Description

Technical Field

[0001] The utility model belongs to the technical field of aeroponic devices, and in particular relates to a device for aeroponic cultivation of asparagus. Background Art

[0002] In the context of the rapid development of modern agriculture, asparagus, as a vegetable with high nutritional value, has become the focus of attention in the agricultural field in terms of its cultivation technology and efficiency. Traditional asparagus cultivation methods mostly use soil cultivation, which has problems such as uneven irrigation, low nutrient absorption efficiency, susceptibility to pests and diseases, and insufficient land resource utilization. Especially in the irrigation process, traditional irrigation methods such as flooding and drip irrigation often make it difficult to achieve precise control of the asparagus root area, resulting in a waste of water and nutrients, and also increasing the risk of disease transmission.

[0003] With the rise of soilless cultivation technology, aeroponic technology has gradually gained favor for its unique advantages. By spraying fine nutrient solution droplets directly onto the plant roots, aeroponic technology achieves direct absorption and efficient utilization of nutrients, reduces water evaporation and loss, and also avoids the risk of soil-borne diseases. However, existing aeroponic devices still have some shortcomings in design and application. For example, many aeroponic devices use static or simple rotating planting trays. Although this method can improve irrigation uniformity to a certain extent, there are still irrigation dead spots, and it is difficult to flexibly adjust the irrigation strategy according to the growth of asparagus roots; in addition, because the roots of asparagus grow quickly and can grow up to two meters long, the traditional fixed sprinkler atomizer nozzles cannot perform efficient and water-saving irrigation according to the length of the root system.

The planting tray can be automatically rotated while revolving, and the atomizing nozzle mechanism that can be precisely controlled by multiple valves can be used to achieve uniform and sufficient aerosol irrigation of the asparagus root system, and effectively reduce resource waste. The planetary gear mechanism 7 includes a main shaft 71, and a sun gear 72 is installed on the main shaft 71. The sun gear 72 is meshed and connected to multiple planetary gears 73. The planetary gears 73 are installed on the planetary gear shaft 74 and the planetary gears 73 are meshed and connected to the outer outer ring gear 75. The planting tray 8 is installed at the bottom end of the planetary gear shaft 74. The planetary gear shaft 74 is rotatably installed on the planetary frame 77. The outer ring gear 75 is installed on the inner side of the fixed seat 76. 76 is installed on the box body 1, and a planetary gear mechanism with a simple structure can drive multiple planting trays 8 to rotate and revolve at the same time, so that the asparagus on the planting trays 8 can be evenly and fully watered. The driving pulley and the driven pulley in the belt transmission mechanism 6 are respectively installed on the output shaft of the motor 5 and the main shaft 71. The motor 5 can drive the main shaft 71 to rotate stably through the belt transmission mechanism 6. The inner wall of the fixed seat 76 is connected with a supporting plate 78, and the supporting plate 78 is slidably connected to the bottom surface of the planetary carrier 77. The supporting plate 78 provides support for the planetary carrier 77 to ensure the position stability of the planetary gear 73, so that the planetary gear 73 is stably meshed with the sun gear 72 and the outer ring gear 75.
