height-adjustable lawn mower

Abstract

The invention discloses a height-adjustable hay mower. The hay mower includes a hay mower body, grass crushing devices and a height adjustment device which is used for adjusting the heights of the grass crushing devices; the height adjustment device is fixedly installed on the hat mower body, and the grass crushing devices are installed on the height adjustment device, located on the two sides of the hay mower body and used for collecting cut grass, crushing the cut grass and then sending the crushed grass to a garden plot. In the height adjustment process, a lifting motor is connected with a first electric push rod and drives the first electric push rod to move up and down, and a power transmission plate fixed on the first electric push rod moves up and down along with the first electric push rod, so that the heights, relative to the bottom of a hay mower frame, of the grass crushing devices are adjusted; when the grass crushing devices work, a draught fan produces negative pressure at grass suction holes, the cut grass enters a grass collection tank through the grass suction holes and then enters a grass crushing bin under the action of a smooth inclined plane, grass crushing cutters located on the bottom of the grass crushing bin crush the cut grass, and the crushed grass is discharged from grass outlet channels under the action of the fan.
