Double-rolling brush type seedling trimming mechanism configured on solanaceae automatic grafting machine

The invention discloses a double-rolling brush type seedling trimming mechanism configured on a solanaceae automatic grafting machine and belongs to gardening vegetable seedling culture, production and grafting equipment. A height position adjustment motion assembly is fixedly arranged on a longitudinal insertion motion assembly, a transverse spacing adjustment motion assembly is assembled on the height position adjustment motion assembly, two transverse opposite side parts of the transverse spacing adjustment motion assembly are respectively provided with a motor, two axle type rolling brush rolls are parallel to each other and are respectively assembled on the motors at two sides in horizontal cantilever structures, supporting plates provided with strip-shaped slideway supporting holes are configured on the outer sides of the cantilever tail ends of the axle type rolling brush rolls, and the tail ends of the two axle type rolling brush rolls and the strip-shaped slideway supporting holes on the supporting plates are in inserting and supporting fit or separate fit. The double-rolling brush type seedling trimming mechanism can effectively remove vegetable seedling cotyledon by rows at high speed, and has the characteristics of simple structure, reliable running, simpleness and convenience in operation, and high success rate of grafting.
