This invention relates to the field of garden maintenance technology and discloses an integrated device for collecting and crushing fallen leaves in gardens. The device includes a carrier, a negative pressure leaf suction machine mounted on the front of the carrier, and a crusher mounted on the rear of the carrier. A separation tank is installed on the carrier between the negative pressure leaf suction machine and the crusher via a leveling mechanism. The discharge port of the negative pressure leaf suction machine is positioned directly above the separation tank. The separation tank contains liquid and a washing module is installed within it. The washing module is used to wash the fallen leaves that fall into the liquid in the separation tank and then feed them into the crusher.
