Water circulation system of planting machine

Abstract

The invention provides a water circulation system of a planting machine. The water circulation system comprises water inlets located in upper portions of each layer of planting grooves and used for injecting water or nutrient solutions into the planting grooves, and water level limiting water outlets formed in the planting grooves and used for limiting the water level of the water or nutrient solutions in the planting grooves. Each layer of planting grooves are connected through columns penetrating through the middles in a supported mode to form an integral structure. The positions of the water inlets corresponding to the planting grooves and the positions of the water level limiting water outlets are respectively located around the columns, and their connecting lines are crossed with thecentral axes of the columns, so that water flow between the water inlets and the water level limiting water outlets cannot flow along the shortest straight paths in the corresponding planting grooves.According to the water circulation system of the planting machine, the oxygen content in the water or nutrient solutions in the planting grooves is increased by arranging the positions of the water inlets corresponding to the planting grooves and the positions of the water level limiting water outlets at intervals, the problem of uneven distribution of nutrients in the nutrient solutions is improved, and accordingly plant growth is facilitated.

Description

technical field [0001] The invention relates to a water circulation system of a plant planting machine applied in the field of plant planting. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to their own health, especially the quality of vegetables eaten every day (such as green, pollution-free, freshness) has a higher demand, so more and more A person uses a plant planter to grow or preserve vegetables and other plants indoors. [0003] The plant planting machine in the prior art has a multi-layer structure, each layer is provided with a planting tank for holding water or nutrient solution, a planting cover plate for planting plants is provided above the planting tank, and a planting cover plate is provided for inserting the plant. A round hole in water or nutrient solution. [0004] In the prior art, the water or nutrient solution in the planting tank is generally static. After standing still for a lon...
