Manual milking of cows – it’s not an easy task, it takes a lot of time and requires effort. This is especially difficult when there are many animals in the herd, and everyone needs to be given attention. To help the milkmaid, automatic milking machines have been developed. Let's look at the production characteristics of the Doyushka milking machine, its pros and cons, how it works and use according to the instructions.
Device manufacturer
A milking machine called “Doyushka” was developed and manufactured in the city of Miass, which is located in the Chelyabinsk region. The company produces milking units for milking cows, mares, goats, and sheep.Spare parts for the units are also produced, which can be purchased separately.
The most popular models are “Doyushka 1R” and “Doyushka 1C”. They also produce machines for joint milking of a pair of cows - “Doyushka Tandem” and a version with a larger volume can - “Doyushka Universal”.
How does the device work?
The Doyushka apparatus uses a piston pump; due to its special design, it operates more silently than a vacuum pump. The pump mechanism produces 64 strokes per minute - the same as a calf does when suckling milk. Because of this, the cow remains calm. The seal is created by a replaceable leather cuff, and a pressure gauge controls the operating pressure.
Four glasses, which fit over all teats, have inserts made of transparent material, so you can control the flow of milk from each lobe of the udder. Smartly designed glasses fit over cow nipples quickly and easily, do not cause discomfort in animals.
The milk is poured into a large stainless steel can. It closes with a lid, it has a handle, you can attach equipment to it when milking. The can stands on a platform with sides, which makes it stable. The entire apparatus can be moved; wheels are built into the lower part of the frame (one of them is steering and 2 are load-bearing).
The engine of the Doyushka device is durable, the motor is controlled by a button, which can be used to turn the device on or off.
The operating principle of the milking machine "Doyushka"
When you turn on the device, the pump starts working, the piston in it moves up and down. Due to the movement of the piston and the valve placed on the pump cover, a vacuum is created. When rarefied, milk is sucked from the nipples into glasses, from which it flows into the can. When the container is completely filled, the device can be turned off.
In order for the Doyushka cow machine to work properly and for a long time, you need to take care of it: rinse the equipment of milk liquid and lubricate the piston and cylinder every week. You can clean it with special brushes that are included with the unit.
Advantages and disadvantages
Despite the minor shortcomings, the unit is in demand among consumers due to its reliability and quality.
Specifications
The weight of the unit is 52 kg, height – 78 cm, length – 1 m, width – 39 cm. The device is equipped with a can with a volume of 22.6 liters. “Doyushka” consumes 550 watts, voltage – 220 V. Vacuum pressure – 40-50 kPa, pulsation frequency – 64-74 times per minute. Using a milking machine you can get milk from 5-8 cows per hour.
Instructions for use
For safety reasons, the electrical wiring to which the unit is connected must be equipped with a residual current device. Before turning on the Doyushka, you need to make sure that the voltage in the network corresponds to what is necessary for the normal operation of the device.
Before use, you need to assemble the device. Turn it on, then it should sit for 3-5 minutes. run idle. If there is no extraneous noise from moving mechanical parts, you need to wash the milking equipment.
Before starting milking, you need to check the pressure that is formed in the installation. If the vacuum level is higher or lower than recommended, you need to adjust it with the control valve located on the milk receiver to the recommended values - 0.04-0.045 MPa.
Before you start milking, you need to wash the cow's udder, then lightly massage the udder. Place the milking cups on the teats: take the milk receiver with one hand (the pipes and the splitter should be directed upward, and the cups should be directed downward). With the other hand, place the glasses one at a time on the nipples.
After this, holding the milk receiver, you need to unscrew the pressure regulator to remove the vacuum. Only after this can you remove the glasses by removing them one by one from the nipples. The final stage is treating the nipples with disinfectants. After this, you need to hang the equipment on the installation handle, then lift the lid covering the can, pour the resulting milk into a separate container and proceed to milking the next animal.
When all the cows have been milked, you need to rinse the equipment first with clean water, then put it in a container with hot water or with the addition of a disinfectant and turn on the installation. Repeat rinsing as many times as possible until the water is clear. Rinse the hoses and the inner surface of the can.
Every week you need to remove the milk receiver, can, glasses and clean them of milk residues with a brush. After the same period of time, you need to disassemble the pump, lift the leather gasket and lubricate the parts with oil (to improve sealing and reduce friction).
Replace nipple liners once every 4 weeks, especially if cracks or damage appear on them. Also monitor the condition of the hose rubber. Store the Doyushka milking machine in a dry place. The Doyushka unit is intended for home use. It facilitates the milking process and is comfortable for animals and humans. It greatly facilitates the work; it is especially important to use it if the farm contains several animals. "Doyushka" allows you to reduce the time spent on milking and makes difficult work easier. If you handle the unit with care, it can last a long time.
