Description
Technical field
The present invention relates to agricultural machinery equipment technical fields, and in particular to a kind of drum-type potato harvest with diversion trench
Machine array excavating gear and method for digging.
Background technique
Developed country and the Northeast, China large area potato harvest mostly use high-power self-propelled combining at present
Machine, can once complete climber cutting, dig cut, native potato separation, size fractionation, pack, transport etc. operate, though powerful, its function
Consumption is high, is not suitable for the middle-size and small-size plot that China mountainous region is more, the gradient is big, cultivated area is small.
The potato harvest equipment that the current Mountainous areas in China uses, general usage mining shovel are cut at a certain angle
Soil and potato shovel are dug out and are delivered on swing separation sieve by soil, the vibration, friction the effects of under reach potato with
The effect of soil separation.Because power is small, digger blade cutting depth of soil is limited, easily causes the mechanical damage of potato, drops
Low potato economic value, and the potato discharge cropper after swing separation sieve separation is randomly dispersed in earth's surface, needs artificial
It picks up and collects, be unfavorable for subsequent potato digger tool.
Drum-type potato cropper (application publication number CN105993357A/ application number 201610316344.2) is one
Potato is separated and is transmitted out by spiral strainer the machinery of earth's surface from soil using shake or the principle hit by kind,
It is mainly designed for the tuber crops such as the potato in the clayed soil of knob harvest.In the program, drum-type potato
The operation in clayed soil of cropper excavating gear, clayed soil can be adhered in tool surface and cutter mounting structure, cause
Tool in Cutting power reduces cutting resistance and increases, and harvest mechanomotive force increases, and the tuber crops such as potato is hindered to enter later separation
In screening plant, operating efficiency decline.
Summary of the invention
The drum-type potato of being solved cropper operation in clayed soil of the invention, clayed soil can be adhered to cutter
It in surface and cutter mounting structure, causes Tool in Cutting power to reduce cutting resistance and increases, harvest mechanomotive force increases, and hinders potato
The problems such as equal tuber crops enter in later separation screening plant, and operating efficiency declines, design that a kind of power consumption is small, structure
Simply, potato mechanical damage is low, excavating gear suitable for drum-type potato cropper.
In order to solve the above technical problems, the drum-type potato cropper array designed by the present invention with diversion trench excavates
Device, it is characterised in that: it includes cutter mounting frame and multiple cutters, wherein the cutter mounting frame include circular ring shape frame body,
