Technical revolution in control and automation of tractors and mobile machines (state and perspectives)

Novikov G.V.


Last years a microprocessor technical revolution in automatics and control of mobile machines has occurred. Their elements have changed dramatically and their possibilities have essentially, cardinally extended. In the paper the condition of serious backwardness in this area of technics from a technological level of the advanced countries is ascertained, opportunities and prospects of development of automatics and controls in our country in new conditions are estimated. Personnel opportunities of development are estimated sceptically.

Modernized crusher for fodder grain

Shirobokov V.I., Ivanov A.G., Fedorov O.S.


In agricultural industry the hammer grinders are the main devices for grinding grains. The lock of sifts in the operational area of the grainder prevent the removal of the ready product is the main drawback of these grainders. It can lead intensive formation of dust, wear of sift and hammer and over usage of electricity. More raised construction of the grinder allows to overcome all the drawbacks. The separator allows to define the main parameters of cylinder part of separating sift.
