Development of spray

Backpack electric spray is a kind of plant protection machinery, which is widely used in agricultural plant protection.

In the 1990s, the use rate of backpack electric spray gradually increased, but the large shape was not conducive to the operation for a long time. In 2005, WH-5 knapsack type ultra-low volume electric spray was born to avoid the disadvantages of the traditional knapsack type electric spray. Its characteristics are:

1. The appearance design is more innovative: the overall design is more in line with people's traditional habits - backpack style, with a novel and elegant appearance, reasonable structure, prominent personality, and simple operation.

2. Large capacity of medicine barrel: The medicine barrel has a capacity of 10 liters (10 kilograms) and can spray 3-5 acres (666.7 square meters/acre).

3. Large amount of spray: by adjusting the rotating speed of the centrifuge and increasing the speed of liquid medicine flow, more and more dense fog can be sprayed. Therefore, spray is more considerate and covers a wider area.

4. Dual use batteries are more convenient: In addition to using four primary batteries, a battery is also equipped as a power source. This type of battery is maintenance free, has a large capacity, and has sufficient power, making it easier to use
