Abstract
The utility model relates to a rotary blade including a blade handle, a blade body, and a blade head, the blade body includes a blade back and a blade edge, and the blade back and a blade edge are arc-shaped. Because the blade body includes the blade back and the blade edge, the strength of the blade body is greatly improved, and the blade body is not easy to damage during the use and is longer in service life. When the blade is used for cultivation, the cultivation depth is 50% deepened compared with that of a conventional cutter, the blade back and the blade edge are arc-shaped, the roots of crops are not easy to wind on the blade body, thereby greatly improving the work efficiency.
Description
Technical field
The utility model relates to a kind of garden supervisor parts, relates to specifically a kind of rotary blade.
Background technology
Garden supervisor has lightweight, and the features such as oil consumption is low, relative power is large, compact conformation, mobility strong, manipulation light and flexible can be climbed, more the ridge, ladder are strong, is widely used in the work such as cultivated whole, management on booth, orchard, vegetable plot, cigarette ground.
The rotary blade now using is mostly sheet or tabular, in rotary tillage process, rotary blade is stressed larger, and sheet or tabular rotary blade intensity are low, fragile, service life is short, in use, the tilling depth of rotary blade is more shallow, is easily wound around the rhizome of crops on rotary blade, need to regularly clear up, affect operating efficiency.
Utility model content
Problem to be solved in the utility model is for above problem, and the rotary blade that a kind of intensity is high, not fragile, tilling depth is dark, operating efficiency is high is provided.
For addressing the above problem, the technical scheme that the utility model adopts is: a kind of rotary blade, comprise handle of a knife, cutter hub and cutter head, and described cutter hub comprises the knife back and blade, the described knife back and blade are circular arc.
As a kind of prioritization scheme, described blade width radially from handle of a knife to cutter head reduces successively.
As a kind of prioritization scheme, described blade two sides are obliquely installed.
As a kind of prioritization scheme, the width of the described knife back is greater than the width of blade.
As a kind of prioritization scheme, on the outer surface of the described knife back, be provided with reinforcement.
As a kind of prioritization scheme, described reinforcement be shaped as circular arc.
As a kind of prioritization scheme, the two sides of described cutter head are obliquely installed.
As a kind of prioritization scheme, the inner surface of described cutter head is obliquely installed.
The utility model is taked above technical scheme, has the following advantages: cutter hub comprises the knife back and blade, thereby cutter hub intensity is improved greatly, not fragile in use procedure, long service life; While using this cutter farming, tilling depth deepens 50% than original cutter, and the knife back and blade are circular arc, and the rhizome of crops is difficult for being wound on cutter hub, has greatly improved operating efficiency.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of rotary blade in the utility model embodiment;

Accompanying drawing 4 is the vertical view of cutter head in accompanying drawing 1;
The structural representation of another structure that accompanying drawing 5 is cutter hub.
In figure:
1-handle of a knife; 2-cutter hub; The 21-knife back; 22-blade; 23-reinforcement; 3-cutter head.
Embodiment
Embodiment 1: as shown in Figure 1, a kind of rotary blade, a kind of rotary blade, comprises handle of a knife 1, cutter hub 2 and cutter head 3, and described cutter hub 2 comprises the knife back 21 and blade 22, and the described knife back 21 and blade 22 are circular arc.
Described blade 22 reduces to cutter head 3 width radially successively from handle of a knife 1.
As shown in Figure 2, described blade 22 two sides are obliquely installed, and can adjust as required the size of the angle of blade 22 both sides.
As shown in Figure 3, the width of the described knife back 21 is greater than the width of blade 22, has greatly strengthened the intensity of cutter hub 2.
The two sides of described cutter head 3 are obliquely installed formation triangle.
The inner surface of described cutter head 3 is obliquely installed, and can adjust as required the size at the inner surface angle of inclination of cutter head 3.
Embodiment 2: on the outer surface of the described knife back 21, be provided with reinforcement 23, described reinforcement 23 be shaped as circular arc, can further increase the intensity of cutter hub 2 by reinforcement 23.
Other structures are identical with embodiment 1.
