[0002] Agriculture is an industry that uses the growth and development law of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science of studying agriculture is agronomy. The labor object of agriculture is living plants and animals, and the obtained product is the plants and animals themselves. Agriculture is a basic industry that provides support for the construction and development of the national economy. Planting refers to plant cultivation, including the cultivation of various crops, trees, fruit trees, flowers, medicinal and ornamental plants, etc. There are grain crops, economic crops, vegetable crops, green manure crops, forage crops and pasture, etc.

[0003] Sprinkling irrigation is an irrigation method that uses water pumps and pipeline systems or natural water sources to spray water with a certain pressure into the air, scatter into small water droplets or form mist to fall on plants and the ground. In the process of agricultural planting, in order to make crops survive and grow better, it is necessary to spray water on crops. The existing patent with publication number CN221948911U proposes a rice planting irrigation device with sprinkling irrigation adjustment function, which adjusts the height of the spray head to adapt to crops at different growth stages and improves the irrigation efficiency. However, the device can only adjust the height and cannot adjust the irrigation range according to the size of the cultivated land, which has certain limitations in use. Therefore, we propose a spraying device for agricultural planting, which can not only adjust the height range of the spray head, but also adjust the spraying range of the spray head, suitable for different sizes of planting sites. At the same time, the spray head rotates during sprinkling, making the sprayed water mist more uniform. CONTENT OF THE UTILITY MODEL
