Suspension type spraying operation system and control method thereof

Abstract

The invention discloses a suspension type spraying operation system. The system comprises a primary power chassis, an assistant power chassis and a spraying operation module, wherein the primary power chassis and the assistant power chassis cooperate with each other for advance, and the spraying operation module is suspended between the primary power chassis and the assistant power chassis during the normal work of the system and can conduct spraying operation on field. A material liquid supply control module(s) capable of supplying materials required by the spraying operation module and power module(s) used for supplying power energy are arranged on the primary power chassis and/or the assistant power chassis, and a main control module controlling the work of the primary power chassis, the assistant power chassis and all the modules in an electric connection mode is arranged on the primary power chassis or the assistant power chassis. According to the suspension type spraying operation system, the primary power chassis and the assistant power chassis run on corresponding ridges respectively, and damage to the field cannot be caused; the spraying operation module is suspended above the position between the primary power chassis and the assistant power chassis, the spraying operation module itself has power, spraying operation module cannot happen, and the spraying precision is improve.

Description

technical field [0001] The present application relates to the field of spraying technical equipment for field spraying operations, in particular to a suspended spraying operation system and a control method thereof. Background technique [0002] The spraying technology of pesticides and chemical fertilizers in my country is relatively low, and the spraying machines are mainly manual and small electric sprayers, and tractor-mounted plant protection machines account for about 0.57%. Ground machinery has serious damage to crops and field ground; manual backpack spraying machinery has low operating efficiency and wastes manpower and material resources. When spraying pesticides by conventional methods, only 25% to 50% of the pesticides are sprayed on the crops, and most of them are lost in the form of volatilization and drift, and the utilization rate of pesticides is low. According to statistics, the utilization rate of pesticides on field crops in my country is about 30%, whic...

AI Technical Summary

Problems solved by technology

However, unmanned aerial spraying operations are still expensive and dangerous for ordinary farmers

In addition, the small payload and short operating life of unmanned aerial vehicles are also key issues restricting its rapid development.

[0007] In order to overcome the above-mentioned limitations, patents CN104002974A, CN104512551A, CN105794758A, CN103754368A, CN101518222A, CN104738012A etc. disclose several spraying operation modes combining ground and air. There are common problems such as difficult control of the air part and inaccurate synchronization

In particular, the spraying operation method using hydrogen balloons or helium balloons to provide lift, in addition to the above problems, there are also problems such as large wind resistance, safety hazards (hydrogen is explosive), high cost (helium recovery is inconvenient and difficult to reuse), etc.
