Shellfish soil excavating device of fritillaria ussuriensis bulb harvester

Technical Field

The invention relates to the field of fritillaria bulb harvester, in particular to a shellfish soil excavating device of a fritillaria bulb harvester.

Background

As fritillary bulb grows in soil, when the fritillary bulb harvester works, mechanical equipment is needed to be inserted into the furrow soil for digging, a fritillary soil mixture mixed with the furrow soil and the fritillary bulb is dug out together, the fritillary soil mixture is lifted to a certain height by the lifting device and conveyed to the separation device, and fritillary soil separation is realized. According to the standardized planting requirement of fritillaria ussuriensis, a topping feces layer and a covering soil layer are further arranged on the fritillaria ussuriensis bulb breeding layer, and the topping feces is an organic fertilizer and is a necessary fertilizer for growth of fritillaria ussuriensis. The covering soil layer is generally humus soil with loose soil quality and good drainage. The good cyclic utilization of the head covering manure layer and the soil covering layer is beneficial to the periodic growth of fritillaria ussuriensis. Therefore, the cap excrement layer and the soil covering layer cannot be taken away in the harvesting process, and high-quality soil loss is caused. If the mulch excrement layer and the soil covering layer are excessively present in the shell-soil mixture, the heavy burden is added to the shell-soil screening work after the shell-soil mixture enters the screening device, and the harvesting efficiency of the whole machine is affected. Therefore, the shellfish soil excavating device of the fritillaria ussuriensis bulb harvester is designed.
