Description

Technical Field

[0001] The invention belongs to the field of animal husbandry equipment and relates to disinfection equipment in animal husbandry, and in particular to an animal husbandry disinfection robot with adjustable coverage radius. Background Art

[0002] Animal husbandry is a pillar industry in my country's agricultural sector. Its development is crucial to ensuring adequate meat availability for the general public and the physical well-being of the Chinese people. Both the scale and technological advancements of my country's animal husbandry industry are experiencing rapid growth, with farming methods rapidly evolving from free-range farming to centralized, automated methods.

[0003] Amidst the industry's rapid growth, disease prevention and control remains a key bottleneck hindering the safe development of the pig farming industry. The existing disease prevention system primarily relies on traditional injection vaccinations combined with manual disinfectant spraying to control diseases. Disinfection operations primarily rely on manual spraying, which presents numerous blind spots, inaccurate disinfectant dosage control, insufficient disinfectant utilization, and high risk of human exposure. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the current disinfection operation in animal husbandry mainly relies on manual spraying, which has many blind spots in operation, insufficient utilization of disinfectant water, and high risk of personnel exposure. It provides a livestock disinfection robot with adjustable coverage radius, which can adjust the amount of disinfectant water according to the size of the site space, and use the air volume and wind speed control of the disinfectant water atomization air supply to enable the disinfector to achieve comprehensive coverage within the disinfection space.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a livestock disinfection robot with adjustable coverage radius, comprising a chassis frame, a disinfection water tank mounted above the chassis frame, a guide plate fixedly provided on the front side of the disinfection water tank of the chassis frame, a plurality of outward-spraying atomizing nozzles evenly provided on the top and both sides of the guide plate, a water spray pipe connecting the atomizing nozzles in series is arranged on the rear side of the guide plate, the water spray pipe is connected to the disinfection water tank through a metering pump, a fan mounting plate adjustable forward and backward is provided on the front side of the guide plate of the chassis frame, the middle part of the fan mounting plate is hollowed out and a speed-regulating fan is installed in front of the hollow part, the speed-regulating fan blows air backward and sends disinfection water outward along the gap between the guide plate and the fan mounting plate.

[0006] This robot, used in conjunction with a topographic map of the farm, locates its position within the farm and determines the area requiring disinfection. For example, using a piggery as an example, the robot's current location is determined by obtaining the height and width of the area perpendicular to the robot's movement direction from the topographic map. Future technological advancements could also allow the use of radar and cameras to provide real-time spatial information about the area within which the robot is moving. Based on the robot's movement speed and the height and width of the area at its current location, the required disinfectant volume can be calculated based on the volume of the space. The metering pump then adjusts the pumping speed according to the required volume, dispensing the solution through the atomizing nozzle. Because the atomized disinfectant sprayed from the atomizing nozzle has a limited coverage area, a deflector and fan are located at the front of the robot. Air is blown from the rear of the fan, directed through the deflector, and then distributed circumferentially through the gap between the deflector and the fan mounting plate, distributing the disinfectant solution to a wider area, ensuring uniform coverage of the disinfected area within the farm. When the site is small, that is, when the height and width are small, the speed of the speed-regulating fan is reduced, the fan mounting plate is moved forward, and the width of the gap between the guide plate and the fan mounting plate is increased. The airflow velocity is smaller and the air supply distance is smaller, which is adapted to the size of the site space. When the site is large, the air volume of the speed-regulating fan is increased, the fan mounting plate is moved backward, and the width of the gap between the guide plate and the fan mounting plate is reduced, so that the airflow can deliver the disinfectant to a farther location at a faster speed. This robot can adapt to the automatic disinfection of breeding sites with a height of less than 6 meters and a width of less than 12 meters. Combined with the spatial information of the breeding site, this robot can evenly spray disinfectant throughout the space to achieve comprehensive disinfection, and replace manual spraying to reduce the risk of human exposure.

[0007] Preferably, a slider is provided at the bottom of the fan mounting plate, and the chassis frame is provided with a screw rod for driving the slider to move forward and backward, and one end of the screw rod is connected to a screw motor.

[0008] Preferably, the deflector plate is provided with a plurality of rearwardly extending guide rods, each of which is fitted with a stopper at one end adjacent to the deflector plate. The stopper limits the maximum rearward movement of the fan mounting plate, ensuring that the height of the curved deflector and atomizing nozzle does not exceed the thickness of the stopper to prevent damage from being squeezed.

[0009] Preferably, a curved deflector is provided on the front side of the deflector, aligned with the center of the fan. The central portion of the curved deflector is convex forward and forms an arc-shaped transition to the circumference of the deflector. This deflector structure, which gradually transitions from the center to the circumference, evenly directs the airflow generated by the speed-controlled fan toward the circumference, reducing turbulence. The maximum height of the curved deflector does not exceed the thickness of the stop block.

[0010] Preferably, a lower guide block is provided at the lower portion of the front side of the guide plate. The thickness of the lower guide block is consistent with the thickness of the guide rod limit block. The upper side of the lower guide block is an arc-shaped side with a low middle and high ends. The lower guide block blocks the lower portion of both sides of the guide plate. When the site area is small, there is still enough gap between the fan mounting plate and the lower guide block for airflow to blow out. When the site area is large, the fan mounting plate moves backward and abuts against the lower guide block. The airflow between the fan mounting plate and the guide plate is blown upward, that is, obliquely upward, from above the lower guide block. Firstly, the airflow is concentrated to increase the flow rate and send the disinfectant water to a farther distance. Secondly, the obliquely upward airflow sends the disinfectant water in the form of a parabola, covering a farther area, while the nearby area can be covered by the lowest atomizing nozzle.

[0011] Preferably, the atomizing nozzles on the lowermost sides of the guide plate are arranged horizontally outward, and the atomizing nozzles on the lowermost sides of the guide plate are enclosed in the lower guide block, and the spray outlets of the atomizing nozzles are exposed outside the lower guide block.

[0012] Preferably, at least one guide rod is provided through the lower guide block to position the lower guide block.

[0013] Preferably, the disinfection water tank is provided with a water inlet at the top and a drain outlet at the bottom.

[0014] Preferably, a front radar is provided on the front side of the chassis frame, and a rear radar is provided on the rear side of the chassis frame; and a control box is provided on the rear of the chassis frame.

[0015] Preferably, the chassis frame is provided with four running wheels.

[0016] The present invention combines the spatial information of the breeding site and can evenly spray disinfectant into the entire space by adjusting the fan wind speed and the air supply gap, thereby achieving comprehensive disinfection and replacing manual spraying to reduce the risk of human exposure.

DETAILED DESCRIPTION

[0025] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0026] Example 1: A livestock disinfection robot with adjustable coverage radius, such as Figure 1-3 As shown. The device includes a chassis frame 1, with a disinfectant water tank 2 mounted on top of the chassis frame 1. The disinfectant water tank 2 is provided with a water inlet 3 at the top and a drain outlet 10 at the bottom. A front radar 8 is provided on the front side of the chassis frame 1, and a rear radar 9 is provided on the rear side of the chassis frame for positioning the robot within the venue. A control box 4 is provided at the rear of the chassis frame, and a guide plate 5 is fixedly provided on the front side of the disinfectant water tank 2 on the chassis frame 1. Fences 7 are provided on both sides of the disinfectant water tank 2, and the front and rear ends of the fence 7 are respectively fixed to the sides of the guide plate 5 and the control box.

[0027] Several outward-spraying atomizing nozzles 12 are evenly distributed on the top and sides of the deflector 5. These nozzles face outward, and the outer ends of each nozzle do not extend beyond the deflector. A water spray pipe 11, connecting each atomizing nozzle 12 in series, is arranged behind the deflector 5. The water spray pipe 11 is connected to the disinfectant water tank 2 via a metering pump. The chassis frame 1 is provided with a front-to-back adjustable fan mounting plate 6 in front of the deflector 5. The central portion of the fan mounting plate 6 is hollowed out, and a speed-adjustable fan 15 is mounted in front of the hollowed-out portion. The speed-adjustable fan 15 blows air backward and delivers disinfectant water outward along the gap between the deflector 5 and the fan mounting plate 6.

[0028] like Figure 1 、 2 As shown, a slider 16 is provided at the bottom of the fan mounting plate 6. The chassis frame is provided with a screw 17 that drives the slider forward and backward, and one end of the screw is connected to a screw motor 18. A plurality of guide rods 13 extending rearward are provided around the deflector 5. Each guide rod 13 is fitted with a stop block 14 at one end of the deflector.

[0029] An arc-shaped air guide cover 19 is provided on the front side of the air guide plate 5 in alignment with the center of the fan. The middle portion of the arc-shaped air guide cover bulges forward and transitions to the circumference of the air guide plate 5 in an arc shape.

[0030] Based on the robot's speed and the height and width of the current location, the required disinfectant volume is calculated based on the size of the space. The metering pump then adjusts its pumping speed according to the required volume, dispensing the water through the atomizing nozzle. Since the atomized disinfectant sprayed from the atomizing nozzle naturally has a limited coverage area, a deflector and fan are installed at the front of the robot. The adjustable-speed fan blows air from behind, directing it through the deflector and then distributing it around the gap between the deflector and fan mounting plate, distributing the disinfectant to distant locations and achieving uniform coverage of the disinfected area within the farm. For smaller farms (i.e., smaller height and width), the adjustable-speed fan is reduced in speed, and the fan mounting plate is moved forward, widening the gap between the deflector and fan mounting plate. This results in lower airflow and a shorter delivery distance, adapting to the size of the farm. For larger farms, the adjustable-speed fan's air volume is increased, and the fan mounting plate is moved backward, narrowing the gap between the deflector and fan mounting plate. This allows the airflow to reach a greater distance at a faster rate.

[0031] Example 2: A livestock disinfection robot with adjustable coverage radius, such as Figure 4-6 As shown. Based on Example 1, this embodiment is provided with a lower guide block 20 at the lower part of the front side of the guide plate 5. The thickness of the lower guide block is consistent with the thickness of the guide rod limit block. The upper side of the lower guide block 20 is an arc-shaped side with a low middle and high ends. The atomizing nozzles 12 on both sides of the guide plate 5 are arranged horizontally outward, and the atomizing nozzles on both sides of the guide plate are wrapped in the lower guide block 20, and the spray outlets of the atomizing nozzles are exposed outside the lower guide block. The two guide rods 13 on the lower part of the guide plate 5 are passed through the lower guide block 20 for positioning. The rest of the structure of this embodiment is the same as that of Example 1. The lower guide block 20 can be made of rubber material, foam material, etc.

[0032] When this embodiment is in use, the lower guide blocks shield the lower portions of both sides of the guide plate. When the site area is small, sufficient clearance remains between the fan mounting plate and the lower guide blocks for airflow. When the site area is larger, the fan mounting plate moves backward to abut against the lower guide block, and the airflow between the fan mounting plate and the guide plate is blown upward, or diagonally, from above the lower guide block. This concentrates the airflow and increases the flow rate, delivering the disinfectant to a greater distance. Furthermore, the diagonally upward airflow delivers the disinfectant in a parabolic trajectory, covering a more distant area, while allowing the atomizing nozzle at the bottom to cover nearby areas.
