The invention discloses a negative pressure liquid spraying system and unmanned equipment, and relates to the technical field of liquid spraying. The negative pressure liquid spraying system includes a spray head, an air circuit assembly and a liquid circuit assembly. The spray head is provided with a cavity and a first inlet, a second inlet and an outlet communicated with the cavity. The air circuit assembly communicates with the first inlet, and is used for independently and controllably delivering compressed air through the cavity of the first inlet box. The liquid circuit assembly communicates with the second inlet, and is used for independently and controllably delivering liquid to the cavity through the second inlet, so that the liquid can be ejected from the outlet under the action of compressed air. The system can independently control the working status of the air circuit components and liquid circuit components according to the operation requirements, so as to realize the selection and control of liquid spraying operation types such as quantitative spraying, thereby improving the controllability of the system. At the same time, by controlling the air circuit components to work independently, the residual liquid in the nozzle can be sprayed out, so that the spraying liquid can be saved, the spraying effect can be improved, and the influence of the residual liquid on the nozzle can be avoided, and the service life of the nozzle can be improved.
Description
technical field [0001] The invention relates to the technical field of liquid spraying, in particular to a negative pressure liquid spraying system and unmanned equipment. Background technique [0002] In the existing technology, unmanned vehicles, drones and other unmanned equipment can be used to carry out agricultural operations such as spraying chemicals, and agricultural operations through unmanned equipment can effectively improve the efficiency of agricultural operations. [0003] However, it has been found through research that the liquid injection device integrated on the unmanned equipment in the prior art has technical problems such as poor controllability and serious waste of liquid. Contents of the invention [0004] The object of the present invention includes providing a negative pressure liquid spraying system, which can independently control the working status of the gas circuit components and liquid circuit components according to the operation requiremen...
