Knapsack electric sprayer plant protection is an indispensable helper

The knapsack electric sprayer is one of the plant protection machines and is widely used in agricultural plant protection operations.
In the 1990s, the use of knapsack electric sprayers increased gradually, but because of the large shape, it was not conducive to long-term work. In 2005, the WH-5 backpack-type ultra-low-volume electric sprayer was born to avoid the disadvantages of the traditional knapsack electric sprayer. Its characteristics are:
1. The appearance design is updated: the overall design is more in line with people's traditional habits - piggyback, novel appearance, reasonable structure, outstanding personality and simple operation.
2. The capacity of the liquid medicine tank is large: the capacity of the liquid medicine barrel is 10 liters (10 kg), and it can spray 3-5 mu (666.7 square meters/mu).
3, the amount of spray is large: by adjusting the speed of the centrifuge and increasing the speed of the liquid flow, so that the spray of fog is more and dense. Therefore, the spray is more thoughtful and the coverage is wider.
4, dual-use battery is more convenient: on the basis of the use of four sections of the first battery, and equipped with a battery as a power supply, this battery is maintenance-free, large capacity, power enough, use more labor-saving.
5, the nozzle is more flexible: flexible nozzle allows the user to do more freely, where to spray where to spray.
