The switch assembly allows for flexible sealing of the powder outlet, making switching between the two modes simple and reliable, preventing disinfectant solution from being discharged from the powder outlet. Based on the mouth-shaped grip, this application adds a first, second, and third strap to reduce the individual stress on the wrist and prevent wrist strain or injury from prolonged operation.

Description

Technical Field

[0001] This invention relates to the field of disinfection technology for livestock and poultry farms, and more particularly to a disinfection and treatment device for livestock and poultry farms. Background Technology

[0002] Animal husbandry is a core branch of agriculture. Essentially, it involves the artificial breeding and reproduction of terrestrial economic animals (pigs, cattle, sheep, horses, poultry, rabbits, fur-bearing animals, etc., and broadly includes medicinal animals and some intensively farmed aquatic economic animals) through long-term domestication and selective breeding, in order to obtain products such as meat, eggs, milk, fur, and medicinal materials. Animal husbandry pest control is a targeted pathogen inactivation operation performed on the entire breeding chain, not ordinary cleaning: it focuses on killing / removing pathogenic microorganisms (bacteria, viruses, fungi, parasite eggs) and harmful organisms (rats, flies, ticks, etc.) in the environment, covering all breeding-related scenarios. Common disinfection measures include spray disinfection, powder disinfection, and physical disinfection. Spray disinfection often uses backpack electric sprayers to spray disinfectant; powder disinfection involves spraying dry powder disinfectant or lime to inactivate pathogens and improve humidity in the factory; and physical disinfection uses high temperature or fire to kill pathogens.

[0003] Existing powder disinfection methods only use plastic buckets filled with powder, requiring manual bending over to sprinkle the powder. This is not only physically demanding but also results in uneven distribution. Therefore, a new disinfection and treatment equipment for livestock and poultry farms is needed to solve these problems. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a disinfection and treatment device for livestock and poultry farms.

[0008] According to the technical solution provided in the embodiments of this application, the airflow assembly includes an airbag disposed between the mouth-shaped grip and the mouth-shaped connecting rod. The bottom end of the airbag is provided with an air inlet duckbill valve, and the top end is provided with an air outlet duckbill valve. The air outlet duckbill valve is fitted with a connecting hose, and the other end of the connecting hose is fitted with a threaded thin tube. The mouth-shaped grip located above the material tube has a threaded hole that communicates with the inside of the material tube, and the top of the threaded hole is threadedly connected to the threaded tube.

[0009] According to the technical solution provided in the embodiments of this application, the air outlet duckbill valve and the air inlet duckbill valve are integrally manufactured and each includes a valve body, an intermediate ring and a threaded connector. The bottom end of the airbag is provided with an extension sleeve. The valve body of the air inlet duckbill valve is located inside the extension sleeve. The intermediate ring is bonded to the extension sleeve. The top end of the airbag is provided with an internal threaded sleeve. The threaded connector of the air outlet duckbill valve is threadedly connected to the internal threaded sleeve. The connecting hose is covered outside the valve body and bonded to the intermediate ring.

[0010] According to the technical solution provided in the embodiments of this application, the bottom of the mouth-shaped grip is provided with an inclined hole that is inclined towards the powder outlet and passes through the threaded hole and the outer wall of the material tube. A sealing post is inserted into the inclined hole, and a marking line is provided in the middle of the sealing post. When the marking line is fully exposed, the material tube is connected to the inclined hole. When the sealing post is fully inserted into the inclined hole, the material tube is sealed to the inclined hole.

[0011] According to the technical solution provided in the embodiments of this application, the top and bottom of the mouth-shaped connecting rod are provided with guide posts, the top and bottom of the mouth-shaped grip are provided with guide holes for the guide posts to slide through, and a return spring is fitted on the outside of the guide posts.

[0012] According to the technical solution provided in the embodiments of this application, the top of the first material box is embedded with an upper threaded cylinder and the bottom is provided with a lower threaded cylinder. The second material box is cylindrical and the top opening extends away from the center to form a support edge. The upper threaded cylinder is externally threaded with an upper cover, and the lower threaded cylinder is externally threaded with a lower cover.

[0013] According to the technical solution provided in the embodiments of this application, the material tube is further provided with a first strap and a second strap. The first strap can be tied at the wrist, and the second strap can be tied at the forearm on the front side of the elbow. A third strap is connected to one side of the second strap through at least two connecting straps. The third strap can be tied at the upper arm on the back side of the elbow.

[0014] According to the technical solution provided in the embodiments of this application, both the first strap and the second strap are fitted onto the outside of the material tube by means of a fixing accessory. The fixing accessory includes a fixing sleeve fitted onto the outside of the material tube and an arm support provided on the outer wall of the fixing sleeve and adapted to the arm.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features a first tank for storing disinfectant solution and a second tank for storing disinfectant powder. A connecting pipe allows for switchable connection to either the second tank or a liquid pump, enabling dual functions of dry powder application and liquid spraying. When the connecting pipe is connected to the second tank, the disinfectant powder automatically falls along the powder outlet of the pipe under gravity, eliminating the need for manual application and significantly reducing labor intensity. When the connecting pipe is switched to the liquid pump, the disinfectant solution is pumped to a nozzle at the end of the pipe, meeting the needs of different disinfection scenarios. Furthermore, the switch assembly allows for flexible sealing of the powder outlet, making switching between the two modes simple and reliable, and preventing disinfectant solution from being discharged from the powder outlet.

[0016] 2. Building upon its dual-purpose function, the nozzle can be quickly switched by gripping the mouth-shaped handle and pulling the mouth-shaped connecting rod via the transmission unit. During the switching process, the clamping block of the transmission unit first approaches the trapezoidal block, then abuts against it. The clamping block moves along the clamping edge, causing the trapezoidal block and the mounting sleeve to rotate. Subsequently, the pushing block inserts between the trapezoidal blocks for limiting and fixing, thus ensuring the stable positioning of the mounting sleeve after switching. This design allows operators to select the appropriate spray pattern from three nozzle types—fan-shaped nozzle, cone-shaped nozzle, and direct-shot nozzle—according to actual needs. The switching process is smooth and the positioning is precise, effectively improving the adaptability and efficiency of disinfection operations.

[0017] 3. Building upon its dual-function design, when the hand grips the mouthpiece handle and pulls the mouthpiece linkage, the airbag simultaneously injects auxiliary airflow into the feed tube, driving the disinfectant powder to be discharged more smoothly and preventing powder from clogging due to accumulation. Furthermore, the airbag is equipped with inlet and outlet duckbill valves to ensure that the airflow is always unidirectional, preventing backflow and powder backflow. Additionally, the oblique holes on the inner wall of the feed tube align the auxiliary airflow direction with the disinfectant powder flow direction, improving the airflow pushing efficiency.

[0018] 4. This application adds a first strap, a second strap, and a third strap to the existing mouth-shaped grip. The first strap is strapped to the wrist, the second strap is strapped to the forearm in front of the elbow, and the third strap is connected to the second strap via at least two connecting straps and strapped to the upper arm behind the elbow. This three-strap synergistic structure allows the entire arm to participate in the auxiliary grip, distributing part of the weight of the tube to the forearm, significantly reducing the individual stress on the wrist, avoiding wrist strain or injury caused by prolonged operation, and improving the stability and control precision of the tube operation.

[0019] 5. In addition, when the hand holds the mouth-shaped handle and pulls the mouth-shaped linkage, the cooperation between the guide post and the guide hole provides precise guidance for the movement of the mouth-shaped linkage and the long sleeve, effectively suppressing the sway and jamming during the movement, ensuring the coordination and consistency of the movement of each part of the transmission unit, further improving the reliability of switching operation and auxiliary triggering functions, and a return spring is installed on the outer sleeve of the guide post, which works with the compression spring to realize the reset of the long sleeve, making it convenient for the next use.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please refer to Figures 1-10 An embodiment of the present invention provides a disinfection and treatment device for livestock and poultry farms, comprising: The storage assembly 1 includes a first tank 11 for storing disinfectant liquid and a second tank 13 installed inside the first tank 11 for storing disinfectant powder. The first tank 11 is equipped with a liquid pump 112 for pumping disinfectant liquid, and the second tank 13 has a discharge port 16 at the bottom. The top of the first tank 11 is equipped with a battery 111 located on one side of the top cover 17. The output end of the battery 111 is electrically connected to the input end of the liquid pump 112 to provide power to the liquid pump 112.

[0026] The spray bar assembly 2 includes a feed tube 21, which has a powder outlet and a liquid outlet 31 on its side surface at the end. A connecting tube 22 is connected to the first end of the feed tube 21. The other end of the connecting tube 22 is detachable and can be installed between the outlet of the liquid pump 112 and the discharge port 16. A mouth-shaped handle 210 is provided in the middle of the feed tube 21. The nozzle assembly 3 includes a detachable mounting sleeve 32 sleeved on the end of the material tube 21. The mounting sleeve 32 has several stations evenly distributed, one station is a closed station, and the other stations are equipped with nozzles 34, one of which is connected to the liquid outlet 31. The switching component 4 includes a long sleeve 41 sleeved outside the material tube 21. The long sleeve 41 has a mouth-shaped connecting rod 48 at the first end and a transmission part at the end. The transmission part is used to drive the mounting sleeve 32 to rotate and switch the working position corresponding to the liquid outlet 31 during the process of the mouth-shaped connecting rod 48 moving toward the mouth-shaped handle 210 and resetting. The airflow assembly 5 is located on the mouth grip 210 and is used to inject auxiliary airflow toward the powder outlet into the middle of the feed tube 21 during the process of the mouth link 48 moving toward the mouth grip 210 and resetting. The switching assembly includes a threaded plug 61 for opening and closing the powder outlet, and a sealing post 62 for opening and closing the auxiliary exhaust flow.

[0027] The operator holds the mouth-shaped grip 210 and can achieve two working modes through the selective installation of the connecting tube 22.

[0028] Powder disinfection mode: The connecting pipe 22 is connected to the outlet 16 of the second material box 13. The disinfection powder is sprinkled from the powder outlet through the material pipe 21 under the action of gravity.

[0029] Disinfection mode: Connecting pipe 22 connects to the outlet of liquid pump 112. After starting liquid pump 112, the disinfectant is drawn and sprayed out from nozzle 34 through material pipe 21. In addition, the hand holds the mouth-shaped handle 210 and pulls the mouth-shaped connecting rod 48. The work station can be quickly switched through the transmission part. Optionally, four work stations are set. In addition to the closed work station, the other three work stations are respectively equipped with fan-shaped nozzles, cone nozzles and direct nozzles. According to different disinfection scenarios, the appropriate spray pattern can be selected. The switching process is smooth and the positioning is accurate, which effectively improves the adaptability and efficiency of disinfection operations.

[0030] By switching between two working modes, the system achieves dual functionality of dry powder application and liquid spraying, solving the problems of high fatigue intensity and uneven application associated with existing powder disinfection methods. Furthermore, in liquid disinfection mode, a threaded plug 61 needs to be installed at the powder outlet, ensuring that the disinfectant can only be sprayed from the nozzle 34. In powder disinfection mode, the sealing position is moved to correspond with the liquid outlet 31, sealing it to prevent powder from entering the nozzle 34 and causing damage.

[0031] Furthermore, an airflow assembly 5 is provided to inject auxiliary airflow toward the powder outlet into the middle of the material pipe 21, driving the sterilizing powder to be discharged more smoothly and avoiding clogging due to powder accumulation. In addition, the airflow assembly 5 and the switching assembly 4 are triggered by the same pull method, and the two are used in different modes without interfering with each other, improving the stability of their operation.

[0032] In some embodiments, the transmission part includes a trapezoidal block 44 disposed on the outer surface of the mounting sleeve 32, a pressing block 42 disposed on one side of the inner wall of the long sleeve 41 corresponding to the trapezoidal block 44, and a pushing block 43 disposed on the other side. The end face of the pushing block 43 near the trapezoidal block 44 has a pushing inclined surface 431, and the pushing inclined surface 431 is parallel to the pushing waist surface 442 of the trapezoidal block 44. The mounting sleeve 32 has a top ring 45 that slides around the material tube 21 on one side, and a fixed guide ring 47 that is fixedly mounted around the material tube 21. A pressure spring 46 is provided between the fixed guide ring 47 and the top ring 45. The long sleeve 41, the push block 43, and the top ring 45 are connected by screws. The threaded plug 61 has a limiting circular plate that abuts against the mounting sleeve 32. The outer surface of the fixed guide ring 47 fits against the inner surface of the long sleeve 41 to ensure the stable movement of the long sleeve 41.

[0033] In the first phase of the switch, refer to Figure 6In the first two schematic diagrams, the long sleeve 41 is pulled to the right, which causes the clamping block 42 and the pushing block 43 to move to the right. When the clamping block 42 abuts against the trapezoidal block 44, there is a first gap between the pushing block 43 and the mounting sleeve 32. At this time, the pushing block 43 will not interfere with the movement of the trapezoidal block 44. In the second phase of the switch, refer to Figure 6 In the two middle schematic diagrams, the long sleeve 41 continues to be pulled, the clamping block 42 continues to move along the pressure waist surface 441, pushing the trapezoidal block 44 to move downward, causing the annular mounting sleeve 32 to rotate; In the third stage of the switch, refer to Figure 6 In the last two diagrams, the long sleeve 41 is released, and under the action of the top pressure spring 46, the top ring 45 moves to the left. At this time, the pushing inclined surface 431 of the pushing block 43 contacts the pushing waist surface 442 of the trapezoidal block 44. Because they are set in parallel, they will continue to push the trapezoidal block 44 downward. Finally, the top pressure spring 46 pushes the top ring 45 and the pushing block 43, so that the pushing block 43 is inserted between the two trapezoidal blocks 44, thus achieving the purpose of switching work positions.

[0034] In this mode, the limiting circular plate of the threaded plug 61 restricts the installation sleeve 32, preventing the installation sleeve 32 from being pushed to the left by the push block 43. In the powder disinfection mode, there is no threaded plug 61 and the powder outlet is facing downwards. The installation sleeve 32 hangs down, so that the trapezoidal block 44 is always in contact with the pressing block 42, which in turn pulls the mouth-shaped connecting rod 48. This will only squeeze the airbag 51 and will not drive the station switching, so that the closed station always seals the liquid outlet 31.

[0035] In some embodiments, an installation bend 33 is installed at the workstation, and the nozzle 34 is connected to the installation sleeve 32 through the installation bend 33. The orientation of the nozzle 34 is parallel to the extension direction of the material tube 21.

[0036] The nozzle 34 is parallel to the axis of the feed tube 21, thus ensuring that the sprayed disinfectant is directed towards the target area along the feed tube 21. This ensures that the nozzle 34 sprays in a consistent direction, allowing the operator to aim at the target without adjusting the angle of their arm, simplifying the operation and improving spraying accuracy.

[0037] In some embodiments, the airflow assembly 5 includes an airbag 51 disposed between the mouth grip 210 and the mouth link 48. The airbag 51 has an air intake duckbill valve 53 at its bottom end and an air outlet duckbill valve 55 at its top end. The air outlet duckbill valve 55 is fitted with a connecting hose 56, and a threaded tube 57 is installed at the other end of the connecting hose 56. The mouth-shaped grip 210 located above the feed tube 21 is provided with a threaded hole 58 that communicates with the inside of the feed tube 21, and the top of the threaded hole 58 is threadedly connected to the threaded tube 57.

[0038] Among them, the duckbill valve is a one-way valve. In the powder disinfection mode, when the operator pulls the mouth-shaped connecting rod 48, the mouth-shaped connecting rod 48 approaches the mouth-shaped handle 210, compressing the air bag 51. The gas inside the air bag 51 passes through the outlet duckbill valve 55 in sequence through the connecting hose 56, the threaded thin tube 57 and the threaded hole 58, and finally is injected into the material tube 21. After being released, the top pressure spring 46 pulls the top ring 45, the push block 43 and the long sleeve 41 to reset, which in turn drives the mouth-shaped connecting rod 48 to reset. External gas enters into the air bag 51 from the inlet duckbill valve 53, realizing the air bag 51 inhaling and expanding. This process is repeated. Each time the air bag 51 is compressed, it will inject the auxiliary exhaust flow into the material tube 21, which serves to repeatedly push the powder and improve the powder discharge efficiency.

[0039] In some embodiments, the exhaust duckbill valve 55 and the intake duckbill valve 53 are integrally manufactured and each includes a valve body, an intermediate ring and a threaded connector. The bottom end of the airbag 51 is provided with an extension sleeve 52. The valve body of the intake duckbill valve 53 is located inside the extension sleeve 52. The intermediate ring is bonded to the extension sleeve 52. The top end of the airbag 51 is provided with an internal threaded sleeve 54. The threaded connector of the exhaust duckbill valve 55 is threadedly connected to the internal threaded sleeve 54. The connecting hose 56 is covered outside the valve body and bonded to the intermediate ring.

[0040] The two duckbill valves adopt the same integrated structure and are installed at both ends of the airbag 51 respectively. The bottom air intake duckbill valve 53 is not removable, while the top air outlet duckbill valve 55 can be removed by thread. The threaded tube 57 can also be removed from the threaded hole 58, so that the airbag 51 and the connecting hose 56 are divided into two parts, which facilitates the direct replacement of parts during maintenance and improves service life. More preferably, one end face of the airbag 51 is provided with at least two rubber pins 510, and the mouth-shaped handle 210 is provided with mounting holes for the rubber pins 510 to pass through at the corresponding positions, which facilitates the maintenance and replacement of the airbag 51.

[0041] In some embodiments, the bottom of the mouth-shaped grip 210 is provided with an inclined hole 59 that is inclined toward the powder outlet and passes through the threaded hole 58 and the outer wall of the tube 21. A sealing post 62 is inserted into the inclined hole 59. A marking line 63 is provided in the middle of the sealing post 62. When the marking line 63 is fully exposed, the tube 21 and the inclined hole 59 are connected. When the sealing post 62 is fully inserted into the inclined hole 59, the tube 21 and the inclined hole 59 are sealed.

[0042] refer to Figure 10As shown, the threaded hole 58 is opened from top to bottom on the top surface of the beak-shaped grip 210. The beak-shaped grip 210 is then welded to the feed tube 21. A hole is drilled obliquely downwards from the side of the beak-shaped grip 210, penetrating the outer wall of the feed tube 21, forming the current oblique hole 59. This facilitates the airflow from the threaded tube 57 into the threaded hole 58, then from the threaded hole 58 into the oblique hole 59, and finally, it is discharged obliquely into the feed tube 21, ensuring effective airflow. The marking line 63 serves as a marker to help the user accurately maintain the position of the sealing post 62 and avoid excessive pulling. Optionally, a retaining ring 64 is installed at the outer end of the sealing post 62 to facilitate pulling the sealing post 62, improving the ease of operation.

[0043] In some embodiments, the mouth-shaped connecting rod 48 is provided with guide posts 410 at both the top and bottom, and the mouth-shaped grip 210 is provided with guide holes 49 at both the top and bottom for the guide posts 410 to slide through. A return spring 411 is fitted around the guide posts 410.

[0044] When the mouth-shaped link 48 approaches the mouth-shaped grip 210, the return spring 411 contracts. Then, after releasing the mouth-shaped link 48, the return spring 411 returns to its original position, driving the mouth-shaped link 48. In conjunction with the top pressure spring 46, this avoids the situation where it is difficult to return to its original position if only the top pressure spring 46 is used. In addition, the stability of the movement of the mouth-shaped link 48 is improved by the cooperation of the guide post 410 and the guide hole 49.

[0045] In some embodiments, the top of the first material box 11 is provided with an upper threaded cylinder 12 and the bottom is provided with a lower threaded cylinder 18. The second material box 13 is cylindrical and the top opening extends away from the center to form a support edge 14. The upper threaded cylinder 12 is externally threaded to an upper cover 17 and the lower threaded cylinder 18 is externally threaded to a lower cover 19.

[0046] In liquid disinfection mode, the lower threaded cylinder 18 is sealed by the lower cover 19, and the second material box 13 is removed, allowing disinfectant to be injected into the first material box 11. Then, the liquid pump 112 is started to spray the disinfectant. In powder disinfection mode, the upper threaded cylinder 12 is supported by the support edge 14, and the lower cover 19 is removed. The connecting pipe 22 is connected to the outlet 16 of the second material box 13. Optionally, the bottom of the second material box 13 is provided with a guide block 15, the top surface of which is inverted conical and the middle is through to form the outlet 16, allowing the disinfectant powder to be discharged smoothly. In the idle state, the second material box 13 is placed inside the first material box 11 and sealed with the upper cover 17 and the lower cover 19. Optionally, the outside of the first material box 11 is provided with a shoulder strap 113, and the bottom end is provided with a support leg 110, the bottom surface of which is lower than the bottom surface of the lower cover 19. To prevent the lower cover 19 from contacting the ground and improve the stability of the first material box 11, the use of the shoulder strap 113 makes it convenient for the user to carry the first material box 11.

[0047] In some embodiments, the feed tube 21 is further provided with a first strap 25 and a second strap 27. The first strap 25 can be tied to the wrist, and the second strap 27 can be tied to the forearm on the front side of the elbow. A third strap 29 is connected to one side of the second strap 27 by at least two connecting straps 28. The third strap 29 can be tied to the upper arm on the back side of the elbow.

[0048] The operator attaches the first strap 25 to the wrist, the second strap 27 to the forearm (in front of the elbow), and the third strap 29 to the upper arm (behind the elbow). The three straps work together to form a unified support system for the arm. The weight of the material tube 21 is distributed to the forearm and upper arm through the straps and can be adjusted by rotating the elbow without the need for wrist exertion. This avoids wrist strain caused by prolonged operation and improves the stability and control precision of the material tube 21. In addition, the third strap 29 is connected to one side of the second strap 27 by at least two connecting straps 28 to prevent the straps from sliding along the arm, improving the stability after binding and making it less likely to loosen.
