Problems solved by technology

At present, there are many problems in the application of this irrigation: due to the long duration and high wind speed of the strong wind in the north, the sprinkler irrigation system cannot operate normally in many cases; except for large green areas such as lawns, other vegetation is irrigated by flood irrigation The method is time-consuming and water-consuming, and it is easy to cause soil compaction; at noon in the scorching sun, the sprinkler irrigation system is still working, so it is easy for the water droplets sprayed on the plant leaves to play the role of a convex lens, burning the leaves and damaging the plants; some When the sprinkler irrigation system just stops working or when it is still working, there will be rainfall, which is undoubtedly a waste of water resources
But there is also a prominent shortcoming, that is, the automatic adjustment of the spray distance cannot be realized: due to the high speed of the water outlet, and the spray is in a very narrow beam, it is often sprayed a lot in the distance, but not in the near. rarely spray
[0005] This shortcoming is a great waste of water resources, and the spraying effect is also greatly reduced

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as Figure 1-2 As shown, since the spout is circular, the water flow sprayed by the spout itself has an opening angle of ±2.5° with the axis of the spout.

[0016] According to the actual measurement, the position of the nozzle is A (0.01m, 0.23m)

[0017] Next, calculate the situation when the exit velocity of the nozzle is v=15m / s.

[0018] The situation of the water sprayed from the spout when not modified was simulated, and the range of the landing point was (17.2365, 18.1862), which was in good agreement with the actual spraying situation.

[0019] After modification, the spraying speed can be changed from 5m / s to 15m / s, and the spraying range is (7.11m18.19m).

Abstract

The invention discloses a pulsation reciprocating self-control range lawn nozzle. The nozzle comprises a rocking arm (1), a pressing plate (2), a connecting rod (3), an eccentric shaft (4) and an end cover (5); the pressing plate (2) is fixed at one end of the end cover (5); the bottom of the end cover (5) is fixed in the middle position of the rocking arm (1) through the eccentric shaft (4); and one end of the end cover (5) is fixed on the rocking arm (1) through the connecting rod (3).

Description

technical field [0001] The invention relates to a pulsating reciprocating self-controlled lawn sprinkler, which belongs to the technical field of sprinkler irrigation. Background technique [0002] Sprinkler irrigation refers to an irrigation method that uses special piping systems and equipment to send pressurized water to the irrigation area and spray it into the air to form fine water droplets and sprinkle it on the field. As a new type of irrigation method, sprinkler irrigation has the advantages of saving water, protecting soil structure, regulating the surface climate and not being restricted by terrain, etc. It has been widely used at home and abroad in recent years. At present, there are many problems in the application of this irrigation: due to the long duration and high wind speed of the strong wind in the north, the sprinkler irrigation system cannot operate normally in many cases; except for large green areas such as lawns, other vegetation is irrigated by flood...
