Description

Technical Field

[0001] This utility model relates to the technical field of disinfection equipment for livestock farms, and in particular to an adjustable spray bar spraying mechanism for a road disinfection vehicle used in livestock farms. Background Technology

[0002] With the continuous development of large-scale livestock and poultry farming, the biosecurity risks of farms are also increasing. Regular disinfection of farm roads is a crucial part of disease prevention and control. The drug resistance of pathogens in farms is increasing year by year, requiring disinfectants to evenly cover the road surface and maintain effective contact time. Insufficient local dosage can easily accelerate the development of drug-resistant strains.

[0003] Currently, disinfection of roads within farms mainly relies on personnel carrying sprayers to apply pesticides. This method is labor-intensive, inefficient, and prone to problems such as inconsistency, missed applications, and over-application. Furthermore, close contact with disinfectant poses a threat to personnel's health.

[0004] Existing disinfection spraying systems suffer from prominent problems such as droplet drift and poor equipment adaptability. On the one hand, during outdoor operations, strong winds cause the sprayed disinfectant to drift away, resulting in uneven application and frequent instances of missed or excessive application. On the other hand, existing air curtain spraying systems are mostly large-scale plant protection machinery, bulky, difficult to maneuver, and ill-suited for use on farm roads. Therefore, there is an urgent need for a new type of air curtain boom spraying system that can solve these problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model provides an adjustable spray bar spraying mechanism for livestock farm road disinfection vehicles. It utilizes a fan and a guide airbag to form an air curtain barrier, effectively suppressing droplet drift. A modular nozzle assembly design is employed, mounted on an adjustment mechanism and a folding mechanism, allowing for arbitrary adjustment of the atomizing nozzle spacing, number, flow rate, angle, and height. An integrated bidirectional spiral stirring mechanism and a baffle plate tank ensure uniform mixing of the disinfectant and stable movement during operation.

[0006] This utility model is achieved by providing the following technical solution:

The atomizing nozzle (31) is mounted at the outlet end of the valve body (30). The knob (29) can adjust the spray flow rate. The valve body (30) can be arbitrarily mounted on the mounting rod I (34) and the mounting rod II (35) via the nozzle mounting component (32). On rod II (35), different atomizing nozzles (31) spacing, number and angle can be realized. A three-way pipe (33) is installed at the water inlet end of the valve body (30). The modular nozzle assembly (403) is connected by multiple water pipes (405) to realize the supply of disinfectant. The water pump (406) inlet is connected to the tank outlet (49), and a filter is provided at the water pump (406) inlet to prevent drug particles or impurities from damaging the water pump (406) and clogging the atomizing nozzles (31). The water pump (406) adopts a variable frequency motor to adjust the water pressure. The pressure of the disinfectant is accurately obtained by a pressure gauge. The water pump (406) outlet is connected to the modular nozzle assembly (403) through a water pipe.

6. The adjustable spray boom spraying mechanism for livestock farm road disinfection vehicles according to claim 1, characterized in that, The mixing tank unit (1) includes a mixing mechanism (101), a baffle plate (104), a tank (102) and a roll cage (103). The tank (102) is fixed on the roll cage (103), which is mounted on the frame (5). The mixing mechanism (101) and the baffle plate (104) are installed inside the tank (102).

7. The wind screen adjustable spray bar spray mechanism for livestock and poultry farm road sanitizing vehicle of claim 6 wherein, The stirring mechanism (101) includes a stirring shaft (39), a shaft seal (43), a left helical blade (38), a right helical blade (40), a stirring rod (37), a stirring motor (41), and a motor mounting base (42). The stirring shaft (39) is rotatably connected to the shaft seal (43), and the shaft seal (43) is installed on the flange cover (44) of the medicine tank (102). The stirring shaft (39) has a left helical blade (38) and a right helical blade (40) at both ends, and a stirring rod (37) in the middle. The stirring motor (41) is installed on the flange cover (44) through the motor mounting base (42) to drive the stirring shaft (39) to rotate, which can fully mix the disinfectant in the medicine tank (102) and prevent the disinfectant from stratifying and settling.

8. The wind screen adjustable spray bar spray mechanism for livestock and poultry farm road sanitizing vehicle of claim 7, wherein, The medicine tank (102) includes a flange cover (44), a tank body (45), a rear cover (47), a tank inlet (46), and a tank outlet (49). The rear cover (47) is provided with an observation window (48) with scale lines, which can quickly obtain the content of disinfectant in the medicine tank (102). Two anti-surge plates (104) are installed inside the tank body (45), which divide the tank body (45) into three spaces. The anti-surge plates (104) have multiple small holes above and a fan-shaped opening area below, which can effectively reduce the fluctuation and impact of disinfectant in the tank body (45).

9. The wind screen adjustable spray boom spray mechanism for livestock and poultry farm road sanitizing vehicle of claim 1 wherein, The air curtain unit (3) includes a guide airbag (304), a fan (301), a fan mounting plate (303), and a fan mounting bracket (302). The guide airbag (304) is installed below the fan (301), and the fan (301) is installed on the movable plate (11) of the height adjustment mechanism (401) through the fan mounting plate (303) and the fan mounting bracket (302).

10. The wind screen adjustable spray boom spray mechanism for livestock and poultry farm road sanitizing vehicle of claim 9, wherein, The air guide bag (304) is provided with air holes (51) and a tow rope (50). The air holes (51) are symmetrically distributed on both sides of the spray direction of the atomizing nozzle. The air pressure inside the air guide bag (304) is increased by the operation of the fan (301), and the airflow is sprayed outward through the air holes (51). This can form a closed-loop air curtain around the atomized jet sprayed from the atomizing nozzle (31), thereby achieving wind protection and preventing the fog droplets from drifting. The tow rope (50) is installed on the rope buckle (28). The stability and direction adjustment of the air curtain are achieved by the tow rope (50). The height of the fan (301) to the atomizing nozzle (31) is adjusted by the fan mounting plate (303) and the fan mounting bracket (302), thereby achieving the adaptation of the air curtain coverage area to the atomized jet.
