发明名称 ROOFING MATERIAL REMOVAL DEVICE
摘要 A material removing device for removing materials from a surface includes a body having a handle assembly with a recoil mechanism and a driver slidably mounted to the body. A blade with a slotted edge is removably connected to the driver. An actuator mounted to the body provides a high impact to the driver to slide the blade in the longitudinal direction under the materials to be removed and then pivot the blade upward to pry the materials from the surface. The actuator can be pneumatically powered and activated by a manual or automatic trigger. The device is designed to be used as a hand held roofing tool and exhibits light weight and easy operation.
