[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. For the plant growth regulator spraying device for lawn seasonal change, during the mixing operation, the raw materials and water enter the storage tank in proportion from the liquid inlet hopper. After the third servo motor is started, the second rotating rod is driven through gear transmission. On the one hand, the second rotating rod makes the movable blade rotate and stir. At the same time, with the cooperation of the reciprocating lead screw and the moving ring, the inclination angle of the movable blade can be adjusted to achieve full stirring of different liquid levels. On the other hand, the spiral rod and the mounting rod rotate with the reciprocating lead screw. The stirring blade on the mounting rod stirs the bottom liquid, and the spiral rod lifts the deposited raw materials, effectively avoiding the phenomenon of uneven mixing caused by the deposition of raw materials at the bottom, greatly improving the mixing uniformity of the plant growth regulator, ensuring the stable product quality, and providing strong support for the efficient production of the plant growth regulator.

[0019] 2. The plant growth regulator spraying device for lawn seasonal change has a flexible moving method. It can be pushed by hand using the push handle, or the tractor can be connected to the towing ring to drive the bottom plate to move, adapting to different working scenarios. When moving, the extraction pump extracts the regulator from the storage tank through the extraction pipe, and sends it to the distribution box through the delivery pipe, tee joint, and shunt hose. The lawn is sprayed by the spray head. During the spraying process, the first servo motor drives the first rotating rod and the first gear to rotate, driving the second gear meshing with it to rotate synchronously. The two first fixing rods move in a circular motion around the center of the gear. Since the first fixing rod is movably connected to the through groove formed on the surface of the movable plate, and the movable plate is movably connected to the fixed rotating shaft, one end of the movable plate moves cyclically, and the other end drives the connecting plate and the distribution box to move synchronously. This design greatly expands the spraying range of the plant growth regulator, improves the operation efficiency and coverage uniformity, and meets the spraying requirements of large-area lawns.

[0020] 3. For the plant growth regulator spraying device for lawn seasonal change, when the distribution box or the spray head is blocked or damaged, the device has a convenient replacement mechanism. The operator only needs to press the two clamping blocks into the inner cavity, and then can easily pull out the installation block from the installation box. Then, remove the quick-release joint at one end of the shunt hose, and the replacement operation of the distribution box can be carried out. The replacement process is simple and efficient. When the installation block at the lower end of the new distribution box is inserted into the installation box, due to the inclined surface design at the lower end of the clamping block, it contacts the inner surface of the installation box and then retracts into the inner cavity and compresses the spring. When the installation block is completely inserted, the spring elasticity pushes the limiting plate and the clamping block to move, and the clamping block pops out from the clamping groove and is firmly clamped, quickly completing the replacement of the distribution box. Then, connect the quick-release joint to continue the spraying operation, greatly reducing the time cost of equipment maintenance and component replacement, and improving the overall operation efficiency.

[0021] 4. The plant growth regulator spraying device for lawn seasonal change can achieve highly flexible adjustment during lawn spraying. When the second servo motor is started, the first lead screw rotates, and through the first connecting cylinder, the second lead screw and the third gear rotate synchronously. The transmission belt drives components such as the fourth gear and the third lead screw to operate in coordination. The synchronous rotation of multiple lead screws causes the two sets of moving blocks to move towards the center, driving the fixed seat to move, the movable strut to fold, and the connecting seat to move upward, thereby adjusting the height of the lifting plate and the spraying structure. This design can conveniently adjust the spraying height according to different lawn varieties, allowing the growth regulator to be sprayed at an appropriate pressure and height. In this way, the growth regulator can better penetrate into the deep soil layer, meet the needs of the lawn for the growth regulator, effectively promote the growth and development of the lawn. This device greatly improves the accuracy and effectiveness of lawn maintenance, can be flexibly operated according to the actual situation, and provides a strong guarantee for the healthy growth of the lawn.

The mounting rod 70 is welded to the lower end of the spiral rod 69. The stirring blade 71 is welded to the outer surface of the mounting rod 70.

[0034] During the mixing operation, the raw materials and water enter the storage tank 2 from the liquid inlet hopper 53 in proportion. After the third servo motor 55 is started, the second rotating rod 58 is driven through gear transmission. The second rotating rod 58 rotates and stirs the movable blade 60. At the same time, with the cooperation of the reciprocating screw rod 63 and the moving ring 64, the inclination angle of the movable blade 60 can be adjusted to achieve full stirring of different liquid levels. At the same time, the spiral rod 69 and the mounting rod 70 rotate with the reciprocating screw rod 63. The stirring blade 71 on the mounting rod 70 can stir the bottom liquid, and the spiral rod 69 can lift the deposited raw materials, effectively avoiding the phenomenon of uneven mixing caused by the deposition of raw materials at the bottom.

The fixed rotating shaft 13 is detachably connected to the upper end of the lifting plate 7. The movable plate 14 is movably connected to the outer surface of the fixed rotating shaft 13. The first fixing rod 12 is arranged in the through groove 15 and is movably connected within the through groove 15. The connecting plate 16 is welded to one end of the movable plate 14. The shunt box 26 is welded to the upper end of the mounting block 19. The nozzle 27 is detachably installed on one side of the shunt box 26. The extraction pump 3 is detachably connected to the upper end of the bottom plate 1. The extraction pipe 4 is detachably connected to one side of the extraction pump 3. The other end of the extraction pipe 4 is communicated with the storage tank 2. The delivery pipe 5 is detachably connected to the upper end of the extraction pump 3. The first pipe clamp 28 is detachably connected to one side of the lifting plate 7. The three-way joint 30 is inserted into the first pipe clamp 28. The other end of the delivery pipe 5 is detachably connected to the three-way joint 30. Two shunt hoses 31 are respectively detachably connected to both ends of the three-way joint 30. The other end of the shunt hose 31 is detachably connected to the shunt box 26 through the quick-release joint 32.

[0036] Pushing the hand push handle 72 or connecting the tractor to the towing ring 73 can drive the bottom plate 1 to move to adapt to different working scenarios. During the movement, the extraction pump 3 extracts the regulator in the storage tank 2 through the extraction pipe 4 and sends it to the shunt box 26 through the delivery pipe 5, the three-way joint 30, and the shunt hose 31. The lawn is sprayed by the nozzle 27. During the spraying process, the first servo motor 8 drives the first rotating rod 9 and the first gear 10 to rotate, driving the meshing second gear 11 to rotate synchronously. The two first fixing rods 12 make circular motions around the center of the gear. Since the first fixing rod 12 is movably connected to the through groove 15 formed on the surface of the movable plate 14, and the movable plate 14 is movably connected to the fixed rotating shaft 13, one end of the movable plate 14 moves cyclically, and the other end drives the connecting plate 16 and the shunt box 26 to move synchronously, further increasing the spraying range of the growth agent.

[0037] Example three, as Figures 4 - 6 As shown in the figure, a spraying device for plant growth regulators for lawn seasonal change. The installation box 17 is welded to the upper end of the connecting plate 16. The mounting block 19 is inserted into the installation box 17. The fixed ring 21 is welded inside the inner cavity 20.

[0038] When the diverter box 26 and the nozzle 27 are blocked or damaged, the operator only needs to press the two clamping blocks 25 into the inner cavity 20 to easily pull the mounting block 19 out of the mounting box 17, and then remove the quick-release connector 32 at one end of the diverter hose 31 to replace the diverter box 26. The replacement process is simple and efficient. When the mounting block 19 at the lower end of the new diverter box 26 is inserted into the mounting box 17, the inclined surface design of the lower end of the clamping block 25 is used to make it contact with the inner surface of the mounting box 17 and then retract into the inner cavity 20 and compress the spring 23. When the mounting block 19 is fully inserted, the elastic force of the spring 23 pushes the limit plate 24 and the clamping block 25 to move, and the clamping block 25 pops out from the clamping groove 18 and is firmly fixed, so that the replacement of the diverter box 26 is quickly completed. After that, the quick-release connector 32 is connected to continue the spraying operation.

[0039] Embodiment 4, as Figures 1 - 4 As shown, a plant growth regulator spraying device for lawn seasonal change, the second servo motor 33 is detachably connected to the front end of the first fixed plate 6, the output end of the second servo motor 33 is provided with a coupling, the output end of the second servo motor 33 is detachably connected to the first screw rod 34 through the provided coupling, the first connecting tube 35 is welded between the first screw rod 34 and the second screw rod 36, the third gear 37 is welded on the outer surface of the second screw rod 36, the fourth gear 39 is connected to the third gear 37 through a transmission toothed belt 38, the fourth gear 39 is welded on the outer surface of the third screw rod 40, the second connecting tube 41 is welded between the third screw rod 40 and the fourth screw rod 42, the first screw rod 34 and the second screw rod 36 have opposite thread directions, and the third screw rod 40 is connected to the The fourth screw rod 42 has opposite thread directions, and multiple moving blocks 43 are respectively threadedly connected to the outer surfaces of the first screw rod 34, the second screw rod 36, the third screw rod 40 and the fourth screw rod 42, the fixed seat 44 is welded to the upper end of the moving block 43, the movable strut 45 is detachably connected to the two moving blocks 43 through the first connecting shaft 47, the upper end of the movable strut 45 is detachably connected to the two connecting seats 46 through the first connecting shaft 47, the connecting block 48 is welded to the upper end of the connecting seat 46, the second fixed plate 49 is welded to the lower end of the lifting plate 7, the second fixed rod 50 is welded to the two second fixed plates 49, the connecting block 48 is slidably connected to the outer surface of the second fixed rod 50, and the second telescopic rod 51 is detachably connected between the first fixed plate 6 and the lifting plate 7.

[0040] Start the second servo motor 33 to drive the first screw rod 34 to rotate, and the second screw rod 36 and the third gear 37 are rotated synchronously through the first connecting tube 35. The transmission belt 38 drives the fourth gear 39, the third screw rod 40 and other components to operate cooperatively. The synchronous rotation of multiple screw rods causes the two groups of moving blocks 43 to move toward the center, driving the fixed seat 44 to move, the movable support rod 45 to fold, and the connecting seat 46 to move up, thereby adjusting the height of the lifting plate 7 and the spray structure.

[0041] It should be noted that the present invention is a spraying device for plant growth regulators used in lawn seasonal changes. When in use, the storage battery is installed at the upper end of the bottom plate 1 and connected to multiple servo motors. Then, the raw materials of the plant growth regulator and water are added to the storage tank 2 in proportion through the liquid inlet hopper 53. At the same time, the third servo motor 55 is started to drive the fifth gear 56 to rotate. At this time, under the meshing action, the sixth gear 57 will also rotate synchronously, and drive the second rotating rod 58 to rotate. When the second rotating rod 58 rotates, it will drive a plurality of mounting seats 59 and movable blades 60 to rotate synchronously. When the movable blades 60 rotate, they can stir the plant growth regulator in the storage tank 2. At the same time, when the second rotating rod 58 rotates, it can drive the reciprocating lead screw 63 to rotate synchronously. Since the moving ring 64 is threadedly connected to the outer surface of the reciprocating lead screw 63, and the moving ring 64 is slidably connected to the outer surface of the fixed block 68 through the rectangular groove 67, when the reciprocating lead screw 63 rotates, it can drive the moving ring 64 to move up and down reciprocally stably in the storage tank 2 with the cooperation of the fixed block 68. When the moving ring 64 moves, it will drive the connecting ring 66 to move synchronously under the action of the connecting rod 65. When the connecting ring 66 moves up and down, it can adjust the inclination angle of a plurality of movable blades 60 with the cooperation of the U-shaped fixing plate 62, so that the inclination angle of the movable blades 60 is continuously adjusted during rotation, and thus the plant growth regulator at different liquid levels in the storage tank 2 can be stirred. At the same time, when the reciprocating lead screw 63 rotates, it will drive the spiral rod 69 and the mounting rod 70 to rotate synchronously. When the mounting rod 70 rotates, it can drive a plurality of stirring blades 71 to stir the plant growth regulator at the bottom of the storage tank 2. At the same time, under the spiral rotation of the spiral rod 69, the deposited growth regulator raw materials at the bottom can be lifted, effectively solving the problem of uneven mixing caused by all the raw materials depositing at the bottom.

[0042] After the plant growth regulator is formulated, the bottom plate 1 can be driven to move by pushing the push handle 72 by hand or by connecting a tractor to the towing ring 73. When driving the bottom plate 1 to move, the extraction pump 3 is started to extract the formulated plant growth regulator in the storage tank 2 through the extraction pipe 4, and then it is transported to the three-way joint 30 through the delivery pipe 5, and then shunted to two shunt hoses 31 and then transported into the shunt box 26, and finally sprayed on the lawn by a plurality of nozzles 27. During spraying, the first servo motor 8 is started to drive the first rotating rod 9 and the first gear 10 to rotate. At this time, under the meshing action, the second gear 11 will rotate synchronously. When the first gear 10 and the second gear 11 rotate synchronously, two first fixing rods 12 can be driven to make a circular motion around the centers of the first gear 10 and the second gear 11. Since the first fixing rod 12 is installed in and movably connected to the through groove 15 formed on the surface of the movable plate 14, and at the same time the movable plate 14 is movably connected to the fixed rotating shaft 13, when the first gear 10 and the second gear 11 drive the two first fixing rods 12 to rotate synchronously, one end of the movable plate 14 will be driven to make a cyclic movement. At this time, the other end of the movable plate 14 will drive the connecting plate 16 to move synchronously, so that the two shunt boxes 26 can be driven to move synchronously, which can further increase the spraying range of the plant growth regulator.

[0043] When the shunt box 26 and the nozzle 27 are blocked or damaged, only need to press the two clamping blocks 25 into the inner cavity 20 to extract the mounting block 19 from the mounting box 17, and then remove the quick-release joint 32 at one end of the shunt hose 31 to replace the shunt box 26. When replacing, insert the mounting block 19 at the lower end of the new shunt box 26 into the mounting box 17. Since the lower end of the clamping block 25 is a slope, when inserting, the clamping block 25 will retract into the inner cavity 20 after contacting the inner surface of the mounting box 17 and will compress the spring 23 at the same time. After the mounting block 19 is completely inserted into the mounting box 17, the spring 23 will push the limiting plate 24 and the clamping block 25 to move under the action of the elastic force, so that the clamping block 25 pops out of the clamping groove 18. At this time, the clamping block 25 and the clamping groove 18 will be firmly clamped, thus completing the replacement of the shunt box 26. After the installation is completed, connect the quick-release joint 32 to the shunt box 26 to continue the spraying operation.

[0044] When spraying the lawn, the second servo motor 33 is started to drive the first lead screw 34 to rotate. At this time, under the action of the first connecting cylinder 35, the second lead screw 36 and the third gear 37 will rotate synchronously. At this time, under the driving action of the transmission belt 38, the fourth gear 39 and the third lead screw 40 can be driven to rotate synchronously, and then the second connecting cylinder 41 and the fourth lead screw 42 can be driven to rotate. When the first lead screw 34, the second lead screw 36, the third lead screw 40 and the fourth lead screw 42 rotate synchronously, the two moving blocks 43 will be driven to move synchronously towards the center position, and then a plurality of fixed seats 44 can be driven to move. At this time, the two movable struts 45 will fold, and then a plurality of connecting seats 46 can be pushed to move upward. At the same time, the lifting plate 7 and the spraying structure can be pushed to adjust the height, and the spraying height can be conveniently adjusted according to the lawn variety, so that the growth regulator can be sprayed out at a suitable pressure and height, and can better penetrate into the deep soil layer, meet the needs of the lawn for the growth regulator, and promote the growth and development of the lawn.
