[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figure 1 As shown in the figure, an embodiment provided by the present utility model: A fruit tree pesticide spraying device includes a bottom plate 1. A water supply tank 2 filled with clean water liquid is fixedly connected to the top of the bottom plate 1. A medicine agent box 3 for preparing pesticides for fruit and vegetable spraying is fixedly connected to the top of the bottom plate 1. A high-pressure water pump 4 for pumping the water liquid inside the water supply tank 2 and delivering it through the delivery pipe 5 to the inside of the bone fixing column 6 is fixedly connected to the top of the water supply tank 2. A delivery pipe 5 is fixedly connected to the top of the high-pressure water pump 4. A flushing mechanism is provided inside the medicine agent box 3.

[0035] Refer to Figure 2, the flushing mechanism includes a fixed column 6 arranged vertically. The fixed column 6 is fixedly installed on the inner wall of the medicine tank 3. The central axis of the fixed column 6 coincides with the central axis of the medicine tank 3. The top of the fixed column 6 is fixedly connected to one end of the conveying pipe 5 away from the high-pressure water pump 4. A filtering mechanism is arranged in the middle of the conveying pipe 5. The circumferential surface of the fixed column 6 is rotatably connected to a runner 7. The runner 7 is connected to the fixed column 6 through a sealed bearing to ensure the sealing performance when the runner 7 rotates, so that no liquid leaks when the runner 7 rotates around the central axis of the fixed column 6. A liquid rod 8 arranged in a hollow long rod shape is fixedly connected to the circumferential surface of the runner 7. The number of liquid rods 8 can be set as needed. One end of the liquid rod 8 away from the runner 7 is fixedly connected to a spray pipe 9. A pressurizing mechanism is arranged inside the spray pipe 9. A spraying mechanism is arranged on the top of the bottom plate 1. A protective plate 17 for protecting the internal structure of the device is fixedly connected to the top of the bottom plate 1 to prevent the branches of the fruit tree from damaging the device during movement. A push handle 18 for facilitating the pushing by the staff is fixedly connected to the right side of the protective plate 17. A roller 19 for facilitating the overall movement of the device is fixedly connected to the bottom of the bottom plate 1.

[0036] Refer to Figure 1 - Figure 4 , a liquid adding tank 10 for adding liquid into the water supply tank 2 is fixedly connected to the top of the water supply tank 2. A medicine adding tank 11 for putting medicine into the medicine tank 3 is fixedly connected to the top of the medicine tank 3. A liquid discharge pipe 12 for discharging the internal waste liquid is fixedly connected to the front of the medicine tank 3. The inside of the conveying pipe 5 is communicated with the inside of the fixed column 6. The inside of the fixed column 6 is communicated with the inside of the liquid rod 8 through the runner 7. The number of liquid rods 8 is set to be multiple. The multiple liquid rods 8 are arranged at equal angular intervals in a ring on the circumferential surface of the runner 7. The spray pipe 9 is installed at one end of the liquid rod 8 away from the runner 7 and arranged in the same rotation direction. The pressurizing mechanism includes a concentrating plate 91 for accelerating and pressurizing the liquid. The concentrating plate 91 is fixedly installed on the inner wall of the spray pipe 9. A plurality of extrusion holes 92 are formed inside the concentrating plate 91. The number of extrusion holes 92 is set to be multiple. The multiple extrusion holes 92 are arranged at equal intervals in a ring on the surface of the concentrating plate 91. The shape of the extrusion hole 92 is set to be conical. When the liquid passes through the spray pipe 9, by setting the inner wall shape of the extrusion hole 92 to be conical, the cross-sectional area of the water flow passing through gradually decreases. Thus, after the liquid passes through the extrusion hole 92, the speed and pressure of the water flow are increased, further increasing the kinetic energy when the water flow rushes out of the spray pipe 9, thereby improving the cleaning effect on the inner wall of the medicine tank 3. The liquid rod 8 and the spray pipe 9 are perpendicular to each other, and the installation directions of the spray pipes 9 on the liquid rod 8 are the same. When the liquid is sprayed out through the spray pipe 9, a reaction force will be applied to the spray pipe 9. The reaction forces superimposed by the multiple spray pipes 9 cause the liquid rod 8 and the runner 7 to rotate.

[0037] Refer to Figure 5 , Figure 6, the spraying mechanism includes a water pump 13 and a vertical column 14. The water pump 13 is fixedly installed on the top of the bottom plate 1. The water pump 13 is connected to the medicine tank 3. The water pump 13 extracts and transports the liquid medicine inside the medicine tank 3 to the inside of the vertical column 14. The vertical column 14 is threadedly installed on the top of the water pump 13. By rotating the vertical column 14, the spraying mechanism can be detached from the top of the water pump 13, which is convenient for replacing the spraying mechanism with a suitable height according to the actual height of the fruit tree, and has good adaptability. Cross bars 15 are fixedly connected to the front and rear sides of the vertical column 14. Nozzles 16 are threadedly connected to the ends of the cross bars 15 far away from the vertical column 14. Pesticides are sprayed on the fruit trees on both sides through the nozzles 16 to improve the spraying efficiency. The inside of the vertical column 14 is communicated with the inside of the cross bar 15, and the inside of the cross bar 15 is communicated with the inside of the nozzle 16.

[0038] Refer to Figure 7 , Figure 8 , the filtering mechanism includes a housing 20 and a pull rod 21. A pull ring is arranged on the front surface of the pull rod 21, which is convenient for the staff to pull forward, saving effort. The housing 20 is fixedly installed on the inner wall of the conveying pipe 5. A wedge block 22 is fixedly connected to the left side of the pull rod 21. An inclined surface is arranged on the rear side of the wedge block 22. The pull rod 21 is slidably installed on the inner wall of the housing 20. The wedge block 22 is elastically connected to the inner wall of the housing 20 through a spring 23. By setting the spring 23, a backward elastic force is applied to the wedge block 22. The filtering mechanism also includes a filter plate 24, which is used to filter the water liquid inside the water supply tank 2, improve the purification degree of the water liquid, avoid the solid substances in the water liquid remaining in the medicine tank 3 during the flushing process, and improve the flushing effect. The filter plate 24 is slidably installed on the inner wall of the housing 20. A handle 25 for conveniently pulling the filter plate 24 is fixedly connected to the top of the filter plate 24. A control groove 26 matching the wedge block 22 is opened on the right side of the filter plate 24.

[0039] Working principle: When in use, check whether each module of the device is normal, then replace the spraying mechanism with a suitable height according to the height of the fruit tree, start the water pump 13 so that the liquid medicine inside the medicine tank 3 is sprayed from the nozzle 16 onto the fruit and vegetable branches and leaves, and the staff push the device as a whole by the push handle 18 to improve the spraying uniformity.

[0040] When the device is no longer in use and the medicine tank 3 needs to be cleaned, the power supply of the high-pressure water pump 4 is started. The high-pressure water pump 4 operates to pump the water liquid inside the water supply tank 2 and successively passes through the delivery pipe 5, the fixed column 6, the rotating wheel 7, the liquid rod 8 and then sprays out from the spray pipe 9. The water liquid sprayed out from the spray pipe 9 is sprayed on the inner wall of the medicine tank 3 to clean the residual pesticides inside the medicine tank 3. At the same time, when the spray pipe 9 sprays out the water liquid, the spray pipe 9 receives a reaction force in the direction opposite to the movement direction of the water liquid, which causes the liquid rod 8 to rotate, so that the spraying direction of the spray pipe 9 is continuously changed, which can increase the cleaning range inside the medicine tank 3 and improve the cleaning effect of pesticide residues, avoiding adverse effects on the quality of drug preparation during the next use.

[0041] When the filter plate 24 needs to be replaced after long-term use, the pull rod 21 is pulled forward, driving the wedge block 22 to move forward against the elastic force of the spring 23 until the wedge block 22 disengages from the inside of the control groove 26. At this time, the wedge block 22 releases the limiting effect on the filter plate 24, and then the handle 25 is pulled upward to drive the filter plate 24 to move upward, so that the filter plate 24 can be conveniently pulled out to the outside of the housing 20 for cleaning, ensuring the filtering effect.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
