Abstract
The invention discloses a kind of tomato digging part with bionical broached-tooth design, the purpose is to solve the problems, such as the existing big high energy consumption of digging element resistance；Include shovel body, shovel body is made up of two shovel faces, two open-shaped states of shovel face, the angle α between two shovel faces be 120 °~140 °, be provided with shovel face the first shovel refer to, second shovel refer to, the 3rd shovel refers to, the 4th shovel refers to and refers to the 5th shovel；First shovel refers to, the second shovel refers to, the 3rd shovel refers to, the 4th shovel to refer to and refer to the sawtooth of front outer profile for isosceles triangle with the 5th shovel, and five shovels refer to that front end face intersection angle beta is identical, β=100 °~120 °.The present invention can significantly reduce tractive resistance in digging operation, can reduce Cutting Drag, improve operating efficiency.
Description
Technical field
The present invention relates to the digging element in agricultural harvesting machinery, the more particularly to cutting of the root crop such as potato class is excavated
Part, belongs to agricultural mechanical field.
Background technology
Root crop（Such as potato, Ipomoea batatas）Excavation be these crop harvestings important procedure, digging element
Performance directly affects digger of potatoes and integrally excavates performance.It has stronger hack ability to digging element design requirement, while
Can as far as possible it is few take soil in the case of by potato wedges turn up, and prevent from shoveling upper straw winding and hilling.Existing tomato digging shovel
The mostly pattern of plane shovel piece, cutting edge is not smooth wear-resisting, and hack ability is poor, and tractive resistance is big, and operation power consumption is higher.Therefore,
To ensure the working condition of its stabilization, rational service life and its performance driving economy, it is necessary to wearability is high, cutting performance is good
Good, energy consumption is low, efficiency high digging element.The trapping organs of some animals can ensure that it in cutting by different architectural features
With produce relatively low resistance and power consumption in mining process, and this cut-away process has necessarily with the operation process of tomato digging part
Similitude.As mantis front foot has excellent cutting performance, the saw tooth shaped structure that its front foot tibia outer rim has, abnormal cutting edge of a knife or a sword
Profit, rapidly impact cutting can be pierced into prey body in predation；Mole is referred to as " excavator " of work, with efficient mining ability,
Its fore paw overall structure is in spade, is main excavation organ.The cutting of above-mentioned animal is with the structure for excavating organ for potato class are dug
The drag reduction Synergistic structure design for digging part provides bionics foundation.
The content of the invention
It is an object of the invention to provide a kind of tomato digging part with bionical broached-tooth design, the present invention is in digging operation
When can relatively significantly reduce tractive resistance, improve its operating efficiency.
Imitate the zigzag geometry of mantis front foot tibia outer rim body thorn, mole front foot and excavate pawl toe structure, design tool
There is the tomato digging part of bionical broached-tooth design, including imitate mole fore paw pawl toe form and the architectural feature being distributed, design is dug
Dig the shovel face monnolithic case structure of part；The zigzag form of mantis front foot tibia body thorn is imitated, design digger blade refers to outer rim
Zigzag cutting edge contour.Digging element overall profile design reference organism structure morphological feature.
The present invention includes shovel body, and shovel body is made up of two shovel faces, two open-shaped states of shovel face, between two shovel faces
Angle α be 120 °~140 °, the length W=180mm~200mm of shovel face is provided with that the first shovel refers to, the second shovel refers to, the in shovel face
Three shovels refer to, the 4th shovel refers to and refers to the 5th shovel；The length that the 3rd middle shovel refers to is L2, and the first shovel refers to, the second shovel refers to, the 4th shovel refers to
The length referred to the 5th shovel is L1, L2/L1=1.1~1.2；Spacing between adjacent shovel refers to is H, 25mm≤H≤35mm；
3rd shovel refers to front outer sawtooth land lengthl2 are with the ratio of its total length L 2l2/L2=0.4~0.6, the first shovel refers to, the
Two shovels refer to, the 4th shovel to refer to and refer to front outer sawtooth land length with the 5th shovell1 ratio for referring to total length L 1 with shovell1 /L1=0.4
~0.6；
First shovel refer to, second shovel refer to, the 3rd shovel refers to, the 4th shovel refer to the 5th shovel refer to front outer profile sawtooth be isosceles
The ratio between triangle, the tooth h high and shovel finger widths M of sawtooth h/M=0.1~0.3；First shovel refers to, the second shovel refers to, the 3rd shovel refers to, the
Four shovels to refer to and refer to that front end face intersection angle beta is identical with the 5th shovel, β=100 °~120 °.
Beneficial effects of the present invention：The present invention can significantly reduce tractive resistance in digging operation, can reduce cutting
Resistance, improves operating efficiency.
