Description

Automatic control system for vibrator of fishpond feeding machine Technical Field The invention relates to the technical field of vibrator automatic control, in particular to an automatic vibrator control system for a fishpond batch feeder. Background In the process of fish and shrimp cultivation, a feeding machine is required to be arranged beside a fish pond for feeding the fish and the shrimp with feed. The pond feeder typically requires that the feed be evenly delivered from a storage bin or hopper to the feed inlet. Since feed pellets may accumulate or clog due to friction, resting state or other factors, the vibrator may loosen the feed and maintain fluidity by high frequency vibration, avoiding clogging, in particular by controlling the amplitude of the vibrator to control the feed rate. The vibration amplitude of the vibrator on the current market needs to be manually adjusted through an adjusting knob, when the power supply voltage is reduced in the peak period in the daytime, the vibration amplitude can be obviously reduced, so that the feed is insufficient to feed, the growth of fishes and shrimps is affected, when the power supply voltage is increased in the valley period at night, the vibration amplitude can be obviously increased, the abnormal vibration condition of the vibrator is caused, the feed is wasted, and even the vibrator is damaged. In these cases, personnel are required to manually adjust the vibration amplitude through the knob, the personnel are required to go to patrol at regular time, the manpower is wasted, and if the patrol is not performed, the vibrator can be damaged, or the feed is wasted or the fish and shrimp are insufficient in nutrition.
