Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1-3, the present embodiment provides a spraying structure including a liquid storage container 1 and a rotary driving member 2. The liquid storage container 1 is provided with a first through opening, and the output shaft 20 of the rotary driving member 2 is arranged in the first through opening of the liquid storage container 1 in a penetrating manner. The spraying structure further comprises an annular first sealing element 3, the first sealing element 3 is sleeved on the output shaft 20 of the rotary driving element 2 in a sealing mode, and the first sealing element 3 is abutted and fixed to the inner side of the side wall, provided with the first through opening, of the liquid storage container 1. Or, the spraying structure further comprises an annular second sealing element 4, the second sealing element 4 is sleeved on the output shaft 20 of the rotary driving element 2 in a sealing mode, and the second sealing element 4 is abutted and fixed to the outer side of the side wall, provided with the first through hole, of the liquid storage container 1. Or, this sprinkling structure still includes annular first sealing member 3 and annular second sealing member 4, and first sealing member 3 and second sealing member 4 all seal the cover and cup joint on the output shaft 20 of rotary driving piece 2, and just first sealing member 3 butt is fixed in the inboard that is provided with the lateral wall of first opening of liquid storage container 1, and second sealing member 4 butt is fixed in the outside that is provided with the lateral wall of first opening of liquid storage container 1.
When the spraying structure further comprises the annular first sealing element 3, the first sealing element 3 is sleeved on the output shaft 20 of the rotary driving element 2 in a sealing mode, and the first sealing element 3 is fixed and abutted to the inner side of the side wall, provided with the first through opening, of the liquid storage container 1, so that the first sealing element 3 can seal a gap between the first through opening of the liquid storage container 1 and the output shaft 20 of the rotary driving element 2 in the axial direction and the radial direction of the output shaft 20 of the rotary driving element 2, the stability of the first sealing element 3 can be guaranteed, and liquid in the liquid storage container 1 can be effectively prevented from flowing into the rotary driving element 2 after passing through the gap.
When the spraying structure further comprises the annular second sealing element 4, the second sealing element 4 is sleeved on the output shaft 20 of the rotary driving element 2 in a sealing mode, and the second sealing element 4 is fixed and abutted to the outer side of the side wall, provided with the first through opening, of the liquid storage container 1, so that the second sealing element 4 can seal a gap between the first through opening of the liquid storage container 1 and the output shaft 20 of the rotary driving element 2 in the axial direction and the radial direction of the output shaft 20 of the rotary driving element 2, the stability of the second sealing element 4 can be guaranteed, and liquid in the liquid storage container 1 can be effectively prevented from flowing into the rotary driving element 2 after passing through the gap.
It should be noted that, any one of the inside and the outside of the side wall of the liquid storage container 1 provided with the first through opening abuts against and is fixed with a sealing member, so that the sealing property of the gap between the first through opening of the liquid storage container 1 and the output shaft 20 of the rotary driving member 2 can be ensured, and therefore when spraying operation is performed, liquid in the liquid storage container 1 can be effectively prevented from flowing out of the liquid storage container 1 after passing through the gap, and further, the risk that the flowing liquid flows into the inside of the rotary driving member 2 along the output shaft 20 of the rotary driving member 2 can be reduced.
Compared with the prior art, the utility model provides a spray structure and fix first sealing member 3 in the inboard that is provided with first opening of liquid storage container 1, perhaps, fix second sealing member 4 in the outside that is provided with first opening of liquid storage container 1, perhaps, fix first sealing member 3 in the inboard that is provided with first opening of liquid storage container 1 and fix second sealing member 4 in the outside that is provided with first opening of liquid storage container 1, thereby when making plant protection unmanned aerial vehicle spray the operation, the stability of first sealing member 3 or second sealing member 4 can be guaranteed, and then can effectively block the outflow of the first opening department of liquid storage container 1 of liquid in the liquid storage container 1, reduce the risk of the inside entering liquid of rotary driving piece 2.
It can be seen that the box bottom both sides of the water storage box of the plant protection unmanned aerial vehicle sprinkler that this embodiment provided have been alleviated to the structure of spraying that exists among the prior art all are provided with the sealing washer, but above-mentioned sealing washer is fixed in the pivot of rotary driving spare 2 such as motors through the mode that cup joints, and stability is relatively poor, when plant protection unmanned aerial vehicle sprays the operation, the sealing washer that is located water storage box inside can not effectively block liquid and follow the outflow of the box bottom of water storage box, leads to still having the technical problem of the risk of the inside entering liquid of rotary driving spare 2.
In practical applications, in order to prevent friction between the liquid storage container 1 and the output shaft 20 of the rotary driving member 2 and thereby influence the rotation process of the output shaft 20, a gap is usually provided between the first through opening of the liquid storage container 1 and the rotating shaft. In order to prevent the liquid from flowing into the rotary driving member 2 along the output shaft 20 after passing through the gap, a first sealing member 3 and a second sealing member 4 are respectively arranged between two sides of the side wall of the liquid storage container 1 provided with the first through opening and the output shaft 20 of the rotary driving member 2. The first sealing member 3 and the second sealing member 4 are matched to effectively prevent liquid from flowing out of the first through hole of the liquid storage container 1.
Note that either one of the first seal 3 and the second seal 4 is fixed to and in contact with a side wall of the liquid storage container 1 in which the first port is provided, and the other one is capable of rotating with the rotation of the output shaft 20 of the rotary drive member 2, and may also function to seal a gap between the first port of the liquid storage container 1 and the output shaft 20 of the rotary drive member 2.
Further, as shown in fig. 2, the spraying structure provided by this embodiment further includes a fixing member 5. The fixing member 5 is installed on the inner side wall of the liquid storage container 1 and is abutted against one side of the first sealing member 3, which is far away from the first opening of the liquid storage container 1, so that the first sealing member 3 is fixed between the fixing member 5 and the inner side wall of the liquid storage container 1.
Because the fixing part 5 installed on the inner side wall of the liquid storage container 1 is abutted to one side, far away from the first through hole of the liquid storage container 1, of the first sealing part 3, the fixing part 5 can be fixed between the fixing part 5 and the inner side wall of the liquid storage container 1 stably in the axial direction of the output shaft 20 of the rotary driving part 2, the first sealing part 3 is prevented from moving in the axial direction of the output shaft 20 of the rotary driving part 2, therefore, the first sealing part 3 can effectively play a sealing role in the axial direction and the radial direction of the output shaft 20 of the rotary driving part 2, liquid is blocked from flowing out from the first through hole of the liquid storage container 1, and the risk of liquid entering the inside of the rotary driving part 2 is reduced.
It should be noted that, since the fixing member 5 fixes the first sealing member 3 between the fixing member 5 and the inner side wall of the liquid storage container 1, when the output shaft 20 of the rotary driving member 2 rotates, relative friction is generated between the first sealing member 3 and the output shaft 20. Therefore, the first sealing member 3 can be made of wear-resistant material, and the abutting force between the fixing member 5 and the first sealing member 3 is adjusted to be smaller, so that the pressure applied to the first sealing member 3 can be reduced, and the friction force between the first sealing member 3 and the output shaft 20 can be reduced.
In practice, the rotary drive 2 may be a motor, and the output shaft 20 of the rotary drive 2 may be a rotating shaft of the motor. The liquid in the liquid container may be water or water in which a drug is dissolved.
As shown in fig. 2 and 4, the fixing member 5 is provided with a stepped hole penetrating both sides of the fixing member 5, the fixing member 5 is fitted over the output shaft 20 of the rotary driving member 2, and a gap is provided between the inner side wall of the stepped hole and the output shaft 20 of the rotary driving member 2. As shown in fig. 4, in the stepped hole, a hole with a larger hole diameter on one side of the fixing member 5 is used for forming an accommodating cavity 50 on one side of the fixing member 5, the first sealing member 3 is located in the accommodating cavity 50, and a side wall of the accommodating cavity 50 located at the step of the stepped hole abuts against one side of the first sealing member 3 away from the rotary driving member 2.
In this embodiment, the stepped hole may include two through holes having different diameters, and the two through holes are coaxially disposed and communicate to form the stepped hole.
The side of the fixing member 5 provided with the accommodating cavity 50 can abut against the inner side of the side wall of the liquid storage container 1 provided with the first through opening, the accommodating cavity 50 is covered on the side of the first sealing member 3, and the accommodating cavity 50 of the fixing member 5 can block most of liquid from contacting the first sealing member 3. The clearance between the inner side wall of the stepped bore and the output shaft 20 of the rotary drive member 2 allows the first seal member 3 to withstand a small water volume impact during the spraying operation.
It can be seen that the holding cavity 50 of the fixing member 5, and the gap between the inner side wall of the stepped hole and the output shaft 20 of the rotary driving member 2 can be mutually matched, the bearing water amount of the first sealing member 3 can be effectively reduced, and the probability that the liquid flows into the first sealing member 3 can be reduced, so that the liquid can be further effectively blocked from flowing out from the first through hole of the liquid storage container 1.
As shown in fig. 5, the side of the fixing member 5 away from the accommodating chamber 50 is provided with an extension sleeve 51, and the extension sleeve 51 is communicated with the stepped hole. The extension sleeve 51 is sleeved on the rotating shaft of the rotary driving member 2, and a gap is formed between the inner side wall of the extension sleeve 51 and the output shaft 20 of the rotary driving member 2.
The extension sleeve 51 is fixed on one side of the fixing member 5 in a sealing manner, and further, the extension sleeve 51 may be integrally formed with the fixing member 5.
The extension sleeve 51 and the gap between the inner side wall of the extension sleeve 51 and the output shaft 20 of the rotary driving member 2 can further reduce the possibility of liquid flowing into the first sealing member 3, and further effectively block the liquid from flowing out from the first through hole of the liquid storage container 1.
Wherein, for the probability that effectively reduces liquid inflow first sealing member 3 department, the clearance between the inside wall of shoulder hole and the output shaft 20 of rotary driving piece 2 to and, the clearance between the inside wall of extension cover 51 and the output shaft 20 of rotary driving piece 2 all can be millimeter level clearance.
As shown in fig. 4 and 5, the fixing member 5 is provided with an ear plate 52 on the outer peripheral wall thereof. The ear plate 52 is provided with a threaded hole 520 extending along the axial direction of the fixing member 5, and a screw is mounted at the threaded hole 520 and connected with the inner side of the side wall of the liquid storage container 1 provided with the first through hole.
The plate surface of the ear plate 52 may be on the same plane as the side surface of the fixing member 5 on which the accommodating cavity 50 is disposed. When the fixing member 5 is fixed to the inner side of the side wall of the liquid storage container 1 provided with the first through opening by a screw, the ear plate 52 and the side surface of the fixing member 5 on the side provided with the accommodating cavity 50 are both attached to the inner side of the side wall of the liquid storage container 1 provided with the first through opening. At this time, the screw fitted in the screw hole 520 of the lug plate 52 is screwed into the side wall of the liquid storage container 1 where the first through hole is provided, so that the fixing member 5 can be fitted to the inner side of the side wall of the liquid storage container 1 where the first through hole is provided, and the accommodating chamber 50 can be irradiated to the side of the first seal member 3.
As shown in fig. 4, two ear plates 52 may be provided on the fixing member 5, and the two ear plates 52 are symmetrically installed on both sides of the fixing member 5 with the central axis of the fixing member 5 as a center of symmetry.
The ear plate 52 serves to improve the mounting stability between the fixing member 5 and the side wall of the liquid storage container 1 in which the first through opening is provided.
As shown in fig. 5, the threaded hole 520 has a tapered structure from one end of the threaded hole 520 away from the receiving cavity 50 to the other end.
When the spraying structure that this embodiment provided sprays the operation, liquid storage container 1 is located the top of rotary driving piece 2, and thus the one side that is provided with holding chamber 50 of mounting 5 is located the below, and the opposite side of mounting 5 is located the top, and correspondingly, the great one end in aperture of screw hole 520 is located the top of the less one end in aperture. Therefore, compared with the case that the threaded hole 520 is the equal-diameter threaded hole 520, the threaded hole 520 is of the tapered structure, so that liquid can not easily pass through the gap between the threaded hole 520 and the screw and then reach the outer side of the liquid storage container 1, and the risk that the liquid enters the inside of the rotary driving member 2 can be further reduced.
Further, the threaded hole 520 formed in the ear plate 52 may be conical or truncated cone-shaped, so as to prevent liquid from entering a gap between the fixing member 5 and the liquid storage container 1 through the threaded hole. The shape of the threaded hole 520 can be selected according to actual requirements.
In this embodiment, the reservoir 1 is fixed relative to the rotary drive member 2. The distance between the rotary driving member 2 and the outer side of the side wall of the liquid storage container 1 provided with the first through opening is not greater than the thickness of the second sealing member 4 along the axial direction of the output shaft 20 of the rotary driving member 2.
The rotary driving member 2 includes a casing, and the relative fixation between the liquid storage container 1 and the rotary driving member 2 means the relative fixation between the liquid storage container 1 and the casing of the rotary driving member 2. The liquid storage container 1 and the housing of the rotary driving member 2 can be connected together by fasteners such as bolts.
When the distance between the rotary driving element 2 and the outer side of the side wall, provided with the first through opening, of the liquid storage container 1 is not greater than the thickness of the second sealing element 4, the side wall, provided with the first through opening, of the liquid storage container 1 and the machine shell, provided with the first through opening, of the rotary driving element 2 can be respectively abutted against two sides of the second sealing element 4, so that the second sealing element 4 can be fixed between the liquid storage container 1 and the shell of the rotary driving element 2 in the axial direction of the output shaft 20 of the rotary driving element 2, the second sealing element 4 is prevented from axially spreading along the output shaft 20, the stability of the second sealing element 4 is improved, the second sealing element 4 can effectively play a sealing role in the axial direction and the radial direction of the output shaft 20 of the rotary driving element 2, the liquid is prevented from flowing out from the first through opening of the liquid storage.
It should be noted that, since the second sealing member 4 is fixed between the side wall of the liquid storage container 1 where the first through opening is provided and the rotary driving member 2, when the output shaft 20 of the rotary driving member 2 rotates, relative friction is generated between the second sealing member 4 and the output shaft 20. Therefore, the first sealing element 3 can be made of wear-resistant material, and the abutting force between the second sealing element 4 and the side wall of the liquid storage container 1 and the abutting force between the second sealing element 4 and the rotary driving element 2 are adjusted to be smaller forces, so that the pressure on the second sealing element 4 can be reduced, the friction between the second sealing element 4 and the output shaft 20 can be reduced, and the second sealing element 4 is prevented from influencing the rotation process of the output shaft 20.
In practical applications, the shape of the first sealing member 3 and the shape of the second sealing member 4 are not limited as long as the hollow portion of the first sealing member 3 and the hollow portion of the second sealing member 4 can be sealingly sleeved on the output shaft 20 of the rotary driving member 2, and the shape of the outer peripheral wall of the first sealing member 3 and the shape of the outer peripheral wall of the second sealing member 4 may be any shape, such as a circle, an ellipse, a quadrangle, and the like.

Be provided with the second opening relative with first opening position on the stock solution container 1, spout and be provided with the import on the dish 6, spout one side that dish 6 is located the lateral wall that is provided with the second opening of stock solution container 1, and spout the import of dish 6 and stock solution container 1's second opening intercommunication. The output shaft 20 of the rotary driving member 2 sequentially passes through the first opening and the second opening of the liquid storage container 1 and then is connected with the spray disk 6 so as to drive the spray disk 6 to rotate.
The liquid in the liquid storage container 1 can flow into the spraying disc 6 from the second through hole of the liquid storage container 1, and the spraying disc 6 rotates to centrifugally atomize and spray the liquid entering the spraying disc 6 under the driving of the rotary driving piece 2, so that the spraying operation is realized.
Wherein, the spray disk 6 can be provided with a screw rod 60 in a penetrating way, one end of the screw rod 60 is fixedly connected with the output shaft 20 of the rotary driving member 2, the other end of the screw rod 60 penetrates through the spray disk 6 and then is connected with a screw cap 61, and the screw cap 61 is used for fixing the spray disk 6 on the screw rod 60.
As shown in fig. 2, the liquid storage container 1 includes a casing 10 and a cover 11, and the casing 10 covers the cover 11. The first opening of the liquid storage container 1 is provided on the case 10, and the second opening of the liquid storage container 1 is provided on the lid 11.
