A double-table-board working table suitable for tobacco leaf grading is characterized in that the double-table-board working table suitable for the tobacco leaf grading comprises two table-board working tables, wherein the two table-board working tables are arranged oppositely and are respectively formed by frame-type supporting legs and a tobacco leaf grading table-board. Each tobacco leaf grading table-board is formed by a horizontal table top, an inclined-type table top and a top end table top together, each inclined-type table top is adjustable in inclined degree and is hinged to the corresponding horizontal table top, the upper edge of each inclined type table tops is correspondingly connected with one side edge of the top end table top in a hinged mode, the width of the two horizontal table tops is 5-10cm, the two horizontal table top can both move back and forth on sliding ways arranged on the two sides of the frame, a baffle is arranged on the front edge of each horizontal table top, the height of the baffles is 3-5cm, and the inclined degrees of the two inclined type table tops are adjusted through the ascending and the descending of a support below the top end table top. Through the double-table-board working table suitable for the tobacco leaf grading, the surfaces of tobacco leaves can be adjusted to be in angles, the technological requirement of the included angle between light rays and the vertical direction of the surfaces of the tobacco leaves is met, the accuracy of the results of the tobacco leaf grading is improved, the comfortableness of people in working is increased greatly, and working efficiency is improved.
