Automatic water supplementing device for three-dimensional farm

Abstract

The invention discloses an automatic water supplementing device for a three-dimensional farm. The automatic water supplementing device mainly comprises a floating ball valve, a water supplementing pipe, water storage discs and water overflowing pipes, and is characterized in that the opening / closing of the floating ball valve is controlled by the water level of the lowest layer of water storage disc; after the floating ball valve is opened, water flow is fed into the uppermost layer of water storage disc along the water supplementing pipe first; when the water level is higher than a water overflow hole of the layer, the supplemented water flows into the water storage disc of the next layer through the water overflow pipe; when the water level of the lowest layer of water storage disc is higher than a set value, the floating ball valve is closed, and the water is supplemented by each layer of the water storage disc in sequence. By the adoption of the technical scheme, the supplemented water can be automatically obtained by a multi-layer planting device; the automatic water supplementing device has the benefits of simple structure, low cost, and free of manual intervention.

Description

Technical field [0001] The invention relates to the field of agricultural irrigation, in particular to an automatic irrigation water supplement device of a multilayer planting system. Background technique [0002] Today’s agriculture is developing towards mechanization, intelligence, and intensive production. For example, the Netherlands reserves a large amount of agricultural land in the suburbs and surrounding areas, and produces food, vegetables, fruits and other agricultural products through glass greenhouses with advanced facilities. The glass greenhouse area Over 110,000 km 2 75% of agricultural products are available for export after meeting their own needs. The second is to develop in the direction of three-dimensional and multi-layered. For example, Huang Shunhe, the person in charge of Sky green in Singapore, invented a 9-meter-high vegetable tower to plant 10 layers of vegetables. In order to obtain uniform light, the planting tank is constantly driven by water. Circu...
