 of the stirring mechanism 25 drives the stirring blade 252 to rotate to prevent the bacterial liquid from settling and separating. The liquid level sensor 22 monitors the remaining amount of bacterial liquid in the bacterial liquid storage tank 21 in real time. When the remaining amount is lower than the preset value, the controller 11 starts the bacterial liquid replenishment pump 23 to replenish the bacterial liquid to the bacterial liquid storage tank 21 through the replenishment pipe 24.

[0047] Intelligent control instructions: The controller 11 receives feedback data from the gas monitoring structure 4 and, in conjunction with preset thresholds, sends control instructions to the spray execution structure 3 and the rotary lifting adjustment structure 5; at the same time, the touch screen 12 can manually set the spray parameters, and the wireless communication structure 13 supports mobile terminals to remotely view the device's operating status and adjust parameters.

[0048] Spraying Execution and Attitude Adjustment: The spray pump 31 of the spraying execution structure 3 is started, transporting the bacterial solution in the bacterial solution storage tank 21 to the main spray pipe 32. The flow regulating valve 35 regulates the bacterial solution flow rate. The bacterial solution enters the branch spray pipe 33 through the rotary sealing joint 37 and is finally atomized and sprayed out through the spray head 34. When the height of the spraying execution structure 3 needs to be adjusted, the rotary adjusting motor 52 is started, driving the vertical rack 51 to rotate. The vertical rack 51 drives the rotating gear ring 36 to rotate through the transmission gear 54. The rotating gear ring 36 drives the branch spray pipe 33 to rotate, realizing a wide-area spraying. Height Adjustment The electric actuator 58 pushes the receiving plate 56 upward, which in turn moves the I-shaped frame plate 55 and the rotating gear ring 36 upward, thereby driving the branch sprinkler pipes 33 to rise and fall. The guide frame 53 guides the movement of the receiving plate 56 to ensure stability during the lifting process. The transmission gear 57 engaged with the rotating gear ring 36 helps maintain rotational stability. At the same time, the two sets of parallel rotating gear rings 36 can be linked to rotate synchronously, thereby driving the two sets of branch sprinkler pipes 33 to rotate. The two sets of I-shaped frame plates 55 are symmetrically distributed on both sides of the rotating gear ring 36 to improve the structural support strength.
