Abstract
An adjustable fish sieve, comprise sieve nest and circular screen frame, sieve nest is made up of horizontal grating and longitudinal grating.Circular screen frame both sides are distributed with some holes one to one, even with interval between side cavities; Longitudinal grating is the different semicircular structure of radius, and radius size is successively decreased from centre successively to both sides, and longitudinal grating interval is even, and two ends are fixedly connected on screen frame; Horizontal grating passes the corresponding hole in screen frame both sides and is cross-linked with longitudinal grating, and horizontal grating one end is provided with screw thread, and the other end is provided with the plug being greater than hole aperture.The utility model structure is simple, easy to operate, and the quantity that only need arrange horizontal grating as required can change the size of fish mesh size, effectively large fish and small fish is separated, and greatly reduces the cost that fisherman causes because the fish buying different size is sieved.When certain root grating damages, only the grating damaged need be extracted out, reinsert new grating, easy to maintenance.
Description
Technical field
The utility model relates to technical field of aquaculture, is specifically related to a kind of adjustable fish sieve.
Background technology
At present, when to fry and fingerling magnitude classification, fisherman usually uses fish to sieve and large fish and small fish is distinguished, but it is different with the market demand according to the kind of fish, feeding time length, often make the fish at every turn wanting to fish in different size, the fish sieve of different pore size will be made according to demand, add fisherman's cost.In addition, when not easily changing when damaging appears in the grating of fish sieve, use is delayed.
Utility model content
The purpose of this utility model is: provide one can adjustment aperture according to demand, is convenient for changing the fish sieve of grating.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
An adjustable fish sieve, comprise sieve nest and circular screen frame, sieve nest is made up of horizontal grating and longitudinal grating.Circular screen frame both sides are distributed with some holes one to one, even with interval between side cavities; Longitudinal grating is the different semicircular structure of radius, and radius size is successively decreased from centre successively to both sides, and longitudinal grating interval is even, and two ends are fixedly connected on screen frame; Horizontal grating passes the corresponding hole in screen frame both sides and is cross-linked with longitudinal grating, and horizontal grating one end is provided with screw thread, and the other end is provided with the plug being greater than hole aperture.
By arranging the quantity of horizontal grating, and then regulate the aperture of fish sieve.
Described sieve nest is hemispherical.
Described horizontal grating is made up of elastomeric material.
The beneficial effects of the utility model:
The utility model structure is simple, easy to operate, only need arrange the quantity of horizontal grating and the size of adjustable fish mesh size as required, thus effectively large fish and small fish is separated, and greatly reduces the cost that fisherman causes because of the fish sieve of purchase different size.
When certain root grating damages, only the grating damaged need be extracted out, reinsert new grating, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation after the horizontal grating of adjustment of the present utility model;
Fig. 3 is the A-A face figure of Fig. 2;
Fig. 4 is the structural representation of horizontal grating.
In figure, label 1 is circular screen frame, and 2 is plug, and 3 is nut, and 4 is hole, and 5 is longitudinal grating, and 6 is horizontal grating, and 7 is screw thread.
Embodiment
Embodiment 1: a kind of adjustable fish sieve, as Figure 1-4, comprise sieve nest and circular screen frame, sieve nest is made up of horizontal grating and longitudinal grating.Circular screen frame both sides are distributed with some holes one to one, even with interval between side cavities; Longitudinal grating is the different semicircular structure of radius, and radius size is successively decreased from centre successively to both sides, and longitudinal grating interval is even, and two ends are fixedly connected on screen frame; Horizontal grating passes the corresponding hole in screen frame both sides and is cross-linked with longitudinal grating, and horizontal grating one end is provided with screw thread, and the other end is provided with the plug being greater than hole aperture.
During use, according to required pore size, the quantity of horizontal grating is set.Select the horizontal grating be of convenient length, the hole of the end of thread of horizontal grating from screen frame side is inserted, because horizontal grating is made up of elastomeric material, horizontal grating and longitudinal grating can be cross-linked, guarantee that pore size can not change because of the slip of grating.The plug of horizontal grating one end is stuck in screen frame owing to being greater than the hole of screen frame, and the end of thread of horizontal grating passes from the hole that screen frame opposite side is corresponding, and is fixed on screen frame with nut.Because sieve nest is hemispherical, make to fish for fish in fish sieve due to gravity, can faster large fish and small fish be distinguished.
Claims (4)
1. an adjustable fish sieve, comprise sieve nest and circular screen frame, sieve nest is made up of horizontal grating and longitudinal grating, it is characterized in that: circular screen frame both sides are distributed with some holes one to one, even with interval between side cavities; Longitudinal grating is the different semicircular structure of radius, and radius size is successively decreased from centre successively to both sides, and longitudinal grating interval is even, and two ends are fixedly connected on screen frame; Horizontal grating passes the corresponding hole in screen frame both sides and is cross-linked with longitudinal grating, and horizontal grating one end is provided with screw thread, and the other end is provided with the plug being greater than hole aperture.
2. adjustable fish sieve according to claim 1, is characterized in that: by regulating the quantity of horizontal grating, and then regulates the aperture of fish sieve.
