Abstract
The invention belongs to the technical field of artificial fish breeding equipment, and particularly relates to a sorting device for sorting fishes in the process of manually breeding fish such as eels, finless eels, loaches and the like and hard fin fishes such as Australian longline spots and the like.
Description
Technical Field
The invention belongs to the technical field of artificial fish breeding equipment, and particularly relates to a selector for selecting fishes with different specifications in the breeding process of fish without scales such as eel, finless eel, loach and the like and fish with hard fins such as Macadimia and the like.
Background
Eel, river eel, belongs to fishes, is similar to snakes, but has no scales, and is generally produced in the sea area with the boundary of salty and fresh water. Eel growth is subject to five periods: the fish eggs, the anguillarum lines, the anguillarum and the anguillarum can be divided into four types of first-stage pools, second-stage pools, third-stage pools and adult anguillarum pools, and the four types of anguillarum pools are respectively used as follows: (1) first-order pool: the eel fry feeding training device is used for eel fry feeding training, and the eel fry is raised to about 3 g, generally the area is 80-100 square meters, the pond depth is 0.8-1.0 meter, and the water depth is 0.3-0.6 meter; (2) a secondary pool: the weight of the breeding eel is 3-20 g, the area is 100-200 square meters, the pool depth is 1-1.2 meters, and the water depth is 0.8-1.0 meters; (3) three-stage pool: eel seeds with the weight of 20-100 g are raised, the area is generally 200-300 square meters, the pond depth is 1-1.2 meters, and the water depth is 0.8-1.0 meters; (4) eel pool: eel seeds with a weight of about 100 g are bred into 170-500 g edible eel, generally 300-500 square meters in area, 1.5-1.6 m in pond depth and 1.0-1.2 m in water depth.
The Australian longline macula belongs to the class of teleostoma, the order of weever, the family of the true weever, the genus of the mackerel, the name of the mackerel, the insect-line snow weever, the ink-line cod and the like, is a famous freshwater economic fish native to the Australian ink-line river basin, and has the characteristics of tender, delicious, thick and less thorn meat, rich amino acids, EPA, DHA nutrient substances and the like, so that the mackerel becomes one of the high-quality fishes cultivated in freshwater in China. During artificial cultivation, the Australian Loongwen spot is cultivated by three-stage fry cultivation method, wherein the first stage is from the open cultivation to the cultivation with the body length of 0.8-3.0cm and the stocking density of 1.0-1.5 kilotails m -2 An area; the second stage has a body length of 3.0-10cm and a stocking density of 0.5-1.0 kilotail.m -2 An area; the third stage has a length of 10-16cm and a stocking density of 0.2-0.5 Kyum -2 Area. Because Australian longling spots are carnivorous fishes, the fries with large size difference can bite into each other to cause a large number of deaths, so that the sorting frequency is once every 15-25 days when the fries are within 50 g/tail weight; the sorting frequency is once every 25-35 days when 50-200 g/tail weight is achieved; the sorting frequency is once every 35-50 days when 200-500 g/tail weight.
According to the method, in the culture process of eel fishes such as eels and the like and weever fishes such as Australian longline spots and the like, the fish with the same specification must be cultured under the same growth environment and the same feeding condition through multiple screening and separate culture because of large growth speed difference and uneven spread, and the weight, specification and mantissa of the fish cultured in the same-stage culture pond are strictly controlled, so that the whole healthy growth of the fish is facilitated. At present, the sorter for screening fish mainly comprises a bamboo sorter, a rattan sorter and a trough sorter, and the three sorters are similar in use when screening fish, namely, fish with different specifications are obtained by limiting the movable space of the fish and matching with artificial water flow, using the turbulent top flow characteristics of the fish, enabling individual smaller fish to swim out from a clearance of a sieve, and transferring the fish shoal left in the sorter to another sorter with different specifications for carrying out the same operation again.
However, the users for breeding eels have the experience that eels are free of scales and fierce in nature, the environment changes after dehydration so that the eels are stressed and struggle easily, the heads of the eels shrink backwards during struggling, the tails of the eels twist forwards, the tail swing amplitude is large and powerful, and the three traditional sorters do not have good design and improvement on the characteristics during fish screening, so that in the actual breeding process, more eels with different specifications are screened each time, and the tail of each eel is twisted around in a lattice of the sorter to cause skin damage of the eels. The separation mode has low separation efficiency, can separate 3-8 tons at most in one day, is easy to cause oxygen deficiency and death loss of fishes in the separation process, is easy to cause damage of the fishes, has large stress degree and reduces disease resistance, thereby causing easy infection of diseases and insect pests and reduction of survival rate in the stage of pond feeding. The similar problems exist in the culture and separation process of finless fishes such as finless eels and loaches and hard fin fishes such as Australian longstriations.
Disclosure of Invention
Therefore, it is necessary to provide a fish sorter to solve the problems of low sorting efficiency, high stress and skin damage and resistance reduction caused by struggling and tail-throwing of the traditional sorter for the non-scaly fishes such as eels, finless eels and loaches, the hard fin fishes such as Australian longstriatum and the like in the sorting process.
In order to achieve the above object, the present inventors provide a fish sorter, comprising a main box, a sorting screen and a fish discharging pipe, wherein the main box is a cuboid or square chamber with an upward opening, the sorting screen is composed of an outer frame and a screen bone, the section of the screen bone is oblong or flat oval, the sorting screen is inlaid and connected in a groove on the upper portion of the main box, and the fish discharging pipe is a through pipe and is fixedly arranged below the middle portion of the main box.
The cross section of the sieve rib is designed into a long ellipse or a flat ellipse, so that the problems of reduction of separation efficiency and skin damage caused by struggling and tail flicking due to exciting reaction in the fish separation process are eliminated, and when fish enters the separating sieve along with water flow diversion, the fish quickly slides into a corresponding regular sieve gap formed by the long ellipse or the flat ellipse sieve rib with radian design, enters a fish discharging pipe and is conveyed to a corresponding classification pool by the fish discharging pipe.
Further, spraying pipes are distributed on the periphery of the top end of the main box body.

Further, the number of the screening sieves is 1-3, and the screening gaps formed by the screening ribs are sequentially embedded and connected in the grooves on the upper part of the main box body from small to large in sequence along the length extending direction of the main box body from the temporary storage pool.
The number of the screening screens is related to the specification of the fish to be screened, if 3 kinds of fishes are to be screened, the number of the screening screens can be 2 or 3, 2 of the 3 screening screens are the same screen slit aperture, the screen slit aperture of the other screening screen is of another specification, and if 4 kinds of fishes are to be screened, the number of the screening screens can be 3, and the screen slit aperture of the screening screens is of 3 specifications.
Further, the fish sorter further comprises a baffle plate, and the size of the baffle plate is the same as that of the outer frame of the sorting screen.
The baffle plate which is matched with the size of the outer frame of the screening sieve is arranged, when the specification of the selected fish is equal to or smaller than 3 kinds, the baffle plate is used for replacing the screening sieve according to the specification of the selected fish, firstly, the buffer effect can be achieved, the stress of the fish in the screening process is reduced, and secondly, the manual efficiency of the screening is improved.
Further, a partition plate capable of moving up and down is arranged between the temporary storage pool and the adjacent sorting screen, and the width dimension of the partition plate is adapted to the width dimension of the main box body.
A partition board capable of moving up and down is arranged between the temporary storage pool and the adjacent sorting screen, and is used for adjusting and controlling the quantity of fish in the temporary storage pool to the sorting screen so as to facilitate personnel sorting. When the amount of the fished fish is large, a large amount of fish can be prevented from flowing into the sorting screen instantly after dehydration through the baffle plate control, and the fish can not be sorted, so that the fish to be sorted are whipped mutually to cause injury or stress general resistance is reduced.
Further, a transmission channel is arranged below the sorting screen, and fishes with the same specification are collected to the fish discharging pipe through the transmission channel.
Due to the effect of spray water during sorting, the water flow is contained in the transmission channel and the fish discharge pipe, under the effect, the fish subjected to rapid sorting can move into the fish discharge pipe under a low stress state and then swim into the corresponding classification pool.
Further, the outer frame is made of stainless steel, the sieve ribs are made of aluminum alloy or stainless steel, and the sieve ribs are fixedly connected with the outer frame through rivets or bolts.
The advantage of this kind of setting lies in the completion of the furthest protection selection fish, and rivet and bolt fastening's mode is convenient for change and maintenance, and the stainless steel material can avoid the corruption that has the water of breeding of salinity, prolongs the life of selection ware.
Further, the aperture of the screening gap of the screening sieve is 3.2-25mm.
The aperture range of the sieve seam fully meets the selection of fishes with different specifications, when the specification difference of the fishes needing to be selected for several times before and after the fishes are larger, the fishes can be selected as evenly as possible by replacing the selection sieve combination.
Further, universal wheels are arranged at the lower end of the main box body, and armrests are arranged at the two ends of the main box body.
The universal wheels and the armrests are arranged, so that farmers can conveniently move the sorting device and set the optimal sorting position according to the needs, and the advantage of the arrangement is that the fish specification sorting can be performed in a mode of least manpower and resources.

The lower part of the temporary storage pool 4 is provided with a drain pipe 33 with the radius of 10cm, the lower part of the sorting screen 2 is provided with a fish discharging pipe 3 with the radius of 10cm, in different embodiments, the fish discharging pipe 3 can be a stainless steel pipe, an aluminum alloy pipe and a PVC pipe with the cross section shape of square, rectangle, ellipse or other regular shapes, the fish discharging pipe extends to the middle lower part of two opposite side walls of the main body box, penetrates the main body box 1 and forms corresponding fish discharging openings 31 on the side walls of the main body box.
Eels are difficult to live after leaving water, are strong in stress, are abnormal in strength, struggle in struggle, and are full of saliva and smooth in the whole body. In order to reduce the stress reaction after eel dehydration, spray pipes 7 are arranged around the top end of the main body box 1, spray ports are uniformly formed in the spray pipes 7, the spray pipes 7 are connected with a water suction pipe in a reservoir through a pipeline on an external hydraulic pump, and spray water is discharged through a water outlet 8 at the lower part of the main box body 1. The shower pipe and the shower water have the advantages that: firstly, the fish to be sorted after fishing is lubricated, so that friction force between the fish and a temporary storage pool, a sorting screen and other fish is reduced; secondly, the fish to be sorted plays a role in guiding flow, so that the fish can move along the sieve gap aperture of the sorting sieve from small to large; thirdly, the wetting of the spray water reduces the mucous secretion of the fish and the stress of the fish.
For conveniently selecting fishes, the positions of the two armrests 5 are adjusted according to the needs, and four universal wheels 6 are arranged at the lower end of the main body box 1 so as to facilitate the movement of the selector.
In the process of culturing eels in the same-stage pond or in different-stage ponds, the eel specification is selected by using the selector, and before the eel specification is selected, all fish discharge ports and water discharge ports are communicated with the corresponding-size culture ponds and reservoirs through pipelines. Firstly, fishing eels from a first-level pond to a temporary storage pond by using a barrel, starting a spray pipe to spray water, controlling the speed and the quantity of the eels flowing through the temporary storage pond and entering a screening sieve by inserting a baffle plate into a baffle plate slot because the eels move fiercely, when the eels enter the first screening sieve, enabling all eels with the specification smaller than 3.2mm (namely 6 towards half) to quickly and smoothly slide into a screening slot of the first screening sieve to enter a fish discharge pipe through a transmission channel, then collecting the eels to a fish discharge port to slide into a culture pond with the corresponding specification, enabling the other eels to enter the next screening sieve, enabling all eels with the specification smaller than 3.5mm (7 towards half) to quickly and smoothly slide into a screening slot of the second screening sieve to enter a fish discharge pipe through the transmission channel, and collecting the eels to slide into a culture pond with the corresponding specification, enabling the eels with the aperture smaller than 4.0mm (7 towards half) to be quickly and smoothly slid into a culture pond with the specification of the fourth type 8 towards above after the last screening sieve, and not sliding into the discharge pipe, so that the eels can be cultured into different levels.
In different application embodiments, if the specification of the fish to be screened is larger (more than 8 towards half) and 4.5mm, the whole screening group is replaced by a screening group with larger screen slit aperture, for example, the screening group with the screen slit aperture of 5mm (8 towards half), 5.5mm (9 towards half) and 7mm (10 towards half) or the screening group with the screen slit aperture of 8mm (10 towards half), 9.5mm (11 towards half) and 12mm (12 towards half) or the screening group with the screen slit aperture of 12.5mm (12 towards half), 13mm (3 inches), 13.5mm (3 inches half) and larger size combination are replaced, and the proper screening combination can be selected according to the specification difference of the fish to be screened.
The fish sorter can also be used for pond culture of loaches, finless eels and Australian longstriations or grading screening before marketing, and if the fish sorter is used for marketing screening before marketing, the fish sorting device only needs to connect a fish discharging port with a fish storage box special for transportation, is convenient to operate, does not need manual secondary transportation, and saves manpower and material resources.
The equipment has the beneficial effects that the screening sieve with different sieve seam aperture specifications is formed by adopting a plurality of oblong or flat oblong sieve bones and the stainless steel outer frame, the fish without the tail and broken skin are screened in the screening process, and the spray water device is arranged at the top of the screening device, so that the fish is screened in the spray water state, the fish body is sufficiently lubricated, guided and reduced in stress, the disease resistance of the fish is improved, the risk of disease infection of the fish body cultivated in the separate pond after screening is reduced, and the fish with 4 specifications can be simultaneously screened, 20 tons can be screened at most in one day, the screening efficiency is greatly improved, the manual labor amount is reduced, and the number of the fish with oxygen deficiency death is reduced.
It should be noted that, although the foregoing embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concepts of the present invention, alterations and modifications to the embodiments described herein, or equivalent structures or equivalent flow transformations made by the present description and drawings, apply the above technical solution, directly or indirectly, to other relevant technical fields, all of which are included in the scope of the invention.
