Magnetic suspension high-speed impact atomizing nozzle

Abstract

The invention discloses a magnetic suspension high-speed impact atomizing nozzle, and relates to the technical field of agricultural equipment. The magnetic suspension high-speed impact atomizing nozzle comprises a liquid inlet pipe, an acceleration pipeline, a connecting pipe and a return pipe; and a liquid outlet side wall hole in the acceleration pipeline communicates with the connecting pipe, and liquid flows into the acceleration pipeline through the liquid inlet pipe, is accelerated in the acceleration pipeline, flows into the connecting pipe and is sprayed out through a liquid outlet head. Liquid medicine is impacted and accelerated through magnetic suspension metal balls moving at a high speed, so that the speed of the liquid medicine in a centrifugal impact pipeline is increased, and after a rotating speed threshold value is reached, the liquid medicine enters a Laval pipe through a flow guide pipe after a knob switch is turned on, is subjected to secondary acceleration and then is lapped out through liquid outlet holes in the liquid outlet head. Compared with a common mode that a centrifugal atomization disc is driven by a motor to conduct centrifugal atomization, the acceleration mode provided by the device has the advantages of being simple in structure, low in resistance loss in the acceleration process and high in atomization efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a magnetic levitation high-speed impact atomizing nozzle. Background technique [0002] At present, with the transfer of land and the gradual scale of agricultural land production, in order to improve agricultural productivity and reduce the cost of agricultural production, there is an increasing demand for drones to spray pesticides and other operations. The nozzles of existing plant protection drones generally use centrifugal nozzles. The nozzles usually use centrifugal motors to provide rated voltage and output rated speed, and there are grooves on the centrifugal disc, and the liquid in the groove is transferred to the atomizer. The edge opening of the disc, so that the atomizing nozzle can achieve the expected atomization effect. [0003] When the drone is spraying, the motor drives the centrifugal disc of the centrifugal nozzle to rotate at a high speed to g...

AI Technical Summary

Problems solved by technology

However, the motor drives the centrifugal disc to rotate because of the loss caused by the resistance in the process of mechanical transmission, which reduces the maximum speed threshold that the centrifugal atomizing disc can achieve, which results in a limited ejection speed of the liquid medicine sprayed by the centrifugal nozzle and the centrifugal The atomizing disc drains through grooves, and the liquid in each groove in the rotation cannot guarantee a relatively balanced flow rate, which makes the atomizing surface of the atomizing disc uneven in actual use, and the atomization efficiency is relatively low
