Description

Hardened durable mowing saw blade

Technical Field

The utility model relates to the technical field of saw blades, in particular to a hardened durable mowing saw blade.

Background

A mower is a machine for cutting pasture or trimming garden plants, and generally, the mower comprises a long handle part, a motor is arranged at the front end of the handle part, a power output shaft of the motor is vertical, and a blade is fixed on the power output shaft of the motor. In operation, the blade rotates after the motor is operated to cut the roots of grass or shrubs. The defects are that: when grass or shrubs are cut, weeds and some thinner branches are easy to wind around the motor, and the weeds and the thinner branches need to be manually removed, so that the cutting efficiency is affected.

Disclosure of Invention

The utility model mainly aims to provide the hardened durable mowing saw blade, which not only avoids weeds from winding a motor, but also is matched with the fourth blade to accelerate cutting efficiency by arranging the first blade body, the second blade body and the third blade body.

In order to solve the technical problems, the utility model discloses a hardened and durable mowing saw blade, which comprises the following components: a substrate; the assembly hole is arranged in the center of the substrate; the radiating holes are arranged on the substrate at uniform intervals; limiting rings which are arranged outside the assembly holes and are uniformly spaced; the first mounting groove, the second mounting groove and the third mounting groove are respectively arranged on the limiting ring from top to bottom; the first cutter body is arranged on the first mounting groove; the second cutter body is arranged on the second mounting groove; the third cutter body is arranged on the third mounting groove; a fourth cutter body arranged outside the substrate; the chip grooves are arranged between the fourth cutter bodies at uniform intervals.

According to an embodiment of the present utility model, the number of the heat dissipation holes is 4 groups.

According to an embodiment of the present utility model, the number of the limiting rings is 6.

According to an embodiment of the utility model, the number of junk slots is 8.

Compared with the prior art, the method has the following technical effects:

1) Through setting up first cutter body, second cutter body and third cutter body both avoid weeds winding motor, with fourth cutter body cooperation quickening cutting efficiency again.

Of course, it is not necessary for any one product embodying the utility model to achieve all of the above technical effects simultaneously.
