Abstract
Disclosed is a straw returning rotary cultivator free of winding grass. A rotary blade of the rotary cultivator consists of a vertical coulter 5 and a horizontal coulter 6, the horizontal coulter 6 is in the shape of long rod, two ends of the horizontal coulter 6 are fixed on two adjacent tail end portions of the vertical coulter 5, the fixed direction and the rotation direction of the horizontal coulter 6 form an acute angle, and the inner side of the horizontal coulter 6 is provided with an earth scarifying blade 8. The rotary cultivator can not only improve strengths of coulters and prolong service life, but also press straws and weeds into the earth to avoid winding onto coulter shafts, thereby achieving fine earth scarifying capacity without increasing power loads and enabling cultivated fields to be more flattened. Simultaneously, a grass resistant device is further arranged to avoid straws and weeds entering into gaps of shaft ends and to protect a machine. Further, the rotary cultivator with simple structure can achieve the purpose of returning straws to fields without winding grasses by the means of simple alternation on a prior rotary cultivator, thereby being applicable to promotion and application in rural areas.
Description
Technical field
The utility model relates to a kind of farm machinery structure, is meant a kind of rotovator structure specifically.
Background technology
Crops such as paddy rice, corn, wheat etc. adopt straw-returning, not only help soil moisture conservation, and can also provide fertilizer for next batch crop, increase soil fertility, and reduce the use of chemical fertilizer.Present rotovator structure connects power transmission box by gear-box, drive cutter shaft and some rotary blades rotation carrying out rotary tillage, the rotary tillage cutter adopts the tulwar tool more, when carrying out farming, long stalk and weeds can twine on the cutter shaft, on the joint portion of cutter shaft and support arm and power transmission box, cause rotary tillage efficient to reduce, even rise and split support arm and damage machine.For reaching the straw-returning purpose, need and to carry out rotary tillage again after stalk and the weeds chopping, a kind of method is to adopt artificial chopping, and this method labour intensity is big, is not easy to promote, other method is to install or change the chaffcutter dedicated tool on rotovator additional, to carry out rotary tillage again, this method complex structure, cost height after stalk and the weeds chopping earlier, use trouble, also be unfavorable for promoting.
The utility model content
The utility model provides a kind of rotovator simple in structure, easy to use, and reaching does not need stalk and weeds chopping, the straw application rotary cultivator that yet can carry out rotary tillage.
The utility model adopts following technical scheme:
A kind of straw winding straw application rotary cultivator, comprise housing and the gear-box, power transmission box, support arm, cutter shaft and the some rotary blades that set firmly on it, rotary blade by bolt on cutter shaft, wherein, described rotary blade is made up of vertical colter and horizontal colter, the root of described vertical colter is vertically located on the cutter shaft, and the two ends of described horizontal colter are fixedly arranged on the two adjacent vertical colters, and its connecting portion is close to the tail end of vertical colter.
Further, for reaching preferable straw winding effect, described horizontal colter is elongated, and its fixed-direction and its direction of rotation form an acute angle.
Further, the preferable angular range of this acute angle is: 1～30.
Further, for reaching preferable rotary tillage purpose, described horizontal colter inboard is provided with the hack blade.
Further, for avoiding stalk and weeds to twine in the joint portion of cutter shaft and support arm and power transmission box, near the vertical colter of support arm and power transmission box, its set bolt stretches out and forms a retaining straw articles, and this retaining straw articles is overlying on the joint portion of cutter shaft and support arm and power transmission box.
By above-mentioned description to the utility model structure as can be known, compare, be provided with the horizontal colter of strip between the vertical colter of the present utility model with prior art, not only can improve the intensity of cutter, increase the service life, and stalk and weeds can be pressed in the soil, avoid it to twine on cutter shaft.Also be provided with the retaining straw articles on the joint portion of cutter shaft and support arm and power transmission box simultaneously, avoid stalk and weeds to enter the position, gap of axle head, thereby play the effect of protection machine.This rotovator is simple in structure, and original rotovator only need carry out the purpose that simple refit can reach straw-returning and straw winding, is useful in very much vast rural area and applies.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is a colter structural representation of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below with reference to Fig. 1, Fig. 2.
With the dongfeng-12 rotovator is that prototype improves, rotovator of the present utility model is made up of housing (not shown) and the gear-box 1, power transmission box 2, support arm 3, cutter shaft 4, vertical colter 5 and the horizontal colter 6 that set firmly on it, the root of vertical colter 5 is vertically located on the cutter shaft 4, the two ends of horizontal colter 6 are fixedly arranged on the tail end of two adjacent vertical colters 5, and end is reserved about 15mm.Horizontal colter is elongated, and its fixed-direction (direction shown in the dotted line among Fig. 2) is 10 ° with its direction of rotation (direction shown in the arrow among Fig. 2) angle, has so both had good hack ability, do not increase the load of power, and straw can be pressed in the soil, do not trigger, make the plot after ploughing more smooth.For further improving the hack ability, be welded with two hack blades 8 in the inboard of horizontal colter 6, this hack blade 8 is triangular in shape.
Change 18 colter seats on original cutter shaft 4 into 12, per 2 is one group, totally 6 groups, on cutter shaft 4, distribute one group by axial branch trisection, radially per 60 degree, form vertically three groups (working width) radially relative 180 degree respectively distribute two groups totally six groups of 12 colter seats fix vertical colter 5.Three groups of colter groups that distribute adjacent in the working width vertically need to overlap mutually, just are unlikely to balk.Every group of colter group specification is identical, can assemble arbitrarily and change.
The vertical colter in original rotovator outside, its set bolt all adopts the mounting means of ecto-entad, the end of bolt stretches to rotovator inside, for avoiding stalk and weeds to twine in the joint portion of cutter shaft and support arm and power transmission box, the utility model adopts the set bolt 7 of lengthening, be used for fixing vertical colter 5 near support arm and power transmission box, and the mounting means that set bolt 7 adopts from inside to outside, the elongated portion of this set bolt 7 is carried out on the joint portion of cutter shaft and support arm and power transmission box, form a retaining straw articles, can effectively stop stalk and weeds to be involved in the joint portion of cutter shaft and support arm and power transmission box.Because the set bolt 7 of this lengthening weares and teares easily, need to make with the hard steel.
Above-mentioned is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection domain.
