Problems solved by technology

[0003] Due to the small size of artificially placed seedlings, the range of activities of small-sized seedlings is small. If the seedlings cannot be accurately placed on the attachment base, the seedlings are easily buried by the sediment at the bottom of the pool washed up by the water flow or fall into the depression at the bottom of the pool. , causing problems such as a decrease in the survival rate
In order to ensure the survival rate of the seedlings, the seedlings need to be accurately placed on the attachment base at the bottom of the water body. The traditional seedling placement generally adopts artificial positioning and splashing, bagging method, and divers dive into the water to play. Among them, the artificial positioning and splashing method is relatively extensive. , the seedlings are often washed away with the surface water flow, and most of the seedlings cannot fall on the attachment base. Although the bagging method can accurately put the seedlings on the attachment base, many seedlings cannot climb out of the net bag. out, and the cost of the mesh bag is high, and it cannot be recycled to pollute the environment; while divers can accurately put the seedlings on the attachment base by diving into the water, but the cost is relatively high
At present, there is no device in the prior art that is simple to operate, low in cost, and capable of accurately releasing seedlings

Abstract

A special device for sowing sea cucumber seedlings at the bottom, belonging to the field of aquaculture devices, the device includes a seed playing funnel, a ventilation pipe, a seedling extension pipe, a seed positioning elbow and a ventilation handle; the seed playing funnel is a funnel The air pipe is a short pipe with a variable diameter tee and two short pipes in a horizontal straight line. The upper end of the air pipe is connected to the small diameter end of the seed playing funnel. Inserting interface, the ventilation handle is a hollow tubular structure, the ventilation handle is vertically connected with the ventilation pipe through the variable diameter insertion interface, the lower end opening of the ventilation pipe is connected with the extension pipe for planting seedlings, and the lower end of the extension pipe for seedlings is connected with the seedling positioning elbow. The device has the advantages of simple operation, accurate positioning, concentrated seed spreading, and high broadcasting efficiency. Good permeability, no wear and tear on seedlings and so on.

Description

technical field [0001] The invention belongs to the field of aquaculture devices, and in particular relates to a special device for bottom-sowing sea cucumber seedlings. Background technique [0002] In natural seas, sea cucumbers generally inhabit rocky reefs, coral reefs or rocky places under the intertidal zone. Among them, the quieter backflow of the reefs and the places where seaweed is overgrown are the best attachment places for sea cucumbers. They not only have abundant benthic bait organisms, but also provide shelter for sea cucumber seedlings from predators. The artificial breeding environment is quite different from the natural environment. In order to simulate the natural environment in which sea cucumbers live, people put sea cucumber special attachment bases in sea cucumber breeding ponds or cofferdams to increase the hidden places for sea cucumbers and improve the habitat of sea cucumbers. Sea cucumber seedlings are used to supplement the shortage of natural ...
