Embodiment Construction

[0008] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0009] See attached figure 1 , 2 According to the present invention, a temperature memory control valve 2 is prefabricated in each water outlet 1 of the emitter, and the lower water stop area of ​​the temperature memory control valve 2 is provided with a water stop protrusion 3 corresponding to the water outlet 1 . The temperature memory control valve 2 of the present invention is made of a shape memory alloy or a polymer memory material, which can be molded into a shape at a certain temperature and return to the original shape at another temperature The shape can be maintained for a long time, and it can be repeated thousands of times without error. Typical shape memory alloys are: NiTi, NiTi-X (X is the third component Cu, Fe) alloys, etc. Cu-based alloys such as CuAlNi, CuAlZn, AuZnSn, etc. have good shap...

Abstract

The present invention discloses an intelligent drip irrigation device capable of utilizing temperature to make automatic regulation, and is characterized by that said invention adopts marmem to make a control valve at water outlet of the irrigation device, and according to the characteristics of requirements of crops for water and fertilizer the valve controller made of marmem can be used for regulating opening and closing state of water outlet of irrigation device and dripping quantity so as to ensure optimum irrigation effect on the premise of saving water.

Description

1. Technical field [0001] The invention belongs to agricultural irrigators, in particular to a temperature self-adjusting micro-irrigation irrigator. 2. Background technology [0002] At present, the water-saving drip irrigation system is realized by pressure water source, head filter, water pipeline, field filter and fertilization, sprinkler or drip irrigation pipe and fully automatic and semi-automatic control facilities. Most of the existing sprinklers adjust the water supply pressure and water output through fully automatic and semi-automatic control facilities to control the main pipe valve. The pressure compensation type emitter only ensures that the water output is basically uniform under different inlet pressures. On-demand drip irrigation in each irrigation area in the field, the current specific method is to embed moisture meters and hygrometers at regular intervals in the field soil, and control the master control valve on the irrigation pipe through sensors to ad...
