发明名称 Rotary weed extractor
摘要 A tool for extracting weeds without stooping, bending or personally touching the weed is disclosed. The weed extracting tool has a plurality of spikes mounted onto a block which is mounted onto the lower end of a torque bar. Spiral ribs on the spikes are force fitted within bores formed in the block resulting in an interlocking union. A spring-loaded ejector carriage is movably mounted onto the torque bar for movement between retracted and extended positions. The ejector carriage includes an ejector plate, a push plate, and side panels connecting the two plates. The ejector plate is interposed between the spikes. A weed is extracted from the soil by inserting the spikes into the ground around the central root core of the weed, rotating the torque bar to engage the weed's roots about the spikes, and then lifting the entangled weed from the ground. The weed is then expelled by manually extending the ejector carriage along the torque bar.
