A kind of agricultural planting water-saving micro-irrigation device and micro-irrigation method

Abstract

The invention relates to the field of micro-irrigation devices. The invention discloses a water-saving micro-irrigation device for agricultural planting and a micro-irrigation method thereof. The problem to be solved by the invention is that the mesh holes of the filter screen are easily blocked by debris in the water, which affects the water spraying effect of the device; it is troublesome to recycle the device , and when some of the nozzles of the device are damaged, it is necessary to test each nozzle and replace some of the damaged nozzles, which is time-consuming and labor-intensive to operate. The invention consists of a filtering mechanism and a conveying mechanism. The agricultural planting water-saving micro-irrigation device and its micro-irrigation method transport the water source into the connecting pipe through the water pump, filter the water transported into the three-way pipe through the filter screen, and impact the stopper when the water source is transported into the connecting pipe by the water pump, The coil spring is urged to extend downward, and the water source impacts the helical groove on the side of the block, so that the block rotates to drive the spring to rotate, and the debris on the surface of the filter screen is scraped to ensure the effect of the filter screen.

Description

technical field [0001] The invention relates to the field of micro-irrigation devices, in particular to a water-saving micro-irrigation device for agricultural planting and a micro-irrigation method thereof. Background technique [0002] With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. and cut flower cultivation; fruit tree production is used for cultivating grapes, strawberries, watermelons, melons, peaches and citrus, etc.; forestry production is used for tree seedlings, ornamental trees cultivation, etc. Equipment for irrigating and watering plants grown in. [0003] The existing irrigation and watering equipment filters the impurities in the water through the filter screen to prevent the nozzle from being blocked...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the present invention provides a water-saving micro-irrigation device for agricultural planting and a micro-irrigation method thereof, which solves the problem that the existing water-saving micro-irrigation device for agricultural planting filters impurities in water through a filter to prevent nozzle clogging. But after filtering for a long time, the mesh of the filter screen is easily blocked by sundries in the water, which affects the water spraying effect of the device; the existing device directly lays the water pipe on the ground to drip-irrigate the plants, which is troublesome when recycling the device, and When some of the nozzles of the device are damaged, it is necessary to detect each nozzle and replace some of the damaged nozzles, which is time-consuming and labor-intensive.
