Problems solved by technology

However, since this patent does not use airflow-assisted spraying, the anti-drift performance of spray droplets above the crop canopy is poor; the diffusion performance of spray droplets in the middle and lower layers of crops is poor
And because the nozzles arranged on the bracket mechanism and the boom use the same droplet diameter distribution, their anti-drift performance and penetration performance cannot be unified, making it difficult to have the best deposition performance

Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the patent of the present invention is further described. A compound application device suitable for high canopy density crops according to the present invention, such as figure 1 , 2, 3, 4 shown. A compound spraying device suitable for crops with high canopy density, comprising a spray bar type spraying system, a mist spraying system, a lifting adjustment system and a support frame of the spraying system. The spray bar spraying system realizes the spraying of liquid medicine on the upper part of the crops with high canopy density through the anti-drift nozzle installed on the spray bar; the mist spraying system uses the high-speed airflow generated by the spray machine The medicinal liquid is atomized and transported to the rows of crops to realize the diffusion and deposition of droplets in the middle and lower parts of crops with high canopy density; the support frame of the spraying system fixes and supports the spra...

Abstract

The invention relates to a compound spraying device and method suitable for crops with high canopy density, comprising a spray rod type spraying system, a mist spraying system, a lifting adjustment system and a support frame of the spraying system. The boom-type spraying system realizes the spraying mode of spraying liquid with large droplet diameter and is not easy to drift in the upper part of the high canopy density crops; the mist spraying system realizes the Ultra-small droplet diameter, easy to spread evenly mist liquid spraying mode. The support frame of the spraying system fixes and supports the spraying boom and mist spraying systems; the lifting adjustment system adjusts the spraying height of the spraying boom and mist spraying to meet the spraying needs of crops of different heights. While ensuring the uniform deposition effect of the medicinal liquid, the invention reduces the power consumption of the spraying machine and the risk of droplet drift, improves the effective utilization rate of the medicinal liquid, enhances the effect of preventing and controlling crop diseases and insect pests, and reduces environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of plant protection machinery, and relates to a compound spraying device and method suitable for crops with high canopy density, especially suitable for the control of diseases and insect pests or defoliants when high canopy density canopies are formed in the middle and late stages of crops such as cotton and corn Wait for the medicine to be sprayed. [0002] technical background [0003] Common boom spraying is mostly used in field crop pest control. Boom spraying is more effective in the control of plant diseases and insect pests in the seedling stage of crops. However, modern agronomy requires reasonable close planting to increase yield, but close planting crops grow to the middle and late stages, forming a canopy with high canopy density. [0004] When the crops grow to the middle and late stages to form a canopy with high canopy density, if a single boom-type spraying machine is still used, due to bein...
