Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery parts, in particular to a lawn mower blade. Background Art
[0002] A lawn mower is equipped with a lawn mower blade. The lawn mower blade includes an installation ring and a plurality of blades. The blades have a cutting edge facing forward. During use, the installation ring is installed on the rotating shaft of the lawn mower, enabling the cutting of grass.
[0003] During the mowing process, sometimes relatively hard branches, such as tree branches, etc., may be encountered. In the prior art, the installation ring and the plurality of blades of the lawn mower blade are integrated. Such a lawn mower blade has the disadvantage of being easily damaged, affecting the service life of the entire lawn mower blade. Additionally, when one blade is damaged, the entire lawn mower blade cannot be used and needs to be replaced as a whole, increasing the usage cost. Summary of the Invention
[0004] The purpose of the present utility model is to address the above-mentioned disadvantages and provide a lawn mower blade that is not easily damaged and reduces the usage cost.
[0005] The technical solution of the present utility model is implemented as follows: A lawn mower blade includes an installation ring and a plurality of blades. The feature is that: There is a circle of outwardly protruding installation ring ribs around the installation ring. The installation ring ribs and the installation ring are integrated. There is a rubber ring around the installation ring ribs. The inner side of the rubber ring has a groove that fits the outer circumference of the installation ring ribs. This groove is the rubber ring groove. The rubber ring groove is installed on the installation ring ribs. The rubber ring has a plurality of rubber ring perforations. One side of the blade has a blade perforation. Screws are passed through the rubber ring perforations and the blade perforations to install the blade around the rubber ring. The plurality of blades are arranged in a circumferential array around the rubber ring.
[0006] Furthermore, the rubber ring includes a rubber inner ring and a rubber outer ring. The rubber inner ring and the rubber outer ring are connected by connecting ribs arranged at intervals. And the rubber inner ring, the rubber outer ring, and the connecting ribs are of an integrated structure. The rubber ring groove is on the rubber inner ring. The rubber ring perforations are on the rubber outer ring.
[0007] Furthermore, the blade has a through hole.
[0008] Furthermore, the width of the rubber ring is not less than 5 cm.
[0009] Furthermore, the length of the connecting ribs is not less than 3 cm.
[0010] The beneficial effect of the present utility model is: Such a lawn mower blade has the advantages of not being easily damaged and reducing the usage cost. Description of the Drawings

[0017] The present utility model will be further described below with reference to the accompanying drawings.
[0018] As shown in Figure 1 , 2 , a lawn mower blade includes a mounting ring 1 and a plurality of blades 2. The blade has a cutting edge 21 facing forward. The feature is that: a circle of outward - protruding mounting ring ribs 11 is provided around the mounting ring. The mounting ring ribs and the mounting ring are integral. A rubber ring 3 is provided around the mounting ring ribs. The inner side of the rubber ring has a groove that fits the outer circumference of the mounting ring ribs. This groove is the rubber ring groove 31. The rubber ring groove is installed on the mounting ring ribs. The rubber ring has a plurality of rubber ring perforations 32. One side of the blade has a blade perforation 22. The blade is installed around the rubber ring by passing a screw 4 through the rubber ring perforation and the blade perforation. The plurality of blades are arranged in a circumferential array around the rubber ring.
[0019] Since a rubber ring is provided between the blade and the mounting ring in the present utility model, during the process of cutting grass with the lawn mower blade, if encountering a tree branch, there is a buffering process, which can reduce the damage of the lawn mower blade of the present utility model and achieve the purpose of the present utility model; in addition, when one blade is damaged, it can be replaced, saving costs.
[0020] Furthermore, as shown in Figure 2 , 3As shown, the rubber ring includes a rubber inner ring 33 and a rubber outer ring 34. The rubber inner ring and the rubber outer ring are connected by connecting ribs 35 arranged at intervals, and the rubber inner ring, the rubber outer ring and the connecting ribs are of an integral structure. The rubber ring groove is located on the rubber inner ring, and the rubber ring perforation is located on the rubber outer ring.
[0021] With the above settings of the present utility model, better protection effects can be achieved.
[0022] Furthermore, the blade has a through hole 23.
[0023] With the above settings of the present utility model, the blade has better heat dissipation effects.
[0024] Furthermore, the width D of the rubber ring is not less than 5 cm.
[0025] Furthermore, the length d of the connecting rib is not less than 3 cm.
[0026] The above are only specific embodiments of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
