[0058] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0060] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0061] Spraying equipment has a wide range of applications. For example, in agricultural and forestry plant protection, it sprays pesticides, growth regulators, and other liquids onto target areas; in pest control, it sprays bactericides and disinfectants onto target areas; and so on. Many spraying devices used in agricultural and forestry plant protection and pest control scenarios employ pressure atomization technology, using compressed air or high-pressure nitrogen as power to propel liquids (such as pesticides) through nozzles, breaking them down into fine droplets. However, these pressure atomization spraying devices generally have limited atomization effectiveness and their applicability is limited in some scenarios. For example: first, the droplet size produced by pressure atomization may be large and unevenly distributed; second, it has poor controllability, making precise atomization control difficult; and third, the nozzles are prone to clogging.

[0062] Based on this, this application provides a centrifugal atomizing device suitable for use in centrifugal atomizing spraying equipment including a fan. This centrifugal atomizing device generates centrifugal force through a high-speed rotating centrifugal atomizing disc, using this force to throw the liquid out. During this throwing process, the liquid is dispersed and atomized into fine liquid particles, which are then sprayed out of the centrifugal atomizing disc as atomized droplets. Compared to pressure atomization, centrifugal atomization provides better atomization results and is suitable for application in the field of agricultural and forestry plant protection pesticide spraying.

[0063] The centrifugal atomizing device of this application is further equipped with an outer cover. Several baffles surround the outer periphery of the centrifugal atomizing disc to protect the high-speed rotating disc. When using the centrifugal atomizing device to spray liquids (such as pesticides) onto agricultural and forestry crops, it prevents foreign objects such as branches and twigs from reaching the vicinity of the centrifugal atomizing disc and causing damage. The outer cover also prevents crops from being damaged by the centrifugal atomizing disc and avoids injury to operators from disc breakage.

[0064] This application also provides a centrifugal atomizing spraying device, which can be installed on mobile plant protection equipment, such as unmanned vehicles or unmanned aerial vehicles, or it can be used fixed in the environment. Handheld use is also possible. The centrifugal atomizing spraying device uses a centrifugal atomizing device at its front end to spray atomized droplets radially, while a fan at the rear of the centrifugal atomizing device blows air towards the target area. This centrifugal atomizing spraying device can expand the coverage area of ​​the fog field, and the spraying operation is highly efficient and effective.

[0065] This application also provides a mobile platform, which can be, but is not limited to, driverless vehicles or manned vehicles.

[0066] It should be noted that, in order to facilitate the description of the relative positions between the centrifugal atomizing device and the various components inside the centrifugal atomizing spraying equipment, the y-direction and x-direction are marked in the accompanying drawings. The y-axis direction is consistent with the central axis of the centrifugal atomizing spraying device and the central axis of the centrifugal atomizing spraying equipment, and the x-direction is the radial direction.

[0067] Please refer to Figures 1 to 14 The following describes the centrifugal atomizing device of this application (such as...). Figures 1 to 11 (Illustrative image) Centrifugal atomizing spraying equipment 100 (e.g.) Figure 12 , Figure 13 (Illustrative) and mobile platforms (such as) Figure 14 Indication, Figure 14 The structure of the mobile platform (for unmanned vehicles) will be described in detail.

[0068] Reference Figures 1 to 11Centrifugal atomizing devices are used to create a forward-blowing atomized airflow in conjunction with airflow. For example, in a geodetic coordinate system, if the centrifugal atomizing device is located on the left, and the airflow blows from right to left from the rear of the device, the droplets ejected by the device can form a left-blowing atomized airflow under the influence of the airflow. As another example, in a geodetic coordinate system, if the centrifugal atomizing device is located at the bottom, and the airflow blows from back to front from the rear, the droplets ejected can form a downward-blowing atomized airflow under the influence of the airflow.

[0069] The centrifugal atomizing device includes a main body, a centrifugal atomizing disc 10, and an outer cover 40. The main body includes a flow guiding device 20. Optionally, the main body also includes a driving device 30.

[0070] The flow guiding device 20 is used to deliver liquid to the centrifugal atomizing disk 10. The driving device 30 includes a fixed base 31 and a driving part. The fixed base 31 of the driving device 30 is connected to and fixed relative to the flow guiding device 20, and the driving part is connected to the centrifugal atomizing disk 10. The driving device 30 is used to drive the centrifugal atomizing disk 10 to rotate around a first axis, which is the central axis of the centrifugal atomizing disk 10.

[0071] For example, the centrifugal atomizing disk 10 is provided with a plurality of atomizing channels 1201 distributed around a first axis. The flow guiding device 20 provides the flow guiding channel and is used to connect with the liquid supply device and to transport the liquid from the liquid supply device to the centrifugal atomizing disk 10 so that the liquid can enter the plurality of atomizing channels 1201. The driving device 30 can be, but is not limited to, a motor. By driving the centrifugal atomizing disk 10 to rotate, the liquid can be centrifugally thrown out, so that the atomized droplets are sprayed out around the centrifugal atomizing disk 10.

[0072] The outer cover 40 includes several baffles 42 surrounding the outer periphery of the centrifugal atomizing disk 10, and the baffles 42 extend downstream of the airflow. The centrifugal atomizing device is located at the air outlet of the air supply mechanism (such as a fan), so that the centrifugal atomizing disk 10 is under the action of the airflow field. A protective cover (including several baffles 42 surrounding the outer periphery of the centrifugal atomizing disk 10) is provided on the outer periphery of the centrifugal atomizing disk 10. The baffles 42 of the protective cover extend in the direction of the airflow to form a long strip structure, so as to prevent the droplets thrown out by the centrifugal atomizing disk from accumulating on the baffles 42 when they are blown onto the baffles 42 of the cover by the airflow.

[0073] Optionally, the outer cover 40 includes a cover mounting portion 41 and a plurality of spacers 42, the spacers 42 being connected to the cover mounting portion 41. The cover mounting portion 41 is connected to the main body of the device, see reference. Figures 1 to 6 , Figure 12A plurality of partitions 42 surround the outer periphery of the centrifugal atomizing disk 10, with adjacent partitions 42 spaced apart. In this way, the plurality of partitions 42 surrounding the outside of the centrifugal atomizing disk 10 can protect the centrifugal atomizing disk 10.

[0074] The baffle 42 extends away from the drive device 30. Optionally, the baffle 42 is a strip structure extending axially. The centrifugal atomizing disk 10 has a certain axial height. By using the baffle 42 extending a certain distance along the axis around the outer periphery of the centrifugal atomizing disk 10, the protective effect, the deceleration of the droplets, and the effect of secondary atomization of the droplets are all better.

[0075] This centrifugal atomizing device can be used to spray pesticides on crops. For example, a centrifugal atomizing spraying device 100 is mounted on a mobile platform. The centrifugal atomizing spraying device 100 includes the centrifugal atomizing device and a fan 61, etc. When it is necessary to spray pesticides on agricultural and forestry crops such as dragon fruit plants and corn plants, the unmanned vehicle moves in the field, the centrifugal atomizing device works to throw and spray atomized droplets around the centrifugal atomizing disc 10, and the fan 61 blows the atomized droplets toward the target plants.

[0076] This centrifugal atomizing device generates centrifugal force through a high-speed rotating centrifugal atomizing disk 10. This centrifugal force propels the liquid outwards, breaking it down into fine droplets that are then ejected from the centrifugal atomizing disk 10. Compared to pressure atomization, centrifugal atomization provides superior atomization results and is suitable for application in agricultural and forestry plant protection pesticide spraying.

[0077] The centrifugal atomizing device of this application has good atomization effect: First, it can disperse liquid into smaller droplets, and the droplet size can be controlled to be more uniform, avoiding the situation where some droplets are very large and some are very small; Second, it can form a wider spray coverage area, allowing the liquid to cover the target area more evenly, resulting in better spraying effect; Third, it has strong adjustability, and the droplet size and spray volume can be controlled by adjusting parameters such as rotation speed and liquid flow rate to meet different operational needs and achieve precise atomization control; Fourth, compared with pressure nozzles, the flow channels inside the centrifugal atomizing disc 10 are less prone to clogging.

[0078] The outer cover 40 serves to protect the centrifugal atomizing disc 10. For example, if corn leaves or other leaves or foreign objects accidentally extend into the area near the centrifugal atomizing disc 10, they will first be blocked by the baffles 42 surrounding the disc 10. The baffles 42 of the outer cover 40 prevent leaves or other foreign objects from approaching the centrifugal atomizing disc 10. Specifically, when the centrifugal atomizing disc 10 is rotating, the baffles 42 prevent leaves or other foreign objects from being drawn into the disc, thus preventing damage to the disc or the crop. When the centrifugal atomizing disc 10 is in a standby state without rotation, the baffles 42 prevent leaves or other foreign objects from scratching or damaging the disc 10. It is understandable that the adjacent baffles 42 are spaced apart from each other, and a passage 4201 is formed between the adjacent baffles 42. The passage 4201 allows the atomized droplets thrown out by the centrifugal atomizing disc 10 to pass through. The setting of the outer cover 40 does not affect the function of the centrifugal atomizing disc 10 to throw out atomized droplets.

[0079] In the centrifugal atomizing device of this application, the centrifugal atomizing disc 10 is surrounded by a number of baffles 42 of the outer cover 40, which can protect the centrifugal atomizing disc 10 from being damaged by foreign objects, protect crops from being damaged by the centrifugal atomizing disc 10, and protect personnel from injury caused by the breakage of the centrifugal atomizing disc 10. This can solve the problem caused by the direct exposure of the centrifugal atomizing disc 10.

[0080] Reference Figures 12 to 14 The centrifugal atomizing spraying device 100 includes the centrifugal atomizing device of this application, and also includes a fan 61. The centrifugal atomizing disc 10, the device body, and the fan 61 are arranged axially. The centrifugal atomizing device is used to atomize the liquid to be sprayed through the centrifugal atomizing disc 10, and to spray the atomized liquid approximately radially out of the centrifugal atomizing spraying device 100 through the centrifugal atomizing disc 10. The spray effect of the centrifugal atomizing disc 10 is similar to... Figure 13 The diagram is similar to ( Figure 13 The bold dashed lines in the text are only used to illustrate the droplet path and cannot be considered the sole limitation of this application. The blower 61 is located at the axial rear of the centrifugal atomizing disk 10, and the blower 61 is used to blow the droplets ejected from the centrifugal atomizing disk 10 toward the target area.

[0081] This centrifugal atomizing spraying device 100 can spray pesticides using a centrifugal atomizing disc 10 in conjunction with a blower 61. Compared with conventional pressure atomizing spraying, it has the following advantages: better atomization effect; it can obtain finer atomized droplets, and these fine droplets, combined with the wind blowing action, can penetrate the crop canopy more deeply, covering more leaves and fruit surfaces, thus improving pesticide utilization and control efficacy; the centrifugal atomizing spraying device can control the rotation speed by adjusting the motor voltage, thereby precisely controlling the droplet size. This flexibility allows for more precise pesticide spraying. It can be precisely adjusted according to different crop types, growth stages, and pest and disease conditions; centrifugal atomization spraying is suitable for a variety of pesticide formulations, including but not limited to powders, suspensions, emulsifiable concentrates, and other pesticides with poor water solubility, thus expanding the range of pesticide choices; it can improve spraying efficiency, as centrifugal atomization spraying combined with blower 61 can deliver droplets directly to the target area, reducing pesticide dispersion and waste in the air and improving spraying efficiency; it is not only suitable for pesticide spraying in large areas of farmland, but also for the fine management of small-scale crops such as orchards and vegetable gardens.

[0082] The mobile platform of this application, equipped with a centrifugal atomizing spraying device 100, and in conjunction with the centrifugal atomizing spraying device, a fan 61, and an unmanned vehicle mobile body 200, enables the unmanned vehicle to move in the field and automatically spray pesticides. The technology of this application has high application value in modern agriculture. This spraying method is suitable for a variety of crops and has advantages such as adjustable spray volume, adjustable droplet size, good atomization spraying effect, improved work efficiency, and reduced labor costs.

[0083] The mobile platform of this application is suitable for spraying pesticides on various types of crops. For example, for low-growing crops (peanuts, sweet potatoes, etc.), the centrifugal atomizing sprayer can easily cover all parts of the plant by adjusting the angle of the centrifugal atomizing sprayer 100°, ensuring uniform pesticide spraying. For medium-growing crops (cotton, soybeans, trellis cucumbers, trellis eggplants, corn, lemons, wheat, etc.), the centrifugal atomizing device, in conjunction with a suitable fan 61, can effectively blow pesticide droplets onto the leaves and stems of the crop, improving the spraying effect.

[0084] The mobile platform is equipped with a centrifugal atomizing spraying device 100. The mobile platform can adjust its travel speed according to the height and density of the crops. The spraying angle can be adjusted by adjusting the angle of the centrifugal atomizing spraying device 100 to accurately spray the target area.

[0085] This mobile platform is an unmanned vehicle, and when applied to agricultural and forestry plant protection, it can travel in fields such as farmland, orchards, and vegetable gardens. Figure 14The illustration shows that spraying pesticides onto crop plants from the side yields good results. The centrifugal atomizing spraying device 100 of this unmanned vehicle, due to its centrifugal atomization device combined with a blower 61, provides droplets with a certain degree of penetration. The droplets can more accurately reach the target crop plants, and their small size and uniform distribution allow them to enter the interior of the crop plant through the gaps between leaves, facilitating more complete coverage of leaves and fruits. This improves the problem of uneven pesticide application between the outer and inner areas of the crop (e.g., the outer edges of leaves may receive pesticide, but the roots may not), and also improves the uneven application between the top and bottom of the crop, thus enhancing the pest control effect.

[0086] In one embodiment, to achieve better spraying results, the centrifugal atomizing device is configured such that, when the centrifugal atomizing device is in the atomizing spraying working state, the rotation axis of the centrifugal atomizing disk 10 is parallel to the horizontal plane or the angle between it and the horizontal plane is less than 30 degrees. Figure 14 The diagram illustrates that when the centrifugal atomizing device is in operation, the back of the centrifugal atomizing disc 10 is approximately to the left or right. With the help of the fan 61, it can spray the liquid medicine onto the plants on the left or right side of the movable platform 200. In the diagram, L1 indicates the rotation axis of the centrifugal atomizing disc 10, and L2 indicates the horizontal plane. The rotation axis L1 of the centrifugal atomizing disc 10 is basically parallel to the horizontal plane L2. That is, the axial direction of the centrifugal atomizing device is arranged in an approximately horizontal direction, and the rotation plane of the centrifugal atomizing disc 10 is set approximately along a vertical plane perpendicular to the horizontal plane.

[0087] The inventors discovered that when an outer cover 40 is provided in the centrifugal atomizing device, during the operation of the centrifugal atomizing device, the centrifugal atomizing disk 10 rotates to spin and throw out atomized droplets, and some droplets may settle on the baffle 42. Among them, the settled droplets are the droplets that were not sprayed out and remain nearby.

[0088] If the outer cover 40 is fixed in position during the atomization process, for the case where the centrifugal atomizing device is mounted on a drone, the centrifugal atomizing device is generally positioned above the crop. When the drone sprays the liquid downwards, the baffle 42 extends downwards, and large droplets are not easy to accumulate on the baffle 42, or the accumulated large droplets will drip down to the ground along the baffle 42 under their own weight.

[0089] However, when the centrifugal atomizing device is mounted on a mobile platform, it typically sprays the pesticide onto the crop from the side (e.g., left or right). In many cases, the axis of the centrifugal atomizing disc 10 is parallel to the ground plane (e.g., when spraying horizontally to the left), or the axis of the centrifugal atomizing disc 10 is at a certain angle to the ground plane (e.g., when spraying towards the upper left or lower left). Thus, the baffle 42 is mostly parallel to the ground plane or at an angle within 45 degrees to the ground plane. In this case, droplets may accumulate on the baffle 42, forming sedimentation. The sedimentation and accumulation of droplets on the baffle 42 may cause one or more of the following problems:

[0090] First, the droplets that settle on the baffle 42 are visible to the user, making the user feel that these droplets are not blown out, which feels wasteful and affects the user experience.

[0091] Second, if the droplets fall downwards only after the centrifugal atomizing device has stopped working, they may fall onto the moving body 200 and contaminate the moving body 200.

[0092] First, in some cases, these droplets accumulated on the baffle 42 may be drawn back by the fan 61, and the drawn-back droplets may contaminate the flow guiding device 20, the drive device 30, and the fan 61.

[0093] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The centrifugal atomizing device configures the outer cover 40 to be rotatable. The outer cover 40 is rotatably connected to the flow guide device 20, or the outer cover 40 is rotatably connected to the mounting base 31 (such as a motor mount) of the drive device 30.

[0094] Optionally, the flow guide device 20 is provided with an annular connecting rail 71, and the cover mounting part 41 of the outer cover 40 is rotatably mounted on the connecting rail 71.

[0095] Optionally, based on the rotatable installation of the outer cover 40, the outer cover 40 in the centrifugal atomizing device and centrifugal atomizing spraying equipment 100 is configured such that, when the centrifugal atomizing device is in operation, the rotation direction of the outer cover 40 is opposite to the rotation direction of the centrifugal atomizing disk 10. That is, the centrifugal atomizing disk 10 rotates around a first direction to spray atomized droplets outward, and the outer cover 40 rotates around a second direction, with the first direction and the second direction being opposite. For example, the first direction is clockwise and the second direction is counterclockwise, or vice versa. It can be understood that when the centrifugal atomizing device is working, the outer cover 40 rotates in the opposite direction to the centrifugal atomizing disk 10. When the droplets ejected by the centrifugal atomizing disk 10 hit the baffle 42, due to the counterclockwise rotation of the outer cover 40, the baffle 42 has a movement tendency opposite to that of the droplets, making it easier for the droplets to leave the baffle 42.

[0096] When the centrifugal atomizing device is working, the outer cover 40 rotates in opposite directions to the centrifugal atomizing disk 10, which can bring at least one of the following effects:

[0097] First, it can reduce the amount of liquid settling on the partition 42, avoid or reduce the formation of a small number of large droplets on the partition 42, thereby improving the user experience and preventing the droplets settling on the partition 42 from dripping and contaminating other areas.

[0098] Secondly, in the centrifugal atomizing spraying device 100 of this application, the baffle 42 of the reverse-rotating outer cover 40 can reduce the speed of the centrifugally sprayed droplets, making it easier for the droplets to be controlled by the wind field blown by the fan 61, so that the atomized droplets can be stably blown by the fan 61 to the target area, making the fog field more stable.

[0099] Optionally, when the centrifugal atomizing device is in operation, the rotation direction of the outer cover 40 is opposite to the rotation direction of the centrifugal atomizing disk 10, and the rotation speed of the outer cover 40 is lower than that of the centrifugal atomizing disk 10.

[0100] It should be noted that the 40-degree rotatable centrifugal atomizing device can be installed in both unmanned vehicle and drone applications.

[0101] In other embodiments, the outer cover 40 may also be configured to be non-rotatable, with the outer cover 40 fixed relative to the flow guide 20.

[0102] In one embodiment, the rotation of the outer cover 40 is achieved by driving the drive device 30, in which case the outer cover 40 is configured to rotate actively. Alternatively, the rotation of the outer cover 40 is driven by the air blown by the fan 61, in which case the outer cover 40 is configured to rotate actively. Another option is that the rotation of the outer cover 40 is caused by droplets centrifugally ejected by the centrifugal atomizing disc 10 striking the outer cover 40, thus causing the outer cover 40 to rotate.

[0103] The following are several ways to rotate the outer cover 40 degrees.

[0104] One method of rotating the outer cover 40 is as follows: The outer cover 40 includes a cover mounting part 41 and several fan blades 44. The cover mounting part 41 is rotatably connected to the main body of the device. For example, the cover mounting part 41 is rotatably connected to the flow guiding device 20, and several fan blades 44 surround the cover mounting part 41. In this way, when the centrifugal atomizing device is applied in the centrifugal atomizing spraying equipment 100 with a blower 61, the air blown by the blower 61 is used to blow the atomized droplets centrifuged by the centrifugal atomizing disc 10 toward the target object. The air blown by the blower 61 can also act on the fan blades 44 of the outer cover 40 to drive the outer cover 40 to rotate. By controlling the rotation direction of the fan blades 44, the centrifugal atomizing device can be in working condition, and the rotation direction of the outer cover 40 is opposite to the rotation direction of the centrifugal atomizing disc 10.

[0105] The second rotation method for the outer cover 40: In the centrifugal atomizing device, a driver is included, which is connected to the outer cover 40 and used to drive the outer cover 40 to rotate. The drive device 30 used to drive the centrifugal atomizing disc 10 to rotate can be, but is not limited to, a motor, and the driver used to drive the outer cover 40 to rotate can be, but is not limited to, a motor. The required rotational speed of the outer cover 40 does not need to be too high.

[0106] Optionally, the centrifugal atomizing device is configured such that, when the centrifugal atomizing device is in operation, the rotation direction of the outer cover 40 is opposite to the rotation direction of the centrifugal atomizing disk 10.

[0107] The third rotation method of the outer cover 40: In the centrifugal atomizing device, the driving device 30 includes a fixed base 31 and a driving part, which is a driving shaft 32. The centrifugal atomizing disk 10 and the outer cover 40 are driven to rotate in opposite directions through the same driving shaft 32. For example, the end of the driving shaft 32 is connected to the centrifugal atomizing disk 10, and the outer cover 40 is fitted over the driving shaft 32. A transmission assembly is provided between the outer cover 40 and the driving shaft 32. When the driving shaft 32 rotates in the forward direction, the centrifugal atomizing disk 10 rotates in the forward direction. Through the transmission assembly, the driving shaft 32 can drive the outer cover 40 to rotate in the reverse direction.

[0108] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 7 , Figure 10 The centrifugal atomizing disk 10 includes a disk body 11 and at least one atomizing group. The disk body 11 has an atomizing surface 1101, and the atomizing group is disposed on the atomizing surface 1101. Each atomizing group includes atomizing protrusions 12 spaced apart around the center line of the disk body 11, and an atomizing flow channel 1201 is formed between adjacent atomizing protrusions 12.

[0109] The baffle 42 in the outer casing 40 also serves to reduce the droplet velocity of the centrifugal atomizing disc 10 and to perform secondary atomization of the droplets. In the centrifugal atomizing disc 10, the outermost atomizing group, such as... Figure 2 , Figure 10 The width of the atomizing channel 1201 is shown as d1. A passageway 4201 is formed between adjacent partitions 42, as shown... Figure 2 The width of channel 4201 is shown as d2.

[0110] The density of the partitions 42 in the outer cover 40 needs to be reasonably configured. The density of the partitions 42 is controlled by d2 / d1 < 8. The larger the value of d2 / d1, the sparser the partitions 42 of the outer cover 40 are, and the smaller the value of d2 / d1, the denser the partitions 42 of the outer cover 40 are.

[0111] The density of the baffles 42 in the outer casing 40 affects the spraying effect of the centrifugal atomizing device on the outer periphery. If the baffles 42 in the outer casing 40 are too dense, the spray volume will be reduced. If the baffles 42 in the outer casing 40 are too sparse, the protective effect of the baffles 42 is limited, and more atomized droplets sprayed from the centrifugal atomizing disk 10 will be sprayed directly out of the centrifugal atomizing device through the passage 4201 without contacting the baffles 42. The effect of the baffles 42 in slowing down the droplets sprayed from the centrifugal atomizing disk 10 and in secondary atomization is also limited. By controlling the density of the baffles 42 by d2 / d1 < 8, the outer casing 40 can simultaneously protect the centrifugal atomizing disk 10, slow down the droplets to make the air field easier to control the atomized droplets, provide secondary atomization for the droplets, and prevent the formation of large droplets or settling droplets at the baffles 42.

[0112] Optionally, 1 ≤ d2 / d1 < 4. The spacing between the partitions 42 shall not be less than the spacing between the outermost atomizing protrusions 12, so as to avoid reducing the spray volume and affecting the air-assisted spraying effect.

[0113] In one embodiment, reference is made to Figure 8 , Figure 9 The baffle 42 is an atomizing tooth, and its inner side has a tip 421. The inner side of the baffle 42 refers to the side of the baffle 42 that is close to the centrifugal atomizing disk 10 and the side of the baffle 42 that is close to the central axis of the outer cover 40. The tip 421 is used to disperse droplets. When droplets ejected by the centrifugal atomizing disk 10 come into contact with the tip 421 of the baffle 42, the droplets are dispersed again by the tip 421 of the baffle 42, thereby achieving the effect of re-atomization of the droplets.

[0114] It should be noted that whether the outer cover 40 is rotatably or non-rotatably installed, when the outwardly ejected droplets collide with the tip 421 of the baffle 42, they will have the effect of re-atomizing the droplets.

[0115] In other embodiments, the inner end of the partition 42 may not be the pointed tip 421. The partition 42 may also be cylindrical or the like.

[0116] In one embodiment, reference is made to Figure 12 , Figure 13 The centrifugal atomizing spraying device 100 also includes an air guide shroud 62. The air guide shroud 62 has an air inlet and an air outlet (illustrated but not marked in the figure) at its two axial ends. The end of the air guide shroud 62 with the air inlet is connected to the fan 61. Through its specific design shape, the air guide shroud 62 can guide the surrounding airflow along a predetermined path. When used in conjunction with the fan 61, the air guide shroud 62 allows the mist droplets to be more accurately delivered to the target area under the action of wind, reducing mist droplet dispersion and waste, and lowering the power requirements of the fan 61.

[0117] The main body of the centrifugal atomizing device is located inside the air guide shroud 62, meaning the air guide shroud 62 at least covers the outside of the main body. Optionally, the mounting base 31 of the drive device 30 is connected to the fan 61, so the drive device 30 is at least located inside the air guide shroud 62. The position of the centrifugal atomizing disc 10 can be in the following two ways:

[0118] First, such as Figure 12 , Figure 13 As shown, in the axial direction of the centrifugal atomizing spraying device 100, the centrifugal atomizing disc 10 is located outside the air guide shroud 62, that is, the centrifugal atomizing disc 10 is located on the side of the air guide shroud 62 away from the fan 61, and the air guide shroud 62 does not cover the outer periphery of the centrifugal atomizing disc 10.

[0119] Understandably, when the centrifugal atomizing sprayer 100 is mounted on an unmanned vehicle, it is used to spray pesticides onto crops to the side of the vehicle, such as to the left, right, front, and rear of the vehicle. By placing the centrifugal atomizing disc 10 outside the air guide shroud 62, preventing the shroud 62 from surrounding the outer edge of the disc, during spraying operations (e.g., when the centrifugal atomizing sprayer 100 is configured to spray pesticides to the left or upper left of the vehicle), a small portion of the droplets sprayed outwards from the disc 10 are reduced or prevented from floating in the air and eventually settling on the inner wall of the air guide shroud 62. This reduces the possibility of droplets forming on the inner wall of the air guide shroud 62, minimizing pollution and waste, and improving the user experience.

[0120] It is also understandable that when the centrifugal atomizing disc 10 is located outside the air guide shroud 62, the outer cover 40 has several baffles 42 surrounding the outer periphery of the centrifugal atomizing disc 10, which serve to protect the exposed centrifugal atomizing disc 10.

[0121] Second, not shown in the figure, the centrifugal atomizing disc 10 is located inside the air guide shroud 62 in the axial direction of the centrifugal atomizing spraying device 100.

[0122] In one embodiment, the air guide shroud 62 is provided with a main air supply duct, the two ends of which are connected to an air inlet and an air outlet, respectively. (Refer to...) Figure 13 In the radial direction of the centrifugal atomizing spraying device 100, the baffle 42 is located between the centrifugal atomizing disc 10 and the main air supply duct. (Refer to...) Figure 13 The centrifugal atomizing spraying device 100 can be radially divided into a central region, a transition region, and an air supply region. The central region, transition region, and air supply expansion region all extend axially, with the transition region surrounding the outer periphery of the central region and the air supply expansion region surrounding the outer periphery of the transition region. The centrifugal atomizing disc 10 is located in the central region, several baffles 42 of the outer casing 40 are located in the transition region, and the main air supply duct is located in the air supply region. For example, Figure 16 It indicated Figure 15 Schematic diagram of each region in the middle. Figure 16 In this diagram, S1 is the aforementioned central region, S2 is the aforementioned transition region, and S3 to S8 surround the outer perimeter of the transition region. S3 is the position blocked by the first tongue 622, S4 is the region blocked by the second tongue 623, and S5 to S8 are all air supply regions. Regions S5 and S6 are the air outlets of the main air supply duct (S5 and S6 are located on the upper and lower sides of the centrifugal atomizing disk 10), and S7 and S8 are the air outlets of the front-to-back through air duct (S7 and S8 are located on the left and right sides of the centrifugal atomizing disk 10). The droplets, after being ejected from the central region S1, pass through the transition region S2 where the baffle 42 is located, and are effectively blown forward upon reaching regions S5 to S8. Of course, some droplets may also be blown forward after leaving the transition region. In other embodiments, the position of the air duct outlets may also be adjusted.

[0123] Understandably, the baffle 42 is positioned in the transition area to reduce droplet velocity and make it easier for the airflow to control the droplets, thus stabilizing the fog field. The droplets sprayed outwards from the centrifugal atomizing disc 10 first pass through the transition area. When the droplets collide with the baffle 42 on the outer cover 40 in the transition area, the baffle 42 reduces the radial centrifugal velocity of the droplets. This makes it easier for the droplets to be controlled by the forward-blowing airflow when they reach the air delivery area, allowing the airflow to propel the droplets forward and making the fog field of the centrifugal atomizing spraying device 100 more stable.

[0124] It is also understandable that the baffle 42 is placed in the transition area, which is beneficial for secondary atomization of the droplets. In centrifugal atomizing spraying equipment 100, if a smaller droplet size is desired, increasing the rotational speed of the centrifugal atomizing disk 10 is generally considered. However, the inventors have found that increasing the rotational speed of the centrifugal atomizing disk 10 may cause the droplets to maintain a high radial centrifugal velocity when they reach the air delivery area. Therefore, to obtain a stable mist field, the wind speed of the fan 61 needs to be increased. However, in this embodiment, the baffle 42 of the outer cover 40 surrounds the outer periphery of the centrifugal atomizing disk 10. Thus, the baffle 42 can further disperse and atomize the droplets, reducing the droplet size. This allows for the acquisition of smaller droplets without increasing the rotational speed of the centrifugal atomizing disk 10 or the wind speed of the fan 61.

[0125] Optionally, refer to Figure 12 The air guide shroud 62 includes an air guide housing 621 and a first tongue 622 and a second tongue 623 disposed inside the air guide housing 621. The first tongue 622 and the second tongue 623 are located on opposite sides of the centrifugal atomizing device. The main air supply duct includes a first expansion duct 6201 and a second expansion duct 6202. The first expansion duct 6201 is formed between the inner wall of the air guide housing 621 and the first tongue 622, and the second expansion duct 6202 is formed between the inner wall of the air guide housing 621 and the second tongue 623. Both the first expansion duct 6201 and the second expansion duct 6202 are configured to extend from one end of the air inlet to one end of the air outlet in a direction away from the central axis of the air guide shroud 62, so as to achieve an expansion of approximately 180 degrees.

[0126] For example, the first tongue 622 and the second tongue 623 are located on the upper and lower sides of the centrifugal atomizing device, and the first expansion air duct 6201 and the second expansion air duct 6202 are the upper expansion air duct and the lower expansion air duct, respectively. When the centrifugal atomizing spraying device 100 performs spraying operations, it can expand the upward and downward spraying amplitude, allowing the centrifugal atomizing spraying device 100 on the unmanned vehicle to cover a larger area in the crop height direction, thereby improving the spraying effect.

[0127] In one embodiment, reference is made to Figures 1 to 5 The outer cover 40 includes a cover mounting portion 41, through which the outer cover 40 is connected to the device body; the cover mounting portion 41 is disposed on the side of the centrifugal atomizing disk 10 near the device body. For example, the centrifugal atomizing disk 10 is located in front of the flow guiding device 20, and the portion of the outer cover 40 that connects to the device body (the cover mounting portion 41) is located behind the centrifugal atomizing disk 10, which has the following effect:

[0128] First, the centrifugal atomizing disc 10 can be removed from the front of the device without disassembling the outer cover 40, for example, by removing the bolts connecting the centrifugal atomizing disc 10 to the motor shaft. This allows for quick disassembly and replacement of the centrifugal atomizing disc 10 when it becomes clogged and requires maintenance, or when it needs to be replaced to adjust the atomization effect.

[0129] Second, the cover mounting part 41 of the outer cover 40 is closer to the fan 61. When the outer cover 40 is rotatably mounted on the flow guide device 20 and the outer cover 40 has fan blades 44, the fan blades 44 are closer to the fan 61, and the outer cover 40 can rotate around the flow guide device 20 under the blowing action of the fan 61.

[0130] Third, the cover mounting part 41 can be a mounting ring and fitted onto the outside of the flow guiding device 20. In this way, the contact area between the outer cover 40 and the flow guiding device 20 is large, the connection is more stable, the outer cover 40 has a good protective effect on the centrifugal atomizing disk 10, and is not easy to shake.

[0131] In one embodiment, reference is made to Figure 1 , Figure 7 , Figure 8 The outer cover 40 has a front opening located inside a plurality of baffles 42, and the side of the centrifugal atomizing disc 10 facing away from the flow guide device 20 is fully exposed through the front opening.

[0132] Taking the fan 61, drive unit 30, flow guide device 20, and centrifugal atomizing disc 10 arranged from back to front as an example, there are no connecting ribs or connecting plates between the front ends of several partitions 42, to prevent the droplets sprayed from the centrifugal atomizing disc 10 from settling onto the connecting ribs or connecting plates. In other words, the front opening of the outer cover 40 can reduce or avoid the settling of droplets on the outer cover 40, thus improving the user experience.

[0133] In one embodiment, the outer cover 40 includes a cover mounting portion 41, which is a mounting ring. The mounting ring is sleeved on the outside of the flow guiding device 20 and is rotatably connected to the flow guiding device 20, or fastened to it by fasteners, or integrally formed. The outer cover 40 also includes an outer ring 43, which surrounds the mounting ring and is connected to it. A plurality of spacers 42 are disposed on one side of the outer ring 43 in the axial direction and are connected to the outer ring 43.

[0134] In one embodiment, the centrifugal atomizing disc 10 includes a disc body 11 and at least one set of atomizing groups. The disc body 11 has an atomizing surface 1101, and the atomizing groups are disposed on the atomizing surface 1101. Each atomizing group includes atomizing protrusions 12 spaced apart around the center line of the disc body 11, and an atomizing flow channel 1201 is formed between adjacent atomizing protrusions 12. Exemplarily, the side of the disc body 11 close to the flow guiding device 20 is the atomizing surface 1101. The atomizing surface 1101 is arranged with three rings / three sets of atomizing groups from the inside to the outside. The atomizing protrusions 12 of the first atomizing group are strip-shaped protrusions that extend spirally from the inside to the outside. The atomizing protrusions 12 of the second atomizing group are columnar protrusions. The atomizing protrusions 12 of the third atomizing group are atomizing teeth. The liquid is dispersed multiple times after passing through multiple sets of atomizing groups, resulting in a good atomization effect.

[0135] In one embodiment, the flow guiding device 20 is used to deliver liquid to the side of the centrifugal atomizing disk 10 where the atomizing group is provided, so that the liquid can enter a plurality of atomizing channels 1201. Exemplarily, the flow guiding device 20 is a flow guiding shell and a flow guiding tube. A flow guiding cavity 22 is formed inside the flow guiding shell. The flow guiding tube is connected to the flow guiding shell and is provided with a liquid inlet 21. A liquid outlet 23 is provided on the side of the flow guiding shell near the centrifugal atomizing disk 10. The liquid inlet 21 is connected to the liquid outlet 23 through the flow guiding cavity 22. The liquid inlet 21 is used to connect to a liquid supply device (e.g., a liquid storage tank). Under the action of a pump or other force, the liquid is sent from the liquid supply device to the flow guiding cavity 22 and from the liquid outlet 23 to the centrifugal atomizing disk 10, so that the liquid enters a plurality of atomizing channels 1201.

[0136] In one embodiment, such as Figure 14 As shown, two centrifugal atomizing sprayers 100 are installed on the left and right sides of the vehicle body. The centrifugal atomizing sprayer 100 on the left side of the vehicle body is used to spray pesticide on the crop plants on the left side of the vehicle body, and the centrifugal atomizing sprayer 100 on the right side of the vehicle body is used to spray pesticide on the crop plants on the right side of the vehicle body. The orientation of the centrifugal atomizing sprayers 100 can be adjusted upward and / or downward, or towards the front and / or rear of the vehicle.

[0137] In one embodiment, such as Figure 14 As shown, the centrifugal atomizing spraying equipment 100 includes a mounting base 80, a motor that is adjustable in angle or fixedly mounted on the mounting base 80, and the mounting base 80 that is adjustable in angle or fixedly mounted on the movable platform 200.

[0138] In one embodiment, reference is made to Figure 17 , Figure 18The centrifugal atomizing disc 10 has a plurality of atomizing channels 1201 arranged around its axis of rotation. The baffle 42 includes a strip body portion 421 and an extended end portion 422 located in front of the strip body portion 421. The strip body portion 421 is located outside the region where the atomizing channels 1201 are located, and the extended end portion 422 extends forward relative to the region where the atomizing channels 1201 are located. Please continue to refer to... Figure 2 , Figure 4 The partition 42 includes a main body portion 421 and an extended end portion 422 connected to the front side of the main body portion 421. Figure 18 The horizontal dashed line at the position of the partition 42 is a non-solid structure used to divide the main body 421 and the outer extension 422 of the partition 42. (See reference) Figure 2 , Figure 4 , Figure 9 The main body 421 is located outside the area where the atomizing channel 1201 is located, and the extended end 422 extends forward relative to the area where the atomizing channel 1201 is located.

[0139] The strip body 421 is located outside the area where the atomizing channel 1201 is located. This allows at least a portion of the first type of droplets (not shown) that have left the centrifugal atomizing disk 10 along a first trajectory (not shown) to collide with the strip body 421. The first type of droplets are then dispersed and re-atomized by the strip body 421 before continuing to move outward, thus achieving re-atomization of the droplets and obtaining finer droplet particles. The first trajectory is a radial trajectory moving from the inside out; radial direction refers to the direction perpendicular to the axis of rotation.

[0140] The extended end 422 extends forward relative to the area where the atomizing channel 1201 is located, so that at least part of the second type of droplets (not shown) that leave the centrifugal atomizing disk 10 along the first trajectory (not shown) and continue to move outward, and the droplets have a larger droplet size, collide with the strip body 421 and the extended end 422. The second type of droplets are dispersed by the strip body 421 and the extended end 422 and continue to move outward, thereby realizing the re-atomization of the droplets and obtaining finer droplet particles.

[0141] The extended end 422 extends forward relative to the area where the atomizing channel 1201 is located, which allows some of the third type of droplets (not shown in the figure) that leave the centrifugal atomizing disk 10 along the second trajectory (not shown in the figure) to continue moving outward to collide with the extended end 422. The third type of droplets are dispersed by the extended end 422 and continue to move outward, thereby realizing the re-atomization of the droplets and obtaining finer droplet particles.

[0142] Understandably, under different circumstances, when the centrifugal atomizing device is working, the droplets ejected by the centrifugal atomizing disc 10 are one or more of the first type of droplets, the second type of droplets, and the third type of droplets.

[0143] In this application, the outer casing 40 includes at least one ring of baffles 42 surrounding the centrifugal atomizing disk 10. These baffles 42 not only provide protection but also re-atomize the droplets, resulting in smaller and more uniform droplet sizes and improved atomization. Furthermore, the main body 421 of the baffle 42 engages with its outer end 422 to ensure effective re-atomization of the droplets.

[0144] In one embodiment, reference is made to Figure 18 The distance by which the baffle 42 extends forward relative to the atomizing channel 1201 is the extension distance d3. In other words, the axial dimension of the outer extension end 422 is the extension distance d3 of the baffle 42. The atomizing protrusion 12 located on the outermost ring of the disc 11 is the outer ring protrusion 121. The height of the outer ring protrusion 121 is d4, which is the axial dimension between the two ends of the outer ring protrusion 121. d3 < d4. 0.05 ≤ d3 / d4 ≤ 0.4, that is, the length d3 of the outer extension end 422 of the baffle 42 is less than 40% of the channel height d4. For example, d3 is 2 mm and d4 is 6.7 mm. For another example, d3 is 5 mm and d4 is 2 cm. It is understandable that the atomizing protrusions 12 are set on the atomizing surface 1101. The sides of adjacent atomizing protrusions 12 and the atomizing surface 1101 can cooperate to define the atomizing channel 1201. The height of the atomizing channel 1201 is determined by the height of the atomizing channel 1201. The droplets are sprayed outward from the atomizing channel 1201. By controlling the ratio of the extension distance d3 of the baffle 42 to the height d4 of the atomizing channel 1201, the extension length of the baffle 42 can be controlled to a reasonable length. It is understandable that if the extension distance d3 of the baffle 42 is too small, the re-atomization effect on the droplets is limited. If the extension distance d4 of the baffle 42 is too large, it is easy to form a chain of liquid droplets on the baffle 42 and easily form large droplets.

[0145] Optionally, d3 / d4≤0.3, the length d3 of the extended end 422 of the partition 42 is less than or equal to 30% of the flow channel height d4. Optionally, 0.15≤d3 / d4, the length d3 of the extended end 422 of the partition 42 is greater than or equal to 15% of the flow channel height d4.

[0146] In one embodiment, d3 / d4 = 0.3.

[0147] In one embodiment, the distance by which the baffle 42 extends forward relative to the atomizing channel 1201 is the extension distance d3, where d3 is within a first threshold range of 0.5 mm to 1 cm. That is, 0.5 mm ≤ d3 ≤ 1 cm. Optionally, the first threshold range is 1 mm to 3 mm. Optionally, d3 is 2 mm.
