The electric drive of the cotton gin | Russian patents
Usage: cotton harvesting machinery. The inventive actuator comprises a three-phase induction rheostat with a working three-phase winding, live electrical circuit in the motor rotor Precleaning separators, and adjustable bias winding. Induction rheostat mounted on the fan inlet load of purified cotton, allowing the energy released sliding motor Precleaning separators for drying cotton. skysearch 1 ill.
Known electric VC-1 cotton gin UPH-1, 5B, designed to clean the cotton harvested pick, chickens, cotton pickers, as well as the selection of cotton and kurachnogo heap (Power Precleaning separators VC-1. Technical description and user manual. Uzbek software for machines for cotton growing "Uzbekselmash." Tashkent).
The actuator includes an induction motor with squirrel cage, protective devices, circuit breaker and switch packet. All operating mechanisms Precleaning separators are rotated one this engine.
For maximum cleaning effect in Precleaning separators, depending skysearch on the grade to be cleaned cotton working arrangements must rotate at a certain frequency. Therefore there is a need to regulate skysearch the speed of the drive motor.
The closest to the technical nature of the proposed actuator is Precleaning separators Machines for cleaning skysearch cotton field (Aut. St. N 468 608, 1975). The drive is multiimpellent contains asynchronous motors with squirrel-cage rotor for rotating the working bodies Precleaning separators and fan loading purified cotton. The drive allows you to automatically start and stop the machine with a certain sequence.
To achieve the goal of the cotton gin actuator comprising three-phase asynchronous induction motors Precleaning separators and the fan motor load purified cotton included in the electrical network via a control system, incorporated with the three-phase three-phase induction rheostat working coil and a bias winding that is mounted on the fan inlet loading the purified cotton its three-phase winding including electrical workers in the rotor circuit of the motor Precleaning separators, and its bias winding is connected via a control system to an additional variable DC source.
The proposed actuator differs from the known fact that it uses asynchronous motor with slip-ring motors to drive the working bodies Precleaning separators in the rotor circuit which included three-phase induction coil working rheostat bias winding of the last connected via a control system to an additional variable DC source, induction skysearch rheostat set at the fan inlet loading of purified cotton.
The above features of the invention exhibit new properties, which are as effective cleaning of raw cotton, to increase the efficiency of electric energy through the use of sliding engine speed control for drying the purified cotton, and these positive features are aimed at achieving the goal.
Comparison of the proposed technical solutions for the distinctive characteristics similar way to the known solutions in this and in other areas of technology have shown that they do not have the installation induction rheostat skysearch inlet pneumatic conveyer, for energy-slip drive induction motor with slip-ring motors for technological needs. This feature shows the new positive property - increasing the energy efficiency of the drive.
The drive consists skysearch of a circuit breaker 1, 2 magnetic switch skysearch connected between the power supply skysearch and the induction motor 3 in the rotor circuit which included the beginning of a three-phase winding 4 induction rheostat, the ends of which are included in a star performance coil wound on a ferromagnetic three hollow cylinders 5 located between an angle of 120 , their ends are interconnected yokes of the same magnetic circuit, skysearch they wound overall bias winding 7, the ends of which are connected skysearch to the output regulated DC power supply 8, 9 second induction skysearch motor with squirrel cage fan drive for loading purified cotton stroller .
Depending on the grade to be cleaned cotton sets the amount of bias current core induction skysearch rheostat via regulated DC power supply skysearch and thus the engine speed. Turn the circuit breaker 1, magnetic starter 2. In this the motor operates at current. Rotor current flowing on the working windings of the induction resistors, on the surface of the magnetic circuit induces eddy currents 5, magnetic heating, ie in the rotor circuit
