Milk production on farms is greatly simplified if the AID 2 milking machine is used. And the AID 1 aggregate is used for distributing heifers. These mobile devices are suitable for large and medium-sized livestock (no more than 50 heads). The equipment facilitates the work of employees and reduces the time of milking. Without the mechanization of the process on farms with an impressive amount of cattle, obtaining a dairy product would be an impossible task.
The principle of operation of milking devices
In any milking installation there is a vacuum pump. In some products that can be made to order, there is also a node for creating overpressure.
But in standard milking machines the principle of operation is created on the basis of a vacuum. It is he who helps milk to move from the nipples to the glasses worn on them. The product is then transferred to any suitable container, like a can or bucket. After that, special milk lines pump the liquid into the main tanks.
The milking device is of different types - push-pull or three-stroke. The work of the first is relatively simple. These are just functions for compressing the nipple and pumping out milk from it.
Three-stroke devices are somewhat complicated, since they are adapted to the physiological characteristics of the organism. This means that during operation, each nipple is alternately compressed, the milk is sucked away, and a pause is waited, during which the udder returns to its original state. It is necessary to restore the blood supply.
For other devices with three-stroke mode, see the article "Milking machines" My Milka. "
Designed for distribution
The model of the milking machine AID 1 is designed to facilitate milking of cows and for distributing animals on dairy farms. It belongs to the work of the two-stroke type and sucks the milk out of the nipple using a vacuum.
The unit includes a suspended part of the milking machine, a pulsator, a bucket with a lid, a gasket, hoses and various fittings. To make the milking process more qualitative, the air suction system is thought out.
It is also known equipment called AID 1-01. The system is mobile, as it is placed on a two-wheeled cart. The principle of action - the suction of milk with the help of teat cups under the action of vacuum. AID 1-01 includes a vacuum gauge, a regulator, a hermetically closing bucket, and a silencer. Motor power 0.6 kW. Before starting the milking, the farmer needs to set the correct amount of vacuum. If the device is push-pull, then it is 380-400 mm Hg, if three-stroke, then 450-480.
When a cow is transferred to machine milking, it must be capable of full milk recovery, while taking into account the shape of the udder and teats.
Malfunctions in the operation of the unit, such as insufficient vacuum, incorrect pulse rate and varying degrees of wear of parts, lead to inefficient milking. To avoid this, twice a year, a health check of the entire system is carried out.
It works reliable vacuum
The AID 2 device is similar in appearance to the first device presented. It is also mobile and quite mobile. The clear advantage is that the elements are securely fastened to the nipples, and the quality of the vacuum unit is ensured.
- a pump with graphite plates acts dry and therefore does not require lubricants;
- engine power 750 W;
- rotation of the milking elements occurs at a speed of 1500 revolutions per minute;
- the presence of a thermal relay that does not allow motor overload and is suitable for places with electrical instability;
- during operation, pressure is generated up to 50,000 Pa;
- the device is capable of doing one bench press per second.
With this machine you can milk several cows at a time. At the same time, the udder and nipples are absolutely not injured. The milking machine AID 2-01 was also produced, which is similar in configuration, but consumes less power and has a greater capacity of a vacuum pump.
Among the types of AID 2, we also note mobile individual devices "Udarnitsa", "Victoria", "Duet". They are distinguished by the possibilities of serving a different number of livestock heads and materials for the manufacture of milking containers. For example, the latter type is recommended for a herd of not more than 20 heads. Aluminum buckets used to collect the product can hold 19 or 25 liters of milk, the volume depends on the scope of delivery.
The tank for milk should always be thoroughly rinsed, otherwise the product may deteriorate or an unpleasant smell will appear.
Before starting the AID 2, all parts must be well connected to create a vacuum. You can not use the device for a larger number of heads than the instructions, and also should not use it in small rooms. This is because, during the operation, the technician consumes air and there may be breathing problems.
Plugs are removed from the pipes and the housing is filled with oil. Before switching on, close the cover well and turn the switch to the ready position. After these manipulations, the device is plugged in and the engine starts. Next, you need to fix the elements of the milking machine for AID 2 cows on cattle nipples.
Replacement parts kits
First of all, to extend the life of the AID 2, you need to store it in a collapsible state. In order to detect the damage of various elements in time, it is necessary to inspect them regularly. In the process of applying the unit, most often detected failures of hoses, valves, couplings, fasteners and parts that are attached to the nipples. To work did not stop, you need to have a spare set for replacement.
It is advisable to purchase spare parts directly of the same equipment model. In this case, you can be sure of the authenticity of the parts, and also that it will ideally fall into place.
For safe and high-quality work, in order to eliminate malfunctions, you need to use the AID 2 device in a dry room. Store parts preferably in a dark place and in such a way that fragile parts are protected.
Pros and cons of the device
The most important advantage of machine milking is that the udder relaxes thanks to the massage movements. Good milk yield and high milking speed is ensured. When using AID 2 significantly reduces the risk of inflammatory diseases of the udder (mastitis).
If we consider the advantages in the technical condition of the device, it is the presence of a powerful vacuum pump, the ability to work under different temperature conditions, as well as a fairly simple assembly and installation of the structure.
In addition, the device itself is not heavy - 60 kg. He has a protective casing that protects the farm employee and the cow itself. If there is an overload of the engine, the device is automatically disconnected from electricity.
There are some disadvantages, such as high air consumption, as mentioned above. This may lead to malfunctions. Blowing through the milk-passing channels may not be too strong, which means you need to avoid clogging.
