Description

Technical Field

[0001] This invention relates to the field of crop powdery mildew control technology, and in particular to an ozone atomizing sprayer for controlling powdery mildew in greenhouse crops. Background Technology

[0002] Dissolved ozone (ozonated water) is sprayed through a misting system to contact the stems, leaves, and fruits of crops. The strong oxidizing properties of ozone destroy the cell membranes and nucleic acids of pathogens, thus achieving sterilization and providing supplementary control of powdery mildew. Many factors influence the effectiveness of this control, and whether the spray adequately covers the contact surface is one of the most direct factors. Existing sprayers, whether portable or stationary, typically use a jet-like beam atomization method, covering only a single contact surface and failing to cover the back of the contact surface. When encountering near-rotating stems and fruits, frequent oscillations at multiple angles are required for complete coverage, which is not only time-consuming and labor-intensive but also prone to omissions, thus reducing sterilization effectiveness and work efficiency. While some sprayers have a ring-shaped or arc-shaped spray structure, which can increase the coverage area of ​​rotating structures, it cannot simultaneously adapt to large-area flat operations. Furthermore, this structure cannot be adjusted in size, making it impossible to tailor the spray to rotating bodies of different diameters. This results in problems where the spray is too close, resulting in insufficient coverage, or too far, resulting in incomplete coverage, thus reducing practicality and work efficiency. These shortcomings of existing technologies are highlighted. Summary of the Invention

[0003] The purpose of this invention is to provide an ozone atomizing sprayer for the prevention and control of powdery mildew in greenhouse crops, so as to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An ozone atomizing sprayer for controlling powdery mildew in greenhouse crops includes a moving mechanism, a water pump, a controller, a support frame, swing arms, a clamping mechanism, a spray pipe, atomizing elements, and an elastic pulling mechanism. The moving mechanism is equipped with a water pump, a controller, and a support frame. Swing arms are mounted on both the left and right sides of the support frame. Clamping mechanisms are installed at the ends of the two swing arms furthest from the support frame. The two swing arms can controllably drive the clamping mechanisms to swing left and right. There is a height difference between the two clamping mechanisms, which is greater than the maximum outer diameter of the target crop stem. The two clamping mechanisms jointly clamp a flexible spray pipe. The spray pipe contains multiple atomizing elements connected to the outside. An elastic pulling mechanism is jointly installed on the support frame and the swing arms. The elastic pulling mechanism is controllably detached from the spray pipe to elastically pull the spray pipe closer to the support frame and the swing arms. The controller is electrically connected to the water pump and is powered by an external power source. The drain pipe of the water pump is connected to the spray pipe via a spare flexible hose.

[0006] Based on the above technical solution, the swing arm includes a support member, a secondary swing arm, and a servo motor. Support members are installed on both the left and right sides of the support frame. Secondary swing arms are hinged to the left and right sides of each of the two support members. The two secondary swing arms are respectively installed with a clamping mechanism. A servo motor is installed on each of the two support members. The rotation shafts of the two servo motors are fixed to the secondary swing arms. The rotation shafts of the two servo motors are coaxial with the virtual hinge shafts of the secondary swing arms. The two servo motors are electrically connected to a controller. When the two servo motors rotate, they can drive the two secondary swing arms to swing left and right.

[0007] Based on the above technical solution, the support component includes a support base, a main swing arm, and a rotary drive mechanism. The left and right sides of the support frame are each rotatably connected to a horizontal support base. The two support bases are each equipped with a main swing arm, and the two main swing arms are respectively hinged to the two auxiliary swing arms. The virtual rotation axis of the support base is arranged horizontally to the left and right. The support frame is equipped with a rotary drive mechanism, which is used to controllably drive the support base to rotate, thereby driving the main swing arm to swing up and down. When the main swing arm swings up and down, it drives the auxiliary swing arm to swing up and down synchronously, thereby changing the height difference between the positions of the two clamping mechanisms.

[0008] Based on the above technical solution, the rotary drive mechanism includes a first servo motor, a first bevel gear, and a second bevel gear. The first servo motor is fixed at the front of the support frame. The first bevel gear is coaxially fixed to the rotating shaft of the first servo motor. The two support seats are respectively fixed with second bevel gears. The second bevel gears are coaxially arranged with respect to the virtual rotation axis of the support seat. The first bevel gear meshes with the two second bevel gears. The first servo motor has a braking function and is electrically connected to the controller. When the first servo motor rotates forward and backward, it can drive the support seat to rotate up and down in opposite directions through the meshing of the first bevel gear and the second bevel gear.

[0009] Based on the above technical solution, the support frame is rotatably connected to a bidirectional lead screw. The left and right parts of the bidirectional lead screw are symmetrically arranged and rotatably connected to the support bases respectively. The bidirectional lead screw is coaxially arranged with the virtual rotating shafts of the two support bases. The left and right parts of the bidirectional lead screw are threadedly connected to the two main swing arms respectively. The two main swing arms are slidably connected to the support bases respectively. The sliding direction of the two main swing arms relative to the support bases is parallel to the axial direction of the bidirectional lead screw. A No. 3 bevel gear is coaxially fixed in the middle of the bidirectional lead screw. A No. 2 servo motor with braking function is fixed at the bottom of the support frame. A No. 4 bevel gear is coaxially fixed on the rotating shaft of the No. 2 servo motor. The No. 4 bevel gear meshes with the No. 3 bevel gear. The No. 2 servo motor is electrically connected to the controller. When the No. 2 servo motor rotates forward and backward, it can drive the bidirectional lead screw to rotate forward and backward through the No. 4 bevel gear and the No. 3 bevel gear, thereby driving the two main swing arms to slide closer and further apart along the support bases.

[0010] Based on the above technical solution, the elastic traction mechanism includes an adjusting groove, a secondary traction rod, a hinge seat, a main traction rod, a tension spring, a hook, a buckle, a roller, and a handle. The secondary swing arm extends vertically through the adjusting groove, and the secondary traction rod is slidably connected between the two adjusting grooves. The secondary traction rod can slide laterally and swing left and right along the adjusting groove. A hinge seat is fixed to the rear of the support frame, and the main traction rod is hinged to the left and right sides of the hinge seat. The ends of the main traction rod and the secondary traction rod in their extending directions are respectively fixed with… Each tension spring has a hook fixed to its end. The hook extends upwards through the nozzle for entry and exit, and has a buckle hinged at the top. The buckle can be inserted into the hook to form a closed structure. The closed structure can be intermittently inserted into the nozzle. The buckle is made of magnetic material, and the hook is made of magnetically attracted material. When the buckle and hook form a closed structure, they can magnetically attract each other. The rear of the hook is rotatably connected to a roller that rolls and rubs against the nozzle. A handle is fixed to the upper rear of the buckle.

[0011] Based on the above technical solution, the clamping mechanism includes a connector, a socket, a rubber ring, and a locking mechanism. The two auxiliary swing arms are respectively hinged to the left and right of the connector. The two connectors are respectively passed through by the sockets on the left and right, and the ends that are far apart from each other are respectively fixed with connecting nozzles. The two connecting nozzles are respectively connected to the two sockets. The inner walls of the two sockets are respectively fitted with rubber rings. The two ends of the nozzle are respectively fixedly connected to rigid inserts. The two inserts are detachably connected to the two sockets. The rubber ring is sealed and fitted to the outer circumferential wall of the insert. The two connectors are respectively equipped with locking mechanisms for controllable locking of the nozzle.

[0012] Based on the above technical solution, the locking mechanism includes a pressing frame, a compression spring, and insert plates. The pressing frame is slidably connected to the insert seat, and a compression spring is fixed between the pressing frame and the insert seat. The pressing frame tends to slide backward under the elastic repulsive force of the compression spring. Insert plates are fixed at the upper and lower parts of the pressing frame, and the insert plates slide back and forth with the pressing frame and the insert seat. The nozzle includes a tube body, a limiting cylinder, a limiting plate, and a limiting groove. The tube body is made of a flexible material and can be bent freely. The water mist sprayed by the atomizing element penetrates the rear of the tube body. The atomizing element is an atomizing nozzle or atomizing hole. Each atomizing element is relative to the tube body along... The tubes are arranged axially, with limiting cylinders fixed to the outer walls of both ends. Vertical limiting plates are fixed to the upper and lower ends of the outer walls of the two limiting cylinders. The opposite ends of the two limiting cylinders are fixedly connected to and communicate with the two insertion tubes. Each limiting plate has a limiting groove extending through it. The limiting plate and the limiting cylinder can be detached and inserted into the insertion hole to match the insertion tube. The insertion plate can be inserted into the limiting groove under the elastic repulsive force of the compression spring. When the pressing frame is manually pressed forward, the insertion plate can be released from the limiting groove. The nozzle can still be installed with the clamping mechanism after rotating half a circle circumferentially. The insertion seat is made of transparent material.

[0013] Based on the above technical solution, the moving mechanism includes a trolley, a water tank, a placement seat, a handle, a soft pad, a slot, a strap, Velcro fasteners, and Velcro fasteners. The controller and the water pump are fixed to the trolley, and the trolley is also fixed with a water tank. The water pump's pumping pipe is connected to the inner cavity of the water tank through a pipe. The front of the support frame is detachably and securely fitted with a placement seat. A longitudinal handle is fixed inside the placement seat, and a soft pad is fitted and fixed to the upper part. A slot is provided on the left front of the placement seat, and a strap is installed on the right front. Velcro fasteners and Velcro fasteners are fixed to the right end of the strap. The strap can pass through the slot and bend to achieve the fastening of the Velcro fasteners and Velcro fasteners.

[0014] Based on the above technical solution, the moving mechanism also includes a robotic arm. The trolley is equipped with the robotic arm, and the execution end of the robotic arm is detachably and fastened to the front of the support frame.

[0015] Compared with the prior art, the present invention has the following advantages: When using the present invention, due to the height difference in the clamping mechanism, there is also a height difference between the two ends of the nozzle. When the two swing arms swing away from each other, the clamping mechanism can pull the nozzle to tautness. At this time, the moving mechanism drives the support frame to move up and down, while simultaneously controlling the water pump to draw ozone water to supply the nozzle, thus achieving large-area planar coverage spraying. Conversely, when the swing arms swing closer together, the middle of the nozzle droops and relaxes. At this time, the middle of the handle rotates half a turn along the plane, and then the elastic pulling mechanism is used to install it on the nozzle, allowing for elastic pulling... The structure forms a spiral, which can be used to attach the stem or fruit to the front of the spiral. Then, the moving mechanism drives the support frame to move up and down, and the water pump works to spray ozone water to sterilize the stem and fruit. This achieves complete coverage and sterilization of the rotating body without the need for frequent swinging at multiple angles, thus improving the sterilization effect and work efficiency. The left and right swing amplitude of the swing arm will adjust the front of the spiral structure accordingly, so as to adapt to rotating bodies such as stems or fruits with different outer diameters, making the spraying distance more suitable, thereby improving practicality and work efficiency.

[0016] By using the forward and reverse rotation of the No. 2 servo motor, the two main swing arms can move closer and further apart, thereby assisting in adjusting the left and right distance between the two secondary swing arms. This, in turn, helps adjust the inner diameter of the spiral structure to match rotating bodies such as stems or fruits of different sizes. This adjustment method allows the nozzle to be adjusted to a greater extent between the taut and spiral states, rather than simply relying on the left and right swing of the secondary swing arms. This can reduce the design length of the secondary swing arms to a certain extent and reduce the length of the part that protrudes backward, thereby improving the structural stability during operation.

[0017] Using a robotic arm to move the support frame is more time-saving and labor-saving than manual work, thus improving work efficiency. The placement seat can cooperate with the worker's arm. The worker holds the handle, sinks his arm into the soft pad inside the placement seat, and then passes the strap through the slot and uses the combination of Velcro and Velcro to fasten it, thus achieving the connection with the arm. This allows for spraying operations at various angles and positions along with the arm, improving the spraying effect. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-6As shown, an ozone atomizing sprayer for controlling powdery mildew in greenhouse crops includes a moving mechanism 1, a water pump 2, a controller 3, a support frame 4, swing arms 5, clamping mechanisms 6, a spray pipe 7, an atomizing element 8, and an elastic pulling mechanism 9. The moving mechanism 1 is equipped with the water pump 2, the controller 3, and the support frame 4. Swing arms 5 are mounted on both the left and right sides of the support frame 4. Clamping mechanisms 6 are mounted on the ends of the two swing arms 5 furthest from the support frame 4. The two swing arms 5 can controllably drive the two clamping mechanisms 6 to swing left and right respectively. The positions of the two clamping mechanisms 6 are [not specified]. At a height difference greater than the maximum outer diameter of the target crop stem, the two clamping mechanisms 6 jointly clamp a flexible nozzle 7. The nozzle 7 has multiple atomizing elements 8 that communicate with the outside world. The support frame 4 and the swing arm 5 are jointly equipped with an elastic pulling mechanism 9. The elastic pulling mechanism 9 is installed in a controllable manner to pull the nozzle 7 closer to the support frame 4 and the swing arm 5. The controller 3 is electrically connected to the water pump 2 and is connected to an external power source. The drain pipe of the water pump 2 is connected to the nozzle 7 through an excess flexible hose.

[0027] During use, due to the height difference of the clamping mechanism 6, there is also a height difference between the two ends of the nozzle 7. When the two swing arms 5 swing away from each other, the clamping mechanism 6 can pull the nozzle 7 to make it tend to straighten. At this time, the moving mechanism 1 drives the support frame 4 to move up and down, while controlling the water pump 2 to draw ozone water to supply the nozzle 7, thus achieving large-area planar coverage spraying. During this process, the elastic pulling mechanism 9 disengages from the nozzle 7. When the swing arms 5 are controlled to swing closer to each other, the middle part of the nozzle 7 droops and relaxes. At this time, the middle part of the handle is rotated half a turn along the front plane, and then the elastic pulling mechanism 9 is used to install the nozzle 7. Under the elastic pulling, a spiral structure is formed, and the rear part of the spiral structure separates from each other in the vertical direction. The structural feature of the rear part separating vertically makes the support frame 4 By rotating the spiral structure 90 degrees along the front plane, it can be inserted into the stem. Then, by rotating it 90 degrees in the opposite direction along the front plane, the front part of the spiral structure can be used to attach the stem. Subsequently, the moving mechanism 1 drives the support frame 4 to move up and down, and the water pump 2 works to spray ozone water to sterilize the stem. Alternatively, the spiral structure can be used to attach the spiral structure from bottom to top to sterilize the fruit. This achieves complete coverage and sterilization of the rotating body without the need for frequent swinging at multiple angles, improving the sterilization effect and work efficiency. The left and right swing amplitude of the swing arm 5 will cause the front part of the spiral structure to be adjusted accordingly, thereby adapting to rotating bodies such as stems or fruits with different outer diameters, making the spraying distance more suitable, thus improving practicality and work efficiency.

[0028] The swing arm 5 includes a support member 10, a secondary swing arm 11, and a servo motor 12. The support frame 4 has a support member 10 installed on each of its left and right sides. The two support members 10 are respectively hinged to the secondary swing arms 11 on the left and right sides. The two secondary swing arms 11 are respectively installed with the clamping mechanism 6. The two support members 10 are respectively equipped with servo motors 12. The rotation shafts of the two servo motors 12 are respectively fixed to the secondary swing arms 11. The rotation shafts of the two servo motors 12 are coaxial with the virtual hinge shafts of the secondary swing arms 11. The two servo motors 12 are respectively electrically connected to the controller 3. When the two servo motors 12 rotate, they can drive the two secondary swing arms 11 to swing left and right.

[0029] Furthermore, by controlling the forward and reverse rotation of the servo motor 12, the swing angle of the two swing arms 11 is adjusted, thereby using the elastic pulling mechanism 9 to elastically pull the nozzle 7 to change the size of the spiral structure.

[0030] The support member 10 includes a support base 13, a main swing arm 14, and a rotary drive mechanism 15. The left and right sides of the support frame 4 are each rotatably connected to a horizontal support base 13. The two support bases 13 are respectively equipped with main swing arms 14. The two main swing arms 14 are respectively hinged to the two auxiliary swing arms 11. The virtual rotation axis of the support base 13 is arranged horizontally from left to right. The support frame 4 is equipped with a rotary drive mechanism 15. The rotary drive mechanism 15 is used to controllably drive the support base 13 to rotate, thereby driving the main swing arms 14 to swing up and down. When the main swing arms 14 swing up and down, they drive the auxiliary swing arms 11 to swing up and down synchronously, thereby changing the height difference between the positions of the two clamping mechanisms 6.

[0031] Furthermore, by changing the height difference between the two clamping mechanisms 6, the pitch of the spiral structure can be altered to accommodate stems of varying thicknesses. When the spiral structure is interlocked with the stem, the two main swing arms 14 swing up and down to bring them closer together, thus reducing the pitch. This makes the spiral structure more ring-shaped, allowing it to move a wider range in the axial direction of the stem, resulting in a wider spray coverage, reduced omissions, and ultimately improved sterilization effect and work efficiency.

[0032] The rotary drive mechanism 15 includes a first servo motor 16, a first bevel gear 17, and a second bevel gear 18. The first servo motor 16 is fixed to the front of the support frame 4. The first bevel gear 17 is coaxially fixed to the rotating shaft of the first servo motor 16. The two support seats 13 are respectively fixed with second bevel gears 18. The second bevel gears 18 are coaxially arranged with respect to the virtual rotation axis of the support seat 13. The first bevel gear 17 meshes with the two second bevel gears 18. The first servo motor 16 has a braking function and is electrically connected to the controller 3. When the first servo motor 16 rotates forward and backward, it can drive the support seat 13 to rotate up and down in opposite directions through the meshing of the first bevel gear 17 and the second bevel gear 18.

[0033] Furthermore, by rotating the first servo motor 16 in both directions, the two support seats 13 are driven to rotate up and down in opposite directions, thereby quickly adjusting the vertical angle between the two main swing arms 14 and the auxiliary swing arm 11, that is, quickly adjusting the height difference between the clamping mechanisms 6, thereby improving work efficiency.

[0034] The support frame 4 is rotatably connected to a bidirectional lead screw 19. The left and right parts of the bidirectional lead screw 19 are symmetrically arranged and are rotatably connected to the support base 13 respectively. The bidirectional lead screw 19 is coaxial with the virtual rotation axis of the two support bases 13. The left and right parts of the bidirectional lead screw 19 are threadedly connected to two main swing arms 14 respectively. The two main swing arms 14 are slidably connected to the support base 13 respectively. The sliding direction of the two main swing arms 14 relative to the support base 13 is parallel to the axial direction of the bidirectional lead screw 19. The middle part of the bidirectional lead screw 19 is coaxially fixed. A third bevel gear 20 is fixed, and a second servo motor 21 with braking function is fixed at the bottom of the support frame 4. A fourth bevel gear 22 is fixed coaxially to the rotating shaft of the second servo motor 21. The fourth bevel gear 22 meshes with the third bevel gear 20. The second servo motor 21 is electrically connected to the controller 3. When the second servo motor 21 rotates forward and backward, it can drive the bidirectional lead screw 19 to rotate forward and backward through the fourth bevel gear 22 and the third bevel gear 20, thereby driving the two main swing arms 14 to slide closer and further apart along the support base 13.

[0035] Furthermore, by utilizing the forward and reverse rotation of the second servo motor 21, the two main swing arms 14 can move closer to each other and further away from each other, thereby assisting in adjusting the left and right distance between the two auxiliary swing arms 11, and subsequently assisting in adjusting the inner diameter of the spiral structure to match rotating bodies such as stems or fruits of different sizes. This adjustment method allows the nozzle 7 to be adjusted to a greater extent between the taut and spiral states, rather than simply relying on the left and right swing of the auxiliary swing arms 11. This can reduce the design length of the auxiliary swing arms 11 to a certain extent, reduce the length of the part that extends backward, and thus improve the structural stability during operation.

[0036] The elastic traction mechanism 9 includes an adjustment groove 23, a secondary traction rod 24, a hinge seat 25, a main traction rod 26, a tension spring 27, a hook 28, a buckle 29, a roller 52, and a handle 53. The secondary swing arm 11 extends vertically through the adjustment groove 23. The two adjustment grooves 23 are slidably connected to the secondary traction rod 24. The secondary traction rod 24 can slide laterally and swing left and right along the adjustment groove 23. The support frame 4 has a hinge seat 25 fixed at the rear. The main traction rod 26 is hinged to the left and right sides of the hinge seat 25. Tension springs are fixed to the ends of the main traction rod 26 and the secondary traction rod 24 in their respective extension directions. 27. Each of the tension springs 27 has a hook 28 fixed to its end. The hook 28 extends upward through the nozzle 7 and is hinged at the top to a buckle 29. The buckle 29 can be inserted into the hook 28 to form a closed structure together. The closed structure can be intermittently inserted into the nozzle 7. The buckle 29 is made of magnetic material, and the hook 28 is made of a material that can be magnetically attracted. When the buckle 29 and the hook 28 form a closed structure together, they can be magnetically attracted. The rear of the hook 28 is rotatably connected to a roller 52 that rolls and rubs against the nozzle 7. A handle 53 is fixed to the upper rear of the buckle 29.

[0037] Furthermore, by manually turning the handle 53 backward, the buckle 29 can be disengaged from the hook 28, thus opening the through-hole at the top of the hook 28 to facilitate the entry and exit of the nozzle 7. Once the nozzle 7 is in place, turning the handle 53 in the opposite direction will restore the buckle 29 to the hook 28 and achieve magnetic attraction, thus achieving a stable connection with the nozzle 7 and preventing accidental disengagement. The tension spring 27 can expand and pull the front and left and right parts of the spiral structure, making the spiral structure more stable and easier to cooperate with the longitudinal stem. The use of the roller 52 can roll and rub against the nozzle 7, thereby reducing wear.

[0038] The clamping mechanism 6 includes a connector 30, a socket 31, a rubber ring 33, and a locking mechanism 35. The two auxiliary swing arms 11 are respectively hinged to the connector 30 on the left and right. The two connectors 30 are respectively passed through the socket 31 on the left and right, and the ends that are far apart from each other are respectively fixed with connecting nozzles 32. The two connecting nozzles 32 are respectively connected to the two sockets 31. The inner walls of the two sockets 31 are respectively fitted and fixed with rubber rings 33. The two ends of the nozzle 7 are respectively fixed and connected with rigid inserts 34. The two inserts 34 are detachably connected to the two sockets 31. The rubber rings 33 are sealed and fitted to the outer circumferential walls of the inserts 34. The two connectors 30 are respectively equipped with locking mechanisms 35 for controllable locking of the nozzle 7.

[0039] The locking mechanism 35 includes a pressing frame 36, a compression spring 37, and a insert plate 38. The pressing frame 36 is slidably connected to the insert seat 30. The pressing frame 36 and the insert seat 30 are both fixed with the compression spring 37. The pressing frame 36 has a tendency to slide backward under the elastic repulsive force of the compression spring 37. The upper and lower parts of the pressing frame 36 are each fixed with an insert plate 38. The insert plate 38 follows the pressing frame 36 and is slidably connected to the insert seat 30. The nozzle 7 includes a tube body 54, a limiting cylinder 39, a limiting plate 40, and a limiting groove 41. The tube body 54 is made of flexible material and can be bent freely. The water mist sprayed by the atomizing element 8 passes through the rear of the tube body 54. The atomizing element 8 is an atomizing nozzle or atomizing hole. Each of the atomizing elements 8 is relative to the tube body 54 along... The tube body 54 is arranged axially. The outer walls of the two ends of the tube body 54 are fixed with limiting cylinders 39. The upper and lower ends of the outer walls of the two limiting cylinders 39 are respectively fixed with vertical limiting plates 40. The opposite ends of the two limiting cylinders 39 are fixedly connected to and communicate with the two insertion tubes 34. Each limiting plate 40 passes through a limiting groove 41. The limiting plate 40 and the limiting cylinder 39 can be detached from the insertion hole 31 and match the insertion tube 34. The insertion plate 38 can be inserted into the limiting groove 41 under the elastic repulsive force of the compression spring 37. When the pressing frame 36 is manually pressed forward, the insertion plate 38 can be released from the limiting groove 41. The nozzle 7 can still be installed with the clamping mechanism 6 after being rotated half a circle around the circumference. The insertion seat 30 is made of transparent material.

[0040] Furthermore, when large-area planar spraying is required, the atomizing element 8 is directed to spray backward, avoiding forward spraying that could affect other structures or personnel. When spraying rotating objects such as stems and fruits, the pressing frame 36 is manually pressed to release the insertion plate 38 from the limiting groove 41, causing the spray pipe 7 to disengage from the insertion hole 31. The pipe is then rotated half a turn forward and backward before being re-inserted into the insertion hole 31. Specifically, the pressing frame 36 is manually pressed again to release the insertion pipe 34 from the limiting cylinder 3. Insert the nozzle 7 into the insertion hole 31, and then release the pressure on the pressing bracket 36 to restore the insertion of the insert plate 38 into the limiting groove 41. This prevents the nozzle 7 from accidentally disengaging from the clamping mechanism 6. At this time, the atomizing element 8 sprays towards the inside of the spiral structure, directly facing the surface of rotating bodies such as stems or fruits, thereby achieving spraying and covering operations. This avoids excessive spraying outwards and affecting other mechanisms or personnel, while reducing unnecessary waste of ozone water. The transparent insert seat 30 makes it easy to observe the position of the internal limiting cylinder 39 and limiting plate 40 to determine whether it is inserted correctly.

[0041] The moving mechanism 1 includes a trolley 42, a water tank 43, a placement seat 44, a handle 45, a soft pad 46, a through slot 47, a strap 48, Velcro 49, and Velcro 50. The controller 3 and the water pump 2 are fixed to the trolley 42. The trolley 42 is also fixed to the water tank 43. The water pump 2's pump pipe is connected to the inner cavity of the water tank 43 through a pipe. The support frame 4 has a detachable and securely mounted placement seat 44 at its front. The placement seat 44 has a longitudinal handle 45 fixed inside, and a soft pad 46 is fixedly attached to its upper part. The placement seat 44 has a through slot 47 at its left front and a strap 48 installed at its right front. The right end of the strap 48 is fixed with Velcro 49 and Velcro 50. The strap 48 can pass through the through slot 47 and bend to achieve the hook and loop fastening of Velcro 49 and Velcro 50.

[0042] Furthermore, the placement seat 44 can be used in conjunction with the operator's arm. The operator holds the handle 45, sinks their arm into the soft pad 46 inside the placement seat 44, and then passes the strap 48 through the slot 47 and uses the Velcro and Velcro 49 to fasten it, thus achieving the connection with the arm. This allows for spraying operations at various angles and positions along with the arm, improving the spraying effect. The trolley 42 facilitates the movement of the water tank 43, controller 3, and water pump 2, and stores ozone water in the water tank 43, thereby facilitating spraying and sterilization operations.

[0043] The moving mechanism 1 also includes a robotic arm 51, which is mounted on the trolley 42. The execution end of the robotic arm 51 is detachably fastened to the front of the support frame 4.

[0044] Furthermore, the placement seat 44 is removed, and then the end of the robotic arm 51 is fastened to the front of the support frame 4. The robotic arm 51 is used to move the support frame 4, which is more time-saving and labor-saving than hand-held work, thereby improving work efficiency. Therefore, the controller 3 here is selected from the appropriate industrial control computer for control operations.

[0045] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
