Abstract
Description
Technical Field
[0001] This application pertains to the field of aquaculture. Background Technology
[0002] Traditional aquatic feed domestication cages, especially traditional mandarin fish feed domestication cages, are commonly fixed with floating bridges (buoys) on the four sides at the top and tied to bricks and stones at the four corners at the bottom. The bricks and stones are then sunk to the bottom of the water to form a cage. Multiple cages are connected in series to form a breeding area, and the operation is carried out manually on the floating bridge.
[0003] However, traditional aquatic feed domestication net cages have poor sludge formation, easily trapping fish or creating stagnant water and low dissolved oxygen areas, which affect the growth and development of mandarin fish.
[0004] Therefore, how to improve the effect of bagging has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, this utility model provides a device for feeding and domesticating mandarin fish, comprising:
[0006] The net bag includes a bag opening and a bag bottom. The bag opening is connected to the column frame, and the bag bottom is connected to the horizontal pull member. The horizontal pull member is adapted to be fixed at both ends to opposite side walls of the pool. The bottom of the column frame is fixed to the bottom surface of the pool.
[0007] Optionally, the horizontal tension member includes a steel cable.
[0008] Optionally, the column frame includes uprights and horizontal beams, with the horizontal beams fixedly connected to each of the uprights.
[0009] Optionally, the bottom of the horizontal tie member is half a meter above the bottom of the pool.
[0010] Optionally, the bag opening is connected to the columnar frame, and the bag bottom is connected to the horizontal pull member, including: tying ropes are arranged on each side of the bag opening and the bag bottom, and the tying ropes are connected to the columnar frame or the horizontal pull member.
[0011] Optionally, it further includes: a horizontal plate and a horizontal support, the horizontal support being fixedly connected to the column frame for supporting the horizontal plate, the horizontal plate being located between the horizontal tie and the top of the column frame.
[0012] Optionally, the top of the column frame is half a meter higher than the horizontal plate, and the horizontal plate is adapted to be flush with the water surface.
[0013] Thus, the device for feeding and acclimatizing mandarin fish provided by this utility model, through a columnar frame fixed to the bottom and horizontal pullers fixed at both ends, connects the bag opening and the bag bottom respectively, thereby fully stretching and fixing the net bag, resulting in a good catching effect. This avoids the net bag twisting and trapping aquatic organisms due to water floating or aquatic movement, thereby improving the survival rate of feed-acclimatized aquatic organisms. Secondly, while increasing the space utilization efficiency of the device and increasing the stocking density, the water inside the net bag can be fully exchanged with the outside water, maintaining good water quality inside the net bag, which is conducive to the growth and development of aquatic organisms. It can be seen that the device for feeding and acclimatizing mandarin fish provided by this utility model can improve the catching effect. Attached Figure Description
[0014] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of this application. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.
[0015] Figure 1 A schematic diagram of a device for feeding and domesticating mandarin fish according to this utility model. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a device for feeding and acclimatizing mandarin fish, provided by this utility model. Figure 1 As shown, the device for feeding and acclimatizing mandarin fish provided by this utility model includes: a net bag 1, a columnar frame 2, and a horizontal tension member 3. The net bag 1 includes a bag opening 11 and a bag bottom 12. The bag opening 11 is connected to the columnar frame, and the bag bottom 12 is connected to the horizontal tension member 3. The horizontal tension member 3 is adapted to be fixed at both ends to opposite side walls of the pool. The bottom of the columnar frame is fixed to the bottom surface 4 of the pool. It is worth noting that, in order to fully stretch and expand the fixed net bag 1, the size of the net bag 1 itself is adapted to the distance from the top of the columnar frame 2 to the horizontal tension member 3 and the size of the columnar frame 2.
[0018] The column frame 2 includes prisms and cylinders. The prisms include triangular prisms, quadrangular prisms, and other prisms. When the number of lateral edges is large, it can be regarded as a cylinder. In some embodiments, the column frame 2 includes a column 21 and a horizontal beam 22. The bottom end of the column is fixed to the bottom surface, and the top end is fixed to the horizontal beam. In this case, the bag opening 11 can be connected to either the column 21 or the horizontal beam 22, or it can be connected to the connection point of the column 21 and the horizontal beam 22, that is, the vertex of the prism. It is worth noting that in some embodiments, the column frame 2 may only include the column 21 fixed to the bottom surface. In this case, the bag opening 11 is fixedly connected to the column 21, which can also support and fix the mesh bag 1. The bag opening 11 is connected to the column frame 2, or the bag bottom 12 is connected to the horizontal tie 3. In some embodiments, the bag opening 11 and the bag bottom 12 may be provided with binding ropes on each side, and the column frame 2 or the horizontal tie 3 may be connected by binding ropes.
[0019] The horizontal tension member 3 is horizontally fixed and used to provide a fulcrum to tighten and fix the horizontal bar or steel cable of the bag bottom 12. When it is a steel cable, in some embodiments, the two ends of the steel cable can be fixedly connected to the side wall of the pool body to tighten and fix the steel cable; in other embodiments, the two ends of the steel cable can be fixedly connected to the column frame 2.
[0020] In some embodiments, the uprights 21 of the column frame 2 are directly welded to the bottom surface of the pool and fixed in the feed acclimatization pool. In other embodiments, the column frame 2 can stand on the bottom surface of the pool by its weight and can also be fixed in the feed acclimatization pool.
[0021] Thus, the device for feeding and acclimatizing mandarin fish provided by this utility model, through a columnar frame 2 fixed to the bottom surface and horizontal pullers 3 fixed at both ends, connects the bag opening 11 and the bag bottom 12 respectively, thereby fully stretching and expanding the fixed net bag, resulting in a good catching effect. This avoids the net bag from twisting and wrapping the aquatic products due to water floating or aquatic movement, thereby improving the survival rate of feed-acclimatized aquatic products. Secondly, while increasing the space utilization efficiency of the device and increasing the stocking density, the water inside the net bag can be fully exchanged with the outside water, maintaining good water quality inside the net bag, which is conducive to the growth and development of aquatic products. It can be seen that the device for feeding and acclimatizing mandarin fish provided by this utility model embodiment can improve the catching effect.
[0022] To facilitate artificial feed domestication, in some embodiments, the device for feeding and domesticating mandarin fish provided by this invention further includes: a horizontal plate 5 and a horizontal support. The horizontal support is fixedly connected to the column frame 2 and is used to support the horizontal plate 5. The horizontal plate 5 is higher than the horizontal tie member 3. Further, in some embodiments, the top of the column frame 2 is half a meter higher than the horizontal plate 5, and the horizontal plate 5 is suitable to be flush with the water surface. In this way, the feeder can simply sit down to contact the water surface and observe the feeding and activity levels of the mandarin fish, unlike traditional floating cages where the feeder needs to lean out to reach the water, thus reducing labor intensity and improving work efficiency.
[0023] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
