Electric sprayer is now a more common application of farmland pesticide application equipment, and compared with the traditional sprayer pressure, good atomization effect, fast operation speed, energy saving and other advantages; Disadvantages are also more obvious, poor endurance.
1, suitable for spraying herbicide operation. For spraying herbicides, the requirements for atomization effect are not particularly high, and this kind of equipment with relatively poor atomization effect can fully meet the needs of weed control operations. Especially for those paddy fields that are not suitable for mechanized operation, the use of electric sprayers for stem and leaf spraying is preferred. The pressure of sprinkler head is large, and the amount of weed leaf liquid is large, which is more conducive to weed leaf absorption of herbicide liquid.
2, it is best to use a single nozzle. The pressure of the electric sprayer is large, and the spray amount of the liquid is larger than that of the traditional hand pressure sprayer. This means that the same 15-liter volume of the spray can, the operation area of the electric sprayer is smaller than that of the traditional hand pressure sprayer. Moreover, many farmers prefer to use double sprinkler operations, so that the consumption of liquid medicine is greater, especially the cost of farmland weed control operations will increase. The use of a single nozzle can minimize the consumption of chemicals.
3, intermittent charging or prepare spare batteries. Because the power stored in the battery is used as the power source of the injection agent, there will inevitably be battery power loss. Usually, the amount of work after this type of electric sprayer is fully charged is about 15-20 POTS, and you want to ensure that the daily amount of work is to ensure that the battery has sufficient power. Either use your lunch break to recharge, or prepare a replacement battery, or just have an extra set of electric sprayers.
4. The liquid medicine is best filtered. The pressure of the electric atomizer is large, the atomization effect of the nozzle is better, and the nozzle is more easily blocked and affects the application effect. In particular, many farmer friends prepare pharmaceutical water is the water in the ditch near the farmland, there are a lot of soil particles suspended matter, easy to block the nozzle. It is recommended that when pouring agents into the spray can, it is best to have 1-2 layers of gauze, window screens and other small aperture fabrics, stockings for filtering to reduce the risk of blocking the nozzle.
The above are some of my views on this issue. Please forgive me if there is any inappropriateness.
First, after the purchase of the machine should be charged immediately, the battery full. Because the battery is only partially stored before leaving the factory, it can be used after being fully filled. At present, most electric sprayer chargers use \"switching power supply\" to charge the battery, not the previous transformer test charger; Because the switching power supply saves power and is highly efficient, the general charging time is about 6-8 hours, and the sprayer battery can be charged well
1 connection
All newly purchased electric sprayers should be connected first when used for the first time. The method is: unscrew the nozzle at the end of the handle, then take out the large O-ring with the function of water leakage and pressure retention, and put it into the groove of the handle port. Then check whether the spray rod is smooth, and then connect the spray rod to the handle. Note that a large O-ring should also be placed on the groove of the end mouth of the spray rod. Finally, select a suitable nozzle, unscrew it into the large O-ring, and then tightly screw it on the spray rod, so that the docking work is completed.
2 Test Run
The next step is a trial run. It is aimed at new users. First of all, the battery is reset, the method is: take out the battery parallel rotation 180°, the pole ear according to the red line to the red head, the black line to the black head firmly connected, and then the right loading, buckle the battery hook can be. Then turn on the power switch and start the water pump. Then check the pump has no noise, if there is a noise indicates that the pump has a problem, need to be replaced. The pump should not be idled for a long time when testing the machine, and should be shut down in time.
3 Test Spray
After the test machine is no problem, unscrew the lid of the barrel, add an appropriate amount of water, turn on the power switch, turn on the handle switch, and test spray. Check whether the joints are sealed and firm, whether the pressure is normal, and whether the fog effect is ideal. After half a minute of spray test, turn off the handle switch, maintain the pressure for 1 minute, and then check whether there is leakage of the outlet pipe and handle. At this time, if the pump appears intermittent beating is a normal phenomenon.
4 Charging
The newly purchased electric sprayer is used without charging the battery as required, which will affect the service life of the battery. Therefore, after the trial boot is not abnormal, the battery must be charged immediately. The first charging time is generally 8-10 hours, and the long and short charging time after the battery is used depends on the battery.
The specific method is: Connect the charger plug to 220V AC power, and the power signal light is not on. Then insert the charger DC plug into the DC jack at the bottom of the barrel, and the signal light is red, indicating that it is charging. When the signal light turns from red to green, it means that the charging is basically complete, but the power is not really full at this time, and it needs to be charged for another 1-2 hours. After the battery is charged, unplug the DC plug first, and then disconnect the charger.
5 Adjust the straps
After the above work is completed, it is necessary to adjust the strap to the appropriate length through the elastic buckle, and then adjust the position of the shoulder pad. Then hand pull the strap, check whether the strap is fixed firmly, whether the length is the same, and whether the connection part is reliable. It is good to be able to carry the sprayer flexibly and feel the appropriate tightness.
6 Add liquid medicine
When using liquid medicine, first add the required water into the barrel, and the maximum water level should be 5 cm away from the mouth of the barrel. Then pour the liquid medicine into the large filter according to the amount; To use a powder, pour it into another container, stir it up with water, and then pour it into a sprayer filled with water. It is forbidden to remove the large filter net and directly add water and medicine, it is forbidden to directly pour powder into the bucket, and it is forbidden to sink the bucket into the water to hold water. After the liquid medicine is added, the lid should be tightened to prevent air leakage and liquid medicine overflow.
7 Spray operation
When starting the spray operation, be sure to wear gloves and masks, and if possible, wear protective clothing to prevent poisoning. The method is: hold the handle with the right hand, turn on the power switch with the left hand, start the pump, then press down the handle switch handle, you can spray, loosen the handle switch handle to turn off the spray. If you need to spray for a long time, just put the red card on the handle in place, so that the handle can be kept in the \"normally open\" state even without hand pressure, which can reduce physical exertion. If you need to add water or medicine during the process or stop the operation for a long time, the power supply must be turned off.
Charging time problem: the newly bought electric sprayer should be charged for 12 hours, and then fully charged before usual use (generally more than 8 hours), if not used for a long time, it is best to charge once within 3 months, which is conducive to protecting the life of the battery.

It is worth noting that, because it is electric, do not wet the battery, let alone put the medicine bucket directly into the water to fill the water, it is best to wipe dry after storage in a ventilated dry place.
