Precise spraying device based on plant morphology

Abstract

The invention discloses a precise spraying device based on plant morphology. The bottom surface of one side of a rightward inverted L-shaped bracket is fixed on a base; a motor is mounted on the top surface of one side of the rightward inverted L-shaped bracket; an inertial navigation assembly and an industrial camera are mounted on the other side of the rightward inverted L-shaped bracket; a screw rod is mounted on the inner side surface of one side of the rightward inverted L-shaped bracket and is connected with a motor shaft; one end of the bracket and the screw rod form a screw pair; the other end of the bracket is connected with an electromagnetic valve; a water pipe wound with an electric heating belt set is mounted on the lower surface of the bracket; one end of the water pipe is connected with a nozzle via the electromagnetic valve; a single-chip controller is electrically connected with one end of a relay set, the industrial camera, the inertial navigation assembly and a temperature sensor respectively and is electrically connected with the motor via a motor controller; the other end of the relay set is electrically connected with the electromagnetic valve and the electric heating belt set. The precise spraying device is capable of obtaining the plant morphology by photographing the plant and carrying out image sequence processing on the plant, so that an effective spraying method is obtained; the deposition rate of spray droplets is increased; the temperature of the spray droplets before spraying can be accurately controlled by heating in a grouping manner; the penetration performance of the spray droplets can be improved.

Description

technical field [0001] The invention relates to a precision spraying device, in particular to a precision spraying device based on plant shape in the field of agricultural technical engineering. Background technique [0002] Most of the existing precision spraying devices only consider the presence or absence of plants, and do not use plant height as a control variable for spraying. In the case of a certain spray angle of the nozzle, the coverage of the spray droplets is different for plants of different heights, which will lead to the waste of the amount of medicine or the spray droplets cannot completely cover the plants, reducing the deposition rate of the spray droplets. China Invention Application No. 201510062346.9 discloses an invention titled "Nozzle Switching Device Based on Steering Gear Drive", which includes a signal acquisition and processing unit, a solenoid valve, a nozzle, a multi-nozzle body, a steering gear drive unit, and a fixed support unit. It adopts t...

Problems solved by technology

It controls the spraying through the presence and size of plants. Although this method achieves the purpose of saving the amount of medicine, the droplet deposition rate is not high when dealing with plants of different heights, which will still cause waste of medicine.
