Fixed sprinkling irrigation sector nozzle

Abstract

The invention relates to a sprinkling irrigation device, in particular to a fixed sprinkling irrigation sector nozzle. The fixed sprinkling irrigation sector nozzle comprises a nozzle body (1), an impeller (2), a bolt (3) and a rubber water seal ring (4). According to the working principle of the sprinkling irrigation device, a water flow is gathered though the nozzle and jetted to the impeller (2) at a certain angle, when the water flow flows through the positive convex curved surface plate surfaces and the back plate surfaces of blades, the flowing speeds of the water flow are different, thus the Bernoulli effect is generated to form tension on the positive convex curved surface plate surfaces, in addition, tension on the positive convex curved surface plate surfaces is also generated through the wall attachment effect of the water flow, and the impeller (2) can overcome friction force and air resistance under pulling of the two parts of tension to rotate at the high speed from the low water pressure to the high water pressure; and thus the film-type water flow after wall attachment is sprinkled more evenly. The fixed sprinkling irrigation sector nozzle is simpler in structure, convenient to maintain, low in manufacturing cost, suitable for China national conditions and easy to apply and popularize.

Description

technical field [0001] The invention relates to a sprinkler irrigation device, in particular to a sprinkler head with a fan-shaped or circular sprinkler area. Background technique [0002] my country is a country that is relatively scarce in water resources, and saving water has important and far-reaching significance in the social and economic development of our country. Sprinkler irrigation is an important water-saving technology. Sprinkler irrigation is to send the pressurized water formed by the pressure of the water pump or the natural drop to the field through the pressure pipe, and then spray it into the air through the nozzle to form small water droplets, which are evenly sprinkled on the farmland or garden. , to achieve the purpose of irrigation. Generally speaking, the obvious advantages of sprinkler irrigation are uniform irrigation, less cultivated land, labor saving, 30-50% water saving compared with ordinary irrigation, 20-30% increase in crop production, and ...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the various defects of the above-mentioned existing sprinkler heads, apply the new sprinkler irrigation working principle to redesign the structure of the fixed sprinkler irrigation sector sprinkler head, and solve the problem of impeller stop and reverse rotation and water sprinkling of the existing fixed sprinkler irrigation sector sprinkler heads. The problems of poor uniformity and small adaptable range of working water pressure, as well as the problem of dead angle of spraying caused by most of the existing sprinklers that can only spray in a full circular area and the complex structure of sprinklers and high manufacturing costs are solved.
