The second brad nail transmission chain row 31 is arranged along the feeding direction of the automatic cotton and hemp stalk feeding machine in a downward inclination mode, and second brads 311 used for pushing cotton and hemp stalks at the bottom layer to move forwards along the feeding direction are arranged on the second brad nail transmission chain row 31; the intermittent reverse-pulling roller 32 is rotatably arranged above the second brad nail transmission chain row 31 and is positioned at the front end of the second brad nail transmission chain row 31, the working surface of the intermittent reverse-pulling roller 32 is less than or equal to half of the outer surface of the intermittent reverse-pulling roller 32, and the rotating direction of the intermittent reverse-pulling roller 32 is opposite to the advancing direction of the second brad nail transmission chain row 31.
After thinning, the overlapping thickness of the cotton and hemp stalks is effectively thinned, however, because the cotton and hemp stalks are hard wood materials, the layering is difficult and the mutual entanglement between the cotton and hemp stalks is more prominent, and because the first brad drive chain row 21 is a semi-flexible chain row, a plurality of cotton and hemp stalk layers which are overlapped thickly enter the second brad drive chain row 31 inevitably. In this embodiment, an intermittent reverse-pulling roller 32 is installed above the second brad nail transmission chain row 31, the working surface of the intermittent reverse-pulling roller 32 is less than or equal to half of the outer surface of the intermittent reverse-pulling roller, and the working surface is formed by embedding triangular iron strips on an arc-shaped wood board and fixing the triangular iron strips on the entity of the wave-pulling roller by screws. The intermittent reverse-raking roller 32 is driven by a speed reducer through a chain transmission mechanism, and the rotating direction of the intermittent reverse-raking roller 32 is opposite to the advancing direction of the cotton and hemp stalks, so that the working surface of the intermittent reverse-raking roller 32 can slowly and reversely rake the overlapped and redundant cotton and hemp stalks, the cotton and hemp stalks which are regularly and relatively moved backwards are enabled to be prevented from being disordered, meanwhile, the bottom layer cotton and hemp stalks which are in contact with the second corner nail transmission chain row 31 can be ensured to synchronously advance at the operating speed of the second corner nail 311, and obvious dislocation and abnormal movement can not occur.
