the conveying and collecting chain consists of a front lower chain and a rear upper chain, the front lower chain and the rear upper chain are arranged in parallel, and the front lower chain conveys the lower part of the hemp tip to the right side;
the rear upper chain consists of a rear left upper chain and a rear right upper chain, the rear left upper chain and the front lower chain are in the same speed and direction, and the hemp tips are conveyed to the right side to form a lateral conveying and collecting chain;
the direction of the rear right upper chain is opposite to that of the front lower chain, and the hemp tips are rotated leftwards and transversely laid on the conveying belt to form a reverse conveying and collecting chain; the conveying belt is a wide belt;
the driving box comprises a cutting knife driving crankshaft, a lateral conveying and collecting chain driving shaft, a reverse conveying and collecting chain driving wheel shaft, a box body and an input wheel shaft, and transmits power to the cutter and the conveying and collecting chain;
the input wheel shaft drives a cutting knife to drive a crankshaft through a bevel gear, the output end of the cutting knife driving crankshaft is connected with two pairs of crank-link mechanisms which directly drive an upper cutting knife and a lower cutting knife, and a cylindrical gear on the cutting knife driving crankshaft drives a lateral transmission and collection chain driving shaft in a speed reduction mode;
the front end of the lateral transmission and collection chain driving shaft directly drives the front lower chain, and the rear end of the lateral transmission and collection chain driving shaft drives the rear left upper chain through the transmission chain;
the reverse conveying and collecting chain driving wheel shaft is driven by a cylindrical gear on a cutting knife driving crankshaft through a wheel, and directly drives the reverse conveying and collecting chain to realize reverse speed increasing with the lateral conveying and collecting chain.
