Shrimp pond bait feeding method, control module and device

Abstract

The invention belongs to the field of shrimp culture, and discloses a shrimp pond bait feeding method. The feeding method can realize uniform and accurate bait feeding in a shrimp pond, monitors whether the real-time discharging and feeding speed on a feeding path is equal to the expected discharging and feeding speed or not, and adjusts the real-time discharging and feeding speed to the preset discharging and feeding speed if the real-time discharging and feeding speed is not equal to the expected discharging and feeding speed. The invention further discloses a shrimp pond bait feeding control module and device, in particular to a shrimp pond bait feeding device. The shrimp pond bait feeding method can be well and automatically implemented, the structure is simple, use is convenient, the shrimp pond bait feeding device is arranged on a catamaran and comprises a connecting assembly, a bait feeding unit and a bait feeding control module, the bait feeding unit comprises a bait box, an electric push rod and an opening plate, the bottom of the bait box is of a bucket-shaped structure, a bait feeding opening is formed in the bottommost part of the bait box, the electric push rod is arranged on the outer surface of the bottom of the bait box, and when the electric push rod acts, the opening plate closes or opens the bait feeding opening.

Description

technical field [0001] The invention belongs to the field of shrimp farming, and in particular relates to a method for feeding shrimp pond bait, a control module and a device. Background technique [0002] According to the "2019 China Fishery Statistical Yearbook", in recent years, the proportion of my country's total freshwater shrimp farming output has been relatively stable. In 2018, the total shrimp output reached 3,438,142 tons, a year-on-year increase of 17.8%. However, the research and development and promotion of baiting equipment for large-scale farming are relatively lagging behind, and the precision baiting technology for shrimp pond farming is still a relatively weak link. [0003] In the practice of shrimp pond farming, in order to make the feeding of shrimp regular and easy for feeding and management, the farmers set up continuous feeding areas in the shallow water area of ​​the shrimp ponds (about 2 meters offshore), and set up continuous feeding areas in the ...

AI Technical Summary

Problems solved by technology

The screw conveying type calculates the conveying amount according to the parameters of the screw conveyor, and realizes quantitative feeding. However, in the humid environment of the pond, the feed is easy to agglomerate and stick. This method cannot convey the viscous and easily agglomerated feed. The material is high, the screw and the trough are easy to wear

The feed of the rotary feeding type enters the feeding chamber from the feeding port, and the impeller driven by the motor rotates to transfer the feed from the feeding port to the discharging port. The volume between the two blades is fixed. When different weights of feed are needed, the amount of feed can be controlled by controlling the rotation angle of the motor. This method has a higher overall center of gravity and cannot guarantee the amount of feed that falls between the blades every time. The amount is the same, the quantitative error is large

The electromagnet suction pull type is powered by the electromagnet to pull the material door baffle to make the feed fall. When the electromagnet is powered off, the tension spring pulls the electromagnet and the material door baffle back to the original position together to complete the interval feeding. This method cannot realize continuous feeding, and the vibration generated by the reciprocating motion of the electromagnet is relatively strong, which has a great impact on the service life of the electromagnetic coil

The rotary baffle feeding type precisely controls the rotation angle of the feeding port baffle through the stepping motor, controls the opening of the feeding port and its opening and closing, and then controls the feeding speed. The gap is large, and there is no research on the feeding speed that can be achieved by the specific opening size, which cannot meet the needs of accurate baiting

[0006] In summary, among the currently known bait feeding methods in shrimp ponds, there is no feeding method that can solve the problem of uniform and accurate bait feeding in shrimp ponds
