Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a fully automatic human-machine separated plant protection high-pressure atomizer capable of spraying at multiple angles. Background Art

[0002] In modern agriculture, plant protection, referred to as plant protection, is one of the key factors to ensure crop health, growth and high yield, including pest control, weed control, healthy soil maintenance and ecological protection. In plant protection operations, high-pressure atomizers are usually used, which atomize the agent through the atomizing nozzle and spray it on the crops to prevent insect and disease disasters. This spraying method has the advantages of uniform spray coverage, reduced spraying volume, and less environmental pollution. The existing technology has the following defects: First, when some existing sprayers are used, their atomizing nozzles are prone to blockage, which is caused by uneven dissolution of the powder or impurities in the medicine. It takes a lot of time to clear the blockage, which is inconvenient to use; Second, the position of the existing atomizing nozzle is relatively fixed and cannot be flexibly adjusted, making it difficult for the sprayer to spray accurately and effectively when facing different crops, which is inconvenient to use.

[0003] In order to overcome defect one, prior art 1 (application number: 202221271954.2, Chinese patent with application date of 2022-05-25) discloses a remote high-pressure atomization device for use on a crop protection machine. Through the coordinated use of connecting rods, fan blades, pads, magnetic blocks, screening mesh covers and brushes, the sprayed medicine can be filtered first, thereby avoiding uneven dissolution of medicine powder or impurities in the medicine that cause blockage of the atomizing nozzle during spraying. This structure solves the above-mentioned defect one. In order to overcome the second defect, prior art 2 (application number: 202323398914.1, Chinese patent with application date of 2023-12-13) discloses a self-propelled spray boom sprayer for plant protection. By setting a second motor, an adjustment handle and an atomizing nozzle, the second motor is started to drive the screw to rotate, so that the slider drives the diversion pipe to slide up and down to adjust the position to cope with crops of different heights, improve the accuracy of spraying, reduce the difficulty of manual adjustment, and improve work efficiency. This structure solves the second defect mentioned above.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-Figure 6 As shown, the existing atomizer can only adjust the spraying height but cannot adjust the rotation angle, resulting in that the spraying range of the nozzle is still greatly limited. In order to solve this technical problem, the present embodiment discloses the following technical contents: it includes a movable base plate 1, and universal wheels 2 for overall movement are fixedly installed at the four corners of the bottom end of the movable base plate 1. The two side edges of the movable base plate 1 are upwardly tilted to prevent the movable base plate 1 from hitting the protrusions on the ground when the device moves, causing the medicine in the cartridge 3 to vibrate and spill out, and the top of the movable base plate 1 is fixedly connected to the cartridge 3.

[0027] A motor 4 is fixedly installed at the bottom of the movable bottom plate 1. The motor 4 drives a stirring mechanism to mix and stir the medicine in the cartridge 3. The stirring mechanism includes a stirring rod 5 fixedly connected to the output shaft at the top of the motor 4. The outer wall of the stirring rod 5 is fixedly connected to a plurality of groups of stirring blades 6 arranged vertically. The stirring rod 5 is driven by the motor 4 to drive the plurality of groups of stirring blades 6 to rotate, so as to stir the medicine in the cartridge 3 to reduce the phenomenon of medicine powder deposition.

[0028] A water pump 8 is fixedly installed on the top of the movable bottom plate 1. The left bottom of the cartridge 3 is connected to the input end of the water pump 8 through the medicine delivery pipe 7. The output end of the water pump 8 is connected to the two groups of atomizing nozzles 9 through the connecting hose 18, the lifting pipe 17, the diversion cross pipe 19, and the sleeve 20 in sequence.

[0029] The lifting tube 17 is movably arranged on the top of the movable base plate 1 through a height adjustment mechanism. The height adjustment mechanism includes a support frame 10 fixedly connected to the two ends of the top of the movable base plate 1. The inner side of the support frame 10 is rotatably connected to a first threaded rod 11. The outer side of the first threaded rod 11 is threadedly connected to a lifting slide 15. The lifting tube 17 is detachably installed on the lifting slide 15. The end wall of the lifting slide 15 is fixedly connected to a ring-shaped clamping seat 16. The bottom of the lifting tube 17 is clamped on the inner side of the clamping seat 16, and the bottom outer wall of the lifting tube 17 is formed with two vertically distributed annular protrusions, which are respectively clamped on the top and bottom of the clamping seat 16, so that the lifting tube 17 and the clamping seat can be realized. 16 is convenient for disassembly and assembly, and the lifting tube 17 can also be limited in the vertical direction to prevent it from moving at will and affecting the spraying effect. The bottom end of the first threaded rod 11 penetrates to the bottom of the mobile base plate 1 and is fixedly connected with a driven gear 12. The outer wall of the output shaft of the motor 4 is fixedly connected with a driving gear 13. The driving gear 13 and the two driven gears 12 are jointly meshed with a transmission gear 14. The transmission gear 14 is limitedly connected to the bottom end wall of the mobile base plate 1 through a limiting rotating member at the top, and its overall hollow structure is to reduce the overall weight of the device and facilitate movement while ensuring that the transmission gear 14 is stably meshed with the driven gear 12 and the driving gear 13.

[0030] By adopting the above technical solution, when the motor 4 drives the stirring mechanism to operate, the driving gear 13 rotates accordingly, and the two driven gears 12 are driven to rotate synchronously through the meshing transmission of the transmission gear 14, and the first threaded rod 11 rotates accordingly. The rotating first threaded rod 11 continues to drive the lifting slide 15 connected to the outer thread to rise and fall, and the lifting tube 17 rises and falls synchronously accordingly, thereby realizing the height adjustment of the atomizing nozzle 9.

[0031] An angle adjustment mechanism is provided between the two sleeves 20, and the angle adjustment mechanism includes a plurality of turning grooves 22 provided on the diversion transverse pipe 19. The sleeve 20 is a two-section pipe body and is symmetrically sleeved on the outer side of the diversion transverse pipe 19. The atomizing nozzle 9 is fixedly connected to the sleeve 20, and its water inlet end passes through the inner side of the diversion transverse pipe 19 through the turning groove 22. The two side walls of the diversion transverse pipe 19 are formed with protrusions for limiting the sleeve 20, and a sealing rubber ring is embedded on the inner side of the protrusion to prevent the liquid from leaking out through the gap between the protrusion and the sleeve 20. A connecting seat 21 is fixedly connected between the two sections of the pipe body of the sleeve 20. The end faces of the two connecting seats 21 that are close to each other are in an arc shape, and the outer wall is formed with a plurality of evenly distributed protruding teeth 23. The side wall of the movable bottom plate 1 is fixedly connected with symmetrically distributed racks 25 through a fixed plate 24, and the two racks 25 are respectively meshed with the corresponding protruding teeth 23.

[0032] Through the cooperation of the height adjustment mechanism and the angle adjustment mechanism, the spraying height and the spraying angle of the atomizing nozzle 9 can be adjusted at the same time, which effectively expands the spraying range of the device. When the height adjustment mechanism is in operation, the lifting tube 17, the connecting hose 18, the diversion cross pipe 19, and the sleeve 20 will be lifted and moved synchronously, and the connecting seat 21 and the protruding teeth 23 will be lifted and lowered accordingly. At this time, the protruding teeth 23 will rotate through the engagement with the fixed rack 25, and then the sleeve 20 will be driven to rotate around the diversion cross pipe 19 through the connecting seat 21, and the atomizing nozzle 9 will rotate along the turning groove 22, thereby realizing the adjustment of the spraying angle of the atomizing nozzle 9.

[0033] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above embodiment 1. Figure 7-Figure 8 As shown, the existing atomizer will waste undissolved medicine powder when filtering the medicine solution to prevent the nozzle from being blocked. In order to further solve this technical problem, the present embodiment discloses the following technical contents: a filter 26 is arranged inside the medicine delivery tube 7, and a medicine powder recovery mechanism is arranged outside the filter 26 to return the medicine powder that has not passed through the filter 26 and is attached thereto to the medicine cartridge 3 for stirring and dissolving again, so as to avoid wasting medicine powder. The medicine powder recovery mechanism includes a second threaded rod 28 that is limited and rotated at the inner center of the medicine delivery tube 7 through two fixing frames 27, and the filter 26 is threadedly connected to the second threaded rod 28. The filter plate 26 is in a columnar shell structure as a whole to accommodate more medicine powder. The right side of the second threaded rod 28 extends into the interior of the medicine cartridge 3 so that the medicine powder can be dissolved into the medicine solution by the stirring centrifugal force as much as possible. A rotating rod 29 is rotatably passed through the two end walls of the medicine delivery tube 7. The outer wall of the rotating rod 29 is fixedly connected to a first bevel gear 32. The side wall of the second threaded rod 28 is fixedly connected to a second bevel gear 33. The first bevel gear 32 is meshed with the second bevel gear 33. The outer wall of the rotating rod 29 is formed with circumferentially evenly distributed dial blocks 31. The dial blocks 31 are triangular block structures inclined toward the direction of the medicine cartridge 3.

[0034] By adopting the above technical solution, when the water pump 8 sucks the medicine inside the cartridge 3 through the medicine delivery tube 7, the structure of the diverting block 31 has a large resistance to the medicine flowing toward the water pump 8. When the flow rate of the medicine reaches a certain level, it will impact the diverting block 31 to drive the rotating rod 29 to rotate, and the first bevel gear 32 will rotate synchronously therewith, and continue to drive the meshing second bevel gear 33 to rotate, and the second threaded rod 28 will rotate synchronously, and the filter element 26 with its outer thread connection will move toward the direction of the cartridge 3, so that the medicine powder that has not been filtered by the filter element 26 and adheres to its surface will be pushed back into the cartridge 3, and due to the centrifugal force generated by the operation of the stirring mechanism, the medicine powder on the filter element 26 will be driven into the medicine solution for re-dissolution to avoid waste.

[0035] In addition, a torsion spring 30 is fixedly connected between the outer walls of both ends of the medicine delivery tube 7 and the rotating rod 29. When the water flow inside the medicine delivery tube 7 slows down, the rotating rod 29 can be driven to rotate and reset under the elastic action of the torsion spring 30, and then the filter element 26 can be driven to move and reset through linkage.

[0036] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
