GROUNDING THE OPERATING PARAMETERS OF THE DEVICE FOR AUTOMATIC REMOVAL OF THE MILKING MACHINE SUSPENSION PART FROM THE COW'S UDDER
Overexposure milking machines on the animal's udder causing a negative impact on the mammary gland, which leads to disease and culling cows. In this regard, the milking machine must not only ensure the complete milking, but the timely removal of the teat cups to the udder. In order to solve this problem, the authors developed a device for the automatic removal of the suspension of the milking machine at the end of milking. This device includes a pneumatic motor, a reducer and a drum with a flexible thread. In a theoretical consideration of the working process of the removal of the suspension obtained analytical dependence, which allows you to determine the desired angular velocity, and accordingly, the device drum rotational speed for the automatic removal of the suspension of the milking machine at any time, except it hit the floor stall. Also invited to the equation by which you can determine the duration of the process of removing suspended at the end of milking. The use of the design formulas shown that the optimum drum rotation frequency is 98-104 min-1, respectively, the suspension filament speed is equal to 0.22-0.24 m / s, and the duration of the withdrawal process - 7-8 c.
