[0031] See also Figure 5 and Figure 6 As shown, the switching assembly includes an L-shaped tube 17, a hollow ball 171, a servo motor 172 and a ball valve 173. The L-shaped tube 17 is connected to the middle of the tops of the three liquid-filling cylinders 3. The hollow ball 171 is fixedly connected between the tail ends of the three L-shaped tubes 17. The middle of the top of the hollow ball 171 is connected to the water inlet end of the water pump 5. The inside of the hollow ball 171 is rotatably connected to the ball valve 173.

A servo motor 172 is installed on the upper part of the support frame 4, and the output shaft end of the servo motor 172 is fixedly connected to the bottom end of the ball valve 173.

[0032] See also Figure 7 As shown, the liquid guide assembly includes a sliding plate 18, an inclined plate 181, a screw 182 and a drive ring 183. The sliding plate 18 is slidably connected to the bottom of the movable seat 1, and the inclined plate 181 is fixedly connected to the bottom of the sliding plate 18. The inclined plate 181 is located below the porous nozzle 8. When the liquid medicine falls onto the inclined plate 181, the inclined plate 181 can discharge the liquid medicine into the soil. The bottom of the movable seat 1 is rotatably connected to the screw 182, and the screw 182 is threadedly connected to the middle part of the sliding plate 18. The rear end of the screw 182 is fixedly connected to the drive ring 183.

[0033] First, add an appropriate amount of clean water into the liquid-filling cylinder 3 on the front side, and then add the two required liquid medicines into the two liquid-filling cylinders 3 at the rear, respectively. Then, hold the handle 2 and push the device to move next to the flowers through the movable seat 1, and make the porous nozzle 8 correspond to the flowers. Then, start the servo motor 172 to drive the ball valve 173 to rotate. The ball valve 173 rotates 120 degrees and is not connected with the front L-shaped tube 17. The ball valve 173 rotates 120 degrees and is connected with the right L-shaped tube 17. The ball valve 173 rotates 120 degrees again and is connected with the left L-shaped tube 17. When the ball valve 173 rotates to correspond to the required liquid medicine, turn off the servo motor 172, the ball valve 173 stops rotating, twist the drive ring 183 to reverse and drive the screw rod 182 to reverse, and the screw rod 182 reverses and drives the sliding plate 18 to move forward. The sliding plate 18 moves forward and drives the inclined plate 181 to move forward. When the inclined plate 181 moves forward and approaches the soil where the flowers are planted, the driving ring 183 is stopped from twisting, the screw rod 182 stops driving the sliding plate 18 to move forward, the sliding plate 18 stops driving the inclined plate 181 to move forward, and then the water pump 5 is started. The water pump 5 draws the required liquid medicine into the water outlet pipe 6 through the L-shaped tube 17 and the ball valve 173. The liquid medicine in the water outlet pipe 6 is discharged into the porous nozzle 8. The porous nozzle 8 sprays the liquid medicine on the flowers to complete the comprehensive insect prevention treatment of the flowers. At the same time, the device is pushed to move to spray the remaining flowers. When only the stems of some flowers need to be sprayed, the driving motor 13 is started to rotate forward to drive the screw rod 12 to rotate forward. The screw rod 12 rotates forward to drive the movable plate 11 to move downward. The movable plate 11 moves downward, driving the hollow cylinder 10 to move downward. The hollow cylinder 10 moves downward and gradually covers the spray holes of the porous nozzle 8, so that the upper half of the porous nozzle 8 is covered, thereby completing the adjustment of the spraying position. At the same time, the hollow cylinder 10 moves downward and also drives the porous cylinder 14 to move downward. The porous cylinder 14 moves downward and drives the scattering wheel 15 to move downward. The hollow cylinder 10 also drives the inner spline sleeve 163 to move downward through the mounting plate 16. The inner spline sleeve 163 slides on the spline shaft 161. When the spraying range of the porous nozzle 8 is adjusted, the drive motor 13 is turned off, the screw 12 stops driving the movable plate 11 to move downward, the movable plate 11 stops driving the hollow cylinder 10 to move downward, the scattering wheel 15 and the inner spline sleeve 163 stop moving downward, and the stepping motor is started. The machine 162 drives the spline shaft 161 to rotate, the spline shaft 161 drives the inner spline sleeve 163 to rotate, the inner spline sleeve 163 rotates through the belt assembly 164 to drive the porous cylinder 14 to rotate, the porous cylinder 14 rotates to drive the scattering wheel 15 to rotate, and the flowers can continue to be sprayed with medicine. Since the hollow cylinder 10 covers the upper part of the porous nozzle 8, the liquid medicine sprayed from the porous nozzle 8 is only sprayed on the stems of the flowers, and the tender leaves and flowers of the flowers will not be sprayed with the liquid medicine, and the liquid medicine sprayed from the upper part of the porous nozzle 8 is blocked by the hollow cylinder 10, and the liquid medicine falls downward through the hollow cylinder 10, passes through the porous cylinder 14 and contacts the scattering wheel 15, and the scattering wheel 15 rotates to scatter the liquid medicine, so that the scattered liquid medicine bursts onto the flowers, and part of the undispersed liquid medicine continues to fall downward onto the inclined plate 181.The liquid medicine on the inclined plate 181 is discharged and falls into the soil where the flowers are planted, thus performing an insect-proof treatment on the roots of the flowers, so that the liquid medicine can be fully utilized and waste can be avoided. This process can be repeated to continuously spray the stems of the flowers. When another liquid medicine needs to be sprayed, first start the servo motor 172 to drive the ball valve 173 to rotate, so that the ball valve 173 is connected to the front L-shaped tube 17, start the water pump 5, so that clean water is pumped out to remove the residual liquid medicine in the ball valve 173, the outlet pipe 6 and the porous nozzle 8, which can prevent the residual liquid medicine from affecting the purity and composition of the new liquid medicine, then turn off the water pump 5, start the servo motor 172 again, so that the ball valve 173 rotates to correspond to another unused liquid medicine, and according to the above operation, the liquid medicine can be sprayed on the flowers to complete the insect-proof treatment. When the flower spraying is completed, turn off the water pump 5, the porous nozzle 8 stops spraying the liquid medicine, turn off the stepper motor 162, and the spline shaft 161 stops driving the inner spline sleeve 163 rotates, the porous cylinder 14 stops driving the scattering wheel 15 to rotate, the driving motor 13 is started to reverse and drive the screw 12 to reverse, the screw 12 reverses and drives the movable plate 11 to move upward and reset, the movable plate 11 drives the hollow cylinder 10 to move upward and reset, the hollow cylinder 10 resets and stops to cover the porous nozzle 8, the hollow cylinder 10 drives the scattering wheel 15 to move upward and reset through the porous cylinder 14, and the hollow cylinder 10 also drives the inner spline sleeve 163 to move upward and reset through the mounting plate 16, and then twist the driving ring 183 to rotate forward to drive the screw rod 182 to rotate forward, the screw rod 182 rotates forward to drive the movable plate 11 to move backward and reset, and the movable plate 11 drives the inclined plate 181 to move backward and reset and retract, so as not to affect the movement of the entire device. In this way, through the action of the hollow cylinder 10, the spraying position can be adjusted to ensure the safety of tender leaves and flowers, thereby improving the safety of flower spraying.

Baffles 192 are fixedly mounted on the rotating shafts 191 on both sides of the left and right sides. The baffles 192 are located on both sides of the porous nozzle 8. The baffles 192 can block the ejected liquid medicine. An adjustment component is arranged between the rotating shaft 191 and the vertical plate 19. When the adjustment component is in operation, the adjustment component The parts can drive the rotating shaft 191 to rotate so as to adjust the position of the baffle 192; the adjusting component includes an L-shaped seat 193, a worm 194, a worm wheel 195 and an annular frame 196. The L-shaped seat 193 is symmetrically fixed to the lower part of the front side of the vertical plate 19, and the worm 194 is rotatably connected between the lower parts of the left and right L-shaped seats 193. The threads on the left and right sides of the worm 194 are opposite. The left and right ends of the worm 194 are fixedly covered with an annular frame 196, and the bottom ends of the rotating shafts 191 on the left and right sides are fixedly covered with worm wheels 195, and the worm wheels 195 are meshed with the worm 194.

[0035] When it is necessary to spray the flowers, the annular frame 196 is twisted to drive the worm 194 to rotate forward, the worm 194 drives the worm wheel 195 to rotate forward, the worm wheel 195 drives the front and rear shafts 191 to rotate forward, the front and rear shafts 191 rotate forward to drive the front and rear baffles 192 to swing towards each other, when the baffles 192 swing to ninety degrees, the annular frame 196 is stopped from being twisted, the baffles 192 are located on both sides of the multi-hole nozzle 8, and the flowers can be sprayed. When the multi-hole nozzle 8 sprays the medicine When the liquid is sprayed, part of the liquid is sprayed on the baffle 192, and the liquid falls from the baffle 192 to the inclined plate 181, and the inclined plate 181 discharges the liquid into the soil. When the flower spraying is completed, the annular frame 196 is twisted to drive the worm 194 to reverse, the worm 194 reverses to drive the worm wheel 195 to rotate in the opposite direction, the worm wheel 195 drives the shaft 191 to rotate in the opposite direction, and the shaft 191 drives the baffles 192 on the left and right sides to swing away from each other and reset, and the twisting of the annular frame 196 is stopped. In this way, it can prevent part of the liquid sprayed from the porous nozzle 8 from being wasted due to incomplete utilization, thereby improving the utilization effect of the liquid.

[0036] See also Fig. 9 As shown, the insect-proof spraying device for flower planting also includes a fixed plate 20, an n-shaped rod 21 and a wipe plate 22. The tops of the left and right baffles 192 are fixedly connected to the fixed plates 20, and the left and right fixed plates 20 are connected with n-shaped rods 21 through damping sliding. The bottom end of the n-shaped rod 21 is fixedly connected to the wipe plate 22, and the wipe plate 22 is in contact with the front side of the baffle 192. When the wipe plate 22 moves up and down, the wipe plate 22 can wipe off the residual liquid medicine on the front side of the baffle 192.

[0037] See also Fig.10 As shown, the insect-proof spray device for flower planting also includes an annular brush 23. The annular brush 23 is fixedly connected to the lower part of the inner side surface of the porous tube 14 along the circumferential direction. The annular brush 23 contacts the outer wall of the porous nozzle 8. When the annular brush 23 moves, the annular brush 23 can remove impurities on the outer wall of the porous nozzle 8.

[0038] When all the flowers are sprayed, the n-shaped rod 21 is pushed downward, and the n-shaped rod 21 drives the wiping plate 22 to move downward. The wiping plate 22 moves downward to wipe the residual liquid medicine on the baffle 192. When the wiping plate 22 moves downward to the maximum stroke, the n-shaped rod 21 is pulled to drive the wiping plate 22 to move upward to reset. In this way, the residual liquid medicine on the baffle 192 can be prevented from being corroded and affecting the subsequent use, thereby ensuring the normal use of the baffle 192.

[0039] When the porous cylinder 14 drives the scattering wheel 15 to move up and down, the porous cylinder 14 drives the annular brush 23 to move up and down, and the annular brush 23 moves up and down to remove the impurities attached to the porous nozzle 8. When the porous cylinder 14 stops moving, the porous cylinder 14 stops driving the annular brush 23 to move up and down. In this way, the impurities attached to the porous nozzle 8 can be prevented from causing blockage and affecting the spraying of the liquid medicine, thereby ensuring the normal use of the porous nozzle 8.
