Abstract
The utility model relates to a knife flywheel structure of a scarifier. The knife flywheel structure of the scarifier comprises a knife flywheel shaft and a plurality of groups of blades installed on the knife flywheel shaft, wherein one end of the knife flywheel shaft is in connection with an output end of power equipment. The knife flywheel structure of the scarifier is characterized in that each blade is a single-tooth blade, the blades are installed on the knife flywheel shaft through blade limiting sleeves in a way that each two of the blades are in one group and diagonally arranged, and the blades are assembled in a spiral way of rotating in a certain angle when a group of the blades are installed. According to the knife flywheel structure of the scarifier, double-tooth blades of a traditional knife flywheel are changed into the single-tooth blades, and the blades are assembled in the way that two of the blades are in one group and in the spiral way of rotating 60 degrees when one group of the blades are installed, and therefore the blades are greatly shortened, material cost is saved, and a balancing problem of a single knife is solved. Therefore, a double-knife effect of a single-knife structure can be achieved, cost is greatly reduced, meanwhile, operation is convenient, and vibration is lightened.
Description
Technical field
The utility model belongs to the garden instrument technical field, specifically the cutting wheel structure of a kind of lawn loosenning tiller.
Background technology
Along with growth in the living standard, the greening level that people live to life requires more and more higher, large-scale ecological greenery patches, city, dwelling house greenery patches, Road Green Space etc. constantly increase, therefore various garden instruments are also constantly released, wherein the lawn loosenning tiller is because of lightweight, the advantages such as volume is little, flexible operation, and is subject to liking of user.Loosenning tiller is mainly used in the small size deep ploughing, shallow plowing, plough, whole ground, hoe up weeds, the usefulness of cultivation, during work mainly the rotation by the break bar that loosens the soil reach the purpose of loosening the soil, but the blade of the present break bar that loosens the soil (such as Fig. 3 b) be generally bidentate blade 2 ', installing hole by the blade middle part is installed on the break bar axle, although bidentate blade 2 ' the constitutional balance performance fine, but in use, because set of blades is in rotation at a high speed, the bidentate blade 2 ' relative manipulating object that rotates a circle has formed and has repeated cutting, half that has more just plays the effect of balance, therefore relatively waste exists blade long, the defective that material cost is high.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cutting wheel structure of simple and reasonable loosenning tiller, and its blade adopts the structure of monodentate blade, and balance quality is good when not only working, and reduces vibration, and cost is economized, saved to material.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of cutting wheel structure of loosenning tiller, comprise break bar axle and some groups of blades that are installed on the break bar axle, one end of break bar axle links to each other with the output of power-equipment, it is characterized in that described blade is the monodentate blade, be installed on the break bar axle by the blade stop collar take two as one group of mode that is the diagonal angle setting respectively, and fill one group of blade and assemble with the spiral way that rotates to an angle with every.
As improvement, described blade is to fill one group of blade and assemble with the spiral way of rotating 60 ° with every.
As improvement, described break bar axle adopts six square shafts as the stamen axle, and the middle part of described blade stop collar and the afterbody of blade are equipped with corresponding hexagonal hole, and described blade stop collar and the blade respectively hexagonal hole by separately are the interval and fixedly are nested with on the break bar axle.
Improve, an end of described break bar axle links to each other with the output of power-equipment by the power transmission nut again.
At last, the two ends of described break bar axle are arranged with respectively a dust cover, between the inboard of dust cover and blade, be lined with special-shaped pad, on the axle head of the break bar axle in the dust cover outside on the left of the power transmission nut is installed in, bearing is installed on the axle head of break bar axle in the dust cover outside on right side, also be provided with a hex nut between the dust cover on bearing and right side, be lined with pad between the dust cover on described hex nut and right side, the outside of described bearing is fixed with an axle split washer.
Compared with prior art, the utility model has the advantage of: change traditional bidentate blade into the monodentate blade, and fill one group of blade and be 60 ° spiral way of rotation and assemble with every take two blades as one group, this is not only so that blade shortens dramatically, saved material cost, and the set of blades of arranging in the shape of a spiral can be improved the ride comfort to the soil cutting, can effectively reduce the impact when soil cut, the requirement for dynamic balance in the time of can making break bar reach work reduces vibration.The utility model is simple in structure, by rational arrangement assembly, has solved the equilibrium problem of hilted broadsword, thereby makes the hilted broadsword structure reach the effect of double-pole so that cost greatly reduces, simultaneously more convenient operation, reduced vibration.

Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of cutting wheel structure of loosenning tiller, comprise break bar axle 1 and the some groups of blades 2 that are installed on the break bar axle 1, one end of break bar axle 1 links to each other with the output of power-equipment by power transmission nut 6, the other end is equipped with bearing 5, break bar axle 1 adopts six square shafts as the stamen axle, blade 2 is the monodentate blade, the afterbody of blade 2 is provided with the hexagonal hole 2a corresponding with six square shafts of break bar axle 1, blade 2 is installed on the break bar axle 1 by blade stop collar 3 take two as one group of mode that is the diagonal angle setting respectively, the middle part of blade stop collar 3 is provided with corresponding hexagonal hole 3a, blade stop collar 3 and blade 2 respectively the hexagonal hole 3a by separately and 2a are the interval and fixedly are nested with on break bar axle 1, and every group of adjacent blade assembles with the spiral way of rotating 60 °;
The two ends of break bar axle 1 are arranged with respectively dust cover 4a and a 4b, between the inboard of dust cover 4a and 4b and blade 2, be lined with different in nature pad 7, on the axle head of the break bar axle 1 in the dust cover 4b outside on the left of power transmission nut 6 is installed in, bearing 5 is installed on the axle head of break bar axle 1 in the dust cover 4a outside on right side, between the dust cover 4a on bearing 5 and right side, also be provided with a hex nut 8, be lined with pad 10 between the dust cover 4a on hex nut 8 and right side, also be fixed with axle split washer 9 in the outside of bearing 5.
