WIPO Patent Application WO/2011/038638
Kind Code:
A1
Abstract:
An airflow brush for filling sand and a sand filling device are provided. The airflow brush comprises a housing (10), two rows of brushes (210,220) respectively located on the front side and rear side of the bottom of the housing to sweep the sand on the ground, and a travel mechanism located on the bottom of the housing. The housing is a tank structure whose middle is a hollow cavity (130) and whose bottom is an opening. The top surface of the housing is provided with a holding frame (110) for putting and fixing an airflow generating device and an air intake (120) for the airflow entering into the hollow cavity. The sand filling device comprises the airflow brush for filling sand and a blower (40) mounted on the airflow brush for filling sand to provide airflow. The airflow generated by the blower is introduced into the hollow cavity of the housing and impacts in the hollow cavity to form strong airflow so as to blow the sand into the holes, thus ensuring the uniformity of the sand. The sand filling device avoids manual operation, greatly saves labor, and mechanization operation thereof ensures that the sand is efficiently filled back into the holes, thus reducing damage to the lawn.
