Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouse equipment, in particular to a magnetic navigation type greenhouse spraying vehicle. Background Art

[0002] With the improvement of people's living standards in my country, vegetable greenhouses have been widely used in agriculture. However, traditional greenhouse cultivation is labor-intensive, resulting in low production efficiency. Therefore, a number of automated equipment have been introduced in modern greenhouses to reduce labor input and improve work efficiency.

[0003] For example, in the production process of spraying pesticides or fertilizers on crops in greenhouses, there are now automated spraying equipment to operate, but the current greenhouse spraying equipment is generally set on the top of the greenhouse, and the crops are sprayed with pesticides or foliar fertilizers through fixed nozzles or walking nozzles. These devices can greatly improve efficiency, but there are also some disadvantages. In the actual planting process, the spraying equipment on the top of the greenhouse can only spray on the upper surface of the crop leaves, and cannot spray on the bottom of the leaves. Foliar fertilizers sprayed on the bottom of the leaves can be better absorbed, and the same problem exists with pesticide spraying. The pests and diseases on the bottom of the leaves cannot be killed in a timely and effective manner, which will affect the yield of the crops to a certain extent. Summary of the invention
