Spiral grape vine burying machine

The invention relates to a spiral grape vine burying machine, which belongs to the field of agricultural machinery and comprises a machine frame unit, a spiral rotary cultivation soil conveying unit, an impeller soil throwing unit and a motive power transmission unit, wherein the spiral rotary cultivation soil conveying unit completes the soil rotary cultivation and the right single side conveying work through the simultaneous effect of a right cutter blade, a back baffle plate and a soil guide plate in spiral arrangement, the structure is simplified, the power consumption is also reduced, and in addition, the cultivated earth surface is flat; and the impeller soil throwing unit completes the throwing work of soil conveyed by the spiral rotary cultivation soil conveying unit through the counterclockwise rotation of an impeller, the soil can be accurately and intensively thrown to the grape vine position through regulating the soil throwing and soil lifting angle and a soil throwing baffle plate, and the vine burying effect is reached. Because the modular design is adopted, the machine has the advantages that one machine has multiple purposes, after the whole impeller soil throwing unit and the corresponding motive power transmission system are dismounted, the furrowing and soil cleaning operation can be carried out, the spiral grape vine burying machine can also be used as a rotary cultivator through changing the blade installing mode, and the utilization rate of the machine is improved.
