Description

Laser breaking device

Technical field

[0001] The present invention relates to the field of chicken smashing, and more particularly to a laser smashing device.

Background technique

[0002] Modern large-scale chicken production, due to the high density of breeding, chickens are easily injured by each other. At the same time, unbroken chickens will waste feed when they eat. Therefore, in order to reduce mortality, save feed, and cut chickens, it is one of the necessary operations for modern scale farming.

[0003] The current mainstream breaking method is a mechanical breaking method, which is also called a hot cutting jaw breaking method. The mechanical smashing method is generally used when the chicks are 7-10 days old and are broken by a mechanical breaker (also known as a mouth-cutting machine). The mechanical breaker uses a hot blade to reciprocate up and down. The temperature of the blade is about 800 degrees Celsius. There is a chicken mouth fixing hole at a vertical distance of about 1-3 mm from the blade cutting position. The chicken mouth passes through the fixing hole and enters the blade. The cutting range is thus cut by the blade. After cutting, the operator will place the section of the crucible on the blade for 2 to 3 seconds. Repeated burning can stop bleeding, prevent infection, and flatten the section to prevent the chicken from growing new during the growth process. Mechanical breaks should be selected by experienced workers. If the breaks are not easy, the chicks will die, the growth and development are poor, the uniformity is poor, and the egg production rate rises slowly or without peaks, which brings great economic losses to the chickens. .

[0004] Therefore, mechanical breaking equipment has the following problems: 1. Mechanical breakage using a hot blade, the mechanical shearing force of the chicken cockroach is large, the damage to the chicken is large, and the mortality is increased; 2. The high temperature burns the burn mouth, It will cause a greater stress response in the chicken, which increases the difficulty of subsequent feeding and care; 3. The simple aperture is fixed, the flexibility of the chicken mouth entering the cutting plane of the blade is large, the difficulty of the breaking operation is increased, and the breaking is impossible. Standardization and precise control have high technical requirements for the operator; 4. The large damage and the difficulty of operation determine that the mechanical break can only be used for the breakage of large day-old chicks, but not for low-day chicks (such as 1 Rishen Chicken) to operate. With the above-mentioned limitations, most of the operations of mechanical breakage can only be carried out by farmers, and they cannot be concentrated or automated in the hatchery, which reduces the efficiency of the entire farming industry.
