Intelligent irrigation system for farmlands

Abstract

The invention discloses an intelligent irrigation system for farmlands, belonging to the technical field of agricultural equipment. The irrigation system comprises a suction pump and a water conveyingpipeline, and further comprises a sealed shell and a sewage discharge motor arranged in the sealed shell, wherein a water suction pipe is fixed to the output shaft of the sewage discharge motor, andthe inlet end of the water suction pipe extends to the outside of the sealed shell and is horizontally arranged; the inlet end of the water suction pipe is provided with a first filter net, and the outlet end of the water suction pipe and the inlet end of the water suction pump are both communicated with the interior of the closed shell. The irrigation system also comprises a controller, a motor drive module, and a flow meter arranged at the inlet end of the water conveying pipeline, wherein the controlled end of the water suction pump is connected with the output end of the controller, the flow meter, the controller, the motor drive module, and the sewage discharge motor are sequentially connected to form a sewage discharge system of the water suction pipe. The sewage discharge motor is used to remove the impurities adhering to the water suction pipe, and the sewage is automatically discharged, thus saving time and labor, and improving the irrigation efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and relates to an irrigation system, in particular to an intelligent irrigation system for farmland. Background technique [0002] In order to save groundwater and make reasonable use of water resources, many areas use river water for irrigation. Most of them use pumps to pump water directly from the river and then flood the fields. Because there are many impurities in the river water, the inlet of the pump is easily blocked. This just needs to shut down the water pump, manually cleans up the inlet of the water pump before continuing to pump water, which is time-consuming and laborious, and affects the irrigation efficiency. [0003] In addition, it is well known that flood irrigation is the most water-wasting irrigation method, and a lot of river water cannot be used effectively. If irrigation methods such as sprinkler irrigation or drip irrigation are used, the pipes and nozzles ...

[0002] In order to save groundwater and make reasonable use of water resources, many areas use river water for irrigation. Most of them use pumps to pump water directly from the river and then flood the fields. Because there are many impurities in the river water, the inlet of the pump is easily blocked. This requires shutting down the water pump, manually cleaning the inlet of the water pump before continuing to pump water, which is time-consuming and labor-intensive, and affects irrigation efficiency

[0003] In addition, it is well known that flood irrigation is the most water-wasting irrigation method, and a lot of river water cannot be used effectively. If irrigation methods such as sprinkler irrigation or drip irrigation are used, the pipes and nozzles will be blocked due to fouling of the river water, resulting in sprinkler irrigation. The irrigation efficiency of dripper and dropper is low, the maintenance cost is high, and the popularization and use are limited
