Intelligent water-saving water, fertilizer and pesticide integrated irrigation device

Abstract

The invention relates to an intelligent water-saving water, fertilizer and pesticide integrated irrigation device. The top of a tower is provided with a water-sealed casing pipe, the outer wall of thewater-sealed casing pipe is provided with bearings with a bearing sleeve outside, and an outer wall of the bearing sleeve is provided with a large gear which engages with a small gear at an output end of a speed reducer driven by a motor. An upper end of the bearing sleeve is provided with an excessive sleeve pipe which is in approximate contact with the bottom of an upper sleeve pipe of a watersealing sleeve, and a water sealing unit is arranged between an outer pipe wall of the excessive sleeve pipe and an inner pipe wall of the upper sleeve pipe. A rotating frame sleeve pipe is arranged on the bearing pipe, a rotating frame is arranged on the rotating frame sleeve pipe, and the top of the rotating frame sleeve pipe is provided with a pulling frame which is provided with a rotating frame pulling steel rope. The rotating frame is provided with a pesticide delivery pipe which communicates with the rotating frame sleeve pipe and has spraying heads and a water delivery pipe with showerheads, and a water pipe communicates with a lower sleeve pipe. According to the device, water is saved, the water, fertilizer and pesticide integrated irrigation is achieved, the effects of sand control and farmland irrigation are good, and the degree of intelligence is high.

Description

technical field [0001] The invention relates to an irrigation device, in particular to an intelligent water-saving water-fertilizer integrated irrigation device, which is a water-saving irrigation device used in water-deficient areas such as desert control and plateau planting. Background technique [0002] In the north of my country, especially in the northwest region, the problem of soil desertification is serious. With the invasion of wind and sand, a large number of farmlands have become sandy land, and even deserts where vegetation cannot grow. The main reasons for the expansion of desertification are unreasonable human activities, drought and water shortage, sparse vegetation, and wind boosting. The existing method of desert control is mainly to plant trees in the desertified soil to block the wind and stabilize the soil. Due to the shortage of water sources, it cannot be watered in time, the survival rate of the trees is low, and there is a situation of large investm...

Problems solved by technology

[0003] In addition, in some other places in my country, especially in the Northwest Loess Plateau, due to lack of water and rain, crops and vegetation do not grow well due to drought, and a large number of farmlands are not irrigated in time, resulting in low crop yields, and farmers' enthusiasm for growing grain is greatly reduced.

In order to increase their income, farmers often need to lay water pipes in the field, but these water pipes have a short service life, and some hoses will cause soil pollution if they are left in the field. This not only increases the investment cost of farmers, but also is labor-intensive, which seriously restricts agricultural development
