Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to an automatic spraying device for greenhouse planting. Background Art

[0002] In order to avoid diseases and pests during the cultivation of crops in greenhouses, crops need to be sprayed with pesticides regularly. In order to ensure the normal growth of crops and obtain high and stable yields, crops grown in greenhouses have faster metabolism and greater nutritional requirements for growth, so they need to be sprayed regularly or irregularly. The "greenhouse spraying device" disclosed in the application number "CN212325224U" has solved the problem that it becomes very difficult for people to spray pesticides on crops of different heights in the greenhouse. If the crops are relatively high, people need to raise their hands for a long time to spray. In the case of a large amount of manpower consumption, there will be technical disadvantages such as inadequate spraying, which ultimately leads to unobvious spraying effects. However, in actual use, spraying devices with similar structures still have many defects, such as lack of automated mobile spraying. The existing spraying devices use handheld mobile spraying on the ground. The mobile ground spraying device not only destroys the planting soil, but also increases the workload of the staff; it does not have the function of filtering the liquid medicine, which causes incompletely dissolved medicines to easily clog the pipeline, which not only affects the spraying efficiency, but also increases the maintenance cost. Therefore, it is necessary to design an automatic spraying device for greenhouse planting. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic spraying device for greenhouse planting to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic spraying device for greenhouse planting, comprising a mobile frame, a mounting box, and a guide rail rod, the mobile frame is movably mounted on the top of the guide rail rod through a protective side wheel, a driving wheel is rotatably mounted inside the mobile frame, a worm gear is fixedly mounted on the outer center of the driving wheel, a mounting box is fixedly mounted inside the mobile frame, a lifting frame is mounted on the outer side of the mounting box through an electric push rod, a filter tank is sleeved on the bottom of the lifting frame, a sealing cover is threadedly mounted on one side of the filter tank, a filter screen is fixedly mounted on one side of the sealing cover, a spray pipe is fixedly mounted on the bottom of the filter tank, and a liquid medicine tank is mounted on the top of the mobile frame through a slot lock.

The controller is electrically connected to the booster pump, the drive motor, the solenoid valve, and the electric push rod through a wire, which is convenient for the operation of the intelligent control device, and the booster pump generates high-pressure gas when it is powered on. The high-pressure gas is transported to the inside of the liquid medicine tank through the high-pressure pipe, so that a high-pressure environment is formed inside the liquid medicine tank. Under the action of high pressure, the range of liquid medicine sprayed by the spraying pipe can be expanded.

[0010] Preferably, a driving motor is fixedly installed at the bottom of the installation box, a worm is fixedly installed at the output end of the driving motor, and the worm is engaged with the worm wheel.
