Description

Technical Field

[0001] The invention relates to the field of automatic egg tray transmission in a new mode of direct hatching of poultry embryo eggs, and in particular to an egg tray transmission device for hatching embryo eggs in a breeding house. Background Art

[0002] The hatching and rearing of broiler poultry have historically been conducted in two relatively independent locations. This current model presents several shortcomings: Chicks from the hatchery must be transported long distances to the breeding farm, where they lack access to water, food, and an unsuitable environment. This transport deteriorates the birds' health, leading to wear and tear and stress. Upon arrival at the breeding farm, the chicks must be re-caged and placed in cages, reusing the existing environmental conditions within the breeding house. This significantly slows their growth and prevents them from achieving optimal growth targets for large-scale broiler production, resulting in significant economic losses for the farm. Furthermore, after being transferred to the breeding facilities, chicks are typically placed only in the middle brooding layer. After a certain age, they are separated into upper and lower pens, a process that also causes stress for the birds. Prior to separation, the cages on the other tiers, except for the birds on the brooding tier, remain idle, preventing optimal utilization of the breeding facilities. Summary of the Invention

[0003] The present invention aims to overcome the deficiencies in the prior art and provides an egg tray conveying device for hatching embryonated eggs in a breeding house.

[0005] On the basis of the above technical solutions, the following further technical solutions can be provided: The set of suspensions is also provided with a chain guide groove matched with the chain pair.

[0006] A tensioning assembly corresponding to the chain is provided on one side of the driving motor.

[0007] The suspension comprises a crossbar parallel to the crossbeam, and connecting rods connected to the crossbeam are arranged at both ends of the crossbar.

[0008] The tensioning assembly is provided with a base plate on the mounting frame of the driving motor, a vertical movable seat is provided on the base plate, long holes distributed corresponding to the vertical movable seat are provided on the base plate, a rotating shaft with one end passing through the long hole is provided on the vertical movable seat, a tensioning gear corresponding to the chain is provided on the rotating shaft, and chain guide wheels corresponding to the chain are provided on the base plate on both sides of the long hole.

[0009] Advantages of the invention: The invention has the advantages of simple structure, easy use, and can stably transport egg trays for hatching embryo eggs in a breeding house, thereby effectively improving the survival rate of chicks, reducing breeding costs, and improving benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the present invention; Figure 2 It is a schematic diagram of the three-dimensional structure of the present invention.

[0011] Specific implementation method: like Figure 1 and 2 As shown, an egg tray transfer device for incubating embryonated eggs in a breeding house is shown. A set of crossbeams 7 are mounted on the top of the cage, with a suspension 5 connected to each crossbeam 7. The suspension 5 includes crossbars 5a extending parallel to the crossbeams 7, with connecting rods 5b at each end connecting to the crossbeams 7. The cage is a common device in the breeding industry, consisting of a metal frame and cage mesh, and will not be described in detail here.

[0012] A pair of egg tray holders 3 are mounted on crossbars 5a of a set of hangers 5. Chain guides 2 are installed on both the upper and lower surfaces of the crossbar 5a between the two egg tray holders 3. The egg tray holders 3 on the outermost hangers 5 extend a distance beyond the cage. A reinforcing plate 5c is installed below the crossbar 5a to mate with the chain guides 2 below.

[0013] A drive motor 6 and a driven sprocket 6a are mounted on the cage's outer ends via mounting brackets. A chain 1 is attached to the driving sprocket 6b and the driven sprocket 6a on the drive motor's output shaft. The chain 1, located within the cage, moves within a chain guide 2. A set of spaced-apart egg tray stoppers 1a are attached to the chain 1. One end of each egg tray stopper 1a extends a distance beyond the chain guide 2, forming a rear hook-like structure at its end.

[0014] A tensioning assembly 4 is provided on one side of the drive motor 6, corresponding to the chain 1. The tensioning assembly 4 comprises a base plate 4a mounted on the mounting bracket of the drive motor 6, and a vertically movable base (not shown) mounted on one side of the base plate 4a. The vertically movable base includes a vertical lifting device, which is a conventional pneumatic, hydraulic, or electric cylinder, with a rotating shaft mounting base connected to its output end.

[0015] Long holes 4c distributed corresponding to the vertical movable seat are provided on the bottom plate 4a, a rotating shaft with one end passing through the long hole 4c is installed on the vertical movable seat, a tensioning gear 4b corresponding to the chain 1 is provided on the rotating shaft, and chain guide wheels 4d corresponding to the chain 1 are provided on the bottom plate 4a on both sides of the long hole 4c.

[0016] For easy viewing, Figure 2 Chain 1 in is not fully displayed.

[0017] Working process: On one side of the driven sprocket, a worker places a filled egg tray 8 between adjacent egg tray stoppers 1a, with the bottom support of the egg tray 8 in contact with the egg tray holder 3. Eggs to be hatched are then placed on the egg tray holder 3. The drive motor 6 is then started to pull the filled egg tray 8 into the cage. The egg trays 8 and eggs are placed sequentially. The drive motor continues to pull the filled egg tray 8 into the cage until the entire row of cages is filled with egg trays. The drive motor is then shut down. The incubator in the cage is turned on for incubation.

[0018] When the incubation is completed, the drive motor is started to reverse, and the empty egg trays are withdrawn one by one. The staff can remove the egg trays one by one.
