First, the advantages of ultra-low volume sprayer
Compared with commonly used sprayers, the ultra-low volume sprayer is faster and more efficient in the control of plant, lawn and crop diseases and insect pests. , light, cost-saving and other advantages. The specific performance is as follows:
1. Less water consumption: The ultra-low volume sprayer uses pesticide stock solution, or only needs to be diluted at a very low time, so it does not require a lot of water.
2. Less dosage: about 100 grams of spray liquid per mu, instead of tens of kilograms or even hundreds of kilograms. Therefore, the labor intensity can be greatly reduced and labor is saved during use.
3. The droplets are evenly distributed: the ultra-low volume sprayer does not spray the liquid directly on the plants, but relies on the wind to disperse and drift the droplets with a diameter of only tens of microns, and then spray the droplets around the plants. Under the action of “micro air flow”, the mist droplets are evenly distributed on the front, back and sides of the leaves and the whole plant. In this way, the killing rate of the pests is higher than that of the pesticides diluted with a large amount of water, especially for some pests that have developed resistance to the pesticides, and the effect is better. Because the killing function of the pesticide stock solution is several times or even dozens of times higher than that after dilution with water.
4. Easy to use: When spraying with an ultra-low volume sprayer, keep the head at a height of about 1 meter above the plant. Since this type of sprayer dispenses with the liquid spray head, the liquid flows out on its own when the bottle is lowered. Therefore, when the motor is not turned on, the medicine bottle should be below and the handpiece should be above. When spraying medicine, the motor should be started first, and then the position of the medicine bottle and the machine head should be changed, so that the medicine bottle is above, the bottle mouth is downward, the bottle body is perpendicular to the ground, and the medicine liquid will flow out by itself.
Second, how to use the ultra-low volume sprayer
The ultra-low volume sprayer does not require special processing for the agent, as long as it is added to the original drug (crude oil). A small amount of solvent is used to solve the problem of spray quality due to excessive viscosity of the agent. Every 667 square meters only need to spray less than 330 ml of pesticides to get good control effect. Use in low water areas.
When using the ultra-low volume spray, the following points should be mastered: When using, the operator must walk first, and then turn on the infusion switch after the various parts of the machine are running normally. At the same time, the walking speed must always be kept the same. When stopping spraying, first turn off the infusion switch, and then turn off the machine. When spraying, start from the downwind direction, and the spraying direction should be consistent with the natural wind direction.
When spraying in the field, use side spray technology. The spray nozzle should not be directly facing the crop, but must have a certain angle to the crop. The angle should be determined according to the natural wind speed. The principle is that when the wind speed is large, the angle should be large, When the wind speed is small, the angle is small. When the natural wind is greater than level 3, ultra-low volume spray should not be applied. When spraying, the turret of the nozzle atomizer should not touch the crops to prevent the runner from being damaged. Do not overfill the liquid to prevent overflow. After each use, discharge the remaining liquid medicine in the liquid medicine tank and infusion tube, and wipe the whole machine clean. Before storing and storing, it should be cleaned once, and the metal parts should be coated with anti-rust oil, and then stored in a ventilated and dry place.
Three. Common faults and troubleshooting methods of ultra-low volume sprayers
1. The spray volume is reduced or not sprayed. During maintenance, if it is found that the valve core of the throttle valve is not in the correct position, the valve core position can be re-aligned; if the infusion switch is blocked, the infusion switch must be cleaned; if the orifice of the throttle valve is blocked, the valve core should be cleaned to throttle If the outlet hole of the shaft head is blocked, the infusion hole of the shaft head should be cleaned; if the pressurization of the liquid medicine tank is insufficient or the air is leaking, the joint can be re-pressurized so that the gap faces the fan; if the liquid medicine tank is not tightened, it should be Retighten the tank cap.
2. The mist particles are obviously thick or the speed of the runner is low. If it is found that the speed of the gasoline engine is not enough, the gasoline engine should be adjusted or repaired; if the swivel bearing is short of oil, the bearing should be cleaned and lubricated; if the bearing is worn, the new bearing should be replaced; The grille should be cleaned or replaced with a new one.
