The present invention relates to an
insect expelling device for forest
plant resource protection and relates to the technical field of forest environment protection devices. The
insect expelling device for the forest
plant resource protection comprises a base seat, a
liquid storage tank, a pressurization pump, a water outlet
pipe, a supporting component and a spraying component, the liquid storagetank is fixedly arranged on a front side wall of the base seat, the pressurization pump is fixedly arranged on the front side wall of the base seat, and besides, an inlet end of the pressurization pump is arranged at a lower end of a side wall of the
liquid storage tank in a penetrating manner, and an outlet end of the pressurization pump is provided with the water outlet
pipe in series; and thebase seat is arranged on the supporting component in a sliding manner, the spraying component is fixedly arranged on the base seat, besides, the spraying component is arranged above the liquid storagetank, and the water outlet
pipe communicates with an inlet end of the spraying component in series. When the
insect expelling device is arranged on a
tree trunk through a sliding rail, the
liquid storage tank communicates with the pressurization pump to send the pressurization pump into a tree crown, height of medicinal liquid in the
liquid storage tank pressed by the pressurization pump is reduced,
energy consumption of the pressurization pump is further reduced, endurance time of a storage battery is guaranteed, and the device is convenient to move and use.
