Split-type automatic sprinkler

Abstract

The invention discloses a split-type automatic sprinkler which comprises a machine case, a motor, a hollow inner pillar, a hollow outer pillar, a silicone tube and a spraying disk, wherein the inner pillar is fixed on the machine case; one end of the inner pillar is in a sealed connection with the silicone tube; the outer pillar sleeves the outer side of the other end of the inner pillar; a bearing is disposed between the outer pillar and the inner pillar; the outer pillar can be rotated relative to the inner pillar; the spraying disk is fixed on the end of the outer pillar far from the silicone tube; internal space of the spraying disk, the inner pillar and the silicone tube communicates with each other; and the motor is fixed on the machine case, and the motor drives rotation of the outer pillar by a transmission mechanism. The sprinkler disclosed by the invention has the advantages that existing design is improved; the motor and the spraying disk are set into a split structure; and pesticides pass through the silicone tube and the inner pillar and are finally sprayed out from the spraying disk, and the pesticides do not touch the motor during the course, so that the motor is protected from pesticide corrosion, and the service life of the whole device is increased.

Description

technical field [0001] The invention relates to a separate automatic spraying device, in particular to a device for protecting a motor from being corroded by sprayed pesticides. Background technique [0002] With the development of science and technology, automation technology has gradually penetrated into the field of modern agriculture and forestry technology, and has greatly improved people's productivity. Among them, the automatic spraying device is a kind of equipment used to spray pesticides on crops, vegetables, fruit trees, forest trees, etc. It mainly uses a pump (or other power mechanism) to draw pesticides to the spray plate through a silicone tube, spray The disc is also rotated by a motor, so that the pesticide is sprayed more evenly on the crops. [0003] However, the existing automatic spraying device has the following problems: the spray plate is directly connected to the rotor of the motor, and the silicone tube communicates with the interior of the spray p...

AI Technical Summary

Problems solved by technology

When the pesticide passes through the silicone tube to the inner shaft hole of the motor, and then flows into the nozzle, it also comes into contact with the pesticide at the place where the nozzle contacts the motor, and the pesticide is corrosive, and the life of the motor will be affected after being corroded by the pesticide, thus affecting the entire device life span
