Horizontal balancing unit of seedling case

The utility model provides a horizontal balancing unit of seedling case, including the seedling case, the middle part of seedling case is provided with the seedling case support frame seam that is used for supporting the seedling case, and the left and right sides symmetry of seedling case support frame seam is provided with the transverse connection pole of seedling case support frame seam, parallel and be provided with balanced hydro -cylinder between two transverse connection poles with the seam of seedling case support frame, is provided with hydrocushion oil cylinder piston rod in keeping balance the hydro -cylinder, and the transverse connection pole is connected through elastomeric element with hydrocushion oil cylinder piston rod. The utility model provides a horizontal balancing unit of seedling case is provided with and is used for compensating small unbalanced elastomeric element, connects seam of seedling case support frame and hydrocushion oil cylinder piston rod through elastomeric element, and compensation hydrocushion system is because the slope volume of the seedling case that reduces to bring of balanced feedback speed keeps seedling case balance when critical balance point to it is unanimous basically to make the seedling case left and right sides transplant rice seedlings the degree of depth, the obvious effectual improvement quality of transplanting rice seedlings.
