Abstract
The utility model provides a mowing blade and a mower using the mowing blade. The mowing blade comprises a blade body, a mounting hole used for being mounted on a mower is formed in the center of the blade body, cutting edges which are symmetrical about the center are arranged on two side faces of the blade body, the blade body comprises two arc sections which are symmetrically distributed about the center, and the cutting edges are arranged on outer convex surfaces of the two arc sections respectively. During the mowing process, if the hard root objects are encountered, the blade body can be used for cutting the hard root objects, and the phenomenon that the blade body is broken easily due to the fact that the cutting force is high.
Description
Technical Field
The utility model relates to a mowing equipment technical field, concretely relates to mowing blade and use this mowing blade's tea garden lawn mower.
Background
During the planting process of agriculture, weeds in the field can absorb limited fertilizers in soil, so that the growth of crops is directly influenced, and the yield of the crops is reduced. In order to avoid the influence of weeds on crops, weeding operation is required. Traditional weeding operation mainly relies on the manual work, and the inefficiency of manual weeding operation, intensity of labour is big and the running cost is high.
Aiming at the technical problems, the weeding machine which has the advantages of improving the weeding operation efficiency and reducing the labor intensity and the operation cost appears on the market. A grass cutting blade is a core component in a lawn mower and its structure affects the cutting speed and cutting efficiency of the lawn mower. As shown in fig. 1, the conventional mowing blade includes a rectangular blade body 01, a mounting hole 011 for mounting on a mower is formed in the center of the blade body 01, auxiliary mounting holes 013 for assisting in mounting on the mower are formed in both sides of the mounting hole on the blade body 01 and are symmetrical with respect to the center, cutting edges 012 symmetrical with respect to the center are formed in both side surfaces of the blade body, and weeds are cut off by the cutting edges in the rotation process of the blade body 011. However, because the blade body is rectangular, that is, the blade body is a straight blade body, and the blade edge is also a straight blade edge, in the mowing process, if a tree root hard object is encountered, the blade body can be used for cutting the tree root hard object, and the phenomenon of breaking the blade body is easy to occur due to the large cutting force.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a mowing blade, which aims to solve the technical problem that the mowing blade in the prior art is easy to be broken when encountering tree roots and other hard objects; and simultaneously, the utility model aims at still providing an use tea garden lawn mower of above-mentioned mowing blade.
In order to achieve the above purpose, the utility model discloses a technical scheme that grass cutting blade adopted is: the mowing blade comprises a blade body, wherein a mounting hole used for being mounted on a mower is formed in the center of the blade body, cutting edges which are symmetrical about the center are arranged on two side faces of the blade body, the blade body comprises two arc sections which are symmetrically distributed about the center, and the cutting edges are arranged on outer convex surfaces of the two arc sections respectively.
Preferably, the blade body is provided with auxiliary mounting holes symmetrically distributed about the center on two sides of the mounting hole for assisting in mounting on the mower.
Preferably, the blade body has a length of 54 cm.
The utility model discloses a technical scheme that tea garden lawn mower adopted is: the mower comprises a mowing blade, wherein the mowing blade comprises a blade body, a mounting hole used for being mounted on the mower is formed in the center of the blade body, cutting edges which are symmetrical about the center are arranged on two side faces of the blade body, the blade body comprises two arc sections which are symmetrically distributed about the center, and the cutting edges are arranged on outer convex faces of the two arc sections respectively.
Preferably, the blade body is provided with auxiliary mounting holes symmetrically distributed about the center on two sides of the mounting hole for assisting in mounting on the mower.
Preferably, the blade body has a length of 54 cm.
The utility model has the advantages that: the utility model discloses a blade body includes and is two segmental arcs of symmetric distribution about the center, is equipped with the cutting edge on the outer convex surface of two segmental arcs respectively, like this in the operation of mowing, if when meeting the hard thing of root class, the blade body relies on the evagination arcwall face slip of two segmental arcs to cut past, very big reduction blade body and the hard dynamics of cutting between the hard thing of root class to can effectively alleviate the technical problem that the blade was interrupted.
