Technical Field
[0001] The utility model belongs to the technical field of greenhouse spraying equipment, in particular to a greenhouse spraying device. Background Art
[0002] A greenhouse, also known as a hothouse, is a facility used to cultivate plants, allowing light to pass through and maintaining heat (or heating). It provides a growth period and increases yields during seasons unsuitable for plant growth, and is often used to cultivate or raise seedlings of thermophilic vegetables, flowers, trees, and other plants during low-temperature seasons. There are many types of greenhouses, which can be further categorized by roof truss materials, lighting materials, external shapes, and heating conditions. Existing greenhouse pesticide spraying devices often have a medicine box connected to the top, and a spraying rod connected to the bottom of the box to spray pesticides on crops within the greenhouse. However, these devices have certain drawbacks. For example, the height of the spraying rod is fixed. When the crops are in the seedling stage, the spraying rod is too high, preventing the pesticide from being sprayed directly onto the crop leaves. As the crops grow, the spray can only be sprayed on the top of the crops, and the lower leaves of the crops are not exposed to the pesticide solution, resulting in a poor insecticide control effect. Therefore, it is necessary to develop a pesticide spraying device that can adapt to multiple crop growth periods to meet this need. Utility Model Content

[0008] Compared with the prior art, the utility model has the following advantages:
[0009] 1. The utility model is provided with a slider, which can move horizontally in the greenhouse to meet the needs of spraying pesticides at various positions in the greenhouse. A telescopic electric cylinder is provided at the bottom of the greenhouse to adjust the height of the spraying rod.
