Problems solved by technology
Its disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered
For larger plants and drip irrigation in relatively concentrated locations, a control device that is convenient to adjust the amount of drip irrigation one by one, and adjust the amount of dripping water anytime and anywhere; Gravity) for drip irrigation, existing equipment does not work due to too little pressure

The present invention relates to the technical field of agricultural devices, and discloses a drip-irrigation controller for crops. The controller comprises: a housing, an upper pressing cover and a lower pressing cover, wherein the upper pressing cover and the lower pressing cover are sleeved in the housing from top to bottom in sequence, a water seepage cavity is formed between the upper pressing cover and the lower pressing cover, the upper pressing cover has an water inlet, the water inlet is connected with a water inlet pipe, the lower pressing cover has a water outlet, the water outlet is connected to a water outlet pipe, an upper elastic member is connected between the upper pressing cover and an inner wall of the housing, and an lower elastic member is connected between the lower pressing cover and the inner wall of the housing; and an airbag is arranged between the upper pressing cover and the lower pressing cover, the outer surface of the airbag tightly leans against the water inlet and the water outlet, and an inflation apparatus is connected with the airbag. By adopting the scheme, adjustment of water dripping amount in a drip-irrigation process is facilitated, the adjustment mode is convenient to operate, drip-irrigation is performed by the gravity of water, so that the dependence on tap water (pressure water) is eliminated, and the environment application ability is strong.
Description
technical field [0001] The invention relates to the technical field of agricultural equipment. Background technique [0002] Drip irrigation is the use of plastic pipes to send water to the roots of crops through holes or drippers on capillaries with a diameter of about 10mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for irrigation of field crops in places where there is drought and water shortage. Its disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered. For larger plants ...
