Abstract
The invention discloses a rotary cultivator rotating knife, which relates to the technical field of agricultural machinery manufacturing, and comprises a long knife body, wherein the knife body is bent to be an arc shape toward the thickness direction, a cutting edge portion is arranged on a bent outer radian position of the knife body, the cutting edge angle of the cutting edge portion is in 10 degrees-18 degrees, two pressing blades which are used to poke and press large soil particles and are bent to be an arc shape are symmetrically arranged on the two sides of the tail end of the knife body, and the pressing blades are bent toward the direction of the cutting edge portion of the knife body. Compared with the prior art, the rotary cultivator rotating knife can solve the problems that existing rotary cultivator rotating knives are not reasonable in structure and not enough in plough depth.
Description
Technical field
The present invention relates to manufacture of agricultural machinery technical field, especially a kind of rotary shaft rotovator revolves and rotor revolves cutter.
Background technology
What existing rotary shaft rotovator revolves rotor revolves cutter, generally comprises microscler cutter hub, and cutter hub bends curved towards thickness direction, and the end revolving cutter is formed for dialling the pressure leaf portion pressing large grogs to curving.When the rotating shaft of revolving rotor rotates, revolve blade row to revolve cutter radial rolling, the soil in field is pushed aside by the pressure leaf portion of revolving cutter, is crushed by large grogs simultaneously, soil is ploughed ploughs carefully more broken, but because the structure revolving cutter makes to revolve cutter, to enter the degree of depth of soil limited, although be conducive to hack, the degree of depth of ploughing plough is inadequate, generally need to use the rotovator of vertical shaft type to carry out ploughing plough, want to obtain comparatively ideal arable land situation, need to plough plough twice, extremely bother.
Summary of the invention
Problem to be solved by this invention is to provide a kind of rotovator and revolves cutter, and to solve existing rotovator, to revolve knife structure unreasonable, ploughs the problem that the degree of depth of plough is inadequate.
In order to solve the problem, technical scheme of the present invention is: this rotovator revolves cutter and comprises microscler cutter hub, described cutter hub bends curved towards thickness direction, the outer radian position that described cutter hub is bending has cutting edge portion, the blade angle in described cutter hub cutting edge portion is within the scope of 10 ° ~ 18 °, the end bilateral symmetry of described cutter hub is provided with the curved pressure leaf for dialling the large grogs of pressure of two bending tablets, and described pressure leaf bends to the direction, cutting edge portion of described cutter hub.
In technique scheme, more specifically technical scheme can be: described cutter hub root is provided with protruding installation bolt.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The cutting edge that this rotovator revolves cutter is opened and is being revolved the bending outer radian position of cutter, the cutting of cutter along the radial direction of rotating shaft is revolved to increase, the i.e. cutting in vertical direction soil depth direction, the end bilateral symmetry of cutter hub is provided with the curved pressure leaf for dialling the large grogs of pressure of two bending tablets, both the large grain grogs stirring and provoke pressure group and dig can have been played when cutter hub vertical direction is cut, the holding power of vertical direction can be increased again, impose the intensity of vertical direction cutting.This rotovator revolves cutter has taken into account broken thin two functions larger with ploughing the plough degree of depth of cultivated plough soil simultaneously, easy to use, is suitable for the cultivated plough in various soil field.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the left view of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
This rotovator as shown in Figure 1 and Figure 2 revolves cutter, it comprises microscler cutter hub 1, cutter hub 1 bends curved towards thickness direction, the outer radian position that cutter hub 1 is bending has cutting edge portion 1-1, the blade angle A=10 ° in the cutting edge portion of cutter hub 2, revolves the cutting of cutter along the radial direction of rotating shaft to increase, the i.e. cutting in vertical direction soil depth direction, the scope that angle is 10 ° to 18 °, namely ensure that the sharpness of cutting, in turn ensure that the intensity of cutting.The end bilateral symmetry of cutter hub 1 is provided with the curved pressure leaf 2 for dialling the large grogs of pressure of two bending tablets, pressure leaf 2 bends to the 1-1 direction, cutting edge portion of cutter hub 1, both the large grain grogs stirring and provoke pressure group and dig can have been played when revolving the cutting of cutter 2 vertical direction, the holding power of vertical direction can be increased again, impose the intensity of vertical direction cutting.Cutter hub 1 root is provided with protruding installation bolt 1-2.This rotovator revolves cutter has taken into account broken thin two functions larger with ploughing the plough degree of depth of cultivated plough soil simultaneously, easy to use, is suitable for the cultivated plough in various soil field.
In other embodiments, the angle A of revolving the cutting edge of cutter 2 can select any one numerical value between 10 ° to 18 °.
Claims (2)
1. a rotovator revolves cutter, comprise microscler cutter hub, described cutter hub bends curved towards thickness direction, it is characterized in that: the outer radian position that described cutter hub is bending has cutting edge portion, the blade angle in described cutter hub cutting edge portion is within the scope of 10 ° ~ 18 °, the end bilateral symmetry of described cutter hub is provided with the curved pressure leaf for dialling the large grogs of pressure of two bending tablets, and described pressure leaf bends to the direction, cutting edge portion of described cutter hub.
2. rotovator according to claim 2 revolves cutter, it is characterized in that: described cutter hub root is provided with protruding installation bolt.
