The powder spraying machine is a common device for powder spraying operation in agriculture and forestry, and is used for spraying powder medicament to a certain range so as to diffuse and distribute the powder medicament to an applied area. Because the powder has small particles and wide scattering range, the particles can be uniformly distributed and staggered with each other and stacked in the environment. Therefore, the method is particularly suitable for large-area sterilization and disinfection. For example, in a farm, a powdered medicament is ejected to remove ammonia gas, prevent feces odor, suppress bacteria, and the like. The powder spraying machine in the prior art mainly adopts a pipeline suction feeding mode or a gravity blanking mode to realize the feeding of powder. The two kinds of powder spraying equipment have advantages respectively, but have certain disadvantages respectively, for example, a pipeline suction powder sprayer is taken as an example, generally, the powder sprayer needs two hands of an operator to operate, a powder containing packaging bag is held by one hand, the powder sprayer is operated by the other hand, and a pipeline of the powder sprayer is directly inserted into the powder containing packaging bag to suck powder. Although the powder sprayer can spray powder normally, when the powder spraying amount is small or the packaging bag is too large and inconvenient to hold, the powder sprayer brings inconvenience to operators; the powder sprayer blanking by gravity needs to rely on a container on the powder sprayer to store powder in advance, which means that the gravity of the powder can be directly applied to the powder sprayer, and for flexible operation, the container can not be set too large usually, so that frequent feeding is needed when large-area powder spraying is caused, operation steps are increased, and the overall efficiency of the powder spraying is reduced.
