Background

For a long time, the treatment of tobacco straws mainly adopts the extensive modes of field discarding, burning, cooking by fire, burning and warming and the like, and a reasonable resource utilization means is lacked. Although resource utilization approaches such as granular formed fuel and biological carbonized fertilizer taking tobacco straws as raw materials appear in recent years, the tobacco straws are directly transported to a processing field from the field, and the resource utilization popularization speed of the tobacco straws is severely restricted due to the scattered distribution of the tobacco straws, time and labor waste and high transportation logistics cost. Therefore, there is a need for a device that can cut tobacco stalks into pieces, compress them into bales, and facilitate transportation.

In addition, the plant stems of tobacco stalks, which have the same chemical components as the main chemical components of wood materials and a high lignin content, are required to be preheated to soften and melt the lignin contained therein to become binders (qianxiang, research on the characteristics of stalk cutting and compression molding and equipment research [ D ] zhejiang university, 2003) for molding.
