The background art shows that the current air-assisted sprayer has the problems of single equipment use scene and poor universality due to the fact that the spraying range is smaller and the spraying direction is fixed, so that the air-assisted sprayer is difficult to adapt to different environments and use scenes. For this purpose, the present embodiment provides the following.

The present embodiment provides a spraying system, which is applied to unmanned equipment, and the unmanned equipment may be an unmanned vehicle suitable for traveling on the ground, and exemplary, the unmanned vehicle may be used for carrying a load to complete a predetermined task, for example, carrying an imaging device to perform shooting, carrying pesticides, nutrient solution and spraying devices to perform a plant protection task, and may also be used in other fields such as geographical mapping, aerial photography, electric inspection, environmental monitoring and disaster inspection.

Generally, the unmanned device includes a mobile platform 60 as a vehicle body, and the spraying system provided in the present embodiment may be disposed on the mobile platform 60, and the mobile platform 60 and the spraying system may both implement mobile control and spraying control through a control unit. During spraying operation, the control unit can send corresponding control signals to the mobile platform 60 and the spraying system according to the received signal content, so that the spraying system moves along with the mobile platform 60 to perform material spraying operation on the operation area. In some embodiments, the control unit can also realize automatic spraying operation of the unmanned equipment, so that the automation degree of the spraying system can be improved.

As shown in fig. 1-3, the mobile platform 60 is provided with a power assembly for providing power required for the motion of the mobile platform 60, and it is understood that the power assembly includes, but is not limited to, a power unit disposed in the mobile platform 60 and a movable wheel set movably disposed at the lower portion of the mobile platform 60 and in driving connection with the power unit.

As shown in fig. 1-5, the spray system includes a pan-tilt device 10, a spray device, and an air-moving device.

And the spray head 30 is communicated with the material cavity and is used for spraying the material loaded in the material cavity.

The air-blowing device comprises a wind-force device 40 and an air-blowing component 42, wherein the wind-force device 40 is used for increasing the pressure of air and exhausting high-pressure air in any direction, an air channel 421 for guiding the air is defined in the air-blowing component 42, and the wind-force device 40 is communicated with the air channel 421 so that the air with the pressure increased by the wind-force device 40 can be guided to flow along the extending direction of the air channel 421, and an air outlet 422 communicated with the air channel 421 is formed in the air-blowing component 42 so that the air can be exhausted from the air outlet 422 to the outside of the air-blowing device.

It should be appreciated that the material spraying range of the nozzle 30 at least partially coincides with the air discharging range of the air outlet 422, so that the high-pressure air flow generated by the air-feeding device can disturb the material sprayed by the spraying device, thereby allowing the material to move along the air flow direction and achieving the purpose of enhancing the material spraying range.

For example, the spray head 30 and the air supply member 42 are both disposed on the supporting portion 11, in some embodiments, the pan-tilt device 10 may simultaneously drive the spray head 30 and the air supply member 42 to rotate, and simultaneously change the spraying direction of the material and the air discharge direction, and in other embodiments, the pan-tilt device 10 may also respectively drive the spray head 30 and the air supply member 42 to rotate, so as to achieve adjustment of the spraying direction of the material and the air discharge direction. In an actual application scene, a user can send out corresponding control signals to the control unit through the mobile terminal or other control equipment, so that switching of different spraying operation modes is realized.

The spraying system realizes different spraying states through the cooperation of the spraying device, the air conveying device and the cradle head device 10, so that the spraying system can be correspondingly selected according to scene requirements. The structure can be obtained, and the spraying mode can realize at least four spraying operation modes, and the following modes are taken as examples of spraying liquid medicine on crops in plant protection scenes:

mode one: the spraying device is independently started, so that the spray head 30 sprays materials, and the spraying device is suitable for crops with low branch and leaf concentration or crops with low height, such as grape vine and the like, and can be directly sprayed through the spray head 30;

mode two: the spraying device cooperates with the cradle head device 10 to enable the spray head 30 to perform internal spraying operation within the rotation angle range preset by the cradle head device 10, and compared with the mode one, the spraying range of the spray head 30 can be enlarged, and the spray head is suitable for small-sized fruit trees, ground weeding and other operation environments;

mode three: the spraying device and the air conveying device work cooperatively, so that the air flow discharged by the air conveying device can disturb the material sprayed by the spraying device, further improve the spraying distance and strength of the material, enhance the penetrating power of the material spraying, and are suitable for crops with thick branches and leaves, promote the branches and leaves to shake and turn over, thereby improving the attachment rate of the material and not damaging the branches and leaves or fruits of the crops;

According to the above, the user can select the matched spraying mode according to different working environments and scenes, adapt to different environments and use scenes, improve the universality and realize one machine for multiple purposes.

Taking the material sprayed by the spraying device as the liquid, the spray head 30 can adopt the spray head 30, the spray head 30 can spray the pressurized water flow into the air to be atomized and scattered in the operation area, the specific structure of the spray head 30 is the conventional technology in the field, and the spray head 30 with the matched model can be selected according to the environmental characteristics of the required spraying operation, and the detailed description is omitted here.

In the application of unmanned equipment, the cradle head device 10 moves with the spraying device to change the material spraying direction of the spray head 30 and the air discharging direction of the air conveying device, so that the moving platform 60 can drive the cradle head device 10 to move, further the spraying range of the spraying system can be further enlarged, and the spraying efficiency of the spraying system can be improved.

It should be understood that in the above-described embodiments, the rotation axis of the pan/tilt head device 10 may be one or more, and in some embodiments, the spray head 30 may swing around a first direction relative to the pan/tilt head device 10, and the pan/tilt head device 10 may also swing around a second direction relative to the moving platform 60, where it is understood that the first direction and the second direction are perpendicular, so that the swing range and the amplitude of the spray head 30 can substantially meet different requirements of spraying operations.

Of course, in other embodiments, the nozzle 30 may also swing around the third direction and the fourth direction, which is not particularly limited in this embodiment.

To increase the spray range of the spray device, the spray device in some embodiments may include a plurality of spray heads 30, each spray head 30 being connected to a material tank, and the material tank providing the desired spray in a unified manner.

In the above embodiment, the orientation of each head 30 may be uniform or different from each other. In addition, the pan-tilt device 10 may drive each nozzle 30 to perform rotational movement at the same time, or may drive each nozzle 30 to perform independent rotational adjustment.

In this embodiment, the first direction is a vertical direction perpendicular to the horizontal plane, that is, the plurality of spray heads 30 are arranged at intervals along the vertical direction, so as to expand the spraying range of the spraying system in the height direction.

In other embodiments, the spray head 30 may be one, and in this embodiment, the structure and size of the spray nozzle formed on the spray head 30 may be selected according to the required spraying range, so as to achieve that the spraying range requirement of a part of the scene is primarily met in the case of one spray head 30.

Further, the air-feeding device may be provided with an air outlet 422, and the structural size of the air outlet 422 may be adaptively adjusted according to the arrangement mode of the spray heads 30 of the spraying device, so that the material sprayed by the spraying device may be disturbed by the air discharged by the air-feeding device, as shown in fig. 2, 4 and 7, taking the arrangement of an air outlet 422 as an example, the air outlet 422 is arranged to extend along the first direction and adjacent to each spray head 30.

For example, the number of the nozzles 30 of the spraying device may be determined according to the requirements of the working environment, and the number of the air outlets 422 of the air-sending device may be the same as the number of the nozzles 30, and may be greater than or less than the number of the nozzles 30. In the case that the number of the air outlets 422 is the same as that of the nozzles 30, the positions of the air outlets 422 may be in one-to-one correspondence with the nozzles 30, and be disposed on one side of the corresponding nozzle 30. In the case that the number of the air outlets 422 and the nozzles 30 is different, the air outlets 422 and the nozzles 30 may be alternately arranged along the first direction, or may be adjusted according to the actual working environment, which is not particularly limited in this embodiment.

For example, since the spraying system of the present embodiment needs to meet the spraying operation requirements of different operation environments through the cradle head device 10, the spraying device, and the air-assisted device. In order to improve the compactness of the fit between the devices, the spraying system further comprises a supporting body 50, wherein the supporting body 50 is used as a supporting structure of the whole spraying system, one side of the supporting body 50 is configured to be installed on a walking platform, a containing cavity 51 is defined in the supporting body 50, the containing cavity 51 is used for providing installation spaces of the tripod head device 10, part of the spraying device and part of the air delivery device, so that the tripod head device 10, the spraying device and the air delivery device can be installed on the supporting body 50 and supported and fixed by the supporting body 50, and it is understood that the spray head 30 and the air delivery component 42 can be arranged outside the supporting body 50 and installed with the supporting body 50 through supporting parts 11 in the corresponding devices. Wherein, the pan-tilt device 10, the spraying device and the air-assisted device are all connected with the mobile platform 60 through the supporting main body 50, and most parts can be loaded by the accommodating cavity 51, so that not only the effective protection (anti-collision, dust-proof, rain-proof and the like) of each device is realized, but also the spraying system is more integrated, the devices are more compact, and the mutual cooperative linkage operation is facilitated.

In order to allow the shower head 30 and the air blowing member 42 to be disposed outside the support body 50 and to realize relative movement with the movable platform 60 by the pan/tilt head device 10, the present embodiment provides the support body 50 with a clearance portion communicating with the accommodating chamber 51, the pan/tilt head device 10 is disposed entirely within the accommodating chamber 51, and the support portion 11 is exposed outside the support body 50 through the clearance portion so that the shower head 30 and the air blowing member 42 are disposed on the support body 50. As shown in fig. 4, a fixing structure capable of being fixedly connected with the movable platform 60 is provided at the bottom of the supporting body 50, a space avoiding portion communicating with the internal accommodating cavity 51 is provided at the upper portion of the supporting body 50, and the air supply member 42 and the nozzle 30 are mounted on the supporting portion 11 exposed to the space avoiding portion, so that the problem of interference between the nozzle 30 and the air outlet 422 when extending in the vertical direction and the supporting body 50 is avoided.

In order to further improve the compactness of the spraying system, the present embodiment adopts a manner that the pan-tilt device 10 drives the spraying device and the air-blowing device to rotate at the same time, as shown in fig. 4-5, the spraying system further includes a movable base 41, and the movable base 41 is used as a supporting part 11 of the nozzle 30 and the air-blowing component 42, and is mounted on the supporting part 11, so that the pan-tilt device 10 can drive the movable base 41 to rotate around the rotation axis thereof. The shower nozzle 30 and the air supply component 42 are all arranged on the movable base 41, so that the cradle head device 10 can drive the shower nozzle 30 and the air supply component 42 to rotate simultaneously through the movable base 41, the arrangement mode can enable the shower nozzle 30 and the air outlet 422 to keep adjacent arrangement, the air discharged by the air outlet 422 can disturb the material sprayed by the shower nozzle 30 in any rotation direction, the quantity of the material can be relatively reduced, and independent supporting structures are not required to be designed for the shower nozzle 30 and the air supply component 42 respectively, so that the integrated design of unmanned equipment is facilitated.

In order to ensure that the plurality of spray heads 30 can be stably mounted in the first direction, the first section of the guide pipeline 31 is inserted into the movable base 41, so that the guide pipeline 31 rotates along with the movable base 41, and the guide pipeline 31 can penetrate through the movable base 41 to be connected with the load container 20, in the embodiment, an opening for connecting the first section of the guide pipeline 31 is formed in the side part of the movable base 41, so that a sufficient mounting space is provided for part of components of the air conveying device in the movable base 41, and the spraying device is reasonably and compactly matched with the air conveying device. The second end of the guide pipe 31 can provide the installation position of the spray heads 30, the user can adjust the second section structure of the guide pipe 31 according to the requirement of the working environment and the mode of the layout required by the spray heads 30, and the user can install a corresponding number of spray heads 30 on the second section structure of the guide pipe 31 and set the intervals of the spray heads 30 to be the preset size according to the requirement. In this embodiment, the plurality of spray heads 30 are arranged at intervals along the first direction, and the second section of the guide pipeline 31 may be provided as a straight pipe and vertically extend along the first direction, and the spray heads 30 are mounted on the second section of the guide pipeline 31, so that the material can be uniformly conveyed to each spray head 30 along the guide pipeline 31, and the material can be uniformly sprayed along the first direction.

In some embodiments, to ensure that the material can be disturbed by the air, the second section of the guide pipeline 31 may be disposed at the air outlet 422, for example, the second section of the guide pipeline 31 is configured in a "U" shape, and the air outlet 422 is disposed between the second sections of the two guide pipelines 31 along the first direction, so that the material sprayed from the nozzles 30 at both sides can be disturbed by the air flow discharged from the air outlet 422, which is helpful for uniform spraying in the cooperative operation mode of the spraying device and the air-conveying device. However, in this embodiment, in order to avoid the material spraying ranges of the spray heads 30 from interfering with each other, the spray heads 30 on both sides should be alternately arranged along the first direction.

As shown in fig. 4 to 7, in the case that the guide pipeline 31 is a straight pipe, the air supply component 42 of the present embodiment surrounds the periphery of the second section of the guide pipeline 31 to form the air outlet 422, at least two sides of the material sprayed by the nozzle 30 can be disturbed by the air discharged by the air outlet 422, so that the material is ensured not to deviate in the spraying direction due to the fact that the air outlet 422 is only arranged at one side of the nozzle 30, a uniform air field is provided for the material, the material spraying uniformity is effectively improved, and more air acts on the material, and the penetrating power of the material under the condition of intervening operation of the air supply device can be further improved.

Of course, the penetration force may also be determined by the pressure of the material sprayed from the spray head 30 and the flow rate of the gas discharged from the air outlet 422. In some embodiments, the user can also control the material spraying amount of the spraying device and the air output amount of the air conveying device by sending corresponding signals to the control unit.

In one embodiment, to pressurize the material, which is initially forced out of the spray head 30, the spray device further includes an electrically powered pump body 32. In some embodiments, the specific model and structure of the electric pump body 32 are not particularly limited, and in the case that the spraying material is a liquid medicine, the electric pump body 32 may be a diaphragm pump, and the diaphragm pump can effectively separate the liquid medicine from the plunger and the pump cylinder, so as to protect the plunger and the pump cylinder, and in the embodiment of spraying the liquid medicine, the service life of the electric pump body can be prolonged.

Generally, the electric pump body 32 includes a liquid inlet end and a liquid outlet end, the liquid inlet end is communicated with the material cavity through a liquid inlet pipeline (not shown), and the liquid outlet end of the electric pump body 32 is communicated with the guide pipeline 31 through a liquid outlet pipeline 33. It will be appreciated that the electric pump body 32 may be disposed in the accommodating cavity 51 formed by the supporting body 50 to protect the electric pump body 32, while the load container 20 may be disposed outside the supporting body 50 for facilitating the addition of materials, and the load container 20 may be disposed with an electronic liquid level meter in the material cavity, and the electronic liquid level meter is electrically connected to the control unit, so as to monitor the storage of the liquid medicine, such as by alarming when the liquid medicine is about to be consumed or prompting on the mobile terminal, so as to remind the user of even supplementing the liquid medicine.
