Description
Technical field
The utility model relates to a kind of knife roller device for stubble-cleaning and rotary tillage, belongs to agricultural machinery technological field.
Background technology
In current tillage method, a new round sowing before, cultivated whole process be carried out, more carry out have broken stubble and rotary tillage, for these two kinds of ploughing operations, had stubble cutter, rotovator.
The rotor of existing rotovator is made up of tool roller axis, tool rest, rotary blade, and the tool rest with a hole is vertically welded on cutter shaft, and rotary blade inserts in tool rest and also fixes with a screw bolt and nut.Each surface of revolution only has two cuttves, the bite length revolution of rotary blade ensures, under identical axle rotational speed, if want to reduce bite length, then need to increase cutter number, but this tool rest installs the form of rotary blade, when the tool rest quantity of a surface of revolution is more than two, folder soil can be produced, twine the phenomenon of grass, bring adverse influence to rotary tillage.Broken stubble operation operates mainly in Tai Gencha district, ridge, is different from the full width rotary tillage of rotary tillage process, and also the rotary tillage degree of depth is shallow relatively for the broken stubble degree of depth, broken stubble bite length requires less, except improving axle rotational speed, also can increase knife number, meeting the requirement of broken stubble operation.
The design philosophy that 3 kinds new is had at present: the first adopts twin shaft to carry out stubble ploughing, rotary tillage operation simultaneously in rotary tillage-broken stubble operation is general.The second adopts cutter shaft, general cutterhead, changes blade structure.The third adopts cutter shaft, cutterhead, interchangeable blade structure.In the first structure, the complex structure of machine, complex operation, cost is high, the supporting power waste energy.The cutterhead of general cutter rod adopts universal architecture, namely on cutterhead, there is the installing hole that two kinds dissimilar, Rotary tillage blade and stubble smashing blade can be installed respectively, often kind of blade meets and arranges requirement separately, Rotary tillage blade and stubble smashing blade can be installed respectively, often kind of blade meets and arranges requirement separately, can meet the requirement of rotary tillage or broken stubble operation by more allowing blade replacement; In the second structure, universl cutting roller still adopts cutter head structure, and unlike employing interchangeable blade, blade meets the requirement of multi-head spiral line arrangement on rotor, realizes rotary tillage-broken stubble general by the rotating speed changing rotor.The first structure relatively other structures makes great progress, but it still could will realize general by more allowing blade replacement, and therefore production efficiency is relatively not high, can't truly general at last.The second structure adopts interchangeable blade, as long as the rotating speed changing rotor just can realize general, but less between its farmland types variable region, also have much room for improvement.From present case, also there is no to realize rotary tillage, stubble-cleaning is general, the rotor of cutterhead spacing and knife number can be regulated again simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of knife roller device for stubble-cleaning and rotary tillage that can overcome above-mentioned defect, can need to change at any time according to difference cutterhead spacing, excellent working performance.Its technical scheme is:
A kind of knife roller device for stubble-cleaning and rotary tillage, comprise cutter shaft and be arranged on many groups of whole ground unit on cutter shaft, often organize whole ground unit to include cutterhead and be arranged on the multiple blades on cutterhead, it is characterized in that: cutterhead is gear-like, quantity is circumferentially evenly equipped with identical at two concentrics of cutterhead different-diameter, and with the bolt holddown groove of circumference with radian, multiple blade is distributed on cutterhead, each blade is all fixedly mounted on through bolt and is positioned on the bolt holddown groove of two circumference, blade is provided with towards the sidewall of cutterhead the teeth groove matched with the tooth on cutterhead, the center of circle of 2 bolts of fixing same blade was positioned on the same ray in the cutterhead center of circle with the crown of the tooth be stuck in teeth groove, cutter shaft is provided with many grooves vertically, and the distance between adjacent grooves is equal, and the cutterhead often organizing whole ground unit is all sleeved on cutter shaft, and fixes through screw.
The described knife roller device for stubble-cleaning and rotary tillage, cutter shaft is provided with 2-8 group whole ground unit, each cutterhead is evenly equipped with 3-6 blade.
Compared with prior art, its advantage is the utility model:
1, by regulating the mode of cutterhead cutter quantity and blade kind, the switching between rotary tillage and broken stubble operation can be realized;
The quantity of cutter shaft upper tool pan can be regulated, to adapt to the requirement of different agronomy.
2, dismantle easy to assembly, reasonable stress, fast reliably, a tractor serves several purposes, the efficiency that comes into force is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the general cutterhead installation three of the utility model assembles schematic diagram cutter;
Fig. 3 is the partial enlarged drawing of middle part A embodiment illustrated in fig. 2;
Fig. 4 is that the general cutterhead installation four of the utility model assembles schematic diagram cutter.
In figure: 1, cutter shaft 2, cutterhead 3, blade 4, bolt holddown groove 5, bolt 6, teeth groove 7, tooth 8, groove 9, screw 10, locating hole
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.In the embodiment shown in Fig. 1-3: cutter shaft 1 is provided with vertically 4 grooves 8, the distance between adjacent grooves 8 is equal, two cutterheads 2 are all sleeved on cutter shaft 1, and are fixed on groove 8 through locating hole 10 with screw 9.2 cutterheads 2 are all in gear-like, two concentrics of cutterhead 2 different-diameter be circumferentially evenly equipped with 3 with the bolt holddown groove 4 of circumference with radian, 3 blades 3 are distributed on cutterhead 2, each blade 3 is all fixedly mounted on through bolt 5 and is positioned on the bolt holddown groove 4 of two circumference, blade 3 is provided with towards the sidewall of cutterhead 2 teeth groove 6 matched with the tooth 7 on cutterhead 2, and the center of circle of 2 bolts 5 of fixing same blade 3 was positioned on the same ray in cutterhead 2 center of circle with the crown of the tooth 7 be stuck in teeth groove 6.
Substantially the embodiment shown in same Fig. 2-3 embodiment illustrated in fig. 4, just uniform 4 blades on each cutterhead 2.
