Abstract
The utility model provides a rotary blade of a minitiller, which comprises a rotary shaft, a blade rest and a blade, wherein the blade rest is arranged on the rotary shaft; the blade is matched with the blade rest; and the bending angle of the blade is 155-162 degrees. For the rotary blade of the minitiller, by changing the bending angle of the blade of the rotary blade, the earth-in angle of the blade can achieve an optimum state, so that the resistance borne by the blade becomes smaller as the bending angle of the blade changes in the following whole earth-cutting process, thereby improving the operating stability of the minitiller and reducing the wear rate of the blade of the rotary blade.
Description
Technical field
The utility model relates to the mini-size tillage machine field, relates in particular to a kind of rotary blade of mini-size tillage machine.
Background technology
The mini-size tillage machine build is small and exquisite, and acquisition expenses is low, in agricultural production, obtains increasing application in recent years.The main working parts of mini-size tillage machine is a rotary blade; Its through the rotation and forward travel directly to farmland rotary tillage operation, the concrete course of work comprises rotary blade rotation, the cutting of burying, throwing soil and advances, when rotary blade acts on soil; Soil equally also reacts on the rotary blade blade; Be mingled with under the situation of hard things such as masonry in the higher or soil at soil hardness, the suffered resistance of rotary blade blade is bigger, and the position of rotary blade blade blade in the process of rotary tillage soil constantly changes; Select suitable blade angle of penetration to help to reduce the suffered resistance of blade, the stability when helping the mini-size tillage machine operation.
The utility model content
The utility model technical problem to be solved has provided a kind of mini-size tillage machine rotary blade, to solve the bigger problem of the suffered resistance of rotary blade blade.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is: a kind of mini-size tillage machine rotary blade is provided, and the blade that comprises rotating shaft, is arranged on the knife rest in the rotating shaft and matees with said knife rest, the bending angle of said blade is 155 °~162 °.
Further, said knife rest and said rotating shaft welding.
Further, said knife rest is connected through bolt with said blade.
Further, the quantity with the blade of said knife rest coupling is 3.
Further, the quantity of said knife rest is 6~8.
The beneficial effect of the utility model is: through changing the bending angle of rotary blade blade; Make the angle of penetration of blade reach an optimum state; Make blade after the process of whole cutting soil in; Since the resistance force diminishes that the variation of blade bending angle receives blade, thus the stability when mini-size tillage machine moves improved, also reduced the wear rate of rotary blade blade simultaneously.
Description of drawings
Fig. 1 is the structural representation of the mini-size tillage machine rotary blade that provides of the utility model embodiment;
Fig. 2 is the front projection structural representation of the mini-size tillage machine rotary blade that provides of the utility model embodiment.
Shown in the figure: 11, rotating shaft, 12, knife rest, 13, blade.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the mini-size tillage machine rotary blade that the utility model proposes is done further explain.According to following explanation and claims, advantage of the utility model and characteristic will be clearer.What need explanation is, accompanying drawing all adopts the form of simplifying very much and all uses non-ratio accurately, only is used for conveniently, the purpose of aid illustration the utility model embodiment lucidly.
The core concept of the utility model is; A kind of mini-size tillage machine rotary blade is provided,, makes the angle of penetration of blade reach an optimum state through changing the bending angle of rotary blade blade; Make blade after the process of whole cutting soil in; Since the resistance force diminishes that the variation of blade bending angle receives blade, thus the stability when mini-size tillage machine moves improved, also reduced the wear rate of rotary blade blade simultaneously.
As shown in Figure 1, the utility model provides a kind of mini-size tillage machine rotary blade, the blade 13 that comprises rotating shaft 11, is arranged on the knife rest 12 in the rotating shaft 11 and matees with said knife rest 12, and the bending angle of said blade 13 is 155 °~162 °.
Particularly, said knife rest 12 and said rotating shaft 11 welding, said knife rest 12 and said blade 13 are connected through bolt, and the quantity of the blade 13 that matees with said knife rest 12 is 3, and the quantity of said knife rest is 6~8.In the present embodiment, the quantity of said knife rest is 8, and wherein 4 blades 13 on one side of mini-size tillage machine only are shown in Fig. 1.
Fig. 2 is the front projection structural representation of the mini-size tillage machine rotary blade that provides of the utility model embodiment.With reference to Fig. 2, when the mini-size tillage machine operation that utilizes the utility model to provide, because the bending angle of said blade 13 is 155 °~162 °; In the present embodiment; The bending angle of said blade 13 is 162 °, and is littler than the bending angle of general blade, thereby makes blade 13 that a preferable penetrating angle arranged before burying; And when blade 13 buries cutting and blade 13 rotations; The resistance force diminishes that blade 13 receives, thus the stability when mini-size tillage machine moves improved greatly, also reduced the wear rate of rotary blade blade simultaneously.
Obviously, those skilled in the art can carry out various changes and modification to utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
Claims (5)
