The utility model is connected with the front output shaft of driving engine, the belt pulley of transmission shaft front side is connected with original driving pulley on the front output shaft by belt, thereby the power of driving engine front output shaft is delivered to the vehicle frame rear portion from the vehicle frame front portion, be convenient to after drag the various agricultural machinery in the railway carriage or compartment to be connected, so that power to be provided.Because driving engine needs only in running order, the front output shaft of driving engine just is in slew mode all the time, and no matter it is to be under which kind of gear, promptly no matter trac. be move ahead, static or retreat, agricultural machinery uses this device all can obtain power, magnetic clutch is installed in the utility model, be used for the cut-out and the connection of power, magnetic clutch is for what often open, and the operation control button can make the friction pair of power-transfer clutch engage, connect power, simple to operate, easy to use.Because front-end bearing pedestal is installed on the dynamo cradle seat of driving engine, and driving engine is that resilient suspension is connected with vehicle frame, trac. bearing seat when operation can produce bob, thereby install universal-joint additional at the two ends of transmission shaft, allowing the angle between the connected part to change within the specific limits, thereby make stable drive.Mlultiple-groove sheave is installed in the transmission shaft rear end, mlultiple-groove sheave can be connected with a plurality of farm implements simultaneously, the tipping bucket that the Hydraulic Pump of installing in a side of rear bearing block can be realized trac. is from unloading functions, and this Hydraulic Pump is also driven by the mlultiple-groove sheave of transmission shaft rear side.
The beneficial effects of the utility model are:
1, as long as driving engine is in running order, no matter which kind of gear it is positioned at, and agricultural machinery uses this device all can obtain power;
2, simple in structure, low cost of manufacture, installation, maintenance is convenient;
3, magnetic clutch carries belt pulley, compact conformation not only, and also simple to operate, easy to use;
4, with each agricultural machinery bonded assembly mlultiple-groove sheave be positioned at the vehicle frame rear portion, be convenient to after drag the various agricultural machinery in the railway carriage or compartment to be connected, easy to implement.
