Description

Technical Field

[0001] The utility model belongs to the technical field of spraying operations, and particularly relates to an atomizing spray disc for an unmanned aerial vehicle with double supercharging. Background Art

[0002] The spray disc of a plant protection unmanned aerial vehicle is an accessory for an unmanned aerial vehicle designed specifically for precision agriculture, which has the characteristics of optimizing the spraying range and atomizing effect. It can effectively improve the coverage uniformity and utilization rate of pesticides, and help agricultural production achieve efficient and environmentally friendly plant protection operations.

[0003] However, although the existing spray discs can meet the basic requirements, there is still room for improvement. The insufficient spraying pressure limits the spraying range, making it difficult for pesticides to evenly cover the target area. Summary of the Utility Model

[0004] Based on the above problems in the prior art, the utility model provides an atomizing spray disc for an unmanned aerial vehicle with double supercharging, which includes a disc body. Atomizing teeth are arranged on the peripheral side of the disc body. The disc body is further provided with:

[0005] A liquid guide member, which is used to guide the water in the disc body to the atomizing teeth by centrifugal force when the disc body rotates;

[0006] An air guide member, which is connected to the liquid guide member and is used to drive air to flow into the liquid guide member at an accelerated speed when the disc body rotates.

[0007] Wherein, the air guide member is an air-gathering channel, and the air-gathering channel is formed by being separated by an arc-shaped partition plate arranged on the upper surface of the disc body. The air-gathering channels are arranged in a spiral divergent shape. The end of the air-gathering channel close to the center of the disc body is the inner end and is connected to the liquid guide member.

[0008] Wherein, the liquid guide member is arranged on the lower surface of the disc body. A liquid storage cavity is arranged at the center of the disc body. The inner end of the air-gathering channel extends to the outside of the liquid storage cavity and is not connected to the liquid storage cavity. The bottom of the inner end of the air-gathering channel is connected to the liquid guide member.

[0009] Wherein, the liquid guide member is a centrifugal water channel, and the centrifugal water channel is formed by being separated by turbine blades arranged on the lower surface of the disc body. The centrifugal water channels are arranged in a spiral divergent shape opposite to the spiral direction of the air-gathering channels, and the centrifugal water channels are connected to the air-gathering channels one by one.

[0010] Wherein, an upper cover is fixedly installed above the disc body. The upper cover covers all the arc-shaped partition plates and forms an air-gathering channel with only two open ends. The outer end opening of the air-gathering channel extends to the side surface of the disc body, and the inner end opening of the air-gathering channel is connected to the centrifugal water channel.

[0011] Wherein, a bottom cover is fixedly installed below the disk body, the bottom cover covers all the turbine blades and blocks the lower parts of all the centrifugal water channels and the lower part of the liquid storage cavity. The outer end opening of the centrifugal water channel faces the atomizing teeth, the inner end opening of the centrifugal water channel communicates with the liquid storage cavity, and the top of the inner end communicates with the air gathering channel.

[0012] Wherein, at the center of the upper surface of the bottom cover, there is an installation post for driving connection with the driving motor. The upper surface of the bottom cover is also provided with positioning grooves in one-to-one correspondence and inlay with the turbine blades. At the outer end outlet of the centrifugal water channel corresponding to the upper surface of the bottom cover, there are also several diamond-shaped partition blocks.

[0013] Wherein, several guide water grooves with triangular cross-sections are arranged on the circumferential side of the lower surface of the disk body. The guide water grooves correspond to the atomizing teeth one by one. The deepest part of each guide water groove at one end close to the corresponding atomizing tooth faces the atomizing tooth along the water flow direction.

[0014] Wherein, several leveling holes for adjusting the weights on each side of the atomizing spray disk are arranged on the upper surface of the disk body, and the leveling holes are arranged in a circumferentially uniform manner with the center of the disk body as the center.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. An air guiding member communicating with the liquid guiding member is arranged on the disk body. During the spraying operation, the high-speed rotation of the spray disk will suck in the surrounding air through the air guiding member and accelerate and pressurize it. Then, the high-speed and high-pressure air flow enters the liquid guiding member, and the flow rate and pressure of the liquid in the liquid guiding member are increased. The spraying pressure is increased by the dual pressurization methods of rotary centrifugation and air flow pressurization, which can not only reduce the power of the driving motor, but also increase the spraying range, and at the same time form a better atomization effect.

[0017] 2. Leveling holes are arranged on the disk body. By adding weights into the leveling holes, the weights in all directions of the disk body and the entire spray disk can be slightly adjusted, making up for the deficiency of uneven weights on each side of the spray disk caused by low production accuracy, and improving the balance performance and stability of the rotation of the spray disk.

The guiding water grooves 11 and the atomizing teeth 12 are in one - to - one correspondence. The deepest part of each guiding water groove 11 at one end close to the corresponding atomizing tooth 12 faces the atomizing tooth 12 along the water flow direction. A liquid storage cavity 13 is arranged at the center of the disc body 1. A centrifugal water channel 14 serving as a liquid guiding member and a gas gathering channel 15 serving as a gas guiding member are further arranged on the disc body 1.

[0028] The centrifugal water channels 14 are formed by being separated by the turbine blades 16 provided on the lower surface of the disk body 1, and the centrifugal water channels 14 are arranged in a spiral divergent shape; the bottom cover 3 is fixedly installed on the lower surface of the disk body 1 through bolts, and the bottom cover 3 covers all the turbine blades 16 and blocks the lower parts of all the centrifugal water channels 14 and the lower part of the liquid storage cavity 13, forming centrifugal water channels 14 with three openings. The outer end opening of the centrifugal water channels 14 faces the atomizing teeth 12, the inner end opening of the centrifugal water channels 14 communicates with the liquid storage cavity 13 and the top of the inner end communicates with the air gathering channel 15, and the centrifugal water channels 14 and the air gathering channel 15 communicate with each other one by one. At the same time, an installation post 31 for transmission connection with the driving motor is provided at the center of the upper surface of the bottom cover 3. The installation post 31 passes through the liquid storage cavity 13 and extends above the entire atomizing disk. A positioning hole is provided on the installation post 31, and the entire atomizing disk is installed on the rotating shaft of the driving motor through the positioning hole, so as to realize driving the atomizing disk to rotate at a high speed by the driving motor; a positioning groove 32 corresponding to the turbine blade 16 one by one is also provided on the upper surface of the bottom cover 3. The turbine blade 16 is embedded in the positioning groove 32, which can improve the relative fixing ability between the bottom cover 3 and the disk body 1 and prevent the bottom cover 3 and the disk body 1 from being misaligned with each other; a plurality of diamond-shaped partition blocks 33 are also provided on the upper surface of the bottom cover 3 at the outer end outlet corresponding to the centrifugal water channels 14. The water flow can be pre-divided by the diamond-shaped partition blocks 33 to improve the splitting and atomizing effect of the water flow. The setting of the liquid guiding member can realize guiding the water in the liquid storage cavity 13 of the disk body 1 to the atomizing teeth 12 for cutting and atomizing by using centrifugal force when the disk body 1 rotates;

[0029] The air gathering channel 15 is formed by being separated by the arc-shaped partition plate 17 provided on the upper surface of the disk body 1. The air gathering channel 15 is also arranged in a spiral divergent shape and the spiral direction is opposite to that of the centrifugal water channels 14. The end of the air gathering channel 15 close to the center of the disk body 1 is the inner end. The inner end of the air gathering channel 15 extends to the outside of the liquid storage cavity 13 and does not communicate with the liquid storage cavity 13; the upper cover 2 is fixedly installed above the disk body 1 through bolts. The upper cover 2 covers all the arc-shaped partition plates 17 and forms an air gathering channel 15 with only two openings. The outer end opening of the air gathering channel 15 extends to the side surface of the disk body 1. An opening is provided at the bottom of the inner end of the air gathering channel 15 and communicates with the centrifugal water channels 14. The setting of the air guiding member can realize driving the air to flow into the liquid guiding member at an accelerated speed when the disk body 1 rotates, and then improving the atomizing pressure of the atomizing disk through the air with increased speed and pressure, and then improving the spraying range and atomizing degree.

[0030] As a preferred embodiment, the disc body 1 is provided with a leveling hole 18 for adjusting the weight of each side of the atomizing spray disc on the upper surface of the inner end of each arc-shaped partition 17, and a total of twelve leveling holes 18 are provided. The twelve leveling holes 18 are evenly arranged in a circle with the center of the disc body 1 as the center. When the weight of the atomizing spray disc is not parallel, counterweights can be added to the leveling holes 18 as needed, such as squeezing in glue, or adding other weights first and then fixing them with glue, etc. The weight of each side of the spray disc can be adjusted by the later added counterweights to improve the parallelism of the spray disc and the smoothness of high-speed rotation.

[0031] The atomizing spray disc provided in this embodiment is installed on a drone for use. The spray disc is connected to a driving motor fixedly installed on the drone through a mounting column 31, and then the infusion structure on the drone is connected to the liquid storage chamber 13, so that liquid can be replenished into the liquid storage chamber 13 through the infusion structure.

[0032] When spraying is required, the driving motor drives the spray disc to rotate at high speed. When the spray disc reaches the set rotation speed, the infusion structure adds the corresponding liquid into the liquid storage chamber 13. The high-speed rotation of the spray disc will throw the liquid in the liquid storage chamber 13 outward through centrifugal force, so that the liquid passes through the centrifugal waterway 14 and hits the guide water tank 11, and then flows to the atomizing teeth 12, and is cut into water mist by the atomizing teeth 12. The water mist continues to be thrown outward under the action of centrifugal force to form a spray effect. During the high-speed rotation of the spray disc, the spray disc will inhale and compress the surrounding air through the cooperation of the arc partition 17 and the air gathering channel 15, and then transport the compressed air to the centrifugal waterway 14. The compressed air increases the air pressure in the centrifugal waterway 14, accelerates the water flow rate, and forms a better atomization effect and a larger spraying range.

[0033] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
