Embodiment Construction
[0016] Below in conjunction with accompanying drawing, the present invention will be further described:
[0017] The bait feeder for aquaculture includes a base 1 , a feeding pretreatment device and a mixing box 6 . Wherein the mixing box 6 is in the shape of an upper cylinder and a lower funnel, and two supports 10 are arranged below the mixing box. The base 1 is provided with a bait throwing device; the bait throwing device is provided with a water pump 2, and the water pump is connected with one end of a three-way valve 3, and the other end of the three-way valve is connected with the flushing control valve 4 and the bait flushing pipe 5 all the way. The mixing box 6 is connected, and the lower end of the mixing box is provided with a feeding control valve 7; a feeding pipe 8 is arranged below the feeding control valve 7, and the feeding pipe 8 is connected with the mixing box 9, and a conical nozzle 91 is arranged in the mixing box , Ejector 92, the two ends of the ejecto...

The invention relates to a bait casting machine used for aquaculture. The bait casting machine comprises a base, a feeding pretreatment device and a material mixing box, wherein a bait casting device is arranged on the base; one water pump machine is arranged on the bait casting device, the water pump machine is connected with one end of one three-way valve, the other end of the three-way valve is communicated with the material mixing box by virtue of a flushing control valve and one way of a bait flushing pipe, and a blanking control valve is arranged at the lower end of the material mixing box; a blanking pipe is arranged below the blanking control valve, the blanking pipe is connected with a mixing box, a conical nozzle and an ejector are arranged in the mixing box, and the two ends of the ejector are respectively connected with the conical nozzle and a food provisioning pipeline. When an impact force formed by the conical nozzle is suddenly enlarged when flowing through fracture surface of the ejector, great eddy current is produced, negative pressure in an eddy current region is utilized for pumping bait, and finally the bait is directly put into an aquaculture field by virtue of the food provisioning pipeline.
Description
technical field [0001] The invention relates to a device for aquaculture, in particular to a bait feeder for aquaculture. Background technique [0002] For ricefield eel cage aquaculture farmers, dry and hard bait cannot arouse ricefield eel's desire to eat. So the experts have explored a kind of wet pellet feed with a water content of 25%-50% through scientific practice, and combined the advantages of fresh fish and shrimp (surimi feed) and hard pellet feed. In recent years, wet granule aquatic compound feed has gradually developed from a small amount of promotion and trial to batch use. However, the existing wet pellet feed will quickly spoil and deteriorate during its long-term accumulation process, which will affect the quality and shape of the feed. Secondly, many existing bait conveying devices all use water as the conveying medium, which is undoubtedly "worse" for wet pellet feeds with a water content as high as 25%-50%. [0003] During the transportation process, ...
