Description

Technical Field

[0001] The utility model belongs to the technical field of food marinating equipment, in particular to a poultry egg shelling device. Background Art

[0002] In modern farming, poultry such as chickens and ducks are mainly raised, and the eggs produced by chickens and ducks are one of the main economic sources in the farming process. In order to meet the living needs of modern people, eggs are usually shelled after high-temperature boiling and then marinated into finished products for packaging. Before boiling and shelling, the big end of the egg (the air chamber side) needs to be pierced to reduce the egg breakage rate when the egg is boiled at high temperature. However, the piercing of the egg shells still requires manual operation, which results in high labor intensity for the operator and low production efficiency of the egg processing.

[0003] Therefore, in the technical field of poultry egg processing equipment, there is still a need for research and improvement of poultry egg shelling devices. This is also a research hotspot and focus in the current technical field of poultry egg processing equipment, and it is also the starting point for the completion of the present utility model. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to provide a poultry egg shelling device to solve the technical problems of high labor intensity and low production efficiency of the existing poultry egg shelling.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a poultry egg shelling device, comprising a frame, a conveying chain driven by a first power mechanism is installed on the frame, a plurality of conveying rollers are rotatably installed on the conveying chain, each of the conveying rollers is provided with a waist drum-shaped adjustment roller, and the adjustment rollers are arranged in a row; a swinging connector driven by a second power mechanism is installed on the frame, a shelling hammer is provided at the end of the swinging connector, and the shelling hammer corresponds to the position of the adjustment roller.

[0006] As an improvement, the swing connector is an elastic telescopic body.

[0007] As a further improvement, the swing connection body is a spring.

[0008] As another improvement, an egg pressing shrapnel is provided on the frame, and the egg pressing shrapnel corresponds to the position of the shell piercing hammer.

[0009] As a further improvement, in the conveying direction of the conveying chain, the upstream position of the egg-pressing shrapnel is higher than the end position of the egg-pressing shrapnel.

[0010] As another improvement, each of the conveying rollers is mounted with a gear, and correspondingly, a rack matched with the gear is fixedly mounted on the frame.

[0011] After adopting the above technical solution, the beneficial effects of the utility model are:

[0012] (1) The egg shelling device provided by the utility model is provided with a self-rotating adjustment roller. When the egg is transported downstream on the waist-drum-shaped adjustment roller according to its own shape, the large head of the egg is located in the middle recessed position of the waist drum, and the position is basically fixed. When it is detected that the egg reaches the shelling hammer position, the shelling hammer swings to shell the egg, thereby realizing automatic operation and replacing traditional manual shelling, reducing the labor intensity of the operator and improving production efficiency.

[0013] (2) Since the swing connector is an elastic telescopic body and can have a certain amount of expansion and contraction, under the action of the swing cylinder, the shelling hammer swings back and forth, generating a centrifugal force, which can extend the swing connector to a certain length. For poultry eggs with smaller volume specifications, the shells can also be pierced. For poultry eggs with larger volume specifications, when the shelling hammer hits the poultry eggs, the swing connector can produce a certain amount of deformation, so that the shelling force is not too large to damage the poultry eggs. The elastic swing connector automatically compensates for the deformation through the amount of deformation, meets the requirements of a wider range of poultry egg specifications, and improves the performance of the utility model.

[0014] (3) Since the frame is provided with an egg pressing shrapnel, the poultry eggs are fixed on the adjustment roller under the action of the egg pressing shrapnel, so that the poultry eggs are prevented from jumping when the shelling hammer is used to pierce the shells, thereby improving the shelling effect.
