Semi-automatic bottom sowing device

Abstract

The invention relates to a semi-automatic bottom sowing device comprising a cabin outlet machine and a slide groove. The slide groove is mounted slantwise, one end of the slide groove is fixed at a hatchway through a hook, and the other end thereof extends out of a ship body; the cabin outlet machine is vertically mounted in a cabin, and is fixed at the hatch through a fixing frame; a flexible folding supporting frame is fixed on a chain; a seed box is arranged on a loading table at the bottom part of a bracket of the cabin outlet machine or directly arranged on the supporting frame; and a motor rotates to drive a drive shaft to rotate, the drive shaft drives the supporting frame through a drive gear and the chain to support the seed box to move upwards to the hatchway, workers drag the seed box into the slide groove to pour a seed stop lever out, and the seed stop lever stops the seed box from sliding along a groove body, and seeds are dashed out the slide groove to scatter in a bottom sowing water area under the action of water current impulsive force of a water spray hole of a wash pipe. The semi-automatic bottom sowing device can improve the seeding uniformity of scallop seeds, reduces the death and injury rate of the scallop seeds, reduces the labor intensity of workers, reduces the labor cost, greatly improves the operation safety, and realizes the mechanization of marine seed sowing machines.

Description

technical field [0001] The invention relates to a bottom sowing device, in particular to a semi-automatic bottom sowing device for bottom sowing scallop seedlings. Background technique [0002] At present, in the coastal areas of our country, the cultivation of scallops is developing rapidly, and the breeding of scallops is a fast-growing and effective breeding method that has emerged in recent years. It has small investment, easy management, and has the advantages of large-scale breeding development. The development potential is huge. The survival rate of scallop seedlings has a great impact on the yield of scallops. According to investigations, in the traditional artificial seedling operation, the water in the cabin is first emptied, and then the seedlings are manually transported from the bottom of the bilge to the deck, and then spread to the bottom. In the sowing water area, there are the following disadvantages in the current operation method: [0003] 1. The scallop...

AI Technical Summary

Problems solved by technology

[0003] 1. Uneven distribution of scallop seedlings

The scallop seedlings are packed in boxes and piled up in the cabin. The seedling boxes near the hatch are easy to carry and spread quickly, while the seedling boxes at the bottom of the bilge need to be lifted by workers to the hatch with ropes for spreading, which causes scallop seedlings to spread Uneven density, the situation of more in the front and less in the back

[0004] 2. The death rate of scallop seedlings is high

The season for sowing scallop seedlings is November every year. The sea is very windy and the waves are strong. Workers cannot stand stably during operation, and it is extremely easy to trample on the scallop seedlings. Especially the scallop seedlings at the bottom of the cabin need to be lifted by hands or hung by ropes. Transport it out of the cabin, during this process the seedling box is very easy to fall, killing and injuring the scallop seedlings

Moreover, the long-term dry dew of the seedlings will increase the mortality rate of the seedlings.

[0005] 3. The labor intensity of the workers is high

When the scallop seedlings are sown to the bottom of the ship, the workers need to lift the scallop seedling boxes out of the cabin by hand or rope. The labor intensity of the workers is high, the working hours are long, and the number of workers is large.

[0006] 4. Poor operation safety

When the scallop seedlings are sown to the bottom of the cabin, the workers on the deck need to use ropes to lift the scallop seedling boxes at the bottom of the cabin to the deck. During the process of lifting the boxes, the ropes are likely to be loose and the seedling boxes may hurt the workers in the cabin.
