As described in the background art, a plant protection unmanned aerial vehicle, also called an unmanned aerial vehicle, is an unmanned aerial vehicle for agricultural and forestry plant protection operation as the name implies, and the unmanned aerial vehicle generally comprises a flight platform (fixed wing, helicopter, multiaxial aircraft), a navigation flight control part and a spraying device, and realizes the spraying operation through ground remote control or navigation flight control, and can spray medicaments, seeds, powder and the like. Agricultural unmanned aerial vehicle not only is used for spraying the application of pesticides, can also spill fertile, spill kind, spill multiple work such as fodder. Among the prior art, sprinkler generally with unmanned aerial vehicle's organism or horn fixed connection, the quick detach of sprinkler is not convenient for to this kind of mode, though some sprinkler that can realize the quick detach function have appeared on the market now, but the sprinkler of quick detach has the structure complicated problem basically on the market now.

In view of the above, referring to fig. 1 to 6, the present embodiment provides a spraying device 100 and a movable platform 1000, which can effectively improve the above-mentioned technical problems, and will be described in detail below.

Referring to fig. 1, the movable platform 1000 includes a carrier 200 and a spraying device 100, and a fixing base 20 (described in detail below) of the spraying device 100 is disposed on the carrier 200.

In this embodiment, the carrier 200 is an unmanned aerial vehicle, specifically, a plant protection unmanned aerial vehicle, which is generally equipped with an agriculturally required spraying unit, a seeding unit, and the like, and can realize spraying irrigation, seeding, and the like. Of course, the carrier 200 may be equipped with a camera, a game device, and the like. Meanwhile, the carrier 200 is also not limited to an unmanned aerial vehicle, for example, the carrier 200 may be a robot, an unmanned vehicle, an unmanned ship, or the like. Specifically, the carrier 200 includes a body 210, two arms 220 disposed on the body 210, and a rotor device 230 disposed at one end of the arms 220. Sprinkler 100 sets up in the one end of horn 220 and is located rotor 230's below, and sprinkler 100 can utilize unmanned aerial vehicle's wind field to spray like this. Of course, it is not excluded that the spraying device 100 is provided on the body 210.

It should be noted that the carrier 200 may be a dual rotor drone, or in other embodiments, may be a single rotor drone or a multi-rotor drone, such as a quad-rotor drone, a hexarotor drone, an octarotor drone, and the like. In this embodiment, the carrier 200 may automatically operate according to a preset path, a flight speed, an attitude, or the like, or may be manually controlled by an operator. In other embodiments, the driver may also be carried when the design meets the requirements, and thus the relevant operations may be manually operated by the driver in the cab. Of course, the carrier 200 can also be used in other fields such as spraying of fire extinguishing liquid in forest fires, aerial photography, power inspection, environmental monitoring, forest fire prevention, disaster patrol and the like. Alternatively, a game device or the like is mounted for interaction.

Referring to fig. 2-4, the spraying device 100 includes a spray rod 10, a fixing base 20 and a knob 30, wherein the fixing base 20 is provided with a mounting hole 201; one end of knob 30 is used to axially pass through mounting hole 201 to screw into engagement with spray bar 10, thereby locking spray bar 10 to mounting block 20, or to screw out to unlock spray bar 10 from mounting block 20. The quick release of the sprinkler 100 can be realized by the knob 30, and the overall structure is effectively simplified. In conjunction with the above, the holder 20 is mounted to the arm 220 of the carrier 200.

It should be noted that, compared with the prior art in which a complex structure is adopted to connect the fixing base 20 and the spray rod 10, in this embodiment, the quick release of the spray rod 10 can be completed only by the knob 30, which greatly improves the mounting and dismounting efficiency. The spraying device 100 can be quickly disassembled from the three parts, and has the advantages of simple structure, simplicity and convenience in disassembly and assembly, low cost, high reliability and the like on the whole.

Meanwhile, considering that the carrier 200 may be touched by an external force during flying, or the rotor device 230 may overload the spray bar 10, in this case, the spray bar 10 may be displaced or rotated with respect to the fixed base 20, and the fixed base 20 and the spray bar 10 may be worn after the phenomenon occurs, thereby greatly affecting the service life. In order to avoid the occurrence of a false position caused by displacement or rotation of the spray rod 10, in the present embodiment, the spray rod 10 is provided with the first positioning portion 101, the fixed seat 20 is provided with the second positioning portion 202, and the second positioning portion 202 and the first positioning portion 101 are guided to be in insertion fit. In the process of installing the spray rod 10 on the fixed seat 20, the first positioning portion 101 and the second positioning portion 202 can play a role in guiding installation, and after the spray rod 10 and the fixed seat 20 are assembled in place, due to the fact that the first positioning portion 101 and the second positioning portion 202 are in plug-in fit, the spray rod 10 and the fixed seat 20 are integrally stable and reliable relatively to each other due to meshing.

With reference to fig. 3 and 4, in the present embodiment, the first positioning portion 101 is a tapered guide hole, and the second positioning portion 202 is a tapered guide post. Through the conical design, the assembly guide function is achieved, and an oblique upward resultant force can be generated when the spray rod 10 is pulled, so that the unloading function is achieved. For example, during normal use, knob 30 is screwed into place, and spray bar 10 is locked against displacement and rotation. When it is desired to fold spray bar 10, knob 30 may be slightly rotated so that spray bar 10 remains connected to knob 30 but may be displaced axially, and spray bar 10 may be pulled outwardly to fold spray bar 10 by rotating spray bar 10 about the axial direction of knob 30 with first detent 101 and second detent 202 disengaged. In the process of separating the first positioning portion 101 and the second positioning portion 202, because the mating surfaces of the two are conical surfaces, a resultant force in an oblique direction can be generated, so that the spray rod 10 can be pulled to rotate, and folding and storage can be realized.

Of course, it is not excluded that in some embodiments, the first positioning portion 101 is a tapered guide post, and the second positioning portion 202 is a tapered guide hole. Alternatively, spray bar 10 is provided with both a conical guide post and a conical guide hole, and fixing base 20 is provided with both a conical guide post and a conical guide hole.

With reference to fig. 3 and 4, in the present embodiment, the number of the first positioning portions 101 is plural, the plural first positioning portions 101 are distributed around the axial screwing direction of the knob 30, and the number of the second positioning portions 202 is less than or equal to the number of the first positioning portions 101. When the number of the first positioning portions 101 and the second positioning portions 202 is the same, the first positioning portions 101 and the second positioning portions 202 can correspond to each other one to one after assembly. When the number of the second positioning portions 202 is less than the number of the first positioning portions 101, for example, in the present embodiment, the number of the first positioning portions 101 is three, for example, a, B, and C are numbered sequentially, and the number of the second positioning portions 202 is two, for example, a and B are numbered sequentially, when a and a are in plug-in fit, B is in plug-in fit with B, the spray bar 10 is at the first position relative to the fixed seat 20, and when B is in plug-in fit with a, C is in plug-in fit with B, the spray bar 10 is at the second position relative to the fixed seat 20, and therefore, in this way, the two second positioning portions 202 can be engaged with two of the first positioning portions 101, so as to adjust the angle of the spray bar 10 relative to the fixed seat 20.

Of course, it is not excluded that in some embodiments, the number of the second positioning portions 202 is multiple, the multiple second positioning portions 202 are distributed around the axial screwing direction of the knob 30, and the number of the first positioning portions 101 is less than or equal to the number of the second positioning portions 202. A similar effect can be achieved in this manner as well.

Those skilled in the art will appreciate that the number of the first positioning portions 101 may be one, two, three, four, five or more. Similarly, the number of the second positioning portions 202 may also be one, two, three, four, five, or more. Generally speaking, when the number is larger, the number can be more, which is more beneficial to fine adjustment of the angle of the spray rod 10 and increases the adjustment possibility.

Referring to fig. 3 and 4, the knob 30 provided in the present embodiment will be described in detail.

Specifically, the knob 30 includes a rotating portion 31 and a locking post 32, the locking post 32 is connected to the rotating portion 31, and an end of the locking post 32 far from the rotating portion 31 is used to axially penetrate through the mounting hole 201 to be screwed into the spray bar 10, so that the rotating portion 31 is tightly attached to a side of the fixing base 20 far from the spray bar 10. Locking post 32 may be a threaded post that threadably engages spray bar 10 to provide axial in-and out-rotation.

In addition, in order to prevent the knob 30 from being separated from the fixing base 20, in this embodiment, the knob 30 further includes a separation preventing member 33, one end of the separation preventing member 33 is connected to the rotating portion 31, and the other end of the separation preventing member 33 is used for being elastically deformed in the process of passing through the installation hole 201 and being restored to be reversed on the periphery of the installation hole 201 after passing through the installation hole 201. In the process that the locking column 32 is inserted into the mounting hole 201, the anti-falling part 33 is also inserted, when the locking column contacts the mounting hole 201, the anti-falling part 33 is pressed to deform inwards, after the end part of the anti-falling part 33 passes through the mounting hole 201, the mounting hole 201 is reversed under the reset effect, and therefore the anti-falling is achieved, and specifically, the end part of the anti-falling part 33 is provided with a barb structure. The anti-slip member 33 is a sheet structure, which may be a hard plastic structure or a metal structure.

When the anti-slip member 33 of the knob 30 is mounted in the mounting hole 201, the knob 30 is not disengaged with respect to the holder 20 while allowing the knob 30 to rotate with a small force applied.

Of course, in order to better achieve the anti-slip effect, in this embodiment, the number of the anti-slip parts 33 is multiple, and the multiple anti-slip parts 33 are distributed around the circumferential direction of the locking column 32 at intervals. Specifically, the number of the anti-slip members 33 is four, and four are evenly distributed around the circumferential direction of the locking column 32. Of course, it is not excluded that in some embodiments the anti-slip means 33 is a structure, for example a ring-shaped structure, which is arranged around the locking post 32.

In order to enhance the locking effect, reduce the cost and improve the hand feeling, in this embodiment, the locking column 32 is a metal piece, the rotating portion 31 is a plastic piece, and the locking column 32 and the rotating portion 31 are integrally formed. In this embodiment, one end of the locking post 32 is embedded in the rotation part 31 and is integrally formed during manufacturing. Thus, the rotating portion 31 is easy for the operator to rotate, and the locking post 32 has strong rigidity and strength to maintain the fixing effect of the spray rod 10.

Referring to fig. 3-6, the fixing base 20 provided in the present embodiment will be described in detail.

In this embodiment, the fixing base 20 includes an outer ring structure 21, a circular truncated cone structure 22, and an inner ring structure 23; the inner ring structure 23 is positioned in the outer ring structure 21, the outer edge of the inner ring structure 23 is connected with the inner edge of the circular truncated cone structure 22, and the outer edge of the circular truncated cone structure 22 is connected with the periphery of one side, far away from the spray rod 10, of the outer ring structure 21; the mounting hole 201 is located at the middle position of the inner ring structure 23; the second locating portion 202 is located on the inner ring structure 23 and/or the boss structure 22. Specifically, the second positioning portion 202 extends over the inner ring structure 23 and the circular truncated cone structure 22, which facilitates overall structural uniformity.

Meanwhile, a first receiving groove 26 is defined between the side of the circular truncated cone structure 22 away from the spray rod 10 and the inner ring structure 23 to receive part of the structure of the knob 30. With reference to fig. 5 and 6, the fixing base 20 is designed such that a first receiving groove 26 is formed at a side of the fixing base 20 close to the rotating part 31, thereby facilitating to receive a part or all of the rotating part 31.

Generally, the thickness of the structure of the fixing base 20 can be designed to be slightly thinner, so as to achieve the overall light weight, in order to strengthen the structure of the fixing base 20, in the present embodiment, the second positioning portion 202 is a cylindrical structure protruding toward the spray rod 10, and a reinforcing rib 24 is disposed between the second positioning portion 202 and the inner wall of the outer ring structure 21. This body structure may be understood as the tapered guide post mentioned above.

Of course, to facilitate capping the end of spray bar 10, in this embodiment, a second receiving slot 27 is defined between the side of outer ring structure 21 adjacent spray bar 10 and inner ring structure 23 and circular truncated cone structure 22 to receive an end of spray bar 10.
