Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Oryza sativa L. spiral feed mechanism for seed as shown in Figures 1 to 6, including housing 1, plant case 2, discharging tube 3,
Seed wheel 4 and rotating shaft 5, the top and bottom of described housing 1 are respectively equipped with sow mouth 6 and sowing port 7；
Described kind of case 2 and discharging tube 3 respectively with sow mouth 6 and sowing port 7 is connected；Described seed wheel 4 passes through
Rotating shaft 5 is installed in housing 1, and institute's seed wheel 4 is being sowed between mouth 6 and sowing port 7；Described
The circumferential wall of seed wheel 5 is provided with a plurality of helicla flute 8.Concrete, as shown in Figure 6 and Figure 7, helicla flute 8
Rotate relative to the axis of seed wheel 4, and a plurality of helicla flute 8 is equal relative to the circumference of seed wheel 4
