Problems solved by technology

The timely and appropriate screening of seedlings has a great impact on the survival rate and yield of scallop cultivation. Traditional scallop seedling screening uses manual operations, with a large number of operators and low work efficiency, and manual operations are extremely labor-intensive and high. Intensive and long-term seedling screening operations make it difficult to guarantee the quality of seedling screening; on the other hand, seedlings are easily damaged in the work of scooping and fishing, and the seedling damage rate is extremely high
The traditional seed screening method seriously restricts the industrialization and regulation of scallop farming.

Embodiment 1

[0023] Screen scallop seedlings collected from natural sea areas, and collect scallop seedlings above 0.3cm in size.

[0024] Such as figure 1 with figure 2 As shown, the scallop seed screening device includes a power unit 1, a frequency conversion device 2, an eccentric crank arm mechanism 3, a connecting rod 4, an adjustment support 5, a body 6, a body support 7, a seedling feeding groove 8, a screen support 9, Spray pipe 10, partition 11, primary screen 12, secondary screen 13, primary screen collection box 14, collection box discharge port 15, secondary screen storage box 16, storage box discharge port 17, seed collection Groove 18 and overflow port 19. Wherein, the body support 7 supports the body 6, and the top of the body 6 one end is provided with a seedling feeding groove 8, and the seedling feeding groove 8 is connected with the body 6 by adjusting the support 5, and by adjusting the support 6, the height and height of the seedling feeding groove 8 apart from the ...

Embodiment 2

[0028] Screen the scallop seedlings bred in the middle, and screen the seedlings with a size of 0.3cm to 0.5cm and above 0.5cm.

[0029] The structure of the seedling screening machine is as follows: figure 1 with figure 2As shown, the filter screen 20 is not erected, and the rest are the same as in Embodiment 1. The screen support 9 is placed inside the body 6 and remains relatively independent from the body 6 along the horizontal direction, and the inclination angle is 5°. According to the screening requirements, the primary screen 12 selects a screen with a mesh opening of 0.3cm, and the secondary screen 13 selects a screen with a mesh of 0.5cm, and the primary screen 12 and the secondary screen 13 are laid on the screen support 9 On, start the power unit 1 and the water spray pipe 10, adjust the frequency conversion device 2 to control the inclined reciprocating speed of the screen support 9, put the scallop seed into the seedling groove 8, and the water flow of the wate...

Abstract

The invention relates to the field of aquaculture, in particular to a device for screening scallop seedlings. The device for screening the scallop seedlings comprises a power device, a frequency conversion device, an eccentric crank arm mechanism, a connecting rod, an adjusting support, a machine body, a machine body support, a seedling feeding tank, a screen support, a water spraying pipe, a barrier, a primary screen, a secondary screen, a primary screen collection box, a collection box discharge outlet, a secondary screen storage box, a storage box discharge outlet, a seedling collection tank and an overflow port. In the invention, a mechanical device is used for substituting the traditional manual seedling screening operation, so that a large amount of labor force is saved, the labor intensity of employees is greatly reduced, and the work efficiency is greatly improved at the same time; moreover, the whole process of the screening of scallop seedlings is performed in water in the operation process, so the survival rate of the seedlings is ensured, and the screened seedlings have good quality and consistent specification; and seedling washing and screening are finished at one time, the operation link of seedling washing is saved, and pollution can be removed and two grades of scallop seedlings can be sorted through once-through operation.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a scallop seed screening device. Background technique [0002] At present, in the coastal areas of my country, shellfish farming such as scallops is developing very rapidly. Whether it is artificial seedlings or natural seedlings, the screening process of shellfish seedlings is very important. The timely and appropriate screening of seedlings has a great impact on the survival rate and yield of scallop cultivation. Traditional scallop seedling screening uses manual operations, with a large number of operators and low work efficiency, and manual operations are extremely labor-intensive and high. Intensive and long-term seedling screening operations make it difficult to guarantee the quality of seedling screening; on the other hand, seedlings are easily damaged in the work of scooping and fishing, and the damage rate of seedlings is extremely high. The traditional seed screening method ...
