AI Technical Summary

Problems solved by technology

Their shortcomings mainly include the following three aspects: one is that the maximum range of the original rocker sprinkler is reduced, which leads to an increase in the investment of the sprinkler irrigation project; the other is that the spraying domain is a regular symmetrical figure and cannot be used for irregularly shaped plots. Sprinkler irrigation; the third is that fluctuations in pressure and flow have an adverse effect on the stability of the sprinkler irrigation system

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific examples completed by the inventor.

[0015] see figure 1 , figure 2 , according to the technical solution of the present invention, the rocker-arm spray head of the non-circular spraying area includes an original rocker-arm spray head, which is characterized in that it also includes a cam with an annular dovetail groove 3 installed on the spray head base 1 Roller 4 is arranged in the annular dovetail groove 3 of disk 2 and cam disk 2, and the ejector rod 5 is connected to the roller 4, and the ejector rod 5 and the connecting rod 8 are connected through the movable hinge 7 and the hinge 9 fixed on the nozzle 10 , and is fixed on the nozzle body by the guide ring 6; the front end of the connecting rod 8 is connected with a broken water screw 12, and the broken water screw 12 extends to the front of the nozzle 11.

[0016] The above-mentioned cam ...

Abstract

On the base of organic swing arm sprinkler head a cam disk is mounted, the transmission action of the cam can make the water-breaking screw mounted in the front of spray nozzle, upward and downward move to breave water with the rotation of sprinkler head to change the sprinkling range, theoretically, it can sprinkle the graph with arbitrary boundary form under the condition of no influencing maximum sprinkling range of original sprinkler head, and can completely eliminate the phenomena of heavy sprinkling, lost sprinkling and sprinkling out of boundary. It is simple in structure, low in cost, can be extensively used for sprinkling irrigation works.

Description

1. Technical field [0001] The invention belongs to the field of mechanical parts manufacturing, and relates to a sprinkler irrigation device for farmland, gardens and flower nurseries, and in particular to a rocker-arm sprinkler head for a non-circular sprinkler field. 2. Background technology [0002] The rocker-arm sprinkler is the most widely used sprinkler head in sprinkler irrigation technology, but the disadvantage of the rocker-arm sprinkler is that it can only spray a circular or fan-shaped area, which inevitably leads to heavy spraying, missed spraying and out-of-boundary spraying when the sprinkler head is combined. Spraying and other phenomena lead to increased investment in sprinkler irrigation projects, decreased spraying uniformity, serious waste of water resources, and outside spraying will also affect road safety and landscape effects. [0003] Existing technologies such as Chinese Patent Application Nos. 00215392.0, 00257672.4 and 01247020.1 disclose non-cir...
