Problems solved by technology

The disadvantage of this method is that the operation is complicated, time-consuming and labor-intensive; it can be used for experimental research, but not suitable for application in production; ② install flow metering devices at the head and branch of the pipeline irrigation system, this method can only control the total water volume of the system, The flow rate cannot be measured for each water outlet of the system; ③ Judging the amount of irrigated water by visually measuring the water level in the border. Although this method can realize the separate treatment of fields, it is not a quantitative technology and is too extensive

Abstract

The invention discloses to a water level control type check irrigation douche and a quantitative check irrigation system and belongs to the technical field of agricultural irrigation. The water level control type check irrigation douche has a floater-connecting rod-conical valve structure; an inner conical valve seat is arranged in a shell between the water inlet and the water outlet of the douche; a connecting rod passes through a valve seat water outlet on the inner conical valve seat; the inner cavity of the shell on the upper part of the water outlet of the douche is provided with a floater; an outer conical valve is fixed at the bottom of the connecting rod; and the floater, the connecting rod and the outer conical valve move up and down together to control the opening and closing of the water level control type check irrigation douche. The douche can precisely control the water level of check irrigation and can be reliably closed. The water level control type check irrigation douche can be connected with the water outlet of a pump or a hydrant of the conventional pipeline water delivery irrigation system to form the quantitative check irrigation system together with a water delivery flexible pipe network. The system can realize quantitative irrigation and can fulfill the aims of no water conveyance loss in fields.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, in particular to a water level control type border irrigation sprinkler and a quantitative border irrigation irrigation system. Background technique [0002] At present, furrow irrigation all utilizes ditches or pipelines to deliver water, and water inlets are excavated in water delivery ditches to allow water flow into the furrow blocks. The traditional border irrigation method will cause water leakage and evaporation loss in the process of channel water delivery, and cannot accurately control the amount of border irrigation water. The water level control type border irrigation emitter is based on the pipeline water delivery, and uses the buoyancy of the water to control the opening and closing of the emitter, so as to realize the quantitative irrigation of the border irrigation. Existing water level controllers use mechanical or electronic methods to control high and low water ...
