Self-adaptive orchard sprayer

Abstract

A self-adaptive orchard sprayer comprises a traction chassis, wherein a pesticide application device and a plurality of movable ultrasonic detection devices are arranged at the front end above the traction chassis. Each ultrasonic detection device mainly comprises an ultrasonic sensor and a vertical moving device, and a detection signal of the ultrasonic sensor is output and connected to an embedded control platform. The pesticide application device mainly comprises a pesticide spraying device and a stepping motor rotation control device, wherein the pesticide spraying device are provided with electric ball valves, flow sensors, pressure sensors and solenoid valves, and detection and control signals of the electric ball valves, the flow sensors, the pressure sensors and the solenoid valves are connected to the embedded control platform which integrates signals of the sensors to control opening of the electric ball valves and actions of the solenoid valves. By means of the self-adaptive orchard sprayer, tree form information of control targets in an orchard can be collected automatically; according to the information, the ultrasonic sensors can be distributed automatically, and rotating angles of an air bellow are regulated automatically, or rotating angles of the air bellow can be regulated manually according to actual needs. Therefore, pesticide application efficiency is increased, pollution to the environment and personal injury to operators caused by pesticide application are reduced.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection machinery, and relates to a sprayer, in particular to an adaptive orchard sprayer. Background technique [0002] There are many diseases and insect pests on fruit trees in orchards. According to different needs, pesticides are sprayed many times, and the number of sprays is as many as 8-16 times a year. However, at present, my country's pesticide application technology and automatic pesticide application machines are seriously backward. Only a small part of the sprayed pesticides can adhere to the targets to be controlled, and the utilization rate of pesticides is extremely low. According to statistics, only 15%-20% of the pesticides attached to fruit trees , more than 80% of the pesticides are lost to the surrounding environment, causing a serious waste of pesticides and environmental pollution while posing a great threat to human and animal safety. The existing air-to-target sprayers...

Problems solved by technology

However, at present, my country's pesticide application technology and automatic pesticide application machines are seriously backward. Only a small part of the sprayed pesticides can adhere to the targets to be controlled, and the utilization rate of pesticides is extremely low. According to statistics, only 15%-20% of the pesticides attached to fruit trees , more than 80% of pesticides are lost to the surrounding environment, causing serious pesticide waste and environmental pollution, and at the same time posing a great threat to human and animal safety

The existing air-to-target sprayers in my country mainly collect information based on corresponding sensors. The spray range of the sprayer is controlled by the air speed and the opening and closing of the corresponding nozzles, which cannot adapt to the target tree shape. Sending sprayer (CN201310007484.8), self-propelled orchard automatic target sprayer and its spraying method (CN201310538956.2), a self-propelled automatic target sprayer (CN201210120687.3), can not be based on orchard fruit trees The spraying method is automatically adjusted to the height and row spacing. Before the spraying, the rotation angle of the bellows and the spraying range must be manually adjusted by manpower. During the spraying process, the adjustment must be stopped before the operation can be completed. The degree of automation is low, and the structure must be controlled by Its special running device connection has poor versatility
