Flexible variable-arm long rotary sprinkling machine

Abstract

The invention relates to a flexible variable-arm long rotary sprinkling machine, comprising a base, wherein, the base is sheathed with a box body; the box body is internally equipped with a main motor for driving a central spindle to rotate; the central spindle is internally equipped with a water pipe; an upper end and a lower end of the central spindle are connected with rotary joints, the lower end is connected with a water hose, and the upper end is connected with a diversion turntable; one end of an articulated retractable truss is articulated with the diversion turntable, the other end thereof is articulated with an adjusting block which can move up and down, and a sprinkling hose is fixedly wound at the articulated position in the middle-lower part of the truss; the center of the diversion turntable is fixed with an electric motor, the output shaft of the electric motor keeps upward, the upper side thereof is sheathed with an adjusting block, and the adjusting block is articulated with one end of an innermost rod piece of the truss; and the opening of a rotary truss is changed by up-and-down motion of the adjustment block so as to realize stretching or contracting of the rotary truss. The rotary sprinkling machine can meet the irrigation demands with different heights and different irrigation areas; and according to the need, the section number of the truss can be conveniently increased and decreased to improve the rationality of resource utilization.

Description

technical field [0001] The invention belongs to a sprinkler irrigation machine in the field of agriculture, and in particular relates to a flexible variable arm length rotary sprinkler irrigation machine. Background technique [0002] Micro-sprinkler irrigation is a method of irrigating by atomizing the water column into tiny water droplets through a micro-spray head or a micro-spray belt. It has the advantages of not being easy to block and less water consumption in drip irrigation, and overcomes some of the shortcomings of both of them. Due to the large outlet hole of the micro-spray head, although the working pressure is similar to that of drip irrigation, its flow rate is fast, which reduces the possibility of clogging, and the flow rate is also large. A single area can be sprayed, so the material used per mu is less than that of drip irrigation, saving energy. cost. Therefore, it has been widely used in the irrigation of large-scale crops in recent years. [0003] The...

AI Technical Summary

Problems solved by technology

[0006] Most of the current external-use sprinkler irrigation machines can only be exposed to harsh natural environments because their booms cannot be retracted or can not be greatly retracted, which greatly reduces the service life
