Abstract
The utility model relates to a rotary blade with replaceable blades, which comprises a shaft sleeve, wherein a plurality of blade seats are arranged on the shaft sleeve in a radial manner; rotary tillage blades are connected with the blade seats; and the rotary tillage blades are connected with the blade seats through bolts or bayonets. The rotary blade with the replaceable blades, provided by the utility model, has the advantages that the rotary tillage blades can be replaced after abrasion, so as to reduce entirety usage cost; according to softness and hardness of soil, different numbers of rotary tillage blades can be adopted, for example, only three to four rotary tillage blades are arranged for the softer soil, while five to six rotary tillage blades are adopted for the harder soil; and auxiliary blades arranged enable the whole rotary tillage blades to be wider, are used for scarifying the soil, and can push the soil from the two sides to the middle for hilling after ditching.
Description
Technical field
The utility model relates to the rotary blade in a kind of farm machinery, especially a kind of more allowing blade replacement rotary blade.
Background technology
In existing rotovator, the structure of rotary blade is that sleeve is provided with blade, is used for the soil scarifying.But need integral replacing after the wearing and tearing of existing rotary blade, use cost is higher, and is difficult to switch according to ground condition the quantity of blade for the soil of different soft and hard degree, and existing rotary blade only is mainly used in loosening the soil, and is difficult to use in ridging.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rotary blade of changeable blade, can be according to operating mode blade abrasion situation for example, or switch the quantity of blade according to the soft or hard degree of earth; Further, can also be used for ridging.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of rotary blade of changeable blade, comprise axle sleeve, and become radial a plurality of blade bearings that are provided with on axle sleeve, Rotary tillage blade is connected with blade bearing.
Described Rotary tillage blade is connected by bolt or bayonet socket mode with blade bearing.
Described a plurality of blade bearing is positioned at the two ends of axle sleeve.
The free-ended side of described Rotary tillage blade also is provided with auxiliary blade.
The pitch of described auxiliary blade is greater than the pitch of Rotary tillage blade.
The rotary blade of a kind of changeable blade that the utility model provides, can when wearing and tearing, Rotary tillage blade change, reduced whole use cost, for the different situation of earth soft or hard degree, can adopt the Rotary tillage blade of varying number, for example for comparatively soft earth, 3-4 Rotary tillage blade can only be set, and can adopt 5-6 Rotary tillage blade for harder earth.The auxiliary blade that arranges makes whole Rotary tillage blade wider, except can be used for loosening the soil, and in the middle of earth can also being pushed to from both sides, thus the ridging after can be used for ditching.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the integrally-built schematic side view of the utility model.
Fig. 2 is that master of the present utility model looks schematic diagram.
In figure: Rotary tillage blade 1, auxiliary blade 2, fastening bolt 3, blade bearing 4, axle sleeve 5, mounting screw 6.
Embodiment
In Fig. 1, Fig. 2, a kind of rotary blade of changeable blade comprises axle sleeve 5, becomes radial a plurality of blade bearings 4 that are provided with on axle sleeve 5, and Rotary tillage blade 1 is connected with blade bearing 4.Adopted 5 blade bearings in this example, but for the comparatively soft operating mode of earth, 3-4 Rotary tillage blade can only be installed.
In Fig. 1,2, described Rotary tillage blade 1 is connected by bolt or bayonet socket mode with blade bearing 4.Adopt the mode of fastening bolt 3 to connect in this example, but for ease of quick-detachment, it is also feasible adopting the bayonet socket mode to connect, and for example adopts the wedge shape bayonet socket with the mode of Rotary tillage blade wedging, adopts the device of similar ratchet that Rotary tillage blade is locked, not shown.
As shown in Figure 2, described a plurality of blade bearing 4 is positioned at the two ends of axle sleeve 5.
In Fig. 1, the free-ended side of described Rotary tillage blade 1 also is provided with auxiliary blade 2.The auxiliary blade that arranges broadens the width of whole Rotary tillage blade, thereby except the effect of loosening the soil, the effect that also has soil-shifting, for example on the axle that is arranged on engine that the utility model is paired, coordinate trenching cutter, in the middle of can being used for the earth of both sides is pushed to, thereby after trench digging, realize covering the function of soil.
The pitch of described auxiliary blade 2 is greater than the pitch of Rotary tillage blade 1.Structure thus, the inclination angle that auxiliary blade 2 is larger.Further optimized the effect of bulldozing.
Claims (5)
