Flow-controllable drip irrigation device for seedling culture box

Abstract

The invention discloses a flow-controllable drip irrigation device for a seedling culture box. The device comprises a seedling culture box body, a first opening is formed in the position, close to the center, of the top of the seedling culture box body, a rotating mechanism is arranged in an inner cavity of the first opening, and air outlets are formed in the positions, close to the bottom, of the left side and the right side of the seedling culture box body. A water storage tank is fixedly connected to a position, close to the bottom, of the inner cavity of the seedling box body. By means of mutual cooperation of all the components, the device can effectively enlarge the drip irrigation range during drip irrigation through rotation of a plurality of drip irrigation nozzles, so that the drip irrigation area is increased, the material size is saved, and the cost of the device is reduced; And through arrangement of second fan blades, air in the inner cavity of the seedling culture box body can circulate, the seedling culture environment is improved, and the situation that a second filter screen is blocked is prevented by cleaning the second filter screen during water pumping.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a seedling box drip irrigation device with controllable flow rate. Background technique [0002] With the continuous development of science, people's improvement of agricultural planting level is becoming more and more obvious. In the process of watering seedlings, in order to save water resources to the greatest extent, a drip irrigation device was invented to effectively improve the utilization rate of water; [0003] After long-term use of traditional drip irrigation devices, because the water quality contains minerals such as sand and stones, it is easy to block the internal drip tube, causing damage to the entire drip irrigation device, and it cannot perform uniform drip irrigation during drip irrigation, and the drip irrigation area is small. It cannot meet the needs of drip irrigation and planting, but the existing seedling boxes do not have water circulation...

AI Technical Summary

Problems solved by technology

[0003] After long-term use of traditional drip irrigation devices, because the water quality contains minerals such as sand and stones, it is easy to block the internal drip tube, causing damage to the entire drip irrigation device, and it cannot perform uniform drip irrigation during drip irrigation, and the drip irrigation area is small. It cannot meet the needs of drip irrigation and planting, but the existing seedling boxes do not have water circulation, which leads to waste of infiltrated water resources, and the ventilation effect is poor, which cannot ensure the ventilation environment required for seedling cultivation, and the soil needs to be manually loosened. Therefore, there is an urgent need for an energy-saving drip irrigation device for agricultural greenhouses to solve the above problems
