Description

Technical Field

[0001] The utility model belongs to the technical field of biological breeding and relates to a fly egg hanging device. Background Art

[0002] With the rapid development of domestic aquaculture, the demand for high-protein feed is increasing. Maggots are the larvae of houseflies. Their nutritional content is similar to that of high-quality fish meal, containing about 55%-65% protein and rich in various amino acids. They are a high-quality animal protein feed. At present, the breeding of maggots is divided into two stages: breeding flies and maggot breeding. Breeding flies is to obtain a large number of fly eggs for breeding maggots. The lifespan of male breeding flies is generally only 7 days, and the lifespan of female breeding flies is generally 15 to 25 days. Fly eggs usually refer to housefly eggs, which are male The product of the mating of male and female breeding flies is generally milky white, banana-shaped or oval, and about 1 mm long. After mating, female breeding flies will lay eggs in the hatching tray, and the fly eggs will hatch into larvae (i.e. maggots) after a period of time. The breeding of maggots has high requirements for temperature. Below 20°C, the breeding flies will stop reproducing or enter hibernation, not eating or moving. The fly eggs will be directly frozen to death in an environment that is continuously below minus 5°C and cannot develop into maggots. If the maggots continue to be in an environment below 0°C, they will soon die.

[0003] At present, fly maggots are usually farmed in simple plastic greenhouses, where the temperature and humidity cannot be precisely controlled. The hatching trays are densely placed on the ground inside the greenhouse, and the space inside the greenhouse cannot be effectively utilized. Therefore, the existing fly maggot farming method is relatively extensive, and the farming technology is not advanced enough, resulting in low efficiency and yield of fly maggot farming, and large losses of breeding flies. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and propose a fly egg hanging device. The technical problem to be solved by the present invention is how to improve the efficiency and yield of fly maggot breeding and reduce the loss of fly species during the breeding process.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A fly egg hanger is characterized in that it includes a hanger and a hatching tray, the hanger includes a main rod and a plurality of supporting rods arranged on the main rod, the upper end of the main rod is provided with a hanging part, the supporting rods are arranged at intervals along the length direction of the main rod, and the plurality of supporting rods located at the same length position of the main rod are arranged vertically and horizontally to form a bracket, and the hatching tray is arranged on the bracket.

[0007] The brackets of the fly egg hanger are arranged at intervals along the length direction of the main rod, so that the hatching tray can be placed along the longitudinal direction of the breeding space. At the same time, the bracket is formed by a plurality of brackets located at the same length position of the main rod and arranged in a vertical and horizontal manner, so that the hatching tray can be placed horizontally along the same bracket, thereby realizing the three-dimensional placement of the hatching tray, thereby improving the utilization rate of the breeding space, providing more hatching sites, allowing the breeding flies to reproduce as much as possible within a limited life span, thereby improving the efficiency and yield of fly maggot breeding, and reducing the loss of fly maggots during the breeding process. In addition, the hanging parts of the fly egg hanger can be hung on the hanging rail, so that the fly egg hanger can also be used for the automated breeding of fly maggots.

[0008] In the above-mentioned fly egg hanger, a connecting plate is fixedly connected to the bracket, and the connecting plate is connected to the main rod. The connecting plate can enhance the structural strength of the bracket and also facilitate the connection between the bracket and the main rod.

[0009] In the above-mentioned fly egg hanger, the two connecting plates are symmetrically and detachably arranged on the side walls of the main rod. This structure not only makes the connection between the bracket and the main rod more stable, but also facilitates the disassembly and assembly of the bracket and the main rod, making the inspection and replacement of the fly egg hanger very convenient.

[0010] In the above-mentioned fly egg hanger, the supporting rod is provided with a plurality of upwardly protruding limiting portions, and the limiting portions are located at least at both ends of the supporting rod.

[0011] In the aforementioned fly egg hanger, the hanging member is in the form of a rectangular frame, the lower end of which is hinged to the main rod. This rectangular frame shape facilitates the installation of the hanger and facilitates lifting by a robot or a human. Hinging the lower end of the hanging member to the main rod allows the fly egg hanger to better achieve steering when it is moved along the hanging rail to a corner during automated breeding.

[0012] In the aforementioned fly egg hanger, a hanging plate is provided on top of the hanger member, and a hanging hole is formed on the top of the hanging plate. The hanging hole is located on an extension of the central axis of the main rod. This structure ensures that after the hanger is hung, the hanging point and the central axis of the hanger are aligned on the same longitudinal line. This prevents the hanger from shaking due to the deviation between the center of gravity and the hanging point, and the hanger is more stable.

[0013] In the aforementioned fly egg hanger, the top of the hanger and the bottom of the hanger plate both have V-shaped cross-sections, and the top of the hanger is mounted on the bottom of the hanger plate. Once mounted, the top of the hanger is embedded in the bottom of the hanger plate, limiting the hanger and the hanger plate in the front-to-back direction. Simultaneously, the rectangular frame-shaped hanger limits the hanger plate in the left-to-right direction, allowing the hanger to be stably suspended on the hanger plate. To remove the hanger, the hanger can be lifted upwards by a robot or manually, and the hanger can be detached from the hanger plate. This results in a simple structure and ease of use.

[0014] In the aforementioned fly egg hanger, a guide limit hook is provided at the bottom of the main rod, with the opening of the guide limit hook facing the side wall of the main rod. In automated breeding, the guide limit hook can be hung on the ground rail, allowing the rope egg hanger to be more easily moved within the breeding room along the upper and lower oppositely arranged hanging rails and ground rails.

[0015] Compared with the existing technology, the advantages of the fly egg hanger are: the brackets of the fly egg hanger are arranged at intervals along the length direction of the main rod, so that the hatching tray can be placed along the longitudinal direction of the breeding space; at the same time, the bracket is formed by a plurality of brackets located at the same length position of the main rod and arranged in a vertical and horizontal manner, so that the hatching tray can be placed horizontally along the same bracket, thereby realizing the three-dimensional placement of the hatching tray, thereby improving the utilization rate of the breeding space, providing more hatching sites, allowing the breeding flies to reproduce as much as possible within a limited life span, thereby improving the efficiency and yield of maggot breeding, and reducing the loss of breeding flies during the breeding process; in addition, the hanging plate of the fly egg hanger can be hung on a hanging rail, so that the fly egg hanger can also be used for automated breeding of maggots.
