Abstract
The invention discloses a rotary blade for soft soil. The rotary blade comprises an installing cylinder, wherein an outer-layer cylinder is further arranged outside the installing cylinder, and a plurality of rotary blades are arranged on the outer wall of the outer-layer cylinder in a radial manner. The roots of the rotary blades are welded with a blade base, and the blade base is connected with the outer-layer cylinder through bolts. According to the rotary blade for soft soil, the depth of rotary plough can be limited through the outer-layer cylinder, so that the rotary blade is particularly applicable to paddy field working; through the adoption of the connection mode of the blade base, the rotary blade is convenient to detach and replace, and is beneficial for rotationally ploughing and flattening soft soil with oppositely arranged bent rotary blades. An extra crawling power can be provided by the bent part at the free end of the rotary blade. Due to the rotary blades which are oppositely arranged in pairs, the axial component force along the outer-layer cylinder is reduced, and thus the control is facilitated.
Description
Technical field
The present invention relates to the rotary blade in a kind of farm machinery, especially a kind of rotary blade for soft earth.
Background technology
In existing rotovator, the structure of rotary blade is that sleeve is provided with blade, for by soil scarifying.But for comparatively soft earth, existing rotary blade is easily trapped in earth, is unfavorable for advancing, and existing rotary blade is difficult to guarantee that the rotary tillage of soft earth is smooth.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of rotary blade for soft earth, can limit the degree of depth of rotary tillage, further, can guarantee that rotary tillage is smooth.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of rotary blade for soft earth, comprise installation cylindrical shell, and to install outside cylindrical shell and be also provided with outer layer barrel, a plurality of Rotary tillage blades are radial arrangement at the outer wall of outer layer barrel.
Root and the blade base of described Rotary tillage blade are welded to connect, and blade base and outer layer barrel are bolted.
On described blade base, be provided with in opposite directions two Rotary tillage blades.
The free end of two described Rotary tillage blades is bending laterally all.
A kind of rotary blade for soft earth provided by the invention, by the outer layer barrel arranging, can limit the degree of depth of rotary tillage, be particularly useful for paddy-field-working, adopt the connected mode of blade base, be convenient to dismounting and change, the Rotary tillage blade of the bending being oppositely arranged, is conducive to the rotary tillage of soft earth smooth.The free-ended bending part of Rotary tillage blade can also provide the extra power of creeping.The Rotary tillage blade being oppositely arranged is between two conducive to reduce the axial thrust load along outer layer barrel, thereby be beneficial to, controls.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the integrally-built schematic side view of the present invention.
Fig. 2 is that master of the present invention looks schematic diagram.
In figure: Rotary tillage blade 1, blade base 2, outer layer barrel 3, installs cylindrical shell 4, mounting screw 5, fabrication hole 6.
Embodiment
In Fig. 1,2, a kind of rotary blade for soft earth, comprise cylindrical shell 4 is installed, install outside cylindrical shell 4 and be also provided with outer layer barrel 3, outer layer barrel 3 is connected by connecting plate or reinforcement with installing between cylindrical shell 4, because outer layer barrel 3 is larger, make it be unfavorable for sinking in earth, thereby for limiting the rotary tillage degree of depth.A plurality of Rotary tillage blades 1 are radial arrangement at the outer wall of outer layer barrel 3.
In Fig. 1,2, root and the blade base 2 of described Rotary tillage blade 1 are welded to connect, and blade base 2 is bolted with outer layer barrel 3.Structure, is convenient to dismounting and change thus.
On described blade base 2, be provided with in opposite directions two Rotary tillage blades 1.Structure, is conducive to the rotary tillage of soft earth smooth thus.And the Rotary tillage blade being oppositely arranged is between two conducive to reduce the axial thrust load along outer layer barrel, thereby be beneficial to, controls.
The free end of two described Rotary tillage blades 1 is bending laterally all.Structure thus, the free-ended bending part of Rotary tillage blade can also provide the extra power of creeping.
Claims (4)
1. for a rotary blade for soft earth, comprise cylindrical shell (4) is installed, it is characterized in that: install outside cylindrical shell (4) and be also provided with outer layer barrel (3), a plurality of Rotary tillage blades (1) are radial arrangement at the outer wall of outer layer barrel (3).
2. a kind of rotary blade for soft earth according to claim 1, is characterized in that: the root of described Rotary tillage blade (1) and blade base (2) are welded to connect, and blade base (2) is bolted with outer layer barrel (3).
3. a kind of rotary blade for soft earth according to claim 2, is characterized in that: on described blade base (2), be provided with in opposite directions two Rotary tillage blades (1).
4. a kind of rotary blade for soft earth according to claim 2, is characterized in that: the free end of described two Rotary tillage blades (1) is bending laterally all.
