Block-resistant type potato picker
Technical field
The utility model is related to technical field of agricultural machinery, and in particular to a kind of block-resistant type potato picker.
Background technology
In recent years, potato planting industry development is very fast, and yield rises year by year, produces huge economic benefit.At present
The potato in China is mainly excavated using hand digging and semi-mechanization, and domestic many potato harvesters are directly will
After potato is dug out, it is allowed to be returned in field together with stalk, mulch etc., then human hand work point to be leaned on to pick up, labor intensity is very
It is huge.Therefore, the development of Potato Industry is limited to a certain extent.This excavation mode is fallen in mining process simultaneously
Under soil potato, stalk and mulch etc. can be buried in the fields, bring economic loss to peasant, also give peasant with
Labour burden additionally is carried out.
