Description

Fry collecting device for industrial breeding of pike

Technical Field

The utility model relates to an aquaculture technical field, concretely relates to fry collection device that pike batch production was grown seedlings.

Background

Mullets, also known as "meat sticks" and "pinkish red-eye mullets", are precious species of freshwater-saltwater aquaculture in china coastal areas. The head of the pike is short and wide, and the scales are large. The back of the pike is grey, the ventral surface is light grey, and the scales on the two sides have black vertical lines. The mullets live in coastal mouths and rivers or in salt water. The pike likes the colony life and takes the organic matters in the soil at the bottom of the water as food.

The application range of the pike to salt is 0-38 per mill, and the pike can survive in seawater, salty fresh water and inland river fresh water lakes. The mullet can normally inhabit and forage in a water area with the water temperature of 3-35 ℃, and death occurs when the water temperature is optimally 12-25 ℃ and is lower than-0.7 ℃.

The mullet is rich in protein, fatty acid, vitamin B, vitamin E, calcium, magnesium, selenium and other nutrient elements, rich in unsaturated fatty acid, beneficial to blood circulation and good for cardiovascular patients.

When fry collecting time is long, labor intensity of workers can be reduced through the auxiliary connecting piece 201, and fry in a plurality of breeding ponds can be collected simultaneously.

Example 2:

in this embodiment, a support frame is added to embodiment 1 as shown in fig. 3. The support frame includes base 308, sets up vaulting pole 307 and the carousel 304 in base 308 department perpendicularly, carousel 304 rotates with vaulting pole 307 to be connected, carousel 304 department equipartition has a plurality of calorie holes 305 that are used for joint retainer plate 101.

The existence of support frame makes to collect the fry in the great and more reproduction pond of fry mantissa of cell body more convenient more.

Specifically, a supporting rod 307 is vertically arranged at a base 308 of the supporting frame, a flange for supporting the turntable 304 is arranged at an outer wall of the supporting rod 307, and the turntable 304 is rotatably connected with the supporting rod 307 through a mounting hole arranged at the center. Several chucking holes 305 at the turntable 304 are used to chuck the collection mesh of example 1. The snap holes 305 are spaced along the center of the disk 304 so that the drain ports align with the collection screen as the disk 304 rotates.

When the device is used, the support frame is placed at the water outlet of the breeding pond, the position of the support frame is adjusted to enable each clamping hole 305 to be aligned with the water outlet, and a collecting net is placed at each clamping hole 305. Then, the drain opening is opened, and when the collection net below the drain opening is fully collected, the turntable 304 is rotated to align the drain opening with the next collection net. Therefore, uninterrupted collection of the fry can be achieved, and work efficiency is improved.

In this embodiment, the upper surface of the turntable 304 is provided with a first annular guard edge 301 and a second annular guard edge 302, and each of the card holes 305 is located between the first annular guard edge 301 and the second annular guard edge 302. Fry can be prevented from being scattered to the outside when the collection net is switched by the first annular guard edge 301 and the second annular guard edge 302.

In this embodiment, as shown in fig. 4 to 5, a positioning element is disposed on the surface of the turntable 304, the positioning element includes a mounting seat 303, a spring 311, a positioning bead 310 and a fixing block 309, second slots 306 having the same number as the number of the locking holes 305 at the turntable 304 are uniformly distributed at the outer wall of the supporting rod 307, the mounting seat 303 is fixedly connected to the turntable 304, a cavity for accommodating the spring 311 and the positioning bead 310 is disposed in the mounting seat 303, a through hole 312 for partially exposing the positioning bead 310 is disposed at one end of the mounting seat 303 close to the supporting rod 307, and the spring 311 and the positioning bead 310 are disposed in the cavity through the fixing block 309.

The positioning element is fixedly connected to the upper surface of the turntable 304, the axis of the positioning element coincides with the radial direction of the turntable 304, and one side of the positioning element, which is close to the stay bar 307, is flush with the tangent plane of the mounting hole at the center of the turntable 304. The mounting base 303 is provided with a cavity for accommodating the spring 311 and the positioning ball 310 therein, one end of the mounting base 303 close to the stay 307 is provided with a through hole 312 for partially exposing the positioning ball 310 outside, and the spring 311 and the positioning ball 310 are fixed in the cavity through the fixing block 309.

When the water collecting device is used, the spring 311 provides elastic force, the positioning ball 310 exposed outside the mounting seat 303 is matched with the second clamping grooves 306 uniformly distributed at the outer wall of the supporting rod 307, namely, when the positioning ball 310 is clamped into any one of the second clamping grooves 306, the water outlet is just aligned with the collecting net arranged at the rotating disc 304. When the collection net needs to be switched, a worker applies an external force to rotate the rotary disc 304, and when the positioning ball 310 is clamped into the next second clamping groove 306 along with the rotation of the rotary disc 304, the rotary disc 304 stops rotating due to the acting force of the second clamping groove 306 on the positioning ball 310 or the force feeling of the worker rotating the rotary disc 304. Therefore, accurate positioning of the collection screen and the drain port at the turntable 304 can be achieved.

In this embodiment, an inner thread is disposed on an inner wall of the cavity, and an outer thread adapted to the inner thread is disposed on an outer wall of the fixing block 309.
