Drum Potato Harvester

Abstract

The invention relates to a drum type potato harvester. The drum type potato harvester comprises a fixed framework, a rotating shaft, a filter screen framework, an annular soil cutting blade, blades, a spiral filter screen, wheels, a limiting cross rod and an angle adjusting rack, wherein the filter screen framework is fixed on the rotating shaft, the annular soil cutting blade is fixed at the front end of the filter screen framework, the blades are fixed at the middle part of the rotating shaft, the spiral filter screen is circumferentially and fixedly nested in the filter screen framework, the wheels are arranged at one end of the fixed framework, the limiting cross rod is fixed at the other end of the fixed framework, and the angle adjusting rack is arranged on the fixed framework; and one end of the rotating shaft is in rotary connection with the angle adjusting rack, the other end of the rotating shaft penetrates through a through hole in the limiting cross rod, the rotating shaft is in rotary connection with the through hole, and a tractor power connecting member is further arranged at the other end of the rotating shaft. The drum type potato harvester has the advantages that the power consumption is low, the structure is simple, and the mechanical damage to potatoes is low.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a drum-type potato harvester. technical background [0002] At present, large-scale potato harvesting in developed countries and Northeast my country mostly uses high-power self-propelled combine harvesters, which can complete operations such as vine cutting, digging, soil and potato separation, size grading, bagging, and transportation at one time. Its power consumption is high, and it is not suitable for small and medium-sized land plots with many mountains, large slopes, and small planting areas in my country. [0003] Potato harvesting equipment currently used in mountainous and hilly areas in my country generally uses digging shovels to cut the soil at a certain angle, digs out the soil and potato shovels and transports them to the swinging separation screen, and achieves the effect of separating potatoes from soil under the action of vibration and friction . ...

AI Technical Summary

Problems solved by technology

Due to the low power, the digging shovel cuts the soil to a limited depth, which can easily cause mechanical damage to the potatoes and reduce the economic value of the potatoes, and the potatoes separated by the swing separator are randomly scattered on the ground, requiring manual picking and collection, which is not conducive to subsequent potato collection.
