Detailed Description
Embodiment one:
referring to fig. 1 to 2, an embodiment of the present invention provides an unmanned aerial vehicle assembly, which is mainly used for improving a spraying range and an effect of the assembly after being applied to an unmanned aerial vehicle body 8, the assembly includes a base 1 detachably connected with the bottom of the unmanned aerial vehicle body 8, a medicine hopper 2 for containing medicine liquid is rotatably mounted at the bottom of the base 1, and a discharging assembly 4 for spraying the medicine liquid is disposed on the medicine hopper 2, and in order to ensure a spraying effect in this embodiment, the number of the discharging assemblies 4 is three and are distributed in an annular array along the hopper.
Further, a control component 3 which is used for driving the medicine hopper 2 to rotate and is in transmission connection with the three discharging components 4 is arranged in the base 1; when the control component 3 is started, the medicine hopper 2 and the discharging component 4 can be driven to synchronously rotate along the bottom of the base 1, and the discharging component 4 can be driven to automatically rotate based on the medicine hopper 2.
Referring to fig. 1 to 5, in the present embodiment, it is preferable that: the control assembly 3 comprises a housing 301 and a motor 302 which are fixedly connected with the bottom of the base 1, the motor 302 is positioned in the housing 301, a connecting rod 303 which is fixedly connected with the medicine hopper 2 is fixedly arranged on an output shaft of the motor 302, and when the motor 302 is started, the medicine hopper 2 can be driven to synchronously rotate through the connecting rod 303. The bottom of the housing 301 is fixedly provided with a main conical fluted disc 304 movably sleeved outside the connecting rod 303, and an auxiliary conical fluted disc 305 assembled with the discharging component 4 in a key shaft type is connected on the main conical fluted disc 304 in a transmission way; the main conical fluted disc 304 does not rotate synchronously with the connecting rod 303, and when the medicine hopper 2 drives the discharging component 4 and the auxiliary conical fluted disc 305 to rotate, the auxiliary conical fluted disc 305 moves around the main conical fluted disc 304 to automatically rotate, so that the discharging component 4 also rotates.
The outer surface of the housing 301 is fixedly provided with a wedge-shaped ring 306 movably attached to the discharging component 4, when the discharging component 4 rotates along with the medicine hopper 2, the end part of the discharging component 4 positioned in the medicine hopper 2 moves along the wedge-shaped ring 306, and the discharging component 4 moves up and down based on the auxiliary conical fluted disc 305, so that the auxiliary conical fluted disc 305 is assembled with the key shaft of the discharging component 4. Specifically, wedge ring 306 is generally petaloid-shaped having a relatively protruding land based on the outer surface of housing 301, and is configured to descend based on secondary bevel disk 305 when tapping assembly 4 is in contact with the relatively protruding land.
In the structure, the housing 301 can be matched with the main conical fluted disc 304 to form a complete seal with the motor 302, so that the subsequent wet corrosion caused by the contact between the liquid medicine entering the housing 301 and the motor 302 is avoided, and the liquid medicine in the medicine hopper 2 can be completely discharged for effective utilization. Meanwhile, the medicine hopper 2 is provided with an inclined table surface, the discharging components 4 are arranged on the inclined table surface, and the medicine hopper 2 is also provided with a charging hole (not shown in the figure), so that quick replenishment of medicine liquid can be realized in the later stage.
Further, the discharging component 4 comprises a guide pipe 401 assembled with the auxiliary bevel disk 305 in a key shaft mode, the lower end of the guide pipe 401 extends out of the medicine hopper 2 and is fixedly provided with a spray head 402, the upper end of the guide pipe 401 is located in the medicine hopper 2 and is movably attached to the wedge-shaped ring 306, and when the guide pipe 401 moves along with the auxiliary bevel disk 305, the wedge-shaped ring 306 can drive the guide pipe 401 to move up and down. Wherein, the outer surface of the conduit 401 and the area positioned in the medicine hopper 2 are provided with liquid inlet holes, thereby realizing the transportation of the medicine liquid in the medicine hopper 2 to the spray head 402 through the conduit 401.
Meanwhile, in order to realize automatic resetting after the movement of the catheter 401, a spring (not shown in the figure) is fixedly mounted on the catheter 401, and the spring can be arranged in the medicine bucket 2 to abut against the inner wall of the medicine bucket 2, can also be arranged in the medicine bucket 2 to abut against the auxiliary bevel gear 305, and can also be arranged outside the medicine bucket 2 to abut against the outer surface of the medicine bucket 2. The spring does not form a connection with the hopper 2/sub-cone ring 305 and therefore does not interfere with movement.
It should be noted that, the guide tube 401 is movably installed between the medicine hopper 2, that is, the guide tube 401 can rotate automatically based on the medicine hopper 2, and the guide tube 401 can also move up and down based on the medicine hopper 2.
Further, as shown in fig. 5, the middle section of the catheter 401 may be flexible, while the two end portions are still rigid, and the bottom of the drug hopper 2 is fixedly provided with a guide rail 5 movably covered outside the catheter 401, so that the catheter 401 can move along the guide rail 5 without detachment. At this time, a corresponding bending may occur in the guide rail 5 when the guide pipe 401 descends, so that the spray head 402 may be relatively far from the medicine hopper 2 in the horizontal direction.
When the unmanned aerial vehicle is used, the unmanned aerial vehicle body 8 drives the base 1 and the medicine hopper 2 to lift off and move along a designated area, meanwhile, the motor 302 is started to drive the connecting rod 303 to rotate, so that the medicine hopper 2 is driven to rotate along the base 1, the medicine hopper 2 is driven to synchronously move through the guide pipe 401, the auxiliary bevel gear disc 305 can rotate when moving along the main bevel gear disc 304, the guide pipe 401 can also rotate automatically in the process of rotating along with the medicine hopper 2, and the guide pipe 401 has the revolution and autorotation movement process at the same time; when the guide tube 401 rotates synchronously with the medicine hopper 2, the guide tube moves synchronously along the wedge-shaped ring 306, so that the spray head 402 is driven to move up and down based on the inclined table surface of the medicine hopper 2. In the above process, the liquid medicine in the medicine hopper 2 can be continuously sprayed out through the guide pipe 401 and the spray head 402, so that the spraying area of the spray head 402 on the liquid medicine can be effectively improved, and the spraying effect is more uniform.
It should be noted that, in this embodiment, the motor 302 may be a unidirectional motor that can rotate only in one direction, or a servo motor may be used to realize corresponding rotation in two different directions. Meanwhile, if the medicine hopper 2 is arranged without the inclined table surface, the whole body is cylindrical, the main bevel gear disk 304 and the auxiliary bevel gear disk 305 can be correspondingly replaced by plane gears, and the whole movement process can be realized, but the spraying range of the spray head 402 can be greatly reduced.
In summary, through the cooperation of the structures of the main bevel gear disk 304, the auxiliary bevel gear disk 305, the medicine hopper 2, the guide pipe 401 and the like, the spray head 402 can simultaneously form a revolution process, a rotation process and an up-and-down movement process, so that the spraying range of the medicine liquid can be effectively improved, and the medicine liquid can be uniformly sprayed because of the revolution and the rotation of the spray head 402. The whole structure is compact, the medicine hopper 2 is matched with the wedge ring 306, the auxiliary bevel gear disc 305 and the guide pipe 401 in the inside during rotation, and the medicine hopper 2 has the effect of continuously stirring the medicine liquid in the medicine hopper 2, so that the influence of precipitation of the medicine liquid in the medicine hopper 2 on the medicine liquid effect is avoided. The size of the medicine hopper 2 can be set larger because the threaded rod extending from the lower part of the box body in the comparison file is not required to be arranged, so that the duration of single use is prolonged; because the structure which is arranged in an exposed way relative to the medicine hopper 2 is only the guide pipe 401 and the spray head 402, contact interference during arrangement and transportation can be avoided, and the practicability is higher.
Embodiment two:
referring to fig. 1 to 6, in order to ensure that the liquid medicine in the medicine hopper 2 can be completely discharged and utilized, an improvement is made to the liquid inlet mode of the catheter 401: an output assembly 6 for conveying the liquid medicine to the guide pipes 401 is arranged in the medicine hopper 2, the output assembly 6 can directly suck the liquid medicine on the bottom surface of the medicine hopper 2, and meanwhile, the output assembly 6 can stably convey the liquid medicine to the three guide pipes 401 in an equivalent amount.
Referring to fig. 1 to 7, in the present embodiment, it is preferable that: the output assembly 6 comprises a pump body 601 fixedly arranged in the housing 301, an inlet pipe 602 extending to the bottom of the medicine hopper 2 is fixedly arranged at the inlet of the pump body 601, and the inlet pipe 602 penetrates through the main conical fluted disc 304. The outlet of the pump body 601 is connected with the connecting rod 303, at this time, a flow passage 307 is formed inside the connecting rod 303, and an outlet pipe 603 connected with the three pipes 401 is fixedly connected with the outer surface of the connecting rod 303.
In the above structure, a ring (not shown) is rotatably connected to the outer surface of the connecting rod 303 and located inside the housing 301, and the ring is connected to the outlet of the pump body 601, so that the rotation of the connecting rod 303 does not interfere with the pump body 601, and the liquid medicine can be continuously delivered into the flow channel 307 of the connecting rod 303 through the ring.
Because the inlet pipe 602 extends downwards through the main conical fluted disc 304 and the outlet pipe 603 rotates synchronously with the connecting rod 303, the lower end of the inlet pipe 602 can adopt a flexible design, so that the inlet pipe 602 can automatically bend to avoid when the outlet pipe 603 contacts with the inlet pipe 602 along with the rotation of the connecting rod 303. The bending deformation of the inlet pipe 602 can play a role in stirring the liquid medicine at the bottom of the medicine hopper 2 on one hand, and can avoid the inlet pipe 602 from being blocked on the other hand.
Since the guide tube 401 has both revolution and rotation, the outlet tube 603 is connected to the tip of the guide tube 401 by rotation, and the rotation of the guide tube 401 does not interfere with the outlet tube 603. At the same time, the outlet tube 603 also has the function of stirring the liquid medicine in the medicine hopper 2 along with the rotation of the connecting rod 303.
The pump body 601 is placed in the housing 301 and has a sealing function through the main conical fluted disc 304, namely, the liquid medicine in the medicine hopper 2 can not be contacted with the pump body 601, so that the pump has beneficial effects on the discharge utilization of the liquid medicine and the service life of the pump body 601, and the further utilization of the space in the housing 301 can be realized.
When in use, the spray head 402 has revolution process, rotation process and up-down movement process simultaneously through the structures of the main cone fluted disc 304, the guide tube 401 and the like, so that the spraying range of the liquid medicine can be effectively improved, and the working process and the effect of the part are the same as those of the first embodiment, and the repeated description is omitted. The difference is that: when the motor 302 is started, the pump body 601 also synchronously works, liquid medicine is extracted from the bottom surface of the medicine hopper 2 through the inlet pipe 602, then is conveyed to the guide pipe 401 through the flow passage 307 and the outlet pipe 603 in the connecting rod 303, and finally is sprayed through the spray head 402. When the connecting rod 303 drives the catheter 401 to rotate through the medicine hopper 2, the outlet pipes 603 can rotate synchronously with the catheter 401, and the outlet pipes 603 are correspondingly arranged along the outside of the connecting rod 303 so that the medicine throughput of the three outlet pipes 603 is consistent.
In the first embodiment, although the spraying range of the smoke liquid can be remarkably improved, the liquid medicine on the lower side of the guide tube 401 in the medicine hopper 2 cannot be completely discharged through the spray head 402, so that the liquid medicine accumulation can occur in the medicine hopper 2, the whole utilization of the liquid medicine cannot be realized, and adverse chemical reaction can be generated by mixing with different subsequent liquid medicines, so that certain use limitations exist.
Compared with the first embodiment, through the cooperation of the structures such as the outlet pipe 603, the main conical fluted disc 304, the flow passage 307, the inlet pipe 602 and the like, liquid can be directly pumped from the bottom of the medicine hopper 2 and conveyed, so that the whole discharge and utilization of the liquid medicine in the medicine hopper 2 can be realized, and the utilization rate of the liquid medicine reaches the highest; the liquid amount of each outlet pipe 603 is stabilized and equal by the liquid flowing through the flow channels 307 in the connecting rod 303 to the arranged outlet pipes 603, so that the spraying uniformity of the liquid medicine is further ensured. The whole scheme combines with the setting of connecting rod 303 and housing 301 together, and the setting of exit tube 603 and advance pipe 602 still has the effect of stirring the inboard liquid medicine of medicine fill 2, can further avoid the precipitation influence of liquid medicine, and the suitability is stronger.
Embodiment III:
referring to fig. 1 to 9, on the basis of the second embodiment, in order to ensure the use effect of the liquid medicine and the convenience of subsequent cleaning, an improvement is made to the internal structure of the medicine hopper 2: the laminating component 7 movably laminated with the inner wall of the medicine hopper 2 and the outer surface of the connecting rod 303 is jointly arranged between the housing 301 and the main conical fluted disc 304, the housing 301 and the main conical fluted disc 304 enable the laminating component 7 to be fixed relative to the base 1, and the laminating rotation of the laminating component 7 relative to the medicine hopper 2 can be automatically realized by utilizing the rotation of the medicine hopper 2 based on the base 1.
Referring to fig. 1 to 10, in the present embodiment, it is preferable that: the attaching assembly 7 comprises an upper bracket 701 fixedly connected with the housing 301 and a lower bracket 702 fixedly connected with the main conical fluted disc 304, wherein the upper bracket 701 and the lower bracket 702 are movably attached to the inner wall of the medicine hopper 2, and the lower bracket 702 and the upper bracket 701 are arranged in a staggered manner with the outlet pipe 603; adjacent sides of the upper bracket 701 and the lower bracket 702 are elastically connected with a movable propping-up top block 703 through a spring (not shown in the figure), and the upper bracket 701 and the lower bracket 702 are formed continuously through the top block 703.
Meanwhile, an avoidance section 704 is further formed between adjacent sides of the upper support 701 and the lower support 702, and the length dimension of the avoidance section 704 is larger than or equal to the diameter dimension of the catheter 401, so that when the drug hopper 2 drives the catheter 401 to move, the catheter 401 can pass through the upper support 701 and the lower support 702 through the avoidance section 704, and further contact interference is avoided.
Wherein, the opposite sides of the two top blocks 703 are provided with chamfers so that the two top blocks 703 can be pushed to separate to both sides and correspondingly compress the springs when the catheter 401 passes through the upper bracket 701 and the lower bracket 702; the chamfer can also be in the shape of the outer surface of the catheter 401, thereby improving the contact area with the inner wall of the drug hopper 2 and also having a certain scraping effect on the outer surface of the catheter 401. Meanwhile, the top block 703 is slidably arranged at the lower sides of the upper bracket 701 and the lower bracket 702, so that the bottom surface of the top block 703 can form movable fit with the inner wall of the medicine hopper 2.
When the spray head is used, the spray head 402 has the revolution process, the rotation process and the up-and-down movement process simultaneously through the structures of the main cone fluted disc 304, the guide tube 401 and the like, the spraying range of liquid medicine can be effectively improved, the liquid medicine can be completely discharged and utilized from the bottom of the medicine hopper 2 through the structures of the outlet tube 603, the inlet tube 602 and the like, and the working process and the effect of the part are the same as those of the second embodiment, and the repeated description is omitted. The difference is that: when the motor 302 is started to drive the medicine hopper 2 to rotate based on the base 1, the upper bracket 701, the lower bracket 702 and the top block 703 relatively move along the inner wall of the medicine hopper 2, at this time, the inlet pipe 602 and the lower bracket 702 are kept relatively static, and the outlet pipe 603 can normally deliver liquid into the catheter 401; in this process, the upper bracket 701, the lower bracket 702 and the top block 703 have the function of stirring all the liquid medicine in the medicine hopper 2 from top to bottom, and also have the function of scraping all the inner wall areas of the medicine hopper 2 from top to bottom, so as to thoroughly avoid accumulation of the liquid medicine in the medicine hopper 2. The water is added into the medicine hopper 2 during the later cleaning to match with the comprehensive scraping effect, so that the medicine hopper 2 can be thoroughly cleaned.
In the second embodiment, although the bottom liquid extraction can be realized to improve the utilization rate of the liquid medicine, the cleaning of the post-stage medicine hopper 2 after use is troublesome, the thorough cleaning of the medicine hopper 2 cannot be realized, and adverse reactions can be generated by mixing with different subsequent liquid medicines, so that certain use limitations exist.
Compared with the second embodiment, through the cooperation of the structures such as the medicine hopper 2, the upper bracket 701, the lower bracket 702 and the top block 703, the medicine hopper 2 can move relative to the upper bracket 701, the lower bracket 702 and the top block 703 during rotation, so that continuous stirring of all medicine liquid in the medicine hopper 2 can be realized, and all areas of the inner wall of the medicine hopper 2 can be scraped, so that the follow-up thorough cleaning of the medicine hopper 2 is facilitated, and the integral normal long-term use is ensured. The whole scheme combines with the rotation of medicine fill 2 together, has reached multi-functional purpose, and because laminating subassembly 7 is motionless and medicine fill 2 rotates and motor 302 can two-way reciprocal rotation for stirring effect and later cleaning effect are better, have satisfied more demands in the in-service use.
