Sprayer

Abstract

The invention discloses a sprayer which comprises a trolley with walking wheels, a liquor box, a gasoline engine, a water pump, a spray nozzle and a spray boom; the liquor box, the gasoline engine and the water pump are installed on the underframe of the trolley, and the spray boom is fixed on the upright post in front of the trolley; an outlet of the liquor box is communicated with an inlet pipeline of the water pump, and an outlet of the water pump is communicated with a pipeline of the spraying boom; the other end of the spraying boom is connected with the spray nozzle, and a power wheel of the water pump is connected with a driving wheel strap of the gasoline engine; the spray boom which is arranged below the spray nozzle is connected with a recovery device which is used for recovering liquor, and the recovery device comprises an open container, a reflux hole arranged at the bottom thereof, a filtering net arranged above the reflux hole and a pipeline which is below the reflux hole and connected with an inlet of the liquor box. The sprayer recovers and reuses fog drops which drift away from an aiming target, increases the utilization rate of pesticide, and reduces the harm of the pesticide to personal safety and environmental pollution. Meanwhile, the sprayer can be operated under adverse weather conditions such as wind and the like without being influenced, thereby enhancing working efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection machinery, and relates to a sprayer, in particular to a sprayer with a liquid medicine recovery device. Background technique [0002] Although many studies are dedicated to finding new plant protection methods to control pests and diseases, the use of plant protection machinery to spray chemical pesticides is currently the most effective means of control. Domestically, in the control of diseases and insect pests of such fruits as kiwifruit and grapes, since the nozzle of the sprayer is often sprayed upwards, the large droplets and the droplets that did not hit the target fall to the ground under the action of gravity, resulting in a large amount of liquid medicine. waste, but also a great pollution to the environment. Studies have shown that a large amount of liquid medicine (more than 70%) is not deposited on the target, and the loss of this part of liquid medicine to the environment...

Problems solved by technology

Domestically, in the control of diseases and insect pests of such fruits as kiwifruit and grapes, since the nozzle of the sprayer is often sprayed upwards, the large droplets and the droplets that did not hit the target fall to the ground under the action of gravity, resulting in a large amount of liquid medicine. Waste, but also a great pollution to the environment

Studies have shown that a large amount of liquid medicine (more than 70%) is not deposited on the target, and the loss of this part of the liquid medicine to the environment has caused harm to the personal safety of the operator and the ecological environment
