DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0022] As Figures 1 to 4 shown, a pesticide sprayer for rice planting comprises an unmanned aerial vehicle body 1, a plurality of spray bar supports 2 connected to the side of the unmanned aerial vehicle body 1, and a spray bar 3 connected to the bottom of the spray bar support 2. The outer side of the spray bar 3 is connected with a protective assembly. The protective assembly comprises two symmetrically arranged protective covers 4. The top of each protective cover 4 is fixedly connected with a fixed block 12. The outer end of each fixed block 12 is connected with a rotating shaft 8. The outer side of each rotating shaft 8 is connected with a driving assembly connected with the spray bar support 2. The outer side of each protective cover 4 is connected with a cleaning piece.
[0023] As Figure 1 shown, the pesticide sprayer for rice planting in the utility model is similar in structure to the existing unmanned aerial vehicle for spraying pesticides. For example, a patent with publication number CN208021758U discloses an unmanned aerial vehicle for spraying pesticides. The main improvement of the utility model is that the spray pipe is easy to protect. As Figures 1 to 4 shown, when the spray bar 3 is not in use, the driving assembly is driven to rotate the two rotating shafts 8, which drives the fixed blocks 12 to rotate, so that the two protective covers 4 rotate relative to each other. The protective covers 4 are arranged outside the spray bar 3, so that the spray bar 3 is protected inside the protective covers 4. In this way, during the takeoff, landing and ground movement of the unmanned aerial vehicle body 1, branches, stones and other debris will not damage the spray bar 3.
[0024] As Figure 3 and Figure 4 shown, the driving assembly comprises a motor 9 and two gears 10. The bottom surface of the spray bar support 2 is fixedly connected with a mounting plate 7. The outer wall of the mounting plate 7 is fixedly installed with the motor 9. The output shaft of the motor 9 penetrates the mounting plate 7 and is fixedly connected with one of the rotating shafts 8. The outer side of each rotating shaft 8 is fixedly sleeved with a gear 10. The two gears 10 are connected with each other. The other rotating shaft 8 is rotatably connected with the mounting plate 7 at one end.
[0025] Specifically, when the protective cover 4 needs to be opened, only the motor 9 needs to be started, so that the motor 9 drives one of the shafts 8 to rotate, drives the gear 10 outside the shaft 8 to rotate, the gear 10 meshes with the gear 10 outside the other shaft 8, thereby relatively rotating the other shaft 8, the shaft 8 drives the fixed block 12 to rotate, thereby driving the two protective covers 4 to rotate and open;
[0026] The motor 9 herein is a mature technology, and the motor 9 can be electrically connected with the control system of the spraying unmanned aerial vehicle body 1, so as to meet the remote control of the motor 9 by the control panel. The above are all mature technologies, and therefore will not be described in detail here.
[0027] As shown in Figure 2 , Figure 3 and Figure 4 , the cleaning member includes a spray head 5 fixedly provided on the protective cover 4, and the water outlet end of the spray head 5 is located inside the protective cover 4. The connecting end of the spray head 5 is fixedly connected with a connecting pipeline 6, and the two connecting pipelines 6 are connected with the spray rod member 3 through valves.
[0028] Specifically, after the use of the spray rod member 3 is completed, the two protective covers 4 can be closed to wrap the spray rod member 3. At this time, the medicine bucket in the spraying unmanned aerial vehicle body 1 needs to be washed, and the cleaning water during washing will be released from the spray rod member 3. At this time, the valve, such as an electromagnetic valve, on the connecting pipeline 6 can be opened, so that the connecting pipeline 6 is in communication with the pipeline of the spray rod member 3. When the spray rod member 3 discharges the cleaning water, the cleaning water will also enter the spray head 5 through the connecting pipeline 6, so that the spray head 5 sprays the cleaning water, which can clean the outside of the spray rod member 3. The liquid adhered to the outside of the spray rod member 3 due to wind speed or atomization, thereby preventing the crystallization in the pesticide from being weathered and solidified after the outside of the spray rod member 3 contacts with the air, which can reduce the service life of the spray rod member 3.
[0029] As shown in Figure 3 and Figure 4 , the bottom outer wall of one of the protective covers 4 is fixedly connected with a clamping plate 11, and the clamping plate 11 abuts against the inner wall of the other protective cover 4.
[0030] Specifically, when the two protective covers 4 are combined, the clamping plate 11 is clamped to the inner wall of the other protective cover 4. This arrangement can improve the connection stability between the two protective covers 4.
[0031] As shown in Figure 4 , the contact surfaces of the two protective covers 4 are fixedly connected with sealing gaskets 13.
[0032] Specifically, when the spray head 5 and the spray rod 3 are in the process of discharging cleaning water, at this time, the two protective covers 4 are combined, and under the action of the sealing gasket 13, the gap contacted by the two protective covers 4 is sealed, the cleaning water can be stored in the space formed by the two protective covers 4, the loss speed of the cleaning water is slowed down, the protective cover 4 can temporarily store the cleaning water, the spray rod 3 is soaked and washed, and the cleaning effect of the outer side of the spray rod 3 is further improved.
[0033] As shown in Figure 2 , Figure 3 and Figure 4 , the outer wall of the two protective covers 4 is fixedly connected with the anti-collision strips 401. The arrangement of the anti-collision strips 401 makes the outside of the protective cover 4 from hard contact to soft contact, and effectively reduces the impact force of impact.
[0034] As shown in Figure 2 , Figure 3 and Figure 4 , the outer wall of the mounting plate 7 is fixedly installed with mounting shells on both sides, and the two gears 10 and the motor 9 are located in the two mounting shells respectively. By using the mounting shells, the gear 10 and the motor 9 can be protected respectively, so as to avoid corrosion of the gear 10 and the motor 9 caused by pesticide spraying.
[0035] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
