Retractable type water, fertilizer and pesticide integrated spraying irrigation equipment

Abstract

The invention discloses retractable type water, fertilizer and pesticide integrated spraying irrigation equipment. The equipment comprises a casing pipe, a first-stage retractable pipe, a second-stageretractable pipe and a nozzle which sequentially sleeve one another from outside to inside, wherein the nozzle is disposed on the top of the second-stage retractable pipe; the bottom of the casing pipe is communicated with a water pump through a base and a connecting pipe which are in screwed connection; feeding through holes are formed in the portions, symmetric about the central axes of pipe bodies, of the interiors of the pipe bodies of the casing pipe, first-stage retractable pipe and second-stage retractable pipe respectively; the portions, located at end openings of the feeding throughholes, of the casing pipe and an inner cavity of the top of the first-stage retractable pipe are fixedly connected with hemispherical connectors, and every two adjacent feeding through holes are communicated with each other through the corresponding hemispherical connector. A controller is adopted for controlling the water pump and a pesticide pump to work, liquid which is pumped out is mixed by apesticide mixing device and then sprayed out through the nozzle, and integrated spraying of water, fertilizer and pesticide can be realized.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to telescopic water, fertilizer and medicine integrated sprinkler irrigation equipment. Background technique [0002] The existing buried sprinkler irrigation equipment is composed of multi-section pipe sleeves and telescopic pipes. Water is injected into the pipe sleeves through a water pump, and the multi-section pipe sleeves and telescopic pipes are ejected from the ground, and then reset by siphon away. [0003] The prior art application number CN201310006949.8 discloses a buried automatic telescopic integrated sprinkler irrigation equipment, which is connected to a water delivery pipeline. It is characterized in that the sprinkler irrigation equipment includes casings, The primary telescopic pipe and the secondary telescopic pipe, as well as the lifting nozzle, the bypass branch pipe and the spring; the casing is buried under the ground, and the casing is connected to the wa...
