Description

Technical Field

[0001] This utility model belongs to the field of drone accessories, and in particular relates to an atomizing spray disc with multi-faceted cutting columns. Background Technology

[0002] The spraying device used by agricultural drones consists of components such as a drive motor and a spray disc. The spray disc is located at the end of the output shaft of the drive motor and is fixed by a spray disc locking device. Liquid enters the middle of the spray disc through a pipe, and the drive motor outputs power to make the spray disc rotate at high speed, thereby atomizing the liquid.

[0003] For example, utility model patent CN217730779U provides a centrifugal atomizing omnidirectional spraying device for drones, which includes a rotating atomizing device with several atomizing columns evenly arranged around its periphery. These atomizing columns are cutting columns used to collide with and cut the high-speed flowing water. However, these cutting columns are cylindrical with relatively smooth surfaces, resulting in insufficient cutting ability and poor cutting atomization effect, thus affecting the spraying effect. Summary of the Invention

[0004] In view of the above-mentioned problems in the existing technology, the present invention provides an atomizing spray disc with multi-faceted cutting columns, including a cutting disc, wherein the cutting disc is provided with multiple cutting columns arranged circumferentially for dividing the liquid flow, and the cutting columns are multi-faceted columns.

[0005] The cutting disc is circular, with a liquid inlet at its center, and the cutting columns are evenly spaced on the outer side of the cutting disc.

[0006] The cutting columns are arranged in N layers along the radial direction of the cutting disk, where N is an integer greater than or equal to 1, and the cutting columns in the same layer are equidistant from the center of the cutting disk.

[0007] Among them, the cutting columns in the same layer are of equal height, and the cutting column closer to the center of the cutting disk is shorter than the cutting column farther from the center of the cutting disk.

[0008] The cutting prism is a regular polygonal prism, which includes one or more of the following: triangular prism, square prism, pentagonal prism, hexagonal prism, heptagonal prism, and octagonal prism, preferably a regular square prism.

[0009] The atomizing spray disc with multi-faceted cutting column further includes a guide plate, which is fixedly installed on one side of the cutting disc. The guide plate is provided with spiral guide wings protruding towards the cutting disc, and spiral guide grooves are formed between adjacent spiral guide wings to guide the liquid flow direction. The cutting column extends towards the guide plate, and one edge of the cutting column is directly facing the liquid flow direction, or one side of the cutting column is perpendicular to the liquid flow direction.

[0010] The cutting disc is composed of two mutually symmetrical half-discs joined together.

[0011] When the half discs are spliced ​​together to form a cutting disc, the side that is close to each other is the splicing surface. One end of the splicing surface is provided with a positioning protrusion, and the other end of the splicing surface is provided with a positioning groove. The positioning protrusion and the positioning groove are matched and inserted with an interference fit.

[0012] The half-disc is also fixedly provided with a splicing seat, which is provided with a connecting hole. The two half-discs are fixedly spliced ​​by passing through the corresponding coaxial connecting holes of the two half-discs simultaneously. The connecting component includes a bolt and a pin.

[0013] The beneficial effects of this invention are as follows: the shape of the cutting column has been adjusted, and the traditional cylindrical cutting column has been optimized into a prismatic cutting column. The collision and cutting capabilities of the cutting column are improved by the prism's edges, thereby improving the atomization effect and atomizing the water flow into smaller droplets, achieving a more uniform atomization spraying effect.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1: Integrated atomizing spray disc.

[0026] As attached Figure 1-6 The atomizing spray disc shown includes a cutting disc 1 and a guide disc 2. The cutting disc 1 is circular, with a liquid inlet 3 at its center. Two layers of cutting columns 4, integrally formed on the outer side of the cutting disc 1, are used to divide the liquid flow. The cutting columns 4 are regular square prisms. In practical applications, depending on actual needs such as the liquid flow direction, the number of guide grooves on the guide disc, and the required atomization effect, one or more combinations of polyprisms such as regular triangular prisms, regular pentagonal prisms, regular hexagonal prisms, regular heptagonal prisms, and regular octagonal prisms can be selected as the cutting columns 4. The fewer the number of edges, the stronger the cutting ability. The two layers of cutting columns 4 are arranged radially along the cutting disc 1. The distance from the cutting columns 4 in the same layer to the center of the cutting disc 1 is equal, and the height of the cutting columns 4 within the layer is equal, forming an outer layer of cutting columns 4 and an inner layer of cutting columns 4. The inner layer of cutting columns 4 is closer to the center of the cutting disc 1 than the outer layer of cutting columns 4. The outer cutting columns 4, which are shorter than the outermost cutting columns 4 and located away from the center of the cutting disk 1, are arranged evenly along the circumference of the cutting disk 1. Each layer of cutting columns 4 contains multiple cutting columns 4. The multiple cutting columns 4 within the layer are evenly spaced along the circumference of the cutting disk 1. The guide plate 2 is fixedly installed on one side of the cutting disk 1 and forms a temporary liquid storage space with the cutting disk 1. The liquid inlet 3 of the cutting disk 1 is connected to the liquid storage space. The guide plate 2 is provided with spiral guide wings 5 ​​protruding towards the cutting disk 1. Spiral guide grooves 6 are formed between adjacent spiral guide wings 5 ​​to guide the liquid flow direction. The spiral guide grooves 6 are connected to the liquid storage space from the side. When the atomizing spray disk rotates at high speed, centrifugal force is used to throw the liquid in the liquid storage space towards the spiral guide grooves 6, and the liquid is sprayed outward through the guidance of the spiral guide grooves 6. The cutting columns 4 extend towards the guide plate 2. One edge of the cutting column 4 faces the liquid flow direction, so that the high-speed sprayed liquid can collide with the edge and be cut into tiny droplets, thereby achieving atomization and improving the atomization spraying effect. Because the height of the inner cutting column 4 is less than the height of the outer cutting column 4 which is farther from the center of the cutting disk 1, the liquid in the flow that is close to the cutting disk 1 will pass through the inner cutting column 4 and the outer cutting column 4 in turn and be cut and atomized twice, forming smaller droplets. Smaller droplets can drift to a farther area and the spraying effect is more uniform. On the other hand, the liquid that is relatively far away from the cutting disk 1 will only pass through the outer cutting column 4 and be cut and atomized once, forming droplets with a larger diameter, which can be concentrated to spray the nearby area. The final spraying effect can be further improved by mixing and spraying droplets of two different diameters.

[0027] Example 2: Interlocking atomizing spray disc.

[0028] The difference between this embodiment and Embodiment 1 lies in the structure of the cutting disc 1, as shown in the attached figure. Figure 7-10 The diagram shows an atomizing spray disc with a multi-faceted cutting column. The cutting disc 1 is composed of two mutually symmetrical half-discs 7 joined together. The sides of the half-discs 7 that are close to each other when joined together form the joining surface. One end of the joining surface is provided with an arc-shaped positioning protrusion 8, and the other end is provided with a positioning groove 9. The positioning protrusion 8 and the positioning groove 9 are matched and inserted into each other with an interference fit. The two half-discs 7 are initially fixed by inserting the positioning protrusion 8 into the positioning groove 9. Two splicing seats 10 are also fixedly installed on the half-discs 7. The two splicing seats 10 are located at opposite ends of the joining surface. Each splicing seat 10 is provided with two connecting holes 11. The two half-discs 7 are fixedly joined together by bolts, which act as connectors, passing through the corresponding coaxial connecting holes 11 of the two half-discs 7 simultaneously, thus forming a complete cutting disc 1.

[0029] The cutting disc 1 provided in this embodiment is a spliced ​​cutting disc 1, which is composed of two smaller half discs 7 spliced ​​together. Although the structural strength is relatively reduced, it is more flexible and convenient in terms of production, transportation and storage due to its smaller size, and can adapt to more different actual environments. At the same time, due to its smaller size, the required production line and production mold can be reduced accordingly, which can reduce production costs.

[0030] The above-described embodiments only illustrate two implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
