Description

Semi-automatic fluff cleaning equipment for brooding chicken house

Technical Field

The invention belongs to the field of animal husbandry machinery, and in particular relates to a semi-automatic fluff cleaning device for a brooding chicken house, which can be used to efficiently clean fluff, feed particles, dust and other debris on the floor of a walkway, the bottom of a cage and the dead corners of the edge.

Background technique

In the egg-laying chicken breeding process, brooding chickens molt for the first time between 6 to 8 days and 4 weeks of age, and the down is replaced by the first new feathers. The shed down will randomly fall on the walkways of the brooding house, the ground under the cages, and accumulate, and it is very easy to become a carrier source of air pollutants such as dust, odor, and microorganisms, seriously affecting the health and biosafety of the indoor environment. In addition, modern chicken farms are large in scale, and the amount of chicks molting is large and concentrated in time. The problem of down cleaning has always been a problem that plagues brooding production. Taking a brooding house that raises 8,000 chickens in a single batch as an example, the down is cleaned twice a day, and about 2 kg of down can be collected each time. In the daily management of the brooding house, it is necessary to ensure the cleanliness of the chicken house. There should be no dust, food, or feathers on the ground, otherwise it will be detrimental to the healthy growth of the chickens and will also endanger the health of the staff.

Due to the lack of special equipment, existing brooding chicken houses are often cleaned by hand-pushed unpowered sweepers, household negative pressure vacuum cleaners, industrial vacuum cleaners and other equipment, which have limited cleaning effects and many disadvantages, and cannot meet the actual requirements of fluff cleaning. Because the fluff is small in size and light in weight, with a density of about 0.005g/ ^cm3 , a large amount of dust and fluff resuspension will be generated during the forward movement of the hand-pushed sweeper, and it is easy for fluff, dust, etc. to be scattered to the bottom of the chicken cage bracket and other cleaning dead corners. To solve this problem, watering is often carried out in production to assist cleaning, but it is easy to cause new problems of fluff sticking to the ground, increasing the difficulty of cleaning; in addition, watering will change the humidity in the house, which may have a potential impact on normal production. Household negative pressure vacuum cleaners are designed for home spaces, and the dust box space is small. It takes multiple dumps to completely clean the chicken house once, and the fluff is easy to clog the filter, reducing the ventilation volume, and the efficiency of later operations is low. Industrial vacuum cleaners are extremely inconvenient to operate in the chicken house space due to their large size, strong suction power, and the need to drag the power supply back and forth. They also have the key problem of filter clogging and are not suitable for cleaning chicken house fluff.

In order to reduce the waiting time when the equipment is working and the amount of sewage generated by spraying, the spraying time each time should not be too long. The wind speed is higher in the middle area of the pipe and lower at the edge, so the fluff is mainly blocked in the middle area of the filter. Considering the spraying time and spraying effect, each spray can clean 4/5 of the area near the center of the filter.

Furthermore, there may be multiple nozzles 166, and it is only necessary to ensure that the spraying area covers the first layer of filter screen 131. However, under the premise of ensuring the spraying effect, the water spraying volume should be as small as possible.
