Water tank refrigeration system of agricultural irrigation machine

Abstract

A water tank refrigeration system of an agricultural irrigation machine comprises a water injecting pipe and a water discharging pipe which are arranged on the water tank. A water inlet electromagnetic valve is arranged on the water injecting pipe, a turbine is arranged on the water discharging pipe, and the turbine is connected with a driving motor. A water temperature sensor and a water level sensor are arranged in the water tank. The system further comprises a microcontroller. The water temperature sensor and the water level sensor are connected with the input end of the microcontroller and used f or transmitting the detected water temperature signal and the water level signal in the water tank to the microcontroller. The water inlet electromagnetic valve is connected with the output end of the microcontroller, the driving motor is connected with a relay, and the relay is connected with the output end of the microcontroller. The microcontroller controls the output signals of the water inlet electromagnetic valve and the relay according to the received water temperature signal and the water level signal. The invention automatically injects and discharges water, prevents the scalding accidents caused by manual operations, saves the labour force and reduces the labour strength.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation machines, in particular to a water tank refrigeration system for agricultural irrigation machines. Background technique [0002] Nowadays, large-scale automatic irrigation systems have been used in plain areas, but in most mountainous and hilly areas, the economy is generally backward and most of them use ordinary irrigation machines. This kind of machine will generate a lot of heat when it works for a long time, so that the water in the water tank will heat up quickly, requiring artificial irrigation. Injecting and releasing water can easily cause scalding accidents. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a water tank refrigeration system for agricultural irrigation machines, which realizes automatic filling and drainage, avoids scalding accidents caused by manu...
