Bundling machine making cotton straw bundle used for processing high water content mud and novel dredger fill

The invention relates to a bundling machine making cotton straw bundles used for processing high water content mud and novel dredger fill; the bundling machine comprises a feeding mechanism, a bundle forming room and a binding mechanism; the bundle forming room comprises a left half die and a right half die; the left and right half dies can be matched to form a cylinder straw bundle forming zone; inner surfaces of the left and right half dies are respectively provided with a plurality of rollers; the roller has a circumferential groove, and the grooves of the rollers are spliced to form a guide rail; a packing tape of the binding mechanism runs along the guide rail; two ends of the straw bundle forming zone are respectively provided with a front cover and a rear cover; the front cover can make axial reciprocating motions along the straw bundle forming zone; the rear cover can rotate to open/close, and serves as a discharge door of the straw bundle forming zone; the center positions, at the opposite sides, of the front cover and the rear cover are provided with bosses and concaves matched in shape; the bundling machine can very conveniently make cylinder cotton straw bundles, thus reducing production cost.
