Description

Technical Field

[0001] This invention relates to the field of tobacco cultivation technology, and in particular to a modular control tobacco pesticide spraying machine and its usage method. Background Technology

[0002] Tobacco is an annual herbaceous plant belonging to the genus Nicotiana in the family Solanaceae. In addition to being smoked by humans, it also has various medicinal uses. During the tobacco cultivation process, pests and diseases exist in the seedbed stage, field stage, and early maturity stage. Therefore, it is necessary to carry out targeted pesticide spraying operations for different pests and diseases corresponding to different growth stages.

[0003] In modern tobacco cultivation, large-scale mechanized planting is mostly employed, often involving uniform planting, pesticide spraying, and harvesting across vast tobacco fields. However, there are also special cases, such as tobacco cultivation based on breeding practices, small-scale and scattered tobacco cultivation, and multi-variety classification planting. Such modular planting requires targeted and differentiated management. If existing intensive and large-scale pesticide spraying equipment is used, it is constrained by the planting scale, variety, and different growth cycles, making it inconvenient to flexibly adjust the spraying spacing and position during pesticide application. This results in many inconveniences during pesticide application, leading to low work efficiency, poor pesticide application effects, inaccurate pesticide application to the tobacco, and excessive waste. Summary of the Invention

[0004] The purpose of this invention is to provide a modular control tobacco pesticide spraying machine and its usage method, which can flexibly adjust the spraying position and spraying spacing to meet the pesticide spraying operation of different varieties and growth cycles of tobacco, ensure that the pesticide is evenly sprayed on the tobacco of the corresponding module, improve the convenience of spray planting, and avoid pesticide waste.

[0005] The present invention adopts the following technical solution:

[0006] A modular control type tobacco pesticide sprayer includes a liquid storage tank, a delivery pump mounted on the liquid storage tank, and multiple delivery pipes connected to the delivery pump. Each delivery pipe is rotatably connected to a corresponding spray pipe. The multiple spray pipes are arranged parallel to each other on a hanger, and the spacing between the spray pipes can be adjusted along the hanger. The hanger is movably mounted on a transverse track, which is slidably mounted on a support beam and arranged perpendicular to the support beam.

[0007] Preferably, the hanger is a frame structure composed of support pipes arranged horizontally and vertically. Two support pipes arranged perpendicular to the spray pipe are rotatably fitted with threaded rods driven by a motor. The threaded rods have symmetrically arranged reverse threads, and a support sleeve connected to the support pipe is movably mounted in the middle. Sliding sleeves are respectively matched on the threaded rods on both sides of the support sleeve, and the sliding sleeves are slidably connected to a limiting rod mounted on the hanger. A through groove is opened at the bottom of the support pipe where the threaded rods are mounted, and the spray pipe passes through the through groove via a connector and connects to the sliding sleeve and the support sleeve.

[0008] Preferably, the motor is a dual-axis motor, which is mounted on the support tube in the direction perpendicular to the threaded screw. Both ends of the dual-axis motor are connected to a drive shaft, and a drive bevel gear is mounted on the drive shaft. Each end of the threaded screw is provided with a driven bevel gear that meshes with the drive bevel gear.

[0009] Preferably, the sliding sleeve includes a threaded sleeve that is matched and connected to the threaded screw, and a sliding block is provided on the outside of the threaded sleeve. The threaded sleeve and the sliding block are rotatably connected. A clutch is provided on the sliding block to restrict the threaded sleeve. A transmission member is provided between the threaded sleeve and the limiting rod, and between the support sleeve and the limiting rod. The limiting rod is rotatably disposed in the support tube. A push plate is provided at the bottom end of the sliding block and sleeved on the limiting rod. The push plate is movably connected to the transmission member. The connecting member includes a winding wheel, and a lifting rope is provided on the winding wheel. The lifting rope is connected to the spray pipe. The winding wheels on both sides are coaxially connected to the threaded sleeves at the corresponding ends. The winding wheel in the middle is coaxially connected to the transmission member.

[0010] Preferably, the transmission component includes a transmission pulley disposed on the limiting rod, the transmission pulley having a limiting groove, and the limiting rod having a limiting protrusion matching the limiting groove; the transmission pulley is rotatably disposed on the push plate; the transmission pulley is connected to a drive pulley via a transmission belt, the drive pulleys on both sides being coaxially disposed at one end of the threaded sleeve, and the drive pulley in the middle being rotatably disposed on the support sleeve.

[0011] Preferably, the clutch includes a drive block elastically disposed within the sliding block, a limiting groove for placing the drive block is provided on the threaded sleeve, a drive shaft is provided on the drive block, an adjusting plate is slidably disposed on the sliding block in a direction perpendicular to the drive block, and a V-shaped groove is provided on the adjusting plate; in the initial state, the drive shaft is located at the bottom of the groove.

[0012] Preferably, limit plates are adjustablely provided on the threaded screws on both sides of the support sleeve.

[0013] Preferably, a support sleeve is provided on the outside of the spray pipe, and a connection port is provided in the middle of the support sleeve. The two ends of the connection port are connected to the spray pipe through retractable hoses. Mounting sleeves are movably provided at both ends of the support sleeve, and the spray pipe is connected to the suspension rope through the mounting sleeves.

[0014] Preferably, each of the support sleeves is provided with a bearing plate on both the upper and lower sides, and an adjustment groove is provided on the bearing plate along its length. A screw is provided in the adjustment groove, the bottom end of the screw is slidably connected to the support sleeve, and a locking screw sleeve is provided at the top end of the screw.

[0015] A method for using a modular control type tobacco pesticide sprayer includes the following steps: S1 Preparation of pesticide solution: turn on the delivery pump to deliver water into the liquid storage tank, and add pesticide into the liquid storage tank to complete the preparation of pesticide solution;

[0016] S2 equipment debugging: Adjust the spacing of the spray pipes according to the density of tobacco planting in different modules;

[0017] S3 pesticide spraying: By controlling the movement of the transverse track on the support beam and the movement of the hanger on the support beam, the tobacco spraying operation between different modules can be realized.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, by sliding a transverse track on the support beam and a hanger sliding on the transverse track, can drive the spray pipe to move in the vertical direction in both the longitudinal and transverse directions, thereby meeting the pesticide spraying operation between different modules, improving the flexibility of the spraying operation, requiring minimal manual intervention for adjustment, making the operation simple and quick, and achieving high spraying efficiency; the spacing of the spray pipes can be adjusted, allowing spraying of different varieties or growth stages of tobacco in different modules, ensuring that the pesticide is evenly sprayed on the tobacco leaves, reducing waste caused by pesticide spillage on the ground and the adverse effects on the application effect.

[0019] Furthermore, in this invention, the clutch component can restrict the threaded sleeve, causing the threaded sleeve and sliding block to move synchronously along the length of the threaded screw. Alternatively, when the threaded sleeve moves to one end of the threaded screw, the clutch component can contact the inner wall of the support tube, the limiting plate, or the side wall of the support sleeve at one end of the threaded screw to release the restriction on the threaded sleeve, allowing the threaded screw to drive the threaded sleeve to rotate synchronously. This, in turn, drives the transmission component to rotate synchronously, thereby enabling the hanging rope in the connecting component to be wound or released, satisfying the height adjustment operation of the spray pipe and further improving the accuracy of drug spraying. In addition, the optimized design of the clutch component, transmission component, and connecting component also allows for simultaneous adjustment of the horizontal position and height of the spray pipe under the drive of the threaded screw, optimizing the structure of the entire spraying machine, enhancing the practicality of this invention, and simplifying the control procedure during spraying operations.

[0020] Furthermore, the movable design of the sleeves at both ends of the support sleeve allows for rotation and adjustment, thereby flipping the spray pipes inside. This enables pesticide spraying onto the back of tobacco leaves, allowing for precise application of pesticides to designated locations based on different pests and diseases, ensuring effective application. The movable design of the external support plates allows multiple support plates to be adjusted to a perpendicular position to the support sleeve, placing the support sleeve within the space defined by the upper and lower support plates in each group. This creates a vertical support frame using the support sleeve and support plates, providing a lifting support platform for subsequent fertilizer application or the placement of harvested items, enriching the functionality of the invention and enhancing its practicality.

[0031] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0032] like Figures 1 to 10 As shown, the modular control tobacco pesticide sprayer of the present invention includes a liquid storage tank 1 for storing pesticide solution, with a dosing port at the top and a motor-driven stirring paddle inside to fully mix the pesticide with water; a water pump 2 connected to a water source is installed on one side of the liquid storage tank 1 to deliver water for mixing and diluting the pesticide into the liquid storage tank 1; a delivery pump 3 is installed on the liquid storage tank 1 to pump and transport the mixed pesticide solution in the liquid storage tank 1; the delivery pump 3, the water pump 2, and the stirring paddle can all be controlled by a control device installed on one side; multiple delivery pipes 4 are connected to the delivery pump 3, and the multiple delivery pipes 4 are rotatably connected to corresponding spray pipes 5, and the four delivery pipes do not interfere with each other, and each All four infusion tubes are of sufficient length to meet the spraying requirements. These four tubes can be connected via multiple hanging rings using existing technology, allowing for extension and retraction as spraying progresses. Multiple spray pipes 5 are arranged parallel to each other on the hanger, and the spacing between them can be adjusted along the hanger to meet the spraying needs of different tobacco varieties or growth stages. For example, in the early stages of growth, the spacing between tobacco leaves is relatively sparse, or different varieties may have different planting densities due to varying growth space requirements. Therefore, the adjustable setting of the spray pipes 5 facilitates adjustment of their spacing to allow for pesticide spraying operations on tobacco varieties and growth stages in different modules, ensuring uniform pesticide application and reducing pesticide waste.

[0033] In this invention, the hanger is movably mounted on the transverse track 6, which is slidably mounted on the support beam 7 and arranged perpendicularly to it. At least two support beams are symmetrically arranged, each supported on both sides of its bottom by support columns 8, which are fixed at the four corners of the planting area. If the planting area is large, multiple support beams 7 can be installed to prevent the transverse track 6 from having an excessively large span, resulting in insufficient support in the middle and affecting the overall structural strength. Both the support beam 7 and the transverse track 6 are I-shaped structures, with motor-driven moving wheels installed in the grooves on both sides. The moving wheels on both sides are connected by a U-shaped lifting plate 9. The hanger is located at the bottom of the lifting plate 9. By controlling the movement and adjustment of the transverse track 6 along the length of the support beam 7 and the hanger along the length of the transverse track 6, the spray pipe 5 can be moved laterally and longitudinally, allowing the sprayer to be flexibly moved to different modules for spraying operations, improving operational convenience. Since the support beam 7 is installed above the maximum height of the tobacco during its maturity period, the spraying operation is less restricted, resulting in greater operational flexibility.

[0034] Furthermore, in this invention, the hanger is a frame structure composed of support pipes 10 arranged horizontally and vertically. Within the two support pipes 10 arranged perpendicularly to the spray pipe 5, a threaded rod 11 driven by a motor is rotatably installed. A support sleeve 12 is installed within the support pipe 10 at a position corresponding to the middle of the threaded rod 11. The support sleeve 12 has an I-shaped structure, and the middle part of the threaded rod 11 is a smooth rod structure, rotatably connected to the support sleeve 12. Symmetrical reverse threads are provided on the threaded rods 11 on both sides of the support sleeve 12. Each threaded rod 11 is fitted with a sliding sleeve, which is slidably connected to a limiting rod 13 mounted on the hanger. The limiting rod 13 can limit the sliding sleeve to ensure that the circular motion is converted into linear motion under the rotation of the threaded rod 11, allowing the sliding sleeve to move along the length of the threaded rod 11 and preventing it from flipping synchronously under the rotation of the threaded rod 11. The bottom of the support tube 10 for the threaded rod 11 is provided with a through groove, and the spray pipes 5 at different positions are connected to the corresponding sliding sleeves and support sleeves 12 through the through groove via connectors. Preferably, three spray pipes 5 are provided. The middle spray pipe 5 is connected to the support sleeve 12 via a connector, and the spray pipes 5 on both sides are connected to the sliding sleeves via connectors. This allows the spray pipes 5 to move in opposite directions or towards each other as the sliding sleeves on both sides move away from each other under the rotation of the threaded rod 11, thereby adjusting the spacing of the spray pipes 5 to meet different drug spraying operations.

[0035] The motor driving the threaded screw 11 is a dual-axis motor 15, which is mounted on a support tube 10 perpendicular to the threaded screw 11. Both ends of the dual-axis motor 15 are connected to drive shafts located within the corresponding support tubes 10. Each drive shaft has a drive bevel gear, and each threaded screw 11 has a driven bevel gear 14 at its end. The driven bevel gear 14 extends from the support tube 10 containing the threaded screw 11 and is located within the support tube 10 containing the drive rod, meshing with the drive bevel gear. Driven by the dual-axis motor 15, the threaded screws 11 on both sides of the hanger can be driven synchronously. This also reduces the need for excessive installation of drive components, thus minimizing debugging and maintenance issues and enhancing the practicality of the invention.

[0036] In this invention, the sliding sleeve includes a threaded sleeve 16 that is matched and connected to the threaded screw 11. A sliding block 17 is provided on the outside of the threaded sleeve 16, and the threaded sleeve 16 and the sliding block 17 are rotatably connected. A clutch is provided on the sliding block 17 to restrict the threaded sleeve 16. Transmission components are provided between the threaded sleeve 16 and the limiting rod 13, and between the support sleeve 12 and the limiting rod 13. The limiting rod 13 is rotatably disposed inside the support tube 10. A sleeve fitted on the limiting rod 13 is provided at the bottom end of the sliding block 17. Push plate 18, push plate 18 is movably connected to the corresponding transmission component; the connecting component includes take-up reel 19 and suspension rope 20 set on take-up reel 19, the take-up reels 19 at both ends are coaxially connected to one end of threaded sleeve 16, the take-up reel 19 in the middle is coaxially fixedly connected to the transmission component on the support sleeve 12, and the suspension rope 20 is connected to the spray pipe 5; wherein the take-up reels 19 on both sides are sleeved outside the threaded screw 11, and the take-up reel 19 in the middle is sleeved outside the support sleeve 12. During operation, driven by the threaded screw 11, the threaded sleeve 16 and the sliding block 17 move along its length. When the sliding block 17 moves to the end of the threaded screw 11, the clutch contacts the inner wall of the support tube 10. At this time, as the threaded screw 11 continues to run, the clutch will release the restriction on the threaded sleeve 16 under the thrust of the threaded screw 11. The threaded sleeve 16 will then rotate synchronously with the threaded screw 11, thereby driving the transmission component and the limiting rod 13 to rotate, thus realizing the synchronous rotation of multiple winding wheels 19, completing the winding or releasing operation of the hanging rope 20, thereby satisfying the synchronous adjustment operation of the height of multiple spray pipes 5. Different height spraying operations can be carried out according to different growth cycles and varieties of tobacco, further ensuring the spraying effect of the drug. The structure is simple and highly practical.

[0037] Specifically, the transmission component includes a transmission pulley 21 mounted on the limiting rod 13. The inner wall of the transmission pulley 21 is provided with a limiting groove. The limiting rod 13 is provided with a limiting protrusion 22 that matches the limiting groove, so as to ensure that the transmission pulley 21 can drive the limiting rod 13 to rotate synchronously when it rotates. The transmission pulleys 21 located on both sides are rotatably mounted on the push plate 18 through bearings, and the limiting grooves on the transmission pulleys 21 on both sides are in sliding contact with the limiting protrusions 22, so that the push plate 18 and the transmission pulleys 21 can move synchronously along the limiting rod 13 as the sliding block 17 moves. The transmission pulley 21 connected to the drive pulley 23 mounted on the support sleeve 12 has a fixed position and does not need to be adjusted, so it is preferable to fix the transmission pulley 21 here to the limiting rod 13. The transmission pulley 21 is connected to the drive pulley 23 through the transmission belt 24. The drive pulleys 23 located on both sides are coaxially mounted at one end of the threaded sleeve 16, and the drive pulley 23 located in the middle is rotatably mounted on the support sleeve 12. During operation, when the clutch releases the restriction on the threaded sleeve 16, the threaded sleeve 16 rotates under the drive of the threaded screw 11. At the same time, the threaded sleeve 16 drives the drive pulley 23 connected to it to rotate, which in turn drives the driven pulley and the limit rod 13 to rotate under the drive of the transmission belt 24. This, in turn, drives the drive pulley 23 and the winding pulley 19 on the support sleeve 12 to rotate, which can ensure that the three winding pulleys 19 can simultaneously wind up or release the suspension rope 20, thus ensuring the lifting and lowering of the spray pipe 5 during use.

[0038] The clutch component of this invention includes a drive block 25, a sliding block 17 with a cavity inside, the drive block 25 being disposed within the cavity, and a guide rod 26 at its top end, the top end of the guide rod 26 movably protruding from the top end of the sliding block 17. A return spring 27 is sleeved on the outside of the guide rod 26, located between the inner wall of the cavity and the drive block 25. The drive block 25 is elastically disposed within the cavity of the sliding block 17 by the return spring 27. A limiting groove 28 for placing the drive block 25 is provided on the threaded sleeve 16. A drive shaft 29 is vertically disposed on the drive block 25. An adjusting plate 30 is slidably disposed on the sliding block 17 in a direction perpendicular to the drive block 25. The adjusting plate 30 is provided with a V-shaped groove 31; in the initial state, the drive shaft 29 is located at the bottom of the groove 31. The length of the adjusting plate 30 is greater than the sum of the lengths of the take-up wheel 19, the drive pulley 23, and the threaded sleeve 16. This is so that during operation, as the sliding block 17 moves, the adjusting plate 30 first contacts the obstacle at one end of the threaded screw 11. With the continuous rotation of the threaded screw 11, the adjusting plate 30 is pushed to move horizontally, thereby causing the drive shaft 29 to slide in the slide groove 31. This causes the drive block 25 to move upward and disengage from the limiting groove 28, releasing the restriction on the threaded sleeve 16. At this time, the threaded sleeve 16, no longer restricted, will rotate synchronously with the threaded screw 11, thereby driving the take-up wheel 19 and the drive pulley 23 to rotate, completing the height adjustment operation of the spray pipe 5. It is worth noting that during the idling of the threaded sleeve 16, as the limiting groove 28 moves to the position corresponding to the driving block 25, the driving block 25 will fall into the limiting groove 28 to form a restriction. However, as the threaded screw 11 continues to rotate in the same direction, at the moment the driving block 25 falls, the sliding block 17 will drive the adjusting plate 30 to move continuously toward the obstacle. The adjusting plate 30 will be continuously pushed up, losing its restriction on the threaded sleeve 16, thus ensuring that the threaded sleeve 16 rotates synchronously with the threaded screw 11. When the threaded screw 11 rotates in the reverse direction, the threaded sleeve 16 rotates to the position corresponding to the limit groove 28 and the drive block 25. The drive block 25 then falls to limit the threaded sleeve 16. Since the threaded screw 11 rotates in the reverse direction, the adjusting plate 30 will move away from the obstacle. At this time, the threaded sleeve 16 will stop rotating due to the restriction and will move in the opposite direction synchronously with the sliding block 17 until it contacts the obstacle in the opposite direction. The drive block 25 will be lifted again to release the restriction on the threaded sleeve 16. The threaded sleeve 16 will drive the winding wheel 19 and the drive pulley 23 to rotate, completing the winding operation of the hoisting rope 20.

[0039] In this embodiment, the obstacle can be the side wall of the support tube 10 or the side wall of the support sleeve 12. In order to further improve the practicality of the present invention and enrich its functions, the present invention can also adjust the limit plate 32 on the threaded screw 11 on both sides of the support sleeve 12. By adjusting the distance between the limit plate 32 and the support sleeve 12, the distance that the sliding block 17 moves can be adjusted, thereby further enhancing the flexibility of the present invention. Preferably, a ball screw 33 is rotatably mounted parallel to the threaded screw 11 within the support tube 10 above it. A sliding block is matched on the ball screw 33, and a limiting plate 32 is provided outside the sliding block. The bottom of the limiting plate 32 is sleeved onto the threaded screw 11 below. A main bevel gear 34 extends from the end of the ball screw 33 away from the driven bevel gear 14 from within the support tube 10. The main bevel gear 34 extends into the support tube 10 at the corresponding end. A dual-axis motor 15 is mounted on the support tube 10 at the corresponding end. The dual-axis motor 15 has drive shafts at both ends, and a secondary bevel gear meshing with the main bevel gear 34 is provided at the end of the drive shaft. The dual-axis motor 15 drives the drive shafts on both sides to rotate, which can realize the synchronous adjustment of the limiting plates 32 on both sides of the hanger, ensuring the horizontality of the position of the spray pipe 5 after movement.

[0040] Furthermore, in this invention, a support sleeve 35 is also fitted around the outside of the spray pipe 5. A connection port 36 is provided in the middle of the support sleeve 35, and the connection port 36 is arranged through the left and right sides. The two ends of the connection port 36 are connected to the spray pipe 5 through retractable hoses 37, which facilitates pulling the spray pipe 5 out a certain distance during use to adjust the spray range, or storing the spray pipe 5 after use to protect it from corrosion caused by external adverse factors when not in use. A magnetic absorbing plate 38 is provided on the spray pipe 5 located inside the support sleeve 35, and annular magnetic absorbing plates 39 are provided on both sides of the connection port 36 and near the end of the support sleeve 35. The magnetic absorbing plate 38 and the magnetic absorbing plate 39... Adsorption ensures the stability of the spray pipe 5 during storage and extended use. In this invention, spray heads 40 are spaced apart along the length of both the front and rear sides of the spray pipe 5. The spray heads 40 are positioned slightly below the central axis of the spray pipe 5, and are arranged in a V-shape to ensure the spray coverage area. The support sleeve 35 has a receiving groove 41 along its length for the spray heads 40 to pass through. Since the spray pipe 5 will not be completely pulled out of the support sleeve 35, but only a short distance for appropriate extension, the receiving groove 41 ensures normal spraying. At this time, notches are also provided on both sides of the annular magnetic chuck 39 corresponding to the receiving groove 41 to avoid obstructing the movement of the spray heads 40. The spray heads 40 do not protrude from the receiving groove 41, providing a certain degree of protection for the spray heads while ensuring normal spraying.

[0041] The support sleeve 35 is also movably fitted with mounting sleeves at both ends, and the spray pipe 5 is connected to the suspension rope 20 through the mounting sleeves. The movable connection between the support sleeve 35 and the mounting sleeves facilitates the rotation and adjustment of the support sleeve 12, thereby causing the spraying direction of the spray pipe 5 to be reversed. Since the infusion pipe 4 is rotatably connected to the end of the spray pipe 5, the reversal of the support sleeve 35 will not affect it. The reversal of the spray pipe 5 enables the spraying of pesticides on the back of tobacco leaves to meet the control needs of different pests and diseases. Specifically, the mounting sleeve includes a collar 42, with arc-shaped clamping plates 43 fixedly connected to the upper and lower ends of the collar 42. The support sleeve 35 is movably disposed within the clamping plates 43; the distance between the upper and lower clamping plates 43 is not less than the opening height of the receiving groove 41 to avoid affecting the spraying of the spray head 40. To ensure the stability of the support sleeve 35 installed between the clamping plates 43, the present invention also provides a positioning sleeve on the outside of the two clamping plates 43 at one end; the positioning sleeve includes a connecting ring 44, and arc-shaped positioning pieces 45 are provided at the upper and lower ends of the connecting ring 44. Roller balls 46 are elastically provided on the inner surfaces of the arc-shaped positioning pieces 45. Arc-shaped limiting clamping plates 48 are provided on the clamping plates 43 through a buffer spring 47. The limiting clamping plates 48 are clamped on the outside of the support sleeve 35; a push rod 49 is provided on the limiting clamping plate 48. The buffer spring 47 is fixedly sleeved on the outside of the push rod 49. The push rod 49 is located in the positioning groove 50 opened on the clamping plate 43. A moving groove 51 communicating with the positioning groove 50 is opened on the clamping plate 43 in the horizontal direction. The positioning groove 50 and the moving groove 51 are preferably connected by a slope surface so that the roller balls 46 can move out of the positioning groove 50 and into the moving groove 51, thereby releasing the restriction on the support sleeve 35 and completing the rotation adjustment operation of the support sleeve 35. The connecting ring 44 can be intermittently set, with a slot reserved at the position corresponding to the receiving groove 41 to ensure that it does not obstruct or interfere with the spray head 40. When the support sleeve 35 needs to be adjusted, pull the connecting ring 44, which will cause the positioning plate 45 and the ball bearing 46 to move out of the positioning groove 50 and into the moving groove 51. Under the action of the buffer spring 47, the limiting clamp 48 drives the push rod 49 to move upward along the positioning groove 50. The limiting clamp 48 disengages from limiting the support sleeve 35. After rotating and adjusting it, the ball bearing 46 is pushed into the positioning groove 50 to apply a downward pushing force to the push rod 49. The limiting clamp 48 completes the limiting operation of the support sleeve 35. Among them, the ball bearing 46 pushes the positioning groove 50 to apply a downward pushing force to the push rod 49. The ball 46 is set on the support block 52, which is elastically set in the receiving sleeve 53 by a spring. The receiving sleeve 53 is set on the inner wall of the positioning clamp. When the ball 46 is inside the moving groove 51, the spring is in a compressed state. When the ball 46 is inside the positioning groove 50, the spring gradually extends under the action of the restoring force to push the downward push rod 49, so as to realize the positioning clamping of the limiting clamp 48 on the support sleeve 35. In this invention, a positioning sleeve can be set at one end of the mounting sleeve, which improves the convenience of operation.

[0042] Furthermore, in this invention, each support sleeve 35 is provided with a bearing plate 54 on both the upper and lower sides. An adjustment groove 55 is provided on the bearing plate 54 along its length direction. A screw 56 is movably arranged in the adjustment groove 55. The bottom end of the screw 56 is slidably connected to the support sleeve 35, and a locking screw sleeve is provided at the top end of the screw 56. The movable setting of the screw 56 inside the adjusting groove 55 allows the screw 56 to be used as an axis to adjust the bearing plate 54 to be perpendicular to the support sleeve 35. Then, moving the bearing plate 54 drives the screw 56 to slide on the support sleeve 35, achieving a parallel arrangement of the three bearing plates 54 at intervals. By moving the bearing plate 54 in a direction perpendicular to the spray pipe 5, the upper and lower bearing plates 54 of each group are clamped to the outside of the three support sleeves 35. Finally, the bearing plate 54 is fixed with a locking nut, which allows the bearing plate 54 and the support sleeve 35 to form a vertical and horizontal frame structure. When it is not necessary to spray pesticides, the frame structure formed by the two can be used to transport fertilizers or other materials, providing convenience for the transportation of raw materials during the planting process, further enriching the use function of the invention and enhancing its practicality. When spraying the pesticide solution is required, release the locking sleeve from restricting the screw 56 and the bearing plate 54, and adjust the bearing plate 54 to be parallel to the corresponding support sleeve 35 so that it presses against the support sleeve 35. To improve the tightness of the contact between the bearing plate 54 and the support sleeve 35, arc-shaped grooves 57 are provided in both the length and width directions of the bearing plate 54 to ensure a tight connection between the bearing plate 54 and the support sleeve 35 in a parallel or perpendicular state. To prevent the screw 56 from protruding and adversely affecting the transported goods, a countersunk groove is provided on the bearing plate 54, and an adjusting groove 55 is set in the countersunk groove. The countersunk groove can accommodate the screw 56 and the locking sleeve, preventing them from protruding from the surface of the bearing plate 54 and affecting subsequent transport operations.

[0043] In this invention, to ensure the stability of the frame composed of the bearing plate 54 and the support sleeve 35 during transportation, a limiting tube 58 is provided on the collar 42, and the lifting rope 20 is located inside the limiting tube 58; a receiving tube 59 is provided on the support tube 10 of the hanger, and the receiving tube 59 is connected to the push plate 18 so as to move with the rotation of the threaded screw 11; during the transportation process, after the items are placed, the limiting tube 58 can be stored in the receiving tube 59 by winding up the lifting rope 20, thereby limiting the frame structure composed of the bearing plate 54 and the support sleeve 35 and preventing the entire frame structure from shaking due to the swaying of the lifting rope 20 during transportation, effectively preventing items from falling. The bearing plate 54 and the support sleeve 35 are both made of metal materials with certain load-bearing capacity and strength, such as steel.

[0044] A method for using a modular control tobacco pesticide sprayer includes the following steps: S1 Preparation of pesticide solution: First, turn on the delivery pump 3 to deliver water to the liquid storage tank 1, and add pesticide to the liquid storage tank 1. Use the stirring paddle set on the liquid storage tank 1 to fully stir and mix the mixture to complete the preparation of the pesticide solution; S2 Equipment debugging: Adjust the spacing of the spray pipes 5 according to the density of tobacco planting in different modules; At the same time, the height of the spray pipes 5 can also be adjusted according to the differences in the varieties planted in different modules and the different growth cycles to spray the pesticide solution, ensuring that the pesticide solution is evenly applied to the tobacco leaves; S3 Pesticide solution spraying: By controlling the movement of the transverse track 6 on the support beam 7 and the movement of the hanger on the support beam 7, the spraying operation of tobacco between different modules can be realized. The control equipment can be manually controlled on-site using a remote control, or a programmed control system can be set up. A camera installed on the hanger and connected to the intelligent control equipment wirelessly can assist in the spraying operation. The operation can be fully automated by inputting the position of the specified module and the required spraying height and length into the control equipment. Since the control equipment and system use relatively mature equipment and software in the existing technology, the control equipment will not be described in detail.

[0045] This invention can be used not only for spraying pesticides but also for spraying liquid fertilizers and irrigation water, further expanding its application range. When solid fertilizers are being spread or goods are being transported during harvesting, the positions of the supporting plate 54 and the supporting sleeve 35 can be adjusted to form a vertical frame structure, providing a support platform for the goods. This invention allows for both vertical and horizontal height adjustment to meet the spraying needs of pesticides in different situations. Furthermore, moving the device above the tobacco prevents damage to the tobacco, improving the flexibility and safety of the adjustment.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
