Large-egg-turning-angle hatching machine

Abstract

The invention provides a large-egg-turning-angle hatching machine. The machine includes a hatching tank, a humidity control system, a temperature control system, a water spray system, an air circulation system, an egg turning device, an egg tray and a master controller; the egg turning device comprises an egg rack, a power source and a transmission mechanism, the egg tray is supported on the egg rack, under the control of the master controller, the power source drives the egg rack to do reciprocating oblique motion through the transmission mechanism, the egg tray does reciprocating oblique motion along with the egg rack to achieve egg turning, after the egg tray turns away from the horizontal position along with the tray rack and becomes oblique, the structure of the egg tray makes eggs vertically placed in the egg tray tilts along with the egg tray and is tilted at a certain angle in the egg tray in the same direction, and the eggs are thus turned from a horizontally laid state on one side to a horizontally laid state on the other side. By means of the large-egg-turning-angle hatching machine, without changing egg placement and egg tray placement processes, the egg placement and egg tray placement processes are kept as simple as possible, a large egg turning angle is achieved and is close to 180 degrees, and therefore the hatching machine helps to break through the hatching rates of the eggs.

Description

technical field [0001] The invention relates to the technical field of poultry egg hatching, in particular to a large egg-turning angle hatching machine. Background technique [0002] Artificial hatching of poultry eggs is a relatively mature technology. The hatching rate of water poultry eggs can reach more than 80%, which is difficult to improve and has basically reached the bottleneck. [0003] Artificially hatching poultry eggs requires strict control of the temperature and humidity during the hatching process, as well as ventilation, cooling eggs, turning eggs, etc. The ventilation is used to make the eggs obtain enough oxygen, and the cooling eggs are used to drain away the biological heat during the egg hatching process. , Turning eggs is used to prevent embryo adhesion. [0004] At present, there are no different incubators for poultry eggs such as chicken, duck, and goose eggs, but the egg trays used are different. The egg turning device of the incubator is compos...

AI Technical Summary

Problems solved by technology

[0010] 1) The egg turning angle is generally in the range of 90°, and it is impossible to achieve a large-angle egg turning close to 180°;

[0011] 2) The efficiency of the air circulation system is low. There are two main reasons for this: first, the rotation axis of the fan is perpendicular to the rotation axis of the egg rack. The front or back of the tray is facing the fan, and the wind path is blocked, resulting in poor air circulation; second, the eggs are placed in rows in the egg tray, and the egg trays are placed in layers on the egg rack, resulting in hatching space. There are many spaces with leeward wind and narrow air path, it is difficult for the blower fan to blow the wind into these spaces

[0013] The above egg rack itself can be turned over by a large margin. The factor that really limits the angle of egg turning is that the egg tray is easy to fall off from the egg rack when the turning angle is large, and the eggs are also easy to fall off from the egg tray.
