Device with adjustable spraying range and for mixing and spraying pesticide with fixed quantity and fixed ratio

Abstract

The invention discloses a device with an adjustable spraying range and for mixing and spraying pesticide with a fixed quantity and a fixed ratio. The device comprises a base, a mixing box is fixedly arranged at the top of the base, a motor is fixedly arranged in the center of the top of the mixing box, a motor shaft at the bottom of the motor penetrates through the bottom wall of the mixing box and is fixedly connected with a rotary shaft, and several stirring blades are fixedly installed at the left side and the right side of the rotary shaft; an energy supply box is fixedly arranged at the right side of the top of the base, a water pump is fixedly arranged at the top of the energy supply box, and a water pumping pipe is connected to the water inlet end of the water pump; a water outlet pipe is arranged above the energy supply box, the left end of the water outlet pipe is connected with the water outlet end of the water pump through a hose, and a nozzle is fixedly installed at the right end of the water outlet pipe. According to the device, through rotation of the stirring blades and spiral blades, the pesticide is mixed, when the spiral blades rotate, liquid at the bottom of themixing box is driven to move upwards, thus the pesticide is driven to roll up and down, and the mixing effect and the mixing efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a quantitative and fixed-ratio mixing spraying device for pesticides that can adjust the spraying range. Background technique [0002] Pesticide refers to a class of drugs used to kill insects, bacteria, and harmful animals (or weeds) in order to ensure and promote the growth of plants and crops in agricultural production. Specifically refers to pesticides used in agriculture to control diseases and insect pests, regulate plant growth, and kill weeds. [0003] Now small-scale pesticide spraying mostly uses a backpack-type pesticide spraying box to spray pesticides. This kind of backpack-type pesticide spraying box mainly uses manpower as the driving force for pesticide spraying. Pesticide spraying wastes time and energy, and its effective spraying area is small and spraying efficiency is low. ; In order to kill insects and weeds, it is often necessary to mix a var...

Problems solved by technology

[0003] Now small-scale pesticide spraying mostly uses a backpack-type pesticide spraying box to spray pesticides. This kind of backpack-type pesticide spraying box mainly uses manpower as the driving force for pesticide spraying. Pesticide spraying wastes time and energy, and its effective spraying area is small and spraying efficiency is low. ; In order to kill insects and weeds, it is often necessary to mix a variety of pesticides in proportion to make pesticides that can remove different weeds or different pests. The proportion and amount of pesticides are generally controlled by farmers based on experience or medicine bottle capacity. Proportioning, its accuracy is low, after the proportioning, manual stirring is used, the mixing of pesticides is not uniform enough, and the capacity of the spraying box is limited, and the proportioning needs to be re-proportioned after spraying, resulting in low spraying efficiency and relatively large workload
