Straw grid transverse laying device and method for sand stabilization machine

The invention discloses a grass grid transverse laying device and method for a sand stabilization machine, the device comprises a grass feeding mechanism, a grass cutting mechanism, a grass hooking mechanism, a sliding supporting mechanism, a slotting tool mechanism and an overall moving mechanism, the grass hooking mechanism slides along the sliding supporting mechanism, and the slotting tool mechanism and the grass feeding mechanism are arranged on the sliding supporting mechanism; a grass cutting mechanism is arranged on the lower portion of the grass conveying mechanism, and the overall moving mechanism intermittently drives the whole transverse laying device to move relative to a chassis of the sand stabilization machine, so that a relative static state is formed among the slotting tool mechanism, the to-be-laid straw mat section and the to-be-laid sand. The method comprises the following steps: after the grass conveying mechanism releases a grass curtain, the grass curtain is hooked by the grass hooking
