Movable hose irrigation device for greenhouses

Abstract

The invention belongs to the technical field of agricultural irrigation devices, and particularly relates to a movable hose irrigation device for greenhouses. The movable hose irrigation device comprises operation guide rails, operation trolleys, connection points, trolley pulling devices, pesticide dissolving devices, connection pipelines, spray nozzles, hoses and a sprinkler irrigation branch pipe. The operation trolleys are mounted on the operation guide rails, the corresponding trolley pulling device is arranged at an end of each operation guide rail, the bottoms of the operation trolleys are connected with the hoses by the connection points, one end of each connection pipeline is connected with the corresponding pesticide dissolving device, the other end of each connection pipeline is connected with the corresponding hose, the hoses are connected with the sprinkler irrigation branch pipe, and the spray nozzles are mounted on the sprinkler irrigation branch pipe. The movable hose irrigation device has the advantages that the quantities of hose pipelines and miniature spray nozzles can be reduced, and accordingly the equipment cost can be lowered; the miniature spray nozzles are densely arrayed, accordingly, sprayed water which drips on the ground is perfect in distribution uniformity and can be directly sprayed, and excellent irrigation effects can be realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation devices, in particular to a movable hose irrigation device for greenhouses. Background technique [0002] Over the years, facility agriculture has been vigorously developed, and the number of greenhouses has been increasing year by year. Water-saving irrigation is an important part of efficient agricultural water use. Its essence is timely and appropriate irrigation to meet the physiological and ecological water requirements of crops as much as possible. The key to water technology is to improve the utilization rate and efficiency of irrigation water. Most of the solar greenhouse irrigation in my country still uses flood irrigation, and the water utilization rate is only 40%. After adopting pipeline water delivery and sprinkler irrigation technology, 60% of water can be saved. %, and the water utilization rate has increased to over 90%. At present, the rapid development of facility a...

Problems solved by technology

Drip irrigation is mainly used for the production of single equidistant planting plants; sprinkler irrigation is low-pressure, partial irrigation, and micro-spraying is good, which is conducive to increasing the humidity of the greenhouse, saving water and low energy consumption; sprinkler irrigation is often used for irrigation of the seedling trays in the linked greenhouse, It can also be used to cool the greenhouse in summer. In the greenhouse, the sprinkler irrigation equipment used for the production of densely planted plants has two mechanisms: fixed nozzles and movable nozzles. Usually, the fixed sprinkler irrigation sprinkler water distribution is not uniform enough, and the dripping water needs to be dripped in the soil. Only by doing diffusion movement can the spraying water be evenly distributed and reasonable. However, in the greenhouse production of potted and bagged crops and plug seedlings, due to the restrictions of pots, bags, plugs and other containers, they cannot adapt to fixed sprinklers.
