Bottom sowing multiplication and capture dual-purpose machine for marine ranching

Abstract

The invention discloses a bottom sowing multiplication and capture dual-purpose machine for a marine ranching. The bottom sowing multiplication and capture dual-purpose machine comprises a fishing boat and a multiplication and capture machine / tool arranged against the fishing boat; the multiplication and capture machine / tool comprises a diesel and water pump unit, a bottom sowing multiplication box, a suction capture pipe, a press-out release pipe as well as a storage and treatment tank; the diesel and water pump unit comprises a diesel and a centrifugal water pump driven by the diesel, and avolute and impeller of the centrifugal water pump are both made of a wear-resistant and corrosion-resistant high-chromium iron material; the lower end of the bottom of the bottom sowing multiplicationbox is uniformly provided with a plurality of sludge paddling rods; and the lower end of the suction capture pipe is provided with three branch suction capture pipes through a transverse communicating pipe. According to the bottom sowing multiplication and capture dual-purpose machine, both bottom sowing multiplication and finished product capture are taken into consideration, so that the mechanical production cost is greatly reduced, and it is convenient to widely popularize and apply the bottom sowing multiplication and capture dual-purpose machine; the bottom sowing multiplication and capture dual-purpose machine is simple in structure, smooth in process, low in labor intensity and high in work efficiency; seedlings for bottom sowing are uniform, and the attachment to the seedlings onthe seabed is good; and finished products are high in capture rate and not easy to damage.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a bottom-sowing dual-purpose machine for multiplication and capture in marine pastures. Background technique [0002] In layman's terms, marine ranching is to use the natural marine ecological environment to gather artificially multiplied and released marine economic organisms, just like grazing cattle and sheep on land, to carry out planned and purposeful management of marine resources such as fish, shrimp, shellfish, and algae. stocking at sea. In recent years, bottom-sowed marine pastures have developed rapidly, especially shellfish bottom-sowed marine pastures have reached a large scale. For bottom-sowing marine pastures, sowing and harvesting are important technical links to achieve high yields. At present, the method of bottom-sowing seedlings for multiplication is still relatively backward. Generally, the whole bag of seedlings is directly poured into shallow sea water manuall...

Problems solved by technology

At present, the method of bottom-sowing seedlings for multiplication is still relatively backward. Generally, the whole bag of seedlings is directly poured into shallow sea water manually. The seedlings drift freely in the seawater, and the seedlings cannot be bottom-sowed to the set area, and it is difficult to achieve multiplication. The purpose of high yield

However, there are two extreme phenomena in the harvesting of finished products. One is to use simple tools such as digging and scratching the soil for manual capture, which is not only labor-intensive, but also has low harvesting efficiency; the other is to use mechanical harvesting, but the structure is complicated and the cost is too high. High, and the finished product is vulnerable to damage, which is not conducive to large-scale application
