Conic mist centrifugal atomizing disc and assembly

Abstract

The invention discloses a conic mist centrifugal atomizing disc and assembly. The conic mist centrifugal atomizing disc and assembly comprise a conic disc, an anti-overflowing ring, an embedded nut and a shaft sleeve. A sinking flow division cavity is formed in the center of the conic disc, a vertical ring extending upwards is arranged on the upper portion of the conic disc, and an embedment holeis formed in the center of the bottom of the flow division cavity. The anti-overflowing ring is fixedly connected to the vertical ring. The embedded nut is installed in the embedment hole. One end ofthe shaft sleeve is located in the embedment hole and fixedly connected with the conic disc through the embedded nut, and the other end of the shaft sleeve is located in the vertical ring and used forbeing connected with a power output shaft. A flow division plane is formed on the bottom face of the flow division cavity, and flow division barriers and flow division channels distributed evenly inthe circumferential direction and spaced apart are arranged on the flow division plane. The conic disc is opened downwards and provided with a cone angle, sharp teeth arrayed in the circumferential direction are arranged in the conic disc, and a groove opened downwards is formed between every two adjacent sharp teeth. Each sprayed mist flow can be tapered, settling velocity is increased, the mistflows have certain targeting performance, and floating is reduced; and due to rotary self-tightening, the disc and assembly are more convenient to detach and install, the number of parts is reduced, and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of plant protection machinery and relates to a spray device, in particular to a conical fog centrifugal atomizing disc and components. Background technique [0002] Centrifugal atomization technology has been widely used in the field of low-volume spraying, especially in aerial plant protection, due to its characteristics of good atomization uniformity, droplet spectrum width, adjustable particle size, and unfavorable clogging. The main defect of the existing centrifugal atomization technology is that the direction of the mist flow is ejected along the horizontal direction. Compared with the hydraulic atomizer, the mist droplets lack the initial velocity in the direction of settlement, the targeting is poor, the spray width is easy to change, and the mist drift is relatively slow. difficult to control. At present, the application on the plant protection unmanned aircraft is mainly through the coupling of the fog flow...

Problems solved by technology

Although it can be seen from the drawings that the channel openings are oriented below the horizontal direction, there is no reasonable diversion structure inside the blisk, and the liquid medicine entering the blisk is difficult to distribute evenly to each channel due to the interference of the column, and the channel scale is too large , when the liquid medicine entering the channel is concentrated and slips towards the stressed side during rotation, the kinetic energy of the blisk cannot be fully transferred to all the liquid medicine through the constraining surface, and the excess part overflows randomly, making it difficult to control the liquid flow to form evenly distributed liquid filaments and liquid drop

[0004] The problems existing in the practical application of the above-mentioned technologies can be summarized as follows: 1) Although the addition of the atomization disk body to change the wind field structure can increase the droplet settling velocity, it will have a negative impact on the uniformity of the atomization; 2) simply changing the fog The orientation of the opening of the atomizer disc can not improve the atomization performance, and the unreasonable auxiliary structure will reduce the atomization effect, so further improvement and perfection are needed
