Description
Technical field
The utility model relates to rotovator field of mechanical technique, especially a kind of damping column of rotovator.
Background technology
Rotovator completes cultivated, to harrow operation cultivation machinery.Because of its have hack ability strong, plough after the features such as earth's surface is smooth, and to be widely used.Proper use of and adjustment rotovator, to maintenance its good technique state, guarantee that cultivating quality is very important.
In farming activities, front required step is cultivated in rotary tillage, only has after soil is carried out rotary tillage and just can sow.In prior art, usual employing hand-held rotovator, its cost is low, easy to operate, rolled by Rotary tillage blade and advance, effective rotary tillage is carried out to harder plot, but in rotary tillage process, operator cannot ensure rotary tillage on same linear position soil, and the adjustment depth that can not suit measures to local conditions, brings inconvenience to rotary tillage.
Applicant, in having applied for that name is called " the damping column mounting structure of rotovator " on the same day, utilize the orientation of rearmounted damping column, solve the problem of directed rotary tillage, and damping column can carry out Height Adjustable, is convenient to different depth rotary tillage.The shortcoming that damping column in above-mentioned patent also exists is: when damping column is inserted in subsurface, and friction between earth block is comparatively large, causes surperficial heat higher, increase the energy consumption of rotovator on the one hand, damping column is easy to wear on the other hand, occur surface division, and single damping column easily offsets.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of drag reduction formula damping column of rational in infrastructure, rotovator that resistance is little, thus reduce rotovator energy consumption, improve rotary tillage efficiency.
The technical scheme that the utility model adopts is as follows:
A drag reduction formula damping column for rotovator, comprises damping column body, and described damping column body is plate like structure, and its top is with multiple installing hole side by side up and down, and bottom is with the bifurcated board plug structure be made up of front card and back card/back board; The arcuate structure bent on front side of the oriented damping column body of described front card band, back card/back board tilts to the rear side of damping column body; The both sides of described front card are with front guiding gutter, and the both sides of back card/back board are with rear guiding gutter.
Further improvement as technique scheme:
The extrados side of front card is with multiple gear shaping arranged along cambered surface.
The extrados of described front card is with the separate slot extended along cambered surface.
The lower end of the through front card of described separate slot.
Described front guiding gutter is curved slot arrangement, and its cancave cambered surface is towards the front side of damping column body.
The leading flank of the through damping column body in upper end of described front guiding gutter.
Described rear guiding gutter is curved slot arrangement, and its cancave cambered surface is towards the rear side of damping column body.
The through trailing flank of damping column body and the lower surface of back card/back board respectively, two ends up and down of described rear guiding gutter.
The beneficial effects of the utility model are as follows:
Structure of the present utility model is simple, it is easy to process to manufacture; Adopt dichotomous front and back board plug structure, keep straightaway during rotary tillage, its efficiency is high; The guide trough structure of gear shaping and separate slot and front and back plate is set, reduces the frictional force between damping column side and mud ground, reduce the degree of wear, reduce rotovator energy consumption.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Wherein: 1, damping column body; 2, installing hole; 3, back card/back board; 4, front card; 41, gear shaping; 42, separate slot; 5, front guiding gutter; 6, rear guiding gutter.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the drag reduction formula damping column of the rotovator of the present embodiment, comprises damping column body 1, and damping column body 1 is plate like structure, and its top is with multiple installing hole 2 side by side up and down, and bottom is with the bifurcated board plug structure be made up of front card 4 and back card/back board 3; The arcuate structure of front card 4 with bending on front side of oriented damping column body 1, back card/back board 3 tilts to the rear side of damping column body 1; The both sides of front card 4 are with front guiding gutter 5, and the both sides of back card/back board 3 are with rear guiding gutter 6.
The extrados side of front card 4 with multiple gear shaping 41 arranged along cambered surface and the separate slot 42 extended along cambered surface, the lower end of the through front card 4 of separate slot 42.Gear shaping 41 and separate slot 42 water be convenient to above by front card 4 is directed into below, reduces frictional resistance.
Front guiding gutter 5 is curved slot arrangement, its cancave cambered surface towards the front side of damping column body 1, the leading flank of the through damping column body 1 in upper end of front guiding gutter 5.When front card 4 is advanced, the upper end of the water the past guiding gutter 5 on front side of it enters and flows out from the side of the front card 4 of lower end, reduces frictional resistance.
Rear guiding gutter 6 is curved slot arrangement, and its cancave cambered surface is towards the rear side of damping column body 1, and the trailing flank of through damping column body 1 and the lower surface of back card/back board 3 are distinguished in the two ends up and down of rear guiding gutter 6.When back card/back board 3 is advanced, the earth on its travel track opens to both sides, current on rear side of the track after opening to front side flow, thus enter from the upper end of rear guiding gutter 6 and from lower end flow out, its water guide is effective.
When the utility model uses, damping column body 1 is installed in frame by installing hole 2, and its front card 4 and back card/back board 3 are inserted in subsurface; When damping column is advanced, the water of mire is directed into bottom and both sides from guiding gutter 5 before the gear shaping gap of front card 4 and separate slot and both sides, water simultaneously above back card/back board 3 enters its side and bottom from rear guiding gutter 6, thus the frictional force reduced between damping column side and mud ground, reduce the degree of wear; Because front and back plate is plate like structure, realize straightaway during rotary tillage.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
