Abstract
The invention discloses a kind of weeding knife, including ontology, interconnecting piece, blades；It is provided with mounting hole in the ontology, is connect for the installation with motor；From ontology, two sides are symmetrically extended the weeding knife to the left and right；The ontology connects blade by interconnecting piece；It is provided with airflow hole on the interconnecting piece, to guide air-flow, reduces windage effect when high speed rotation；The blade includes two the first blades and the second blade, and two the first blades extend outwardly since interconnecting piece both sides of edges respectively, to the second blade of connection, constitutes continuous knife edge；Angle between first blade and the edge extension line of ontology is A, this angle is at 15-20 °, and herbicidal effect is more excellent at this time, is most saved the strength.Two sides blade is symmetrical arranged, and after the edge wear of side, can be worked on the blade for continuing to use the other side after flange；The airflow hole of interconnecting piece is arranged, and guides air-flow, reduces windage effect when high speed rotation.
Description
Technical field
The present invention relates to a kind of weeding knifes.
Background technique
Weeder has a weeding knife, is driven by a motor weeding knife rotation and the grass to be removed is cut off, but due in weeding
In the course of work, weeding knife is easy to touch the hard objects of stone one kind, will lead to weeding knife abrasion and even damages, in addition removes
Careless knife motor drive under high speed rotation when can because of windage caused by direction deviation.
Summary of the invention
Present invention aim to provide a kind of improved weeding knife, help to solve the above problems.
The present invention adopts the following technical scheme:
A kind of weeding knife, including ontology, interconnecting piece, blade；
It is provided with mounting hole in the ontology, is connect for the installation with motor；
From ontology, two sides are symmetrically extended the weeding knife to the left and right；
The ontology connects blade by interconnecting piece；
It is provided with airflow hole on the interconnecting piece, to guide air-flow, reduces windage effect when high speed rotation；
The blade includes two the first blades and the second blade, and two the first blades are opened from interconnecting piece both sides of edges respectively
Beginning extends outwardly, and to the second blade of connection, constitutes continuous knife edge；
Preferably, the angle between the first blade and the edge extension line of ontology is A, this angle is removed at this time at 15-20 °
Careless effect is more excellent, most saves the strength.
The beneficial effects of the invention are as follows；.
1, two sides blade is symmetrical arranged, can be to continue to use the blade of the other side after flange after the edge wear of side
It works on；
2, the airflow hole setting of interconnecting piece guides air-flow, reduces windage effect when high speed rotation.
Detailed description of the invention:
Attached drawing 1 is the schematic diagram using desktop.
In figure, 1 is ontology, and 11 be the mounting hole on ontology, and 2 be interconnecting piece, and 21 be the airflow hole on interconnecting piece, and 3 be knife
Body, 31 be the first blade, and 32 be the second blade；
Specific embodiment:
The present invention will be further described with reference to the accompanying drawings and detailed description:
In Fig. 1, it is provided with mounting hole 11 in ontology 1, is connect for the installation with motor, weeding knife is from ontology two sides to the left and right
It is symmetrically extended；
Ontology 1 connects blade 3 by interconnecting piece 2；
It is provided with stomata 21 on interconnecting piece 2, is used as guidance air-flow, reduces windage effect when high speed rotation；
Blade includes two the first blades 31 and the second blade 32, and two the first blades 31 are respectively since interconnecting piece two sides
Extend outwardly, to the second blade 32 of connection, constitutes continuous knife edge；
Angle between first blade 31 and the edge extension line of ontology 11 is A, this angle is at 15-20 °, the effect of weeding at this time
Fruit is more excellent, most saves the strength.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
