Description
Technical Field
The invention belongs to the field of shrimp culture, and particularly relates to a method, a control module and a device for feeding bait to a shrimp pond.
Background
According to the '2019 Chinese fishery statistics yearbook', the total yield of freshwater shrimp culture in China is relatively stable in recent years, the total yield of shrimps in 2018 reaches 343.8142 ten thousand tons, and the year-on-year increase is 17.8%. But the research and development and the popularization of the feeding equipment matched with the large culture scale are relatively lagged, the accurate feeding technology for the shrimp pond culture is still a relatively weak link,
in the shrimp pond culture practice, in order to make the feeding of the shrimps regular and thus facilitate the feeding management, continuous feeding areas are arranged in the shallow water area (about 2 m offshore) of the shrimp pond, and feeding is carried out in the feeding areas, so that the shrimps after a period of feeding, develop the habit of taking food in the feeding areas, and the feeding areas are generally called as the 'esophagus' of the shrimp pond.
The artificial bait casting is still the main feeding mode, the bait casting amount is judged according to the experience of farmers, and the farmers throw the feed along the pond, so that the bait casting range is small, the distance is short, the bait casting is uneven, the bait is wasted, and the water quality and the normal growth of shrimps are influenced; the shore-based bait casting machine is adopted or the bait casting machine is directly placed on the bait casting boat, the broken bait is high, the water quality can be polluted, and the bait casting amount can not be accurately controlled. The feeding technology and the performance of the equipment directly influence the breeding environment, the growth of shrimps, the utilization rate of feed, the breeding cost and the like.
The research on the precise bait casting technology at home and abroad mainly focuses on the research on a dosing mechanism, and the commonly used dosing mechanisms comprise a spiral conveying type, a rotary blanking type, an electromagnet suction type, a rotary baffle blanking type and the like. The auger delivery formula is that the parameter according to auger delivery calculates the delivery capacity, realizes quantitative bait casting, nevertheless under pond humid environment, the easy adhesion that agglomerates of fodder, and big, the easy fodder that agglomerates of viscidity can not be carried to this mode, and the broken material height of auger delivery, and spiral and silo are easily worn and torn. The fodder of rotatory unloading formula gets into the unloading intracavity by the feed inlet, the impeller that the motor drove is through rotatory, convey the discharge gate with the fodder by the feed inlet, the angle that the whole process impeller rotated needs to be controlled strictly by the motor, the volume between per two blades of impeller is fixed, when the fodder of needs different weight, as long as control motor rotation angle, just can control and throw the feed volume, the whole focus of this kind of mode is higher, and can not guarantee between the blade that the feed volume that falls into at every turn all is the same, quantitative error is big. The electromagnet is attracted and pulled, the electromagnet is electrified to pull the bin gate baffle plate, so that the feed falls down, when the electromagnet is powered off, the electromagnet and the bin gate baffle plate are pulled back to the original position together by the tension spring to complete interval blanking, continuous blanking can not be realized in the mode, vibration generated by the reciprocating motion of the electromagnet is strong, and the influence on the service life of the electromagnetic coil is large. The rotating baffle blanking formula passes through step motor accurate control feed opening baffle rotation angle, control feed opening aperture and open and close, and then control unloading speed, and this kind of mode feed opening baffle is great with workbin feed opening clearance, and does not study the unloading speed that concrete opening size can reach, can not reach the demand of accurate bait casting.
