Description

Technical Field

[0001] The invention relates to the technical field of turf cutting, in particular to a cutting device capable of cutting turf in multiple grids. Background Art

[0002] Turf refers to the green plants in square green spaces, alpine meadows and flat areas. It is widely used. Before laying the turf, it needs to be cut into corresponding sizes and shapes according to the actual site requirements. In the process of cutting the turf, the traditional manual cutting is time-consuming and labor-intensive, so a turf cutting device is needed.

[0003] The existing Chinese utility model patent with reference announcement number: CN215912755U discloses an adjustable-size agricultural turf cutting device, including a fixed mounting plate, a scale code is arranged in the middle of the front side of the fixed mounting plate, a fixed connection column is provided with fixed grooves with a limiting function at equal intervals on one side of the vertical central axis of the fixed mounting plate, the fixed connection column is symmetrically arranged at the left and right ends of the fixed mounting plate, the limiting mechanism is arranged at the lower end of the fixed connection column in a "T"-shaped structure, and a fixed connection rod in a "U"-shaped structure and with threads arranged on the outer surface is inserted in the middle of the fixed connection column. The adjustable-size agricultural turf cutting device is convenient for adjusting the cutting size of the turf according to the actual site usage requirements, and the fixed connection column is convenient for limiting the position through the first connection sleeve and the second connection sleeve, and the cutting height of the cutting blade is convenient for adjusting through the setting of the limiting mechanism.

[0004] When in use, the existing turf cutting device generally cuts the turf vertically downward with a cutter. Since the device moves forward in unison, the cutter may not be able to move forward synchronously after moving downward and contacting the soil due to obstruction of the soil. The cutter may bend or even break. At the same time, the existing cutting device cannot perform a second cut on the scooped turf, and the turf needs to be cut into sections to a suitable size later, which is very inconvenient.
