Root crop combine harvester

Abstract

The invention relates to a couple harvester of root and stem crops, comprising a walking chassis, a main frame mounted on the chassis, a harvest table hinged with the main frame, a digging shovel on the harvest table, a soil separator and a separator at the back of digging shovel, and a clamping transmitter above the digging shovel, the soil separator and the separator. The invention is characterized in that the separator is blade roller separator or disc cutting separator, therefore, the invention can harvest kinds of stem and root crops, as peanut, toasted garlic, or the like.

Description

technical field [0001] The invention relates to an agricultural crop harvesting machine, in particular to a combine harvester applicable to various rhizome crops such as peanuts, garlic, and onions, and belongs to the technical field of agricultural machinery. Background technique [0002] In recent years, with the adjustment of my country's agricultural industrial structure, the planting area of ​​peanuts, garlic, onions and other root crops has been expanding. At present, operations such as soil preparation, sowing, cultivating soil, spraying and other operations in the production process of such crops have been basically mechanized, but the mechanization level of harvesting is relatively low. One of its main reasons is that existing rhizome crop harvester is only suitable for harvesting a kind of root crop, such as peanut combine harvester can only be used for harvesting peanuts. However, there are many types of rhizome crops, and the planting area of ​​a single type of ...

AI Technical Summary

Problems solved by technology

At present, operations such as soil preparation, sowing, intertillage, spraying and other operations in the production process of such crops have been basically mechanized, but the mechanization level of harvesting is relatively low.

One of the main reasons is that the existing root crop harvesting machines are only suitable for harvesting a kind of root crops, for example the peanut combine harvester can only be used for harvesting peanuts

However, there are many types of rhizome crops, and the planting area of ​​a single type of crop is relatively small. Therefore, the annual operation volume of machinery and tools is small, and the cost of use is high, which restricts the development of mechanized harvesting.

[0003] The combined harvester for rhizome crops integrates the functions of excavation, soil removal, separation, cleaning, and collection. The main reason why the existing models cannot realize the multi-purpose of one machine is that it is only fixedly equipped with a separation device for separating stems, leaves and fruits. mechanism

Since the structure, shape, size and difficulty of separating the stems, leaves and fruits of different types of root crops are different, only one separation mechanism cannot meet the mechanized harvesting requirements of various root crops at the same time.
