A telescopic sprinkler device for a large sprinkling irrigation machine

Abstract

The invention discloses a telescopic water spray device for a large sprinkler irrigation machine, which belongs to the technical field of irrigation. The water spray device includes: telescopic tube, weight tube, locking mechanism, outer wire nozzle interface. The telescopic tube is tightly fitted inside the weight tube and can slide axially relative to the weight tube; the upper end of the telescopic tube outside the weight tube is connected to the water delivery pipe of the large sprinkler irrigation machine; the lower end of the weight tube is connected to the outer wire nozzle connection; the locking mechanism includes an elastic piece and a locking piece, the elastic piece is tightly fitted on the outside of the telescopic tube body, and slides along the axial direction of the telescopic tube, and a wedge-shaped hole is set at the lower part; the locking piece is fixed on the upper end of the weight tube, and The upper part is provided with wedge-shaped blocks, and the wedge-shaped blocks and the wedge-shaped holes are arranged in an inverted structure to offset and cooperate; when the telescopic tube is stretched, the wedge-shaped blocks are separated from the wedge-shaped holes; The water spray device of the present invention enables the height of the spray head to be adjusted from the ground, and ensures that the spray head is always vertically downward, and the spray irrigation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a telescopic water spray device for a large sprinkler irrigation machine. Background technique [0002] Large-scale sprinkler irrigation is an important large-scale water-saving irrigation equipment for farmland. It has the advantages of water saving, labor saving, and high automation. It is of great significance for the promotion of energy-saving irrigation. During use, the water delivery pipe of the large-scale sprinkler is usually connected with a matching sprinkler device, and a sprinkler head is connected to the sprinkler at the same time, so as to realize the sprinkler irrigation function of the large-scale sprinkler. [0003] The sprinkler device provided by the prior art usually includes a fixed sprinkler pipe, the lower end of which is provided with a nozzle interface for connecting the sprinkler head, and the upper end of the fixed sprinkler pipe is connected to the ...

AI Technical Summary

Problems solved by technology

And for different crops and different growth stages of the same kind of crops, its corresponding heights are all different, using the water spray device provided by the prior art will bring a lot of inconvenience

In addition, the sprinkler device provided by the prior art cannot ensure that the sprinkler head is always vertically downward, and these problems are likely to reduce the efficiency of sprinkler irrigation
