Mechanical-airflow combination disturbance chemical application system

Abstract

The invention discloses a mechanical-airflow combination disturbance chemical application system which comprises a chemical liquid box, a filter, a chemical liquid pump and a spray rod. The chemical liquid box, the filter, the chemical liquid pump and the spray rod are connected in sequence through pipes. A spray head A, a spray head B A, a spray head C, a spray head D and a spray head E are installed on the spray rod. A connecting rod device for pushing a crop canopy open is arranged in the front of the spray rod, and the connecting rod device is used for pushing the crop canopy open to generate cracks. An air duct A, an air duct B, an air duct C, an air duct D and an air duct E are installed on the spray head B A, the spray head C, the spray head D and the spray head E in sequence. The air duct A, the air duct B, the air duct C, the air duct D and the air duct E are used for injecting airflow downwards or slantly downwards. The mechanical-airflow combination disturbance chemical application system can be applied to a spray rod type spraying machine, deposition distribution uniformity of fogdrops in the dense crop canopy of rice and wheat and the like can be improved effectively, and uniform chemical application to the whole plant is achieved.

Description

technical field [0001] The invention relates to a mechanical-airflow combined disturbance pesticide application system, which belongs to the field of plant protection machinery. Background technique [0002] With the large-scale transfer of rural labor force to cities and the rapid expansion of agricultural operations, large and medium-sized mechanized pesticide application equipment will soon become the mainstream. Promote and test in some large and medium-sized farms. However, the boom sprayer sprays downwards from the top of the crop canopy. Due to the dense canopy of crops such as rice and wheat, most of the droplets are intercepted by the dense upper canopy of the crops, and the amount of liquid medicine deposited in the middle and lower canopies is small. The control effect on diseases and insect pests in the middle and lower part of the crop canopy is poor. [0003] In the prior art, the pesticide application methods that can increase the amount of pesticide solutio...

Problems solved by technology

[0005] Both of these two patents use the air delivery system for spraying. The air delivery system relies on the airflow to increase the velocity of the droplets and increase the disturbance of the canopy, which can significantly enhance the penetration of the droplets. However, the spraying effect is affected by the characteristics of the airflow and The characteristics of the canopy have a great influence. For the dense canopy, the droplet penetration ability is insufficient, and the amount of liquid medicine deposition in the lower canopy is still very small
