Abstract
A rotary blade is composed of a blade shaft (1), blade holders (2), left bent blade bodies (3) and right bent blade bodies (4). The rotary blade is characterized in that the blade shaft (1) is a cylindrical body with one end provided with a screw hole, the blade holders (2) are square tubular bodies, each left bent blade body (3) is a strip-shaped body with one end bent towards the left rear, and each right bent blade body (4) is a strip-shaped body with one end bent towards the right rear; every two blade holders (2) constitute a set, the included angel between every set of blade holders (2) is 180 degrees, and each set of blade holders (2) are welded to the outer surface of the blade shaft (1) in a radial shape; the left bent blade bodies (3) and the right bent blade bodies (4) are fixed to the blade holders (2) through bolts (5), one left bent blade body (3) and one right bent blade body (4) are fixed to the set of blade holders (2) closest to the end, provided with the screw hole, of the blade shaft (1) respectively, the right bent blade bodies (4) are fixed to the blade holders (2) away from the end, provided with the screw hole, of the blade shaft (1) within one third of the length of the total blade shaft (1), the left bent blade bodies (3) are fixed to the other blade holders (2), the left bent blade bodies (3) and the right bent blade bodies (4) are bent in the same direction when seen from the axial direction. The rotary blade has the advantages of being high in stubble cleaning efficiency, high in soil loosening capacity and good in ridging effect.
Description
Technical field
The utility model relates to a kind of agro-farming component of machine, particularly a kind of rotary blade.
Background technology
Rotovator is mainly used blade cut, breaks up the clods, and loose puddles topsoil, uses existing rotary blade because of its tool rest and cutter hub arrangement mode imperfection, and reasonable structure is poor, exists stubble-cleaning efficiency low, the shortcoming of the weak and ridging weak effect of the ability of loosening the soil.
Utility model content
The purpose of this utility model is: provide a kind of stubble-cleaning efficiency high, the strong and effective rotary blade of ridging of the ability of loosening the soil.
Technical solution of the present utility model is: it is by cutter shaft, tool rest, left tulwar body and right tulwar body form, it is characterized in that cutter shaft is the cylinder-like body of one end band screw, tool rest is square tube type body, left tulwar body is a rear crooked bar shape left, right tulwar body is a rear crooked bar shape to the right, two tool rests are one group, angle before every group of tool rest is 180 degree, every group of tool rest is radial and is welded on cutter shaft outer surface, left tulwar body and right tulwar body are bolted on tool rest, with fixing respectively left tulwar body and right tulwar body on first group of tool rest of cutter shaft one end of screw, from the cutter shaft one end with screw, account for the fixing right tulwar body on the tool rest in total cutter shaft 1/3rd, on all the other tool rests, fix left tulwar body, axially see that left tulwar body and right tulwar body are equidirectional bending.
Technique effect of the present utility model is: it is high that it has stubble-cleaning efficiency, the strong and effective advantage of ridging of the ability of loosening the soil.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment faces structure chart.
Fig. 2 is the utility model embodiment side-looking structure chart.
Embodiment
As shown in Figure 1: it is by cutter shaft 1, tool rest 2, left tulwar body 3 and right tulwar body 4 form, it is characterized in that cutter shaft 1 is for the cylinder-like body of one end band screw, tool rest 2 is square tubular body, left tulwar body 3 is a rear crooked bar shape left, right back tulwar body 4 is a bar shape for bending to the right, two tool rests 2 are one group, angle before every group of tool rest 2 is 180 degree, every group of tool rest 2 is radial and is welded on cutter shaft 1 outer surface, left tulwar body 3 and right tulwar body 4 are fixed on tool rest 2 by bolt 5, from fixing respectively left tulwar body 3 and right tulwar body 4 on one group of nearest tool rest 2 of cutter shaft 1 one end with screw, from cutter shaft 1 one end with screw, account for the fixing right tulwar body 4 on the tool rest 2 in total cutter shaft 1/1st three, on all the other tool rests 2, fix left tulwar body 3, axially see that left tulwar body 3 and right tulwar body 4 are equidirectional bending.
