Abstract

The invention discloses a valved resonant piezoelectric pump for agricultural sprinkling irrigation, and relates to a device for conveying fluid in an agricultural irrigation system. The device is composed of a piezoelectric vibrator, an upper vibration transmission block, an upper vibration transmission elastic piece, a lower vibration transmission block, a lower vibration transmission elastic piece, a diaphragm, a wheel type valve and the like. According to the valved resonant piezoelectric pump for agricultural sprinkling irrigation, the piezoelectric vibrator is connected with an alternating current power supply and is driven by electric signals with different waveforms, so that the resonance system is driven to enable the amplitude of the piezoelectric vibrator to be amplified through a vibration transmission rod and act on the diaphragm, and directional conveying of fluid in the pump cavity is achieved; and a piezoelectric actuator is separated from the pump cavity diaphragm, the pump cavity diaphragm is driven after the displacement of the piezoelectric actuator is amplified according to the resonance principle, high-efficiency pumping can be completed even under the condition that the fluid height difference is large, and agricultural sprinkling is facilitated.

Description

technical field [0001] The invention belongs to the field of fluid transportation, and in particular relates to a device for fluid transportation in an agricultural irrigation system. Background technique [0002] Piezoelectric pump is a fluid delivery device with piezoelectric vibrator as the driving force source. It has the advantages of small size, low power consumption, low cost, no electromagnetic interference, and precise flow control. It is widely used in biomedicine, precision chemistry, micro-electromechanical engineering Such collars are widely used, but piezoelectric pumps are less used in agriculture. [0003] The improvement and application of irrigation system in traditional agriculture is not in place, resulting in a lot of waste of water resources, and the continuous increase of irrigation costs, which is not conducive to the conservation of water resources and the improvement of farmers' harvest. The invention proposes a valved resonant piezoelectric pump f...
