Description

Technical Field

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

[0002] With the rapid development of the domestic aquaculture industry, the demand for high-protein feed is increasing. Maggots are the larvae of houseflies (maggots are hatched from fly eggs after a period of time, and fly eggs are the product of mating between male and female breeding flies). Their nutritional composition 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.

[0003] At present, fly maggots are usually farmed in simple plastic greenhouses, with hatching trays densely placed on the ground inside the greenhouse. Female breeding flies lay eggs in the hatching trays after mating. However, the lifespan of male breeding flies is generally only 7 days, while the lifespan of female breeding flies is generally 15 to 25 days. In addition, the space on the greenhouse floor for placing hatching trays is limited. In other words, 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-laying thread. The technical problem to be solved by the present invention is how to improve the efficiency and yield of fly egg-laying and reduce the loss of fly eggs during the breeding process.

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

[0006] A fly breeding egg-laying line is characterized in that it includes a plurality of columns arranged on one side of the wall of a fly breeding room, the plurality of columns are arranged at intervals along the length direction of the wall, the columns are provided with support rods extending away from the wall, a track is provided between the plurality of support rods, the track is provided with a plurality of pulleys, and the pulleys are connected to a hanging plate for hanging.

[0007] The fly egg-laying line is provided with a plurality of columns on one side of the wall of the fly breeding room and support rods extending from the columns in a direction away from the wall, so that a track can be firmly set between the support rods, which matches the characteristic of flies being suitable for walking on vertical walls. A hanging board for hanging is slidably provided on the track, and the hanging board can be used to hang a hanger for placing a hatching tray. A plurality of hanging boards can be provided, and the hanging boards are connected to pulleys so that the hanging boards can move along the track, thereby providing sufficient hatching space, thereby improving the efficiency and yield of fly egg laying, and reducing the loss of fly eggs during the breeding process.

[0008] In the aforementioned fly breeding line, the track has a track groove extending along its length, the notch of the track groove being located at the bottom of the track, and the pulley is disposed within the track groove. By concealing the pulley within the track, the pulley is prevented from crushing the fly breeding line during sliding, thereby reducing unnatural loss of fly breeding lines during the breeding process.

[0009] In the above-mentioned fly egg-laying line, a hanging hole is formed on the top of the hanging plate, a connecting pin is passed through the hanging hole, and connecting plates are respectively provided at both ends of the connecting pin. The upper ends of the two connecting plates are abutted against each other and extend into the track groove to be connected to the pulley axle, and the connection between the connecting plates and the pulley axle is located directly above the hanging hole. By providing the connecting pin and the connecting plates at both ends of the connecting pin, the hanging plate is more stably connected to the pulley. At the same time, the connection between the connecting plate and the pulley axle is located directly above the hanging hole, so that the hanging point of the hanging plate and the hanging hole of the hanging plate are on the same longitudinal straight line. In this way, after the hanging plate is hung, it will not shake due to the deviation between the center of gravity and the hanging point position, and the suspension is more stable, thereby improving the efficiency and yield of fly egg laying.

[0010] In the aforementioned fly egg-laying line, the tip of the bottom of the hanging plate is located directly below the hanging hole. Furthermore, when the fly egg hanger is hung on the hanging plate, the hanging point of the fly egg hanger and the hanging point of the hanging plate are aligned in the same longitudinal line. This prevents the fly egg hanger from shaking due to a misalignment between its center of gravity and the hanging point, resulting in a more stable suspension and improved egg-laying efficiency and yield for the fly.

[0011] In the aforementioned fly egg-laying line, the bottom of the hanging plate has a hook-shaped portion, and the hook-shaped portion is V-shaped. The V-shaped hook portion, i.e., the hook portion has a plate-like structure that is wide at the top and narrow at the bottom, facilitates the insertion and removal of the hanger. Furthermore, after the hanger is hung, the hanger's hanging member can be embedded in the hook portion and form a horizontal mutual restraining structure with the hook portion, thereby improving the hanging stability of the hanger, thereby reducing the shaking of the hatching tray on the hanger, and improving the efficiency and yield of fly egg laying.

[0012] In the above-mentioned fly egg-catching line, a reinforcing rod is provided between the upright post and the support rod thereon, and the reinforcing rod, the upright post, and the support rod are arranged in a triangular pattern. By providing the reinforcing rod and the triangular pattern between the reinforcing rod, the upright post, and the support rod, the structural strength of the upright post and the support rod can be improved, thereby better supporting the track thereon.

[0013] Compared with the existing technology, the advantages of this fly egg-laying line are: this fly egg-laying line is provided with several columns on one side of the wall of the fly breeding room and support rods extending from the columns away from the wall, so that a track can be firmly set between the several support rods, and several hanging boards for hanging are slidably provided on the track. The hanging boards can be used to hang hangers for placing hatching trays, thereby providing sufficient hatching space, thereby improving the efficiency and yield of fly egg-laying, and reducing the loss of fly eggs during the breeding process.
