Device and process for cutting grass sods with a constant thickness from grass land

摘要

A method and apparatus for cutting a grass sod from a grass land are disclosed. The apparatus includes a cutting blade positioned between a front end and rear end of a sod cutting apparatus. An adjusting mechanism adjusts the position of the cutting blade to cut the grass sod a predetermined distance below a surface of the grass sod. A measuring mechanism measures a profile of the grass sod to be cut from the grass land and/or a thickness of the cut grass sod. A controller is connected to the measuring mechanism and the adjusting mechanism. The controller causes the adjusting mechanism to adjust the position of the cutting blade in response to the measuring mechanism detecting changes in the profile of the grass sod to be cut from the grass land and/or the thickness of the cut grass sod. The method includes setting a cutting blade to cut from the grass land the grass sod having the predetermined thickness. During cutting of the grass sod from the grass land, a profile of the grass sod and/or a thickness of the cut grass sod is determined. In response to detecting variations in the profile and/or the thickness of the cut grass sod, the cutting blade is adjusted to maintain the cut grass sod at the predetermined thickness.
