Abstract

The utility model relates to a toothed rotary blade which comprises a blade handle, a mounting hole, a blade body, a blade edge and a blade back. The blade handle is provided with the mounting hole, and the blade body comprises the blade edge and the blade back. Due to the fact that the blade edge is in a toothed shape, the blade feeding contact area is reduced, the ground entering resistance of the rotary blade is effectively reduced, the toothed blade edge can effectively break weeds and straw heads, soil crashing and tillage efficiency can be improved, and hard fields can be tilled more easily.

Description

A kind of tooth is strengthened rotary blade
Technical field
The utility model relates to a kind of cutter of agricultural machinery mini-size tillage machine, relates in particular to a kind of dentation rotary blade.
Background technology
Mini-size tillage machine has simple in structure, operation light and flexible, volume is little, lightweight, be applicable to paddy field, nonirrigated farmland, sugarcane field, vegetable garden, orchard, the local uses such as tobacco ground, only need to change farm machinery just can carry out rotary tillage, intertillage, hack, trench digging, ridging, ridging, the operation of the kind more than 20 such as plastic film mulch, be particularly suitable for some mountain areas, the ploughing work of some little fields, when rotary tillage process is carried out in field, with be all traditional rotary blade, in some relatively field farming of hard, because of under these rotary blades during cutter the contact area to field of cutting edge large, be difficult for eating mud, mud smashing effect is undesirable, and than being easier to twine grass, twining straw head.
Summary of the invention
The purpose of this utility model is to provide a kind of can interrupt weeds, straw head, mud is eaten in hard field and be easy to a kind of dentation rotary blade.
The technical scheme that the utility model is taked, a kind of tooth is strengthened rotary blade, comprises handle of a knife, installing hole, cutter hub, blade, the knife back; Described handle of a knife is provided with installing hole, described cutter hub comprises blade, the knife back, described blade is dentation, effectively reduced rotary blade enter ground resistance, described installing hole diameter D is 11mm, described handle of a knife width B 1 is 25mm, described handle of a knife thickness H1 is 6mm, described cutter hub width B 2 is 42mm, and the thick H2 of the described knife back is 5mm, and described blade width of edge H3 is 1mm; Blade is dentation, has reduced the contact area that enters cutter, so effectively reduced rotary blade enter ground resistance, required power power diminishes, the Oscillation Amplitude of mini-size tillage machine also diminishes, the mini-size tillage machine labour intensity that operates also diminishes like this, operates and is easy to; The dentation blade of rotary blade can effectively interrupt weeds, straw head, improves hack and farming efficiency, and the hard field that the rotary blade with traditional is difficult to farming, becomes and be easy to the utility model farming.
The beneficial effects of the utility model are: effectively reduced rotary blade enter ground resistance, easily interrupt weeds, straw head, improved hack and farming efficiency.
Accompanying drawing explanation
Fig. 1 is that overall structure master of the present utility model looks schematic diagram;
Fig. 2 is overall structure schematic top plan view of the present utility model;
Fig. 3 is the A-A cross-sectional schematic of Fig. 1.
Mark in figure: handle of a knife (1), installing hole (1a), cutter hub (2), blade (2a), the knife back (2b).
Embodiment
Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is further described.
As shown in the figure: a kind of tooth is strengthened rotary blade, comprises handle of a knife, installing hole, cutter hub, blade, the knife back; Described handle of a knife (1) is provided with installing hole (1a), described cutter hub (2) comprises blade (2a), the knife back (2b), described blade (2a) is dentation, effectively reduced rotary blade enter ground resistance, described installing hole (1a) diameter D is 11mm, described handle of a knife (1) width B 1 is 25mm, described handle of a knife (1) thickness H1 is 6mm, described cutter hub (2) width B 2 is 42mm, the thick H2 of the described knife back (2b) is 5mm, and described blade (2a) width of edge H3 is 1mm; Blade (2a) is dentation, has reduced the contact area that enters cutter, so effectively reduced rotary blade enter ground resistance, required power power diminishes, the Oscillation Amplitude of mini-size tillage machine also diminishes, and the mini-size tillage machine labour intensity that operates also diminishes like this, operates and is easy to; The dentation blade (2a) of rotary blade can effectively interrupt weeds, straw head, improves hack and farming efficiency, and the hard field that the rotary blade with traditional is difficult to farming, becomes and be easy to the utility model farming.
